Abstract:
A hinge assembly includes a damping unit mounted on a securing seat that is connected to a door frame, a housing embedded in a door panel, and a hinge member and a positioning member interconnecting the securing seat and the housing. The damping unit includes a fluid cylinder and a piston rod having an actuating end pivoted to the positioning member. Due to the presence of the damping unit, movement of the door panel relative to the door frame can be damped.
Abstract:
A damper mechanism installed on an opening and closing device that has an arcuate plunger with the same radius of curvature of the cylinder it slidably mates with. A torsion coil spring causes the sliding action of the plunger into the cylinder in one direction.
Abstract:
The invention relates to an air damper for mobile furniture parts, such as drawers or doors, consisting of a cylinder that is open at one end and a piston with seal that is movable in the longitudinal direction in this cylinder and that is connected to a ram. According to the invention, there is a small drilled hole provided in the outer wall of the cylinder near the closed end section of the cylinder.
Abstract:
A self-closing sliding door assembly comprising, a doorway (2) in a wall (4), a substantially planar door (6) mounted for slidable movement with respect to the doorway to open and close the doorway, a closer (12) mounted on one of the door (6) and wall (4) having a drive shaft (14) rotatable about an axis, and an arm assembly having first and second arm members (16, 18) connected to each other by a first pivotal join (20), the first arm member being connected to the drive shaft and the second arm member being connected by a second pivotal join (22) to the other of the one of the door and wall, wherein the drive shaft is arranged to urge the first arm member to pivot about the axis whereby the arm assembly urges the door to close the doorway.
Abstract:
A sliding door assembly comprises a frame assembly, a sliding panel carrier, and a sliding panel mounted to the sliding panel carrier. The sliding panel carrier is mounted to the frame assembly for generally rectilinear movement to enable movement of the sliding panel between a closed position and an open position. The sliding panel carrier has a pivot pin receiving opening. A door controlling unit moves the sliding panel carrier in a generally rectilinear manner between the open and closed positions. The sliding panel has a mounting bracket mounted to the top rail thereof. The bracket includes a pivot pin that moves between extended and retracted positions. The sliding panel is mounted to the sliding panel carrier by inserting the pivot pin into the pivot pin receiving opening. As a result, the sliding panel can swing relative to the frame assembly through a breakout movement from a normal, non-breakout position to a breakout position. The bracket, the pivot pin, and the pivot pin receiving opening are constructed and arranged such that, when the sliding panel is moved in a swinging manner to the breakout position thereof, a load applied to the sliding panel that tends to pivot the sliding panel about a point spaced from the pivot pin creates a reaction force that is applied to the pivot pin and is transmitted to the sliding panel top rail through the bracket.
Abstract:
In an item of furniture having a movable furniture part, such as a drawer, door or folding part, there is provided a damping means which damps movement of the movable furniture part in the closing phase of the closing and/or opening movement. The damping means is constructed as a negative-pressure damping means or combined pressurised and negative-pressure damping means. It has a piston (3) with a resiliently deformable piston part (6) in the piston rod (4), this resiliently deformable piston part (6) being pressed against the cylinder wall during the damping procedure.
Abstract:
A door stop for hollow walls having two drywall surfaces. The door stop comprises a cylindrical housing having an outwardly turned flange serving as a trim plate engaging the drywall surface exposed to the door knob of a swinging door. The flange is located at the exposed end of the housing. A piston occupies and is entrapped within a chamber formed in the housing. The piston is exposed to the door knob and presents surface roughly flush with the outer surface of the wall. The piston receives impacts when the door is swung so that the door knob strikes the wall. A spring inside the housing decelerates the piston responsive to the door being swung until contact with the wall ensues, and subsequently returns the piston to its original position. The chamber of the housing communicates to the exterior by a small orifice, so that piston movement is pneumatically dampened. A brace formed at the rear of the housing contacts the other drywall surface of the wall, such that impact forces are distributed over both drywall surfaces of the wall. The brace, which in alternative embodiments is selectively C-shaped or cruciform, is friction fit the rear wall of the housing.
Abstract:
The invention relates to an air-controlled damper which attenuates the motion of movable components. Sealing between the movable components is effected by a separation means which is fixed to the cylinder and the piston in the hollow space of the cylinder.
Abstract:
A damper device includes a casing, a rotor partly housed in the casing, a viscous fluid filled in the casing around the rotor, and a torque generator for generating a torque during a rotating stroke of the rotor. The torque generator includes a fluid torque adjuster for producing a relatively large torque in at least a terminal range of the rotating strokes in normal and reverse directions of the rotor.
Abstract:
In order to provide a container 1 having a door 2, in particular a luggage compartment for aircraft, the door 2 being mounted via at least one hinge or the like on the container 1 such that it can pivot, having an apparatus for assisting the movement of the door 2 into the open position and for holding the door 2 in the open position, and having an apparatus for holding the door 2 in the closed position, in the case of which container the structural components have as small a physical size as possible and thus occupy as little volume in the container 1 as possible. It is provided that the apparatus for assisting the movement of the door 2 and, possibly, an apparatus for damping the movement of the door 2 are arranged essentially around the pivoting axis of the door 2. The components relating to this are ideally integrated in the or each hinge. The damping of the movement of the door 2 advantageously reduces as the opening angle .alpha. of the door 2 increases or as the rate at which the door 2 is opened reduces.
