Description

  The present invention relates to a photoluminescent agent for crime prevention for spraying a phosphorescent agent that serves as a landmark for a criminal when a criminal who has performed a robbery escapes from an exit of a facility and assisting the early arrest of the criminal .

  Conventionally, when a burglar gets into a convenience store or a financial institution, a hard-to-drop paint such as a fluorescent paint is attached to the burglar and then the burglar is tracked. One method of attaching this paint to a burglar is to use a color ball. When a color ball hits an object or a person, the ball bursts and the paint pops out from the inside.

  As another method, there is an injection device that injects paint toward a burglar by remote control. This spraying device sprays paint from a spraying port provided at the entrance / exit by remote control using a power switch or the like. An example of this method is disclosed in Patent Document 1.

  As shown in FIG. 1, it is assumed that there is a visitor counter 12 in a building 11 such as a bank. There is an entrance / exit 13 in a part of the building 11, and an automatic door 14 is provided there. In this case, the security spraying device SP is embedded in the wall 16 of the entrance space 15. When a criminal robs and escapes from the entrance 13, a store clerk operates a switch (not shown) to spray paint in the entrance space 15.

  In either case, the burglar is identified using the paint as a clue. There is a method using a fluorescent agent or a phosphorescent agent in order to make the adhesion of the paint easily noticeable when the criminal acts described above are performed at night. Suppose a part of the criminal's body is exposed to a phosphorescent agent and the criminal is detained. When excitation light including ultraviolet light is irradiated at this time, the phosphorescent agent is excited to leave afterglow, and adhesion of the paint can be easily confirmed even when the criminal is in the dark. Patent Document 2 discloses a security marking spray that can be used for such purposes.

  FIG. 2 is a perspective view in which a part of the security marking spray 20 capable of spraying the above-described marking paint is broken. The marking spray 20 includes a marking liquid 24 and a propellant 25 as a main body 21, a spray container 22 including these, a spray button 23, a nozzle 26, and a cap 27. The marking liquid contains a fluorescent or luminous component. When the cap 27 is removed and the ejection button 23 is pressed, the marking liquid 24 is ejected from the tip of the nozzle 26. Since the marking liquid 24 has fluorescence or phosphorescence, the marking liquid itself emits light and can be recognized even in the dark when irradiated with ultraviolet rays or the like.

  Such a security marking spray 20 is small in size and exhibits its own spraying function, so that a person who is likely to become a victim can go out with him / her as a permanent item or for emergency use. .

  In the case of the above-described color ball, if the color ball is thrown from a distance to the robber, the accuracy rate is low, and the color ball does not necessarily hit the culprit. Even if the burglar is thrown and hit, if the distance between the clerk and the burglar is close, the clerk may be at risk. Even if hit, even if the color ball bursts out, it may not be clear whether the paint is attached to the clothes.

  In the case of the above-described injection device, even if the injection solution is a phosphorescent agent, the phosphorescent agent is not excited by ultraviolet rays or the like in advance, and therefore the phosphorescent agent does not emit light when the criminal goes out of the store in the dark. For this reason, it is difficult to identify the criminal and there is a high possibility that the criminal will be lost.

  Moreover, since the crime prevention spray device disclosed in Patent Document 1 is a device embedded in the entrance wall 16, the equipment cost including the interior of the building is high. Therefore, this injection device is not suitable for installation in an existing building, for example, a convenience store being opened.

  In the case of the crime prevention marking spray 20 described above, the victim must spray directly toward the criminal. When a burglar breaks into a convenience store or a financial institution, the clerk cannot always take out the security marking spray 20 immediately. Also, the clerk's awareness of crisis management varies, and even if criminal acts occur, the time until the clerk notices the crime varies depending on the situation. There are also various patterns of robbery and criminal acts. When a clerk notices a criminal act, the criminal often has already entered the escape system from the doorway. For this reason, even if the crime prevention marking spray 20 is taken out, the spray liquid does not reach the criminal location.

In any case, as long as normal paint is used, if the culprit is carried out at night and the criminal goes out of the store in the dark, it is difficult to confirm the adhesion of the paint and the criminal's appearance is difficult to see. , Often overlooked criminals.

