〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The locking mechanism of the present invention comprises one locking mechanism body 1, a lower locking lid 2 and an upper locking lid 3 which are fitted and locked in the locking mechanism body.
It is composed of a combination of two locking lids.

On the surface of the lock mechanism main body 1, fitting holes 11 and 12 for detachably fitting and locking the lower locking lid 2 and the upper locking lid 3 are formed in two steps, upper and lower.

The lower locking lid 2 is attached to the tip of the locking string 4 housed in the lock mechanism main body 1 so as to be freely extended and wound up. The locking projection 21 provided on the back side is fitted into the fitting hole 11 located above the two fitting holes 11 and 12 formed in the locking mechanism main body 1 so as to be juxtaposed vertically. It is locked.

In addition, it is desirable that the fitting hole 11 is formed so that its depth is slightly deep so that the entire lower closing lid 2 can be fitted into the stopper (see FIG. 1).
The upper surface of the outer closing lid 2 fitted in the fitting hole 11 can be configured to be flush with the upper surface of the lock mechanism body 1 (being in a flat and horizontal state). The upper closing lid 3 which is mounted on the upper surface so as to cover it has a fitting hole.
It becomes possible to perform fitting with respect to 12 while maintaining an accurate and horizontal state.

The upper locking lid 3 is formed to have a size capable of abutting from the upper surface of the lower locking lid 2 and covering the lower locking lid 2 described above. It is to be fitted into the fitting hole 12 formed in.

The locking projection 31 fitted in the fitting hole 12 has a locking function when the locking claw 15 is fitted and locked in the locking hole 32 portion formed in the projection portion. Is configured.

Reference numeral 33 denotes an attachment hole formed in the outer closing lid 3 for attaching to the handle 5 or the like of the slide fastener in the handbag.

The lock mechanism body 1 is configured by incorporating a known lock mechanism, and is configured such that the locking state of the lower locking lid 2 and the upper locking lid 3 can be released by operating the operation knob 13. ing.

Incidentally, these operation knobs 13 are provided with a safety structure in which the opening operation can be restricted by operating the lock mechanisms 14, 14 attached to the lock mechanism body 1.

The locking string 4 connected to the lower locking lid 2 is made thin by twisting a large number of fine metal wires such as a piano wire, but is not easily cut by a blade or the like.
It is made of a material capable of maintaining strong strength, and is constantly urged in the winding direction by a winding mechanism (not shown) attached inside the lock mechanism body 1.

In the key and lock industry, various lock mechanisms incorporated in the lock mechanism body 1 and lock mechanisms for preventing the locking projections 31 formed on the back surface of the closing lid from coming off are used in the key and lock industry. Since this is a well-known structure, detailed description thereof will be omitted.

In the figure, 6 is a bag and 7 is a net rack.

In the embodiment, the locking projections 21 and 31 formed on the rear surfaces of the two locking lids 2 and 3 are both locking mechanism main bodies 1.
Although described as being locked by a locking mechanism incorporated therein, it need not be limited to this mechanism.

That is, since the lower locking lid 2 is shielded from the outside by the upper locking lid 3, only the outer locking lid 3 which covers the lower locking lid 2 is required to have the locking function. For example, the locking projection 21 that is projected on the back surface of the lower locking lid 2 does not exhibit a locking function, and is simply fitted into the fitting hole 12 and then stopped. It is also possible to configure that only the locking projections 31 projectingly formed on the back surface of the abutting upper locking lid 3 are locked by the locking mechanism.
