Description

The present invention relates to fasteners for releasably securing a guide rail to a side rail secured to a side wall of a space enclosed by a plurality of walls, the side rail having at least two spaced-apart vertical rods and at least one horizontal rod connecting the vertical rods Rod having a central longitudinal extension portion located inboard of the vertical rods and having at both ends angled end portions secured with their respective free ends to respective ones of the vertical rods and substantially perpendicular to the vertical rods, and the fastener a holding portion, which at least partially surrounds a portion of a horizontal bar of the side rail in the assembled state, and guide rails with such fasteners.

In household appliances, such as ovens, dishwashers, microwave ovens, etc. are often side rails, which are provided for guiding and edition of food supports. Usual side rails comprise at least two vertically extending rods and these connecting horizontal rods which are connected via angled end portions with the vertical rods and between which a food support are guided and on which it can rest. The horizontal bars are usually arranged in pairs one above the other. Further bars located on such side rails serve to secure e.g. in a furnace muffle.

It has been shown that the sliding behavior on the horizontal bars of a side rail is comparatively poor and complete removal of the food support without additional manual support is not possible.

For this reason, telescopic guides are increasingly used in such household appliances. In order to enable the attachment of such telescopic rails at different heights within the muffle, it has proved to be advantageous to make the telescopic rails so that they are releasably secured to a side rail. In the WO 2007/090738 For example, such a system is described in which quick-fastening elements partially surround a horizontal bar of a side grid in its longitudinal extension region and in its angled end section in a clip-like manner.

However, it has been found that in such systems tilting of the telescopic rail in the direction of the muffle side wall, in particular when removing a food support can not be reliably prevented. Moreover, in known systems, the telescopic extensions are often mounted on side rails so that their support surface for food support runs at a distance to the side rails. This means that the food carriers, which can be used with the telescopic extensions, must be narrower than the food carriers, which are pushed directly onto the side rails.

Accordingly, it has been the object of the prior art to provide fasteners which allow easy and secure mounting and detachment of guide rails on a side rail while preventing tilting of the guide rail about the axis of a horizontal bar, with the space within the household appliance, z. B. the muffle of a furnace is optimally utilized.

According to the invention this object is achieved by a fastener of the type mentioned, having a support portion which adjoins the holding portion and / or forms a part thereof and which rests on the horizontal rod, and provided for fixing the guide rail to the Supporting portion subsequent and perpendicular to this fastening tab, wherein the fastening tab is arranged in or parallel to the plane defined by the vertical rods plane wall side of the longitudinal extension region of the horizontal rod.

By the combination of a holding portion, a support portion and a fastening tab, which runs in or parallel to the plane defined by the vertical bars wall side of the longitudinal extension region of the horizontal bar, tilting about the bars of the side rail is prevented. In addition, this arrangement allows the attachment of a guide rail so that the guide rail projects little or not beyond the dimensions of the side rail out into the interior of the household appliance. As a result, the interior is optimally utilized even with a combination of a side rail and attached guide rails of telescopic extensions and the food supports, which are intended for support on the side rails, are also suitable for use with telescopic extensions so attached.

For fastening a guide rail, two fastening elements are preferably used, of which preferably one is located in each case at one end of the guide rail. This means that the fasteners are mounted adjacent to or directly adjacent to the horizontal bars of the side rail. It will be between a back and a distinguished front fastening element. Unless otherwise indicated, the embodiments refer to either a front or rear fastener or both. The fastening elements may preferably be different, or according to preferred embodiments mirror-symmetrical to each other.

The terms "interior side" and "wall side" are used herein with reference to the side rail, portions of the fasteners and the guide rail. Here, "interior side" refers to a side or surface facing the interior (e.g., cooking) of the home appliance. "Wall-side" refers to a side or surface which faces towards the inner wall of the household appliance, e.g. the muffle wall, points. The term "front" generally refers to an area near the opening of the household appliance, whereas "rear" refers to the area on the rear wall of the household appliance.

