Abstract:
A knob device (10A) for opening by pressure action doors and the like provides a knob (11) which is adapted to be rigidly secured to the door, a control member being movably mounted on the knob and associated with, inside the knob, a main lever (14) operating on a mechanism (40-45) which is adapted to operate a bolt elastically sliding into a door housing; in order to reduce the stress exerted to control the door opening, and in order to have a large surface on where pressure can be exerted, the control member comprises a levering member acting upon said main lever (14) in order to operate* said mechanism.
Abstract:
The invention relates to a locking device (100) for doors (101, 102) particularly sliding glass doors and the like, comprising: a lock unit (2) to be controlled by a key (20) such as to lock the doors in a closed position and unlock them to allow the relative motion thereof, fastening removable means (1) to at least one of the doors suitable to support the lock unit (2) and mechanically cooperate with the same to lock the doors in said closing position. The device is characterized in that said fastening means are provided with at least one elastically yielding element (12) intended to act on a surface of said at least one door to reduce the backlash between the surface and the fastening means and avoiding that the surface may be damaged while assembling and removing the fastening means.
Abstract:
A body (14) of the electric lock, embedded in a jamb of a fixed frame, contains an electromechanical release device comprising a loading bolt (28) suitable to be retracted in the body (14) . A pusher (34) is movable between a retracted position in the body (14) and a forward position in a selvage (26) to expel from the selvage (26) the nose (20) of the lock and release the latter. There are provided elastic means (52) for the pusher (34) to be returned to the forward position. An escapement system (44) is suitable to hold the pusher (34) at the retracted position. A kinematic mechanism (46) interlocks the loading bolt (28) and the escapement system (44) such that, when the loading bolt (28) is caused to retract, the pusher (34) is held at the retracted position by the escapement system (44) ; when an electromagnet (42) is excited, the escapement system (44) releases the pusher (34), which is snapped to the forward position to expel the nose (20).
