The socket also includes a plurality of locating recesses extending radially from the central region of the body to overlie the other side of the wall to prevent the socket from being removed from the hole. The preamble of claim 1 is known from this document.

The object of the invention is in particular to provide a generic Trägerervor direction with the possibility of a simple tolerance compensation, which is easy to assemble and disassemble. The object is achieved by the characterizing features of claim 1, while advantageous embodiments and modifications of the invention can be taken from the dependent claims and claims.

The invention relates to a carrier device, in particular for a cooking appliance, with at least one carrier means and with at least one first receiving means fastened to a wall for a first carrier part of the carrier means.

It is proposed that the receiving means has at least a first receiving area for insertion of the first carrier part in an insertion direction and a second receiving area into which the first carrier part is movable after insertion.

By dividing into a first and in a second receiving area tolerances can be compensated advantageous and jamming during assembly and disassembly can be avoided. In principle, it is conceivable that the first carrier part is designed pivotable in the second receiving area, but tolerances can advantageously be easily compensated for by a variable displacement in a particular translational displacement. Furthermore, a cleaning-friendly carrier device can be achieved.

By the receiving means is designed as a fastened to the wall component and not formed by the wall itself, this can be particularly advantageous designed for its function, an undesirable, negative influence on the wall can be at least largely avoided and easy mounting and dismounting over a long life be achieved with a present after assembly safe connection. The receiving means may be formed of various materials that appear appropriate to those skilled in the art, such as a metal, a heat-resistant plastic, etc. Furthermore, the carrier device of suspension grids, telescope systems, etc. may be formed.

If the insertion direction is perpendicular to a direction of movement of the first carrier part into the second receiving region, an easy-to-understand assembly and disassembly and also a particularly secure connection between the carrier and the receiving means can be achieved.

The receiving areas may have different forms that appear appropriate to the person skilled in the art. However, particularly simple design and inexpensive receiving means and support means can be achieved when the first and the second receiving area form a keyhole-shaped recess with a wide and a narrow area. Furthermore, a largely self-explanatory assembly and disassembly can be achieved.

In a further embodiment of the invention, it is proposed that the first carrier part in the second receiving area is positively fixable against the insertion direction. Compared with a possible purely non-positive locking in the second receiving area advantageously small assembly and D emontagekräfte achieved and yet an unwanted release of the first carrier part from the receiving means can be safely avoided.

A positive fixation against the insertion direction can be easily achieved by the first carrier part has a matched to the second receiving area. Forming the first and the second receiving area a keyhole-shaped recess with a wide and a narrow area, the first support member can be inexpensively adapted by squeezing to the second receiving area, whereby existing systems can be easily and inexpensively redesigned.

It is also proposed that the first receiving means can be fixed in the wall by means of a spring element, whereby the spring element can advantageously be stored in the wall at least largely free of play as a result of a frictional connection without having to comply with tight, cost-intensive tolerances.

If, moreover, the first carrier part can be fixed in the first receiving means via the spring element, furthermore the first carrier part can advantageously be fixed in the receiving means at least largely free of play and additional components, in particular spring elements, installation effort and costs can be saved.

If at least a second, mountable in the wall receiving means is provided, which has a first receiving area for insertion of a second carrier part in an insertion direction and a second receiving area, in which the second carrier part is movable after insertion, can by a special movement of the carrier with particular small assembly and disassembly forces an advantageous secure connection can be achieved.

If the first and the second receiving means are of identical design, the number of different components can be reduced and the costs can be reduced. If the first receiving means is arranged rotated in the assembled state compared to the second receiving means, securing means of the carrier means in different directions, parallel to the wall, can advantageously be achieved by the receiving means. Preferably, in a front region, the support means can be secured in the horizontal direction and in a rear region in the vertical direction, so that in particular By the rear receiving means an undesired tilting of the carrier means during loading thereof can be avoided.

Fig. 1 shows a section of a baking oven 2a with a cooking chamber defining muffle. In lateral Muffelwandungen 10a are approximately halfway up the muffle each in a front area first recesses and a rear area, on itself Height, second recesses introduced. In the recesses identical, trained as sockets receiving means 4a, 4a 'of a support device 1a are mounted, wherein each of the front receiving means 4a relative to the rear receiving means 4a' is rotated by 90 °.

