With regard to precautions and/or the modalities in connection with the assembly of such devices, a comparatively high level of effort has so far been expended.

The state of the art AT 508 265 A1 and the DE 10 2010 000 513 A1 called.

Object and advantages of the invention

The object of the present invention is to improve the above-described problems or the existing systems mentioned or to enable a more effective procedure.

This object is solved by the independent claims.

The dependent claims relate to advantageous variants of the invention.

The invention is initially based on a device for attaching a guide unit to a first furniture part, which can be movably guided with the mounted guide unit in relation to a second furniture part, the guide unit comprising a fixed rail which can be arranged on the second furniture part and a movement rail which can be arranged on the first furniture part, the device being designed for a movement rail which is equipped at the rear end with hooking means for fixing the first furniture part, the hooking means being designed, in a mounted state on the first furniture part, in a receiving device which can be assigned to the furniture part device to intervene. The first furniture part is held or fixed in the rear area of the first furniture part or on the end area of the furniture part opposite a front side of the furniture part in its longitudinal direction.

A first essential aspect is that the receiving device is designed for coupling to the hook means on the guide unit before the guide unit is attached to the first furniture part for the first time in such a way that when the guide unit is attached together with the coupled receiving device, an automatic connection can be set up between the receiving device and the first furniture part when contact is made between the first furniture part and the receiving device and prepared thereon. The automatically establishing connection, which in particular fixes the receiving device in a fixed position on the first furniture part, is preferably established permanently or can only be reversed or canceled again by overcoming a predeterminable acting force.

Advantageously, the receiving device can be transferred from a state releasably assigned to the guide unit, which exists before the first furniture part is mounted on the guide unit for the first time, to a state permanently or possibly non-releasably assigned to the first furniture part after assembly.

The establishment of the connection between the receiving device and the first furniture part is in particular not reversible with an initial contacting of mutually associated sections on the receiving device and the first furniture part. The attachment means are advantageously present either only on the first furniture part or only on the receiving device or both on the first furniture part and on the receiving device. The attachment means are preferably present over the complete extent of the mutually associated sections on the receiving device and/or the first furniture part. It can also be advantageous for the attachment means to only partially extend over the sections assigned to one another.

The sections assigned to one another can be designed in the same way on the first furniture part and on the receiving device, or differently with components that are coordinated with one another to form a fixed connection that is effective when combined.

The receiving device is preferably designed as a separate component, in particular as exactly one component or as a structural unit.

The hook means are advantageously designed integrally on the guide unit or the movement rail, or alternatively attached thereto in a fixed or detachable manner. Advantageously, the hook means comprise, for example, a hook element with a hook nose, for example with hook sections standing at an angle to one another, in particular with a first hook section which is perpendicular to a support side of the movement rail for supporting the first furniture part in its position protrudes properly attached condition, and a second hook portion, which includes the hook nose and is angled to the first hook portion, in particular extends towards the support side of the movement rail.

When the guide unit is in the attached state on the first furniture part, the hook nose can engage in a depression or opening of the receiving device that matches the hook nose. Thus, the first furniture part and the guide unit are functionally connected to one another or suitably aligned with one another.

The procedure according to the invention is also advantageous because it is not possible for the receiving device to be installed in the wrong position on the first furniture part, which has repeatedly happened in the past, for example due to manufacturing tolerances. Attaching the receiving device to the guide unit prevents later incorrect assembly on the first furniture part, since the correct assembly position of the receiving device on the first furniture part is automatically set when the guide unit and the first furniture part are brought together in the correct position.

It is also advantageous that the connection means are designed in such a way that the automatic connection between the receiving device and the first furniture part can be set up when the guide unit and the first furniture part are correctly positioned. This advantageously ensures that the automatic connection between the receiving device and the first furniture part takes place only when the relevant parts are correctly positioned relative to one another and vice versa is not possible or the two parts remain unconnected. In any case, a fitter carrying out the assembly receives immediate feedback about successful attachment if the receiving device remains on the first furniture part as desired, if the first furniture part is removed again from the guide unit for testing, for example, or otherwise remains coupled to the hook means.

It is also according to the invention that the attachment means comprise adhesives. This is a particularly advantageous and simple connection option. An adhesive surface can advantageously be prepared on the first furniture part and/or on the receiving device. An adhesive surface can be covered or protected by a removable, in particular thin, protective film until the protective film is removed by a fitter before the guide unit is attached to the first furniture part. Alternatively, a connection can also be made via a combination of hook tape on the one hand and an eyelet tape that hooks onto the hook tape when it is in contact on the other hand, in particular to form a detachable Velcro connection that can be set up again several times.

