Description

This device has a piston device that fires bullets by compressing and exhausting gas such as air, and experiencing the actual gun firing (simultaneous fire / single fire or simulated fire in the model gun) by the operation of the piston part It relates to a toy gun that can be used.

<Prior art issues and usefulness of the present invention>
In conventional toy guns (model guns, gas blowback air guns, manual and electric air cocking guns), the recoil spring specifications are limited (fixed) to the specifications set by the manufacturer. I had to enjoy it.
The presence of the recoil spring is an important part that determines the toy gun's continuous firing cycle and the air velocity of the air gun, and the manufacturer's setting / development intention does not necessarily match the user's wishes, but does not match the wishes Led to “insufficiency” for the product.
For example, even if you raise one continuous firing cycle of a toy gun, “It is more realistic to use the same continuous firing cycle as a real gun.” “It ’s better to be a little faster than a real gun”, “I want to fire a lot of bullets in a fast cycle anyway”, or conversely, “The target point shifts due to the reaction at the time of firing or the vibration of the gun body and shoots a waste bullet that deviates from the target For that purpose, it is easier to control if the fire cycle is a little slower. "
The user's preference for solving this conflicting problem cannot be handled with just one recoil spring. In order to realize the greatest common divisor performance, which seems to be the majority from those opinions, there is a reality that manufacturers have decided the specifications of one recoil spring.

Users who are unsatisfied with the manufacturer's specifications can only buy a recoil spring of a different specification that is close to their wishes, and in most cases, even the optional items are not in the market. In other words, the current situation is that the “unsatisfactory” that the user has had cannot be resolved.
Therefore, if a new concept with a variable recoil spring capability is completed, users who are dissatisfied with the “insufficiency” of the conventional product will be proposed to develop and enjoy the new phase. be able to.
That is,
〇 Variable firing cycle: Can be matched to individual user's wishes as described above.
〇Variable bullet speed ... Changes in bullet speed affect the elasticity and flight distance. This elastic collection and flight distance do not improve as the bullet speed increases. There are the weight of the BB bullet used and the best match bullet speed. For example, when a light bullet is fired at a high speed, the air resistance is large and an adverse effect occurs. When throwing a ping-pong ball, it bends itself, and a phenomenon similar to a symptom that does not reach the target appears. In other words, if the bullet speed is increased too much, the collecting performance will be reduced. The BB bullets / collection performance / velocity used in this way have a causal relationship that cannot be ignored, which is very attractive to high-end users who have such knowledge.
O Stability of performance in gas blowback air guns ... In gas blowback air guns, where the ambient air temperature has a large effect on gas pressure, a decrease in gas pressure due to "vaporization cooling" significantly reduces performance. In order to improve it, it is most effective to eliminate the cooling around the gas tank, but reducing the structural load that leads to malfunctions is also one of the solutions. In the case of a recoil spring, the operating resistance can be reduced by making it variable. It can be said that the structure is useful for reducing the malfunction occurrence rate.

In the prior art, the capacity is determined by the specifications such as the strength and repulsion force of the recoil spring that operates the piston, and is fixed. So if you want to change its performance, you have to replace it with another stronger or weaker recoil spring.
If the user wants to change the capacity of the recoil spring (usually called a piston spring in an electric air cocking gun), conventionally, a spacer such as a washer is used to make it stronger. Or the technique of cutting and weakening the spring itself has been used. However, since there was no consideration for such usage at the design stage of the manufacturer, there was a limit to the ability change due to the structure.
As described above, in the conventional model, the compression / restoring force of the recoil spring (or piston spring) is fixed, and no member capable of changing its capacity is added.

A schematic diagram of a conventional air compression type manual or electric air cocking gun is shown in FIG.
In the example of FIG. 16, a recoil spring (or piston spring) 101 is attached in a freely stretchable manner between a piston 103 movably held in a cylinder 102 and a spring guide 104 installed at the rear of the barrel.
The compression / restoring force of the recoil spring (or piston spring) 101 in the above conventional model is fixed.
In contrast to this, as shown in FIG. 17, the recoil spring (or piston spring) 201 is arranged using the space 202 provided in the rear part of the barrel, but in this case as well, the ability of the recoil spring (or piston spring) is improved. The variable function is not added.

In order to solve the above problems, an adjuster or a spacer is added to the recoil spring mechanism in the present invention. The adjuster or spacer can be arbitrarily fixed to the spring guide of the recoil spring, and even with the same recoil spring, the repulsive force (extension force) can be changed to change the ability of the gun's continuous firing cycle, velocity, etc. It is.

