Abstract: An emergency bi-fold door closing prevention system includes a building having an access opening with an upper edge. A bi-fold door is hingedly mounted to the building wall and includes a plurality of panels each being laterally elongated. The plurality of panels includes a bottom panel having a bottom edge that is positionable adjacent to a floor surface to define a closed position. A safety line assembly is attached to and extends between the building wall adjacent to the upper edge and the bi-fold door adjacent to the bottom edge. The safety line has an extendable length. The length of the safety line assembly extends when the bi-fold door moves toward the closed position below a threshold velocity. The length of the safety line assembly is inhibited from extending when the bi-fold door moves toward the closed position above the threshold velocity.

Abstract: A control device is used to move a pick-up truck tailgate. The control device comprises a first gear arrangement connected to a drive cup and a second gear arrangement that is connected to a motor for driving the second gear arrangement. The control device also includes a clutch arrangement positioned between the first and second gear arrangements. When the clutch arrangement is in an engaged position, it couples the first gear arrangement and the second gear arrangement to transmit torque to the first gear arrangement and the drive cup. When the clutch arrangement is in the disengaged position, the first and second gear arrangements are not coupled. Optionally, the control device comprises a brake unit to slow or stop movement of the tailgate. The control device can be positioned within the pick-up truck tailgate.

Abstract: Hardware that improves the safety of operating sectional doors that use torsional coil springs to facilitate door movement. A rotor assembly with centrifugally activated throw-out latches is affixed to the rotating shaft that bears the torsional coil springs. When a spring breaks, the shaft rotates rapidly as cables supporting the door unwind. Rapid rotation causes centrifugal force to bias the latches to an outer position in which they strike a trigger plate, allowing a pawl to move into a position in which the pawl blocks further rotation of the rotor, thus halting the descent of the sectional door. Raising the sectional door manually moves the latches, trigger plate, and pawl to their original position, disengaging the present invention and permitting the door to be lowered slowly without danger of injury.

Abstract: The invention relates to a device for braking the rotation of a drive shaft of the leaf of a high-speed door. The inventive device consists of a flange (17) which is rotated by a shaft comprising several cavities (19), each of said cavities being equipped with a wall which supports a flyweight (18) in the operating condition and which is inclined in relation to the axis of rotation of the flange by an angle of less than 90°. Moreover, each cavity comprises a proximal end which is located close to the axis of rotation of the flange and a distal end which is located at a distance from said axis of rotation. According to the invention, each flyweight (18) moves in a cavity between a position whereby the shaft operates at normal speed, in which the flyweight is disposed in a zone comprising the proximal end of the cavity (19), and a position whereby the operating speed of the shaft (4) exceeds a pre-determined threshold, in which the flyweight (18) is disposed in a zone comprising the distal end of the cavity and actuates means for braking the rotation of the shaft.

Abstract: When a drive shaft is in a non-drive state, a second drive rotor is in a non-engaged state with a driven rotor with respect to its own rotating direction. When the drive shaft is in a drive state, a rotating force of a first drive rotor is transmitted to the second drive rotor through an urging member. As a result, a power transmitting member revolves, and a centrifugal force arranges the power transmitting member at a second clamping position. The second drive rotor receives a reaction force from a driven rotor via the power transmitting member. As a result, the second drive rotor is relatively rotated in an opposite direction to a rotating direction of the first drive rotor with respect to the first drive rotor, against an urging force of the urging member. As a result, the first drive rotor is engaged with the driven rotor with respect to its own rotating direction. Accordingly, the clutch is stably operated.
