Food supports per se are well known from the prior art and may be in the form of sheets, grills, cushions or the like. For this purpose, they can be made of different materials, wherein in particular the use of aluminum is preferred because of the good thermal conductivity of this metal. In order to prevent adherence of food to be cooked on a food support, for example, its coating with silicone, Teflon or enamel coatings is known.

That's how it describes DE 297 09 500 U1 a cooking container made of aluminum or an aluminum alloy, which is coated with an aluminum enamel. Also from the DE 195 27 360 A1 a food support is known, which has a base body having aluminum with a protective layer of an aluminum enamel, wherein between protective partial areas also open spaces for forming heat access windows can be provided on the underside of the food support.

From the DE 102 21 471 A1 a food support with a support member is known, which has a rib structure on one side for increasing the heat input into a food. unilaterally profiled Gargutträger are further from the GB 2 406 489 A1 , of the WO 2005/030020 A2 , of the DE 199 06 181 A1 , of the DE 200 21 892 U1 and the US 4,603,052 known.

Numerous of the food supports also have openings for improving air circulation, wherein here, by way of example, again on the GB 2 406 489 A , the WO 2005/030020 A2 , the DE 200 21 892 U1 and the US 4,603,052 in addition to the DE 197 50 488 A1 as well as the DE 197 50 486 A1 to indicate.

From the US 5,938,968 For example, a telescopically extractable food support from a microwave oven is known which has a gripping device in the form of a recess.

Buderus AG has distributed in the Juno division an oven under the trade name Convectomat®, Junior S, in which a food support consisting of a cast plate with two different sides was used as an accessory, namely with a side of pizzas which had recesses, and a roast side that had elevations. To carry this Gußplatte a handle was provided which was releasably pluggable via two pins in two openings of the cast plate.

The DE 298 02 388 U1 discloses a tray made of plastic for baked goods with a bottom and an at least partially encircling edge, wherein the tray is formed of an upper and a lower shell, and the shells are at least locally firmly connected to each other at the edge and touch the ground in places.

A gattunsgemäßer food support is from the US 5,938,968 as particularly easy to insert into a microwave oven insert known.

Despite the great variety of previously known Gargutträgern there is still the need for a simple and robust structure, which ensures improved handling of such Gargutträger, during storage and also during insertion and withdrawal from the cooking chamber of a cooking appliance. This food support should also provide improved heat absorption and heat transfer and be inexpensive to produce.

It is therefore the object of the present invention to develop the generic food support such that it overcomes the disadvantages of the prior art.

This object is achieved by the features of the characterizing part of claim 1.

It can also be provided that the base body has a plurality of holes.

With the invention it is also proposed that the base body in the form of a grid and / or a support formed and / or rails in a tray rack, oven rack or Einhängegestells is inserted, preferably either in the transverse slot or in the longitudinal slot, in the transverse slot, the transverse sides of the body in Rails are feasible and in the longitudinal insert the long sides of the body can be guided in rails.

According to the invention, it is preferred that the gripping device comprises at least one recess in the base body.

It can be provided that the recess is at least partially, preferably completely, limited by a third edge on the side of the body with the profiled surface in the form of an increase.

Particularly preferred embodiments of the invention are characterized in that a first handle of the handle device is provided by the recess itself, and / or a second handle of the handle device is provided by a member fixed or attachable in at least one recess.

It can be provided that at least a first and / or at least a second handle on at least one transverse side and / or at least one longitudinal side of the body is or can be provided.

Furthermore, it can be provided that each recess for providing a first handle has substantially the shape of a rectangle or oval.

According to the invention, it is particularly preferred that the member of the second handle comprises a bracket, in particular a wire bracket, the free ends of which are preferably fixable in each case in a recess, in particular releasably.

It can be provided that two recesses for securing a bracket form a pair of holes.

Furthermore, it can be provided that the bracket with the main body is selectively either from the side with the profiled surface or from the side with the smooth surface extending releasably connectable away.

The invention also embodiments are proposed, which are characterized by a stop member, the same when pulling out of the body of a tray rack, oven rack or suspension frame against this, especially against a vertically extending post, before the body, the rack frame, the oven rack or the Hanging rack leaves, wherein the stop member is preferably provided by the handle device, in particular the second handle.

Furthermore, it can be provided that the first and / or third edge is lifted or lifted off a smooth area of the side of the main body with the profiled surface.

It is also proposed according to the invention that the first edge extends away from the base body beyond the elevations of the profiled surface and / or beyond the third edge.

The invention also provides a kit comprising a plurality of basic bodies and gripping devices for assembling at least one food support, wherein the food support and an inventive product support is formed and the base bodies are stackable on each other by a first edge of a base body engages in a second edge of a base body adjacent thereto.

