Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to the dispensing of fluid,
and in particular, to the controlled dispensing of liquid fuel
through a nozzle assembly. The present invention relates to nozzle
assemblies for pumping mechanisms used for dispensing fuel for
automobiles. The present invention further relates to fuel
dispensing devices equipped with systems that enable anyone using
such devices to fuel an automobile with the ability to participate
in passive or interactive activities.
[0002] Automobile fuels, such as gasoline and diesel fuel, are
commonly marketed at commercial fuel outlets, such as service
stations and convenience stores. Such fuels conventionally have
been delivered through fuel dispensing systems. Such a system
typically includes a normally statically positioned pumping
mechanism, commonly called a "pump," together with a hose and a
nozzle. When the system is not in use, the nozzle normally is
positioned in a designated port or resting region on the pump, and
when use is desired, the nozzle is removed from its resting
position on the pump. The system normally provides for filling a
vehicle fuel tank with fuel through the nozzle by actuating a pull
lever or trigger mechanism located in a handle of the nozzle to
open a valve located within that nozzle. As a result, fuel can be
pumped from a storage tank, through the hose, through the nozzle,
out of a spout and into the fuel tank of an automobile. Fuel
dispensing system units have been designed so as to be
aesthetically pleasing, provide a wide variety of automated
functions, and be readily operable by consumers with relative ease.
Representative components of typical fuel pumping systems are forth
in U.S. Pat. No. 4,095,626 to Healy; U.S. Pat. No. 4,566,504 to
Furrow et al. and U.S. Pat. No. 4,687,033 to Furrow et al.
[0003] At so-called "self-service" gasoline stations, the customer
removes the nozzle from the pump, actuates the pump and operates
the nozzle so as to dispense the desired amount of fuel into the
fuel tank of his/her vehicle. Service station and convenience store
operators have used portions of the static pump regions of fuel
dispensing systems in order to provide information to the customer
and to receive information from the customer. For example, pumps
have been equipped with audio speakers, video display units,
television screens, static signage, microphones, push buttons,
printing units, and the like. As such, store operators can inform
customers of products and prices, relay messages to customers,
provide entertainment to customers, relay information regarding
pricing and purchases, print receipts and coupons, and the like.
Store operators also can provide a way for customers to engage in
games that allow the customers to be entertained or to play for a
prize or incentive. In addition, the customer can make fuel
purchase selections and provide information to the store operator
by pushing buttons in response to prompted questions or by voice
through a microphone. Furthermore, at the so-called "pay at the
pump" establishments, a customer using a credit card can complete a
purchase using a card reader positioned within the pump (e.g., by
using a magnetic readable, embedded chip or radio frequency
activated credit card). Representative fuel dispensing system units
are available from Gilbarco, Inc. See, also, U.S. Pat. No.
5,859,416 to Gatto and German Patent Application 4,100,214.
[0004] Numerous nozzle constructions for use with fuel dispensing
systems are commercially available. Various nozzle assemblies are
commercially available through Saber Equipment Corporation, Dover
Corporation, Healy Systems, Inc., Emco Wheaton Retail Corporation,
Catlow Incorporated and Husky Corporation. Numerous nozzle designs
and features have been described in the patent literature. See, for
example, U.S. Pat. No. 4,453,578 to Wilder; U.S. Pat. No. 4,682,714
to Wood; U.S. Pat. No. 4,993,460 to Robinson et al.; U.S. Pat. No.
5,007,468 to Wilder et al.; U.S. Pat. No. 5,127,451 to Fink, Jr. et
al.; U.S. Pat. No. 5,236,984 to Kaplan et al.; U.S. Pat. No.
5,267,592 to Koch et al.; U.S. Pat. No. 5,273,087 to Simpson et
al.; U.S. Pat. No. 5,365,984 to Simpson et al. and U.S. Pat. No.
5,992,479 to Simpson. Typical nozzle assemblies have die cast
aluminum body construction; and certain components, such as the
lever actuation assemblies, have been manufactured from steel.
Typical commercially available nozzle assemblies weigh in excess of
about 2 pounds, and frequently weigh from about 3 to about 4
pounds. For example, the NE Elite Automatic Nozzle which is
available from Catlow, Inc. weighs approximately 2.2 pounds; the
Husky X Mate Nozzle which is available from Husky Corporation
weighs approximately 2.4 pounds; the Husky V Nozzle weighs
approximately 4 pounds; and the Model 800 by Healy Systems, Inc.
weights approximately 3.5 pounds.
[0005] Certain nozzle assemblies possess hand guards, levers and
body sections that can be equipped with covers that are
manufactured from plastic materials. Typically, such covers or
"scuff guards" are snapped on, fitted over or screwed on to certain
regions of the nozzle assembly. Such covers can be manufactured
from pliable nylon materials or hard plastic materials.
Representative nozzle assemblies equipped with various plastic
components are commercially available as A4500, A4505, A4005 and
A4015 from Emco Wheaton Retail Corporation; Model 11A from Dover
Corporation; Model 600 from Healy Systems, Inc.; and Husky XS
Leader, Husky X Mate, Husky Amoca V-1, Convac, Husky V-34 and Husky
V nozzles from Husky Corporation. Certain nozzle assemblies, such
as the NE Elite Automatic Nozzle, the Inverted Vapor Recovery
Nozzle and the Elite Pre-Pay Nozzle (available from Catlow, Inc.)
possess body assemblies that are manufactured from cast aluminum,
but lever and hand guard portions that are manufactured from tough
nylon materials. A nozzle assembly possessing a thermoplastic
outerbody assembly has been available as Saber 1.0, Flow and Saber
1.5, Display from Saber Equipment Corp. See, also, U.S. Pat. No.
5,184,309 to Simpson et al. In addition, see U.S. Pat. No.
5,184,309 to Simpson et al.; U.S. Pat. No. 5,363,889 to Simpson et
al. and U.S. Pat. No. Des. 355,704 to Simpson et al.
[0006] Recently, several references have proposed using nozzle
assemblies as venues for sources of messages. See, for example,
those features set forth in U.S. Pat. No. 4,465,209 to Wilder; U.S.
Pat. No. 5,058,637 to Fell; U.S. Pat. No. 5,458,170 to Ferguson;
U.S. Pat. No. 5,806,217 to Alvern; U.S. Pat. No. 5,810,063 to
Alvern; U.S. Pat. No. 5,815,967 to Alvern; U.S. Pat. No. 5,865,340
to Alvern; U.S. Pat. No. 5,862,617 to Alvern; and U.S. Pat. No.
5,887,367 to Alvern. Of particular note are the Fueling Talker
electronic advertising boots that are marketed by DirectCast
Network, LLC. Those boots are fitted onto the nozzles of gasoline
dispensing systems. See, also, U.S. Pat. No. 5,184,309 to Simpson
et al. as well as those nozzle assemblies that are commercially
available as Saber 1.0, Flow and Saber 1.5, Display from Saber
Equipment Corp. See, also, UK Patent Application 2,147,273.
[0007] It would be highly desirable to provide a nozzle assembly
that can be used as a venue for a source of messages to customers
using such an assembly while filling an automobile with fuel. It
would also be desirable to provide a light weight, economical and
versatile nozzle assembly for dispensing fuel, such as gasoline or
diesel fuel, into fuel tanks, such as those of cars and trucks. It
would be desirable to provide nozzle assemblies (and particularly
nozzle assemblies having features that provide the user thereof
with the ability to engage in interactive activities) that can be
readily incorporated as components of fuel dispensing systems, and
particularly in the types of dispensing systems used at
self-service gasoline stations and convenience stores.
SUMMARY OF THE INVENTION
[0008] The present invention relates to a nozzle construction or
assembly for use with a fluid dispensing system, and particularly a
fluid system that includes a fuel dispenser and a fuel dispensing
hose. Such a type of nozzle assembly includes a connection means
for allowing connection of the nozzle assembly to the hose and for
allowing fluid flowing through the hose to flow into the nozzle
assembly. That nozzle assembly also includes a housing portion that
acts as a handle in order that the assembly can be grasped, held
and handled by one hand of a user thereof. That nozzle assembly
also includes a trigger mechanism, and such trigger mechanism
typically is located in the housing portion in order that a user
can grasp the assembly and operate the trigger mechanism with the
same hand simultaneously. That nozzle assembly also includes a
dispensing valve, and that dispensing valve is associated with the
trigger mechanism in order that operation of the trigger mechanism
provides opening and closure of the dispensing valve. That nozzle
assembly also includes a spout, preferably generally tubular in
nature, for allowing fluid dispensed through the nozzle assembly to
be delivered to the desired location (e.g., a container, vehicle
fuel tank, or other suitable receptacle). A preferred nozzle
assembly also includes a shut-off mechanism for ceasing the flow of
fluid through the nozzle assembly when the receptacle being filled
with fluid approaches its capacity. A preferred nozzle assembly
also includes a mechanism for collecting fuel vapors during those
periods of time that the nozzle assembly is being used to deliver
fuel.
[0009] A preferred vehicular fuel nozzle assembly in accordance
with this invention includes additive features, such as features
that allow anyone using those nozzle assemblies to participate in
passive or interactive activities. Typical users of such nozzle
assemblies are customers at a gasoline station or convenience
store. The nozzle assembly can be adapted to provide messages that
are available for the user's visual inspection. The nozzle assembly
also can provide sounds or an audio message to the user. Another
nozzle assembly provides information in the form of a "hard"
medium, such as a printed paper receipt or coupon. Such features
are particularly desirable in order to direct messages,
information, service features or advertising to customers of
self-serve automobile fuel.
[0010] In one aspect, the present invention relates to a fuel
dispensing device that is equipped with a system that enables
anyone using the device to listen sounds or to messages,
participate in an interactive activity, participate in a game or
survey, receive receipts or coupons, receive information from an
illuminated display or otherwise interact with the device, at
essentially the same time that the device is being used to dispense
fuel into a vehicle. The nozzle assemblies of the present invention
incorporate systems that provide for illumination for
advertisements, gathering of information, communicating of
information, creation of game-related activity, or delivery of
coupons or tickets that give anyone using such an assembly special
incentives or access to promotions, gifts or prizes. Such an aspect
of this invention provides a means for focusing the attention of a
self-serve gasoline customer towards the nozzle assembly and the
processes associated with the fueling of a vehicle. In addition,
because the communication can be interactive, the consumer can
provide input or a response, such as by responding to a survey or
by entering a contest. The system can collect, store and transmit
collected data and information, such as the frequency of use of the
nozzle assembly.
[0011] The present invention relates to a nozzle assembly capable
of providing the user to engage in passive or interactive
activities, as well as to a boot adapted to incorporate those
additive features and designed so as to fit on a nozzle assembly.