  In order to solve this problem, the photoluminescent agent injection device for crime prevention of the present invention has an injection device main body installed in the vicinity of the escape route, and an aerosol containing a photoluminescent agent is applied to an injection target such as a criminal who is expected to escape. An anti-crime photoluminescent agent injection device for identifying or specifying an injection target by injecting and adhering, an injection cylinder filled with a photoluminescent agent solution for injection and a compressible gas, and the injection cylinder An injection lever that presses the nozzle portion, holds the injection cylinder in a standby position in the locked state, and releases the cylinder in order to guide the injection cylinder to the injection position when the locked state is released; and The cylinder is held in a standby state, and when an operation signal is given, an operation lock portion that releases the lock in the standby state, and the cylinder holder is held at a loading position for removing and inserting the injection cylinder.

  Here, the control circuit unit includes an operation switch that gives a start signal, and a human sensor that detects that the injection target has passed a specific location and generates a pass signal, and the start signal is received from the operation switch. After the input, the operation signal may be given to the operation lock unit only when a passage signal is input from the human sensor.

  Here, the actuator unit is a disk-like member fixed to the casing of the injection device main body, and a sliding surface having substantially the same radius of curvature is formed on the outer peripheral surface, and is cut into a part of the sliding surface. A cam provided with a notch, a hinge connecting lever having a cam follower that follows the sliding surface of the cam at the tip, and a spring that applies a pressure that causes the hinge connecting lever to follow the sliding surface of the cam. And when the cam follower enters the notch of the cam, the injection lever of the cylinder holder may be moved to the opening position.

  Here, the excitation light source may be an LED that emits at least ultraviolet light.

  Here, the injection cylinder may be a transparent container filled with a solution containing a phosphor and a compressed gas.

  Here, the injection cylinder may be configured such that the solution containing the phosphor is located below the container at the standby position, and the nozzle portion is directed downward at the injection position.

  According to the present invention, a liquid or foam-like phosphorescent agent is excited in advance, and when there is a burglary criminal act, the phosphorescent agent that has been phosphorescent can be attached to the criminal from an entrance of a store or the like. This makes it easier to track offenders at night. In addition, by connecting a human sensor to the injector and attaching this human sensor to the entrance, when the store clerk notices the burglary and operates the start switch of the injector, the criminal enters the effective range such as the entrance. The injection device is operated at the timing of entering, and the phosphorescent agent can be reliably attached to the criminal.

  A crime prevention phosphorescent agent ejecting apparatus according to an embodiment of the present invention will be described. FIG. 3 is a system configuration diagram of the photoluminescent agent injection device 30 for crime prevention. The crime prevention phosphorescent agent injection device includes an injection device main body 31, a control circuit unit 32 including a power supply unit, an operation switch 33, and a sensor 34. The operation switch 33 is a switch operated by the store clerk when the store clerk discovers a criminal act and determines that the criminal runs away. The operation switch (SW) 33 is preferably attached to the counter. Specifically, the position of the operation switch 33 is desirably in the vicinity of the register or on the back surface of the counter table, and is preferably a place where no erroneous operation is performed. The operation switch 33 presets the injection device main body 31, and the control circuit unit 32 is operated by a passage signal from a sensor 34 attached to the entrance / exit 36, and the actual injection timing is determined. This is also related to the fact that there is a time difference between the robbery criminal and the time to get out of the store, and the effective injection time of the cylinder is short.

  FIG. 4 is a conceptual diagram showing the attachment position of the photoluminescent agent injection device for crime prevention. The injection device main body 31 is attached to the ceiling portion 37 of the entrance / exit 36 of the convenience store 35. Moreover, the operation switch 33 of the light-accumulating agent injection device for crime prevention is attached to the counter. When the sensor 34 is not attached, the ejection device main body 31 is operated by the activation signal of the operation switch 33. Further, instead of providing the sensor 34, it may be interlocked with the opening of the door of the doorway 36. In the case of an automatic door, the signal of the drive unit can be used, and in the case of a manual door, a limit SW signal can be used.

  In the present embodiment, the phosphorescent agent is excited in advance with excitation light including ultraviolet rays. This is because when the phosphorescent agent is sprayed and attached to the robber's clothes, hair, or other body parts, the attachment can be immediately identified even in the dark. Normally, the cylinder in the main body of the injection device is held by the cylinder holder with the nozzle portion inclined so as to face up. Unlike the phosphorescent panel in which the phosphorescent agent is applied planarly, in this embodiment, the phosphor is clogged with liquid in the cylinder. For this reason, even if it irradiates excitation light, excitation light does not easily reach the phosphor in the center of the cylinder. Therefore, the amount of excitation light must be increased accordingly.

