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

Extraction lock device for drawers arranged on top of each other.

The present invention relates to a Extraction locking device for drawers arranged in a body of a piece of furniture on top of each other and movable in planes of parallel displacement with means for the central closure of all the drawers in an inserted position.

Document DE 195 47 049 C2 describes a Extraction locking device for drawers arranged about over others according to the preamble of claim 1. This comprises arranged closing elements distributed in a bar of guidance, being provided for each drawer a closing element. The closing elements have a slit in each case. Is it so housed by fasteners, alternated with adjustment elements, in a guide rail. The closing element assigned to the bottom drawer is supported, through a spring pressure, against a stop of the guide rail. Is willing movable in the guide rail by means of a clamping element. It is arranged in the clamping element, tiltable around a tilt axis, and presents, eccentrically with respect to the tilt axis, an adjustment slit with respect to which, in the closed state of the corresponding drawer, an element is crimped of pin arranged on the side wall of the drawer. The element of closure also has an adjustment contour, which loads a support surface belonging to an adjustment element arranged over. The adjustment element loads the element of fastening of the closure element located above and with it also of arranged in the upper position.

This again loads a blocking element, which carries a locking pin, which protrudes out of the rail of guided, that is, moving away from the corresponding side wall of the piece of furniture. On the locking pin acts a closing pin of a closing cylinder The closing pin is arranged in the core of the eccentric cylinder with respect to its tilting axis. For close the drawers the closing pin of the loading closing cylinder in such a way the locking pin, that the column, forms by the arrangement of adjustment elements and closing elements as well as fasteners, is displaced against the force of the spring of pressure arranged at the lower end. This ensures that, even when acting by pulling one of the drawers, the element corresponding closure can not tilt, since the elements of adjustment or closing elements that are under the drawer can not be turned further down. In the state unlocked takes place, during the operation of a drawer, a tilt shift of the corresponding closing element and an adjustment of the construction pieces found below in the guide rail, down, against the spring force of pressure, so that another drawer can no longer be removed. For him adjustment of another construction piece, that is, for the extension of the column no longer has any route in the lane of guided.

In this provision it is disadvantageous that at actuate a drawer the corresponding closing element is, by a side, tilted and, on the other, displaced himself down in the guide rail. This continues to move the element of spike in the slit, that is, it moves in the direction of a position which is disposed farther from the axial opening of the slit and closer to the tilt axis of the element of closing. The lever ratios when opening the drawer, which are necessary to slightly swing the closing element, They get worse accordingly. In addition, the slit must be made correspondingly long.

The extraction locking device according to the Document DE 200 08 266 U1 faces these disadvantages thanks to that the closing element assigned to the upper drawer is supported, to through a pressure spring, against an upper rail stop Guided When the closing elements are tilted, they are supported by consequent against the adjustment elements, arranged in each case below the corresponding closing element, without being axially displaced.

In the upper end it is also arranged a locking element with a locking pin against which it Can support a locking pin of a closing cylinder, avoiding a displacement for locking the locking pin of the locking element upwards and thereby a displacement of the fasteners arranged below. The formed column by fasteners and adjustment elements is displaced axially when blocking.

Here it acts disadvantageously than in the locked state of the extraction lock actuate a lever arm greater between the spindle elements and the closing elements, of way that already for small forces of extraction can lead to a failure of a constructive piece.

In EP 1 148 194 A2 is represented a similar extraction blocking device which it presents, essentially, the same arrangement as the device Extraction block according to DE 195 47 049 C2. Without However, two columns of fasteners are arranged with mirror symmetry with respect to each other, the spring element between the two columns and being provided in This place also the central locking unit.

The invention poses the problem of proposing an extraction locking device which, on the one hand, guarantees improved lever ratios by opening the drawers between the spindle elements and the corresponding elements.
of closing and, on the other, a greater capacity of resistance against forces of extraction in the locked state.

