Abstract

PROBLEM TO BE SOLVED: To easily and surely mark with a coating material on a target. SOLUTION: When a trigger part 203 is pulled, a spring 205 is released to make a press head 204 to collide with a piston 120 for a coating material shot 100, which is fitted to a coating material gun exchangeable. The fixed state of the piston 120 to a cylinder 110 is broken and the piston 120 is moved to an elastic film 15 direction in the cylinder 110. As a result, when the pressure of the coating material is increased, the elastic film 115 swells in a ejecting port 211 direction and brought into contact with a needle part 212 to be broken. Then, the released coating material 150 is ejected toward the target from the ejecting port 211 vigorously.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

[0002] The present invention relates to a technique for attaching a paint to a criminal or the like in order to facilitate tracking, finding, and the like.

[0003]

[Prior art]

[0004] As a device for adhering paint to a criminal or the like in order to facilitate the tracking, finding, etc., a ball configured to contain the paint and to be easily burst by an impact due to a collision is known. ing.

[0005]

[Problems to be solved by the invention]

[0006] According to the ball containing such paint, by throwing the ball and hitting the criminal who has made a robbery or the vehicle used for its clothing or escape, the criminal and the like The paint contained in the ball ruptured by the collision can be attached to a criminal or the like, and subsequent tracking and discovery can be facilitated.

[0007] However, in practice, it is difficult for a person who is not skilled in pitching technology to hit the ball with a criminal or the like from a distance so as not to harm himself. Therefore, not only can a painter not adhere to a criminal or the like, but there is also a case where the painter accidentally hits an unrelated device or the like and damages it.

[0008] Further, the ball needs to be configured to burst by the impact of a collision with a criminal or the like. However, in actuality, the pitching speed and the pitching method differ depending on the pitcher, and the target may be different. Since the impact applied to the ball by collision differs depending on the human or the vehicle, no matter how easy the ball is set to burst, the ball will burst with the force applied at the time of throwing or burst even if hit by a criminal etc. Problems such as failure to do so are likely to occur.

[0009] Therefore, an object of the present invention is to provide an apparatus that can easily and surely apply a paint to a target person.

[0010]

[Means for Solving the Problems]

[0011] In order to achieve the above object, the present invention provides, for example, a liquid gun for injecting a liquid,

A gun cavity having an ejection opening for ejecting a liquid while accommodating a liquid bullet in which a liquid is hermetically accommodated;

An operation unit;

A pressure mechanism that presses and deforms, or moves and presses and deforms, the liquid bullet mounted in the gun cavity in response to the operation of the operation unit;

[0015] The seal of the liquid bullet is destroyed by the pressure deformation or the movement and the pressure deformation by the pressing mechanism, and the liquid contained in the liquid bullet is ejected from the ejection port. A first liquid gun is provided.

[0016] According to the first liquid gun, the liquid bullet that has been deformed under pressure, or moved and deformed under pressure by the pressing mechanism, loses hermeticity and releases the liquid. Then, the liquid having a higher pressure than the external pressure at this point is ejected from the ejection port with vigor.

[0017] Therefore, it is possible to pour a liquid, for example, a paint, on a distant target simply by aiming at the target and operating the operation unit without requiring any special technique. Further, since a liquid is ejected instead of a solid material such as a conventional ball containing a paint, there is little possibility of damage to unrelated devices and the like.

[0018] In order to achieve the above object, the present invention provides, for example, a hollow cylindrical body,

An elastic membrane that closes one bottom surface of the cylindrical body with hermeticity;

A sealing portion for closing the other bottom surface of the cylindrical body with hermeticity;

A liquid contained in a space sealed by the cylindrical body, the membrane, and a sealing member;

[0022] The sealing portion has a piston portion slidably contacting the inner periphery of the cylinder,

When a force of a predetermined level or more is applied in the direction of the one bottom surface from the outside, the piston portion moves the inside of the cylindrical body in response to the force applied in the direction of the one bottom surface from the outside. A second liquid bullet is provided that moves in a bottom direction.

[0024] In order to achieve the above object, the present invention provides a device for ejecting a liquid contained in a liquid ammunition as described above, wherein a gun cavity for exchanging the liquid ammunition is provided;

An operation unit;

A pressing mechanism for pressing a piston portion of the liquid bullet mounted in the gun cavity toward the one bottom surface in response to an operation of the operating portion;

[0027] A second liquid gun is provided, wherein the gun cavity has a small hole provided in front of the membrane of the mounted liquid bullet.

