Description

Toy gun reversal generating mechanism

The present invention relates to a recoil generating mechanism for a toy gun, which is capable of causing a toy gun to generate a real gun-like recoil impact upon launch.

It is proposed in the prior art that there is a mechanism for generating a recoil (rear seat force) identical to that of a real gun when a BB bomb is fired using a toy gun. In the air gun described in Patent Document 1, for example, a barrel that is interlocked with a front end of a piston that moves forward and backward is provided, and a weight and a retracting spring are attached to the barrel. When the mechanism is launched, when the barrel advances along with the advancement of the piston, the weight and the retracting spring loosely engaged with the barrel are moved back and forth to generate a kickback mechanism.

On the other hand, the kickback generating mechanism described in Patent Document 2 replaces the barrel of Patent Document 1 with a transmission rod, and uses a transmission rod that interlocks with the reciprocating motion of the piston. A hollow portion is formed in the transmission rod, and a buffer rod and a buffer rod spring are further slidably disposed in the hollow portion. The above-described transmission rod moves the weight and the reentry spring to generate a kickback.

[Patent Document 2] Patent No. 4959838

The recoil generation mechanism of the prior art is all configured to move the weight or the reentry spring back and forth using a barrel or a transmission rod that is interlocked with the piston. Therefore, the position for arranging the weight or the recoil spring must be disposed at a position away from the organ portion in front of or behind the organ portion for providing the piston. As a result, the size of the toy gun having the recoil generating mechanism of the prior art is limited to a large toy gun.

For example, when the recoil generating mechanism is disposed behind the organ unit, the shoulder portion of the gun is used. Further, when the recoil generating mechanism is disposed in front of the organ unit, the long gun body is used for arrangement. As mentioned above, it is not possible to install a conventional recoil-producing mechanism for a large toy gun like a rifle. It is extremely difficult to install a small toy gun such as a rifle or a pistol without a shoulder rest.

Moreover, the kickback generated when the bullet is fired using a real gun is generated by the organ portion loaded with the bullet, but the recoil generating mechanism attached to the toy gun is configured to be located away from the organ portion where the piston is disposed. Move the weight to create a kickback. Therefore, the recoil generation mechanism of the prior art has the following disadvantages: it will form a feeling different from the impact of the backlash of the real gun.

The present invention has been developed in order to solve the above problems, and an object thereof is to provide a recoil generating mechanism for a toy gun, which is not only applicable to a compact toy gun which is extremely compact, but also can realistically restore a real gun to produce a recoil. s position.

The first means of the present invention disclosed in order to achieve the above object is characterized in that the piston cylinder device 1 is disposed in a body portion P of a toy gun and generates compressed air by a piston spring 2, and a weight 5 is provided. The reciprocating movement of the piston 3 of the piston-cylinder device 1 to move back and forth, and is a recoil generating mechanism for generating a kickback toy gun by the movement of the weight 5 interlocking with the piston 3 when the bullet Q is fired. The weight accommodating portion 3A is formed inside the piston 3, and the coil spring-shaped piston spring 2 is accommodated in the weight accommodating portion 3A, and the weight 5 is movably moved back and forth to the piston spring 2 Inside, the weight spring 5A is coupled to the rear of the weight 5 so that when the bullet Q is fired, the piston spring 2 causes the piston 3 to move toward the front end side of the cylinder 4 at a high speed, and the weight spring 5A follows the piston. 3 The weight 5 is pressed into the weight storage portion 3A and pushed, thereby generating backlash.

A toy gun which is the object of the present invention relates to a toy gun in which a piston cylinder device 1 is used to generate a recoil force. Therefore, the mechanism for driving the piston-cylinder device 1 is not limited to the electric motor type, and any mechanism such as a manual air compression method or a piston method using a fluid such as a gas can be selected.

The piston 3 of the present invention is selected from synthetic resin, aluminum, titanium, carbon fiber, magnesium, etc., and is relatively light in weight, and the material of the weight 5 is preferably a metal material having a weight. Further, the shape, material, weight, and the like of the weight 5 can be arbitrarily set. Further, the shape of the weight accommodating portion 3A for accommodating the weight 5 can be formed by a weight having a concave shape in which the rear end of the piston 3 is opened, or a space independent of the inside of the piston 3 and the surroundings. Part 3A or the like, the weight receiving portion 3A of an arbitrary shape.