For example, a fuel dispensing nozzle assembly comprises a spout, a
handle for the spout, and a boot adapted for close conforming fit
over at least a portion of the fuel dispensing nozzle. The boot
incorporates a housing; and that housing preferably is integrally
surmounted on the top region of the boot. The preferred housing
incorporates a system for providing at least one interactive
activity. For example, the housing can comprise a system for
delivering a video message (e.g., as a graphic display), a system
for illuminating relevant regions of the nozzle assembly, a system
for conveying information (e.g., a push-button system), a system
for delivering coupons, or any combination of the foregoing.
Preferred nozzle assemblies also include a system for delivering a
sound or an audio message. Also preferred are systems that
incorporate a storage means for pre-printed coupons and a delivery
means for those pre-printed coupons; or a coupon printer and a
delivery means for printed coupons.
[0012] In a preferred aspect, present invention relates to a boot
adapted for fit over at least a portion of a fuel dispensing nozzle
for a vehicle, wherein the boot comprises a system for providing an
interactive game. That boot also can include components for
conveying audio sounds or information. In another aspect, the
present invention relates to such a boot comprising a system for
delivering coupons, as well as a system for conveying sounds or
audio information. The present invention further relates to a boot
comprising a system for providing an interactive game and a system
for delivering coupons. Any of those boots can possess a component
that provides illumination within or around those boots during
normal conditions of use, and those boots can include components
for providing display of video messages. The system can collect,
store and transmit collected data and information, such as the
frequency of use of the nozzle assembly equipped with the boot.
[0013] In another aspect, the present invention relates a method
for providing a user of a self service gasoline pump with reason to
travel to a location remote from the pump. As such, the method
involves having the convenience store or gasoline station
proprietor provide a self service gasoline pump possessing a nozzle
assembly. The pump is provided with a system that allows the user
to engage in an interactive activity, and that system can be
provided through the nozzle assembly. The user of the pump is
provided a prompt, causing that user to engage in an interactive
activity. The prompt and interactive activity can be provided
through the nozzle assembly. The pump provides a message to the
user encouraging that user to travel to an identified location
remote from the pump (e.g., the store or station associated with
that pump) to receive an incentive. The user that travels to that
identified remote location then is provided with information
associated with that incentive. For example, the user that travels
to the store or gasoline station may be awarded a prize.
[0014] Another vehicular fuel nozzle assembly in accordance with
this invention incorporates components constructed from plastic
materials, and certain nozzle assemblies can be constructed
primarily from plastic materials. Alternatively, significant
components of the nozzle assembly can be constructed primarily from
plastic materials. In one aspect, the present invention relates to
a nozzle assembly for dispensing fuel from a gasoline pump through
a hose, the nozzle comprising a generally tubular spout composed
primarily of a plastic material. In addition, the frame, handle,
trigger, and inner regions and channels of the nozzle assembly can
be composed primarily of plastic materials. Such a fluid dispensing
nozzle assembly provides numerous benefits, and is superior in many
regards relative to conventional nozzle assemblies that are
manufactured principally from metals, such as aluminum and steel.
Such nozzle assemblies are attractive, aesthetically pleasing, and
are comfortable to hold by hand when the surrounding weather
conditions are hot or cold. The nozzle assemblies of the present
invention are relatively light in weight. The thermoplastic outer
body and spout are rugged, and are designed so as to not corrode,
and be easy to maintain. The preferred nozzle assemblies possess a
relatively low number of movable or breakable parts, relative to
traditional nozzle assemblies manufactured principally from
aluminum and steel. The nozzle assemblies constructed primarily
from plastic materials are reliable, relatively inexpensive to
manufacture and maintain, and exhibit a desirable life-time during
periods and conditions of normal use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0030] Referring to FIG. 1, there is shown a representative
vehicular fuel nozzle assembly 3 of the present invention. The
nozzle assembly includes a standard fuel dispensing nozzle 6
including a frame 10, and a connector 12 to a hose 15 from a pump
(not shown), in order that fuel from the pump can pass from the
pump through the hose to within regions of the nozzle frame 10.
Numerous types of fuel dispensing nozzles are commercially
available. The nozzle assembly 3 includes a handle region 20 that
is adapted in order that anyone using the nozzle assembly can
readily grasp that assembly. The assembly also includes a trigger
25 or other suitable means for controlling the flow of fuel through
the assembly, as well as an optional manually operated control
lever 28 that is in mechanical communication with a shut off
apparatus within the nozzle frame. A generally tubular spout 31
provides a means for directing the dispensing of fuel to the
desired location. An optional wound wire 35 around the spout 31
provides a simple way to maintain positioning of the spout within a
fuel receptacle (not shown). Typically, the spout 31 is composed of
a metal material.
[0031] A boot 40 of the nozzle assembly 3 (which is shown partially
in phantom) is shown as having a one-piece frame, and the boot is
shown fitting over the nozzle frame 10 at a region downstream from
the trigger 25, but upstream from a significant length of the spout
31. If desired, it is possible for the boot 40 to fit over the
nozzle frame 10 and over a portion of that region of the hose 15
that is immediately adjacent the upstream end of the nozzle frame.
That boot 40 has a close conforming fit over a portion of the
length of the fuel dispensing nozzle 6; and that boot possesses a
housing 45 incorporating a communication system 48. That
communication system 48 incorporates various communication
components 54 that provide the ability for the user of the nozzle
system to participate in an activity. The communication components
54 can include one or more programmed electronic circuit boards, or
other means for allowing the user of the nozzle assembly to receive
and/or convey data or information. As such, passive, interactive
and informational functions can be performed in response to the use
of the nozzle assembly. Representative communication components 54
can include a system for identifying the user, a system for
conveying information from the user to a remote location, a system
for sensing and communicating current environmental conditions, an
interactive game system, a coupon dispensing system, a system for
delivering a sound or an audio message, a system for providing
visual information, and/or an illumination system. As such, games,
quizzes, surveys, and passage of information and promotional
materials can be carried out in conjunction with the use of the
nozzle assembly 3. The communication system also can include a
speaker 56 for providing sounds or an audio message to the user.
The communication system also can include, in addition to or in
conjunction with the speaker, a microphone (not shown) in order
that the user can convey audio information for transmission to a
remote location. The back wall or face 58, or other region of the
boot, is adapted to have a series of open pores or perforations 60,
or is equipped with a mesh, screen or other means to allow sound
from the speaker to exit the boot and sound from the user to enter
the boot and be picked up by the microphone. Preferably, the
speaker 56 faces out the back face 58 of the boot 40 in order that
sound emitted by the speaker is directed towards the location of
the user.
[0032] The top face 62 of the boot 40 possesses a viewing face 64,
that in one embodiment possesses a pad or face 66. The pad or face
66 can be decorated with designs, words, numbers, or other printed
indicia. A transparent protective cover 68 protects components
exposed on the viewing face 64 from being subjected to damage and
wear from exposure to natural elements. Representative transparent,
protective shield or sealing materials can include a thin sheet of
polymethylmethacrylate (e.g., Plexiglas) or polycarbonate (e.g.,
Lexan). The face 66 of the viewing face 64 includes a plurality of
lights 70.
[0033] The preferred nozzle assembly 3 also incorporates a
switching mechanism 78 for activation and deactivation of the
communication system 48. The nozzle assembly also can incorporate a
power source 84 for providing the power to operate the various
components of the communication system. The switching mechanism 78
is connected to the power source 84 by a conductive wire 86, or
other suitable connection means. The switch can be located in the
general location shown in FIG. 1, or elsewhere within the nozzle
assembly. The switch can be located within the boot, hidden from
the view of the user. For example, the switch can be incorporated
within the electronic circuitry of the communication components
54.
[0034] In a preferred aspect, the various components of the
communication system 48 are contained in the boot housing 45 in the
form of a removable cartridge. As such, the various electronics of
that system, the power source 84, the switching mechanism, and
other relevant components can be readily removed from the boot as
an integral component for updating, service or replacement. The
boot can be appropriately designed so that such a cartridge can
remain firmly in place within the boot during normal conditions of
use, while the boot can be manipulated so as to allow removal of
the cartridge therefrom. In a highly preferred aspect, the various
components are modular in nature, and various additive features can
be added, removed, interchanged or replaced within a particular
nozzle assembly.
[0035] The boot 40 is a component that fits over at least a portion
of the fuel dispensing nozzle 6. The boot typically is manufactured
from a plastic material, such as a thermoset or thermoplastic
material. Preferably, the boot is designed to be capable of fitting
over the nozzle frame and remain in place, as a result of the
design of the shape and size of its one-piece frame. Most
preferably, the boot frame is flexible or pliable in a nature, in
order that the boot can be slipped and readily fitted on the nozzle
frame 10, and generally conform to the overall shape of the nozzle
frame over which the boot fits. Representative boot designs and
configurations are of the types described in U.S. Pat. No.
5,058,637 to Fell; U.S. Pat. No. 5,458,170 to Ferguson and U.S.
Pat. No. 5,815,967 to Alvern, which are incorporated herein by
reference. Those patents describe boots possessing static message
platforms as well as systems for automatically playing messages or
sounds. Exemplary boot materials and components, as well as
exemplary boot designs are of the types that have been commercially
available from DirectCast Network, LLC, Alvern S. A., and M & M
Display, Inc.
[0036] The boot 40 most preferably has a close conforming (e.g.,
snug) fit relative to the remaining portion of the nozzle assembly
3. As such, the boot is maintained firmly in place over a desired
region or portion of the nozzle frame 10, under normal conditions
of use. Typically, the boot is maintained in place by friction fit,
and such a design provides an appropriate attachment means for the
boot to the front portion of the nozzle frame. As shown, the boot
fits over a portion of the nozzle frame in the region of the handle
portion where that handle portion meets the spout 31. The boot also
can be maintained in place relative to the remaining portion of the
nozzle assembly by one or more screws, clips, clamps, tabs,
adhesives, or other suitable connection means (not shown). Though
less preferred, the boot can have a frame having multiple piece
design or configuration. Such a design allows for pieces of the
boot frame to be fitted over the fuel dispensing nozzle, and
secured in place through the use of fastening devices (e.g., clamps
or screws), adhesives, or other suitable assembly means.
[0037] Boot systems provide for a particularly desirable way to
incorporate, in an efficient and effective manner, the features of
the present invention into virtually any nozzle assembly. A boot
can be readily designed to fit over and operate in conjunction a
nozzle assembly by a selection of the size, shape and configuration
of the boot. The boot can be designed so as to be readily fitted
over the nozzle assembly, and can be designed so as to be
aesthetically pleasing. Boot systems also can be designed to be
light in weight, and of a shape so that use of the nozzle assembly
is not rendered overly burdensome or complicated.
