Description

  The present invention relates to a button that can be sewn to a shirt, blouse, underwear, or other garment with a thread.

2. Description of the Related Art Conventionally, a button that has a plurality of threading holes formed in the center portion of a button body and is threaded through the threading holes and attached to clothes by sewing is well known. Such a button has a problem that the back of the button body is in close contact with the surface of the cloth of the clothes, so that it is difficult for an infant or an elderly person to put it on the button hole.
In consideration of the above problems, Patent Document 1 states that “a base plate portion, a leg portion standing on the base plate portion and passing through a button hole of clothes, and a tip of the leg portion. The button body is composed of the head part that is provided and latched on the button hole of the clothes, and the base plate part is configured to be fixed in a state of being in contact with the surface of the cloth of the clothes. A button characterized by "." (Claims).
However, the button described in the above-mentioned Patent Document 1 has a restriction on the usage method of fixing the base plate part to the surface of the cloth of the clothes, so that it is not always easy to attach to the clothes, The design cost of providing the base plate portion is accompanied, and the volume of the button is large, so that the material cost increases.
Patent Document 2 states that, “It has an elliptical outline in a plan view, a plurality of threading holes are formed in the center, and the inclined surface protrudes upward from the horizontal plane at least at both ends in the long axis direction. “A button for clothing that is formed so that the thickness of the front surface and the back surface is gradually reduced.” (Claims)
However, since the button described in Patent Document 2 has a plane shape and a cross-sectional shape of the button specified, it inevitably involves design restrictions.
Further, in Patent Document 3, “a threading hole is provided in the button body, and a short annular protrusion or an alternative button attaching thread protecting part is enclosed so as to surround the opening on the back side of the hole. Formed button ”(claims).
The button described in Patent Document 3 has an effect that the button mounting thread located inside the annular protrusion can be protected by the annular protrusion, and the annular protrusion is outside the attachment thread. For this reason, when using buttons with the same outer diameter as a reference, there are fewer parts to pick up the button when detaching the button than with a normal button. is there.
In addition, as described in Patent Document 4, a button is known in which a leg portion (shaft portion 5) is provided on the back side of the button body so that the leg portion is fixed to clothes. Because it has a complicated structure in which a fastener (rivet, etc.) is attached to the garment and the legs are connected to the garment, it is not easy to attach to the garment and is suitable for buttons such as jeans, but it is used for shirts, etc. It is not suitable for a relatively small diameter button.

  The present invention solves the problems described in the background art, and provides a button that can be easily attached to clothes, easily detached from a button hole, and is not subject to design restrictions. This is the issue.

(1) A button provided with a plurality of threading holes formed in the button body, and sewn to a garment with a thread that has passed through the plurality of threading holes, avoiding the threading holes, A protrusion is formed on the back surface of the button body, which is a substantially central region between the threading holes ,
The outermost edge portion of the projecting portion is located inside a virtual circle circumscribing the plurality of threading holes, and is located outside a virtual circle inscribed in the plurality of threading holes,
The projecting portion lacks a virtual cylindrical shape body located in the middle of a virtual circle circumscribing the plurality of threading holes and a virtual circle inscribed in the plurality of threading holes in a portion corresponding to the threading holes. Form,
An end of the protruding portion that contacts the clothes is a button that is formed in a flat shape .
(2) The protruding portion is a button formed so as to have an almost X shape when viewed from the back side of the button body.

(1) According to the present invention, the button can be attached to the garment by a simple method of sewing the button to the garment with the thread passed through the threading hole formed in the button body, and the button is garmented with the thread. Since the protrusion formed on the back of the button body comes into contact with the cloth of the garment when sewing, the button is attached to the garment with a gap between the back of the button body excluding the protrusion and the cloth. It will be. For this reason, when the button is hanged, it is easy to put a finger between the button and the cloth, and the button can be easily picked by the finger, and the button hole is easy to hang.
Further, since the protrusion is formed on the back surface of the button main body, which is a substantially central region between the plurality of threading holes, there is no design restriction such as the surface shape of the button main body.
Further, since the protrusion is formed on the back surface of the button main body, which is a substantially central region between the plurality of threading holes, the protrusion is overlapped around the thread for attaching the button through the plurality of threading holes. It is also possible to adopt a strong attachment method for winding the yarn. With the button described in Patent Document 3, such a mounting method cannot be adopted.
( 2 ) The protrusion is configured so as to have a substantially X shape when viewed from the back side of the button body, so that the protrusion abuts against the cloth of the clothes in a stable state, and the button is securely attached to the clothes. Can be attached to.

