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 claim 13. Advantageous embodiments of the invention are defined in the dependent claims.

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.

Detailed Description

Fig. 1 shows an exploded view of two furniture parts to be connected by means of an embodiment of a furniture fitting 1 according to the invention. More precisely, the two furniture parts to be connected are the front panel 2 and the side walls 3 of the drawer 17, wherein the furniture fitting 1 has a bore 18 for an expansion screw, which bore is provided for the expansion screw, for the connection by means of the expansion screw 5. This is achieved by the first release position of the furniture fitting 1 shown in fig. 1, in which the expansion screw 5 is released. Furthermore, the furniture fitting 1 shown here has a connecting device 8, which connecting device 8 has a bolt. This connecting means 8 can be locked by means of locking means 19 located in the side wall 3 of the drawer 17. Such locking means 19 are known from the prior art. This locking device 19 usually has a hook element which is releasably locked with the connecting device 8. The first release position of the furniture fitting 1, in which the fitting body 7 of the furniture fitting 1 is tilted to the left, can be clearly seen. This fitting body 7 is connected rotatably or pivotably to the expansion screw 5, wherein by a rotational or pivoting movement of the fitting body 7 the expansion element 6 arranged in the interior of the expansion screw 5 can be moved in the axial direction of the expansion screw 5 and thus the expansion screw 5 can be moved between the tensioning position and the release position. This will be described in more detail in the following figures.

Fig. 2a shows an exemplary embodiment of a furniture fitting 1 according to the invention connected to a front panel 2 in a first release position. As fig. 1 shows, the furniture fitting 1 is inserted with its expansion screw 5 into a bore 18 provided for the expansion screw in the front panel 2 and is held in the first release position.

Fig. 2b shows a detailed view of the furniture fitting 1 of fig. 2a connected to the front panel 2.

Fig. 2c shows the furniture fitting 1 from fig. 2a in a first release position in a perspective view. It is clearly visible here that the furniture fitting 1 has two expansion screws 5, which expansion screws 5 are connected to the carrier block 10. The furniture fitting 1 has a fitting body 7, which fitting body 7 is connected rotatably or pivotably to the carrier base 10. The connecting device 8 (formed as a bolt) is arranged on the fitting body 7. The expansion screw 5 has a central axis 22.

In fig. 3a, the embodiment of the invention of fig. 2a is brought into the tensioning position by a rotational or pivoting movement of the fitting body 7 in the first operating direction 9, so that the expansion screw 5 is tensioned by the spreader element 6 and the furniture fitting 1 and the front panel 2 are connected to one another. The fitting body 7 is here rotated or pivoted about a rotational axis 11 in the first operating direction 9, this rotational axis 11 being transverse to the central axis 22 of the expansion screw 5. More precisely, the axis of rotation 11 in this embodiment is substantially perpendicular to the central axis 22 of the expansion screw 5.

Fig. 3b shows the furniture fitting 1 of fig. 3a in a tensioned position in a detail view.

Fig. 3c shows the furniture fitting 1 from fig. 3a and 3b in a perspective view, so that the parts of the furniture fitting 1 (expansion screw 5, carrier 10, fitting body 7 and connecting device 8) can be seen. In this view, it can also be seen how the expansion screw 5 has an expanded state in the tensioned position.

Fig. 4a shows an embodiment according to the invention of the furniture fitting 1 of fig. 3a to 3c, in which the fitting body 7 is brought into the second release position by a rotary or pivoting movement in the first operating direction 9, wherein in this case the furniture fitting 1 is still arranged in the bore 18 of the front panel 2 by means of the expansion screw 5 of the furniture fitting 1, but the furniture fitting is no longer held in the bore 18 by the expansion of the expansion screw 5.

In this case, the fitting body 7 is once again rotated or pivoted about a rotational axis 11 in the first operating direction 9, this rotational axis 11 being transverse to the center axis 22 of the expansion screw 5.

Fig. 4b shows a detailed view of the furniture fitting 1 of fig. 4 a.

Fig. 4c shows a view of the furniture fitting 1 in the second release position, in which again the connecting device 8 on the fitting body 7 is clearly visible, wherein the fitting body 7 is connected rotatably or pivotably to a carrier 10, which carrier 10 is connected to the two expansion screws 5. The expansion screw 5 is clearly visible in this figure in the released (unexpanded) position.

Fig. 5 shows a connection of two furniture parts by means of an embodiment of the furniture fitting 1 according to the invention. In this case, the furniture fitting 1, which is connected to the front panel 2 as a result of the tensioned position (as shown in fig. 3a and 3 b), is inserted into the locking device 19 of the side wall 3 and is locked by the locking device 19.