[0038] During use, the user removes nozzle assembly 3 from a fuel
pump (not shown), and the extreme end of the spout 31 is inserted
into the fueling port of a vehicle (not shown). Systems of the
present invention can be activated and deactivated by switching
mechanisms. Activation of switch 78 activates components of the
communication system in order that the interactive activity can
commence. As such, the user is provided with information while the
vehicle is being fueled. In addition, the user can engage in the
playing of a game or responding to a survey while using a nozzle
assembly. When, the use of the nozzle assembly 3 is complete
because the fueling process is complete, and the spout 31 is
removed from the fueling port, the switch 78 within the system is
operated to deactivate the system. Suitable timing mechanisms
located within the system can provide a desired lag time before the
system is activated or deactivated by operation of the switch.
[0039] The switching mechanism 78 can vary, and the communication
system can be activated and deactivated in a variety of ways. It is
desirable for the system to remain deactivated when the fuel pump
and nozzle assembly 3 are not in use. This provides maintenance of
the power available in the power source 84. The communication
system can be manually activated and deactivated by the customer or
other personnel associated with the use of the communication
components 54 of the communication system 48. The system also can
include, as an optional component, at least one fuse (not shown),
in order to deactivate the power supply from the power source to
other components of the system.
[0040] The communication system 48 can be adapted to provide for
activation and deactivation of the system from remote locations
(i.e., locations physically removed from the fuel pump and fuel
nozzle assembly). A manually operated switching mechanism can be
located at a remote location, such as within the gasoline station
or convenience store. Such a feature can provide activation and
deactivation in addition to the previously described switching
mechanisms; and such a feature can be used for safety and security
reasons. Thus, the operator of a gasoline station or convenience
store can activate and deactivate each system from a location
remote from the fuel pump (e.g., from within the
establishment).
[0041] The communication system 48 can be activated and deactivated
by the user by employing a push button 78 or other similar means
located on or near the nozzle or the pump. The switching mechanism
can be a manually operated switch, such as a push-button or toggle
switch, located on or near the pump or the nozzle assembly.
Representative types of touch pad technologies are described in
U.S. Pat. No. 5,657,004 to Whittaker et al. The switch also can be
activated and deactivated by an electronic pre-programming means
and the use of an internally positioned integrated circuit clock
(not shown). As such, upon predetermined prompts or activity, the
switch can be activated and deactivated in accordance with a
switching mechanism controlled by a timing mechanism provided by
that clock. The selection and positioning of the switching
mechanism can vary, and can be a matter of choice.
[0042] In the preferred aspect, a switching mechanism (not shown)
located within housing 45 is activated when the nozzle assembly is
removed from the nozzle receptacle on the fuel pump (not shown), or
when the nozzle assembly is inverted so as to position the spout 31
into the fuel tank; and deactivated when the nozzle assembly is
brought to vertical, or near vertical position. That is, movement
of the nozzle assembly from the fuel pump receptacle to the fueling
port causes the system to be activated. Thus, the communication
system can be activated and deactivated by a switching mechanism
designed to sense the orientation of the nozzle assembly. Exemplary
switching mechanisms are mercury switches, such as those available
as Part No. 1800-1 from Assemtech Europe Ltd. Suitable switching
mechanisms are employed commercially by DirectCast Network, LLC in
its Fueling Talker vehicle fuel nozzle assembly boots.
[0043] A timer or motion sensor (not shown) located in the
communication system 48 can sense lack of attention relative to the
nozzle assembly; and an alarm (not shown) located within the
communication system can sound to alert the customer to remove the
nozzle from the fueling port of the vehicle to the appropriate
receptacle of the fuel pump. Such a safety feature alerts a
careless customer not to drive away from the pump with the nozzle
still inserted into the fueling port of his/her vehicle. The timer
or motion sensor can be provided as part of the electronics within
the circuitry of the communication components 54 within the
communication system 48. For example, the timer can be incorporated
within a microprocessor (not shown).
[0044] In a preferred aspect of the present invention, the nozzle
assembly 3 includes a small speaker 56, other suitable audio
communication means. The speaker provides sounds and audio messages
that are provided from circuitry within the communication system.
Thus, the speaker can produce the audio output associated with the
playback of a pre-recorded message that is stored within the
communication system, and/or from a receiver within the
communication system. The speaker is appropriately connected with
conductive wires (not shown), or other suitable connection means.
Most preferably, the audio communication is provided from a source
within the nozzle assembly through a speaker located within the
nozzle assembly. An exemplary speaker has a 5 watt, 7,000 Hz
construction and possesses a mylar cone. Such a type of speaker is
commercially available as PR504N-7-8 from RDI Electronics. Suitable
audio communication mechanism, and the control therof, are employed
commercially by DirectCast Network, LLC in its Fueling Talker
vehicle fuel nozzle assembly boots. Other types of audio message
system components are described in U.S. Pat. No. 4,984,098 to
Buntsis; U.S. Pat. No. 5,624,822 to Vogelman et al. and U.S. Pat.
No. 5,671,331 to Croley.
[0045] Hard wired and wireless systems can be programmed, operated
and controlled from locations remote from the fuel dispensing
device. In such a manner, information and commands can be
transmitted and received over significant distances. Such systems
are particularly desirable when the communication system 48
incorporates a microphone (not shown). As such, the user can
communicate by voice, and the information that is input through the
microphone can be transmitted to a remote location. Selection and
operation of an appropriate microphone can be a matter of
choice.
[0046] The communication system 48 can be hard wired. By this is
meant the various electronic signals are transmitted through
hardware components, such as electrically conductive materials, or
hardware components that are physically connected together to
provide transmission of electronic signals. If desired, such
signals can be conducted through fiber optic cables, or other
suitable transmission means. See, for example, UK Patent
Application 2,147,273.
[0047] Alternatively, the communication system 48 can be adapted to
receive commands and transmit information in a wireless manner. By
this is meant that electronic signals can be transmitted and
received through electromagnetic radiation (e.g., radio wave,
infrared or microwave signals). As such, communication from the
nozzle assembly to a remote location can be accomplished using a
system possessing suitable electromagnetic radiation transmitter
and receiver components that are designed to communicate with
corresponding receivers and transmitters. Appropriate receiving
components most preferably include an antenna Various wireless
systems are described in EDN, Febr. 16, 1998 and U.S. Department of
Commerce publication "NTIA Special Publication 95-33 Survey of
Rural Information Infrastructure Technologies, September 1995,
Wireless Systems and Technology." A wireless system that provides
for radio frequency communication to and from the system can
incorporate a BSN 6040 Processor and a TRF 6001 Transceiver from
Texas Instruments. A wireless local area networking system
operating under a Bluetooth protocol that is available from
Ericsson also can be employed.
[0048] The communication system 48 can incorporate a global
positioning system (GPS) (not shown), and as such, the user can
prompt questions regarding location. Alternatively, the customer
can press a button requesting directions; and while that customer
completes fueling his/her vehicle, the request can be conveyed to a
central processing location within the gasoline station or
convenience store; and a custom map or directions can be printed
out for the customer on a printer located within the station or
store.
[0049] The communication system 48 can include the electronics
associated with the reception of the electromagnetic signals
associated with wireless telephonic communication. Digital or
analog wireless telephonic communication systems also can be
employed. As such, information accessible via the Internet, or
other computer network system, can be provided to the user of the
nozzle assembly. If desired the transmission of the network related
information is controlled or provided from a remote source. Such a
source can be a central control location, or a location within the
immediately associated gasoline station or convenience store. The
particular transmission equipment and the programming associated
with the delivery and presentation of the desired information from
a computer network will be readily apparent, and the selection
thereof will be a matter of choice.
[0050] In a preferred aspect of the present invention, the nozzle
assembly 3 is illuminated, at least to some degree in a relevant
region thereof. As such, there is provided lighting via electrical
or other illumination or illuminant or luminous system, such as a
series of lights 70. Illumination can be provided for example, by
lighting on, in, around or behind the game face 64 of the nozzle
assembly. The illumination can be provided by electrical based
illumination provided by electrical current from a source such as a
battery 84. Illumination can be provided by or from fluorescent
materials, incandescent materials, ultraviolet or infrared
materials, laser sources, fiber optic materials, photosensitive
materials, materials possessing dye patterns, chemically reactive
systems, holographic materials, electroluminescent materials,
photoluminescent materials, photochrominescent materials,
bioluminescent materials, sonolumininescent materials, light
emitting diodes (LED), field emitter displays (FED), liquid crystal
displays (LCD), plasma display panels (PDP), or the like. Such
materials are available from commercial sources, and the selection
and adaptation for use of those materials, can vary depending upon
the display and effect that is desired. See, also, U.S. Pat. No.
5,184,309 to Simpson et al. and UK Patent Application 2,147,273.
The illumination can be such that an alpha-numeric display (e.g.,
as through a LCD system) can be provided. Most preferably, the
illumination provides a graphic display (e.g., pictures, symbols,
and the like). As such, preferred nozzle assemblies include a
device for providing a graphic display. If desired, the
communications components 54 include a graphic display device to
provide visual information as well as an audio system to provide
audio messages, and most preferably, the timing associated with the
video and audio messages is synchronized. Such synchronization can
be accomplished through the use of a microcontroller (not
shown).
[0051] The nozzle assembly 3 can be equipped with a counter or
counting mechanism (not shown), or other means for sensing and
recording the use of the nozzle assembly. Of particular interest
are counter mechanisms that sense and record the number of times
that a nozzle assembly is employed. Thus, for nozzle assemblies
providing audio or visual messages, such as advertising, relevant
personnel can observe and track the frequency of delivery of that
message to customers. Information regarding the number of uses of
the nozzle assembly, the various times of day that the nozzle
assembly is used, the period of time that the nozzle assembly is
used, and other information regarding exposure of the nozzle
assembly to customers, can be recorded. That information can be
stored within the nozzle assembly itself, or relayed (e.g., by
electronic means) to another location, for data collection and
analysis.
[0052] Counter mechanisms can be mechanical or electronic in
operation. Mechanical trip systems typically use a cog that trips a
lever resulting in incremental addition with a counting system.
Electronic systems typically use an interrupt circuit to activate a
counting and storage device. A preferred counter mechanism
incorporates an electronic counter that employs a COP 8 Series
Micro Controller form National Semiconductor. Such as counter
mechanism can detect power activation as a result of activation of
a mercury switch, and store the detected information as an
incremental activation to a suitable data storage device (e.g., a
microprocessor located within the communication system).
