Description

The present invention relates to a protective shield with a discharge function, which is used to protect oneself from thugs and the like and is equipped with a discharge function similar to that of a stun gun.

2. Description of the Related Art Conventionally, stun guns have been sold as self-defense equipment for protecting oneself from robbers, thugs (intruders), and the like, which give electric shocks (electrical shocks) with high voltage to the opponents to stop them from moving. The stun gun mainly includes a portable handy type and a police baton type, but various other types of stun guns have been proposed.
For example, Patent Literature 1 discloses a shield provided with a stun gun attached to a pair of strip electrodes for discharge on the front side of the shield body.
In the shield equipped with the stun gun of Patent Document 1, a high voltage is applied to a pair of strip-shaped electrodes arranged in parallel with a gap on the surface of the shield body to generate an electric discharge, thereby intimidating the opponent. If necessary, the user can be protected by pressing the surface of the shield body (strip electrode) against the opponent's body to give an electric shock.

Here, it is generally known that the smaller the gap between the electrodes (the shorter the distance), the larger (easily generated) the discharge between the pair of electrodes. In the case of the strip electrodes as in Patent Document 1, if the gaps (distances) between the electrodes differ depending on the location, the discharge will be concentrated in the places where the gaps between the electrodes are narrow (short distances), sufficiently intimidating the other party. Therefore, it is necessary to arrange the electrodes so that the gap (distance) between the electrodes is constant (uniform) over the entire length of the strip electrodes.
However, in order to reliably protect the user's body, the size of the shield body is increased, and the strip electrodes arranged along the outer circumference of the surface of the shield body are also elongated. As a result, the positional deviation and inclination (oblique movement) of the electrodes have a greater effect on the bias of the discharge, making it easier for the discharge to be concentrated (partially) on a part of the electrode, so that the entire electrode can be effectively used. There was a problem that it was not possible to

The shape, number, arrangement, and fixing method to the shield plate portion are not limited to the present embodiment, and are appropriately selected. Hard rubber or synthetic resin is preferably used as the material of the support member, but a composite material in which the outer surface of a metal plate such as stainless steel is covered with rubber or synthetic resin may also be used.

The grip portion 15 is formed in a cylindrical shape from a synthetic resin such as ABS having insulating properties and strength, and a high voltage generating circuit can be built in the hollow portion. A battery (not shown) that serves as a power source for the high voltage generating circuit is also built into the hollow portion of the handle portion 15 . As shown in FIG. 1, the handle portion 15 is provided with an operating switch 20 for the high voltage generating circuit. When the user presses the operating switch 20, the high voltage generating circuit generates a high voltage. can be made In this embodiment, the operation switch 20 is attached to the shield plate portion 11 side of the handle portion 15, but the position of the operation switch 20 is appropriately selected.
The high voltage generating circuit is connected to a pair of output terminals (not shown) inside the terminal box 16 via cables (lead wires) 22. As shown in FIG. Two mounting screws 23 passing through the strip electrodes 12 and 13 and the shield plate portion 11 are screwed to the respective output terminals, thereby electrically connecting the output terminals and the strip electrodes 12 and 13, and connecting the terminals together. A box 16 is fixed to the shield plate portion 11 .

The strip-shaped discharge electrodes 12 and 13 are arranged with a predetermined gap (for example, about 7 to 12 mm), and a discharge can be generated by applying a high voltage.
