Description

[Detailed Description of the Invention] The present invention simplifies the installation work by inserting the mounting foot into a small horizontal notch previously provided in the mounting portion and attaching the retaining body to the tip of the mounting foot in a detachable manner. It is an object of the present invention to provide a new button device which can be used for various purposes, and which is particularly capable of reliably preventing attached buttons from being inadvertently rotated, tilted, or reversed. A tubular mounting foot is integrally provided in the center of the back surface, and a retractable pin that projects forward by a bullet built in the mounting foot is attached to the end face of the tip of this mounting foot. A pair of overhanging pins are attached to both sides of the tip, and a pair of anti-rotation pins are attached to the rear position of the mounting foot, slightly apart from the overhanging pins, to fit into the horizontal cutout made in the button attachment part of clothing, etc. A pair of pins for preventing over-insertion are provided as rotation prevention pins, respectively protruding in the same direction as the output pins, and also on the mounting foot at a position slightly rearward of the rotation prevention pins and engaging with the cutting edges on both sides of the horizontal notch. It has a flat, hollow shape with a button body protruding in orthogonal directions, and upper and lower walls.The upper wall has an insertion hole for the above-mentioned mounting foot, and the incisal edge of the insertion hole has an insertion hole for the above-mentioned overhang pin. The incisal edge of the insertion hole has a notch that allows the extension pin to pass through, and a recessed groove into which the extension pin fits is provided on the back side of the part of the incisal edge of the insertion hole that does not allow the extension pin to pass through. The main feature is that the retractable pin comes into contact with the lower wall surface when pushed in and compresses the bullet housed in the mounting leg.

In the illustrated embodiment, a tubular mounting foot 2 is integrally protruded from the center of the back side of a button body 1 formed by die-casting, and a bullet 3 built into the mounting foot 2 is attached to the end surface of the tip of the mounting foot 2. A retractable pin 4 protrudes forward, and a pair of overhanging pins 5, 5' are placed on both sides of the tip, and a button attachment part for clothes etc. is placed on the mounting foot 2 at a rear position slightly apart from the overhanging pins. Detent pins 7 and 7' that fit into the horizontal cutouts 6 made in the above are provided protruding in the same direction as the overhanging pins 5 and 5', respectively, and are also slightly rearward of the detent pins 7 and 7' on the mounting foot. Over-insertion prevention pins that engage with both incisal edges of the transverse perforation 6 are provided at the opposite locations, protruding in a direction perpendicular to the rotation stopper pins 7 and 7', and separately provided on the upper and lower wall surfaces 1.
0 and 10', a hollow and flat disc-shaped retaining body 11 is formed, and an insertion hole 12 for the above-mentioned mounting foot 2 is formed in the upper wall surface 10 of this retaining body 11.
Cuts 13, 13' are formed on the incisal edge of the insertion hole 12 to allow the overhang pins 5, 5' to pass therethrough, and cuts 13, 13' are formed on the incisal edge of the insertion hole 12 to prevent the overhang pins 5, 5' from passing through. Concave fitting groove 1 into which the protruding pins 5 and 5' fit into the back side of the
4 and 14', respectively, so that when the mounting foot 2 is pushed into the insertion hole 12 of the mounting foot 2, the projecting/retracting pin 4 comes into contact with the lower wall surface 10' of the retaining body 11 and is compressed.

That is, in the above description, the mounting foot 2 is inserted from the front side into a small horizontal notch 6 previously made in the attachment part of clothing such as school uniforms, and the attachment foot 2 is placed on the back side of the attachment part and is prevented from rotating. Pins 7, 7' are cut horizontally through holes 6.
Pins 8, 8' for preventing over-insertion
are secured to both incisal edges of the horizontal notch 6, and an insertion hole 12 is inserted at the tip of the mounting foot 2 to extend the overhang pins 5, 5'.
Align the permissible notches 13, 13' with the pins 5, 5', and push the extension pins 5, 5' into the upper wall surface 10 of the retaining body 11.
After reaching the inside of the retainer 11, turn the retaining member 11 slightly so that the projecting pins 5, 5' correspond to the recessed grooves 14, 14'. It can be attached to clothing such as school uniforms by inserting the projecting pins 5, 5' into the recessed grooves 14, 14' using the protruding force of 4.

Since the present invention is as described above, it goes without saying that buttons can be attached and removed from clothing extremely easily by simple operations as shown in the embodiments, but especially in the present invention, The mounting foot is equipped with a rotation stopper pin that fits into the horizontal mounting hole cut in the clothing and prevents it from rotating.This prevents the button from rotating inadvertently, tilting it, or turning it upside down, resulting in unsightly results. Also, since the mounting foot is provided with a pin to prevent over-insertion that locks on both incisal edges of the horizontal notch, this prevents the above-mentioned rotation stopper pin from being pulled out below the horizontal notch. It is possible to reliably prevent the occurrence of a situation in which the rotation stopper function is lost due to the rotation failure, and this has the effect of fully achieving the above-mentioned object of the present invention.
