Definitions

the invention solves in particular the problem that, for example due to component tolerances, material changes or other influences, the movement of the synchronization element from an adjustment position back to the starting position does not take place or not completely, despite the presence of a retraction force such as e.g. B. by a restoring element such as a return spring.
a retraction force such as e.g. B. by a restoring element such as a return spring.
a restoring element such as a return spring.
a restoring element is advantageously provided, which acts on the synchronization element and provides a restoring force in order to bring the synchronization element into the starting position.
a restoring element provides a preferably permanently established restoring force in the direction of the starting position on the synchronization element.
the restoring element is preferably a restoring energy accumulator or a tensile force element such as a tension spring, for example a helical spring, which is preloaded or pulls in the closing direction and acts on the synchronization element.
a movement of the synchronization member in the closing direction leads to a rotational movement in a second direction of rotation of the connecting element, which z. B. is the case when resetting the synchronization element in the closing direction.
a piece of furniture 50 with a box-shaped furniture body 51 and a drawer 53 that is movably guided via guide means 52 is in figure 1 shown.
the drawer 53 comprises a drawer base 54, a drawer front 55, two opposite side walls 56 and a drawer rear wall 57.
the base plate 3 is covered by a cover element 20, the cover element 20 being one of the base plate 3 almost corresponding counter-plate forms, with which an interior of the device 1 is enclosed on both sides and on the circumferential narrow sides, with individual areas being open to the outside.
a receptacle in the base plate 3 for a second end of the power unit 4 can be seen.
the first end of the power unit 4 is connected to a connecting portion 24 of the pawl component 5 connected (see 4 ).
the pawl component 5 also has a guide member 25 which can preferably be moved permanently in the second guide area 23 of the guide track 8 .
the guide member 25 protrudes from the pawl component 5 and is preferably cylindrical or bolt-like.
Guide members 25 are preferably present on both sides of the latch component 5 and can be moved along the guide tracks 8 spaced apart in the width direction.
the guide element 25 can be moved along the second guide area 23 of the guide track 8 while being supported.
the latch component 5 also has a guide element 26 which is moved from the first guide area 22 into the second guide area 23 during an opening movement of the ejector 6 .
a hook section 27 of the latch component 5, which is located above the guide element 26 in the direction of the ejector 6, can be pivoted in the direction of the ejector 6.
the pawl component 5 also has a hooking contour 28 which can interact with the ejector 6 .
the hooking contour 28 is preferably aligned transversely to the opening and closing direction of the ejector 6 .
the ejector 6 has a depression 29 on an underside, which is directed towards the base plate 3 (see Fig. figure 5 ).
the recess 29 is preferably groove-shaped, with the longitudinal extension L of the recess 29 being aligned in the opening and closing direction of the ejector 6 .
the connection section 24 of the latch component 5 is preferably accommodated in the recess 29 .
the recess 29 has a surface which is formed in the width direction and height, with an edge contour 30 which can be coupled to and decoupled from the hooking contour 28 of the latch component 5 .
a stop element 31 is formed on the ejector 6 and interacts with the drawer 53 or a drawer rail of the guide means 52 . After unlocking the When the moving element 10 is loaded and held in a locked position, the ejector 6 moves in an opening movement of the moving element 10 and this, via the stop element 31, by the force of the charged power unit 4 and/or the energy store 7, moves the drawer 53 in the opening direction P1. During the closing movement P2, the drawer 53 or a section of the drawer rail presses against the stop element 31 of the ejector 6, as a result of which the moving element 10 or the ejector and thus the energy accumulator 7 acting on the ejector and the energy unit 4 are loaded.
the spring bar 15 is arranged in an arcuate section of the heart curve 16, whereby a movement of the spring bar 15 in the opening direction P1 is not possible because the synchronization plate 18 blocks this movement (see Fig. 6 ).
the device 1 has reached a zero position, and the drawer 53 rests in the closed position on the furniture body 51.
the synchronization plate 18 and the ejector 6 are also moved in the opening direction P1.
the drawer 53 is carried along or ejected.
the first opening position is then reached (see Fig. figure 9 ). In the first open position, the force accumulator 7 is discharged.
the hook portion 27 When pivoting the pawl component 5, the hook portion 27 can be deflected upwards in the direction of the ejector 6, wherein the hook section 27 engages behind an end contour 32 of the ejector 6 .
the power unit 4 can be discharged. This moves the pawl member 5 in the opening direction P1.
the ejector 6 is also moved in the opening direction P1 until the second opening position is reached (s. Figures 12 to 14 ).
the drawer 53 is moved in the opening direction P1 by the stop element 31 of the ejector 6 .
