Description

State of the art:

Furniture with a movable furniture part, for example with a fitting or guide means on a furniture body pivotable door or flap or with a drawer or an excerpt are known in different configurations.

In such furniture so-called touch-latch arrangements can be used, wherein the furniture part is at least partially opened with a movably mounted opening element from a closed position on the furniture body. The movably mounted opening element is acted upon by a force storage in order to provide the necessary force for opening the furniture part can. For a next opening operation of the furniture part to be opened, the opening element must be in a standby position and secured against the action of the energy accumulator. From the standby position, the opening element moves out after a release under the force storage effect, in which case it opens the furniture part accordingly in contact with the furniture part. The unlocking of the opening element according to the touch-latch arrangement takes place in the closed position of the movable furniture part by pressing the furniture part towards the furniture body, ie in the closing direction.

Object and advantages of the invention:

The object of the present invention is to provide a device of the aforementioned type, which is improved in particular with regard to safety aspects and increased ease of use. In particular, after an accidental triggering of the touch-latch arrangement, a secure installation of the closed position of the furniture part should be possible.

This object is solved by the independent claims. In the dependent claims advantageous developments of the invention are shown.

The invention is initially based on a device which moves in a mounted state on a furniture on the furniture movably guided furniture part from a closed position in an opening direction of the furniture part, with a force storage device and a movably mounted opening element, after a release, by moving the furniture part in a closing direction and pressing against a Entsicherungsabschnitt, is moved out of a secure standby position under the action of the energy storage and thereby opens a contact portion of the opening element in contact with the furniture part of this, wherein the device is designed such that when opening the furniture part before reaching a completely open position of the furniture part of the contact between the contact portion of the opening member and the furniture part is canceled and that the opening element for a next opening operation of the furniture part in the Bereitschaftspos ition is located. The opening element may move back to the standby position immediately after losing the contact between the contact portion of the opening member and the furniture part or with a time offset. The moving back of the opening element can advantageously be coupled with the further opening movement of the movably guided furniture part. Particularly advantageous is the loading of the energy storage.

A first essential aspect of the invention is that the opening element, a displaceable support member is present, which is displaced via displacement depending on the movement of the opening member from a basic position in a manner that during a closing movement of the movably guided furniture part and a simultaneous impressions of the opening element in a case where the opening member has not been transferred to the standby position, the support member retains the furniture member so far that, in this process, the furniture member does not reach the unlocking portion in a maximum possible closed position. The pressing of the opening element in the direction of the standby position is effected by a contact of the furniture part with the opening element, so that the opening element is moved by the moving from the outside by a person furniture part. With or just before reaching the maximum possible closed position of the furniture part, the secured ready position of the opening element is achieved anyway.

A significant advantage lies in the fact that after an accidental release of the touch-latch mechanism, for example by abutting against a front side of the movably guided furniture part and thus a moving out of the furniture part from the closed position, by manually pressing the furniture part before the furniture part completely is open or if this is still relatively low, the closed state can be safely and quickly set up again. In this case, the opening element is brought back into its secure ready position with the return movement of the opening element. In addition, the energy storage is put back into the fully charged state without prior complete discharge. Advantageously, it is particularly excluded that in this process or immediately after reaching the secure standby position of the Opening element, the opening element is unlocked again while the energy storage unintentionally triggered and thus the opening process is set in motion.

This is achieved in that the support element is displaced so that it z. B. protrudes from an envelope surface or an edge contour of the opening element and can come into contact with an inner side of the furniture part. This is adjusted so that while the furniture body and thus the Entsicherungsabschnitt facing inside of the furniture part is held in the maximum possible closed position of the furniture part at a distance from the arming section of the opening element. An action on the Entsicherungsabschnitt is avoided in this situation. The displaceable support member thus acts temporarily, in a first phase of the opening process, so in particular in case of accidental triggering of the touch-latch mechanism, via the displacement means or depending on the movement of the opening element controlled as a spacer between the furniture part and the arming at a closing process. The support element is particularly in pivotal positions of the opening element, resulting in a comparatively small pivot angle of the closed position result in contact with the furniture part. Unaffected takes place in the opening direction of the opening required for contact between the opening element and the furniture part from a predetermined movement or pivoting position of the opening element between the contact portion and the furniture part. Only in a first movement or pivoting range of the opening element with respect to the secured ready position of the opening element is the support element the contacting part of the opening element. The movement or pivoting position from which contact of the support element with the furniture part no longer takes place and is then taken over by the contact section can be predetermined, for example, via an effective length dimension of the support element.

