Description

Fastening device for a furniture part

The invention relates to a device for attaching a functional unit to a rail of a drawer extension guide. Furthermore, the invention relates to a drawer pull-out guide and a piece of furniture with such a device. Furthermore, the invention relates to a set of at least two functional units.

Such devices are already known in a variety of the prior art.

The object of the invention is to provide an improved device for attaching a functional unit to a rail of a drawer extension. This is achieved according to the invention by the features of patent claim 1.

According to the invention, it is thus provided that the device has at least one coupling element by which at least two different functional units can optionally be fastened to the drawer extension guide.

This makes it possible that two different functional units can be attached via the same device. This causes that not different devices for the attachment of functional units are needed, but this can be done with a single device. This helps to reduce both the costs in the production as well as that - should a functional unit be replaced once - not the device must be replaced but the existing device can be used to accommodate the new functional unit. Further advantageous embodiments of the invention are defined in the dependent claims.

To be particularly advantageous, it has been found that the functional units releasably - preferably without tools - are fastened to the coupling element. The fact that the functional units are detachably fastened, they can be retrofitted attached or subsequently dismantled and can therefore be easily replaced. It is particularly advantageous if this can be done without tools, since this helps to keep the assembly time short.

According to a preferred embodiment it can be provided that the coupling element has a latching device. By means of a locking device can be achieved that no additional installation activities for attaching a functional unit to the drawer extension guide are necessary.

Furthermore, it can preferably be provided that at least one coupling element is formed on the carcass rail and at least one further coupling element is formed on the drawer rail. By a further coupling element on the drawer rail, a functional unit disposed thereon can be moved with the drawer rail, while the coupling element can serve as a control for the functional unit on the cabinet rail, such as on / off switch for the functional unit, as a damping part for a retracting furniture part or Also as a stop member from which can repel a designed as a furniture drive functional unit. As advantageous, it has further been found that the functional units can be fastened by the device to the drawer rail of the drawer extension guide. It can thereby be achieved that the functional units move with the drawer rail of the drawer pull-out guide when the drawer is moved out or retracted.

It has proven to be particularly advantageous if the coupling element is designed hackenförmig. A hook-shaped design allows rapid attachment of a functional unit to the drawer extension guide via the coupling element of the device.

Particularly preferably, it can be provided that the device is designed as a unit independent of the drawer extension guide. An embodiment of the device as an independent structural unit makes it possible to subsequently attach the device to a drawer extension guide or to a functional unit and thus make it possible for the device to be subsequently attached to a drawer pull-out guide Drawer pull-out guide or a functional unit can be attached. Thus, it is possible to perform a subsequent assembly in an existing Schubladenausziehführungssystem, the drawer pull-out does not need to be replaced.

It has proven to be particularly advantageous if the device is at least partially formed on the underside of the drawer rail and / or at least partially on the side remote from the body of a piece of furniture of the drawer rail. By means of an embodiment on the underside of the drawer rail and / or on the side of the drawer rail facing away from the body, it is possible to achieve that the existing free space underneath a drawer can be used for the device.

According to a preferred embodiment it can be provided that the functional units are arranged by the device laterally, substantially parallel to the drawer rail, on the side of the drawer extension guide facing away from a furniture carcass. By such a configuration can again be achieved that the free space can be used under a drawer for the device.

It has also proved to be advantageous that the functional unit has an ejection device for ejecting a rail of the drawer extension guide from a closed end position into an open position. Furthermore, it has been found to be advantageous if the functional unit has a feed device through which a rail of the drawer pull-out guide towards the end of the closing movement can be pulled into the full closed position and / or that the functional unit has a damping device for damping a rail movement of the drawer pull-out.

Preferably, it can further be provided that the functional units are supported on the coupling element of the device. By supporting it can be contributed to a quick installation can be done. It is also proposed that the coupling element of the functional unit is designed to be movable, preferably spring-loaded.