  For this reason, the positional relationship between the cylinder and the LED as the excitation light source, the number of installed LEDs, and the like were examined. FIG. 5 is an explanatory diagram showing the positional relationship between the cylinder 44 and the LED 41. Basically, as shown in FIGS. 5 (a) and 5 (b), it is preferable to excite the phosphorescent agent from a position serving as an axial reference on the outer periphery of the cylinder. Therefore, as a combination of the location and number of the LEDs, the phosphorescent effect was examined in three pieces on one side, three on both sides, a total of six pieces, and two on both sides. Moreover, the luminous effect in the case of 10 mm, 20 mm, and 30 mm was examined as the distance between the cylinder and the LED. As a result, three LEDs were used, and the distances from the three LEDs to the outer wall of the cylinder were 10 mm, 20 mm, and 30 mm, respectively.

  Next, the relationship between the irradiation time of the phosphorescent agent and the afterglow time was examined. FIG. 6 is a characteristic diagram showing the relationship between the irradiation time and afterglow time and the remaining light intensity illuminance. Here, as the irradiation time Ts, the residual light intensity illuminance in the case of 15 seconds, 30 seconds, 60 seconds, 5 minutes, 10 minutes, 60 minutes, and 120 minutes was examined. When the irradiation time by the LED is set to 120 minutes, the residual light intensity illuminance during the irradiation time up to 120 minutes is examined and a curve K1 is obtained. When excitation is stopped after 120 minutes, the relationship between the afterglow time Tz and the remaining light intensity illuminance becomes as shown by a curve K2.

  Judging from such characteristics, it can be seen that the residual light intensity illuminance is saturated by irradiation for about 100 minutes. When the saturation value is Lm, an afterglow illuminance L0 of about 1/3 of the saturation value Lm is obtained after irradiation for 100 minutes or more. The marking according to the afterglow illuminance can be identified from the criminal body.

  The structure of the main body of the injection device mainly including the injection mechanism in the present embodiment will be described with reference to FIG. Fig.7 (a) is a side view of an injection device main body, FIG.7 (b) is a back part side view. In FIG. 7, the main body of the injection device has a small main body case 42 and a transparent lid 43 in which an injection mechanism is built. In the present embodiment, the main body case 42 is made of aluminum sheet metal, but may be a molded product using resin. The reason why the lid 43 is transparent is to make the injection mechanism visible and to facilitate inspection of the cylinder state.

  An overview of the cylinder 44 is shown in FIG. The horn 44 includes a cylinder main body 44a, a cylinder cap 44b, a nozzle 44c, and a nozzle guide 45. The cylinder main body 44a is filled with a phosphorescent agent containing a solvent and a compressed gas. A phosphorescent agent containing a solvent or a compressed gas is also called an aerosol. The cylinder main body 44a is a transparent glass molded product and is wrapped with a transparent resin film as an explosion-proof measure. The nozzle guide 45 applies a pressing force from the outside to the straight pipe nozzle 44c, and is integrated with the nozzle 44c by press-fitting to form a nozzle portion. The outer shape of the nozzle guide 45 is Mt. Fuji, and the average outer diameter thereof is larger than the diameter of the opening of the injection lever described later. When a pressing force of 30 mm or more and a stroke of 3 mm is applied to the nozzle 44c or the nozzle guide 45, the cylinder 44 is in an open state.

  As shown in FIG. 7, the injection mechanism is roughly divided into a cylinder holder 46, an operation lock portion 47, an actuator portion 48, a safety prevention lock portion 49, and an arm 50. The cylinder holder 46 is a holder that holds the cylinder 44 and rotates between a standby position and an injection position. When the safety lock 49 is in the locked state, the cylinder holder 46 is held in the locked position from the standby position to the injection position even if the operation lock 47 is in the unlocked state. This locked position is also referred to as a cylinder filling position.

  FIG. 9 shows a structural diagram of the cylinder holder 46 alone. The cylinder holder 46 includes a holder 46a, an injection lever 46b, a hinge portion 46c for the injection lever, a cylinder holder 46d, a cylinder holder hinge 46e, and a locking piece 46f. The holder 46a holds the outer periphery of the cylinder 44, and has two coaxial rotating shafts 46g. One rotating shaft 46g is supported by an arm 51 fixed to the main body case 42, and the other rotating shaft 46g is supported by a cam 48a described later.

