Abstract:
A spring buffer (1) for a furniture item, said furniture item comprising a furniture body (3) and a furniture part (4) being movable from a closed position in or on said furniture body (3), said spring buffer (1) can be arranged relative to said furniture body (3) and said furniture part (4) such that said movable furniture part (4) in its closed end position can be moved against the force of said spring buffer (1) towards the direction of said furniture body (3), said spring buffer (1) comprises a buffer element (6) for said movable furniture part (4), said buffer element (6) being acted upon by a spring (7), wherein said buffer element (6) is movably arranged such that the distance covered by said buffer element (6) against the force of said spring (7) can be changeably adjusted.
Abstract:
An end-stop damper including a damper body in the form of a cylinder, wherein a piston is guided so that it is displaceable in the cylinder receiving chamber. An air pressure is formed in the receiving chamber produces a braking force acting on the piston during its displacement. The receiving chamber includes at least one pressure reducing opening and the piston includes a bellows section which is actively connected to the cylinder according to pressure conditions in the receiving chamber. This invention substantially simplifies the structural design of the end-stop damper because the piston and the bellows section are connected to each other so that they are formed in one piece.
Abstract:
The invention is a fluidic damper which comprises a closed cylinder (100) containing a valve mechanism. The valve mechanism is attached to a piston rod (110), a portion of which (the piston rod) emerges through an opening in one end wall of the cylinder (100). The valve mechanism (90) comprises a disc (10) with an axle (15), a rotable annular cover piece (20) and an annular turning piece (40). A spring (30) is disposed between the cover piece (20) and the turning piece (40).
Abstract:
A noise control device for a steel door includes a buffer, a shock-absorbing member, a stopping member, or only includes a colliding member. The noise control device is installed at any location of a steel door and a casting where noise may be generated when the steel door is closed or opened. The buffer consists of a cylinder, a lower sponge, a coil spring, a rod, and an upper sponge and possibly a colliding member. The buffer can be mainly installed on a deadbolt groove of the casing. The shock-absorbing member may be fixed on the steel door or the casing for reducing sound. The stopping member is fixed on the steel door to face the outer end of the buffer. The noise control device can reduce noise generated in opening and closing as much as possible and preventing the both from disfiguring or denting.
Abstract:
A device designed to control opening and closing of a trunk hood comprises a jack whereof the cylinder is pivotably linked to the vehicle body and the free end of the piston rod sliding in the cylinder is linked to the hood in articulation. The device further has a control member arranged between the hood and the free end of the piston rod and designed to detect a force in the direction closing the hood and to control actuation of the jack in the direction for closing the hood.
Abstract:
A safety structure for a cover device includes a base assembly and a cover assembly. The base assembly has a concave portion. The cover assembly is hinged to the base assembly and may cover the base assembly. The cover assembly has a cover body and a projection, which may elastically protrude out of and retract into the cover body, and may be fit into the concave portion for positioning. The projection is configured such that it may retract into the cover body to prevent an object from being hurt when the cover assembly is placed down and touches the object.
Abstract:
The invention is directed to a simply designed and easy-to-operate brake retardation apparatus in which a push rod is moveable in guides of a housing and possesses a section formed as a gear rack which meshes with a pinion of a shock absorber also retained in the housing.
Abstract:
The electro-mechanical drive includes an electric motor, a transmission and a restoring spring. To improve the capacity to close the door, particularly in the event of a power failure, a large coil spring used as the restoring spring surrounds the electric motor and transmission. The electric motor is short circuited when not powered in order to create a generator effect with consequent damping during movement of the door.
Abstract:
A track has walls which enclose a hollow interior and among these walls are two laterally directed flanges which are separated by a slot that opens downwardly out of the track for the full length of the track. The track contains trolleys having wheels which roll along flanges of the track and the trolleys carry hangers which depend through the slot in the track and are attached to a door or some other suspended device. One of the trolleys also carries a latching mechanism which engages a keeper located within the track to secure the trolleys and suspended device in a predetermined position along the track. The latching mechanism includes a latch bar which pivots on the trolley between engage and release position and a spring which urges the bar to its engage position--the position in which it will engage the keeper upon encountering the keeper. The latching mechanism also includes a release cord which depends from its latch bar through the slot in the track and, when pulled, causes the latch bar to pivot against the bias of the spring.
Abstract:
A drive mechanism comprises a support upon which a drive member is mounted for movement relative to a frame. The drive member comprises first and second elements which are relatively movable, the one of which may be mounted on the other. The elements are interconnected by a resilient member which transmits the drive therethrough, a drive input being coupled to a one element, a drive output to the other element. A detector generates a signal output responsive to relative movement of the elements which may serve to control a drive transmitted through the mechanism. In a preferred embodiment, the support is a rotatable screwed shaft and the first element a traveller thereon upon which the second element is slidably mounted, the elements being interconnected by helical springs.