The support device 1a comprises two identical support means 3a, wherein only one of the two is shown and described below. The support means 3a can be fastened with integrally formed support parts 11a, 11a 'via the receiving means 4a, 4a' and the sleeve wall 10a ( Fig. 2 ). The support means 3a, when mounted in a mounting position on a muffle wall 10a, comprises a front and a rear, vertically extending connecting rod 17a, 17a ', via which ten horizontally extending guide rods 18a-27a are connected to form a unit. The guide rods 18a-27a each include at their front and at the rear end in each case in the mounted state perpendicular to the muffle wall 10a extending portion between which a parallel to the muffle wall 10a, extending from the front portion in the rear portion is arranged.

The partial regions of the guide rods 18a-22a and 24a-27a extending perpendicularly to the muffle wall 10a terminate substantially in one plane with a side of the connecting rods 17a, 17a facing the muffle wall 10a. To the guide rod 23a are in the direction perpendicular to the muffle wall 10a on the connecting rods 17a, 17a 'out beyond extending support members 11a, 11a' integrally formed, which are inserted in the assembled state in the receiving means 4a, 4a '.

The receiving means 4a, which, as already stated, is of identical design to the receiving means 4a 'and is described below by way of example for both receiving means 4a, 4a', has a first region pointing into the cooking chamber when mounted and a second region extending through the muffle wall 10a On area with which the receiving means 4 a is inserted through the recess of the muffle wall 10 a during assembly on the muffle wall 10 a in the assembly direction 28, which coincides with an insertion direction 13 of the carrier part 11 a into the receiving means 4 a ( Fig. 3 to 8 ). The first region, which has a cross-sectional area with a round outer contour, has a stepped outer contour in the longitudinal direction with a diameter decreasing in the mounting direction 28. The first area thus forms a groove-shaped receiving area 29a, in which advantageous components, such as in particular a catalytic converter, can be hung. The first area is in the assembled state with an end face 38a facing away from the cooking chamber on an inner side of the muffle wall 10a.

The second area of the receiving means 4a has a cross-sectional area which has a substantially rectangular outer contour in a first partial area 30a, followed by a second partial area 31a which has a contour which tapers in the direction of a rounded end of the cross-sectional area. The recesses in the muffle wall 10a are correspondingly adapted to the contours of the cross-sectional areas of the second regions of the receiving means 4a, 4a 'that are asymmetrical to a central axis 55a, so that incorrect assembly of the receiving means 4a, 4a' is reliably avoided.

In the second area, grooves 32a, 33a extending in parallel to the muffle wall 10a are provided on opposite sides, in the mounted state. If the receiving means 4a, 4a 'are inserted into the recesses of the muffle wall 10a, they can be secured in a non-positive and non-positive manner in the recesses via a respective clip-like spring element 16a, 16a'. The spring elements 16a, 16a 'are inserted on the side facing away from the cooking chamber of the muffle wall 10a substantially parallel to the muffle wall 10a in the grooves 32a, 33a, 32a', 33a '. In the inserted into the grooves 32a, 33a, 32a ', 33a' state, the spring elements 16a, 16a 'are based on opposite struts 34a, 35a, 34a', 35a 'on the muffle wall 10a and act with contact areas 36a, 36a' in the grooves 32a, 33a, 32a ', 33a' on the receiving means 4a, 4a 'and pull them into the recesses of the muffle wall 10a.

Further, the receiving means 4a has a first receiving portion 12a for insertion of the support member 11a in the insertion direction 13 and a second receiving portion 14a, in which the support member 11a is translationally displaceable after insertion, wherein the insertion direction 13 perpendicular to a direction of movement 15a of the support member 11a in the second receiving area 14a is.

The first and the second receiving area 12a, 14a form a keyhole-shaped recess, wherein the first receiving area 12a has a wide and the second receiving area 14a forms a narrow area of the keyhole-shaped recess ( Fig. 4 ). The support parts 11a, 11a 'are respectively in the second receiving portion 14a, 14a' and in the insertion direction 13 positively fixed, which in particular on the support means 1a laterally, horizontally acting forces advantageous on the support members 11a, 11a 'and on the receiving means 4a, 4a' can be supported on the muffle wall 10a. For this purpose, the carrier parts 11a, 11a 'each have a region 37a adapted to a pinching on the second receiving region 14a, 14a', just before their free end ( Fig. 9 ). A remaining thickness 39a of the support part 11a in the region 37a essentially corresponds to a width 40a of the second receiving region 14a. The support parts 11a, 11a 'are of identical construction, so that the support means 3a can be mounted both on a left side of the cooking chamber and on a right side of the cooking chamber. In the second receiving area 14a, 14a 'in the recesses radially inwardly facing projections 41a, 42a are formed, which have in the direction of the first receiving portion 12a, 12a' integrally formed insertion bevels to each advantageous guidance of the support member 11 a, 11 a 'from the first Reception area 12a, 12a 'in the second receiving area 14a, 14a' without tilting to allow.

