Description
RELATED APPLICATION DATA
[0001] The present application is a divisional of U.S. patent
application Ser. No. 10/741,537 filed Dec. 19, 2003.
FIELD OF THE INVENTION
[0002] The present invention relates to a method of constructing a
barbeque grill and various barbeque grill features.
BACKGROUND OF THE INVENTION
[0003] Outdoor barbeque grill units are very popular and produced
in a variety of configurations. These units include the well known
brickette accepting type grill and gas or propane powered
units.
[0004] Commonly, these grill units are constructed to be self
contained, small and portable. The unit includes a stand which
supports a grill housing, such as a metal casing. The housing, in
turn, houses one or more burners and supporting racks. Generally,
the housing includes a lid which may be opened to provide access to
the interior, including the racks. The lid may be closed during
cooking to retain the heat in the housing. Often, these grill units
are mounted on wheels to allow the user to easily move the grill
when it is not in use.
[0005] In order to increase the functionality of these units, they
are offered with side burners, warming trays, storage areas and the
like. This, of course, increases the size and complexity of the
unit. This makes the units difficult to move and more difficult to
construct.
[0006] More commonly, homeowners now desire custom "islands" which
include grills and associated amenities. In some instances,
homeowners still desire that the unit be movable. More frequently,
homeowners desire that the unit be "built-in" or stationary. In
either event, these homeowners generally desire that their grill
have the appearance that the grill is more of a furnishing or
structure, rather than a stand-alone appliance.
[0007] Various parties have sought to meet the needs of these
homeowners. Instead of mounting grills upon simple legs or a stand,
grills are mounted to cabinet structures. Generally, these cabinet
structures comprise a framed box upon which the grill and
associated components are mounted, the framed box also providing
for interior storage space. There are several problems with this
approach. First, these grill units are generally mass produced,
each having the same configuration and dimensions. This does not
allow a homeowner to request a "custom" unit having either specific
features or a specific configuration or size. Second, various
constraints limits the size of these units. In particular, these
units can not be very large because they must be transported to the
homeowner and installed at their home. The size and weight of the
unit must be constrained to permit transport of the unit, including
its passage through doorways and other structures and the home.
[0008] In other instances, the barbeque grill island or cabinet
structure may be constructed where it is intended to be used.
Generally, this entails the building of a wood frame structure,
application of an outer finish, and installation of grill elements.
This has the significant disadvantage that each unit must be custom
created, greatly increasing the time and cost of the unit as
compared to where the unit is pre-constructed only in a few
configurations.
[0009] In addition, whether of the pre-constructed or
custom-constructed configuration, these structures all suffer from
a number of drawbacks. For example, a homeowner desiring a
particular grill configuration can not see that configuration
before it is created. Instead, the homeowner must communicate their
desires to the builder and then wait and hope that the finished
product, after being custom created, appears as desired.
[0010] Besides the supporting island or cabinet structure these
types of grill, present grills suffer from a number of other
problems. One problem relates to grill handles. As indicated,
barbeque grills include lid which may be opened and closed. Because
the lid is part of the grill housing, it becomes very hot during
grill use. One or more handles are generally connected to the lid
for use in opening and closing the lid.
[0011] Commonly, the handle is made of wood. A wood handle has the
advantage that is does not transmit heat readily, allowing it to be
gripped by a user even when the grill lid is very hot. A problem
with such handles, however, is that if exposed to the weather, as
is common for outdoor grills, the handle will weather and
deteriorate. To avoid this problem, may grills are constructed with
a metal handle. However, these handles often become too hot to
touch, especially with newer grills having multiple burners and
higher heat.
[0012] Another problem relates to grill burners. It is desired that
the grill burner distribute heat and flame evenly over a large
area. As grills and their associated burners have become larger,
this goal has not been met with current burner configurations.
Generally, the length of these burners is such that the gas
pressure at areas close to the source is much higher than areas
remote from the source, causing the generation of much higher flame
and heat in one area than the other.
[0013] Many grills now include warming trays. These trays are
platforms which may be located towards the top of the interior of
the grill. Food items which a user desires to warm, rather than
cook, may be located on the tray. These trays are often difficult
to use. Among other things, food often gets pushed or rolls off of
these trays. The food then falls to the grill below, where it is
burned.
[0014] It is desired to provide a barbeque grill overcoming these
and other problems.
SUMMARY OF THE INVENTION
[0015] The present invention comprises various barbeque grill
components, and a method and system for constructing a grill island
or support structure.
[0016] One aspect of the invention is a grill unit comprising a
supporting structure comprising a plurality of individual modular
units. Each modular unit comprises a frame, the frame comprising a
plurality of interconnected elements generally defining a perimeter
of the unit and an open interior and a covering extending over at
least a portion of said frame, the covering enclosing at least a
portion of the frame and the interior. The modular units are
connected to one another to form a unitary structure, at least one
of the frame elements of each modular unit configured for mating
with a corresponding frame element of an adjacent modular unit.
When assembled, the frame elements of the modular units define a
generally contiguous front, top and rear of said grill unit.
[0017] In one embodiment each modular unit of the grill is
configured to support specific grill equipment. For example, one
modular unit is configured to support a cooking grill. Other units
may be configured to support and/or enclose a refrigerator, trash
bin, storage drawers or other equipment.
[0018] In one embodiment, the modular units used to construct the
grill unit may be a sub-set of units selected from a larger number
of possible units. The configuration of the grill unit may be
changed depending upon the assembled order of the units. The
modular units may be displayed in a showroom and configured
according to a customer's desires to demonstrate the desired grill
unit configurations. The modular units are then taken to the
desired location and assembled.
[0019] In one embodiment, the size of each modular unit is selected
so that the unit is easily transported and will pass through a
door. At the desired location, the modular units are connected. A
coating, such as stucco or tile, play be applied to the coating or
covering upon the frames of the unit to finish the unit.
[0020] In one embodiment, each modular unit has a pair of sides and
the frame of each modular unit at the sides are uncovered. Two of
the modular units comprise end units, the end units having a outer
covered side and an inner uncovered side of their frames, the
uncovered sides of the end units connected to a corresponding
uncovered side of another of the modular units.
