LOCKSET SYSTEM WITH A LATCH AND PROCESS FOR ASSEMBLING THEREOF

摘要

A lockset system with a latch comprises a common lockset (10) unit having a socket (30) that houses a rotor (40) pivotably supporting a catch (50) on a pin (53) and attached to handles (20). As the lockset (10) is assembled, its components secure themselves successively. The unit is mounted in a transversal bore (Q) of a door leaf (T) by introducing a handle (20) sideways so as to point outwardly towards the free door edge whereby the common unit becomes seated in the transversal bore (Q); then the handle main portion (24) is pivoted by 180° to reach its idle position in which the handle (20) is biassed by a returning spring block (34) on the rotor (40). A guide bush (18) radially screwed into the socket (30) for securing it in a longitudinal bore (L) receives a spring-biassed bolt (15). The catch (50) is an elbow lever reaching over a slanted ridge (45) between cheeks (48) of the rotor (40); a fork (52) is lockable to the inner bolt end (17), whereas a follower arm (54) engages a receiving hollow (46) of the ridge (45).