It has proven to be advantageous if, in the case of relative movement of the rails relative to one another, the coupling element of the functional unit temporarily couples with the coupling element of the rail and / or rests temporarily on the coupling element of the rail.

A particularly advantageous structural variant provides that the functional unit is releasably secured by the device to the drawer rail of the drawer extension and moves together with the drawer rail, wherein the coupling element of the functional unit also moves together with the drawer rail and the coupling element corresponding to the coupling element of the functional unit relative is unmoved to the functional unit.

The reverse variant can also be provided if the functional unit is detachably fastened by the device to the carcass rail of the drawer extension guide and the coupling element corresponding to the coupling element of the functional unit moves together with the drawer rail.

It has proven to be particularly advantageous if at least two functional units can be fastened to the device at the same time and / or that at least two functional units can optionally be fastened to the device.

Protection is also desired for a drawer pull-out guide with a cabinet rail to be fastened to a furniture body and at least one drawer rail displaceably mounted relative to the cabinet rail, at least one functional unit being connected to the cabinet rail or drawer rail via a device according to one of claims 1 to 12.

Specifically, protection is desired for a piece of furniture with at least one drawer extension guide with a device according to one of claims 1 to 12. S

FIG. 1a shows a symbolic representation of a drawer pull-out guide 2, wherein the drawer pull-out guide 2 has two rails 21 and 23, the rail 23 representing a cabinet rail and the rail 21 a loading rail. On the drawer rail 21, a coupling element 7 of a device 1 for attachment of functional units 3, 4 and 5 is arranged.

The functional units 3, 4 and 5 also have a coupling element 8, via which the functional units 3, 4 and 5 can be selectively attached to the coupling element 7 of the drawer rail 21. It is thereby achieved that one and the same drawer pull-out guide 2 can accommodate different functional units 3, 4 or 5 on the drawer pull-out guide 2.

Furthermore, the carcass rail 23 has a coupling element 6, with which the functional units 3, 4 and 5 correspond via the coupling elements 6 'to the coupling element 6 of the carcass rail 23.

In this preferred embodiment, the drawer pull-out guide system 2 has a coupling element 7 on the drawer rail 21, via which the functional units 3, 4 and 5 move with the drawer rail 21 On the other hand, the drawer pull-out guide 2 has on its carcass rail 23 a coupling element 6 which does not move together with the functional units 3, 4 and 5 or the drawer rail 21. Figure 1b shows a schematic representation of a functional unit 3, which is designed as an ejection device. About the coupling elements 8, this functional unit 3 is detachably fastened to a bar Drawer pull-out guide 2, not shown here. The coupling element 6 'corresponds to the coupling element 6, wherein the functional unit 3 is detachably secured by the device 1 to the drawer rail 21 of the drawer extension guide 2, not shown here, and moves together with the drawer rail 21, wherein the coupling element 6' of the functional unit 3 also together moves with the drawer rail 21 and with the coupling element 6 'of the functional unit 3 corresponding coupling element 6 is relatively unmoved relative to the functional unit 3.

If now the functional unit 3 is moved in the direction of the coupling element 6, then the coupling element 6 moves in the trained as a heart curve guide in the functional unit 3 until it reaches its resting point - the coupling element 6 ', which is formed as a recess in the heart curve. In this case, the functional unit 3 and thus also the coupling element 6 'of the functional unit 3 was pretensioned via the spring device 30. If we again exert pressure on the functional unit 3, then the coupling element 6 moves out of the logging in of the heart curve of the functional unit 3 and the functional unit 3 and together with it the drawer rail 21 not shown here are ejected. It could, of course, also be the other way around, that the device 1 is releasably connected to the carcass rail 23 of the drawer extension guide 2, which is not shown here, and the coupling element 6 corresponding to the coupling element 6 'of the functional unit 3 moves together with the drawer rail 21. Of course, this principle also applies to the functional unit 4 shown in FIG. 1c as a damping device as well as to the functional unit 5 shown in FIG. 1d as a collection device. Figure 1c shows the functional unit 4, which is formed in this embodiment as a damping device and a coupling element 6 ', which rests temporarily on the coupling element 6, when the drawer, not shown here, at which the functional unit 4 is located on the Schienenausziehführung 2, not shown , is inserted into the furniture carcass. When the coupling element 6 'of the functional unit 4 strikes the coupling element 6, the functional unit 4 and thus also the drawer rail 21 with which the functional unit 4 is connected via the coupling elements 8 are braked. Figure 1d shows a functional unit 5 which is designed as a collection device. At the moment where the movable spring-loaded coupling element 6 'of the functional unit 5 strikes the coupling element 6, the functional unit 5 and the drawer rail connected thereto are retracted via the spring device 30.