[0021] One embodiment of the invention is a method of constructing
a modular unit of a grill assembly. In one embodiment, the method
comprises providing a first jig, the first jig having a generally
planar support surface and a plurality of stops connected thereto.
A plurality of frame elements are positioned upon the first jig in
a predetermined configuration, the position of the frame elements
defined at least in part by the position of the stops. The frame
elements are connect to one another to form a side frame. A second
jig is provided, the second jig configured to accept the side
frame. The side frame is placed on the second jig and a covering is
connected to at least a portion of the frame. Two side frames are
connected with one or more cross-pieces, the cross-pieces spacing
the side frames.
[0022] In accordance with this aspect of the invention, modular
units may be constructed in assembly line fashion. Frame elements
may be pre-cut or formed. Those frame elements are quickly placed
into the necessary positions on the jig so that they form the exact
frame structure desired.
[0023] Other aspects of the invention comprise grill components or
elements thereof. One embodiment of the invention comprises a
handle for a grill structure. The handle comprises a body having a
central section located between a pair of ends, the ends curved
away from the central section. Each end defines a generally planar
surface facing in a first direction for connection to a lid of a
grill. The body has an outer surface. A slot is formed in the outer
surface facing in a second direction generally opposing the first
direction, the slot being generally rectangular in cross-sectional
shape and extending along a length of the central section.
[0024] Preferably, the handle is constructed from metal. When
connected to a grill lid, the central section is spaced outwardly
from the grill lid, the slot facing away from the grill lid.
[0025] The handle of the invention has the advantage that it is
very durable and yet dissipates heat efficiently, permitting the
handle to be touched even when the grill lid is extremely hot.
[0026] Another aspect of the invention is a burner, the burner
configured to transmit gas such as propane, for burning. The burner
comprises a burner conduit which is generally "U" shaped and has a
first leg and second leg, the legs spaced from one another and the
conduit having a plurality of apertures formed therein. The burner
also includes a delivery conduit, the delivery conduit having a
central section having a first inlet end and an opposing end and a
first arm and a second arm. The first and second arms extend
outwardly from the central section generally opposite one another
along the central section from the first end, the first arm
connected to the first leg of the burner and the second arm
connected to the second leg of the burner.
[0027] The burner effectively distributes gas evenly throughout the
burner conduit, whereby the heat generated along the entire burner
is generally equal.
[0028] Another aspect of the invention is a rotisserie. The
rotisserie comprises a spit having a first end and a second end.
The rotisserie includes a support rollably supporting the first end
of the spit, the support connected to a portion of the grill. The
rotisserie also includes a spit drive driving the second end of the
spit. The spit drive includes a drive element and a drive
transmission. At least a portion of the drive transmission is
located in a housing and the drive transmission includes a socket
for accepting the second end of the spit, whereby when the drive
element drives the drive transmission, the drives transmission
rotates the second end of the spit, and the first end of the spit
correspondingly rotates upon the support.
[0029] In one embodiment, the drive transmission includes a first
gear and a second gear, the first gear connected to the second gear
with a drive element such as a chain. Preferably, both the first
and second gears and the drive element are located in the
housing.
[0030] In one embodiment, the housing comprises a hollow side wall
or side structure of the grill. The first and second gears are
mounted upon a support structure within the hollow portion of the
housing.
[0031] Another aspect of the invention comprises a warming tray for
use in a grill. The warming tray comprises a generally planar
support having a top and a bottom, a front edge and rear edge and a
pair of sides. The rear edge comprises an upturned lip, the lip
extending upwardly and inwardly towards said front edge.
[0032] In use, the warming tray is positioned inside of a grill.
The lip abuts a grill lid, the lip preventing food items from being
pushed or rolling off of the warming tray at the rear of the
grill.
[0033] Another aspect of the invention is a burner lid for use in
selectively covering a burner of a grill when said burner is not in
use. The burner lid comprises a lid body configured to cover the
burner when positioned over the burner, the body having a first
side and a second side.
[0034] A first elongate slot is formed in the first side and
extends therealong and a first pin is connected to a support
structure supporting the burner, the pin extending into engagement
with the first slot. A second elongate slot is formed in the second
side and extends therealong, the second pin connected to the
support structure and extends into engagement with the second
slot.
[0035] The mounting configuration of the burner lid permits the
body of the lid to be pivoted upwardly from a position in which it
extends over the burner to a position in which it is raised from
the burner, and whereby the lid body may be slid along the first
and second pins until the body is recessed from the burner.
[0036] Yet another aspect of the invention is a leveling foot. The
leveling foot is particularly suited for use in leveling a modular
unit of a grill structure constructed from a plurality of assembled
modular units, each modular unit comprising a frame with a
covering, the frame including at least two frame elements defining
a lower portion thereof, and at least two frame elements connected
to one another and extending perpendicular to one another. In one
embodiment, the foot comprises a body comprising a central mounting
section having a first end and a second end, the ends extending
along lines which intersect generally perpendicular to one another.
A first leg extends downwardly from the first end of the central
mounting section and a second leg extends downwardly from the
second end of the central mounting section. A first tab extends
outwardly from the first leg and a second tab extends outwardly
from the second leg, the first and second mounting tabs extending
in a plane generally parallel to plane containing the central
mounting section, whereby the first and second tabs may be
connected to the frame elements and the central mounting section
spans a space between the frame elements.
[0037] The foot also includes a stud connected to the central
mounting second of the body and a pad connected to the stud. The
stud is movable with respect to the central mounting section from a
position in which the pad is retracted to a position in which the
pad is extended away from the body.
[0038] One aspect of the invention is a bracket for use in
connecting the modular units. The bracket is configured to connect
two or more adjacent support elements, such as frame studs, of
modular units. The bracket provides a secure mechanical connection
for the modular units.
[0039] Further objects, features, and advantages of the present
invention over the prior art will become apparent from the detailed
description of the drawings which follows, when considered with the
attached figures.

