Description

The present invention relates to, for example, a technique that enables a snap fastener (dot fastener for clothing) composed of male and female snap buttons to be elastically fitted to a cloth such as clothing without using a special tool.

Snap fasteners that can be attached to fabrics such as clothes without using special tools are known (for example, Utility Model Registration Document 1), and the holding member 51 shown in FIG. 7 (A) and the female shown in FIG. 7 (C). The mold fitting member 60 and the male fitting member 70 shown in FIG. 7D constitute such a snap fastener. That is, the concave portion 61 of the female fitting member 60 shown in FIG. 7C and the convex portion 71 of the male fitting member 70 shown in FIG. 7D can be elastically fitted to each other. The holding member 51 makes it possible to hold the male and female fitting members 60 and 70 at predetermined positions of the cloth C, respectively, and a special tool such as a hitting tool is not required to hold the cloth C. A set of snap fasteners requires two holding members 51 and one fitting member 60, 70, respectively.

More specifically, as shown in FIG. 7A, the holding member 51 has a disk-shaped main body 52 and a shaft body 53 projecting from the center of the main body 52, and has an outer periphery of the tip end portion of the shaft body 53. A bulging portion 54 projecting outward is formed at two locations separated by 180 degrees, and a slit 55 is cut between the two bulging portions 54 from the tip surface of the shaft body 53.

On the other hand, as shown in FIG. 7C, the female fitting member 60 has a through hole 62 at the bottom of the recess 61, and is a substantially cylindrical shape of the male fitting member 70 shown in FIG. 7D. A similar through hole (not shown) is also provided on the bottom of the convex portion 71.

Then, in order to hold the female fitting member 60 by the holding member 51, the shaft body 53 of the holding member 51 is passed through a hole H (see FIG. 7A) provided in the cloth C of clothes or the like. As shown in FIG. 7 (B), after the main body 52 is positioned on the lower surface side of the fabric C and the shaft body 53 is projected toward the upper surface side of the fabric C, as shown in FIG. 7 (C). In addition, the female fitting member 60 may be brought close to the shaft body 53 of the holding member 51 from the upper surface side of the fabric C, and the shaft body 53 may be inserted straight into the through hole 62 of the fitting member 60 from below. .. When this insertion is performed, the two bulging portions 54 at the tip of the shaft body 53 are reduced in diameter by the slit 55 and then returned to the diameter, so that each bulging portion 54 passes through the through hole 62 and then the through hole 62. The fitting member 60 is held at a predetermined position (position of the hole H) of the fabric C by the holding member 51. The male fitting member 70 can be held by the holding member 51 in the same manner.

In the conventional snap fastener, the diameter of the expansion portion 54 can be reduced by the slit 55, so that the expansion portion 54 whose diameter is restored after passing through the through hole 62 is firmly locked to the opening edge of the through hole 62. However, in order to prevent the shaft body 53 from coming out of the through hole 62, it is necessary to increase the enlarged diameter portion 54 to some extent in both the radial direction and the axial direction of the shaft body 53. However, when the bulging portion 54 is enlarged, the concave portions 61 and the convex portions 71 of the male and female fitting members 60 and 70 that receive the bulging portion 54 must also be enlarged, and the male and female fitting members 60 and 70 are large. The problem arises that when the ends of clothes or the like provided with these are closed, the gap becomes large at that location.

Further, in the above-mentioned conventional snap fastener, since the slit 55 is deeply inserted, the strength of the shaft body 53 including the bulging portion 54 may decrease, and when the slit 55 is made shallow, the bulging portion 54 is made into the through hole 62. It will take a lot of power to pass it through.

Further, in the conventional snap fastener, in order to hold the female fitting member 60 by the holding member 51, the shaft of the holding member 51 is held from below the through hole 62 of the female fitting member 60. It is necessary to insert the body 53 straight, but since the tip side of the shaft body 53 is split in half by the slit 55, a female with respect to the shaft body 53 may be inserted depending on the axial orientation of the shaft body 53 at the time of insertion. There is also a problem that the fitting member 60 of the mold is easily tilted and it takes time to insert the mold.

The present invention has been made in consideration of the above-mentioned matters, and the purpose of the present invention is to reduce the size of the male and female fitting members, improve the strength of the holding member, and improve the workability of attaching the snap fastener to the fabric. It is an object of the present invention to provide a holding member which can be used and a snap fastener using the holding member.

