DETAILED DESCRIPTION OF THE DRAWINGS

[0018] FIG. 1 shows an oven 1 as an example of a cooking appliance in a perspective schematic illustration. A door 2 is opened to allow a view into an interior 3 of the oven 1.

[0019] A grid-type side part 5, also referred to as a side grid 5 hereafter, is situated in the interior 3 of the oven 1 on each of the opposing sides. The side grid 5 extends from a front side 4 of the oven in the direction of a rear side and has vertically extending pillars 6 and at least one, in the present case a plurality of horizontally extending rods 7. The horizontal rods 7 have an end section 8 bent over substantially perpendicularly on both sides. The rods 7 are each fixed using this angled end section 8 on at least one of the pillars 6, in particular welded thereto.

[0020] In the illustrated exemplary embodiment, each two of the horizontal rods 7 are situated in parallel at a slight distance from one another, so that a food support can be pushed with its side edge between each two adjacent rods 7. It is apparent that the number of the horizontal rods 7 and/or the pillars 6 can deviate from the example shown here in embodiments of the side grid 5. Furthermore, it is to be noted that a comparable side grid, on which at least one pullout guide is fastened according to the application, can also be used in other domestic appliances and/or items of furniture.

[0021] One pullout guide 10 is fastened here on one of the rods 7 by way of example, which has a guide rail 14 and a slide rail 11, which is extendable forward in relation to the guide rail 14. The slide rail 11 is delimited in the front region by a cover plate 12. A stop pin 13 is arranged in the rear region of the slide rail 11. A food support can be laid between cover plate 12 and stop pin 13 on the slide rail 11, which can be extended conveniently by means of the pullout guide 10.

[0022] The pullout guide 10 is fixed with the aid of two quick-action fastening elements 20 on the corresponding horizontal rod 7 of the side grid 5. The quick-action fastening elements 20 are described in greater detail in conjunction with FIGS. 2a, 2b and 3a, 3b, which are described hereafter. A method according to the application for fixing the pullout guides 10 on the rod 7 by means of the quick-action fastening elements 20 will also be explained on the basis of these figures.

[0023] FIG. 2a shows a section of the side grid 5 and the pullout guide 10 in a perspective illustration. FIG. 2a is a diagonal view of the rear of the side grid 5, i.e., the side which presses against the wall of the interior 1 shown in FIG. 1. FIG. 2b shows a sectional illustration through the side grid 5 and the pullout guide 10, wherein the section is executed perpendicularly to the horizontally extending longitudinal section of the horizontal rod 7 with the direction of view along the longitudinal extension of the rod 7.

[0024] In the installation stage shown in FIGS. 2a and 2b, the pullout guide 10 is pushed onto the rod 7 with the aid of two quick-action fastening elements 20, a front and a rear quick-action fastening element 20. The pullout guide 10 and the quick-action fastening elements 20 are connected to one another in this case via a supporting section 15 of the guide rail 14 of the pullout guide 10, in particular in a spot welding method. The quick-action fastening elements 20 each have a clamp-type holding section 21, which at least partially encompasses the rod 7 in its longitudinal extension section. In the present exemplary embodiment, the clamp-type holding section 21 has the shape of a recumbent U-shaped profile having an upper leg 22, which is connected to the support section 15, and a lower leg 23. A catch element 24 is arranged on the lower leg 23, which is extended upward in a springy manner in the direction of the upper leg 22. If the fastening element is pushed horizontally onto the rod 7, the catch element 24 initially yields downward, to then spring upward after it is completely pushed on and thus to engage behind the rod 7.

[0025] A further clamp-type holding section 25 is formed on the quick-action fastening element 20. This further holding section 25 also has a U-shaped profile, which is pivoted in its alignment by 90° in relation to the U-shaped profile of the clamp-type holding section 21, however. The U-shaped profile of the further holding section 25 also at least partially encompasses the bent-over end section 8 of the rod 7 and thus prevents a displacement of the quick-action fastening element in the direction of the longitudinal extension of the rod 7.

[0026] It can be provided that both the front and also the rear of the fastening elements 20 have the further clamp-type holding section 25. However, it is also conceivable that only one of the two fastening elements 20, either the front or the rear, has both the clamp-type holding section 21 and also the further clamp-type holding section 25. By pushing on the fastening elements 20 and latching with the aid of the catch element 24, the pullout guide 10 is already fixed on the rod 7 in the installation state shown in FIGS. 2a and 2b so that unintentional falling off is prevented. If both fastening elements have the further clamp-type holding section 25, the pullout guide 10 is also fixed in both directions (to the front and to the rear) in the longitudinal extension direction.

[0027] Because of material tolerances in the diameter of the rod 7 and because of manufacturing tolerances during the formation of the U-shaped clamp-type holding sections 21 and 25 and also tolerances which relate to the distance of the two fastening elements 20 in the longitudinal extension direction of the rods 7, the installation state of the pullout guide 10 on the rod 7 shown in FIGS. 2a and 2b is not without play, however, which can result in rattling during operation of the pullout guide 10.

[0028] FIGS. 3a and 3b show, in the same way as FIGS. 2a and 2b, the side grid 5 with finally-installed pullout guide 10 after application of an installation method according to the application.

[0029] In the installation method according to the disclosure, proceeding from the installation stage shown in FIGS. 2a and 2b, the clamp-type holding sections 21, and optionally the further clamp-type holding sections 25, are plastically deformed so that a form fit exists between the clamp-type holding sections 21, 25 and the corresponding sections of the rods 7. Due to the plastic deformation, the clamp-type holding sections 21, 25 are fastened without play on the rod 7, whereby tolerances in the diameter of the rods 7, the spacing of the bent-over end sections 8, and the spacing of the fastening elements 20, as well as the dimensions of the U-shaped profile of the clamp-type holding sections 21, 25 are compensated for. Rattling or similar operation noises which previously resulted from the fastening, which involved play, are prevented.

[0030] The plastic deformation can preferably be performed by means of a suitable embossing tool, for example, pliers. The use of special pliers is particularly advantageous, the jaws of which are adapted with regard to the alignment and dimensions thereof to the shape of the fastening element 20 and the available dimensions between fastening element 20 and guide rail 14. After plugging and latching the fastening elements 20 onto the corresponding rod 7, crimping (embossing) can be performed in a simple manner even in the case of a side grid 5 which is already situated in the interior 1 of the appliance (cf. FIG. 1).

[0031] As can be seen well in FIG. 3b, the catch element 24, which is formed as a spring tongue, presses with its free end against the upper leg 22 after completed crimping in the exemplary embodiment. The catch element 24 is at least above half of the diameter of the rod 7 after the crimping. In this manner, a structure is provided, which cannot be pulled off of the rod 7 even in the event of a large force acting on the pullout guide.

[0032] In the illustrated exemplary embodiment, the pullout guide 10 is initially clipped in a latching manner on the corresponding rod using its fastening elements 20 (cf. installation state of FIGS. 2a, 2b). In an alternative embodiment of the fastening element 20, it does not have a catch element 24, so that temporary latching does not occur after the fastening elements 20 are plugged onto the rod 7. A temporary clamping fastening of the fastening elements 20 on the rod 7 can nonetheless be performed by the geometry and dimensioning of the clamp-type holding sections 21 and optionally the further clamp-type holding section 25. The final fixing is then performed, comparably to FIGS. 3a and 3b, by the plastic deformation of parts of the clamp-type holding sections 21, 25, in particular a free lower leg (cf. leg 23 in FIGS. 3a, 3b).
