EP3072417B1 - Pull-out guide for furniture parts which can be extended from and inserted into a furniture body - Google Patents

Description

The present invention relates to a pull-out guide according to the preamble of patent claim 1.

A pull-out guide of the type mentioned above is from the DE 90 07 365 U1 known. Pull-out guides serve to store furniture parts, such as drawers, pharmacist cabinets, other drawers and pull-outs, in a furniture carcass in such a way that they can be pulled out of the furniture carcass and inserted again into the furniture carcass. When inserting or pulling out the furniture parts, the rails of the pull-out guide are pushed into each other or pulled apart. The retraction mechanism is usually used to automatically pull the furniture part at the end of the insertion movement completely into the furniture body to ensure that the furniture parts reach their fully inserted position safely. Examples of pull-out guides with retraction mechanism are also in the EP 2 174 570 B1 shown. In the prior art, the retraction mechanism is mounted above and / or below the carcass rail on this. This is also in the embodiments of EP 2 174 570 B1 and the DE 90 07 365 U1 so provided. In the EP 2 174 570 B1 engages the tilt slide of the retraction mechanism through a slot in the drawer rail, which is arranged in the operating position of the pull-out in a horizontally extending wall portion of the carcass rail. In the DE 90 07 365 U1 the retraction mechanism is arranged in a slot which, seen in the operating position, is located both in a horizontal and in a vertical wall section of the carcass rail.

The problem is the use of pull-outs of said, known in the art, when very flat furniture parts or drawers in the furniture body to be arranged. The provided in the prior art Arrangement of the retraction mechanism on the carcass rail limits the desired flat design.

The object of the invention is to improve a pull-out guide of the type mentioned above in such a way that this problem is eliminated.

For this purpose, a pull-out according to claim 1 is proposed.

As a result of the arrangement of the slot through which the tilting slide engages, in a wall section of the carcass rail which is vertically extended in the operating position, the tilting slide and the retraction mechanism no longer necessarily have to be arranged above or below the carcass rail. It is thereby possible to see the pull-out guide in its operating position, to build much smaller in its vertical extension, so that the pull-out is also suitable for appropriately flat built, pulled out of the furniture body and back into this insertable furniture parts. In other words, the space required for the pull-out guide in the vertical direction is thus reduced by the invention. The furniture components which can be inserted into and removed from the furniture body may, as known in the art, be e.g. to draw drawers, pharmacist cabinets but also to other inserts or extracts.

In the case of a vertically extending wall section of the carcass rail, the vertical extent of this wall section is significantly greater than the thickness or material thickness of this wall section. It is different with horizontally extended wall sections. There, the horizontal extent is significantly greater than the thickness or material thickness of the wall portion.

The slot in the vertically extending wall portion of the carcass rail is conveniently formed longitudinally parallel to the direction of insertion. In preferred embodiments, the tilting slide is slidably mounted along this slot. The notion of the slot, however, should be noted that this is to be understood in general. You could also generally speak of one Recess speak. This recess or the slot can have very different embodiments. In preferred embodiments, however, the slot in the vertically extending wall portion of the carcass rail is formed in the form of a long hole closed on both sides at its longitudinal ends.

The retraction mechanism is preferably fastened to the carcass rail and / or carried by the carcass rail. A particularly flat construction of the pull-out guide is possible if the pull-in mechanism is arranged on a first side of the wall section of the carcass rail vertically extending in an operating position of the pull-out guide and the drawer rail is arranged on a second side of this wall section of the carcass rail opposite the first side. In other words, the pull-in mechanism is preferably arranged on the side of the carcass rail opposite the other rails of the pull-out guide.

Pull-out guides according to the invention are designed as so-called full pull-outs. In this case, the drawer rail is mounted displaceably indirectly in the carcass rail by a so-called middle rail is still present between drawer rail and carcass rail. In the invention it is provided that the pull-out comprises at least one middle rail, wherein the drawer rail is slidably mounted in the middle rail in the pull-in direction and against the pull-in direction and the middle rail is slidably mounted together with the drawer rail in the carcass rail in the pull-in direction and against the pull-in direction , In such full extensions, the movement of the center rail and the drawer rail can be synchronized by known synchronization devices. For this purpose, it is possible to resort to technologies of the prior art. The same applies to the question of how the drawer rail is slidably mounted in the carcass rail or in the middle rail and the possibly present center rail is slidably mounted in the carcass rail. Also for this purpose various known in the prior art storage forms can be applied. For example, rolls or Ball bearing conceivable. Even plain bearings can be designed as in the prior art. However, the pull-out guide is particularly preferably a so-called roller pull-out, in which the individual rails are displaceably mounted on one another by means of rollers.

