Abstract

A journal (24) is secured to a side wall of each drawer (2, 3). A guide rail (8) is secured to the furniture frame (1). A holder (18, 18a) is associated with each journal and can be moved between two stops (15, 30) in the guide rail along an adjustment axis (19), the holders being supported against each other in the axial direction. A spring (16) is urged against the first stop (15) and directly against one of the holders so that all of these holders are urged against the second stop (30). A catch part (21, 21a) is associated with each holder and can be pivoted between a locking position when the drawer is pushed in and an open position when the drawer is pulled out. An adjustment space (23) which can receive the journal is used to pivot the catch part by moving the drawer and is open on the side facing the first stop when the catch part is in the locking position. The catch part is axially supported against the spring directly via an adjustment contour (25) and when the catch part is in the open position all the holders are supported directly against the first and second stops, preventing an axial displacement and also preventing the other catch parts from being pivoted. A central lock unit (33) cooperates with the holder so that when it is moved from the open position into the locked position all the holders are urged against the first stop and against the force of the spring.

Description

The invention relates to a pull-out for in a body of a piece of furniture on top of each other and in parallel sliding planes slidably arranged drawers with means for centrally closing all drawers in an inserted position.

In DE 195 47 049 C2 a pull-out for superimposed drawers is described according to the preamble of claim 1. This comprises arranged on a guide rod arranged locking elements, wherein a locking element is provided for each drawer. The locking elements each have a slot. They are added via holding elements alternately with adjusting elements in a guide rail. The bottom drawer associated locking element is supported via a compression spring against a stop of the guide rail. It is arranged displaceably in the guide rail via a holding element. It is pivotally mounted on the support member about a pivot axis and has eccentric to the pivot axis to a setting slot, to which in the closed state of the associated drawer attached to a side wall of the drawer pin element is engaged. The locking element furthermore has a setting contour which acts on a support surface belonging to an actuating element arranged above it. The actuator in turn acts on the retaining element of the above and thus also arranged at the top position locking element.

This in turn acts on a locking element, which carries a locking pin, of the guide rail to the front, ie of the associated side wall of the Furniture away, projects. On the locking pin acts a locking pin of a lock cylinder. The locking pin is arranged on the cylinder core eccentric to the axis of rotation. To close the drawers of the locking pin of the lock cylinder acts on the locking pin such that the column formed from the arrangement of adjusting elements and locking elements and retaining elements is moved against the force of the lower end arranged compression spring down. This ensures that even when pulling on one of the drawers is acted, the associated locking element can not pivot because the located below the operated drawer control elements or locking elements can not move down. In the unlocked state occurs when operating a drawer pivotal adjustment of the associated locking element and an adjustment of the underlying components in the guide rail against the force of the compression spring down, so that another drawer can not be pulled out. For the adjustment of another component, ie for the extension of the column is no way in the guide rail more available.

A disadvantage of this arrangement is that upon actuation of a drawer, the associated locking element on the one hand pivots and on the other hand is displaced even in the guide rail down. As a result, the pin member is further displaced in the slot, d. H. displaced in the direction of a position which is located farther from the axial opening of the slot and closer to the pivot axis of the locking element. The leverage when opening a drawer, which are required to easily pivot the locking element, thus deteriorate. In addition, the slot must be made correspondingly long.

The Ausziehsperre according to DE 200 08 266 U1 addresses these disadvantages by the top drawer associated locking element is supported via a compression spring against an upper stop of the guide rail. When pivoting the locking elements, these are thus supported against the arranged below the respective locking element control elements without being axially displaced.

At the upper end also a blocking element is arranged with a locking pin, against which a locking pin of a lock cylinder can be supported, wherein for locking the locking pin, a displacement of the locking element upwards and thus a displacement of the underlying retaining elements is prevented. The column of holding elements and actuators is not displaced axially during locking.

The disadvantage here is that in the locked state of the Ausziehspeer a large lever arm between the pin elements and the locking elements is effective, so that even low extraction forces can lead to failure of a component.

