摘要 |
<p>The plug of a cylindrical lock includes at each side of its key channel a blind boring communicating with a conical recess in an arresting plate secured to the housing of the lock. The blind boring intersects cylindrical rotary control members arranged for rotation in the plug and each having a diametrical passage coinciding in one angular position thereof with the blind boring. A series of arresting balls is arranged in the blind boring and in respective passages in such a manner as to resume in the aligned position of the members a blocking position in which the terminal ball is in engagement with the conical recess. During the rotation of the plug by a correct key the arresting balls are shifted by the inclined surfaces of the conical recess into the blind boring and the plug is free to rotate. By the insertion of a wrong key at least one passage is misaligned and consequently the terminal arresting ball cannot be removed from its arresting recess.</p> |
