Description

Technical field to which the invention belongs

  The present invention relates to a portable spray type security device, and more particularly, to a spray type security device that can be carried and used effectively by children as well as adults.

  There are several types of portable security devices for crimes on the road and the like. When classified by function, a warning type alerts the criminal with a warning sound, etc. and informs that the victim is being damaged, a marking type that attaches a mark such as paint to the fleeing criminal to facilitate criminal investigation, and dislikes the criminal Such a bad smell, paint, tearing gas and the like to spray the culprit repellent type.

  When adults use these security devices, many people are accustomed to handling various devices and have a high ability to learn the operation and operation procedures. wide. However, if you encounter a sudden attack by a thug on the street or the like, even an adult can easily lose calmness, so even if you carry a security device, you can use that device effectively. It is not always possible to use it. In the case of children, there are few security devices suitable for use by children, and it is often impossible to make good use of the devices, so it can be said that it is more difficult to utilize the security devices effectively.

There are several types of conventional portable security devices as described above, and the alarm type includes, for example, a pager. The alarm type is effective when there is a third party in the vicinity, but the effect cannot be expected in a less popular place.
As examples of the marking type, for example, a “security aerosol injector” (Patent Literature 1), a “liquid gun and liquid ammunition” (Patent Literature 2), and the like have been proposed.

  FIG. 16 is a cross-sectional view illustrating a configuration of an aerosol spray device “security aerosol injector” disclosed in Patent Document 1. In this security aerosol sprayer, an aluminum can 101 is filled with a marking liquid 102 and a nitrogen gas 103. The container is held in one hand, and a button 106 is opened by depressing a button 105 with a finger. 102 is to be sprayed. The nozzle 104 is a “rod-jet type”, and it is stated that by setting the pressure of the nitrogen gas 103 to 0.88 MPa, the marking liquid 102 can be blown up to about 10 m away. The area around the button 105 is covered with a cap 107 except for a part where a finger is inserted.

  FIG. 17 is a cross-sectional view showing a configuration of a pistol type spray device “liquid gun and liquid ammunition” disclosed in Patent Document 2. In the case of this liquid gun, when the trigger 203 is pulled, the spring 205 is released to press the pressing head 204, and the pressing head 204 collides with the piston 202 of the paint bullet 200. When the piston 202 is pressed, the paint bullet 200 moves, the elastic film 206 comes into contact with the needle portion 207 and breaks, and the paint 210 in the paint bullet 200 is sprayed from the injection port 201.

  An aerosol-type or pistol-type spray device as described above is usually used as the criminal repelling type spray device. Examples of the propellant include tear gas for repelling and defending molesters, and include, for example, CN gas (chloroacetophenone), CS gas (ortho-chlorobenzylidene-malononitrile), and an extract of red pepper as a main component. And the like. Further, in order to prevent damages to persons other than the repulsion target such as thugs, there has been proposed a tear water solution having a weakened tear action and a spray device therefor (for example, Patent Document 3). The aqueous tear solution disclosed in Patent Document 3 is obtained by diluting an ethanol solution containing L-menthol, a tear stimulating substance, with water. In addition, as the propellant, a liquid or gas having a corrosive odor, a filth odor, or the like, a highly adhesive substance, and the like have been proposed.

  As described above, the marking type and the criminal repulsion type security devices mainly use the aerosol type shown in FIG. 16 or the pistol type shown in FIG. When using these devices, in the case of a pistol type, the user holds the handle portion 208 with one hand, points the injection port 201 corresponding to the muzzle toward the other party, and pulls the trigger 203 to perform injection. Also in the case of the aerosol type, the container is ejected by holding the cylindrical container body (aluminum can 101) with one hand in an upright position, pointing the nozzle (injection port) 104 toward the other party and pressing the valve opening / closing button 105.

  Pistol-type and aerosol-type security devices have the advantage that they are relatively easy to use, and that they can be easily sprayed to a nearby person. However, if it is assumed that children such as school children use the device, the security device is not necessarily suitable for children.

