Technical Field
The invention relates to a furniture fitting for connecting two furniture parts having the features of the preamble of claim 1, and to a piece of furniture having at least two furniture parts which are connected to one another by means of at least one furniture fitting.
Background
Such a furniture fitting for connecting two furniture parts is known from EP0698357B 1. The furniture fitting described therein has an expansion screw for fastening the furniture fitting to one of the furniture parts. Furthermore, a spreader element is provided, which is mounted so as to be movable relative to the expansion screw, wherein the expansion screw can be moved from a release position into a tensioning position by a relative movement of the spreader element. In this case, such a relative movement of the spreading element with respect to the expansion screw can be achieved by a rotational or pivoting movement of the fitting body to which the spreading element is fixed. The fitting body can be rotated or pivoted from a release position, in which the expansion screw is released, into a tensioning position, in which the expansion screw is tensioned. To this end, the fitting body is rotated or pivoted from a first position (release position) to a second position (tension position), wherein this movement is limited by a stop. The expansion screw can be released again by rotating or pivoting the fitting body back from the tensioned position.
A disadvantage of the known prior art is that the operator often uses excessive force to bring the fitting body from the release position into the tensioning position and the stop is rolled over by the excessive force, resulting in the furniture fitting being damaged. It can also happen that, when the fitting body is in the tensioned position, the operator wants to release the fitting body and pushes it in the wrong direction and thus runs over a stop, so that the furniture fitting is likewise damaged.
Disclosure of Invention
The object of the present invention is to provide a furniture fitting for connecting two furniture parts, in which the above-mentioned disadvantages of the prior art are avoided.
This object is achieved by a furniture fitting having the features of claim 1 and by a furniture having the features of
According to the invention, the following settings are set: the fitting body is connected to the at least one spreader element in such a way that the at least one expansion screw is moved from a first release position into a tensioning position by means of a rotational or pivoting kinetic energy of the fitting body in a first operating direction, wherein the at least one expansion screw is movable from the tensioning position into a second release position, which is different from the first release position, by means of a further rotational or pivoting movement of the fitting body in the first operating direction.
This has the advantage that the fitting body can be released in a plurality of directions starting from the tensioned position of the at least one expansion screw and that damage to the furniture fitting due to selection of the wrong operating direction does not occur. Furthermore, the furniture fitting according to the invention has two release positions, wherein the furniture fitting can be moved into different release positions depending on the accessibility of the fastening position.
The following settings can be set: the at least one expansion screw has a central axis and the fitting body can be rotated or pivoted about a rotational axis during a rotational or pivoting movement, wherein the rotational axis is arranged transversely, preferably perpendicularly, to the central axis.
Preferably the following settings are set: the at least one expansion element, preferably on the free end, has an expansion projection, which is arranged in the at least one expansion screw. The following can be provided here: the at least one expansion screw is formed as a sleeve which is at least partially slotted in its longitudinal direction, wherein a spreader element is arranged in the sleeve, wherein a spreader projection is attached to one end of the spreader element. Now, when this spreading projection is pushed in the axial direction (in the direction toward the inside of the sleeve), the expansion screw is spread by the outer surface of the slot of the expansion screw, and therefore, the expansion screw is held in the bore hole in which the expansion screw is disposed by the surface pressure. Now if the expansion element is reset or the expansion projection is moved out of the interior of the expansion screw, the sleeve again returns to its original shape (if the expansion screw is only elastically deformed in the tensioned position) and the expansion screw can again be safely removed from the borehole.
The following can also be provided: the at least one spreader element is rotatably mounted on the at least one fitting body and is axially movable in the at least one expansion screw.
Particularly preferably, the following can be provided: the at least one expansion element is formed as an L-shaped bracket, the first leg of which is axially guided in the at least one expansion screw and the second leg is rotatably mounted in the fitting body. The following can be provided here: the radial movement is converted into an axial movement by a rotational or pivoting movement of the fitting body, wherein the axial movement of the spreader element in the at least one expansion screw causes a tensioning or a release of the expansion screw.
