EP1887172B1 - Device for locking a piece of furniture and furniture - Google Patents

Description

The invention relates to a device according to the preamble of claim 1 and a piece of furniture with such a device.

State of the art

Furniture with mutually movable furniture parts, for example, with a furniture body, in which a drawer or an extract is movably housed by means of a guide or cabinets with fittings for doors or flaps are known in different configurations. In addition, devices for such furniture in use, with which the movable furniture parts are locked in a closed position, for example, to prevent unwanted opening of the drawers, doors or the like by, for example, children. For this purpose, the movable furniture part in the locking position, for example, be opened only after a defined release action by a person again. Locking mechanisms are also known in so-called interchangeable locking systems, if, for example, only one of several drawers per body can always be opened. When the drawer is open, the other drawers are locked or kept closed. This can be realized for example with a vertical rod in the body, which with a pivotable unit per drawer
is provided, which can block the corresponding drawer.

For furniture with so-called touch-latch arrangements for drawers, doors or flaps, e.g. the furniture part located in the locking position can only be released again for opening when the movable furniture part is moved by a comparatively small distance, for example by pressing against the opening direction. In particular, when a piece of furniture is equipped with a locking device, it may happen that, for example, by jamming or tilting of relatively movable components or storage material, the lock can not be canceled. Also in electrically latched arrangements, e.g. in the event of a fault in the electrical supply, the unlocking must be blocked. In such cases, it can be caused by, for example, an improper action on the furniture to damage the furniture and its ancillary equipment or is thereafter no longer given the full functionality of the movement or the opening and closing mechanism.

The DE 90 04 923 U1 relates to a locking device for drawers.

Purpose and advantages of the invention

The object of the invention is to improve the aforementioned furniture or the operating options and in particular to provide a device with which disturbances or impairments of the function of movable furniture parts can be avoided.

This object is achieved by claim 1.

In the dependent claims advantageous developments of the invention are shown.

The invention is initially based on a device for locking a first furniture part in a closed position relative to a second furniture part, wherein the lock can be canceled via a triggering operation. An essential aspect of the invention is that release means are provided with which in the mounted state of the device on reaching a predetermined release force from the outside on the first furniture part in the opening direction unlocking the first furniture part is audible, if the lifting of the lock by the triggering operation not happened. Thus, the reliability of the locking device and the ease of use of inventively equipped furniture can be increased. In particular, unwanted damage and malfunction in locked and blocked movable furniture part can be excluded. Even in case of malfunction of the release mechanism of the lock or the guided movement of the first furniture part, the movable furniture part can be opened or operated at any time. The triggering process may e.g. a relative movement of the first furniture part to the second furniture part or an actuation of actuating means, for example a switch arrangement for a mechanical or electrical locking mechanism.

The release force is the force that must be applied from the outside to the first piece of furniture to the first piece of furniture, if this is blocked by the standard lock provided to reopen. In this case, preferably the default locking, which can not be canceled via the triggering process, bypassed, so to speak, and an alternative release mechanism is activated via the release force. The release force within the meaning of claim 1 may also be referred to as an emergency release force.

In addition to the emergency unlocking function, the proposed arrangement can also be used for opening when the release mechanism of the lock is not blocked. This can e.g. then be the case when the first furniture part can be opened by default only after pressing the first furniture part in the closing direction. With the proposed arrangement can thus be opened in normal operation by pulling on the first furniture part.

According to the invention the locking means are arranged on a receiving part and releasable for unlocking the first furniture part relative to the receiving part from a locking position. With the aid of a receiving part, the locking means can be simply mounted and securely fixed e.g. be positioned on a furniture body or on a movable furniture part.

According to the invention, the release means are designed so that upon reaching the predetermined release force, the unlocking of the first furniture part via a resettable release movement of the receiving part. A triggering movement e.g. by pivoting away or vertical or horizontal displacement of the receiving part is comparatively easy and space-saving set up. The release means may in particular also be such that they accomplish both the provision of the unlocking mechanism of the receiving part at a certain release force, as well as contribute to the fixed positioning of the receiving part in a basic position.

