Title
(EN) ELECTRIC LATCH MECHANISM
(FR) MÉCANISME DE SERRURE ÉLECTRIQUE
Abstract
(EN)
An exemplary latchbolt assembly includes a latchbolt, a locking sleeve, and a roller engaged between the latchbolt and the locking sleeve. The latchbolt is configured to drive the roller from a first position to a second position as the latchbolt moves from a projected position to a depressed position. The locking sleeve includes a blocking surface and a recessed portion. When the blocking surface is aligned with the roller, the locking sleeve retains the roller in the first position, thereby retaining the latchbolt in the projected position. When the recessed portion is aligned with the roller, the locking sleeve permits movement of the roller from the first position to the second position, thereby enabling depression of the latchbolt.
(FR)
Selon un mode de réalisation donné à titre d'exemple, cette invention concerne un ensemble pêne demi-tour, comprenant un pêne demi-tour, un manchon de verrouillage et un rouleau en prise entre le pêne demi-tour et le manchon de verrouillage. Le pêne demi-tour est configuré pour entraîner le rouleau d'une première position à une seconde position à mesure que le pêne demi-tour se déplace d'une position saillante à une position en retrait. Le manchon de verrouillage comprend une surface de blocage et une partie évidée. Lorsque la surface de blocage est alignée avec le rouleau, le manchon de verrouillage retient le rouleau dans la première position, retenant ainsi le pêne demi-tour dans la position saillante. Lorsque la partie évidée est alignée avec le rouleau, le manchon de verrouillage permet le déplacement du rouleau de la première position à la seconde position, ce qui permet le retrait du pêne demi-tour.