By encompassing is meant that the holding portion covers an angular range of more than 90 ° of the horizontal bar, wherein the holding portion does not have to be parallel to the surface of the horizontal bar. In certain embodiments, the holding portion is comprised of two or more tabs that abut substantially opposite surfaces of the horizontal bar. The tabs may be offset from one another along the axis of the respective region of the horizontal bar.

The term "plane spanned by the vertical bars" refers to an imaginary plane passing between the vertical bars.

At the mounting tab, which can also perform other functions of the fastener, a guide rail can be attached to the fastener by welding, gluing, riveting, screw or other suitable attachment means. The guide rail is connected with its wall-side vertical surface with the also in the assembled state vertically extending mounting strap. Preferably, the fastening element is designed so that it is suitable for the attachment of a guide rail of a full telescopic extension and / or partial extract. In certain embodiments, the attachment tab is cranked. By the offset, a further adaptation of the fastening element to the lateral extent of the telescopic rail, to which the guide rail belongs, take place. For example, partial extension rails are narrower than full extension rails, so that when using partial pull-out rails usually a cranking of the fastening tab is required. Partial extension rails can also have a lower profile height than full extension rails, and this can also be compensated by a bend of the fastening tab.

The support portion is designed in preferred embodiments so that it serves with its not resting on the rod side as a support for the guide rail. In certain embodiments, the support portion is on the longitudinal extent of the horizontal bar on.

According to a preferred embodiment of the invention, the fastening tab is in the assembled state of the fastener above the support portion. The guide rail and thus also the associated telescopic extension thereby extends above the rod. In such an embodiment, tilting of the guide rail and thus of the telescopic extension can be particularly well prevented relative to the side rails, since the guide rail is located above the horizontal bar of the side rail and rests in certain embodiments directly or indirectly on the support portion of the fastener on the horizontal bar ,

Particularly preferably, the support section (3) is in the mounted state of the fastener at least on the angled end portion (13) of the horizontal bar.

According to certain embodiment of the invention, the support section lies on the longitudinal extension region and on an angled end section of the horizontal rod. By resting on mutually angled, preferably perpendicular to each other, rod areas or sections is an additional stabilization of the support. It is furthermore preferred if the support section additionally rests at least partially on the corner connecting the rod sections.

In preferred embodiments of the invention, the holding portion is formed as a subsequent to the support portion tab which is bent back in the direction of the support portion and in the assembled state surrounds the angled end portion of the horizontal rod.

Particularly preferably, the fastening element has a latching element with a latching nose, wherein the latching lug is in the assembled state of the fastening element wall side of the longitudinal extension region of the horizontal rod. The locking lug is according to preferred embodiments designed so that it rests in the mounted state of the fastener on the side rail, preferably on the horizontal bar of the side rail, or in alternative embodiments only temporarily when mounted with the side rail, preferably with the longitudinal extension region of the horizontal bar of the side rail , is engaged and spaced in the assembled state of the fastener to the side rails.

Preferred fasteners are made in one piece. A one-piece production allows a special stability of the fastener. As a result, a cheaper and more accurate production is possible because manufacturing tolerances are minimized. In addition, no connection of several parts is necessary.

Particularly preferably, the fastening tab in the mounted state of the fastening element runs parallel to the plane spanned by the vertical bars and between the bars with a vertical interior side surface of the fastening tab rests against an imaginary interior side of the vertical bars adjacent surface. In such a fastener, the guide rail attached thereto runs so that it rests directly on the inside of the vertical bars. This concern causes increased stability of the guide rail and represents another Verkippsicherung.

In alternative embodiments, the fastening tab runs in such a way that, in the assembled state of the fastening element, it bears on the inside of a vertical bar on the inside with a vertical wall-side surface. It also achieves the stabilization effect described above.

In other embodiments, the fastening element has a locating tab which laterally adjoins the fastening tab and has an offset pointing in the direction of the side wall and, with the bent portion on one of the horizontal rods, rests on the inside in the assembled state of the fastening element. Compared to the embodiments described above, in this embodiment, the fastening tab is cranked and offset toward the interior. An attachment lug which directly adjoins the attachment lug also has an offset, with which the distance between the guide rail or attachment lug of the attachment element and the horizontal rod is compensated. This attachment tab rests on the inside of a vertical rod and thus also leads to a stabilization as stated above.

