A hinge for doors of domestic appliances, comprising a first element and a second element pivoted to each other and movable relative to each other in tilting fashion, the first and second elements being fixable one to a frame and the other to a door of an electrical household appliance, for making the door movable with respect to the frame between a dosed position and an open position, a lever for connection between the first and the second closing elements, an elastic element connected to the lever and designed to generate with its own deformation a force of elastic adjustment designed to compensate at least partially the weight force of the door during the opening or closing of the door, means for adjusting the intensity of the elastic reaction force.

Provided is a damping hinge for controlled closing of a door or gate. The damping hinge includes a first clamp plate configured to be mounted to a fixed supporting panel; a second clamp plate configured to be mounted to a panel of the door or gate, wherein the second clamp plate is connected with the first clamp plate for relative rotation about a hinge axis; and a damping mechanism arranged on at least one of the first clamp plate and the second clamp plate including a damper arranged substantially parallel to the hinge axis and configured to impact relative rotation of the second clamp plate towards the first clamp plate during closing of the hinge. The damping mechanism may be arranged such that the damping mechanism may be located outside of a plane of the respective panel and adjacent or next to an outer or facing surface of that panel.

A hold-open arrester arrangement has a low power consumption, and therefore a battery lifetime is long in the embodiments of the invention utilizing the battery. The hold-open arrester arrangement has a hold-open arrester arrangement having a hold-open function to hold a door open. The arrangement has also an electric release arrangement. The release arrangement is arranged to release the hold-open function in a fire alarm situation. The hold-open arrester arrangement comprises a sliding block and an arrester unit. The sliding block is connectable with a slide rail in a sliding manner and also pivotable connectable to an arm of a door closer. The arrester unit is connectable to the slide rail and has a body, said electric release arrangement, and said hold-open function with the sliding block.

A furniture drive includes a carrier and an actuating arm assembly arranged on the carrier and including a movably-supported actuating arm. The furniture drive also includes a spring device for applying a force to the actuating arm assembly, the spring device being connected to the actuating arm assembly via an engagement location, a transmission mechanism for transmitting a force of the spring device to the actuating arm assembly, and an adjustment device including a rotatably-supported adjustment element. A relative position of the engagement location can be adjusted by a rotation of the adjustment element. The furniture drive further includes an overload safety device configured to couple the adjustment element with the transmission mechanism upon rotation of the adjustment element with torque below a predetermined torque, and to decouple the adjustment element from the transmission mechanism upon rotation of the adjustment element with torque above the predetermined torque.

A negator spring tool for winding a negator spring output drum around a rotational axis includes: a pair of tool handles; and a tool disk having an outer edge which is generally circular except for a cutout. The tool disk is configured to be releasably attached to the output drum. The tool disk has a drum-facing side which includes protruding teeth protruding from the drum-facing side to engage radial spokes of the output drum. The outer edge of the tool disk includes handle slots which are spaced circumferentially. The distal end of each tool handle is insertable into a handle slot to rotate the tool disk around the rotational axis. The protruding teeth of the tool disk each having a T-shaped cross section, each T-shaped protruding tooth and the drum-facing side forming an I-shaped cross section having two opposite facing cavities on two opposite sides of the I-shaped cross section.

A door operator including an output shaft, a ball screw, a powered driver, and a yoke. The output shaft is configured to be coupled to a door. The powered driver is operatively coupled to the ball screw and configured to rotate the ball screw in a first rotational direction. The yoke is coupled to the ball screw and configured to translate in response to rotation of the ball screw. The yoke is configured to rotate the output shaft.

A furniture drive includes a housing which can be arranged on a furniture panel, an actuator arm movably mounted relative to the housing and to which a movable furniture part can be secured, a force accumulator device which can be used to exert a force onto the actuator arm, an adjustment device for adjusting the force which can be exerted onto the actuator arm by the force accumulator device, and a display device which can be used to display a force setting that can be perceived by the adjustment device. The housing has a support surface to bring the furniture drive into contact with the furniture panel, the housing has a housing face oriented transversely to the support surface, and the display device is arranged relative to the housing face such that the display device can be read in a viewing direction facing the housing face.

A compact, easily mountable door closer, particularly suited for use in cubicles provided in public washrooms, has a pivot member mounted substantially within a hollow body but has a section projecting from the body from which a door is, in use, suspended. A biasing element is provided to bias the pivot member toward a neutral position coincident with the door being closed. As the door and thus the pivot member is displaced away from the closed or neutral position to a defined angle, the biasing element and pivot member engage to provide a limit or fully open position.