The carcass rail may be a component initially separate from the furniture body, which is then secured in the furniture body with known in the prior art means. But just as well, the carcass rail can already be integrated into a furniture carcass or part of it. This also falls under the concept of attachment of the carcase rail on the furniture body. The same applies to the shop rail. These may also be a rail initially executed separately, which is then attached to the furniture part. The drawer rail can also already in the furniture part such. the drawer be integrated and thus be attached to this or this.

In the case of the full extension, the pull-out mechanism can be provided on one or the first side of the wall section of the carcass rail vertically extending in an operating position of the pull-out guide and the middle rail on a second side of this wall section opposite the first side Carcass rail are arranged. In the invention it is provided that an additional slot in a, in an operating position of the pull-out vertically extending wall portion of the center rail is arranged and the tilting slide engages through the additional slot. When vertically extending wall portion of the center rail, it is again such that the vertical extent of this wall portion of the center rail is significantly larger than the thickness or material thickness of this wall portion.

It should also be pointed out, with regard to the additional slot, that the slot is generally a recess, which can be designed and shaped differently. Again, the term of the slot is therefore very general in the sense of a recess to understand. In preferred embodiments the additional slot in the form of a closed on both sides at its longitudinal ends long hole. But it is equally conceivable that the additional slot is formed in the form of a closed on one side at one of its longitudinal ends and open at the opposite longitudinal end slot. Preferably, the additional slot is formed longitudinally parallel to the direction of insertion. The tilting slide can also be displaceably mounted along the additional slot.

For the formation of the retraction mechanism itself can be used in the basic construction essentially to various proposals from the prior art. Preferably, the retraction mechanism has at least one pull-in spring for carrying out a pull-in movement of the tilting slide and / or at least one damper for damping one or the pull-in movement of the tilting slide. As is known per se in the prior art, the tilting slide of the retraction mechanism can be displaceably and tiltably mounted in or on at least one longitudinally extended guideway of the retraction mechanism which is bent and bent in at least one end region. This at least one guideway may e.g. be formed slot or groove-shaped. It may be in the guideway but also guide rails or the like. Again, all known in the prior art embodiments can be used.

In the context of the invention it is possible to design pull-out guides with only one tilting slide. However, particularly preferred embodiments of the invention provide that the pull-out guide has at least one additional tilt slide. This does not necessarily have to be part of the retraction mechanism. Rather, it is also possible that the additional tilt slide is slidably and tiltably mounted in an additional guide, wherein this additional guide to another rail of the pull-out as the carcass rail, for example on the center rail, fastened or attached. In such embodiments, it is possible that the Einziehmechanismus on a first side of a, in an operating position of the pull-out vertically extending wall portion of Carcass rail and the drawer rail, and possibly also the center rail, are arranged on a first side opposite the second side of this wall portion of the carcass rail.

As already explained above with respect to the tilting slide, the additional tilting slide can also be displaceably and tiltably mounted in or on at least one longitudinally extended and bent in at least one end region or angled, preferably slot-shaped or groove-shaped guideway ,

The tilting slide and the additional tilting slide can engage in one another through a slot in the carcass rail and optionally also through an additional slot in the middle rail. The way in which this interaction takes place or is carried out concretely can be very different. In general, one could also speak of fastening or detachment from one another. It may be a mechanical, preferably frictional or positive engagement. But just as well, other connection forces can be used, such as a magnetic fastening together or an electrostatic fastening together or the like. The concept of interlocking is therefore to be understood accordingly. Particularly preferably, however, it is provided that the additional tilting slide has a first jaw for releasable engagement in a claw of the tilting slide of the retraction mechanism and at least one second jaw for releasable engagement in a contact element on one of the rails of the extension guide, preferably on the drawer rail. Again, the term of the claw or the releasable engagement according to the previous statements is generally understood. In fact, a jaw can be a fork-like embodiment, which is provided for a positive engagement with another jaw or in the contact element on one of the rails. But here are also other form-fitting or frictional or based on other connection forces connections possible, such as the aforementioned electrostatic or magnetic releasably fasten together. The concept of Claw in this context could therefore also be replaced by a fastener in general and is to be understood as general.

