Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a pull-out fitting with the features of the preamble of independent claim 1 and to a storage cabinet with such a pull-out fitting.

In particular, the present invention relates to a Ausziehbeschlag for a high storage cabinet, d. H. a so-called tall cabinet. The Ausziehbeschlag can also be provided, for example, for a base cabinet or any other cabinet.

A storage cabinet for which the pull-out fitting is provided comprises a body having an opening and a door which can be swiveled open relative to the body about a pivot axis extending in the edge region of the opening. In a closed position, the door closes the opening, and in an open position, the door at least substantially clears the opening.

A pull-out fitting is generally understood to mean a fitting with which a slide can be pulled out in order to be able to drive out the slide, object supports supported thereon, and any objects arranged on the object supports for better accessibility from the body of a supply cabinet.

STATE OF THE ART

A known Ausziehbeschlag for a storage cabinet with the features of the preamble of independent claim 1 is the product VSA the applicant, see http://www.vauth-sagel.de/de/moebel/03_produkteKueche/03_Hochschraenke/VSA.php. The s Product VSA has a frame-shaped slide on which trays are freely attachable as object trays and which is mounted on a first pull-out on the floor and a second pull-out on the ceiling of the body of the respective Ausziehschranks. In this case, the slide is mounted in each case on a movable part of the two Ausziehschienen, while a fixed part of the two Ausziehschienen is attached to the floor or the ceiling. A door catcher of the product VSA comprises two driver pedestals, which are attached to the top and bottom of the pivotable door of the storage cabinet and to each of which a Zugdruckarm is articulated. At their other ends, the two Zugdruckarme are articulated to the frame-shaped slide, on the opposite side of the pivot axis of the door Ausziehschienen. About the Zugdruckarme the pivotal movement of the door with a pull-out of the slide is bidirectionally coupled. That is, with the swinging of the door, the slide moves out with the attached object trays out of the body of the storage cabinet of the Ausziehschienen out, and when closing the door moves the slide with the attached object trays back into the pantry. In other words, each pivoting of the door results in a movement of the slide and vice versa. So if the slide with the object trays is pushed into the pantry, this also leads to a closing of the door.

The product VSA allows access to the objects arranged on the object trays both from the front and from the side opposite the door, at least as far as the object trays with the slide have moved out of the cabinet of the supply cabinet. When compared with their depth relatively wide storage cabinets the space and resulting in the lever and path ratios for the Türmitnehmer are relatively cheap. So it turns out to be difficult to move out the object trays when you swing the door by 90 ° or a little more to substantial proportions in front of the opening of the body of the storage cabinet. In comparison to their depth narrow storage cabinets, however, the driver pedestals must be mounted relatively close to the pivot axis of the respective door and lay so when swinging the door only a relatively short way around the pivot axis of the door. This route is not sufficient with the push-pull rod transferred to the slide, in order to drive out the object trays in substantial portions in front of the opening of the supply cabinet. The product VSA is therefore offered only for wider storage cabinets.

From the DE 10 2007 009 894 C5 is a corner cabinet with a cabinet body and an accessible via a between a closed position and an open position pivotally mounted on the cabinet body corner door accessible interior known. In the interior, at least one tray is pivotally mounted by means of a fitting between an inner position and an outer position in which the tray is at least partially beyond a plane of a door opening of the corner cupboard. A driver device is provided for the indirect or immediate movement coupling of corner cabinet door and tray, whereby the tray when you open the corner cabinet door by this mitnehmbar and can be swung out of the interior of the corner cabinet. An entrainment of the tray takes place into the open position of the corner cabinet door. Decoupling means for decoupling of corner cabinet door and tray comprise a bolt and a guide piece on which the bolt during the movement of the tray from the inner to the outer position to a certain intermediate position of the tray, which corresponds to the open position of the corner cabinet door, to transmit the movement of the Corner cabinet door attacks on the tray. By handling the tray, the bolt is automatically decoupled from the guide piece from the tray intermediate position. The guide piece has a slot-like bolt receptacle, from which the bolt is carried out in the Tablarbewegung in the outer position and in which the bolt retracts during the Tablarbewegung in the inner position. The entrainment device has a single lever, which is mounted in a pivot bearing pivotally mounted on the corner door. At the free end of the single lever, the bolt is provided. The guide piece is arranged on the underside of the tray.

