Description

The invention relates to a Deckenausziehführung for a pull-out of a furniture carcass part, with a guide rail, which is connectable to an inside of the ceiling of the furniture body directly or via a fixable on the inside of the ceiling carcass rail from which the guide rail is extendable, and with an opposite to the guide rail in an extraction pull-out and retractable against the pull-pull-out, wherein the extension of the pull-out of the guide rail is limited by a stopper held on the Ausziehschiene stop unit, which has a stopper portion to limit the extraction of the pull-out of the guide rail cooperates a counter-stop of the guide rail, and wherein the stop portion of the stop unit for adjustment between a locking position, in which it cooperates with the counter-stop and the extraction of the pull-out of the guide rail limited, and a passage position in which the counter-stop can be guided past the stop portion, about a pivot axis is pivotable.

Ceiling pull-out guides for pull-out cabinet parts, in particular overhead cabinet parts, serve to keep the pull-out cabinet part in an upright position and can therefore also be referred to as side guides. These Deckenausziehführungen often include three mutually displaceable rails to allow at least a full extension of the pull-out cabinet part, wherein the pull-out guide can be formed telescopically or with differential run of the middle pull-out rail.

To accommodate the weight of the pull-out cabinet part is a set on the bottom of the furniture body pull-out. Although such a pull-out guide is equipped with a stop that limits the extension, it is useful, too to provide a stop device at the top arranged Deckenausziehführung that limits the extension.

From the AT 3 164 U and AT 8 952 U Deckenausziehführungen are known, which have stop units to limit the extraction. When mounting the cabinet, the pull-out rail of the pull-out cabinet section is inserted into the guide rail, which is already connected to the ceiling inside. As a result, the stopper portion of the stopper unit must be manually brought to the lock position to take effect. In the AT 8 952 U here several locking positions are available to adjust the position in the Ausziehweg at which the stopper portion is effective (in order to achieve a vote with the stop of the determined at the bottom of the furniture body pull-out). If this manual operation of the stopper section is forgotten, the stopper unit will not take effect.

From the DE 20 2005 001 998 U1 is a Deckenausziehführung of the aforementioned type, in which an automatic adjustment of the stop portion of the stop unit is provided by a passage position in a blocking position. For this purpose, the abutment portion having stopper unit is designed as pivotable against the force of a spring element lever. When the pull-out rail is inserted into the guide rail during assembly of the ceiling pull-out guide, the lever is pivoted by the guide rollers rotatably mounted on the guide rail, respectively, so that the stopper section reaches the pass-through position in which the respective guide roller passes the stopper section can be. After passing a respective guide roller, the lever is swung back by the spring in the blocking position. When viewed in the pull-out direction furthest behind the guide roller of the guide rail forms when pulling the pull-out the counter-stop, which abuts against the stop portion of the located in the blocking position lever. A disadvantage of this known Deckenausziehführung It is, inter alia, that an adjustment of the stop position when pulling the pull-out rail is not possible.

The object of the invention is to provide an improved Deckenausziehführung of the type mentioned. According to the invention, this is achieved by a Deckenausziehführung with the features of claim 1.

In the Deckenausziehführung according to the invention, the pivot axis about which the abutment portion of the stop unit is pivotable relative to the pull-out displaced, preferably guided by the pull-out rail slidably. In this case, a plurality of blocking positions of the stop section are provided, in which the pivot axis of the stop section and thus the stop section lie at different positions of the longitudinal extent of the pull-out rail lying parallel to the pull-out direction. In the various blocking positions of the stop section, the pull-out rail can be extended to different extents from the guide rail. In a respective blocking position, the stop section is secured against displacement in the longitudinal direction of the pull-out rail, preferably by at least one engagement element of the stop section, which engages with at least one latching element of the pull-out rail. For adjustment between the different locking positions of the stop portion, the at least one engagement element of the stop portion is conveniently brought out of engagement with the at least one locking element by pivoting the stop portion about the pivot axis, in the same pivoting direction as in the pivoting from the locking position to the passage position.

In a Deckenausziehführung invention, the position of the end stop when pulling the pull-out rail can be adjusted from the guide rail in a simple manner.

An inventive design can advantageously also allow a very simple installation of the stop unit in the guide rail.

