Definitions

  • the present invention relates to a device for automatic locking of a rolling blind in the lowered position, unlocking it also automatically when the blind is being raised, the device being of very easy construction and operation, ready to be assembled and of very reduced cost.
  • the object of the present invention is to provide adevice whereby both locking and unlocking operations occur automatically in a simple, reliable and economic way with the downward and upward movement of the blind, respectively.
  • the present invention solves this problem in an optimal way by a device consisting of a tab which is urged by a spring and is automatically inserted in a seat made in the blind slide at the end of the blind descent or closure stage, and is automatically withdrawn from said seat at the beginning of the blind ascent or opening stage, being drawn by a cable fixed to the blind winding roller.
  • the rolling blind 1 as it is well known, consists of several slats 2, preferably made of metal, articulated to one another by their complementary edges 3 and 4 inserted into each other.
  • the blind is wound on a roller 5 arranged inside a box 6 and runs in slides or rails 7 placed on both vertical sides of the opening (door or window) to be protected by said blind.
  • the automatic locking device 8 is applied on one of the uppermost slats of the rolling blind and preferably on the third slat starting from top, that is from the first slat fixed to the roller 5.
  • said device 8 consists of a metal box-like housing 9 with mounting lugs 10, in which a metal channel 11 is arranged by suitable means such as spot-welding, said channel being the rail or guide for a compression spring 12 coaxially wound around a control cable 13.
  • a metal channel 11 is arranged by suitable means such as spot-welding, said channel being the rail or guide for a compression spring 12 coaxially wound around a control cable 13.
  • Another shaped metal plate 14 slides inside housing 9 as a guiding and fixing member for a locking tab 15 and has a central tongue 16 to which the control cable 13 is connected.
  • the metal cable 13 is fixed to said tongue 16 by a riveted member 18 and the angular transmission of the cable 13 is obtained by two cylindrical pins 19 provided with sliding races 20.
  • the cable 13 fixed to the locking tab 15 runs inside the compression spring 12, passes through a hole in the housing near the cylindrical pins 19 and sliding on their races 20 extends to the roller 5 for the blind 1, and is anchored on the roller surface by any suitable fastening system.
  • Operation of the device according to the present invention is obtained by unwinding the blind and at the end of the descent, cable 13 becomes slackened so that the spring 12 may push outwardly the locking tab 15, which on finding a suitable seat (not shown) in the guide rail 7, enters it and automatically locks the blind.
  • the cable 13 is stretched and draws the locking tab 15 inside the channel 11 against the force of spring 12 and causes the tab to be withdrawn from the seat in the rail 7 so as to unlock immediately and automatically the blind as soon as its winding is started.
  • the device according to the present invention may be applied on both sides of the rolling blind as the device is ambidexterous without requiring any modification, as already stated.
