In recent years, there have been many incidents of invading schools and killing students. As measures against this, lightweight aluminum piercing has begun to be adopted at educational sites.
For intruders who wield weapons such as knives, protective shields may be sufficient if they are strong police officers or so-called guardmen, but protective shields are not sufficient in educational settings where there are relatively many women. .
In the first place, the protective shield is only for preventing yourself from being familiar, and is not suitable for faculty and staff to protect children.

On the other hand, since the piercing has a long handle, it is possible to directly suppress the intruder's own movement while keeping the intruder away, and it is difficult for me to swing around the weapon. is there.

In recent years, the pierced crotch is not intended for the throat to avoid danger, but has a shape for the chest and torso, and the U-shaped part is greatly expanded and curved in an arc (hereinafter referred to as an arc-shaped curve). Therefore, although it is lightweight, it has become a big swing.

For this reason, there is another difficulty in keeping the arc-shaped curved portion of the piercing crotch in a horizontal state, which is a proper use state, by simply adjusting the length of the long handle. For this reason, there is a difficulty in using the piercing crotch appropriately and effectively while keeping the arcuate curved portion in a horizontal state.

  Further, since the pierced crotch itself is reduced in weight, more pressing force than before is required to hold down the intruder. From this point, it is difficult for the less powerful person to use the pierced crotch.

  The present invention has been made for the purpose of solving the above-mentioned problems. Just by holding the handle lightly without squeezing the handle, the arcuate curved portion becomes an appropriate horizontal state, and even if used by a person who is less powerful than the conventional one, The purpose is to provide a piercing crotch with increased pressure.

The invention of the stabbed crotch according to claim 1 is the stabbed crotch provided with an arc-shaped curved part at the tip of the handle , wherein the handle is always held lightly without being clamped, and the both ends of the handle are always directed in the vertical direction by its own weight. is such that the horizontal state, the handle, characterized in that the curved plane of the arcuate curved portion is provided in the axis rearward of the at least handle fell vertically from the curved plane in the horizontal state.

According to a second aspect of the present invention, in the piercing according to the first aspect, the axis of the handle begins to fall vertically from the curved plane from any part between the front end of the handle and the vicinity of the center of the handle. It is provided so that it may become an axis.

According to a third aspect of the present invention, in the piercing according to the first or second aspect, the axis of the handle is arcuate or substantially letter-shaped.

According to a fourth aspect of the present invention, in the piercing crotch having an arc-shaped bending portion at the tip of a handle, a suppression convex portion is provided on the curved inner surface side of the arc-shaped bending portion.

According to a fifth aspect of the present invention, in the piercing according to any one of the first to third aspects, a suppression convex portion is provided on the curved inner surface side of the arc-shaped curved portion.

The invention according to claim 6 is characterized in that, in the piercing according to claim 4 or 5, the suppression convex portion is provided at the center of the arcuate curved portion corresponding to the front end of the handle.

A seventh aspect of the invention is characterized in that, in the piercing according to any one of the fourth to sixth aspects, the suppression convex portion is a resilient material.

According to an eighth aspect of the present invention, in the piercing according to any one of the fourth to seventh aspects, the suppression convex portion is detachably attached.

According to each of the inventions of claims 1 to 3 and claims 5 to 8, since the handle is bent, both ends of the handle are always directed in the vertical direction by its own weight. The arcuate bend is always in the proper horizontal state by just holding it lightly.
Therefore, even if it is a weak person, the arcuate curved portion is always in an appropriate horizontal state, so that the piercing can be used easily and appropriately.

In addition, the handle is used in a state where both ends of the handle face downward, and the pushing force toward the tip of the handle (manufacturing pressure) acts in the direction of pushing down at the arcuate curved portion.
Compared to the conventional straight pattern that works only in a straight line, the structural pressure is increased.

According to the inventions of claims 4 to 8, in any case, since the suppression convex portion further restricts the movement of the person caught by the arcuate curved portion, the suppression is relatively easy even by a weak person. can do.

