Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toy gas gun, and more particularly to a hop-up device for imparting rotation to a spherical bullet (BB bullet) to extend a range, and particularly to a revolver toy gas gun. The present invention relates to an improvement for incorporating a hop-up device with a simple structure without impairing the identity with the design of a real gun.

[0002]

2. Description of the Related Art A toy gas gun uses a compressed gas such as Freon gas injected into a gas accumulator to fire a BB bullet. In that case, the valve provided on the nozzle side is momentarily opened to supply the compressed gas to the back of the BB bullet to fire the BB bullet, but since the BB bullet has a spherical shape, it is fired with almost no rotation. The length of the range is determined by the initial velocity given by the pressure and the air resistance after the launch.

Therefore, if the gas pressure is increased, it is possible to extend the range, but in the toy gas gun, the gas pressure is limited to prevent danger, and the range is naturally limited. is there. However, from the viewpoint of users of toy gas guns, it is inevitable that the toy gas gun has a long range.

Therefore, it has been conventionally devised that the upward rotation (backspin) is forcibly given to the BB bullet at the time of launching, thereby giving a lift force by Bernoulli's theorem to extend the range, The device is generally called a hop-up device in the field of gas guns and pneumatic guns.

Regarding the above-mentioned hop-up device, various proposals such as Japanese Utility Model Laid-Open No. 63-179490 and Japanese Patent Laid-Open No. 6-3091 have been made. First, in Japanese Utility Model Laid-Open No. 63-179490 (a trajectory adjusting device for an air toy gun), a hop-up device as shown in FIG. 9 is proposed. According to this device, the ballistic adjusting member 103 is provided between the pump head 101 and the barrel 102,
A rubber cylindrical portion 104 is fitted inside the member 103, and a screw 105 screwed into the member 103 from above.
Thus, a part of the rubber cylindrical portion 104 can be pushed inward. Therefore, the BB bullet 106 sent into the rubber cylindrical portion 104 as the bullet holding portion goes straight inside the rubber cylindrical portion 104 toward the barrel 102 side when compressed air is supplied to the back, but in the process. BB bullet 10
6 collides with the pushed-in portion of the rubber cylindrical portion 104. As a result, a BB bullet 106 with a backspin
Will be fired through the barrel 102.

Japanese Unexamined Patent Publication No. 6-3091 (a hop-up device for a bullet in a toy gun) is shown in the exploded view of parts in FIG. 10 and the sectional view of the main part in FIG. 11, and a mechanism shown in FIG. 12 is also proposed. ing. Specifically, an opening 113 that communicates with the inside is provided on the upper surface of the gun cavity 112 that fires the BB bullet 111, and
A cylindrical friction member 114 made of an elastic material having a friction coefficient larger than that of the inner wall surface of 12 covers the outside of the opening 113, and a pressing member 115 elongated in the moving direction of the BB bullet 111 is arranged in the opening 113. By pressing the friction member 114 into the gun cavity 112 via the pressing member 115, the upper portion of the BB bullet 111 is brought into contact with the friction member in a predetermined section.

A friction adjusting mechanism for variably adjusting the degree of friction is provided for the pressing member 115. As shown in FIG. 10, the friction adjusting mechanism is composed of a movable portion 116, a handle portion 117, and a holding portion 118. The movable part 116 is a cylindrical part 119 that fits inside the barrel.
And a rod-shaped cam member 120, and a rack 121 is formed in the cylindrical portion 119 inside a long hole formed in the side portion thereof. A pinion 122 is formed on the handle 117, and the pinion 122 meshes with the rack 121 through a hole formed in the outer casing. The holding portion 118 has the pressing member 1 on the upper side thereof.
A hole 123 into which the cam member 15 is fitted is formed, and a guide frame 124 through which the cam member 120 is inserted before and after the hole 123.
Are formed.

