Definitions

  • the invention relates to a self-retracting device for a furniture part which can be pulled out of a furniture body by means of a pull-out guide, comprising a slide which is displaceably mounted by a base body and which, against the force of a pull-in spring, moves from a basic position into a waiting position
  • Extending direction is displaceable, in which it is held by a holding device, wherein to move the carriage from the basic position in the
  • Waiting position of the carriage can be uncoupled from the carriage.
  • Self-retracting devices consists in the fact that the extension of the retracting spring changes over the retracting distance, with the result that at the end of the
  • Basic position is significantly lower than the force acting on the carriage in the waiting position when the driver couples to or disconnects from the carriage.
  • the operator perceives the highest force that he has to operate as relevant for ease of use. This highest force occurs when the carriage is in the waiting position (i.e. shortly before the driver is uncoupled when it is pulled out).
  • the force acting on the slide in its basic position which has the lowest force in such systems, is relevant for the reliable locking of the closed drawer
  • constant force springs also called roller springs
  • Constant force springs require a relatively large amount of space and have a comparatively small amount
  • WO 2013/138826 A1 shows a closing device in which the driver cooperates not with a sliding carriage but with a closing lever which can be pivoted about a pivot axis and which is acted upon by the drawing spring.
  • the self-retracting device is relatively large and the pull-in distance over which the self-retracting device acts is compared to
  • Another closing device in which the driver with a
  • Swiveling pull lever cooperates is apparent from DE 10 201 1 051 907 A1.
  • the pull-in spring does not act directly on the pull lever but on a further pivotably mounted lever, the connection between the pull lever and the further lever being pivotable on the pull lever and on the other lever attached connecting arm. In this way, the force curve can be adjusted.
  • the disadvantage here is again the required installation space and the relatively small draw-in distance.
  • the object of the invention is to provide an advantageous self-retracting device of the type mentioned in the introduction, in which an advantageous force profile of the retracting force acting on the driver can be achieved with a relatively large retracting distance and a relatively small installation space. According to the invention, this is achieved by a self-retracting device with the features of claim 1

  • This slide of the lever or of the base body slides, at least in a section in which the axle pin is located, obliquely to the pull-out direction, thus enclosing an angle unequal to 90 ° with the pull-out direction.
  • This angle is advantageously in the range from 50 ° to 85 °, preferably in the range from 65 ° to 80 °.
  • the backdrop of the lever or the base body can be designed with a curved course. This enables a further adjustment of the spring force acting on the slide.
  • the pull-in spring acts on the lever in the region between the first and the second pivot axis.
  • the lever on which the pull-in spring engages is therefore a one-armed lever. This contributes to the saving of installation space.
  • the coupling of the carriage to the driver is preferably carried out via a tilting part which is arranged on the carriage and can be tilted about a tilt axis.
