Description

  The present invention relates to a crime prevention system installed in a store such as a bank, a post office, a precious metal store, a convenience store or a cash transport vehicle.

  Banks, post offices, precious metal stores, convenience stores, etc. and cash transport vehicles can be dealt with by crimes aimed at cash robbery, such as surveillance by security cameras and the sound of emergency bells, as well as police and security companies. Reports have been made.

  However, such conventional methods are usually dealt with for the first time after the incident occurs (arrival of police officers and guards), and it has not always been said to prevent such crimes.

  In view of these problems, as a means for preventing crime prevention, for example, the applicant of the present application intimidates and dismisses a suspicious person who illegally enters or approaches a store or a cash transport vehicle for the purpose of crime. In addition, a crime prevention system for injecting a fire extinguishing agent (carbon dioxide, powder) and a tear spray to the suspicious person has been proposed (see Patent Document 1).

  When jetting a fire extinguisher and intimidating and moving away a suspicious person, it is preferable to use a fire extinguisher that has been widely used in homes, stores, etc. for constructing a crime prevention system at a relatively low cost. . Since such a fire extinguisher normally injects a fire extinguisher contained in a cylinder by lever operation, it is desirable to automatically perform this lever operation.

  As a method for automatically operating the lever of the fire extinguisher, for example, a method using a temperature-sensitive actuator (see Patent Document 2) or a shape memory alloy (see Patent Document 3) has been proposed.

  However, in these methods, it is difficult to stop the injection of the fire extinguishing agent once it has been activated, and it is also impossible to stop the injection after injecting for a certain period of time and then inject again. This is because all of these operate in principle when a fire extinguisher is installed at a high temperature due to the occurrence of a fire, and do not operate in other cases (room temperature). If these are to be operated at room temperature, a device for heating / cooling the temperature-sensitive actuator and the shape memory alloy is required, and costs are increased.

  When injecting a suspicious person by injecting a fire extinguisher from a fire extinguisher, the injection may be performed for a short time, or a short time injection may be repeated a plurality of times. For this purpose, such injection is possible. It is necessary to automatically operate the lever of such a fire extinguisher.

The object of the present invention is based on the above-mentioned problems, and is a crime prevention system capable of effectively intimidating and leaving a suspicious person who illegally enters or approaches a building or a vehicle and prevents the occurrence of a crime. Is to provide.

Because it becomes.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a configuration of an embodiment of a security system according to the present invention. The crime prevention system 10 includes a plurality of (three in the figure) lever-operated fire extinguishers 11 and the operation levers 12 of the respective fire extinguishers. It includes an actuator 14 for injecting fire extinguishing agent, a control device 15, a remote control switch 16, a speaker 17, an alarm lamp 18, and a television camera 19.

  The fire extinguisher 11 injects a fire extinguisher from the nozzle 13 by operating the lever 12, but in this system 10, the lever 12 is operated by the operation of the actuator 14. The actuator 14 is connected to the control device 15 by the cable 20 and performs a lever operation by a control signal from the control device 15.

  As the fire extinguisher 11, it is preferable to use a commercially available fire extinguisher widely used in houses, stores, offices, etc. from the viewpoint of reducing the cost of the system, and in particular, it can effectively threaten a suspicious person It is desirable to use a carbon dioxide fire extinguisher, a powder fire extinguisher, and a foam fire extinguisher.

  The control device 15 is connected to the remote operation switch 16 through a cable 21 by wire, and the operation of the remote operation switch 16 causes the control device 15 to control the actuator 14, the speaker 17, the alarm lamp 18, and the television camera 19. In the figure, the control device 15 and the remote control switch 16 are connected by the cable 21, but instead of this, communication may be performed wirelessly.

  The remote control switch 16 is usually installed at a location away from the installation location of the fire extinguisher 11, the speaker 17, the alarm lamp 18 and the TV camera 19, and is installed in a form carried by a security guard or fixed in a monitoring room. Any of the formats can be used.

  The speaker 17 is connected to the control device 15 by a cable 22 and emits an alarm sound according to the operation with the remote control switch 16. The alarm lamp 18 is also connected to the control device 15 with a cable 23, and lights or blinks according to the operation with the remote operation switch 16. Furthermore, the TV camera 19 is also connected to the control device 15 with a cable 24, and the inside of the installed room or vehicle is photographed. Note that the video imaged by the television camera 19 is displayed on a television screen (not shown), and can be recorded by video recording (not shown) as necessary.

  FIG. 2 shows the fire extinguisher 11 and the actuator 14 attached thereto in the security system 10 of FIG. As described above, the fire extinguisher 11 is a lever-operated type that has been widely used in homes and stores. The lever 12 includes a movable lever 12a and a fixed lever 12b. The movable lever 12a is moved around the shaft 12c in a direction indicated by a double arrow A in the figure by a shaft 12c and a spring (not shown). When the movable lever 12a is pushed downward (opening direction) in the figure, a valve (not shown) inside the fire extinguisher 11 is opened, and a fire extinguisher is injected from the nozzle 13. On the other hand, when the movable lever 12a is lifted upward (in the closing direction), the above-described valve is closed and the injection of the fire extinguishing agent is stopped.

