The body rail is fixed at the inner side of the cover. A pulled-out rail (18) is provided with a guide track (30,31) that stands partially obliquely to a pulled-out direction (4). A stop portion (29a) of a stop unit (29) is guided for adjustment between a locking position and the passing position along the guide track.

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 between at least one locking position in which he cooperates with the counter-stop and the extraction of the pull-out rail from the guide rail Enzt and a passage position is adjustable, in which the counter-stop on the stop section is guided past.

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 Ceiling pullouts are known, which have stopper units for limiting 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 in this case, several blocking positions are available to adjust the point 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 pull-out rail at least one at least partially obliquely to the withdrawal direction guide track. Along this guideway is the stop portion of the stop unit between at least one locking position, which can take the stopper portion and the passage position of the stopper portion slidably guided.

Due to the construction according to the invention, a very simple mounting of the stop unit in the guide rail can be made possible.

In addition, an automatic reset of the adjusted in the passage position stop portion can be made possible in the locked position or one of the blocking positions. For this purpose, a spring-elastic element is preferably provided, from which the stop section located in its passage position can be displaced into its blocking position or one of its blocking positions.

For example, one arm of the stop unit can be supported on the pull-out rail, wherein the arm is elastically bendable and / or attached to an elastically bendable part of the stop unit and / or is pivotally connected to another part of the stop unit against a separate spring-elastic element.

When mounting the Deckenausziehführung when the pull-out rail is inserted into the guide rail, the stopper portion is favorably against the Force of the at least one spring element from the start of the abutment portion, mounted on the guide rail counter-stop in the passage position moved until the counter-stop can be passed on the stop portion of the stop unit.

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 in relation to the pull-out direction start from the stop section of the stop unit located in its blocking position or one of its blocking positions, these respectively displace the stop section along the at least one guide track until the stop section assumes a position the respective guide roller can be guided past the stop section (this position can be identical to the passage position or the displacement along the at least one guide track can be less far or further as in the shift to the passage position).

In order to limit or prevent a pivoting of the abutment portion about a horizontal axis perpendicular to the withdrawal direction during the displacement of the abutment portion from its blocking position to its passage position and vice versa, the abutment portion preferably has at least two guide elements lying at different heights, which in the at least a guideway are guided displaceably, wherein the lying at different heights guide elements are preferably guided in separate guideways. In another possible embodiment, a limitation or blocking of a pivoting of the abutment portion about a horizontal axis could also by a such pivoting limiting or blocking engagement between the at least one guide element and the guideway are achieved, in which engages this.

In a preferred embodiment of the invention, at least one guideway in addition to the obliquely to the withdrawal direction section on a parallel to the withdrawal direction section. In this case, at least one of the sections lying parallel to the direction of withdrawal advantageously has a plurality of latching elements with which at least one guide element guided in this guide track can be selectively brought into engagement. By the at least one guide element is brought into engagement with the desired locking element, it can be adjusted at which point of the Ausziehweges the counter-stop starts against the stop portion of the stop unit.

Conveniently, a kind of slotted guide is provided for the displaceable guidance of the stop portion of the stop unit from the blocking position into the passage position. For this purpose, the guideways are preferably formed by oblong holes which are formed in opposite vertical webs of the pull-out rail, between which the stop unit lies. Into the slots forming the guideways engage pins arranged on the stop unit. Here, the stopper portion has at least two opposite, engaging in slots of the vertical webs of the pull-out pin.

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 an extendable Form the 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, ie the relation to the pull-4 rear end of the pull-out cabinet part 2, which from the vertical frame legs 14 is formed, in the fully extended state in relation to the pull-4 front end of the furniture body 7 or before 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 may be provided 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 designed as a web 22 and formed by this downwardly 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 vertical webs 25, 26 spaced apart from one another in the horizontal direction at right angles to the pull-out direction 4 (= transverse direction) on, 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 rail 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 legs 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. A respective section of the abutment section 29a has an upwardly extending section 29f, at its edge pointing in the direction of withdrawal 4 the respective surface of the abutment surface 29b is located, and from the lower end of this upwardly extending portion 29f outgoing, in the pull-4 extending section 29g.