In preferred embodiments of the additional tilting slide it is provided that the first jaw and the second jaw are arranged on opposite sides of a pivot axis about which the additional tilting slide is pivotable. In this pivot axis may be a physically existing axle or the like but also an imaginary pivot axis. With pull-out guides with tilting slide and additional tilt slide, there are preferably different operating states.

A first operating state may, for example, consist in that the additional tilting slide engages with its first claw in the claw of the tilting slide of the retraction mechanism and engages with its second claw in the contact element on one of the rails of the extension guides. This operating state is preferably realized at the end of a pull-in movement or at the beginning of a pull-out movement of the furniture part into or out of the furniture carcass. In a second operating state can then be provided that, preferably by tilting or pivoting of the claw of the tilting slide, the first jaw of the additional tilting slide releases the claw of the tilting slide, while the second jaw of the additional tilting slide but still in the contact element at a the rails of the pull-out guide engages. This second operating state preferably follows the first operating state when the furniture part is removed from the furniture body. On the other hand, the two tilting slide when inserting the furniture part in the furniture body before the first operating state are preferably in the second operating state. In a third operating state is then conveniently provided that both the first jaw of the additional tilting slide is released from the claw of the tilting slide of the retraction mechanism, and the second jaw of the additional tilting slide is released from the contact element on one of the rails. This third operating state conveniently follows when pulling the furniture part from the furniture body to the second Operating condition. When inserting the furniture part from the fully extended position into the furniture body in, the tilting slide are the other way preferably only in the third, then in the second and then in the first operating state.

Further features and details of preferred embodiments of the invention will be explained by way of example with reference to the description of the figures. Show it:

• Fig. 1 to 18 Representations of a first embodiment of the invention in the form of a full extension and
• Fig. 19 to 22nd Representations of a second embodiment of the invention in the form of a full extension.

In the Fig. 1 and 2 the first embodiment of the invention is shown in a state in which the drawer rail 3 of the pull-out 1 is fully inserted or retracted together with the middle rail 11 in the direction of insertion 6 in the carcass rail 2. In Fig. 3 the drawer rail 3 and the middle rail 11 are completely pulled out of the carcass rail 2 counter to the pull-in direction 6. Fig. 4 shows the drawer rail 3 detached from the other rails and arranged here on the drawer rail 3 contact element 23. Die Fig. 5 to 8 show various representations of the carcass rail 2 together with the retraction mechanism 4 without the other rails. The FIGS. 9 and 10 show the center rail 11 in two different views. The Fig. 11 to 16 serve to illustrate the operation of the tilt slide 5 and the additional tilt slide 19 in different operating conditions. These are in each case partially sectional representations in order to better illustrate the tilting slides 5 and 19. The FIGS. 17 and 18 show the components of the retraction mechanism 4 in an exploded view and in addition the additional guide 25 with the additional tilt slide 19 detached from the rails 2, 3 and 11 of the pull-out. 1

For the sake of completeness, it is pointed out that neither the furniture body nor the furniture part which can be pushed into and pulled out of it by means of the pull-out guide 1 are shown in the figures. The arrangement and attachment of the pull-out guide 1 with its rails 2, 3 and 11 between the furniture body and furniture part can be carried out as known per se. Usually located on opposite sides of the furniture part respectively a pull-out 1. In the figures shown here, only one of these two pull-out guides 1 is shown in each case, which together store a piece of furniture in accordance with the furniture body.

In the embodiment shown here is a so-called Rollenausziehführung 1, in which the rails 2, 3 and 11 are guided by means of rollers 28 slidably into each other. The drawer rail 3 is slidable in the middle rail 11 and the center rail 11 is slidably mounted together with the drawer rail 3 in the carcass rail 2. The insertion and withdrawal takes place in the direction of insertion 6, the extraction of the furniture part of the furniture body in the direction of insertion 6 opposite direction. In the Fig. 9 Particularly well visible synchronization roller 33, together with the roller 28 arranged above it, ensures the synchronization of the pull-out movement between the drawer rail 3 and the center rail 11, as is known per se and need not be explained further. For the sake of completeness, it is pointed out that pull-out guides 1 according to the invention do not necessarily have to be roll-based. Instead of the rollers 28, for example, ball bearings or plain bearings can be used, just to name a few examples. The synchronization of drawer rail 3 and middle rail 11 may be configured differently or omitted altogether.

