Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a button used to fasten a seam of clothing.

[0002]

2. Description of the Related Art A conventional button is a disk-shaped button made of a shell, a metal, a nut, a synthetic resin, casein, or the like at one of the seams at a seam of clothing. Then, the buttons are sunk into a buttonhole or a button loop provided on the other side of the joint to hold both buttons.

In the above-mentioned conventional buttons, since it is relatively difficult to make the button dive into a buttonhole or the like at the time of attachment / detachment, both hands or the hands of another person are required for attachment / detachment of the button. It was very difficult. For this reason, especially infants, the elderly and disabled persons have had to rely on others to attach and detach the buttons. In addition to the above-mentioned buttons, there are other means to lock the seams of clothes, such as hooks and snaps, which make the locking method easier. The operation is still difficult.

[0004] In order to reduce such inconvenience, there is a magnetic button utilizing the magnetic force of a magnet. This magnetic button is a combination of a male button with a base plate-shaped permanent magnet mounted in a bottomed cylinder, and a female button with a plate made of magnetic metal in a similar bottomed cylinder, The male button and the female button are made detachable by the attractive force acting between the permanent magnet and the magnetic metal plate. The bottomed cylinders of the male button and the female button are provided with locking means for the button mounting cloth, for example, a hole or an annular body through which a thread passes.

The above-mentioned conventional magnetic button is engaged only by the attracting force of the magnetic force acting between the permanent base of the male button and the plate made of the magnetic metal of the female button in the state where they are simply in contact with each other. Is what you do. On the other hand, since the attractive force of the permanent magnet is weak against lateral sliding, the conventional magnetic button has a disadvantage that the male button and the female button are relatively easily disengaged due to the lateral sliding.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and can be easily and reliably attached and detached to infants, the elderly and disabled persons by making detachment as easy as possible with one hand. An object of the present invention is to provide a magnetic button that improves the engagement between a button and a female button.

[0007]

According to a first aspect of the present invention, there is provided a permanent magnet having a plate-like shape in a bottomed cylinder having means for engaging a button mounting cloth. A magnetic button in which a male button having a male button mounted thereon and a female button having a plate made of a magnetic metal mounted in a bottomed cylinder having a locking means to the button mounting cloth are detachably combined. The cylinder and the bottomed cylinder of the female button are formed of a non-magnetic material, the male button is formed in a convex shape by projecting a permanent magnet from the open end of the bottomed cylinder, and the female button is formed by changing the inner diameter of the bottomed cylinder to the permanent diameter of the male button. A magnetic button, characterized in that a plate made of a magnetic metal having the same outer diameter as the magnet and mounted in the bottomed cylinder is disposed inside the bottomed cylinder opening end and formed in a concave shape.

According to a second aspect of the present invention, the bottomed cylinder of the male button and the bottomed cylinder of the female button are formed of a non-magnetic metal,
The locking means for the male button and the female button is a V-shaped part having a corner directed toward the center in an annular area between the periphery and the center of the bottom wall of the metal bottomed cylinder.
A plurality of V-shaped cuts are provided at equal intervals, and the cut pieces formed by the V-shaped cuts are erected in a mountain shape, and are used as return locking pieces inserted into the button mounting cloth. Item 6. A magnetic button according to the means of Item 1.

The operation of the above means will be described below. According to the magnetic button of claim 1,
Since the male and female buttons are engaged by the attractive force of the magnetic force acting between the permanent magnet of the male button and the plate made of the magnetic metal of the female button, it is only necessary to bring one of the male and female buttons close to the other. The attraction force of the permanent magnet acts in the direction in which the two are fitted, and the two can be easily engaged. The magnetic button has the inner diameter of the bottomed cylinder of the female button equal to the outer diameter of the permanent magnet of the male button, so that the permanent magnet of the male button can be fitted into the bottomed cylinder of the female button. In this state, a convex male button is fitted into a concave female button. Therefore, there is no side slip between the male button and the female button in the engaged state. The magnetic button can be strongly engaged because the magnet is weak against sliding in the horizontal direction and the effective magnetic flux is maximized by preventing leakage magnetic flux.