With the displaced protruding support element via the support element, the power transmission from the furniture part to the opening element when pressing the furniture part. The secured or in the fixed position located support member securely holds the opening element from acting on the Entsicherungsabschnitt.

Without the displaceable support member would be inevitably pressed so far during pressing of the furniture part by a person, the furniture part that a contact between the furniture part and the arming would take place, resulting in a triggering of the touch-latch mechanism. A triggering of the touch-latch mechanism is just not wanted in the considered operating case.

Further, it is advantageous that the displacement means are designed such that after reaching the maximum possible closed position and subsequent removal of a pressing action on the furniture part, the support element returns to its normal position. This ensures that the support element does not permanently prevent contact between the furniture part and the Entsicherungsabschnitt, which would override the touch-latch mechanism. Because in normal operation of the device, the triggering of the opening process by unlocking the opening element via the touch-latch mechanism is necessary. Upon reaching the maximum possible closed position of the furniture part, what the operator by z. B. can detect a stop position of the furniture part in the closing direction or by detecting the almost completely reached closed position of the furniture part, the operator will no longer press against the furniture part and let it off. Now advantageously the adjusting means come to the effect that with the no longer acting force from the outside by the operator and the effective force for secure retention of the support member in the displaced position no longer exists. With the pressing force of the operator, for example, a clamping mechanism for clamping the displacement means may be coupled, so that the displacement means hold the support member in the displaced position. By removing the clamping effect, an established restoring force can be effective, which allows the support member to return to its normal position, in which the support element is shifted back and can not come into contact with the furniture part.

It is also advantageous that the displacement means comprise a control element which is mounted in the opening element such that the position of the control element with respect to the support element and thus the position of the support member is dependent on a pivotal position of the opening element. Thus, the position of the control element and thus of the support element can be predefined as a function of the pivot position or pivot positions of the opening element. This is necessary because the support element in a closed position of the furniture part in the normal operation of the device is in a non-operative position and must be brought to the opening after the triggering of the touch-latch mechanism in an operative or projecting position. The storage of the control element in the opening element makes the interaction of control element and support element structurally advantageously possible.

Advantageously, the control element comprises a tension element whose end is fixed to a retaining element, wherein the retaining element moves in a slot which is formed on the opening element. Thus, the arrangement can be designed to save space. In particular tensile forces can be transmitted with a tension element. However, it is under the tension element to understand an element that can transmit compressive forces. In this respect, the tension element can be referred to by its function as a train-pressure element.

It is also advantageous that an end of the traction element opposite the gate-guided end acts on the movement of the supporting element. Thus, in particular with exactly one component depending on the movement of the opening element, the movement of the support element can be influenced or controlled.

Advantageously, the tension element is elastic, in particular a spring element. The tension element is in particular releasably received as a replacement part of the opening element. The tension element may be formed variable in length. In addition, can be realized with the elasticity, in particular a predetermined restoring force in an initial state in a previously made change in length.

In an advantageous modification of the subject invention, the support element cooperates with the tension element, that the force acting on the support element end of the tension element at a moved out of the ready position opening element and pressed against the opening element furniture part, ie in an externally effected closing operation, in its position on Support element is clamped by the support element. The support element is displaced from its normal position. Thus, the support member when closing the furniture part can be clamped in a displaced position held by the tension element acts on the support element accordingly. This in turn depends on the pivot position of the opening element. Thus, depending on the pivoting position of the opening element, the furniture part may be in contact with the support element or, if this is not protruding, otherwise with the contact section on the opening element which differs from the support element.

Advantageously, the tension element is guided in a channel. Thus, the tension element can not only be pulled, but also pushed. It can thus be transmitted in particular tensile and / or compressive forces with the elastic tension element. The tension element may be a helical spring with a rigid portion or bolt-like portion in the region of the end opposite the gate-guided end. The channel is open in the longitudinal direction end side and may be laterally tubular closed or partially open.

In an advantageous embodiment, the support element is a rocker arm whose tilting position is determined by the control element. With a rocker arm can be easily and safely realize different positions of the support element. The particular two-armed rocker arm can be displaced by pivoting or tilting in particular a few degrees from a sunk on the opening element or not active basic position in a projecting at the opening element contour or active position and back.