This problem is solved according to the invention. by means of an extraction device for drawer extraction arranged in a body of a piece of furniture on top of each other and that can move in parallel displacement planes with means for central locking of all drawers in one position inserted that comprises

-

a tang element per drawer for attachment to a side wall of the corresponding drawer,

-

a guide rail,

-

he which is attached to the body of the furniture,

-

fasteners,

-

the which are assigned in each case to an element of spike,

-

the which are guided, between a first stop and a second stop of the guide rail, along the guide rail movable to length of an adjustment shaft, and

-

the which are supported at least indirectly axially ones against others,

-

a spring element,

-

he which is leaning against the first stop and at least indirectly against one of the fasteners and load all the elements clamping against the second stop,

-

 a closure element for each clamping element,

-

that It is rotatable in each case in the clamping element around a tilt axis between a locked position, the which corresponds to an inserted position of the corresponding drawer, and an opening position, which corresponds to a position removed from the corresponding drawer,

-

that it presents an adjustment recess,

- to which can be moved in each case the pin element in crimp,

- which serves, by moving the corresponding drawer for the rotation of the closure element, and

- that in the locked position of the closing element is open towards the first stop (15),

-

that It has an adjustment contour,

-

to through which in each case the closure element is supported, at least indirectly, axially against the element of spring,

-

being, in the opening position of the closure element, all fasteners supported, at less indirectly, against the first stop and the second stop, and being prevented from performing an axial displacement and all remaining closing elements being prevented from making a tilt

-

a central locking unit,

-

That you can adjust between an unlocked position and a position of closing, interacting the closing unit in such a way with the fasteners that, by transfer from the position of unlock to the closed position, move all the elements of clamping, against the spring force of the spring element, against the first stop,

being ready, in the unlocked position of the central locking unit, in each case the elements of pin, seen in projection on the adjustment axis, at a distance less than the tilt axis of the closing element corresponding to the first stop, characterized in that in the closing position of the central locking unit the elements of spike are arranged in each case, seen in projection on the axis of adjustment, at the same distance as or at a distance greater than the tilt axis of the corresponding closing element regarding the first stop.

Thanks to this provision it is guaranteed that, when moving a drawer, the corresponding closing element is only tilted without being displaced axially in the direction of the adjustment axis. This is permanently active. a large lever arm between the adjustment pins and the shaft of tilt of the closing element. In addition, it is guaranteed that at lock the extraction locking device by the transfer of the closing unit to its closing position all fasteners and therefore all the elements of closure can be moved in the direction of the first stop. With that the active lever arm between the pin elements and the tilt axes of the corresponding closing elements, so that in the case of extraction forces, which act on the drawer, act only small or no turning moments moment of rotation on the closing element. Thanks to that, I know guarantees a resistance capacity as large as possible Extraction locking device with respect to the forces of extraction.

In addition, a permanent arm of lever between the spindle elements and the tilt shaft of the corresponding closing element, when the closing unit is it is in its unlocked position and the drawers can be extract. The larger the active lever arm the more simple is to overcome the spring force to swing the elements of closing. On the contrary, according to the invention, it is not active no lever arm when the central locking unit is is in its closed position and the spike elements are arranged in such a way that, seen in projection on the plane of displacement, are at the same distance as the tilt axis of the corresponding closing element with respect to the first stop. By consequently, it is not exercised in the closed position of the unit of central closing, during the attempt to open a drawer, no time of rotation on the closing elements. Axial forces are not exerted on those fasteners that are supported against the adjustment contour of the corresponding closure element. According to invention may also have an advantageous effect that the elements of spike are arranged in such a way that, seen in each case in projection on the displacement plane, be ready to distance greater than the pivot axis of the closing element corresponding to the first stop. At the same time it is exercised, during the performance of the extraction force on a drawer, a opposite turning moment on the closing elements such as the case when the central locking unit is in position Unlock

Thanks to these measures you can increase the maximum extraction forces, except that which ensures with the Extraction locking device a drawer against extraction, in the extent to which the central locking unit is in the closing position This offers greater security against attempts of opening a drawer by force.

