Abstract

PROBLEM TO BE SOLVED: To improve a hit rate of a blowgun. SOLUTION: A blowgun guide section 4 and a lip contact end side section 2 are displaced up and down by a fraction corresponding to upper and lower displacements of a mouth 22 and an eye 23 of a human being 21 or upper and lower displacements corresponding to the foregoing displacements, so that in the state of the human being where the mouth 22 is touched with a lip end 2a of a blowgun cylinder 1 eyes 25 of the human being and the center line of the blowgun guide section 4 are made flush with or substantially flush with each other, so that if a portion to be shot by the blowgun 6 is brought onto an extension line of the eyes 25 and the blowgun guide section 4, the blowgun 6 shot from the blowgun guide section 4 is shot toward the portion to be shot by the blowgun 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blowing cylinder for a blowing arrow.

[0002]

Disadvantages of the prior art Since the conventional blowing cylinder of a blowing arrow is a simple straight cylinder, it has the following disadvantages. When the mouth is attached to the mouth end of the blow cylinder, a vertical shift between the center line and the line of sight of the blow cylinder is caused by the vertical shift between the human mouth and the eyes, so the shot is fired from the blow cylinder. In order for the arrow to be directed to the portion where the arrow is shot, the direction of the blow cylinder must be shifted downward by the above-described vertical shift. However, it is difficult to adjust it, which has led to a decrease in the hit ratio.

[0003]

The present invention employs the following means to solve the above-mentioned drawbacks. The invention according to claim 1 has a lip end side portion having a lip end for attaching a mouth,
An arrow guide portion for guiding an arrow, which is connected to the mouth end portion via a connecting portion, has an arrow guide portion and a mouth edge side portion, which are vertically displaced between a human mouth and an eye or It is shifted upward and downward by an amount corresponding to the vertical shift substantially corresponding thereto. The invention according to claim 2 is the one according to claim 1, wherein the arrow guide portion is detachably attached to the connecting portion. According to a third aspect of the present invention, a first projection is provided on an upper portion of a front end of the arrow guide portion, and a second projection is provided on an upper portion of a rear end of the arrow guide portion.
3. The method according to claim 1, wherein an imaginary line connecting the upper end of the projection is parallel to a center line of the arrow guide portion.

[0004]

According to the present invention, the following effects can be obtained by the above configuration. According to the invention of claim 1, since the arrow guide portion and the lip end side portion are vertically displaced by an amount corresponding to the vertical displacement between the human mouth and the eyes or the vertical displacement substantially equivalent thereto, Since the line of sight and the center line of the arrow guide portion can be at the same or almost the same height position in a state where the mouth is attached to the mouth end of the blow cylinder, a portion that shoots an arrow on the line of sight and an extension of the arrow guide portion If you take, the arrow fired from the arrow guide will be fired toward the part that shoots the arrow,
The hit rate can be dramatically improved. According to the second aspect of the present invention, the arrow guide portion can be separated from the connecting portion and the arrow can be easily inserted into the rear end of the arrow guide portion. According to the third aspect of the present invention, the hit ratio can be further improved by using the first protrusion and the second protrusion.

[0005]

Embodiments of the present invention will be described below. In this description, the front means the right side of FIG. 1 and the rear means the left side.

The blowing cylinder 1 has a lip end 2a having a lip end 2a to which a mouth 22 of a human 21 is attached, and an arrow for guiding the arrow 6 connected to the lip end side 2 via a connecting portion 3. And a guide portion 4. The arrow guide portion 4 is detachably attached to the connecting portion 3 by, for example, the following means. That is, the center line of the front end portion 3a of the connecting portion 3 is made parallel to the center line of the mouth end side portion 2, and the rear end portion of the arrow guide portion 4 is detachably fitted to the front end portion 3a. I have. Although not shown, the front end 3
When the rear end portion of the arrow guide portion 4 is fitted to the inner surface of the front end portion 3a of the connecting portion 3 or the rear portion of the arrow guide portion 4, the first protrusion 7 and the second protrusion 8 described later always face upward. A fitting small ridge (for positioning) parallel to the center line of the front end 3a is formed on one of the outer surfaces of the ends, and a fitting groove into which the fitting small ridge is fitted on the other end. Are formed. The arrow guide portion 4 and the lip end side portion 2 are vertically displaced by an amount corresponding to a vertical displacement between the mouth 22 and the eye 23 of the human 21 or a vertical displacement substantially equivalent thereto. More specifically, the center line of the arrow guide portion 4 and the center line of the lip end side portion 2 correspond to the human 2
The first mouth 22 and the eye 23 are vertically displaced by an amount corresponding to the vertical displacement or approximately the vertical displacement corresponding thereto.

A first projection 7 is provided on the upper part of the front end of the arrow guide 4.
Is located on the upper end of the rear end of the arrow guide 4 (the front end 3a of the joint 3).
The second projection 8 is provided at a portion other than the portion that fits into the first projection 7, and an imaginary line connecting the upper end of the first projection 7 and the upper end of the second projection 8 is parallel to the center line of the arrow guide portion 4. It has been made like that.

[0008]

Next, a method of using the embodiment of the present invention will be described. The arrow guide part 4 is removed from the connecting part 3, and the arrow 6 is inserted from the rear end of the arrow guide part 4 so that the tip of the arrow 6 faces forward. Thereafter, the arrow guide part 4 is connected to the connecting part 3.
Connect to After that, the kissing end 2a is held by the mouth 22,
The line of sight 25 passes through the upper end of the second protrusion 8 and the upper end of the first protrusion 7 and hits a portion where the arrow 6 is shot (hereinafter referred to as a target). After such preparation, if air is strongly blown into the blowing cylinder 1, the arrow 6 flies toward the target and hits it. It should be noted here that the line of sight 25 passes through the upper end of the second protrusion 8 and the upper end of the first protrusion 7 and hits the target, and the target can be positioned where the arrow 6 flies. is there. That is, in the conventional blowing cylinder, it was necessary to shift the direction of the blowing cylinder downward by the amount of vertical displacement between the mouth 22 and the eye 23 of the human 21, but such a work is unnecessary. is there.

[0009]

[Modifications and the like] Modifications and the like will be described below. (1) The first projection 7 and the second projection 8 may not be provided. In this case, in use, the line of sight 25 hits the target through the upper end of the arrow guide 4 (the upper end parallel to the center line of the arrow guide 4) or slightly above. (2) The connection angle of the connecting portion 3 with respect to the butt end side portion 2 and the arrow guide portion 4 is arbitrary. (3) The length of the mouth end side portion 2 and the length of the arrow guide portion 4 are arbitrary. (4) The arrow guide part 4 may be integrally fixed to the connecting part 3. In this case, the arrow 6 is inserted from the front end of the arrow guide 4 and is moved to the rear end of the arrow guide 4. (5) The connecting portion 3 may be telescopically expandable and contractible so that the vertical displacement (distance) between the butt end side portion 2 and the arrow guide portion 4 can be adjusted.
