Description
RELATED APPLICATIONS
[0001] This application is related to Provisional Application
6/375,038 filed Apr. 22, 2002 entitled Apparatus for Controlling
the Environment of a Parked Vehicle which is now pending.
BACKGROUND
[0002] Long haul truckers frequently spend the night in the cabs of
their trucks. In fact, many trucks are designed with sleeping
areas. This necessitates environmental control and specifically
heating and cooling. In order to provide this heating or cooling,
the truck drivers generally leave the trucks running overnight to
utilize the truck's heating or air conditioning system. The
cumulative pollution created by these vehicles running overnight is
very significant.
[0003] Further, although such trucks are in a position to receive
radio signals, they are frequently located in positions where
television signals are unavailable or weak and certainly no
telephone connections are available to the truck itself.
[0004] Providing these services to a parked truck involves
overcoming many practical and physical problems. Payment for these
services is a concern as well as physically fitting the equipment
needed to provide these services in a small space is problematic.
Protecting this equipment from the environment is also a
concern.
SUMMARY OF THE INVENTION
[0005] Thus, it is an object of the present invention to provide an
apparatus and method for controlling the inside environment of a
vehicle such as a truck, RV or other vehicle. More particularly, it
is an object of the present invention to not only provide heating
and air conditioning but other conveniences such as electricity,
phone hookups, computer hookups, videos such as for continuing
education instruction or entertainment and a variety of related
services, providing such services within a limited access space,
i.e., through the window of a truck or a small access door.
Further, additional services may be provided for the vehicle,
including the ability to watch television, the ability to
communicate and even the ability to pay for the services. These
additional services may be delivered through wires or with a
wireless system.
[0006] Further, the present invention protects the equipment from
the environment.
[0007] The objects and advantages of the present invention will be
further appreciated in light of the following detailed description

DETAILED DESCRIPTION
[0019] As shown in FIG. 1, the present invention is an apparatus 10
for controlling the internal environment of a vehicle such as a
truck 11 shown in a parking space 12. It includes an environmental
control (HVAC) unit 14 which is suspended above the ground on a
support 15 resting on posts 16. The apparatus further includes a
ventilation head 18 which as shown is attached to the passenger
side window 19 of the cab of a truck 20 using a template. The head
18 is connected to the HVAC unit 14 by coaxial conduit 22 which
runs from the head 18 to the HVAC unit 14 and by an electrical
cable 24 which again runs from the support alongside the coaxial
conduit 22 to the head and can be held in a sleeve connected to
conduit 22. This is attached to a breakaway connector 21 near
support 15.
[0020] The head 18 as shown in FIG. 1 is attached to the window 19
of a truck cab 20. However, it can also be attached at any location
to the truck provided there is a receptacle within the truck
adapted to support the ventilation head. FIGS. 9 and 10 show
embodiments in which the ventilation head 18 is attached to a side
wall 26 of the truck cab at the door 28 of the sleeper compartment
30 as is disclosed in more detail below.
[0021] Head 18 includes a body portion 32 and a cover 34 which
closes and seals the face 36 of the body portion 32. These are
attached by a hinge 31 which preferably can be adjusted to vary the
tension. As shown in FIG. 7, the body portion 32 includes an inner
housing portion 38 attached to an outer housing portion 42 with a
gasket 44 between the two. Attached to the outer housing 42 is a
circular handle 41 which is held onto the outer housing by first
and second bracket members 48, 52. The first bracket member 48
includes one low voltage connection 54 and two high voltage
connectors 56, 58 connectors. These are all preferably water tight
connectors. The bracket 48 includes a removable service cover 53.
The second bracket 52 includes an exterior GFI A/C outlet 62.
[0022] As shown in FIGS. 2 and 3, the inner housing 38 has an inner
wall 64 and an outer wall 66 with an annular passageway 68 there
between. An inner circular conduit 72 is supported by first, second
and third support members 74 which extend to the inner wall 64 of
the upper housing. Extended from this circular conduit 72 are upper
and lower walls 76, 78 and face 82 which supports first and second
A/C electrical outlets 84, 86. Fan 82 is a removable service cover.
Also as shown on face 82 are a phone connector 88 and an ethernet
connection 92.
[0023] Outer wall 66 has a lower stepped annular portion 94 which
is covered by gasket 44. An annular screen 98 is positioned to
cover the area 102 between the inner conduit 72 and the inner wall
64 of the inner housing. Area 102 is the return air flow passage
for the system as indicated by arrow 101.
