Description

      In the case where a handgun is stolen mainly by a police officer or other law enforcement agency, the present invention has a gun gun as a police officer (hereinafter referred to as “other law enforcement officer”) It is a target tracking type automatic safety device which is made to be able to fire when it is directed to the robber if it is directed to the robber without being fired even if the trigger is pulled. In addition, when the police officer of the party is attacked by surprise or is otherwise unable to recapture the gun and the lanyard is cut off and robbed, the gun is already incapacitated, forcing the trigger and the hammer into force. It is also a self-destructing device that, if actuated, can damage other internal parts of the gun body and can not be easily repaired.

In conventional rotary loan guns of government loan guns, no manually operated safety device is provided. Although there is a locking type in some cases, at any time during storage, it is not practical because it takes time to release it in emergency situations when carrying it during work, and the risk of the police officer who is the possessing manager is rather increased. I will. In addition, in the case of battery maintenance management problems and fighting, there is a risk of damage, inactivation, or malfunction when electronic engineering devices are used, and their reliability as a device that commits life is low.

  Although the current rotating magazine type handgun is equipped with a safety device to prevent the explosion during the opening and closing operation of the magazine or falling of the gun, it also identifies the shooter to shoot and the shooter to be shot and identifies the muzzle direction, There is no safety device to judge whether or not to shoot. Therefore, if a police officer in public service is robbed of a loan gun and fire damage is caused to the person and an unrelated general citizen etc., there is a high possibility that the public management operation responsibility of the gun will be pursued, and the compensation amount There is also concern that it will be expensive. In addition, since this case is difficult to predict the occurrence and often accompanied by a large impact when fighting, the burden on the maintenance of the battery and delicate electronic circuits is large in the electronic device, and it should be an emergency. Reliable operation is difficult. Therefore, it is necessary to take measures in consideration of robust operation and cost, human engineering, and psychological reaction.

  The lanyard ring fixed shaft was extended inside the grip, and an eccentric cylindrical horizontal rotation cam was placed on the top of the lanyard ring fixed shaft and fixed by a set screw. A vertical fan-shaped vertical rotating cam having a partial slit in the outer peripheral portion and having a protrusion below the rotating shaft is placed over and held by the grip screw portion in the grip, and the spring is set so as to continuously rotate backward.

The gun itself is equipped with an automatic safety device that automatically identifies the target and shooter position information according to the direction of the lanyard, and manages the muzzle and limits the firing. In addition, the installation of this device only involves replacing the lanyard ring with a special one and incorporating several sturdy small parts into the empty space in the grip, without requiring any modification or processing of the gun body. Therefore, many advantages are expected in the installation and operation of existing handguns.
In addition to the purpose of failing to steal a loan gun by a thug by the present invention, the present invention makes it possible to force aggressive shooting against a gun that is automatically incapacitated even if it is robbed. Operation can lead to damage or deformation locking of the critical trigger parts, and can also prevent secondary and tertiary damage to third parties. In addition, since operations that do not involve the regular shooting posture do not trigger, it is possible to exert a preventing effect against a violent explosion other than the target to be shot in the shooting training.
When a regular shooter (police officer) shoots at a target person (thoussman) or target to be shot and shoots correctly, take a regular shooting position, aim accurately with both hands, and have a hammer and trigger without shaking. If you do, the original shooting purpose will be reached.

The following description of the drawings will be made as a drawing when the device of the present invention is incorporated into a Japanese working police handgun. (However, parts not directly related to the strike are not shown. The same applies to the following.)
It is a side view when a trigger can be pulled (double action) in the state which the alignment of the predetermined coordinate of this invention, or muzzle direction corresponded, and the automatic safety device was cancelled | released and it became possible to fire. FIG. 8 is a side view of the automatic safety device working to make the non-triggerable state when the arrangement of the predetermined coordinates of the present invention and the muzzle direction do not match. It is a side view when a hammer is raised (single action) in the state which the sequence of the predetermined coordinates of this invention and muzzle direction corresponded, and the automatic safety device was cancelled | released and it became possible to fire.

  In order to form three-point coordinates for grasping position information, the present invention sets coordinates as follows for the shooter, handgun and target. The first coordinate is the root of the lanyard connected to the bandage of the shooter, the second coordinate is the handgun, and the third coordinate is the target itself. There are parts in the grip of the handgun for making it possible to recognize the sequence of coordinates and to decide whether or not to shoot. A lanyard ring fixed shaft (hereinafter referred to as a ring fixed shaft) was extended as needed into the grip, and the cylinder to be covered at the tip was notched around the front surface and left and right sides, and an eccentric cylindrical component was prepared. This was put on the top of the extended ring fixed shaft, and fixed from behind with a set screw. At this time, a part of the rear of the ring shaft is cut in a semicylindrical shape so that the setscrews can align and fix the respective coordinates in a straight line. Since the ring fixed shaft is rotatable so as to follow even if it is originally pulled by the lanyard, the one in which the eccentric cylindrical part is put on the ring shaft is used as the horizontal rotating cam and its vertical shaft. The corresponding vertical rotation cam uses the fixed screw of the grip panel as the horizontal axis of vertical rotation. The shape of the vertical rotation cam block is a fan-like shape that starts to open as viewed from the side, and a partial slit is provided on the outer peripheral portion thereof and has a beak-like projection below the rotation shaft. When the deformation fan-shaped vertical rotation cam block is vertically rotated with the horizontal axis as a fulcrum, the above-mentioned beak-like projection part enters on the track of the horizontal rotation cam, and the whole rolls forward and backward by its entry and exit. It is arranged like. The vertical rotation cam is constantly trying to rotate backward (in the intrusion direction) by the spring

