Description

The invention relates to a piece of furniture according to the preamble of claim 1.

State of the art:

Devices for influencing mutually movable furniture parts which realize a drive movement with the aid of spaced-apart gear elements are known from the prior art. For example, for a coordinated movement between a furniture part and guide means coupled to each other rotatable transmission elements are provided.

The European patent application EP 0 129 941 A1 is concerned, for example, with a height adjustment device for a table with at least two legs, wherein a telescopically variable in length rod between worm gear elements is proposed for the height adjustment of the table legs.

Object and advantages of the invention:

Object of the present invention is to provide a piece of furniture with a device for moving a first furniture part relative to a second furniture part with two spaced transmission elements, wherein a common rotational movement of the transmission elements via connecting means between the transmission elements, in which a easy installation of the device should be possible.

This object is achieved by claim 1.

In the dependent claims advantageous embodiments of the subject invention are shown.

The invention is defined in claim 1 and is based on a piece of furniture with a first furniture part, which is movable relative to a second furniture part, in particular with a driven by a drive unit movable drawer, wherein a guide unit for guiding the first furniture part to the second furniture part is, wherein the furniture comprises a device for moving a first furniture part relative to a second furniture part with two spaced-apart transmission elements, wherein for an interconnected rotational movement of the transmission elements connecting means for connecting the transmission elements between them are provided. The essence of the invention is that the connecting means comprise a telescopic connecting shaft. This allows a simple and effective way to achieve an adaptation of the connecting means to different spatial or geometric conditions. In furniture parts, for example, regularly used for different model series or furniture types at least two spaced-apart and coupled gear elements for driving a movable furniture part. In this case, the distances between the gear elements, which are each dimensioned for an arrangement, may be subject to certain fluctuations or may be different depending on the model series. In addition, due to the assembly deviations of the distances between the transmission elements can not be avoided or in most cases. In order to adapt the connecting means to the therefore occurring different distances between the gear elements, is the telescopic Connecting shaft between the gear elements particularly advantageous. The connecting shaft can be made telescopic in different ways. In particular, a stepless or fine-step adjustment of the connecting shaft in the longitudinal direction thereof can thus be realized, for example by means of parts of the invention which can be displaced into one another Connecting shaft.

The connecting shaft can be configured by the telescopic design in their particular outer dimensions transversely to the telescoping almost unchanged compared to non-telescopic connection shafts. As a rule, comparatively small telescopic sections on the connecting shaft are sufficient to overcome the different distances, occurring in practice, of e.g. Approximately +/- 5 mm per longitudinal end of the connecting shaft between the transmission elements to overcome. According to the invention, the connecting shaft comprises a compensating sleeve in order to be able to adapt to a predetermined spacing of the gear elements. A connecting shaft according to the invention is in particular provided with two compensating sleeves, one at each end in the longitudinal direction. With a compensating sleeve, the connecting shaft can be particularly easily changed or length-adjusted in the longitudinal direction. In addition, a compensating sleeve can be made comparatively easy or is also robust. With a compensating sleeve also a subsequent equipment of existing fasteners is readily possible. Hereinafter, the term of the connecting shaft can be understood in particular to mean a longitudinal element to which the compensating sleeve is attached, wherein the compensating sleeve is part of the connecting shaft.

In a further preferred device for moving a first furniture part relative to a second furniture part, in particular in a drawer with touch-latch system, the connecting means are designed such that, for example, in a counter-pressure on a drawer front, on the side at which no Drive unit or a trip unit is present, the force is transmitted via one of the two drawer slides to the rear and further across the connecting shaft transverse to the drive or trip unit, whereby the trigger or drive unit is addressed and the drawer is opened. With the connecting shaft according to the invention can thus be acted from the place of action side or height independently on eg the drive. This can be advantageous, for example, in the case of large drawer fronts if the location of the action is located diagonally away from the drive unit. For this purpose, the connecting shaft is preferably connected to the at least one transmission element, in particular radially or tangentially without play.

It is further proposed that the compensating sleeve is arranged in a region between the connecting shaft part and one of the gear elements. Thus, a distance between the connecting shaft or the connecting shaft part and the transmission element with the compensating sleeve can be overcome. The intermediate layer of the compensating sleeve can also be understood as meaning a partial overlapping or encompassing of the connecting shaft part or of the gear element. By attaching the compensating sleeve in the connecting region between the connecting shaft part and the transmission element also an exact adjustment of the length adjustment of the connecting shaft to the transmission element can be made. In principle, however, a compensating sleeve at another point of the connecting shaft part is also conceivable, for example at a location of the connecting shaft part which is still easily accessible by an operator when the device is installed, for example in a central region along the connecting shaft part. If the compensating sleeve is provided in the connection region between the connecting shaft part and the transmission element, a certain increase in the binding stability between the two may possibly occur with the compensating sleeve be realized both parts to be joined.

