Abstract

PURPOSE: To simplify the coupling mechanism while reducing leakage of gas by fitting a pipe connected with an inner magazine airtightly to a bullet feed pipe, enlarging the forward end of the connecting pipe by the forward end of the bullet feed pipe thereby feeding the bullets sequentially from the inner magazine to a bullet charging member. CONSTITUTION: When a pipe 28 connected with an inner magazine 7 charged with bullets 11 is fixed to a bullet feed pipe 25 at a machine section 4, the inner wall of a connecting member 28c and the outer wall of the bullet feed pipe 25 are held airtightly through an O-ring and gas is not leaked to the outside even if gas pressure spreads through the opening 13 of the machine section 4 into the inner magazine 7. A shopper 30 provided at the forward end of the tubular member 28a of the connecting pipe is released through action of the pipe 25 and a slit 29 and the bullets 11 can be fed constantly to the machine section 4. When the connecting pipe 28 is removed from the bullet feed pipe 25, the forward end of the tubular member 28a shrinks resiliently to block launching of the bullet 11 from the inner magazine 7.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a toy gun, specifically a toy gun that fires bullets using gas pressure, in which an inner magazine loaded with bullets is placed in a mechanical part formed inside the gun body. This invention relates to a toy gun that can be detachably attached via a connecting tube.

[Conventional technology]

Many toy guns have been proposed, such as Japanese Patent Application Laid-Open No. 173099/1983, which utilize gas pressure to fire a bullet by pulling a trigger.

Most of these known toy guns have an opening in the side wall of the engine part formed at the base of the barrel, a magazine containing a large number of bullets in a row is connected to this opening, and the trigger is pulled. Gas pressure is applied from behind the leading bullet that has been made to exist in the engine part, and the bullet is fired, and the bullet is propelled into the space inside the engine part created by the single shot, using the force of a spring placed inside the magazine. It has a structure in which one bullet is fed into the engine part and fired one after another. 2 For example, as shown in FIG. This connecting pipe 5
0, an inner magazine 7 is connected to the lower end thereof, and a distal end portion of a connecting tube 51 having a slider ring 56 fitted thereon is removably connected to the inner magazine 7.

The connecting pipe 51 has a concave groove in the outer circumferential wall of its head 52, an O-ring 53 is fitted into the concave groove, and a ring-shaped bushing 54 and an O-ring 55 are mounted on the lower part of the concave groove. A small hole is bored in the tube wall above the tube 51, and a steel ball 60 is fitted into this small hole, so that a part of the steel ball 60 is exposed inside the connecting tube 51 by the movement of the slider ring 56. It is configured.

A slider ring 56 that is mounted on the outside of the connecting pipe 51 so as to be vertically movable has an enlarged diameter part on the inside of the upper part into which a bush 54 and an O-ring 55 are fitted, and an O-ring 58 on the inside of the lower part.
and an enlarged diameter portion into which the bushing 59 is inserted, and the lower bushing 59 is always held by a spring 61 interposed between the bushing 59 and a stopper 62 fixed to the outer wall of the inner magazine 7 with a set screw 63. The outer wall of the connecting tube 51, which is pressed upward and includes the steel ball 60, is held airtight by upper and lower O-rings 55 and 58.

Thus, when the slider ring 56 mounted above the connecting tube 51 provided at the tip of the inner magazine 7 is not inserted into the connecting tube 50, the biasing force of the spring 61 causes the bushing 59 to close. The slider ring 56 and the bushing 54 are pushed upward together with the O-rings 54 and 58, and the bushing 54 comes into contact with the lower end of the head 52 of the connecting pipe 51 and stops rising. The reduced diameter portion 57 moves to the steel ball 60 portion of the connecting pipe 51 and presses the steel ball 60, acting so that a part of the steel ball 60 protrudes into the inside of the connecting pipe 51, and inside the inner magazine 7. A spring (not shown) prevents the bullet 11, which is constantly pressed upward, from escaping.

In addition, when the head 52 of the connecting pipe 51 is pushed into the connecting pipe 50, 1
As shown in the figure, the tip of the connecting pipe 50 presses the bush 54 against the biasing force of the spring 61 and pushes down the slider ring 56, so that the steel ball 60 is not exposed inside the connecting pipe 51 and slides into the slider ring 56. The bullet 1 in the connecting tube 51 is held in a protruding state within the gap between the ring 56 and the connecting tube 51.
1 is.

The steel ball 60 allows it to move freely toward the engine section 4 without being obstructed by the steel ball 60, and maintains a ready response to two firings.

Note that the connecting pipe 51 is removed from the connecting pipe 50.

