Abstract:
[Object] To provide a one-way valve and a door check apparatus which is compact and includes a small number of components.[Means for Resolution] A one-way valve having a conduit for allowing liquid to flow therein, a valve element 21 provided in the conduit, a hole portion 7a provided in the conduit on the upstream side of the valve element 21 and configured to be brought into a closed state by being closed by the valve element, and a spring (urging means) 29 that urges the valve element 21 in the direction to close the hole portion 7a, in which the peripheral surface of the valve element 21 is formed with a first surface 21d and a second surface 21e intersecting the direction of movement of the valve element and generating a component force in the direction to close the hole portion 7a when an urging force of the spring 29 is applied, the first surface 21d and the second surface 21e are formed so as to increase the component force in the direction to close the hole portion 7a as the valve element 21 approaches the hole portion 7a, and the spring 29 constantly presses the first surface 21d and the second surface 21e from the direction intersecting the direction of movement of the valve element and constantly applies an urging force to the valve element 21 in the direction to close the hole portion 7a.
Abstract:
The invention relates to an actuating device for moving a flap of a piece of furniture, including at least one actuating arm for moving the flap, a base member on which the actuating arm is pivotally arranged, and a spring device able to act upon the actuating arm. An assembly securing device for the vacant actuating arm, which has not yet been fitted with a flap, includes a braking device which limits the opening speed of the vacant actuating arm.
Abstract:
A decelerating device intended to intercept an end-of-stroke part of a closing path of a mobile member, such as a furniture drawer or door, including: a body fastenable in use to an abutting surface for the mobile member and internally defining a sealed chamber filled in use with a viscous fluid; a pushrod at least in part overhanging from the body and being adapted to cooperate in use with the mobile member, the pushrod being integral with a stem slidingly accommodated in the body against the bias of elastic means between an extracted position of the pushrod and a retracted position; and a piston accommodated in the sealed chamber so as to divide it into two portions hydraulically connected to each other and mechanically connected to the stem; wherein the stem presents a first end integrally connected to the pushrod and a second end opposite to the first, both slidingly accommodated in the body outside the sealed chamber and fluid-tightly towards the sealed chamber itself; the piston is provided with a mobile sealing member to choke the hydraulic communication between the two portions of the sealed chamber only during the stroke of the stem towards the retracted position.
Abstract:
A damper assembly includes a fixed rack gear, a rotary gear damper having a gear engaged with the rack gear, and a tether movable with the damper along the rack gear and connected to the movable object to be controlled by the damper. A biasing element normally urges the damper away from anti-rotation locking members.
Abstract:
Universal impact-hinder device, comprising a body (1); a guiding pin (4) arranged at the closed first end of an inside cylindrical cavity of the body (1), a spring (7) on the guiding pin (4); a ring (5) at the opposite end of the cavity; and a piston having T-shaped head and an inside cavity in which the spring (7) is supported, which piston can move until the ring (5), while the guiding pin (4) is within the inside cavity of the piston. The T-shaped head is provided with a groove and a movable O-ring (6) within that, having two end positions in the groove. In first end position a surface of the groove having artificial damages (31) and the contacting O-ring (6) determine a first flow-through capacity, in second end position an orifice (21) between the cavity of the body and the groove determines a greater second flow-through capacity.
Abstract:
A hinge includes a housing. A sliding cam slideably received in the housing defines concave portions and an axial hole. A rotatable cam mating with the sliding cam has a base portion extending downward to form pushing portions disposed in the concave portions. The base portion defines an accommodating hole. A spring is slideably received in the housing. One end of the spring is fixed on the sliding cam and the other end of the spring is fixed at an end of the housing. A shaft received in the housing runs through the axial hole and the spring. An end of the shaft is received in the accommodating hole, and the other end of the shaft passes through the end of the housing. A first stop has a bottom surface whose part extends downward to form a blocking portion, and the rest part of the bottom surface is defined as a revolving platform. A second stop engaging with the rotatable cam has a top surface protruding upward to form a pushing block rotatablely disposed on the revolving platform. And a cap rotatablely receives the first stop and the second stop.
Abstract:
In a damping mechanism for a pivot door arranged in a door frame, comprising a door fixture arranged in or on the door panel, a frame fixture arranged in or on the door frame, a damper arrangement arranged in the door fixture or the frame fixture and a damper arrangement counter part mounted in the frame fixture or in the door fixture, a damper arrangement with a brake catcher provided with a damper member includes a spring element which pulls the brake catcher into the fixture and the damper arrangement counter part includes at least one trigger element which is abutted by the brake catcher during closing of the door, so that the damper arrangement begins to dampen the pivot movement of the door as soon as a fixture part of the door comes into contact with a fixture part of the door frame.
Abstract:
An actuating-arm drive is provided for cupboard doors. The drive includes an actuating arm that is hinged to a door and is subjected to the action of a spring. The actuating arm can be tilted over a pivoting area that is delimited by two end positions. The actuating-arm drive is equipped with at least one damper that damps the tilting motion of the actuating arm before the arm reaches either of the two end positions.
Abstract:
An example furniture hinge includes a saddle supporting the damping cylinder that engages a first mounting edge of the supporting arm from behind. A locking element supported movably on the saddle has a laterally protruding mounting lug, which in a locking position engages a second mounting edge of the supporting arm from behind. The second mounting edge is oriented counter to the first mounting edge.
Abstract:
An active break release device driven by a second motor and externally attached to the door controller, which is used for the triggering of automatic brake releasing to close the safety door in unexpected electricity failure condition, in which the door controller have a housing for receiving a first motor, the driving torque of which is transferred through a rotary shaft to a reel for winding the door; a braking device is provided at the outside of said rotary shaft, which includes a braking portion normally located at a brake activating position, and located at a brake releasing position when the first motor is energized, characterized in that the active break release device comprises: at least a brake releasing rod, one end of which activates the braking portion to release braking by leverage action force, while the other end of which extending to the outside of the door controller; at least a second motor, provided externally at the door controller and moved together with the other end of the brake releasing rod; a circuit having a backup power source used to temporarily supply electricity to the second motor in case of unexpected electricity failure condition, so that the braking portion being driven to release braking. In this manner, the braking can be automatically released at the first instant of electricity failure so as to close the safety door.
