Multi-point lock of the roller shutter consisting of the safety guide rail(5) the mounting brackets (1) with the locking mounts (2) on each guide rail, the pins (3) on each base with the bolt (4) for a second shaft, a spring (7) at the end rail of each guide rail, wire (6) for transmission, the starter (10) within the shaft cup, the striker of the starter(8) and finally two rope bases (9α - 9β) for transmission under angle. The roller shutter curtain ends at the end rail of the rolling shutter, the starter is released, the point of the exit of the starter no longer exits, it activates the striker of the starter, it pulls the wire ropes, the ropes rotate the support bases of the pins, the pins make a straight motion and lock the roller starter curtain. The unlocking is made by the springs pulling back the wire ropes when the starter enters the shaft mug. The advantage of this invention is that human intervention is not necessary to lock or unlock the roller shutter.
摘要:
A braking device for slowing the winding velocity of movable curtains with spring winding, such as mosquito screens and the like, which comprises a rotor housing (5) within which a rotor pin (4) is coupled, the space existing between rotor pin (4) and rotor housing (5) being filled by a viscous fluid (6) adapted to generate friction in case of rotation of the rotor pin (4) within the rotor housing (5), for the generation of a torque resisting the rotation of the rotor pin, a gasket seal (3) being provided between the rotor pin and the rotor housing (5).
摘要:
A window covering control assembly is used in a window covering system. The window covering control assembly comprises a driving module and a speed control module, and is provided in the shell, engaged to the weight element for simultaneous operation therewith. The driving module comprises a cord collecting assembly mounted in the shell. The cord collecting assembly is configured to operate in a first direction while a first driving force acting upon the cord collecting assembly such that the weight element descends away from the shell. The first driving force comprises at least a weight of the weight element. The speed control module is positioned corresponding to the driving module. A resistance force is selectively generated between the speed control module and the driving module, and this force reduces an operation speed of the cord collecting assembly in the first direction.