[0053] The nozzle assembly 3 can be equipped with various other
optional features. The nozzle assembly can incorporate an
electronic device (not shown) that is capable of sensing electrical
ground from the nozzle assembly and through the hose 15. When that
device does not sense adequate ground, the nozzle assembly can be
rendered inoperable, or alternatively, a warning message (e.g., a
warning light or audio warning) can be delivered to the user. As
such, a service station operator then can take appropriate steps to
repair the pumping mechanism in order that proper grounding of that
pumping mechanism is accomplished. Such an optional feature is
desirable in that electrical ground is necessary in order to avoid
the build up of static electricity that may have the potential to
generate heat or spark sufficient to cause ignition of fuel vapors
in the vicinity of the pumping mechanism. Other safety devices,
such as carbon monoxide monitors, heat sensors, smoke detectors,
and the like, can be incorporated into the nozzle assembly. As
such, certain environmental conditions can be sensed, and
appropriate audio or visual alarms can be activated.
[0054] The communication system 48 of the nozzle assembly 3 is
rendered operable by a suitable power source 84. Most preferably,
the power source is a battery or series of batteries. Batteries can
be single use or rechargeable. An exemplary battery includes, for
example, a 4.8 volt lithium ion or nickel cadmium rechargeable
battery system available from Avex, Inc. Other exemplary batteries
are AA alkaline type batteries that are commercially available from
Eveready, Duracell or Rayovac. The power source for certain of the
components of the system also can include a suitable solar energy
power source, which can be used independently or in combination
with another internal or external power source. The battery
typically is positioned within the housing 45 of the boot 40, and
can be positioned within the communication system cartridge. It is
desirable for the battery to be located within the boot to be
easily accessible, in order that the battery can be readily
replaced or recharged. Optionally, the power source can be adapted
to receive power from an AC source, particularly for recharging a
battery-type power source.
[0055] The interactive system of the present invention has a
variety of advantages. The system can provide a customer using a
device incorporating such a system with increased awareness of
products in stock, as well as services and special items for sale.
The present invention allows for convenient communication of
information directly from and to the current user of the system. As
such, a customer can be presented with awareness of a wide range of
information, and because of the unique presentation of that
information directly to the customer at the pump. Further, the
illumination assists in providing an effective means for enhancing
the customer's attention to the message being conveyed. The
information can be rendered effective, diverse and entertaining
(e.g., for recreational or entertainment purposes). Thus, the
customer is encouraged to remain in the vicinity of the fuel
dispensing nozzle during the time that the nozzle is being used. As
such, attention to the dispensing of fuel is maintained, and safety
maintained.
[0056] The interactive system can allow the proprietors of a
convenience store or gasoline station to provide customers at such
establishments with reason to travel from the self service gasoline
pumps to stores, station buildings, or other locations remote from
the pumps. As such, the convenience store or gasoline station
proprietor provides a self service gasoline pump possessing a
nozzle assembly. The pump and/or nozzle assembly can be provided
with a system that allows the user with an ability to engage in an
interactive activity. The user of the pump and the nozzle assembly
is provided a prompt, causing that user to engage in an interactive
activity provided through the nozzle assembly. For example, a
communication system associated with the pump can provide the user
with an audio message and/or a message that is communicated
visually, or the user can be provided with a coupon. The user then
can engage in an interactive activity, such as play a game or
engage in a survey provided within that communication system. The
pump and/or nozzle assembly then can be used to provide a message
to the user encouraging that user to travel to an identified
location remote from the pump (e.g., the store or station
associated with that pump) to receive an incentive. That message
can be provided as an audio message provided through a speaker
located on the pump or on the nozzle assembly, or as a video
message provided on a video screen located on the pump or on the
nozzle assembly. The user that travels to that identified remote
location then is provided with information associated with that
incentive. For example, the user traveling to the store or gasoline
station may be awarded information about a prize for playing a
game, a user who has engaged in a survey may receive information
regarding a survey, or a user requesting directions can receive a
map.
[0057] Referring to FIG. 2, there is shown a boot 40 (shown
partially in phantom) that is exemplary of the design of a boot of
the present invention. The exemplary boot includes a housing 45
that preferably has been integrally molded into the boot and
thereby forms a part of that boot. The housing 45 is utilized to
house the various components of the communication system 48, such
as the communication components 54, speaker 56 and the battery 84.
The boot is overall generally tubular in shape and is generally
hollow to provide an open chamber extending longitudinally
therethrough. As such, the upstream or back end 110 has a relative
large opening 112 in order to allow fit over the handle region of
the nozzle assembly, and the downstream or front end 115 has a
relatively small opening 117 in order to allow fit over a portion
of the spout of the nozzle assembly. Although not shown, the boot
can possess regions on its top region 120, or on the right and/or
left sides thereof for the positioning of placards for conveying
text messages (e.g., advertising messages).
[0058] The housing 45 in the upper region of boot 40 provides an
open chamber or hollow region into which communication components
54 of the communication system 48 can be positioned. The back wall
or face 58 is adapted to have a series of open pores or
perforations 60, or is equipped with a mesh, screen or other means
to allow sound from the speaker 56 to exit the boot and sound from
the user to enter the boot and be picked up by the microphone. The
housing possesses a bottom 124, front 126, back 58 and side walls
to support those components. The housing also can have a portion of
the top region thereof provided as an opening to allow portions of
certain components to protrude. The housing can be adapted to have
movable or releasable portions to allow easy removal and insertion
of components, such as for reconditioning and upgrading of selected
components. In addition, the chamber can be configured in such a
customized shape to allow for a pre-determined, organized
positioning of the various components therein.
[0059] The boot 40 includes a communication system 48 possessing a
viewing face 64. The viewing face includes a pad or face 66, and a
plurality of small lights 70. Mechanical and/or electronic
components of the game system can be positioned in an upper boot
region 127 between the game face 66 and the communication system
48. A transparent protective cover 68 covers and protects the
components (e.g., lights 70) exposed on the viewing face 66. The
transparent face is adapted to be held in place relative to the
remaining portion of the boot by friction fit within a molded
groove within the boot and/or using a suitable adhesive.
[0060] Referring to FIG. 3, the boot 40 is viewed from the front
end 115 or spout end thereof. The boot possesses an opening 117 in
its lower end through which the spout (not shown) extends. The
upper portion of the boot possesses the communication system 48
supporting the roulette-type game. Components of the communication
system 48 can be positioned in housing 45 (shown in phantom) as
well as the upper region 127 of the boot.
[0061] Referring to FIG. 4, a cross section of the boot 40 is seen.
The boot incorporates a hollow region 140 to accommodate the nozzle
frame (not shown) of the vehicular fuel dispensing nozzle over
which the boot is positioned. The hollow region 140 is located
below the housing 45 for the communication system 48. For the
alternate layout of the communication system 48 that is shown,
alternate designs of the battery 84 and the integrated circuit
board 142 are shown, and the speaker is not shown. The battery 84
is shown as being connected to the integrated circuit board 142 of
the communication system 48 by conductive connection wire 144.
[0062] Referring to FIG. 5, there is shown a top view of a portion
of the nozzle assembly 3, including boot 40. That view of the
nozzle assembly is comparable to that observed by anyone using the
nozzle assembly under normal conditions of use. The nozzle assembly
incorporates a game system. There is shown boot 40 and housing 45
incorporating a communication system 48 that is selected so that
game face 66 that is shown in FIG. 3 appears as a roulette-type
game. A series of perforations 60 on the top and back face of the
boot provides sound from a speaker located inside the boot to
emanate from the boot. Printed indicia (e.g., game directions,
pictures, advertising information, logos, numbers or letters) on
the game face are shown as printed numerals from 1 to 16. For the
exemplary roulette-type game, the face of the communication system
includes a series of lights 70, and each light is associated with a
corresponding designated number or symbol. The flashing of the
individual lights simulate the movement of a ball on roulette
wheel. The individual lights are electronically controlled such
that when stimulated, each light is illuminated momentarily in
quick sequence and in so doing simulates a ball's position and
final stationary position on a roulette wheel. Alternatively, a
dice game can be simulated in a similar manner by providing a
configuration of lights in which there are six lights, and the
electronics of the game are designed to control the lights in order
that certain lights simulate the dots of the face of a die. For
example, if two lights are lit, then the die would show a two, or
the location where the light remains lit indicates the winning item
that is graphically displayed.
[0063] A desired game can be readily provided through the use of an
appropriately programmed integrated circuit. The exact electronic
components associated with such types of games are not complex, and
suitable types of electronics can be found in many marketed
entertainment and recreational products. The electronic components
also can be readily assembled from commercially available kits of
relevant component parts. Known electronics can be programmed to
provide computer games, such as Pac Man or Video Poker. Lottery
type games, card games also can be provided. Other games can
include simulated sports games, such as car racing, baseball,
football, basketball, soccer, hockey, and the like. Other games can
include those types of games found in commercially available hand
held electronic systems, and can be viewed using suitable viewing
screens. Such types of games typically are presented using LED, or
preferably LCD, types of technologies. Yet other games can include,
for example, quizzes regarding trivia (e.g., sports or movie
quizzes). Preferred games are those that can be carried out in the
size available on the nozzle assembly that is employed in
accordance with the invention. Although less preferred and less
practical, games also can include checkers, dominos, chess, dice,
poker, choose a number, and the like, or "take-off" games based on
those types of games.
[0064] Games can include games of chance, or promotional games
designed to provide a souvenir, discount, premium or reward to a
customer. Participation in the games can be for recreational or
entertainment purposes, or can involve incentive or promotional
features, such as the awarding of gifts, prizes, or the like.
Surveys can be conducted for entertainment value, and the results
can be compiled and published at a later date. As such, the
consumer is provided with some additional reason or desire to
return to a particular service station or convenience store. In
addition, the system can be programmed so as to allow the user to
participate in the playing of a game if that user listens to a
particular message or provides input to a survey.
[0065] Referring to FIG. 6, there is shown a top view of a portion
of the nozzle assembly 3. There is shown boot 40 and housing 45
incorporating a communication components 54 that has the form of a
selection system 146. That is, the nozzle assembly 3 includes a pad
or face 66 that is adapted to be an information collection module.
The user can use keys 146 on the face of the pad 66 to answer
questions or prompts provided on the face of that pad, from the
pump, from audio communication or from a stationary placard. Within
housing 45 of boot 40 is positioned a message board. As shown, the
message board allows the user to answer "yes" or "no". Additional
selections can include "erase," "restart," "replay," and the like,
in order to allow the user to control the desired input and output
associated with the nozzle assembly. Other answer selections can be
provided, and the specific selection can be a matter of choice.