In order to achieve the above object, the holding member according to the present invention is a holding member for holding a female or male fitting member constituting a snap button at a predetermined position on a cloth such as clothes. A main body having a shape or size that cannot be inserted into the through hole formed in the fitting member, and a main body that protrudes from the main body and is inserted into the through hole from one end side of the through hole and from the other end side. It has a substantially columnar shaft body through which a part of the shaft body is exposed, and the front side region of the shaft body has a substantially tubular shape, and the tip portion of the front side region is divided into three in the circumferential direction. On the outer peripheral surface of the shaft body, a locking projection that can be locked to the opening edge on the other end side of the through hole is provided (claim 1).

In the holding member, the locking projections are ridges extending in the circumferential direction on the outer peripheral surface of the shaft body, and a plurality of the locking protrusions may be provided at intervals in the axial direction of the shaft body (claim 2). ).

On the other hand, in order to achieve the above object, in the snap fastener according to the present invention, the female or male snap button constituting the snap fastener is the holding member according to claim 1 or 2, and the holding member. A female or male fitting member that is held in a predetermined position on a cloth such as clothes is provided (claim 3).

According to the present invention, a holding member capable of downsizing the male and female fitting members, improving the strength of the holding member, and improving the workability of attaching the snap fastener to the fabric, and a snap fastener using the holding member can be obtained.

That is, in the holding member of the invention according to each claim of the present application, the shaft body is inserted into the through hole of the fitting member by forming the front side region into a substantially cylindrical shape without providing a slit in the front side region of the shaft body. The deformability (degree of diameter reduction) of the shaft body can be suppressed to a small size, and accordingly, the locking projection for locking to the opening edge of the through hole can be made small, and the shape is substantially cylindrical without providing a slit. Since the front side region itself can be miniaturized due to its structure (without any problem in terms of strength), the front side region of the shaft body and the fitting member that receives the locking projection can be miniaturized.

Further, in the holding member of the present invention, the strength can be improved by forming a substantially cylindrical shape without providing a slit in the front side region of the shaft body.

Further, in the holding member of the present invention, the tip portion of the front region of the shaft body is divided into three in the circumferential direction, so that the shaft body is relative to the shaft body regardless of the axial orientation of the shaft body at the time of insertion. The fitting member is less likely to tilt, and the insertion work can be facilitated. Further, if the tip portion of the front region of the shaft body is divided into four or more in the circumferential direction, the strength tends to decrease, but if the tip portion is divided into three, the decrease in strength can be prevented.

In the holding member of the invention according to claim 2, by providing a plurality of locking projections at intervals in the axial direction of the shaft body, it is possible to cope with variations in the thickness of the fabric to which the snap fastener is attached. can.

It is explanatory drawing which shows the holding method of a member and a male fitting member.

Embodiments of the present invention will be described below.

The holding member 1 shown in FIGS. 1 and 2, the female fitting member 2 shown in FIG. 3, and the male fitting member 3 shown in FIG. 4 are attached to a cloth such as clothes without using a dedicated tool. It constitutes a possible snap fastener, and corresponds to the holding member 51 and the fitting members 60 and 70 shown in FIG. 7, respectively. That is, the set of snap fasteners of this example includes a female snap button composed of one holding member 1 and a female fitting member 2, and another holding member 1 and a male fitting member. It consists of a male snap button consisting of three.

Then, as described above, the holding member 51 constituting the conventional snap fastener forms the fitting members 60 and 70 at a predetermined position of the cloth C such as clothes (there is a hole H formed by an appropriate tool such as perforation). The holding member 1 places the fitting members 2 and 3 constituting the snap button at predetermined positions of the cloth such as clothes, as in the case of holding the snap button (see FIG. 7A). It is for holding.

As shown in FIGS. 1 and 2, the holding member 1 has a substantially disk-shaped main body 4 and a shaft body 5 projecting from the central portion on one surface side (upper surface side) of the main body 4.

The main body 4 has a through hole 6 formed in the female fitting member 2 (see FIGS. 3A to 3D) and a through hole 7 formed in the male fitting member 3 (FIG. 4B). )-(D)), it has a shape or size that cannot be inserted. Further, around the shaft body 5 on one surface side (upper surface side) of the main body 4, a plurality of spike-shaped small protrusions 8 that bite into the fabric C and prevent the main body 4 from rotating around the axis are formed at equal intervals in the circumferential direction. Has been done. The small protrusion 8 may have an appropriate shape capable of exerting this rotation prevention function. For example, the small protrusion 8 may have a substantially cylindrical shape as shown in FIG. 1 (A), or may have a substantially cylindrical shape as shown in FIG. 2 (A). As shown in (B), the tip of the cylinder may be sharpened to form a cone.