In principle, other mechanical release means can also be used or the release agents can also function magnetically or electrically.

In particular, can be with the device according to the invention in a jamming or tilting of the movable furniture part, which e.g. the locking position, for example, a touch-latch arrangement can not be canceled, or in case of failure of the unlocking function, for example, a child safety device or an interlocking system, the furniture part anyway open or use without interference. This is for example particularly advantageous if the movable furniture part must be opened immediately, e.g. to get at items that need to be accessible immediately. These can be, for example, important medicines or documents. So far, a failure of the unlocking of a movable furniture part from a closed position was countered only with appropriate time-consuming measures or it had to be at least partially destruction or damage to the furniture part accepted by force in purchasing.

According to the invention, the locking of the respective furniture part can be canceled with a predeterminable release force from the outside on the first furniture part. In this case, the specification of the force is selected such that the triggering force to be achieved can be applied by an adult, for example, without further ado. In addition, the force required for unlocking the first furniture part on the proposed release means is dimensioned so that the mechanical stresses occurring causes no damage to the furniture. It is also advantageously possible to protect the movable furniture part from unintentional or undesired opening, for example, by children, and thus to provide a child safety device to prevent access to the open furniture part. The necessary force or the release force to achieve the lifting of the lock, for example, be much higher than the force required for opening or unlocking of conventionally guided movable furniture parts.

Another advantage of the device according to the invention lies in the fact that the movable first furniture part can be unlocked or opened differently than used in normal operation. Thus, it is conceivable that, for example, in so-called touch-latch arrangements opening of the first furniture part in a locked closed position can be done by pressing against the opening direction as well as by pulling on the first furniture part in the opening direction.

Furthermore, it is advantageous that the release movement of the receiving part for releasing the lock is reset again, in particular at least partially or completely automatically, for example. via suitable spring mechanisms. Thus, the locking position can be unlocked according to the invention almost as often as desired. It when the receiving part or the locking means are returned by any special measures back to the original starting position can, in which a new emergency release according to the invention is possible is particularly advantageous. If it is not completely automatic, the reset may be e.g. in particular by a proper movement of the drawer or the like.

Preferably, the release means and / or the locking means are configured such that they can be reset with a movement of the first furniture part from an unlocked position to an initial position. Thus, for example, after a successful emergency unlocking a furniture part or an open drawer at their next move or the next operation, for example, the subsequent Weiteröff or next closing for the provision of the release means and / or the locking means can be used. Need both the Release means and the locking means are reset, they can be reset together with a eg closing movement or successively with, for example, two consecutive expiring movements of the first furniture part. In particular, the release means can be brought into their initial position, for example, in a first-time closing operation, wherein the locking means still remain in their position, eg still in a non-reset or unlocked position, for example relative to the release means. If the first furniture part is then moved somewhat or a comparatively short distance counter to the closing direction and then again in the closing direction, then the locking means can also be brought into their initial position in which they are reset or unlocked relative to the release means. This procedure is particularly advantageous for locking by means of touch-latch.

It is further proposed that the release means comprise a releasable latching connection, via which the receiving part is held in a latching position on a holding portion. A releasable latching connection allows in a simple and reliable way, the determination of the receiving part, for example, directly or indirectly to the second furniture part. Advantageously, detachable snap-in connections can be dimensioned or designed without any further such that the force for releasing the existing snap-in connections can be precisely determined or adjusted. In addition, locking connections can be comparatively space-saving and robust. In general, the receiving part or essential parts of the locking means is attached to the second or fixed furniture part. The locking means located on the receiving part, for example, cooperate with arranged on the movable furniture part further parts of the locking means so that the first furniture part coupled to the locking means on fixed furniture part can be locked or locked in a closed position. In principle, however, a reversal of the attachment of the receiving part or the locking means is conceivable. Thus, the receiving part may be attached to the movable or first furniture part with parts of the locking means.

