Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a snap button as an accessory for clothes. 2. Description of the Related Art As is well known, a snap button is composed of a pair of male snaps and female snaps. By attaching and detaching to and from the engaged portion (fitting hole), the button is attached and detached, that is, fastened (ON) and removed (OFF). The attachment and detachment of the engaging portion and the engaged portion are performed from these axial directions, as is well known. [0003] In the above conventional snap button, the ON action generally requires a slightly stronger force than the OFF action, and the OFF action often requires both hands. In some cases, the cared person or the like cannot smoothly perform such ON and / or OFF actions. Therefore, an object of the present invention is to provide a snap button that can be easily attached and detached even by a person who has difficulty attaching and detaching a conventional product. According to the present invention, a male snap having a convex engaging portion and a female snap having a concave engaged portion are provided. In the snap button that is detachable from the engaged portion in the axial direction, an engaging portion guide groove that allows the engaging portion to be detachable from the engaged portion in the radial direction is connected to the engaged portion. A snap button is provided, wherein the snap button is provided. That is, in the snap button according to the present invention,
The engaging portion of the male snap and the engaged portion of the female snap can be attached and detached from these axial directions in the same manner as the conventional product. By moving along the engaging portion guide groove communicating with the engaging portion, the attaching and detaching of the engaging portion and the engaged portion can also be performed from these radial directions. As the material of the male snap and the female snap, plastic or the like can be preferably used so that the engaging part and / or the engaged part is slightly elastically deformed at the time of attachment and detachment. In order to make such elastic deformation more effective, for example, a plurality of slits can be provided in the engagement portion. Hereinafter, preferred embodiments of a snap button according to the present invention will be described with reference to the accompanying drawings. 1 and 2 are a plan view and a perspective view of the male snap 10, and FIGS. 3 and 4 are a plan view and a perspective view of the female snap 20, respectively. [0008] Male snap 10 and female snap 2
0 is a plastic snap and 10 male snaps
Includes a substantially disk-shaped base 11 and a substantially cylindrical engaging portion 12 projecting upward (in FIG. 2) (back side of the base 11) from the base 11. The male snap 10 is
Generally, the lower side of the garment is integrally stopped by a cap member (not shown) across the lower front so as to come to the front side. At the top of the engaging portion 12, an enlarged diameter portion 13 is formed which slightly expands radially outward. The enlarged diameter portion 13 is provided with slits 14 at three positions at intervals of 120 degrees. Each slot 14 allows for a slight elastic contraction of the enlarged diameter section 13 (and its restoration). The number of the slits 14 is not limited to three, but may be two, four, or the like. Even if the slit 14 is not provided, the plastic engaging portion 12 may exhibit required elasticity. Can be. The female snap 20 is a male snap 1
A substantially disk-shaped base 21 having substantially the same thickness as the total thickness of the base 0 (the height of the base 11 + the engaging portion 12) is provided with a concave portion 22 as described below. That is, the concave portion 22 is connected to the engaging portion 12 of the male snap 10 to be engaged with the engaging portion 12 to define the fastening state of the button. Engaging portion guide groove 2 which is provided and opens to one side of the base 21.
4 The C-shaped side portion 23 'forming the fitting hole 23 is
The lower half (in FIG. 4) is larger in diameter than the upper half. More specifically, the upper half of the side portion 23 ′ slightly exceeds the outer diameter of the engaging portion 12 except for the enlarged portion 13 of the male snap 10, and the lower half has the outer diameter of the enlarged portion 13. Slightly above. Further, the width of the engagement portion guide groove 24 is slightly larger than the enlarged diameter portion 13 of the engagement portion 12. Further, at the upper half (in FIG. 4) of the boundary between the fitting hole 23 and the engaging portion guide groove 24, two engaging portion locking portions 25 slightly projecting inward in the radial direction are provided. ing.
