Abstract (en)
[origin: WO2017017702A1] The invention refers to a lock strike plate which can be coupled to a lock of a device for locking a landing door of an elevator platform. The lock strike plate comprises a bolt bushing in which the bolt of said lock is at least partially housable. The lock strike plate also comprises an emergency unlocking system including a cam rotatable by means of an unlocking triangle and integrally con- nected to a tooth for ejecting the bolt from the bolt bushing. In particular, the cam is rotatable between at least one first position at which the ejection tooth lies outside the bolt bushing, and a second position at which the tooth is at least partially housed in the bolt bushing, determining the ejection of the bolt from the latter and consequently the unlocking of the door. A variant of the lock strike plate, object of the invention, comprises an apparatus including an electrical contact which can be actuated by means of a button type switch. The cam is in- tegrally connected to a second tooth which, with a rotation of the cam such to determine the ejection of the bolt from the bolt bushing, presses the button ac- tuating the electrical contact. This causes the positive stop of the movement of the car of the elevator platform. Another object of the invention is a device for locking a landing door of an elevator platform comprising a lock coupled to the lock strike plate, object of the invention.
