Description

FIELD OF THE INVENTION

The present invention relates to cooking devices or apparatus, and more particularly to an apparatus for the cooking or grilling of meat.

Cooking grills of various types are of course well known; and thus the present invention is just to concepts of certain details of the overall apparatus and to its combination of features and details as will be apparent as described herein.

SUMMARY OF THE INVENTION

According to the present invention, a horizontal grill-support arm is connected to a vertical support post, which is itself connected to a base, all the connections being adjustable, and the connection between the support arm and support post is further movable in that it accommodates the horizontal arm to revolve; and to effect the revolving, there is provided both a hand crank and a motor giving a rotisserie operativity of either powered or non-powered nature.

The horizontal arm is provided with a movable grill, which itself is formed of movable sections, providing that the grill may be used in an opened or flat-out condition for maximum area, or a folded over condition for clamping meat when using the device as a rotisserie.

These and other features, and their advantages and details, will be more apparent as the description proceeds.

The prior art does not show the inventive concepts, even though the cooking mechanism art is quite ancient, including grills for outdoor use

The prior art of cooking and cooking by grills is no doubt one of the most ancient as to use and development; and the prior art for equipment in this realm has long provided various modifications; and, since it has been long known that cooking procedures, specifically including the grilling of meat, encounter a variety of heating situations, with outdoor cooking particularly being non-uniform, the prior art has provided not only a variety of cooking and grill features and arrangements but also has utilized a variety of concepts of adjustability and optionality of use.

And since cooking and grilling procedures are quite basic to human life, and since the acts of cooking and grilling meat are such easily-observed procedures, and since most all persons have personally participated in cooking and grilling, the prior art non-origination of particularly the present combination of concepts and features is realistically to be recognized as more non-obvious than improvements would likely be in most other fields of endeavor.

With this background, the significance of the combination of concepts of the present invention, by which the user is provided with an effective, economical, and practical grill device, having considerable optionality of use for accommodation of diverse cooking situations, is better to be evaluated as to relative advantages and non-obviousness of the inventive concepts.

In a hindsight consideration of the present invention's concepts to determine its inventive and novel nature of the invention as a whole, it is not only conceded but emphasized that the prior art had multiple details of support, adjustability, etc., which would have been usable in this invention, but only if the prior art had had the guidance of the present concepts of the present invention; and the prior art for centuries had much motivation as to grilling apparatus of the present invention.

That is, it is emphasized that the prior art had several particulars of prior art and motivation which individually and accumulatively show the non-obviousness of this combination invention as to its various features:

Supports; slidable supports; adjustments; hinges of various kinds; upright stands; bearings providing both support and rotatability; etc. Such mechanisms, of various types, are devices which are of ancient use and knowledge, even adjustable supports in cooking and grill apparatus; and such and similar devices including specifically those for cooking apparatus, have been used by all or an untold numbers of persons, the world over.

Further non-obviousness of the invention as a whole is shown by the fact that support mechanisms having considerable adjustability have been provided in specifically meat-grilling equipment.

With the reality of all these factors, the inventive non-obviousness of the present invention is quite manifest.

The prior art has had features of the present invention, and approaches to its concepts, but not in the combination by which the invention as a whole is advantageously achieved

The background of prior art as just summarized seems more significant in showing the nonobviousness of the present concepts when also it is reminded that the prior art also had long provided long and used principles of support and adjustability for accommodation of many types of devices, and the prior art long realized that adjustability was quite desirable in devices for cooking and grilling; and metal-shaping and metal-forming and other manufacturing procedures are well known by which all components of the present invention could have been made, if the prior art had had the specific concepts of the invention.

And the existence of such articles embodying such various features is not only conceded, it is emphasized; for as to the novelty here of the combination, of the invention as considered as a whole, a contrast to the prior art helps show both the great variety of the various prior art attempts of improvement, and the advantages and the inventive significance of the present concepts. Thus, as shown herein as a contrast to all the prior art, the inventive significance of the present concepts as a combination is emphasized, and the nature of the concepts and their results can perhaps be easier understood.

