Description

[Detailed Description of the Invention] The present invention relates to a throwing tool for shooting games.

2. Description of the Related Art Throwing tools have been known that are formed into a flat plate shape and have a plurality of radially sharp protrusions.

However, since conventional throwing tools of this type are formed by punching out a single metal plate, they cannot be folded and require a large area when housed in a case or the like.

Furthermore, if one inserts a finger into the case in an attempt to take out a throwing tool housed in the case, the tip of the finger may hit a plurality of sharp protrusions and be injured, which is very dangerous.

The purpose of this invention is to eliminate the above-mentioned drawbacks of the conventional technology, to be able to stab the target reliably regardless of the direction, and to be able to fold it into a small size when not in use, and to be able to store it in a case, etc. To provide a throwing tool for shooting games that is easy to store and does not damage fingertips when handled.

Hereinafter, the present invention will be explained in detail based on the drawings.

The throwing tool 1 according to the present invention is composed of two blades, a first blade 2 and a second blade 3. The first and second blades 2 and 3 have a spindle shape with both ends sharp, and have exactly the same shape, but the first blade 2 and the second blade 3 have a spindle shape formed at the tip thereof. The directions of the sharp cutting edges 2a and 3b are different.

That is, the cutting edge 2a of the first blade 2 is formed to be located on the counterclockwise side when the first blade 2 is rotated counterclockwise about the longitudinal center. On the other hand, as is clear from FIG. 2, the other second blade 3 is located in the clockwise direction when the second blade 3 is rotated clockwise, opposite to the first blade 2. The cutting edge 3a is formed in this manner.

Note that, as is clear from FIGS. 1 and 2, the respective cutting edges 2a and 3a are provided on the outer surfaces of the first blade 2 and the second blade 3.

By the way, a through hole 4 is formed in the center of the first blade 2, and the first blade 2 is inserted across this through hole 4.
Arc-shaped elongated holes 5, 5 are formed on the widthwise side.

In addition, a through hole 6 is formed in the center of the other second blade 3 at a position corresponding to the through hole 4, and a through hole 6 is formed on the longitudinal side of the second blade 3 across this through hole 6. In this case, arc-shaped long holes 7, 7 are formed.

That is, the arc-shaped long holes 5, 5 and 7, 7 of the first blade 2 and the second blade 3 are on the same circumference and are out of phase by 90 degrees.

A shaft 8a of a push button 8 is slidably fitted into the through hole 4 of one first blade 2 from the outside of the first blade 2.

An annular recess 8c is formed on the lower surface of the head 8b of the push button 8, and a first spring 9 is elastically mounted between the recess 8c and the outer surface of the first blade 2.

Therefore, the push button 8 is given a force in a direction away from the first blade 2 by the force of the first spring 9.

Further, the shaft 8a of the push button 8 is also fitted into the through hole 6 of the other second blade 3.

Incidentally, a cap 10 is fitted into the arc-shaped long hole 7 of the second blade 3.

That is, the cap 10 is formed into a disk shape, and arc-shaped protrusions 10a are provided at opposing positions on the outer peripheral surface of the cap 10 so as to protrude in the same direction at right angles. The arc length of this arc-shaped projection piece 10a is approximately equal to the arc length of the arc-shaped elongated holes 5 and 7.

Further, a through hole 10b is formed in the center of the cap 10.

The cap 10 having such a structure has its bent portion 10a fitted into the elongated hole 7 of the second blade 3,
A second spring 1, which is weaker than the first spring 9, is provided between the cap 10 and the side surface of the second blade 3.
1 is loaded.

Note that the inner diameter of the through hole 10b of the cap 10 is smaller than the diameter of the shaft 8a of the push button 8.

Then, the through hole 10b is aligned with the axis of the screw hole 8d formed on the shaft end side of the shaft 8a.
The cap 10 is attached by screwing the screw 12 into the screw hole 8d from the outside of the cap.

Note that the length of the protruding piece 10a is approximately the same as the total thickness of the first blade 2 and the second blade 3.

Next, the operation will be explained.

First, when stored, as shown in FIGS. 7 to 11, the first blade 2 and the second blade 3 are completely overlapped, and have a spindle shape as a whole.

At this time, as is clear from FIG. 10, the projection 10a of the cap 10 is fitted into the elongated hole 7 on the second blade 3 side, but it is not fitted into the elongated hole 5 on the first blade 2 side. They are not aligned and are in contact with the sides.

That is, the long holes 5 and 7 are out of phase by 90 degrees. At this time, the first spring 9
is bent by the thickness of the first blade 2, and the second blade is bent by the thickness of the first blade 2.
The spring 11 is stretched.

If you want to open and fix the first blade 2 and second blade 3 in a cross shape from this state, rotate the first blade 2 and second blade 3 90 degrees in relatively different directions. The arcuate protrusion 10a of the cap 10 and the arcuate elongated hole 5 of the first blade 2 are in a state facing each other.

In this state, the push button 8 is pulled toward the outside of the first blade 2 by the force of the first spring 9, and since the force of the first spring 9 is greater than the force of the second spring 11, The cap 10 is pulled together via the screw 12, and the arcuate protrusion 10a
is fitted into the arc-shaped long hole 7 on the second blade 3 side.

Therefore, in this state, the first blade 2 and the second blade 3
will be locked in a criss-crossed state.

If you grab the throwing tool 1 in this locked state and throw it toward the target so that the entire tool rotates around the shaft 8a, the cutting edges 2a, 2a and 3a, 3a of the first blade 2 and second blade 3 will be released. At least one of the four cutting edges of the blade will surely sink into the target and pierce without fail.

Therefore, the player only has to think about rotating the throwing tool 1 when throwing, and there is no need to think about the direction so that the cutting edge faces the target.

On the other hand, if you want to fold the throwing tool 1 after throwing, press the push button 8 against the force of the first spring 9 to move the shaft 8a forward and move the cap 10 away from the second blade 3. The protruding piece 10a of the cap 10 can be removed from the elongated hole 5 of the first blade 2.

In this state, the lock is released, so the first
By relatively rotating the second blades 2, 3 in either direction, the two blades 2, 3 can be overlapped again as shown in FIG.

In this state, the throwing tool 1 may be housed in a case (not shown).

As is clear from the above explanation, according to the present invention, two spindle-shaped blades are rotatably connected at their center, and when they are crossed in a criss-crossed state, they can be automatically locked to maintain that state. If you throw it while rotating the whole thing without breaking the cross shape when throwing, you will be sure to hit the target with at least one of the four cutting edges.
The individual can pierce the target and hit the target.
Furthermore, when not in use, the push button can be pressed to disengage the protrusion from the elongated hole and the two blades can be folded into a slender, overlapping state, making it convenient to carry.
