Abstract:
The invention relates to a damping device for parts of furniture which are joined together by means of hinges and which can be pivoted in relation to each other. The housing contains a damping fluid in the cavity thereof and a resistance element which can be displaced relative to the damping fluid and connected to an actuating element protruding from the housing. During at least one part of the pivoting movement of both pieces of furniture, said actuating element is drivingly connected to the second piece of furniture and transfers the movement distributed to the second piece of furniture to the resistance element. The damping device is arranged in the region of at least one of the hinges which pivotally couples both pieces of furniture, and whereby either the damping housing and/or the actuating element engages with one of the mounting element of the corresponding hinges, at least during the damping process.
Abstract:
A hinge structure is provided. The hinge structure uses a magnetic force and includes a shaft, provided at one side of a cover and rotatably supported by a body. At least one permanent magnet having a magnetic field perpendicular to the longitudinal direction of the shaft is fixed to the shaft. A shaft operation portion is provided in the cover for rotating the shaft by about 180 degrees and rotating between a first position and a second position by a user's operation. At least one electromagnet is arranged at a position corresponding to the permanent magnet of the body, thereby aiding the opening and closing of the cover and absorbing any impact using a magnetic force between the permanent magnet and the electromagnet.
Abstract:
Hardware that improves the safety of operating sectional doors that use torsional coil springs to facilitate door movement. A rotor assembly with centrifugally activated throw-out latches is affixed to the rotating shaft that bears the torsional coil springs. When a spring breaks, the shaft rotates rapidly as cables supporting the door unwind. Rapid rotation causes centrifugal force to bias the latches to an outer position in which they strike a trigger plate, allowing a pawl to move into a position in which the pawl blocks further rotation of the rotor, thus halting the descent of the sectional door. Raising the sectional door manually moves the latches, trigger plate, and pawl to their original position, disengaging the present invention and permitting the door to be lowered slowly without danger of injury.
Abstract:
A damper device applies damping force to a movable body assembled on a fixed body. The damper device includes a damping part, a clutch case attached to one of the fixed body and the movable body in a state having received the damping part, and a rack part moving or relatively moving accompanying movement of the movable body. The damper device effectively operate the movable body.
Abstract:
There is disclosed an engaging/disengaging fail-safe door closing device for a rolling fire door, provided between a power device and a speed reducing device of a door machine, including an electromagnet fixed inside a housing of the door machine and disposed around the outside of a shaft of the power device; a brake device including a shaft sleeve, loosely embracing around the outside of the shaft of the power device and being capable of sliding between the shaft and the electromagnet, on one end of which, there is provided an attracted plate facing the magnet and coming off the magnet by way of the biasing force of an elastic element, while on the other end there is radially formed a brake disk; a driving plate fixed on the shaft of the power device and facing a position where the brake disk is allowed to contact; and a circuit used to control the electromagnet to be electrified to excite in order for actuating the brake when the door reaches a predetermined position, or to release the brake when the power is cut off.
Abstract:
An object of the present invention is to provide an opening and closing member with damper for use in Western style stool or piano and the like which facilitates an easy control of the rotary damper and easy execution of assembling work, and the hinge members corresponding to the opening and closing member side are adjacently disposed at the same side of the two pieces of the hinge members at the side of the proper member. The rotary damper having a directivity is disposed between the hinge members that face each other, and the mounting member at one side of the rotary damper is tied to the mounting member provided at the hinge member of the proper member, and the mounting member of the other side is tied to the mounting member provided at the hinge member of the opening and closing member. With this arrangement, the opening and closing member is swivellably journalled on the proper member with the rotary damper on its axis of rotation, and the damping power of the rotary damper is applied to the swivelling motion as the opening and closing member swivells with the rotary damper on its axis.
Abstract:
A damper unit includes a reel having a spool on which a string is wound and a peripheral rack, and a base rotatably supporting the reel and having a holding portion. A spiral spring has an inner end connected to the holding portion and an outer end connected to the reel for accumulating a biasing force to cause the reel to rotate in a string winding direction in response to rotation of the reel in a string withdrawing direction. A damper device has a rotatable shaft integral with a gear. When the string is pulled out, the spiral spring is resiliently deformed to displace the reel to one side of the base to engage the peripheral rack of the reel with the gear of the damper device.
Abstract:
Hinge with a hinge cup, which can be inserted into a boring in a furniture part, with a damper housing fixed onto the hinge cup, wherein the damper housing can be fastened onto or removably secured to the hinge cup wherein the damper housing is disposed at least partially outside the boring when the hinge cup is inserted into the boring in the furniture part.
Abstract:
A sliding assisting apparatus includes a main body provided on a base or a movable body, and having a pair of sliders disposed in a case; lock members formed on the sliders; coupling parts provided on the case to couple/uncouple with the lock members; a forcing device provided between the two sliders to accumulate a biasing force when one of the sliders is slid to move away from the other; a pair of strikers provided on the base or the movable body; and a switch between a case restrained position and a case restraint released position. One striker is disposed between the first and second sliding positions to cause the movable body to slide toward the first sliding position, and a second striker is disposed closer to the second sliding position than the first striker to cause the movable body to slide toward the second sliding position.
Abstract:
A clutch includes a moving gear member 65 being rotated integrally with a wheel at all times and engaged with a fixed gear member 69 when it is moved in a first direction and disengaged from the fixed gear member when it is moved in a second direction, an armature 61 pushing out the moving gear member 65 in the first direction when it is rotated relatively to the moving gear member 65, and an electromagnetic coil portion 60 that applies brake resistance to the armature 61 by attracting the armature 61 by magnetic force to restrict a concurrently-rotating-state of the armature 61 and the moving gear member 65.
