Description

  The present invention relates to a catch fitting for a pull-out guide, and more particularly to a catch component for a pull-out guide of a drawer. Such a catch component comprises a switching curve on which the switching elements are mounted so as to be displaceable, each switching curve comprising a loop-like segment having a catch recess, the switching element being engageable with the catch recess by the force of a spring It is.

  European Patent Application Publication No. 1845821 discloses an opening / closing device for a drawer / withdrawal guide provided with a catch mechanism. When closing the drawer, the spring of the ejection device is biased and secured by the catch mechanism. To unlock the catch mechanism, the drawer is pressed against the spring force so that the switching element is moved from the engagement position within the switching curve and then moved to the open position by the spring. . The disadvantage of this open / close device is that the lock is released by pushing the drawer by hand. In particular, in the case of a wide drawer with opening and closing devices arranged on both sides of the drawer, on the one hand only the opening and closing device is unlocked and on the other hand the switching element can remain engaged. . As a result, the drawer cannot be opened, and further, the components (components) of the catch part are exposed to a strong force and may be damaged.

  Accordingly, it is an object of the present invention to provide a catch part for a movable furniture part that reliably unlocks a switching element.

  In order to achieve this object, a catch piece having the features of claim 1 is provided.

  According to the invention, the catch component comprises an initiator, by which the switching element can be moved from the catch recess. As a result, the unlocking of the switching element takes place directly via the starting element and not via a plurality of components that make the positioning of the switching element inaccurate as a result of tolerances. The starting element can displace the switching element into the loop segment of the switching curve by moving relative to the catch recess. In this case, the starting element and / or the catch recess can be configured to be movable as necessary to effect unlocking.

  In one embodiment, the starting element is activated by a switch, which can actuate the starting element and actuate the drive means in an electromechanical, electromagnetic or some other way. The switch can be arranged, for example, on the front panel or handle element of the drawer. It can also detect the movement by which the drawer is pushed by the sensor, which sends a signal to the controller to actuate the starting element, thereby simultaneously unlocking the switching elements on both sides of the drawer. For this purpose, the sensor may detect the movement of the slide rail or a component connected to the slide rail such that the starting element is operable. Based on optical, acoustic or other signals, a switch can be actuated by the controller.

  The starting element is mounted displaceably or pivotably on the switching curve in one embodiment. In one embodiment, the starting element is configured as a slider that is displaceably mounted on the switching curve along the receiving part of the component. The starting element is actuated by a driving means, which moves the starting element back to its initial position after the activation process. The starting element is configured to be pivotable, rotatable or displaceable. As various operating means or driving means, for example, driving means such as a lift magnet having a return device described below is suitable.

  In one embodiment, the starting element forms a stopper for the switching element in the initial position. Thereby, the switching element is moved directly when the start element moves. In this case, the starting element is arranged adjacent to the stationary protrusion of the switching curve provided with a catch recess.

  In order to unlock the switching element, the switching curve is fixed to the holder and the starting element is movable relative to the switching curve. Alternatively, the start element may be configured to be stationary, the switching curve may be movable relative to the start element, and both the start element and the switching curve may be movable in the opposite direction.

  In one embodiment, the starting element abuts the stopper in the opening direction and the switching curve is movable relative to the starting element under a tensile load in the opening direction. Thereby, if a pulling force is applied to the drawer in the opening direction, it can be an overload safety device. The starting element is then placed in a fixed position by a stopper, preferably by moving the switching curve in the opening direction of the drawer against the force of the spring to pretension the switching curve in the initial position, The lock is released. The force that causes overload is predefined by such a spring. While the switching element is unlocked by pulling force or overload, the movement of the switching curve and the starting element, i.e. the triggering by the movement in which the switching curve is moved in the opening direction and the starting element is moved in the opposite direction ) Can also be combined. For this purpose, a corresponding sensor for detecting a pulling force or pulling movement is provided, and a controller connected to the sensor may be provided for operating the starting element.

  The present invention will now be described in detail with reference to a few exemplary embodiments by reference to the accompanying drawings.

Figure 4 shows an enlarged view of a component having a starting element and the switching curve of the perspective view of Figure 3; A to D show views of the catch part during the unlocking of the switching element. A to D show views of a catch piece having a switch during unlocking of the switching element. The schematic circuit diagram for controlling the trigger of the catch component is shown. The exploded view of the modification of a catch component is shown.

