Description

  The present invention relates to a spherical bullet used for a simulated gun, and a soft bullet dedicated to a gravity-fed simulated gun.

  Some of the simulated guns have a simple structure commonly called a silver ball gun, and are particularly popular for young people. It is characterized by being capable of firing a silver spherical bullet only by a trigger operation, as estimated from a common name, and does not require a complicated bullet supply mechanism or a firing mechanism.

  A bullet called a silver ball is made of gypsum or clay having a diameter of about 7 mm. Currently, there are plastic BB bullets for bullets used in simulated guns, and soft bullets using more flexible materials. However, it is natural that even those bullets feel a certain degree of shock when hit, and the same is true for silver ball guns.

  Accordingly, the present inventor has developed a simulated gun system that does not feel the shock of hitting a bullet even when the bullet hits a human skin. It is a completely new mock gun rather than a gun that replaces the silver ball gun, and in other words, it has ultimate safety. The present invention is designed as a bullet suitable for such a simulated gun.

  On the other hand, prior art was investigated, but no applicable or similar ones were found. There is no invention that falls under the concept of soft bullets or soft bullets in the first place. The word “soft” is found in Japanese Patent Publication No. 2007-505286, and in claim 16, there is a description such as a paintball, airsoft ball, “bb” or bullet like a pellet, but it is not explained in the specification. Absent. Therefore, although details are unknown, since it relates to an electric compressed air gun, it is considered to have little relation to the present invention.

Special table 2007-505286

  The present invention has been made in view of the above points, and an object of the present invention is to provide a soft bullet dedicated to a gravity-feeding simulated gun that can be played safely without hitting a person or an object even if hit. Another object of the present invention is to provide a soft bullet dedicated to a gravity feed simulated gun that is surely fed and fired despite being soft.

In order to solve the above-mentioned problems, the present invention provides a means in which a bullet body is formed by plastic molding as a spherical bullet used in a simulated gun, and the plastic is made of a thermoplastic elastic body. It is a thing.
The thermoplastic elastic body is desired to have a hardness in the range of 5 to 40 degrees in the measurement method of JIS K6253A.

  The bullet body is formed by plastic molding, but not all plastics can be molded by the molding method. As a result of trial and error, it was found that the hardness of the thermoplastic elastic body applied to the soft bullet according to the present invention is appropriate in the range of 5 to 40 degrees in the measuring method of JIS K6253A.

  If the hardness is less than 5, it is difficult if not impossible to mold, and the gate trace after separation from the runner becomes large. On the other hand, when the hardness exceeds 40, molding is facilitated, but it is not suitable for the purpose of the present invention because it is too hard. In addition, the measuring method of JIS K6253A is prescribed | regulated that the type A durometer for medium-sized general rubber object which is neither high nor low is used.

  In particular, the bullet body hardness is in the range of 8 to 12 degrees in the measurement method of JIS K6253A, and the surface of the bullet body has a fine powder lubricant, the soft bullet according to the present invention. It is suitable as. Hardness issues are also associated with the supply of soft bullets. When the hardness is less than 20 degrees, molding is possible, but the impact of friction between the bullet bodies that are in contact with each other or between the bullet bodies and the bullet supply path becomes significant. There was a tendency to have a major hindrance to the flight. Accordingly, the lubricant is used for the purpose of reducing bullet friction.

  The hardness of 8 to 12 degrees is suitable as the hardness of the soft bullet of the present invention, but the influence of friction appears strongly as described above. Therefore, in order to reduce the influence of friction between the bullet bodies that are in contact with each other or between the bullet body and the bullet supply path, and to enable the supply of soft bullets by the action of gravity alone, the use of a lubricant is necessary. desired. As the lubricant, a fine powder which will be described later is suitable. The fine powder is easily sprinkled on the surface of the bullet body and can be easily washed off if necessary.

  The plastic constituting the bullet body is mainly composed of SEBS (styrene-ethylene-butylene-styrene block copolymer), and the finely divided lubricant contains at least one or both of talc and starch. What is configured is desirable. Plastics mainly composed of SEBS (styrene-ethylene / butylene-styrene block copolymer) are used as a material that is safe for the human body, for example, medical devices, toothbrushes, etc. As a soft bullet according to the present invention, Is also preferable.

  Moreover, as a fine powder-like anti-friction agent belonging to the above, natural pollen, Siccalol (registered trademark), baby powder (registered trademark) and the like are suitable. Heavenly pollen is known to have yellow crow's starch as its main component, and the latter two are known to have talc and starch as its main components. It should be noted that the lubricant can be attached to the bullet body at any time before the soft bullet is used.

