Cooking apparatus
A cooking apparatus that has a support stand having a grill coupling section and a grill assembly releasably coupled with the coupling section of the support stand, and the grill assembly having a stand alone leg assembly which is supported by the support stand when the grill assembly and support stand are coupled. The coupling assembly preferably includes a telescoping relationship as in a projection off the grill assembly received in a pedestal stem representing the support stand which is at a height suited for stand up cooking. The leg assembly is preferably provided with an interconnected linkage and slide assembly which allows for the legs to expand out and lock in place and to then be collapsed again for telescopic insertion into the pedestal stem as in a collapsed state which allows for a free dangling extension in the support stem while the projection is in sliding contact with the upper cavity surface of the stem. The coupled grill assembly and the support stand are also preferably secured in coupled position with a securement assembly as in hand manipulatable latch(es) and/or fastener(s). One embodiment features a gas grill with gas burner and rigid gas supply line attached to a grill base body or the projection or some other portion of the grill assembly so as to allow a gas supply source to be maintained fastened to the grill assembly during coupling or removal of the grill assembly relative to the support stand.
The present application is a continuation-in-part of U.S. patent application No. 29/194,932 filed Dec. 4, 2003, and which is incorporated herein by reference.
FIELD OF THE INVENTIONThe present invention is directed at a cooking apparatus with a preferred embodiment featuring a self-integrated grill assembly, and a support and grill assembly combination comprising the self-integrated grill as well as a support device (e.g., a stand-up pedestal support which couples or interconnects with the self-integrated grill assembly).
BACKGROUND OF THE INVENTIONA variety of supported grill assemblies can be seen in the prior art such as the pedestal grill assemblies presented in U.S. Pat. Nos. 3,931,805; 5,404,795; 5,875,772 and EP 018692. These pedestal supports are intended to provide a grill unit that is at a desired “stand-up” cooking height relative to a standing person. They are rather cumbersome and are not generally designed for mobile transport and hence are not generally deemed mobile in nature, or, if are utilized in mobile fashion, are not well suited for easy transport with regard to size, shape, and/or weight.
There is also seen in the art a variety of smaller, typically less heavy, low height grills that are versatile in the sense of being light and of small volume for easy transport (e.g., from the garage or house out to the lawn or to a vehicle for use at a park, campground, sporting event tailgate party or the like).
There is also a need in the art for improved cooking waste capture as in grease dripping down to the base of a grill assembly. There is also room for improvement in the prior art for improved heat dissipation within a grill assembly.
SUMMARY OF THE INVENTIONThe present invention includes a cooking apparatus that is highly versatile in providing the advantages of a supported grill assembly (e.g., a pedestal supported grill assembly) as well as a removable grill assembly releasably attachable to a support stand of the supported grill assembly. A preferred embodiment features a removal grill assembly that is self-integrated or stand alone (e.g., can be removed from the support structure and has its own support structure which is, for example, lighter and/or shorter in nature as compared to the less mobile “stand-up” support stand). Preferably the grill assembly is fully integrated with no additional components needing to be attached or utilized, except for, perhaps, fuel source means, as in a gas tank or cylinder, fuel briquettes, etc.). Thus, an embodiment of the invention provides a cooking apparatus, which includes, in one mode of use, the combination of a support device and grill supported by the support device, and, in a second mode of use, involves a removed self integrated grill assembly, as in “ready for immediate use” without further grill attachments and/or assembly or disassembly. For example, a grill housing with integrated, manipulatable leg support assembly that is adjustable between a storage mode and a grill in operation mode, as in a collapsing and expanding leg assembly which remains fixed to the grill's main housing during both states.
The present inventions cooking apparatus includes a removable grill assembly and a stand-up grilling embodiment with a support stand that places the grill assembly at a higher level for ease in stand-up cooking without environmental height increasing support structures. For example, under the present invention there is provided a stand up cooking grill assembly mode and a mobile grill assembly mode which modes allow for a greater variety of usage environments as in different location low level ground usage or environmental higher level support situations, as in a table or the like for the grill assembly when separated in addition to the noted stand up mode. In other words, the dual mode capability of a preferred embodiment of the present invention makes for a highly versatile, mobile grill well suited for picnic table support or other typically preferred smaller grill settings as in tailgate events, campgrounds, and beach usage, while the other mode provides a more sedimentary, generally non-mobile assembly (outdoor deck, poolside, or backyard for repeated usage at a common position).