Further, it is advantageous that the backdrop moves on the opening element along the retaining element. The retaining element can thus stable fixed position, for example, be present on a fitting to a furniture body. The gate can be present on the movably mounted opening element, for example, as a bent designed slot whose width is tuned to an outer dimension of the retaining element. With the ends of the slide can be given relative to the furniture body with respect to opposite directions of movement of the opening element, if necessary, a stop for a maximum possible movement of the opening element.

Another essential aspect of the invention is that a first movably mounted lever and a second movably mounted lever is provided, wherein in the secured standby position of the opening element via the first lever, the ready position of the opening element is securable and wherein when pressed against the Entsicherungsabschnitt the second Lever is coupled via a coupling element with the first lever, so that in this case the opening element is Entsicherbar, wherein in a closing movement of the movably guided furniture part and a simultaneous depression of the opening element, for a case when the opening element has not been transferred to the standby position, the coupling element the two levers are not coupled in such a way that by pressing the furniture part against the arming section of the first lever unlocks the opening element. There are thus achieved according to the first essential aspect of the invention mentioned advantages. Thus, in particular, no unlocking of the immediately previously secured opening element takes place when the furniture part is pushed back immediately after the accidental partial opening.

This allows a structurally simple and compact and reliable acting Implement emergency function for a closing mechanism after an accidental triggering of the touch-latch mechanism. In the alternative emergency function, after reaching the maximum possible closed position of the furniture part and subsequent removal of a pressing action on the furniture part, the coupling means return to the coupled position between the two levers. Thus, the touch-latch mechanism is again in a functionally correct starting position and can be reactivated by pressing the furniture part in the closing direction at a next triggering operation.

The invention also relates to a piece of furniture with a device according to one of the aforementioned embodiments. The furniture comprises in particular a furniture body with a movably received furniture part such. As a flap, a door, a drawer or an excerpt.

This can be realized on a furniture, the advantages explained above.

In the 1 to 4 sections of the arrangement to illustrate the internal structure are shown partially transparent.

In different embodiments, the same reference numerals are sometimes used for corresponding components.

The 1 to 4 show schematically a first advantageous embodiment of the device according to the invention. This shows 1 a device 1 to open one at a furniture 3 movably guided furniture part 2 , here in the form of a closet door in its closed state of rest. The furniture part may also be a drawer or a different kind or designated, on a furniture movably arranged element.

Opening the furniture part 2 takes place, after an initiating, a locking mechanism 4 unlocking pressing the hinge-remote part of the cabinet door by means of the thus released, in a spring-like power storage 5 stored energy.

To charge a coil spring 6 of the energy store 5 is a charging mechanism 7 intended. The spiral spring 6 acts on an opening element for opening the furniture part 2 from according to 1 shown closed position of the furniture part 2 , The opening element is a lever pivotably mounted about a pivot point S1 8th formed, which at a first end via a hook-shaped power storage spring receptacle 9 with the force for opening the movable furniture part in its released state providing coil spring 6 connected is. A, based on the pivot axis S1 of the energy storage spring recording 9 , opposite second end of the lever 8th is the furniture part to be opened 2 assigned. A rotatable about a bearing axis S2 role 10 allows a comparatively very low-friction as well as low-noise contact when the lever 8th on the part of the furniture to be opened 2 moved along.

A force reducer 11 is exemplary here in the form of a relative to a basic element of the lever 8th and / or its pivot point S1 formed along the two directions of the double arrow P1 slidably mounted lever-part element. For varying the force application point of the energy storage spring recording 9 is at the relevant lever end a longitudinal slot 12 intended.

Another possibility for influencing the distance in the closed state of rest between furniture and the movably guided, to be opened by the device furniture part 2 and / or for adapting the device 1 at a corresponding predetermined distance can by a positioning means, here for example in the form of an eccentric screw 13 , be provided. By means of such a positioning means, the release position for releasing the door element to be opened to the required width of the front gap between the furniture 3 and the furniture part 2 be set.

By means of the positioning means can be a positioning of furniture part unlocking means 14 opposite the furniture 3 and / or to a base plate 15 , on the parts of the device 1 are recorded, realized and thus their trigger point according to the directions of the two double arrows P2 and P3 are varied. The positioning means may deviate from the eccentric version with the eccentric screw 13 for example, in the form of a relative to a fixing point displaced Long hole or another, corresponding execution be realized.

