    The present invention relates to a retraction device for retracting a movably mounted furniture part into the closed end position relative to a furniture body, comprising: a catch, which is releasably coupled to the movable furniture part and which is at least partially slidably mounted along a linear travel path, at least one spring device for Applying a force to the driver, wherein the spring device is tensioned via a spring holder separate from the driver, - a coupling device for movement coupling between driver and spring holder, wherein the coupling device the attachment point of the spring device on the spring holder when pulling out of the driver along a control cam with respect to the position of the traveling carrier.
    Furthermore, the invention relates to a drawer pull-out guide with a pull-in device of the type to be described as well as an arrangement with a drawer and with such a pull-in device.
    Feeding devices are used in particular with drawers or sliding doors, which are freely movable over a large part of their pull-out area and which is only detected towards the end of the closing movement by the catch of the catcher, pulled by spring force into the closed end position and held there with a predetermined closing force. Upon opening the movable furniture part, a user must first apply a force against the spring resistance of the retractor by pulling until the catch is decoupled from the movable furniture part after a predetermined distance and moved to a preloaded parking position in which the spring remains in a cocked standby position so that the movable furniture part at the next closing operation can be retracted again. For a user, the decoupling of the driver during the opening movement of the drawer often makes a jerky movement and a clicking sound noticeable, because due to the sudden spring breaking force, the drawer is free to move and accelerated due to the previously applied traction in the opening direction.
    Applicant's WO 2011/150432 A1 solves this problem by means of a spring holder separate from the driver, which is slidably guided along a control cam. The driver and the spring holder are connected to each other by a coupling device in the form of interlocking gears coupled to each other. When tensioning the spring device (i.e., when the movable furniture member is opened), the attachment point of the spring device on the spring retainer falls back from the position of the opening-runner, so that the movement of the attachment point of the spring device is slower than the movement of the follower. The charging of the spring device is thereby carried out with a reduced force, the unwanted spring break and an associated, excessive acceleration of the movable furniture part when uncoupling the driver can be prevented.
    Object of the present invention is to provide a collection device of the type mentioned in the introduction with reduced frictional forces and a more compact design.
    This is achieved according to the invention by the features of claim 1. Further advantageous embodiments of the invention are indicated in the dependent subclaims.
    According to the invention, it is thus provided that the coupling device comprises at least one two-armed lever with two lever ends, wherein the two-armed lever is pivotally mounted about an axis of rotation on the spring holder, wherein a first lever end of the two-armed lever is coupled to the carrier motion-coupled and wherein the second lever end of the two-armed lever at least Has guide element which is at least partially guided along the cam when pulling out of the driver.
    By the coupling device with the two-armed lever, a lever mechanism miteiner Kraftabsenkmechanik be realized, which has reduced frictional forces and reduced noise compared to a gear transmission. In addition to simpler to perform components, the proposed construction also offers the possibility of the levers of the coupling device - especially in the retracted position of the driver - nested in each other, whereby a very compact design of the feeder is feasible. By the particular shape and size of the two-armed lever or those of the control cam, the forces required to tension the spring device and the effective length of the tensioning path can be modified in many embodiments.
    Further details and advantages of the present invention will become apparent from the embodiments shown in the figures. It shows or show:

    2 a drawer extension guide with a collection device in a perspective view,
    3, the collection device seen in an exploded view from above,

    5a-5d, the clamping operation of the spring device in time sequences,

    Fig. 1 shows a piece of furniture 1 with a cabinet-shaped furniture body 2 and relatively movably mounted furniture parts 3 in the form of drawers 4. The drawers 4 each include a front panel 5, a drawer bottom 6, side walls 7 and a rear wall 8. Above the side walls 7 struts 9 are provided which extend between the front panel 5 and the rear wall 8 and to the
    Magnification of the receiving volume of the drawer 4 are provided. Zurverfahrbaren storage of the drawers 4 relative to the furniture body 2 drawer extension guides 10 are provided which each have a cabinet body 11 to be fixed to the cabinet body rail 11 and at least one to be connected to the drawer 4 pull-out rail 12 which is slidably mounted relative to the stationary body rail 11. Between the carcass rail 11 and the pull-out rail 12, an additional displaceable middle rail can be arranged, by means of which a full extension of the drawer 4 can be made possible. Such a full extension is present when the rear wall 8 in the fully extended state of the drawer 4 is approximately flush with the end face of the Möbelkorpus2.
