Definitions

  • the present invention relates to a device for fixing a sliding element to a rail of a drawer slide, with an adapter that can be fixed to the sliding element, a rail of a drawer slide to which the sliding element is fixed via a locking device which has a locking projection which engages in a locking receptacle, wherein the rail and the sliding element are held together by a locking element and a piece of furniture.
  • DE 10 2018 108646 A1 discloses a device for fixing a sliding element to a pull-out runner, in which fixing takes place via a locking connection with a locking projection and a locking receptacle in order to prevent movement of the sliding element in the longitudinal direction of the rail.
  • This device has proven itself because the locking connection can be easily installed and is effectively secured by a holder.
  • it can happen that when an end position of the rail of the pull-out guide is reached, the pushing element is moved slightly relative to the rail, since there is play between the latching receptacle and the latching projection. This leads to a disturbing development of noise.
  • a sliding element is fixed via an adapter on a rail of the pull-out guide with a latching device which has a latching projection which engages in a latching receptacle, with a compensating element being able to be inserted into the same latching receptacle in order to minimize the play of the latching projection in the latching receptacle to reduce.
  • a movement of the pusher element relative to the rail of the pull-out guide can be reduced when the compensating element is inserted into the latching receptacle. This improves the attachment of the pusher on the rail and reduces movement of the pushing element in the longitudinal direction of the rail when it arrives at a stop.
  • the compensating element is preferably pretensioned towards the latching receptacle.
  • the compensating element can thus be tensioned towards the latching receptacle by the force of a spring or another prestressing element, so that the compensating element can be automatically inserted into the latching receptacle.
  • the compensating element can thus still be arranged outside of the locking receptacle and only inserted into the locking receptacle if there is sufficient play on one side of the locking projection between the locking projection and the locking receptacle, which is greater than the thickness of the compensating element.
  • the compensating element can be designed integrally with the locking element.
  • the compensating element can also be provided at the desired position in order to be inserted into the snap-in receptacle if necessary.
  • the locking element is preferably designed as a U-shaped molded part or comprises this, which has a receptacle into which an end section of the rail, the pushing element or a plug inserted in the rail and an edge of the adapter are inserted.
  • the U-shaped molded part thus encompasses the rail or the plug on the one hand and the adapter on the other hand and holds them together in a direction perpendicular to the longitudinal direction.
  • the latching device then fixes the adapter and rail relative to one another directly or via the interposition of a plug in the longitudinal direction of the rail.
  • the locking receptacle can be formed by an opening or receptacle in the rail or a plug engaging in the rail.
  • the opening can be formed in the adapter. It is also possible to provide several latching receptacles, arranged one behind the other in the longitudinal direction, in order to enable a preliminary latching and an end latching.
  • the latching projection is preferably formed on a movable web and the compensating element rests against an end face of the latching projection.
  • the locking projection can, for example, on a movable web, in particular be made of a metal sheet, so that the compensating element is provided on an end face of the metal sheet in the locking projection.
  • the locking projection can be formed integrally with the adapter to reduce the number of components.
  • the locking projection can also be formed integrally with the rail or integrally with the locking element.
  • the latching projection is provided on a separate spring element which is pivotably mounted on the locking element.
  • the locking element can be made of a different material, for example plastic, than the latching projection, which is made of metal, for example.
  • the compensating element is designed as a strip-shaped band spring.
  • the ribbon spring can have a loop-shaped section in order to prestress the compensating element towards the snap-in receptacle.
  • the material of a stop surface of the compensating element preferably has a lower modulus of elasticity than a stop surface of the latching projection. Additionally or alternatively, the material of a stop surface of the compensating element can have a lower hardness than a stop surface of the latching projection.
  • the compensating element In the mounted position, the compensating element is at least temporarily subjected to a compressive force by the latching receptacle, with the compensating element being supported on the latching projection.
  • several snap-in receptacles for receiving the snap-in projection can be provided on the rail and/or on the stopper on the rail or on the pusher element and/or on the adapter.
  • the thickness of the compensating element is preferably in a range between 0.1 mm and 1.5 mm, in particular 0.3 mm and 1 mm. As a result, with a relatively small thickness of the compensating element in the longitudinal direction of the rail, the compensating element can be inserted into the latching receptacle if there is appropriate play there.