It is particularly preferred if the compensating sleeve can be attached to the connecting shaft part. Thus, in particular without tools or with a few simple steps, the compensating sleeve attached to the connecting shaft part or optionally removed again. In particular, the compensating sleeve can be provided with a receptacle, with which a portion of the connecting shaft part can enter into a connection. For example, the compensating sleeve may be provided with corresponding contours, which are matched to counter contours on the connecting shaft part. Here, for example, inner and outer teeth profiles are conceivable.

In an advantageous embodiment of the device according to the invention, the compensating sleeve can be attached to a transmission element. In principle, the aforementioned advantages can thus be achieved. The compensating sleeve is designed as a separate component. This makes it particularly effective to realize the adaptation of the connecting shaft to different distances between the gear elements. In addition, the connecting shaft part may optionally be made of a different material than the connecting sleeve as a further separate component. Advantageously, it can be easily retrofitted with connecting means used. It is only necessary to adapt a compensating sleeve to the existing connecting means or to respective sections of the connecting shaft part. It is particularly preferred in this case that the compensating sleeve is detachably attachable or attachable to both the connecting shaft part and to the transmission element. In addition, a separate compensating sleeve can be designed in accordance with their length so that the respectively to be overcome balance distance between the Connecting shaft part and the transmission element is bridged in an ideal manner.

In a preferred embodiment of the device according to the invention, the compensating sleeve can be arranged in at least one mounting position on the connecting shaft part, in particular in one of a plurality of possible attachment positions in the longitudinal direction of the connecting shaft part. Thus, the compensating sleeve can be comparatively easily adapted to different distances to be overcome between the connecting shaft part and the gear elements. For example, with a standardized compensating sleeve most of the adjustments occurring in practice of the connecting shaft can be made to different distances between the transmission elements.

It is particularly preferred if the compensating sleeve is movable in the longitudinal direction displaceably on the connecting shaft part. Thus, the compensating sleeve is guided on the one hand movable and can also be continuously or finely positioned along the connecting shaft part and fixed thereto in the selected position. In this way, a particularly accurate compensation or precise adjustment of the connecting shaft relative to the transmission element can take place. Furthermore, a correction of the mounting position of the compensating sleeve on the connecting shaft part can be easily made, for example, to compensate for installation and operating tolerances, which influence the distance of the transmission elements. For example, by different wall thicknesses of furniture parts such as press plates can justify such an installation tolerance. In addition, the sliding arrangement of the compensating sleeve on the connecting shaft part ensures particularly good guidance and holding of the compensating sleeve on the connecting shaft part.

In a further preferred embodiment of the subject invention, the compensating sleeve is releasably fixed in each case in one of a plurality of mounting positions on the connecting shaft part. Thus, the compensating sleeve can always be brought into its exact desired position and fixed there, e.g. by hand. The compensating sleeve can in particular be fastened with self-locking means to the connecting shaft part. If an adjustment or removal of the connecting shaft or the transmission element are necessary, the fixed fixation can be solved at any time. In addition, a readjustment for the length adjustment of the connecting shaft can be realized.

For the releasable fixing or fixing of the compensating sleeve on the connecting shaft part, a multiplicity of possible mechanisms and configurations are conceivable. For example, in an over the connecting shaft portion circumferentially pushed over compensating sleeve a bore with internal thread can be provided, in which a fixing screw can be screwed, whereby the fixing screw for firm fixation of the compensating sleeve on the connecting shaft part presses firmly against this. By loosening or loosening the fixing screw, the compensating sleeve can be released again from its fixed position on the connecting shaft part. Optionally, corresponding contours for the engagement of the fixing screw for their better engagement in the connecting shaft part can be provided in defined positions on the connecting shaft part. An alternative solution can be done by various Einklemmmechanismen. For example, a spring element arranged on the outside of the compensating sleeve can reach through its ends via two openings in the compensating sleeve into a corresponding depression or groove on the outside of the connecting shaft part. The at the balance sleeve clipped or clamped spring element thus holds the compensating sleeve on the connecting shaft part by clamping.

Basically, with two each arranged at one end of the connecting shaft part shims one fixed fixed to the connecting shaft part and the other movable attack it

For fixing the compensating sleeve to the connecting shaft part, for example, a push-through pin can be provided which engages through a hole in the compensating sleeve and engages in a receiving portion in the connecting shaft part, whereby a change in the position of the compensating sleeve relative to the connecting shaft part is not possible.

It is particularly preferred if the compensating sleeve can be connected to the connecting shaft part and the transmission element. Thus, the balancing sleeve, so to speak, an adapter piece between the connecting shaft part and the transmission element. Thus, a particularly compact or stable connection and adaptation of the connecting shaft to the transmission element can be realized. Advantageously, the compensating sleeve may be formed as a sleeve part in which engages the connecting shaft part at one end in a recess and at the other end in a further recess engages a portion of the transmission element. For a rotation of the balance sleeve on the connecting shaft part or the transmission element can each be provided a corresponding Eingreifkontur between the transmission element and the recess in the balance sleeve or between the recess of the balance sleeve and the inserted therein part of the connecting shaft part. For example, a multiple toothing can be set up as plug-in or anti-twist device.