Therefore, according to this friction adjusting mechanism, when the handle portion 117 is rotated, the movable portion 116 moves back and forth as shown in FIG. 11, and the pressing amount of the pressing member 115 is adjusted by the cam member 120. Therefore, it is possible to adjust the amount by which the friction member 114 in the region of the opening 113 of the gun cavity 112 is expanded into the gun cavity 112. In the hop-up device, unlike the above-mentioned No. 63-179490, the muzzle 11
In order to swell the friction member 114 only to the upper side in 2,
It is possible to give a large frictional resistance to the BB bullet 111 only on the upper side. That is, the backspin can be given more efficiently, and the power loss during the firing operation can be minimized.

In the hop-up device shown in FIG. 12, the pressing member 126 can be pushed down by the rotation of the eccentric cam 125 without using the rod-shaped cam member as described above in the cam mechanism. Therefore, the size of the device can be reduced, and the structure of the holding portion 127 is simplified.

[0010]

As described above, the hop-up device is an additional function that is attractive to the users of gas guns and pneumatic guns, and a large number of those having an adjusting mechanism are commercially available. As described above, the means for bulging a part of the friction member into the gun cavity is by means of a screw screwed on the upper side of the barrel or by a cam mechanism, and inevitably there is a screw or handle on the outside of the gun body. It will be configured in an exposed manner.

On the other hand, in the case of a toy gun, it is strongly required that the design of the toy gun is the same as that of the corresponding real gun. Therefore, it is good to provide the hop-up device as described above, but it is not preferable that the design is different from that of the real gun due to this, and it is required that the adjusting mechanism and the like do not affect the appearance. .

In particular, in a revolver gun, the design of other shotguns, rifles, and handguns differs greatly depending on the model, but the basic form is relatively uniform, so it is a small additional element. But it is easily noticeable. For example, a revolver type gas gun can be used with
When the No. hop-up device is applied, the screw will protrude on the body frame and the upper part of the barrel, and even if you do not project from the barrel using a screw without a head, the screw hole Will be exposed to. In addition, JP-A-6-3
The 091 hop-up device is not suitable for revolver-type gas guns because the cam mechanism is exposed outside.

Therefore, the present invention was created for the purpose of constructing a hop-up device in a revolver type toy gas gun that can be adjusted in such a manner that the mechanical elements are not exposed to the outside.

[0014]

According to the present invention, in a revolver type toy gas gun, at least the side of the inner fitting mounting portion of the barrel with respect to the main body frame facing the cylinder of the main body frame from the feed holder of the cylinder. As a double structure consisting of a barrel tube that guides the ejected spherical bullet forward and a barrel body that is externally fitted to the barrel tube and internally fitted to the body frame, the barrel tube has a hole in the upper part thereof. (Hereinafter referred to as “first hole”) is formed, while
A hole having a diameter smaller than that of the first hole (hereinafter referred to as "second hole") is formed at a position corresponding to the first hole in a direction substantially perpendicular to the cylinder axis, and the second hole is formed from a surface facing the cylinder. The screw hole communicating with the cylinder axis is formed in a direction substantially parallel to the cylinder axis, and a recess having a planar shape larger than the first hole is formed at the position where the second hole is formed on the inner peripheral surface. Based on the above, the elastic friction member in which the plate portion that fits into the concave portion and the short column portion that fits into the first hole are integrally formed with respect to the constituent portions of the concave portion and the first hole is loaded, The present invention relates to a hop-up device for a revolver toy gas gun, wherein a hard ball is fitted into the second hole and a sharpened set screw is screwed into the screw hole.