Preferably, a fastening element has one or more further bent or in a plane extending stabilization tab (s), the inner side or wall side abuts a vertical rod / rest.

Preferably, the support portion rests on the longitudinal extension region of the horizontal rod and the holding portion is formed by a portion of the support portion and vertically downwardly adjoining tabs, wherein at least two tabs present are, of which in the mounted state one wall side and another inner side to the longitudinal extension region of the horizontal rod and adjacent thereto.

Particularly preferably, the fastening element has a latching tab, which is attached to the fastening element and at least partially surrounds one of the vertical rods. As a result, a displacement of the fastening element along the horizontal bar, in particular along the longitudinal extension region of the horizontal bar is prevented. In addition, this locking tab provides further protection against tilting of the fastener.

Preferably, it is a locking tab, which is applied to the fastener and compared to the more stable fastener consists of a thinner flexible material, which has resilient properties, preferably, the locking tab is a leaf spring. Particularly preferably, both the fastening element and the spring element are made of metal.

In certain embodiments, a distinction can be made between a rear and a front fastening element, wherein the rear fastening element for releasably securing the rear, the rear wall of the household appliance facing the end of a guide rail is designed on a side rail, while the front fastening element according to the attachment of a front end of a guide rail serves on a side rail. Preferably, the locking tab extends at a rear fastening element on the inside of a rear vertical bar and engages behind the vertical bar partially from behind. A locking tab which engages behind the rear vertical bar of a side rail ensures that, when the telescopic extension is removed, sliding of the fastening element and thus the guide rail of the telescopic extension fastened thereto is prevented from the rear to the front. In a corresponding embodiment of a front fastening element, the spring element extends on the inside of a front vertical bar and engages around the vertical bar at least partially from the front.

According to certain embodiments, both fastening elements have a latching tab. In alternative embodiments, only one fastener on a guide rail on a locking tab, preferably only the rear.

According to the invention, a guide rail with two fastening elements described above. In the guide rail according to the invention, it is advantageous if a front fastener for releasably securing the front end and a rear fastener for releasably securing the rear end of the guide rail to a side rail is provided. The fasteners may in certain embodiments have the same components, where "equal parts" means that the respective components perform the same function. The components must not be designed identically or mirror-symmetrically for this purpose. In alternative embodiments, the fastening elements are different, ie they have elements with different functions. For example, a rear fastening element have a latching tab, while a front fastening element does not have such a latching tab.

The guide rail is, in certain embodiments, a guide rail of a telescopic full extension, i. the telescopic rail has a length when fully extended, which corresponds to more than twice the length in fully collapsed condition. According to other embodiments, the guide rail is a guide rail of a telescopic part drawer, in which the length in the fully extended state is slightly less than twice the length in the fully collapsed state.

Particularly preferably, the guide rail rests in the mounted state on the vertical bars of the side rails. A stabilization of the attachment of a guide rail with fastening elements on a side rail can also take place in that the fastening element or the fastening elements respectively encompass a region of a horizontal rod of the side rail and instead of the fastening element or the fastening elements, the guide rail itself on the front and rear vertical rods Side grille rests on the interior side.

In these embodiments, the attachment tab is parallel to the plane defined by the vertical bars and between the bars, with a vertical interior side surface of the attachment tab abutting an imaginary interior side of the vertical bars.

According to a further preferred embodiment, the two fastening elements are mirror-symmetrical to each other. The mirror-symmetric design allows a cost-effective production of the fasteners, as for the attachment of two guide rails on two opposite side rails a total of only two different fasteners must be made. That is, the right front and left rear fasteners and the left front and right rear fasteners are identical.

The fastening elements described above are preferred for fastening a guide rail of a telescopic extension or the above-described guide rail of a telescopic extension used with two fasteners in an oven as part of a system with telescopic rails for receiving or carrying a food support.