In EP 1 148 194 A2 a similar pull-out lock is shown, which basically has the same arrangement as the pull-out lock according to DE 195 47 049 C2. However, two columns of holding elements are arranged in mirror image to each other, wherein the spring element between the two columns is arranged and at this point, the central clamping unit is provided.

The invention has for its object to provide a pull-out, which ensures improved leverage when opening the drawers between the pin elements and the associated locking elements and on the other hand a higher resistance to extraction forces in the locked state.

• a central locking unit,
  • which is adjustable between a release position and a closed position, wherein the closing unit cooperates with the holding elements in such a way that it transfers all retaining elements against the spring force of the spring element against the first stop by transferring it from the release position into the closed position,

wherein, in the release position of the central closing unit, the pin elements each viewed in projection on the adjustment axis are arranged at a smaller distance than the pivot axis of the associated locking element to the first stop, characterized in that
in the closed position of the central closing unit, the pin elements are each viewed in projection on the adjustment considered at the same distance as or at a greater distance than the pivot axis of the associated locking element to the first stop.

This arrangement ensures that when moving a drawer, the associated locking element is merely pivoted, without it being displaced axially in the direction of the adjustment axis. As a result, always a large lever arm between the adjusting pin and the pivot axis of the locking element is effective. Furthermore, it is ensured that when locking the pull-out lock by transferring the closing unit in its closed position all holding elements and thus all locking elements in the direction of the first stop are displaced. As a result, the effective lever arm between the pin elements and the pivot axes of the respective locking elements is reduced, so that act with exhaust forces acting on a drawer, little or no torque to the locking element. This ensures the greatest possible resistance of the pull-out against pull-out forces.

Furthermore, always a lever arm between the pin elements and the pivot axis of the respective locking element is effective when the closing unit is in its release position and the drawers are extendable. The larger the effective lever arm, the easier it is to overcome the spring force for pivoting the locking elements. In contrast, according to the invention no lever arm is effective when the central locking unit is in its closed position and the pin elements are arranged such that they are each viewed in projection on the displacement plane at the same distance as the pivot axis of the associated locking element are arranged to the first stop. Thus, in the closed position of the central clamping unit in an attempt to open a drawer, no torque is exerted on the locking elements. It will no axial forces exerted on those holding elements, which are supported against the control contour of the respective locking element. According to the invention, it can also have an advantageous effect if the pin elements are arranged in such a way that, viewed in projection on the displacement plane, they are arranged at a greater distance than the pivot axis of the associated locking element relative to the first stop. In this case, when a pull-out force acts on a drawer, an opposite torque is exerted on the locking elements than is the case when the central locking unit is in the release position.

By means of these measures, the maximum extraction forces, up to which the pull-out lock secures a drawer against being pulled out, if the central closing unit is in the closed position, can be increased. This provides increased security against attempts to forcibly open a drawer.

Preferably, the adjustment axis is arranged at a right angle to the shift planes. The adjustment axis can be arranged vertically in the body.

A particularly compact design can be achieved in that the adjusting recesses in the blocking position of the respective locking element parallel to the adjustment axis and are each arranged in a plane which is formed by the adjustment axis and the pivot axis of the respective locking element.

Thus, in the event that the pin elements are each viewed in projection on the displacement plane at the same distance as the pivot axis of the associated locking element to the first stop, the pin elements are arranged coaxially to the respective pivot axis. This results in a particularly resistant structural design of the locking elements.

The control contours can have in the pivoting sense of the blocking position to the open position a partial area with increasing distance to the respective pivot axis. The locking elements can then each axially with their control contour be supported a stall stop of an actuating element, wherein the adjusting elements are axially displaceably guided on the guide rail.

In order to ensure a defined blocking position and a defined open position of the locking element, the control contours each have a first latching point for holding the respective locking element in its blocking position and a second latching point for holding the respective locking element in its open position.

