Description

[0001] Guide device

[0002] The present invention relates to a guide device with a side rail with horizontal bars and at least two vertical posts, wherein the horizontal bars are each fixed to a post on opposite sides by an end section, and a pull-out guide with at least two rails that can be moved relative to one another, wherein a stationary rail of the pull-out guide is fixed to at least one horizontal bar of the side rail via a fastening device and the fastening device comprises a clamp that is fixed to at least one horizontal bar at or adjacent to a first end section.

[0003] EP 2 532 274 A2 discloses a device for securing a pull-out guide to a side rail using multiple fastening elements. The fastening elements engage around two bars of the side rail, both at the longitudinally extending portion of the horizontal bars and at an angled end section. As a result, each fastening element is precisely adapted to the geometry of the side rail, making it impossible to fix the fastening elements to different side rails with bars of different thicknesses or at different spacings. Furthermore, the fastening elements can only be mounted in the longitudinal direction of the bars, and the pull-out guide is arranged on the inside of the side rail, which reduces the usable interior space in an oven.

[0004] It is therefore an object of the present invention to provide a guide device which enables simple and flexible mounting of a pull-out guide on different side rails and ensures stable fastening.

[0005] This object is achieved with a guide device having the features of claim 1.

[0006] The guide device according to the invention comprises a side rail with horizontal bars and at least two vertical posts, wherein the horizontal bars are each fixed to a post by an end section on opposite sides, at least one end section being angled, and a pull-out guide with at least two rails movable relative to one another, wherein a stationary rail of the pull-out guide is fixed to at least one horizontal bar of the side rail via a fastening device. The fastening device comprises a clamp which is fixed to at least one horizontal bar at or adjacent to a first end section, and on which a plurality of spaced-apart openings are provided for the passage of the end section of the at least one horizontal bar.This allows side rails with horizontal bars of different lengths to be easily used for mounting the pull-out guide, as the end section on the horizontal bar can be inserted through any of the openings. This allows for a high degree of flexibility. Optionally, the fastening device can also have more than one clamp with several openings spaced apart along the length of the horizontal bar for the passage of an end section of the horizontal bar, allowing even greater flexibility in positioning the fastening device.

[0007] Preferably, the width of the openings on the clamp essentially corresponds to the thickness of the wire of the horizontal bar. This allows the clamp to form a stop to prevent the drawer guide from shifting in the extension and retraction directions.

[0008] According to a first variant, the clamp is designed as a strip with at least one recess for inserting a bent end section of a horizontal bar that limits displacement of the clamp. As a result, the clamp can both fix the pull-out guide for support and also secure it against longitudinal displacement. The at least one recess can be formed on a vertical wall section of the clamp, in particular on an upwardly projecting wall section. The recesses are arranged between the wall sections, whereby the provision of multiple recesses allows adaptation to different distances between the posts of a side rail.

[0009] In a preferred embodiment, the clamp has a U-shaped receptacle, viewed in the longitudinal direction, which at least partially encompasses an end section of the horizontal bar of the side rail. The U-shaped receptacle thus forms an anti-tilt device that prevents the pull-out guide from being lowered or raised in the installed position, even if the horizontal bars are formed by a cylindrical wire. To secure the clamp against disassembly, an opening can be cut out in the clamp, into which opening a holding element can be inserted, which is rotatably or displaceably mounted on the clamp. As a result, at least one horizontal bar of the side rail is surrounded on all sides by the fastening device, thus preventing the pull-out guide from being pulled off the side rail.

[0010] The fastening device can be constructed in one or more parts. In a preferred embodiment, the fastening device is made in one piece from a strip-shaped, bent metal sheet. In this case, the fastening device can advantageously be welded to the stationary rail of the drawer guide.

[0011] Preferably, a plurality of clamps are provided, which are fixed to the stationary rail at a distance from one another and between which openings are formed for the passage of the second end section. The length of the openings in the longitudinal direction of the horizontal bars can optionally correspond substantially to the thickness of the bars.

[0012] To fix the clamp in a longitudinally immovable manner, the clamp can preferably comprise a securing element in the form of a tab attached to the stationary rail, in which a recess is provided into which an end portion of one of the horizontal bars engages. The securing element and the clamp can then be used to secure the drawer guide.

[0013] In one embodiment, the guide device has at least two clamps, which are preferably mirror-symmetrical to one another transversely to the pull-out direction of the pull-out guide.