  The ejection lever 46b is a plate-like member that rotates relative to the holder 46a via the hinge portion 46c to the first position or the second position. The ejection lever 46b opens the nozzle guide 45 of the cylinder 44 at the first position to close the cylinder 44, and presses the nozzle guide 45 strongly at the second position to open the cylinder 44. The pressing force of the ejection lever 46b in the first position and the pressing force of the ejection lever 46b in the second position are both held by the tensile force of a coil spring (not shown) whose one end is engaged with a part of the holder 46a. Is done. The ejection lever 46 b is provided with an opening that is larger than the outer diameter of the nozzle 44 c of the cylinder 44 and has a diameter equivalent to the effective outer diameter of the nozzle guide 45.

  The hinge portion 46c holds the ejection lever 46b so as to be rotatable with respect to the holder 46a, and a hinge is used here. When the holder 46a and the injection lever 46b are integrally formed of resin, the hinge portion 46c can be integrally formed by reducing the thickness of the fulcrum portion.

  The cylinder holder 46d is a plate-like member that flexibly holds the bottom part of the cylinder 44 via the hinge part 46e with respect to the holder 46a. A resin pad is attached to the cylinder holder 46d so as to be able to follow variations in the length of the cylinder 44 and differences in the shape of the cylinder 44. Variations in length can be absorbed by elastic deformation of the pad, and differences in shape can be accommodated by changing the thickness of the pad.

  The hinge part 46e holds the cylinder holder 46d so as to be rotatable with respect to the holder 46a, and a hinge is also used here. When the holder 46a and the cylinder holder 46d are integrally formed of resin, the hinge portion 46e can be integrally formed with the holder 46a as in the case of the injection lever 46b. The locking piece 46f attached to the holder 46a is a member that engages with a latch lever of an operation lock portion described later in the holder 46a during standby.

  Next, the actuator section 48 will be described with reference to FIGS. 10 (a), (b), and (c). The actuator section 48 includes a cam 48a, a cam follower 48b, a cam follower spring 48c, a hinge connecting lever 48d, and a pin 48e. The cam e48a is a disk-shaped member, and the outer peripheral side surface is a sliding surface having the same rotation radius. The center of the cam 48a is the origin, the vertical direction of the injector attached in a normal posture is the y-axis, the horizontal direction is the x-axis, and the rotation angle from the + x-axis is θ with the origin as the center. In the range of θ = (− 90 ° + Δ) to θ = (+ 270 ° −Δ) in the CW direction, the radius of the sliding surface viewed from the origin is constant. A notch 48f is provided in the range from θ = (+ 270 ° −Δ) to θ = (− 90 ° + Δ). The depth of the notch 48f is D1 when viewed from the sliding surface, and the width of the notch 48f is D2.

  FIG. 10A shows the standby position, FIG. 10B shows the lock position (cylinder loading position), and FIG. 10C shows the injection position. The cam follower 48b is made of a resin having a low friction coefficient and has a convex cross section. The width of the convex portion is narrower than D2, and the length is slightly shorter than D1. The hinge connecting lever 48d is connected so as to be integrated with the cam follower 48b, and is pulled toward the center of the cam 48a by a spring 48c having one end attached to the pin 48e. The cam follower 48b and the hinge connecting lever 48d can be realized by integral molding with resin.

  10A, the cam follower 48b is at a position of θ = 15 °, and the convex portion of the cam follower 48b is on the sliding surface of the cam 48a. Even in the locked position of FIG. 10B, the convex portion of the cam follower 48b is on the sliding surface of the cam 48a. In the injection position of FIG. 10C, the cam follower 48b is at a position of θ = −90 °. At this position, the hinge connecting lever 48d receives a strong tensile force of the spring 48c, and the convex portion of the cam follower 48b fits into the notch 48f of the cam 48a.

  The operation lock portion 47 will be described with reference to FIG. The operation lock portion 47 includes a latch lever 47a, a solenoid 47b, a link lever 47c, and a return spring 47d. The operation lock unit 47 releases the lock in order to rotate the cylinder holder 46 in the standby state to the injection position by energization of the solenoid 47b. The solenoid 47b is of a DC drive type, for example, and performs a drawing operation when DC power is supplied by an AC adapter and a start switch. One end of the return spring 47d is fixed to the main body case 42 via a pin, the other end is engaged with the link lever 47c, and the link lever 47c is pulled to the right in FIG. One end of the latch lever 47a engages with the link lever 47c and is rotatably held by a shaft 47e. An engagement recess 47f is formed in a part of the latch lever 47a and engages with the locking piece 46f of the cylinder holder 46 at the standby position.