Although varieties of prior art are conceded, and ample motivation is shown, and full capability in the prior art is conceded, no prior art shows or suggests details of the overall combinations of the present invention, as is the proper and accepted way of considering the inventiveness nature of the concepts.

That is, although the prior art shows an approach to the overall invention, of adjustable cooking devices, and the prior art has shown various natures of supports and adjustability, it is significant that none of the prior art shows the novel and advantageous combination, which provides the merits of this invention, even though certain details are shown separately from this accomplishment.

Accordingly, the various concepts and components are conceded and emphasized to have been widely known in the prior art as to various devices; nevertheless, the prior art not having had the particular combination of concepts and details as here presented and shown in novel combination different from the prior art and its suggestions, even only a fair amount of realistic humility, to avoid consideration of this invention improperly by hindsight, requires the concepts and achievements here to be realistically viewed as novel combinations, inventive in nature. And especially is this a realistic consideration when viewed from the position of a person of ordinary skill in this art at the time of this invention, and without trying to reconstruct this invention from the prior art without use of hindsight toward particulars not suggested by the prior art of all relevant fields.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENT:

As shown in the drawings, the overall combination is a grill device or apparatus 10, providing a multiplicity of adjustment features.

Its general features as most apparant are a supporting base 12, a support post 14, and a support arm 16. Their function and co-operative utility of supporting a piece of meat 18 above a heating fire 20 will be apparent from the drawings, as will their adjustability and other special features.

An adjustable connection, here called a first connection means 22, supportingly connects the support post 14 to the base 12; and the significance of the adjustability of that connection 22 will be apparent below.

A second adjustable connection, here called a second connection means 24, supportingly connects the support arm 16 to the support post 14; and ts adjustability and nature will also be shown below.

A grill body 26, on the support arm 16, is held by a third adjustable feature, here designated as a third connection means 28, which supportingly connects the grill body 26 to the support arm 16; and of course the direct support of the meat or other cook-item 18 is the grill body 26.

The description now turns to features of adjustability.

The first connection means 22 is to be noted as substantially spaced from a stability-portion 30 of the base 12 which is generally under the support arm 16, such that the support post 14 is stably supported, i.e., supported to be held operatively upright even though the weight and distance from the second connection means 24, of all of the support arm 16, the grill body 26, and the meat or other cook object 18 being carried by the grill 26, are such as to create a moment-arm effect which might or would topple the support post 14 from its upright position.

This feature of operatively upright support is achieved by the counter-balancing supportive effect of the above-mentioned spaced or stability-portion 30 of the base 12 engaging the ground with enough moment-arm effect of its own to offset the moment-arm effect of the support arm 16, grill body 26, and cook object 18.

As to the benefit of adjustability of the first connection means 22 as to the base 12 and support post 14, those two components (base 12 and post 14) may be supportingly connected in optional orientations; this provides that even though one orientation may be optionally such as to provide that the spaced portion 30 of the base 12 provides the counter-balancing moment-arm supportive effect mentioned above, the orientation also may be optionally a second orientation (chain lines) such that the stability-providing or spaced portion 30 may be given its counter-balancing moment-arm supportive effective by a log or other external wreight, or the like as an associated force means 32 with the stability-providing or spaced portion 30 of the base 12 removed from the position of the associated heating means 20 generally under the support arm 16, thus achieving device-stability but without the base-portion 30 being in or made dirty or ash-covered by the fire 20.

As to the second connection means 24, one of its features is that it provides optionality of height, i.e., the user's option as to how high above the base 12 it is that the support arm 16 is supported, thus how high the grill body 26 and meat 18 are spaced from the fire 20. Thus, it is shown with a bolt 34 threaded into a hole in the casing 36 of the second connection means 24, engageable firmly onto the post 14.

Not height-adjustment is a feature of the second connection means 24, however; for in its role of providing support of the support arm 16 by the support post 14 it permits the support arm 16 to be revolved while being supported by the second connection means 24. Thus the second connection means 24 and its overall casing 36 provides a horizontal bearing 33 for rotatable support of the support arm 16.

The support arm 16 is further noted as provided with an extension 40, it being located oppositely from the grill body 26, i.e., when the support arm 16 is supportively connected to the support post 14, by the second connection means 24, the support arm extension 40 is on the side of the second connection means 24 which is opposite to that to which the grill body 26 is connected to the support arm 16 by the third connection means 28.