One embodiment of the present invention includes coupling means for releasably coupling the grill assembly and support stand, as in a telescoping relationship with a projection on one and a caption recess in the other which preferably has a slide contact relationship and matching peripheral shapes to avoid wobbling of the grill assembly when installed on the support stand. A preferred embodiment also includes means for releasably securing the grill assembly to the support stand once coupled. The means for releasably securing preferably includes non-tool release securement means (as is preferably true for the coupling means) with one example being a releasable securement assembly with a first securement component on one of the grill assembly and support and a second securement component on the remaining one of the grill assembly and support. As one example, there is provided a latch on one of the two and a catch receptor on the other of the two, as in one or more over-center latch devices. For example, in a preferred embodiment a pair of opposing (e.g., diametrically on opposite side walls) latches are provided on the support stand and a corresponding number of capture recesses are provided or supported on, for instance, the base housing of the grill assembly, as in the aforementioned coupling projection, for engagement by the latches and releasable securement of the grill assembly to the support stand. Use of more permanent securement means (e.g., tool required fasteners) is also featured under another embodiment of the present invention, either alone or as a supplement to the non-tool embodiment. For example, dual tool and non-tool securement means may be provided as when extended periods of usage in assembled condition are anticipated (pre-purchase, storage, shipping, etc.), while periods of dual use are also contemplated. However, a preferred embodiment features a non-tool, hand releasable (and preferably also hand securing) securement assembly with one embodiment featuring the aforementioned latch arrangement, and other examples including thumb screw fasteners, grasping handle/bolt combinations, spring biased extension pins, circular rotating latch and clasp assemblies, combinations of the above, etc. As an additional example, in one embodiment there is provided a plurality of thumbscrews (or, as another example, threaded fasteners with associated turn handle) which extend into aligned apertures formed in mating or adjacent surfaces (e.g., three side as in the two sides and rear) of the respective grill assembly and support stand reception section.
As previously indicated, the grill assembly is preferably of a “ready-to-use” type once removed from the support stand and upon completion of any associated expansion or component manipulation between a support stand reception position and grill assembly stand alone position. As one example, a grill assembly of the present invention includes a leg assembly, which is preferably a collapsible leg assembly, that collapses into a support stand reception mode which facilitates coupling of the combination via the coupling means and, upon removal from the support stand, is manipulatable into a self support mode which can be carried out with minimal operator assistance, as in pulling, turning, shifting, etc. of one or more components of the leg expansion assembly. Alternatively, such action is either facilitated or replaced with an automatic manipulator means, as in a device for automatically affecting expansion or movement of the grill assembly self support components upon removal of the grill assembly form the reception area of the support stand. For example, in one embodiment of the invention there is featured a collapsible leg assembly with spring bias which biases the grill assembly into a leg expansion state and helps retain that state. However, such an arrangement can make support stand insertion and attachment more difficult for the operator who has to work against such an automatic expansion device (at least until a collapsed leg latching device can be implemented (e.g., a spring biased pin supported on a slide post that can retain a sliding ring in a collapse mode until released in umbrella like fashion)). Accordingly, an embodiment of the invention includes a device that can be easily manipulated by an operator to adjust the grill assembly from a collapsed storage state to an expanded self support stand alone state which is free of any position biasing device.
In one embodiment, the contraction/expansion leg assembly comprises a bottom post, a spoke like lever assembly, and an adjustable leg set. For example, there is featured a lever assembly that includes a slide ring slideable along a post extending from or below a lower bottom housing of the grill assembly. Also, star extension levers or link members are circumferentially spaced about the ring and pivotably and/or slideably attached thereto, and the outer ends of the levers are pivotally and/or slideably attached to intermediate portions of support legs that extend down from the lower region of the grill assembly. The upper ends of the stand alone grill assembly legs are preferably pivotally and/or slideably secured to a base region of the grill housing assembly and provide support to the grill assembly cooking enclosure and fuel and/or heat supply means if present when in use. The legs preferably diverge outwardly in going down from the bottom of the base housing of the grill assembly and are of a length and number (e.g., a single one with largely enlarged footprint (e.g., a shorter sub-pedestal arrangement), preferably at least two legs (with intermediate and large footprints), and more preferably three, four or more legs) to provide a stable platform for the grill assembly when separated from the support stand. In one embodiment of the invention, the free ends of the legs (which preferably are flat bottomed, expanded regions of the legs) extend out to a radial intermediate region between the central vertical axis of the grill assembly and the direct down shadow edge of a peripheral edge of the grill's base cooking enclosure housing and more preferably radial out to that peripheral edge or radially beyond, as in radially 25 to 50% farther out from the outer shadow edge location of the base housing.
