A locking device having a guard lock for safety doors includes a mechanical actuator which can be fastened on a movable door part and a housing which interacts with the actuator and can be fastened to a door counterpart. The housing includes a receptor to which the actuator can be inserted, and the housing comprises a locking element which is displaceable between an unlocked position, in which the actuator can be released, and a locked position, in which the actuator can be fixed relative to the receptor. The actuator comprises an engagement tongue having an engagement recess for mechanical operative engagement with a head end of a locking element in form of an engagement plunger, the engagement plunger being guided in the housing so as to be longitudinally displaceable in a spring-biased manner in the in a plunger longitudinal direction relative to an inner fixed bearing.

An appliance includes a hinge module between a main body and a pull-down door. The hinge module includes a housing, a rotational axis member disposed in the housing serving as a center of rotation between the pull-down door and the main body, an inner link housing movably disposed in the housing that moves with the opening of the pull-down door in a direction of the rotational axis member, and a damper installed in the inner link housing, the damper including a piston and a cylinder and providing damping force according to a relative movement of the piston and the cylinder. Any one of the piston and the cylinder of the damper moves with the inner link housing and the other of the piston and the cylinder of the damper moves by a predetermined distance as the inner link housing moves and then is interfered by the housing so as not to move further, and the piston and the cylinder of the damper starts damping, wherein the predetermined distance corresponds to an opening angle of the pull-down door in which the damping is started.

A door-lock for household appliances, comprising a casing (12) having an opening (14) for the insertion of a hook (15) carried by a door of said household appliance, a cam (16) rotatable relative to the casing (12) about a first axis (A) between a retaining position and a release position, wherein in the retaining position said cam (16) is adapted to lock said hook (15) in a closed door position, a locking slider (20) cooperating with said cam (16) and movable between an unlocking position and a locking position, wherein in the locking position the slider (20) locks the cam (16) in the retaining position, a locking pin (28) for locking the locking slider (20) in the locking position, a door sensing slider (32) movable between an open door position and a closed door position, the door sensing slider (32) having an abutment portion (36) including a top surface (38) and an inclined surface (40) and a door sensing pin (46) elastically biased against said abutment portion (36) of the door sensing slider (32), wherein in the open door position of the door sensing slider (32) the door sensing pin (46) is in contact with said top surface (38) and in the closed door position of the door sensing slider (32) the door sensing pin (46) is in contact with said inclined surface (40).

An anti-burglar bar (1) for rolling shutters (2) or rolling gates, which are defined by a plurality of horizontal slats (3) associated with a winding roller and are slidable in a first and a second vertical guides (4,5) opposite to one another, comprises electromechanical control means (7) of a first and a second blocking elements (8) and (9), arranged slidingly in a body (11), which engage respectively in a first and a second retention blocks (10) associated with said first and second guides respectively, a first and a second feelers (12) being provided which engage respectively with a first and a second position sensors (13) for transmitting an electric signal, said electric signal activating said electromechanical control means (7) only when said first and second feelers (12) are simultaneously aligned with said first and second position sensors (13) respectively.

A latch assembly for an appliance includes a cabinet having a front panel with a latch opening. A latch member is aligned with the latch opening of the front panel and is movable between an engaged position and a disengaged position. A door is hingedly coupled to the cabinet between open and closed positions and has a latch receiving aperture. A cover plate is configured to selectively cover the latch opening. The cover plate is rotatably coupled with the cabinet between first and second positions.

A domestic electrical appliance includes an appliance main body having an access opening to a usable chamber formed inside the appliance main body, and a door which is movably mounted on the appliance main body and which in an open position frees the access opening and in a closed position closes the access opening, a door latch for holding the door closed in the closed position, and a door opener, structurally separate from the door latch, for opening the closed door. The door opener includes a first coupling structure displaceably arranged on one of the appliance main body and the door, an electrically controllable drive unit for driving the first coupling structure, and a second coupling structure arranged on the other of the appliance main body and the door.