DETAILED DESCRIPTION OF THE INVENTION
[0058] The invention includes methods and apparatus for
constructing barbeque grill units and various features of such
units. In the following description, numerous specific details are
set forth in order to provide a more thorough description of the
present invention. It will be apparent, however, to one skilled in
the art, that the present invention may be practiced without these
specific details. In other instances, well-known features have not
been described in detail so as not to obscure the invention.
[0059] One aspect of the invention is a method of creating modular
grill unit elements. Another aspect of the invention is a method of
creating barbeque grills from modular elements.
[0060] FIG. 1 illustrates one embodiment of a grill or barbeque
unit 20. As illustrated, the unit 20 has a base 22 which rests upon
a supporting surface, such as a patio. The base 22 supports one or
more grill components. As illustrated, the supported components are
a trash unit 24, a drawer unit 26 and a grill 28. The grill 28
preferably comprises a cooking grill of the type which comprises a
generally enclosed housing. A portion of the housing is preferably
defined by a movable lid. An interior of the housing is heated with
one or more burner elements, such as gas burners which transmit and
release natural gas or propane for burning.
[0061] In general, the base 22 is a solid supporting structure. As
illustrated, the base 22 is preferably enclosed and defines and
finished outer surface. The base 22 may be referred to as an island
or cabinet.
[0062] In accordance with the present invention, the grill unit 20
is constructed from a plurality of modular elements or units. In
one embodiment, a variety of different modular elements or units
are provided, providing for a nearly infinite number of resulting
grill unit configurations constructed from one or more of the
modular units.
[0063] One embodiment of a modular unit will be described with
reference to FIG. 2. FIG. 2 illustrates a plurality of modular
units 40. Each modular unit 40 has certain similarities. First,
each modular unit 40 includes a supporting framework 42. Second,
each modular unit 40 includes means for connecting it to another
modular unit. As described below, each modular unit 40 also
includes a covering over all or a portion of the framework 42 for
enclosing the unit 40.
[0064] FIG. 2 illustrates four particular modular units 40: a first
end unit 44, a second end unit 46, a grill unit 48, a burner unit
49 and a trash unit 50. The frame 42 of each unit is preferably
constructed from hollow galvanized steel studs 2'' by 4'' in
cross-sectional dimension. Preferably, these studs are cut to size
and connected to one another, such as with metal screws, to form
the frame 42 for each modular unit 40.
[0065] The particular configuration of the frame for each modular
unit 40 may differ depending on the intended use of the unit. For
example, in the case of the grill unit 48, the frame work defines
an opening at a front and a top to accommodate a grill, as
illustrated in FIG. 1.
[0066] Generally, the frame 42 of each modular unit 40 includes one
or more frame elements for defining a base, top, opposing sides, a
front and a back thereof. The portion of the frame 42 defining the
base is preferably configured to support the modular unit 40. As
illustrated, this may comprise a number of frame elements forming a
base perimeter.
[0067] The portions of the frame 42 defining the front and rear are
preferably configured to support a covering and one or more grill
components. Similarly, the portion of the frame 42 defining the top
is configured to define a covered top surface and/or support one or
more grill components.
[0068] Preferably, the modular units 40 are sized for easy
transport and assembly, and so that when assembled, mating modular
units define a contiguous element. In one embodiment, the modular
units 40 have a depth of no more than 36 inches, permitting them to
be transported through standard doorways. In one embodiment, the
height of the modular units 40 also is no more than about 36
inches. The exact height of the units 40 may depend, however, upon
the application.
[0069] In the preferred embodiment, the modular units 40 are
pre-constructed and then transported to the assembly site. A
preferred embodiment for constructing the modular units 40 is
described in more detail below.
[0070] As described above, the modular units 40 are preferably
constructed for connection to one another. In one embodiment, each
modular unit 40 includes at least one commonly located support
element. As illustrated in FIG. 2, each modular unit 40 includes a
upwardly extending front and rear supports 52,54. The front and
rear supports 52,54 of each modular unit 40 are located the same
distance from one another.
[0071] In one embodiment, the units 40 may selectively be connected
using fasteners. In one embodiment, the front and rear supports
52,54 of each modular unit 40 include one or more passages or
apertures 56. These passages 56 align with one another when the
modular units 40 are located side-by-side with their front and rear
supports 52,54 positioned adjacent one another. In this
configuration, fasteners may be passed through the passages 56. The
fasteners, such as screws or nut/bolt combinations may be used to
secure the modular units 40 to one another.
[0072] As indicated, the frame 42 of each modular unit 40 is
preferably created or configured to support one or more grill
elements. For example, as illustrated in FIG. 2, one of the modular
units 48 defines an opening at a front and top thereof for
accepting therein a grill unit as illustrated in FIG. 1. Similarly,
a second of the modular units 50 defines an opening at front
thereof for accepting a trash unit as illustrated in FIG. 1.
[0073] Preferably, the frame 42 of each modular unit 40 defines a
perimeter supporting structure. An interior space within each frame
42 is generally open for housing components and/or to reduce the
total weight of the modular unit.
[0074] When constructed, it is desirable for the constructed grill
unit 20 to be enclosed. Because the frame structures 42 are open, a
covering 58 is applied to the modular units 40. One aspect and
advantage of the frame construction of the modular units 40 is that
not all surface thereof need to be covered. Referring to FIG. 2,
when two modular units 40 are connected side-by-side, their open
frames may be connected directly to one another without any
covering because those sides are not exposed. In addition, it is
generally not necessary to cover the base portion of the frame 42,
though it may be desirable to add an interior "floor" when the
interior of the modular unit 40 is used for storage.
[0075] Preferably, the other areas such as the exposed top, front
and rear are covered. In one embodiment, the cover 58 may comprises
a fire-resistant or retardant wall board. The cover 58 may be
affixed to the frame 42 with fasteners such as screws.
[0076] In one embodiment, the exposed sides of connected modular
units 40 are preferably covered. Covering may be applied for this
purpose. In a preferred configuration, specially configured end
units 44,46 are connected to the exposed sides of the modular unit
or connected modular units. Preferably, the end units 44,46 again
comprise a frame 42 including supports configured for connection to
corresponding supports of the other units 40. The side of the frame
of the end unit 44,46 which is to be exposed, however, is
preferably covered with a cover 58
[0077] One embodiment of the invention a method of constructing a
grill or barbeque using the modular units 40. First, a grill
manufacturer may build each desired modular unit, such as using the
preferred method described below. The modular units may be
displayed on a showroom floor. In a preferred configuration, the
modular units are mounted upon wheels or rollers so that they may
be moved. The displayed modular units may be enclosed on all sides,
for reasons which will become apparent.
