Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a portable piercing device that is combined with a guard provided in a police car or the like.

[0002]

[Prior art]

 In recent years, Japanese crime has tended to become more violent, and the police side, which is the side that captures criminals, is also required to devise ways. For example, even police officers who directly confront criminals are no longer able to deal with it by simply using conventional short batons or shields.

[0003]

[Problems to be solved by the device]

 That is, it is a short self-defense tool of about 40 to 50 cm as a baton carried by a police officer or the like. For this reason, when a violent criminal wields a long-blade weapon such as a Japanese sword or a knife for knives, it is often difficult to attack and defend even a police officer who has learned self-defense (arrest). Since it may be cut off, it leaves a problem in terms of safety, etc., and the view of occupation that is still dangerous can not be wiped out, and the development of a new simple arrest tool is desired at an early stage.

In Japan, as a tool (arsenal) for arresting criminals and violent people from old times such as the Edo era, U-shaped, V-shaped, etc., are attached to the tip of a long rod of 6 or more. There is known a so-called piercing tool, which is a tool for attaching an iron body pressing tool that is held and directly pressing the body pressing tool to a criminal person or the like remotely. However, due to its long construction, this type of piercing is not suitable as a portable type, and it has not been widely used as a catching tool that is always equipped in modern times.

In view of the above situation, the present invention has, for example, an assembly-type piercing structure capable of assembling a guard stick (oak stick having a length of 1288 mm × φ31 mm) and a body pressing tool that are always loaded in a police car on site. Then, it aims at providing the portable piercing problem which solves the said subject.

[0006]

[Means for Solving the Problems]

 According to the present invention, a mounting pipe part having a slit for holding in a longitudinal direction is provided on a base end mounting handle part of a piercing body having a curved pressing part for sandwiching at least a body torso at a tip, and both ends of the slit are provided. A tightening screw shaft, which is rotated by a tightening lever, is laterally screwed to the tightening piece arranged in the above to form a connecting mechanism, and a stopper works at the end of the tightening screw shaft by a predetermined rotation of the tightening screw shaft. A locking mechanism is provided, and a guard stick end having a predetermined length is fitted to the mounting pipe portion, and the mounting pipe portion is tightened by one-touch operation of the tightening lever to integrate the guard stick.

In this case, the lock mechanism includes a disc cam with an engaging cam groove provided at the end of the tightening screw shaft and a spring-mounted stopper shaft arranged on one side of the tightening screw.

As described above, the attachment pipe portion with the slit formed at the base end of the piercing body for connecting the publicly known security stick that is always loaded in the police car is laterally screwed into the fastening pieces at both ends of the slit. The slit width is narrowed by turning the tightening lever that is integrated with the tightening screw shaft, and the stick is fixed on the mounting pipe by tightening and fixing the stick and the piercing body. Simply insert the guard stick end into the mounting pipe of the piercing body, and in this state, simply rotate the tightening lever in the reverse direction, and due to the screw thread of the tightening screw shaft, The slit width is reduced and the guard is fixed to form a long rod.

At this time, the disk cam at the end of the tightening screw shaft that is integral with the tightening lever also rotates, and the stopper shaft that is constantly pressed by the spring on the one side of the tightening that slides on the outer periphery of the disk cam falls into the engaging cam groove. The lock works automatically. That is, since the guard and the piercing body are connected by a one-touch operation of the tightening lever to form a piercing body of a certain length, it is an arresting tool that can be quickly dealt with in an emergency.

When not in use, if the stopper lever, which is a reverse lock mechanism, is retracted against the spring and the clamp lever is returned to its original position, the slit tightening in the mounting pipe section will be loosened. The guard can be pulled out and can be stored separately.

[0011]

[Embodiment of the invention]

 Hereinafter, an embodiment of the portable piercing device of the present invention will be described with reference to the drawings.

FIG. 1 shows a split type portable piercing device mounted on a police car, where 1 is formed with a U-shaped curved pressing portion 2 made of a metal round bar that holds at least the body trunk at the tip. In the piercing body, a holding slit 3 having a gap a is appropriately cut out in the longitudinal direction in a pipe-shaped base end mounting handle portion 1a of the piercing body 1 to form a mounting pipe portion 4, and both end pipes of the slit 3 are formed. A pair of tightening pieces 5 are provided so as to face each other, and a screw hole 6 having a reverse female screw is formed in each of the pair of tightening pieces 5. The screw holes 6 and 6 are provided with a tightening lever 7 at the center. A connection mechanism 9 is constructed by screwing together a tightening screw shaft 8 having a turnbuckle type screw portion 8a, 8b formed by changing the left and right threads formed by attaching the base end. Further, a disc cam 11 having an engaging cam groove 10 on the outer periphery is provided at one end of the tightening screw shaft 8 and a U-shaped support frame portion laterally protrudingly provided on the one tightening piece 5. A resilient stopper shaft 13 having a spring 12 attached to the base end portion of the front and rear frames 5a is arranged, and the tip end portion 13a of the stopper shaft 13 protruding from the support frame portion 5a is formed into the disc. The lock mechanism 14 is configured to be constantly in sliding contact with the outer peripheral surface 11a of the cam 11. Reference numeral 15 is a guard rod such as a known oak rod or lauan rod which is currently mounted on a policer and has a support rod structure. Thus, the portable piercing member 16 has the above-mentioned overall structure. In the figure, 17 is a cover body for covering the lock mechanism 14, and 18 is a fixing screw for the cover body 17.