The locking mechanism 4 and / or the furniture part unlocking means 14 comprise in the embodiment shown here two pivotally mounted in each case via a pivot axis S3 and S4 and via a connecting lever 18 coupled pivoting lever 16 and 17 , The first pivot lever 16 has two aligned approximately in the same direction and with a two knee sections having intermediate piece connected, approximately rectilinear lever ends. As a Entsicherungsabschnitt the device 1 serving front end of the first lever end 16a is the furniture part to be opened 2 assigned, starting from 1 by pressing the furniture part 2 in the direction of the furniture 3 and the consequent pivoting of the pivot lever 16 over the pivot point S3 and parallelogram over the connecting lever 18 the second pivot lever 17 is controlled. Here comes a hook-shaped end 17a of the pivot lever 17 out of engagement with an associated, complementary, here exemplary pin-shaped locking element 19 on the lever 8th ,

The device 1 to open the furniture 3 movably guided furniture part 2 is hereby unlocked. It can open the closet door after the release of the locking mechanism 4 or for the actuation of the furniture part unlocking means 14 open the applied force according to the arrow P4. The lever pivots 8th from the in 1 illustrated standby or locking position about the pivot axis S1 under the spring action of the coil spring 6 , where the role 10 inside against the furniture part 2 suppressed.

For returning the parallelogram pivotable lever mechanism with the pivot levers 16 . 17 and the connection lever 18 can be a means of return 20 , designed here by way of example as a spiral tension spring may be provided. damping elements 21 . 22 and 23 can further increase the ease of use for the two pivot levers 16 and 17 and the locking element 19 be provided. As materials of the damping elements z. B. elastic sheaths of the relevant stop elements use such. As O-rings, rubber or plastic buffer or the like.

The charging mechanism 7 for the energy storage 5 Here is an example in the form of a hinge 24 realized. It includes a furniture part adapter 25 , one about a camp 26 movably coupled connector 27 , one about another camp 28 coupled with tensioning lever 29 and a subsequent, in a pivot bearing 30 swiveling control cam 31 with a flank 31a , The tension lever 29 with the control cam 31 velvet flank 31a turns when opening the furniture part 2 in the direction of arrow P5 around the pivot bearing 30 ,

A third end 32 of the lever 8th forms the complementary control to the hinge 24 the device 1 off and both together, together with the energy storage spring recording 9 of the pivotable about the pivot axis S1 lever 8th the charging mechanism 7 for the energy storage 5 , This charging mechanism 7 will be effective when the furniture part 2 regular from its slightly open position after unlocking the unlocking mechanism or the activation of the furniture part unlocking means 14 resulting opening position is opened further (not shown). For this, the third end pivots 32 of the unlocked pivot lever 8th according to the arrow P6 about the pivot point S1 until the blocking of the pivoting movement against the control cam 31 , Preferably, the geometries of the individual sub-elements of the device 1 be designed so that the energy storage 5 still has a slight bias in this position. This allows all elements of the device involved 1 be stabilized in their respective working position.

By means of a stored in a bearing axis L role 33 can be a virtually frictionless control flow and thus an improved guidance of the movement of the third end 32 of the lever 8th upon application of a corresponding force by the control cam 31 be achieved.

Upon further opening of the furniture part 2 in the direction of the arrow P4 over the in 2 shown position (not shown) moves the role 33 continue along the flank 31a in accordance with the straight control cam in the direction of the arrow P6 through the hinge 24 controlled cam movement in the direction of arrow P5. This will be the lever 8th with its second end according to the arrow P7 in the direction of the closing state of the device 1 emotional.

By pivoting the lever 8th also pivots its first end or the energy storage spring recording 9 against the tensile force of the energy storage 5 and loads it to prepare for the next opening operation for the furniture part 2 on until the locking hook at the end 17a of the pivot lever 17 after a Ausschwenkvorgang by pressing the locking element 19 against a convexly rounded end-side leading edge outside at the end 17a returns to its original locking position and with the locking element 19 locks.

The locking parts or the pivot lever 17 and the locking element 19 thus form in this embodiment force storage unloading lock. As a result, the furniture part to be opened 2 from this swivel position or with just before latched lever 8th be moved completely freely. Both in a further opening direction as well as in the closing direction, to the regular intended closing state of the furniture part 2 with a forming "front gap" a (see 1 ) between a front side of the furniture 3 and an inside of the furniture part 2 , The control sock 31 can do this with a flank 31b on the roll 33 , touching or without contact, in which you from the pivot bearing 30 move along predetermined movement curve.

