Description

[0001]
BACKGROUND OF THE INVENTION
[0002]
The present invention relates to a technique for adhering a paint to a criminal or the like in order to facilitate tracking and discovery.
[0003]
[Prior art]
[0004]
In order to facilitate the tracking, discovery, etc., as a device for attaching a paint to a criminal or the like, a ball configured to contain the paint and to be easily ruptured by an impact caused by a collision is known.
[0005]
[Problems to be solved by the invention]
[0006]
Now, according to a ball containing such paint, by hitting the ball and hitting a criminal who made a robbery, etc. or a vehicle used for its clothes or escape, The paint contained in the ruptured ball can be attached to a criminal or the like, and subsequent tracking and discovery can be facilitated.
[0007]
However, in fact, unless the person is skilled in pitching technology, it is difficult to hit a criminal or the like from a distance so that the ball is not harmed. Therefore, not only can the painter not adhere to the criminal, but it may accidentally hit an irrelevant device and damage it.
[0008]
In addition, the ball needs to be configured to be ruptured by an impact caused by a collision with a criminal or the like. Actually, the pitching speed and the pitching method differ depending on the pitcher, and the target is a human or a vehicle. Depending on the impact, the impact applied to the ball differs depending on the collision, so no matter how you set the ball's ease of bursting, it will burst with the force applied at the time of throwing, or it will not burst even if you hit a criminal etc. It is easy for problems to occur.
[0009]
Then, this invention makes it a subject to provide the apparatus which can make a paint adhere to the target person easily and reliably.
[0010]
[Means for Solving the Problems]
[0011]
In order to achieve the above object, the present invention provides, for example, a liquid gun for ejecting liquid,
[0012]
A liquid bullet containing a liquid in a hermetically contained manner in a replaceable manner, and a gun cavity having an injection port for injecting the liquid,
[0013]
An operation unit;
[0014]
In response to the operation of the operation unit, the liquid bullet mounted in the gun cavity is pressed and deformed under pressure, or a pressing mechanism that moves and pressurizes and deforms,
[0015]
The pressure bullet is deformed by the pressing mechanism, or the sealing of the liquid bullet is broken with the movement and pressure deformation, and the liquid contained in the liquid bullet is ejected from the ejection port. Provide a liquid gun.
[0016]
According to such a first liquid gun, the liquid bullet that has been pressure-deformed or moved and pressure-deformed by the pressing mechanism has its hermeticity broken and releases the liquid. Then, the liquid which is at a higher pressure than the external pressure at this time is ejected vigorously from the ejection port.
[0017]
Therefore, a liquid, for example, a paint can be sprayed on a target far away only by aiming at the target and operating the operation unit without requiring a special technique. Further, since the liquid is ejected instead of a solid material such as a conventional ball containing paint, irrelevant equipment and the like are rarely damaged.
[0018]
In order to achieve the above object, the present invention provides, for example, a hollow cylinder,
[0019]
An elastic membrane that closes one bottom surface of the cylinder with a sealing property;
[0020]
A sealing portion that closes the other bottom surface of the cylindrical body with a sealing property;
[0021]
A liquid contained in a space sealed by the cylindrical body, the membrane, and a sealing member;
[0022]
The sealed portion has a piston portion that is in sliding contact with the inner periphery of the cylindrical body,
[0023]
The piston portion is configured so that when a force of a predetermined level or more is applied from the outside toward the one bottom surface, the inside of the cylindrical body is moved toward the one bottom surface in accordance with the force applied from the outside to the one bottom surface direction. A second liquid bullet is provided that moves.
[0024]
Further, in order to achieve the above object, the present invention provides, as a device for firing the liquid contained in the liquid bullet as described above, a gun cavity in which the liquid bullet is replaceably mounted,
[0025]
An operation unit;
[0026]
In response to the operation of the operation unit, a pressing mechanism that presses the piston part of the liquid bullet mounted in the gun cavity in the one bottom surface direction,
[0027]
The gun cavity provides a second liquid gun characterized by having a small hole provided in front of the membrane of the mounted liquid bullet.
[0028]
Here, this second liquid gun is
[0029]
A breaking means for forcibly breaking the film when the film swells forward by a predetermined amount may be provided.
[0030]
According to such a second liquid bullet and, for example, the second liquid gun, the piston portion pressed by the pressing mechanism moves inside the cylindrical body toward the one bottom surface and is accommodated in the liquid bullet. Increase the pressure of the discharged liquid. The membrane then swells forward and eventually breaks to release the liquid. Then, the liquid which is at a higher pressure than the external pressure at this time is ejected with a greater force than the hole leading to the outside.
[0031]
Therefore, a liquid, for example, a paint can be sprayed on a target far away only by aiming at the target and operating the operation unit without requiring a special technique. Further, since the liquid is ejected instead of a solid material such as a conventional ball containing paint, irrelevant equipment and the like are rarely damaged.
