Description

  The present invention relates to a piercing crotch that is a security device for controlling a thug.

A stab that is used when police officers or security officers control the behavior of thugs is generally equipped with a substantially U-shaped arm at the tip of the rod-shaped rod. The action is deterred by pressing the body of a thug against the wall or the like with the arm part while holding the. However, when the user's arm strength is weak against a thief, if the thief grips and resists the arm part or rod part, it will not be fully effective, and conversely the risk of deprivation of the piercing itself was there. In order to solve such problems, for example, devices such as Patent Documents 1, 2, 3, and 4 have been proposed.

Patent Document 1 has an axially slidable cylindrical member that is rotatably fitted on the outer periphery of the shaft member, and is fitted on the outer periphery of the tip side of the shaft member. And a compression coil spring provided on the inner peripheral side of the cylindrical member and capable of expanding and contracting in the axial direction of the shaft portion, and the compression coil spring abuts against a spring receiving member whose end is fixed to the shaft member. When the tip is brought into contact with the spring receiving portion formed on the tip side of the cylindrical member, when the thug grabs the cylindrical member and pushes it back, the cylindrical member rotates and the force to push back is compressed by the compression coil spring. Has been disclosed that has a structure of absorbing and relaxing.

Patent Literature 2 discloses a stab-like protective device in which a cylindrical member made of a synthetic resin tube or pipe is provided around a rod portion (corresponding to a rod portion) or a U-shaped portion (corresponding to an arm portion). However, even if a thug grabs these parts and tries to counterattack or escape, the tubular member rotates, slides or slides, so that no effect is exerted.

In Patent Document 3, a discharge part is provided near the tip of a bifurcated part (corresponding to an arm part) or a long handle (corresponding to a rod part), and an electric shock is applied to the thief by energizing the electrode of the discharge part from a power source built in the long handle A piercing that can be provided is disclosed. In addition, the capturing device described in Patent Document 4 has a large number of protrusions formed on a part of the capturing part (corresponding to the arm) and the rod-shaped shaft part (corresponding to the rod part), and it is painful to the gang who grabbed these. Can be given. These can be said to have aimed to prevent the capture device itself from being gripped by thieves.
Japanese Patent No. 3998260 Japanese Patent Laid-Open No. 2005-164204 Japanese Patent Laid-Open No. 2009-047342 Japanese Patent Laid-Open No. 2004-020856

  It can be said that the capturing device of Patent Document 1 aims at the effect of sealing both the push-back and twisting of the capturing device due to thugs. Here, the configuration in which the shaft member itself can be expanded and contracted by the action of the compression coil spring certainly has the effect of absorbing the force that the thug pushes back, but the purpose of the instrument is to finally push the thug against the wall etc. Is to restrain. However, in the case of the capture device having such a configuration, in order to maintain the state in which the restraint is successful, the user must continue to press the capture device against the violent force against the repulsive force of the compression coil spring. This is because if the user relaxes the force even a little, the repulsive force of the compression coil spring itself becomes a force that pushes back, and the restraint of the shaft member is relaxed, and there is a possibility of causing “play” that allows the thug to escape from the restraint. Because there is.

  On the other hand, due to the structure in which the shaft member itself is expanded and contracted by the compression coil spring, the distance between the user and the thief is between when the capture member is applied to the thief's body and until it is successfully restrained by pressing against the wall etc. It changes irregularly and the “feel” for the user becomes unclear. This is not desirable in actual suppression behavior.

In addition, when a thief once pressed against a wall or the like tries to escape or counterattack, in reality, the tubular member of the shaft member is not necessarily pushed back and twisted. When a thief grabs the tip of the capture member and twists it, the turning radius of the point of action of the force is larger than the radius of the shaft member gripped by the user's hand, so the user is easily deprived of the capture device The possibility increases. In this case, the rotating tubular member is useless in the first place.