Hereinafter, the incorporation of the device and the role of each part will be described with reference to the attached drawings. In order to implement the present invention, the device of the present invention is incorporated into a working police pistol. First, remove the grip screw, remove one side of the grip panel 8 (left side as viewed from the rear) and the existing lanyard ring, reassemble into the 1st invention lanyard ring, 3 horizontal cam sets, and the remaining one side Attach the 5 vertical rotation cam blocks to the pipe-like plastic shaft for screw penetration of the grip panel, hook its return spring 6 into the hole provided on the cam and the inside of the gun frame's grip frame, and the vertical rotation cam constantly Set to try to rotate backwards. Reinstall the grip panel 8. Once the above parts have been reassembled and assembled, the rest is the same as conventional daily equipment installation.
The metal fitting at the tip of the predetermined lanyard is attached to the lanyard ring, the other is attached to the predetermined position of the waist strap, and the handgun is stored in the holster. In this state, the gravity on the lanyard already causes the lanyard ring to hang on the grip side of the gun housed in the holster, or to the front of the grip, thereby maintaining a non-fireable state. Therefore, the hand-held gun is constantly in a safe state, and only the police officer who is the owner-manager can fire the opponent to shoot only when the regular shooting posture is set with the intention of firing.
Hereinafter, with reference to the attached drawings, a description will be given of whether or not the shocking is caused by the movement of the parts of the apparatus, and the arrangement of coordinates for grasping the position information.
FIG. 1 shows the shape and mutual operation of the parts constituting the present invention, and the working position of the parts at this time indicates that the vertical rotation cam block pushes up the projection portion by the rotation of the horizontal cam and shows a possible state of forward rotation. . The muzzle direction at this time is on the right.
Since the lanyard ring of the component of this invention changed the direction from the rear to the side in FIG. 2, the stop position of the horizontal rotation cam changes, the vertical rotation cam block rotates backward, and the lower projection portion is downward. Sinking to the lower part of the gun indicates that the activation of the existing percussion device inside the gun is to be brought from the possibilistic state to the non-strike state. Likewise, the muzzle direction remains right.
Fig. 3-1 shows the inside of the entire gun when the device of the present invention is incorporated into the gun and in the state capable of firing. At this time, the lanyard ring is pulled backward, and the vertical rotation cam block is in the forward rotation state, and the slit of the outer peripheral portion is directed to a position where the hammer strut can be lowered.
Fig. 3-2 shows a state in which the lanyard ring can not be pulled backward, and is directed laterally to the gun without being pulled backward. Therefore, while the vertical rotation cam block is in a backward rotation state, the slits in the outer peripheral portion are directed to a position that prevents the descent of the hammer strut.
Fig. 3-3 shows a state in which a single action firing is performed when the shooting is possible.
A in Fig. 4 is a police officer (coordinate 1), B is a handgun when aiming a thug in a regular shooting position (coordinate 2), C is a thug that tries to execute robbery (coordinate 3), and all Both the alignment of the coordinates of and the muzzle direction are correctly aligned and can be fired.
Fig. 5 is a layout view seen from the top right of the arrangement of the coordinates and the muzzle direction of the situation of the drawing 4 in Fig. 6, but the order of the coordinates has not changed, but the muzzle direction is directed to the police officer during fighting. It is in a state where it is impossible to launch it.
FIG. 7 also shows that the muzzle direction can not be shot off because the muzzle direction is directed to the side including the danger of flow bullet during fighting.
Fig. 8 shows a state in which the police officer can retake the handgun and shoot at the side of the criminal again.
FIG. 9 shows the state of a police officer shooting a target D in a regular shooting posture during shooting training.
In FIG. 10, while firing at a position next to it, without taking the regular shooting posture, with the direction of the muzzle directed to a direction other than the target, it is not possible to fire as the trigger is pulled.

  In addition to preventing the robbery of a government loan gun during public service, it is also possible to prevent an explosion at the time of shooting training, an explosion at the time of carrying, or returning to a gunhouse. In addition, it helps to prevent non-target shooting fires at shooting ranges outside of Japan.

Claims (3)

    Attach the horizontal rotation cam to the inside of the grip by attaching the lanyard ring attachment rotary shaft attached to the grip bottom of the revolver (rotary magazine type handgun), attach the horizontal rotary cam, and adjust the gun internal A structure that prevents the descent of the hammer strut of the existing in-vitro equipment, making it impossible to explode.     Normally, even if the lanyard ring mounting rotation shaft in claim 1 rotates and the horizontal rotation cam rotates horizontally, the falling of the hammer strut is prevented without rotating the vertical rotation cam block except at a predetermined rotation stop position. However, only by a predetermined rotation stop position, the vertical rotation cam block vertically rotates by a predetermined angle, allowing the descent of the hammer strut to make the explosion possible.     Although the gun is divided into the non-fireable state and the fire-ready state according to the rotational stop position of each lanyard ring shaft in claim 1 and claim 2, usually the fire is generated using the gravity of the spring in the grip and the lanyard itself outside the grip. Structure that can be automatically reset to the disabled position constantly.