(A) is a top view of the button 1, (b) is a front view, (c) is a cc cross-sectional view of (a), and (d) is a rear view. It is explanatory drawing of the protrusion part 20 seen from the back side of the button 1. FIG. It is sectional drawing which shows the state which attached the button 1 to clothes. FIG. 10 is an explanatory diagram of an example of using the button 1.

In a button provided with a plurality of threading holes formed in the button body, and sewn on clothing with threads threaded through the plurality of threading holes, avoiding the threading holes and between the threading holes. A protrusion was formed on the back surface of the button body, which is a substantially central region.
Hereinafter, embodiments will be described with reference to the drawings.

The button 1 includes a disk-shaped button body 10 and a protrusion 20 formed on the back surface of the button body 10. The button main body 10 and the protruding portion 20 are preferably formed integrally, but those formed separately may be integrated by means such as adhesion.
The planar shape of the button 1 is not limited to a circle, and may be an ellipse, a polygon, or the like.
As a material of the button 1, a synthetic resin is generally used, but natural materials such as metal, glass, wood and shells, and other appropriate materials can be used.

A plurality of threading holes 11 penetrating the front and back surfaces of the button body 10 are formed in the center of the button body 10. In this embodiment, four threading holes 11 are provided. The plurality of threading holes 11 are usually provided in the center of the button body 10, but may be eccentric with respect to the planar shape of the button body 10. The number of the button through holes 11 is usually 2 or 4, but may be an odd number such as 3, 5 or the like.
On the outer peripheral portion of the surface of the button main body 10, a stepped portion 12 is provided that protrudes toward the surface side of the portion where the button through hole 11 is provided. This is to make it easier to pick the button 1 and is a known mode.

On the back surface of the button body 10, a protruding portion 20 is formed in a substantially central region between the plurality of threading holes 11, 11, 11, 11, avoiding the threading hole 11.
In addition, a tapered portion 13 is formed so that the thickness of the button body 10 decreases from the vicinity of the portion where the threading hole 11 is provided toward the outer periphery. The tapered portion 13 makes it easier to insert a finger between the button body 10 and the fabric.
In a button having an even number of threading holes 11, the protrusion 20 is preferably formed so as to be located over at least a region connecting the threading holes 11 and 11 that are in an opposing positional relationship. .
The height H1 of the protrusion 20 is desirably in the range of 0.8 to 1.4 with respect to the thickness H2 of the portion of the button body 10 where the threading hole 11 is provided.

As shown in FIG. 2, it is desirable that the outermost edge portion 21, which is the maximum outer diameter of the protruding portion 20, be formed so as to be located inside the virtual circle C <b> 1 circumscribing the plurality of threading holes 11. Moreover, it is desirable to form so that it may be located outside the virtual circle C2 inscribed in the plurality of threading holes 11.
In this embodiment, the outermost edge 21 of the protrusion 20 is formed at an intermediate position between a virtual circle C1 circumscribing the plurality of threading holes 11 and a virtual circle C2 inscribed in the plurality of threading holes 11. . Further, since the protruding portion 20 is lacking in the threading hole 11 portion, the protruding portion 20 is formed so as to have a substantially X shape when viewed from the back side of the button body 10.
In the present embodiment, the projecting portion 20 is formed solid, but it may be hollow or a cylindrical shape formed by leaving only the outer edge portion (contour portion) in plan view.

FIG. 3 shows a state in which the button 1 is attached to clothes. Reference numeral 30 denotes a cloth of clothes. Reference numeral 40 schematically shows a thread for sewing.
The thread 1 for sewing is threaded through a plurality of threading holes 11 formed in the button main body 10 with the tip of the projecting portion 20 in contact with the fabric, and the button 1 is sewn on the fabric 30.
Since the protrusion 20 formed on the back surface of the button body 10 contacts the cloth 30 of the clothes, the height H1 of the protrusion 20 corresponds to the distance between the back surface of the button body 10 and the cloth 30 except for the protrusion 20. A gap is created. Therefore, when the button 1 is unloaded, it is easy to put a finger between the button 1 and the fabric 30, and the button 1 can be easily picked with the finger, so that the button hole is easily unloaded.
As shown in FIG. 4, when one end of the button body 10 is pushed toward the cloth 30, the cloth 30 has flexibility, so that the other end of the button body 10 is on the cloth 30 with the protrusion 20 as a fulcrum. And the button 1 is more easily separated from each other.
