Definitions

  • the invention relates to a self-retracting device for a furniture part that can be pulled out of a furniture body in a pull-out direction by means of a pull-out guide and inserted into the furniture body against the pull-out direction, comprising a slide which is displaceably mounted by a base body from a basic position to a waiting position, and a slide into the basic position acting pull-in spring, whereby the carriage can be moved from the basic position to the waiting position by coupling with a driver which can be moved in the pull-out direction against the force exerted by the pull-in spring, in which the driver can be uncoupled from the slide and in which the slide is held against the force of the pull-in spring is, and a damper unit for damping the displacement of the carriage from the waiting position to the home position, which has a part movable in and against the extension direction, which is coupled to the carriage.
  • Such self-retracting devices are usually integrated into pull-out guides.
  • a self-retracting device of this type The damper unit used to dampen the retraction movement is formed by a pneumatic piston-cylinder unit. Damper units designed in a different way have already been used in self-retracting devices, for example rotation dampers. So that the pull-out furniture part can be pulled out starting from When the pull-out furniture part is fully pushed in, it is not hindered by the damper unit, the damper unit preferably only acts in the direction of insertion.
  • the retraction spring on a lever which is pivotally mounted relative to the carriage and relative to the base body of the self-retracting device.
  • the axis of rotation formed relative to the base body is displaceable relative to the lever or relative to the base body, in particular by a link arranged in the lever or in the base body, into which a guide pin forming the pivot axis engages.
  • the course of the force exerted on the slide by the retraction spring The pull-in force can be adjusted depending on the position of the carriage.
  • the object of the invention is to provide an advantageous self-retracting device of the type mentioned, which has a relatively short overall length with a relatively long retraction path. According to the invention, this is achieved by a self-retracting device with the features of claim 1.
  • the carriage is coupled to the movable part of the damper unit via an arm.
  • This arm can be pivoted about a first pivot axis relative to the carriage and about a second pivot axis relative to the damper unit.
  • the first pivot axis is displaceable relative to the arm or the carriage and/or the second pivot axis is displaceable relative to the arm or the movable part of the damper unit.
  • the arm is guided by the base body between a rear end position, which the arm assumes in the basic position of the carriage, and a front end position, which the arm assumes in the waiting position of the carriage.
  • the distance by which the carriage is displaced is greater than the distance by which the movable part of the damper unit is displaced, preferably by more than twice. It is therefore over the end section of the retraction path from the damper unit Damping force exerted on the carriage is reduced, preferably to less than half.
  • Freewheeling of the damper in the end section of the movement of the carriage from the waiting position to the basic position can thereby be reduced or preferably eliminated entirely.
  • the required length of the damper can thereby be shortened.
  • the damper is preferably designed in the form of a piston-cylinder unit, in particular a pneumatically acting one.
  • the base body advantageously has a slot into which at least one guide pin of the arm engages.
  • at least one guide pin of the arm engages this link to guide the combined displacement and rotation of the arm.
  • an elongated guide pin of the arm could also be provided, which engages in the link of the base body, or two links of the base body could be provided, into which a respective guide pin of the arm engages.
  • an advantageous embodiment of the invention provides that the pull-in spring engages a spring lever which can be pivoted relative to the base body about a first axis of rotation and relative to the carriage about a second axis of rotation, the first axis of rotation being displaceable relative to the base body or relative to the spring lever.
  • the translation of the spring force onto the slide can therefore be modified via the retraction path of the slide.
  • the carriage has a tilting part which is pivotably mounted about a tilting axis between an engagement position and a release position.
  • the tilting part assumes the engaged position and the driver is coupled to the tilting part.
  • the driver can engage in a recess in the tilting part that is in the engaged position.
  • the driver could also have a recess into which a projection of the tilting part engages.
  • the tilting part is tilted into the release position when the carriage is in the waiting position. This enables the driver to be decoupled from the tilting part, for example by moving the driver out of the recess in the tilting part, and the tilting part is held by the base body against displacement against the pull-out direction.
  • the tilting part also forms a holding device for holding the carriage in the waiting position when the carriage is uncoupled from the driver.
  • a holding device for holding the carriage in the waiting position when the carriage is uncoupled from the driver.
  • Other designs of such a holding device are possible and known.
  • the carriage itself could be tilted about an axis perpendicular to the pull-out direction (through a correspondingly curved guide of the base body), whereby the driver can also move out of a recess in the carriage, and the carriage directly by contact be held on a retaining surface of the base body against displacement against the pull-out direction.
  • a first embodiment of the invention is in the Fig. 1 to 28 shown.
  • the self-retracting device is integrated into a pull-out guide, which in the exemplary embodiment shown includes a body rail 1, a middle rail 2 and a pull-out rail 3.
  • the pull-out guide is designed here in the manner of a differential pull-out guide, in which the middle rail 2 travels half the distance of the pull-out rail 3 when it is pulled out and pushed in.
  • all rollers can be arranged on the middle rail 2.
  • the pull-out guide can be designed in a conventional manner and the arrangement of the rollers and their functionality do not need to be explained in more detail here.
  • a self-retracting device can also be integrated into other types of pull-out guides, for example in a pull-out guide which only has a body rail and a pull-out rail.
  • the pull-out rail 3 is pulled out, starting from the fully inserted state, in a pull-out direction 4, and the pull-out rail 3 is pushed in counter to the pull-out direction 4.
  • the self-retracting device has a base body 5, of which a carriage 6 parallel to the pull-out direction 4 between a basic position ( Fig. 7 , 9 , 13 , 17 , 21 and 25 ) and a waiting position ( Fig. 8 , 10 , 16 , 20 , 24 and 28 ) is mounted displaceably.
  • the carriage 6 For the displaceable guidance of the carriage 6, it has grooves 7 on both sides, into which mutually directed webs 8 of the base body 5, which run parallel to the pull-out direction 4, engage.
  • the carriage 6 could also have projecting guide pins for displaceable guidance on the base body 5, which engage in slots in the base body, for example in the form of elongated holes.

