A side drawer fitting for a pull-out cabinet with the features of the preamble of independent claim 1 is known from DE 20 2007 013 448 U1 known. This is different from the one from the DE 20 2004 001 894 U1 known Seitenauszugbeschlag in that the linear guides are drawer underfloor guides. such Drawer Underfloor Guides, which are arranged in pairs at a height on either side of a drawer, are manufactured in large numbers and are available in high quality at reasonable prices. Their use also in Ausziehschränken leads to the result that a similar feel of all extendable parts of a furniture series, the high quality of the running behavior of drawers is transferred to Ausziehschränke. In addition, drawer underfloor guides can also be covered with a side drawer fitting as in drawers usual by the Ausziehrahmen on its side facing the respective side wall, resulting in a particularly high-quality visual impression of the extended Ausziehbeschlags.

Although it is from the DE 20 2007 013 448 U1 known side drawer fitting in not too large cabinet width suitable for normal loads. However, with wider cabinets and depending on the Ausziehrahmen further projecting attached slides, such as baskets, high lateral forces on the linear guides occur on the conventional drawer underfloor guides can not permanently accommodate.

From the EP 1 479 316 A1 a side extract fitting for a pull-out is known, in which a Ausziehrahmen of rigidly interconnected horizontal beams and vertical beams is mounted above a linear guide on the side wall of a body of the Ausziehschranks and below via a further linear guide at the bottom of the body. In the upper linear guide in the form of a ball telescope rail, the telescoping parts are supported by balls in the vertical direction to each other. The lower linear guide has revolving rollers around vertical axes, which engage in a downwardly open U-shaped rail of the lower horizontal support of the Ausziehrahmens. The rollers are mounted on an intermediate part of the lower linear guide, which in turn is mounted extendable to a mounted on the bottom of the body part via a ball guide.

From the EP 1 615 529 B1 is a corner cabinet with sliding mounting units known. For a mounting unit while a sliding and pivoting guide is provided which allows withdrawal of the mounting unit from the corner cabinet and en pivoting of the mounting unit about a vertical axis. The sliding and pivoting guide comprises an angle frame pivotally mounted on a side wall of the corner cupboard about the vertical axis with an upright stand spar and with an angle beam projecting horizontally from below the upright and a side front frame holding a cabinet front and the is slidably mounted below with a side frame part with the interposition of a telescopic rail at the lower angle spar of the pivot guide and engages with an upper guide rail on top of the stand handle rotatably mounted roller displaced. Furthermore, a laterally projecting roller is provided at the rear end of the guide rail, which engages displaceably in a mounted on the side wall, diagonally arranged guide rail. This guide role cooperates in the pulled-out position of the assembly with the role to extract the limit. Thus, the side front frame is guided at the top by two rollers that absorb tilting moments of the mounting unit. Horizontal loads are transmitted to the angle frame.

From the WO 2008/135270 A1 is a fitting for a corner cabinet with a pull-out one-piece tray known. The tray is supported on its underside in two spaced points by support arms. Both support arms are in turn supported movably on a carcass of the corner cupboard. A support bearing for the one support arm is arranged on a side wall of the body of the corner cabinet and has a linear guide which defines a horizontal extension direction for the support arm. In order to support the lifting forces resulting from the length of the support arm in the support bearing, a supporting roller running parallel to the linear guide and offset in height relative thereto is provided. It can also be provided several support rollers. Thus, the linear guide may be a conventional pull-out rail which is arranged in a profiled sheet. A carriage on which the support arm is rigidly mounted, can then be performed on the profiled sheet on the one hand via the linear guide and on the other hand via support rollers, which are supported about vertical axes of rotation rotatably supported on the carriage support rollers on edge vertical legs of the profile sheet. The support rollers absorb the tilting moments around the guide direction of the linear guide. The linear guide absorbs both vertical forces and tilting moments about the other horizontal direction.

From the EP 0 806 163 A1 is a device for storing a displaceable in a cabinet element and pivotable fixture known. This device has, in addition to a first guide part provided in the region of a lower horizontal support of the installation part, which consists of a linear guide, a guide rail fixedly attached to a side wall, which comprises a first linear guide track. Along the guide track first guide elements in the form of rotatable about vertical axes of rotation rollers are movable, which are fixed to the mounting part. At the guide rail are second Guide elements in the form of also rotatable about vertical axes of rotation mounted rollers through which a second linear guide track is guided, which is arranged on the mounting part. By this further guide part together with the first guide part, the built-in part can be moved from a retracted position to an extended position and vice versa.

OBJECT OF THE INVENTION

The invention has for its object to provide a side drawer fitting with the features of the preamble of independent claim 1, which has a significantly improved running performance over conventional side drawer fittings and yet is also suitable for wider Ausziehschränke.