That is, the recoil spring repulsion force adjustment mechanism in the toy gun of the present invention is a toy gun having a recoil spring disposed between a piston disposed in the barrel or a movable portion in the engine section and a spring guide disposed at the rear of the barrel. A large-diameter adjuster is attached to the outer periphery of the spring guide provided on the movable part side in the piston or the engine part or the spring guide installed at the rear part of the barrel so as to be movable back and forth along the length direction of the spring guide, By engaging with the recoil spring, the adjuster can be advanced and retracted to adjust the repulsive force of the recoil spring.

The recoiling spring repulsive force adjustment mechanism in the toy gun of the present invention has a large-diameter adjuster attached so as to be able to advance and retreat along the length direction of the spring guide, and has a female thread formed on its inner periphery. The male guide provided on the outer periphery of the spring guide is engaged with the female screw so that the large-diameter adjuster can be advanced and retracted.

In the recoil spring repulsive force adjustment mechanism in the toy gun according to the present invention, the large-diameter adjuster attached so as to be able to advance and retreat along the length direction of the spring guide has a plate shape and a female screw formed on the inner periphery thereof. The male guide provided on the outer periphery of the spring guide is engaged with the female screw so that the large-diameter adjuster can be advanced and retracted.

In the mechanism for adjusting the repulsion force of the recoil spring in the toy gun according to the present invention, the large-diameter adjuster attached so as to be able to advance and retreat along the length direction of the spring guide has a plurality of pin holes along the length direction at appropriate intervals. Alternatively, a screw hole is formed, and a large diameter is obtained by inserting a set pin or a set screw into any one of the positioning hole provided in the spring guide and the plurality of pin holes or screw holes of the large diameter adjuster. It is also characterized in that the adjuster can be advanced and retracted.

In the mechanism for adjusting the repulsion force of the recoil spring in the toy gun according to the present invention, the plurality of pin holes or screw holes of the large diameter adjuster attached so as to be able to advance and retreat along the length direction of the spring guide include all the large diameter adjusters. A large diameter is formed by inserting a set pin or a set screw into any one of a positioning hole provided in the spring guide and a plurality of pin holes or screw holes of the large diameter adjuster. It is also characterized in that the adjuster can be advanced and retracted more finely.

In the toy gun according to the present invention, the repulsion force adjusting mechanism of the recoil spring is a toy gun having a recoil spring disposed between a piston disposed in the barrel or a movable portion in the engine section and a spring guide disposed at the rear of the barrel. A cylindrical adjuster is attached to an end of a spring guide provided on the movable part side of the piston or the engine part or a spring guide installed on the rear part of the barrel, and the guide base is movable forward and backward along the length direction of the cylindrical adjuster. Is attached to the piston or the movable part in the engine part or the rear part of the barrel, and the cylindrical adjuster is engaged with the recoil spring, so that the adjuster can be advanced and retracted to adjust the repulsive force of the recoil spring. It is a feature.

In the toy gun according to the present invention, the repulsion force adjusting mechanism of the recoil spring is a toy gun having a recoil spring disposed between a piston disposed in the barrel or a movable portion in the engine section and a spring guide disposed at the rear of the barrel. A spacer having a predetermined length is detachably attached to the back of the spring guide installed at the rear part of the barrel, and the spacer having a different length is appropriately replaced by engaging the spring guide with the recoil spring. The repulsion force of the recoil spring can be adjusted.

As described above, if the position of the adjuster is retracted or the position of the spring guide is retracted by the spacer, the repulsion force of the recoil spring becomes weak. As a result, the forward speed of the piston is also reduced, and the flow rate at which the air in the cylinder is sent to the barrel is also reduced. Therefore, the bullet speed becomes slow.
At the same time, when the piston is retracted, the force for compressing the recoil spring can be reduced. Therefore, if the retraction is performed with the same force, the retreat speed becomes faster, and the firing cycle becomes faster.
On the other hand, when the position of the adjuster is advanced or the position of the spring guide is advanced by the spacer, the recoil spring is compressed by that amount, and a series of operations starts. The forward speed of the piston increases due to the increased repulsion force of the recoil spring, and the flow speed at which the air in the cylinder is sent to the barrel also increases, thus increasing the bullet speed.
At the same time, the resistance when retracting the piston is increased by the amount of compression of the recoil spring, resulting in a slower series of firing cycles.
From the above, it is difficult to understand the difference in single shot, but it becomes remarkable when fired continuously. This adjuster and spacer can be applied to all toy guns that use recoil springs, such as gas blowback air guns and model guns.

