A guide system for guiding a door wing relative to a furniture carcass, the guide system including a guide configured to guide the door wing along a sidewall of the furniture carcass, and a carrier movably supported along the guide, the door wing being supportable on the carrier over a pivoting path between a first position and a second position. A drive device is arranged on the carrier or on a mounting member to be fixed to the carrier, and the door wing connected to the carrier in a mounted condition can be driven at least in a partial section of the pivoting path into the first position and/or into the second position by the drive device.

A low-bulkiness hinge for closing a closing element anchored to a stationary support structure, such as a wall, a frame or a floor includes a hinge body which includes a longitudinal operating chamber defining a first axis, a pivot coupled to the hinge body to rotate around a second axis between the opening and closing positions of the closing element, and a slider slidable in the operating chamber along the first axis. The operating chamber has a first seat for the pivot and a second seat for the sliding of the slider, which includes a shaft and an operative head that are mutually coupled. The hinge body has a first opening for inserting, perpendicularly to the first axis, the operative head into the second seat and a second through opening for inserting, coaxially to the first axis, the shaft into the housing. The hinge further has the shaft and the operative head fixed to one another after insertion in the second seat (so as to form a unitary assembly integrally slidable along the first axis.

A multi-link door hinge is proposed. The multi-link door hinge includes: a main body frame provided in a main body of an apparatus having a door; a door frame provided on the door; a body frame rotatably connected to one side portion of the main body frame; an inner link and an outer link rotatably connecting the door frame to the body frame; a leaf spring link rotatably connecting the main body frame to the outer link; an upper cam coupled to a portion connecting the body frame to the inner link in a co-rotatable manner, provided between first and second side portions of a sidewall of the inner link, and securely coupled to the body frame; an upper elastic member having a first side portion provided inside the inner link and a second side portion rollably coupled to the upper cam and elastically supporting the door frame.

A multi-link door hinge capable of facilitating the closing of a door and implementing the shock-absorbing performance of the door during the closing thereof. To this end, the multi-link door hinge includes: a main frame mounted to a main body of an object having a door; a door frame mounted to the door; a body frame rotatably connected to a first side of the main frame; an inner link and an outer link connecting the door frame to the body frame; a plate spring link allowing the outer link to be rotatably connected to the main frame; a locking piece rotatably mounted between side walls of the inner link; an elastic member; and a hook, a first side of which is fixed in the body frame and a second side of which is configured to be held in a second side of the locking piece.

Helical compression spring for use in an actuator for opening and closing a door or a tailgate of a car has an outer diameter between 15 and 50 mm and comprises a helically coiled steel wire. The steel wire has a non-circular cross-section with an equivalent diameter d (in mm) of the steel wire is between 1 mm and 12 mm. The cross-section may have at least two opposing parallel sides. The cross-section further has rounded edges, wherein the rounded edges have a radius of curvature ranging from 0.10 mm to 5.0 mm. The microstructure of the steel wire in the helical compression spring is cold deformed pearlite. In comparison with helical compression springs with round cross-sections, the non-round helical compression springs may occupy less space or reach higher breaking loads within the same space.

Hinge for the opening and the closing of hinged doors of furniture units, including a first fixed body designed to be housed in a seat of a horizontal plane of the structure of a furniture unit, such as a base or a top, and a second movable body designed to be housed in a seat of a door of the furniture unit, to actuate the door during opening and closing by way of a movement mechanism including at least one lever or connecting rod connecting a pin placed on the fixed part of the hinge and a pin placed on the movable part, wherein the closing force of the door is determined by a spring, the spring acting, with a tilting action, on an extension of the connecting rod beyond the hinge pin.

A multi-joint hinge has a mounting element which can be fixed to an appliance body and a hinge part which can be fixed to a door and which is held pivotably on the mounting element via a joint mechanism with a plurality of joint levers. The hinge part is biased in the closing direction via a spring and at least one linear damper with a damper housing and a piston rod displaceable relative to the damper housing is provided which brakes a closing movement of the hinge part. The linear damper is arranged with the damper housing in a rotationally fixed manner via a holding element within a lever and the holding element is fixed to a lever of the joint mechanism. The piston rod can be pushed into the damper housing via an actuating element which is arranged on a further lever of the joint mechanism.

An electronic device, including a host, a main display, an auxiliary display, and a lifting mechanism, is provided. The main display is pivoted to the host. The auxiliary display is disposed on the host. The lifting mechanism is disposed between the auxiliary display and the host. The lifting mechanism is configured to lift the auxiliary display and maintain a lifting height of the auxiliary display.