When mounting the Deckenausziehführung, when the first of the guide rail separate pull-out rail is inserted into the guide rail, the stop portion is moved from starting at the stop portion counter-stop of the guide rail, starting from the blocking position or one of the blocking positions in the passage position, wherein a pivoting of the stop portion to the Swivel axis takes place. This adjustment of the stop portion can in this case be carried out by the foremost locking position relative to the withdrawal direction, wherein the adjustment is preferably effected only by a pivoting of the abutment portion about the pivot axis, or starting from a different locking position, wherein the adjustment is a displacement of the pivot axis and a pivoting encompassed about the pivot axis.

After passing the counter-stop on the stop unit, the return of the stop section located in the passage position advantageously takes place automatically in the foremost locking position relative to the pull-out direction. For this purpose, the stop unit has at least one resilient element, of which the stop section located in the passage position is adjusted in the foremost locking position relative to the withdrawal direction, wherein the stop section is pivoted about the pivot axis. When adjusting the stop portion of one of the blocking positions in the passage position then the pivoting about the pivot axis takes place against the restoring force of this at least one resilient element.

To form such a resilient element, the stop unit may for example have a projecting from the abutment portion, supported on the pull-out arm, wherein the arm is elastically bendable and / or attached to an elastically bendable part of the stop unit and / or pivotable against a separate resilient element is connected to the stopper portion.

In an advantageous embodiment, the guide rail has guide rollers which are rotatably mounted about vertical axes and which engage between vertical webs of the pull-out rail. The counter-stop can be formed by the guide roller of the guide rail located furthest in the direction of the pull-out direction, or a counter-stop which is separate from the guide rollers can be mounted on the guide rail. If, during assembly, the guide rollers which lie in front of the counter-stop with respect to the pull-out direction start from the stop section of the stop unit, then these each pivot the stop section until the stop section assumes a position in which the respective guide roller can be guided past the stop section (this position can be identical to the passage position or the pivoting about the pivot axis may be less far or further as in the passage position).

To form the displaceable guide of the pivot axis of the stop section, the pull-out rail advantageously has at least one guide track, which is formed in particular by a slot. Preferably, guideways are present, which are formed by oblong holes, which are formed in opposite vertical webs of the pull-out, between which lies the stop unit. In the slots engage the journal of the stopper portion, which form the pivot axis.

The latching elements of the pull-out rail are preferably formed by protrusions of a longitudinal edge extending parallel to the pull-out direction of at least one slot which is formed in at least one of the vertical webs and into which at least one pin-shaped engagement element of the stop section protrudes.

The pivoting of the abutment portion about the pivot axis in a direction of rotation, in which pivots the stopper portion in its adjustment from the passage position to the foremost locking position, is advantageously of a Swivel stop surface limited, which has the engagement element and which starts at a ausziehschienenfeste counter-stop surface. It would also be conceivable and possible that a pivot stop surface directed in this direction of rotation is not formed on the engagement element or on one of the engagement elements but on a separate part of the stop unit.

The pivot axis of the stop portion is preferably guided displaceably parallel to the withdrawal direction of the pull-out rail.

An embodiment of a cabinet, especially upright, in which a Deckenausziehführung 1 invention is used, is in Fig. 1 shown. The pull-out cabinet part 2, especially the tall cupboard part, has a pull-out frame. Trays or compartments can be attached to this pull-out frame. As an example, in Fig. 1 a basket 3 attached to the pull-out frame is shown. Am based on the pull-4 front end of the Ausziehrahmens a panel 5 is attached.

At the bottom 6 of the furniture body 7, a lower pull-8 is fixed, which carries the pull-out cabinet part 2. A lower horizontal frame leg of the Ausziehrahmens is supported by an extendable rail 10 of the pull-8. The lower horizontal frame leg could also directly form an extendable rail of the lower pull-out guide. Between a fixed to the bottom 6 fixed rail 11 and the extendable rail 10 is preferably a central rail 12 is provided to allow at least a full extension of the pull-out cabinet part, i. in relation to the pull-out 4 rear end of the pull-out cabinet part 2, which is formed by the vertical frame legs 14, is in the fully extended state relative to the pull-4 front end of the furniture body 7 or in front of this. The lower pull-out guide 8 may be formed in a conventional manner.

To guide the upper end of the pull-out cabinet part 2 is the Deckenausziehführung 1. From this, the upper end of the pull-out cabinet part 2 is supported against tilting at right angles to the pull-4.