The mechanism for adjusting the repulsion force of the recoil spring in the toy gun of the present invention is configured as described above, and an adjuster is installed at the front end or rear end of the recoil spring to change its position, or a spacer is provided at the rear of the barrel. The force for pressing the recoil spring is made variable by changing the position of the spring guide.
As a result, the forward speed of the cylinder is also changed. As a result, the bullet speed and the forward / backward cycle of the cylinder are made variable.
As described above, the user himself / herself can make adjustments to a product that meets the needs of the user, which has not been possible with the conventional product, such as a change in the firing cycle, a change in bullet velocity, and an improvement in the collection elasticity.

A first embodiment of a recoil spring repulsive force adjustment mechanism in a toy gun according to the present invention is shown in FIGS. 1 (a), 1 (b) and 1 (c).
The recoil spring repulsion force adjusting mechanism 11 in the toy gun according to the present embodiment is a recoil disposed between a piston disposed in the barrel shown in FIG. 12 or the like or a movable portion in the engine section and a spring guide disposed in the rear section of the barrel. Applies to toy guns with springs. Hereinafter, a case where a recoil spring is disposed between the piston and a spring guide disposed at the rear part of the barrel will be described.
That is, a large-diameter cylindrical adjuster 13 is attached on the outer periphery of the spring guide 12 so as to be able to advance and retreat along the length direction of the spring guide 12, and is engaged with the recoil spring 14 at the front end thereof. Thus, if the cylindrical adjuster 13 is advanced and retracted, the repulsive force of the recoil spring 14 can be adjusted.
In this embodiment, a male threaded portion 12a is formed on the outer periphery of the spring guide 12 with an appropriate width, while a female threaded portion 13a is formed on the inner peripheral surface of the cylindrical adjuster 13 and assembled. The tubular adjuster 13 can be advanced and retracted by turning.

As described above, when the position of the adjuster 13 is retracted, the repulsive force of the recoil spring 14 is weakened. As a result, the forward speed of the piston is also reduced, and the flow rate at which the air in the cylinder is sent to the barrel is also reduced. Therefore, the bullet speed becomes slow.
At the same time, when the piston is retracted, the force for compressing the recoil spring 14 can be reduced. Therefore, if the retraction is performed with the same force, the retreat speed becomes faster, and the firing cycle becomes faster.
On the other hand, when the position of the adjuster 13 is advanced, the recoil spring 14 is compressed accordingly, and a series of operations starts. Therefore, the forward speed of the piston becomes faster due to the increase in the repulsive force of the recoil spring 14, and the flow speed at which the air in the cylinder is sent to the barrel becomes faster, so that the bullet speed is also increased.
At the same time, the resistance when the piston is retracted increases as the recoil spring 14 is compressed, resulting in a slower series of firing cycles.
From the above, it is difficult to understand the difference in single shot, but it becomes remarkable when fired continuously. The adjuster 13 can be applied to all toy guns that use the recoil spring 14, such as a gas blowback air gun and model guns.

In this embodiment, a large space can be secured on the outer periphery of the spring guide 22, and the adjustment range of the repulsive force of the recoil spring 24 can be made larger.

FIG. 9 shows a fifth embodiment of the recoil spring repulsive force adjustment mechanism in the toy gun of the present invention. In this embodiment, a case where a recoil spring is arranged between a spring guide arranged in the piston and a spring guide arranged in the rear part of the barrel will be described.
The recoil spring repulsive force adjustment mechanism 61 in the toy gun of the present embodiment is disposed at the rear part of the barrel 62 and a rod-shaped spring guide 64 disposed in the piston 63 disposed in the cylinder 68 in the barrel 62 shown in FIG. The present invention is applied to a toy gun including a recoil spring 66 disposed between the auxiliary spring guides 65.
In the recoiling spring repulsive force adjusting mechanism 61 in the toy gun according to the present embodiment, a rod-shaped spring guide 64 is disposed inside the piston 63, and the length of the spring guide 64 extends along the outer periphery of the spring guide 64. A large-diameter plate adjuster 67 is attached so as to be able to advance and retreat, and is engaged with the recoil spring 66. Therefore, the repulsive force of the recoil spring 66 can be adjusted by moving the plate adjuster 67 forward and backward.
FIG. 9 shows an example in which the recoil spring repulsion adjustment mechanism according to the second embodiment is applied and arranged in front of the recoil spring. The recoil spring repulsion adjustment mechanism of the other first embodiment and third to fourth embodiments can also be arranged in the piston, that is, in front of the recoil spring.