Preferably the adjustment axis is arranged forming a right angle to the displacement planes. The adjustment axis can be arranged vertically in the body.

An especially compact constructive form is can be achieved thanks to the adjustment recesses run, in the locking position of the corresponding closure element, parallel to the axis of adjustment and in each case they are arranged in a plane which is formed by the axis of adjustment and the axis of tilting of the corresponding closing element.

Therefore, in the case where spike elements, seen in each case in projection on the plane of displacement, are arranged at the same distance as the tilting axis of the corresponding closing element with respect to the first stop, the spindle elements are arranged coaxially with respect to the corresponding tilt axis. With this results in a particularly strong structuring of the elements of closing elements.

Adjustment contours may present, in the tilt direction from the closed position to the position of opening, a partial area with increasing distance from the corresponding tilt axis. The closing elements can be supported then, in each case, with its adjustment contour against an adjustment stop of an adjustment element, the axially movable guided adjustment elements in the rail guided.

To ensure a defined lock position and a defined opening position of the closing element, the adjustment contours present in each case a first resting point for securing the corresponding closure element in its locking position and a second resting point for clamping of the corresponding closing element in its position of opening.

In a particularly simple structuring of the adjustment stops are subject to sliding contact with respect to the corresponding adjustment contour.

It is preferably provided that the elements of spike present in each case a spindle shaft, which runs parallel to the tilt axis of the closing element corresponding, and because the spike elements are inserted, in each case in the position in which they are moved to engage in the adjustment recess, in the adjustment recess.

In order to make the closing elements especially resistant, it can be provided that closure elements are formed in each case by a plate with a peripheral edge, in which a partial section of the peripheral edge form the adjustment contour, and on the plate a groove serves as adjustment recess, which forms parallel adjustment surfaces with respect to the tilting axis and an arranged base surface forming a right angle to the tilt axis, being resting the corresponding pin element against the surfaces of adjustment and cutting the tilt axis the surface of base.

By structuring the recess of adjustment as a groove, whose adjustment surfaces are connected each other using the base surface, the adjustment surfaces They can absorb great forces. The adjustment contour limits the same time preferably the adjustment surfaces and the base surface towards the opening of the adjustment recess.

For locking the locking device of removal can be provided that the fasteners are supported indirectly, through a blocking element, against The second stop.

The blocking element is guided, movable along the adjustment axis, with respect to the guide rail and It has a locking pin. The closing unit comprises a closing cylinder with a cylinder core, and the core of the cylinder carries a locking pin, which immobilizes the pin lock in the closed position. As closing unit you can however, also use other closing systems as per example a push bar closure.

Figure 2 shows a view of the device of Extraction lock and closing unit on the side wall of the furniture, in which all the closing elements are represented in its locked position and the closing unit central is in its unlocked position;

Figure 3 shows a view according to Figure 2, in which a closing element is represented in its position open, and

Figure 4 shows a view according to Figure 2, in which the central locking unit is represented in its closing position

In Figure 1 a piece of furniture 4 is shown, the which has a body 1, in which three drawers are arranged 2, 3 over each other. The drawers 2, 3 can be moved in the body 1 between an extracted position and an inserted position represented. To ensure that in each case it can be extracted only one drawer 2, 3 and that all drawers 2, 3 can be locked together centrally in its inserted position, a closing device 7 is provided, which is arranged in an inner surface 6 of a side wall 5 of the body 1 and the which interacts by means of a closing cylinder 33, which is accessible from a front side of the side wall 5. On the side from the drawer the closing device 7 collaborates, for blocking or unlocking a drawer, with a pin element arranged in the opposite side wall in the drawer.