The Deckenausziehführung 1 according to the embodiment shown in the figures comprises a mounted on the inside of the ceiling 15 of the furniture body 7 carcass rail 16, a displaceably guided by this guide rail 17 and a displaceably guided by the guide rail 17 extending rail 18th

For displaceable guidance of the guide rail 17 relative to the carcass rail 16, for example, in a cage 20 rotatably mounted, between the rails 16, 17 arranged rolling elements 19, in particular balls, be provided, see. Fig. 6 , The displacement of the guide rail 17 relative to the carcass rail 16 is limited by stops.

If no full extension of the pull-out cabinet part 2 should be desired, the carcass rail 16 could also be omitted and the guide rail 17 could be designed for mounting on the ceiling inside. But it is preferred that the Deckenausziehführung 1 has three mutually displaceable rails 16, 17 and 18.

The guide rail 17 has two longitudinally spaced guide rails 17 spaced from each other about vertical axes rotatably mounted guide rollers 21. For example, for this purpose, as shown on a horizontal web 22 of the guide rail 17 axle journals 23 are mounted, projecting from the web 22 down and rotatably support the guide rollers 21 at their free ends.

There could also be more or fewer guide rollers 21. In addition to the guide rollers 21 or instead of these also slide bearing parts for lateral guidance of the pull-out rail 18 relative to the guide rail 17 may be present.

Relative to the pull-out direction 4 behind the guide rollers 21, the guide rail 17 has a counter-stop 24, which cooperates with the stop unit 18, described below, of the pull-out rail 18. The counter-stop 24 is here as formed on the web 22 and formed by this downward projecting body. From the counter-stop 24, a sliding guide function for lateral guidance of the pull-18 can be taken over the carcass rail.

To damp the impact of the counter-stop 24 at the end of Ausziehweges the pull-18, the counter-stop on (relative to the pull-4) rear end with a resilient portion 24a is formed. This is exposed to the rest of the body of the counter-attack 24 by extending over most of the height of the counter-attack slots.

The counter-stop 24 could also be formed by a guide roller 21 rotatably mounted about a vertical axis. This could be present, for example, in addition to the two further in the pull-out direction guide rollers 21.

The pull-out rail 18 has in the horizontal, perpendicular to the direction of withdrawal 4 stationary direction (= transverse direction) spaced-apart vertical webs 25, 26, between which a gap 27 is located. In this grip the guide rollers 21 and the counter-stop 24 in the assembled state of the ceiling extension guide 1 a.

The vertical webs 25, 26 are from a connecting this base web 28 upwards. For example, the base web 28 is aligned horizontally. In the embodiment shown, the pull-out rail 18 has an overall U-shaped cross-section.

When in Fig. 1 shown pull-out cabinet part 2 connects the pull-out 18, the vertical frame legs 13, 14 of the pull-out cabinet part 2 at their upper ends, wherein the vertical frame legs 13, 14 are connected at their lower ends by the horizontal frame leg 9. The pull-out rail 18 thus constitutes an integral part of the pull-out frame of the pull-out cabinet part 2, forming an upper horizontal frame leg of the pull-out frame. The pull-out rail 18 could also be a separate from the pull-out cabinet part 2 part, which is connected thereto.

On the pull-out rail 18, a stop unit 29 is mounted, which is located in the intermediate space 27 between the vertical webs 25, 26. The stop unit 29 includes a stopper portion 29a. At a stop surface 29b of the stop portion 29a runs when pulling the pull-18 at the end of Ausziehweges the counter-stop 24 at.

In the exemplary embodiment, the abutment surface 29b has first and second partial surfaces, which are located on first and second sections of the stopper portion 29a, which are spaced apart in a horizontal, perpendicular to the withdrawal direction 4 direction.

The stop unit 29 further has an arm 29c, which extends from the abutment portion 29a and extending from the abutment portion 29a at least partially obliquely to the withdrawal direction down and is supported in the region of its free end on the base web 28. The arm 29c, or at least one portion thereof adjoining the free end of the arm 29c, is of the position which it occupies without acting external forces (see eg Fig. 3, 4 and 5 ), against a resilient restoring force in the direction of an approach of the arm 29c to the abutment portion 29a bendable. In this case, the bending can take place within the extension of the arm 29c and / or in the region of the connection with the abutment portion 29a. This bending is, for example, from the comparison of 8 and 9 seen.

The arm 29c in the embodiment has first and second portions connected to the first and second portions of the stopper portion 29a and connected at their free ends by a connecting portion. The arm 29c thus has an overall U-shaped configuration.

The two sections of the stopper portion 29 are thus connected to each other in the embodiment via the arm 29c.