FIG. 11 shows a sixth embodiment of the recoil spring repulsion adjustment mechanism in the toy gun of the present invention.
The recoil spring repulsive force adjustment mechanism 71 in the toy gun of the present embodiment is disposed on the outer periphery of a spring guide 73 attached to the rear part of the barrel 72 shown in FIG. In addition, the present invention is applied to a toy gun including a recoil spring 76 disposed between a block-shaped guide 75 that pushes out a movable portion (bolt portion) B in an engine portion K in front of the movable portion B. Reference numeral 78 denotes a pressing screw that can move forward and backward in the spacer 79 disposed at the rear portion of the spring guide 73.
In the drawing, the recoil spring repulsion force adjusting mechanism of the second embodiment is already arranged, but instead, the recoil spring repulsion of the first embodiment, the third embodiment to the fourth embodiment is used. It is also possible to arrange an adjusting mechanism.
Furthermore, the position of the recoil spring repulsive force adjusting mechanism itself can be advanced and retracted by changing the front and rear length of the spacer 79 by exchange or by changing the total length of the pressing screw 78. Thus, by adding the “spacer” mechanism to the structures of the first embodiment, the third embodiment to the fourth embodiment, the repulsion force of the recoil spring 66 can be finely adjusted from the outside. Further, the function adjustment from the outside can be performed by exposing a part of the rear end of the spring guide portion of the first embodiment, the third embodiment to the fourth embodiment, or by linking the function with a spacer or a pressing screw. Can also be possible.

The form of 4th Example of the repulsive-spring repulsion force adjustment mechanism in the toy gun of this invention is shown to FIGS. 12-15 as an example of mounting | wearing.
FIG. 12 shows that the spring guide 83 (including the adjuster) of the recoil spring repulsion adjustment mechanism in the toy gun according to the fourth embodiment is in the forward state, and the piston 85 is in the forward state. In the figure, 82 is a space provided behind the barrel, 84 is a guide base, and 84 a is a male screw portion of the guide base 84.
FIG. 13 shows a state where the piston 85 of FIG. 12 is retracted. At this time, the recoil spring 81 is compressed.
FIG. 14 shows that the spring guide 83 is in the retracted position by adjusting the adjuster, and the piston 85 is in the advanced state. The repulsive force of the recoil spring 81 is weak compared to the state shown in FIG.
FIG. 15 shows a state where the piston 85 in FIG. 14 is retracted. In this case, since the recoil spring repulsive force adjustment mechanism is retracted, the repulsion force of the recoil spring 81 is weaker than in the case of FIG. 13 even if the piston is retracted.
In each of the above-described cases, even though the recoil spring (or piston spring) itself has the same capability, the operation performance performed by the spring can be made variable by the added structure.

(Operation)
The operation of the recoil spring repulsive force adjustment mechanism 61 in the toy gun of the present invention will be described below with reference to FIG.
A. When the trigger 91 is pulled, the power unit is activated, and the piston 63 is moved rearward via a lower gear 93 installed at the lower outer periphery of the piston 63.
B. At a certain position, the linkage between the piston 63 and the power gear 92 of the power unit is released, and the recoil spring 66 is released because it has been compressed by the retreat of the piston 63 until immediately before, and the piston 63 is pushed back in the cylinder 68 forward. . At that time, the air inside the cylinder 68 is compressed and sprayed into the gun cavity 94 to fire the BB bullet.
In the above series of operations, the recoil spring 66 is compressed by the retraction of the piston 63. Then, after the linkage is cut off, it is extended. This process does not change its ability unless the recoil spring 66 changes.
In the present invention, a positioning adjuster 67 is installed in front of the recoil spring 66, and by changing the position of the adjuster 67, the force for pressing the recoil spring 66 is variable.
This also changes the forward speed of the cylinder 68, and as a result, the bullet speed and the cycle of forward / backward movement of the cylinder 68 are made variable.

In the present invention, it becomes possible for the user to adjust to a product that meets the user's needs that could not be achieved by conventional products, such as a change in firing cycle, a change in bullet velocity, and an improvement in the elasticity of collection.
Of course, the scope of application of the present invention is not limited to the mechanisms and uses of the embodiments.