Here, this second liquid gun is

[0029] A breaking means for forcibly breaking the film when the film expands forward by a predetermined amount may be provided.

Increase the pressure of the liquid contained in the liquid ammunition. The membrane then swells forward and eventually breaks, releasing the liquid. Then, the liquid having a higher pressure than the external pressure at this point is ejected from the hole leading to the outside with vigor.

[0031] Therefore, it is also possible to pour a liquid, for example, a paint, on a distant target simply by aiming at the target and operating the operation unit without requiring any special technique. Further, since a liquid is ejected instead of a solid material such as a conventional ball containing a paint, there is little possibility of damage to unrelated devices and the like.

Further, not only the pressing force of the pressing mechanism but also the structure in which the pressure of the liquid is increased by an elastic film,
The momentum of ejecting the liquid can be increased as compared with the case where only the pressing force is used.

[0033] In order to achieve the above object, the present invention provides a liquid gun for injecting a liquid,

A barrel for exchangeably containing a liquid ammunition in which the liquid is hermetically contained in the internal space;

An operation unit;

A pressing mechanism for pressing a liquid bullet mounted in a gun cavity toward the ejection port in response to an operation of the operation unit;

[0037] The gun cavity is provided with a needle portion projecting in the direction of the stored liquid bullet and connecting the inside of the tube shape for injecting a liquid,

The needle portion is inserted into the internal space of the liquid bullet by the movement and collision of the liquid bullet by the pressing of the pressing mechanism, and the liquid is added by the deformation of the liquid bullet by the pressing of the pressing mechanism. A third liquid gun is characterized in that the liquid gun is ejected from the ejection port through the inside of the tubular shape of the inserted needle portion.

A liquid bullet suitable for such a third liquid gun has a hollow bellows body and two bottom surfaces for sealing both ends of the bellows body.

[0040] A third liquid bullet comprising the cylindrical body and the liquid stored in a space closed by two bottom surfaces is provided.

According to such a third liquid bullet and, for example, the third liquid gun, the needle section moves the liquid bullet due to the pressing of the pressing mechanism and collides with the inner space of the liquid bullet. The liquid is inserted therein, the liquid is pressurized by the deformation of the liquid bullet by the pressing of the pressing mechanism, and is vigorously ejected from the ejection port through the inside of the tubular shape of the inserted needle portion.

[0042] Therefore, it is possible to pour a liquid, for example, a paint, on a distant target simply by aiming at the target and operating the operation unit without requiring any special technique. Further, since a liquid is ejected instead of a solid material such as a conventional ball containing a paint, there is little possibility of damage to unrelated devices and the like.

[0043]

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described.

First, the first embodiment will be described.

FIG. 1 schematically shows the structure of a paint gun and a paint bullet according to the first embodiment.

In the figure, 100 denotes a paint bullet and 200 denotes a paint gun. Here, the paint bullet 100 is replaceable, and the paint gun 200 is replaced.
It is used by being attached to.

First, the paint bullet 100 will be described.

FIG. 2A shows the appearance of the paint bullet 10 and FIG.
1 shows a schematic structure of 00.

As shown in the drawing, the paint bullet 200 has a substantially hollow cylindrical shape, and one bottom surface of a cylinder 110 forming a cylindrical side surface has an elastic film made of an elastic material such as synthetic rubber. Sealed at 115. A piston 120 slidably provided inside the cylinder 110
have. The piston 120 is provided on the opposite side of the elastic film 115 of the cylinder 110 by the sealing material 130, with relatively weak adhesive force, with the thin lid 110, the elastic film 115,
It is fixed so as to seal the space surrounded by the piston 120. The thin lid 110 and the elastic film 11
5. The space sealed by the piston 120 is filled with a colored paint 150.

Now, returning to FIG.
Is mounted in the paint gun 200 as shown.

The paint gun 200 is, as shown in FIG.
1. Gun cavity part 210, grip part 202, trigger part 203, pressing head 204, spring 205, spring 209
And

The gun barrel 210 has an injection port 211 which is a small hole provided at the tip thereof, a needle 212 provided slightly inside the tip, and a gun bullet 210 for inserting and removing the paint bullet 100 inside and outside the gun barrel 210. It has a lid 213 and a hole 214 for mounting an urging rod to be described later.

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 operation of the trigger portion 203 in a state where the spring 205 is contracted as shown in the figure. I have. Further, the trigger portion 203 is urged by a spring 209 in a direction in which a lower portion of the trigger portion 203 is directed in a direction opposite to the grip portion 202.