  Furthermore, the structure provided with a compression coil spring or a cylindrical member on the front end side of the capture device is disadvantageous in terms of handling of the capture device itself in addition to the overall weight increase. It also causes damage and increases costs. From the practical point of view, the structure of the thigh is required to be lighter and more robust than anything else. Regardless of whether it is used by the police or security companies, the cost can be reduced if it is used in public facilities such as schools. There is a need to.

  It seems that the stab-like protective device described in Patent Document 2 can be reduced in weight with a simple structure. However, in order to rotate, slide, or slide the cylindrical member around the U-shaped part, the outer surface of the U-shaped part and the inner surface of the cylindrical member cannot be completely adhered due to the curved shape. On the other hand, as long as the cylindrical member is made of a tube or pipe made of synthetic resin, it deforms when it receives a strong external force and partially adheres to the outer surface of the U-shaped part, limiting the expected rotation, sliding, and sliding Is done. For this reason, for example, when a thief grabs both ends of the U-shaped part with a strong force with both hands, the intended effect of the tubular member is diminished, and there is a risk that the thief may easily counterattack or escape.

  The stabbed crotch described in Patent Document 3 is provided with a discharge part at the end of a long handle (corresponding to the rod part) or a bifurcated part (corresponding to the arm part), and the user operates the power open / close switch to energize it. It is suppressed by giving an electric shock due to discharge. However, suppression of such electric shocks, apart from humanitarian viewpoints, may not only cause cardiac arrest when used against a thief with a heart disease, for example, when used in rainy weather. In the worst case, there is an excessive risk of conducting an electric shock to nearby third parties. In addition, there are many problems in terms of practicality, such as a complicated structure, an increase in weight, a risk of failure, an effort to replace or charge a power source, and an increase in cost.

The capturing device described in Patent Document 4 exhibits an effect of making it difficult for a thug to grip by providing a large number of protrusions on the outer surface of a shaft portion (corresponding to a rod portion) or a capturing portion (corresponding to an arm portion). . This also seems to be able to reduce the weight with a simple structure, but the effect of the protrusion is diminished, for example, for a thief wearing thick gloves. In addition, as long as it has protrusions that are expected to be painful to thieves, the danger of inadvertent contact with the face of a user or a nearby third party cannot be excluded, and in narrow spaces such as indoors On the other hand, it may become a restriction on use. Of course, an increase in cost is inevitable.

The present invention was created for the purpose of solving such problems of the prior art.
Taking into account the actual situation of thief-controlled thugs, it is more effective to seal off the resistance to try to invalidate and pick up the stings by grabbing and twisting the arm part rather than pushing back the rod part due to thieves who are subject to repression. It is important to realize this with a piercing with a structure that is lightweight, robust, and as simple, simple and low-cost as possible. Also, considering the use of ordinary people who have not received special training other than police officers and security officers, the method of use needs to be simple and clear.

  The present invention was created in view of the problems of the prior art, and is lightweight, robust, simple, and low-cost that is difficult to be invalidated or picked up even if the arm is gripped and twisted by a thief. The object is to provide a structural piercing.

  First, the invention described in claim 1 is a stabbed stab for a thug that consists of a rod-shaped rod portion and a substantially U-shaped arm portion, and the axis of the rod portion is rotated around a part of the outer periphery of the rod portion. It has the cylindrical rotation holding part fitted so that rotation is possible as an axis | shaft, It is characterized by the above-mentioned.

The piercing is usually used by the user holding both the center portion and the end portion of the rod portion with both hands.
Even in the present invention, the user first grips the non-rotating gripping portion other than the rotating gripping portion of the rod portion to confront the gangster, and attempts to suppress the arm portion against the gangster's body. When a thief who is about to be suppressed grabs and twists the arm, the arm's radius of rotation is much larger than that of the rod, so the user must grip the rod against rotation. In the worst case, there is a danger that thugs will be taken up by thugs.