As depicted in Figure 2, the closing device 7 comprises a guide rail 8, which it is structured in a C-shape, so that it turns out a side 9 open front, a back side 10 closed, with which the guide rail 8 is in contact with the side wall 5, and two narrow sides 11, 12. In addition, the guide rail 8 has a lower end 13, which is arranged near drawer 3 lower in body 1 according to Figure 1, and an upper end 14, which is adjacent to the upper drawer 2. At or near the end 13 bottom one first stop 15 is arranged, which may be formed by stamping and pressure extraction of the side wall rear 10 or by means of a stop element inserted in the rail of guiding 8 in the form of C. The first stop 15 is held so not movable in the guide rail 8.

A first adjustment element 17 is guided by so that it can be moved, along an adjustment axis 19, in the guide rail 8. The first adjustment element 17 is supported axially, by means of a spring element 16, against the first stop 15.

Above the first adjustment element 17 is supports, axially against it, a fastener 18, which it is also guided, axially movable, along the axis of adjustment 19 of the guide rail 8. The clamping element 18 carries a pin 20, on which a closure element 21 is arranged tilt around a tilt axis 22. The element of closure 21 has an adjustment recess 23, in which it crimps a pin element 24, which is assigned to the lower drawer 3. In the inserted state of the lower drawer 3 the adjustment recess 23 runs vertically, that is, parallel to the axis of adjustment 19. In addition, the closure element 21 has a contour of setting 25, through which the closure element 21 is supported against an adjustment stop 26 of the first adjustment element 17. The adjustment stop 26 protrudes, forming a right angle, in front of the shaft setting 19 in the direction of drawer 3 in front of the rail guided 8. Adjustment contour 25 presents, along a partial travel, a distance that increases with respect to the axis of tilt 22, and this for a sense of counterclockwise tilt according to the view of Figure 2. Above the clamping element 18 a second adjustment element 27 rests axially against the holding element 18, the second element being guided adjustment 27 same as holding element 18, movable to length of the adjustment shaft 19, in the guide rail 8.

Against the second adjustment element 27 is supported another device formed by a first adjustment element 17a, a fastener 18a and a second adjustment element 27a, this device being structured in correspondence with the previous device and being assigned to the upper drawer 2.

       \ newpage
    

The second adjustment element 27a of the upper device leans at the same time axially towards above against a blocking element 28 which is guided, movable along the adjustment axis 19, in the guide rail 8. The locking element 28 has a locking pin 29, the which protrudes from guide rail 8, parallel to the axis of tilting 22, towards the drawer 2.

The spring element 16 loads all of first adjustment elements 17, 17a, all elements of clamping 18, 18a and all second adjustment elements 27, 27a as well as the blocking element 28, which together form a column, against a second stop 30, which is arranged in or near the upper end 14 of the guide rail 8. The second stop 30 is attached, as is the first stop 15, not movable in the guide rail 8.

The guide rail 8 of the closing device 7 is countersunk in a groove 31 of the side wall 5 and is fixed by flanges 32. At the upper end 14 of the rail guided 8 is provided a closing unit in the form of a cylinder of closing 33. The closing cylinder 33 has a core of the cylinder 34 which carries, eccentrically with respect to its axis of turn 35, a closing pin 36. The closing pin 36 interacts with the locking pin 29 of the locking element 28. In the position shown in Figure 2, the closing cylinder 33, and with it the closing pin 36, is in a position of unlocking, in which the drawers 2, 3 can be opened. transfer of the closing cylinder 33 to a closing position, such as is represented in Figure 4, the entire column is displaced, against the spring force of the spring element 16, vertically down, against the first stop 15.