  In the illustrated fire extinguisher 11, the lever 12 is operated by the actuator 14. The actuator 14 includes an actuator body 25 and a rod 26, and the rod 26 is moved up and down in a direction indicated by a double arrow B by a drive mechanism (described later) housed in the body 25. The actuator 14 is connected to a control device 15 (see FIG. 1) (not shown) via a cable 20, and a drive mechanism is operated by a control signal from the control device 15.

  A lever housing case 27 is attached to the tip of the rod 26. The lever housing case 27 has a box shape so as to accommodate the movable lever 12a of the fire extinguisher 11, and the case 27 can be swung in the direction indicated by the double arrow C by the shaft 28. Here, when the rod 26 of the actuator 14 is lowered, the movable lever 12a is pushed down as shown by a broken line in the figure, and when the rod 26 is raised, the movable lever 12a is pushed up. That is, the extinguishing agent is injected from the nozzle 13 of the fire extinguisher 11 and the injection is stopped by the operation of the actuator 14.

  The actuator 14 is attached to the fire extinguisher 11 by an attachment member 29. The attachment member 29 includes an actuator support 30 and a fixed band 31, and the actuator 14 is fixed to the fire extinguisher 11 by attaching the fixed band 31 to the outer periphery of the fire extinguisher 11. Further, the main body 25 of the actuator 14 is swung in a direction indicated by a double arrow D by a shaft 32 provided on the actuator support 30. This is to make the rod 26 extend and contract and the operation of the movable lever 12a associated therewith smoothly.

  FIG. 3 shows the internal structure of the actuator 14. A motor 33 and an inner cylinder 34 are accommodated in the actuator body 25, a rod 26 is accommodated in the inner cylinder 34, and a bush 35 is fitted between them. As illustrated, the rod 26 is hollow, and a screw shaft 36 is inserted therein. The lower end portion of the rod 26 is in contact with the screw bush 37. The screw shaft 36 is coupled to the rotating shaft 39 of the motor 33 through a coupling 38. Further, the screw bush 37 is made non-rotatable by a non-rotating screw 40. A screw thread 36a is formed on the surface of the screw shaft 36, and a screw thread 37a is formed on the inner surface of the screw bush 37, respectively, which are in mesh with each other. Further, an elongated groove 34a is formed in the inner cylinder 34 so that the rotation-preventing screw 40 can be moved along with the movement of the screw bush 37 as will be described later. The upper and lower limits of the screw bushing 37 are restricted by the bushing 35 and the lowering by the stopper 41, respectively.

  Next, the operation of the actuator 14 will be described. As the rotary shaft 39 of the motor 33 is rotated, the screw shaft 36 is rotated, whereby the screw bush 37 is raised or lowered. This is because the screw bushing 37 cannot be rotated by the non-rotating screw 40. As the screw bush 37 is raised, the rod 26 is pushed up to rise (indicated by a broken line in the drawing), and the rod 26 is lowered as the screw bush 37 is lowered. As shown in FIG. 2, the movable lever 12a of the operation lever 12 of the fire extinguisher 11 is operated by the raising / lowering of the rod 26, whereby the fire extinguisher is injected from the nozzle 13 of the fire extinguisher 11 or the injection is performed. Will stop.

  In order to raise / lower the rod 26, it is necessary to rotate the motor 33 forward / reversely according to this, and a control signal for that purpose is sent from the control device 15 through the cable 20. Here, assuming that the rod 26 is lowered in the forward direction and the case in which it is raised is the reverse direction, the rod 26 is lowered, the movable lever 12a of the operation lever 12 is pushed down, and the fire extinguisher is ejected from the nozzle 13 when the control is performed. The device 15 outputs a signal for causing the motor 33 to rotate forward. On the other hand, when the rod 26 is raised and the movable lever 12a is pushed up to stop the injection of the extinguishing agent, the control device 15 outputs a signal for reversing the motor 33. It should be noted that the normal / reverse activation of the motor 33 is performed by limit switches (not shown) provided in the vicinity of the bush 35 and the stopper 41, respectively.

  Therefore, the extinguishing agent can be injected from the fire extinguisher 11 for a certain period of time by outputting a signal for reversing the motor 33 after a certain period of time has passed since the signal for causing the motor 33 to rotate in the forward direction from the control device 15. . Further, by outputting a signal so that the forward / reverse operation of the motor 33 is repeated at regular time intervals, the fire extinguisher can be intermittently injected from the fire extinguisher 11 at regular time intervals.

  FIG. 4 shows an example in which a crime prevention system according to the present invention is provided in a cash transport vehicle.