To explain this action, first, as the equipment of the portable piercing part 16, in normal times, the piercing body 1 and the guard stick 15 are separated, and for example, a trunk of a police car (not shown) or Deploy it in a police box. However, as the guard stick 15, a single guard stick 15 which is conventionally used normally may be diverted.

Here, in an emergency where a violent person (criminal) having a weapon or the like appears and it is difficult to approach and arrest, the portable piercing crotch 16 that is an assembly type is appropriately taken out, and the tip portion 15a of the guard 15 is pierced. A fixed amount is inserted into the attachment pipe portion 4 of the base end attachment handle portion 1a of the main body 1. In this case, since the mounting pipe portion 4 has the slit 3 in the longitudinal direction, it can be easily inserted even if the fitting with the guard 15 is slightly tight.

In this state, the tightening lever 7 of the connecting mechanism 9 lying on the front side, which is the base end attachment handle 1a side of the piercing body 1, is inverted and rotated to the front position, which is the guard stick 15 side. For example, since the laterally arranged tightening screw shaft 8 integrated with the tightening lever 7 rotates, the turnbuckle type screw feed is performed by the screw parts 8a and 8b of the opposite screw structure at both ends of the tightening screw shaft 8 to face each other. The tightening pieces 5 and 5 serving as the bearing members are pulled close to each other, the gap a of the slit 3 is narrowed, and the guard 15 is tightened. That is, the guard 15 is instantly fixed by a one-touch operation of simply reversing the tightening lever 7.

At this time, since the disc cam 11 of the lock mechanism 14 formed at one end of the tightening screw shaft 8 rotates in the same manner, the outer peripheral surface 11a of the disc cam 11 has a spring attached to the base end shaft portion. Since the stopper shaft 13 that is elastically slid on the side of the disc cam 11 at 12 and constantly slides is located, when the engaging cam groove 10 of the outer peripheral surface 11a of the disc cam 11 reaches the stopper shaft 13, The stopper shaft 13 automatically falls into the engaging cam groove 10 and is locked (see FIG. 4), so that the above-mentioned looseness of the slit tightening is not caused.

In this way, the long piercing body 16 in which the piercing body 1 and the guard stick 15 are integrally connected is grasped, and the curved pressing portion 2 of the piercing body 1 at the tip end is grasped by gripping the guard stick 15 at an appropriate position. Fight to the side. Here, the curved pressing portion 2 is pressed against the torso of the criminal A, for example, as shown in FIG. 7, or against the neck to restrict the movement of the criminal, or it is struck against the arm holding the weapon to hit the weapon. It is to be caught by performing a remote arrest attack such as dropping.

It should be noted that, since the division work of the piercing main body 1 and the guard stick 15 after use is not urgent, on the contrary to the above, first, the proximal end of the stopper shaft 13 which is the stopper mechanism 14 is manually pushed against the spring 12. If the tip portion 13a is removed from the engaging cam groove 10 of the disc cam 11, the tightening screw shaft 8 side becomes free, so that the tightening lever 7 is returned from the guard stick 15 side to the piercing body 1 side and inverted. Loosen the slit tightening. After that, the guard 15 may be removed from the proximal end attachment handle 1a of the piercing body 1.

By the way, if the dimensions of the portable pierce are shown, for example, a stick made of an oak is 1288 mm × φ 31 mm, and the body of the pierce is a light alloy round bar having a diameter of 14 mm, and a bending width (diameter) 400 mm × depth. A curved pressing portion having 230 mm and a light alloy pipe having a diameter of 27.2 mm and a length of 500 mm are welded at a base end mounting handle portion to have a length of 745 mm. The total length of connecting the guard and the piercing body is 1903 mm. However, the mounting pipe portion of the base end mounting handle is 31 mm in diameter and slightly thicker.

[0020]

[Effect of the invention]

 As described above, the portable piercing device of the present invention uses the piercing body having a curved pressing portion for sandwiching the body part of the criminal, and the stick that is always used for the mounting pipe portion with the slit formed on the base end mounting handle. Since it is a compact structure that can be easily connected and connected, it is most suitable for an arresting tool such as being mounted on a police car or a police box. In addition, this handling is done by simply inserting one end of the guard stick into the mounting pipe part of the base end mounting handle of the piercing main body and reversing and rotating the tightening lever on the mounting pipe part. It can be tightened tightly by tightening the slit in the butt section, and it can be used as a piercing to respond immediately in an emergency when a violent criminal is caught.

[0021] Furthermore, since the guard stick is connected and fixed to the piercing body, a kind of turnbuckle structure is used, in which the screw of the tightening screw shaft laterally screwed into each tightening piece on both sides of the slit end of the mounting pipe part is a reverse screw. The tightening screw shaft can be securely tightened with the minimum screw thread, and the operation for releasing the tightening can be simply performed by rotating the tightening screw shaft, which is the reverse of the above, and the wand is detachable.

In addition, the portable piercing device of the present invention has an easy-to-assemble and simple structure, so that it is easy to manufacture, and the guard stick serving as a support handle is a known stick that is commonly used conventionally. Therefore, from this point as well, it can be provided at a low cost, and has a practical effect such as a tool that can be widely spread.