The operation of the blocking device of Extraction is explained in more detail below for the case from bottom 3 drawer. The bottom drawer 3 can be removed from the body 1 of the furniture in a displacement plane 37. By means of the Removing the lower drawer 3 the closing element 21 is tilted around the tilt axis 22 counterclockwise, since the pin element 24, which is connected to the drawer 3 bottom, crimp, in the inserted position of drawer 3 bottom, in the adjustment recess 23 of the closure element 21. After exceed a certain position during drawer removal 3 bottom, the pin element 24 slides from the recess of setting 23, the closure element 21 being then in the opening position During drawer removal 3 the element of pin 24 is supported, to swing the closing element 21, against a first adjustment surface 38, which is formed by the adjustment recess 23 and runs parallel to the axis of tilt 22. When moving the lower drawer 3, the spike element 24 rests against a second surface of adjustment 39 which is also formed by the recess of adjustment 23. The adjustment recess 23 is represented by the shape of a groove, which is incorporated in a plate 41, which forms the closing element 21. The groove forms a base surface 42, which connects the first adjustment surface 38 and the second adjustment surface 39 with each other, and therefore guarantees a rigid construction of the closure element 21. The plate 41 has further around the tilt axis 22 a circulatory edge 43 which forms the adjustment contour 25.

In the locked position of the closure element 21, the adjustment recess 23 is oriented parallel to the adjustment axis 19, the adjustment recess 23 having an opening 40 in the direction towards the first stop 15. In the opening position of the closure element 21 the adjustment recess 23 is oriented angularly with respect to the adjustment axis 19, so that the pin element 24 can exit the opening 40 of the recess
fit 23.

Since the adjustment contour 25 is formed in such a way that the distance from the contour of adjust 25 to the tilt axis 22, when the closing element 21 it is tilted counterclockwise, the first adjustment element 17 is displaced, against the spring force of the element of spring 16, vertically down, until it is in contact with the first stop 15. Since the clamping element 18 is supported, vertically above the column up against the second stop 30, the clamping element 18 does not move, when Tilt the closing element 21, along the adjustment axis 19. To guarantee defined tilting positions of the lock 21 in the locked position and in the open position, the adjustment contour 25 has a first resting point 44 for the holding the closure element 21 in its locked position and a second resting point 45 for securing the closure element 21 in its opening position.

After the drawer 3 has been removed, the device Extraction lock is in the position represented in the Figure 3. In this the path of the spring element 16 has been sold out so that all column elements are supported against in first stop 15 and against second stop 30. By consequently it is guaranteed that no other can be tilted closure element 21a. Thanks to this you are assured that you do not know you can remove any other drawer 2, when one of the drawers 3 is open. In addition, because of the limited path of the spring element 16, it is guaranteed that two drawers 2, 3 cannot be opened simultaneously.

To lock the locking device of extraction is moved, as explained above, the cylinder of close 33 to its closed position. This is possible only when with it all the drawers 2, 3 are in their inserted position and all closing elements 21, 21a They are in their locked position. By moving the closing cylinder 33 to the closing position all of the column is displaced vertically down, against the force of spring of the spring element 16, against the first stop 15. The Extraction locking device is found accordingly in the position represented in Figure 4. It is no longer possible tilt the closing elements 21, 21a, given that the column rests, on the one hand, against the stop 15 and, on the another, against the locking pin 36 and the path of the element of Spring 16 is sold out.

The closing position is explained with greater Detail for the case of lower drawer 3. In the closed position of the closing cylinder 33 the pin element 24 is located vertically at the same height as the tilt axis 22. This means that the vertical distance, seen in projection on the vertical axis 19, between the pin element 24 and the first stop 15 It is just as large as the vertical distance, seen in projection on the vertical axis 19, between the tilting axis 22 and the stop 15. This means that the pin element 24 and the shaft of Tilt 22 are arranged vertically at the same height. By consequently it is guaranteed that the tilting axis 22 and the pin element 24 are arranged in the plane of displacement from bottom 3 drawer. Therefore, when trying to remove the drawer 3 lower, there is no turning moment around the axis of tilt 22.

An alternative can be realized according to the invention, in which the pin element 24, seen in projection on the adjustment axis 19, adopt a greater distance from the first stop 15 than the tilt axis 22. This means, that the pin element 24 is arranged vertically higher than the tilt axis Therefore, when trying to remove drawer 3 lower, a turning moment is generated around the axis of tilting 22, which acts against the turning moment which is necessary for tilting the closing element 21 from the lock position to the open position. Therefore, a secure hold of the drawer 4 in the position is guaranteed inserted
