Description

The The invention relates to a pull-out guide for drawers with a running rail according to the preamble of claim 1.

From the DE 84 31 055 It is known to herauszubiegen the fishing hook from the material of the track. Especially with very wide drawers, which have a high mass, the problem arises that the fishing hooks can bend.

The generic EP 1 147 725 further discloses to form the fishing hooks as separately formed to the running rail and height adjustable arranged elements to adjust the inclination of a front panel of the drawer. Also, the hooks disclosed in this document are only partially suitable for fixing very heavy drawers.

From the DE 36 41 325 A1 It is also known to install a spacer between a drawer rear wall and a fishing hook to use a running track for smaller, not really adapted to their dimensions drawers. To compensate for tolerances within the current production of a drawer / Ausziehführungsserie this spacer is not suitable.

In front In the above background, it is a first object of the invention, with simple structural means a particularly stable fishing hook design to realize.

About that addition, a constructive solution for the problem to be created, tolerance-based game between compensate for a catch of a track and a drawer to be able to.

The Invention has the task, the two problems mentioned first each in a simple constructive way to fix.

The Invention solves the first task by the subject of claim 1. An alternative solution is used 20 indicated.

The The invention also provides the subject matter of the claim 4, which solves the second task.

To The subject matter of claim 1, it is possible, the fishing hook fundamentally different - in particular more stable - interpreted as the running track. So he can in particular from a harder Material are made as the running rail and / or but off a thicker material, which makes it easy to to increase the strength of the arrangement. Especially preferred the effect of these two measures is combined, to arrive at a particularly advantageous embodiment

It is conceivable to set the catch hook in various ways on the running rail. Furthermore, any position in the longitudinal direction of the track for the fishing hook is conceivable. 20 shows a running rail, in which a plurality of in the main extension direction of the running rail (X) offset from one another means - in particular windows - are provided for fixing the separate fishing hook, which makes it possible in the simplest way, one and the same rail for setting different deeper or longer To use drawers, which may be useful, for example, to realize in a piece of furniture with a deeper full extension extending only over part of the depth of the cabinet drawer. This variant is considered separately as an invention and as a development of the other disclosed inventions.

Especially simple and safe is a fixing to a window-like opening the running rail, in which the fishing hook is inflected and in which he clamped by bending corresponding projections and / or embossed.

Especially preferred is the compressive setting on a window in the Running track realized as this is a cost-effective way the assembly is, which also offers the already mentioned advantage, that the materials do not heat up, so that the rails usually do not bend or warp during assembly.

alternative or optionally, the fishing hook also by means of other fastening devices like screw / nut combinations, by means of clinching, riveting or by gluing, welding or soldering be determined on the track.

It is particularly conceivable, the fishing hook of a stainless material how to manufacture a stainless steel, so that the stability also permanently guaranteed.

to Avoidance of too much play between the track and the drawer or drawer rear wall is according to claim 4 provided, at least one spring element or at least one elastic To provide compressible element on the fishing hook, which is the drawer rear wall resiliently supported on the fishing hook.

This spring element constitutes an advantageous further development of the invention. However, it forms also for a separate invention, with this fuse element the problem of too large -. B. leading to a rattling or troubled run - game between the drawer and the track is solved.

To A particularly advantageous variant of the invention is further advantageous for stiffening the fishing hook on the fishing hook Stabilization element and / or a support element such as a support rib or provide a support leg. Also this variant on the one hand forms an advantageous development of the invention, On the other hand, it can also be considered as a separate invention to be viewed as.

1 shows a running rail 1 an otherwise not shown here, preferably telescopic drawer slide for a drawer 2 (See in this respect the one ande res embodiment concerned 15 ), which may be formed in any desired manner and typically at least one to be determined on a furniture body furniture body rail and to be determined on the drawer slide rail 1 of the 1 and at least one bearing, in particular a rolling bearing (also not shown here), between the furniture carcass rail and the running rail 1 having. Optionally, the pull-out guide may comprise further elements such as a middle rail.

To a drawer 2 on the track 1 it is on the track 1 a fishing hook 3 arranged or formed.

To 1 is the catch hook 3 as a running track 1 formed separate element, which on the running rail 1 is fixed. This offers the particular advantage that for the fishing hook 3 a more stable design can be chosen than for the rest of the track 1 ,

So it is conceivable, the fishing hook 3 made of a different material - in particular of a harder material - to manufacture than the running rail 1 to the stability of the fishing hook 1 to increase.

Alternatively or optionally, it is conceivable, the fishing hook 3 made of a thicker (thicker) material than the track to provide it with increased strength. The fishing hook 4 but can also be provided with stiffening elements such as ribs and / or with support elements which him to the running rail 1 support.

The track 1 is after 1 formed as a non-circumferentially closed hollow profile, which is made of a sheet metal strip which is bent into a rail shape having a substantially rectangular cross-section, wherein a longitudinal slot 4 remains. The track 1 is at her from the longitudinal slot 4 facing away from the bearing side 5 flattened designed to put a drawer on top of them to be able to lay.

In the landing page 5 is a window-like opening 6 trained, laying down the fishing hook 3 on the track 1 serves and is designed.