When loading the bullet 11 into the inner magazine 7,
Connecting pipe 51 to inner magazine 7. slider ring 5
With the steel balls 60 attached, insert one bullet into the head 52 of the connecting tube 51. At this time, push down the slider ring 56 by hand to release the protrusion of the steel balls 60 into the inner surface of the tube. After inserting a predetermined number of bullets, the slider ring 56 is released from the press, and the steel balls 60 protrude into the connecting pipe 51 to prevent the bullets 11 from flying out.

In this state, the inner magazine 7 can be carried freely.

[Problem that the invention seeks to solve]

In the toy gun having such a structure, when nine bullets are fired, gas pressure for firing the bullets is applied to the engine section 4, and this also spreads into the inner magazine 7 through the connecting pipe 51.

That is, a small hole for holding the steel ball 60 is bored in the connecting pipe 51, and gas escapes to the outside through this small hole.

Therefore, in order to prevent gas from leaking to the outside from this small hole, the known toy gun has a slider ring 56 attached to the connecting pipe 51. O-rings 55 and 58, bushings 54.5
9, and a stopper 62. It has an extremely complex structure using a large number of small parts such as the spring 61.

Therefore, it cannot be denied that manufacturing and assembling these parts is not only extremely troublesome, but also has a considerable effect on increasing the cost of manufacturing toy guns.

In addition, most of these parts are assembled as individual parts, rather than being connected in one direction, and in particular, precise sliding and fitting are carried out to prevent gas from leaking from inside the engine section 4. Many complicated mechanisms are used to maintain airtightness, but even with these mechanisms, there is no possibility of gas leaking from the parts that come in contact with them.

It cannot be said that the disadvantages that hinder the effective use of gas as an energy source for projectile firing have been completely eliminated.

[Means for solving problems]

In view of the current situation, this invention was developed as a result of numerous research tests, and was developed as a toy that simplifies the connection mechanism between the engine part of the gun body and the inner magazine loaded with bullets, and prevents the gas used from leaking to the outside unnecessarily. The gun was developed.

Specifically, the present invention provides a toy gun having a structure that fires a bullet in response to gas pressure, in which an opening is formed in a part of the side wall of the engine section provided in the gun body, and an opening is formed through which the bullet is inserted. Along the opening edge of this opening, a bullet supply tube is provided which is covered with an O-ring and whose opening end is tapered. The inner circumferential surface of the part is a tapered surface that comes into sliding contact with the tapered surface at the tip of the bullet supply tube to form a stopper for preventing the movement of the bullet inside the cylinder, and a plurality of stoppers are formed along the axial direction from the edge of the opening. A cylindrical connecting member having an inner diameter that is approximately the same as the outer diameter of the bullet supply tube is placed on the upper outer circumferential surface of the cylindrical member provided with the slit, and the distal end surface thereof is connected to the distal end surface of the cylindrical member. The opening of the connecting member of this connecting tube is attached to the outer periphery of the bullet supply tube, and the tapered surface of the tip of the two bullet supply tubes is connected to the connecting tube. When the cylindrical member is press-fitted into the cylindrical member while making sliding contact with the tapered surface at the tip of the cylindrical member, the diameter of the cylindrical member's tip expands to feed the bullets in the inner magazine to the engine through the bullet supply pipe. When the connecting tube is removed from the bullet supply tube, the tip of the cylindrical member constituting the connecting tube is reduced in diameter to its original state, and the stopper protrudes into the cylindrical member, This toy gun is characterized in that it is configured to prevent the bullets in the inner magazine from moving from the connecting pipe to the bullet supply pipe side.

Further, the bullet supply pipe 2 is provided with a connecting pipe 28 in the engine section 4.
5, the tip of the cylindrical member 28a contracts in diameter due to its elasticity, and the stopper 30 protrudes into the cylinder.
This prevents the bullet 11 from flying out from the inner magazine 7.

Note that in order to fill the empty inner magazine 7 with two bullets 11, the connecting pipe 28 is pulled out from the bullet supply pipe 25,
The bullets 11 are sequentially pushed through the opening 31 of the connecting member 28c.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A toy gun 1 of the present invention is shown in FIG.

Basically, the engine part 4 houses the gun barrel member 39 and the bullet loading member 5. Reading body 2, which is equipped with a gas supply valve 15. trigger 1

The gun barrel member 3 is composed of a pipe member, and is disposed so as to loosely pass through a notch in a fixing plate 6 provided on the distal end side of the reading body 2 so as to be slidable in the axial direction.
Therefore, its base end is located in the vicinity of the opening 13 behind the initial end of the enlarged diameter stepped portion 14 formed inside the tip of the engine section 4, which will be described later.

The engine part 4 is formed of a vibrator member, and as described above, the inner circumferential surface near the tip part has an enlarged diameter step part 14 whose diameter increases toward the tip part.
A bullet loading member 5 that slides in the axial direction while being guided by a pin 12 protruding within the two engine parts 4 is installed inside.