It can be provided that at least a second handle on a base body either in the edge region of its transverse side or its longitudinal side is at least temporarily fastened, preferably optionally wegerstreckend from the side of the body with the profiled surface or the side of the body with the smooth surface.

The invention is therefore based on the surprising finding that a versatile food support, for example, by placing a first food on a profiled surface for grilling or by placing a second food, such as pizza or the like, on a smooth surface for baking is used , Having a plate-shaped base body which presents on two opposite sides, on the one hand, the profiled surface and on the other hand, the smooth surface and is connectable with a handle device that food can be placed either on the profiled surface or the smooth surface, while simultaneously stacking such body to each other is possible by an increased first edge, preferably along the entire circumference of the base body is provided on the side with the profiled surface, while on the side with the smooth surface, a second, recessed edge, preferably along the entire Scope of the body, is provided so that in adjacent bodies each engage an elevated first edge in a recessed second edge. This intervention also ensures that when stacking the body adjacent profiled and smooth surfaces do not scratch each other or a stack falls over, which ensures a long shelf life of the food support according to the invention as a whole. The raised edge on the side with the profiled surface also serves as a splash guard, which prevents it when removing a food support from a cooking chamber to injuries with hot oils or fats.

It also comes with a food support according to the invention to increased heat absorption from a cooking chamber atmosphere over the profiled surface, especially when the food is positioned on the smooth surface, while increased heat transfer from the food support to the food takes place when the food is positioned on the profiled surface is. As a result, shorter cooking times or lower cooking temperatures can be used, which results in particular in a cost reduction. It has been found that the use of food carriers according to the invention leads to excellent baking, roasting and grilling results leads. This is essentially due to the fact that at least one side of the food support has spaced-apart elevations to increase the surface area. These elevations are preferably carried out in the form of ribs, waves or corrugations; However, it is readily apparent to one skilled in the art that surveys of various shapes can be used, which lead to a very uneven side and improve the heat absorption of the food support. For example, straight, cross-shaped or diamond-shaped corrugations are conceivable. As surveys and cylinders, bolts and / or Wärmeleitbleche come into consideration.

By an enamel coating of the aluminum body of a preferred food support according to the invention not only a good heat conduction is ensured, but it is also, due to the very smooth and extremely hard surface of the enamel coating, an adhesion of the food to the food support prevented. When using an enamel coating, baked foods can be easily removed with abrasive cleansers or scratched without damaging the enamel coating. Furthermore, the enamel coating is food-safe and can be used permanently up to temperatures of 300 ° C.

In the food support according to the invention, at least the gripping device is provided on at least one edge region of the base body. This gripping device can be designed as a handle which protrudes, for example, from the plane of the base body. In this case, however, the handle must be made detachable from the body so as not to be in the way of stacking of bodies. For this purpose, the base body preferably has pairs of holes, in which free ends of a wire bracket can be fixed. In this case, a plurality of pairs of holes can be provided in the edge region of the base body, so that a wire hanger is selectively fastened to the side of the profiled surface or the side of the smooth surface, be it on a longitudinal side or a transverse side. Of course, several such handles can be provided. Particularly preferred is the alternative design of the handle device in the form of a recess that can be used as a carrying handle or for easier removal and insertion of the food support in the oven.

A around each hole of the hole pair or the recess around arranged, protruding from the side of the food support with the profiled surface edge can also prevent the food falls through a hole or the recess. But also oils and fats will Droplet drops from the food support in the area of the hole pair or the recess blocked. Rather, holes can be provided for targeted drainage of oils and fats, which can also lead to a reduction of smoke in the oven.

In a preferred embodiment, the food support according to the invention may be in the form of a perforated plate, depending on the intended application. Of course, even with a perforated plate one side thereof may be provided with elevations.

A designed as a handle wire bracket can inventively also act as a stop member by the wire hanger namely when using the food support according to the invention with a tray rack, oven rack or hanging rack against the latter or the latter when pulling pushes, especially against a vertically arranged support or post to which a variety is arranged by horizontally extending rails, in which the base body is movable. Thus, the handle also serves as accident prevention.

a perspective view of a second food support according to the invention;

FIG. 4

another perspective view of the food support of FIG. 3 ; and

FIG. 5

a perspective view of four food carriers according to the invention in a tray rack.

FIG. 1 shows an inventive. Food support 1 in supervision. The food support 1 is formed in the form of a substantially rectangular sheet or body 2 made of aluminum with an enamel coating. On the side of the main body 2 shown in plan view, a profiled surface 3 with rib-shaped elevations 4 is formed. These elevations 4 provide for improved heat absorption of the food support 1 from a cooking chamber atmosphere, so that the food support 1 absorbed heat better on a resting on the opposite side food (not shown) can pass. But these surveys 4 also ensure better heat transfer from the food support 1 to a resting on the profiled surface 3 food (not shown).