The opening 6 is close to a free end of the track rail 1 educated. Next to the opening 6 here is an optional recess 7 provided at the free end of the track rail 1 next to the opening 6 is formed and located in the bearing side 5 extends into it.

The fishing hook 1 is so in the opening 6 can be used and in the opening 6 clamped or compressible, that he from the longitudinal slot 4 opposite side of the track as here substantially rectangular / L-shaped hook area 8th projecting, which is adapted to engage in a corresponding opening of a drawer to this on the running rail 1 set and fix.

This will be after 1 realized in that the preferably bent from a metallic sheet metal catch hooks 3 has a Z-like, stepped shape, wherein in the mounted state, a leg 9 of the fishing hook 3 in the opening 6 engages and being the free end 13 of the thigh 9 from the inside out into the recess 7 is bent back.

In addition, the catch hook 3 to 1 lateral support legs 10 . 11 in the area of his middle thigh 12 on the one in the hook area 8th bent away direction, and in the mounted state outside on the support side 5 support.

Through the interaction of the support legs 10 . 11 and the thigh 9 with the bent free end 13 which is in the recess 7 engages, is the catch hook 3 easy to move and twist on the rail 1 established.

The free end of the hook area 8th can be slightly tapered to facilitate the sliding of a drawer.

Will the fishing hook 3 made of a steel material, it has a particularly high stability and is also for fixing heavy drawers and in particular for securing the same against lifting from the running rail 1 secured in a simple manner.

The embodiment of 2 corresponds largely to the embodiment of 1 ,

As in 1 is provided that the support legs are formed chamfered, wherein the support legs 10 and 11 of the embodiment of 2 at their beveled ends in web-like projections 14 . 15 pass over when mounting on the outside of the track rail 1 on their overlay side 5 over the free end of the track in the area of the recesses project and into the recess 7 bent down. They replace the bent end with it 13 of the thigh 9 , Otherwise, the design and function of this embodiment corresponds to the 1 ,

Of the embodiment of 1 differs the embodiment of 3 by being attached to the bent end 13 at least one advantage 16 connects, the recess 7 completely penetrated from the inside to the outside and on the outside of the support side 5 on the pad side 5 is bent back so that the securing effect of the bent end 13 for firmer securing of the hook 3 is increased again in a simple manner.

Preferably, the bent end is at least one or more of the protrusions 16 Mistake. The projections 16 offer a simple constructional measure to increase the security effect and to optimize and fix the catch hook 3 on the track 1 ,

Deviating from 1 is in the embodiment of 3 provided, the support legs are not in the hook area 8th bend away from the direction, but the support legs 10 and 11 just lean in extension of the level of the thigh 12 from the side on the track.

The embodiment of 3 But could also with support legs on the type of 1 or 2 be provided.

While the fishing hook of the embodiments of the 1 to 3 is bent in each case from a sheet metal blank, according to the embodiment of the 4 provided, the contour of the fishing hook 3 to cut directly from a correspondingly thick sheet, the main plane parallel to the main extension direction of the track 1 is aligned and not like after 1 to 3 perpendicular to this direction.

The fishing hook 3 again has an L-shaped hook area 8th and is at his from the hook area 8th opposite end with a locking leg 17 provided, which has a slot, wherein the securing leg 17 for engaging in a window-like opening 6 is designed. The fishing hook 3 is used during installation in the window-like opening 6 guided and then laterally verscho Ben, until the material of the bearing side 5 the track 1 in the slot 18 intervenes.

Then there will be a free end 19 of the fishing hook turn into a recess 7 at the free end of the pad side 5 bent, what the catch hook 3 against a displacement in the direction of the running rail similar to the embodiments of the 1 and 3 guaranteed.

The embodiment of 4 is characterized by a particularly stable hook area 8th out, which offers particular resistance to a bending.

It is also conceivable the fishing hook 3 attach to the track in another way.

It will be after 5 proposed for attachment of the fishing hook 3 a clinch connection 20 to use which is a support leg 21 of the fishing hook 3 on the bearing side 5 sets. In the area of the support leg 21 is this fishing hook 3 flat or flat. In the area of the hook, ie in the actual hook area 8th on the other hand, the fishing hook on a trough-like contour, what the stability of the fishing hook 3 again increased in a simple manner.

To 6 is provided, the fishing hook by means of a soldering or welding process on the support side 5 to determine the running rail. The fishing hook 3 points here again in the hook area 8th the trough-like contour on and in the area of the support leg 21 a planar geometry, which facilitates the welding or soldering on the track in a simple manner.

To 7 is again provided, the support leg 21 that with a window or an opening 22 is provided by means of a kind of Befestigungsniet 23 with riveted passage through wobble rivets on the support side 5 the track 1 to fix. To 7 indicates the hook area 8th also a flat contour again.

How out 8th can be seen, the fishing hook 3 Also be cut from a bolt that is bent into a hook shape, it lends itself to the fishing hook 3 on the pad side 5 the track 1 to weld.

Also after 9 is provided, the fishing hook 3 welding on the bearing side 5 the track 1 set.

