DETAILED DESCRIPTION OF THE INVENTION

[0043] FIG. 1 illustrates a microwave oven 1 having guide devices 2, 3 according to the present invention located opposite one another in a drawn-out state. A food tray 6 is arranged in a displaceable manner on the pull-out rails 4, 5. The pull-out rails are displaceable on fixed rails 7, 8. The fixed rails 7, 8 are provided, for example, on side walls 9, 10 or on a shelf support on the side wall of an interior space 11 of the microwave oven 1, for example, in a secured state or such that they can be adjusted in height.

[0044] The construction of a guide device in terms of the arrangement of rails 12, 13 is illustrated in a front view in FIG. 2. For example, the rail 12 is a fixed rail and the rail 13 is a pull-out rail. The rail 13 has, for example, an anchoring element 14 for a food tray.

[0045] If the rail 12 is a fixed rail, its main portion 15 is mounted, for example, on the side wall of a microwave oven. Side portions 16, 17 project from one side of the main portion 15 in the direction of the other rail 13, which in that case is a pull-out rail. The rail 13 likewise has a main portion 18, on which side portions 19, 20 project from one side in the direction of the rail 12. The rails 12, 13 here are nested one inside the other such that the lowermost side portion 16 of the rail 12 overlaps the side portion 20 of the rail 13 on the underside, wherein the uppermost side portion 19 of the latter overlaps the side portion 17 of the rail 12 at the top.

[0046] This creates a space which accommodates guide rollers and which at the same time, as result of the type of nested arrangement, prevents, in particular, microwaves which radiate in from the outside from penetrating into the nested arrangement.

[0047] Therefore, as result of this arrangement, for example, guide rollers are shielded from microwaves in a nested space 21, so that no unwanted parasitic effects are caused there.

[0048] FIG. 3 and FIG. 4 show a rail 22 with guide rollers 23, 24 arranged thereon. The guide rollers are mounted in a rotatable manner, for example, on roller axles 25, 26. The roller axles 25, 26 are mounted securely in a main portion 27, for example, as indicated in the sectional image in FIG. 4, by being pressed in. The guide rollers 23, 24 advantageously roll easily and noiselessly on the roller axles 25, 26, for example, with the aid of a lubricating medium.

[0049] As can be seen in FIGS. 3 and 4, the rail 22 has a notch 28. As a result, in particular, one guide roller, for example, the guide roller 24, protrudes over an outer edge 29 of a side portion 30 of the rail 22, the side portion adjoining the main portion 27.

[0050] It is thus possible for the guide roller 24 to reach a side portion 31, which overlaps the side portion 30 and belongs to a different rail 32, for example, a pull-out rail, and roll on an inner side of this side portion 31 (see FIG. 6).

[0051] The axle 26 for the roller 23, in contrast, is arranged at a lower level, as seen over a height of the rail 22, than the axle 25 for the guide roller 24, and so, rather than rolling on the side portion 31 like the guide roller 24, the guide roller 23 rolls on the opposite side portion 33 of the rail 32.

[0052] The roller axles 25, 26 are preferably offset on the main portion 27 perpendicularly in relation to a longitudinal extent of the rail 22, and so the guide rollers 23, 24 preferably roll internally on the respective side portions 30, 33 in a closely confined manner within an inside width of the rail 32, and this results in well-defined guidance of the rail 32 in relation to the rail 22.

[0053] FIG. 6 shows, for example, a perspective front view, and FIG. 5 shows a rear view of the rail arrangement from FIG. 6.

[0054] It can be seen in FIG. 5 that the rail 22, which according to FIG. 6 provides guidance for the rail 32 in the front region via the guide rollers 23, 24, is itself guided via guide rollers 34, 35, which are arranged on a main portion 36 via roller axles 37, 38.

[0055] The guide roller 34 here rolls on an inner side 39 of the side portion 30 of the rail 22, wherein the guide roller 35, of which only that section which is not overlapped by the guide roller 34 is visible in FIG. 5, rolls on an inner side 40 of a side portion 41 of the rail 22 via the roller axles 38, of which likewise only that section which is not overlapped by the roller axles 37 is visible. The roller axle 38 is mounted on the main portion 36 of the rail 32, for example, the roller axles 38 are mounted securely therein, for example, by being pressed into the main portion 36.

[0056] The guidance of the rail 22 in relation to the rail 32 is thereby defined in the opposite end region of the rail arrangement, as seen in FIG. 6.

[0057] So that the guide roller 35 can reach the side portion 41 of the rail 22, the rail 32 is provided with a notch 42, corresponding to the notch 28, in a mounting region of the guide rollers 34, 35, as is the case in the opposite end region of the rail 22.

[0058] FIGS. 7 and 8 show a guide device 45 in a drawn-out, to be precise fully drawn-out, state in FIG. 7 and in a pushed-together, to be precise fully pushed-together, state in FIG. 8.

[0059] As explained above, the rail 32 can be considered, for example, to be the pull-out rail, with an anchoring element 14 and a further anchoring element or stop element 44 for a food tray, whereas the rail 22 constitutes the fixed rail, which is configured, for example, for secure mounting on a side wall of an interior space of a microwave oven or, by way of fastening mechanisms, on a shelf support on a side wall.

[0060] The rails according to FIGS. 7 and 8 are illustrated in a transparent state in order for the guide rollers 23, 24 and 34, 35 to be visible.

[0061] In FIG. 7, the guide rollers have been completely pushed together, the pull-out rail having been pulled out to the maximum extent. In contrast, according to FIG. 8, the rails 32, 22 have been pushed one inside the other, and therefore represent the state in which a food tray has been pushed, for example, into a microwave oven.