Such a design is particularly desirable for allowing the user to
engage in the playing of an interactive game or in responding to a
survey. In addition, the design is desirable for allowing the user
to select the language that audio and/or video messages are
conveyed. For example, the user can request that information to be
provided in English, Spanish, German or French; or that written
information be provided in a special character or text, such as
Japanese or Russian. Alternatively, the message board can possess a
dial that can be used by the customer to control the volume of the
audio system associated with the nozzle assembly. For example, the
dial can control the output through an amplifier associated with
the speaker of the nozzle system. See, also, for example, UK Patent
Application 2,147,273.
[0066] The communication system 48 can be adapted to receive
various types of information from the user, and for the user to
input information in various ways. The user can convey information
by pressing pressure sensitive keys 146 (e. g., such as keys on a
keypad or keyboard), touching a video touch screen, turning knobs,
by switching a toggle-type switch, or by employing other suitable
switching, triggering or selection means. See, for example, the
types of technologies described in U.S. Pat. No. 5,504,675 to
Cragun et al and U.S. Pat. No. 5,657,004 to Whittaker et al.
Information can be conveyed from coded systems, such as bar coded
systems, by providing the user with a bar coded identification
card, and by incorporating in an appropriate manner a corresponding
bar code reader into the boot. Exemplary types of bar code systems
are available from Portable Products, Inc., Sun Max and Intermeric
Technologies Corp. See, also, the types of technologies described
in U.S. Pat. No. 5,630,071 to Sakai et al. Other suitable systems
include those that incorporated the type of technologies associated
with the Mobil Speed Pass that are provided by Texas Instruments.
Information can be provided about a particular user, such as a
pre-approved user, by incorporating a finger or thumb print sensing
device into the boot. Visual information can be received by
incorporating a small video camera (not shown) into the boot. Audio
information can be received by incorporating a microphone (not
shown) into the boot. Voice or sound activation of the system can
be accomplished, for example, by using the types of technologies
available from Portable Product, Inc. For each of the foregoing
devices, the information received by those devices is appropriately
stored, but most preferably is transmitted to a remote location for
collection and processing. Transmission of those types of
information can be accomplished through the previously described
hard wire or wireless transmission mechanisms.
[0067] The communication components 54 can be adapted to receive
information through a counter or counting mechanism (not shown).
For example, for a communication system that offers the user a
choice to receive audio and/or video messages in a particular
language (e.g., English or Spanish), an electronic counter
mechanism can record the number of times that various selections
are made. In such a manner, the store operator is provided with a
way to gather certain demographic information surrounding the use
of the pump.
[0068] The communication system 48 can be adapted to receive
various types of information in various other ways. For example,
information concerning the environment in the vicinity of the
nozzle assembly can be received. That information can be conveyed
to an appropriate location in a desired fashion. For example, the
boot 40 can be equipped with a smoke sensor, a temperature sensor,
or other suitable sensing means (not shown). In the event that
those sensors become activated, for example, by the presence of
smoke or fire, an alarm positioned within the boot can sound and/or
a distress signal can be transmitted to a remote location. The
alarm system can be adapted to use the speaker of the system to
convey an audio alarm.
[0069] Referring to FIG. 7, boot 40 includes a pad that is adapted
to conduct a survey. A selection system, such as keys 146, can be
pressed to enter an answer or opinion associated with that key. In
one preferred embodiment, the question or statement that prompts
the user to respond can be conveyed as an audio message from a
speaker located within the nozzle assembly. In this regard, the
information entered can be used to gather demographics, consumer
preferences, conduct surveys, satisfy placed orders, and the like.
The information so provided by the customer can be stored within
the communication system of the nozzle assembly for collection and
processing at a later time. Alternatively, the information provided
by the customer can be conveyed to a remote location for
processing. A clock or other timing mechanism located within the
communication system can allow the station or store operator to
relate the survey response to a date and time. Gathered data can be
collected and processed using the general types of techniques set
forth in U.S. Pat. No. 5,724,521 to Dedrick; U.S. Pat. No.
5,732,218 to Bland et al.; U.S. Pat. No. 5,794,210 to Goldhaber et
al. and U.S. Pat. No. 5,794,207 to Walker et al.
[0070] Referring to FIG. 8, there is shown partially in phantom) a
top view of a portion of the nozzle assembly. Boot 40 includes a
pad 66 that is adapted to dispense a coupon 160. That is, within
the housing 45 of boot 40 is positioned coupon dispensing system
163. The coupon dispensing system 163 can be used to provide a
customer with an award associated with the playing of a game of the
type previously described with reference to FIG. 5. As such, the
integrated circuitry employed for the previously described game
systems can be incorporated into the housing 45 of the boot, and
the previously described game faces can be positioned on the top
region of the boot, above the coupon dispensing system.
[0071] A representative coupon dispensing system 163 includes a
coupon printer 166 and roller 169 carrying a long strip of material
172, such as paper, for coupons, or carrying a series of coupons
connected together at a series of perforation points or score
lines. The perforation lines or score lines extend generally
perpendicular to the longitudinal axis of the paper strip. The
roller 169 is situated within a delivery mechanism 175 that
includes stanchions 180, 182 for supporting the roller. The strip
paper 172 passes through a coupon printer 190. The printed coupon
160 then exits the dispensing system 163 in delivery region 195.
The coupon 160 can be torn off along a line of perforations, along
a score line, or torn off along the edge of the dispensing system.
Suitable printers and drivers are available commercially, for uses
such as at pay-at-the-pump establishments. An exemplary type of
printing mechanism is available as Model CP 205 MRS from Advanced
Printing Systems. Other suitable printing mechanisms are available
from Datamax Corp. and Addmaster Corp.
[0072] Another representative coupon dispensing system 163 can
include a roller 169 carrying a strip of paper 172. The strip of
paper can have a series of perforation points or score lines
separating a series of pre-printed coupons 160. Such a system 163
does not require a printer. In use, the coupon is dispensed from
the system by a controlled turning of the roller at a predetermined
time for a predetermined period of time. As such, the paper is
rolled off of the roller in order that the coupon extends from the
dispensing system. The turning of the roller is accomplished using
an appropriate mechanical paper feeding mechanism controlled by a
microprocessor that is a component of the communication system 48.
Such a system is particularly desirable for delivering coupons made
from paper, thin plastic, laminated paper/foil materials or
laminated plastic/foil materials.
[0073] Referring to FIG. 9, the boot 40 possesses the roller 169
carrying a roll of paper 172. The delivery mechanism 175 of the
coupon dispensing system 163 is shown. The integrated circuitry,
power source, and other relevant components are not shown. The
coupon can be dispensed from one side of the nozzle assembly, or if
desired, the system can be arranged in order that the coupons are
delivered in a different manner. For example, the coupons can be
dispensed from another location (e.g., the top, front or back face)
of the nozzle assembly.
[0074] In an alternate but less preferred embodiment, a stack of
individual pre-printed coupons can be positioned within a storage
region of the coupon delivery system within the nozzle assembly.
Each coupon the can be dealt from the delivery system using a
suitable delivery mechanism controlled by a microprocessor.
[0075] Components used to provide delivery of the coupon can
include a variety of electronic and mechanical components, and
those types of components can be readily adapted from the types of
coupon delivery systems that have been developed for numerous other
applications. There are numerous known systems, including the
mechanical components and electronic controls, for delivering
receipts and coupons; and the components of the present invention
can be readily adapted from those types of designs, components,
materials and technologies. For example, the general types of
components suitable for delivering coupons can be based on those
designs, components and technologies used to deliver receipts at
automatic bank teller machines, receipts for pay at the pump
gasoline purchases, and next in line numbers for customers at the
service counters of grocery stores.
[0076] The coupons that are delivered from the nozzle assembly can
serve a variety of purposes. Coupons can be dispensed as receipts.
Coupons can be provided as collectible or novelty items for
customers to save. Coupons can be provided as game pieces for a
promotional game sponsored by the proprietor of the convenience
store or gasoline station associated with the pump (e.g., each
coupon can have the form of a card for a card game or a piece of a
puzzle, and the consumer is encouraged to return on numerous
occasions to collect a winning hand or solve the puzzle). Coupons
can provide a customer with a reason or incentive to return to a
particular convenience store or service station at a later date.
For example, each coupon can be used to provide a customer with an
opportunity to collect bonus points that can be redeemed for an
award. Coupons can provide a customer with reason to enter the
convenience store or service station in response to an incentive,
such as to claim a prize or to receive a discount on an item.
[0077] Referring to FIG. 10, there is shown a top view of a portion
of the nozzle assembly, and within housing 45 of boot 40 is
positioned a illuminated visual message board 196, such as a pad 66
that is adapted to possess an illuminated region that provides a
message. The viewing face 64 is covered by a transparent shield 68.
The message board is held in place and protected by a suitable
positioning mechanism 198. The positioning mechanism preferably is
produced from a plastic material, and is adapted so as to provide
snug positioning of the message board. The information supplied by
the message board 196 can be news, weather, sports, local traffic
conditions, current date and time, current temperature, current air
quality conditions, current atmospheric conditions, and the like.
The information can be received from a remote source and
transmitted to the boot 40 for retransmission to the user.
Alternatively, the information is generated by appropriate devices
(e.g., a thermometer or a clock) positioned within the nozzle
assembly. The illuminated region can be configured so as to flash
on and off, such as when the fueling system is ready to dispense
fuel or when the dispensing of fuel is complete. Such information
can be provided from a suitable connection to a computer network
system. The nozzle assembly also can comprise components for
delivering an audio message.
[0078] Referring to FIGS. 11 and 12, boot 40 includes a board that
is adapted to convey a message. That is, within the housing 45 of
boot 40 is positioned liquid crystal system, or other suitable
means for providing a graphic display 196. The system has a
transparent protective cover 68, in order that the message on the
graphic display 196 can be readily viewed. If desired, option
backlighting can be provided by a series of lights 70 powered by
power source 84. The lights 70 can be positioned so as to provide
back, edge, side or perimeter lighting. The system can provide
alpha-numeric information, but most preferably, the system provides
display of pictures, symbols, and the like, as well as movable
objects. An exemplary LCD is available as Model No. F02020 from
Purdy Electronics Corporation.
[0079] The illumination system most preferably is employed in
conjunction with at least one other feature, such as an audio
system, a game system and/or a coupon system (not shown). For
example, a game system can include illuminated lights, audio and
video systems can be synchronized in order to provide an effective
medium for conveying both audio and video messages, or selection
buttons associated with survey choices can illuminated.
Alternatively, a thermometer positioned within the nozzle assembly
can sense environmental conditions, and the current temperature can
be displayed on an illuminated on a screen on the nozzle assembly
and conveyed as an audio message through the speaker associated
with the nozzle assembly. Flashing lights and a warning sound
emitted through the speaker can provide an effective warning
message to the user.