In an advantageous embodiment of the subject invention, the release means comprise a resilient latching element which cooperates with a mating portion which fits to the latching element. To set up the releasable latching connection latching elements with suspension are particularly suitable because they require in particular little space and work reliably and robust. In addition, resilient components are suitable for automatic engagement or disengagement, when the locking element is guided past, for example, corresponding counterparts. As a resilient detent element, among other things, a detent pin may be used, e.g. is received in a recess and is movable over a spring positioned therein in its longitudinal direction. In addition, for example, a leg spring or the like may be used. The force or the connection stability, which can be realized with the resilient latching element or holds the receiving part in its latching position, can in each case be set in a stepped manner depending in particular on the configuration of the resilient latching element. In addition, the shape or the length of a locking bolt or the spring characteristic of a spring element which acts on the locking pin, be dimensioned differently.

It is also preferred that the release means comprise a latching element which moves with the movement of the receiving part along a slotted guide. The locking element can in addition to the function of holding the receiving part with a latching force in position or yield and to disengage, when the release force is reached, also serve to guide in the release movement of the receiving part of this in its movement. For example, it can be provided on the receiving part, a resilient locking pin, which leads by engaging in a corresponding guide on a component adjacent to the receiving part, the receiving part. If the receiving part is unlocked by the release force imposed from the outside, for example by a retraction or disengagement of the resilient locking bolt from a Verrastkontur in an adjacent component, the locking pin can enter a slotted guide and are moved along a defined path. With the release movement of the receiving part and the locking means arranged thereon are brought into a position in which the unlocking of the first furniture part is possible or is released and can be opened, for example. The locking means can remain in their locking position relative to the receiving part, but are spatially brought into a release position with this, in which the first furniture part is unlocked. A return movement of the receiving part in its initial position can be done with the help of the slotted guide and the latching element guided therein advantageous.

In an alternative arrangement, the release means has a connection with a shear element which can shear when the release force is reached. With a shear-off shear element, which is sheared off by the force from the outside on the first furniture part and the first furniture part or eg a drawer is unlocked, a particularly simple and inexpensive solution can be provided. Because only in comparatively rare case such as an emergency release then the destroyed shear element must be replaced by a new shear element to again create the conditions for a new release in the opening direction. In one In a simple case, the shearing element can be designed, for example, for a plug connection, wherein the shearing element can be a simple metal or plastic pin or the like, possibly with a predetermined breaking point. For example, depending on the shear element, the force can be adjusted at which the shearing occurs or the emergency release is triggered.

It is further particularly advantageous that the release means are designed such that the release force does not destroy the locking means and / or the receiving part acts. This can be avoided in the event of an emergency release damage or a negative impact on components. Since the secure unlatching of the receiving part from its locking position and thus the unlocking of the first furniture part takes place only when reaching or exceeding the predetermined force from the outside to the first furniture part, the release force lower external forces or tensile forces on the first furniture part on the locking means or The receiving part initiated or absorbed by the furniture.

An advantageous embodiment of the subject invention provides that the locking means comprise a catchable element which can be coupled to the first furniture part, which coupled with the first furniture part can reach a secured offset position in order to achieve the locking position. Such an arrangement is particularly reliable or robust. It is advantageous that the catch element only shortly before reaching the desired closed position of the first furniture part with this can get into a coupling position or is only temporarily coupled. Thus, the catching element arrangement can be comparatively easily arranged, for example, in a rear region of the piece of furniture, for example pivotable or otherwise displaceable. The catch element can with the first furniture part, once this in the proximity of the locking position comes, coupled or this be brought holding in a later releasable again locking position in which the first furniture part is closed, for example. The locking position can then be solved for example by counter-pressing against the first furniture part or in another way, for example by pressing an unlock switch.

It is particularly preferred that the locking means comprise a touch-latch arrangement. A touch-latch arrangement is particularly advantageous for arrangements with a high level of operating convenience. In addition, movable first furniture parts visually appealing without handles or handles and the like can be equipped, as they can be solved only by a slight counter-pressure, for example, against the front side of a locking position. Up to now, furniture with a touch-latch arrangement can not be easily opened if corresponding components become jammed or make unlocking impossible. Often then must be acted on the furniture so that damage to the furniture or on guides or parts of the touch-latch assembly is unavoidable to improperly unlock the first furniture part.