Fig. 6 shows an exploded view of an embodiment of a furniture fitting 1 according to the invention. The furniture fitting has a carrier 10, to which carrier 10 two expansion screws 5 are fastened. The expansion elements 6 (each expansion element 6 being associated with one expansion screw 5) have an expansion projection 20 on one end. In the assembled state, the expansion elements 6 are arranged with the legs of the expansion elements 6 inside the expansion screw 5, the expansion projections 20 being located on the ends of the legs. The other end of the spreading element 6, which is formed in an L-shape, is fixed in the fixing part 15. In this embodiment, the fitting body 7 is formed by a fixing part 15 and a guide part 16, wherein the guide part 16 carries the connecting device 8 formed as a peg. In the assembled state, the fixing member 15 is inserted into the guide member 16. In the assembled state, the carrier 10 is guided or held on the guide part 16 by the expansion element 6 (more precisely by the expansion projection 20 arranged in the expansion screw 5) by means of the fixing part 15, so that a rotational or pivotal movement of the fitting body 7, more precisely of the fixing part 15 and the guide part 16, relative to the expansion screw 5 or the carrier 10 is permitted. The legs of the spreader element 6 allow a translational movement of the expansion screw 5 and of the carriage 10 connected to the expansion screw 5. The expansion screw 5 has a central axis 22.

Fig. 7a, 8a and 9a show the already described exemplary embodiment of the furniture fitting 1 according to the invention. The furniture fitting 1 is moved from the first release position (as shown in fig. 7 a) into the tensioning position (as shown in fig. 8 a) by a rotational or pivotal movement kinetic energy in the first operating direction 9. By a further rotational or pivoting movement of the fitting body 7 in the first operating direction 9, the furniture fitting 1 can be moved into a second release position (as shown in fig. 9 a). The fitting body 7 is here rotated or pivoted about a rotational axis 11 in the first operating direction 9, this rotational axis 11 being transverse to the central axis 22 of the expansion screw 5. More precisely, the axis of rotation 11 in this embodiment is substantially perpendicular to the central axis 22 of the expansion screw 5.

In fig. 7a, the furniture fitting 1 is shown in the release position. Fig. 7b shows the section indicated in fig. 7 a. It is clear from this sectional view that: how the expansion screw 5 of the furniture fitting 1 is arranged in the bore hole 18 of the front panel 2. The expansion element 6 is arranged with an expansion projection 20 in the center of the expansion screw 5, wherein the expansion element 6 can be moved about the axis of rotation 11. The expansion screw 5 is connected to the carrier block 10, the fitting body 7 resting with its first resting surface 12 on the carrier block 10. The fitting body 7 is configured to rotate or pivot about an axis of rotation 11. The expansion screw 5 is at a distance d from the axis of rotation 11. The furniture fitting 1 can be transferred from the first release position into the tensioning position by a rotary or pivoting movement of the fitting body 7 in the first operating direction 9.

The tensioned position of the furniture fitting 1 is shown in fig. 8 a. Similarly, the cross-section shown in FIG. 8a is shown in FIG. 8 b. In fig. 8b can be seen: how the fitting body 7 is transferred from its first abutment surface 12 on the carrier block 10 to its second abutment surface 13 on the carrier block 10 by a rotational or pivoting movement of the fitting body 7 in the first operating direction 9. The second contact surface 13 is at a greater distance D from the axis of rotation 11 than the first contact surface 12, so that the expansion element 6 fixed to the fitting body 7 moves axially in the expansion screw 5. More precisely, the expansion elements 6 are pulled with their expansion projections 20 into the interior of the expansion screw 5, so that the expansion projections 20 expand the expansion screw 5. This is done by increasing the distance D (shown by fig. 7 b) between the expansion screw 5 and the rotation axis 11 to a distance D (shown in fig. 8 b). By spreading apart, the expansion screw 5 is pressed with its circumferential surface against the inside of the bore 18 of the front panel 2, so that the furniture fitting 1 is held on the front panel 2 by the pressing force acting between the expansion screw 5 and the bore 18.

By further rotating or pivoting the fitting body 7 in the first operating direction 9, the furniture fitting 1 is moved into a second release position, which is different from the first release position. This second release position of the furniture fitting 1 is shown in fig. 9 a.

Fig. 9b again shows the section indicated in fig. 9a, wherein it can be seen that the fitting body 7 now bears with its third bearing surface 14 against the carrier 10, in this embodiment the third bearing surface 14 being at a reduced distance d from the axis of rotation 11 compared to the second bearing surface 13. More precisely, the third abutment surface 14 is at the same distance d from the axis of rotation 11 as the first abutment surface 12. By further rotating or pivoting the fitting body 7 in the first operating direction 9, the distance D is reduced to a distance D, so that the expansion element 6, to be precise the expansion projection 20, is pushed out of the expansion screw 5 and the expansion screw 5 is released again.

