Description

TECHNICAL FIELD The present invention relates to a button that can be attached to fabrics such as clothes with one touch.

As shown in FIGS. 3A and 3B, as a conventional button that can be attached to cloth such as clothes with one touch, a button fastener 51 is passed through cloth 52 and button is fastened to a hole 54 in the center of button 53. There is one in which when the round shape 55 of the tool 51 is pushed in, it cannot be pulled out as it was before due to the catch 56 (Patent Document 1).

The above-described conventional button has the advantage that it is easier to attach than a button that is fastened with a thread and that it does not break like a thread and lasts a long time.

Japanese Utility Model Laid-Open No. 4-110507

However, in the above-described conventional button, the button 53 has a front and a back, and as shown in FIGS. The round shape 55 passing through fits in the recess 57, but if the button stopper 51 is accidentally pushed from the front side of the button 53 (the recess 57 side), the round shape 55 passing through the hole 54 protrudes outside the button 53 and is worn. There may be problems such as damage to the skin of a person or deterioration of the appearance.

In addition, there is a large resistance when pushing the round shape 55 into the hole 54, which may reduce the mounting workability and may cause the wrong side of the button 53 as described above.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a button that is less prone to erroneous mounting and that can improve mounting workability.

In order to achieve the above object, the button according to the present invention has a button body in which a cylindrical body having an axial length exceeding the maximum thickness of the head is continuously provided at the center of the back surface of a substantially flange-shaped head. and a leg part in which a rod-shaped body having an axial length exceeding the maximum thickness of the base is connected to the center of the back surface of a substantially flange-shaped base, and the button body is the tip of the cylindrical body. It has an insertion hole that extends from the center of the surface toward the head and does not reach the surface of the head. In the distal end surface of the cylindrical body, the opening peripheral edge portion of the insertion hole protrudes further toward the distal end side of the cylindrical body than the periphery of the opening peripheral edge portion (Claim 1). .

In the above button, the peripheral edge portion of the surface of the head is raised more than the central portion of the surface. A projecting portion may be formed extending across the through hole and having the appearance of a group of threads composed of a plurality of threads (Claim 2).

In the above button, the rod-shaped body has a pointed tip portion, an enlarged diameter portion that widens toward the base end side at a gentler degree than the sharp tip portion, and this A bulging portion that bulges radially outward of the rod-shaped body from the enlarged diameter portion, and the vertical cross-sectional shape of the outer peripheral surface of the bulging portion draws an outwardly convex curve, and a straight portion that has a smaller diameter than the bulging portion, in this order. The insertion hole may be provided with a constricted portion that can be engaged with the bulging portion and whose longitudinal cross-sectional shape of the inner peripheral surface draws an inwardly convex curve (Claim 3). ).

According to the invention of the present application, it is possible to obtain a button that is less likely to be attached incorrectly and that can improve the workability of attachment.

That is, in the button according to each claim of the present application, the button body is arranged on one side of the fabric and the leg part is arranged on the other side, and the rod-shaped body of the leg part is inserted into the insertion hole of the cylindrical body of the button body. The button (button body and leg parts) can be attached to the fabric with one touch without using tools. Therefore, for example, it is possible to attach the button of the present invention without tools (thread, needle, etc.) as an emergency measure when the button comes off.

Further, if the insertion hole extends to the surface of the head, the rod-shaped body can be inserted into the insertion hole from either the front end surface side of the cylindrical body or the head side, so there is a risk that the insertion direction will be incorrect. However, in the button of the invention of the present application, the insertion hole does not reach the surface of the head, so the above error does not occur.

Furthermore, when the rod-shaped body is inserted into the insertion hole, the peripheral edge of the opening constituting the entrance is thin and easily elastically deformed. .

In addition, by increasing the axial length of the cylindrical body and the rod-shaped body to some extent, it is possible to securely fit them together, and the axial length of the cylindrical body is increased to some extent. As a result, buttoning is facilitated in the same manner as the tuck button.

In the button according to claim 2, the central portion of the surface of the head is made thin, and a through hole is provided in the central portion of the surface to reduce the amount of material used, while the peripheral portion of the surface of the head is made thick, Moreover, the strength of the head can be improved by providing the protruding portion in the central portion of the surface. In addition, since the projecting portion having the appearance of a thread group (shape imitating a thread group) extends over the two through-holes, the two through-holes look like buttonholes. It is possible to give a realistic feeling as if the button is attached to the fabric, and to make it more difficult to make a mistake in the front and back of the button body when attaching the button to the fabric.

In the button according to claim 3, the sharpened portion, the enlarged diameter portion, and the bulging portion are provided in this order from the distal end side of the rod-shaped body toward the base end side, so that the rod-shaped body can be secured against the cloth and the cylindrical body. While reducing the resistance when inserting, the rod-shaped body can be firmly engaged with the cylindrical body, and it can be attached to relatively coarse fabrics such as knitted fabrics (the rod-shaped body is Since the threads that make up the fabric are not cut, they enter the gaps, and new holes are not made, so there is less risk of the button coming off from the fabric). It can also be attached to fine fabrics. In addition, since the bulging portion and the constricted portion are rounded and difficult to break, when the entire rod-shaped body is fitted into the cylindrical body and the bulged portion and the constricted portion are engaged, this engagement will provide resistance due to the fitting. Also, even if the rod-shaped body is slightly inclined with respect to the cylindrical body, the engaging force is unlikely to decrease because both the bulging portion and the constricted portion are rounded. There is an advantage that the engagement is easily maintained.

