Description

[Detailed Description of the Invention] This invention relates to an improvement of a back hole button which is constructed so that the legs protruding from the back surface of the button body are attached to the clothing material with a sewing thread.

As shown in FIGS. 6 and 7, the conventional back hole button has a leg body 11 having a through hole 12 for attachment protruding from the back surface of the button body 10, and thread A is inserted through the through hole 12. It is designed to be sewn together. The button 1 attached in this manner will fall forward due to its own weight when the front clothing material (not shown) to which it is latched is unlatched, causing the head to droop. Furthermore, if the decorative buttons do not have the function of latching the seams of clothing, the head will always be held in a sagging position, resulting in a very poor appearance.

In order to prevent the above-mentioned head from drooping, the tip end surface 13 of the leg body 11 should be formed into a flat surface as shown by the imaginary line, and the flat end surface 13 should be sewn to the clothing material 2 in a state in which it is in close contact with the clothing material 2. is possible. but,
If the sewing thread A loosens during use, the head of the button will sag, and in order to minimize the amount of sagging of the button head, it is necessary to increase the distance in the width direction of the leg 11 as much as possible. For this reason, the legs 11 have to push the button holes of the front clothing wide open and pass through them, resulting in deformation and fraying at the ends of the button holes of the front clothing.

This idea was made in view of the above points, and by reducing the distance in the width direction of the legs when the button is attached, it is possible to prevent the end of the button hole from losing its shape or fraying. Moreover, the object is to obtain a back hole button that can be held stably without the head hanging down.

Embodiments of this invention will be described below with reference to the drawings. In FIGS. 1 and 2, the back hole button 3 is formed by integrally forming a button body 30 and a leg body 31,
The distal end surface 33 of the leg body 31 is formed as a flat surface, and the mounting through hole 32, which serves as a locking portion where the sewing thread is concentrated and locked, is located at a position eccentric to one side in the width direction of the leg body. It is formed.

The leg end surface 33 of the button 3 configured as described above
, the clothing fabric 2 is placed in such a state that the through-hole 32 for attachment is located upward, that is, at the upper side in the vertical direction in the attached state.
and sew with thread A. In this way, by making the through hole 32 eccentric so that it is located above the center in the width direction of the leg body when the button 3 is attached, it is possible to effectively prevent the head from drooping. At the same time, the width dimension of the leg body 31 can be kept small. In other words, it is the leg tip surface 3 that helps prevent the head of the button 3 from drooping.
This is the surface below the through hole 32 of No. 3, and this through hole 32
By making the lower surface of the button 3 as long as possible, that is, the lower part in the vertical direction when the button 3 is installed, it is possible to more effectively prevent the head of the button 3 from drooping, and also to make the surface above the through hole 32 as long as possible. By making it short, the overall width of the leg body 31 is reduced.

Therefore, even if the sewing thread A becomes loose due to use, the amount of sagging of the head of the button 3 will be minimal, and the button hole will not be pushed wide open when attaching the front clothing material. There is no risk of deformation or fraying at the end of the hole.

Next, another embodiment of this invention will be described.
In the back hole button 3a shown in FIG. 3A, the apex of a triangular through hole 32a formed in the leg body 31a is formed at a position eccentric to one side with respect to the widthwise center of the leg body 31a, and the apex is It is attached to the clothing fabric 2 by locking the sewing thread A at this apex while being positioned above the top. The back hole button 3b shown in FIG. 3B has a leg 31b made of a band-shaped metal wire or a synthetic resin material, and a recess 32b is formed on one side of the leg 31b in the width direction. A bulging portion 32b is provided from the center in the width direction of the tip of the leg to the other end, and the sewing thread A is attached by locking the sewing thread A in this recess 32b with the recess 32b positioned vertically upward. It is configured so that In addition, the above button 3 is shown in Fig. 3C and D.
Back hole buttons 3c and 3d are shown, respectively, having legs 31c and 31d made of metal wire or synthetic resin material as in FIG. The above back hole button 3c is the leg body 31c
The tip end thereof is configured such that the thickness gradually increases from one end in the width direction to the other end, and one end in the width direction serves as a recess 32c for locking the thread A. On the other hand, the back hole button 3d is formed by recessing one end in the width direction of the tip of the leg 31d to form a recess 32d for locking the sewing thread A at a position eccentric to one side in the width direction of the leg 31d. ing.

In the back hole buttons 3b to 3d, the legs 31b to
When forming 31d from a synthetic resin material, it can be easily formed into the shape shown in the figure by molding. Further, when the legs 31b to 31d are formed of metal wire, they can be easily formed from a band-shaped metal wire by press working. For example, in order to form the leg body 31b with metal wire, the fourth
As shown in Figures A to C. After forming the protrusion 34b by laterally pressing the protrusion 41 in which the vicinity of the middle part of the strip-shaped metal wire 4 protrudes from the left and right, the metal wire 4 is bent as appropriate to form the concave part. 32b is formed. In addition, 42, 42
is a mounting part for fixing to the back surface of the button body by adhesive or other means.

Further, the leg 31b' shown in FIGS. 5A to 5C is a modification of the leg 31b described above, in which the vicinity of the middle part of the strip metal wire 4' is forged from below to protrude the middle part in the width direction. Then, by bending the bulge 34
b' and a recessed portion 32b'.

Also in the back hole buttons 3a to 3d configured as described above, the same effect as the back hole button 3 described above can be obtained.

In each of the embodiments described above, it is preferable that the leg tip end surface 33 be formed as flat as possible, but it may be slightly rounded near the corners for reasons of design and manufacturing.

As explained above, in the back hole button of this invention, the locking part of the sewing thread formed on the leg body is formed eccentrically to one side in the width direction of the leg body, so that the locking part is moved upward in the vertical direction. By attaching it in this position, it is possible to prevent the edge of the button hole on the front fabric from losing its shape or fraying, and it also prevents the button head from hanging down as much as possible even if the sewing thread becomes loose. This is what I did.