Fig. 10a shows an embodiment of a furniture fitting 1 according to the invention in the tensioned position. A front view of the furniture fitting 1 is shown in fig. 10 a. In fig. 10a, two expansion screws 5 are visible, which expansion screws 5 are connected to the carrier block 10. The section B-B represented in fig. 10a is shown by the view of fig. 10B. This cross-section is well visible: how the carrier 10 connected to the expansion screw 5 rests on the second resting surface 13 of the fitting body 7. The carriage 10 rests against the second contact surface 13 on the guide part 16, since in this embodiment the fitting body 7 is formed in two parts, namely the guide part 16 and the fastening part 15. The fixing part 15 arranged in the guide part 16 has a rotational axis 11, about which rotational axis 11 the spreader element 6 is rotatably mounted.

Fig. 10C shows a detail C of fig. 10b, in which the carriage 10 is again shown resting against the second resting surface 13 of the guide part 16. In this figure it is clearly visible that, due to the abutment of the carriage 10 against the second abutment surface 13, a distance E exists between the axis of rotation 11 and the carriage 10.

By rotating or pivoting the fitting body 7 in the first operating direction 9, to be precise by rotating or pivoting the guide part 16 and the securing part 15 connected to the guide part 16 in the first operating direction 9, the furniture fitting 1 shown in fig. 10a to 10c can be transferred into a second release position, which is shown in fig. 11 a.

In fig. 11a it can be clearly seen how the expansion screw 5 and the carrier 10 connected to the expansion screw 5 are now in a pivoted or tilted position relative to the fitting body 7. Fig. 11B shows a section B-B indicated in fig. 11 a. Detail C shown in fig. 11b is shown by fig. 11C. In fig. 11c it can be seen: how the carriage 10 abuts against the third abutment surface 14 of the guide member 16 and is thus at a distance E from the axis of rotation 11, which distance E is a distance that decreases with respect to the distance E. The expansion element 6 is in turn mounted in the axis of rotation 11, more precisely in the fixing part 15, wherein the fixing part 15 is received by the guide part 16. The fixing part 15 and the guide part 16 together form the fitting body 7.

By means of the rotatable or pivotable mounting of the spreader element 6, the spreader element 6 can be moved rotationally during a rotational or pivotal movement of the fitting body 7 (more precisely the securing part 15 and the guide part 16). The expansion element 6 formed in an L-shape is axially displaced in the expansion screw 5 by a rotational or pivoting movement between the carrier block 10 or the expansion screw 5 and the axis of rotation 11 causing the distance e to change. The expansion or release of the expansion screw 5 can be effected by an axial displacement of the expansion element 6 in the expansion screw 5. In this exemplary embodiment, this is achieved by the expansion screw 5 being slotted, wherein the expansion element 6 has an expansion projection 20 at the free end (projecting beyond the expansion screw 5). If this expansion projection 20 is now pushed into the expansion screw 5 by means of the expansion element 6, the slotted expansion screw 5 is expanded and the circumferential surface of the expansion screw 5 is enlarged. If the expansion screw 5 is now arranged in a bore 18 provided for the expansion screw, a contact pressure is built up between the bore 18 and the circumferential surface of the expansion screw 5 by the expansion of the expansion screw 5. If now the expansion projection 20 or the expansion element 6 is pushed out of the expansion screw 5 again, the expansion screw 5 springs back into its initial position and reduces its circumference, so that the expansion screw 5 can be easily removed from the borehole 18 again. The resilience of the expansion screw 5 can be achieved by a suitable choice of the material for the expansion screw 5, wherein it should be noted that the expansion of the expansion screw 5 is always in the elastic deformation range, so that the expansion screw 5 springs back again to its initial position with its own force when the force is withdrawn (removal of the spreading element 6).