Usually, ovens each have a right and a left side rails, on each of which a telescopic extension with guide rail by means of two fasteners is attached. On the two extracts then a food support can be placed. It is preferred if the fastening elements are symmetrical to one another on a guide rail. As a result, a cheaper production is possible as described above.

FIG. 4:

a view of a guide rail with two mutually symmetrical fastening elements according to FIG. 1 ,

The left front fastener 1 in FIG. 1 is attached to a side rail 10 and serves to attach a guide rail 20. This figure shows the fastener 1 from the perspective of the inner wall of the household appliance from behind and outside. The fastener is fastened to a conventional side rail with two spaced-apart vertical rods 11 and horizontal rods 12 connecting them. The horizontal bars 12 have a central longitudinal extension portion 14 located inwardly of the vertical bars, and angled end portions 13 at their both ends fixed at their respective free ends to respective ones of the vertical bars 11 and substantially perpendicular to them standing vertical bars. In FIG. 1 In each case only one vertical and one horizontal bar is shown.

The fastening element 1 comprises a holding section 2, which surrounds the angled end portion 13 of a horizontal bar of a side rail 10 partially and extends around this bent. Next, the fastener on a support portion 3, which adjoins the holding portion 2 and with which it rests on the angled end portion 13 and longitudinal extension portion 14 of the horizontal rod 12. The fastening tab 4 runs perpendicular to the support section 3 and serves to attach the guide rail 20 to the fastener 1, wherein, for example, an attachment by welding the outer vertical surface 22 takes place with the section 4. The section 4 is parallel to the plane spanned by two vertical bars 11 and between the two vertical bars 11 of the side rail 10. In this embodiment, the guide rail 20 rests with its lower horizontal surface 21 on the support portion 3 of the fastener 1.

A stabilization against tilting of the fastener 1 and the guide rail 20 relative to the side rail 10 and in particular the horizontal bar 13 and 12 is additionally effected in this embodiment by concerns the vertical wall-side surface 22 of the guide rail to the horizontal rod 11 of the side rail.

The locking element 5 with a locking lug is located in the in FIG. 1 illustrated mounted state of the fastener is not on the longitudinal extension region 14 of the horizontal rod 12 but has a small distance from the longitudinal extension region of the horizontal rod. The fastener is slid onto the horizontal bar 12 of the side rail 10 by a movement parallel to the angled end portion of the horizontal bar 13 in the direction of the inner wall. In this case, the locking element 5 is pressed together with the portion which connects the locking element 5 with the holding portion 2, through a portion of the horizontal rod 12 down. The locking element 5 has for this purpose a latching nose with a corresponding insertion bevel. For the user, this results in a resistance that is exerted by the locking element 5 when fastening the fastening element 1 and is overcome by a corresponding slight effort.

FIG. 2 shows two rear fastening elements 101 and 201, which are used for fastening a guide rail 120 of a full extension ( FIG. 2a ) or a guide rail 220 of a partial extension ( FIG. 2b ) serve.

The two fasteners 101 and 201 are shown in a perspective view looking from the inner wall in the direction of the interior of the household appliance, it is in each case fasteners, which are attached from the left rear view of the opening of the household appliance on a left side rail 10. It is also in this illustration is a conventional side rails, with horizontal rods are arranged in pairs one above the other. The required for the attachment of the fasteners upper rod of the rod pair is respectively denoted by 12.

In the FIG. 2 each have a holding portion 102 and 202, which is formed by 3 tabs, wherein the two outer tabs on the inside run on the non-angled region of a horizontal bar 12 and the middle tab on the wall side. In FIG. 2a This holding section is hidden in the selected representation of the guide rail 120. A part of the holding section 102 or 202, which rests on a longitudinal extension region 14 of the horizontal bar 12, is simultaneously a support section 103/203.