In order to achieve that the support parts 11a, 11a 'when mounted in the receiving means 4a, 4a' or when moving from the first receiving portion 1 2a, 1 2a 'in the second receiving portion 14a, 14a' in an at least largely play-free storage position in the Receiving means 4a, 4a 'are drawn, the receiving means 4a, 4a' on a side facing away from the cooking chamber each have a sloping end face 43a, 43a ', starting from the first receiving area 12a, 12a' towards the second receiving area 14a, 14a ' have a positive slope. When the carrier parts 11a, 11a 'are displaced from the first receiving region 12a, 12a' into the second receiving region 14a, 14a ', the carrier parts 11a, 11a' are each provided with their rim facing the cooking region of the region 37a, 37a 'formed by the pinch. pulled against the projections 41a, 42a ( Fig. 8 ).

When mounting the support means 3a on the muffle wall 10a, the rear support part 11a 'is first inserted into the first receiving area 12a' of the rear receiving means 4a ', which is arranged in the cooking space in front of the second receiving area 14a', the first and the second receiving area 12a ', 14a' are arranged horizontally one behind the other ( Fig. 1 . 6 and 7 ). Subsequently, the support part 11a 'from the first receiving area 12a 'moved further back into the cooking chamber in the direction of movement 15a' in the second receiving area 14a '. In particular, by a variable displacement in the direction of movement 15a 'tolerances of the support means 3a and tolerances with respect to the position of the recesses in the muffle wall 10a can be compensated.

If the carrier part 11a 'is guided into the second receiving area 14a', the front carrier part 11a is inserted into the first receiving area 12a of the front receiving means 4a, which is arranged in the cooking space above the second receiving area 14a, the first and the second receiving area 12a, 14a are arranged vertically above one another. Subsequently, the support part 11a is displaced from the first receiving area 12a downwards in the direction of movement 15a into the second receiving area 14a.

In order to avoid that the front support part 11a is undesirably dug out of the second receiving area 14a, a spring arm 44a is integrally formed on the spring element 16a ( Fig. 7 ), which is deflected during insertion of the support member 11a in the first receiving portion 12a upwards and loaded in the second receiving portion 14a, the support member 11a in the direction away from the first receiving portion 12a direction, down.

The support means 3a has in the lower region, above the lower two guide rods 26a, 27a in its connecting rods 17a, 17a 'formations 45a, 45a', which point in the assembled state of the support means 3a in the muffle wall 10a and rounded, the muffle wall 10a gentle bearing surfaces form. The formations 45a, 45a 'have substantially the same height as the second, over the Muffelwandung 10a projecting portion of the receiving means 4a, 4a', so that an advantageous substantially vertical orientation of the connecting rods 17a, 17a 'is achieved. In the upper region, the support means 3a is supported on the muffle wall 10a via end faces of the subregions of the guide rod 19a extending perpendicularly to the muffle wall 10a, which distance is substantially equal to the height of the second regions of the receiving means 4a, 4a 'between the connecting rods 17a, 17a' and bridge the muffle wall 10a. Instead of the guide rod 19a, the support means 3a could be supported on the muffle wall 10a in the upper area above the lower formations 45a, 45a 'corresponding formations. Because of the upper Range compared to the lower area usually lower contact forces, however, can basically be dispensed with formations in the upper area. The guide rods 18a-27a can be used directly as bearing surfaces for baking trays or the like or can be used for fastening telescopic rails 46a, as shown in FIG Fig. 2 is indicated, or may be replaced by telescopic rails 46a.

The disassembly process of the support means 3a is correspondingly reversed as the assembly process, both the assembly and disassembly can be done with one hand.

In the 10 to 14 further alternative embodiments are shown. In the alternative embodiments, parts that are essentially identical in the description are basically numbered with the same reference numerals, with the letters "a", "b" and "c" being used to distinguish the exemplary embodiments. Furthermore, with regard to features and functions that are the same, the description of the exemplary embodiment in FIGS Fig. 1 to 9 to get expelled. The following description is essentially limited to the differences from the exemplary embodiment in FIGS Fig. 1 to 9 ,

Fig. 10 shows a section of an alternative oven 2b with a cooking space limiting muffle and an alternative carrier device 1b with two different receiving means 4b ', 47b. The rear receiving means 4b 'for receiving a carrier part 11b' of a support means 3b is substantially identical in design to the receiving means 4a, 4a 'and has the same mounting position as the receiving means 4a'. The receiving means 4b 'is held with a clip-shaped spring element 16b' in its mounting position, which is inserted into grooves 32b ', 33b' of the receiving means 4b '( Fig. 12 ). In order to avoid that the spring element 1 6b 'undesirably disengages from the grooves 32b', 33b ', latching lugs 48b', 49b 'are integrally formed on the spring element 16b', which latch in on insertion of the spring element 16b 'and edges engage behind the grooves 32b ', 33b'.