The in the DE 10 2007 009 894 C5 revealed coupling of the movements of the corner cupboard door and tray is not a bidirectional coupling. This means that although the tray is swung out by pivoting the corner cabinet door from the interior of the corner cupboard and the corner cupboard door is closed by pivoting the tray into the interior. But it is not pivoting of the tray by closing the corner door possible because the coupling is given only in tensile, but not in the pressure direction. Thus, in order to avoid malfunctioning, the user is given a specific sequence of operation of the corner cabinet door and of the tray when opening and closing or swinging out and swinging in and out.

From the EP 2 353 439 A1 is a fitting for corner cabinets with a front door accessible via a corner door, known in plan essentially rectangular interior. The Fitting consists of at least one in the interior of the corner cabinet stationarily supported support for holding at least one one-piece tray of semi-circular basic shape. The carrier has at least one tray supporting and the tray on a predetermined trajectory from an inner position in the interior of the corner cabinet in a substantially located in front of the door opening of the corner cabinet outer handlebars articulating with the underside of the tray and a support bracket with a Corner cupboard part, in particular a side wall part, is pivotally connected. Between the door opening closing corner cabinet door and the tray is a driving device for coupling the corner cabinet door with the tray during at least part of the opening movement of the corner cabinet door provided. The driver device has a stationary mounted on the door driver, which is provided with a pivotally held driving pawl which is durable during an opening movement of the corner cabinet door in a coupling position with a coupling member of the tray. After at least partial opening of the corner cabinet door, the driving pawl can be decoupled from the coupling member of the tray in the course of a further outward movement of the tray by the driving pawl. After transferring the tray in an intermediate pivoting position and / or after transferring the tray in the closed position, the driving pawl can be coupled to the coupling member again. The driving pawl is supported under the action of a spring force on the driver and has a guideway for the coupling member of the tray.

Also in the case of the EP 2 353 439 A1 Known fitting is the coupling of the door with the tray during the part of the opening movement of the door is not bidirectional, ie not provided for re-pivoting of the tray by closing the door as well as for swinging out of the tray by opening the door.

From the WO 2012/159642 A1 is a fitting for corner cabinets with a front door accessible via a corner door, known in plan essentially rectangular interior. The fitting consists of at least one supportable in the interior of the corner cabinet support for holding at least one one-piece tray of semi-circular basic shape, wherein the carrier at least one tray and supporting the tray on a predetermined trajectory from an inner position in the interior of the corner cupboard in a substantially before Having the door opening of the corner cabinet located outside position guiding handlebar, which hinged to the bottom of the Tablars and a carrier fitting with a Eckschrankteil, in particular a side wall part, is pivotally connected. Between the door opening closing corner cabinet door and the tray is provided a driving device for coupling the corner cabinet door with the tray during at least part of the opening movement of the door. The entrainment device has a fixedly attached to the corner door door carrier with a guide slot into which a fixed to the tray, unlockable coupling member for entrainment between the corner cupboard door and tray is inserted and movable in this. The coupling member comprises a height-adjustable, insertable into the guide slot driver area and is automatically inserted from an unlocked position by a relative movement of the tray relative to the corner door in a driving position in the guide slot. Unlockable is the coupling member by a manually activated height change of the driver area.

