Safety lock On the inner side of the plate crankcase (5) cylinders (1) for key are fixed and wheels (2) for decoding. In the cylinder (1) itself two parted bearings (8) are situated for the key. In the upper part of the bearing (8), through the slit (9) in shape of two concentric open circles rings (11) keys are inserted, which are toothed wheeled on ends. The rings (11) are inserted in the cylinder head (10) of the key. The cogs (12) are different height and length and pass through slits (9) on the upper part of the bearings (8) and slide through into the recess (13) in the lower bearing, fitting perfectly so that the key can turn and start the pointer (4) on the lock, having in mind that the wheels (2) for decoding are put in such a position that the lever (3) can without disturbance pass through them. |
