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:
A hinge for furniture comprises a first part to be fastened to a first furniture element and a second part to be fastened to a second furniture element, said first and second hinge parts being rotatably in engagement with each other, a shock absorber being present which comprises a body fastened to the first hinge part and a shock absorbing member movably mounted on said body, the shock absorbing member being adapted to restrain movement of the second hinge part in a closing step of the hinge. Said shock absorbing member and second hinge part having portions magnetically attracting each other to carry out dragging along of the shock absorbing member relative to the body during a reopening step of the hinge, bringing said member back to position for subsequent cushioning of the closing movement of the hinge.

Abstract:
Disclosed is a device (10) for damping or decelerating the movement of parts of pieces of furniture which are movable relative to a stationary part thereof. Said device comprises a cylinder (12) inside which a piston (10) is mounted so as to be movable in a longitudinal direction and which forms working chambers (20, 22) filled with a liquid damping medium on the opposite faces thereof within the cylinder, the dimensions of said working chambers being modifiable according to the position of displacement of the cylinder. The liquid damping medium can be transferred in a throttled manner between the working chambers via overflow port (34, 38) or ducts (42) which are disposed in the piston (14) and/or in the cylinder (12). A piston rod (24) which is sealingly guided out of the associated end of the cylinder is connected to one side of the piston. The movement of the part of the piece of furniture which is to be damped or decelerated is transmitted to the piston via the outer end of the piston rod (24) facing away from the piston. A volume compensating mechanism is provided for compensating the total volume of the working chambers (20, 22), which changes as a result of the volume displaced by the piston rod when the same is inserted into the cylinder. The piston rod (24) is coupled to the piston that is provided with overflow ports (34) so as to be movable by a given longitudinal path while encompassing a non-return disk (36) in the end region facing the piston. Said non-return disk (36) is provided with at least one overflow port (38), has a reduced outer diameter, and is moved into sealing contact with the facing piston face during a damping or decelerating working stroke while being displaced into a position that is spaced apart from said face of the piston during a return stroke. A spring (39) which biases the facing faces of the non-return disk (36) and the piston (14) into the spaced-apart position is arranged between the non-return disk (36) and the piston (14).
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 hinge device includes a frame bracket adapted to be secured to a door frame, a door bracket adapted to be secured to a door panel, first and second links pivoted to the frame bracket and the door bracket, an urging member for urging the door panel to move from an opened position toward a closed position relative to the door frame, and a damping member adapted to be secured to the door frame and connected movably to the second link through a transmission link so as to damp pivoting movement of the door panel relative to the door frame.
Abstract:
A sliding door apparatus for opening and closing an opening in a wall, including a longitudinally extending track member mountable along an upper edge of the opening; a door movably mountable on the track member for side to side movement thereon between an opened and closed position; and damping means disposed within the track member actuatable in response to the side to side movement of the door to break the door's movement as it approaches its fully opened and closed positions.
Abstract:
It is an object of the present invention to provide a rotary damper capable of automatically adjusting an exhibited braking force in correspondence with variation in load.A fluid chamber 2 into which viscous fluid is charged is formed in a casing 1. A vane 3 is disposed in the fluid chamber 2. The vane 3 is formed with a fluid passage 5, and is provided with a valve 6. The valve 6 automatically varies a flow rate of the viscous fluid passing through the fluid passage 5 in correspondence with variation in load. With this structure, it is possible to automatically adjust the exhibited braking force in correspondence with variation in load caused by variation in rotational motion of a subject to be controlled, and to reduce variation in rotation speed of the subject to be controlled to an extremely small value.
Abstract:
An air damper includes a cylinder having a bottom, a piston received inside the cylinder to move freely back and forth coaxially, and an orifice provided in the piston. The piston is formed of a synthetic resin, and has a piston rod extending toward a side of the cylinder opposite to the bottom, and a recess portion provided on a portion facing the bottom in order to prevent sink or the like during molding of the piston. A protruding portion is provided on the bottom of the cylinder to protrude into the recess portion when the piston is fully moved into the cylinder.
Abstract:
A damper has a cylinder and a piston, the piston having two or more parts. A first piston part consists of a rubber-elastic material forced against the cylinder wall during a damping stroke. A second piston part consists of a material that is stiffer in comparison to the rubber-elastic material. The second piston part as seen in the radial direction lies between an area of the first piston part and the cylinder wall. The first piston part may have at least two sections of different hardnesses over its lengths. The piston could also include a piston part that is radially forced outwards to rub against the cylinder wall during damping, the piston part being made as a solid body of a material with rubber-elastic properties which becomes flattened under pressure, deforming in such a way that a friction seal is created between the piston part and the cylinder wall.