  The extraction guide 1 includes a fixed guide rail 2 that can be attached to the furniture body. The slide rail 3 is attached to the guide rail 2 directly or via a central rail to which a projecting activator 17 is fixed. The actuator 17 can be connected to an entrainer 7 that is displaceable along the curved guide 5 of the housing 4. The housing 4 can be fixed to the guide rail 2.

  A further housing 6 of a spring element is fixed to the housing 4. The housing 6 may be engaged with a support body 65 (FIG. 3) integrally formed with the housing 4. The companion tool 7 is connected to a rod 60 accommodated in a dome-shaped receiving portion together with a thick spherical end section 61. The rod 60 is connected to a disk 62 opposite the end section 61 against which one end of the spring 63 abuts. The opposite end of the spring 63 is supported by the cover 64 of the housing 6.

  The companion tool 7 further includes a side arm 8 to which a connecting element 9 (see FIG. 4) is fixed. The connecting element 9 is connected to a switching element 10 configured as a metal wire with a bent end section 11. The bent end section 11 of the switching element 10 engages a switching curve 20 that is integrally formed with the component 18.

  The component 18 is detachably mounted on the groove-shaped receiving part 19 of the housing 4. In this case, the component 18 is pretensioned at the initial position by a spring 45 fixed to the holder 48 of the housing 4 at one spring end 46. A spring end 47 opposite to the spring 45 is fixed to the component 18. A base 12 is formed on a receiving part 19 of the housing 4 that is spaced from the component 18. As a result, the switching element 10 formed as a wire is movable between the base 12 and the component 18 via the switching curve 20 where the bent end section 11 engages the switching curve 20. Further, the base 12 prevents the bent end section 11 from coming off the switching curve 20.

  The switching element 10 can be unlocked from the engaged position by the starting element 30, which starting element is connected to the lift magnet 50 via a link 51. The lift magnet 50 has an internal return device.

  The functions of the switching curve 20 and the switching element 10 will be described in detail with reference to FIG.

  In the initial position, the drawer connected to the slide rail 3 is installed in the closed position, and the switching element 10 is held and engaged with the switching curve 20. For this purpose, the bent end section 11 is in the catch recess 26 of the switching camb 20 and is pushed into the catch recess 26 by the force of the spring 63 via the rod 60, the companion 7 and the further connecting element. It is. The switching curve 20 in the housing 18 is formed in a groove shape and includes a loop-shaped section 23.

  When the drawer is opened from this closed position (FIG. 4A), the switching element 10 is unlocked by pushing the drawer in the closed position towards the furniture body, and the bent end section 11 is pushed over the switching curve 20 and the slope ( By moving toward the run-in slope 28, the switching element 10 pivots and engages a receiving portion 27 that is offset with respect to the catch recess 26 (FIG. 4B). When the drawer 1 is released, the switching element 10 moves back to the loop section 23 of the switching curve 20 due to the force of the compression spring 63 until it moves into the outlet 32.

  During the closing operation of the drawer, the switching element 10 moves in the loop section 23 along the switching curve 20 and moves to a branch point 24 at a position adjacent to the grooved receiver 25. Thus, in the region of the branch point 24, the switching element 12 first moves within the protrusion 25 until the drawer front panel hits the furniture body. Next, the drawer 1 moves back toward the catch recess 26 when the force of the compression spring 63 is applied so as to reach the position shown in FIG. 4A.

  5 and 6 show a switching curve in which the switching element 10 is in a different position in order to unlock the switching element 10 and correspondingly open the pushing element that is otherwise attached to the extraction guide. A component 18 having 20 is shown. A starting element 30, which allows the switching element 10 to move from the catch recess 26, is displaceably mounted on the component 18.

  5A and 6A, the end section 11 of the switching element 10 is located in the catch recess 26 and the start element 30 is in the initial position.

  In order to unlock the switching element 10, the starting element 30 is moved so that the end section 11 of the switching element 10 moves from the catch recess 26 and is pressed against the driving ramp 28 as shown in FIG. 6B. , Displaced in the longitudinal direction of the component 18. As shown in FIG. 5C, while the starting element 30 is further displaced, the end section 11 is finally pushed out of the catch recess 26 and wraps around the tip 29 at the edge of the catch recess 26. Move into the loop section 23. Thereby, the starting element 30 is arranged in an offset state with respect to the driving slope 28 and preferably has a stopper 31 which is inclined in the direction of the tip 29.

  Next, the force of the spring 63 causes the switching element 10 to move along the looped section 23 of the switching element 20 in the direction of the opening (FIG. 6D).