The stop unit 29 further has an arm 29c, which extends from the abutment portion 29a (in the illustrated embodiment from the front end of the portion 29g) and extending from the abutment portion 29a obliquely opposite the pull-out direction and 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 movable from the position which it assumes without external forces acting (cf. Fig. 3, 4 and 5 ), against a resilient restoring force in the direction of an approach of the free end of the arm 29c to the stop 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 section 29a and / or within the section 29g of the abutment section 29a extending in the withdrawal direction. 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.

At the rear end (relative to the pull-out direction 4), the stopper portion 29a has at least one extension 29d projecting counter to the pull-out direction 4, on which actuation of the stopper portion 29a can be performed, as described below. In the embodiment, each portion of the stopper portion 29a is provided with such a projecting projection 29d.

The vertical webs 25, 26 each have first and second guide tracks 30, 31, which are formed by oblong holes and for displaceable guidance of the stop portion 29a of the stop unit 29 serve. For this purpose, the abutment portion 29a has first guide elements 32, 32 'guided by the first guide tracks 30, which are respectively arranged on opposite sides of the abutment portion 29a, and second guide elements 33 guided by the second guide tracks 31, which are arranged on opposite sides of the abutment portion 29a are. The guide elements 32, 32 ', 33 are each formed by pins which engage in the respective slot.

The first and second guide tracks 30, 31 each have an obliquely to the withdrawal direction 4 stationary portion 30 a, 31 a, wherein these sections 30 a, 31 a parallel to each other. The angle to the withdrawal direction 4 is favorably in the range of 20 ° to 50 °, for example at 30 °. At the rear ends of these obliquely extending sections 30a, 31a relative to the pull-out direction 4, the guide tracks 30, 31 each have a horizontal section 30b, 31b extending parallel to the pull-out direction 4. The horizontal portions 30b of the first guideways 30 in this case each have a plurality of latching elements 34, which are formed by protrusions on the upper longitudinal edges of the guideways 30 forming slots in these sections 30a, 31a.

The first guide elements 32, 32 'can engage in different locking elements 34, whereby different locking positions of the abutment portion 29a are defined, in which the abutment surface 29b of the abutment portion 29a is positioned at different locations along the length of the pull-out rail 18.

Fig. 12 shows the foremost locking position relative to the withdrawal direction 4. If, starting from this foremost blocking position, the first and second guide elements 32, 32 ', 33 are displaced over the obliquely downwardly extending sections 30a, 31a of the first and second guide tracks 30, 31 (for example by manual actuation on the extensions 29d), then reaches the stop portion 29a in its passage position, see. eg Fig. 13 , In this Durchlassstellung is the displacement of the stop portion 29a with the stop surface 29b below the counter-stop 24, so that the stop unit 29 can be moved past the counter-stop 24, see. eg Fig. 14 ,

In the passage position, the resilient element formed by the arm 29c or its connection with the stop section 29a or by the section of the stop section 29a extending in the direction of displacement is tensioned. If the abutment portion 29a is released in the passage position, the resilient element displaces the abutment portion 29a along the inclined portions 30a, 31a of the guideways 30, 31 back into the foremost locking position.

The displacement of the stopper portion 29a into the passage position occurs in the installation of the ceiling extension guide when the pull-out rail is inserted into the guide rail 17 against the pull-out direction to assemble these rails by the guide rollers 21 which come to the stopper portion 29a (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 the arrow 35 (ie opposite to the pull-4) on the guide rail 17. Fig. 8 shows the position in which the foremost guide roller 21 with respect to the pull-out direction 4 starts against the abutment portion 29a, namely on a side of the abutment portion 29a opposite the abutment surface 29b, which forms a displacement surface 29e. To facilitate the displacement of the stop portion 29a, this displacement surface 29e is arranged obliquely 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 displaced 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 spring-elastic design described above.