The interval between the engaging portions 25 is slightly smaller than the outer diameter of the engaging portion 12 excluding the enlarged portion 13 of the male snap 10. The female snap 20 is generally
Contrary to the male snap 10, the upper side is integrally stopped by a cap member (not shown) from the front side so as to come to the back side of the upper side of the cloth. Next, the operation of attaching and detaching the snap button will be described. When the engaging portion 12 of the male snap 10 is mounted in the fitting hole 23 of the female snap 20 in the axial direction A (see FIG. 5), the enlarged diameter portion 13 of the engaging portion 12 is slotted. 14 is slightly elastically reduced in diameter and fitted into the fitting hole 23, and is restored (expanded in diameter) upon completion of the fitting. As a result, the engaging portion 12 exactly fits the side portion 23 ′ of the fitting hole 23 and is restrained in the axial direction A in the fitting hole 23. The engagement portion 12 in this state is also prevented from moving toward the engagement portion guide groove 24 by the engagement portion locking portion 25, and is moved in the radial direction R (FIG. 6).
(See the arrows immediately before / after attachment / detachment.) When the engaging portion 12 is mounted in the fitting hole 23 from the radial direction R, the male snap 10 is moved horizontally so that the engaging portion 12 is along the engaging portion guide groove 24. Engagement part 12
While moving toward the fitting hole 23, the engaging portion locking portion 25 comes into contact with the engaging portion 12 and resists the movement of the engaging portion 12. Part locking part 2
5 can be elastically expanded, and the engaging portion 12 can be fitted into the fitting hole 23. The engaging portion 12 in this state is fitted in the fitting hole 23 in exactly the same manner as when the device is mounted in the axial direction described above. When the engaging portion 12 is detached from the fitting hole 23, it can be detached from the axial direction A in the same manner as in the prior art, or can be detached from the radial direction R as follows. That is, the engaging portion 1 in the fitted state
2 releases the engagement portion engagement portion 25 and engages the engagement portion guide groove 24.
The male snap 10 is horizontally moved relative to the female snap 20 so as to face the side. With the above snap button, for example, even if it is difficult to perform an ON action from the axial direction A or cannot perform an OFF action with both hands due to obstacles or other reasons, the ON action is performed from the radial direction R. ,
OFF action from the radial direction R with one hand is the axial direction A
The degree of freedom and ease of attachment / detachment can be significantly increased as compared with conventional products by adjusting the protrusion height of the engaging portion locking portion 25 so as to be easier than that of the conventional product. FIG. 7 shows a modified example of the female snap. The engaging portion guide groove 34 of the female snap has a groove width gradually increasing radially outward. Thereby, when the snap button is mounted from the radial direction R, the engaging portion 12 of the male snap 10 can be more easily inserted into the engaging portion guide groove 34. FIG. 8 shows a further modification of the female snap. The engagement portion guide groove 44 of the female snap has an inclined surface whose bottom surface is gradually lowered outward in the radial direction. This slope also contributes to enlarging the entrance of the engaging portion guide groove 44 and facilitating the receiving and engaging of the engaging portion 12 from the radial direction R. The female snap shown in FIG. 8 is also not provided with a notch indicated by reference numeral 26 in FIGS. The notch 26 is for partially expanding the diameter of the fitting hole 23 to finely adjust the amount of force required at the time of the ON action mainly from the axial direction A. When there is no notch 26 as shown in FIG. 8, the force at the time of the ON action is slightly weakened. The inclined surfaces of the notch 26 and the engaging portion guide groove 44 can be set independently. In the above embodiment, the male snap 10
And the female snap 20 are concentric when mounted, but the engaging portion 12 or the fitting hole 23 is slightly eccentric with respect to the center of the bases 11 and 21, and the male snap 10 and the female snap 20 are mounted. At times, it may be slightly eccentric. By displacing the fitting hole 23 from the center of the base 21, the engaging portion guide groove 24
Can be set longer, and the attaching / detaching operation from the radial direction R can be performed more reliably. As described above, in the snap button according to the present invention, the male snap and the female snap can be attached and detached not only in the axial direction but also in the radial direction. The degree of freedom and easiness are increased, and even a weak person such as a disabled person who could not hold and remove the product by himself with the conventional product can do this by himself.