  In addition, for example, silicon oil or the like can be used, and it has been confirmed through experiments that it is effective. However, the above-mentioned, for example, Siccalol (registered trademark), for example, has obtained better results in reducing friction, and the safety to the human body has been confirmed by many years of use, and it is cheaper and more obtainable. Easy.

  The bullet bodies are arranged vertically and horizontally, and there are runner frames on all or part of the outer circumference of the above bullet body array. All bullets are connected to each other, and the bullets and runner frames are connected. Such a configuration is preferable as the present invention.

  Since the present invention is configured and operates as described above, it is possible to provide a soft bullet dedicated to a completely new gravity-fed simulated gun that is molded using a thermoplastic elastic body having a very low hardness. There is an effect that can be done. The soft bullet according to the present invention can be supplied only by gravity despite being very soft and lightweight, and the soft bullet can play safely without hitting people or things even if hit. Because it can be used, it demonstrates ultimate safety. Furthermore, according to the present invention, although it is soft, the contact friction with the bullet is reduced. As a result, the bullet is reliably separated and fed, and stable firing is possible. Can get a good trajectory.

It is explanatory drawing which shows an example of the soft bullet for exclusive use of the gravity supply simulation gun which concerns on this invention, A is sectional drawing of one soft bullet, B is an external view of the soft bullet which consists of many pieces. It is explanatory drawing which shows the internal mechanism of the gravity supply simulation gun using the same soft bullet.

  Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments. FIG. 1 shows a soft bullet BB dedicated to a gravity feed simulated gun according to the present invention. A bullet body 1 is made of a plastic sphere. The soft bullet BB of the example is a thermoplastic elastic body mainly composed of SEBS (styrene-ethylene-butylene-styrene block copolymer).

  In the soft bullet BB in the embodiment, the hardness of the bullet body is in the range of 8 to 12 degrees in the measuring method of JIS K6253A. Using the thermoplastic elastic body, those having a hardness of 8, 10, or 12 degrees were injection molded. Although there is no great difference in the experimental results of these three soft bullets, the example having a hardness of 10 degrees was particularly optimal in terms of the total balance of formability, friction reduction, launchability, and shocklessness. .

  Further, a fine powder lubricant 2 mainly composed of talc and starch adheres to the surface of the bullet body 1. This anti-friction agent 2 is obtained by applying Siccalol (registered trademark) to a molded soft bullet by sprinkling it uniformly on the surface of the bullet body. The anti-friction agent 2 can be attached to the runner frame 3 which will be described below. However, it is better to sprinkle all of the lubricant before it is supplied to the simulated gun after it has been separated one by one. Will get.

In FIG. 1B, the bullet bodies 1 are arranged vertically and horizontally, and there are runner frames 3 on the whole or a part of the outer periphery of the arrangement of the bullet bodies 1, and all the bullet bodies 1 and the bullet bodies 1 and the runner frames 3 are arranged. Shows what is connected and configured. Branch runners 4 having different thicknesses are connected to the bullet body 1 directly connected to the runner 3, and are configured to be used separately one by one at the time of use.
<Effect confirmation experiment>
In order to confirm a part of the effect of the soft bullet according to the present invention, an experiment for comparing the power was performed, and the result is shown below. In the experiment, a soft bullet and a comparative BB bullet (substantially the same mass as the soft bullet) were collided with the sensor part of the push gauge at the same initial velocity, and the collision energy was measured (the antifriction agent is Siccaroll (registered trademark)). It was used.).
<Experimental conditions>
・ Soft bullet mass 0.109g (average of five measurements)
・ Soft bullet hardness 10 degrees (JIS K6253A)
・ BB bullet mass (comparative example) 0.114 g (average of five measurements)
-Initial bullet velocity 60m / s
・ Sensor position 1cm from the muzzle
・ Launching device Adjusted air cocking gun <Experimental result>




Table 1

Unit: Newton (N)
According to Table 1, the kinetic energy obtained by firing the soft bullet of the present invention under the above-described experimental conditions is 1.53 N with an average value of five times. On the other hand, the kinetic energy obtained by firing the BB bullet under the same experimental conditions is also 2.86 N. The bullet mass is almost the same, so the work should be almost the same, but the kinetic energy of the soft bullet according to the present invention obtained by the push gauge is only 53% of that of the comparative example. ing. This indicates that since it is a soft bullet, it was compressed by collision with the sensor and energy was consumed for its deformation. Therefore, the external force exerted on the human body is extremely small. For reference, when a large number of people including young people were interviewed about the touch when the soft bullet according to the present invention was hit in the palm of the hand, the result was that the touch of the bullet hit almost without any exception. .