According to the magnetic button of the present invention, the locking piece erected from the bottom wall is pierced into the button mounting fabric and then bent substantially in parallel with the bottomed cylinder bottom wall, thereby forming the bottom wall with the bottom wall. The button mounting cloth is sandwiched between the locking pieces, and the male button and the female button are mounted on the button mounting cloth. At this time, the locking piece may be folded toward the center of the bottom wall, or may be folded in the opposite direction, that is, toward the outer edge. When the locking piece is folded toward the center of the bottom wall,
Since the tip of the locking piece does not protrude outside the button, it is safe. As described above, the magnetic button according to the second aspect does not require any other mounting tool other than the button for mounting the button, and does not require a sewing operation with a thread or the like, and can be easily mounted. . In addition, since the bottomed cylinders of the male button and the female button are made of metal, the above-mentioned bending plastic processing of the locking piece can be performed, and the locking strength can be obtained at the same time. Furthermore, since the V-shaped locking piece is provided in the annular area between the peripheral centers of the bottomed cylindrical bottom wall with the V-shaped corners directed toward the center side and equally spaced, the V-shaped locking piece is inserted and folded back into the button mounting cloth. In this state, all the tips of the plurality of locking pieces are directed toward the center of the bottomed cylindrical bottom wall or toward the opposite peripheral direction. Paying attention to one locking piece, the button mounting fabric is easy to fall out in the direction of folding back of the locking piece, but the direction in which each locking piece is easy to separate is different, and when folded back to the center, all the locking pieces are easy to pull out The direction is the center direction of the bottom wall, and when folded in the peripheral direction, the direction in which all the locking pieces can easily come out is in the peripheral direction, so the movement of the mounting cloth is restricted to each other, and it may fall off from the button mounting cloth. Can be prevented.

FIG. 1 is a perspective view showing a magnetic button according to the embodiment, FIG. 2A is a rear side perspective view showing a female button of the magnetic button of FIG. 1, and FIG. FIG. 3 is a back side perspective view having a partial cross section showing a female button of the magnetic button of FIG. 1, FIG. 3 is a sectional view taken along the line AA of the magnetic button of FIG. 1, and FIG. 4 is an engaged state of the magnetic button of FIG. FIG. 5 is a bottom view showing a cut formed in the bottomed cylindrical bottom wall of the male button of the magnetic button of FIG. 1, and FIG. 6 (a) is a male button of the magnetic button of FIG. FIG. 6B is a side view showing a state in which an incision formed in the bottomed cylindrical bottom wall of the button is made, and FIG. 6B is a bottom view of FIG. Although the magnetic button is drawn relatively thick in FIGS. 1 to 6 for ease of explanation, it is actually about the same thickness as a general button.

The magnetic button includes a male button 1 and a female button 2 as shown in FIG. As shown in FIGS. 1 to 3, the male button 1 includes a bottomed cylinder 3 made of non-magnetic austenitic stainless steel, and a cylindrical ferrite magnet 4 fitted in the bottomed cylinder 3. The bottomed cylinder 3 is flat with a small height relative to the diameter, while the ferrite magnet 4 is also relatively flat.
However, the height was longer than the depth of the bottomed cylinder 3. Therefore, when the lower surface 5 side of the ferrite magnet 4 is fitted into the bottomed cylinder 3, the ferrite magnet 4 extends from the open end 7 of the bottomed cylinder 3.
The upper surface 6 protrudes and becomes convex as a whole. Specifically, the bottomed cylinder 3 has an inner diameter of 10.0 mm, a depth of 2.0 mm,
The thickness of the peripheral wall and the bottom wall was 0.4 mm, and the ferrite magnet 4 was 10.0 mm in outer diameter and 3.6 mm in height.

The female button 2 is shown in FIGS.
As shown in FIG. 3B and FIG. 3, a bottomed cylinder 8 similar to the bottomed cylinder 3 of the male button 1 and an iron plate 9 such as a disk-shaped soft iron laid on the bottom of the bottomed cylinder 8 are formed. . Specifically, the size of the bottomed cylinder 8 was the same as the size of the bottomed cylinder 3, and the iron plate 9 was formed with an outer diameter of 10.0 mm and a thickness of 0.4 mm. Therefore, the female button 2 has a depth of 1.6 m as a whole.
m (bottom).

The convex male button 1 and the concave female button 2
Can be fitted so that the open end 7 of the bottomed cylinder 3 and the open end 10 of the bottomed cylinder 8 and the upper surface 6 of the ferrite magnet 4 and the surface 11 of the iron plate 9 match as shown in FIG. In this state, the male button 1 and the female button 2 can be engaged by the attractive force acting between the ferrite magnet 4 and the iron plate 9. Since the attractive force of the ferrite magnet 4 acts more as the male button 1 and the female button 2 are brought closer to each other, by bringing one of them close to the other with one hand, the two can be naturally attracted and engaged.