The retraction mechanism 4 is fixed to the carcass rail 2 and is thereby supported by the latter. The retraction mechanism 4 is, as particularly well based on FIGS. 5 and 6 can be seen on a first side 9 of the in the operating position of the pull-out 1 vertically extending wall portion 8 of the carcass rail 2 is arranged. The drawer rail 3, as well as in this embodiment, the Middle rail 11, are located on one of the first side 9 opposite second side 10 of this wall portion 8 of the carcass rail 2. In the in the operating position of the pull-out 1 vertically extending wall portion 8 of the carcass rail 2, the slot 7 is arranged. In the illustrated embodiment, it is elongated parallel to the direction of insertion 6. The tilting slide 5 of the retraction mechanism 4 engages through the slot 7 in the carcass rail 2, as is particularly well in the Fig. 5 and 7 can be seen. From the comparison of these two figures is also clear that the tilting slide 5 is slidably mounted along the slot 7. The function of the claw 21 of the tilting slide 5 of the retraction mechanism 4 will be explained in more detail below. In the illustrated embodiment, the slot 7 is designed as a limited by the longitudinal ends 44 slot.

The retracting mechanism 4 operating the tilting slide 5 can be designed very differently. For this purpose, various variants are known in the prior art. In particular with reference to the FIGS. 17 and 18 For example, the retraction mechanism 4 used here has a first slide part 29 and a second slide part 30 mounted to be displaceable in the direction parallel thereto with respect to the retraction direction 6. The first slide part 29 is fastened or fixed on the first side 9 on the vertical wall section 8 and thus on the carcass rail 2. On the first slide part 29, pins 31 are arranged, which engage in the guide grooves 32 of the second slide part 30. About these guides by means of pins 31 and guide grooves 32, the displaceable mounting of the second slide member 30 is carried on the first slide member 29. Of course, displaceable bearings can be carried out differently at this point.

The tilting slide 5 is pivotally attached to the second slide part 30 by means of the pins 42, so that it can be pivoted on the one hand about the pins 42 and on the other hand forcibly with the second slide member 30 relative to the first slide member 29 and thus also relative to the carcass rail 2 is moved. The pins 42, like the second pins 43 of the tilting slide 5, engage in the guide tracks 18, which are designed as oblong holes, on the first slide part 29. The End portions 17 of the guideways 18 are, as is known, angled or bent executed. If the pins 43 of the tilting slide 5 move relative to the first slide part 29 relative to the first slide part 29 and thus to the carcass rail in the end regions 17, this automatically leads to a tilting or pivoting of the tilting slide 5 about the pins 42 or the pins defined thereby pivot axis.

The pull-in mechanism 4 driving catch spring 15 has the ends 37 and 38 on. With the end 37, the pull-in spring 15 is fixed in the suspension point 39 and thus in the second slide part 30. The opposite end 38 of the pull-in spring 15 is suspended in the suspension point 41 of the first slide part 29, so that the two slide parts 29 and 30 can be clamped by means of the pull-in spring 15 against each other. In addition to the pull-in spring 15, the pull-in mechanism 4 realized here, as known per se, also has a damper 16. In the embodiment shown is a linear damper, in which the piston rod 36 and the cylinder 35 are moved in a longitudinal direction relative to each other. Suitable dampers are known in the furniture industry and need not be further explained here. In other embodiments, the linear damper 16 shown here could also be replaced by a rotary damper or other dampers.

The piston rod 36 of the damper 16 is fastened in the suspension point 40 on the second slide part 30, while the cylinder 35 is fixed in a corresponding receptacle 45 of the first slide part 29. This has the consequence that the damper 16 unfolds its damping effect during a relative movement between the first slide part 29 and the second slide part 30.