  For example, regardless of the pistol type or the aerosol type, since the injection port 201 and the nozzle 104 are sprayed toward the opponent, an operation of aiming at the opponent is required. Such an action is immediately detected by the other party, and in the case of a child or a weak adult, the security device is easily lifted up with his / her strength and cannot be used. Furthermore, even before use, there is a high possibility that the other party can easily recognize the security spray from the form. In addition, the tear-providing gas may be harmed to the user, and may cause health damage to a child without physical strength.

In addition, in order to use the security device effectively, it is necessary to keep it ready for use at any time. To this end, it is preferable to carry the device with it attached to the body or school bag, if possible, so that it can be used immediately. However, in the case of the conventional security device, there is a disadvantage that the other party realizes at first glance that the device is a security device. In addition, there is a problem that when carrying the device in a state of being hidden in a bag or the like, it is necessary to remove it, so that the device cannot be used immediately.

Hereinafter, a spray type security device according to an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing an appearance of a spray-type security device 1 according to the first embodiment. As shown in FIG. 1, the spray-type security device 1 includes a cylindrical container body 11 and a cap 12 attached to the container body 11. The cap 12 is provided with an opening 12 a at a position corresponding to the surface of the nozzle 13 where the nozzle hole 13 a is opened. Further, a button 14 is attached to the cap portion 12, and when the button 14 is pressed, the nozzle portion 13 is pushed into the container main body 11 side, and the liquid substance in the container main body 11 passes through the nozzle hole 13a. Through this, the fuel is injected in the central axis direction of the container body 11.

  FIG. 2 is a cross-sectional view showing the structure of the spray-type security device 1 according to Embodiment 1, and shows a cross-sectional structure taken along the line II-II 'shown in FIG. In this specification, the container main body 11 means a portion surrounded by the container 16, and the nozzle portion 13 means a portion of the nozzle mechanism located outside the container 16.

  As shown in FIG. 2, the container body 11 includes a container 16, a liquid substance 17 contained in the container 16, a pressurizing gas 18 for pressurizing the liquid substance 17 and ejecting the liquid substance 17 from a nozzle hole 13 a, A dip tube 19a for guiding the liquid substance 17 to the nozzle section 13 via the valve section 19 and the opening / closing valve section 19 is included. As is clear from FIG. 2, the container main body 11 has substantially the same structure as the general aerosol type spray device shown in FIG.

  The container 16 includes a body 16a, a head 16b, and a bottom 16c. Of these, the trunk 16a can be made of aluminum or a steel plate subjected to a surface treatment such as plating. On the other hand, the head 16b and the bottom 16c are preferably made of a steel plate that has been subjected to a surface treatment such as plating from the viewpoint of strength. Further, the shape of the body 16b is cylindrical, and may be rectangular, but is preferably cylindrical from the viewpoint of strength and handleability. The size of the container 16 is preferably about 20 to about 50 mm in diameter and about 50 to about 200 mm in length because the spray-type security device 1 is portable. Particularly for children, the diameter is preferably about 40 mm or less and the length is about 150 mm or less.

  The liquid substance 17 may be any substance that is effective in repelling a criminal such as a thug and has a characteristic that can be ejected from the nozzle hole 13a. Further, the liquid substance 17 includes a substance that is liquid in the container 16 and gasifies when injected. These liquid substances 17 include, for example, paints commonly used in crime prevention sprays, chemicals that generate an irritating odor such as ammonia, and odors, as well as properties that resemble human and animal feces. A substance that gives a feeling, a sticky and poorly liquid rubber, a liquid glue, and the like can be appropriately selected according to the application and the user. It should be noted that the above-mentioned gas generating tearing gas may be used, but may cause harm to human health. Therefore, it is better not to use tearing agents especially for spray-type crime prevention devices for children.

  The pressurizing gas 18 may be a compressed gas used in an ordinary aerosol type spray, for example, a liquefied gas vaporized in a container 16 such as LPG (liquefied petroleum gas) or DME (dimethyl ether), or a carbon dioxide gas or a nitrogen gas. A compressed gas such as a gas can be used.

