Description
The present invention relates to a weapon and more particularly to
a device with which a policeman may subdue a criminal.
At the present time the methods of placing a violent criminal or an
insane person under arrest may lead to his own injury, or the
injury of the police or of innocent persons. If the police use
their guns, the criminal may be killed or innocent bystanders shot.
If the police attempt to sue their clubs, they may be injured while
they are grappling with the burglar. It has been desired to provide
a hand-carried arrest device which is to replace clubs.
It is the objective of the present invention to provide a device
for subduing criminals without killing or permanently injuring
them.
It is a further objective of the present invention to provide a
baton-type arrest device with which a criminal may be rendered
helpless temporarily.
This invention is based upon the discovery of a phenomenon that a
minute electric current applied to two needle electrodes which are
pierced under the skin of the human body at a slight interval
generates a great electric shock which cannot be generated if the
same minute electric current is applied through the same needle
electrodes contacted upon the skin.
In accordance with the present invention, two electrode needles are
projected from a casing of a hand-carried device only when the
casing is pressed against the skin of the human body and are
pierced into the skin to come into contact with the subcutaneous
fat layer of the skin. The electrodes are connected to batteries.
The current is sufficient to stun the criminal to a temporary state
of false epilepsy, which renders him helpless. The shock is not
enough to kill or permanently injure the criminal.
Other features and objectives of the present invention will be
apparent from the following detailed description of a preferred
embodiment of the invention, taken in conjunction with the
accompanying drawings.
In the drawings:
FIGS. 1 to 3 illustrate a baton-type arresting device, the upper
half being sectioned and lower half being plan views;
FIG. 1 shows the position in which the electric shock needles
cannot be projected;
FIG. 2 shows the position in which the electric shock needles can
be projected;
FIG. 3 shows the position in which the electric shock needles are
projected .
The electrical resistance of the skin of the human body varies with
its dry or wet state and the size of the contact surface. However,
the range of the resistance inside the body is said to be about 150
to 500 ohms. The strength of the electrical shock is related to the
strength of the electric current passing through the human body so
that, even if the voltage is high and the current is weak, there
will be no danger. For example, in the case of an alternating
current of the commercial frequency (about 110 volts at 60 cycles),
a considerable pain will be felt with about 1 ma. of current, an
unbearable pain will be felt with about 10 ma., the muscle will
shrink so much as not to move with 20 ma., and a danger of electric
shock death will be caused with 50 ma. Such electric shocks upon
the skin of the human body have been already utilized for a special
therapy (so-called electric shock therapy) in the treatment of
psychosis. The present invention utilizes the electric shock effect
and flows an electric shock current through the human body. A pair
of needles which are slightly spaced are pushed into the lower part
of the subcutaneous fat layer (not the skin surface) in order to
cause a temporary false epilepsy. It was found that the minute
electric current applied to a pair of electrode needles pierced
under skin generates a great electric shock which cannot be
generated if the said electrode needles are contacted upon the skin
surface. Therefore, the device according to the present invention
will cause a temporary false epilepsy by a minute electric current
which is effective in rendering the criminal helpless and yet is
safe.
An arresting device of the invention is adapted to be used instead
of the conventional nightstick (baton). An electric shock current
generating device is contained in a container (battery) 10 which is
fitted in a thin long cylindrical hollow body 20. A pair of
electric shock needles 1 is fitted at one end surface of said
cylindrical body 20. The outer surface of the rear part of the
cylindrical body 20 has a male screw 21 to which are screwed an
adjusting ring 22 and a cap 23. The cap 23 has a pushbutton switch
33. The cap 23 also has an electric bulb 24 and its socket 25 is in
contact with the output terminal 11 of the electric shock current
generating device. A conducting plate 26 comes into contact with
the socket 25 when the pushbutton switch 33 is pushed. Plate 26 is
connected with a conducting plate 28 through conductive connector
27 at the inside wall of the cylindrical body 20 in its lengthwise
direction. A conducting plate 31 is secured to the end surface of
the side to which are fitted the electric shock needles 1. Plate 31
is electrically connected with the electric shock needles 1 through
a lead wire 32.
On the outer surface of the forward end of the cylindrical body 20
a protective cylinder 34 is fitted, having a pair of small holes 2,
opposite the electric shock needles 1. The protective cylinder 34
and the cylindrical body 20 are connected with each other through a
spring 36 fixed to them at their respective ends. In the position
shown in FIG. 1, in which the opposed end surfaces of the
protective cylinder 34 and adjusting ring 22 are in contact with
each other, the protective cylinder 34 cannot move rightward. But,
in such state in which the adjusting ring 22 has retreated as is
shown in FIG. 2, the protective cylinder 34 can retreat against the
force of the spring 36 into contact with the adjusting ring 22 so
that the electric shock needles 1 may correspondingly project out
of the small holes 2 (see FIG. 3). The projecting length of each
electric shock needle can be adjusted by the set position of the
adjusting ring 22. The position of the adjusting ring 22 is
determined by judging the thickness of the clothing worn by the
criminal. The inserted length of each electric shock needle may be
adjusted to the clothes of the criminal, whether the criminal wears
an overcoat in winter or only a shirt in summer. When the end
surface of the protective cylinder is pushed into contact with the
criminal, the protective cylinder 34 will retreat and the electric
shock needles 1 will be able to be pushed into the body of the
criminal through the clothing.
A spindle 35 within the protective cylinder 34 has pasted on its
surface a conducting plate 30. Plate 30 is in sliding contact with
the conducting plate 31 of the cylindrical body. A conducting plate
29 is in sliding contact with the conducting plate 28 of the
cylindrical body is fixed to the tip of said spindle. Therefore,
after or when the electric shock needles 1 are pushed into the body
of the criminal, if the pushbutton switch 33 is pushed, an electric
circuit is formed. The circuit includes the output terminal 11 of
the electric shock current generating device, electric bulb 24,
socket 25, conducting plate 26, connector 27, conducting plates 28
to 31, lead wire 32, electric shock needles 1 and the human body.
The criminal will receive the electric shock current and will
immediately lose his power to resist. When the cylindrical body 20
is pulled, due to the returning force of the spring 36, the
electric shock needles 1 will retreat and hide in the protective
cylinder 34 (FIG. 2). Further, when not in use, if the position
shown in FIG. 1 is kept, the electric shock needles will not
project and will be safe.
When the cylindrical body 20, protective cylinder 34, adjusting
ring 22 and cap 23 are molded of strong plastic, they will be able
to be made light and tough. The entire apparatus may be made so
small as to be adapted to be carried in a handbag of a lady for
self-protection. Further, in the illustrated embodiment, the
electric bulb 24 may be utilized, for example, for traffic
signaling at night and for communication by the flicker of the
bulb. But it has no direct connection with the present invention
and therefore shall not be detailed herein.
Though the present invention has been described with reference to
the particular embodiment of the arrest device, it can be adapted
for other electric shock generating devices, for example, for
causing beasts to attain a syncopic state.
