WIPO Patent Application WO/1995/018282
Kind Code:
A1
Abstract:
A cylinder lock and key combination, wherein the lock comprises a side profile ridge (60) disposed in the key slot (53) and having relatively shallow recesses (61), in which a projection (55) on a side tumbler (54) is vertically movable, and a continuously extending edge portion (62). The key has a relatively shallow coded groove (17), which cooperates with the side tumbler projections (55) of the lock, and a rectilinear, deeper profile groove (16), into which the edge portion (62) of the side profile ridge fits. This unitary edge portion secures a good guidance of the key when the latter is inserted into the lock.