An embodiment of the present invention will be described below.

The button according to the present embodiment comprises a button body 3 (FIG. 1) in which a tubular body 2 having an axial length L2 exceeding the maximum thickness T1 of the head 1 is continuously provided at the center of the rear surface of a substantially flange-shaped head 1 (Fig. 1 (A) to (C)), and a leg part 6 in which a rod-shaped body 5 having an axial length L5 exceeding the maximum thickness T4 of the base 4 is connected to the center of the back surface of the substantially flange-shaped base 4. (See FIGS. 1(D) to 1(F)). As will be described later, the head 1 of this example has the greatest thickness at the peripheral portion, while the base 4 of this example is curved as a whole, but its thickness is substantially uniform throughout.

As shown in FIGS. 1B and 1C, the button body 3 extends from the center of the tip surface of the cylindrical body 2 toward the head 1 and has an insertion hole 7 that does not reach the surface of the head 1. When the rod-shaped body 5 is inserted into the insertion hole 7 from the distal end surface side of the tubular body 2, the rod-shaped body 5 is engaged with the insertion hole 7 as shown in FIG. As shown in FIGS. 1B and 1C, on the distal end surface of the cylindrical body 2, the opening peripheral edge 8 of the insertion hole 7 is formed around the opening peripheral edge 8. (It is conceivable that the amount of protrusion is 0.8 mm, for example). In FIG. 2(D), the outline of the button body 3 (insertion hole 7) partially overlaps the outline of the leg part 6 (rod-shaped body 5). There is no lap, and the insertion hole 7 is elastically deformed (deformed to expand its diameter) by the insertion of the rod-like body 5 .

In the button of this example constructed as described above, the button body 3 is arranged on one side of the fabric, and the leg part 6 is arranged on the other side. The button (the button body 3 and the leg part 6) can be attached to the fabric with one touch without using tools by inserting it into the hole 7 and fitting and engaging it. Therefore, for example, as an emergency measure when a button comes off, it is possible to attach the button of this example without tools (thread, needle, etc.).

Further, if the insertion hole 7 extends to the surface of the head 1, the rod-shaped body 5 can be inserted into the insertion hole 7 from either the tip surface side of the cylindrical body 2 or the head 1 side. However, in the button of this example, the insertion hole 7 does not reach the surface of the head 1 (as shown in FIG. 1A, the insertion hole 7 does not appear on the surface side of the head 1). , so the above error does not occur.

Furthermore, when the rod-shaped member 5 is inserted into the insertion hole 7, since the opening peripheral portion 8 forming the entrance thereof is thin and easily elastically deformed, the rod-shaped member 5 receives less resistance from the opening peripheral portion 8, and the insertion operation becomes easier. It becomes easier to proceed smoothly. Moreover, when the button is attached to the cloth, the opening peripheral portion 8 bites into the cloth to prevent rotation (the button exhibits a function of preventing rotation of the button about its axis with respect to the cloth).

In addition, by increasing the axial lengths L2 and L5 of the tubular body 2 and the rod-shaped body 5 to some extent, it is possible to firmly fit them together, and the axial length of the tubular body 2 is reduced. By increasing the length L5 in the direction to some extent, it becomes easier to fasten the button like the tuck button. Moreover, as shown in FIG. 1(C), the outer peripheral surface of the head 1 is tapered such that the diameter increases toward the surface of the head 1. By rounding the corners at the boundary between the outer peripheral surface and the back surface of the head 1, it is easy to remove the button after buttoning (when undressing).

On the other hand, in the button of this example, as shown in FIGS. 1A and 1C, the peripheral edge portion 1A of the surface of the head 1 is raised more than the central portion 1B of the surface, and the central portion 1B of the surface has the thickness of the head 1. A plurality of (four in the illustrated example) through holes 9 penetrating in a direction, and a projecting portion 10 extending over two through holes 9 of the plurality of through holes 9 and exhibiting the appearance of a thread group composed of a plurality of threads. is formed (integrally molded) (see also FIGS. 2(A) and (C)). The protruding portion 10 of this example has an appearance in which a group of threads made of a plurality of threads intersect in a cross shape, and the four ends of the protruding portion 10 are configured to have through holes 9 connected thereto.