In this known fitting is - as long as the driver engages in the guide slot - while basically given a bidirectional coupling between the corner cabinet door and the tray. Nevertheless, it proves to be difficult due to the course of the trajectory of the tray due to coupled to the door tray by closing the door in its interior position in the interior of the corner cupboard, so that here is a smooth function is only given when the tray through Opening the door brought out of its inner position and returned by direct attack on the tray in its inner position, at least as long as the opening angle of the door is close to 90 °. In addition, the use of this known fitting requires the manual decoupling of the tray from the door to maximally move the tray out of the interior of the corner cupboard.

From the DE 81 11 242 U1 is a cabinet with vertically arranged push frame known, which is mounted on its upper and lower sides in a parallel guide. In this case, the upper and the lower region of the frame are connected to each other by a cable guide or by a toggle linkage, which cause a synchronization of the paths two parallel guides when pulling the frame out of the cabinet.

From the DE 203 18 735 U1 a telescopic guide rail for furniture drawer is known, which can be fixed to a furniture body carcass rail, a drawer-side fixable drawer rail and at least one between the carcass rail and drawer rail arranged center rail comprises. The drawer rail is coupled to the center rail to its maximum or almost maximum displacement relative to the cabinet rail. For coupling the middle rail with the drawer rail, a driving lever pivotally connected to the driving lever is provided, which is movable by a mounted on the carcase guide means at maximum or almost maximally extended middle rail out of its coupling position. By coupling the drawer rail with the center rail ensures that when opening or pulling a furniture drawer out of the insertion position initially the middle rail relative to the carcass rail is moved to its maximum displacement until the drawer rail is released and compared to the center rail, which is now in its maximum Excerpt position is, can be moved. If the drawer is pushed back out of its completely pulled out of a furniture body state, resulting from the weight load and the resulting tension within the rail elements that initially moved the drawer rails relative to the center rails and then the center rails including the drawer rails back into their Be moved to the final position. A mechanical coupling between middle rails and drawer rails is thus not necessary when retracting a drawer.

OBJECT OF THE INVENTION

The invention has for its object to show a Ausziehbeschlag with the features of the preamble of independent claim 1 and a storage cabinet equipped therewith, which makes objects easily attached to the slide object trays even when compared with the cabinet depth cabinet width of the cupboard easily accessible.

SOLUTION

The object of the invention is achieved by a Ausziehschlag with the features of independent claim 1. The dependent claims 2 to 19 are directed to preferred embodiments of the Ausziehbeschlags invention. The independent claim 20 relates to a storage cabinet with a pull-out fitting according to the invention.

DESCRIPTION OF THE INVENTION

The invention provides a pull-out fitting for a storage cabinet with a body having an opening and with a relative to the body pivotable about a pivot axis extending in the edge region of the opening door ready. In this case, the Ausziehbeschlag comprises a pull-out with a movable part to which a slide is to be attached, and with a fixed part on which the movable part is movably mounted in a pull-out direction and to fasten the orientation of the pull-out direction on the opening in the body is. Furthermore, the pull-out fitting comprises a door catch with a catch base to be fastened to the door and with a pull-pressure arm articulated at both ends, which pivotally moves the catch base about the pivot axis with a first pull-out movement of the movable part of the pull-out rail in the pull-out direction between a retracted position and a first pull-out position extended position bi-directionally coupled. The Zugdruckarm is connected in series between the driver base and the movable part of the pull-out rail with an activatable freewheel, which is associated with an activation device. The activation device activates the freewheel when the movable part of the pull-out rail reaches its first extended position from its retracted position. The activated freewheel releases a second pull-out movement of the movable part of the pull-out rail independent of the pivotal movement of the driver pedestal about the pivot axis in the pull-out direction between the first extended position and a second extended position farther from the retracted position. The activation device blocks the freewheel again when the movable part of the pull-out rail reaches its first extended position from its second extended position.