According to the present invention, when the setscrew screwed into the cylindrical body is rotated to increase the screwing amount, the lower tapered surface of the set screw is fitted into the second hole. The sphere presses downward, and the hard sphere presses the lower elastic friction member. The plate portion of the elastic friction member is interposed in the concave portion between the barrel tube and the barrel body, but since the diameter of the hard ball in the second hole of the barrel body is smaller than the first hole of the barrel tube, The elastic friction member is bent to project the short column portion from the inner peripheral surface of the barrel tube. Therefore, in this state, the BB bullet ejected by the gas pressure from the cylinder side comes into contact with the short column portion of the elastic friction member in the process of advancing in the barrel tube, and back spin is applied to the BB bullet. On the other hand, when the screwing amount of the setscrew is reduced, the lower tapered surface of the sharp point retracts, so the hard sphere moves upward due to the restoring force of the elastic friction member, and the short column portion of the elastic friction member also retracts upward. To do. As a result, by adjusting the screwing amount of the set screw, the contact state between the BB bullet and the short column portion can be adjusted, and the strength of the hop-up function can be adjusted.

By the way, the hop-up device of the present invention is configured as an internal fitting mounting portion of the barrel to the main body frame, and any element therefor is not exposed to the outside. The rear end surface of the cylindrical body is exposed on the cylinder side surface of the main body frame, but the same surface is hidden by the loading of the cylinder. Therefore, according to the present invention, it is possible to construct a revolver toy gas gun incorporating a hop-up device having a simple structure while making the design completely the same as that of a real gun.

In the above invention, if a set screw having a square hole is applied, the set screw can be rotated by a square bar wrench with the cylinder removed from the cylinder loading portion of the main body frame. Will be easier.
Further, if the distance from the cylinder at the position where the backspin is applied to the BB bullet is changed, the flight speed of the BB bullet and the strength of the hop-up effect are contradictory, but the flight mode of the BB bullet can be changed. In the present invention, the barrel tube and the barrel are detachably attached to the barrel and the main body frame, respectively, and the barrel tube and the barrel having different formation positions of the first hole and the second hole are prepared as optional parts. By doing so, it is possible to realize various flight modes of BB bullets simply by exchanging those parts, and to expand the way of enjoying the gas gun.

The elastic friction member is generally made of rubber, but may be made of resin having a large friction coefficient and elasticity. As the hard balls, steel balls or resin balls having high hardness can be used.

[0019]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 8. First, FIG. 1 is a cross-sectional view of a main part of a revolver toy gas gun to which the hop-up device according to the embodiment is applied. 1 is a main body frame, 2 is a grip, 3 is a cylinder, and 4 is a barrel. Here, the cylinder 3 is composed of an outer drum portion 11 and an inner fixing portion 12, and is configured so that only the appearance resembles that of a cylinder of a real gun. It is designed to be removable. The drum portion 11 is provided with six bullet feed holding portions 14 for the BB bullets 13 in the circumferential direction on the front surface thereof, and a cam mechanism (not shown) that interlocks with the operation of pulling the hammer 1a of the main body frame 1 rearward. ) To rotate the bullet holding unit 14 so that it is positioned on the axis of the barrel 4. On the other hand, the fixed portion 12 has a gas accumulating chamber 15, a valve 16 and a valve opening / closing mechanism (not shown) built therein, and the valve opening / closing mechanism is a cam mechanism (not shown) that works together when the trigger 1b of the main body frame 1 is pulled. The valve 16 is momentarily opened via (1) to cause the compressed gas in the gas pressure accumulating chamber 15 to be ejected and supplied to the back of the BB bullet 13.

The barrel 4 of this embodiment comprises an outer cylinder 17 forming the outer appearance of the barrel, a fixing cylinder 18 for fixing the outer cylinder 17 to the body frame 1 side, and a firing passage for the BB bullet 13. It has a triple-tube structure including a gun tube 19 and a gun tube 19. Only the gun tube 19 is guided from the fitting portion of the fixing tube 18 to the main body frame 1 to the front of the cylinder 3.