After fixation of the recharged energy storage 5 by the energy storage-unloading locking means, here in the form of the hook-shaped lock 17a . 19 , is the device trip end or the lever end 16a fitting to the inside of the furniture part 2 and the lever 8th again in its rest position and thus for a triggering of the next opening operation by pressing against the direction of the arrow P4 on an outside 2a of the furniture part 2 operational.

The 3 and 4 show in practice frequently occurring operating situations, which inadvertently by pressing on the outside 2a of the furniture part 2 the furniture part unlocking means 14 have been activated, so the lever 8th as previously described under the effect of the energy storage 5 something swings out while the furniture part 2 in the opening direction according to arrow P4 in 2 emotional. This is where the invention begins, according to which a user immediately upon noticing the accidental opening on the furniture part 2 can act, so that the furniture part 2 easily brought back into the closed position with fully charged energy storage.

In this case, the possibility is provided according to the invention, immediately after the accidental release of the device 1 or unlocking the lever 8th what z. B. by an abutment outside the furniture part 2 can be done by a repeated or stronger counterpressure on the furniture part 2 the device back in accordance with 1 shown situation with the standby position of the lever 8th bring to. When pressing on the outside 2a of the furniture part 2 according to arrow P8 (see 3 ) becomes the lever 8th pivoted back according to arrow P9 and brought into its standby or locking position. To avoid the furniture part 2 in this pressing and pivoting of the lever 8th the furniture part unlocking means 14 activated or an inside 2 B of the furniture part 2 against the end of the lever 16a presses, according to the invention, a safety or emergency charging mechanism is present. This includes a tilting or pivoting lever 35 trained support element on the lever 8th , The swivel lever 35 is designed as a two-armed lever and a pivot bearing 36 on the lever 8th limited tilted stored. In addition, as a train-pressure element 37 configured Versetzmittel present, which depends on the pivotal movement of the lever 8th from a basic position, which in 1 shown is displaceable. The tensile pressure element 37 For example, is designed as an elastic spring element, the fixed position at one end to the base plate 15 is fixed. For this purpose, for example, a bearing pin 38 at the base plate 15 present in a recess at one end of the pull-push element 37 intervenes. The bearing pin 38 penetrates a backdrop-like curved extending slot 38a in the lever 8th ,

At the other end of the train-pressure element 37 is a rigid clamping bolt section 39 educated. In addition, the train-pressure element 37 longitudinally displaceable in a slotted guide 40 in the lever 8th protected.

Depending on or with the pivoting of the lever 8th in the opening direction from the starting position according to 1 For example, after an accidental knocking on the furniture part 2 , the pull-push element moves 37 relative to the lever 8th in the slide tour 40 so that the clamping bolt section 39 according to arrow P0 in 3 in the direction of the pivot lever 35 is moved and on this at an inner free end portion 35b acts so that the pivot lever 35 with its to the inner end section 35b opposite free outer end with a support portion 35a so overhanging the lever 8th forms that the support section 35a in contact with the inside 2 B of the furniture part 2 according to 3 arrives, especially if the furniture part 2 in the direction of arrow P8 by pushing in the direction of the lever 8th is moved. This corresponds in particular to the case that the operator immediately after the accidental abutment of the furniture part 2 this noticed and the furniture part 2 closes again.

Here is the support section 35a so shifted on the lever 8th and on one of the inside 2 B facing outside 8a overlapping that contact the inside 2 B with the role 10 not taking place ( 3 ), but the inside 2 B against the support section 35a pushes and thus according to arrow P10 ( 4 ) the inner end portion 35b of the pivot lever 35 against the clamping bolt section 39 pushes and this can not retreat against the direction of the arrow P0, what would happen if the lever 8th without pressing the furniture part 2 against the support section 35a or moves in normal operation in direction P9.

This causes the train-pressure element 37 not back to its original relative position to the lever 8th it will move when pivoting the lever 8th elastically extended and thereby preloaded. On further pivoting is with reaching the Verrastungsposition of the lever 8th over the locking mechanism 4 the energy storage 5 properly loaded again, something 4 shows. The furniture part 2 or the lever 8th can not continue to the furniture 3 push in, because the role 10 against the pivot lever 16 or the bearing pin 38 in the slot 38a strikes. However, it remains due to the supernatant of the support section 35a the inside 2 B of the furniture part 2 spaced from the arming section or the lever end 16a of the pivot lever 16 , This allows the furniture part 2 only up to the according 4 shown position are pressed. The inside 2 B remains at distance b from the end of the lever 16a spaced.