Since the magnetic button composed of the male button 1 and the female button 2 is used for the purpose of making the seam of the clothing detachable, the male button 1 is provided on each side of the seam.
And the female button 2 must be separately locked. The means for locking the male button 1 and the female button 2 to a cloth or the like will be described below. However, since the male button 1 and the female button 2 are the same locking means, only the male button 1 will be described. In FIGS. 5 and 6 (a) and (b) used in this description, the ferrite magnet 4 is omitted and only the bottomed cylinder 3 is drawn for simplicity. First, a V-shaped cut 13 is formed in the bottom wall 12 of the bottomed cylinder 3 as shown in FIG. The V-shaped cuts 13 are formed so as to radiate from the center side of the bottom wall 12 to the outer peripheral side, and are provided at five equal intervals. V-shaped cut 1
3 specifically, the V-shaped corners are placed 1..
5 mm apart, and both ends of the V-shape are 0.9 mm from the outer circumference.
2 mm apart from each other at the inner position of the inner leg. Angled locking piece 14 formed by this V-shaped cut 13
Is bent outward from the bottom wall 12 of the bottomed cylinder 3, as shown in FIGS. 6A and 6B, and the tip 15 of the locking piece 14 is slightly bent toward the center of the bottom wall 12. I do. In this state, each locking piece 14 of the bottom wall 12 is pierced into a cloth or the like, and then bent back toward the center of the bottom wall 12 so as to be substantially horizontal with the bottom wall 12, so that the male button 1 and the female button 2 can be clothed. Etc. can be locked. At this time, 5 provided at equal angular intervals on the bottom wall 12
Since all of the locking pieces 14 are bent back toward the center of the bottom wall 12, the locking pieces 14 can be hooked on a cloth or the like from five different directions and locked reliably.

While the embodiment of the present invention has been described above, the embodiment of the magnetic button according to the present invention is not limited to this. For example, the bottomed cylinder 3 and the bottomed cylinder 8 are not limited to those made of austenitic stainless steel, but may be any non-magnetic one. Further, the iron plate 9 may be another material as long as it is a material having magnetism. Further, the invention is not limited to the ferrite magnet 4, and various permanent magnets may be used. The V-shaped cuts 13 formed in the bottom wall 12 of the bottomed cylinder 3 and the bottomed cylinder 8 are not limited to five. However, at two places or less, the locking force to the button mounting cloth is small, and at six places or more, it is necessary to reduce the V-shaped width so that the cloth or the like is not cut into a circle at the root of the locking piece 14. is there. Further, the locking piece 14 may be bent in the direction opposite to the center direction of the bottom wall 12, that is, in the outer peripheral direction, and locked to the button mounting cloth. Also,
The bottomed cylinder 3 and the bottomed cylinder 8 may be square cylinders.

The bottomed cylinders 3 and 8 of the male button 1 and the female button 2 are replaced with non-magnetic material by magnetic material,
May have magnetic poles at the upper and lower ends so that the inner wall surface of the bottomed cylinder 3 of the male button 1 does not contact the side surface of the permanent magnet 4. In this manner, the open end 7 of the bottomed cylinder 3 of the male button 1 becomes one of the magnetic poles of the permanent magnet 4, and the male button 1 strongly closes the open end 10 of the bottomed cylinder 8 of the female button 2 formed of a magnetic material. Can be engaged. For this reason, even if the high-grade permanent magnet 4 having a large magnetic force is not used, it is possible to obtain a sufficient fastening force as a button by maximizing the magnetic force.

[0018]

According to the magnetic button of the present invention, since the male button and the female button are engaged by the attraction of the permanent magnet, the male button and the female button can be easily formed simply by bringing them closer. It can be engaged without shifting, and can be attached with only one hand. Therefore, unlike the conventional buttons, the infant, the elderly, the disabled, and the like can attach and detach the buttons themselves. Further, since the magnetic button has a structure in which the concave female button and the convex male button are fitted, there is no side sliding of the male button and the female button at the time of engagement, and the magnetic force of the permanent magnet is not increased. Also, a relatively strong engaging force can be obtained.

According to the magnetic button of the second aspect, the male button and the female button can be securely attached to a cloth or the like with a simple structure that can be hooked by a V-shaped cut provided on the bottomed cylindrical bottom surface of the female button. Therefore, troublesome operations such as sewing with a thread like a conventional button and forming a buttonhole can be omitted.