  The safety lock portion 49 will be described with reference to FIG. The safety lock portion 49 includes a case 49a, a release lever 49b, a stopper pad 49c, and a release shaft 49d. The safety lock portion 49 holds the cylinder holder 46 at the cylinder loading position. When a new cylinder 44 is loaded into the cylinder holder 46, if the nozzle guide 45 is inadvertently pressed or the cylinder holder 45 is inadvertently brought to the injection position, the phosphorescent agent may be injected. In order to prevent this, a safety lock 49 is provided. When the lid 43 is open, the release lever 49b presses behind the cylinder holder 46 and stops so that the cylinder 44 does not rotate to the injection position. The release lever 49b is pulled toward the front side of the drawing by a coil spring (not shown). When the lid 43 is closed, the release shaft 49d is pushed, and the release lever 49b is pushed in the reverse direction of the paper surface, and the lock at this position is released.

  The main body case 42 is provided with an excitation light source 52 as shown in FIG. FIG. 13A is a plan view of the excitation light source 52, and FIG. 13B is a side view. The excitation light source 52 has a plurality of LEDs 52b attached to an LED substrate 52a, and radiates excitation light including ultraviolet light to a phosphorescent agent in the cylinder 44.

  The operation | movement description which makes an injection mechanism a main part is demonstrated about the light-accumulating agent injection apparatus for crime preventions comprised as mentioned above. To load the cylinder, first the lid 43 is opened. At this time, one end of the release shaft 49d shown in FIG. Next, the release lever 49b is lifted toward the front of the paper surface by the tensile force of the spring.

  In the crime prevention phosphorescent agent injection device in the initial state, it is assumed that the cylinder 44 is not yet filled in the cylinder holder 46 and the actuator section 48 is at the position shown in FIG. The user turns on the operation switch 33 in FIG. Then, when an activation signal is given to the control circuit unit 32 of FIG. 3 and a criminal passing signal is given from the sensor 34, the solenoid 47b is excited for a short time. Immediately after this, the operation lock part 47 of FIG. 7 or FIG. 11 operates, and the latch lever 47a rotates in the CCW direction. Note that the power supply of the control circuit unit 32 may be turned off and the operation lock unit 47 may be moved manually.

  Next, the cylinder holder 46 is manually rotated in the CW direction. At this time, the actuator portion 48 is rotated to the position shown in FIG. 10B, and comes into contact with the tip of the release lever 49b shown in FIG. In this state, the cylinder 44 to which the nozzle guide 45 is attached is loaded into the cylinder holder 46. Next, the cylinder holder 46 is manually rotated in the CCW direction, and the actuator unit 48 is moved to the standby position shown in FIG. At this time, since the solenoid 47b is already in the off state, the locking piece 46f of the cylinder holder 46 is engaged with the engaging recess 47f of the latch lever 47a shown in FIG. Thus, the cylinder holder 46 loaded with the cylinder 44 is locked at the standby position. This state is shown in FIG.

  3 is connected to a commercial power source, the LED of the excitation light source 52 emits light, and ultraviolet light and visible light are output. Since the cylinder main body 44a is made of transparent glass, ultraviolet rays and visible light are incident on the cylinder main body 44a at this position. Thus, the phosphorescent agent is excited and accumulates light.

  Next, suppose a burglar broke into a store, such as a convenience store, and the criminals robbed cash of a register or shoplifted goods. Assume that a store clerk is aware of this robbery and persuades him, but does not respond to it and carries away cash or goods. At this time, the store clerk immediately turns on the operation switch 33. Eventually, when the criminal tries to escape from the doorway 36 as shown in FIG. 4, the sensor 34 in FIG. 3 detects the passage of the criminal. This sensor 34 is a human sensor capable of identifying the direction of the detected object, and outputs a passing signal only to a person who goes out of the store and operates even when a regular customer enters from outside. The control circuit 32 is operated by this passing signal, and the solenoid 47b in FIG. 7 or FIG. 11 is turned on for a short time. The state of the injection mechanism after this is shown in FIG.

  Next, a rotational moment is generated by the dead weight of the cylinder holder 46 holding the phone 44. For this reason, the cylinder holder 46 rotates in the CW direction around the rotation shaft 46g. Since the lid 43 is tightened, the safety prevention lock portion 49 does not operate, and the actuator portion 48 is in the position shown in FIG. 10C, that is, the cylinder holder e2 is in the state shown in FIGS. 16A and 16B. Become. (A) is a side view of an injection device main body, (b) is a back part side view.