The state shown in FIG. 1 shows a state in which the paint is ready for firing. Hereinafter, the operation from this state to the discharge of the paint will be described.

In use, the user grips the grip portion 202, pulls the trigger portion 203 with the ejection port 211 facing the target. Then, as shown in FIG. 3, the engagement between the pressing head 204 and the trigger portion 203 is released, and the spring 205 in the contracted state expands with an urging force, moves the pressing head 204, and moves the paint bullet 100. The piston 120 is caused to collide.

Then, due to this collision, the fixed state of the piston 120 and the cylinder 110 due to the weak adhesive force by the sealing material 130 is broken, and the piston 120 is
In the middle, the object slides according to the force applied from the outside.

[0058] The spring 205 continues to extend even after the pressing head 204 collides with the piston 120 of the paint bullet 100, and the piston 120 moves the elastic film 115 through the cylinder 110.
Move in the direction. Then, along with this, the pressure of the paint 150 increases, and this pressure causes the elastic film 115 to expand in the direction of the injection port 211.

Eventually, the elastic film 115 expands, and the needle portion 2
Upon contact with the coating film 12, the elastic film 115 breaks, and the paint 150 released at this time and having a pressure higher than the atmospheric pressure at that time is vigorously ejected from the ejection port 211 toward the target. Eventually, when the spring 205 is fully extended and the atmospheric pressure becomes equal to the pressure, the injection of the paint 150 stops. In addition, as described above, by the needle portion 212,
The reason why the elastic film 115 is forcibly broken is also to control the position where the elastic film 115 is broken so that the injection port 211 is not blocked by the broken elastic film 115.

Next, after the paint is fired in this manner,
The operation when preparing for the launch of the paint in preparation for the next launch will be described.

[0061] First, the urging rod 206 is inserted through the hole 214,
It is attached to the pressing head 204. This attachment is performed, for example, by providing a male screw on the urging rod 206 and a female screw on the pressing head 204 and screwing the urging rod 206 into the pressing head 204. When the urging rod 206 is attached, the urging rod 206 is pulled from the outside, and the spring 205 is contracted as shown by a broken line in the figure. And FIG.
The spring 205 is contracted to the state shown in FIG.
When the application of the force to 6 is stopped, the pressing head 204 and the trigger portion 203 are engaged again. Then, the urging rod 206 is removed from the pressing head 204. Then, as shown by the broken line in the figure, the lid portion 213 is opened, the used paint cutout 100 is taken out, and the unused paint cutout 10 is used instead.
0 is attached, and the lid 213 is closed.

[0062] The state shown in FIG. 1 is thus obtained, and preparations for the next firing are completed.

[0063] The first embodiment of the present invention has been described above.

As described above, the paint bullet 1 according to the first embodiment
According to 00 and the paint gun 200, no special technique is required, just aiming at the target and pulling the trigger 203,
You can pour paint on distant targets. Further, since the paint itself is injected instead of a solid material such as a conventional ball containing the paint, there is little possibility of damage to unrelated equipment and the like. Of course, there is no needless injury to the targeted criminals.

[0065] Further, not only the pressing force of the piston 120 (above, the force of the spring 205) but also the use of the elastic film 115 is used to greatly increase the pressure of the paint.
As compared with the case where only the pressing force of the piston 120 is used, the momentum of the paint injection can be increased, and the reach distance of the paint and the straightness of the injected paint can be improved. In addition, selection of the material of the elastic film 115 and selection of the position where the elastic film 115 is forcibly broken by the needle portion 212 can be performed by selecting the force of the paint injection.
It can be controlled relatively easily by setting.

Further, since the paint is encapsulated in the form of the paint bullet 100, the handling is easy. Further, the paint is less deteriorated with time due to its airtightness.

In the first embodiment, instead of the needle portion 212, when the elastic film 115 expands by a predetermined amount,
An arbitrary breaking mechanism for breaking the elastic film 115 may be provided, or the elastic film 115 itself may be made of a material that breaks when the elastic film 115 expands by a predetermined amount.

In the above description, the urging force of the spring 205 is used as the force for pressing the piston 120, but another force may be used. For example, as shown in FIG.
Is exchangeably mounted in the paint gun 200, and the gas cylinder 3
The force of the high-pressure gas may be used as a force for pressing the piston 120 by releasing the jet port 301 of 00 by operating the trigger 203.

Hereinafter, a second embodiment of the present invention will be described.

FIG. 5 schematically shows the structure of a paint gun and a paint bullet according to the second embodiment.