Thus, in use, when the grill assembly is removed from the support stand, the sliding ring (the ring and post preferably being circular in shape but other configurations are also possible, as in matching polygonal configurations) slides or is slid down along the slide post taking with it the connected interior link members which cause the legs to expand out as the link members go from a more vertical state to a more horizontal state. As one example, the outward extension of the link members cause the legs to adjust from an initially vertical or close to vertical collapsed state to an expanded downward and outward sloped grill support state. Preferably the full expansion state of the legs puts them at about a 30 to 60° (e.g., 45°) slope arrangement and also places the legs in a temporary lock-out state, as in each link member of the spoke link arrangement being moved to a generally horizontal and/or straight line status which locks out the legs in their expanded state, particularly with the weight of the base housing on the outwardly sloping legs. The slide post is thus preferably made to accommodate a sufficient slide range in the ring to achieve that temporary lock out state in the leg support levers, with preferably a degree of additional downward extension in the slide post to avoid undesirable release. Alternately, there is featured a post cap placed at the lower end of the post to lock on the ring.
The grill assembly also preferably has a main base housing well suited for encompassing a heat source or heat supply means as in a gas burner, an assembly of briquettes, coal, wood, electric heater units, etc. In one embodiment a gas burner is provided as in a propane burner head which is supported within the interior of the main base housing as the heat supply means. The gas burner is in gas flow communication with gas line conduit(s) that work in conjunction with a fuel source supply means, as in a propane tank. The grill assembly main base housing also preferably provides support to the gas supply lines and a gas and air flow control device (e.g., valve). In addition, the base housing also preferably supports a lid as in an integrated (rotatably attached) lid, although a completely removably lid or cover is also featured under the present invention. An additional embodiment includes a flame disk insertion with reference being made to U.S. Pat. No. 6,012,382 sharing at least one common inventor with the present case which illustrates various flame disk embodiments and is incorporated by reference, as well as a base pan insert as in one of the base pans described in U.S. Pat. No. 6,029,566 also sharing at least one common inventor, and which is also incorporated herein by reference. The present invention further includes additional improvement in its flame disk and base pan configuration which is well suited for cooking waste removal and high efficiency heat dissipation. A suitable grill rack is also sized for support within the base housing.
As noted above, a preferred embodiment features a cooking apparatus which comprises a ready to use grill assembly which has the same assemblage of components within the support stand support mode as it does in the separated from support stand, self standing self-supporting mode. In one embodiment of the invention there is provided gas fuel supply assembly which is associated with the grill assembly such that the same gas supply supply and control system is utilized both when the grill is in support stand mode and when on its own. For example, a gas control knob with gas valve associated with it is featured in one embodiment to provide variations in the fuel/oxygen(air) mix being fed to a burner head in the base housing (e.g., a cyclone burner). Furthermore, there is also preferably included a gas connection device that utilizes a gas (or in-feed) line (e.g., flexible intermediate gas line) with gas canister connection free end, or a gas canister by itself connected directly to a burner in-feed line. A flexible gas line is connected in one embodiment at one end to a more rigid grill assembly (e.g., the grill base) supported burner feed line and has an opposite end suited for connection with a gas source as in a 20 lb propane tank or a smaller embodiment, as in a 1 LP gas cylinder. The gas connection between the gas source and burner head preferably includes a grill mounted gas supply pressure regulator to which is either attached the intermediate (e.g., flexible) gas line or the gas canister directly due to a common thread arrangement. In addition, relative to the gas supply means, there is also preferably provided, in gas communication with the burner head, a relatively rigid supply line that extends out from the main grill housing and includes, for example, the noted intermediate gas line functioning as a propane tank hose line attachment means for use with a 20 lb LP (9.09 kg) gas cylinder supported on the ground or like and positioned a distance away from the support stand. In an alternate embodiment a smaller gas container is provided, as in a 1 lb LP gas cylinder, that can be attached directly to the rigid supply line device (e.g., to a threaded port in the regulator) so as to have the gas cylinder supported/suspended off the ground by way of its connection to the preferably rigid supply line device (with or without additional support features such as a holster support or platform supported on the support stand).
This direct connection of a smaller gas supply canister is also preferably applicable to the grill assembly alone mode, and, in a preferred embodiment, the supply line device is connected to a part of the grill assembly so the entire supply line device goes along with the remainder of the grill assembly upon removal of the grill assembly from the support stand. In view of the removed grill's typical mobile nature, the use of the 1 lb canister is deemed to be a desirable combination in that the small canister is sufficient for most remote cooking usages and is easily mobile like the grill itself. In the small canister use embodiment, it is possible to use the gas canister while in the support stand and then remove both the grill assembly and attached canister away from the support stand while keeping the combination of the grill assembly and gas supply container together during the transport to a location remote from the support stand. This facilitates ease of use in going from one mode to the other in that the gas supply remains unaffected during removal and movement away from the support stand.