If a touch-latch arrangement is provided, in particular the locking means may be part of the touch-latch arrangement. If a touch-latch arrangement is used, according to the invention the first furniture part can be released both in the manner described by counter-pressing against the first furniture part from the locking position, as well as by pulling on the first furniture part or on the drawer in its opening direction. For the introduction of tensile forces on the first furniture part, any necessary measures are to be provided on this, for example, a handle bar, a handle or an overlapping protruding front end.

It is also conceivable to open the drawer with a suction cup or with auxiliary means which can be inserted or rotated laterally or behind the drawer front. Also, with several existing drawers to a jammed drawer above, below or laterally adjacent drawer can be opened so that you get access to the front of the jammed drawer and can open by pulling.

Vorteilhäfterweise the receiving part and the locking means are pivotable about a common axis. In this way, the overall arrangement can be further simplified and also requires relatively little space. Furthermore, for example, existing furniture with touch-latch arrangements with one or two pivotable locking levers can be particularly easily provided with the device according to the invention or optionally retrofitted with this device.

Starting from a device for locking a first furniture part in a closed position relative to a second furniture part, wherein the lock can be canceled via a triggering process, another essential aspect of the invention is that release means are provided with which in the mounted state of the device upon reaching a predetermined release force from the outside on the first furniture part in the opening direction an unlocking of the first furniture part is vornehmbar, wherein the release means comprise a releasable latching connection. A detachable latching connection can be set up in a simple or space-saving manner and is characterized in particular by a comparatively high level of reliability. In particular, advantageously, the arrangement explained above with the releasable latching connection, which engages in the event of an emergency release, can also be provided without the higher-level lock for locking purposes, for example by means of a touch-latch. Then it works the above designed as an emergency release arrangement as it were as the actual or sole locking of the first furniture part. Thus, for example, a kind of child safety can be realized, for example, in which an adult person can overcome the locking force of the releasable locking connection, but this is not readily possible for a child.

The invention also relates to a piece of furniture which has one of the above-mentioned devices. In this way, in particular furniture with extendable drawers, pull-outs or with doors or flaps can be designed so that the above-mentioned advantage can be realized.

FIG. 1 schematically shows a piece of furniture 1 with a furniture body 2 and a movable therein drawer 3. The arranged in the lower part of the furniture body 2 drawer 3 is shown in the open state and guided over two lateral guide rails movable in the furniture body 2, of which only a guide 4 in FIG. 1 is apparent. In addition, a guide 5 of two further guides, above the guide 4 in the furniture body 2 for receiving a further drawer, not shown, can be seen. The guides 4 and 5 comprise in particular a permanently attached to the furniture body 2 carcass rail, attached to the drawer 3 drawer rail and possibly acting between the carcass and the drawer rail middle rail. The drawer 3 is provided with a so-called touch-latch arrangement and therefore, for example, has no handle on a front panel 3a of the drawer 3. As will be explained in more detail later, the drawer 3 in trouble-free operation or in normal operation in its closed and locked with the touch-latch position in the furniture body 2 by an operator by pressing the front panel 3 a are unlocked. After unlocking the drawer 3 can be moved out, for example, via a charged energy storage or a presser. The charged energy storage or the Abdrücker, which are not shown here, for example, could be arranged at the front end of the drawer rail and collide against a stop on the carcass rail.

In FIG. 2 is another piece of furniture 6 with a furniture body 7 and a movable therein movable drawer 8 is shown. The piece of furniture 6 has a locking device 9 with a synchronization rod 10, a fixed or firmly bolted to the furniture body holding part 11 and a displaceable or releasable locking member 12, between which the synchronization rod 10 is positioned. The synchronization rod 10 synchronizes the pivoting movement of two catch levers 21 and 22 explained in more detail later.