  FIG. 7 shows the starting element 30 in detail. The starting element 30 is configured in a substantially plate shape and is displaceably attached to the receiving part 40 of the component 18 having the switching curve 20. The starting element 30 is provided with a step 35 on which a web is formed, and a stopper 31 for the end section 11 of the switching element 10 is formed at the end of the web. Furthermore, a protrusion 32 is provided on the starting element 30 guided in the substantially rectangular receiving part 40 of the component 18. A slide arm 34 projects laterally from the starting element 30 and extends through the open end section 41 of the concave receptacle 40. An opening 42 is formed in the receiving portion 40, and the web with the step 35 and the stopper 31 is introduced through the receiving portion 40. The starting element 30 can be displaced by electromechanical means or electromagnetic means connected to the slide arm 34. For this purpose, if necessary, a lift magnet 50 is provided which is excited via a controller. The controller can be connected to a sensor for detecting electrical, optical or acoustic pulses to effect unlocking.

  8A-8D show the catch piece during the unlocking of the switching element 10. In FIG. 8A, the starting element 30 is in the initial position and the switching element 10 is locked in the catch recess 26. For unlocking, the lift magnet 50 is excited and pushes the starting element 30 in the opening direction by means of a link 51 connected to the slide arm 34. As a result, the end section 11 of the switching element 10 moves from the catch recess 26 into the loop section 23 as shown in FIGS. 6A-6D.

  After switching off the excitation of the lift magnet 50, the starting element 30 moves under the action of a spring, for example by means of an internal return device in the form of a spring, and returns to its initial position. Next, the unlocked switching element 10 is moved in the opening direction by the force of the spring 63. In the end position, the companion device 7 waits in the end section of the curved track, and the slide rail 3 of the extraction guide can move independently of the companion device 7 in the opening direction. In such a release variant, the lift magnet can be attracted by an external switch, for example, so that no panel gap is required for release.

  When a tensile force is applied to the front panel of the drawer, the drawer can be displaced against the force of the spring 45 by mounting the component 18 displaceably. In such an overload situation, the starting element 30 remains stationary so that the relative movement between the component 18 and the switching element 10 results in the unlocking shown in FIGS. 6B and 6C in succession. Yes, a stopper for the switching element 10 in the opening direction can be formed.

  9A-9D show the catch part during unlocking, along with a switch 70 with a sensor 71 that can detect the movement of the component 18.

  Also, the unlocking of the switching element 10 due to the displacement (overload) of the component 18 can optionally be brought about by displacing the starting element 30 against the opening direction. For this purpose, the switch 70 can detect, by means of a sensor 71, the pulling movement or pulling force of the component 18 for which the controller activates the lift magnet 50. As a result, the starting element 30 is displaced by the lift magnet 50 (FIGS. 9B and 9C), unlocking the switching element 10 as already described with reference to FIGS. 6B and 6C. After unlocking, the component 18 is moved by the force of the spring 45 and the starting element 30 is moved back to the initial position by the internal return device (FIG. 9D).

  FIG. 10 shows a schematic circuit diagram of the controller. The switch 70 comprises a sensor and / or a sensing device and is connected via a controller to a lift magnet 50 that can move the starting element 30. The lift magnet 50 is connected to a power source 75 and can be excited to activate the starting element 30.

  FIG. 11 shows a variation of the catch piece where the same components are indicated with the same reference numbers as in the exemplary embodiment described above. Although a component 18 ′ having a switching curve is not displaceably attached to the housing 4, the component 18 ′ is provided with a head section 19 ′ at an end fixed to the holder 48 ′ of the housing 4. As a result, the component 18 is secured to the housing 4 by the steps of FIGS. 4 and 6 so that only the unlocking of the switching element 10 can occur.

  In the illustrated embodiment, the switch 70 may be connected to a mechanical, optical or acoustic sensor that provides unlocking of the switching element 10 depending on the application. Alternatively, for example, the drawer illumination may be switched on by the switch 70. Further, other functions may be performed by the switch 70.

  Instead of the lift magnet 50, another drive means for moving the starting element 30 can be provided, for example a pivoting magnet. The starting element 30 can be pivotally mounted rather than linear. The driving means for moving the starting element 30 is not limited to a lift magnet, and other adjustment driving means can be realized.

  The unlocking of several switching elements 10 can be performed simultaneously by a switch 70, for example by a switch 70 for the switching element 10 of the withdrawal guide on the opposite side of the drawer.