In the Ausziehbeschlag invention, the bidirectional coupling between the rotational movement of the door and the first extension movement of the movable part of the pull-out rail is effected via the articulated at its two ends Zugdruckarm. In this case Zugdruckarm means that the Zugdruckarm can be loaded on both train and on pressure between its two ends and accordingly transmits both tensile and compressive forces between its two ends. The fact that the Zugdruckarm is articulated at its two ends, means that it is pivotally mounted in parallel to the pivot axis of the door extending pivot axes relative to the parts that connect to the Zugdruckarm in the direction of the driver base and the movable part of the pull-out rail. Apart from the freewheel connected in series with him Zugdruckarm be articulated directly to the driver base on the one hand and the movable part of the puller on the other hand. The movable part will be arranged with the rest of the pull-out rail usually in the longitudinal center plane of the storage cabinet. In order to realize favorable leverage ratios, however, it is advantageous to steer the Zugdruckarm further away from the axis of rotation of the door to the moving part of the pull-out rail. For this purpose, a special boom can be attached to the pull-out rail. Often, however, the slide which is attached to the pull-out rail is oriented transversely to the pull-out direction and correspondingly extending from the axis of rotation of the door across the pull-out rail. Then the Zugdruckarm on the side facing away from the axis of rotation of the door side of the pull-out rail can be pivotally connected to this frame to direct it to the moving part of the pull-out rail. In other words, the articulation of the Zugdruckarms to the moving part of the pull-out rail does not mean that it must be articulated directly to the moving part of the pull-out rail. Rather, the articulation is sufficient for a component which, at least over the first pull-out movement, moves with the movable part of the pull-out rail in the pull-out direction.

When the door of a supply cabinet equipped with the pull-out fitting according to the invention is swung open, the movable part of the pull-out rail, with the slide mounted thereon, moves forward in the pull-out direction toward and through the opening of the carcass. This coupled movement of the door and the movable part of the pull-out rail continues until the door is swung open. In this case, the movable part of the pull-out rail reaches its first extended position, and with its reaching the activation device activates the freewheel. By taking advantage of this freewheel for the moving part of the pull-out against the door, which thus allows a second pull-out in the pull-out, without the door moves on, attached to the moving part of the pull-out slide or it can be stored object trays to substantial proportions before the opening of the body of the storage cabinet are moved out. The stored in the storage cabinet objects are so easily accessible. With a peppy opening of the door of the storage cabinet and a correspondingly transmitted to the slide motion pulse, the slide with the attached object trays can automatically run the second, made possible by the freewheel pull-out.

In order to bring the objects on the object trays back into the storage cabinet, the slide must be pushed back at least from its second extended position to its first extended position, wherein the activation device with the reaching of the first extended position from this direction blocks the freewheel. Thus, due to the restored bidirectional coupling between the door and the movable part of the pull-out rail, the complete return of the slide to the pantry can be effected by pivotally closing the door. Previously, a closing of the door is not yet possible because of the drawn out beyond its first extended position addition storage cabinet of the door in the way. Incidentally, a sweeping pushing back of the slide in the storage cabinet is associated with the fact that the next movement automatically follows due to the inertia of the slide, in this case, returning the movable part of the pull-out from its first extended position to its retracted position with the name door bidirectionally coupled via the drawbar arm. It can be provided for the last retraction of the movable part of the pull-out in its retracted position a self-closing in a conventional manner, which is integrated, for example, in the pull-out.

The Ausziehbeschlag invention can basically find use in Ausziehschränken any width. Particularly advantageous is its use in Ausziehschränken, which have a comparatively small width compared to their depth, so that for a Türmitnehmer that pulls the movable part of the pull-out with a Zugdruckarm from the body of the storage cabinet, distance and travel limits apply that of limit the movable part of the pull-out rail in its pull-out direction when it moves with the door coupled movement. In the pull-out fitting according to the invention, this limitation is accepted for the coupled first pull-out movement. However, the limited way here is supplemented by another way that the movable part of the pull-out rail can travel in the pull-out direction to drive the slide out of the carcass. About this further way move attached to the slide object trays move substantially up to the free edge of the swung-open door, so that it corresponds to the natural handling of the Ausziehbeschlags invention by its user, for the second pull-out movement to the mounted on the slide object trays will attack, in order to prefer these in the pull-out direction or push them against the pull-out direction.

