Definitions

  • the present invention relates to a limit switch device for a drive device for blinds or the like, with a switching device which has electrical limit switches for switching off an electric drive motor in an end position of the blind, and with means for actuating the switching device which can be driven via two mutually concentric, mutually movable switching disks are.
  • a limit switch device of the type mentioned at the outset has become known, for example, from DE 27 39 151 C2.
  • Blinds have sheets of material made of metal, plastic or wood, which are held vertically one above the other by pulling cables, belts or cords.
  • the material sheets can be determined in different positions and aligned with one another in different positions.
  • a drive device In order to be able to move the material sheets of the blind, a drive device has an electric drive motor.
  • a limit switch device is provided within the drive device, which enables the drive motor to be specifically switched off.
  • the material sheets can be brought into the desired position by operating and switching off the drive motor.
  • the limit switch device serves to bring the material sheets of the blind into fixed predetermined positions.
  • the first position can relate to an inclined position of the material sheets, while the material sheets can be placed vertically in the second position. Due to the two positions of the material sheets, different lighting conditions can be created in a room.
  • the electrical limit switches of the known limit switch device can be activated via actuating means which can be controlled via switching disks. Separate actuators are required for each limit switch.
  • the actuating means do not work together, so therefore none Coordination of the actuating means is formed with each other.
  • the limit switches cannot be arranged in a space-saving manner in the area of the actuating means.
  • the present invention is therefore based on the object of further optimizing the interaction of switching disks, actuating means and limit switches.
  • the drive motor can preferably be switched off in a first position, which corresponds to a partial darkening. If the drive motor is still operated, the blind is positioned in a second position, which corresponds to a complete darkening by the material sheets.
  • the actuating disks primarily control the first actuating means. Only when the first actuating means respond and actuate their limit switch can the second actuating means be deflected by the switching disks. The second limit switch can only be operated if the first limit switch is already activated. This ensures that the first limit switch position of the drive motor cannot be skipped or ignored. By driving the switching disks in the opposite direction, the positions of the actuating means are canceled again, so that the limit switch device is again in the idle state or in the assembled state. When the blind moves again, the same end positions are always approached one after the other.
  • the means for actuating the switching device comprise a first and a second pivotally mounted shift lever, which can be supported on the upper sides of the shift disks via shift lever shoulders.
  • the shift discs have guide aids for the shift lever shoulders on their upper sides in order to deflect the shift levers for activating the limit switches, whereby, due to a rotary movement of the outer shift disc, the shift lever paragraphs of the first shift lever first engage with the guide aids of the inner shift disc, the first shift lever subsequently as a result of a rotary movement the second switching disc can activate its limit switch and at the same time can pivot the second switching lever in such a way that switching lever shoulders of the second switching lever also come into engagement with the guide aids of the second, inner switching disc.
  • the shift levers are located in the middle of the two shift discs and can influence each other.
  • the shift levers can rotate in the space delimited by the inner switching disk in order to activate the electrical limit switches, which are located in one plane above the shift levers.
  • the actuating mechanism of the limit switch device therefore requires only a small amount of space.
  • the first shift lever has a lever arm, which at one end merges into an upstanding actuating arm for the limit switch and at the other end continues in an angled connecting arm which, when the first shift lever is deflected, rests with its free end on the second shift lever, the Shift lever is pivotally mounted in the transition area between lever arm and connecting arm, the connecting arm is connected in the center to a T-shaped guide arm, and the guide arm has the shift lever shoulders.
  • the second shift lever with shift lever shoulders at one end can be designed as a contact surface for a counter surface of the first shift lever at its other end and an actuating arm rising up between its ends.
  • Such a construction and arrangement of the shift lever has the advantage that the switching disks, the actuating means and the limit switches can be accommodated in a space-saving manner.
  • these components can be arranged one above the other or one behind the other in a sandwich construction.
  • the shift levers rest on the shift discs and are covered by the limit switches arranged above the shift levers.
  • the revolving inner shift disk can be used to achieve a chronological sequence of the actuation of the shift levers when the first shift lever has come into engagement with the guide aids of the inner shift disk through the outer shift disk.
  • the material sheets of the blind can therefore be fixed in two positions. Therefore, the shift lever shoulders of the first and second shift levers which can be brought into engagement with the guide aids of the inner shift disk are preferably arranged on the shift disks offset from one another by 180 °.
