Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snap button for use by a handicapped person or an elderly person.

[0002]

2. Description of the Related Art Generally, many snap buttons are very small, and as shown in a sectional view in FIG. 7, the engaging projections and the engaging holes of the male and female snap buttons are kept in a state of being superposed. Since it is necessary to press strongly with your finger,
It was difficult to use by handicapped persons and elderly people.

However, no snap button has been invented for such a handicapped person or an elderly person, and the person with a disability or the elderly person is prepared for difficult operability. In some cases, the snap button was used or the use of the snap button was avoided. Also,
In the case of a snap button having a slightly larger size, it is slightly better to grip, and therefore a snap button having such a large size may be used.

[0004]

However, the above-mentioned snap button having a large size is slightly better when gripped by fingers, and the edge portion of the engaging hole of the female snap button functions slightly as a guide portion. However, substantially, the male and female snap buttons must be exactly overlapped at the time of engagement.

Therefore, the large-diameter snap button does not facilitate the attachment / detachment operation, but is merely easy to grasp, and in the end, the male and female snap buttons are accurately overlapped and engaged. Requesting an operation for a handicapped person or the like has nothing to do with a normal snap button, and was very inconvenient for the person with the handicapped person and the elderly.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an excellent snap button that can be easily used by persons with disabilities or the elderly, who are handicapped. This is a problem to be solved by the invention.

[0007]

A snap button comprising a female snap button having an engaging hole at the center in plan view and a male snap button having an engaging protrusion fitted into the engaging hole, The female snap button is provided with a mortar-shaped recess formed on the periphery of the engagement hole, in which an inclined surface having a width larger than the width dimension of the engagement head of the engagement projection of the male snap button is formed. The button is a means for solving the problem.

[0008]

According to the present invention, since the mortar-shaped recess having a width equal to or larger than the width dimension of the engaging head of the engaging projection of the male snap button is formed on the peripheral edge of the female snap button, the engagement of the male and female snap buttons is achieved. Even if the engaging head of the engaging protrusion and the engaging hole do not overlap at all when engaging, the engaging head of the male snap button is simply snapped with the fingers. Since the button slides on the mortar-shaped recess and is guided to the engagement hole, precision is not required for the engagement head and the engagement hole to be superposed, so that the handicapped person or the elderly person may have difficulty. Even if there is, the snap button can be easily engaged.

Further, when the entire contact surface of the female snap button is formed into a mortar-shaped recess, no matter which position of the contact surface of the female snap button is pressed by the engaging projection of the male snap button, it is immediately possible. The male and female snap buttons can be engaged by being guided to the engaging hole.

Further, when the engaging projection of the male snap button combined with the female snap button is provided with a truncated cone-shaped protrusion reinforcing portion, the protrusion reinforcing portion has a female snap portion during the engaging operation. The button can be prevented from interfering with the mortar-shaped recess of the button, and the male engagement protrusion can be prevented from being broken by the load on the male engagement protrusion while being guided by the mortar-shaped recess. .

Further, a mortar-shaped recess of the female snap button,
The contact between the male snap button and the inclined surface of the protrusion reinforcement part prevents the male and female snap buttons from rotating relative to each other, thereby preventing the male and female snap buttons from being unintentionally disengaged, resulting in a stronger engagement state. Is supposed to be able to get.