The position of the first extended position, up to which the movement of the movable part of the pull-out rail is bidirectionally coupled from its retracted position to the movement of the door corresponds to a certain pivoting angle or a small pivoting angle range of the door of the storage cabinet due to the hitherto bidirectional coupling. Logically, this pivoting angle range is at or slightly above 90 °, so that the door, the opening of the body of the storage cabinet at least when the movable part of the pull-out rail reaches its first extended position and is activated according to the freewheel for the moving part of the pull-out, in Essentially releases. In order to realize the longest possible way in the pull-out during the first pull-out, the freewheel can be activated only at a larger opening angle of the door. However, in order to then define the position of the door during the second pull-out movement, it makes sense to latch the door in the maximum upright pivot position until the movable part of the pull-out rail is returned from its second extended position to its first extended position. In contrast, when the freewheel is released at an opening angle of the door of about 90 ° and the door is not much further swung open, it is typically trapped between its opening stop and the object trays stored on the slide during the second pull-out movement. The release of the freewheel at an opening angle of the door of 90 ° is advantageously also associated with the fact that only very little space must be left to ensure the function of his Ausziehbeschlags side of the pantry. The storage cabinet can thus also be set up as an end cabinet adjacent to a wall with a door opening towards the wall.

The freewheel, which is connected in series with the Zugdruckarm between the Mitnehmersockel and the movable part of the pull-out, may be provided between the Mitnehmersockel and a lever arm to which the Zugdruckarm is articulated. This lever arm can be mounted pivotably about an axis parallel to the pivot axis to the driver base, wherein the pivotability of the lever arm is blocked relative to the driver base with blocked freewheel. In the second pull-out movement then takes place a pivoting movement of the lever arm relative to the driver base about the axis parallel to the pivot axis. On the other hand, over the first pull-out movement, the lever arm is fixed relative to the driver base.

Specifically, a blocking body attached to the lever arm can be trapped behind a spring-loaded pawl with the freewheel blocked, the pawl, when the movable part of the pull-out rail reaches its first extended position from its retracted position, being retracted by a pulling element of the activating device and thus the blocking body releases. Beyond the first pull-out movement, the lever arm and the carrier base are rigidly coupled to one another by the latch holding the blocking body. Once the pawl is withdrawn from the pulling element, the blocking body can move past the pawl. Thus, the freewheel corresponding relative movement of the lever arm is released relative to the driver socket.

To block the freewheel again, the activation device may have on the pawl an inclined surface over which the blocking body pushes the spring-loaded pawl until it passes behind the pawl and the pawl spring-loaded again protrudes when the movable part of the pull-out his first extended position of reached its second extended position ago.

In principle, the pivotable mounting of the lever arm on the carrier base about the axis parallel to the pivot axis may be formed so stiff that no unwanted movement of the lever arm relative to this axis takes place. Such unwanted movements can be prevented but usually with less effort when the blocking body is guided in a circular arc section-shaped slot in the Mitnehmersockel. The length of this slot defines the maximum distance available for the second pull-out movement. Frequently, however, the second pull-out is practically limited by the striking of the movable part of the pull-out to an internal stop of the pull-out rail.

Concretely, the blocking body may be a mushroom-shaped bolt which projects away from the lever arm and through the slot.

The pawl for catching the blocking body can in principle be guided linearly on the driver base. It is simpler, however, to mount the pawl pivotably about an additional axis parallel to the pivot axis on the driver base. The pawl loading spring may be an attached to the pawl and the driver base tension spring, which is under tensile prestress.