  • a damper unit 22 is used to dampen the displacement of the carriage 6 from the waiting position to the basic position.
  • This has, for example, a hydraulically pneumatically acting piston-cylinder unit 22a as a damper.
  • the cylinder is immovably connected to the base body 5.
  • the piston rod is connected to a movable part 22b of the damper unit, which is guided by the base body 5 so that it can move parallel to the pull-out direction 4. Only the movement of the movable part 22b against the pull-out direction is dampened by the piston-cylinder unit 22a, while the movement of the movable part 22b in the opposite direction is undamped.
  • dampers which have a freewheel in a direction of movement, in particular pneumatically acting, are known.
  • a kinematically reversed arrangement of the piston-cylinder unit is also conceivable and possible, i.e. the piston rod is immovable relative to the base body 5 and the cylinder is displaceable and is immovably connected to a movable part of the damper unit.
  • the movable part 22b of the damper unit 22 is coupled to the carriage 6 via an arm 23.
  • the second pivot axis 5 can be formed, for example, as shown, by an axle journal 26 of the movable part 22b of the damper unit 22, which engages in an axle recess 27 of the arm 23.

  • the first and second pivot axes 24, 25, which are parallel to one another, are perpendicular to the pull-out direction 4 and are preferably horizontal.
  • the arm 23 is movably mounted by the base body 5 between a rear end position and a front end position.
  • the arm 23 occupies the rear end position in the basic position of the carriage 6.

  • the base body 5 has a link 30, into which the first and second guide pins 31, 32 of the arm 23 engage.

  • the driver 33 pulls the carriage 6 via the tilting part 9, starting from its basic position in the pull-out direction 4, against the force of the pull-in spring 13, which is transmitted to the carriage 6 via the spring lever 14, in the direction of its waiting position.
  • the tilting part 9 pivots about the tilting axis 10 from its engaged position into the release position. In the release position, the driver 33 can extend out of the recess 9a of the tilting part 9.
  • a retaining section 9b of the tilting part 9 rests on a retaining surface 5a of the base body.

In the last section of the displacement of the carriage 6, before it reaches the waiting position, the grooves 9d extend from the front ends of the webs 8, so that the tilting part 9 can be pivoted from the engaged position into the release position.
  • the tilting part 9 is pivoted from the release position into the engagement position, in which the driver 33 engages in the recess 9a of the tilting part 9.
  • the displacement of the carriage 6 in the direction of its basic position is thereby released and the pull-in spring 13 pulls the carriage 6 and with it the driver 33 against the pull-out direction 4 until the carriage 6 reaches the basic position.
  • This movement of the carriage over the retraction path extending from the waiting position to the basic position is dampened by the damper unit 22.
  • the arm 23 When the carriage 6 is moved from the waiting position towards the basic position, in an initial section of the retraction path, the arm 23 is first rotated about an axis perpendicular to the extension direction, in the exemplary embodiment about the second pivot axis 25. This allows the movement of the carriage to be reduced 6 on the movable part 22b of the damper unit 22 can be achieved.
  • the distance of displacement of the carriage 6 against the pull-out direction 4 is therefore greater than the distance of displacement of the movable part 22b of the damper unit.
  • the onset of the damping effect of the damper unit 22 is therefore less abrupt.
  • This rotation of the arm 23 in the initial section of the retraction path could also be omitted.

  • the rotation of the arm 23 about the axis perpendicular to the pull-out direction 4 (which in the exemplary embodiment is formed by the second pivot axis 25) is caused by the force acting on the arm 23 in the area of its first pivot axis 24 from the retraction spring 13 via the spring lever 14 and the carriage 6 is exercised.
  • the movable part 22b of the damper unit is guided by engagement of the axle journal 26 and a further guide pin 34 of the movable part 22b into the link 30 of the base body 5.