This bullet loading member 5 is always urged in the direction of the gun barrel member 3 by a spring 9 having a weaker urging force than the spring 8, and its tip end is located at the position of the opening 13 formed in the engine part 4 at the muzzle of the gun. It is in contact with the proximal end of the barrel member 30 via the O-ring 10 on the side and rearward of the initial end of the enlarged diameter stepped portion 14 .

The opening 13 consisting of a hole with a diameter sufficient for one bullet to pass through is formed in the side wall located on the lower side of the engine section 4, and a cylindrical bullet supply pipe 25 is provided along the edge of the opening. As is clear from FIGS. 2 to 4, the bullet supply tube 25 is integrally provided with an outer diameter extending from the base of the two engine parts 4 at an appropriate distance through a step. As the diameter is reduced, an O-ring 26 is fitted into a groove formed on the outer wall of this reduced-diameter portion, and the outer wall of the opening at its tip is shaved off at an appropriate angle to form a tapered surface 27. in.

It communicates with the inside of the engine section 4 via the opening 13.

This bullet supply pipe 25 is connected to a connecting pipe 28 having an inner magazine 7 at one end, and a bullet loading member 5 slidably provided in the engine section 4 receives bullets 1 from the inner magazine 7. It is configured to always stop at the receiving position.

The inner magazine 7 is composed of a cylindrical body made of metal or synthetic resin material, the inner diameter of which is approximately the same as the outer diameter of the bullet to be used, and a spring (not shown) is provided at the bottom. It is configured to constantly push the filled bullets 11 upward, and is stored in the upper first magazine 24 which is connected to the bullet supply pipe 25 via the connecting pipe 28.

On the other hand, the connecting pipe 28 fitted onto the bullet supply pipe 25 is
The entire body is integrally molded from a synthetic resin material such as nylon that has appropriate elasticity and resilience against distortion, is wear resistant, and has excellent dimensional stability, and has an inner diameter that is the same as the inner diameter of the inner magazine 7. The tip of the inner magazine 7 is screwed into the base end of the cylindrical member 28a having
The inner circumferential surface of the tip thereof is a tapered surface 28b that makes sliding contact with the tapered surface 27 at the tip of the bullet supply tube 25, and a hook-shaped stopper 30 for preventing movement of the bullet 11 is provided in the tip of the cylindrical member 28a. A plurality of slits 29 are provided along the axial direction from the edge of the opening, and a tapered surface 28b at the tip of this cylindrical member 28a and the bullet supply pipe 25 are provided.
When the tapered surface 27 at the tip of the cylindrical member 2 comes into contact with the
The distal end of the cylindrical member 8a is configured to expand in diameter, and the upper outer circumferential surface of the cylindrical member 28a has a bullet supply tube 25 with an inner diameter.
A cylindrical connecting member 28C having an inner diameter slightly larger than the outer diameter of the reduced diameter portion, which is covered with an O-ring 26, is integrally formed with its distal end surface protruding from the distal end surface of the cylindrical member 28a. attached to.

Therefore, the connecting member 28'C that constitutes the connecting pipe 28
When the opening 31 is inserted along the reduced diameter portion of the bullet supply tube 25, the connecting member 28c is securely connected to the reduced diameter portion of the bullet supply tube 25 via the O-ring 26, as shown in FIG. At the same time, the tapered surface 27 at the tip of the reduced diameter portion and the tapered surface 28b at the tip of the cylindrical member 28a come into contact, and the tip of the reduced diameter portion is press-fitted into the tip of the cylindrical member 28a.
The tip of the cylindrical member 28a is expanded by the slit 29,
A through hole is formed between the inner magazine 7 and the bullet supply pipe 25 that is sufficient to allow the bullets 11 to pass through without the stopper 30 protruding inward.

Note that when the connecting tube 28 is pulled out from the bullet supply tube 25 while the inner magazine 7 is attached, the connecting tube 28 is removed as described above.
The engagement between the distal end of the cylindrical member 28a constituting the bullet supply tube 25 and the reduced diameter portion of the bullet supply tube 25 is released, the distal end of the cylindrical member 28a is reduced in diameter to its original state, and the stopper 30 protrudes into the bullet path. This prevents bullets 11 from escaping within the inner magazine 7.

The O-ring IO made of an elastic material is disposed between the gun barrel member 3 and the bullet loading member 5 of the reader body 2.

Its inner diameter is slightly narrower than the diameter of the bullet 11.2 When the bullet loading member 5 is in the bullet loading position, it is located closer to the muzzle than the opening 13 formed in the engine section 4, and is located at the beginning of the enlarged diameter stepped portion 14. By contacting the base end of the gun barrel member 3 at the rear of the end position and preventing the bullets 11 from moving toward the muzzle side when the bullets 11 from the inner magazine 7 are loaded into the bullet loading member 5, This prevents the next bullet 11 from moving into the barrel member 3.