For all three functional units 3, 4 and 5, as shown in FIGS. 1b, 1c and 1d, it is thus true that with a relative movement of the rails 21, 22 and 23, not shown here, the coupling element 6 'of the functional units 3, 4 and 5 temporarily coupled with the coupling element 6 and the rails 21, 22 and 23 and / or temporarily applied to the coupling element 6 of the rail 21, 22 or 23. Likewise, it is of course conceivable that the coupling element 6 is formed in a furniture body, not shown here, and not on one of the rails 21, 22 or 23.

FIG. 2 shows a perspective view of a drawer pull-out guide 2 and three functional units 3, 4, and 5 attachable to it. These different functional units 3, 4 and 5 can optionally be fastened to the drawer slide 21 of the drawer pull-out guide 2 via the coupling elements 7 of the device 1. Furthermore, in this preferred embodiment, the functional units 3 and 5 can also be attached to the drawer rail 21 of the drawer pull-out guide 2 at the same time. The functional units 3, 4 and 5 are preferably attachable without tools to the coupling elements 7. Furthermore, in this preferred exemplary embodiment, the drawer pull-out guide 2 has on its carcass rail 23 the coupling element 6 of the device 1. At this coupling element 6, the functional units 3, 4 and 5 are also attached. However, this attachment is only temporary in this preferred embodiment, that is, when the drawer rail is extended, the functional unit has no contact with the coupling element 6. The coupling element 6 of the carcass rail 23 is designed such that it extends below the middle rail 22 and the drawer rail 21 and can engage in a guide groove of the functional units 3, 4 and 5. This is preferably used to the fact that, for example, the functional unit 3 can repel this coupling element 6 and thus a drawer, not shown, can be ejected from the furniture, not shown.

On the other hand, the coupling element 6 can be used to cause a damping device, not shown, in one of the functional units, an attenuation of the drawer on the coupling element 6. Likewise, of course, the coupling element 6 can be used for automatic retraction of the functional units. Furthermore, of course, a variety of other functions are conceivable, which can be controlled via the coupling element 6.

The coupling element 6 is hook-shaped, whereby the functional units 3, 4 and 5 can be supported on the coupling element 6 of the device 1. The functional units 3, 4 and 5 in this preferred exemplary embodiment belong to a set 200, wherein the functional units 3, 4 and 5 can be fastened optionally via the device 1 for attaching one of the functional units 3, 4 or 5 to a rail 21 of the drawer pull-out guide 2. Likewise, it is of course conceivable that the functional units 3, 4 or 5 could not be attached to the drawer rail 21 but to the middle rail 22 or to the carcass rail 23 via a device 1. In this preferred embodiment, the device 1 is at least partially formed below the drawer rail 21 and further partially formed on the side facing away from the body 101 of a furniture 100, not shown side of the drawer rail 21. This makes it possible for the functional units 3, 4 and 5 to be arranged laterally, essentially parallel to the drawer rail 21, on the side of the drawer pull-out guide 2 facing away from the furniture body 101 by the device 1. In a particularly preferred embodiment, the device 1 is formed as an independent structural unit of the drawer pull-out guide 2. This makes it possible, for example, that the device 1 can subsequently be distributed to an already existing drawer extension guide 2 as a retrofit kit. As functions for the functional units 3, 4 and 5 various embodiments are conceivable, such as that the functional units has an ejection device for ejecting one of the rails of the drawer extension guide 2 from a closed end position to an open position or about that the functional units have a collection device through which a rail of the drawer extension guide 2 against the end of the closed position in the full closed position can be pulled and / or that the functional units have a damping device for damping a rail movement of the drawer extension guide 2. It is also conceivable that the functional units have a synchronizing device 41, as is the case for example with the functional units 4 and 5 in this exemplary embodiment.