The feature of this embodiment is that it is fitted in the barrel fitting hole 20 of the main body frame 1 between the fixing cylinder 18 and the front of the cylinder 3 in the barrel 4 and is attached to the barrel tube 19. It is fixed by interposing an externally fitted tubular body 21, and a simple hop-up device is incorporated within the thickness of the tubular body 21. At the rear end of the cylindrical body 21, the main body frame 1
A flange portion that engages with the
Is attached to the main body frame 1 by screwing a female screw portion formed on the inner surface of the rear section of the fixing cylinder 18 to a male screw section formed on the small diameter section of the front portion of the cylinder body 21.

The configuration of the hop-up device is
A detailed description will be given with reference to FIG. 1, which is an exploded view of parts, and FIG. 3, which is an enlarged cross-sectional view of essential parts, in addition to FIG. A barrel insertion hole 20 is formed in the axial direction of the barrel 4 on the front surface of the frame portion of the main body frame 1 into which the cylinder 3 is loaded, and the barrel 21 is fitted in the hole 20. A screw hole 31 is formed in the thickness of the upper part of the shaft in a direction parallel to the axial direction, and a hole 32 is formed in the direction perpendicular to the axial direction at a position at a constant distance from the rear end face. There is. Further, a recess 33 is formed on the inner peripheral surface of the cylindrical body 21 up to the rear end side in the circumferential width of the region including the hole 32. Further, the rear end side section of the gun tube 19 is fitted in the tube body 21, but at the position corresponding to the hole 32 on the tube body 21 side of the gun tube 19, the diameter of the hole 32 is smaller than that of the hole 32. A hole 34 that is large and smaller than the plane area of the recess 33 is formed.

Next, 35 is an elastic friction member made of rubber, and has a plate portion 35a curved in an arc shape and a short columnar projection portion 35b.
Is integrally formed, and the projection amount of the protrusion 35b is set to be equal to or less than the wall thickness of the gun tube 19 and the diameter is set so as to be fitted into the hole 32 on the gun tube 19 side. ing. 36 is a steel ball, which is fitted into the hole 32 of the tubular body 21. Further, 37 is a hexagon socket set screw with a sharp tip, which is screwed into the screw hole 31 of the cylindrical body 21.

Therefore, with the above structure and parts, the cylindrical body 2
The hop-up device 1 includes a main body frame 1 and a gun tube 19
Therefore, it is possible to assemble the structure as shown in FIG. Then, in the assembled state, the elastic friction member 35 fits the protrusion 35b into the hole 32 of the barrel tube 19, and the plate portion 35a is attached to the outer peripheral surface of the barrel tube 19 and the cylindrical body 2.
It is set so as to be interposed between the first concave portion 33 and the first concave portion 33, and the steel ball 36 is loaded between the upper surface of the plate portion 35a and the lower surface side of the sharpening point of the set screw 37.

By the way, FIG. 3 shows a state in which the hop-up function is not exerted, in which the steel ball 36 is only fitted in the above-mentioned position, and the elastic friction member 35 causes the steel ball 36 to plate the plate portion 35a. I just put it on the upper side of
The tip surface of the protrusion 35b is located at the same level as or slightly outside the inner peripheral surface of the gun tube 19. Therefore, even if the BB bullet 13 press-fitted into the bullet holding portion 14 goes straight forward in the barrel tube 19 due to the gas pressure, slight friction is caused over the entire circumference due to the relationship with the inner peripheral surface of the barrel tube 19. They only proceed while receiving on average, and are fired with almost no rotation.

On the other hand, FIG. 4 shows a state in which the hop-up function is exerted. In this case, the set screw 37 is rotated to set a large screw-in amount. Then,
By the forward movement of the set screw 37, the tapered surface of the tip thereof pushes the steel ball 36 downward, and the central portion of the elastic friction member 35 is pushed downward via the steel ball 36. , The plate portion 35a bends in a manner of bulging downward,
5b is in a state of protruding inward from the inner peripheral surface of the barrel tube 19.

