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 movement damping device travels along a fixed track on roller wheels. Trolleys mounted on the roller wheels support the door along the track for movement of the door. Eddy-current interaction occurs between travelling magnets mounted on the device and fixed side plates of the track. The trolley moves horizontally as the roller wheels travel along horizontal support rails of the track. The track would be fixed to a supporting host structure and opposing side plates of the track support the respective rails. The trolley travels between the side plates when the door moves. The relative motion between the magnets and the side plates causes eddy-currents in the conducting side plates and consequent motion resistance

Abstract: A fluid damping apparatus includes a housing enclosing a chamber retaining a damping fluid, a piston disposed in the housing chamber and movable between a first end position and a second end position, and a variable volume element disposed in the housing chamber having a first size occupying a first volume in the housing chamber. Increased fluid pressure of the damping fluid (e.g., resulting from increased temperature of the fluid damping apparatus and associated expansion of the damping fluid) compresses the variable volume element to a second size occupying a second volume in the housing chamber smaller than the first volume, to permit expansion of the damping fluid, thereby limiting fluid pressure of the damping fluid.

Abstract: A friction based counterbalance mechanism for coupling with a closure panel of a vehicle to assist in opening and closing of the closure panel, the counterbalance mechanism including: a first housing having a first pivot connection mount for connecting to one of a body of the vehicle and the closure panel; an extension member coupled to the first housing at one end and being extendable and retractable with respect to a second housing coupled adjacent to the first housing along an axis, the second housing for connecting by a second pivot connection mount to the other of the body and the closure panel; a sliding friction mechanism having: a shaped sleeve mounted on an exterior surface of the extension member, the shaped sleeve providing an exterior friction surface; and a resilient friction element mounted to the second housing in a fixed location on the axis, the resilient friction element positioned between second housing and the shaped sleeve and biased into contact with the exterior friction surface; wherein relative movement between the shaped sleeve and the resilient friction element as the extension member is displaced generates sliding friction between the resilient friction element and the shaped sleeve.

Abstract: The present invention addresses the problem of providing a one-way clutch and a one-way clutch-equipped rotating damper device with which it is possible to achieve size reduction. A pawl portion of a slide member comprises a withdrawal surface and an engaging surface. When a gear member rotates toward one side, as inner teeth and the withdrawal surface abut each other, the slide member slides in a sliding direction and the pawl portion is withdrawn from the inner teeth, whereby the gear member rotates independently of a rotor shaft. When the gear member rotates toward the other side as the inner teeth and the engaging surface abut each other, the inner teeth and the engaging surface become engaged, whereby the gear member and the rotor shaft rotate integrally.

Abstract: A storage unit (100) has a storage box (110) and a base frame (130) which is removably mounted to the storage box. A hinge (160) is provided to a hinge mounting section (140) of the base frame (130) and supports a lid (150) so that the lid can be opened and closed. The hinge (160) is composed of two inner arms (170) and outer arms (180). A rotation shaft of the hinge is guarded by the inner arms (170) and outer arms (180), so that objects and fingers are prevented from being caught.
