Description

[Detailed description of the invention] The present invention consists of a button body, a leg body, and a fastening body,
This invention relates to a button with a simple structure that allows easy, quick and strong attachment to clothing.

Conventionally, buttons have been sewn onto clothing using thread, but such sewing work is labor-intensive and inefficient, and buttons often fall off or get lost due to thread breakage. In order to solve this problem, some proposals have been made in which the button body and the garment are fixed by a fastening member instead of using thread, but the conventional proposals are based on the button body and the fastening member. It is practically extremely difficult to fix the device to the vehicle, and there is little feasibility. It is known that a metal ring is used as a fastening member to ensure a strong attachment, but it has the disadvantage that it looks bad and can only be used for uniform clothing such as school uniforms.

The present invention enables the button body and the leg body to be firmly attached by providing the fixing body with a shaft rod that can support the protrusion of the leg body in a locked state with the button body. An embodiment of the present invention will be described below with reference to the drawings for the purpose of providing a button.

In the figure, the button 1 of the present invention consists of a button body 2, legs 3, and a fastening body 4. The button body 2 is made of metal,
Substrate 5 in a well-known shape such as a disk shape formed by cutting or molding using natural materials such as horn, glass, and ceramics, or artificial materials such as acetal resin, acetate, polyester synthetic resin, and acrylic resin.
In addition, in this example, the lower surface of the base body 5 is formed into a curved surface facing slightly upward, and at the center of the lower surface there is a narrow insertion portion 6 consisting of a circular hole, and a narrow insertion portion 6 formed at the upper part facing inward and outward. A blind hole-like recess 9 is formed in which a locking part 7 having a slope 7a inclined in the direction and expanding in width and a circular hole part 9 provided in the upper part of the locking part 7 are connected.

The leg body 3 is a molded product made of a synthetic resin such as acetal resin that is strong, elastic, and highly resistant to creep. For example, two protrusions 13, 13 are provided oppositely to each other, and a flange 15 is provided around the outer periphery of the lower end of the base 12. The protrusion 13 has an inner surface 1 that extends upwardly from surfaces 11a, 11a on the opposing long sides of the inner hole 11.
3a and has a semi-cylindrical shape that is centered at the center of the inner surface 13a and bulges outward with a smaller radius than the base 12, and its outer edge 13b is located at the base 1.
It protrudes outward from the outer peripheral edge 12a of No. 2. Further, the protrusion 13 has a concentric arc 12 on the upper surface 12b of the base 12 with a diameter slightly smaller than the outer diameter of the base 12.
By cutting off the lower part of the outer circumferential surface into an arc so that the lower ends intersect at point c, an outwardly facing oblique part 17 that fits into the locking part 7 is formed. Note that the protrusion 13

form. In this example, the engaging part 23 has a substantially horizontal locking surface 24a at its upper part, and a slope 24 that projects obliquely inward from its outer end via a hanging part 24b.
The sawtooth-shaped convex portions 24 having a diameter of c are provided in multiple stages. In addition, the inner hole 11 has protrusions 26, 26 swollen at the lower ends of the other short sides facing each other, and the inner surfaces 26a, 26a of the protrusions 26 and the opposing surfaces 11a, 11a are approximately square. form.

The fixing body 4 has a shaft rod 28 approximately in the center of the table piece 27.
is installed protrudingly. The shaft rod 28 has a surface 11 that faces the inner surfaces 26a, 26a of the protrusion 26 and the inner hole 11.
It is a prismatic body with a cross section that is almost equal to the square shape formed by the convex portions 24 and 11a, and has, for example, a mountain-shaped guide portion 29 at its upper end, and has opposite side surfaces 28a, 28a having a shape opposite to the convex portion 24. of,
A pawl portion 31 is formed in which groove portions 30 into which the convex portions 24 fit are provided in multiple stages. The shaft rod 28 has four corners chamfered and is molded integrally with the substantially elliptical base piece 27 using the same material as the leg body 3. Note that when the shaft rod 28 is pressed against the lower surface of the flange 15 of the leg 3 and the stand piece 27 with the clothing C sandwiched therebetween, its pawl portion 31 can be engaged with the meshing portion 23, and its upper end portion can be The length is set to reach the upper end of the protrusion 13 and support the inner surface 13a thereof. Therefore, the upper part of the shaft 28 is
By inserting the protrusion 13 into the inner hole 11 of the leg body 3, a support surface is formed that supports the inner surface 13a of the protrusion 13 fitted into the locking portion 7, which faces the inner hole 11.