A preferred embodiment of the invention also preferably includes a drip reception collector, as in a drip tray with a preferred embodiment featuring a drip tray that is supported by a component of the grill assembly, as in a slideably supported tray supported at the lower region of the housing. In one embodiment there is provided a telescoping bottom portion of the telescoping projection of the base housing designed to nest within a reception area of the support stand. The drip collector is preferably supported so as to be adjustable between a storage state (e.g., a slid in state) wherein it does not interfere with the insertion of the grill assembly into the support stand, while also being adjustable to a collector opening access state to facilitate removal of collected material (e.g., a sliding drawer arrangement as in one with complete slide out freedom or a stop with or without additional multi-positioning capability as in the freedom to pivot into a dumping orientation following assuming a slide out state.)
The present invention also features a waste (e.g., grease) flow (includes falling solid material and/or liquid flow material) dispensing arrangement which facilitates the capture and removal of grilling waste, as in grill food components, ash, etc., in conjunction with the noted drip tray. To facilitate the grease flow dispensing the dispensing arrangement of the grill assembly is self contained relative to the removable grill assembly, and thus avoids involving or contaminating the support stand. That is, there is avoided a high degree of pedestal cleaning requirement. The grease flow dispensing arrangement includes a flame disk having a main body that is preferably horizontally planar and has a downwardly curving peripheral end (preferably continuously all around the periphery, although only some of the sides (if multiple sides involved) is also featured under the invention). Preferably the downward flange portion of the flame disk extends essentially about the entire periphery (e.g., 85 to 100%) as it facilitates heat retention relative to the heat source below. The flame disk also preferably has tear dropped shaped apertures covered over by uplifted covers to provide efficient heat dissipation and with the covers providing protection from grease falling within the center area of the grill assembly, which is less suited for waste removal.
The grease falling from the flame disk falls into a base pan having an enlarged, centralized interior aperture through which extends a burner head and/or through which flows heat from a heat source below (gas head, fuel briquettes, etc.) and which is surrounded by an upstanding flange member which helps capture grease between that flange and an outer slopping wall extending up off the intermediate floor region of the base pan. The base pan has a slight slope down from (e.g., 10° or less, as in 2 to 5°) with a smaller drain aperture provided within the intermediate floor region and preferably closest to the lower most portion of the intermediate floor region (e.g., the drain aperture having an edge coincident with the border edge between the base pan's shaped outer wall and its floor region or just inward by 5 inches or less). Thus, any grease dripping off the flame disk will first be captured between the flange defining the central burner head reception aperture and the outer sloped wall of the base pan (which outer wall can also function to direct grease down to the intermediate floor region). Further, any grease received by the intermediate floor region is directed under the force of gravity toward the lower positioned drain aperture. The floor region described herein can also include, for example, a continuation of the outer wall region, as in the lower half of a semi-circular base pan with the aperture then preferably moved closer to the central aperture flange, although a preferred embodiment features an intermediate floor region made distinct from the side wall, as in the aforementioned planar, sloping downward intermediate floor with corner break leading into the upwardly extending wall region of the base pan (e.g., the more radially outward positioned drain apertures facilitate maintaining the grease away from the burner head or other heat source more centrally positioned and, as explained below, provides for usage of the grill base configuration to help channel grease into a desired location relative to the drip pan).
For example, in one embodiment, the base pan is positioned (e.g., suspended) above the bottom floor of the grill base (e.g., above the gas flow piping and ignition components, if gas flow is involved) and has means for receiving and directing waste into a desired feed location relative to an aperture in the grill base bottom leading into the receiving cavity of the drip pan, as in a sloping side wall section that is integrated with an edge of a receiving cavity for the drip pan which can be, for example, a corner edge of the drip pan and/or the grill base's floor aperture. For example, a welded or otherwise fixed ski-slope insert for directing grease falling from the (with or without confined upper extending side edge walls) base pan grease aperture or an integrally formed section of the grill base itself (e.g., such as a punched in section via a die or original molding pattern) can be utilized, which is either planar or has a slight concave cross-section to facilitate flow directing. The sloping nature of the receiving and directing means and its relative positioning to the grease aperture provides for, with the assistance of gravity, all of the grease captured in the base pan to be properly focused and directed into the drip tray to avoid waste build up or contact with other less desirable areas. The receiving and directing means thus directs the grease dripping out of the grease aperture into the desired receiving location in the drip tray, where it can be readily discarded once sufficient build up has occurred, simply by sliding or otherwise removing the drip tray from the drip tray receiving aperture provided in the grill assembly. Furthermore, this waste capturing arrangement is self contained in the grill assembly and fully functional in both the combination mode and the grill assembly stand alone mode, and preferably is provided with a pull out handle.
