<Function and operation method>
Next, based on FIG.5 and FIG.6, the function and operation method of a snap fastener with a locking mechanism are demonstrated.

FIG. 5 shows the unlocked state of the male and

female members

2 and 3. From this state, as shown by the arrow (b), when the pressing piece 42 of the operation plate 4 is pressed down with a finger, the pressing protrusion 44 enlarges the tip clearance 54 of the inner arc 53 of the spring 5. Then, the engagement protrusion 8 of the male member 3 can be inserted, and the engagement of the male and

female members

2 and 3 is completed. FIG. 6 shows the locked state of the male and female members. When the finger is released from the pressing piece 42 of the operation plate 4 and stopped to be pressed down, the tip clearance 54 of the inner arc 53 of the spring is restored and narrowed, and the male member 3 is engaged with the tip bulging portion 83 being prevented from coming off. Is maintained.

It is not sufficient to simply depress the pressing piece 42 to release the male and

female members

2 and 3 from this engaged state. This is because the spring 5 is restored as soon as the finger is released from the pressing piece 42. Therefore, in order to separate the male and

female members

2 and 3, it is necessary to lift the turning piece P1 while pressing the pressing piece 42 down. If the normal person does not know that the pressing piece 42 is pushed down and the turning piece P1 is lifted up at the same time, trial and error must be repeated. It is extremely difficult for dementia patients.

The present invention can be modified and changed in various ways within the scope of the claims.

For example, as shown in FIGS. 13 and 14, the turning piece P1 can be appropriately reinforced with a hard plate 11 or packing. Then, when the operation of pulling up the female member 2 while holding down the pressing piece 42 of the female member 2 for opening, it becomes impossible to be conscious of it more clearly, and there is a possibility that it will come off by an unexpected operation of a dementia patient. Lower. *

Further, as shown in FIG. 15, for example, an extension 68 can be provided at the tip of the main body 61A of the base 6A. The extension portion 68 is the second cylinder in the illustrated example, but is not limited to the cylinder, and may be a continuous or intermittent convex bank, and is configured to be in contact with the engagement protrusion 8 at at least three points. To do. By doing so, when the male and female members are combined, as shown in FIG. 16, there is no play in the engaging protrusion 8, and the connection is more reliable. If there is play in the engaging protrusion 8, an unexpected force is applied due to the patient's intense movement, etc., and the male and female members may come off.

Further, although not shown, with respect to the male member, a packing such as an egg-shaped synthetic leather can be sandwiched immediately below the female member. If it does so, it will become easy to perform the operation | movement which turns while pressing the pressing piece 42 of a female member, and releasing operation | movement will become easy. As a result, usability is improved while securing the anti-theft function from snatching and the like when used for, for example, bags other than nursing care applications.