[0024] Abutting the gasket 44 is the upper edge 104 of the outer
housing 42. The outer housing 32 includes circular wall 106 which
forms a conduit. Inside the conduit 106 of the lower housing is a
lesser diameter conduit 107 which attaches to the inner circular
wall 72 of the upper housing.
[0025] Extended from the conduit 106 is an annular extension 108
which leads to the outermost or exterior wall portion 112 having
edge 104. This provides an annular passage 114 which communicates
with the inner passage 68 of the inner housing 38. The outer
housing 42 further includes first and second handle receiving
members 116, 118 which each include semi-circular arcuate channels
122, 124. The ring shaped handle 41 is held within this groove by
brackets 48 and 52, each of which have handle recessive grooves
126, 128.
[0026] Extending up from the handle are first and second prongs
129, 130. Each prong includes an outwardly extended tab 132, 134
and an inwardly extended tab 136, 138. The first prong 129 further
includes a planar arcuate member 140 perpendicular to and welded to
the inside surface of the prong 129.
[0027] The first handle receiving member 116 further supports first
and second spring biased switches 142, 144. The first and second
spring biased switches include first and second flag-shaped probe
members 146, 148. (See FIGS. 11A-11C) These probe members are fixed
within the spring biased switches and are both biased in the
direction of arrow 150. The first probe 146 includes an extended
portion 152 and a lower enlarged portion 154. When the first spring
biased switch is extended, in other words in a non-compressed
state, it is positioned in slot 156 in arcuate member 140. This
prevents the handle 41 from rotating. When this switch 142 is
compressed, the enlarged portion 154 of the probe 146 will move
below the arcuate plate member 140 and allow the handle 41 to
rotate in the direction of arrow 158.
[0028] The probe 148 of the second spring biased switch 144 has an
extended portion 162 and an enlarged portion 164. The enlarged
portion 164 has a slot 166. Slot 166 will allow enlarged portion
164 to ride on the arcuate plate member 140 when the switch is in a
compressed state. When enlarged portion 164 is aligned with the
slot 156 in the arcuate plate 140, i.e., when the probe 148 moves
in the direction of arrow 150, the enlarged portion moves into slot
156 stopping further rotation of the handle 46.
[0029] When assembled, the prongs 129, 130 extend upwardly through
the outer housing into the inner housing with the tabs 132 and 134
extending through slots 172, 174 in the outer wall of the inner
housing. Tabs 136 and 138 in turn extend through slots 176, 178 in
the inner wall of the inner housing near its upper edge 180. These
prongs latch and unlatch the cover 34 and prevent the unit from
being removed when the cover 34 is open as is explained below.
[0030] The first handle cover 48 includes three electrical
connections which are adapted to receive three separate sets of
wires. The first set of wires connect through fitting 54 and are
low voltage wiring such as telephone connections, ethernet
connections, television or radio antenna for cable. The second and
third set attach via fitting 56, 58 and provide high voltage
electric. The electrical wires would run through the bracket 48
around the handle 41 into the annular passage 114 in the lower
housing through the inner passage of the upper housing to the
central shroud.
[0031] The head connects to the HVAC unit utilizing a coaxial
flexible duct 22. The outer wall 120 of the coaxial duct attaches
to the exterior surface 122 of the large conduit 106 of the outer
housing. The inner conduit 123 is attached to the lesser diameter
conduit 107 which itself is attached to the inner housing. The
ratio of the cross-sectional inner conduit to the outer conduit
should be about 1 to about 3.
[0032] The head 18 includes the cover 34 which is attached by hinge
120 to the upper housing 38. The head 18 is attached to the window
of a vehicle using a template or adapter 126 as shown in FIG. 1.
The use of an adaptor allows one head design to attach to any
vehicle window. This adaptor 126 has an opening 128 which mates
with the head 18 and an exterior configuration which mates with the
window opening providing a tight seal. Spring biased latches 125
hold the head in place.
[0033] The opening 128 through the adapter 126 includes upper and
lower cut out portions 132, 134 adapted to permit tabs 132 and 134
to pass through the adaptor. When this occurs, the first spring
biased switch 142 is compressed by the adapter, forcing the first
probe 146 below the arcuate plate 140 permitting the handle to
rotate. Rotation of the handle will cause the tabs 132, 134 to
rotate out of alignment with cut out portions 133, 135 where they
engage the adaptor holding it in position. The upper tabs rotate in
slots 176 and 178 within the inner wall of the inner housing moving
out of engagement with latch members 166 and 168 in the cover
permitting the cover to open.
[0034] Rotating handle 41 will align the slot in arcuate member 140
with the enlarged portion of probe 148. As the cover opens, the
probe 148 of the second spring biased switch moves in the direction
of arrow 150. At this point, the enlarged portion of the second
probe 148 rests in the slot 156 in the arcuate plate 140 member
preventing further rotation. This prevents the head from being
separated from the adaptor if the cover is opened. This protects
the head from the environment.