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 to the displacement surface 29e. Fig. 13 shows the achievement of the passage position of the stopper portion 29 a. Fig. 14 shows the passing of the counter-stop 24 above the stopper portion 29a. 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, then the pulling on the in the Fig. 15 and 16 shown point at which the counter-stop 24 starts against the stop surface 29b of the stopper portion 29a, limited.

If the pull-out rail 18 in turn to be separated from the guide rail 17, the stop portion 29a can be manually moved into its passage position by the user the stop portion 29a by actuation of the at least one extension 29d along the inclined portions of the guideways 30a, 31 a is moved , Starting from this in Fig. 17 shown Position, the counter-stop 24 and the guide rollers 21 and / or the other or other guide elements on the stopper portion 29 a can be moved past until the rails are separated from each other, see. Fig. 18 ,

The Fig. 19 to 22nd show the adjustment of the position at which the pull-out 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 horizontal axis formed by the second guide elements 33, so that the first guide elements 32, 32 'out of engagement with the latching elements 34. Such a limited pivoting is made possible by a corresponding formation of the width of the oblong holes in the horizontal sections 30b of the guideways 30. This condition is in Fig. 20 shown, wherein the direction of pivoting is indicated by the arrow 36. The pivoting can be done by exerting a force acting on the base web 28 compressive force on the abutment portion 29a, for example by attack on at least one extension 29d, wherein the free end of the arm 29c, which is supported on the base web 28, the stopper portion 29a approaches and in this case the resilient Element of the stop unit 29 is stretched in an analogous manner as above in connection with the adjustment of the blocking position in the passage position.

As a result, the desired longitudinal adjustment of the stop unit 29 can be carried out, with the first guide elements 32, 32 'in the horizontal sections 30b of the first guide track 30 and the second guide elements 33 in the horizontal sections 31b of the second guide tracks 31 move. 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 stopper portion 29a is released, so that the resilient biasing force pivots back the stopper portion 29a about the axis formed by the second guide members 33 and brings the first guide members 32, 32 'into engagement with the detent members 34 located above them.

This is in Fig. 22 shown. The return pivoting is indicated by the arrow 38.

A displacement of the engaging in the locking elements 34 first guide members 32, 32 'against the withdrawal direction 4 is blocked by the locking elements 34 (the locking elements 34 have perpendicular to the withdrawal direction 4 stationary surface portions which cooperate with the first guide members 32, 32'). A displacement of the first guide members 32, 32 'from the locking elements 34, in which the first guide members 32, 32' engage, in the pull-4, however, is possible because the relative to the pull-out front surfaces of the locking elements 34 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 one another, wherein the foremost guide roller 21 first moves the stopper portion 29a in the foremost locking position and from there 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 guide element 32, 32 'is held in engagement with the respective latching element 34.

In the exemplary embodiment shown, two first guide elements 32, 32 'are located on each side of the abutment portion 29a. The holding force in abutment of the counter-abutment 24 on the abutment portion 29a at the end of the Ausziehweges is thereby increased relative to a single first guide member on each side of the stopper portion 29a. However, if a sufficiently high holding force can be achieved with a single first guide element 32 on each side of the abutment portion 29a, then such a design 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 portions of the abutment portion 29a, which are spaced apart in the transverse direction, are compressed against the resilient design of the abutment unit 29 until the pins forming the guide elements 32, 32 ', 33 can be inserted into the elongated holes forming the guideways 30, 31.

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 first and second guideways 30, 31 continued to the rear end of the pull-out, the stopper portion 29 a can also over its width (in horizontal direction at right angles to the pull-out direction 4). In the side view this can be in Fig. 5 represented form.

The actuation of the stop unit 29 could also take place in a different way than by the extension 29d, so that this extension 29d could also be omitted. For example, the peg-shaped guide elements 32 and / or 32 'could be designed to be extended so that an actuation could take place at these ends of the guide elements 32 and / or 32' 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 between the side walls 40, 41 of the operating part 39 are located. In this case, the side cheeks 40, 41 further each have a recess 43 into which protrudes the protruding from the respective slot end of the respective first guide element 32 '. By a resilient design of the actuating part 39, the side walls 40, 41 can be snapped with the recesses 43 on the first guide elements 32 '.