SOLUTION

The object of the invention is achieved by a side drawer fitting with the features of independent claim 1. The dependent claims 2 to 14 are directed to preferred embodiments of the invention Seitenauszugbeschlags. Claim 15 claims a pull-out cabinet with a carcass and with a cabinet on a side wall of the carcass horizontally extendable mounted on a side drawer fitting according to the invention.

DESCRIPTION OF THE INVENTION

In a side extract fitting according to the invention with a Ausziehrahmen having at least two vertically superimposed and rigidly interconnected horizontal support, and having at least two linear guides, each having a first connection element for attachment to a side wall of a body of a Ausziehschranks and a relative to the first Ausziehelement linearly guided second Having connecting element for attachment to one of the horizontal support, at least one support bearing for supporting acting on the Ausziehrahmen horizontal transverse forces on the side wall is provided. The support bearing comprises a support roller which is mounted on a base member to be fixed to the side wall about a vertical axis of rotation to be aligned is rotatably mounted and engages with mounted side drawer fitting in a top or bottom open U-rail on one of the horizontal support.

Even with a relatively simple storage of the support roller and considerable lateral forces acting on the support roller forces this does not affect the running behavior of the side drawer fitting according to the invention. It is assumed that the roller has a somewhat, but clearly smaller diameter than the clear width of the U-rail between their parallel legs. The support roller can therefore always rest only on one of the two legs of the U-rail in the lateral direction. The respective horizontal support on the support roller and thus on the side wall of the extension cabinet is then supported via this leg in addition to the linear guide provided between the horizontal support and the side wall. Transverse forces, such as those associated in particular with tilting moments, are thus not removed in the case of the side-pull fitting according to the invention or at least beyond a certain size only via the linear guides, but via the support bearing (s). As a result, the linear guides can be selected from the standpoint of good pull-out performance, without having to consider the lateral load capacity. Thus, according to the invention drawer guides can be used as linear guides, which are available as sophisticated mass-produced high quality. Concretely, the drawer guides can be drawer underfloor guides, which can be substantially obscured even in the extended state of the side drawer fitting by panels.

It is preferred in the new side drawer fitting, if one of the support bearing is provided on the lowest horizontal support of the Ausziehrahmens and one of the support bearing on the top horizontal support of the Ausziehrahmens, because here the largest lateral forces, once towards the side wall of the body of Ausziehschranks and once from the sidewall away. If more horizontal beams are present, can also be provided for these support bearings, although they are not so important, even if additional linear guides are provided for this horizontal support.

In a specific embodiment of the side drawer fitting according to the invention, at least the horizontal beams on which the linear guides are to be fastened, with a continuous profile, form a downwardly open U-rail for receiving the respective linear guide and the upwardly open U-rail for engaging the support roller , These Accordingly, the embodiment preferably uses drawer bottom guides as linear guides which are at least partially obscured by the downwardly open U-rails of the horizontal beams. The support rollers of the support bearings engage in upwardly open rails, which can run in the same vertical planes as the upwardly open U-rails for receiving the linear guides. The lateral engagement opening between the U-rails can be comparatively narrow.

The contiguous profile of the horizontal beam with the two U-rails may have only at right angles abutting straight profile areas and thus convey a flat box or rectangle bar-shaped straightforward visual impression.

The downwardly open U-rail may have an inwardly projecting, that is horizontally projecting in front of the opening of the U-rail retaining edge. Fastening elements for fastening the second connecting element of one of the linear guides in the vertical direction on the horizontal carrier can be supported on this holding edge. With these fasteners, the linear guide in the downwardly open U-rail of the respective horizontal carrier can be set in a particularly simple manner.

Front holding elements for a cabinet front of the pull-out cabinet can be anchored in the downwardly open U-rails next to the respective linear guide. In this case, each front holding element is preferably adjustable between a front connecting part element and an anchoring part element detachable therefrom in order to align the front with respect to the body of the extending cabinet.

In the side extract fitting according to the invention it is provided that the support roller of each support bearing is always arranged in its associated U-rail, so only within this rail moves and not about the Auszugweg the Ausziehrahmens emerges from this U-rail or in the U Rail enters. This is also a prerequisite for the support role when unrolling on the legs of the U-rail does not affect the pull-out behavior of the side drawer fitting according to the invention.

Thus, the support roller is always located in the U-rail, the base element of the support bearing for attachment to the side wall in a pull-out in the front

Area of the first connection element of one of the linear guides provided. Specifically, the base element of the support bearing can be latched onto a fastening element, which is provided for fastening the first connection element of the respective linear guide on the side wall. That is, for attaching the support bearing the snapping his base member extends to the fastener. This step is usually performed with already mounted on the second connection element of the respective linear guide horizontal carrier with simultaneous insertion of the support roller in the associated U-rail on the horizontal support. For latching the base element onto the one fastening element, a latching opening in the fastening element is typically sufficient.