  The structure and mechanism of the dip tube 19a and the valve unit 19 for opening and closing, and the method of filling the container 16 with the pressurizing gas 18 and the liquid substance 17 are the same as those of an ordinary aerosol type spraying device, so that they can be used. Description is omitted. However, the valve portion may be a device normally used in an aerosol spray device, but in the case of the spray security device according to the first embodiment, the valve portion may be used with an inclination close to sideways or downward. Therefore, it is more preferable to use a type capable of jetting even in an inverted state.

  FIG. 3 is a partial cross-sectional perspective view showing the cap part 12, the nozzle part 13, and the button 14 of the spray-type security device 1. FIG. 4 is a partially enlarged view showing a cross-sectional structure taken along the line IV-IV ′ shown in FIG. It is sectional drawing. FIGS. 5A and 5B are plan views showing the relationship between the movement of the nozzle locking portion 14a of the button 14 and the nozzle portion 13. FIG. 5A shows a state in which the nozzle portion 13 is locked, and FIG. It is a figure showing the state where a stop was canceled and nozzle part 13 moved to container body part 11 side. Hereinafter, an apparatus configuration for opening the valve of the valve section 19 will be described with reference to FIGS.

  The cap portion 12 is made of an elastic resin such as polypropylene or vinyl chloride. A button 14 is provided on a part of the cap part 12 as shown in FIGS. As shown in FIGS. 3 and 4, the button 14 has an L-shape when viewed from the side, and has a nozzle locking portion 14a and an opening 14b formed at one end, and a fixed end at the other end. 14c.

  The nozzle unit 13 includes a nozzle head 13b and a pipe 13c. The central axis of the nozzle 13 is substantially the same as the central axis of the container body 11. Although it may be the same as the central axis of the container body 11, it is not always necessary to be the same if it is substantially parallel. The pipe 13c connects between the nozzle head 13b and the valve portion 19 shown in FIG. 2 so that the liquid substance 17 can flow therethrough. Further, the pipe 13c is formed of a rigid metal, for example, a material such as stainless steel, and can transmit a pressing force acting on the nozzle head 13b to the valve portion 19.

  The nozzle head 13b is formed of a resin such as polypropylene or vinyl chloride, and has at least one nozzle hole 13a on the surface on the ejection end side. The number of the nozzle holes 13a, the nozzle diameter, and the like are determined by the flow characteristics of the liquid material 17, the ejection distance of the liquid material 17, the ejection angle (spread angle of the liquid material), the size of the droplet after ejection, and the pressure of the pressurizing gas 18. It is preferable to select as appropriate according to the conditions such as.

  An annular projection 13d is formed on the container body 11 side of the nozzle head 13b. The projection 13d is a receiving portion for the coil spring 20. The nozzle head 13b, that is, the nozzle 13 is urged toward the container body 11 by the coil spring 20 incorporated between the protrusion 13d and the upper bottom 12b of the cap 12. As shown in FIG. 5, a locking portion 14a of the button 14 is interposed between the nozzle portion 13 and the container main body portion 11, and serves as a spacer. In this state, even if the nozzle part 13 is urged by the coil spring 20, the nozzle part 13 is not pushed into the container body part 11 side, so that the liquid substance 17 is not ejected from the nozzle hole 13a.

  5A and 5B are a plan view and a side cross-sectional view showing the relationship between the movement of the nozzle unit 13 and the button 14. FIG. 5A shows a state before the nozzle unit 13 is pressed down, and FIG. 5B shows a state before the nozzle unit 13 is pressed down. FIG. An opening 14 b is formed at one end of the button 14, and a portion between the opening 14 b and an end face on one end of the button 14 is a nozzle locking portion 14 a. The inner diameter of the opening 14b is larger than the outer diameter of the lower end of the nozzle head 13b. As is apparent from FIG. 5A, normally, the nozzle locking portion 14a prevents the nozzle portion 13 from being pushed into the container main body portion 11 side.