[0078] Preferably, the modular units may be selected and then
rolled into position to create various simulated grill
configurations. In particular, a customer may select various of the
modular units and roll them into a first configuration. The
customer may select other units or change the arrangement of the
units to create other configurations. In this manner, the customer
may actually see various completed grill unit configurations before
such a configuration is assembled at their home. This allows the
customer to be sure that their desires are met.
[0079] As described, the sides of each modular unit may be covered
so that no matter what configuration the modular units are arranged
into, the sides of the assembled configuration are closed, much in
the same manner as the completed structure will be when
assembled.
[0080] Once the customer has selected a particular grill
configuration, the configuration may be assembled at the desired
location, such as the customer's home. Preferably, each modular
unit which is to comprise the assembled grill is constructed, such
as in the manner described below. These modular units are then
transported to the customer's home. Because of their size and
construction, each modular unit is lightweight, and thus easy to
load and transport. In addition, because of the size of each
modular unit, the units are conveniently transported through
doorways and other passages, such as through a home to a rear
patio.
[0081] At the desired site, the modular units are connected to one
another. As described above, this is preferably accomplished with
the use of fasteners connecting mating portions of the units. As
described, the assembly preferably includes end units which close
the ends of the assembled unit.
[0082] Once the modular units are assembled, a generally enclosed
support structure is defined. In one embodiment, part of the
construction of the modular units includes not only forming the
frame and covering thereof, but mounting grill unit components,
such as drawers, trash bins, a grill or other elements. In one
embodiment, some or all of these components are associated with
their corresponding units before the units are assembled. In
another embodiment, such components are not associated with the
units until after the units have been assembled.
[0083] As described, the covering of the units is an unfinished
covering. This allows each customer to customize the finish of the
grill unit to their desires. For example, in one embodiment a
synthetic stucco is applied to the covering. The synthetic stucco
may be pre-colored or be painted after application. Other finishes
may be applied, such as stone, tile or the like.
[0084] In the preferred embodiment, after finishing, the grill
components are connected to the assembled grill unit. This may
include the connection of a gas line to the grill, connection of
electrical lines and the like.
[0085] As described, the assembled unit is mounted upon a support
surface. In one embodiment, the assembled unit may be permanently
connected to the surface, such as with bolts. In another
embodiment, wheels, rollers or the like may be connected to the
modular units, permitting the assembled unit to be moved.
[0086] In one embodiment, the modular units are mounted on feet. A
preferred configuration of a foot of the invention is illustrated
in FIGS. 9(a) and 9(b) and described in detail below. Preferably,
the feet are adjustable, permitting the assembled unit to be
leveled even when the supporting surface is not level.
[0087] The grill unit assembly and method of construction have, as
indicated, numerous advantages. The modular construction permits
pre-assembly into various configuration for visualization of the
ultimate assembled configuration.
[0088] The modular construction also reduces the time and cost
associated with grill unit construction. While only a certain
number of pre-configured modular units need to be constructed, a
nearly limitless variety of end configurations can be desired.
Because the modular units are pre-configured, however, they may be
mass constructed in a manner which saves time.
[0089] The modular construction has the advantage that each unit
has its own supporting framework. Each frame is sufficient for the
modular unit to be self-supporting. When connected, the assembly is
then even stronger. This contrasts with custom-configured grill
structures where the structure generally comprises a single
free-standing open frame structure. The structure may have long
open spans, reducing the strength of the structure in certain
areas.
[0090] Because the modular units are specially configured to be
assembled to one another, they may be quickly connected at the
desired location. No hole drilling or other special work needs to
be done to connect the units, again saving time.
[0091] Because of the open frame construction, including interior
non-covered sides of the units, not only are the modular units
strong and light-weight, but the assembly is lightweight. This
permits the unit to be easily moved if that is necessary.
[0092] Another aspect of the invention is a method of constructing
the modular units of the invention. One embodiment of the invention
will be described with reference to FIGS. 3(a) and 3(b).
[0093] FIG. 3(a) illustrates a jig 300. The jig 300 comprises a
"template" for use in constructing at least a portion of a frame.
In a preferred embodiment, the constructed frame comprises a
portion of a modular unit such as that illustrated in FIG. 2 and
described above.
[0094] The jig 300 includes a base 302. In a preferred embodiment,
the base 302 comprises a generally planar support surface. The base
302 may be oriented in a variety of positions. In a preferred
embodiment, the base 302 is supported on a stand (not shown) such
that it angles upwardly between horizontal and vertical, such as an
angle of 45-60 degrees. In one embodiment, the base 302 comprises a
supporting frame and flat sheeting, such as plywood, which forms
the planar work surface.
[0095] In a preferred embodiment, various stops 304 are affixed to
the base 302 and extend outwardly therefrom. In one embodiment, the
stops 304 comprise "L" shaped angle iron members which are affixed
to the base 302 with fasteners such as screws. The stops 302
comprise members which are used to support various frame elements
and/or align various frame elements which are located on the base
302.
[0096] Importantly, the stops 304 are affixed to the base 302 in
positions so that they support and/or align the various frame
elements in the desired positions necessary to create the frame. In
one embodiment, a stop 304 may extend along the edges of the base
302, thus forming a supporting/stopping perimeter. Various other
stops 304 are located interior to this perimeter.
[0097] It will be appreciate that the configuration of the jig 300
may vary depending upon the particular frame which is to be
constructed. The particular configuration of the jig 300 is useful
in constructing a portion of a frame of the grill unit 48
illustrated in FIG. 2.
[0098] In this embodiment, frame elements 306 are positioned
against the base 302 and against and/or around the stops 304 in
order to form the desired frame. As described above, the frame
elements 306 may comprise metal studs or the like. Preferably, the
frame elements 306 are cut or formed to length and then positioned
in the jig 300. The frame elements 306 are then connected to one
another, such as with fasteners or welding.