It is also according to the invention that the receiving device has contact sections designed to match the first furniture part, which can be brought into contact with mating sections in the rear region of the first furniture part when there is a correct positional alignment between the guide unit and the first furniture part. In this way, a space-saving connection between the receiving device and the first furniture part, which acts via associated surfaces, can take place.

In particular, the shape of the mutually associated sections on the first furniture part and the receiving device can advantageously be coordinated in such a way that the automatic connection can be set up in particular without the risk of tilting. The mutually assigned sections are formed with a precise fit, in particular with exactly one shoulder with flat sections aligned at an angle to one another, so that there are preferably at least two continuous flat contact areas on each of the mutually allocated sections on the first furniture part on the one hand and the receiving device on the other hand, which are preferably matched to one another according to a form fit.

It is also advantageous that the receiving device has a recess designed to match the guide unit, which is designed for the hook means of the movement rail to engage when there is a correct position alignment between the guide unit and the first furniture part. This allows a precise and correctly positioned attachment to be achieved. Advantageously, no recess or opening has to be prepared on the first furniture part itself for engaging the hook means in the correctly positioned attachment state.

It is also advantageous that the recess and the hooking means are matched to one another in such a way that when the receiving device is coupled to the guide unit, a holding force holding the hooking means in the recess is lower than a connecting force established between the receiving device and the first furniture part via the connecting means. Thus, when the first furniture part is removed from the guide unit, the first furniture part together with the receiving device can be detached from the hook means and then reconnected to the guide unit in the correct position. The forces which in the connected state of the first furniture part, the hooking means can be detachably held in the recess, can be realized, for example, by resilient or elastically behaving clamping sections on the recess and/or the hooking means.

The receiving device advantageously comprises an adjusting device with a receiving element, in which the hook means engage when the guide unit is attached to the first furniture part, the receiving element being adjustable on the adjusting device in at least one spatial direction. Advantageously, the receiving element on the adjustment device can be adjusted in the horizontal and vertical direction, for example manually or without tools. If necessary, a corresponding spatial positioning or fine adjustment of the first furniture part relative to the guide unit and thus to the second furniture part or to a furniture body can be set up.

In this way, for example, a front image of the first furniture part can be adjusted relative to the second furniture part, in particular in order to obtain a uniform joint image between the front furniture part edges of the first furniture part and other elements of the furniture in question.

The invention also relates to a guide unit for a first furniture part, which can be movably guided relative to a second furniture part of a piece of furniture via the mounted guide unit, the guide unit comprising a fixed rail that can be arranged on the second furniture part and a movement rail that can be arranged on the first furniture part, which is equipped at the rear end with hook means for fixing the first furniture part, the hook means being designed to engage in a mounted state on the first furniture part in a receiving device of the device that can be assigned to the first furniture part. According to the invention, the guide unit has a device for attaching a guide unit to a first furniture part according to one of the embodiments explained above.

The advantages mentioned can thus be achieved with the guide unit.

In addition, the invention relates to a piece of furniture with a first furniture part that can be movably guided relative to a second furniture part of the piece of furniture via a mounted guide unit, with a guide unit according to the aforementioned embodiment being present. The piece of furniture comprises, in particular, at least one drawer which is movably guided on a furniture body with a rail guide designed as a full or partial extension.

Furthermore, the invention extends to a method for attaching a first furniture part to a guide unit which is attached to a second furniture part in order to guide the first furniture part in a movable manner relative to the second furniture part, the guide unit comprising a fixed rail which can be arranged on the second furniture part and a movement rail which can be arranged on the first furniture part, the movement rail being equipped at the rear end with hooking means for fixing the first furniture part and the hooking means being designed in a mounted state on the first furniture part in a receiving device which can be assigned to the first furniture part intervene on the device.

The essential idea of the method according to the invention is that the receiving device for a coupling with the hook means is releasably attached to the guide unit before the guide unit is attached to the first furniture part for the first time, with the attachment of the guide unit together with the coupled receiving device via connection means acting between the furniture part and the receiving device and being prepared thereon, an automatic connection between the receiving device and the first furniture part is set up when they are first contacted.