Therefore, when the arm part is grabbed by a thief, the user may change it to the rotary grip part as appropriate. Since the rotary gripping part is configured to be rotatable about the axis of the rod part as a rotation axis, even if a thug twists the arm part, the rotation is not transmitted to the rod part, and the user can continue to hold the piercing Yes, you can continue the suppression action without breaking your attitude. Also, in order for a thief to escape with a stabbed crotch, he has to release his hand from the arm. When the user releases the arm from the arm, the user immediately changes it to the non-rotating gripping portion of the rod, and again prepares the arm to resume the suppression action. The user can change the rod part by simply sliding the surface of the rod part to the rotary gripping part without releasing the hand from the rod part. It is also possible to replace it.

  Next, the invention described in claim 2 is the piercing crotch according to claim 1, wherein the rod portion has the rotary gripping portion at least at two positions on the front end side and the rear end side. And

  Since the user normally holds the rod part with both hands, it is appropriate to provide the rotary grip part at two places on the rod part. Specifically, it is desirable to provide the rotary gripping portions adjacent to the front end side of the non-rotating gripping portion, one each near the front end and near the rear end of the rod portion. In this way, when changing the rod part, the user can change the holding part by simply sliding his / her hand on the surface of the rod part from the non-rotating holding part to the rotating holding part or vice versa with the holding interval of both hands as it is. It is possible to respond instantaneously to changes in the situation. Although it is possible to provide more than 3 non-rotating gripping parts, there is no room for the user to change the rod part while looking at his hand during violent suppression. To prevent erroneous operation, there are two rotating gripping parts. It is appropriate to do.

  Next, the invention described in claim 3 is the piercing crotch according to claim 1 or 2, wherein the rod portion includes an outer tube having the rotary gripping portion and an inner tube to which an arm portion is attached at the tip. The length of the rod part can be expanded and contracted by pulling the inner cylinder out of the outer cylinder and fixing it.

  By making the entire length of the rod part extendable, the distance between the arm part and the gripping part can be changed as appropriate, so that the arm part protrudes from outside the attackable range against a gangster holding a weapon such as a knife, for example. Can do. On the other hand, in the suppression action in a narrow space, the rod part can be used in a short and easy-to-handle state without extending. In addition, it is desirable to provide a fixing mechanism between the inner cylinder and the outer cylinder that can be locked in any state when the rod portion is extended or shortened to prevent inadvertent expansion and contraction of the rod portion during the pressure-suppressing action.

The stabbed crotch according to the present invention reduces the resistance of thieves by instantly changing the rod part from the non-rotating gripping part to the rotating gripping part even when the arm part is gripped and twisted by a thief subject to suppression. ,
Demonstrates the effect of preventing piercing from being taken up by thugs. Further, the stabbed crotch according to the present invention has an extremely simple structure, is lightweight, robust, and can be manufactured at a low cost. Therefore, it is excellent in handling the suppression action on the spot, has high durability, and is practical. Therefore, it can be easily used not only by police officers and security officers but also by general users who have not received advanced training, and is also suitable for widespread deployment to schools and public facilities at relatively low prices. Yes.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view photograph of a prototype showing an example of an embodiment of piercing according to the present invention. Stitching consists of a rod part 1 and an arm part 2 attached to the tip thereof. The arm portion 2 includes a substantially U-shaped main arm 20 and a substantially U-shaped auxiliary arm 21 fixed to one end of the main arm 20 in the opposite direction. The auxiliary arm 21 is a member for aiming to fall by applying a so-called “foot wiping” by hooking on a leg of a thug and pulling a piercing crotch. From the viewpoint of placing importance on lightness, it is preferable that the main members of the rod portion 1 and the arm portion 2 are made of light metal, particularly aluminum.

The rod portion 1 accommodates the first inner cylinder 11 and the second inner cylinder 12 in a nested manner in the rod outer cylinder 10 so that the entire length can be expanded and contracted. The rod outer cylinder 10 is provided with fixed grips 14 near the front end and at the rear end, which are formed by, for example, attaching a rubber non-slip grip member around the entire surface of the rod outer cylinder 10. . Further, the rotary grip 15 is fitted adjacent to the front side of the two fixed grips 14. The rotary grip 15 is a hard synthetic resin cylinder or a rubber non-slip grip member attached thereto, and is freely rotatable with respect to the rod outer cylinder 10.

