RETURN DEVICE FOR AN OPERATING MEMBER FOR A LOCK, ESPAGNOLETTE-LOCK OR THE LIKE

摘要

A return device (10) for an operating member engaged with a nut comprises a body (11) having on a front face arrangements which cooperate with complementary arrangements on the nut to convert rotation of the nut about its axis into longitudinal movement of the body. The ends of the body comprise respective pairs of branches (15, 16) forming forks extending in the longitudinal direction (D) of the body. The body (11) has a longitudinal opening (17) to accommodate a spring (18) open at both ends of the body (11) . The width (L) of the longitudinal opening (17) is greater than the distance (1) between the branches (15, 16) of the forks. The longitudinal opening (17) has at least one portion (17a) opening onto a rear face (19) of the body (11) and having the spring (18) passed through it. Uses include in a casing for a lock, espagnolette-lock or the like.