3 shows a perspective view of a drawer pull-out guide 2 with a drawer rail 21, a middle rail 22 and a carcass rail 23. On the carcass rail 23, a hook-shaped coupling element 6 of the device 1 for receiving the functional units 3, 4 and 5, not shown here. FIG. 4 a shows a representation of a drawer pull-out guide 2, as shown in FIG. 3, in a perspective bottom view. Both in the figure 4a as well as in a detailed view of Figure 4a - Figure 4b - further coupling elements 7 are shown, which also serve for receiving and positioning of the functional units 3, 4 and 5, not shown here.

5a shows a perspective view of a functional unit 4. FIG. 5b shows a bottom view of the functional unit 4 shown in FIG. 5a. In this case, the coupling element 6 'can be seen, which is connected to a coupling element not shown here

Via the coupling elements 6 and 6 'of the device 1 for attaching a functional unit to a rail of the drawer pull-out guide 2, the functional unit 4 is releasably attached to the carcass rail 23 of the drawer pull-out guide 2 attached.

FIG. 8a shows a further functional unit 4 'in perspective view. In this exemplary embodiment, the functional unit 4 'has a synchronization device 41 for synchronizing a drawer extension guide with a further drawer extension guide. On the underside-as shown in FIG. 8b-this functional unit 4 'also has a coupling element 6' as well as coupling elements 8 of a device 1 by means of which the functional unit 4 'can be fastened to a rail of a drawer extension guide 2, not shown. FIG. 9 shows a perspective view of the functional unit 4 'shown in FIGS. 8a and 8b, as shown on a drawer pull-out guide 2-taken exactly on its drawer rail 21 and its cabinet rail 23-via the device 1 and its coupling elements 6, 6', not shown here. , 7 and 8 is connected.

FIG. 10a and FIG. 10b show a bottom view of the arrangement shown in FIG. 9 of a drawer pull-out guide 2 and functional unit 4 'arranged thereon.

In the detailed view of Figure 10b, the two coupling elements 6 and 6 'can be seen, which correspond to each other.

FIG. 1 shows a perspective view of an extended drawer pull-out guide 2. The functional unit 3 is fastened to the drawer rail 21 via the device 1 (by means of the coupling elements 7 and 8, not shown here).

The carcass rail 23 has the coupling element 6, which comes into contact with the functional unit 3 when the drawer rail 21 retracts. This functional unit 3 uses the coupling element 6 in order to repel it and thus eject a drawer, not shown here, from the furniture. When retracting drawer, the coupling element 6 is used as part of a damping device of the functional unit 3. The coupling element 6 is hook-shaped and can penetrate under the drawer rail 21 into a groove of the functional unit 3 and thus correspond with it.

The device 1 thus has in this preferred embodiment, on the one hand coupling elements 7 and 8, which moved together with a drawer rail 21 and further, it has a coupling element 6 which does not move together with the drawer rail 21, but is fixed to the carcass rail 23.

FIG. 12a clearly shows how the coupling element 6 extends from the body rail 23 below the drawer rail 21 (see detailed illustration of FIG. 12b). FIG. 13 shows a piece of furniture 100 with a furniture body 101. Two drawer pull-out guides 2 are arranged on the furniture body 101, the drawer pull-out guides 2 each having a drawer rail 21 as well as a cabinet rail 23.

At the drawer extension guide 2 are each not shown here devices 1 for attachment of functional units 3, 4 or 5, not shown here on the drawer rail 21 of the drawer extension guide 2 is formed.