The shaft body 5 is a substantially circular circle that can be inserted into the through holes 6 and 7 of the male and female fitting members 2 and 3 from one end side of the through holes 6 and 7 and a part thereof is exposed from the other end side. It has a columnar shape. Then, the recessed portion extending from the center of the tip surface of the front side region 9 (shaft body 5) toward the base end side so that the front side region 9 (see FIG. 2B) of the shaft body 5 has a substantially cylindrical shape. 9a is formed. It is conceivable that the front side region 9 (recessed portion 9a) has a length of about 1/4 to 1/2 of the total length of the shaft body 3.

Further, the tip portion of the front side region 9 is divided into three in the circumferential direction to have three protruding portions 10, and the outer peripheral surface of the shaft body 5 has the other end side of the through holes 6 and 7. A locking projection 11 that can be locked is provided on the opening edge (upper end side). Here, the locking projections 11 are ridges (annular projections) extending in the circumferential direction on the outer peripheral surface of the shaft body 5, and a plurality of locking projections 11 (five in total in the illustrated example) are provided at intervals in the axial direction of the shaft body 5. There is.

On the other hand, the concave portion 12 of the female fitting member 2 shown in FIG. 3 and the convex portion 13 of the male fitting member 3 shown in FIG. 4 can be elastically fitted to each other, and may be elastically fitted to the bottom of the concave portion 12. The other end (upper end) of the through hole 6 faces, and the other end (upper end) of the through hole 7 faces the bottom of the convex portion 13.

The method of holding the male and female fitting members 2 and 3 by the holding member 1 is to hold the male and female fitting members 60 and 70 by the holding member 51 constituting the conventional snap fastener shown in FIG. It can be done in the same way as the method of making it, and the explanation is omitted in order to avoid duplication.

In the snap fastener of this example configured as described above, it is possible to reduce the size of the male and female fitting members 2 and 3, improve the strength of the holding member 1, and improve the workability of attaching the snap fastener to the fabric C. ..

That is, in the holding member 1 of this example, the front side region 9 of the shaft body 5 is not provided with a slit and the front side region 9 is formed into a substantially cylindrical shape, so that the through holes 6 and 6 of the male and female fitting members 2 and 3 are formed. The deformability (degree of diameter reduction) of the shaft body 5 when the shaft body 5 is inserted into the shaft body 5 can be suppressed to be small, and accordingly, the locking projection 11 to be locked to the opening edges of the through holes 6 and 7 is also small. In addition, the front side region 9 itself, which is substantially tubular without providing a slit, can be miniaturized due to its structure (without any problem in terms of strength), so that the front side region 9 of the shaft body 5 and the locking It is possible to reduce the size of the fitting members 2 and 3 having the recess 12 and the protrusion 13 for receiving the protrusion 11. For example, in the conventional snap fastener shown in FIG. 7, it is considered that the outer diameter of the bulging portion 53 in the natural state needs to be 0.5 mm or more larger than the inner diameter of the through hole 62. The outer diameter of 11 can be made larger by about 0.1 mm than the inner diameter of the through holes 6 and 7.

Further, in the holding member 1 of this example, the strength can be improved by forming a substantially cylindrical shape without providing a slit in the front side region 9 of the shaft body 5.

Further, in the holding member 1 of this example, since the tip portion of the front side region 9 of the shaft body 5 is divided into three in the circumferential direction, the shaft body 5 is inserted regardless of the axial orientation of the shaft body 5. The fitting members 2 and 3 with respect to the shaft body 5 are less likely to tilt, and the insertion work can be facilitated. Further, if the tip portion of the front side region 9 of the shaft body 5 is divided into four or more in the circumferential direction, the strength tends to decrease, but by dividing the tip portion into thirty, the decrease in strength can be prevented.

Further, in the holding member 1 of this example, by providing a plurality of locking projections 11 at intervals in the axial direction of the shaft body 5, it is possible to cope with variations in the thickness of the fabric C to which the snap fastener is attached. can do.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be variously modified and implemented without departing from the gist of the present invention. For example, the following modification examples can be given.

1 (A) and 2 (B) show an example in which a total of five locking projections 11 are provided on the outer peripheral surface of the shaft body 5, but the number of locking projections 11 is not limited to this. The number may be four or less, or six or more. For example, as shown in FIGS. 5A and 5B, only one locking projection 11 may be provided on the outer peripheral surface of the front region 9.

Further, as shown in FIG. 6, the locking projection 11 may extend spirally on the outer peripheral surface of the shaft body 5.