As to provisions for rotisserie effect, there is provided a crank handle 44 and a motor 46, each with means connectable to the said support arm extension 40 for optional use in causing the rotisserie or revolving effect of the support arm 16 and grill 26.

There is provided for the motor 46 not only means connecting the motor 46 to the support arm extension 40 for causing a revolving effect of the support arm 16 and grill body 26, but motor-support means here shown as a brace 50 connectable to the motor 46 and support post 14, respectively, for supporting the motor 46 while it causes the revolving effect to the support arm 16 and grill 26 with the meat 18 clamped thereon.

When rotisserie effect is not desired, the revolvable support arm 16 is held against inadvertent revolving by blocking means, i.e., a means which is regulatable to provide the option of the support arm 16's revolvability or blockage against revolving, that blocking means being here shown as a bolt 51 which is threaded into a hole of the casing 36's part 33, and firmly engageable onto the horizontal support arm 16.

Adjustability and optionality is also provided for the grill body 26. As shown, grill body 26 is provided to be formed of at least two relatively movable body members 26a and 26b, with hinge means 52 movably interconnecting the two body members 26a and 26b of grill unit 26. The hinge 52 is shown as a pair of rings loosely interconnecting the grill bodies 26a and 26b.

This relative movability of the grill 26's two body members 26a and 26b permits an end-to-end arrangement thereof on the support arm 16 (FIG. 1) for relatively maximal support-area for cook objects 18, but also provides them to be able to be put in a relatively juxtaposed arrangement (FIG. 3) for supporting both sides of a cook object 18 when the support arm 16 and the grill body 26 are being revolved as in rotisserie effect.

Further, adjustability and optionaly is provided for the overall grill body feature 26. That is, the third connection means 28 is connected to a first one (26a) of the grill's body members, and the second one (26b) of the grill's body members is provided with a pin 54 adjacent the end 56 of the second grill body member 26b which is remote from the hinge means 52, and the support arm 16 is provided with a hole 58. Further, the second one (26b) of the grill body members is supported when in its end-to-end arrangement of the grill 26 by the presence of the pin 54 in the hole 58 and by the hinge means 52 connection of the two grillk body members 26a and 26b, and by the third connection means 28's connection to the first grill body member 26a and the support arm 16.

It will be further noted that the grill body member 26b, that being the grill-body which is the one non-adjacent the horizontal support arm 16 when the two grill body members 26a/26b are in their relatively juxtaposed arrangement, i formed of expand metal 60 of a diamond nature, and more particularly being more flexible in one direction than the other, and the grill body member 26b is provided from such material by a piece thereof in which the direction of more flexibility is perpendicular to the hinge means 52, thus accommodating a relatively easy bending thereof along lines parallel to the hinge means 52 to accommodate without undue mashing meat or other cook objects 18 when held between that that grill member 26b and the other grill member 26a, while that grill member 26b is resiliently deformed over the cook objects 18 in being firmly connected to the other grill member 26a in their clamped, juxtaposed arrangement.

Both grill bodies 26a and 26b are shown of expanded metal.

The skewers 62 are each slidably held onto the support arm 16 by holding bodies 64 which are parts of the third connection means 28, and held by thumbscrews 66; and adjustability along the support arm 16 is provided by an elongated flat 68 extending along substantially its full length, the flat 68 being a cutaway feature accommodating the thickness of the skewer rods 62 in offset holes 70 in the wall of the holding bodies 64 without need of extra looseness or extra size of those holding bodies 64, which are shown as economically formed from standard symmetric cross-section stock here shown as being square cross-section, just large enough to freely be assembled onto the support arm 16.

The cutaway nature of the flat 68 also accommodates the thickness of the holding pin 54 at the end 56 of grill body 26b when that pin 54 is used to clamp the grill bodies 26a and 26b in their juxtaposed condition (FIG. 3) by being inserted (FIG. 3) in an offset hole 72 (hidden in FIG. 3 but shown in FIG. 1).

