Abstract:
Operating circuits (17, 50, 71, 97) for a solenoid-actuated lock (10) mounted interiorly of a garage door (12), to provided additional security. The operating circuits are electrically connected to the solenoid operator (20) of a normally closed latch (22) that cooperates with the garage door in the closed position. The circuits are designed for use with an automatic garage door opener (19) or a manually opened garage door (12), and include integrated circuit logic (50, 97), relay logic (17, 71), or the equivalent to allow authorized opening of the garage door; if a forced attempt is made to open the garage door, when the garage door is in the secured position, the circuitry will activate an alarm (H) or other security device and prevent the garage door from being opened.
Abstract:
The invention pertains to a one- or two-leaf sliding, swinging or pocket door with electrical, pneumatic or hydraulic drive (10, 30), especially for vehicles. To avoid the risk of pinching due to built-in elements in the side closure region, the invention provides a spindle (12) to which the door leaf or leaves (1, 2) is/are connected by a nut (21, 32), with the spindle in the case of two-leaf doors being symmetrical to the center of the door and with the door drive producing either a rotational action in the spindle (12) or a linear action in the door (1). The spindle is fitted on one side with a free-wheel (23) and, preventing rotation of the fixed part of the free-wheel, an engaging and disengaging brake or coupling (24-28), thus avoiding a closing device in the side closure region.

PURPOSE: A brake system for a floodgate winch with integrated hand and foot brakes are provided to reduce the volume of a device, to lower the cost for manufacturing, and to rapidly perform braking and locking functions. CONSTITUTION: A brake system for a floodgate winch with integrated hand and foot brakes comprise a housing, a brake operating unit(30), a hand brake unit, and a foot brake unit. The brake operating unit touches an input shaft for being operated by the hand and foot brake units, and comprises a band drum(31) and a spring(32). The brake operating unit implements a brake by moving one side end and tightening or loosening a built-in wheel.

PURPOSE: A blind textile lowering speed control apparatus is provided to effectively prevent high-speed lowering of a blind textile by controlling a lowering speed to smoothly lower a blind textile by a user when lowering a blind textile. CONSTITUTION: A blind textile lowering speed control apparatus(100) includes a winding unit(140), a locking unit(160), a unlocking unit(200) and a rotary power control unit(230). The winding unit lowers a blind textile(W) when a winding bar(130) and a driven connector(120) rotate in the same direction and heightens the blind textile when the winding bar and the driven connector rotate in the opposite direction. The locking unit stops lowering of the blind textile by temporarily blocking rotation of the driven connector when lowering the blind textile. The unlocking unit unlocks the locked state of a brake spring(180) by the locking unit and lowers the blind textile. The rotary power control unit buffs and transfers a rotary motion of a rotary clutch(250) between a rotary push bar(210) and a rotary clutch(250) to the rotary push bar side.
Abstract:
PURPOSE: A hinge with a speeding prevention function is provided to prevent damage to a door and a door frame when the door is suddenly opened and closed by forcefully controlling the rotation of the door. CONSTITUTION: A hinge with a speeding prevention function comprises a fixed bracket(110), a rotating bracket(120), and a speeding prevention shaft(130). The fixed bracket is fixed to a door frame and has a first pipe(111) and a second pipe(112). The rotating bracket is fixed to a door coupled to the door frame and has a third pipe(121). The speeding prevention shaft comprises a stopper(140) composed of a stopper pin and a weight.
Abstract:
An apparatus for automatically opening and closing a floodgate is provided to minimize damages caused by flood by measuring differences in water levels between inside and outside levee in real time and rotating a motor in forward and reverse direction for opening and closing the floodgate at right timing. An apparatus for automatically opening and closing a floodgate(111) comprises a motor(211), a band brake(220), a reduction gear, a rotary shaft, a chain belt, a sprocket(123), a floodgate guide rail, a plurality of electronic water level meters(216,217), and a control circuit. The motor is configured to raise and lower the floodgate installed to levee. The band brake is configured to hold the rotary shaft of the motor. The reduction gear reduces RPM of the motor while serving as a force intensifier. The rotary shaft moves the floodgate up and down. The chain belt is installed on left and right sides of the floodgate at opposite ends of the rotary shaft. The sprocket is installed in a central portion of the rotary shaft to deliver output of the reduction gear to the chin belt, having the floodgate hung on its one side, and a counterweight(114) hung on the other side. The floodgate guide rail is projected to the outside. The electronic water level meters are installed to each predetermined position. The control circuit controls each component to automatically open and close the floodgate.