Finally, it is further proposed that the compensating sleeve comprises an attachable to the connecting shaft part and / or the transmission element sleeve part. A sleeve part is particularly compact and stable ausbildbar. In addition, can be easily realized with a sleeve part an aligned orientation or a guided displacement on a counter element. Also, a certain protective function in the connection region between the connecting shaft section and the transmission element can be realized on the overlapped sections by an over-pushed sleeve element. Moreover, it is advantageous that a sleeve part advantageously be guided both displaceable relative to the connecting shaft part and a portion of the transmission element, in particular in an aligned opening.

FIG. 6

a highly schematic representation of a furniture according to the invention in partial view.

FIG. 1 shows a connecting shaft part 1, which may be formed for example on essential sections as a square profile made of steel. The connecting shaft part 1 serves for the coupled connection between rotatably movable toothed wheels 2 and 3. The toothed wheels 2 and 3 are each held in a holding element 4 and 5. On the holding element 4, for example, a drive unit 6 is mounted, which serves for the rotary drive of the gear 2. The connecting shaft part 1 is designed to be telescopic. This is realized by two compensation sleeves 7 and 8.

In the FIG. 1 shown arrangement, for example, in the area between two wall portions of a furniture body part (not shown) are housed by, for example, the holding elements 4, 5 on the furniture body are attached. In order to overcome occurring in practice different distances a between the two gears 2 and 3, the compensating sleeves 7, 8 are slidably attached to the connecting shaft part 1. This is especially true in the Figures 3 and 4 better visible. The connecting shaft comprises the connecting shaft part 1 and the compensation sleeves 7 and 8.

The compensation sleeves 7, 8 are configured for example as cylindrical hollow sleeves. The compensating sleeve 8 is shaped in principle according to the compensating sleeve 7. The compensating sleeve 8 is provided with a passage opening 8b which has an internal tooth profile 8a with which an external tooth profile 1a of the connecting shaft part 1 can form a toothing, by inserting the corresponding end section of the connecting shaft part 1 into the passage opening 8b of the compensating sleeve 8 FIG. 4 is plugged in. At the other end of the compensating sleeve 8 in the longitudinal direction, a further inner tooth profile 8c is formed in the passage opening 8b located there with a larger diameter. The inner tooth profile 8c of the compensating sleeve 8 forms a toothing with a correspondingly designed external tooth profile 3a of a journal section 3b of the toothed wheel 3. The compensating sleeve 8 is thus longitudinally displaceable relative to the connecting shaft part 1 or the external tooth profile 3a on the journal section 3b, as shown by the arrow P1. In this way, a length compensation can be realized on the connecting shaft or the connecting shaft part 1 in order to be able to compensate, in particular, for different distances between an end face 1b of the connecting shaft part 1 and an end face 3c of the pivot section 3b. Overall, therefore, the connecting shaft part 1 can be configured together with the compensating sleeves 7, 8 as a telescopic connecting means or connecting shaft.

Not shown in the figures is a fixing device for releasably fixing the compensation sleeves 7, 8 relative to the connecting shaft part. 1

FIG. 5 shows obliquely from above an inventive piece of furniture 9, which comprises a body 10 and a movable therein drawer 11. The arranged in the lower region of the body 10 drawer 11 is shown in the open or pulled out state, wherein the mutually movable furniture parts 10, 11 via a pull-out or a drawer slide 12 are mutually displaceable. In the body 10, a further drawer, not shown, can be accommodated in the same way via a further drawer slide 12a. The drawer 11 can be pulled out or pushed in relative to the body 10 in accordance with the double arrow P2. For holding or guiding the movement of the drawer 11 is in the lower region of both sides of a drawer bottom 11c upwardly projecting drawer frames 11a each a similar drawer slide 12 housed, wherein in FIG. 5 only on a body inside the drawer slide 12 and 12a can be seen. The drawer 12 can be driven, wherein the drive unit can be arranged for example in the rear region of the body and / or the guide 12 (not shown here).

In FIG. 6 is highly schematized in section and in plan view a drawer 13 in a body only partially shown with side walls 14, 15 shown. The drawer 13 is driven via a left guide 16 and right guide 17 driven by a drive 18. Transmission elements 19, 20 are connected via a connecting shaft 21 according to the invention. The connecting shaft 21 and the gear elements 19, 20 are inventively designed such that when acting at the point A of a drawer front 13a of the drawer 13 by pressure, on the guide 16, the transmission element 20, the Connecting shaft 21 and the transmission element 21 can be acted upon the drive 18 so that this example initiates the opening movement of the drawer 13.