The pull-out guide 1 shown here also has the additional tilt slide 19 in addition to the tilt slide 5. This is guided and stored in the additional guide 25 in this embodiment. The additional guide 25 is fixed to the vertically extended wall portion 13 of the center rail 11. The guidance and storage of the additional tilt slide 19 via an intervention of the additional tilt slide 19 fixed pin 34 in the here also groove-shaped guideways 27 with their angled or bent arranged end portions 26. As long as all pins 34 are outside the end portion 26, the additional tilt slide 19 is guided linearly displaceable in the additional guide 25. If the pins 34 intended for this purpose enter the angled or bent end regions 26, then the tilting or pivoting of the additional tilting slide 19 about its in the Fig. 11 to 16 drawn pivot axis 24. The additional tilt slide 19 has a first jaw 20 for releasable engagement in the jaw 21 of the tilt slide 5 of the retraction mechanism 4 and a second jaw 22 for releasable engagement in the contact element 23 on one of the rails, here on the drawer rail 3, on ,

In order for the first jaw 20 of the additional tilting slide 19 to be able to engage with the claw 21 of the tilting slide 5, an additional slot 12 is provided in the vertically extending wall section 13 of the middle rail 11, which slot of this first embodiment is closed off by the longitudinal ends 14 in the form of a double-sided Long hole is limited. Also, the additional slot 12 is formed longitudinally parallel to the direction of insertion 6. The additional tilt slide 19 is slidably mounted in it parallel to the direction of insertion 6.

For the operation of the retraction mechanism 4 and its interaction with the additional tilt slide 19 is on the Fig. 11 to 16 which will now explain the various operating conditions. The FIGS. 11 and 12 show the first operating state in which the tilting slide 5 engages with its claw 21 in the first jaw 20 of the additional tilt slide 19 and the additional tilt slide 19 engages with its second jaw 22 in the contact element 23. In the FIGS. 11 and 12 are the drawer rail 3 and the center rail 11 completely retracted in the direction of insertion 6 in the body rail 2. If one now draws from this situation according to the FIGS. 11 and 12 the furniture part together with the drawer rail 3 and the synchronization by means of the synchronization roller 33 with the center rail 11 a bit far out, the first operating state is initially maintained by the tilt slide 5 along the linear portion of the guideways 18 of the additional tilt slide 19, which is yes fixed to the center rail 11, is moved. During this movement of the tilting slide 5, the second slide part 30 is forcibly displaced parallel to the pull-in direction 6 against the first slide part 29, whereby the catch spring 15 clamped between them is tensioned. If the pins 43 fall into the angled or bent end regions 17 of the guideways 18 during this pull-out movement, the tilting slide 5 is thereby forcibly pivoted about the first pins 42 on the one hand, and then via the engagement of the pins 43 in the end regions 17 in this pivoted position fixed. The claw 21 of the tilting slide 5 thereby releases the first jaw 20 of the additional tilting slide 19, whereby the first operating state ends.

It follows the second operating state, which in the FIGS. 13 and 14 is shown. In this, the first jaw 20 of the additional tilting slide 19 and the claw 21 of the tilting slide 5 of the retraction mechanism 4 are no longer engaged with each other. However, the second jaw 22 of the additional tilting slide 19 is still in engagement with the contact element 23 and thus with the drawer rail 3. In this operating state, the additional tilt slide 19 is now initially along the linear in the further pulling out of the drawer rail 3 against the insertion direction Area of the guideways 27 moved in the additional guide 25. Now reach the front pin 34 of the additional tilt slide 19, the angled or bent end portions 26 of the guideways 27, so the additional tilt slide 19 is forcibly pivoted about its pivot axis 24. As a result, the second jaw 22 of the additional tilting slide 19 releases the contact element 23, whereby the third operating state according to FIG FIGS. 15 and 16 is reached. By the engagement of the front pin 34 of the additional tilt slide 19 of the additional tilt slide 19 remains in the in FIGS. 15 and 16 shown position while the drawer rail 3 and the center rail 11 are further pulled out against the pull-in 6. The additional tilt slide 19 now remains in the third operating state according to the FIGS. 15 and 16 until the contact element 23 during insertion of the drawer rail 3 and the middle rail 11 in the body rail 2 in the direction of insertion 6 on the second jaw 22nd the additional tilt slide 19 hits. As a result of this collision, the front pins 34 of the additional tilt slide 19 are pulled out of the angled or bent end regions 26 of the guideways 27 by the additional tilt slide 19 being pivoted about the pivot axis 24. It then results in the situation, as in the FIGS. 13 and 14 is shown. By further insertion of the drawer rail 3 and the center rail 11, the collision of the first claw 20 of the additional tilting slide 19 with the claw 21 of the tilting slide 5 of the retraction mechanism 4 occurs later. The tilting slide 5 is thereby pivoted back. Its pins 43 are thereby pivoted out of the bent or angled end portions 17 of the guideways 18, whereby the tilting slide 5 is released. In this state, then the biased catch spring 15 pulls the tilt slide 5 together with the second slide part 30 in the direction of insertion 6 into the in the FIGS. 11 and 12 shown starting position. This results in an automatic retraction of the drawer rail 3 and the center rail 11 to the fully retracted position according to the FIGS. 11 and 12 ,