Notwithstanding the above figures but is provided, the actual hook area 8th again directly from the material of a sheet to cut and this by type 4 essentially - ie in the predominant surface area - parallel to the main extension direction of the running rail 1 align, with the support leg 21 is bent out of the hook area and where the hook area 8th towards the side a trough-like contour 24 is bent, which attaching the catch hook 3 relieved at a corresponding drawer box contour.

To 10 is provided, the fishing hook 3 Assign a tolerance compensating spring element.

This spring element is used to generate a biasing force between the fishing hook 3 and the drawer 2 ,

To 10 is first again a separate catch hook 3 on the track 1 fixed, which is bent in stepped form.

The fishing hook 3 has lateral bars 25 . 26 on which of a spring wire of a wire spring 27 are entwined, with the wire spring 27 with a temple area 28 on the track 1 supported, and wherein the wire spring also spring legs 29 . 30 which, in the assembled state - as shown 12a visible - at the drawer 3 support, so that between the running rail or the fishing hook 3 and the back of the drawer 2 a bias is generated by spring action.

Instead of a wire spring, this spring effect could also be generated by another resilient or elastic element, such as by a meander-shaped curved leaf spring 31 (please refer 11 and 12b ), which is between the thigh 12 of the fishing hook 3 and the rear wall of the drawer 2 supported or but for example by a coil spring 34 ( 13 ), the z. B. resilient between a stop pin or web 32 a preferably bent from a pin or pin fishing hook 3 and a disc 33 at the fishing hook 3 acts. The coil spring 34 pushes the disc 33 against the drawer ( 15a ).

It is conceivable, on the one hand, the coil spring 34 with one of its ends on a dock 32 or by type of 14 the catch hook made of a bolt or pin 3 To provide at its free hook area end with a thread or to bend it from a set screw and the thread 35 a knurled nut 36 unscrew, which has an axially adjustable stop for the coil spring 34 forms ( 14b ). To realize an anti-rotation, the knurled nut with clamping part or the clamping part is provided with a non-metallic insert. Alternatively, the lock nut can also be completely off Plastic are manufactured. An execution as PAL mother or the coating with a security lacquer is also conceivable.

Such can easily by adjusting the nut, in particular the knurled nut 36 on the drawer over the glass 33 acting spring force adjusted or preset.

How out 12 and 13 it is also conceivable, the end of a threaded pin not on the running rail 1 to weld, but it by a formed by webs axially enforceable window web opening 37 to stick and compress this arrangement if necessary in addition.

15 shows how the on the jetty 32 or at the mother 36 supporting coil spring between the fishing hook 3 and the drawer rear wall of the drawer 2 acts. The 15a shows the non-adjustable variant and the 15b shows the adjustable variant of the hook with length compensation.

It is thus possible in a particularly simple manner, the options "spring action between the fishing hook 3 and the drawer rear wall "and" separate catch hook 3 to increase stability "together.

But it is also conceivable to provide only one of these two inventions, ie, the spring element can also be in a material of the running rail 1 self-curved fishing hook 3 are used (not shown here) and the separate catch hook element 3 , which is made separately from the track, can also be used without the spring element. Particularly advantageously, the effect of these two measures is combined.

To 16 to 19 is provided, the fishing hook 3 directly from the material of the track to manufacture / bend.

This is made of the material of the track 1 in the area of the bearing side 5 a web-like section cut out and in the form of a catch hook 3 bent so that an L-shaped fishing hook of the material of the running rail at the side remote from the longitudinal slot outside of the support side 5 protrudes. This forming a fishing hook 3 is known per se.

To optimize the strength effect, however, it is also provided laterally on the fishing hook 3 a bridge made of material of the track rail 1 to leave that as a support leg 38 acts and extends in the direction away from the hook area direction.

Common to the embodiments of the 16 to 19 in each case that directly from the material of the running rail, a reinforcing element is bent out of the material of the running rail.

To 16 this reinforcing element is a single support leg 38 , To 17 on the other hand is provided, two of the support legs 38 , which are laterally on the thighs 12 connect the L-shaped hook member to punch out material of the track rail freely and bend freely, which increases the support effect again and the C-catch hook 3 stabilized.

According to the embodiments of the 18 and 19 is provided, the support leg 38 not sideways to the sides of the thigh 12 of the hook area 8th connect, but a support leg 38 directly from the thigh free to cut, with z. B. by means of two parallel cuts in the region of the leg 12 extending over the end of the thigh 12 in the edition page 5 extend into it, the support leg / support bar 39 formed at an acute angle at an angle of less than 95 ° to the support side 5 is formed, and which is not parallel to the leg, but this obliquely at the free hook end of the free area 8th supported on the opposite side.

By embossing contours 40 . 41 extending into the area of the free end of the hook area 8th can extend into it, it is possible, the supporting effect of this support leg 39 to increase in a simple way.

The embodiments of the 17 to 19 is common that they are particularly cost-effective, but still have increased resistance to fishing hooks without support elements or support legs.

The 20a to 20c show one on the principle of a bayonet closure - ie with a specifying rotary motion and here additionally at different positions of the track 1 fixable catch hook 3 ,