[0099] In the example illustrated, the grill unit 48 includes a
central opening. As such, stops 304 are associated with the base
302 in positions such that, when frame elements 306 are mounted
thereabout, the frame elements form the opening.
[0100] In order to aid the user in arranging the frame elements 306
around and against the stops 304 to form the desired frame
configuration, the locations of the frame elements may be drawn or
depicted on the base 302, such as in an outline format. The outline
may also include an indication of the particular frame elements 306
to be positioned in each location, such as by an identifier such as
a frame element number. In this manner, the user may simply obtain
required frame elements, positioned them in the correct locations
on the jig 300, and then fasten them together.
[0101] The embodiment jig 300 illustrated in FIG. 3(a) is
preferably configured for use in assembling the frame elements and
the associate covering. As such, the jig 300 includes a frame
section 308 and a covering section 310. The frame section 308
includes stops 304 configured for use in arranging the frame
elements.
[0102] As described above, the frame of a constructed modular unit
is covered with a covering. In accordance with the invention, once
a particular frame section is constructed, the covering may be
applied using the jig 300.
[0103] The covering section 310 includes stops 304 configured to
accept the frame section assembled on the frame section 308 of
thejig 300 in "reverse" position. In other words, the location of
the stops 304 are mirror imaged about an axis 312.
[0104] In use, the assembled frame section 308 is turned over by
rotating it from the frame section 308 to the covering section 310
of the jig 300 about the axis 312. The frame section then rests
upon the jig 300 so that an exterior thereof faces outwardly. A
covering 314 such as that described above may then be affixed to
the framing section. In one embodiment, the covering 314 may be
pre-cut, such as with desired openings. The covering 314 may then
be positioned on the frame section and attached with fasteners or
the like.
[0105] In accordance with the invention, multiple jigs 300 of
different configurations may be used to construct the frame
sections forming the frame of a single modular unit. As indicated,
FIG. 3(a) illustrates a jig 300 for use in constructing the front
portion of a frame of a grill unit 48 as illustrated in FIG. 2.
[0106] A similar but differently configured jig 300 may be used to
construct a back frame section of the frame. As illustrated in FIG.
3(a), the constructed front and rear sections 330,332 may then be
connected with one or more cross-pieces 334. It will be appreciated
that this configuration is advantageous because the sides of the
modular units of the invention are not covered. As such, once the
front and back sections of the frame are covered and then connected
by any side or cross-pieces, the modular unit is in constructed
form.
[0107] This aspect of the invention has numerous advantages over
the prior art. As described above, in the prior art grill units
generally comprise one component or structure, or when larger,
comprise a custom built component. In the case of large outdoor
grill structures, a supporting frame is generally custom assembled.
This requires the assembler to custom form or cut frame pieces and
then connect them to one another without regard to any particular
sequence or configuration. As a result, these frameworks generally
take a great deal of time to construct, and each being different
from the next, without regarding to the most efficient frame
configuration when considering the strength, durability or ease of
assembly. In essence, each frame structure is assembled as a trial
and error project.
[0108] In accordance with this aspect of the invention, including
the jig and method of use thereof, the modular units of the
invention may be constructed in a very short period of time. This
is because the multiple frame elements can be preformed or cut and
their configuration is pre-determined. Further, each constructed
modular unit is configured for the greatest ease of assembly. Each
modular unit is also the same as the next, such that they are all
compatible, as when connected to one another. In essence, the
method of the invention results in the ability to "assembly line"
create the modular units.
[0109] Various aspects of the invention comprise particular
barbeque or grill features or elements. It will be appreciated that
these features and elements may be used apart from one another or
together, and may be incorporated into various grill or barbeque
configurations, including a barbeque constructed as described
above.
[0110] FIG. 4 illustrates a grill handle 400 of the invention. The
grill handle 400 is particularly suited for connection to a grill
lid for use in moving the grill lid between open and closed
positions. As illustrated, the grill handle 400 comprises a body
402 having a first end 404 and a second end 406. The body 402 has
an outer surface 408.
[0111] The handle 400 is desirably constructed from a durable,
strong, weather resistant material. In a preferred embodiment, all
or a portion of the body 402 of the handle 400 is constructed from
metal. The handle 400 may be constructed from aluminum, stainless
steel or the like.
[0112] In one embodiment, the body 402 of the handle 400 is
somewhat "C"-shaped, curving at its ends 404,406. In one
embodiment, the ends 404,406 are configured for connection to a
grill lid, and as such curve inwardly so that a generally planar
end surface thereof can be mounted flush to the grill lid. A
central section of the handle 400 preferably extends between the
ends 404,406. Because of the curving shape of the ends 404,406, the
central section is positioned outwardly of a grill lid to which it
is connected, permitting a user to grip the central section without
contacting the grill lid.
[0113] In the embodiment illustrated, when mounted to a grill lid,
a portion of the outer surface 408 faces towards the grill lid, and
a portion faces outwardly. In a preferred embodiment, a portion of
the body 402 between the ends 404,406 is removed. As illustrated, a
slot 410 is formed in the body 402 in the portion of the grill lid
which faces outwardly. In one embodiment, the slot 410 is generally
rectangular in shape.
[0114] In one embodiment, the cross-sectional shape of the body 402
is circular. The size of the body 402 may vary.
[0115] The handle 400 of the invention has several advantages. A
particular advantage of the handle 400 is that it dissipates heat.
Thus, when connected to a heated item, such as a grill lid, the
temperature of the handle 400 remains very low, permitting a user
to grab or touch it without being burned. In particular, the
reduced cross-sectional area of the handle 400 in the area of the
slot 410 reduces thermal transfer. In addition, the slot 410
results in a greater outer surface area than if the body 402 were
merely circular in shape, increasing the rate of heat dissipation
to the air.
[0116] Another aspect of the invention is illustrated in FIG. 5.
FIG. 5 illustrates a warming tray 500 in accordance with the
invention. The warming tray 500 is configured to be placed inside
of a grill unit and to support food items thereon for warming.