    Fig. 2 shows the drawer pull-out guide 10 with a collection device 14 in a perspective view. By the collection device 14, the slidably mounted pull-out rail 12 is retractable towards the end of the closing movement by the force of a spring device 16 in the complete end position. For this purpose, the pull-out rail 12 usually has a coupling element (not shown) (in particular a pin projecting from the pull-out rail 12). This coupling element is detachably coupleable to a catch 18 of the retracting device 14 displaceably mounted relative to the housing 17 and can subsequently be retracted into the complete end position by the force of the spring device 16. The housing 17 of the retraction device 14 is preferably fixed to the body rail 11 and arranged in a space formed between the pull-out rail 12 and the mounting portion 13 of the body rail 11.
    Fig. 3 shows the collection device 14 in an exploded view from above. For sliding guidance of the driver 18, a linear travel path 19 is provided on the housing 17, to which a bent or bent portion 20 connects. The driver 18 has a notch 27, which is releasably coupled with a coupling element (in particular a pin) attached to the pull-out rail 12. In the full closed position of
    Drawer 4, the coupling element is in engagement with the notch 27. Beimmanuellen opening the drawer 4 is pulled over the coupling element and the driver 18 along the linear travel in the opening direction 35 (Fig. 5a-5d), whereby the spring device 16 is tensioned. After a predetermined travel distance, the driver 18 enters the bent portion 20 so that the driver 18 pivots, releases the coupling element of the pull-out rail 12, and then the drawer 4 can be moved further uncoupled in the opening direction 35. The cam 18 remains temporarily in the bent portion 20 in a tilted position, i. in a preloaded, self-locking locked standby position with the spring device 16 cocked. Upon closing the drawer 4, the coupling element disposed on the pull-out rail 12 may release the catch 18 from the biased standby position by entering the notch 27, whereupon the catch 18 (and thus the pull-out rail 12) is retractable to the full closed position by the force of the spring device 16.
    For tensioning the spring device 16, a coupling device 30 in the form of a lever mechanism is provided by which reduces the force required to tension the spring device 16, a sudden unwanted break of the spring force (ie, at the moment in which the driver 18 enters the bent portion 20 when opening and while the drawer 4 releases) and an associated, excessive acceleration of the drawer 4 in the opening direction is prevented. The spring device 16 can be tensioned via a spring holder 21 that is separate from the driver 18, wherein the attachment point 22 of the spring device 16 is connected to the spring holder 21. The spring holder 21 has a bearing 28 on which a two-armed lever 23 is pivotally mounted about an axis of rotation 25. On the two-armed lever 23, at least one guide element 24 is arranged on a lever end, which is displaceably guided along a control cam 33 (FIG. 4) of the housing 17. The other end of the lever two-armed lever 23 is connected via a hinge axis 36 with a, preferably arcuate, transmission lever 26. The other end of the transmission lever 26 is connected in a rotationally coupled manner to the driver 18 via a rotary bearing 29, wherein the rotary bearing 29 of the transmission lever 26 engages in an opening 31 of the driver 18. The first lever end and the second lever end of the two-armed lever 23 may have different lengths, and it is advantageous from a stand-by point of view when the guide element 24 is located at the longer lever end of the two-armed lever 23.
    4 shows the collection device 14 in an exploded view from below. The attachment point 22 of the spring device 16 is positively anchored in a recess 32 of the spring holder 21, the bearing 28 of the spring holder 21 serves for pivotally mounting the two-armed lever 23 about the rotation axis 25. The other end of the lever lever 23 of the two-armed lever 23 is articulated via the curved transmission lever 26 with the driver 18 connected. To guide the driver 18, a linear travel path 19 and an adjoining bent portion 20 are arranged or formed on the housing 17 of the collection device 14. The driver 18 has a guide device 34 in the form of a projection through which the driver 18 along the linear path 19 and along the curved portion 20 can be guided. Further, on the housing 17 a separate from the linear travel path 19 control cam 33 for sliding guide of the guide element 24 is formed. The cam 33 has a linearly extending portion and an adjoining curved portion corresponding to the last tensioning travel of the spring device 16. By the cooperation of the two-armed lever 23 with the curved portion of the control cam 33 can be achieved that in the last section of the tensioning path of the spring device 16 to the end of the tensioning path, the movement of the attachment point 22 of the spring device 16 on the spring holder 21 against the position of the traversing driver 18 falls back, so In the last tensioning path of the spring device 16, the movement of the attachment point 22 is slower than the movement of the follower 18. According to one embodiment, it may be provided that the length of the curved portion of the control cam 33 - with respect to the total length of the control cam 33 - amounts to at least one third of the total length of the control cam 33. Due to the length and shape of the control cam 33, the tensioning path and the force curve of the tensioning process can be modified in many different ways; for example, by a longer control curve 33 relative to the linear travel path 19, the force required for tensioning can also be reduced.
