Definitions

  • the invention relates to a constant force device for sliding doors and a sliding door system with such a constant force device.
  • Sliding door systems usually have several sliding doors that are attached to drives that are slidably mounted on a rail.
  • Such a sliding door system is disclosed in [1], for example, US6418588B1 .
  • US2004004405A1 discloses a constant force device with a stationary and a movable part, one of which comprises a magnetically conductive area or a permanent magnetic area and the other a permanent magnetic area, the magnetization of which is designed so that at least a portion of the magnetic flux generated is perpendicular to the axial direction of movement of the movably arranged part exits the permanent magnetic area, enters the magnetically conductive area, is guided there and exits the magnetically conductive area again and runs back to the permanent magnetic area.
  • US9752367B2 discloses a constant force device for sliding doors comprising a hollow plastic body coupled to a sliding door, in which a metal sleeve is axially aligned with a fixedly mounted metal rod which penetrates the metal sleeve as soon as the sliding door is moved into the end position.
  • the metal sleeve and the metal rod consist of correspondingly arranged ferromagnetic and / or permanent magnetic materials. As soon as they come into contact with one another, the metal sleeve and the metal rod form a constant force device which pulls the sliding door into the end stop.
  • a sliding intermediate layer is provided between the metal sleeve and the metal rod, which separates the metal bodies from one another.
  • the intermediate layer is arranged on the inside of the metal sleeve.
  • a damping device which comprises a coupling body mounted displaceably within the metal sleeve, which connects to a spiral spring and which can be displaced by the metal rod against this spiral spring.
  • the present invention is therefore based on the object of creating an improved constant force device and a sliding door system with such a constant force device.
  • an improved constant force device is to be created which is suitable as a retraction device for sliding doors.
  • the constant force device according to the invention should always work with reduced losses regardless of external influences and mechanical effects.
  • the constant force device according to the invention should be able to be integrated in a simple manner in new or existing sliding door systems.
  • the sliding doors should be possible to move sliding doors into an end stop with constant force and practically without losses.
  • the sliding doors should be able to be moved as far as possible to the end of the rail so that room openings can be used optimally.
  • the constant force device used should work maintenance-free over a longer period of time.
  • the front end piece of the metal rod directed towards the metal body is provided with a guide device which has at least one bearing element which partially projects beyond the outer diameter of the metal rod and which prevents the metal rod from making contact with the metal body within the receiving channel.
  • the friction that may be generated by the guide device is minimal and limited to punctual contact or to contact in the area of a few mm 2 .

  • the contact zone is advantageously reduced by segmenting the contact zone into a number of preferably three to four contact segments or bearing elements.
  • Misalignments of the metal rod are automatically corrected using the guide device. Vibrations of the sliding door, e.g. impacts or bumps are automatically compensated by means of the guide device.
  • the metal rod Due to the reduction of the otherwise typically occurring frictional forces to a negligible fraction, the metal rod is pulled more powerfully and always with the same force into the receiving channel of the metal body.
  • the air gap is kept free as far as necessary, which is why contamination is avoided and maintenance work is largely unnecessary. Due to the lack of an intermediate layer, such a layer cannot be damaged, worn or deformed, which is why the constant force device according to the invention does not show any signs of wear and tear and no undesirable changes in the properties of the constant force device even with longer operating times.
  • the guide device has a guide body which can be connected to the metal rod and which is made of plastic or metal.
  • the guide device is designed as a guide cap which has a front piece and a mounting ring and which is placed on the front end piece of the metal rod.

  • the guide body can also be connected to the metal rod by a press fit or by glue.
  • the guide body preferably has a mounting opening into which the metal rod, a tapered part of the metal rod or a connector, e.g. a threaded rod can be inserted which can be screwed into a threaded bore in the front end piece of the threaded rod.

  • FIG. 9 shows the constant force device 9 of FIG Fig. 1 with a trailer 400, which is coupled to the carriage 1 and in which a damping device 4 is provided, which can be actuated by means of a transfer rod 42 fixedly mounted in the rail 5.
  • Figure 6b shows the trailer 400 of Figure 6a Sectioned in the longitudinal direction with a view of the damping device 4, as already shown in FIG Fig. 2a is shown.
  • the damping device 4 includes the damping cylinder 41 which has been pushed back completely and which is automatically extended again by spring force.
  • Figure 6c shows in a further preferred embodiment a guide device 6 which is integrated at the front in a receiving opening 20 of the metal rod 2 and which is also shown separately.
  • the front side of the metal rod 2 has a slot-shaped receiving opening 20 which is open to the front and in which a horizontally aligned guide wheel 65 is held, which projects beyond the metal rod 2 on both sides and preferably also on the front side.
  • the metal rod 2 is guided in the receiving channel 30 on the front on both sides. If the guide wheel 65 also projects beyond the metal rod 2 at the front, it is also ensured that the metal rod 2 cannot come into contact with the metal body 3.
  • the guide wheel 65 is held by a bearing shaft 63 which has been inserted from above through a bearing opening 200 into the receiving opening 20.
  • the receiving opening 20 can also be closed at the front and provided, for example, with a buffer.
  • the guide wheel 65 is pushed laterally into the receiving opening 20 and fixed from above by the bearing shaft 63.
  • further guide wheels can be integrated into the metal rod 2.
  • a further slot-shaped receiving opening 20 is provided, which is vertically aligned and into which a guide wheel 65 is pushed from above or from below and fixed by a bearing shaft 63 which is pushed laterally through a bearing opening 200 into the receiving opening 20.
  • a cross-wise arrangement of guide wheels 65 is achieved, which keep the metal rod 2 axially aligned within the receiving channel 30.
