PCT No. PCT/EP93/01387 Sec. 371 Date Jan. 10, 1994 Sec. 102(e) Date Jan. 10, 1994 PCT Filed Jun. 2, 1993 PCT Pub. No. WO93/25788 PCT Pub. Date Dec. 23, 1993A latch and lockset system comprises a common unit having a socket (30) that houses a rotor (40) pivotably supporting a catch (50) on a pin (53) and attached to latch means (handles 20, 22). As the lockset (10) is assembled, its components (50, 53, 40, 33/34, 23) 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 DEG to reach its idle position in which the handle (20) is biased 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-biased 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 ridge (45). |