[0014] In a further variant, a clamp of the fastening device engages in a U-shape around at least two horizontal bars of the side rail. An upper leg of the clamp rests on an upper side of the upper horizontal bar and a lower leg rests on an underside of the lower horizontal bar. An inward-facing web can be formed on each of the two legs of the U-shaped section of the clamp, with each web engaging behind one of the two horizontal bars. By means of such a clamp, the pull-out guide is captively fixed to the side rail, with the clamp preferably being bent during assembly so that the inward-facing webs engage behind the respective horizontal bar. In this case, a plurality of clamps can be provided in the longitudinal direction of the stationary rail of the pull-out guide, which are fixed to the stationary rail at a distance from one another.To attach the pull-out guide, it is sufficient for a single clamp to grip two horizontal bars of the side rail, although it is optionally possible for several such clamps to grip two horizontal bars.

[0015] In a further variant according to the invention, the guide device comprises a side rail with horizontal bars and at least two vertical posts, wherein the horizontal bars are each fixed to a post by an end section on opposite sides, and a pull-out guide with at least two rails that can be moved relative to one another, wherein a stationary rail of the pull-out guide is fixed to at least two horizontal bars of the side rail via a fastening device and the fastening device comprises a clamp that engages around two horizontal bars of the side rail in a U-shape, wherein an angled wedge-shaped tongue is provided on the clamp, which rests with opposite edges on each of the horizontal bars. The wedge shape of the tongue allows adaptation to different distances between horizontal bars.For effective manufacturing, the tongue may be formed integrally with the bracket.

[0016] Advantageously, the fastening device has at least two clamps which are mirror-symmetrical to one another transversely to the extension direction of the extension guide.

[0017] The guide device according to the invention is preferably used in a cooking appliance in which at least one food carrier is held movable via the guide device in a cooking chamber.

[0018] The invention will be explained in more detail below using several exemplary embodiments with reference to the accompanying drawings. They show:

[0028] Figures 14 and 15 show two perspective views of the guide device of Figure 11 with a modified side rail, and

[0029] Figures 16A to 16C show several views of a clamp of the guide device of Figure 11.

[0030] A guide device comprises a side rack 1, which can be fixed, for example, in the interior of a cooking appliance. The side rack 1 has a plurality of horizontal bars 2, which in this exemplary embodiment each have an angled end section 5 on opposite sides, which is fixed to a vertical post 3. The end sections 5 can also be designed differently; in particular, only one or no end section can have an angle. The number of posts 3 and horizontal bars 2 can be varied. A pull-out guide 4 is fixed to the side rack 1, which has a plurality of rails that can be moved relative to one another in order to movably support a food carrier.

[0031] In Figures 1 and 2, the pull-out guide 4 is fixed by means of a first fastening device which has a strip-shaped clamp 10 which surrounds a horizontal bar 2 in a U-shape.

[0032] As can be seen from the exploded view of Figure 3, the clamp 10 is designed with almost the same length as the pull-out guide 4 and comprises a U-shaped receptacle 11 which, in the mounted position, is open horizontally towards the posts 3. An upper leg of the U-shaped receptacle 11 has an angled web 12 which is fixed to the stationary rail of the pull-out guide 4. The lower leg 13 of the U-shaped receptacle 11 projects beyond the upper leg and has upwardly directed wall sections 14 at the end, between which recesses 15 are formed. The left section in Figure 3 forms a clamp 10 which is used to fix the fastening device to a first angled end section of a horizontal bar 2, and the right section forms a clamp 10 for fixing the fastening device to a second angled end section of the horizontal bar 2.The two clamps 10 are designed mirror-symmetrically to each other transversely to the extension direction of the pull-out guide 4.

[0033] On the lower leg 13, an upwardly directed spring bar 16 is provided, which serves to lock the clamp 10 to a horizontal bar 2. Furthermore, at least one opening 18 is recessed in the lower leg 13, which is slot-shaped in the illustrated embodiment and into which a bar-shaped retaining element 17 can be inserted. The retaining element 17 is rotatably mounted on the bar 12 at an opening 19 via a bearing element 9. In the exemplary embodiment, two retaining elements 17 are provided, although the number of retaining elements 17 can be varied.

[0034] Figure 4 shows the installation of the pull-out guide 4 on a side rail 1' that is somewhat longer than the side rail 1 in the longitudinal direction of the pull-out guide 4. As a result, when installing the clamps 10, 10', other recesses 15 are used between the wall sections 14, into which an angled end section 5 of a horizontal bar 2 is inserted. The pull-out guide 4 is first positioned on a horizontal bar 2 of the side rail 1' with a pivoting movement.

