Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a button, and particularly relates to a button which requires a tool to release the engagement although the engagement is easy.

[Prior Art] Buttons are used in a wide range of fields of daily life, and snap-type buttons, buttonhole-type locking types, and the like are known. These buttons are easy to lock and relatively easy to release.

However, it turns out that using these buttons can be inconvenient. As an example, this corresponds to a button on clothes of a demented elderly person.

An elderly person with dementia often unbuttons the clothes he is wearing, and it often takes time for nursing. When it is necessary to devise to remove the button, for example, even if the surface plate of the button is made of an elastic plate and is released only when the surface plate is strongly pressed, it will take a long time to remove it. There was a problem.

In addition, buttons on seat covers for public vehicles such as buses and hire, buttons for closing small pockets such as bags and inner pockets for suitcases, etc. will be released by someone other than the person concerned or the action of external force. There may be a problem.

In order to solve the above various problems, the present inventors have developed a button as disclosed in Japanese Utility Model Laid-Open No. 63-52405.

The structure and function of this button will be briefly described with reference to FIGS. 15 to 19.

FIG. 15 illustrates a female member 71 and a mounting member 72 for mounting the female member 71 on cloth such as clothes. The female member 71 is annular,
A mounting portion 75 is formed whose peripheral edge is curved downward and then inward to receive and hold the claw of the mounting member. Further, a hole 77 having a predetermined size is formed in the center, and the locking portion of the male member is inserted through the hole 77, and the step portion 86 of the locking portion of the male member is engaged by the peripheral edge 76 of the hole 77. It is supposed to be stopped.

FIG. 16 illustrates the male member 73 and its mounting member 74. The male member 73 is composed of a disk-shaped base portion 80 and a columnar locking portion 81 which stands upright from the central portion thereof. A hole 82 for mounting is formed in the base portion 82, and the pin of the mounting member 74 is accommodated in this hole 82.
The columnar locking portion 81 has a root portion 85 smaller than the diameter of the hole 77 of the female member 71, a step portion 86 of a size that can be locked to the locking portion 86, a large diameter portion 87 larger than the diameter of the hole 77, And the tip consists of a conical taper portion 88 having a diameter smaller than the diameter of the hole 77, and a columnar locking portion 81.
A split groove 89 is deeply cut on the central axis line of the tape member 88, and when the locking portion 81 of the male member is inserted through the taper portion 88 into the hole 77 of the female member, the tape portion 88 elastically moves inward. You can bend.

The mounting member 74 is composed of an annular base 90 and a pin 91 which can be swaged upright from the base 90. The diameter of the pin 91 is slightly smaller than the diameter of the hole 82, and its tip is, as shown in FIG. 17,
The cloth for clothes is pierced, inserted into the hole 82 of the base 80 of the male member 73, and then crimped to fix the male member.

Next, the function of hooking the male member and the female member after being attached to the cloth will be described. When the tapered tip of the male member 73 is inserted into the hole of the female member 71, the tapered portion elastically bends inward, and when the step 86 exceeds the hole 77, the tapered portion 88 is restored and locked with the step portion 86. The portions 76 can be locked together in a detented state. Therefore, by appropriately selecting the size of the split groove 89 and the like, it is possible to provide a button with a strong hooking state that cannot be removed by a human finger. In order to remove the button that has been engaged in this way, as shown in FIG. 18, prepare a tool 94 having a tapered hole, and make the tapered hole in the direction of the arrow in the figure (that is, the direction perpendicular to the cloth). ) Toward the taper portion of the male member so that the diameter of the large diameter portion of the locking portion 81 of the male member becomes smaller than the diameter of the hole of the female member, and further push the tool 94 in the direction of the arrow. This releases the hook. Another example of the tool 94 is a pliers as shown in FIG.
95 is conceivable. The latch is released by sandwiching the peripheral portion of the button and using the elasticity of the handle of the pliers to press the tool 94 in the direction of the arrow in the figure.

However, the tool for unlocking as shown in FIG. 19 has a complicated structure and a large structure, which is inconvenient to carry, and for example, the above-mentioned bag or suit which must be carried by a person concerned. It was found to be inappropriate to apply to buttons with locks such as.

In addition, the above-mentioned button cannot be released from the hook unless the tool is pressed against the body of the button wearer such as a demented elderly person, and the body of the button wearer is strongly pressed locally. Depending on the tool used, it may cause discomfort, and even if the tool is pressed hard, the button may also move to the body side together with the tool, and the latch may not be released.
It turns out that there is a problem that it is difficult to release the hook.

Furthermore, since the locking portion 81 of the male member is upright vertically to the cloth, it is difficult to apply it to a vehicle interior seat cover, chair cover, duvet cover, etc., and it does not look good, for example, a bag or the like. It was also found to be unsuitable as a button with a lock for closing inner pockets such as purses and suits.

[Object of the Invention] Accordingly, an object of the present invention is to provide a button with a lock that can be reliably released from the hooked state by using a hook releasing tool that has a simple structure and is convenient to carry. Is.

Another object of the present invention is to provide a button with a lock that can release the hooked state without pressing the body of the button wearer without causing discomfort to the wearer.