For the first guide elements 32 recesses 44 are provided in the side walls 40, 41, into which the ends of the first guide elements 32 protrude, said ends of the first guide elements 32 are received with play in the recesses 43.

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 with it the first guide elements 32 'and thus the abutment portion 29a.

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, a corresponding pivoting of the stop section 29a taking place around the horizontal axis formed by the second guide elements 33. As a result, the operating member 39 is moved along the pull-out rail 18 (parallel to the pull-out direction 4) until the desired stop position is reached. Then, the actuating member 39 is released, wherein the spring elasticity of the stop unit 29, a return pivoting of the stop portion 29a and thus of the operating part 39 takes place. The first guide elements 32, 32 'thus again engage with the latching elements 34.

By means of the actuating part 39, the abutment portion 29a can furthermore be pivoted into its passage position. For this purpose, the actuating part 39 is correspondingly pivoted about the axis formed by the projections 45 and displaced along the pull-out rail 18. It can be effected by its already described movement of the stop portion 29 a from its blocking position into its passage position.

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 member 39 is pivoted by the movement of the stopper portion 29a corresponding to the horizontal axis formed by the projections 45 and in the longitudinal direction of the pull-out rail 18 postponed.

In this way, a slight actuation 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.

Various modifications of the stop unit 29 shown in the figures are possible. For example, the arm 29c does not have to extend from the front 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 stopper portion by a kind of slotted guide, engage in the guide pin in slots, in principle, other types of guides for sliding guide of the stopper portion 29a relative to the pull-18 may be used. For example, a guide could be provided in the manner of a dovetail guide, the at least one guide track on at least one of the vertical webs 25, 26, preferably on both vertical webs 25, 26 includes.

If only one adjustment between a single blocking position and the passage position is desired, ie without an adjustment of the stop position at the end of Ausziehweges pull-out 18, so the horizontally and parallel to the withdrawal direction 4 extending portions 30 b, 31 b of the first and second guideways and Locking elements 34 omitted. In this case, first and second guide elements lying at different heights of the stop section 29a could also be displaceably guided in a common, obliquely running guide track.

Characterized in that the stopper portion 29 a arranged at different heights first and second guide members 32, 32 'and 33, pivoting of the stop portion 29 a can be prevented or limited by a horizontal axis lying at right angles to the withdrawal 4 axis, namely in the training in Shape of a slotted guide through the widths of the guideways formed by the oblong holes. Blocking or limiting the pivoting of the abutment portion 29a on the other hand could also be effected by the guidance of at least one guide element in the guideway itself, for example by instead of round pins forming the guide elements, those with a greater extent in the direction of the guideways than in the direction perpendicular be used for this purpose.

In the embodiment shown, the guideways 30, 31 extend in the region of their obliquely extending portions 30 a, 31 a in the pull-4 viewed from top to bottom. Instead, a course from bottom to top would be conceivable and possible, wherein the counter-stop 24 and the guide rollers 21 and / or other guide elements would have to protrude from the web 22 upwards and these parts would pass in the passage position below the stop portion 29a at this. The provision from the passage position in the Sperrsteliung could in This case (also) by the weight of the stop unit 29, wherein an additional spring-elastic element, which causes the provision, could also be omitted.

Instead of the second guideways 31 and the second guide elements 33 or in addition to these, pins could also be arranged at the free end 29c of the arm, which protrude into guideways formed by oblong holes in the opposite vertical webs 25, 26. For example, these guideways could extend parallel to the withdrawal direction 4. The arm 29c would then be supported with its free end instead of the base web 28 on these guideways.

The locking elements 34 could also be formed in a different form, for example, could also be provided by the guideways 30, 31 separate locking elements with which engage engagement elements of the stop unit.