Is based on 4 then a pressing force on the furniture part 2 taken away, also the clamping action of the end portion 35b on the clamping bolt section 39 lifted and the under elastic prestressing train-pressure element 37 extends in the direction of the fixed position end on the bearing pin 38 together and with its clamping bolt section 39 back. This lacks an abutment for the end section 35b so that the pivot lever 35 again in its non-protruding orientation on the lever 8th according to 1 arrives.

Subsequently, under slight bias of the device 1 the inside 2 B by the distance b or by a few millimeters in the direction of the furniture 3 offset until contact with the end of the lever 16a ,

One of the basic principle to the device according to 1 to 4 comparable alternative arrangement shows 5 , The device according to 5 differs only in the locking mechanism 4 and the furniture part unlocking means 14 , The furniture part unlocking means 14 comprise one by means of a compression spring 42 sprung and relative to the furniture 3 linearly displaceable release lever 41 that with an intermediate lever 43 is connected, which in turn on a pivot lever 44 acts, which is pivotable about a pivot axis S4. To cancel the locking mechanism 4 is when pressing the furniture part 2 the pivot lever 44 so swung that a pen 45 at the front of the swivel lever 44 from a locking contour 46 on the lever 8th is released and the unlocked or unlocked lever 8th pivots under the action of the coil spring 6 in the direction of the furniture part 2 out and open this.

Other elements including emergency function are according to the embodiment of the 1 to 4 educated.

Another inventive and highly schematically illustrated device 1 on a piece of furniture 3 with a movably received furniture part 2 show the 6 to 10 , This comprises a pivoting designed as opening element Auswerfarm 50 with a roll 53 that has a pivot 51 on a base plate 52 is included. In addition, a trigger mechanism is realized, which has a pivotable tentacle 54 which has a pivot bearing 55 at the base plate 52 is received, and another pivotable release arm 56 which has a pivot bearing 57 also on the base plate 52 is available. About one between the tentacle 54 and the trigger arm 56 clamped compression spring 58 are the tentacle 54 and the trigger arm 56 coupled. Furthermore, a leaf spring 59 firmly on the tentacle 54 arranged, which has a recording 60 on the trigger arm 56 in the basic position according to 6 releasably attacks.

The ejection arm 50 and the tentacle 54 are according to 6 via a locking mechanism 4 in the basic position shown according to the starting position 1 with the ready position of the ejection arm 50 shown. Here is the leaf spring 59 in coupling position on the release arm 56 latched. The compression spring 58 presses the tentacle 54 and the trigger arm 56 apart and holds them in a basic orientation with locked ejection 50 ,

Via an engageable pressure pin 61 can by pressing on the furniture part 2 in the direction of arrow P10 on the release arm 56 be acted upon (see 7 ). The leaf spring bends 59 so through, that the tentacle 54 by pivoting in the clockwise direction the Auswerfarm 50 unlocked.

The other elements with a force storage or a hinge are not shown, which then the Auswerfarm 50 Swing out in the opening direction.

Will according to the emergency function the furniture part 2 pressed again in the closing direction ( 8th ), the tentacle hurries 54 by interaction of a latching section 62 at the ejection arm 50 so before that the leaf spring 59 out of engagement with the release arm 56 arrives. The leaf spring 59 is thus decoupled from the release arm 56 , In addition, the release arm presses 56 the leaf spring 59 so away that the end free leaf spring 59 initially not in engagement with the recording 60 on the trigger arm 56 arrives. After locking or locking the tentacle 54 with the cooperation of the compression spring 58 becomes the leaf spring 59 on further impressions of the furniture part 2 and thus a corresponding pivoting of the triggering arm 56 pushed into a tense position ( 10 ). After removal of the pressure effect from the outside on the furniture part 2 snaps the leaf spring 59 after dodging the release arm 56 down to the basic position with its free end back into the receptacle 60 in the cocked position between the tentacle 54 and the trigger arm 56 according to the basic position 6 ,

The same principle of operation prevails when, conversely, the leaf spring 59 on the trigger arm 56 firmly picked up and on the tentacle 54 releasably attacks.