The fastening element for fastening the first connection element of the respective linear guide on the side wall may be an angle plate welded to the first connection element. Typically, two such angle plates are provided at a distance along the first connection element of the linear guide.

The horizontal supports of the pull-out frame of the side-pull fitting according to the invention are typically rigidly interconnected by at least two vertical supports. In particular, the vertical beams are butt welded from above or below to the horizontal beam. This also contributes to the simple unfussy optical impression of the side-pull fitting according to the invention.

The vertical supports are preferably formed from sections of a profile of rectangular cross-section, wherein mounting openings are provided in the vertical carriers for slides only on their sides facing each other. The main surfaces of the vertical support are not visually disturbed by the mounting holes.

In a pull-out cabinet according to the invention with a body and with a cabinet front, the cabinet front is mounted horizontally extendable with a side drawer fitting according to the invention on a side wall of the body. Together with the front of the cabinet, the pull-out frame and any slides attached or attached to the pull-out frame are moved. The pull-out cabinet according to the invention has an excellent running behavior with cost-effective manufacturability. The cost of the support bearing according to the invention for receiving the transverse forces while the cost benefits resulting from the usability of drawer guides as linear guides, at best to a small extent. at the pull-out cabinet according to the invention, the drawer slides can be equipped in a known manner with Selbsteinzügen and the like facilities.

DESCRIPTION OF THE FIGURES

Fig. 1 and Fig. 2 show a side drawer fitting 1. The side drawer fitting 1 is in Fig. 1 except for slides that are attachable to a pull-out frame 2 of the side drawer fitting 1, fully illustrated. For attaching the slides 2 mounting holes 4 are formed on the facing inner sides of two vertical beams 3 of the Ausziehrahmens. The vertical beams 3 are based on portions of a profile of square cross-section and are butt welded to a horizontal top and a horizontal bottom of two adjacent horizontal beams 5 of the Ausziehrahmens 3. The horizontal beams 5 are profiled sheets with rectangular adjoining profile areas. The horizontal beams 5 each form an upwardly open horizontally extending U-rail 6 and a downwardly open horizontally extending U-rail 7 in a main plane of the Ausziehrahmens 2, in which extend the vertical support 3. The downwardly directed opening of the U-rail 7 is reduced by an inwardly projecting retaining edge 8. Fastening elements 9 and 10 and an anchoring partial element 11 of a front holding element 12 provided on each horizontal support 5 are supported on this retaining edge 8. In the Fig. 2 including their anchoring elements 11 omitted front retaining elements 12 are made in addition to the anchoring part element 11 each one Front connection element 13 which can be fastened to a cabinet front and which can be fixed relative to its relative position adjustable to the respective anchoring part element. The fastening elements 9 and 10 are each used for fastening a connecting element 14 of a linear guide 15, which is designed in particular as a commercial drawer floor guide. The connecting element 14 of the linear guide 15 is fixed with the fastening elements 9 and 10 respectively in the downwardly open U-rail 7 of the horizontal support 5. The connection element 14 of the linear guide 15 is rectilinearly guided relative to a further connection element 16 of the same linear guide, wherein an intermediate element 17 is provided in order to increase the possible extension path of the connection element 14 with respect to the connection element 16. To the connecting element 16 fasteners 18 are welded in the form of angle plates with its horizontal leg, while in their vertical leg mounting holes 19 are provided for screwing to a side wall of a body of a Ausziehschranks. The fastening element 18 lying further forward in each case also serves to support a base element 20 of a support bearing, which is formed between the side wall of the body and each of the two horizontal beams 5. The support bearing in each case comprises a support roller 21 which is rotatably mounted on the base element about a vertical axis of rotation and which engages in the upwardly open U-rail 6 of the respective horizontal support 5. The support roller 21 has a slightly smaller diameter than the distance of the vertical legs 22 and 23 of the U-rail 6. That is, it always rests only on one of the two legs 22 or 23, depending on whether between the side wall and the Ausziehrahmen 2 at the height of the support bearing the Ausziehrahmen 2 on the side wall pressing or withdrawing from this lateral forces. In any case, these transverse forces are transmitted from the horizontal support 5 on the support roller 21, from there to the base member 20 and from there via the fastener 18 on the side wall of the body of Ausziehschranks and derived in this way. The base element 20 is designed so that it can be mounted by simply latching on the fastening element 8, wherein it is supported with a region 24 between the connecting element 6 and the vertical leg of the fastening element 18 and with a latching nose 25 in a latching opening in the fastening element 18 engages.