[0032]
Further, not only the pressing force of the pressing mechanism but also the elastic film is used to increase the pressure of the liquid, so that the liquid ejection momentum can be increased as compared with the case where only the pressing force is used.
[0033]
Further, the present invention is a liquid gun for injecting a liquid to achieve the above-described problem,
[0034]
A gun cavity for storing a liquid bullet hermetically containing liquid in an internal space in an exchangeable manner;
[0035]
An operation unit;
[0036]
A pressing mechanism that presses the liquid bullet mounted in the gun cavity in the direction of the injection port in response to the operation of the operation unit;
[0037]
The gun cavity is provided with a needle portion projecting in the accommodated liquid bullet direction, in a tubular shape, connected to the inside of the tubular shape for ejecting liquid,
[0038]
The needle portion is inserted into the internal space of the liquid bullet by the movement and collision of the liquid bullet due to the pressing of the pressing mechanism, and the liquid is pressurized by the deformation of the liquid bullet due to the pressing of the pressing mechanism, A third liquid gun is provided which is ejected from the ejection port through the inside of the tubular shape of the inserted needle part.
[0039]
Further, as a liquid bullet suitable for such a third liquid gun, it has a hollow bellows body and two bottom surfaces that respectively seal both ends of the bellows body.
A third liquid bullet is provided, comprising the cylinder and a liquid contained in a space sealed by two bottom surfaces.
[0041]
According to such a third liquid bullet and, for example, the third liquid gun, the needle portion is inserted into the internal space of the liquid bullet by the movement and collision of the liquid bullet due to the pressing of the pressing mechanism. Then, the liquid is pressurized by the deformation of the liquid bullet by the pressing of the pressing mechanism, and is ejected vigorously from the ejection port through the inside of the tubular shape of the inserted needle portion.
[0042]
Therefore, a liquid, for example, a paint can be sprayed on a target far away only by aiming at the target and operating the operation unit without requiring a special technique. Further, since the liquid is ejected instead of a solid material such as a conventional ball containing paint, irrelevant equipment and the like are rarely damaged.

DETAILED DESCRIPTION OF THE INVENTION
[0044]
Hereinafter, embodiments of the present invention will be described.
[0045]
First, the first embodiment will be described.
[0046]
FIG. 1 schematically shows the structure of a paint gun and paint bullets according to the first embodiment.
[0047]
In the figure, 100 represents a paint bullet, and 200 represents a paint gun. Here, the paint bullet 100 is used by being attached to the paint gun 200 in a replaceable manner.
[0048]
First, the paint bullet 100 will be described.
[0049]
FIG. 2 a shows the appearance of the paint bullet 10, and FIG. 2 b shows a schematic structure of the paint bullet 200.
[0050]
As shown in the figure, the paint bullet 200 has a substantially hollow cylindrical shape, and one bottom surface of the cylinder 110 forming the cylindrical side surface is sealed with an elastic film 115 made of an elastic material such as synthetic rubber. Has been. Moreover, it has the piston 120 provided so that the inside of the cylinder 110 was slidable. The piston 120 is fixed to the cylinder 110 on the side opposite to the elastic film 115 by a sealing material 130 so as to seal the space surrounded by the cylinder 110, the elastic film 115, and the piston 120 with a relatively weak adhesive force. . The space sealed by the cylinder 110, the elastic film 115, and the piston 120 is filled with a colored paint 150.
[0051]
Now, returning to FIG. 1, such a paint bullet 100 is mounted in a paint gun 200 as shown.
[0052]
As shown in the figure, the paint gun 200 includes a lid part 201, a gun cavity part 210, a grip part 202, a trigger part 203, a pressing head 204, a spring 205, and a spring 209.
[0053]
Further, the gun cavity part 210 has an injection port 211 that is a small hole provided at the tip thereof, a needle part 212 provided slightly inside the tip, and a lid part 213 for taking in and out the paint bullet 100 inside and outside the gun cavity part 210. And a hole 214 for mounting an urging rod described later.
[0054]
The pressing head 204 is fixed to the tip of the spring 205. Further, the pressing head 204 and the trigger portion 203 have locking portions 207 and 208 for engaging with each other so as to be releasable by operating the trigger portion 203 when the spring 205 is contracted as shown in the figure. Yes. Further, the trigger portion 203 is urged by a spring 209 in a direction in which the lower portion of the trigger portion 203 is directed in the opposite direction to the grip portion 202.
[0055]
Now, the state shown in FIG. 1 shows a state where the paint is ready for firing. Hereinafter, the operation from this state to the firing of the paint will be described.
