Abstract

The cylinder is surrounded by a case with a circular-sectioned head and laterally adjoining shaft, in the security lock. The cylinder (2) is centrally sited in the case head (3), and incorporates a key recess (5) with a guideway (14) for key insertion. The recess and key combine to form a circular profile, with axis (17) sited eccentrically in relation to the longitudinal axis (15, 16) of the head and cylinder. This can be built into European-type cases, with a high level of security, while the key is not easily copied, but is easily inserted.