In a particularly simple embodiment of the parking stops these are held in sliding contact with the respective control contour.

It is preferably provided that the pin elements each have a pin axis which runs parallel to the pivot axis of the associated locking element, and that the pin elements in each case in the position in which they are transferred to the adjusting recess, engage in the adjusting recess.

In order to carry out the locking elements particularly stable, it can be provided that the locking elements are each formed by a disc having a peripheral edge, wherein a portion of the peripheral edge forms the setting contour, and that in the disc a groove serves as a positioning recess, the parallel to the pivot axis shelves and forms a perpendicular to the pivot axis arranged base surface, wherein the respective pin element can be supported against the shelves and the pivot axis intersects the base surface.

Due to the configuration of the adjusting recess as a groove whose shelves are connected to each other via the base, the shelves can absorb particularly high forces. In this case, the setting contour preferably limits the shelves and the base area for opening the positioning recess.

For locking the pull-out can be provided that the holding elements are indirectly supported via a locking element against the second stop.

The blocking element is displaceably guided along the adjustment axis to the guide rail and has a locking pin. The closing unit comprises a lock cylinder with a cylinder core and the cylinder core carries a locking pin, which sets the locking pin in the closed position. As a closing unit but other locking systems, such. B. a push rod lock, are used.

A preferred embodiment of the invention and its application to a piece of furniture is shown in the drawings.

FIG. 1 shows a piece of furniture 4 that has a body 1 in which three drawers 2, 3 are arranged one above the other. The drawers 2, 3 can be moved in the body 1 between an extended and the retracted position shown. To ensure that only one Drawer 2, 3 can be pulled out and all drawers 2, 3 can be centrally locked together in their retracted position, a closing arrangement 7 is provided, which is arranged on an inner surface 6 of a side wall 5 of the body 1 and which by means of a lock cylinder 33, the is accessible from a front side of the side wall 5, cooperates. On the drawer side, the closing order works 7 with a arranged on the opposite side wall of the drawer pin element for locking or releasing a drawer together.

As shown in Figure 2, the closing assembly 7 comprises a guide rail 8, which is C-shaped, so that a front open side 9, a closed back 10, with the guide rail 8 rests against the side wall 5, and two narrow sides eleventh , 12 result. Furthermore, the guide rail 8 has a lower end 13, which is arranged near the lower drawer 3 in the body 1 according to Figure 1, and an upper end 14, which is adjacent to the uppermost drawer 2, on. At or near the lower end 13, a first stop 15 is arranged, which can be formed by punching and pushing out of the wall of the back 10 or by an inserted into the C-shaped guide rail 8 stop element. The first stop 15 is held immovably in the guide rail 8.

A first adjusting element 17 is displaceably guided in the guide rail 8 along an adjustment axis 19. The first actuating element 17 is supported axially against the first stop 15 via a spring element 16.

Above the first actuating element 17 is supported axially against this, a holding element 18 from which is also guided axially displaceable along the adjustment axis 19 in the guide rail 8. The holding member 18 carries a pin 20 on which a locking element 21 is pivotally mounted about a pivot axis 22. The locking element 21 has a positioning recess 23 into which a pin element 24 engages, which is assigned to the lower drawer 3. In the retracted state of the lower drawer 3, the adjusting recess 23 extends vertically, ie parallel to the adjustment axis 19. Further, the locking element 21 has a setting contour 25, via which the locking element 21 is supported against an actuating stop 26 of the first actuating element 17. The parking stop 26 protrudes at right angles from the adjustment axis 19 in the direction of the drawer 3 from the guide rail 8. The control contour 25 has a partial distance to an increasing distance to the pivot axis 22, and for a pivoting counterclockwise direction according to the view 2, above the holding element 18, a second adjusting element 27 is supported axially against the holding element 18, wherein the second adjusting element 27 as well as the holding element 18 along the adjustment axis 19 slidably guided in the guide rail 8.