In this state, when the BB bullet 13 is moved straight forward by gas pressure, the projection 35b of the elastic friction member 35 and the upper side of the BB bullet 13 come into contact with each other, and a large frictional force is exerted. Since the gas pressure on the BB bullets 13 continues to act even at this point in time, backspin is imparted to the BB bullets 13. Also, set screw 37
If the amount of screwing in is increased, the amount of downward movement of the steel ball 36 is correspondingly increased, and conversely, if the amount of screwing in of the set screw 37 is decreased, the restoring force of the elastic friction member 35 causes a corresponding return. The magnitude of the frictional force is set screw 37.
The amount of backspin applied (that is, the strength of the hop-up function) can be adjusted as appropriate.

The adjustment of the screw-in amount of the set screw 37 is made because the set screw 37 has a hexagonal hole as described above.
As shown in FIG. 5, this can be easily performed by inserting the hexagonal bar wrench 41 into the hexagonal hole of the setscrew 37 and rotating the hexagonal bar wrench 41 in a state where the cylinder 3 is laterally removed from the body frame 1.

It should be noted that this hop-up device can be constructed inside the cylindrical body 21 with an extremely simple and small-scale mechanism, and as shown in FIG. 6, a revolver toy gas to which the device is applied. It has no effect on the design of the gun. That is, when the device of Japanese Utility Model Laid-Open No. 63-179490 is applied, the screws and screw holes are exposed in the upper surface region (region 42 in FIG. 6) of the main body frame 1, which is very different from the actual gun. However, according to this embodiment,
It is possible to realize a revolver toy gas gun that has the same design as a real gun while incorporating a hop-up device.

In this embodiment, the set screw 37
The relationship between the screw-in amount and the bending amount of the elastic friction member 35 can be freely set by selecting the angle of the tip of the set screw 37. Specifically, in FIG. 7, when the angle θ of the sharp tip of the set screw 37 is selected to be 90 °, the set screw 37
The amount of screwing in a is equal to the amount of movement b of the steel ball 36 (corresponding to the amount of bending of the elastic friction member 35). Adjustment becomes easy.

Regarding the position of the gun tube 19 where the hop-up function is applied, the barrel 21 and the gun tube 19 are also selected.
It is possible to freely change the positions of the holes 32 and 34 by preparing optional parts having different positions in the front-rear direction. In that case, if the hop-up function is operated at a position closer to the cylinder 3 as in the above-described embodiment, a backspin due to friction is applied when the BB bullet 13 initially moves, and thereafter, the BB bullet 13 is continuously pushed out by gas pressure. In addition, the hop-up effect is a little weak, but the firing speed is relatively high. On the contrary, as shown in FIG. 8, if the distance d is set to be large and the hop-up function is operated at a position far from the cylinder 3, a strong backspin due to friction is applied when the BB bullet 13 is accelerated to some extent, Since the gas pressure pushes out at a shorter distance thereafter, the hop-up effect can be more remarkably exhibited although the firing speed is reduced. Therefore, just prepare some of the above optional parts and replace them,
It is possible to select the trajectory according to the taste. When the hop-up function is operated at a position distant from the cylinder 3, it is necessary to use a long set screw 37 as shown in FIG. 8, but set screws of various lengths are available as standard products. It is easy to obtain because it exists.

In the above embodiment, the barrel 4 is the outer cylinder 1.
Although it has a triple structure composed of 7, the fixing cylinder 18 and the gun tube 19, the outer cylinder 17 and the fixing cylinder 18 may be integrally formed. Further, even if the components other than the barrel tube 19 of the barrel 4 and the tubular body 21 are integrated, there is no particular problem in the configuration and assembly of the hop-up device, and such a configuration may be adopted.

[0033]

The hop-up device for a revolver type toy gas gun of the present invention has the following effects due to the above configuration. The invention of claim 1 makes it possible to incorporate a simple and small-sized adjustable hop-up device into a revolver toy gas gun without exposing its constituent elements to the outside.