However, when attaching the button 1 of the present invention, the leg body 3 is inserted into the recess 9 of the button body 2, and the leg body 3 is inserted into the protrusion 1 of the button body 2.
3 and 13 are inserted while being squeezed, the diagonal portion 17 engages with the locking portion 7, and the leg body 3 is fitted into the button body 2, and is temporarily fixed by the elastic force of the protrusion 13. After that, the fastening body 4 is inserted into the required position of the clothing material C from the back side, and the shaft rod 28 is inserted into the inner hole 11 of the leg body 3, and the clothing material C is attached to the stand piece 27,
Pressure is applied between the leg body 3 and the flange 15 of the leg body 3. Note that the shaft rod 28 has a side surface 28a on which the pawl portion 31 is provided.
The elastic piece 22 is inserted so as to face the elastic piece 22 side, so that the clothing material C is clamped and the pawl part 31 is engaged with the meshing part 23 to prevent it from coming off. By preventing the inward deformation of the protrusion 13, the oblique part 17 is fixed to the locking part 7 so that it cannot fall off, and the button body 2 and the leg body 3 are firmly connected without play. It sticks without any problem. The base 12 of the leg 3 can also form a neck wrap.

On the other hand, when replacing the button 1, the base piece 27 of the fastening body 4 is grasped and rotated 90 degrees. Both the leg body 3 and the attachment body 4 are small in size and are made of an elastic material such as synthetic resin in this example, so that the attachment body 4
can be rotated while deforming the protrusion 26 etc. by applying a strong torsional force, and due to this rotation, the 8th
As shown in the figure, the pawl portion 31 of the shaft rod 28 faces the other facing surfaces 11b, 11b of the inner hole 11, and the elastic piece 22 is deformed outward by the other surface 28b of the shaft rod 31. As a result, the engagement between the pawl portion 31 and the engaging portion 23 is released, and the fastening body 4 can be pulled out from the leg body 3. Therefore, the fastening body 4 is pulled, and the button body 2 is deformed inwardly while the projection 13 is deformed inwardly.
The leg body 3 can also be removed from the body.

In addition, in the button 1 of the present invention, as shown by the dashed line in FIG. Depending on the leg body 3 and button body 2
As shown in FIG. 10, the protrusion 13 can be formed into a prismatic shape and the recess 9 is formed into a rectangular hole of the same shape. As long as it has the oblique portion 17 and can engage with the locking portion 7, any shape such as a triangular shape can be selected. In addition to the rectangular hole, the inner hole 11 can also be of various shapes such as an ellipse, a triangle, a pentagon, etc. as long as it can prevent the fixing body 4 and the leg body 3 from rotating in a free state. A circular hole can also be used by providing the protrusion 26 and forming a non-circular portion for preventing rotation in a portion. At this time, the cross-sectional shape of the shaft rod 28 of the fastening body 4 can be changed as appropriate, and the number of the protrusions 13 and the elastic pieces 22 can also be changed accordingly. Furthermore, the meshing part 23 and the pawl part 31 can be engaged with each other to prevent them from falling off, such as saw teeth, U-shaped teeth, triangular teeth, etc.
Convex portions 24 such as arcuate teeth and groove portions 30 can be employed, and as shown in FIG. portion 23, the elastic piece 2
The button 1 of the present invention can be modified in various ways, such as by using one protrusion 24a on the button body 2, or by providing a decorative thread hole and a tying thread in the button body 2.

As described above, the button of the present invention includes a button body, a leg body, and a fastening body, and the rod of the fastening body is passed through the back side of the garment at a required location, and the button body is attached to the button body at the protruding end. By fitting the temporarily attached legs,
It can be easily and quickly attached with one touch, greatly improving work efficiency compared to sewing work using thread, and the protruding piece of the leg body can be prevented from returning by the shaft rod of the fastening body, making it easy to connect to the button body. Since it can be firmly fixed to the leg body, the attachment is more reliable than the various conventional fastening members proposed, and it is possible to provide a practical button with a simple structure. Furthermore, when the fastening body is made removable by rotating, the button can be easily replaced depending on the season or taste, improving the design, preventing discoloration of high-quality buttons during cleaning, etc., and making it easier to iron. It can have many effects such as making it easier.