[0080] Referring to FIG. 13, a vehicular nozzle assembly 3 includes
a nozzle with frame 10 and spout 31. The nozzle assembly is of
essentially standard design and has a modular cartridge 199 and
associated components attached thereto. The cartridge 199 is
mounted at the forward top face of the nozzle frame 10, adjacent to
the spout 31 portion of the nozzle assembly. The cartridge 199
contains the various added features and components (and
combinations thereof) that have been described hereinbefore with
reference to the boots of the present invention. The nozzle frame
10 may be designed in order that the cartridge can be configured so
as to fit in a customized location therewithin. Alternatively, the
cartridge can be designed to be fitted to the nozzle frame, and to
be attached to that frame by adhesive, screws, clamps, or other
suitable fastening means.
[0081] Referring to FIG. 14, a nozzle assembly 3 includes a nozzle
with frame 10 and spout 31. The nozzle assembly is of essentially
standard design and has a modular cartridge 199 and associated
components mounted on the hose 1s. The cartridge 199 is positioned
on the hose immediately adjacent the back nozzle so as to be
viewable and usable when the user is handling the nozzle assembly.
The cartridge 199 contains the various added features and
components (and combinations thereof) that have been described
hereinbefore with reference to the boots of the present invention.
The pad is secured (e.g., with a clamp or a belt) to the hose using
a securable band 200, that can be manufactured from metal, fabric,
plastic, or the like.
[0082] The nozzle assemblies of the present invention can be
designed in order that the aforementioned components can be
incorporated as a component part of that assembly. As such, a
nozzle assembly can be customized in order to have a housing or
compartment that is designed to act as a housing for various of the
communication components 54 that provide the various features of
the present invention. As such, the nozzle assembly 3 can have
those various components incorporated as integral components
thereof. The specific design details relating to such a nozzle
assembly will be a matter of choice. In addition, the selection of
components, configuration of components, and overall adaptation of
components for the aforementioned nozzle assemblies can be based on
the teachings of U.S. Pat. No. 5,184,309 to Simpson et al., U.S.
Pat. No. 5,365,984 to Simpson et al. and U.S. Pat. No. 5,458,170 to
Ferguson, which are incorporated herein by reference.
[0083] The foregoing embodiments preferably incorporate electronic
circuitry of the type shown schematically in FIG. 15. In
particular, the communication components 54 include the
representative circuit that comprises a power source 84, a
switching mechanism 78 (e.g., a position sensitive mercury switch),
a regulator 203, voltage monitor 206, a microcontroller 210 and
various communication components. The operations of the various
communication components are controlled by the microcontroller. An
audio system can comprise an audio processor 218, an audio
amplifier 220, a speaker 56 and an automatic gain control 224. A
microphone 230 can receive an audio signal, and the signal can be
stored by the audio processor 218 or transmitted from transceiver
232 to a remote location. The microcontroller 210 also can control
the activation, deactivation and operation of the coupon delivery
system 240. A key pad 250 can provide for entry of information
(e.g., such as in the conducting of a survey) for storage and
transmission by microcontroller 210 and the transceiver 232. A
survey system that collects information entered by key pad 250 can
store or otherwise save information using the microcontroller 210
and a suitable storage device 254. Illumination preferably is
provided on a graphic display system 70. Software for games can be
programmed into the microcontroller 210.
[0084] A representative storage device 254 is an electrically
erasable programmable read only memory (EEPROM) device that
provides for storage of digital data. Such digital data may be
stored, (i.e., written) to the device 254, and retrieved (i.e.,
read) from the device by the microcontroller or microprocessor 210.
A suitable data storage device is Part No. 93LC46 form Microchip.
Other exemplary devices include National Semiconductor Part Nos.
NM93C06, NM93C46 and NM93C56; and Microchip Part Nos. 93LC46A and
93LC56.
[0085] The power source most preferably includes a battery 84, a
regulator 203 and a battery monitor 206. Batteries supply power to
the regulator, which in turn regulates the voltage that is supplied
to all or most of the electronic components, including the selected
chips that compose the integrated circuit. The battery voltage
level is monitored by a monitor chip 206, such as Maxim No. MAX
809. At a predetermined voltage, the monitor chip sends an
interrupt signal to the microcontroller 210, which then takes
appropriate action as dictated by program code. For example, the
action can cause stoppage of all system activity to conserve
battery power.
[0086] A regulator 203 is an electronic device that automatically
holds a quantity, such as voltage or current, to a constant value.
For example, electrical input of a particular voltage supplied by a
power source (e.g., a battery, power supply or another regulator)
84 is then converted to a specific different desired voltage and
supplied to the output of the regulator 203. The output voltage, in
turn, provides this desired voltage to other systems or electrical
devices within the circuit. Exemplary regulators are available as
National Semiconductor LM317, LM341 and LM1578; Linear Technologies
LT1129, LT1170 and LT1121; and Maxim Integrated Products MAX 1684,
MAX 1685 and MAX 1623. A preferred regulator is available as Linear
Technologies LT 1129.
[0087] A microcontroller 210 is a highly integrated single-chip
microcomputer. Some of the key elements of a microcontroller
include a central processing unit (CPU) to process information,
program memory to store instructions, data memory to store
information, system timing, real timing and input/output sections
for communication. Preferred microcontrollers contain real time
clocks 255. The microcontroller and the programming thereof can
vary. Exemplary devices include those types of microcontrollers
selected from the National Semiconductor COP8 series, the Microchip
PIC12 series, the Zilog Z8 and Z8 Plus series and Motorola M68HC11.
Preferred microcontrollers are the National Semiconductor COP8
series devices, and information concerning those types of devices
can be found in Nation Semiconductors, COP8 Microcontroller Data
Book 1996/1997 edition.
[0088] A preferred audio processor 218 is available as ISD
Voicecorder IC from Information Storage Devices Inc. Such an audio
processor employs a storage technique called digital analog storage
technology (DAST). Such an audio processor stores audio
information. Serial communication lines on the processor allow the
microcontroller 210 to send commands to that processor 218 (e.g.,
play, record, stop, fast forward, and the like). During the record
cycle, audio information is applied to the audio input of the
processor 218. This audio information may be from a microphone via
the AGC circuit 224 or other external sources such as a computer,
compact disk player, equalizer, or the like. The AGC circuit 224
adjusts the audio input level to the required level of the
processor. Within the audio processor, the audio information is
conditioned and sampled at some sampling rate. Each sample result
is then stored in an on-chip nonvolatile memory array with the
audio processor. During the play cycle, the stored audio
information is passed through filters and smoothed, and then output
from the processor to an audio amplifier 256, which boosts the
signal to levels required to drive the speaker 56. Many audio
amplifiers 256 are available from several manufacturers. Exemplary
devices include National Semiconductor Part Nos. LM4860 and LM4861;
and Motorola Part Nos. MC13060 and MC34119.
[0089] An alternate audio system can make use a voice-band audio
processor (VBAP). During record, the VBAP device receives audio
information in the same manner as the previously described audio
processor 218. Inside the VBAP device, the audio signal is passed
through filters and an antialiasing circuit, and then to an analog
to digital converter (A/D). The resultant data, under control of
the microcontroller 210, is clocked out of the device and stored in
memory 254, such as EEPROM or non-volatile random access memory
(NVRAM ). During play, the microcontroller shifts the desired
stored data from the memory 254 to the data in pin (DIN) of the
VBAP. The data is passed through a digital to analog converter
(D/A), and then through switched capacitor filters, which condition
and smooth the signal. The signal then is passed through an
amplifier within the VBAP, and output the data out pin (DOUT). This
signal is then passed to the audio amplifier 220 to be amplified to
a level needed for the speaker 56. An exemplary VBAP is Texas
Instrument Part No. TCM320AC36.
[0090] The visual display system 70 can vary. Numerous visual
display systems are available, and the exact selection can be a
matter of choice. Criteria used in the selection of the visual
display system include cost, durability, and the like. A typical
visual display system includes a LCD display 260 and a LCD display
driver 196. An exemplary visual display system is a FE0202 LCD
display manufactured by Purdy Electronics Corp. An exemplary driver
is a Maxim IMC7211. The driver 196 decodes data and conditions
signals for the LCD display 260, as well as reduces the workload on
the microcontroller 210. In operation, each letter, number or
graphic character is designated a specific code. When it is desired
to display one of those characters, the microcontroller via
communication lines passes the associated code to the display
driver. The microcontroller passes another code to the display
driver, informing the driver of the location of the character on
the display. The display driver then decodes this information and
activates the appropriate pins on the LCD display. The graphic
display system 70 also can include a touch screen display 261.
[0091] Input and output of information can be provided in a variety
of ways. Serial data as it pertains to electronic applications,
pertains to the performance of steps, or the occurrence of
elements, (e.g., data items) in succession, and an order, row, or
sequence in which one item follows another. There are a multitude
of methods available to accomplish the transmission and reception
of serial data. The most common method utilizes a universal
asynchronous receiver/transmitter (UART). The UART receives and
transmits information from a microcontroller 210, and transfers
that information to and from a remote device (i.e., a device being
removed or not a component of the microprocessor). Many
microprocessors contain a UART as do some of the National
Semiconductor COP8 series components. Signals can be conditioned in
a way to protect or isolate the devices in communication with each
other. Several standards have been developed to define the
protection method of serial data exchange, and those include
RS232C, RS422 and RS485. An example of a UART/RS232 transceiver
that is directly compatible with most microcontrollers is the Maxim
MAX3110E; which is a UART combined with an RS232 transceiver. Most
higher end microprocessors will have at least one UART built into
those devices; and in such a case, all that is needed is an
appropriate transceiver such as RS232, RS422 or RS485. Serial ports
264, 265 can communicate information with another compatible
electronic devices 266.
[0092] Parallel communication pertains to the type of operation in
a logical electronic system when all elements in an information
item (e.g., bits in a word) are acted upon simultaneously rather
than serially. Parallel ports 268, 269 are ports that provide
communication to external devices 270. The parallel ports operate
under the IEEE 1284 "Standard Signaling Method for a Bi-directional
Parallel Peripheral Interface for Personal Computers" standard.
Microcontrollers can utilize one or a combination of many available
parallel communication chips 268, 269 to provide communication with
external devices 270. One such parallel communication chip is the
Fairchild Semiconductor 74LVX161284 Low Voltage IEEE 161284
Translating Transceiver.
[0093] The transceiver 232 can provide effective bi-directional
transfer of wireless information. Many methods are available to
accomplish wireless transmission of information . Application,
distance, environment, available frequency bandwidth and system
configuration are just a few criteria which determine the best
choice. Exemplary types of transcivers are the LINX Technologies SC
Series RF Transceivers. These transceivers have the ability to
transmit and receive digital or audio information in the vicinity
of 916 Mhz. The UART compatible output of these transceivers 232
provides easy interface with the microcontroller 210. Information
selected to be transmitted is directed by the microcontroller. The
information can be audio in form from the microphone 230 and AGC
224, previously stored audio information from the audio processor
218, or digital data directly from the microcontroller (which has
access to virtually all information in the system).
