The insertion state of the wire lock D is maintained by bringing the outer end portion 1 ′ into contact with the outer end surface.
Note that the inner peripheral surface of the boundary portion between the front end portion 5 and the rear end portion 6 of the sleeve A has an inner diameter appropriately larger than the inner diameter of the pipe B (handle portion), and is formed in a ring-shaped stop portion. A 'and a non-return step A ″ are provided in two steps, and the stop step A ′ restricts the fitting depth with the end B ′ of the pipe B (handle portion) to be constant, The check step portion A ″ functions to engage with a bulging portion 23 of a rubber elastic body 8 described later in the locked state of the cylinder lock mechanism 1 to prevent the wire lock D from moving backward.
[0010]
The cylinder case a housed in the pipe B as described above has a cross-section extending along the inner circumferential surface of the rear end portion 6 of the sleeve A in the circumferential groove 7 provided in the middle as shown in FIG. A rubber elastic body 8 having a tapered shape with a small inner end side and an annular shape is fitted, and the bottom of the circumferential groove 7 is rotated by a key 21, which will be described later, as shown in FIGS. A fitting hole 9 facing in the diametrical direction is provided corresponding to the operation angle.
Further, two rubber elastic bodies 8 fitted in the circumferential groove 7 correspond to the hole width of the fitting hole 9 in the diameter direction of the inner circumferential surface as shown in FIGS. The ridges 10 are integrally provided, and the ridges 10 are fitted into the fitting holes 9 as shown in FIG.
On the other hand, in the cylinder b fitted in the cylinder case a, as shown in FIGS. 2, 4 and 5, the gap between the fitting hole 9 is made equal to the position corresponding to the circumferential groove 7, A part of the peripheral surface is cut away so as to form a notch 12 so as to form a working portion 11 that is opposed in the diameter direction.
[0011]
As shown in FIGS. 1 and 2, the cylinder b has a repellent spring 15 fitted into a convex strip 14 having a spring fitting hole 13 at its inner end, and is biased by the spring 15 so that a wedge-shaped front is formed.

Along with the rise of the ridge 10 pushed up in the fitting hole 9, the elastic body 8 forms a bulge portion 23 as shown by an imaginary line in FIG. To do.
[0013]
The bulging portion 23 of the elastic body 8 is actually pressed against the inner peripheral surface of the rear end portion 6 of the sleeve A to hold the wire lock D in the storage position. At the same time, the wire lock D is prevented from coming off by engaging with the check step A ″ as described above.
In addition, when the cylinder lock mechanism 1 is in the locked state, the key 21 can be pulled out and can be carried in the same manner as in the case of the conventional lock mechanism. Further, description of the internal structure of the cylinder b such as a tumbler piece engaged with the key 21 is omitted.
[0014]
Next, an operation for taking out the wire lock D stored in the pipe B will be described.
First, in the state of FIG. 6A, a predetermined key 21 is inserted into the key hole 22 and rotated to the unlocked position.
When the cylinder b rotates following the unlocking rotation operation of the key 21, the push-up by the actuating part 11 is released, so that the annular elastic body 8 has its restoring force provided to itself (b in FIG. ), The protrusion 10 in the fitting hole 9 is lowered, the bulging portion 23 pressed against the inner peripheral surface of the rear end portion 6 of the sleeve A is eliminated, and the check step A ″ The inner diameter of the wire lock D is reduced from the sleeve A so that the wire lock D can be taken out of the pipe B.
[0015]
The wire lock D taken out of the pipe B and the sleeve D is in the unlocked state with the unlocking operation as described above. Therefore, it can be used as a normal wire lock regardless of the storage location. Then, the fingertips are put into the recesses 24 formed on both sides of the receiving seat 19 to hold the locking lever 3 and resist the elastic engagement between the recesses 20 and the protrusions 16 shown in FIG. When the free end of the wire 2 and the locking lever 3 are pulled upward, the wire 2 and the locking lever 3 are opened.
[0016]
Then, depending on the length of the wire 2, it is wound around an arbitrary object such as a front wheel and a front fork, a rear wheel and a rear fork, a pipe post and a standing tree, and the free end of the wire 2 and the locking lever 3 are again shown in FIG. Fit into seat 19 as shown.
In this embodiment, since the free end of the wire 2 and the locking lever 3 are connected to each other via a mounting shaft 3 'so as to be swingable, the winding when the wire 2 is wound around the locked object. The turning operation and locking operation can be performed relatively easily.
[0017]
Next, when the key 21 is turned to the locking position, the ridge 14 at the inner end of the cylinder b changes its angle by rotation and comes into contact with the protruding ends of the U-shaped slide lever 17 to compress and slide the repellent spring 15. Retraction of the lever 17 is prevented, and the key 21 can be carried while the locking lever 3 is maintained in the locked state.
[0018]