The tension member which retracts the pawl when the movable part of the pull-out rail reaches its first extended position from its retracted position may be hinged at one end to the pawl and supported at its other end by a tension bearing to be fastened to the carcass , In this case, the tension element can basically be a pull rope. In a specific embodiment of Ausziehbeschlags invention, however, the tension element is a dimensionally stable tension arm, which is hinged at its other end to a sliding block, for which has to be fastened to the body train bearing running parallel to the pull-out and ending with an end guide rail. When the sliding block abuts against the end stop, the other end of the tension member can not move any further, and the one end of the tension member then retracts the pawl with respect to the follower base upon further opening of the door about its pivot axis to activate the freewheel.

The freewheel can also be provided between a guided in the pull-out intermediate element to which the Zugdruckarm is articulated, and the movable part of the pull-out rail. At this point it should be emphasized that in principle it is also possible to provide two freewheels, i. H. one between the cam base and the Zugdruckarm and between the Zugdruckarm and the moving part of the pull-out rail. The additional expense associated therewith, however, is usually not justified by an increased functionality of the pull-out fitting.

In the said intermediate element for the freewheel between the Zugdruckarm and the movable part of the pull-out may be a connected between the fixed part and the movable part further movable part of the pull-out rail. In other words, the pull-out fitting may comprise a three-part pull-out rail, wherein the pull-pressure arm hinged to the driver base is articulated at its other end to the middle part of the pull-out rail, which is here referred to as a further movable part of the pull-out rail.

The activation mechanism may define the further movable part on the fixed part and release the movable part relative to the further movable part of the pull-out rail when the movable part of the pull-out rail reaches its first extended position from its retracted position. In the reverse direction of movement of the movable part, the activation mechanism, the movable part on the other movable part set the pull-out rail and release the other movable part relative to the fixed part when the movable part of the pull-out rail reaches its first extended position from its second extended position. In this case, the activation mechanism may have a tilting lever mounted on the further movable part, which tilts when reaching the first extended position, wherein he releases, for example, a bolt and engages behind another bolt, which are provided on the fixed part or the movable part of the pull-out rail. Also from the DE 203 18 735 U1 known technology for controlling the relative movements of the parts of a three-part pull-out rail can be used here.

At the movable part of the pull-out rail, a door stop for the door can be provided. This implies that the door stop may be provided on the slide to be attached to the movable part or on an object tray to be attached to the slide. The door stop is moreover to be designed in such a way that it allows a relative movement of the movable part of the pull-out rail relative to the door, which extends parallel to the pull-out direction, without causing damage. For this purpose, the door stop, for example, have a sliding surface for the driver base fixed to the door or a rotatable roller on which the door strikes itself. For striking the sliding surface of the driver base may have a complementary stop surface. The freely rotatable roller may in particular be rotatably mounted on a front corner of an object tray about an axis of rotation extending parallel to the pivot axis of the door.

When a spring which loads the pawl of the freewheeling activation device between the carrier base and the traction arm presses the door against the door stop via the traction element supported on the body, the position of the door is exactly defined over the second pull-out movement, even if door hinges the door have no detent position at a certain opening angle of the door.

As already mentioned, a frame of the slide, when attached to the movable part of the pull-out rail, preferably extends away from the movable part orthogonally to the pull-out direction, and has fastening means for fixing a plurality of object shelves along its extension. In order to stabilize the slide and the attached object trays in this structure, can for the Pull-out away from the end of the slide a parallel to the pull-out leading linear guide to be attached to the body guide rail to be provided. This guide rail preferably guides the slide past both the first and second pull-out movements.

In order to prevent a tilting movement of the slide about a transverse axis to the pull-out direction, ie a movement of the end of the slide opposite the pull-out rail relative to the attached to the movable part of the pull-out end of the slide, the movements of the two ends of the slide can be synchronized by a synchronization device ,

In concrete terms, the synchronization device can have two toothed rails to be fastened to the body parallel to the pull-out direction in the region of the two ends of the specimen slide and two pinions meshing with one another in each case, rotatably connected to one another via a shaft rotatably mounted on the specimen slide. Other arrangements for reinforced parallel guidance of the slide during its movement out of the storage cabinet can also be used.