[0117] As illustrated, the warming tray 500 is generally planar,
having a top surface 502 and a bottom surface 504. The warming tray
500 has a front edge 506, a rear edge 508, and a pair of opposing
sides or side edges 510,512. In one embodiment, as illustrated, the
front and side edges 506,510,512 all include a under-turned lip,
presenting a smooth, rolled edge to the user (rather than an abrupt
sharp edge).
[0118] The warming tray 500 may be constructed of a variety of
materials. Preferably, the tray 500 is constructed of a
heat-durable material such as stainless steel.
[0119] As illustrated, the generally planar central section of the
warming tray 500 may have a plurality of apertures therein to let
heat therethrough, in a convective fashion. It is also possible for
the tray to have a solid construction.
[0120] In accordance with the invention, the rear edge 508 of the
warming tray 500 curves upwardly and inwardly. As illustrated, the
rear edge 508 is defined by a lip 514. The lip 514 extends upwardly
from the main generally planar portion of the tray 500, and bends
forward towards the front edge 506 of the tray 500. In this
configuration, the lip 514 has an inside surface and an outside
surface.
[0121] The warming tray 500 of the invention has the advantage that
food items are maintained on the tray when the tray is in use. As
indicated, the tray 500 is preferably used within a grill.
Generally, the tray 500 is located inside an open space in the
grill above the burners and one or more cooking grills. In one
embodiment, the tray 500 is configured to be located in a grill
such that the lip 514 thereof abuts the inside of a grill lid (not
shown). Advantageously, food items located on the top 502 of the
tray 500 are prevented from being pushed, rolling or otherwise
moving off of the rear portion of the tray 500 by the lip 514.
These food items are caught by the lip 514 and maintained on the
tray 500.
[0122] Another aspect of the invention a gas burner for a grill,
barbeque or other cooking unit. A burner 600 of the invention is
illustrated in FIGS. 6(a) and 6(b). The burner 600 includes a
conduit 602 for transmitting gas, such as natural gas or propane.
The conduit 602 may comprise a stainless steel pipe or similar
element. In such a configuration, the conduit 602 is defined by a
wall and has an open interior or passage through which gas may
flow.
[0123] As illustrated, the burner 600 has an inlet 604 through
which gas is delivered. The inlet 604 may be connected to a gas
source in a variety of manners.
[0124] As illustrated, the conduit 602 includes a generally
"U"-shaped gas burner section 606. The burner section 606
preferably has a pair of closed ends. As illustrated in FIG. 6(b),
the burner section 606 has a plurality of apertures 608. The
apertures 608 extend through the wall of the conduit 602 from an
interior to the exterior thereof.
[0125] The number of apertures 608 may vary in size and in number,
depending upon the application. For example, the size of the
apertures 608 may vary depending on whether the burner 600 is
configured to burn propane or natural gas. Preferably, one or more
or all of the apertures 608 are located in a portion of the burner
section 606 which corresponds to a top of the burner 600.
[0126] As illustrated, the conduit 602 includes a "T"-shaped
delivery section 610. The delivery section 610 has a main section
612 defining the inlet 604. In addition, the delivery section 610
has a pair of arms 614,616 extending outwardly from the main
section 612.
[0127] As illustrated, the burner section 606 has a first leg 618
and an opposing second leg 620. One of the arms 614 of the delivery
section 610 leads to the first leg 618, while the other arm 616
leads to the second leg 620. Preferably, the arms 614,616 are
aligned and are of generally the same length.
[0128] In one embodiment, a diverter or shield 622 is associated
with the burner 600. The diverter 622 serves to spread heat created
by the burning gas and prevent open flame from burning food being
cooked.
[0129] In accordance with the burner 600 of the invention, gas is
delivered through the inlet 604 to the main delivery section 612.
The gas is then evenly distributed through the arms 614,616 to the
burner section 606. The gas passes into the burner section 606 and
is evenly distributed therein and then burns as it exits the burner
section 606 through the various apertures 608.
[0130] A common problem when facing burner design is to create an
even heat source over a large area. Because of the burner
configuration, the flame/burn intensity at various locations of the
burner 600 is generally equal. In particular, because of the "T"
shape of the delivery section and its mating to the "U" shaped
burner, gas pressure within the length of the burner section is
generally equal, providing for even burner rate and heat.
[0131] Another aspect of the invention is an improved burner lid
mounting. This aspect of the invention will be described with
reference to FIGS. 7(a) and (b). Various grills, barbeques and
other cooking devices include burners. The burners may be electric
or gas powered. Often, it is desirable to protect a burner. For
example, in the case an outdoor grill, the burner may need to be
protected from the elements. A lid or cover may be located over the
burner when the burner is not in use.
[0132] FIG. 7(a) illustrates a burner lid 700. The lid 700 may have
a variety of shapes and configurations. In one embodiment, the lid
700 is generally rectangular in shape. The lid 700 has a pair of
elongate sides 702. As illustrated, in one position the lid 700 is
configured to extend over a burner.
[0133] Referring to FIG. 7(b), a slot 704 is formed in one, and
preferably both, sides 702 at an interior thereof. Preferably, a
pin 706 is connected to a lid support structure, such as a housing
to which the burner is mounted. The pin 706 extends outwardly and
engages the slot 704.
[0134] The lid 700 is preferably configured so that it can be moved
from a first position in which it is generally horizontal and
positioned over the burner to a raised position in which it is
positioned upwardly from the burner, providing access to the
burner. This movement is preferably accommodated by the position of
the lid relative to the surrounding structure(s) and the rotatable
mounting of the pin 706 in the slot 704.
[0135] In a preferred embodiment, the lid 700 can additionally be
moved from its raised position to a stored position. A space may be
provided for housing the lid 700. As illustrated, this space is
defined by the burner support structure or housing, and is located
behind the burner. In accordance with the invention, after the lid
700 is rotated to its raised position, the lid 700 may be slid
downwardly into the storage space. This movement is facilitated by
travel of the pin 706 along the slot 702 as the lid 700 is moved
relative to the pin 706.
