Abstract:
A door hinge for recessed installation between an edge of a door panel and a door jamb has first and second leaf assemblies that each form a cavity and are recessed in the door-panel edge and in the door jamb and a pair of U-section links pivoted centrally together about a center axis and each having a first end and a second end engaged in the cavities of the respective first and second leaf assemblies. The first end of one of the links and the second end of the other link are pivoted about respective vertical axes fixed in the respective leaf assemblies and the second end of the one link and the first end of the other link are pivotal about another respective vertical axis and horizontally shiftable in a respective guide of the respective leaf assemblies.
Abstract:
A vehicle interior trim component hinge assembly includes a rotatable component, and a shaft disposed through the rotatable component. The hinge assembly also includes a first friction disk rotationally coupled to the shaft, and a second friction disk rotationally coupled to the rotatable component. The hinge assembly further includes a biasing member configured to urge the first and second friction disks toward one another to establish a friction force that provides resistance to rotation of the rotatable component about the shaft.
Abstract:
A dual-axis hinge structure and electric device having the same are provided, and the dual-axis hinge structure includes a hinge base having a pushed portion, a first pivot portion having a first cam and a first shaft, a second pivot portion having a second cam and a second shaft, and a restoring member connected both the first pivot portion and the second pivot portion. The first shaft is pivoted on the hinge base, and the first cam is fixed on the first shaft, and the first cam is contacted with one lateral side of the pushed portion. The second shaft is parallel to the first shaft, and is pivoted on the hinge base, and the second cam is fixed on the second shaft, and the second cam is contacted with another lateral side of the pushed portion.
Abstract:
A door closer including a free-swing function, including a door closer housing, an output shaft connected to a door, a piston assembly connected to the output shaft and guided in the door closer housing, a closer spring, a piston rod adapted to connect the piston assembly to the closer spring, a free-swing assembly adapted to enable a translational motion of the piston assembly decoupled from the closer spring when the closer spring is locked, and a hydraulic lock compartment adapted to lock the closer spring. The output shaft is a cam-shaped rolling contour, in particular a cam disc, and the piston assembly includes at least one cam roller abutting on the rolling contour.
Abstract:
An improved top pin assembly is provided for a traffic door which integrally is provided with a hold open device for maintaining the door in either one of opposite fully open positions.
Abstract:
A transversely movable hinge is mounted between a base and a cover of a folding device and has a moving assembly. The moving assembly is connected to an expansion device via a linking rod. Therefore, when the folding device is opened, the expansion device is driven to extend and is convenient for users. When the folding device is closed, the expansion device is driven to retract for saving space.
Abstract:
A power boost assembly is disclosed that can be used with a door actuator, such as a door closer. The power boost assembly is structured to store an energy during a first movement of a door and release the stored energy during a second movement of the door. In one form the power boost assembly can be structured as a module that can be added to an existing door and door closer installation. In one form the power boost assembly is used to increase a closing force imparted to a door to ensure a latching event.
Abstract:
A concealed door hinge has first and second leaf assemblies fittable into respective mortises in an edge of the door and in the door frame. The first leaf assembly has a body, mounting tabs at ends of the body and securable to the door frame or to an edge of the door, and an insert shiftable in the body in a first horizontal direction perpendicular to a face of the assembly. The body is also shiftable relative to the tabs in a second horizontal direction transverse to the horizontal direction and parallel to the face. A swivel mechanism is connected between the second leaf assembly and the insert of the assembly. Adjusters engaged between the insert, the body, and the tabs can relatively secure the insert and body in any of a plurality of positions offset relative to one another in the horizontal directions.
Abstract:
The device (1) for decelerating the rotation of a hinge in particular for furniture, comprises a container (4) accommodating at least one rotating friction element (16) adapted to slide on a friction surface (17), a slider (18) moveable along a translational direction during the rotation of the hinge, and kinematic means for transforming the translation of the slider (18) into a rotation of the at least one friction element (16), the slider (18) having first means for receiving its movement during the opening of the hinge, distinct and separated from second means for receiving its movement during the closure of the hinge, the kinematic means comprise a drawing element (20) integrally joined to the slider (18) and permanently confined inside the profile of a cam (21) provided for on the friction element (16), the drawing element (20) being selectively engageable with a first section of the profile of said cam (21) for rotating the friction element (16) during the opening of the hinge or with a second section of the profile of the cam (21) for rotating the friction element during the final phase for closing the hinge
Abstract:
A hinge wing includes a cup intended for being fixed in a hole of a furniture component. The wing is provided with a pair of expandable teeth arranged on opposite sides of the cup. The teeth are fixed on an eccentric lever of the wing, by rotating which the teeth are moved in an opposite direction to the direction of insertion of the cup into the respective receiving hole. The wing includes for each tooth a cam that, upon rotation of the eccentric lever, causes the respective tooth to expand against a side wall of the receiving hole of the cup to fix the cup to the furniture component. Each cam is formed with a cam element of yieldable material interposed between a side wall of the cup and the respective tooth.