Furthermore, the following can be provided: the at least one expansion screw is connected to the carrier, and the at least one expansion element is mounted on the fitting body so as to be rotatable about a rotational axis. The following settings can also be set: the fitting body has three abutment surfaces, of which always one abuts against the carrier depending on the position of the fitting body, and of which always at least two have different distances from the axis of rotation. Thus, for example, the following can be provided: the carriage bearing against the first bearing surface of the fitting body is moved onto the second bearing surface of the fitting body by a rotational or pivoting movement of the fitting body about the axis of rotation, wherein the two bearing surfaces have different distances from the axis of rotation, and the spreader element is therefore guided axially in the expansion screw by the difference of the different distances, wherein this axial movement of the spreader element can move the expansion screw between the release position and the tensioning position.
Furthermore, the following arrangement can be preferred: by means of a rotational or pivoting movement of the fitting body relative to the at least one expansion screw, the distance between a rotational axis in which the at least one spreader element is rotatably mounted in the at least one fitting body and the at least one expansion screw can be increased or decreased. By increasing or decreasing the distance, as described above, an axial movement of the spreader element in the at least one expansion screw (in which the spreader element is mounted so as to be axially displaceable) can be brought about, which spreader element is mounted rotatably in the at least one fitting body.
The following can also be provided: the fitting body is formed in at least two parts, wherein a fastening part for fastening the at least one expansion element and a guide part are provided, which rests against the at least one expansion screw and/or a carrier, which is connected to the at least one expansion screw. By means of this design it can be provided that different regions of the fitting body are formed by different components, wherein the different regions of the fitting body are often subjected to different requirements. For example, the fitting body may have a fixing part for fixing the at least one spreading element. The requirement for such fixing elements is often high elasticity in order to withstand the high forces generated by the transmission of the distracting element without plastic deformation. Furthermore, the following can be provided: the anchoring element is made of a softer or harder material than the distracting element. As a result, no or less wear is present on the fastening component or on the expansion element, which wear is caused by the continuous movement between the two components. The fixing part can thus be made of plastic, for example, and the expansion element can be made of metal, for example, so that there is the further advantage that only minimal noise is generated in the relative movement between the expansion element and the fixing part. And the guide part can therefore also be made of a different material than the expansion screw bearing against the guide part or the carrier bearing against the guide part.
Preferably the following settings are set: the fitting body has a predetermined latching position relative to the expansion screw at least in the tensioning position, preferably also in the first and second release positions. This snap-lock position ensures the relative position between the fitting body and the expansion screw and prevents unwanted movement out of this position. The following can thus be set: this latching position can be brought about by a cam which latches into a recess provided for this cam in the desired position. However, the following arrangement is also possible: eccentric edges are provided relative to the axis of rotation between the respective positions, which must be overcome when the fitting body is rotated or pivoted relative to the expansion screw from the first position to the second position. By this design, the fitting body snaps or latches in a predetermined position when rotated or pivoted from the first position to the second position.
Particularly preferably, the following can be provided: the fitting body is formed as a holding member for the front panel of the drawer. The fitting body can thus be fastened to the front panel and the connecting device for connecting furniture fittings can be fastened to the side walls of the drawer, wherein the front panel can be releasably connected to the side walls of the drawer by means of the connecting device. It is also fully conceivable: the connecting device is arranged on the front panel and the accessory body is arranged on the side wall of the drawer. In the same way, the following can also be provided: the fitting body is formed as a holding part for a drawer rail, wherein the fitting body can be fixed on a front panel or a side wall of the drawer and the connecting device can be fixed on the drawer rail. The following can also be provided: the drawer rail has a fitting body and the connection device is disposed on a front panel or a side wall of the drawer. The following can also be provided in the same manner: the housing is formed by a furniture fitting for connecting two furniture parts, wherein two parts of the housing are connected to each other by the furniture fitting.
It is also sought to protect a piece of furniture having at least two furniture parts which can be connected to one another by means of at least one furniture fitting according to the invention.
