- 30 - Abstract Magnetic Lock Insert for Lock Mechanisms The invention concerns a cylinder lock actuatable by means of magnetic bodies, which may be a single lock insert connected to the bolt carrier of the lock mechanism , or a lock consisting of two axially- symmetrically lock bodies surrounding the bolt carrier from two sides, the insert including an internal cylinder rotatable by a magnetic key between an open and a locked position. Latches in latch grooves formed at both sides of the cylinder are turnable together with the cylinder in the lock body. A line or series of rotors is arranged in respective notches of the rotor supports. The rotors are turnably journalled on shafts and have latch-receiving channels. In their wedged position, the latches prevent turning of the cylinder with a foreign object. The rotor supports and the rotor housing are recessed into the opposite sides of the cylinder surface. The cylinder has a locating pin provided with a catch or a steel ball for fixing the turnability of the lock body and the removal position of a proper key. The cylinder has bores into which tumblers of varying lengths for preventing cylinder rotation, the effective length of the tumblers being set by the steps of the key bit. Two control rings (29a, 29b) are arranged between the cylinder (2) and lock body (1) which are provided with latch grooves (9) receiving that part of the latch (8) which prevents cylinder (2) rotating. The rotor housing has a latch channel (11) formed along the chord of the - 31 - magnetic body (5) in the rotor (6) and can receive the other part of the latch (8) in a state of magnetic equilibrium determined by the magnets in the key (3) and the magnetic body (5). When a proper key (3) is fitted into the keyhole (10), the latch channel (11) is arranged partly in the rotor (6) housing and partly in the rotor support (4): in this position the cylinder is freely rotatable. When the proper key (3) is removed, the latch channel (11) in the rotor housing is outside the line of action of the latch (8), the latch (8) being arranged in the rotor support (4) and in the latch grooves (9) of the control rings (29a, 29b). The latch groove (33) assuring the locking position of the latches (8) is formed in the lock body (1) along the line of the latch grooves (9) of the control rings (29a, 29b). In a preferred embodiment, a shoulder formed on the side of a two-part lock bolt carrier (15a, 15b) fits into the groove formed on the end of cylinder (2), which shoulder surrounds the end of the cylinder (2). In another preferred embodiment, any of the two latch channels (100, 102, or 100, 103, or 100, 104, etc.) may form the latch channel of an individual or master or general key system, and a selection of the angular position between the latch channels (100, 102, or 100, 103, or 100, 104, etc.) and the relative positions of the instantaneous, variable magnetic fields represent the variation factors of the key or lock systems, the locking number of which rungs into the range of several millions.