At an edge region 5 of the base body 21, a handle device is further shown with a recess 6, which allows a simple gripping the food support 1 for pulling and pushing the same into a cooking chamber of a cooking appliance (not shown), for example via the use of rails in the cooking chamber. Therefore, the recess 6 itself is a handle 10.

It is obvious to a person skilled in the art of cooking appliance manufacture that the formation of the spaced-apart elevations 4 as well as the arrangement of the handle device 10 can be achieved in many different ways.

FIG. 2 shows a cross section through the food support 1 after FIG. 1 , Thereafter, a smooth surface 7 is provided on the profiled surface 3 opposite side of the base body 2. In addition to the elevations 4, the base body 2 on the side with the profiled surface 3 on a raised edge 8 along its circumference, while on the opposite side with the smooth surface 7, a recessed edge 9 is provided. This edge configuration of the food support 1 according to the invention allows a simple stacking of a plurality of such food support 1, without causing the food support 1 relative to each other to slip, thus avoiding the same, especially the enamel coating thereof is avoided.

To avoid an uncontrolled dripping of oils or fats when placing food on the profiled surface 3, especially when grilling, the raised edge 8 also serves as surge protection. For the same purpose, an elevation 16 is provided around the recess 6.

The food support 1 can now be performed with its transverse side 12 or its longitudinal side 13 in rails of a tray rack, not shown.

The food support 1 can be provided by two punched-out and interconnected aluminum surfaces, with bent edge regions.

As an alternative to the food support 1 is in the FIGS. 3 and 4 a further product carrier 1 'according to the invention, which has a plate-shaped main body 2', preferably made of an aluminum casting, with a profiled surface 3 'including elevations 4' on one side, an edge region 5 'with a multiplicity of recesses 6'a-6' d has along its circumference and a smooth surface 7 'on its other side. The edge region 5 'can also be smoothly formed on the side with the profiled surface 3', apart from the recesses 6'a-6'd, which are preferably still limited by elevations 16'a-16'd. In addition, the entire base body 2 'along the edge region 5' on the side of the profiled surface 3 'surrounded by a raised edge 8'. Both the edge 8 'and the elevations 16'a - 16'd serve to prevent accidents and avoid uncontrolled dripping, especially of oils or fats. The recesses 6'a-6'd extend through the entire main body 2 ', ie as far as the smooth surface 7', which has a recessed edge 9 'along its edge region 5'. This edge structure in turn allows a simpler stacking of a plurality of food supports 1 ', wherein in each case a raised edge 8' engages in a recessed edge 9 ', without it for abutment of elevations 4' and elevations 16'a - 16'd a food support. 1 'comes with the adjacent food support 1'. For this purpose, the raised edge 8 'must be further from the main body 2' stand out as the elevations 4 'and the elevations 16'a - 16'd.

Again FIG. 5 can be seen, a handle 10 ', 11' in the form of a wire bow in two adjacent recesses 6'a and 6'b or 6'c and 6'd either and releasably fixed. For example, this detachable connection between the handle 10 'or 11' and the associated recesses 6'a-6'd makes it possible for a base body 2 'to be inserted either transversely or longitudinally into a tray frame 20 with only one handle, wherein FIG. 5 only cross-insets are shown. For this purpose, namely, a handle 10 'in a pair of holes 6'a and 6'b in the edge region 5' of a transverse side 12 'or a handle 11' in a pair of holes 6'c and 6'd in the edge region 5 'a longitudinal side 13' be introduced. Through a variety of Hole pairs 6'a and 6'b or 6'c and 6'd both along the transverse side 12 'and the longitudinal side 13' is a further flexibility in handling possible.

The handles 10 'and 11' can also serve as accident prevention by being a stop member. In FIG. 5 make the handles 10 'at the transverse sides 12' such a stop member, since they a complete withdrawal of the respective base body 2 'of a pair of opposing, horizontally extending rails 21 of the tray rack 20 by collision with a vertically extending support or post 22nd prevent. If the oven rack 20 is arranged in a cooking chamber of a cooking appliance, not shown, a complete extraction of the food support 1 'from the cooking chamber by abutment of the handles 10' on the adjacent to the door of the cooking chamber arranged post 22 is prevented.

Due to the releasable connectivity of the handles 10 ', 11' with the main body 2 'of each Gargutträgers 1' according to the invention is thus not only a space-saving stacking of a plurality of basic bodies 2 'possible, but also the use of the base body 2' with food either on the profiled surface 3 'or the smooth surface 7' and a transverse or longitudinal insertion possible.

The features of the invention disclosed in the foregoing description, in the drawing and in the claims may be essential both individually and in any combination for the realization of the invention in its various embodiments.
