Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for quickly arresting a robber who attacks a financial institution and the like, and also relates to a device for preventing such a crime.

[0002]

2. Description of the Related Art In recent years, there have been many cases of robbery attacks on financial institutions such as banks and convenience stores operating late at night. In this type of case, it is not easy to investigate the criminal because there is no causal relationship between the criminal act and the victim, and thus the period often remains unsolved. Hidden cameras are installed at financial institutions, and the body and back of the criminal can be guessed to some extent, but it is not easy to identify because the criminal generally hides his face.

Conventionally, in order to facilitate the pursuit and investigation of a robbery of this kind, a method of throwing a ball containing a special liquid to the criminal to rupture it and attaching the filled liquid is used in some cases. . However, since the thief has been agitated and has lost his composure, he cannot throw the ball accurately, and therefore the probability of hitting the criminal is very low. In addition, things like balls are often useless because they do not know their storage location in an emergency.

Further, there is known a device for temporarily restraining a criminal who is about to escape from a financial institution or the like and automatically pouring a special liquid as a mark at that time. The crime prevention device installs a paint spraying device near the door and sprays the liquid from the device.At this time, when the criminal opens the door, the installed sensor detects the criminal. By applying a brake to the door and controlling the opening operation to take time, the liquid is surely attached to the criminal. However, such a device requires an electromagnetic brake for making the opening of the door heavy and a control device for operating the brake, and a paint spraying device must be installed at the doorway of the door. There are many points that are not possible in small stores.

Therefore, the applicant has filed a patent application for "security device" as of December 31, 1993. This security device is a digestive organ or something similar to the digestive organ, and has a main body container filled with the above-mentioned special liquid and compression air, and a tube is extended from the main body container and a spray type nozzle or direct type is provided at its tip. It is characterized in that nozzles are provided and the special liquid is ejected from these nozzles. Although a fire extinguisher is used as a means for injecting the above-mentioned special liquid, there are problems that the structure is complicated, the manufacturing cost is high, and the reliability with respect to instantaneous operation is low.

[0006]

As described above, it is not easy to find and arrest a robbery person, it is not reliable to use a conventional ball, and the conventional crime prevention device is expensive to install and expensive to manufacture. There are many problems such as high cost. The problems to be solved by the present invention are these problems, and a device for quickly arresting a robbery person, which is inexpensive in manufacturing cost and reliable in an instant operation, and a device for use in the device Provide special liquid to do.

[0007]

The security device of the present invention applies a special liquid to a robbery. This point is common to the method using a ball or the like, but the present invention has high probability. Is a technique for attaching. This device has a structure in which the special liquid is filled in a cylinder, and the liquid is ejected from a nozzle provided at the tip of the cylinder as the piston moves. The piston can slide in the cylinder, and the spring force of a spring built in the cylinder is biased to the piston. The piston is equipped with a lock device and is always stopped at the retracted position.However, when the lock device is released, the piston moves forward to eject the special liquid in the cylinder from the nozzle. There is. There are two types of injection methods, part 1
One is a method of spraying in a mist with a spray-type nozzle, and the other is a method of spraying in a rod shape using a direct nozzle. Of course, the use place is different between the case of mist injection and the case of direct injection.

In the case of the above-mentioned mist injection, since the injection area is wide, it is installed at the entrance and exit, and in the case of direct injection, the injection is aimed at the robbery person, and therefore it is provided in front of the counter or the like. To be By the way, the special liquid to be sprayed must adhere to the criminal to exert the effect of being able to immediately arrest the criminal. Of course, the specific type is not limited, but it is a condition that it is an eye-catching color such as red or yellow and that it cannot be easily washed off. In addition, it is necessary to include a fluorescent paint so that it can be identified even at night and to give off a foul odor as an incidental condition. Further, the security device is provided with a siren that sounds when the device is activated.

[0009]

In the present invention, the special liquid is filled in the cylinder, and the special liquid is ejected by being pushed out from the tip nozzle by the piston sliding on the cylinder. Moreover, the injection is not an instantaneous injection but an injection that continues for a certain period of time. Therefore, the ejected liquid surely adheres to the robbery without requiring any special sensor or control device. The criminal to which the liquid adheres will escape in that state, but the red or yellow liquid will be spotted and immediately found. Also, if it smells bad, even if you change to another clothes to hide the adhering liquid, the smell that has soaked in your body can be identified, and if you use a police dog, immediately follow up on the criminal. Can be done. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the injection type security device according to the present invention. In the apparatus shown in the figure, the basic structure of the main body 1 is a cylinder, and the cylinder is filled with a special liquid.
Reference numeral 2 denotes a nozzle. A hose 3 is connected to the tip of the main body 1 and the nozzle 2 is attached to the tip of the hose. A piston, which is slidable, is built in the cylinder that serves as the main body 1. When the piston moves, the special liquid in the cylinder flows through the hose 3 and is jetted from the nozzle 2.

