Abstract

The device has a locking unit and an actuator (11) including stop surfaces, which absorb impact during a coupling process for a coupled movement of furniture parts during a movement operation. The movement operation represents a controlled operation mode for the movement of the furniture parts relative to one another. One of the stop surfaces is formed at a spring tongue (13), and a recess is provided in a spring direction behind the stop surfaces for providing spring deflection of the stop surfaces.

Description

The invention relates to a device for influencing the movement of relatively movable furniture parts according to the preamble of claim 1 and a drawer slide.

State of the art

Devices of the type described in the introduction have already become known in various embodiments.

For example, from the Austrian patent AT 393 948 B discloses a locking device for drawers, in which on each side of the drawer an extractor rail fastened to the drawer and a mounting rail fastened to a furniture carcass is provided. Load-bearing rollers are stored between the rails. The locking device comprises a body side mounted under spring action Kippsegment having a receiving slot for a mounted on the drawer driving pin. The tilting pad is slidably mounted on the furniture body in the pull-out of the drawer and is guided along a guide track, which is formed by a groove or the like and the one straight rear portion, followed by an arcuate front portion connects. In this way, a memory state can be set, which is taken when pulling out a drawer, and from which the drawer is pulled into an end position when re-entering the drawer.

Meanwhile, various embodiments of such automatic catchment, inter alia, with damped indentation on the market.

Intended is a particularly gentle pulling of drawers in an end position.

Purpose and advantages of the invention

The invention has for its object to provide a device of the type described in the introduction, with which it is possible to further improve a uniformly smooth and gentle retraction movement.

This object is solved by the features of claims 1 and 11.

In the dependent claims advantageous and expedient developments of the invention are given.

The invention relates to a device for influencing the movement of relatively movable furniture parts, in particular for drawer guides, wherein the furniture parts can move freely in a first movement section, wherein a coupling device for connecting the movable furniture parts for a coupled movement in a second movement section is provided, and wherein the coupling device has stop surfaces, the absorb the substantial impact in a coupling process for a coupled movement of the furniture parts.

The stop surfaces should relate to such stop surfaces, which cooperate in the normal regular operation of the mutually movable furniture parts. To delimit from this are areas that meet when the coupling device "out of step" is advised, and is transferred by a special movement back to the normal operating state. A regular operation is, for example, an operation in which the abutment surfaces meet and then a furniture part is moved from the impact position to a predetermined position.

The essence of the invention lies in the fact that at least one stop surface is formed on a spring member having a recess located behind it in a spring direction for providing a spring travel for the stop surface. By this measure, the meeting of stop surfaces is designed so that it runs quieter and softer. The clashing parts, which are associated with the mutually movable furniture parts are, so to speak, gently intercepted, so that e.g. the start of automatic retraction of one furniture part compared to the other furniture part, e.g. pulling a drawer into a carcase is less noticeable in both an acoustic and a haptic sense.

The abutment surfaces which meet in the regular operating state, are preferably oriented so that by "positive engagement" a power transmission in the direction of movement is possible. For example, an abutment surface is formed, for example in the form of a shoulder, such that the other abutment surface is substantially perpendicular or in a comparatively narrow angular range of, for example, smaller +/- 30 ° in the vertical direction on the stop surface moves.

The spring member may be configured in various ways. In a preferred embodiment, the spring member comprises at least one spring tongue. The tongue can deflect when hitting a striking part of the device in the spring in the underlying recessed area and thus make the contact process gentle. In principle, several spring tongues can be connected in series. It is also preferred if the spring force in the direction of impact for the series-connected spring tongues increases in particular continuously. For example, the first spring tongue is soft and thin and the last comparatively harder and thicker.

Also conceivable is a spring member in the form of a spring bridge which can spring into a lying behind the bridge area. Also in this embodiment, several superimposed bridges are possible as in the spring tongues.

Also, one or more spring tongues can be combined with one or more spring bridges.

In a further preferred embodiment of the invention, the spring member comprises a particular rigid spring surface with a spring element in the underlying recess. The spring element may be in the form of a spiral or leaf spring. For example, the spring surface may be formed on the coil spring so that when the abutment surfaces of the abutment surfaces, the spring surface can escape by the compression of the coil spring.

Also conceivable is a rigid stop surface in combination with an elastic rubber element behind it lies.

In principle, the spring members in the form of a spring tongue or spring bridge may consist of a spring element which is inserted into a base part. The spring element may be made of metal or plastic.

Also preferred is an embodiment of the invention in which on a first device part of mutually movable device parts, a driver, e.g. a web element and at a second device part a coupler for receiving the driver is formed, wherein the driver and / or coupler at least one erfindunsgemäßes spring member is provided. In the coupling movement of the driver is preferably caught by the coupler when it moves toward the coupler. The spring members of the invention dampen the impact of the driver on the coupler. This can be done by applying either to the coupler or to the driver or to both elements e.g. a spring tongue is provided.

As a further advantageous embodiment of the invention, a further surface on the coupler is provided such that the driver between this surface and a stop surface which yields resiliently, can be clamped to the coupler. By this measure, the device parts to be coupled are coupled together without play, which supports a defined retraction movement.