A further arrangement is supported against the second adjusting element 27 by a first adjusting element 17a, a holding element 18a and a second adjusting element 27a, this arrangement being designed in accordance with the previous arrangement and associated with the upper drawer 2.

The second control element 27a of the upper arrangement is supported axially upward against a blocking element 28, which is displaceably guided in the guide rail 8 along the adjustment axis 19. The blocking element 28 has a locking pin 29 which protrudes parallel to the pivot axis 22 in the direction of the drawer 2 from the guide rail 8.

The spring element 16 acts on all the first adjusting elements 17, 17a, all holding elements 18, 18a and all second adjusting elements 27, 27a and the blocking element 28, which together form a column, against a second stop 30, at or near the upper end 14 of the guide rail. 8 is arranged. The second stop 30 is held as the first stop 15 is not displaceable in the guide rail 8.

The guide rail 8 of the closing arrangement 7 is embedded in a groove 31 of the side wall 5 and fixed by means of tabs 32. At the upper end 14 of the guide rail 8, a closing unit in the form of a lock cylinder 33 is provided. The lock cylinder 33 has a cylinder core 34 which carries a locking pin 36 eccentrically to its axis of rotation 35. The locking pin 36 cooperates with the locking pin 29 of the locking element 28. In the position shown in Figure 2, the lock cylinder 33 and thus the locking pin 36 is in a release position in which the drawers 2, 3 can be opened. By transferring the lock cylinder 33 in a closed position, as shown in Figure 4, the entire column against the spring force of the spring element 16 against the first stop 15 shifted vertically downwards.

The function of the pull-out is to be explained in more detail below with reference to the lower drawer 3. The lower drawer 3 can be pulled out of the body 1 of the cabinet in a displacement plane 37. By pulling out the lower drawer 3, the locking element 21 is pivoted about the pivot axis 22 in the counterclockwise direction, since the pin member 24 which is connected to the lower drawer 3, engages in the retracted position of the lower drawer 3 in the adjusting recess 23 of the locking element 21 , After exceeding a certain position when pulling out the lower drawer 3, the pin member 24 slides out of the adjusting recess 23, wherein the locking element 21 is then in the open position. When pulling out the drawer 3 is supported for pivoting the locking element 21, the pin member 24 from a first footprint 38, which is formed by the adjusting recess 23 and parallel to the pivot axis 22 extends. When pushing in the lower drawer 3, the pin member 24 is supported against a second footprint 39, which is also formed by the adjusting recess 23. The adjusting recess 23 is shown in the form of a groove which is incorporated in a disc 41 which forms the locking element 21. The groove thus forms a base 42, which connects the first footprint 38 and the second footprint 39 with each other and thus ensures a rigid structure of the locking element 21. The disk 41 further has around the pivot axis 22 a peripheral edge 43, which forms the control contour 25.

In the locking position of the locking element 21, the adjusting recess 23 is aligned parallel to the adjusting axis 19, wherein the adjusting recess 23 has an opening 40 in the direction of the first stop 15. In the open position of the locking element 21, the adjusting recess 23 is aligned at an angle to the adjustment axis 19, so that the pin member 24 can escape from the opening 40 of the adjusting recess 23.

Since the setting contour 25 is formed such that the distance from the setting contour 25 to the pivot axis 22 increases when the locking element 21 is pivoted counterclockwise, the first adjusting element 17 is displaced vertically against the spring force of the spring element 16 until it Attachment to first stop 15 is. Since the holding element 18 is supported vertically above the column upwards against the second stop 30, the holding element 18 does not move along the adjustment axis 19 during pivoting of the locking element 21. In order to ensure defined pivoting positions of the locking element 21 in the blocking position and in the open position, For example, the adjusting contour 25 has a first latching point 44 for holding the latching element 21 in its blocking position and a second latching point 45 for holding the latching element 21 in its open position.