That hole 72 is in the holding body 64 which is connected as by weld 74 to the end 76 of the grill body 26a which is the grill body end 76 which is remote from the end 78 of the grill body 26a which is shown connected as by weld 80 to a holding body 64 (as shown in FIG. 3) in the region of the hinge 52.

The holding bodies 64 of the third connection means 28 may be of various lengths, as indicated in the drawings. Thus, e.g., the holding bodies 64 of FIG. 4, which hold the skewers 62, are shown as relatively shorter than the holding bodies 64 of FIGS. 1 and 3 which illustrate connection means 28 which connect the grill 26 (26a and 26b) to the horizontal support arm 16, by welds 74 and 80 of the grill body 26a.

The first connection means 22 and the portion 82 of the second connection means 24 (which is the body-portion 36 which is the portion assembled vertically onto the vertical support rod 14) are also shown as formed of material from square cross-section stock. The body 22 is shown as welded at 84 to the base 12; and the body 82 is shown as welded at 86 to the support body 33. All of the connection means are shown as having screw-type clamping means, providing tight yet releasable connections as shown.

Preferably, the various parts or components of the overall invention are provided in kit form; and with the first connection means 22, the second connection means 24, and the third connection means 28 all being of releasable nature, this provides not only the advantage of marketing of the overall device 10 in knocked-down or kit form but accommodates convenient disassembly for ease of cleaning and storage.

SUMMARY OF OPERATIVITY:

The various features of adjustability and optionality of positioning of the parts, as already described as to particulars, give many options:

a. Relative orientation of base 12 and post 14; and of base 12, and arm 16 and grill body 26;

b. Relative heights of arm 16 and grill 26, as to post 14 and base 12;

c. Revolvability or fixed nature of arm 16 as to the post 14;

d. Crank or motor for rotisserie effect;

e. Use outdoors and with various indoor heating provisions;

f. Various relative positions of grill-bodies for maximal object carry, or for clamped-portion positioning for rotisserie use.

g. All easy to assemble from kit form, and easily to quite fully dis-assemble as for cleanup and storage.

CONCLUSION:

It is thus seen that a grill device, especially in kit form, as provided and used according to the inventive concepts herein set forth, provides novel concepts of a desirable and advantageous device, yielding the advantages of an overall grill assembly having advantageous details and features, which, in overall combination, is and are conceptually different from the prior art grills even though various objects embodying certain of the mechanical details as a basic capability have of course been known for years; yet significantly this particular conbination, even considered as including or building on prior art concepts, has not been suggested by the prior art, this achievement being a substantial and advantageous departure from prior art, all this even though the prior art shown attempts at improvement and variations as to grill devices and other cooking devices for many years, including cooking grill units for outdoor use. Ane particularly is the overall difference from the prior art significant when the non-obviousness is viewed by a consideration of the subject matter as a whole, as integrally incorporating a combination of features as different from the prior art, in contrast to merely those details of novelty themselves, and further in view of the prior art teaching away from the particular and inter-related concepts and features of the present invention.

In summary as to the nature of these advantageous concepts, their inventiveness is shown by novel features of concept and construction shown here, in novel and advantagous combvination, not only being different from all the prior art known, but because the achievement is not what is or has been suggested to those of ordinary skill in the art, especially realistically considering this as comprising components which individually are similar in nature to what is well known to makers and users of grills and other cooking devices for many years. No prior art has suggested the modifications of any prior art to achieve the novel concepts here achieved, with the various features providing their own functions in the overall combination; and this is particularly significant since cooking devices are probably in the oldest field of art ever known, and because cooking grills are objects whose mechanisms are easy and apparent to observe, and have been no doubt observed by most all persons the world over, for all ages.

Accordingly, it will thus be seen from the foregoing description of the invention according to this illustrative embodiment, considered with the accompanying drawings, that the present invention provides new and useful concepts of a novel and advantageous grill device or apparatus, having and yielding desired advantages and characteristics in formation and use, and accomplishing the intended objects, including those hereinbefore pointed out and others which are inherent in the invention.

Modifications and variations may be effected without departing from the scope of the novel concepts of the invention; accordingly, the invention is not limited to the specific embodiment, or form or arrangement of parts herein described or shown.