In the drawing, reference numeral 400 denotes a paint bullet, and 500 denotes a paint gun. Here, the paint bullet 400 is replaceable and the paint gun 500
It is used by being attached to.

First, the paint bullet 400 will be described.

FIG. 6A shows the appearance of the paint bullet 10 and FIG.
1 shows a schematic structure of 00.

[0074] As shown in the figure, the paint bullet 400 has a substantially cylindrical hollow shape having a bellows structure that can be extended and contracted on the side surface of the cylinder. Further, on one bottom surface of the paint bullet 400, an ear portion 401 protruding in the warp direction is provided. 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 softness is used.

Returning to FIG. 1, such a paint bullet 100
Is mounted in a paint gun 500 as shown.

[0077] The paint gun 200 is similar to the first embodiment,
Lid 201, gun cavity 210, grip 202, trigger 2
03, a pressing head 204, a spring 205, a spring 209, a lid 213, and a hole 214 for mounting the above-described urging rod.

Further, the gun cavity 210 has a needle 52 having a hollow internal passage connecting the injection port 521 and the inside of the gun cavity 210.
0 at its tip. The end of the needle portion 520 on the side of the paint bullet 400 has a sharp shape.

[0079] In the gun cavity 210, the mounted paint bullet 4
There is a slit 530 for locking the ear 401 of the 00, and the slit 530 prevents free movement of the paint bullet 400 in the axial direction.

The state shown in FIG. 5 shows a state in which the paint is ready for firing. Hereinafter, the operation from this state to the discharge of the paint will be described.

At the time of use, the user grips the grip portion 202, pulls the trigger portion 203 with the ejection port 521 facing the target. Then, as shown in FIG. 7, the engagement between the pressing head 204 and the trigger portion 203 is released, and the spring 205 which has been in a contracted state expands with an urging force, moves the pressing head 204, and Make them 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 paint 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 front inner wall of the gun cavity 210, and thereafter, the paint bullet 400 Bullet 40
The zero bellows structure shrinks remarkably, and the pressure of the paint inside increases.

In the above operation, when the needle portion 520 enters the inside of the paint bullet 400, the paint 45 inside the paint bullet 400 is removed.
At 0, since the pressure becomes higher than the atmospheric pressure at least after colliding with the inner wall in front of the gun cavity 210, it is ejected from the ejection port 521 to the target through the passage inside the needle 52 with a vigorous force. . Then, when the spring 205 is fully extended and the atmospheric pressure and the pressure of the paint 450 become the same, the ejection of the paint 150 stops.

[0085] In addition, after the paint is fired in this manner, the operation for preparing for the launch of the paint in preparation for the next fire is as follows.
This is the same as the first embodiment.

[0086] The second embodiment of the present invention has been described above.

Here, in the second embodiment described above, the mechanism using the ear 401 and the slit 530 is used as a mechanism for suppressing the free movement of the paint bullet 400 toward the needle 520 when not in use. Alternatively, a mechanism may be provided to release the inhibition of the paint bullet 400 in the direction of the needle portion 520 in conjunction with the operation of the trigger portion 203.

In the second embodiment, the paint bullet 400
Although the bellows structure was provided on the side surface so that the paint bullet 400 was easily shrunk, the paint bullet 400 was formed using a material that can be deformed in response to an external force, such as rubber or vinyl. Such a bellows structure is not always necessary.

[0089] Also in the second embodiment, similarly to the first embodiment, instead of the urging force of the spring 205, the high-pressure gas generated by the gas cylinder 300 as shown in FIG. Force of piston 120
May be used as a pressing force.

In each of the above embodiments, the paint gun 200 has been described as a single fire, that is, it is necessary to replace the paint bullet 100/400 each time the paint of one paint bullet 100/400 is fired. However, the paint gun 200 may have a plurality of paint bullets 100/400, and may have a plurality of paint bullets capable of sequentially firing paint of each paint bullet. For example, two paint bullets 100/400 may be mounted, and the paint of each paint bullet 100/400 may be sequentially fired as described above according to the trigger angle.

[0091] Instead of the paint 150/450, a liquid having an odor or any other liquid may be contained in a paint bullet and used.

[0092] The paint bullet 100/400 is not limited to a gun-type device such as the paint gun 200 described above,
It may be used for injection of paint in an arbitrary device having an arbitrary mechanism for injecting paint from the paint bullet 100/400 as described above.

[0093]

【The invention's effect】

[0094] As described above, according to the present invention, it is possible to provide an apparatus that can easily and surely apply a paint to a target person.