After pulling out the drawer 3 is the pull-out in the position shown in Figure 3. In this, the spring travel of the spring element 16 is used up, so that all elements of the column against the first stop 15 and against the second stop 30 are supported. This ensures that no further locking element 21a can be pivoted. This ensures that no further drawer 2 can be pulled out when one of the drawers 3 is open. Furthermore, due to the limited spring travel of the spring element 16 ensures that not two drawers 2, 3 can be opened simultaneously.

To lock the pull-out lock, as described above, the lock cylinder 33 is transferred to its closed position. This is only possible if so that all drawers 2, 3 in its retracted position and all locking elements 21, 21a are in their locked position. By transferring the lock cylinder 33 in the closed position, the entire column is displaced vertically downward against the spring force of the spring element 16 against the first stop 15. The pull-out is thus in the position shown in Figure 4. A pivoting of the locking elements 21, 21a is no longer possible because the column is supported on the one hand against the first stop 15 and the other against the locking pin 36 and the spring travel of the spring element 16 is used up.

On the basis of the lower drawer 3, the closed position is explained in detail. In the closed position of the lock cylinder 33, the pin member 24 is vertically at the same height as the pivot axis 22. This means that the vertical distance viewed in projection on the Verstellachse 19 between the pin member 24 and the first stop 15 is equal to the vertical distance in projection on the adjustment axis 19 viewed between the pivot axis 22 and the stop 15. That is, the pin member 24 and the pivot axis 22 are arranged vertically at the same height. This ensures that the pivot axis 22 and the pin member 24 is disposed in the sliding plane of the lower drawer 3. Thus, there is no torque about the pivot axis 22 when trying to pull out the lower drawer 3.

It can be realized an alternative according to the invention, in which the pin member 24 viewed in projection on the Verstellachse 19 occupies a greater distance from the first stop 15 as the pivot axis 22. That is, the pin member 24 is disposed vertically higher than the pivot axis. Thus, in an attempt to extract the lower drawer 3, a torque is generated about the pivot axis 22, which counteracts the torque which is required for pivoting the locking element 21 from the locked position to the open position. Thus, a secure hold of the drawer 4 is ensured in the retracted position.

6. An interlock arrangement according to any one of claims 1 to 5,
   characterised in
   that the setting contours (25) each comprise a first engagement point (44) for holding the respective bolt element (21,21 a) in its locking position and a second engagement point (45) for holding the respective bolt element (21, 21 a) in its open position.
7. An interlock arrangement according to any one of claims 5 or 6,
   characterised in
   that the setting stops (26) are held in a sliding contact with the respective setting contour (25).
8. An interlock arrangement according to any one of claims 1 to 7,
   characterised in
   that the journal elements (24) each comprise a journal axis which extends parallel to the pivot axis (22) of the associated bolt element (21, 21 a), and that, in the position in which they are transferred to engage the setting recess (23), the journal elements (24) enter the setting recess (23).
9. An interlock arrangement according to claim 8,
   characterised in
   that the bolt elements (21, 21 a) are each formed by a disc (41) with a circumferential edge (43),wherein a partial portion of the circumferential edge (43) forms the setting contour (25), and
   that in the disc (41), a groove serves as a setting recess (25) which forms setting faces (38, 39) extending parallel to the pivot axis (22) and a basal face (42) arranged at a right angle to the pivot axis (22), wherein the respective journal element (24) can be supported against the setting faces (38, 39) and wherein the pivot axis (22) intersects the basal face (42).
10. An interlock arrangement according to claim 9,
    characterised in
    that the setting contour (25) delimits the setting faces (38, 39) and the basal face (42) towards the opening (40) of the setting recess (23).
11. An interlock arrangement according to any one of claims 1 to 10,
    characterised in
    that the holding elements (18, 18a) are indirectly supported via a locking element (28) against the second stop (30),
    that the locking element (28) is guided along the setting axis (19) so as to be displaceable relative to the guiding rail (8) and comprises a locking journal (29),