[0094] The purpose of the antenna 275 is to radiate and absorb
electromagnetic waves in a selected frequency range. Antenna
selection is dictated by the transceiver 232 selection. For
instance, the LINX SPLATCH Planar Antenna No. ANT916-SP can be used
with the previously described transceiver.
[0095] The purpose of the camera system 277 is to convert a visual
image to representative electronic signals. This is not limited to
the human visible spectrum. Many chipsets or complete modules are
available to accomplish this. The microcontroller can determine how
this information is utilized as in stored, transmitted and so
forth. An exemplary camera system is a Sony CXD2463R Timing
Controller 278 with the Sony CXA1310AQ Single Chip Processor 279
combined with the Sony ICX404AL Image Sensor 280. This forms a
complete system to serve the purpose. The desired image qualities
(e.g., black and white, color, resolution, signal format, and the
like) needed in a particular system configuration will dictate the
choice in available cameras or camera systems.
[0096] Referring to FIG. 16, there is shown a representative nozzle
assembly 3 of the present invention. The nozzle assembly includes a
standard fuel dispensing nozzle 6 including a frame 10, and a
connector 12 to a hose 15 from a pump (not shown), in order that
fuel from the pump can pass from the pump through the hose to
within regions of the nozzle frame. The nozzle assembly 3 includes
a handle region 20 that is adapted in order that anyone using the
nozzle assembly can readily grasp that assembly. The assembly also
includes a hand guard 43, trigger 25 or other suitable means for
controlling the flow of fuel through the assembly, as well as an
optional manually operated control lever 28 (e.g., a hold-open
latch) that is in mechanical communication with a shut off
apparatus within the nozzle frame. A generally tubular spout 31
provides a means for directing the dispensing of fuel to the
desired location. An optional wound wire 35 around the spout 31
provides a simple way to maintain positioning of the spout within a
fuel receptacle (not shown). Most preferably, the frame, spout,
handle, trigger, hand guard and numerous internal components are
manufactured primarily from plastic materials.
[0097] The nozzle assembly 3 can be constructed from two components
(i.e., a right hand side and a left hand side) that combine to form
a nozzle assembly of the present invention. The two components (not
shown) can be combined together to form the nozzle assembly, and
those components are fixedly secured together using a suitable
adhesive, screws, clamps, or other suitable securing means. The
various fasteners can be constructed from metal or plastic
materials. Although not shown, the component parts also can include
positioning bosses, stabilizing ribs, and the like; and such
features are provided in order to facilitate production and
assembly of the nozzle assembly, as well as provide integrity and
other desirable physical characteristics to the nozzle
assembly.
[0098] The nozzle assembly 3 includes a spout portion 31, such as a
coaxial spout that possesses an inner liquid pathway, and for the
most preferred embodiment, an outer vapor pathway (not shown). The
preferred assembly also includes a thermoplastic hand guard, and a
thermoplastic outer body. The nozzle assembly of the type described
with reference to FIG. 16 can be designed and constructed to meet
the properties, performance and specifications required for
C.A.R.B. approval and U.L. listing.
[0099] The nozzle assembly 3 has a size that can be comparable to
that of conventional nozzle assemblies. Typical dimensions are
about 12 inches to about 15 inches in total length, about 2 inches
to about 3 inches in maximum width, and about 8 inches to about 12
inches in total height. The spout assembly has dimensions that can
vary. Typically, the spout dimensions are suitable for delivery of
unleaded gasoline into the filling region of the gasoline tank of
an automobile. The dimensions of the various other components of
the nozzle assembly of the present invention can vary. However, the
dimensions and overall design parameters are generally comparable
to many of those dimensions and parameters of nozzle assemblies
that have been employed in traditional commercial applications.
[0100] The nozzle assembly 3 most preferably is rendered capable of
conducting electricity to some degree. In a preferred embodiment,
the plastic material employed in the manufacture of at least some
components of the nozzle assembly can be rendered capable of
conducting electricity. Specifically, it is desirable for the
nozzle assembly to provide for conduction of electricity in order
that any build up of static electricity can be grounded through the
nozzle assembly and through the hose to ground. The manner in which
the nozzle assembly is designed so as to provide suitable
electrical conductivity can vary, and the nozzle can be equipped
with a variety of electrical conducting means. Typically,
electrically conductive material can be dispersed within the
plastic material. Such a type of material can vary. Such a material
can be metallic particles, graphite fibers, or the like. An example
of a suitable plastic material in Norel, which is manufactured by
General Electric Corporation. If desired, an optional conductive
strip, fashioned wire, braid, mesh, or the like (not shown) can
extend through the inner regions of the nozzle assembly. That
conductive material can extend throughout the length of the nozzle
assembly so as to alleviate static electricity build up within the
automobile by providing for conduction of electricity through the
nozzle and hose to ground. Alternatively, the conductive material
can have the form of a rod, or other form of a plastic material
that is electrically conductive.
[0101] The spout 3 1of the nozzle assembly 3 can be designed so as
to be integral to the remainder of the nozzle assembly.
Alternatively, the spout portion can be provided as a separate
piece that can be fixedly secured to the remainder of the nozzle
assembly. For example, the spout can possess a threaded region at
one end, and that threaded region can be secured in place by way of
a corresponding threaded region of one end of the nozzle assembly.
The spout portion also can be secured in place using a suitable
adhesive. Suitable manners for securing the spout portion to the
remainder of the nozzle assembly are known. For example, the spout
portion can be adapted so as to be secured to the remainder of the
nozzle assembly in the manner set forth in U.S. Pat. No. 4,682,714
to Wood. Most preferably, the spout is manufactured primarily from
a plastic material.
[0102] A nozzle assembly 3 is connected to the hose 15 of the
dispensing system. This typically is provided by connection to a
connector 12, metal swivel assembly, or other suitable connection
means, which provides for connection to the hose. Normally, the
nozzle assembly possesses a threaded region at the end opposite the
spout, and that threaded region is fixedly secured in place by way
of a corresponding threaded region of the metal swivel assembly.
Connection mechanisms also can possess breakaway mechanisms (not
shown). See, for example, U.S. Pat. No. 4,615,547 to Sutcliffe et
al; U.S. Pat. No. 4,667,883 to Fink, Jr.; U.S. Pat. No. 4,827,977
to Fink, Jr. and U.S. Pat. No. 4,828,183 to Fink, Jr. Various types
of connection mechanisms are commercially available. For example,
representative connection mechanisms, swivels and the like are
available from Emco Wheaton Retail Corporation, Catlow Incorporated
and Husky Corporation.
[0103] If desired, nozzle assembly 3 is equipped with an additive
cartridge. For example, the top region of the nozzle assembly can
designed so as to possess at least one slot or other housing
mechanism by which the suitably designed cartridge (not shown) can
snap in place (or otherwise fit by friction fit, or the like) so as
to be secured in place. If desired a locking strap can be used to
maintain those optional components in place relative to one
another. The various optional components have been described
previously with reference to the other aspects of the present
invention.
[0104] The assembled nozzle assembly 3 is designed so as to be
capable of providing adequate fuel delivery. Typical preferred
assemblies are capable of providing delivery of about 6 to about
14, generally about 8 to about 12, and frequently about 10 gallons
of fuel per minute.
[0105] The nozzle assembly most preferably is equipped with a flow
control valve (not shown), or other suitable means for controlling
the flow of fuel through the nozzle. Representative flow control
valve mechanisms and designs are set forth in U.S. Pat. No.
4,343,337 to Healy; U.S. Pat. No. 4,453,578 to Wilder; U.S. Pat.
No. 4,809,753 to Fink, Jr.; U.S. Pat. No. 4,825,916 to Fink, Jr.;
U.S. Pat. No. 4,658,987 to Fink, Jr.; and U.S. Pat. No. 5,007,468
to Wilder et al. The nozzle assembly also can possess a shut-off
mechanism (not shown), such as a pressure-activated system of the
type set forth in U.S. Pat. No. 5,992,479 to Simpson.
[0106] The various connectors, control mechanisms, valves, and the
like, that. traditionally are used in the construction of nozzle
assemblies can be incorporated into nozzle assemblies incorporating
parts or components composed primarily of plastic materials.
Certain components, such as springs, clamps, valve mechanisms, and
the like can be standard components that are manufactured from
metallic materials. However, certain of those standard components
can be designed or adapted so as to be manufactured from plastic
materials. Certain passageways, valve components, component
housings, connectors, fasteners, and the like, can be fashioned
from plastic materials.
[0107] Nozzle assemblies constructed using plastic materials have
several advantages. The nozzle assemblies are relatively easy to
assemble, and construction is less labor intensive, because of the
reduced number of parts. The various components can be manufactured
efficiently and effectively using relatively low cost materials.
Many components can be designed so as to incorporate many of the
features or component parts of traditional nozzle assemblies. In
addition, the nozzle assembly components can be designed to
incorporate certain known components or to be compatible with
certain known components. As such, the number of component parts
can be consolidated into a significantly fewer number of component
parts.
[0108] The nozzle assembly 3 can be equipped so as to minimize the
amount of fuel vapors that escape into the atmosphere during use.
For example, the nozzle assembly can possesses a series of tubular
passages longitudinally therethrough. Representative vapor recovery
systems are set forth in U.S. Pat. No. 4,057,086 to Healy; U.S.
Pat. No. 4,095,626 to Healy; U.S. Pat. No. 4,336,830 to Healy; U.S.
Pat. No. 4,566,504 to Furrow et al. and U.S. Pat. No. 5,197,523 to
Fink, Jr. et al. U.S. Pat. No. 5,327,944 to Healy. The nozzle
assembly can be equipped with a vacuum assist vapor recovery system
of the type set forth in U.S. Pat. No. 4,429,725 to Walker et al.
The nozzle assembly can be equipped with a bellows assembly; such
as is set forth in U.S. Pat. No. 4,056,131 to Healy; U.S. Pat. No.
4,343,337 to Healy; U.S. Pat. No. 5,085,258 to Fink, Jr. et al.
Typical bellows assemblies are manufactured from polyurethane
materials. Alternatively, the nozzle assembly can be equipped with
a plastic guard; such as the type set forth in U.S. Pat. No.
4,010,781 to Sutcliffe.
[0109] The components of nozzle assemblies of the type described
with reference to FIG. 16 incorporate plastic materials, and it is
most preferred that the majority of the components be manufactured
from materials consisting primarily of plastic materials.