The vertical webs 25, 26 each have a guideway 30, which is formed by a parallel to the withdrawal direction 4 extending slot. In the guideways 30 engage journals 31 of the stop portion 29a, which form a pivot axis 32 for the stop portion 29a.

The two vertical webs 25, 26 further each have a recess 33 into which in each case two engagement elements 34, 35 protrude, which are formed by the abutment portion 29 a on both sides projecting pins.

The slot-shaped recesses 33 each have a first section 33a extending parallel to the withdrawal direction 4 and a second section 33b extending from the front end of the first section 33a and curved.

The upper longitudinal edge of the first portion 33a each has a series of protrusions. Between the individual bulges are tooth-like projections. The bulges form latching elements 36, in which the engagement elements 34, 35 can engage. A respective engagement element 34, 35 can in this case engage in different of the latching elements 36, whereby different blocking positions of the stopper portion 29a are defined, in which the abutment surface 29b of the abutment portion 29a is positioned at different locations along the longitudinal extent of the pull-out rail 18. If the engagement elements 34, 35 engage in latching elements 36, then the stopper portion 29a and thus the stop surface 29 b locked against a directed against the pull-4 direction shift.

Fig. 12 shows the foremost locking position relative to the withdrawal direction 4. If, starting from this foremost blocking position, the abutment portion 29a is pivoted about the pivot axis 32 so that the abutment surface 29b moves downwards, the engagement elements 34, 35 enter the second portion 33b of the respective recess 33 and the abutment portion 29a becomes in its passage position pivoted, cf. eg Fig. 13 , In this passage position, the stop surface 29 b lies below the counter stop 24, so that the stop unit 29 can be guided past the counter stop 24. Fig. 14 shows the largely passed position of the stop unit.

In the passage position, the spring-elastic element formed by the arm 29c and / or the elastic connection of the arm 29c with the abutment portion 29a is stretched. If the abutment portion 29a is released in the passage position, then the resilient element pivots the abutment portion 29a back into the foremost blocking position, cf. Fig. 15 ,

The adjustment of the stopper portion 29a in the passage position takes place during assembly of the ceiling extension guide, when the pull-out rail is inserted into the guide rail 17 against the pull-out to assemble these rails, by the leading to the stopper portion 29a guide rollers 21 (which may be replaced by other guide parts ) and the counter stop 24 which starts at the abutment portion 29a Fig. 7 to 16 shown.

Fig. 7 shows the still separated from the guide rail 17 pull-out 18. The pull-out rail 18 is pushed in the direction of arrow 46 (ie against the pull-4) on the guide rail 17. Fig. 8 shows the position in which with respect to the pull-out direction 4 foremost guide roller 21 to the abutment portion 29a starts, namely on a stop surface 29b opposite side of the stopper portion 29a, which forms a contact surface 29d. This contact surface 29d is arranged obliquely in the exemplary embodiment to the withdrawal direction 4. A course perpendicular to the withdrawal 4 but would also be possible.

Fig. 9 shows just the position in which the stop portion 29a has reached the passage position. Starting from this position, the foremost guide roller 21 a can be guided past the stop portion 29 a at this, as seen from Fig. 10 is apparent. As soon as the guide roller 21 a has passed the abutment portion 29 a, the abutment portion 29 a is pivoted back into the foremost blocking position with respect to the pull-out direction 4 by the arm 29 c supported on the base web 28 and the previously described elastic training.

This process is repeated in an analogous manner in the next following guide roller 21 and the counter-stop 24. For the counter-stop 24 this is in the Fig. 12 to 15 shown again. Fig. 12 shows the tarnishing of the counter-stop 24 against the contact surface 29d. Fig. 13 shows the achievement of the passage position of the stop portion 29a, whereupon the counter-stop 24 above the stopper portion 29a can be moved past this, see. Fig. 14. Fig. 15 and Fig. 16 show the position at which the counter-stop 24 has just completely overrun the stop portion 29a and the stop portion 29a has again assumed its blocking position.

Starting from the in the Fig. 15 and Fig. 16 illustrated position, the pull-out rail 18 can be inserted against the pull-out 4 until it reaches the fully inserted state, the fully inserted state is limited by a stop. If the pull-out rail is pulled out again in the pull-out direction 4, the pull-out at the point at which the counter-stop 24 starts against the stop face 29b of the stop section 29a is limited.

