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 e.g. disclosed in [1], US6418588B1.
  • US2016090770A1 discloses a constant force device for sliding doors which comprises a hollow body made of plastic which is coupled to a sliding door and in which a metal sleeve is axially aligned with a fixedly mounted metal rod which is inserted into the metal sleeve penetrates as soon as the sliding door is moved to 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 constant force device for a sliding door with a first magnetic return or holding means comprising a cylindrical sleeve made of a ferromagnetic material and arranged in a housing, and with a second magnetic return or holding means, which comprises a core made of a magnetic material which protrudes in such a way that it can be received by the sleeve in the region of the end position of the sliding door or is drawn into the sleeve by magnetic force.
  • 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 core is preferably enclosed in a cylindrical sleeve made of plastic material, which forms an intermediate layer between the core and the sleeve.
  • Magnetic materials such as soft magnetic and hard magnetic materials are used for the constant force device.
  • Soft magnetic ferrites have a low, hard magnetic ferrites a high coercive field strength. Magnets are often brittle and inelastic and can easily be destroyed by mechanical influences.
  • the material neodymium-iron-boron e.g. is strongly magnetic, but also very brittle because it is sintered from metal powders.
  • 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, and develop high forces by means of which a sliding door can be pulled powerfully against a stop.
  • 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 able to be moved as far as possible to the end of the rail so that room openings can be used optimally.
  • a guide device is placed, which is designed as a cap and which has at least one bearing element that the Outer diameter of the metal rod at least partially protrudes and that prevents contacting of the metal body by the metal rod within the receiving channel, and that the guide device comprises a front piece and a mounting ring, on the outside of which the bearing element is provided.
  • the friction that may be generated by the guide device is minimal and limited to punctual contact or contact in the area of a few mm 2 or less.
  • a circumference of the contact zone around the metal rod of, for example, 20 mm and a length of the contact zone of, for example, 5 mm, a total contact zone of 100 mm 2 results.
  • the contact zone lies in an area ⁇ 100mm 2 , more preferably in an area ⁇ 25mm 2 and less.
  • a further reduction in the contact zone is advantageously achieved by segmenting the contact zone into a number of preferably three to four contact segments or bearing elements.
  • contact zones in a range of ⁇ 5mm 2 -25mm 2 and less can be realized.
  • 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. At the same time, mechanical effects and damage to magnetic elements are already avoided by these measures. There is no need for a slidable intermediate layer between the metal rod and the metal body. This reduces the possible contact zone and thus also the friction several times over. In addition, the air gap can be reduced to a minimum without interfering contacts occurring.
  • 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 slidable plastic such as polyethylene, Teflon, POM or metal.