Components of nozzle assemblies composed primarily of plastic
materials are such that the majority of the volume of the relevant
components is provided by plastic material. By "plastic material"
is meant a primarily organic material that is synthetically
produced and can be formed into the desired shape. The manner by
which the components are manufactured from a plastic material can
vary. Preferred plastic materials are those that can be injection
molded or thermoformed into the desired shape. Preferred plastic
materials incorporate thermoplastic polymer materials. Thermoset
polymers, such as vinyl ester resins, bisphenol A based epoxy
resins, isocyanate based polymers, diisocyanate based polymers,
also can be employed. Reaction injection moldable plastics, such as
polyurethanes, also can be employed. In addition, plastic materials
can be bulk molded, sheet molded, thin wall thermoformed or
prepegged.
[0110] Plastic materials are used in outer components, inner
components and spout. Typically, the component parts or pieces are
injection molded. Components also can be blow molded, particularly
for those components that have a one piece construction.
[0111] The specific formulation and specific components of the
plastic material can vary. Suitable types of thermoplastic
materials are those employed for the manufacture of those
thermoplastic outer body nozzle assemblies that are available as
Saber 1.0, Flow and Saber 1.5, Display from Saber Equipment Corp.
Suitable plastic materials also include those nylon materials
(e.g., Super Tough Nylon) that are employed in the construction of
lever and hand guard portions of the NE Elite Automatic Nozzle, the
Inverted Vapor Recovery Nozzle and the Elite Pre-Pay Nozzle
(available from Catlow, Inc.).
[0112] Exemplary plastic materials include polycarbonates, such as
Lexan, which is available from General Electric Corp. Another
representative plastic material incorporates an amorphous polymer
exhibiting crystalline properties, such as is available as Isoplast
(e.g., Isoplast 101, Isoplast 301, Isoplast 40 percent glass and
Isoplast 60 percent glass) from The Dow Chemical Company. Another
representative amorphous plastic material is a styrene
acrylonitrile plastic available as Tyril (e.g., Tyril 880 and Tyril
1011) from The Dow Chemical Company. Another representative plastic
material incorporates thermoplastic semi-crystalline polymers, such
as the polybutylene terephalates available as Valox (e.g., Valox
310, Valox 25 percent mineral and Valox 30 percent glass) from
General Electric Corp. and the polyphenylene sulphides available as
Supec (e.g., Supec 30 percent glass) from General Electric Corp.
Exemplary plastic materials also can be blends of plastics; and
representative plastic materials can be blends of thermoplastics
that are characterized as amorphous and crystalline plastics.
Amorphous plastics, such as polycarbonate, provide impact
resistance to the plastic material; and crystalline plastics, such
as polybutylene terephalate, provide chemical resistance to the
plastic material. For example, a thermoplastic available as Xenoy
(e.g., Xenoy 1101, Xenoy 10 percent glass and Xenoy 30 percent
glass) and from General Electric Corp. is a blend of polycarbonate
and polybutylene terephalate. Suitable plastic materials also be
plastic alloys or blends, such as those that can have electrically
conductive plastic materials as components thereof. An example of a
suitable plastic material is Norel, which is manufactured by
General Electric Corp.
[0113] The components that are used to construct the nozzle
assembly 3 can include a wide variety of other materials. Those
other materials can include pigments, ignition inhibitors, ultra
violet inhibitors, filling compounds, reinforcing agents,
electricity conducting agents, and the like. For example, the
plastic materials can reinforced with glass fiber, graphite fiber,
metal filings, powdered minerals, mineral/glass mixtures, and the
like. Typically, such fillers can comprise up to about 60 percent,
but preferably less than 50 percent, of the total weight of the
resulting polymer material. Typically, optional components, such as
ultra violet radiation inhibitors, are present at relatively low
levels (e.g., less than about 5 percent of the overall weight of
those components used to provide the total composition of the
plastic nozzle assembly). Such other materials are employed in
order to provide a wide range of characteristics and properties to
the nozzle assembly. For example, those materials provide aesthetic
features to the nozzle as well as improve the physical, mechanical
and chemical resistance properties of the nozzle assembly under
that range of conditions experienced during normal use.
[0114] The components that are used to provide the nozzle assembly
3, and the design of the nozzle assembly, are such that the nozzle
exhibits desirable physical, mechanical and chemical properties
under normal conditions of use.
[0115] The components that are used to construct such a nozzle
assembly most preferably exhibit good resistance to petroleum-based
fluids. That is, the components are suitably resistant to
petroleum-based fuels and solvents under those conditions of normal
use of the nozzle. The components can experience contact with
petroleum-based fluids, such as gasoline, kerosene and diesel fuel,
without being dissolved or experiencing any adverse chemical
reaction to any significant degree. As such, as a result of the use
of the nozzle to deliver fuel to the desired container, the nozzle
does not experience any appreciable loss of integrity and the fuel
that is delivered is not undesirably contaminated. For example, it
is preferred that the nozzle assembly does not undergo an
undesirable discoloration due to repeated contact of the nozzle
assembly with petroleum-based fluid under normal conditions of use.
Typically, plastic materials possessing some degree of
crystallinity can possess relatively high degrees of chemical
resistance. Additive components can be incorporated into the
plastic material in order to enhance the chemical resistant
properties of the nozzle assembly components.
[0116] The components that are used to construct such a nozzle
assembly exhibit adequate strength and impact resistance in order
for the nozzle assembly to withstand conditions of normal use. The
components most preferably are tough and are not brittle. It is
desirable that pieces of the nozzle assembly are sufficiently hard
and of sufficient integrity so that portions thereof are not
readily chipped or scraped therefrom. Thus, it is desirable that
particulate impurities originating from the nozzle assembly not be
introduced into the fluid container, tank or reservoir. However, it
is also desirable to construct the nozzle from plastic materials,
or plastic materials containing additive materials, such that the
plastic material from which the nozzle is composed has a density of
greater than that of the fuel delivered thereby. As such, as
chipped or broken nozzle material that is accidentally introduced
into a fuel tank or reservoir will readily sink to the bottom of
that container.
[0117] The components that are used to construct such a nozzle
assembly are weatherable. That is, the components do not have a
tendency to craze or crack over extended periods of time. The
components that are used to construct the nozzle of the present
invention exhibit desirable properties over a wide range of
temperatures. The components preferably are resistant to melting
upon exposure to relatively high temperatures. The components
preferably exhibit good cold weather impact resistance.
[0118] The components that are used to construct such a nozzle
assembly most preferably exhibit good impact resistance. That is,
the components are suitably resistant to those physical and
mechanical stresses that the nozzle may experience under those
conditions of normal use. Typical preferred plastic materials have
a tensile strength of at least 7,000 psi, and more preferably at
least 8,500 psi; a flexural strength at least 9,000 psi, and more
preferably at least 12,000 psi; and a flexural modulus of at least
15,000 psi, and more preferably at least 20,000 psi. For example, a
suitable plastic material, available as Xenoy Grade 1731 from
General Electric Corp. exhibits a tensile strength of about 8,900
psi, a flexural strength of about 13,500 psi, a flexural modulus of
about 340,000 psi, a notched Izod impact of 12.5 ft-lb/in at
73.degree. F. and a notched Izod impact of 2 ft-lb/in at
-22.degree. F. As another example, a suitable plastic material,
available as Isoplast Grade 40% Glass exhibits a tensile strength
of about 27,000 psi, a flexural strength of about 45,000 psi, a
flexural modulus of about 1,500,000 psi, a notched Izod impact of 8
ft-lb/in at 73.degree. F. and a notched Izod impact of 8 ft-lb/in
at -40.degree. F.
[0119] The useful lifetime of such types of nozzle assemblies can
vary, depending upon factors such as environmental conditions,
degree of abusive treatment and frequency of use. Typically, a
nozzle of the present invention possesses a useful lifetime, under
conditions of normal use at a service station or convenience store,
of at least 1 month, and preferably of at least 3 months. The
nozzle assemblies can be manufactured efficiently and effectively
from low cost components. The nozzle assemblies, or components
thereof, can be readily replaced. Used nozzles, due to their simple
design and the preferred limited number of components, can be
readily recycled for further use. Such properties, make the nozzles
desirable from an economic standpoint; that is, the nozzles of the
present invention can be manufactured, maintained and replaced much
more economically that conventional nozzle assemblies.
[0120] Preferred nozzle assemblies constructed from thermoplastic
materials are relatively light in weight, and can weigh
significantly less than conventional nozzle assemblies. Typical
preferred nozzle assemblies, and that are designed for use at
service stations and convenience stores, weigh less than about 2.5
pounds, and most preferably less than 2 pounds. The unique spouts
of those nozzle assemblies have a propensity not to scratch or chip
the painted finish of automobiles, as do conventional metal nozzle
spouts. In addition, by suitable selection of the plastic material
and design of the nozzle assembly, the nozzle assemblies possess
the "break away" or "drive away" safety features of the type
described within U.S. Pat. No. 5,363,889 to Simpson et al.
[0121] The nozzle assembly 3, as well as other nozzle assemblies
such as those presently in commercial use, can be equipped with a
sensing gauge (not shown). Such a sensing gauge is provided to
detect proper ground (or lack of proper ground). As such, the user
of a dispensing system can be alerted that the system is adequately
grounded. Other safety devices, such as carbon monoxide monitors,
heat sensors, smoke detectors, and the like, can be incorporated
into the nozzle assembly. As such, certain environmental conditions
can be sensed, and appropriate audio or visual alarms can be
activated.
[0122] If desired, the nozzles assemblies of the type described
with reference to FIG. 16, can be equipped with further additive
features, such as those boot or placard assemblies that can provide
advertising, messages or other features. Representative additive
assemblies for fuel dispensing nozzles are set forth in U.S. Pat.
No. 4,465,209 to Wilder; U.S. Pat. No. 5,058,637 to Fell; U.S. Pat.
No. 5,458,170 to Ferguson; U.S. Pat. No. 5,806,217 to Alvern; U.S.
Pat. No. 5,810,063 to Alvern; U.S. Pat. No. 5,815,967 to Alvern;
U.S. Pat. No. 5,865,340 to Alvern; U.S. Pat. No. 5,862,617 to
Alvern; and U.S. Pat. No. 5,887,367 to Alvern. Of particular note
are the Fueling Talker electronic advertising boots that are fitted
onto the nozzles of gasoline dispensing systems by DirectCast
Network, LLC. Other advertising and display systems suitable for
use are set forth in U.S. Pat. No. 5,134,716 to Craig and U.S. Pat.
No. 5,642,484 to Harrison, III et al. In addition, such a nozzle
assembly can incorporate those types of features and components
described previously with reference to FIG. 1-15.