It is also proposed that, in addition to a first resiliently yielding stop surface, a further stop surface on the coupler which yields resiliently is provided such that the driver can be clamped between the first and the further stop surface on the coupler. The more resilient yielding stop surface on the coupler, in particular with respect to the first resilient abutment surface arranged so that the driver is clamped in the coupling state between these resilient abutment surfaces. In principle, further resilient and / or non-resilient yielding abutment surfaces on the coupler are conceivable, so that the driver in the coupling state between several stop surfaces come into contact or can be trapped.

The design of the coupler should suitably be applied to the driver, e.g. be matched a web element, so that predetermined portions of the driver initially cooperate with the spring member and optionally create additional surfaces of the driver or the coupler to each other to obtain a reliable and secure connection of the coupler with the driver, if in the second movement section, the movable Furniture parts are coupled together via this connection.

The procedure according to the invention moreover has the advantage that manufacturing tolerances can be compensated for by the use of a spring element to a certain extent, since the at least one spring element provides elastic compensation. For example, without limitation of functionality, it can be tolerated to some extent when the driver has positional deviations from the manufacturing with respect to the coupler.

In order to obtain cost-effective, yet reliably functioning components, it is further proposed that the coupler is designed in one piece with at least one spring member. Advantageously, the coupler is made with the spring member made of plastic. In principle, however, it is also possible to provide a spring element in the form of an insert on the coupler. For example, a leaf spring is inserted, which is clamped on one side and thus forms a spring tongue. This can still be done during the production of the coupler made of plastic, for example in realize the injection mold or as a posterior element.

The spring characteristic of a spring member can be influenced in addition to the material selection in an advantageous manner by their geometric design. For example, a tongue is provided with thickenings, apertures or slits, which can be specifically obtained yielding or stiffer points. The tongue may also have a thick base and become thinner towards the tongue end.

In a further preferred embodiment, the coupler is pivotally mounted on a device part. Conveniently, a pivot position represents the coupling position with the driver and the other is the state in which a collection energy for the retraction of a furniture part is stored in a predetermined position.

In a further preferred embodiment, the coupler is arranged on an automatic movement with a memory state, wherein the storage state is released by a movement of the coupler upon impact of the driver, which was brought about by a movement of a furniture part.

The device according to the invention may e.g. be used for a drawer slide, in which the device is positioned between a body rail mounted on the cabinet rail and a drawer rail attached to a drawer.

Description of the embodiments

Figure 1 shows obliquely from above a piece of furniture 1 a, which comprises a body 1 and a drawer 2 movably guided therein. The arranged in the lower region of the body 1 drawer 2 is shown in the open or withdrawn state, wherein the mutually movable furniture parts 1 and 2 via a pull-out or a drawer slide 3 relative to each other are displaced. In the body 1, a further drawer, not shown, can be accommodated in the same way via a further drawer slide 3a. The drawer 2 is movable according to the double arrow P1 relative to the body 1. To guide the movement of the drawer 2, a similar drawer slide 3 is provided in the lower region of both sides of a drawer bottom 2c upwardly projecting drawer slide 3, wherein in Figure 1 only on a carcass inside the drawer slide 3 or 3a can be seen.

The drawer slide 3 shown in FIG. 1 corresponds in principle to the drawer slide 3 shown in FIG. 1. The drawer slide 3 can in principle be designed, for example, for a full extension or partial extension and, in the example shown, comprises a cabinet rail 4, which has body angles 4a, 4b on the carcass 1 is firmly attached, a middle rail 5 and a drawer rail 6, which on the drawer 2 in each case in the lower region of the corresponding drawer 2 a is attached. The rails 5 and 6 are guided according to a double arrow P2 to each other or the middle rail 5 to the carcass rail 4 slidably.

For damping the insertion movement of the drawer 2, the drawer guide 3 comprises a damper 8, which is mounted in a multi-functional part 7 or indirectly connected to the drawer rail 6. The multi-functional part 7 forms an end extension of the drawer rail 6 at its front end 2 b directed towards a front 2 b (see FIG. 1) of the drawer 2. This is for the approach especially to the damper 8, the multifunction part 7 or a closing unit 9, e.g. advantageous for their assembly and disassembly, since the drawer guide can be mounted to the body 1 in an exchange remain.

In the longitudinal extension of the multi-function part 7, the closing unit 9 is attached to the drawer rail 6 on the lower side of the latter. The closing unit 9 comprises a sliding element 16 displaceably mounted along the drawer rail 6, at the end remote from the damper 8 a coupler 10 is fastened. When the rails 4, 5, 6 are pushed into one another, the coupler 10 can catch a driver 11 on the rail 4 and, when coupled, move the drawer 2 into its closed position with the aid of e.g. a spring 17 or a tension spring (see Figure 7).

Instead of the damper 8 or the closing unit 9, other components, such as a touch-latch system or a Abdrückeinrichtung can be mounted in a corresponding manner. If these parts have, for example, geometries or dimensions such as the damper 8 or the closing unit 9, the same multifunction part 7 or the same drawer rail 6 can be used or an exchange of the corresponding parts is readily possible.

