This invention discloses a door opener, comprising a shell consisting of an upper cover plate (1) and a lower cover plate (2). The key is that a pushing device for pushing the door to rotate is provided in the shell. An end of a driving device, which has one or more springs, can drive, via a rotating member (3), the pushing device to rotate. A locking/releasing device, which cooperates with the driving device, is provided at the other end of the driving device. The structure of this invention is unique. It allows the door to be conveniently opened and will not cause any possible harm to the users.

An adjustable force device comprises a member that is mechanically guided for allowing a displacement according to a predetermined trajectory, and means for magnetically indexing the displacement by the magnetic interaction between a first ferromagnetic structure and a second ferromagnetic structure integral with a magnet, wherein the magnet is at least partially surrounded by an electric coil that modifies the magnetization of the permanent magnet according to the direction and the amplitude of the electric current flowing in the coil.

An actuating drive includes an actuating arm pivotally supported about a pivoting axis, and movably supported between a closed position and an open position. A force storage member applies a force to the actuating arm, and a coupling device can brake or prevent a pivotal movement of the actuating arm. The coupling device includes a movably-supported first coupling element having a tooth arrangement, and the first coupling element can engage a second coupling element when a predetermined pivotal speed of the actuating arm is exceeded to brake or prevent the pivotal movement of the actuating arm. The second coupling element includes an engagement section for engaging the two coupling elements together, and includes a freewheel section separate from the engagement section. In the closed position, the first coupling element is within the freewheel section of the second coupling element, whereby the two coupling elements are decoupled from one another.

An apparatus for moving sliding doors and wardrobe doors fixed to the inner face of the top of a door includes at least one carriage and at least one braking device with a slider pulled by at least one coil return spring. The door is hung from a beam made up of two extruded profiles, the first of which is fastened to the wall with screws and relative plugs; the second extruded profile is fastened to the first profile with snap-in couplings. These coupled profiles define a cavity in which the braking device is housed and stabilised with screws, fixed on a cantilevered bracket of the second extruded profile. The latter defines a sliding track for the wheels or bearings of the carriage(s), fixed to the door at a recess.

A bidirectional damper comprises a mounting bracket, a tension spring, two damping cylinders and two engaging members; the mounting bracket comprises a first bracket plate, a second bracket plate and a connecting plate connected between the first bracket plate and the second bracket plate, the connecting plate comprises a main body section and extension sections at two ends of the main body section; the damping cylinder, the tension spring and the two engaging members are located between the first bracket plate and the second bracket plate, the damping cylinder and the tension spring are respectively arranged at two sides of the connecting plate, and the two extension sections are bent from the main body section towards the tension spring.

An aircraft panel system including a first panel, having a hinged coupling configured to couple the first panel to an aircraft structure, a second panel disposed adjacent to the first panel such that the first panel and the second panel together form cabin surface of an aircraft, and a latch mechanism configured to releasably couple the second panel to the aircraft structure, where the first panel is configured to pivot about the hinged coupling from a latched position to an actuation position to actuate the latch mechanism and cause a release of the second panel from the latch mechanism.

An exemplary modular hold-open device is configured for use with a door closer comprising a body, a pinion rotatably mounted to the body, and an armature connected with the pinion. The modular hold-open device is configured to be mounted to the door closer, to selectively prevent rotation of the pinion by exerting on the pinion a resistive torque in a door-opening direction, and to cease exerting the resistive torque in response to a door-closing torque on the pinion exceeding a threshold torque to thereby permit rotation of the pinion in the door-closing direction.

The invention relates to a movement assemblage, in particular for a drawer, a sliding door, a hinged door, a hatch, or a similar movable furniture part, having a push-out assemblage; the push-out assemblage comprising a guide element (90) on which an energy reservoir (80) acts; the guide element (90) being displaceable from a parked position into an ejection position; and a switching piece (99), which is displaceable with respect to the guide element (90), being attached to the guide element (90). For improved movement guidance, provision is made according to the present invention that the switching piece (99) comprises a guide element (99.4) that is guided in a guide track (74) of the fitting.