  On the other hand, as shown in FIG. 5B, when the button 14 is pushed in and the nozzle locking portion 14a is separated from the lower end surface of the nozzle head 13b, the nozzle portion 13 is reduced in thickness to the nozzle locking portion 14a. It is pushed into the container body 11 by a corresponding distance. As a result, the valve in the valve section 19 is opened, and the liquid substance 17 is ejected from the nozzle hole 13a. Since the nozzle portion 13 is pushed by the coil spring 20, once the nozzle portion 13 is pushed in, almost all of the liquid substance 17 in the container body 11 can be ejected even if the button 14 is not kept pressed. .

  Also, in the spray-type security device 1 according to the first embodiment, the outside of the buttons 14 and 15 is covered with paper or the like in order to prevent accidental spraying while carrying. Is also good. If it is covered with something with little elasticity such as paper, even if there is something that touches the button part when carrying it, it is unlikely that the button will be pressed, and when used it can be broken with just a little push with your finger . Therefore, it is possible to reduce the risk of the button being pressed during carrying, and to improve the handleability.

  In addition, a shutter that closes the opening 12a when not in use may be provided in the opening 12a provided at a position facing the nozzle hole 13a of the cap 12, so that the nozzle 13 may be protected.

  Further, in the first embodiment, the example of the coil spring 20 has been described for urging the nozzle portion 13 toward the container main body portion 11, but the spring may not be a coil spring. A spring capable of pushing the nozzle portion 13 toward the container body 11 or a member having the same function as the spring may be used.

  In the spray-type security device 1 according to the first embodiment, an example in which the button 14 has an L-shape in a side view formed integrally with the cap portion 12 has been described, but the button 14 is not necessarily required to have an L-shape in a side view. It is not necessary to be integral with the cap portion 12.

  FIG. 6 is a plan view showing a button 15 according to another embodiment. The button 15 shown in FIG. 6 is of a rotary type, and includes a nozzle locking portion 15a, a fulcrum 15b, and a touch portion 15c. The fulcrum 15b of the button 15 is fixed to the cap portion 12 or the container main body 11, and the nozzle locking portion 15a is rotatable in a direction substantially perpendicular to the central axis of the container main body 11. Therefore, by pressing the touch portion 15c with a finger, the button 15 can be rotated in the direction of the arrow shown in FIG. 6, and the nozzle locking portion 15a can be shifted from the locking position of the nozzle head 13b. By this operation, the nozzle 13 is pushed down, and the liquid substance 17 is ejected.

  Further, the buttons are not limited to the types shown in FIGS. Any structure may be used as long as the nozzle portion 13 is prevented from being pushed in when not in use, and the operation can be canceled when in use. In addition, for example, there is a case where the user does not want to apply a returning force of the button 14 to the nozzle unit 13 after pressing the button 14 illustrated in FIGS. 2 to 4.

  FIG. 7 is a cross-sectional view showing an example of a button 14A having a mechanism for preventing reversion according to another embodiment, wherein (a) is before pressing the button 14A and (b) is after pressing the button 14A. The state of is shown. A projection 14d is provided below the nozzle locking portion 14a of the button 14A. When the button 14A is pushed in, the projection 14d is hooked on the end of the base 16d at the upper end of the container body 11. With such a simple mechanism, it is possible to prevent the button 14A from returning backward.

  FIG. 8 is a diagram showing a spray-type security device 2 according to the second embodiment, in which (a) is an external perspective view, and (b) is a cross-sectional view taken along the line VIII-VIII ′ shown in (a). is there. In the spray-type security device 2 shown in FIG. 8, the spray-type security device 1 described with reference to FIGS. 1 to 7 is further provided with an alarm sound generating means outside the container body 11. That is, as is apparent from the external perspective view shown in FIG. 8A, the alarm sound generating device 21 that is electrically operated is attached to the outside of the container body 11.

  As shown in FIG. 8B, the alarm sound generating device 21 includes a power source 23 such as a dry battery and an alarm 24. As the alarm 24, for example, a buzzer, a bell, an electronic sound generator, or the like can be used. A circuit (not shown) for electrically connecting the power supply 23 and the alarm 24 is turned on and off by a switch 25 provided in the cap portion 12A, as shown in an example in FIG. 8B. The switch 25 includes a plus (or minus) side terminal 25a, a minus (or plus) side terminal 25b, and a conduction end 25c.