In Figure 3, the drawer slide 3 is shown in the retracted state with a closing unit 9, but without damper in the multi-function part 7. The driver 11 is caught by the coupler 10 between a stop surface 15 of a recess 12 of the coupler 10 and a stop surface 13a of a resilient tongue 13 in the recess 12 of the coupler 10 (see also Figures 4 and 6). The dimensions are preferably formed so that the driver 11 so between the abutment surfaces 15 and 13 a of the coupler fits, that the resilient tongue 13 is under spring tension and thus the driver 11 resiliently clamped.

In this condition, however, preferably the resilient tongue 13 is still able to continue to spring, i. a possible travel is not yet fully exhausted. This would only be the case when the resilient tongue 13 abuts a surface 14 (see in particular FIGS. 6 and 8).

It is also conceivable that, instead of the abutment surface 15, a resilient surface, e.g. in the form of a spring tongue according to the spring tongue 13 is formed.

In Figures 5 and 6 and Figure 3, the parts of the drawer slide 3 are shown in the closed state. FIG. 5 shows the closing unit 9 with carrier 11. Only the coupler 10 with driver 11 is shown in FIG.

The closing unit 9 comprises a housing 19 and the spring 17 (indicated only by dashed lines), the sliding element 16 and the coupler 10. The spring 17 acts between the rear facing the multifunction part 7 end of the housing 19 and the front end facing the coupler of the sliding element sixteenth The coupler 10 is pivotally mounted via a pin receptacle 18 at the front end of the sliding element 16. The coupler 10 is also provided with a pin 10a formed in it a guideway of the housing 19, not shown, movably guided. In the illustrated state of Figure 5 and 6, the coupler 10 is pivoted in the direction of driver 11 and is seated in the recess 12 of the coupler 10, wherein the resilient tongue 13 is tensioned by the driver 11.

In FIGS. 7 and 8, the extended state for the closing unit 9 is shown. In this state, the driver 11 is removed from the clamping unit 9 or from the coupler 10. The coupler 10 is positioned on a guide head 19a of the housing 19 via an angled portion of the guide track extending therein by means of the peg 10a such that a spring force of the biased spring 17 can be accommodated without the coupler 10 engaging the pusher element 16 Retracts position.

If, when retracting the drawer 2, the carrier 11 is moved towards the coupler 10 with a stop surface 11a (see FIG. 6), the greatest force of the impact from the driver 11 hits the resilient tongue 13, whereby the coupler 10 is swung out via the guide head 19a, such that the spring 17 is capable of retracting the coupler 10 together with the sliding element 16 and the captured carrier 11 into an engaged position according to FIG. The damper 8 ensures in this process that the move into the end position is gentle and not jerky.

However, the resilient tongue 13 also contributes decisively to a generally gentle movement. When the coupler 10 catches the cam 11, the abutment surface 11a of the cam 11 hits the abutment surface 13a of the resilient tongue 13 of the coupler 10 with substantial force. Since the resilient tongue 13 is flexible, it cushions the impact of the cam 11 on the coupler 10 off. As a result, the coupling process is comparatively quiet, resulting in a total smooth and gentle retraction movement of the drawer. 2 is realized. The surface 14 serves the resilient tongue 13 as a travel limit, if the impact would move the resilient tongue 13 beyond the position of the surface 14.

In the figures 9 to 13 variants are shown, as well as the resilient tongue 13 spring members could also be formed. Of course, this is only a selection, a variety of other configurations is also conceivable.

In Figures 9 to 13, not the entire coupler 10 is shown, but only a spring member and the limiting surface 14 for the respective spring member. In all embodiments, a plurality of resilient tongues are arranged in a comb-like manner one behind the other, for example in FIGS. 9, 12 and 13, the resilient tongues 21a, 21b, 21c. In these tongues, the thickness of each tongue changes, wherein a driver initially strikes the thinner and thus softer tongue 21a and, in the course of a coupling movement, optionally the further tongues, which are thicker and thus harder, are deflected. At the end of the tongues, different thickenings 22a, 22b, 22c can be provided, which determine the stop behavior of the respective tongue 21a, 21b, 21c on the respectively adjacent tongue or surface 14. The size of the thickenings may, for example, determine the spring properties in such a way that their expansion, in particular in the longitudinal extent of the tongue, increases, so that the tongue thereby shows rather a stiffer behavior. Even within a tongue 26 (see in particular FIG. 10), elevations or thickenings 23 may be provided, optionally additionally combined with a thickening or elevation 24 at the end of the tongue 26. The delimiting surface 14 may also be wave-shaped, with elevations 25 (FIG. see FIG. 10).

In another embodiment, tongues 27a, 27b, 27c can mutually interlock, in the manner of a zipper (see FIG. 11).

In another embodiment, tongues 21a, 21b, 21c may be formed of a different material than the rest of the coupler as indicated in FIGS. 12 and 13 by a dividing line 28.
