Utility patent application 162423/1986 as a structure that made it impossible to read the key pile in conventional cylinder locks.
This is due to the shoulder 11 notched into the side of the tumbler.
At the same time, a stopper 12 is formed near the tumbler insertion opening in the tumbler groove corresponding to this shoulder. However, the stopper is formed by caulking the outer end of the tumbler groove inward, and the material is hard, so the dimensional accuracy is not stable. I had a problem with my work.

In the present invention, the upper shoulder 4 of the spring holder of the tumbler is brought into contact with the inner circumferential surface 9 of the cylinder as a means to make it impossible to decipher the key thread, and the arrangement of the rear end edge of the key hole is made relative to the key thread. This is characterized by preventing the key pile from being decoded through the key hole by preventing it from being arranged in an array.

The present invention is a cylinder lock in which a plurality of tumblers 7 are set via springs 3 in tumbler grooves 2 provided in multiple stages in a rotor 1, as shown in FIGS. 1 and 2. The upper shoulder 4 of the receiver 8 is formed into an arc shape that is almost the same as the inner circumference of the cylinder, and in the natural state where the tumbler 7 is biased toward the head side by the spring 3, the key hole 5 in the center of the tumbler is inserted from the shoulder 4. The dimensions up to the rear end edge 6 were made to be almost constant, that is, the positions of the rear end edges of the key holes of each of the plurality of tumblers were arranged on a straight line parallel to the axis of the rotor, as shown in Fig. 2. It is something.

In the cylinder lock according to the present invention, the positions of each tumbler in the natural state without a key inserted are between the upper shoulder 4 of the tumbler and the inner peripheral surface 9 of the cylinder.
Due to contact with the rear edge 6 of the keyhole as shown in Figure 2,
are located on a straight line parallel to the rotor axis. Therefore, even when looking at the arrangement of the tumblers from the key insertion slot, that is, the protruding state of the rear edge 6 of the key hole, they are all the same and straight, making it impossible to read the key threads.

This invention makes it impossible to decipher the key chain, and since the upper shoulder of the tumbler and the inner peripheral surface of the cylinder are in surface contact, there is no wear, it is stable, and it is easy to manufacture. Even if it hits, there is an advantage that the upper shoulder can be formed at the same time as the tumbler is punched out. Therefore, it does not require crimping work like conventional products, is inexpensive and has improved workability, and is useful for preventing theft of various articles equipped with cylinder locks, including automobiles.