The present invention will be described on the basis of an embodiment of aluminum made lighter piercing crotch.
1 is a plan view of the pierced crotch, FIG. 2 is a side view of the pierced crotch in a horizontal state, FIG. 3 is an enlarged side view of the convex part for suppression, and FIG. 4 is an exploded view of the convex part for suppression.

  1 and 2, reference numeral 10 in FIG. 1 denotes an arcuate curved portion of a pierced crotch, which is greatly expanded as shown in FIG. 1 so that it is not a person's neck (throat) but a chest or torso, and is arcuate. The shape is curved.

The stab handle 20 provided with the arcuate curved portion 10 at the tip thereof is at least the rear of the handle when the curved plane of the arcuate curved portion 10 is in a horizontal state (both curved tips are at the same height position). The part 21 is provided by being bent so as to draw an axis that is vertically lowered from the curved plane.

The axis X of the handle 20 of this embodiment shown in FIG. 2 begins to slowly fall in the vertical direction from any part between the front end 22 of the handle 20 in the horizontal state and the vicinity of the center portion 23 of the handle. It is formed so as to draw an axis line lower than the curved plane.
Further, the axis X of the handle 20 is not limited to a gentle arc shape as shown in the figure, and may be provided by being bent into a substantially square shape.

According to this embodiment, by bending the handle as described above, the handle is under its own weight and both ends thereof are always lowered in the vertical direction, and as a result, the arcuate curved portion 10 (its curved plane) naturally becomes horizontal. Therefore, the arc-shaped curved portion is always in the proper horizontal state (both curved tips are at the same height position) simply by holding the handle lightly without tightening.

Therefore, even if it is a weak person, since an arcuate curved part will be in an appropriate horizontal state without being conscious, it can be used easily, appropriately and effectively.
Also, the force (manufacturing pressure) that pushes toward the tip of the handle acts in the direction of pushing down at the arcuate curved portion, so that it is structurally higher even with the same king pressure than the conventional straight handle that works only linearly. A control pressure can be obtained.

In addition, although the arc-shaped curved part 10 and the handle | steering-wheel 20 of this Example are shape | molded with the aluminum material, it may not be restricted to this but a wooden material and other materials may be used.

On the curved inner surface side of the arcuate curved portion 20 of the pierced crotch, a suppression convex portion 30 is provided as a restraining tool for restraining the resistance action of the person supplemented by the arcuate curved portion 20. In this embodiment, only one pressure-suppressing convex portion 30 is provided so as to be correspondingly positioned at the center portion on the curved inner surface side of the arc-shaped curved portion 10, that is, at the front end of the handle 20 on the extended line of the handle 20. However, the present invention is not limited to this, and several enemies may be provided.

In addition, since the suppression convex portion 30 is not intended to injure the supplementer, it is preferably made of a resilient material that does not cause injury, such as hard rubber or resin.

As shown in FIGS. 3 and 4, the pressure-control convex portion 30 of this embodiment is detachably mounted.
Reference numeral 31 in the drawing is a mounting plate fixed to the front end portion (tip end portion) 31 of the handle 20, and the pressure-control convex portion 30 formed in a substantially triangular plate shape is attached by a bolt 32 and a nut 33. .

Therefore, the convex portion 30 for suppressing pressure can be used even when the bolt 32 and the nut 33 are removed and removed.
In addition, although the pressure suppressing convex portion 30 has a triangular plate shape, the shape is not limited thereto, and may be a rod shape with a rounded tip, for example.
The arcuate curved portion 10 is also fixed to the mounting plate 31.

INDUSTRIAL APPLICABILITY The present invention can be widely used as a security device that does not damage the opponent.

It is a top view of piercing. It is a side view of the state which made the thighs horizontal. It is an enlarged side view of the convex part for suppression. It is an exploded view of the convex part for suppression.