In the button of this example constructed as described above, the surface central portion 1B of the head 1 is made thin, and the through hole 9 is provided in the surface central portion 1B to reduce the amount of material used, and the peripheral edge of the surface of the head 1 is reduced. The strength of the head 1 can be improved by increasing the thickness of the portion 1A and providing the projecting portion 10 in the central portion 1B of the surface. In addition, since the projecting portion 10 having the appearance of a thread (a shape imitating a thread) extends over the two through-holes 9, the two through-holes 9 look like button holes. It is possible to give a realistic feeling as if the button is attached to the fabric with a button attaching thread, and to make it more difficult to make a mistake in the front and back of the button body 3 when attaching the button to the fabric.

Furthermore, in the button of this example, as shown in FIG. A diameter-enlarging portion 12 that widens toward the proximal end side by a degree, and an expansion portion that bulges in the radially outer direction of the rod-shaped body 5 from the diameter-enlarging portion 12, and the longitudinal cross-sectional shape of the outer peripheral surface draws an outwardly convex curve. It has a projecting portion 13 and a straight portion 14 smaller in diameter than the projecting portion 13 in this order, and as shown in FIG. , a constricted portion 15 is provided in which the longitudinal cross-sectional shape of the inner peripheral surface draws an inwardly convex curve. Specifically, it is conceivable that the diameter of the bulging portion 13 is larger than the diameter of the straight portion 14 by 0.1 to 0.3 mm.

Further, in this example, the inner diameter of the portion of the insertion hole 7 excluding the constricted portion 15 is substantially the same as the outer diameter of the straight portion 14 of the rod-like body 5 and smaller than the maximum outer diameter of the bulging portion 13 . be. Therefore, when the rod-shaped body 5 is inserted into the insertion hole 7, the diameter of the insertion hole 7 is expanded due to elastic deformation when the bulging portion 13 passes through, and after the passage, the insertion hole 7 is elastically restored (reduced in diameter) to its original shape and expanded. It fits into the straight portion 14 following the portion 13 .

In the button of this example constructed as described above, the sharpened portion 11, the enlarged diameter portion 12, and the bulging portion 13 are provided in this order from the distal end side to the proximal end side of the rod-shaped body 5, thereby forming a material and a cylindrical shape. While reducing the resistance when inserting the rod-shaped body 5 into the body 2 (insertion hole 7), the fitting engagement of the rod-shaped body 5 with the cylindrical body 2 can be performed firmly, and the knitted fabric is relatively smooth. It is also possible to attach the button to coarse fabric (the rod 5 enters the gap without cutting the threads that make up the fabric, and does not make new holes, so the risk of the button coming off from the fabric is reduced. ) On the other hand, since the rod-like body 5 is tapered by the pointed portion 11, it can be attached to relatively fine cloth. Further, since the bulging portion 13 and the constricted portion 15 are rounded and not easily damaged, when the rod-like body 5 is entirely fitted into the cylindrical body 2 and the bulging portion 13 and the constricted portion 15 are engaged, this can be achieved. The engagement is difficult to be released due to the resistance caused by the fitting, and even if the rod-like body 5 is slightly inclined with respect to the cylindrical body 2, both the bulging portion 13 and the constricted portion 15 are rounded, so that There is an advantage that the engagement force is unlikely to be reduced, and therefore the engagement between the two can be easily maintained.

As shown in FIG. 2(B), when the rod-shaped body 5 is engaged with the cylindrical body 2 , the movement of the rod-shaped body 5 further into the cylindrical body 2 is the base of the leg part 6 . 4, the edge 8 of the opening of the button body 3 comes into contact with the fabric (not shown). 10) is pressed and crushed. The position where the sharpened portion 11 is pressed is the innermost wall of the insertion hole 7 and the back side of the protruding portion 10 near the center portion, and the protruding portion 10 is not flat but has an appearance of a group of threads composed of a plurality of threads. , and because of its high strength, there is an advantage that it is less likely to be damaged or deformed by pressing of the sharpened portion 11 . In addition, as the pointed portion 11 is crushed, the entire portion of the rod-shaped body 5 that has passed over the constricted portion 15 is deformed in the direction along the inner wall of the insertion hole 7, and the engagement between the bulging portion 13 and the constricted portion 15 is broken. It can also be expected to become stronger. However, the depth of the insertion hole 7 or the axial length L5 of the rod-like body 5 may be appropriately set so that the sharpened portion 11 is not crushed.

As materials for the button (button body 3, leg part 6) having the above configuration, for example, synthetic resin such as polyacetal resin (POM), nylon resin (PA), acrylic resin, polyethylene terephthalate resin (PET) may be used. can be considered.

It goes without saying that the present invention is not limited to the above-described embodiments, and can be modified in various ways without departing from the gist of the invention. For example, the following modifications can be given.

In the example of FIG. 1(A), four through-holes 9 and a cross-shaped projecting portion 10 are provided so as to present a form in which a thread is threaded through a four-hole button, but the present invention is not limited to this. The four-hole button may have a form in which the thread is threaded by a method other than the cloth, or the number of through-holes 9 may be two so as to present a two-hole button.

In the example of FIG. 1(C), the insertion hole 7 reaches a position corresponding to the inside of the head 1, but the present invention is not limited to this. may be configured.

In addition, it cannot be overemphasized that you may combine suitably the modification mentioned in this specification.
