摘要： A device for assisting the opening and closing of a door in a structure. The device may comprise: a door shaft configured to rotate about a longitudinal axis thereof in both a first direction and in a second opposite direction, and configured to be mounted to the structure to form a hinge about which the door may rotate in the both the first and second directions relative to the structure; a first actuator linked to the door shaft and configured to control a speed of rotation of the door shaft in the first direction; and a second actuator linked to the door shaft and configured to drive rotation of the door shaft in the second direction. The second actuator is an electromechanical actuator.

摘要： A shock absorber includes a first end configured to be mechanically fastened to a first component, a second end configured to be mechanically fastened to a second component, a main body, a main shaft, and a primary piston. The primary piston configured to move within the main body and further configured to provide a first damping force by movement of a fluid through the primary piston while the main shaft moves a first distance. The shock absorber also includes a deformable solid material arranged in the main body. The primary piston configured to further move within the main body and further configured to provide a second damping force by deforming the deformable solid material after the main shaft moves the first distance.

摘要： Disclosed are systems and devices for controlling the closing of a door. A head unit is to be installed in a doorjamb, comprising a chamber filled at least in part with a shear thickening fluid. A piston is connected to a cap and configured to exert pressure against the shear thickening fluid in response to a force applied to the cap. The systems and devices provide an adjustable design that resists door slamming and aggressive closure, serving as a safety device as well as noise, damage and pet control around doors (preventing closure if desired). An install kit provides exact location, depth control and guide to place over the head unit to tap it into place with a hammer.

摘要： This invention discloses a damping hinge that includes a first clamp plate and a second clamp plate, wherein one or more damping mechanisms are arranged on the first clamp plate and/or the second clamp plate. The damping mechanism includes a fixed pressure block, a movable pressure block which is able to move in the vertical direction, and a damper which is arranged vertically and has two ends connected to the fixed pressure block and the movable pressure block respectively. A first inclined surface of the movable pressure block is in abutting connection with a second inclined surface on the other clamp plate. This invention drived the damper to compress and retract vertically and improved the damping effect and service life of the damper.

摘要： A hydraulic door closer capable of reducing oil-pressure therein at high temperature, comprises a housing with an oil chamber, an oil storage cavity, and a piston in the housing of the hydraulic door closer. The oil storage cavity is in communication with the oil chamber; when the oil temperature increases, hydraulic oil in the oil chamber and oil storage cavity generates an increased oil pressure move the piston, whereby volume of the oil storage cavity is enlarged, such that oil from the chamber will flow into the cavity, to reduce the oil pressure of the chamber and cavity. When the oil temperature decreases, the oil pressure in the chamber and cavity is reduced, whereby the storage piston restores its original position, whereby volume of the cavity will be reduced, and the oil in the cavity flows back into the chamber. The pressure in the oil chamber is reduced when the hydraulic oil expands due to increased temperature to prevent failure of the seal and to avoid hydraulic oil leakage.

摘要： A slide rail assembly includes a first rail, a second rail, a base, an elastic member and a working member. The first rail is arranged with a positioning part. The second rail is movable relative to the first rail from a retracted position along a first direction and arranged with an engaging feature. The base is movably mounted to the first rail. The working member is rotatable relative to the base and arranged with an actuating structure. The actuating structure includes first and second parts. The second part is configured to be engaged with the positioning part, so as to allow the elastic member to accumulate an elastic force along a second direction. The first part is configured to be engaged with the engaging feature. The first part is arranged with a holding feature for preventing the engaging feature from being detached from the working member along a predetermined direction.

摘要： A damping device for the damping of the opening movement of a movable furniture part comprises: a fixed base unit with a furniture body of a piece of furniture; a movable base unit having the movable furniture part; and a damping unit comprising a first and a second damping component which are movable relative to one another when performing a damping function, of which the first damping component is arranged on the one base unit and as it approaches the movable base unit an impact takes place in the final position of said base unit between the second damping component and the other base unit, thereby triggering the damping function the first damping component is movably mounted on the allocated base unit such that on impact it can be displaced from a standby position into a working position supported by a stop in which the damping function can be performed.