  Such a soft bullet BB according to the present invention is used for a simulated gun belonging to a so-called silver ball gun. FIG. 2 shows a particularly improved simulated gun 10, where 11 is a space through which a gun cavity, that is, a bullet B to be fired, has a loading part 12 set in its inner part, A certain muzzle 13 opens outward.

  The bullet loading unit 12 has a bullet holder 12a that holds the supplied bullet B until firing. The bullet holder 12 a is formed with a protrusion sufficient to temporarily stop the bullet, and is provided on both the left and right side surfaces of the bullet loading portion 12. Either or both of the bullet B and the bullet holder 12a are formed of a material that can be deformed to pass the bullet B by being pushed by the advancing striker 15, for example, a material such as nylon (registered trademark) or rubber. ing.

  Therefore, even if it is a hard bullet of the same level as a general BB bullet, the bullet holder 12a can pass elastically when it is struck by a striker 15 described later. Further, in the case of a soft bullet that deforms itself when pressed with a fingertip, the soft bullet can elastically deform and pass through.

  The rear of the gun cavity 11 is continuous with a striker moving path 14, and a striker 15 (described later) is provided so as to be capable of moving forward and backward. The striker 15 is lowered to a position behind the bullet inlet when retreating, and the front end of the striker 15 reaches the loading section 12 and presses the bullet B when moving forward. Above the striker movement path 14, a supply path 16 is located adjacent to the bullet B and supplied to the loading unit 12 by gravity.

  As a means for gravity feed, the supply path 16 is composed of a rear portion made of a horizontal portion and a front portion made of an inclined surface. The tip of the supply path 16 constitutes a bullet opening 17 for dropping the bullet B on the bullet loading portion 12, and a bullet feed opening 18 is formed at the rear end thereof so that a required number of bullets B can be filled therebetween. Yes. The front portion of the supply path 16 changes its direction almost vertically through a smooth curved surface from the inclined surface toward the bullet opening 17 (for this reason, the bullet opening 17 is also slightly narrowed), and the inclined surface on which the bullet B slides down. A detaching member 20 is provided at a part thereof.

  The separating member 20 is rotatably provided by a support shaft 19 at the upper end of the rear end, so that the lower end of the front end is in contact with the striker moving path 14 and the supply path 16. When the striker 15 is retracted, the separating member 20 is locked to a stopper 21 provided at a portion that also serves as the upper frame of the striker moving path 14, and does not open any further. Further, when the striker 15 moves forward, the upper surface of the striker 15 is slid, and in this state, the distal end side of the separating member 20 enters the supply path 16 to narrow the loading port 17 and stop the movement of the bullet B halfway. Has been.

  A trigger 22 is provided as a bullet firing mechanism, and the trigger 22 is provided by a slide member 23 integral therewith so that a forward / backward moving portion 24 provided on the gun body side can be moved forward and backward. An engagement member 25 is attached to the slide member 23 so as to be rotatable around a support shaft 26. An engagement portion 27 of the engagement member 25 is provided with an engagement counterpart portion 28 provided on the striker 15, as will be described later. It is placed in an engageable relationship.

  That is, when the trigger 22 is pulled, the engaging portion 27 and the engaging counterpart portion 28 are engaged, the striker 15 is retracted, and the engaging portion 27 is disengaged by the rotation of the engaging portion 27. Thus, the striker 15 is provided in a relationship that enables the advance. Therefore, the striker 15 compresses the main spring 30 when retreating, and moves forward instantaneously by the accumulated spring force.

  A rear spring receiver 29 of the main spring 30 is provided on the gun body side, and a front spring receiver 31 is provided at the rear end of the striker 15. The forward spring receiver 31 has a forward limit defined by the structure 32 inside the gun body as a stopper.

  Since the soft bullet according to the present invention is configured as described above, it can be appropriately gravity fed and fired. The simulated gun of FIG. 2 is provided with a means for mechanically separating the bullet at the firing position from the next bullet in particular, thereby cutting off the influence of the next bullet, obtaining the straightness of the bullet, and flying. It is intended to improve performance such as increasing the distance. Therefore, the soft bullet BB according to the present invention does not have to use the simulated gun of FIG. 2, and can naturally be fired even if a silver ball gun having a conventional gravity feed structure is used.