If the pull-out rail 18 in turn is to be separated from the guide rail 17, then the stopper portion 29a can be manually adjusted to its passage position, wherein the user pivots the stopper portion 29a about the pivot axis 32 in the passage position. The pivoting can be done by exerting a force acting on the base web 28 compressive force on the stopper portion 29 a. The at least one resilient element of the stop unit 29 is hereby tensioned. Starting from this in Fig. 17 illustrated position, the counter-stop 24 and the guide rollers 21 and / or the other or other guide elements can be moved past the stop portion 29a until the rails are separated from each other, see. Fig. 18 ,

The Fig. 19 to 22nd show the adjustment between two blocking positions, ie the change in the position at which the pull-out rail 18 abuts the counter-stop 24 of the guide rail 17 at the end of Ausziehweges. For this purpose, the abutment portion is pivoted about the pivot axis 32, so that the engagement elements 34, 35 are disengaged from the latching elements 36. The direction of rotation is the same as in the case of pivoting into the passage position. Such a limited pivoting is made possible by a corresponding formation of the width of the first sections 33a of the recesses 33. This condition is in Fig. 20 shown, wherein the direction of pivoting is indicated by the arrow 46. Here again a tension of the at least one elastic element of the stop unit takes place.

As a result, the desired longitudinal adjustment of the stop unit 29 can be carried out, whereby the stop section 29a shifts in the longitudinal direction of the pull-out rail 18 or the pivot axis 32a in the guide track 30. In Fig. 21 is starting from Fig. 20 a displacement against the withdrawal direction 4 is shown, which is indicated by the arrow 37.

As a result, the abutment portion 29 a is released, so that the resilient biasing force pivots the abutment portion 29 a about the pivot axis 32 back and the engagement elements 34, 35 brings into engagement with the latching elements 34 located above them. This is in Fig. 22 shown. The return pivoting is indicated by the arrow 38.

A displacement of engaging in the locking elements 36 engaging elements 34, 35 against the withdrawal direction 4 is blocked by the locking elements 36 (the locking elements 36 have perpendicular to the withdrawal direction 4 stationary surface portions which cooperate with the engagement elements 34, 35). A displacement of the engagement elements 34, 35 of the locking elements 36, in which the engagement elements 34, 35 engage in the pull-4 but is possible because the front relative to the withdrawal direction surfaces of the locking elements 36 are obliquely to the withdrawal direction 4.

Even if in the separated state of the pull-18 and guide rail 17 of the stop portion 29a occupies a blocking position, which is behind the foremost locking position, thus the rails analogous to Fig. 7 to 16 are pushed into each other, wherein the foremost guide roller 21, the stopper portion 29 a first along the first portions 33 a of the recesses 33 shifts and then pivoted into the passage position.

In the respective blocking position, a biasing force is exerted by the at least one resilient element of the stop unit 29, by means of which the at least one engagement element 34, 35 is held in engagement with the respective detent element 36.

In the embodiment shown, two engagement elements 34, 35 are located on each side of the abutment portion 29a. The holding force in abutment of the abutment stop 24 against the abutment portion 29a at the end of the withdrawal path is thereby increased relative to a single engagement element on each side of the stopper portion 29a. But if a sufficiently high holding power with a single Engagement element can be achieved on each side of the stopper portion 29a, so such a configuration can be selected.

Due to the design of the stop unit according to the illustrated embodiment, the stop unit can be mounted in a simple manner in the pull-out rail 18. For this purpose, the transversely spaced apart portions of the stopper portion 29a are compressed against the resilient design of the stopper unit 29 until the stub axles 31 in the guideways 30 and the engagement members 34, 35 can be inserted into the recesses 33.

If the assembly is carried out in other ways, for example by the vertical webs 25, 26 are pressed apart or the elongated holes forming the guideways 30 and recesses 33 are continued to the rear end of the pull-out, so the stopper portion 29 a also over its width (in the horizontal direction perpendicular to the withdrawal direction 4) be formed continuously. In the side view this can be in Fig. 5 represented form.

For actuating the abutment portion 29a, the peg-shaped engagement elements 34 and / or 35 could also be designed to be elongated, for example, so that an actuation could take place at the ends of the engagement elements 34 and / or 35 protruding from the oblong holes.

The FIGS. 23 to 27 show a further possible training for the actuation of the stop unit 29. It is here an additional operating part 39 is provided. This comprises first and second side walls 40, 41, which are interconnected by a connecting web 42. In a frontal view ( Fig. 27 ), the actuating member 39 thus has a U-shape.

