Abstract:
Damping device (30) for hinges (10) for the pivotable articulation of door leaves (12) or door flaps on the carcass of pieces of furniture, in which the hinge has respectively a supporting wall mounting part (18) which can be fixed on the supporting wall (14) and a door leaf mounting part (24) which is pivotably coupled via a linkage mechanism (20; 22) to the supporting wall mounting part and can be fixed on the inner face of the door leaf or flap, and which is preferably constructed as a cup part which is countersunk and engages in a recess in the door leaf or flap and has a laterally projecting fixing flange which bears on the inner face of the door leaf. The damping device (30) has a damper housing which is provided on the door leaf mounting part (24) and which is provided in the cavity thereof with a fluid or gaseous damping medium and a resistance element which is movable relative to the damping medium and is coupled to an actuating element (39) which extends out of the housing. At least during part of the pivoting movement of the mounting parts (18, 24) relative to one another the actuating element is in engaged connection directly or indirectly with the supporting wall mounting part (18) and transmits to the resistance element the relative movement of the mounting parts as they pivot. The damper housing (32) is a separate component which is provided with laterally projecting fixing flanges (38, 46) which can be fixed on the fixing flanges of the door leaf mounting part (24).
Abstract:
The invention relates to a damping device for movable furniture parts, for example for doors or drawers, comprising a piston or plunger which is slidably guided in a hollow body, e.g. a cylinder, with said piston or plunger being impinged upon by spring force into its pushed-out position. According to the invention, the hollow body comprises at least one section of a spiral-shaped stay of the internal screw thread, and/or the piston or plunger comprises at least one section of a spiral-shaped stay of the external screw thread. The stays of the screw threads are glidingly supported one on top of the other, or cams or journals of the hollow body or of the piston or plunger are supported on a screw-thread section of the other component. The pitch of the stays of the screw threads is greater than the pitch at which self-locking occurs.
Abstract:
A rotary damper is provided which can include a valve (6) which automatically varies a flow rate of a viscous fluid passing through fluid passages (5a, 5b) in correspondence with variation in load. The valve (6) comprises a leaf spring. The flow rate-adjusting portion (6g) constituting the valve (6) is provided so as not to close the fluid passages (5a, 5b) when no load is applied and bends so that its one surface side projects when no load is applied and becomes deformed in a direction in which the fluid passage (5b) is closed when receiving pressure of the viscous fluid on its one surface side. The flow rate of the viscous fluid passing through the fluid passage (5b) is adjusted depending on a degree of deformation of the flow rate-adjusting portion (6g) corresponding to magnitude of pressure of the viscous fluid applied to one surface side of the flow rate-adjusting portion (6g). The flow rate-adjusting portion (6g), when receiving pressure of the viscous fluid on its other surface side, keeps the fluid passages (5a, 5b) open at all times.
Abstract:
A control assembly for use with a door closer on a swinging door. The control assembly has a housing adjacent to the door closer, a clip having an actuating and a locking tab, and a biasing member that yieldably biases the clip to a released position. The actuating tab can be actuated from outside of the housing to engage the locking tab with part of the door closer to maintain the position of the door. The locking tab can automatically be released from the door closer by further opening the door whereupon the biasing member returns the clip to its released position so that the door may close.
Abstract:
A door closer includes a body having an external surface and defining an interior space. The body is formed with a passage extending from the external surface of the door closer body and communicating with the interior space. A valve member is located in the passage between the interior space and the external surface of the door closer body. The valve member has a gasket groove and a gasket is fitted in the gasket groove. The gasket groove is configured to allow the gasket to protrude from the groove and/or break when the pressure in the interior space exceeds the pressure at the external surface by a predetermined amount and thereby allow door closer fluid in the interior space to escape from the door closer.
Abstract:
A storage unit is disclosed. The storage unit includes a pair of opposed side walls that are substantially parallel to each other, a rear wall that connects the side walls at rear portions thereof, and a top wall that connects the side walls at top portions thereof. The top wall and the side walls define an opening for receiving objects to be stored within the storage unit. The storage unit also includes a cross member that is connected to each side wall, disposed below the top wall, and cooperates with the top wall to define a door receiving space within the storage unit, and a door constructed and arranged to cover the opening when the door is in a closed position, and to be received by the door receiving space when the door is in an open position.
Abstract:
A refrigerator with a home bar door is smoothly and automatically opened and includes an automatic opening unit, a hook unit, a latch unit, and a damping unit. The automatic opening unit pushes the home bar door to a predetermined angle, so that the home bar door is automatically opened by gravity. The hook unit cooperates with the latch unit to lock or unlock the home bar door. The damping unit includes a casing and is connected to at least one hinge shaft. The automatic opening unit is provided with a push rod and an elastic member to open by a rotation thereof. The home bar door is rotated to be opened. A rotary member is rotatably installed in the casing, with oil contained therein to reduce rotating speed of the rotary member. An associated hinge shaft engages with the rotary member to rotate along with the rotary member.

A mobile radio communication apparatus includes a first housing, a second housing, a hinge part that foldably connects the second housing to the first housing, a one touch opening mechanism that is provided to the hinge part, and automatically opens the second housing from a folded state to an angle between 160° and 170° relative to the first housing in a non-stop motion, a damper mechanism that is provided to the hinge part and brakes an opening action of the second housing by the one touch opening mechanism, the damper mechanism including a damper having a rotational shaft that generates a braking power and a damper bush having a fixed shaft connected to the rotational shaft, and a flexible printed circuit that is twisted around the rotational or fixed shaft of the damper mechanism, and electrically connects the first and second housings to each other.
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.