[0035] Likewise to remove the head from the template, the cover
must first be closed which will compress spring switch 144 allowing
the handle to rotate which will hold the cover in a closed position
as the head is removed from the template.
[0036] The cover includes a variety of different features including
a USB-port 182, a connector 184 for the truck computer, a credit
card reader 186, a touch pad display screen 188 and a plurality of
different dedicated buttons or switches used to control the unit
and to activate various features of the unit.
[0037] The controls on the cover activate and control the
functioning of the unit. Head 18 has a central processing unit (not
shown) which can be programmed to function as desired and to
provide all desired Internet communication and functions. Although
the particular configuration of the head can vary dramatically
depending upon the desired functions, the device as shown has a
variety of beneficial features.
[0038] For example, it includes a touch switch 190 which turns the
screen light on and off so that the head can remain open during the
night without illuminating the cab. It further includes an adjacent
LED 191 which will help the occupant locate the light on/off switch
in the dark. There is also a dedicated help button 194 which can
initiate step by step procedures for the functioning of the head.
There is also a menu button which basically takes one to the top
level of the menu. A dedicated thermostat button 196 activates the
screen to show the temperature and provide for increasing or
decreasing the temperature within the cab as well as activating or
deactivating the fan. Also switches 198 to active the web browser,
messaging systems, catalog-type shopping, and the like can be
included. Finally a checkout button can also be provided. Spring
switch 144 can also act as a check out switch. Thus when the head
is removed from the template, the unit is deactivated and the
customer is billed.
[0039] Further, the connection 184 for the truck's onboard computer
permits communication between the truck's computer and a central
diagnostic unit via the Internet or through telephone lines.
[0040] The window adapter can be positioned into the window of the
truck by simply lowering the window, placing the adapter in
position and raising the window until it is held tight by the upper
pressure of the window against the template. This is preferably
done before the ventilation head is attached to the adapter. The
ventilation head would then be placed in the opening in the
adapter. Since the adapter rests against the gasket, a relatively
air tight seal is formed.
[0041] The present invention includes many different optional
features which improve the overall function of the present
invention. As shown in FIG. 1, the device includes a breakaway
system at the HVAC support. Thus, if a truck driver inadvertently
drives away with the unit attached, the lines will break away at
the upper area and thus no live electrical wires will be at ground
level.
[0042] The electrical lines connect to a central switching unit.
The electricity to the head particularly the 110V is only activated
or provided once the unit is installed and activated (generally
using a credit card). This would obviously prevent theft of
electricity as well as providing an added safety feature. The unit
also shows a 220 v. outlet 208 designed to run the reefer unit of a
trailer. This also would be activated via the head unit.
[0043] Further, when the unit itself is disconnected and the head
closed, air can be recirculated through the inner tube and return
through the outer tube recirculating air within the hose to
maintain flexibility in extremely cold temperatures. It would also
potentially prevent introducing very cold air into the cab of a
truck initially. This can be activated either locally or through a
central server.
[0044] As shown in FIGS. 9 and 10, instead of attaching the present
unit to the window of a truck or vehicle, it can be attached to a
wall of a vehicle using a semi-permanent adapter. This adapter 200
is a rectangular unit which is generally bolted or generally fixed
to the side wall of the cab of the truck or cab of the vehicle. It
can also be formed at the factory. Adapter 200 includes a door 202
covering a round opening 204 which corresponds in size to the
exterior shape of the head 18. Thus, it acts just like an adapter
30. Instead of inserting the head 18 into the adapter which is in
the window, one simply opens the door 202 and inserts the head 18
into this opening 204 and the unit is operated in the same manner
as previously described.
[0045] The present invention has been described with respect to a
separate head unit which is permanently attached to an HVAC unit.
It is also within the scope of the present invention to permanently
mount the head within the truck such as through a side wall and
simply connect the head to the HVAC unit at the truck stop. Thus,
the air handling hoses and electrical connections would simply plug
into a permanently attached unit on the truck. Once the connections
were made, the truck driver could then activate the HVAC unit and
other options such as Internet connection, electricity to the
reefer unit in the same manner as described with the preferred
embodiment of the present invention. Further, with respect to all
communication systems, the present invention has been described
wherein the communication lines are hard wired into the head.
Obviously this can be conducted using wireless communications if
desired.
[0046] This has been a description of the present invention along
with the preferred method of practicing the invention. However, the
invention itself should only be defined by the appended claims
wherein