    5a-5d show the clamping operation of the spring device 16 in time sequences. Starting from the complete closed position according to FIG. 5a, in which the spring device 16 is largely relaxed, the driver 18 is moved along the linear movement path 19 in FIG Opening direction 35 is drawn, wherein the spring device 16 relative to the stationary spring base 15 (Fig. 2) is tensioned. In a first tensioning section ΔΧ1, there are approximately equal movement ratios between the mover 18 and the attachment point 22 of the spring device 16, i. the attachment point 22 moves at the same speed in the opening direction 35 as the catch 18. The two-armed lever 23 pivoted on the spring holder 21 is guided by the guide element 24 along the control curve 33, causing a movement of the attachment point 22 slowed in relation to the first clamping section ΔΧ1 in a second clamping section ΔΧ2 (5 b). As a result of the cooperation of the guide element 24 with the curved section of the control cam 33, the two-armed lever 23 is pivoted clockwise, so that in a third tensioning section ΔΧ3, movement of the fastening point 22 slower relative to the second tensioning section ΔΧ2 takes place relative to the driver 18 moving further in the opening direction 35. In Fig. 5d, the driver 18 assumes a tilted, self-locking locked ready position, in which the coupling between the movable furniture part 3 and the driver 18 is repealed, so that the movable furniture part 3 is further uncoupled in the opening direction 35 extendable. The clamping sections ΔΧ1, ΔΧ2 and ΔΧ3 thus bring about a continuous, slowed movement of the attachment point 22 relative to the carrier 18 moving in the opening direction 35, so that the spring device 16 is not tensioned to the maximum spring deflection. The
    Tensioning the spring device 16 thus requires less effort, with the transition region or load changes between the coupled and coupled positions of the follower 18 being significantly harmonized, i. derunerwünschte spring break and an associated unwanted acceleration of the movable furniture part 3 when uncoupling the driver 18von the drawer 4 can be prevented. By the reduction effected by the coupling device 30, also spring devices 16 with high spring force can be tensioned with a reduced expenditure of force.
    Fig. 6a shows the collection device 14 in a perspective view, wherein the spring device 16 can be tensioned relative to the stationary spring base 15.
    Fig. 6b shows the framed in Fig. 6a area in an enlarged view, wherein the driver 18 is in a retracted end position. The spring device 16 is connected via the fastening point 22 to the movable spring holder 21, on which the two-armed lever 23 is pivotably mounted about a rotation axis 25. The first lever end of the two-armed lever 23 is connected via a hinge axis 36 to a first end of the transmission lever 26, a second end of the transmission lever 26 is pivotally connected via a pivot bearing 29 with the driver 18. The second lever end of the two-armed lever 23 comprises a guide element 24, which is displaceably guided on a movement of the driver 18 along the control cam 33. It can be seen that in the retracted position of the driver 18, the attachment point 22, the hinge axis 36, the rotation axis 25 and the pivot bearing 29 are in a plan view substantially on a common line, which corresponds to the direction of action 37 of the spring device 16. By this alignment of the components, the frictional forces of the retraction device 14 can be significantly reduced.
    The compact design of the retraction device 14 can also be seen from the fact that in the retracted state of the driver 18 of the - along the longitudinal extent-arched transmission lever 26 engages the two-armed lever 23. Moreover, it can be provided that the spring holder 21, the two-armed
    Lever 23, the transmission lever 26 and the driver 18 - relative to the axis of rotation 25 - are arranged in the height direction from each other or overlapping. Due to this nested arrangement of the components, it is possible to extend a portion of the driver 18 toward the hinge axis 36 so that a total of extended portion of the driver 18 comes to the linear travel 19 to the plant. This also results in an improved non-tilting guidance of the driver 18 during a movement along the linear travel path 19.
    As spring devices 16, at least one coil spring can be used, which is preferably designed as tension springs. To apply a higher spring force, spring assemblies with two or more helical springs connected in parallel can also be used, which are all stretched the same way during the clamping process.