FIG. 3 shows in perspective and in detail the locking device 9 and partially the rear end portions of two drawer rails 13 and 14, which are respectively secured to the drawer 8, not shown in the following figures. In addition, the furniture body 7 is not shown in the following figures. The drawer rail 13 has at its rear end via an adjustable coupling element 15 and the drawer rail 14 via a corresponding coupling element 16. The holding part 11 is fixed via a integrally formed thereon retaining plate 17 with Anschrauböffnungen fixed to the furniture body 7, for example on the inner wall or indirectly on the furniture body, for example, on a part of a carcass rail or a designated Anschraubwinkels fastened to the carcass rail. The locking member 12 is displaceable or pivotally mounted on a retaining plate 18 via a locking connection described in more detail below. The retaining plate 18 can likewise be fastened directly to the furniture body or, for example, to parts of a carcass rail. In FIG. 3 the unlocked position of the drawer 8 is shown, wherein the locking member 12 is locked in its non-pivoted position on the support plate 18.

In FIG. 4 is the arrangement according to FIG. 3 shown in a perspective view from behind. The coupling elements 15 and 16 each have an engaging roller 19 or 20, which can engage in the realization of a touch-latch arrangement respectively in pivotable catch lever 21 and 22, when the drawer 8 enters the closed position. FIGS. 3 and 4 shows the position of the locking devices 9 and the catch lever 21 and 22 in the unlocked position or when the drawer is in a non-closed position during normal operation. The engagement rollers 19, 20 or the catch levers 21, 22 and the synchronization rod 10 can, for example according to known touch-latch arrangements work.

If the drawer 8, for example, starting from the position according to FIGS. 3 and 4 pushed into the back of the body 7, move the drawer rails 13, 14 with the coupling elements 15, 16 in the direction of the spring-loaded catch lever 21, 22, that the engaging rollers 19, 20 engage in the catch lever 21, 22 and coupled with these in one locked or secured to the rear pivoted position of the catch lever 21, 22 reach (see FIG. 5 ). The catching levers 21, 22 are pivoted back and hold the engaging rollers 19, 20 in a locked position, whereby the corresponding drawer 8 is locked in the furniture body 7 in a closed position. If, for example, a jamming or tilting of components in the piece of furniture 6 causes a malfunction of the unlocking mechanism for the touch-latch arrangement, for example, so that the catch levers 21, 22 move out of the position according to FIG FIG. 5 not in the position according to the FIGS. 3 and 4 can pivot, an inventive emergency opening or emergency release mechanism can be triggered. After triggering the emergency release mechanism according to the invention, the arrangement according to FIG. 5 in an emergency unlocking position, in accordance with FIG. 6 is shown. The emergency release is effected by pulling on the drawer 8 to the front or in the opening direction. In this case, the engagement roller 20 acts on the catch lever 22, that the displaceable locking member 12 from its detent position (in accordance with FIG. 5 ) on the holding plate 18 disengages. In this case, the locking member 12 can be pivoted together with the catch lever 22 slightly forward and the catch lever 22 releases the engagement roller 20, which also the drawer 8 can be opened. The catch lever 22 is thus pivoted while retaining its latched relative position to the locking member 12 with this together forward, whereby the emergency release of the touch-latch Arrangement is possible. About the synchronization rod 10, the catch lever 21 is pivoted slightly forward according to the movement of the catch lever 22 which at the same time also the engagement roller 19 is released. For this purpose, the catch lever 21 spring-loaded forward without possibility of locking on the holding part 11 is pivotable.

In FIG. 7 is the holding plate 18 with the displaceable locking member 12 and the catch lever 22 in the locked position according to FIG. 5 shown. As in particular from FIG. 8 and FIG. 9 As can be seen, the catch lever 22 between a link part 12a and a locking part 12b of the locking member 12, which are fixedly connected to each other, pivotally received about an axis S. To achieve the emergency release position according to FIG. 6 must the locking member 12 and the locking member 12 b from the in FIGS. 7 and 8 be shown locked detent position. In this case, the latching position of the locking part 12, which is set up on the latching part 12 b via a resilient latching pin 23, has to be overcome. The locking pin 23 is accommodated in a bore 24 in the locking part 12 b projecting and housed therein resiliently via a coil spring 25. In the locked position of the locking part 12 of the Rastboplzen 23 engages in a round bore 26 of the support plate 18 and abuts it, for example, to an inner wall of the furniture body 7. The round bore 26 could in principle be configured as a recess in the support plate 18.

