Abstract:
A piston device for the controlled rotatable movement of a closing element (D) anchored to a stationary support structure (W) including a tubular body (10) removably insertable into at least one seat (S) of a hinge device (H), an actuating head (20) external to the tubular body (10), a plunger member (30) slidably movable unitary with the actuating head (20) between a retracted end position and an extended end position, elastic contrast means (50) acting on said plunger member (30) for the returning thereof from the retracted end position to the extended end position and a working fluid acting on the plunger member (30) to hydraulically counteract the action thereof. A hinge device in which the piston device is removably insertable.
Abstract:
A damped hinge comprising: a first leaf (32) for securing the hinge to a fixed support; a second leaf (35) for securing a moveable closure to the hinge; a barrel (33) secured to the first leaf (32), the barrel (33) including an axial bore (34); a piston (30) mounted for axial movement within the bore (34), the piston (30) including a cam surface (45); an axially extending member (39) constrained to rotate with the second leaf (35), the member (39) including a cam follower (42) arranged to engage the cam surface (45); the cam surface extending axially so that the piston (30) moves axially within the bore as the second leaf is rotated in relation to the first leaf; a hydraulic fluid contained within the bore (34); at least one of the piston (30) and member (39) including a passageway through which the hydraulic fluid may flow as the piston moves within the bore; wherein the passageway includes an adjustable valve (48, 49) to restrict the flow of fluid to damp opening or closing of the hinge.
Abstract:
Die Erfindung betrifft ein Regulierventil (1), das insbesondere in eine mit einem Innengewinde (41) ausgeführte Bohrung (40) eines hydraulischen Türschließers (11) befestigbar ist, mit einem Grundkörper (2), an den sich ein Regulierbereich (3) anschließt, und einem Gewinde (6) mit einer Verdrehsicherung, wobei das Gewinde (6) mit der Verdrehsicherung in das Innengewinde (41) der Bohrung (40) eingeschraubt wird. Um ein Regulierventil (1) zu schaffen, das einfach gestaltet ist, wobei ein ungewolltes Verstellen des Regulierventils (1) während des Betriebes ausgeschlossen ist, wird vorgeschlagen, dass die Verdrehsicherung einen erhabenen Bereich (7) aufweist, welcher mit der Bohrung (40) oder dem Innengewinde (41) des Türschließers (11) zusammenwirkt.
Abstract:
The invention relates to door closers, particularly a door closer control device that regulates the flow of a pressure medium controlling the function of a door closer. A control device according to the invention includes a support part with a collar that serves as a second support for the control device on the door closer body in addition to the support in the guiding part. This second support holds the control device in place within the pressure medium flow without any rocking or swaying movement, which would hamper the door closing speed.
Abstract:
PURPOSE: An automatic door closer unit is provided to conveniently control the closed speed of a door, and to prevent oil from flowing out when the door closer unit is powered. CONSTITUTION: An automatic door closer unit(1) comprises a main housing(10), a spiral spring(30), a damper housing(50), a movable shaft(70), and a cover(90). The main housing is installed in a door. The bottom of the main housing is closed. The spiral spring supplies restoring force to the movable shaft when the door is closed. The damper housing divides the main housing into an upper chamber(10b) and a lower chamber. One end of the movable shaft is extended to outside through the cover, and the other end is rotatably supported by the bottom end of the main housing. The cover is fixed to the top of the main housing.
Abstract:
A refrigerator according to the present embodiment comprises: a cabinet having storage spaces; a main door, which can rotate with respect to the cabinet and opens/closes the storage spaces; a sub door rotating with respect to the main door; and a hinge device, which is fixed to the front surface of the cabinet, supports the lower sides of the main door and the sub door and provides the center of rotation of the main door and the center of rotation of the sub door, wherein the center of rotation of the main door and the center of rotation of the sub door can be positioned on the sub door.
Abstract:
A door opening structure for microwave oven includes an upper hinge fastened on a door body assembly, and a lower hinge fastened on a oven body of a microwave oven, wherein the door body assembly is hinged with the oven body by the upper hinge and the lower hinge. An elastic element is provided between the upper hinge and the lower hinge, and the upper hinge is connected with a damper. Both ends of the upper hinge are provided with first connectors that are hinged with the lower hinge, and the middle portion of the upper hinge is provided with second connectors that are hinged with one end of the damper by spring pins.
Abstract:
A door closer assembly is provided, including a valve regulating an amount of hydraulic fluid that flows through the valve. The amount of hydraulic fluid flowing through the valve controls a force generated by the door closer assembly on a door. A first sensor measures an angular position of the door, and a second sensor measures an angular position of the valve. The angular position of the valve determines the amount of hydraulic fluid flowing through the valve. A controller controls the adjustment of the valve based on the angular position of the door and the angular position of the valve.
