Bolt element and keeper for an espagnolette fitting

摘要

The locking pin (9) is fixed at one of its shaft (12) to the drive bolt (10) and at the free end of its shaft has a radial expansion (13) which seen in the longitudinal sectional view of the pin has a convex curvature (15) on its side facing the shaft. The radial expansion is spherical of lens-shaped. Independent claim describes closure for drive bolt fitment which has a locking pin and opposite this a locking plate (8) which has a dished guide (14) corresponding to the convex curvature of the radial expansion.