The catch lever 22 is guided by means of a displaceably received therein pin 28 formed as a guide groove 29 recesses in the guide part 12a on this and locked in a locking position in the locking member 12 at almost completely pivoted back position of the catch lever 22, which the representation according to FIG. 5 and 7 equivalent.

On the holding plate 18 to the flat side vertically arranged axle pin 30 is provided, on which the locking member 12 is pushed with the catch lever 22. A recorded on the axle 30 compression spring 31 is positioned so that in the unlocked position of the locking member 12 according to FIGS. 10 and 11 the locking pin 23 by the compression spring 31 in a curved formed slot 32 from a lower position according to FIG. 11 in an upper position (not shown) is urged, which is at the height of the round bore 26. In this position, the locking pin 23 when snapping back the drawer easily and safely snap back into the round hole 26. For this purpose, the next time driving back the drawer 8 the Eingreifrolle 19 or by the synchronization, the engagement roller 20 against abutment surfaces 21a and 22a of the catch 21 and 22. Here, the catch lever 22 is pressed together with the locking member 12 in its zurückschwwenkte position, so that the locking pin 23 from the upper position in the slot 32 can engage in the round bore 26. In this case, the locking pin 23 springs against the spring force of the coil spring 25 back briefly to bridge the intermediate region between the slot 32 and the round bore 26. Once the locking pin 23 is engaged in the circular bore 26 and the locking member 12 is thus moved back to its original position, is released by the further counterpressure of the engagement roller 20 against the contact surface 22 a of the catch lever 22 from its locked position relative to the locking member 12 and snaps back slightly in its initial position or unlocked position. In this position, the engagement roller 20 can again be caught by the catch lever 22 and coupled get into the lock on the next return of the drawer 8. During the triggering or unlocking movement of the locking part 12 with the locking lever 22 firmly locked in place, it can reach its maximum angle α (see FIG FIG. 11 ) are pivoted forwardly, wherein the locking pin 23 can get out of the round bore 26 into the lower position in the slot 32. The maximum pivoting or torsion angle α of the locking part 12 is determined by the position of the round bore 26 or the slot 32 or by the length of the slot 32 and can be set differently and is for example in the range of about 30 degrees. For secure reception of the locking part 12b in the normal position or in the position in which the locking pin 23 engages in the round bore 26, a corresponding U-shaped retaining tab 33 is formed on the support plate 18, to which the locking member 12b can come into contact.

The coupling elements 15 and 16 each include a dial 34 and 35, via which the engaging rollers 19 and 20 can be finely adjusted in position relative to the respective drawer rail 13 and 14 in the longitudinal direction thereof. This makes it possible in particular for each drawer rail 13 and 14, a depth adjustment, for example, of about +/- 3 mm, whereby an opening gap between a front edge of the furniture body 7 and the front of the drawer 8 is adjustable. This is necessary in particular for pushing in the drawer in a touch-latch arrangement or serves to compensate for any deviations from ideal mounting positions of the carcass rail or the drawer rail.

To synchronize the movement of the two catch levers 21 and 22, the synchronization rod 10 is received at corresponding pin portions, for example on a pin 36 (see FIG. 8 ) on the gate part 12 a, which is oriented in particular parallel to the axle pin 30. The synchronization rod 10 is also rotatably received on the axle pin 30 or on a correspondingly positioned axle pin on the catching lever 21.

About a fixing plate 27 on the axle 30, the contact pressure of the locking member 12 relative to the support plate 18 can be adjusted, which also affects the force which is necessary, the locking member 12 from its initial position in accordance FIG. 7 by pulling on the drawer 8 in the triggered position according to FIG. 10 bring to. In particular, the entire arrangement must be set so that other components, such as the catch lever 22 or the engagement roller 20 are not damaged.

In principle, a touch-latch arrangement can also be provided only on one side of a drawer. Then no synchronization bar would be necessary, e.g. with relatively narrow drawers.

Likewise, it would be conceivable that an emergency opening arrangement is present on each side of the drawer.

Also, the emergency opening according to the invention can be combined with a child safety device or with an interchangeable locking system.