The actuating part 39 is attached from below onto the pull-out rail 18, so that the vertical webs 25, 26 of the pull-out rail 18 lie between the side walls 40, 41 of the actuating part 39. In this case, the side walls 40, 41 further each have a recess 43, into which protrudes the protruding from the respective slot end of the respective engagement member 35. By a resilient design of the actuating part 39, the side walls 40, 41 can be snapped with the recesses 43 on the engagement elements 35.

For the engagement elements 34, depressions 44 are provided in the side cheeks 40, 41 into which the ends of the engagement elements 34 protrude, the depressions 44 having a larger dimension than the cross section of the engagement element 34 to provide clearance for movement of the respective engagement element 34 ,

In the area of the front ends of the side cheeks 40, 41 relative to the pull-out direction 4, these each have an inwardly projecting projection 45, which rests on the upper edge of the respective vertical web 25, 26 in the state of the operating part 39 placed on the guide rail 17. The projections 45 engaging over the vertical webs 25, 26 form pivot points for the actuating part 39. The horizontal axis formed by these projections 45 can be pivoted downwards relative to the pull-out direction 4 at the rear end of the actuating part 39. Here it takes the engagement elements 34 and thus the stopper portion 29 a with.

In order to adjust the stop position of the pull-out rail 18, the actuating part 39 is thus pivoted downwards with its rear end, with a corresponding pivoting of the stop section 29a about the pivot axis 32. As a result, the operating member 39 is displaced along the pull-out rail 18 (parallel to the pull-out direction 4) until the desired stop position is reached, with the engagement members 34, 35 sliding along the first portions 33a of the recesses 33. Then the operating part 39 is released, wherein by the at least one resilient element of the stop unit 29, a return pivoting of the stop portion 29a and thus of the operating part 39 takes place. The engagement elements 34, 35 thus again come into engagement with the latching elements 36.

By means of the actuating part 39, the abutment portion 29a can furthermore be pivoted into its passage position. After the engaging elements 34, 35 of the abutment portion 29a have possibly been displaced forward along the first portions 33a of the recesses 33, the actuating part 39 is pivoted about the axis formed by the projections 45 (whereby also a small displacement in the longitudinal direction of the pull-out rail 18 takes place) , It can be effected by one of its blocking positions in its passage position, the already described adjustment of the stop portion 29a.

When the stop section 29a is displaced from the locking position to the passage position upon insertion of the pull-out rail 18 into the guide rail 17, the actuating part 39 is thereby pivoted by the movement of the stopper section 29a therefrom around the horizontal axis formed by the projections 45 and in the longitudinal direction the pull-out rail 18 is moved.

In this way, a simple operation of the stop unit 29 can be achieved. Furthermore punch outs of the pull-out rail can be covered by the operating part 39. The operation of the operating part 39 can be illustrated by a label attached thereto.

Instead of the engagement elements 35 and the engagement elements 34 could be used for coupling with the actuating member 39, so be accommodated in the recesses 44 without major play and the recesses 43 may be formed enlarged to form a free space for the movement of the ends of the engagement elements 35.

Various modifications of the stop unit 29 shown in the figures are possible. For example, the arm 29c does not have to go out from the rear end of the stopper portion 29a. It would also be possible, for example, to provide an arm 29c mounted pivotably about an axis on the abutment portion 29a, which arm is acted upon by a separate spring element against the base web 28.

Instead of the sliding guide of the pivot axis 32 by a kind of slotted guide, engage in the axle journal in slots, in principle, other types of guides for sliding guide the pivot axis 32 relative to the pull-18 may be used. For example, the pivot axis 32 could be fixed to at least one bearing part which is slidably guided with respect to the pull-out rail 18, e.g. in the manner of a dovetail guide.

It is also conceivable and possible for the pivot axis of the stop section to be displaceably guided by a part of the stop unit, which is connected to the pull-out rail.

In the illustrated embodiment, the stop surface 29b is pivoted away during the pivoting of the stop portion 29a from the blocking position to the release position. Instead, a pivoting upward would be conceivable and possible, the counter-stop 24 and the guide rollers 21 and / or other guide elements would have to project from the web 22 upwards and these parts would pass in the passage position of the stop portion 29a below the stopper portion 29a at this. The provision of the passage position in the blocking position could be done in this case (also) by the weight of the stop unit 29, with an additional spring-elastic element, which causes the provision, could also be omitted.

The locking elements 36 could also be formed in a different form. For example, locking elements could also be provided which are separate from the stop surfaces are formed, which limit the pivoting of the stopper portion 29a in a pivoting direction, which is opposite to the pivoting direction during the pivoting into the passage position.