Reference numeral 4 indicates a starting lever, and 5 indicates a starting wire. When the starting lever 4 is pulled, the piston of the main body 1 is operated via the starting wire 5. That is, the piston in the cylinder of the main body is stopped at the retracted position by the lock device, but the lock device is released by the operation of the starting lever 4, and the piston moves forward. Then, the special liquid in the cylinder is jetted from the nozzle 2. Reference numeral 6 in the figure is a siren, which operates the starter lever 4 to eject the special liquid from the nozzle and simultaneously the siren sounds.

FIG. 2 shows a sectional view of the cylinder body 1. A piston 8 is slidable in the cylinder 7, a rod 9 extends rearwardly, and a coil spring 10 is attached between the rod 9 and the inner peripheral surface of the cylinder 7. A stopper 11 is fixed to the end of the rod 9, and claws 13, 13 are fitted in a groove 12 formed in the stopper 11. The stopper 11 is locked at a fixed position by the claw 13, and the piston 8 is also stopped.

The spring force of the coil spring 10 acts on the piston 8, and if the pawl 13 is opened and released, the piston 8 advances by the spring force. Since the cavity 14 of the cylinder 7 is filled with the special liquid, the piston 8 advances to eject the special liquid from the nozzle 2. By the way, the release of the claw 13 is carried out by pulling the starting lever 4, but if the starting lever 4 is pulled, the starting wire 5 moves the slider 15 to move the wedge 16 formed on the slider 15. It is performed by pushing out both the claws 13 and 13. Here, the claw 13 is pivotally supported so as to be swingable about a shaft 17.

When the pawl is released and the piston 8 advances, the stopper 11 enters the inside of the cylinder 7. Although the point of the limit switch 18 is in contact with the end surface of the stopper 11, the stopper 11 moves away from the point, and as a result, the siren is controlled to ring. Of course, the present invention does not limit the structure of the locking device for fixing the piston 8.

The injection-type crime prevention device shown in FIG. 2 is of a type installed at an entrance / exit, but there is also a hand type which is held by a hand and directly injects a robbery person, and FIG. 3 shows this embodiment.
The basic structure is the same as the installation type, but the locking device for locking and placing the piston is different. A rod 20 extends to the piston 19, and a stopper 21 is also fixed to the end of the rod. Then, the claw 23 is fitted in the groove 22 formed in the stopper 21.

The claw 23 is pivotally supported by a shaft 24 and can swing, and engages and disengages with the groove 22 of the stopper 21. The screw 26 is screwed. Therefore, when the cap 25 is rotated, the screw 26 moves to lift the other end of the claw 23, and the claw 23 is disengaged from the groove 22 of the stopper 21. When the claw 23 is released, the piston 19 advances due to the action of the spring force of the coil spring, and ejects the special liquid in the cylinder from the nozzle.

By the way, it is necessary that the special liquid used in these injection type security devices has a noticeable color such as yellow or red, is hard to remove, and gives off a bad odor. As a specific example of the special liquid satisfying these conditions, those composed of the components shown in Table 1 can be used. Among these ingredients, Marvozol TS-200, SF-1017, A / FT
SA-780 is a difficult-to-clean dye and isovaleric acid smells like apples and can be discerned by dogs even in small amounts. As described above, the crime prevention device according to the present invention sprays the special liquid onto the robbery, and can obtain the following effects.

[0018]

If the security device of the present invention is installed in a financial institution, a convenience store or the like, an intruding robbery can be quickly arrested. That is, it is possible to spray a special liquid by simply operating the device to a robber who robs the robber of robbing money and the like, and the liquid such as red or yellow is very useful in tracking and investigating the escape criminal. It is convenient. If the liquid has a bad odor, it is possible to investigate it with the help of a police dog. In addition, there are cases where the robbery to whom the liquid adheres is found not only by the investigator but also by the general public and is arrested by telephone call, which is very effective in arresting the robbery.

On the other hand, the security device does not require a sensor or a control device, and is constructed so that the liquid is ejected from the nozzle by the operation of the piston by the spring force. The structure is simple and the cost is low. It is very cheap, easy to install, and can be attached to a criminal in order to spray liquid continuously for a certain period of time. Further, by publicizing that the device is installed, a robbery crime can be prevented in advance.