[0056]
At the time of use, the user grips the grip part 202, directs the injection port 211 toward the target, and pulls the trigger part 203. Then, as shown in FIG. 3, the engagement between the pressing head 204 and the trigger portion 203 is released, and the spring 205 that is in a contracted state extends with an urging force, moves the pressing head 204, and moves the coating bullet 100. The piston 120 is made to collide.
[0057]
Then, due to this collision, the fixed state due to the weak adhesive force between the piston 120 and the cylinder 110 by the sealing material 130 is destroyed, and the piston 120 slides in the cylinder 110 according to the force applied from the outside.
[0058]
The spring 205 continues to extend after the pressing head 204 collides with the piston 120 of the paint bullet 100, and moves the piston 120 in the cylinder 110 toward the elastic film 115. As a result, the pressure of the paint 150 increases, and the elastic film 115 swells in the direction of the injection port 211 due to this pressure.
[0059]
Eventually, when the elastic film 115 swells and comes into contact with the needle portion 212, the elastic film 115 breaks and is released by this, and the paint 150 that is at a pressure higher than atmospheric pressure at that time is applied to the injection port 211. It is ejected vigorously toward the target. Eventually, when the spring 205 is fully extended and the atmospheric pressure and pressure become the same, the injection of the paint 150 is stopped. Note that the elastic film 115 is forcibly broken by the needle portion 212 in this way so that the ejection position of the elastic film 115 is not blocked by the broken elastic film 115. Even for control.
[0060]
Now, after firing the paint as described above, an operation when preparing for launching the paint in preparation for the next launch will be described.
[0061]
First, the biasing bar 206 is inserted from the hole 214 and attached to the pressing head 204. This attachment is performed, for example, by providing a male screw on the biasing rod 206 and a female screw on the pressing head 204 and screwing the biasing rod 206 into the pressing head 204. When the urging rod 206 is attached, the urging rod 206 is then pulled from the outside, and the spring 205 is contracted as indicated by a broken line in the drawing. Then, when the spring 205 is contracted to the state shown in FIG. 1 and the application of force to the biasing rod 206 is stopped, the pressing head 204 and the trigger portion 203 are engaged again. Therefore, the biasing bar 206 is removed from the pressing head 204. Then, as indicated by a broken line in the figure, the lid portion 213 is opened, the used paint break 100 is taken out, the unused paint break 100 is attached instead, and the lid portion 213 is closed.
[0062]
Now, the state shown in FIG. 1 is obtained and preparation for the next launch is completed.
[0063]
The first embodiment of the present invention has been described above.
[0064]
As described above, according to the paint bullet 100 and the paint gun 200 according to the first embodiment, it is possible to aim at the target and pull away the trigger portion 203 without requiring a special technique. Can be sprayed with paint. Further, since the paint itself is injected instead of a solid material such as a conventional ball containing paint, there is little damage to irrelevant equipment. Of course, the targeted offenders will not be injured unnecessarily.
[0065]
Further, not only the pressing force of the piston 120 (the force of the spring 205 in the above) but also the use of the elastic film 115 has a structure in which the paint is greatly increased in pressure, which is more than when only the pressing force of the piston 120 is used. It is possible to increase the momentum of the paint injection, and to improve the reach of the paint and the straightness of the injected paint. Further, the momentum of injection of the paint can be controlled relatively easily by selecting the material of the elastic film 115 and selecting and setting the position where the elastic film 115 is forcibly broken by the needle 212.
[0066]
In addition, since the paint is encapsulated in the form of the paint bullet 100, handling is easy. In addition, the deterioration of the paint over time is small due to its airtightness.
[0067]
By the way, in the first embodiment, instead of the needle portion 212, an arbitrary breaking mechanism that forcibly breaks the elastic film 115 when the elastic film 115 swells by a predetermined amount may be provided. The film 115 itself may be made of a material that breaks when the elastic film 115 expands by a predetermined amount.
[0068]
In the above description, the urging force of the spring 205 is used as a force for pressing the piston 120. However, other force may be used. For example, as shown in FIG. 4, a gas cylinder 300 filled with high-pressure gas is replaceably mounted in the paint gun 200, and the nozzle 301 of the gas cylinder 300 is released by operating the trigger 203. The force of the high pressure gas may be used as a force for pressing the piston 120.
[0069]
Hereinafter, a second embodiment of the present invention will be described.
[0070]
FIG. 5 schematically shows the structure of the paint gun and paint bullet according to the second embodiment.
[0071]
In the figure, 400 represents a paint bullet, and 500 represents a paint gun. Here, the paint bullet 400 is used by being attached to the paint gun 500 in a replaceable manner.
[0072]
First, the paint bullet 400 will be described.
[0073]
FIG. 6 a shows the appearance of the paint bullet 10, and FIG. 6 b shows the schematic structure of the paint bullet 200.