While in the previously described first embodiment, as set forth, in addition to the tilt slide 5 of the retraction mechanism 4 also an additional tilt slide 19, which is arranged on the additional guide 25 on the center rail 11, is present in the two embodiments described below on the additional Tilting slide 19 and thus also waives the additional guide 25. However, the retraction mechanism 4 itself is designed in the same way in its construction and in its function in both embodiments described below, as has been explained in detail with reference to the first embodiment. In the embodiment shown below, the tilting slide 5 of the retraction mechanism 4 engages with its claw 21 directly into the contact element 23, which in turn is fixed in each case to the drawer rail 3. For this purpose, the tilting slide 5, as explained below, different far beyond the slot 7 and in the second embodiment according to the Fig. 19 to 22nd also protrude beyond the additional slot 12.

Now, first, the second embodiment according to the Fig. 19 to 22nd explained. Only the differences from the first embodiment will be discussed. With regard to all other features, reference is made to the description of the first embodiment.

In the second embodiment according to the Fig. 19 to 22nd it is also a full extension, in which the pull-out guide 1 has a carcass rail 2, a drawer rail 3 and a middle rail 11 mounted therebetween. The contact element 23 is, as I said, also fixed to the drawer rail 3 here. It is also a Rollenausziehführung 1 with synchronization of the extension movement of the drawer rail 3 and the middle rail 11. In contrast to the first embodiment, no additional tilt slide 19 is present. Instead, the additional slot 12 in the vertically extending wall portion 13 of the center rail 11 is open to the rear. As especially good when fully extended according to Fig. 22 is visible, the additional slot 12 has only one closed longitudinal end 14, while it is open at the opposite longitudinal end 14. As a result, the tilting slide 5 can be moved out of the additional slot 12 via the open end when the middle rail 11 is pulled out of the carcass rail 2 correspondingly far opposite to the pull-in direction 6. When reinserting in the direction of withdrawal 6, the tilting slide 5 can then retract again via the open end 14 into the additional slot 12.

Fig. 19 shows the first operating state of the retraction mechanism 4 of this second embodiment. The drawer rail 3 and the center rail 11 are still fully retracted into the carcass rail 2. Is based on Fig. 19 the furniture part pulled out of the furniture body, so the drawer rail 3 and the center rail 11 are pulled out together against the retraction 6 from the carcass rail 2. In this case, as long as in the first operating state, the claw 21 of the tilting slide 5 engages in the contact element 23, first, as described in the first embodiment, the catch spring 15 of the retraction mechanism 4 stretched. Join now according to wide pulling out of drawer rail 3 and middle rail 11, the front pin 43 of the tilt slide 5 in the angled or bent end portions 17 of the guideways 18, the tilt slide 5 is tilted or pivoted, whereby he releases the contact element 23 and the second operating state of the retraction mechanism 4 of this embodiment is achieved. In this, the tilting slide 5 is locked on the engagement of the pin 43 in the angled ends 17 of the guideways 18 in a waiting position. The drawer rail 3 and the middle rail 11, after the contact element 23 is released, are further pulled out against the pull-in direction 6 from the carcass rail 2. This second operating state is in Fig. 20 shown. The FIGS. 21 and 22 show the fully extended state of the drawer rail 3 and the center rail 11. It is also good to see how the tilt slide 5 remains in its waiting position and pulled out of the additional slot 12 of the center rail 11.

Now, the drawer rail 3 and the middle rail 11 in the direction of insertion 6 again inserted correspondingly far into the carcass rail 12, it comes to Kollison of the contact element 23 with the tilt slide 5, which in turn is pivoted so that the pin 43 from the angled or bent end portions 17 are swung out. As soon as this is done, the tilting slide pulls 5 with his claw 21 by means of the tensioned catch spring 15, the drawer rail 3 and the center rail 11 back into the in Fig. 19 shown position in which the furniture part is completely inserted or retracted into the furniture body.

The slot 7 through which the tilting slide 5 extends, is arranged in the second embodiment as in the first embodiment in the vertically extending wall portion 8 of the carcass rail 2.