[0136] Another aspect of the invention is a rotisserie and
rotisserie drive system which will be described with reference to
FIGS. 8(a)-(e). As illustrated in FIGS. 8(a) and 8(b) a rotisserie
system 800 of the invention is useful with a grill having a body
with a lid.
[0137] Referring to FIG. 8(b), the rotisserie 800 is preferably
mounted to a pair of walls 802,804. In one embodiment, the walls
802,804 may be side walls of the grill.
[0138] Referring to FIG. 8(c), the rotisserie 800 includes a spit
806. As illustrated, the spit 806 is an elongate body, preferably
having the form of a rod. In one embodiment, the cross-sectional
shape of the spit 806 is other than circular, such as square, so
that food items placed thereon will rotate with the spit 806.
[0139] Referring to FIGS. 8(c) and 8(e), the spit 806 has a first
end 808 and a second end 810. In one embodiment, the first end 808
of the spit 806 is a tapered head or point (i.e. having a circular
cross-section which reduces in size). The rotisserie 800 includes
means for supporting the first end 808 of the spit 806 for
rotation. As illustrated, the means comprises first and second
rollers 812,814.
[0140] As illustrated in FIGS. 8(b) and (c), in one embodiment, the
rollers 812,814 are mounted to a bracket 815. The bracket 815 is,
in turn, mounted to the grill, such as the wall 802 of the grill.
The rollers 812,814 are mounted for rotation and are spaced from
one another. As illustrated, the first end 808 of the spit 806 is
supported by the rollers 812,814. In this configuration, the first
end 808 of the spit 806 is rotatably supported by the rollers
812,814.
[0141] The rotisserie 800 includes means for rotating the spit 806.
In one embodiment, the means comprises a drive for rotating the
second end 810 of the spit 806. The drive includes a drive element
and a drive transmission.
[0142] As best illustrated in FIGS. 8(d) and (e), the drive
transmission includes a first gear 816 and a second gear 818. Means
are provided for rotating the first gear 816. In one embodiment,
this means comprises the drive element, namely an electric motor
820. The first gear 816 is configured to rotate the second gear
818. In one embodiment, this means comprises a drive chain 822 of
the drive transmission. The second gear 818 is configured to drive
the second end 810 of the spit 806. In one embodiment, a socket 824
is associated with the second gear 818. The socket 824 is
configured to accept the second end 810 of the spit 806.
[0143] In the preferred embodiment of the invention, various of the
component of the drive are enclosed in a housing so as to be
protected from the elements and from contact with a user of the
grill. As illustrated, the wall 804 of the grill is preferably
formed with an interior space 826 in which the first and second
gears 816,818 are mounted.
[0144] In one embodiment, referring to FIG. 8(d), the first and
second gears 816,818 are mounted for rotation to a mount 828. The
mount 828 is located in the interior space 826 and connected to the
wall 804. The mount 828 may be connected to the wall with
appropriate fasteners or by other means, such as welding.
[0145] As illustrated, an opening is provided in the wall 804 which
provides access to or through which the socket 824 extends.
Preferably, a similar opening is provided on the opposing side of
the wall at the first gear 816. A similar socket or drive is
provided for interfacing the motor 820 with the first gear 816.
[0146] In use, the motor 820 is connected to the first gear 816.
The motor 820 turns the first gear 816, which turns the second gear
818 via the drive chain 822. The second gear 818 rotates the spit
806 via its connection at the socket 824.
[0147] Various other embodiments of the rotisserie 800 are
contemplated. First, other drive means may be provided for driving
or rotating the spit 806. The first and second gears 816,818 may be
in a direct drive arrangement. The gears 816,818 may comprise
pulleys which are connected via a drive belt. The motor 820 may be
connected to a single gear which in turn drives the spit 806.
[0148] Preferably, however, one or more of the drive components are
housed within an interior housing. As indicated, the housing
preferably comprises an interior or exterior side wall of the
grill. In other embodiments, the housing may be separate from the
grill and may be attached or set upon the grill when used.
[0149] In accordance with the invention, the rotisserie drive
components are protected from dirt, damage and from contact with a
user. This configuration is aesthetically appealing, safer, and
more durable.
[0150] As described above, it is desirable to level the grill unit
of the invention when it is installed. One embodiment of the
invention comprises a leveling foot 900. As described, the foot 900
is particularly suited to use in leveling one or more modular units
having a supporting frame, as described above. The foot 900 may be
used in other environments, however, including for use in leveling
other types of grill structures and elements and items other than
grills.
[0151] As illustrated in FIG. 9(a), the foot 900 includes a
mounting body 902, a stud 904 and a pad 906. In general, the body
902 is configured to mount the foot 900 to a structure to be
leveled. The stud 904 engages the body 902, the position of the
stud 904 being movable relative to the body. The pad 906 engages a
support surface. When the stud 904 is moved, the position of the
pad 906 from the body 902 changes, allowing the position of the pad
906 to change relative to a support structure.
[0152] In a preferred configuration, it is desired that the body
902 be configured to mount to a corner portion of a structure. In
one embodiment, the body 902 is particularly suited to mounting to
frame elements of a frame such as that illustrated in FIG. 2, i.e.
a frame of a modular grill unit.
[0153] As illustrated, the body 902 has a central mounting section
908. The central mounting section 908 is generally planar. A pair
of legs 910,912 extend downwardly from the central mounting section
908 at each end thereof. Preferably, the legs 910,912 extend
downwardly a distance greater than the minimum distance the pad 906
extends outwardly when the stud 904 is in it retracted position,
for reasons described below.
[0154] Mounting tabs 914,916 extend from the legs 910,912. As
illustrated, the legs 910,912 extend outwardly in a plane which is
generally parallel to, but offset from, the central mounting
section 908.
[0155] As illustrated in FIG. 9(b), the foot 900 is configured to
mount to frame elements which are connected perpendicular or nearly
perpendicular to one another. Preferably, the foot 900 fits within
a corner space defined between the two mating frame elements.
[0156] As illustrated in FIG. 9(a), the ends of the central
mounting section 908 are angled. In a preferred embodiment, the
ends 908 are configured such that lines which extend along the ends
intersect at a 90 degree angle.