  A fire extinguisher 53 is attached to the back side of the wall 52 of the cargo compartment 51 of the cash transport vehicle 50 so that the opening of the nozzle 54 injects a fire extinguishing agent from the rear wall 52 toward the cargo compartment 51. The fire extinguisher 53 is provided with an actuator 55 for lever operation. Further, an alarm lamp 56 and a speaker 57 are installed in the cargo compartment 51, and an external alarm lamp 58 is also installed on the vehicle body. The control device 59 is installed in the cab 60, and the guard 61 carries the remote control switch 62 (attached to the belt in the figure). Here, the remote control switch 62 and the control device 59 are of a type that performs signal transmission wirelessly.

  Needless to say, the presence of the nozzle 54 attached to the wall 52 is not determined by painting the wall 52 or the like. Furthermore, it is desirable to install a plurality of fire extinguishers 53.

  Next, the operation of the security system shown in FIG. 4 will be described.

  When a suspicious person enters the cargo compartment 51 of the cash transport vehicle 50, when the guard 61 operates the remote control switch 62 that is carried, the operation signal from the switch 62 is wirelessly transmitted to the control device 59. The Next, the actuator 55 is actuated by a signal from the control device 59, and the fire extinguisher in the fire extinguisher 53 is injected from the nozzle 54 into the cargo compartment 51. At the same time, an alarm sound is emitted from the speaker 57, and the alarm lamps 56 and 58 are lit or blinking.

  The injection of fire extinguishing agent (carbon dioxide, powder or foam) from the nozzle 54, the alarm sound from the speaker 57 and the lighting (or flashing) of the alarm lamps 56, 58 prevent the intruder from moving in the cargo compartment 51. In addition, the presence of an intruder is also notified around the cash transport vehicle 50, so that crime can be prevented in advance. Needless to say, a television camera may be further installed in the cargo compartment 51 so that an intruder can be photographed. Further, in addition to the external alarm lamp 58, a speaker for sounding an alarm sound may be provided. Further, a tear gas spray whose operation is also controlled by the control device 59 may be additionally provided in the cargo compartment 51.

  FIG. 5 shows an example in which the security system according to the present invention is provided in a store such as a convenience store.

  In the store 70, a fire extinguisher 74 that is operated by an actuator 73 is installed inside the cashier counter 71 and on the back side of the ceiling 72, and the nozzle 75 is attached so as to inject a fire extinguisher into the store from the opening of the nozzle 75, respectively. . An alarm lamp 76 and a video camera 77 are attached to the ceiling 72, and a speaker 79 is attached to the wall surface 79. A control device 81 and a remote control switch 82 are installed on the floor surface 80. Here, the remote operation switch 82 is of a foot switch type, and operates when the employee 83 operates the foot switch 84 with his / her foot. The remote operation switch 82 may be attached to the back side of the upper surface of the counter 71 or the like, and may be operated by the employee 83 by hand.

  Of course, it goes without saying that the nozzle 75, the control device 81, and the remote control switch 82 of the fire extinguisher 74 must be kept in sight only by employees.

  Next, the operation of the security system shown in FIG. 5 will be described.

  When an intruder for the purpose of cash robbery approaches the cashier counter 71, when the employee 83 steps on the foot switch 84 of the remote operation switch 82 with his / her foot, an operation signal from the remote operation switch 82 is transmitted to the control device 81. Is done. Next, the actuator 73 is activated by a signal from the control device 81, and the fire extinguisher in the fire extinguisher 74 is injected from the nozzle 75 toward the intruder in the store. At the same time, an alarm sound is emitted from the speaker 79, and the alarm lamp 76 is turned on or flashes.

  In this example as well, the intruder's actions in the store 70 are prevented by the injection of fire extinguishing agent from the nozzle 75, the alarm sound from the speaker 79 and the lighting (or flashing) of the alarm lamp 76, thereby preventing crime. Will be able to prevent. Needless to say, in parallel with these operations, the video camera 77 always captures the behavior of the intruder. In addition, it is desirable to report to the police or security company through the control device 81 or the remote control switch 82. Furthermore, also in this embodiment, a tear gas spray whose operation is controlled by the control device 81 may be additionally provided.

  In each of the above-described embodiments, the actuator that performs the lever operation of the fire extinguisher is a type that uses a rotary motor and a screw shaft to raise and lower the rod. Instead, the linear motor is directly connected to the rod. It is good also as attaching. Further, it goes without saying that a gas pressure driven actuator that operates by an electric signal can be used instead of these electric actuators. Furthermore, as an operation of the actuator, the lever operation may be performed by clamping the movable lever and the fixed lever.

  As described above, the crime prevention system according to the present invention threatens to retreat by injecting a fire extinguishing agent to a suspicious person, and uses a fire extinguisher of a type that injects a fire extinguishing agent by operating a lever. This lever operation is automatically performed by a remote operation from the control device. As a result, a system can be constructed at a relatively low cost, and a suspicious person can be immediately threatened and removed.

  Furthermore, the method of automatically operating a lever-operated fire extinguisher with an actuator used in this system can be used not only for crime prevention but also as an automatic fire extinguishing device for performing fire extinguishing work in the event of a fire. .