A storage cabinet according to the invention with a body having an opening and a door, which is pivotable relative to the body from a closed position in which it closes the opening to an open position in the edge region of the opening in an open position, in which they at least substantially the opening releases, has an Ausziehbeschlag invention.

DESCRIPTION OF THE FIGURES

The in Fig. 1 Ausziehbeschlag 1 shown in an exploded view has a two-part pull-out rail 2 here. The pull-out rail 2 comprises a fixed part 3 to be fixed to the bottom of a cabinet of a supply cabinet and a movable part 5 guided in a pull-out direction 4 relative to the fixed part 3. A slide 6 is to be attached to the movable part 5. The object carrier 6 comprises a frame 7 which is oriented transversely to the pull-out direction 4 and extends away from the movable part 5. Fastening devices 8 for object trays 9 are provided on the frame 7 at different heights. In Fig. 1 only one of the object trays 9 is shown, which is a basket 10 here. The attached to the frame 7 of the slide 6 object trays 9 are free from the frame 7 in the pull-4. The attachment of the slide 6 on the movable part 5 of the pull-out rail 2 via a protruding from the frame 7 mounting arm 11 and from the movable part 5 upwardly projecting mounting bolts 12. For at least partially automatic extraction of the slide 6 with the object trays 9 from a with the Ausziehbeschlag 1 equipped storage cabinet a Türmitnehmer 13 is provided. The Türmitnehmer 13 comprises a driver base 14 which is to be fastened to a aufzuschwenkenden about a vertically extending pivot axis door, and a lever arm 15 which on the driver base 14th about a parallel to the pivot axis of the door extending axis is pivotally mounted, said pivotability is initially blocked, as will be described in detail below. To the lever arm 15 is a Zugdruckarm 16 to steer, which is to be steered with its other end to the frame 7. The pivotability of the lever arm 15 relative to the driver base 14 provides an activatable freewheel that is activated by a tension element 17. The tension element 17 engages with its one end on a spring-loaded pawl, not visible here, which initially blocks the lever arm 15, that is, fixes it on the driver base 14. The other end of the tension element 17 is articulated to a sliding block 18, which is guided in a guide rail 19. The guide rail 19 is to be fastened to the body of the storage cabinet parallel to the withdrawal direction 4, and it has an adjustable end stop 20. When the sliding block 18 abuts against the end stop 20, the pulling element 17 pulls the pawl back and releases the lever arm 15 with respect to the carrier base 14. The present opening angle of the door is adjustable by adjusting the end stop 20. Before the release of the lever arm 15, the door of the respective supply cabinet or the pivoting movement of the door is bidirectionally coupled to the slide 6 or its extension movement in the withdrawal direction 4. When the freewheel between the lever arm 15 and the driver base 14 is released, the slide 6 can also be pulled out in the pull-out direction 4.

So that the entire slide 6 moves exactly in parallel with its pull-out movement, d. H. its end facing away from the pull-out rail 2 is as far as its end fixed to the movable part 5 of the pull-out rail 2, a synchronization device 21 is provided. The synchronization device 21 comprises a lower toothed rail 22 and an upper toothed rail 23. A lower pinion 24 meshes with the lower toothed rail 22. A shaft (not visible here) rotatably mounted in a shaft housing 25 rotatably connects the lower pinion 24 to an upper pinion 26 Pinion 26 meshes with the upper rack rail 23. By forming the combinations of pinions 24 and 26 and rack rails 22 and 23, respectively, the lower and upper ends of the frame 7, to which the shaft housing 25 is fixed, move Extraction direction 4 completely synchronous.

