Definitions

  • the invention relates to a locking device for a sliding door system.
  • the invention also relates to a sliding door system with such a locking device.
  • Sliding door systems typically have a door drive with a traction device, for example a belt, and a sliding door drive with a movable carriage for a sliding door element.
  • a locking device is provided which is often arranged on a pulley for the traction means.
  • Such a deflection roller is typically arranged on one side of the door drive that is opposite a traction drive that drives the traction.
  • the deflection roller is blocked by a locking element, for example by a toothed locking disc.
  • Such locking devices typically require a relatively large amount of space.
  • the object of the invention is to enable the locking of a sliding door system with a locking device which requires less installation space.
  • a locking device for a sliding door system comprising a housing, wherein a locking drive, in particular a linear motor, with a stator and a rotor that can be moved translationally with respect to the stator is arranged in a first housing interior first housing interior separate, A locking mechanism with a locking means is arranged in the second housing interior, which can be moved back and forth between a release position and a locking position, and the locking mechanism is coupled to the locking drive via at least one control element connected to the runner and passed through a guide opening in the housing wall.
  • a locking drive in particular a linear motor
  • the locking drive and the locking mechanism are arranged in a common housing in separate housing interiors.
  • the two housing interiors are separated by a housing wall with a guide opening through which a control element connected to the runner of the locking drive is guided, so that a mechanical coupling of the locking drive with the locking mechanism, in particular with the movable locking means, is effected.
  • a compact locking device can be provided with a locking means that can be moved between a release position and a locking position.
  • a first guide roller bearing is arranged on the control element, which is received in the guide opening, in particular such that a bearing ring of the first guide roller bearing that is rotatable relative to the control element can roll on an inner contour of the guide opening.
  • the friction that occurs when the control element connected to the rotor is moved can be reduced by the first guide roller bearing.
  • about the first guide roller bearing and the inner wall of the guide opening can be introduced into the housing forces introduced into the locking means. Such forces can occur, for example, when an attempt is made to move a sliding door element manually while the locking means is in its locking position.
  • a second guide roller bearing is preferably arranged on the control element, which is received in a guide slot of the locking means, in particular such that a bearing ring of the second guide roller bearing that is rotatable relative to the control element can roll on an inner contour of the guide slot. The friction that occurs when the locking means is moved can be reduced by the second guide roller bearing.
  • the locking means has two, in particular identical, guide slots and the runner comprises two control elements, each guided in one of the guide slots.
  • the at least one guide link has a non-linear profile.
  • a movement of the drive element by a predetermined distance is then not converted uniformly into a movement of the locking means by the same distance.
  • the non-linear course of the is preferred Guide links are selected such that, starting from the release position of the locking means, initially a relatively small movement of the drive element is converted into a relatively large movement of the locking means.
  • This relatively steep course of the guide link can merge into a flatter course in the direction of the locking position, so that a movement of the drive element in this area results in a smaller movement of the locking means.
  • the actual locking can take place with greater force.
  • the locking means for moving between the release position and the locking position is mounted so as to be linearly movable, in particular perpendicular to a direction of movement of the rotor.
  • a linear movability of the locking means can reduce the risk of undesired jamming of the locking means with a counterpart, for example a traction means of a sliding door system.

  • Another object of the invention is a sliding door system comprising a door drive with a traction means, in particular a belt, a rope or a chain, a sliding door drive with a movable carriage for a sliding door element, which is coupled to the traction means and which, starting from a closed position, over a distance in at least one predetermined open position is movable, and a locking device described above for locking the door drive.

  • the locking device has a stop for the traction means, the traction means being in contact with the stop when the locking means is in its locking position. It is thus possible for the traction means to be clamped in the locking position of the locking means between the locking means and the stop.
  • the stop is preferably designed as part of a housing of the locking device, so that a particularly compact design can be made possible.
  • the locking means has a carrier element, with respect to which the locking section is movably mounted, the locking section being acted upon by a restoring force, in particular by a spring element.
