Description

[Detailed description of the invention] Industrial applications The present invention relates to the brim of a bamboo sword.

Conventional technology In general, a shinai is formed into a tapered shape in the direction of the tip and the handle, and the brim of a conventional shinai is slid from the tip of the handle toward the fitted tip of the shinai, and is attached to the outer surface of the shinai. It was installed. In other words, since the brim is simply fitted onto the bamboo sword, there is a drawback that the engagement loosens and the brim falls off.

Problems to be Solved by the Invention An object of the present invention is to provide a shinai brim that is attached to a shinai via a temple and that does not have to worry about slipping or falling off even after long-term use.

Means for Solving the Problems In order to achieve the above object, the shinai brim of the present invention has an annular shape, has a temple attachment part, and
A shinai mount having a male thread groove formed on its outer circumferential surface, and a collar body that is fitted onto the outer surface of the shinai mount and has a female thread groove formed on its inner periphery to be screwed into the male thread groove. It has a configuration characterized by:

Function: Attach one end of the vine to the attachment part, and attach the shinai body by screwing to the shinai holder fitted to the outer surface of the shinai.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a shinai brim, which includes a shinai mount 2 and a shinai brim body 3.

The Shinai shinai attachment body 2 has a shinai attachment part 5 provided on one side of an annular member 4 that is open in the vertical direction, protruding upward from one end of the annular member 4, and a stopper 6 provided on the other side. A male screw groove 7 is formed around the outer periphery of the member 2.

As shown in FIG. 2, the temple attachment part 5 has a trapezoidal temple engagement member 8 that is widened at the bottom and a protruding piece 9 provided at its upper end. A hanging hole 10 penetrating the front and back surfaces is formed.

The protruding piece 9 is narrower in width than the upper side of the temple engagement member 8, and has a bulge 11 with a slightly larger diameter formed at the upper end, and a temple insertion hole 12 is formed in the bulge 11 in the width direction. be done. Further, a large number of anti-slip grooves 13 are formed on both left and right sides of the protruding piece 9 between the upper end of the temple engaging member 8 and the lower end of the bulging part 11, and a hanging member is formed in the center of the surface of the protruding piece 9. A vertical groove 14 is formed across the upper end of the stop hole 10 and the upper end of the bulging portion 11 .

As shown in FIG.
5 and an outer ring member 16, the inner ring member 15 has an annular shape with an inner diameter equal to the outer diameter of the shinai holder 2, as shown in FIG.
A female screw groove 17 is formed to be screwed into the male screw groove 7 of. Further, a fitting groove 18 is formed on the outer periphery, and fixing holes 19 are formed at four equal parts of the arc to pass vertically through the fitting groove 18.

As shown in FIGS. 4 and 5, the outer ring member 16 has an inner diameter equal to the outer diameter of the inner ring member 15, and has a projection on its inner periphery that fits into the fitting groove 18 of the inner ring member 15. A piece 20 is integrally provided, and a fixing hole 19' corresponding to the fixing hole 19 of the inner ring member 15 is bored in the projecting piece 20.

To assemble the collar body 3, the fitting groove 18 of the inner ring member 15 and the projection piece 20 of the outer ring member 16 are fitted, the inner ring member 15 is fitted inside the outer ring member 16, and the inner ring member 15 is fitted inside the outer ring member 16. A pin 21 or the like is inserted into the fixing holes 19, 19' of the member 15 and the outer ring member 16, and the two are fixed as shown in FIG.

Next, to explain how to use this collar 1, as shown in FIGS. 7 to 11, the handle of the shinai 22 is made of synthetic resin and has a protrusion 23 around the outer circumference of the opening end. A handle leather 24 is covered, and the annular member 4 of the Shinai shinai attachment body 2 is fitted onto the outer periphery of the handle leather 24 with the temple attachment portion 5 facing toward the tip of the sword. is brought into contact with. Then, the other end of the temple 25, which has one end fastened to the fore leather (not shown), is passed through the middle knot 26 (see FIG. 11) and tied to the temple mounting portion 5 of the shinai mounting body 2.

To attach the temple 25 to the temple attachment part 5, tie the temple 25 in a single knot to form a loop 27, insert the tip of the temple into the temple insertion hole 12 of the bulge 11 as shown in FIG. Insert into ring 27. next,
After folding it downward and passing it through the concave groove 14, as shown in FIG.
It is wound around from the upper end of the temple engagement frame member 8 toward the lower end of the bulging portion 11, and finally tied in the middle of the temple 25 as shown in FIG.

Then, as shown in FIG. 11, a shinai 2
Fit the collar main body 3 from the tip of the handle side of the shinai holder 2, and move the male thread groove 7 of the shinai mount 2 and the collar main body 3 in the direction of the arrow to the position of the stopper 6 of the shinai mount 2.
The brim main body 3 is fixed to the shinai attachment body 2 by screwing together with the male screw groove 17 of the brim body 3.

The inner ring member 15 of the shinai attachment body 2 and the collar body 3 is molded from a slightly soft synthetic resin such as nylon 12 so as to be tightly screwed together.

Therefore, during installation, both parts are bent and can be easily screwed together, but during use, they are tightened together and the collar body 3 will not fall off.

Further, the outer ring member 16 is molded from a synthetic resin that is harder than the shinai attachment body 2 and the inner ring member 15.

Furthermore, as another embodiment, an outer ring member 16 made of synthetic resin is embedded so that an inner ring member 15 made of synthetic resin is buried.
Alternatively, a part of the outer ring member 16 may be integrally poured into the fixing hole 19 formed in the inner ring member 15.

Effects of the Invention As stated above, the shinai brim of the present invention is
In addition to providing a temple attachment part on the shinai holder, a male thread groove was formed, and a female thread groove was formed on the inner peripheral surface of the brim body to be screwed into the male thread groove of the shinai holder, so that one end could be attached to the tip of the shinai. By attaching the other end of the vine tied to the vine attachment part, the sliding of the shinai attachment body fitted to the outer surface of the handle of the shinai is suppressed, and furthermore, the sliding of the shinai attachment body fitted to the outer surface of the shinai handle is prevented. movement is also regulated. Therefore, when using the shinai, the brim does not loosen and fall off from the tip of the handle.