[0035] After the side rail has been pivoted in, the position shown in Figure 5A is reached, and the angled, upwardly projecting wall section 14 engages behind the horizontal bar 2. The clamps 10, 10' are then pushed onto the side rail 1' until the position shown in Figure 5B is reached. The horizontal bar 2 is now surrounded on three sides in the U-shaped receptacle 11, as is also shown in Figure 5C. In the next step, this position is secured by pivoting the holding elements 17 from the position above the openings 18 until the holding elements 17 at least partially engage in the slot-shaped openings 18, as shown in Figure 5D. In the assembled position, the pull-out guide 4 is held immovably on the side rail 1 or 1'.

[0036] Figures 6 and 7 show a second embodiment of a guide device in which a pull-out guide 4 is fixed to the side rail 1' via a fastening device. The fastening device comprises a clamp 20 which is strip-shaped and has an upper U-shaped receptacle 21 and a lower U-shaped receptacle 22, each of which engages around a horizontal bar 2 of the side rail 1', so that the clamp 20 is fixed to two adjacent horizontal bars 2. The two U-shaped receptacles 21 and 22 are connected to one another via a back 25, so that a clamp 20 captively fixes the pull-out guide 4 to the two bars 2. To secure the pull-out guide against displacement, the clamp 20 comprises an angled tab 27, on which a recess 28 is provided for inserting an angled end section 5 of a horizontal bar 2.

[0037] In Figures 8 and 9, the pull-out guide 4 is fixed to a modified side rail 1, which is shorter in the longitudinal direction of the pull-out guide 4. In this variant, only one clamp 20 is provided, which engages two bars 2 with the two U-shaped sections 21 and 22. The remaining clamps 20 are arranged outside the side rail 1. The fastening device can thus be adapted to different side rails 1 or 1'. Figures 10A and 10B show in detail the clamp 20, which is made in one piece from a metal sheet. The clamps 20 each have an upper U-shaped receptacle 21 and a lower U-shaped receptacle 22, which are open towards one another. One leg of each of the U-shaped receptacles 21 and 22 is connected via the back 25.On the opposite side, the upper holder 21 comprises a downwardly directed web 23 and the lower holder 22 comprises an upwardly directed web 24, which engage around a horizontal bar 2 in the mounted position and can be fixed, for example, by bending.

[0038] At least one clamp 20 is connected via a strip 26 to the bent tab 27, on which the recess 28 is provided for securing the pull-out guide 4 in the longitudinal direction. Multiple tabs 27 and / or multiple recesses 28 can also be provided. The pull-out guide 4 can, for example, be secured laterally in the area of ​​the back 25 or above the upper mount 21 and the strip 26 to the clamp, preferably by a material fit.

[0039] Figures 11 and 12 show a further embodiment of a guide device in which a pull-out guide 4 is fixed to a side rail 1 via a fastening device with two clamps 30. Each clamp 30 engages around two horizontal bars 2 of the side rail 1 and includes a flexible tongue 34 that engages between the two bars 2. The clamps 30 are arranged such that an edge can be placed against an angled end section 5 in order to secure the fastening device against displacement of the pull-out guide 4 in the longitudinal direction. In this embodiment, the clamps 30 are mirror-symmetrical to one another transversely to the extension direction of the pull-out guide 4.

[0040] In Figures 14 and 15, the pull-out guide 4 is fixed to a modified side rail 1', and the clamps 30 hold the pull-out guide to two horizontal bars 2 of the side rail 1'.

[0041] In Figures 16A to 16C, one of the clamps 30 is shown in detail. Each clamp 30 comprises a U-shaped section 31, which can be placed from above onto a horizontal bar 2 of a side rail 1 or 1'. The U-shaped section 31 comprises a first downwardly directed leg

[0042] 32 and a second downward-directed leg 33. On the leg

[0043] 33, the flexible tongue 34 is integrally formed, which is connected to the leg 33 via a bend 36 and protrudes at an angle from this to the other leg 32. A recess 35 is formed in the leg 32, and one end 37 of the flexible tongue 34 protrudes into the recess 35. The flexible tongue 34 is wedge-shaped in plan view and rests with its opposite edges against a respective horizontal bar 2 of a side rail 1 or T. The wedge shape of the flexible tongue 34 allows tolerances in the thickness or spacing of the horizontal bars 2 to be compensated for. The above embodiments can be combined with one another as desired. For example, a clamp 30 can be used in addition to the fastening device of Figures 6 and 7. Furthermore, the number of clamps for fastening the pull-out guide 4 can be varied.
