A pneumatic door closer includes a rotary energy-storing mechanism including a housing and a driving mechanism. The driving mechanism includes a cylinder, a second piston assembly and a sealing element, the sealing element is in an air tight connection with the cylinder and the second piston assembly, to form a closed space filled with high pressure gas in the cylinder. The second piston assembly drives the closed space into a first air chamber and a second air chamber in communication with each other. The driving mechanism also includes a first piston assembly connected to the second piston assembly. The pneumatic door closer also includes a transmission mechanism having one end received in the housing and another end connected to the door frame.

An actuation device for a lifting system for door leaves of furniture, the actuation device comprising a fixing plate that can be connected to the body of the piece of furniture, a supporting lever for the door leaf, which is connected, so that it can oscillate, to the fixing plate at a fulcrum and comprises, at the fulcrum, a connecting portion that extends eccentrically with respect to the fulcrum, and elastic means that comprise a body for accommodating at least one elastic element.

Pivot door hinge, including a hinge housing for mounting the pivot door hinge to a door, a pivot axle pivotally supported within the housing, the pivot axle having an end arranged for rotationally anchoring the pivot axle to a structure holding the door, a closing mechanism arranged within the hinge housing, the closing mechanism being cooperatively connected to the pivot axle, the closing mechanism being arranged for providing a closing torque in an angular position range of the door hinge relative to the pivot axle, the angular position range corresponding with a door in an open state. The pivot door hinge further includes a braking mechanism arranged within the hinge housing, cooperatively connected to the pivot axle, the braking mechanism being arranged for providing braking action in the angular position range of the door hinge relative to the pivot axle with a braking-angle profile.

A hinge mechanism comprising first and second members rotatable relative to one another about a hinge axis from a first to a second position; and a biasing arrangement operative to adopt an active mode to bias the first and second members into at least one relative position and operative to adopt an inactive mode where the biasing arrangement does not provide bias to the first or second members to undergo relative rotation, wherein the biasing arrangement remains in the inactive mode on relative rotation of the first and second members through a first selected angular displacement between the first position and the second position, and is in the active mode on relative rotation of the first and second members through a second selected angular displacement between the first position and the second position.

A laundry treating appliance for treating laundry items according to an automatic cycle of operation can include a cabinet defining an interior and having a top panel that at least partially defines an access opening to the interior. A lid is rotatable between a closed position and an opened position to selectively open or close the access opening. At least one hinge assembly couples the top panel with the lid. The at least one hinge assembly can include a lid hinge coupled to the lid and defining an axis of rotation of the lid. A hinge housing is coupled to the top panel and to the lid and configured to receive the lid hinge. A damper housing has a damper receiving portion, with a damper at least partially received within the damper receiving portion.

A door hinge device comprises a hinge base and an auxiliary door-closing mechanism mounted on a door and fitted with the hinge base. The auxiliary door-closing mechanism comprises a shell, an elastic member for driving the door to be automatically closed during the door closing process, a sliding member, and a guiding member for guiding the sliding member to move in the deformation direction of the elastic member during the door opening and closing process. One end of the elastic member is connected to the shell, an accommodating part for accommodating the sliding member when the door is in a closed state and a guiding bevel obliquely extending forwards to approach the auxiliary door-closing mechanism are arranged on the periphery of the hinge base in a concave manner, and the sliding member is in a compressed state when moving along the guiding bevel.