Next both fasteners 101 and 201 have a stabilizing tab 108/208, which is below the support portion 103/203 on the respective fastener 101/201 and rests against the vertical rod 11 of a side rail 10. Another in FIG. 2 illustrated vertical rod is used to attach the side rail in the household appliance and has no effect on the attachment of the fastener 101/201 and the guide rails 120/220 on the side rails 10th

On the fastening straps 104/204, a respective guide rail is attached to a strap running perpendicular to the bearing sections 103/203. The fastening straps 104/204 extend parallel to the plane defined by the vertical bars 11 either between the bars 11 (FIG. FIG. 2a ), of which only one is shown, or wall side of the horizontal bar 14 in a plane between the horizontal bar 214 and the vertical bars 11 (FIG. FIG. 2b ). Both fasteners also have a locking tab 107/207, which consists of a thinner material than the fastener and the rear vertical rod 11 engages behind and rests against the inside of her.

The fastener 101 in FIG. 2a differs from the fastener 102 in FIG. 2b in that the guide rail 120 rests with its wall-side vertical surface 122 against the rear vertical bar 11 of the side rail 10. In FIG. 2b On the other hand, an abutment lug 206 is provided, which rests against the inside of the vertical bar 11, wherein the guide rail 220 does not touch the vertical bar 11. The attachment tab 206 extends laterally from the mounting tab 204 and is cranked. The fastening tab 204 is in FIG. 2b compared to FIG. 2a cranked and moved towards the interior. By the offset of the abutment lug 206, this distance is compensated for and the abutment lug 206 can abut the interior side of the vertical rod 11 and stabilize the fastener 201 against tilting.

The guide rail 220 in FIG. 2b belongs to a partial extract, which consists of two mutually displaceable rails; In contrast, the guide rail 120 is in FIG. 2a Part of a full extension with three mutually displaceable rails. This has the extract in FIG. 2a a comparatively greater thickness than the extract in FIG. 2b , This difference is due to the different positions of the attachment tabs 104 and 204 and the offset the attachment tab 206 in FIG. 2b or the direct concern of the guide rail 122 on the vertical rod 11 in FIG. 2a balanced.

FIG. 3 shows two front fasteners 301 and 401, with which, accordingly FIG. 2 , a guide rail 320 of a full extension ( FIG. 3a ) or a guide rail 420 of a partial drawer ( FIG. 3b ) is attached. These front fasteners 301 and 401 in FIG. 3 can look together with the appropriate fasteners FIG. 2 or other suitable rear fasteners.

In the FIG. 3 each have a holding portion 302/402, which surrounds the angled end portion 13 of a horizontal bar 12 of a side rail 10 partially. Next, the fastening elements 301/401 each have a support portion 303/403, which rests on the longitudinal extension region 14 of the horizontal rod 12. This support section 303/403 comprises a tab 309/409, which abuts the wall side on the longitudinal extension region 14 of the horizontal rod 12.

Both fasteners in FIG. 3 have a fastening plate 304/404 perpendicular to the support section 303/403, wherein FIG. 3a the guide rail 320 is fixed so as to rest on the support portion 303, while the guide rail 420 in FIG. 3b not lying.

In FIG. 3b the fastening tab 404 is cranked so that the vertical wall-side surface 422 of the guide rail 420 is offset toward the interior, as compared to the surface 322 in FIG FIG. 3a , As above FIG. 2 explained, this serves to compensate for the difference in thickness between a telescopic extract and a telescope part extract. Accordingly lies in FIG. 3a the vertical wall-side surface 322 of the guide rail 320 on the vertical rod 11 of the side rail 10, while in FIG. 3b an attachment tab 406 laterally adjoins the attachment tab 404, wherein the attachment tab 406 has a cranking pointing in the direction of the side wall and thereby abuts the vertical rod 11 on the inside.

FIG. 4 shows a side rail 10 with an attached guide rail 20. The fasteners 1 are mutually mirror-symmetrical and correspond to the in FIG. 1 In this embodiment, also the guide rail 20 rests with its wall-side vertical surface 22 on the vertical bars 11 of the side rail 10, while the fastening tabs 4 for fixing the guide rail 20 to the fastening elements 1 between the vertical bars 11 and parallel to the run from these rods spanned level.
