Abstract:
A manually assistable electric driving device for a lid of an automobile luggage compartment has a clutch mechanism disposed between an electric motor and an output member drivingly connected to the lid. The clutch mechanism is so constructed that, when the lid is being driven by the motor in either direction, the lid can be manually moved in the same direction and at a speed higher than the speed caused by the motor drive.
Abstract:
A retraction device for automatically closing a panel, such as a door or window, after the panel has been opened. The retraction device includes a drum, a coiled spring power assembly for driving the drum, a centrifugal brake for controlling the power assembly and the drum to eliminate slamming of the panel during closing, and a gear train transmission assembly to connect the power assembly and the centrifugal brake. In one embodiment, the drum is a spool which carries a cable to connect the panel to the retraction device. In another embodiment, the drum has a rim which frictionally engages a frame supporting the panel. The centrifugal brake is adjustable to take into account a wide range of panel sizes and frictional conditions. This adjustment can be made through an aperture in the device's housing for quick and easy on-site installation. A one-way clutch mechanism is coupled between the power assembly and the brake to actuate the brake only when the panel is being retracted. This clutch mechanism is formed by two members, each of which is integrally molded of plastic.
Abstract:
The invention relates to an improved safety device for stopping cable payout in an overspeed condition, and particularly to a safety device for securing an object from falling because of failure of a hoisting device. According to the invention, an inertial actuated drum locking mechanism comprises an inertial member mounted on a cable rewind drum. The inertial member is pivotable so that when actuated by inertial force above a predetermined value due to overspeed rotation of the drum, the inertial member moves to engage a fixed member for arresting further motion of the drum. The inertial member is held in place until the outward force exceeds the predetermined value, at which point, the inertial member toggles outward to provide rapid and positive engagement of the locking mechanism.
Abstract:
A safety mechanism for preventing door slamming includes a board and a pivot extending from the board. A rotatable arm is attached at a first end to the pivot. Door arresting wedge (AW) is attached substantially perpendicularly to the second end of the arm. One or more magnets are disposed on the board for attracting the arm. One or more magnets disposed on an edge of the arm, and a matching stopper is used to limit the rotation of the arm.
Abstract:
Ce dispositif présente un flasque (17) entraîné en rotation par l'arbre présentant plusieurs cavités (19) dont, chacune comporte une paroi, qui servant à l'appui à une masselotte (18) en condition de fonctionnement, est inclinée par rapport à l'axe de rotation du flasque d'un angle inférieur à 90°, chaque cavité présentant une extrémité proximale située à proximité de l'axe de rotation du flasque et une extrémité distale éloignée de l'axe de rotation du flasque, chaque masselotte (18) circulant dans une cavité entre une position de fonctionnement à vitesse normale de l'arbre dans laquelle la masselotte se trouve dans une zone comprenant l'extrémité proximale de la cavité (19) et une position de fonctionnement à vitesse de l'arbre (4) dépassant un seuil prédéterminé dans laquelle la masselotte (18) se trouve dans une zone comprenant l'extrémité distale de la cavité et actionne des moyens de freinage de la rotation de l'arbre.
Abstract:
A mechanism for preventing injury to a person's or child's hand when a door (12) slams against a door frame or jamb. The mechanism comprises a casing (18) positioned within a hollowed-out portion of the door (12). The casing (18) is constructed with an opening (18a) disposed along the edge (12a) of the door (12). A metallic pendulum (20) is housed and suspended within the casing such that the pendulum (20) to swing outwardly through the opening. A raised metal body (14) is attached to the slide molding of the door frame or jamb and engages the outwardly swung pendulum (20) to prevent the door from completely closing.
Abstract:
To avoid complex, larger, expensive automatic closers having ineffective braking of the slamming of the closure, a retraction device (10) including a drum (18), a coiled spring power assembly (22) for driving the drum, a centrifugal brake (24) for controlling the power assembly and the drum to eliminate slamming of the panel during closing, and a gear train transmission assembly (26) to connect the power assembly and the centrifugal brake. In one embodiment, the drum is a spool which carries a cable (20) to connect the panel to the retraction device. In another embodiment, the drum has a rim (131) which frictionally engages a frame (12a) supporting the closure. The centrifugal brake is adjustable to take into account a wide range of closure sizes and frictional conditions.
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:
An opening and closing body control apparatus includes: a first signal receiving unit receiving a first detection signal indicating the presence or absence of contact of a user with an operating portion of an opening and closing body; a second signal receiving unit receiving a second detection signal indicating a movement speed of the body; and a signal output unit outputting a control signal regulating a holding force of the body to a holding force regulating device, wherein the control signal regulating the holding force to a first holding force less than a second holding force is output to the device according to the first detection signal indicating that the contact has been detected, and when the second detection signal indicating that the movement speed body is greater than or equal to a predetermined speed is received when the holding force is the first holding force, the control signal regulating the holding force to the first holding force is output to the device regardless of the first detection signal.