In contrast to the receiving means 4b ', the front receiving means 47b comprises only one receiving region into which a carrier part 11b of the carrier 3b can be inserted ( Fig. 10 and 11 ). Otherwise, the receiving means 47b substantially corresponds to the receiving means 4b. The receiving means 47b is held with a clip-shaped spring element 16b in its mounting position, which is inserted into not shown grooves of the receiving means 47b. The spring element 16b is supported on a side of a muffle wall 10b facing away from the cooking space and acts via edges of the grooves on the receiving means 47b in the direction away from the cooking space. In order to avoid that the spring element 16b undesirably disengages from the grooves, locking lugs 48b are integrally formed on the spring element 16b, which snap into engagement with the insertion of the spring element 16b and engage behind edges of the grooves.

When viewed in the mounted state, a vertically oriented, S-shaped spring arm 44b is formed on the spring element 16b. If the support means 3b is inserted with its carrier part 11b in the insertion direction 13 into the receiving means 47b, the S-shaped spring arm 44b engages with its lower arc element in a substantially longitudinally cut semicircular recess 50b of the support member 11b. The lower arch element of the S-shaped spring arm 44b forms an insertion bevel 51b and an embodiment bevel 52b. The insertion bevel 51b acts upon engagement of the support member 11b in the receiving means 47b with a phase 54b of the support member 11b and the execution slope 52b acts on disengagement of the support member 11b from the receiving means 47b with a toward the free end of the support member 11b the recess 50b subsequent, flat inclined surface 53b together to allow for a secure hold of the support member 11 b in the receiving means 47b also a simple engagement and disengagement. For disengagement can be easily pulled on the support means 3b in the region of the support member 11 b opposite to the insertion direction 13.

The assembly of the support means 3b corresponds to the fact that the front support part 11b of the support means 3b must be inserted only vertically into the receiving means 47b, the mounting of the support means 3a of the support device 1a. The carrier device 1 b according to the Fig. 10 to 13 is particularly advantageous in cooking appliances with telescopic telescopic rails, b ei which by the front receiving means 47 b e in unwanted lifting of the support means 3b from its mounting position, and in particular when closing a oven door with telescopic rails extended, can be safely avoided.

The support parts 11b, 11b 'are of identical construction, so that the support means 3b can be mounted both on a left side of the cooking chamber and on a right side of the cooking chamber ( Fig. 13 ). In each case proceeding from the free end of the carrier parts 11b, 11b 'in the longitudinal direction thereof, the inclined surface 53b, 53b', the recess 50b, 50b 'and a region 37b, 37b' formed by a pinch are arranged one behind the other.

In Fig. 14 there is shown an alternative support means 3c with differing support parts 11c, 11c 'which, like the support means 3b, can be mounted in receiving means 47b and 4b. The front support part 11c has an inclined surface 53c and a recess 50c and no area formed by a pinch, and the rear support part 11c 'has a crimped portion 37c and no inclined surface and no recess for a spring arm. The support members 11 c, 11 c 'allow for properly mounted receiving means 4b, 47b only a mounting of the support means 3c on a left side in a cooking chamber, which on the support members 11 c, 11 c' incorrect assembly can be safely avoided when the carrier 3c is intended only for mounting on the left side, for example, when by means of the guide rods 1 8c, 1 9c, 2 2c, 2 3c in the insertion direction of a baking sheet inclined support levels to be achieved. reference numeral 1 support device 34 strut 2 Cooking appliance 35 strut 3 carrier 36 plant area 4 receiving means 37 Area 10 wall 38 front 11 support part 39 Strength 12 reception area 40 width 13 insertion 41 head Start 14 reception area 42 head Start 15 movement direction 43 front 16 spring element 44 spring arm 17 connecting rod 45 formation 18 guide rod 46 telescopic rail 19 guide rod 47 receiving means 20 guide rod 48 locking lug 21 guide rod 49 locking lug 22 guide rod 50 recess 23 guide rod 51 insertion bevel 24 guide rod 52 execution slope 25 guide rod 53 sloping surface 26 guide rod 54 phase 27 guide rod 55 central axis 28 mounting direction 29 reception area 30 subregion 31 subregion 32 groove 33 groove