The pinions 24 and 26 can be held by guide edges 27 and 28 in their engagement in the tooth rails 22 and 23. For lateral guidance of the upper end of the slide 6, an additional guide rail 29 is provided, engage in the guide rollers 30, the at mounted Ausziehbeschlag 1 are mounted on the frame 7 via an elbow 31. For fastening the shaft housing 25 to the frame 7 screws 32 are provided.

The Fig. 2 to 4 show the Ausziehbeschlag 1 mounted in a storage cabinet 33 with a body 34 and a pivotable about a vertical pivot axis relative to the body 34 door 35. The pull-2 with its fixed part 3 is also attached to the body 34 as the tooth rails 22 and 23 and the Here not visible guide rails 19 and 29. The driver base 14 is attached to the door 35 which is pivotally mounted on door hinges 36 to the body 34. By opening the door 35 from its closed position according to Fig. 2 according to their open position Fig. 3 For example, the slide 6, which is initially bidirectionally bidirectionally coupled to the door 35 via the door driver 13, extracts a first path from the body 34. The Zugdruckarm 16 engages with a tensile force on the frame 7. Another extraction movement of the slide 6 from the storage cabinet 33 from the first extended position according to Fig. 3 in a second extended position according to Fig. 4 allows the freewheel between the attached to the door 35 driver base 14 and the lever arm 15. By the lever arm 35 relative to the driver base 14 about its parallel to the pivot axis of the door 35 extending axis further forward pivots, the pivot point of the Zugdruckarms 16 to the Frame 7 continue to run forward and thus the entire slide 6 with the attached object trays 9 continue to get out of the body 34 out. It is off Fig. 4 It can be seen that in order to guide this additional pivotal movement of the lever arm 15 relative to the driver base 14, a slot 37 is provided in the driver base 14. The opening angle of the door 35 in Fig. 4 is shown larger than it is necessary for reaching the maximum extended position of the slide. Rather, it is preferable to define the position of the door 35 even with the slide 6 maximally pulled out, when the door 35 is supported on the movable part 5 of the pull-out rail 2 via a door stop 38. For this purpose, a stop surface 39 is formed on the driver base 14, which in accordance with the door stop 38 during the relative movement of the movable part 5 relative to the door 35 between the first extended position Fig. 3 and the second extended position according to Fig. 4 slides.

For re-closing the supply cabinet 33, first the slide 6 with the attached object trays 9 is moved out of the position according to FIG Fig. 4 in the position according to Fig. 3 pushed back. If he is then pushed back further, he takes the again coupled door 35 with. Alternatively, it can by closing the door 35 in its retracted position according to Fig. 1 to be led back.

The Fig. 5 to 7 explain how the freewheel between the driver base 14 and the lever arm 15 upon reaching the first extended position according to Fig. 3 from the direction of the inserted position according to Fig. 2 released and from the direction of the second extended position according to Fig. 4 is blocked again. The tension member 17 engages a pawl 40 which is pivotally mounted about a further parallel to the pivot axis of the door extending axis of the driver base 14 and is acted upon by a tension spring 41 in a position in which they a bolt-shaped blocking body 42 of the lever arm 15th , which is guided in the slot 37, at one end of the slot 37 catches. First, the blocking body 42 is caught by the pawl 40, such as Fig. 5 with the door closed 35 shows. Upon reaching the first extended position pulls the pull element 17, the pawl 40 against the force of the tension spring 41 back. This is in Fig. 6 shown. When released blocking body 42 of the freewheel between the lever arm 15 and the driver base 14 is activated. At the same time, the door 35 can not return to its closed position because the abutment surface 39 abuts on the Türmitnehmer 14 to the door stop 38 on the movable part 5. In this stop, it is held by the tension spring 41, which is supported on the body 34 via the tension element 17. When reinserting the slide 6 with the movable part 5 of the blocking body 42 pushes the pawl 40 back on an inclined surface 43 and thus returns to its captive position behind the pawl 40. Thus, the pivotal movement of the door 35 is again bidirectional with the extension movement of the movable part 5 and attached to the slide 6 in the pull-4.
