The invention is useful in the field of road systems.
Abstract:
A hinge assembly includes a housing, an arm and at least one spring. A damping device includes a damper having a piston rod, a maintaining member secured in the housing and an adjustment member. The adjustment member is movably connected to the maintaining member and has a protruded portion located corresponding to the piston rod of the damper. When the adjustment member is moved to a first position relative to the maintaining member, the protruded portion of the adjustment member is located toward the piston rod of the damper, so that the piston rod contacts the protruded portion and retracts to perform damping function. When the adjustment member is moved to a second position relative to the maintaining member, the protruded portion of the adjustment member is moved away from the piston rod of the damper, and no damping function is available.
Abstract:
The invention relates to a furniture damper for damping a movement of a movably mounted part of a piece of furniture or a movably mounted component of a furniture fitting, comprising a piston arranged in a fluid chamber, a damping action being carried out by a relative movement between the fluid chamber and the piston, in addition to a sealing device for sealing the fluid chamber, said sealing device comprising a first abutment element and a second abutment element that is movably mounted in relation to the first abutment element and designed to seal the fluid chamber. A spring is arranged between the first abutment element and the second abutment element, said spring being compressible by the relative movement of the first abutment element and the second abutment element essentially up to the thickness of the cross-section of the spring.
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:
Door construction includes a door panel and at the top and at the bottom each time a self-closing pivot hinge. Each of the pivot hinges includes a spring which extends along the rotation axle and which provides a self-closing function to the pivot hinge. Each of the pivot hinges includes a first cam element and a second cam element which are pushed onto each other by the spring and push the door panel towards the closed position under the influence of the spring pressure. The first cam element includes at least one protrusion which upon rotation runs along a running surface with inclined parts of the second cam element. The second cam element is movably mounted in longitudinal direction of the pivot axle by means of a pen which is accommodated in a slotted hole of the second cam element. The slotted hole extends at least partly between the inclined parts of the running surface.
Abstract:
A spring power setting indicator for a closing apparatus for a wing such as a door or window, including a closer housing in which a compression spring is disposed. The spring power setting indicator includes a collar defining a threaded opening adapted to engage an adjustment screw for adjusting the bias of the compression spring. The collar may be substantially disc-shaped, and has a peripheral side that defines an annular channel in which a magnetic ball is disposed. An indicator housing with indicia of closer size may be mounted to the closer housing. Another magnetic ball may be disposed in the indicator housing. The magnetic balls are attracted to each other, and the ball in the indicator housing follows the ball in the channel as the collar moves in response to turning of the adjustment screw, permitting external reading of closer size with the indicia based on ball position.
Abstract:
A locking device for securing a motor vehicle component which is displaceable relative to a motor vehicle structure and which may be secured by means of the locking device within a displacement range in a respective position of rest reached by displacement is provided. The locking device comprising at least one first frictional element and at least one second frictional element, which is moved relative to the first frictional element upon displacement of the motor vehicle component and thereby may slide with a friction surface along a friction surface of the first frictional element under sliding friction conditions and which, in a respective position of rest of the motor vehicle component, with its friction surface bears against the friction surface of the second frictional element under static friction conditions. A flowable additional medium is provided which may be brought, upon a relative movement of the frictional elements, between their friction surfaces.
Abstract:
A drive device for moving a flap of a vehicle includes a first fastening element which can be connected to one of a moveable component and a fixed component, and a housing tube which is axially movable relative to the first fastening element. The housing tube has an end opposite the first fastening element which carries a second fastening element which can be connected to the other of the moveable component and the fixed component. A spindle drive includes a threaded spindle having end mounted for rotation in the housing tube and fixed against axial movement with respect to the housing tube, and a spindle nut arranged on the threaded spindle. The spindle nut is connected to the first fastening element and secured against rotation with respect to the housing tube, and a rotary drive is arranged to drive the spindle in rotation.
Abstract:
The hinge for wings or doors, in particular of electrical appliances, comprises a first box-shaped body, a second box-shaped body, a connecting element between the first and second bodies, and a damper cylinder for applying on the second body an action damping its movement towards the first body.
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 rotatable 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).
