Definitions

  • the present invention relates to a braking and/or accelerating device for movable furniture parts with a housing that can be fixed to a first furniture part and on which a driver can be moved along a guideway between two end positions, with the driver being connected to a damper which dampens the movement of the driver brakes in one direction, and an activator which can be fixed to a second furniture part and which can be brought into engagement with the driver with a contact section in order to brake a movement of the second furniture part relative to the first furniture part, a piece of furniture and a method for assembling a braking and/or or accelerator device.
  • the DE 10 2013 102 939 A1 discloses a braking and/or acceleration device in which an activator can be brought into engagement with a driver that can be moved along a guide device.
  • the activator is pivotably mounted and can be pivoted over a ramp when a sliding door moves in order to engage with the driver.
  • Such braking and/or acceleration devices or retraction devices are known for movable furniture parts.
  • the activator and the driver are mounted independently on different furniture parts, which then have to be brought into engagement with each other in the installed position. Due to assembly tolerances, there may be insufficient or excessive overlap between the activator and driver, especially in the case of sliding doors that can be moved along a guide rail within a certain tolerance range, which can lead to malfunctions.
  • the braking and/or acceleration device comprises a housing with a movable driver which can be brought into engagement with an activator, a first guide element being provided on the housing and a second guide element being provided on the activator, which are guided linearly relative to one another.
  • the housing of the braking and/or acceleration device can be aligned relative to the activator after assembly by the guide elements, which ensures reliable positioning and sufficient overlapping of the activator and the driver. Even if assembly tolerances cause certain deviations in the distance between driver and activator, for example in the case of a movable sliding door, reliable functioning of the braking and/or acceleration device can be ensured via the guide elements.
  • the linear guide preferably extends parallel to one another between the first and second guide element and the direction of movement of the driver.
  • the first guide element is preferably designed as a web and the second guide element as a channel-shaped receptacle which engage in one another.
  • the web can be formed or fixed on the housing and the channel-shaped receptacle for the web can be formed or fixed on the activator.
  • a receptacle for a web and the web or projection can be formed or fixed on the activator on the housing.
  • the guide elements can optionally be formed integrally with the housing or the activator or be fixed to them via one or more components.
  • the web preferably extends over at least 50% of the length of the travel path of the driver, for example between 70% and 100%. Thereby the web can essentially fulfill a guiding function over the entire length of the range of movement of the driver.
  • the housing is designed in multiple parts and includes a first housing part with a guide track for the driver and a further housing part with a guide element.
  • the housing part with the driver can be used either for a right or a left side of a piece of furniture, with the further housing part being designed as an adapter in order to be able to fix the housing with the driver in different positions on a piece of furniture.
  • the braking and/or acceleration device can be designed as a braking device and can include a damper, which is designed for example as a linear damper and includes a damper housing and a movable piston rod with a piston in the damper housing.
  • dampers are known in particular as fluid dampers and can be connected to the driver.
  • an energy accumulator in particular a spring, can also be provided on the braking device in order to prestress the driver in one of the two end positions. Then the braking device forms a self-closing mechanism. If the force accumulator acts in the opening direction of the movable furniture part, for example in conjunction with a locking mechanism for locking the movable furniture part in an end position, then the braking and/or acceleration device is designed as an acceleration device.
  • the surface(s) of the activator and/or the web can be provided with a friction-reducing coating, at least in certain areas.
  • the braking and/or acceleration device is preferably used in a piece of furniture with a furniture body and at least one sliding door guided on the furniture body in order to be able to brake the sliding door when it moves into an end position.
  • the activator can be fixed on an inside of the sliding door to save space.
  • the housing can be fixed on an underside on a top panel of the furniture body.
  • the housing preferably has a downwardly projecting web which can be inserted into an upwardly open, channel-shaped receptacle on the activator. This allows through the channel-shaped recording and linear guidance and exact positioning of the activator relative to the driver can be effected on the web.
  • the end position of the movable furniture part can be either a closed end position or an open end position of the sliding door.
  • an activator is fixed to a movable furniture part with a second guide element.
  • the movable furniture part is then moved into an end position, with the activator being aligned relative to the driver via the first guide element and the second guide element, in particular in order to set the distance between a contact section of the activator and the driver.
  • the order of the assembly steps can be selected as desired.
  • the housing is preferably placed beforehand on a side wall of a furniture body and on a guide rail on the top panel of the furniture body for alignment, in order then to be fixed to the top panel and/or the side wall using fastening means such as screws.