As shown in FIG. 1, a gas supply valve 15 is provided in the reader body 2 at the rear of the engine section 4 having the above structure.
.

The gas supply valve 15 is equipped with a valve body 16 that is always closed by the biasing force of a spring 17, and low-pressure fluorocarbon gas supplied from a gas cylinder (not shown) through a gas tube 18 is supplied into the engine section 4. Preventing it from being sent.

A trigger 19 provided on the reading body 2 is linked to the gas supply valve 15 via a cam member 21 having two arms.

That is, when the trigger 19 is pulled against the biasing force of the spring 20, the cam member 21 that interlocks with the trigger 19 is activated, and one arm of the cam member 21 applies the biasing force of the spring 17 to the valve body 16. Since it is configured to open the gas supply valve 15 by lifting it upwards against resistance, when the trigger 19 is pulled, the fluorocarbon gas from the gas cylinder is ejected into the engine section 4 and the 9 bullets 11
It is configured to apply gas pressure to the back of the

When gas pressure is applied behind the two bullets 11 by operating the trigger 19, the gas pressure (usually 6 to 7 atmospheres) is stronger than the biasing force of the spring 8, so the gas pressure causes the bullets 11 to move toward the bullet loading member 5. At the same time, it is pushed toward the muzzle.

Note that the next bullet 11 is prevented from entering the first engine section 4 by the movement of the nine bullet loading member 5 toward the muzzle.

As a result, the 0 ring 10 was blocking the movement of the 2 bullets 11.
moves to the muzzle side at the same time, and the gun barrel member 3 also moves to the muzzle side, but the enlarged diameter step part 14 is formed in the distal end of the engine part 4, and the ring 1o is made of an elastic material. When the O-ring 10 reaches inside the diameter-expanding stepped portion 14, the O-ring 10 expands in diameter due to the pressure received from the spherical surface of the bullet 11.
The bullet 11 is pushed beyond the O-ring IO into the gun barrel member 3, and is ejected from the muzzle by the gas pressure.

When the bullet 11 is fired, the gas pressure disappears, and the barrel member 3 returns to its original bullet loading position due to the action of the spring 8 against the biasing force of the spring 9, so that the O-ring 10 also returns to its original position. After returning, new bullets 11 from the inner magazine 7 are supplied to the bullet loading member 5 in the engine section 4 through the connecting pipe 289 and the bullet supply pipe 25.

In the figure, 22 is the stopper of the trigger 19, 23 is the grip,
32 indicates a threaded portion between the inner magazine 7 and the connecting pipe 28.

〔Effect of the invention〕

In the toy gun of the present invention, an opening for inserting a bullet is formed in a part of the side wall of the engine section of the reading body.

A bullet supply pipe is connected to this opening, and separately, a distal end of an inner magazine is attached to the base end, and the inner peripheral surface of the distal end is slidably connected to the tapered surface of the distal end of the bullet supply pipe. A stopper for preventing the movement of the bullet is formed in the cylinder as a contacting tapered surface, and a plurality of slits are provided along the axial direction from the edge of the opening on the upper outer peripheral surface of the cylindrical member. forming a connecting tube in which a cylindrical connecting member having an inner diameter approximately the same as the outer diameter of the bullet supply tube is provided concentrically with its distal end surface protruding from the distal end surface of the cylindrical member; This connecting tube can be detachably attached to the bullet supply tube.

Therefore, when the connecting tube is attached to the bullet supply tube, an O-ring is interposed between the inner wall of the connecting member constituting the connecting tube and the outer wall of the bullet supply tube to keep them secret, and the gas is kept in the engine. A tube that prevents gas from leaking out from the engine section even if it flows out to the inner magazine side from the opening for bullet insertion provided in the section, and that forms a connecting member by the tip of the bullet supply tube. Expand the diameter of the tip of the shaped member.

The operation of the stopper for preventing the movement of the bullets protruding into the cylindrical member is released, and the bullets can be smoothly supplied from the inner magazine to the engine section.

On the other hand, when the connecting tube is removed from the bullet supply tube connected to the engine part, the diameter of the tip of the cylindrical member constituting the connecting tube is automatically reduced, and the stopper formed at the tip of the cylindrical member protrudes into the cylinder and prevents bullets from ejecting from the inner magazine.

In addition, the toy gun of the present invention can be attached and detached from the two engine parts and the in-mar magazine with a single touch, and there is no leakage of gas from the connection part, so that the gas for firing bullets can be used effectively. In addition, compared to the conventional mechanism for connecting the engine part of a toy gun and the inner magazine, the number of connecting components can be kept to a minimum, which significantly reduces the cost of making a 9-part mold. This has many advantages, such as the fact that the toy gun can be assembled with great ease and the productivity of the toy gun can be greatly improved.