In this way, preparatory measures for mounting the guide unit on the first furniture part can advantageously be carried out and the mounting itself can be carried out effectively. In particular, the advantages shown in connection with the device according to the invention for attaching a guide unit to a first furniture part can be achieved.

The drawer 1 is shown in the rear end area of a drawer back side 2 or drawer rear wall is detachably attached to a drawer rail 3 of the guide unit. The drawer rail 3, which preferably comprises a sheet metal profile bent several times, is part of the guide unit according to the invention, which has rails that can be telescoped or slid relative to one another, in particular next to the drawer rail, which can be assigned to the drawer, a body rail that can be assigned to the body and, if necessary, a middle rail that acts between the body rail and the drawer rail 3. The cabinet rail and the center rail are in 1 not shown.

In the rear end section 4 of the drawer rail 3 there are hook means designed as a hook element 5 on a support side 3a of the drawer rail 3 . The hook element 5 is advantageously configured as a tongue-like element that is cut free from the flat material of the support side 3a of the drawer rail 3 via a U-shaped cut, except for a connecting section, which is bent upwards at a right angle in the remaining connecting section to the support side 3a and forms a section 5a. In addition to the section 5a, the hook element 5 has a further section 5b which is bent over at a right angle to the section 5a.

The section 5b forms a free end of the hook means and runs horizontally or preferably parallel to the support side 3a when the drawer rail 3 is in the mounted, aligned state.

Between the back of the drawer 2 and the hook element 5 there is a receiving device 6, which is advantageously designed as an adjustment adapter, in the correct position. The receiving device 6 comprises a receiving area with a shoulder for contact with angled counter-sections of the drawer 1.

The shoulder of the receiving device 6 is formed by a support section 6a with a support surface 10 facing the underside 7 of the drawer and a wall section 6b with a wall surface 11 facing the inside of the drawer back 2. The support surface 10 and the wall surface 11 are at right angles to one another. The support section 6a has an underside 12 that is preferably aligned parallel to the support surface 10 and which, when the drawer 1 and guide unit or drawer rail 3 are in the assembled state, lies loosely flat on the support side 3a of the drawer rail.

The receiving device 6 has a recess 6c matched to the section 5b, the recess being matched in particular with regard to its holding function for the hook element 5, the position on the receiving device 6 and the dimensions of the section 5b. In the functionally correct assembly state, the section 5b engages in the recess 6c in a lightly resting and/or clamped manner. The drawer 1 can from the according 1 shown attached or held position on the drawer rail 3 with comparatively moderate forces that can easily be applied by a person from the drawer rail 3 or unthreaded by the drawer 1 with the receiving device 6 is pulled forward in direction P1, if necessary with a slight tilting movement of the drawer upwards.

The connection means 8 are designed here, for example, in the form of an adhesive layer 9, the thickness of which is a in 1 is not shown to scale but enlarged. The connection means 8 can be prepared before the connection of the drawer rail 3 and the drawer 1 on the receiving device 6 and/or the back of the drawer 2 .

The adhesive layer 9 is advantageously present over the entire surface or closed over almost the entire vertical height of the side of the rear section 6b of the receiving device 6 facing the rear of the drawer 2 between the rear section 6b and the correspondingly opposite section of the rear of the drawer 2 .

The receiving device 6 is generally matched to the drawer rail 3 and the drawer 1 in such a way that when the drawer 1 is in the correct position on the drawer rail 3 according to FIG 1 On the one hand opposite surfaces of the recording device 6 or the back section 6b, i.e. here the wall area 11, and the drawer 1, i.e. here the drawer back 2, are aligned in parallel and on the other hand opposite outside pages or surfaces of the edition section 6a, i.e. here the contact surface 10, parallel is also aligned with the underside 7 of the drawer section 6a, which also shows an underside. to the support page 3a of the drawer rail 3 in the assembly state runs in parallel. The connection means 8 or the adhesive layer 9 are thus advantageously formed over the entire areal extent with a layer thickness a that remains the same.

If there is any deviation from the parallelism of the surfaces under consideration, which can never be ruled out in practice or may even be deliberate, the layer thickness of the adhesive layer 9 can compensate for this to a small extent due to a certain flexibility or toughness of the adhesive material. more beneficial way, the binding function of the adhesive layer is retained.

When the guide unit is first installed on the drawer 1 according to the invention, the receiving device 6 is present on the drawer rail 3 via the section 5b held in the recess 6c and fixed in the correct position.