[0074]
As shown in the drawing, the paint bullet 400 has a substantially cylindrical hollow shape having a bellows structure that can expand and contract on the side surface of the cylinder. In addition, an ear 401 that protrudes in the warp direction is provided on one bottom surface of the paint bullet 400. The sealed space inside the paint bullet 400 is filled with a colored paint 450.
[0075]
As a material of the paint bullet 400, for example, a chemical resin having relatively flexibility is used.
[0076]
Now, returning to FIG. 1, such a paint bullet 100 is mounted in a paint gun 500 as shown.
[0077]
As in the first embodiment, the paint gun 200 includes a lid portion 201, a gun cavity portion 210, a grip portion 202, a trigger portion 203, a pressing head 204, a spring 205, a spring 209, a lid portion 213, and the biasing rod described above. And a hole 214 for mounting the.
[0078]
Further, the gun cavity part 210 has a needle part 520 having a hollow internal passage connecting the injection port 521 and the inside of the gun cavity part 210 at the distal end portion thereof. Further, the end of the needle part 520 on the paint bullet 400 side has a sharp shape.
[0079]
Further, the gun cavity portion 210 has a slit 530 for locking the ear portion 401 of the mounted paint bullet 400, and the slit 530 prevents the paint bullet 400 from freely moving in the axial direction. ing.
[0080]
Now, the state shown in FIG. 5 shows a state where the paint is ready for firing. Hereinafter, the operation from this state to the firing of the paint will be described.
[0081]
At the time of use, the user grips the grip part 202, directs the injection port 521 toward the target, and pulls the trigger part 203. Then, as shown in FIG. 7, the engagement between the pressing head 204 and the trigger portion 203 is released, and the spring 205 in the contracted state extends with an urging force, moves the pressing head 204, Collide.
[0082]
Then, due to this collision, the ear 401 is twisted backward and comes out of the slit 530, and the paint bullet 400 moves forward and eventually collides with the needle 520.
[0083]
Then, the needle portion 520 breaks through the bottom surface of the paint bullet 400 opposite to the side where the ear portion 401 is provided and enters the paint bullet 400. On the other hand, the coating bullet 400 continues to move forward while being pressed by the pressing head 204, and the bottom surface opposite to the side on which the ear portion 401 is provided collides with the inner wall in front of the gun cavity portion 210. The bellows structure of the bullet 400 is remarkably shrunk and the pressure of the internal paint increases.
[0084]
When the needle portion 520 enters the paint bullet 400 in the above operation, the paint 450 in the paint bullet 400 is at a pressure higher than the atmospheric pressure at least after colliding with the inner wall in front of the gun cavity portion 210. Through the passage inside the needle portion 52, the jet is ejected vigorously from the injection port 521 toward the target. Eventually, when the spring 205 is fully extended and the atmospheric pressure and the pressure of the paint 450 become the same, the injection of the paint 150 is stopped.
[0085]
Note that the operation when preparing for the launch of the paint in preparation for the next launch after firing the paint in this way is the same as in the first embodiment.
[0086]
The second embodiment of the present invention has been described above.
[0087]
Here, in the second embodiment described above, a mechanism using the ear 401 and the slit 530 is used as a mechanism for suppressing the free movement of the paint bullet 400 in the direction of the needle 520 when not in use. A mechanism that releases the inhibition of the paint bullet 400 in the direction of the needle portion 520 in conjunction with the operation of the portion 203 may be provided.
[0088]
Further, in the second embodiment described above, the paint bullet 400 has a structure in which a bellows structure is provided on the side surface so that the paint bullet 400 can easily contract. However, the paint bullet 400 is made according to an external force such as rubber or vinyl. Such a bellows structure is not necessarily required when formed using a deformable material.
[0089]
Also in the second embodiment, as in the first embodiment, the force of the high pressure gas by the gas cylinder 300 as shown in FIG. 4 is used instead of the urging force of the spring 205 as the force for pressing the piston 120. It may be used as a force for pressing the piston 120.
[0090]
In each of the above embodiments, the paint gun 200 has been described as being required to be replaced one time, that is, each time the paint bullet 100/400 is fired, the paint bullet 100/400 needs to be replaced. The gun 200 may be a multi-shot gun equipped with a plurality of paint bullets 100/400 and capable of sequentially firing the paint of each paint bullet. For example, two paint bullets 100/400 may be mounted and the paints of each paint bullet 100/400 may be fired sequentially as described above according to the trigger pull angle.
[0091]
Further, instead of the paint 150/450, a scented liquid or any other liquid may be accommodated in the paint bullet and used.
[0092]
In addition, the paint bullet 100/400 is not only a gun-type device such as the paint gun 200 as described above, but an arbitrary mechanism having an arbitrary mechanism for injecting paint from the paint bullet 100/400 as described above. It may be used for the injection of paint in the above apparatus.
[0093]
【The invention's effect】
[0094]
As described above, according to the present invention, it is possible to provide a device that can easily and surely attach a paint to a target person.