In the case of a right-handed user, the left hand holds the fixed grip 14 near the front end and the right hand holds the fixed grip 14 at the rear end, and holds the piercing crotch on the right side of his / her body. And, when a thief tries to escape or counterattack by grasping and twisting the arm part 2 during the suppression action, and the user is likely to take away the piercing crest without resisting the force, the user immediately takes one hand or What is necessary is just to slide both hands and to carry to the rotation holding part 15. As a result, even if a thief twists the arm portion 2 and the rod outer cylinder 10 rotates, the rotational force is not directly transmitted to the rotary gripping portion 15, and the piercing is removed from the user's hand. This is prevented. In the state where the arm portion 2 holds the arm portion 2, both hands are blocked, so that it is not possible to actively resist the user. The user can pull the pierced crotch when the thief releases his hand for escape or counterattack, and change the posture to the fixed gripping part 14 to resume the suppression action.

  2 is an enlarged photograph of the front end portion of the rod portion 1 shown as A in FIG. 1, and FIG. 3 is an enlarged photograph of the rear end portion of the rod portion 1 also shown as B. In any part of AB, a rotary grip 15 is provided adjacent to the front side of the fixed grip 14 and the outer diameters of both grips are the same, so the user can instantly slide the hand. The holding part can be changed. Further, in the present embodiment, the surface of the fixed gripping portion 14 is subjected to anti-slip processing, and the user can distinguish between the fixed gripping portion 14 and the rotary gripping portion 15 by touching the hand, so that even during the suppression action, it is at hand. It is possible to switch accurately without losing eyes.

  FIG. 4 is a side view showing a state in which the entire length of the rod portion 1 of the prototype is extended. By sequentially pulling out and fixing the first inner cylinder 11 and the second inner cylinder 12 accommodated in a nested manner inside the rod outer cylinder 10, the total length of the rod portion 1 can be extended by about 2 times or about 3 times. As a result, for example, a thug with a weapon such as a blade can be controlled from outside the effective range of the weapon, and the safety of the user can be improved. In the prototype of this embodiment, the total length of the first and second inner cylinders is slightly shorter than that of the rod outer cylinder 10 and can be stored therein.

  FIG. 5 is an enlarged photograph of the fixing portion of the second inner cylinder 12 shown as C in FIG. 4, and FIG. 6 is an enlarged photograph of the fixing portion of the first inner cylinder 11 also shown as D. The CD fixing structure is common, and in this embodiment, a fixing ball 16 having a spring mechanism (not shown) is provided near the front end of the rod outer cylinder 10 and the first inner cylinder 11, and the first inner cylinder 11. A fixing hole 17 is provided on each of the outer surfaces near the rear end of the second inner cylinder 12. When the rod portion 1 is extended, when the inner cylinder is pulled out and the fixed ball 16 matches the fixed hole 17, the fixed ball 16 is fitted into the fixed hole 17 by the repulsive force of the spring mechanism, and the inner cylinder is fixed. When the rod portion 1 is shortened, the fixing ball 16 can be manually pushed in to release the fixing, and the inner cylinder can be stored.

  In the present embodiment, the rod portion 1 has a three-stage structure including the first second inner cylinder, but the piercing according to the present invention may have a two-stage structure including only the first inner cylinder. However, a structure without an expansion / contraction mechanism may be used.

  As mentioned above, although embodiment of this invention was described referring drawings, this invention is not necessarily limited only to the structure mentioned above, In the range which achieves the objective of this invention and has an effect, suitably As long as they can be modified and fall within the scope of the technical idea of the present invention, they belong to the technical scope of the present invention.

The stabbed crotch according to the present invention can be used as a security equipment for police officers and security officers, and it is effective if a person who has not received advanced training, such as a staff member of a school or public facility, receives a prescribed course. It can be used and can be spread as a simple and low-cost security device.
