The invention relates to a device for heating, in particular food by means of a solid fuel, in particular dry spirit with Aufstellfüßen and support parts for setting up a cookware, a can or the like. and a bearing surface for the fuel, which is formed as a one-piece sheet metal part, the central surface emits the bearing surface for the solid fuel and the upwardly bendable, designed as a flap carrier parts, on the ends of the cookware or the like. can be erected and further provided in the downwardly bendable, approximately trapezoidal Fußlappen with Aufstellkanten as Aufstellfüße, all lobes are integrally connected to achieve their flexibility over arranged on material galling bending edges with the central surface and the lobes on the outer edge of the central surface stem or radial order these are arranged around.

Such a device known from AT-PS 149 323 and FR-PS 366 340 is designed as a one-piece sheet-metal part, the central surface of which has upwardly and downwardly bendable foot flaps and carrier parts. It has the following disadvantages:

In order to avoid any subsequent bending during use of serving as Aufstellfüße Fußlappen and the support parts as far as possible, the sheet thickness must be relatively strong, so that this known device is relatively difficult.

When laid flat, the device has a circular contour. When turning the cloth, there is practically only a point contact of the cloth with the flat mounting pad, so that an unsafe installation of both the dishes on the support parts and the device is done on the Fußlappen. This risk of tipping is further increased by the fact that no exact turn of the lobes can be achieved because no clear bending edge of the lobes is given.

Further, from US-PS 4 100 912 a device is known, which has a beading arrangement for stiffening the lobes, but the device has only three support parts for the cookware or the like., So that a very high risk of tipping exists by the two flat connecting webs (20), the device is also very flexible and unstable, so that in particular when stirring food to be heated very high risk of tipping exists. In addition, the device of US-PS 4,100,912 has no central surface for dangerously laying fuel.

Object of the present invention is to improve a device of the type mentioned, which is of particularly light weight, and even in the use position flat shelves without special care in bending the cloth and which is flat to save space when bending back the feet and support parts ,

To solve this problem, the invention provides that the Fußlappen are trapezoidal and each outer long side serves as a straight Aufstellkante and the parallel short sides are connected to the central surface and that distributed around the circumference of the central surface of the Fußlappen and support members are arranged alternately . that furthermore the tabs are stiffened by at least one bead and this runs perpendicular to the associated bending edge and is brought close to this.

Once is achieved by the trapezoidal shape of the Fußlappen, but additionally by the arrangement of at least one bead in this that when turning the tabs can bend only at the predetermined bending edges and not over the length of the Fußlappen a bending occurs. Due to the exact bendability, which can be done without special care, it is possible to achieve exactly level installation surfaces both for the cookware on the device and for the device itself on the ground. The closed central surface of the subject invention also contributes significantly to the stability of the device. By these measures also the sheet thickness can be greatly reduced, so that a significant weight saving is achieved. Due to the stiffening by the beads, the dimensional stability of the cloth is guaranteed even with thinner sheet thickness. Further, by bringing the beads close to the bending edge, deformation of the tabs at an undesired point when the tabs are bent to the use state is avoided, so that sufficient strength is achieved despite the weight saving by reducing the sheet thickness.

Conveniently, the support members and the Fußlappen are symmetrically arranged alternately distributed on the circumference of the central surface, so that no tilting moments arise in up-mounted device.

In a preferred embodiment, four support members and four foot flaps are provided.

In order to ensure a uniform bending of the lobes from the central surface, it is provided that the bending edges and the free edges between the lobes form a regular polygon.

For a long life, the sheet metal part may be a galvanized, about 0.5 mm thick steel sheet with high bending fatigue strength.

Further embodiments according to the invention can be found in the subclaims and are explained in greater detail with their advantages in the following description: FIG. 1 shows a top view of a device and FIG. 2 shows an oblique view of the device shown in FIG. 1 in its position of use.

The device shown in Figure 1 is a one-piece sheet metal part of galvanized sheet steel of about 0.5 mm thickness of high bending fatigue strength He has a central surface (1), arranged on the outer edge via bending edges (2) tabs (3), (4) star-shaped are. A part of the tabs (3) has trapezoidal shape and these serve in the form of Fußlappen (3 ') as Aufstellfüße, wherein the longer sides (5) in their angled position of use Aufstellkanten (6) are for installation of the entire device on a non-illustrated

Footprint.

The other lobes (4) are finger-shaped support members (4 '), on the ends of which in the bent state of use a cookware od. Like. Can be placed.

In the plane transport state, the mutually facing sides (7) and (8) of the adjacent lobes (3) and (4) each extend approximately parallel to one another. The space adjoining the central surface (1) is bounded by a free edge (9)

In the embodiment, four Fußlappen (3 ') and four support members (4') distributed evenly distributed around the circumference, so that by the free edges (9) and the bending edges (2) is formed a uniform sixteen-corner.

In order to safely receive the normally tablet-like solid fuel, the central surface (1), shaped somewhat downwards, can form a bearing surface (10) for the solid fuel. This recessed bearing surface (10), as shown in the embodiment, square but also be formed with a simpler production of the tool circular.

To increase the flexural rigidity of the tabs (3) and (4), these are each provided in their middle with a bead (11) extending from the end of the flap to near the bending edge (2) so that the tabs (3) and (4) can be angled slightly upwards or downwards for the use of the device, as can be seen from Figure 2