[0157] The legs 910,912 preferably extend downwardly from the
central mounting section 908 perpendicular thereto. The mounting
tabs 914,916 extend outwardly generally perpendicular to the legs
910,912.
[0158] In this configuration, as illustrated in FIG. 9(b), the body
902 of the foot 900 is configured to fit between the two frame
elements. The legs 910,912 engage the inner surfaces of the frame
elements, while the central mounting section 908 extends through
the corner space between the frame elements. The mounting tabs
914,916 are configured to engage the bottom surface of the frame
elements. As illustrated, the mounting tabs 914,916 extend inwardly
of an edge of the frame elements generally perpendicular
thereto.
[0159] The body 902 may be connected to the frame elements with
fasteners, such as metal screws. In one embodiment, each mounting
tab 914,916, includes an aperture 918 for accepting such a fastener
therethrough.
[0160] In one embodiment, the stud 904 comprises a rod. At least a
portion of the external surface of the stud 904 is threaded. The
threads of the stud 904 are configured to mate with corresponding
threads on or associated with the body 902. In one embodiment, an
aperture 920 is provided in the central mounting section 908, the
inner surface of which is threaded. In a preferred embodiment, a
nut 922 is connected to the central mounting section 908 at the
location of the aperture 920, the nut defining an inner threaded
passage. The nut 922 may be connected to the body 902 by welding or
the like.
[0161] The pad 906 is preferably connected to an end of the stud
904 which is on the side of the central mounting section 908 facing
the legs 910,912. In one embodiment, the pad 906 is a generally
circular support. The pad 906 may have a variety of constructions.
For example, the pad 906 may simply comprise a metal plate which is
welded to the stud 904. In another embodiment, the pad 906 may have
a supporting base, such as constructed of metal, and a non-slip, no
mark plastic insert which defines a bottom surface thereof.
[0162] In a preferred embodiment, the pad 906 is connected to the
stud 904 in a manner which permits it to rotate about an axis
passing through the stud 904. The pad 906 may also be permitted to
swivel or tilt relative to the stud 904 to conform to uneven
support surfaces.
[0163] As described above, in use, the foot 900 is mounted to a
structure. The body 902 is mounted so that it is recessed into the
space between the frame elements. The body 902 may be connected to
the frame elements as described above.
[0164] The stud 904 may be moved from a retracted to an extended
position. In the retracted position, as described above, the pad
906 preferably does not extend below the mounting tabs 914,916, and
thus does not extend beyond the bottom of the frame elements. Where
the stud 904 engages the body 902 in a threading configuration, the
stud 904 may be moved towards its extended position in an infinite
number of steps or positions. As the stud 904 is moved to its
extended position, the pad 906 extends outwardly beyond the bottom
of the frame elements for contacting a supporting surface.
[0165] The stud 904 may be moved outwardly until it no longer
engages the body 902. In another embodiment, the stud 904 may have
a stop which defines its extended position. The stop may comprise,
for example, the end of the threaded portion thereof or an enlarged
head or the like at its end opposite the pad 906.
[0166] So configured, when structure is set into position, the pad
906 of the foot 900 may be lowered until it engages the support
surface. It is desirable that the foot 900 be used at one or more
corners or other location of the structure to support the structure
at multiple locations. Each pad 906 of each foot 900 extending
downwardly the particular distance for engaging the support
surface.
[0167] As described above, in a preferred embodiment of the
invention, a grill unit is constructed from a number of discrete or
individual modular units which are connected to one another. In one
embodiment, the modular units are connected with fasteners or the
like.
[0168] FIG. 10 illustrates another means for joining the modular
units. The means comprises a bracket. In one embodiment the bracket
is defined by a body having a central, generally planar section
1002 and a pair of outwardly extending flanges 1004,1006. The
flanges 1004,1006 are spaced from one another and extend outwardly
from the central section 1002 generally perpendicular thereto. The
spacing of the flanges 1004,1006, and thus the width of the central
section 1002, is preferably dependent upon the number of elements
to be joined. In a preferred embodiment, the bracket is utilized to
join stud or frame elements of one or more modular grill units. As
illustrated, the bracket is configured to join to studs S. The
spacing of the flanges 1004,1006 is preferably then sufficient so
that the flanges extend along opposing sides of the two studs S. Of
course, the flanges 1004,1006 would be spaced apart a greater
distance if the bracket were being used to connect three adjacent
studs or frame members. Preferably, the spacing of the flanges
1004,1006 is such that the flanges 1004,1006 are located proximate
or against the sides of the studs or other frame elements (and not
spaced outwardly therefrom) when the bracket is connected
thereto.
[0169] As illustrated, the bracket includes a plurality of
apertures 1008 for accepting fasteners. Preferably, these apertures
1008 are configured for alignment with mating (pre-formed or
post-formed) apertures in the studs or frame elements which are to
be joined. As illustrated, in one embodiment, apertures are located
in the central section 1002 and flanges 1004,1006 of the bracket
for alignment with mating apertures in the edges and sides of the
studs S.
[0170] Preferably, the flanges 1004,1006 extend outwardly from the
central section 1002 a sufficient distance to engage an outside
surface or side of the set of two or more studs or other frame
elements. As illustrated, corner portions of the flanges 1004,1006
may be rounded or trimmed to eliminate sharp corners.
[0171] In one embodiment, fasteners such as bolts, rivets, metal
screws or the like may be used to join the bracket to the studs
when the studs or frame elements are metal (the bracket could also
be welded or soldered to the studs, although such direct connection
could be used to join the studs without the bracket) or by use of
nails, screws or the like when the studs are wood. When so
connected, the bracket engages the studs or frame elements,
maintaining them in a close connected relationship. One advantage
of the bracket is that it surrounds at least a portion of the studs
or other frame elements, joining them and preventing their movement
at least in part even without direct connection with fasteners.
Another advantage is that the bracket can be disconnected,
permitting the modular units to be separated, if desired.
[0172] It will be understood that the above described arrangements
of apparatus and the method therefrom are merely illustrative of
applications of the principles of this invention and many other
embodiments and modifications may be made without departing from
the spirit and scope of the invention as defined in the claims.