Furthermore, it can be provided that the fitting body 7 has a predetermined latching position relative to the at least one expansion screw 5 at least in the tensioning position (preferably also in the first and second release positions). This is clearly visible in fig. 10a to 10c and 11a to 11c, wherein an eccentric rounded edge 21 is formed between the first abutment surface 12 and the second abutment surface 13 of the guide part 16 and between the second abutment surface 13 and the third abutment surface 14 of the guide part 16. When a rotational or pivoting movement is carried out between the first abutment surface 12 and the second abutment surface 13 or between the second abutment surface 13 and the third abutment surface 14, the carrier 10 resting on the abutment surfaces must now pass over this eccentric rounded edge 21, so that the spreader element 6, more precisely the spreader nose 20, in the expansion screw 5 is pushed into the expansion screw 5. However, since the expansion screw 5 has an elastic deformation, a restoring spring force is exerted by this expansion screw 5 on the expansion element 6, since the expansion screw 5 always tends to return to its initial position. If this eccentric rounded edge 21 is now passed over, the distance is again reduced and the expansion element 6 is pushed slightly into the expansion screw 5 or pushed out of the expansion screw 5 by the restoring spring force of the expansion screw 5. The minimum distance to the axis of rotation 11 is therefore always in the middle of the abutment surfaces 12, 13, 14. The distance is always increased when the abutting carrier 10 is moved away from this intermediate position of the abutment surfaces 12, 13, 14. However, since the expansion screw 5 has a restoring spring force, the expansion screw 5 always forces the smallest possible distance between the carrier 10 and the axis of rotation 11, so that a predefined latching position is always provided in the center of the contact surfaces 12, 13, 14. In this case, the fitting body 7 is rotated or pivoted about a rotational axis 11 in the first operating direction 9, which rotational axis 11 is transverse to the center axis 22 of the expansion screw 5. More precisely, the axis of rotation 11 in this embodiment is substantially perpendicular to the central axis 22 of the expansion screw 5.

Fig. 12a to 14b show an embodiment of a furniture fitting 1 according to the invention, wherein the fitting body 7 is formed as a holding part for a drawer rail 4. Here, in fig. 12a, the fitting body 7 is arranged in the first release position. By a rotational or pivoting movement of the fitting body 7, which is arranged in the first release position in fig. 12a, in the first movement direction 9, the expansion screw 5 can be transferred into a tensioning position, which is shown in fig. 13 a. By continuing the rotational or pivotal movement of the fitting body 7 in the first operating direction 9, the expansion screw 5 can be moved from the tensioning position into a second release position, which is different from the first release position. This second release position is shown in fig. 14 a. Fig. 12b, 13b and 14b show a detail a represented in fig. 12a, 13a and 14a, respectively.

More specifically, in fig. 12b it can be seen that the expansion screw 5 is in the first release position. The expansion screw 5 is fixed to a carrier 10, which carrier 10 rests against the fitting body 7. This exemplary embodiment has the same function as in the preceding figures, wherein also in the expansion screw 5 an L-shaped expansion element 6 is arranged, which can be moved axially in the expansion screw 5. The spreading element 6 formed in an L-shape is also pivotably fixed in the fitting body 7. This embodiment, more precisely the fitting body 7, also has a first abutment surface 12, a second abutment surface 13 and a third abutment surface 14, wherein at least two of the abutment surfaces 12, 13, 14 are at different distances D, D from the axis of rotation 11. More precisely, the first abutment surface 12 and the third abutment surface 14 have the same reduced distance d. The second abutment surface 13 has an increasing distance D. In the position shown in fig. 12b, the carrier 10 rests against the first contact surface 12 by a distance d, so that the expansion element 6 is in the pushed-out position in the expansion screw 5 by its expansion projection 20, which is arranged at the free end, and the expansion screw 5 is held in the first release position.

Fig. 13b shows the tensioning position of the expansion screw 5, which can be seen by the form of the expansion screw 5 being expanded. For this purpose, the fitting body 7 is rotated or pivoted relative to the carriage 10 in the first operating direction 9, the carriage 10 now bearing against a second bearing surface 13 of the fitting body 7, which is at an increasing distance D from the axis of rotation 11. By this increased distance D, the expansion element 6 is pulled into the interior of the expansion screw 5, so that the expansion projections 20 fixed to the free end of the expansion element 6 expand the expansion screw 5.

By a further rotational or pivoting movement of the fitting body 7 in the first operating direction 9, the expansion screw 5 can be transferred again from the tensioning position into a second release position, which is shown in fig. 14 b. It is clearly visible here how the carriage 10 now rests against a third resting surface 14 of the fitting body 7, which third resting surface 14 is at a further reduced distance d from the axis of rotation 11, so that the spreading element 6 is pushed out of the expansion screw 5 and the expansion screw 5 springs back into its initial position (or second release position).

In fig. 12a to 14b, the fitting body 7 is formed integrally with the inner part of the drawer rail 4. The drawer rail 4 can be connected to a counterpart by its end opposite the expansion screw 5, as is known in the art. The drawer rail 4 can connect two parts of the drawer 17 and can optionally run parallel to and above the side wall 3 of the drawer 17.