The second means is configured such that a buffer body 6 is provided between the tip end of the weight 5 disposed in the weight accommodating portion 3A of the piston 3 and the front end side surface 3B of the piston 3, and the buffer body 6 is provided. To reduce the impact force of the aforementioned weight 5 when impacting. In addition to the linear coil spring or the tapered spring, the cushion body 6 may also be selected from a rubber material or a synthetic resin material, a bellows-shaped air cushion body, and an oil pad to reduce the impact force of the weight 5 when impacting. .

The third means is configured such that the piston spring 2 is disposed so as to be surrounded by the spring guide portion 7 provided in the mechanism portion P, and the spring guide portion 7 corrects the piston generated when the piston spring 2 is compressed. The bending of the spring 2 is deformed.

As described in the first aspect of the present invention, the weight accommodating portion 3A is formed inside the piston 3, and the piston spring 2 is housed in the weight accommodating portion 3A, and the weight 5 can be freely moved back and forth. Inside the piston spring 2, the weight spring 5A is coupled to the weight 5 At the rear, when the bullet Q is fired, the piston spring 2 moves the piston 3 toward the front end side of the cylinder 4 at a high speed, and causes the weight spring 5A to follow the piston 3 to press into the weight receiving portion 3A and push the weight 5 The structure of the recoil is generated, and it is possible to install only a small space in the organ. Therefore, it is possible to provide a recoil generating mechanism that can be mounted even if it is difficult to mount a conventional recoil generating mechanism, and can be applied to a toy gun of all sizes from the rifle to the pistol.

Further, since the weight spring 5A immediately follows the piston 3 that moves at a high speed in the mechanism portion P after the bullet Q is fired, and the weight 5 is pushed by the hammer 5, the backlash can be truly restored. Timing or location.

As described in the second aspect of the invention, the buffer body 6 is provided between the distal end of the weight 5 disposed in the piston 3 and the inner side surface 3B of the distal end portion of the piston 3, and the weight 6 is reduced by the buffer body 6. Impact force when impacting. In particular, it can withstand the severe use conditions such as electric air guns that repeatedly accelerate and retreat through the motor, and can effectively alleviate the strong vibration during impact. This result not only reduces the damage of various parts of the piston-cylinder device 1 and the like, but also reduces the uncomfortable impact feeling of the weight 5 when the impact is made, and can be obtained as when shooting with a real gun. Feel the feeling.

As described in claim 3, the piston spring 2 is disposed so as to be surrounded by the spring guide portion 7 formed in the mechanism portion P, and the piston spring generated when the compression piston spring 2 is corrected by the spring guide portion 7 2 bending deformation. Thereby, the correct telescopic movement of the piston spring 2 can be ensured Work. Therefore, when the weight 5 is advanced and the backlash is generated, when the piston spring 2 is compressed again, it can be compressed at a normal position, and the correct expansion and contraction operation of the piston spring 2 can be repeated.

According to the recoil generating mechanism of the present invention, it is possible to achieve the original object of the present invention: it can also be applied to a small toy gun such as a gun or a pistol which is extremely delicate in construction and does not have a shoulder rest, and truly restores the real gun. The location of the punch.

Hereinafter, embodiments of the invention will be described. In the recoil generating mechanism of the present invention, the piston-cylinder device 1 is disposed in the mechanism portion P, and is attached to a toy gun that generates compressed air by the piston spring 2. In the illustrated example, the body of the toy gun is omitted, and the body of the toy gun is omitted. However, the mechanism unit P is provided as a driving mechanism for a toy gun that simulates a rifle. Further, the drive mechanism of the mechanism unit P is not limited to the electric system of the drawings, and any mechanism such as a manual air compression method or a piston method using a fluid such as a gas can be selected.

In other words, the mechanism unit P of the present invention is a mechanism in which the weight accommodating portion 3A is formed inside the piston 3, and the piston spring 2 composed of the coil spring is housed in the weight accommodating portion 3A. Further, the piston cylinder device 1 generates compressed air by the pressing force of the piston spring 2. Further, inside the piston spring 2, the weight 5 is placed so as to be freely movable back and forth (refer to Fig. 1). The weight spring 5A is coupled to the rear of the weight 5. Further, when the bullet Q is fired, the piston spring 2 moves the piston 3 toward the front end side of the cylinder 4 at a high speed, and causes the weight spring 5A to follow the piston 3 to press in the weight receiving portion 3A and push the weight 5 This produces a backlash.

The recoil generating mechanism of the present invention is in the phase of the piston spring 2 After the relatively light piston 3 is moved at a high speed toward the front end side of the cylinder 4, the weight spring 5A is pressed and the relatively heavy weight 5 is pushed. When the above-described operation is performed, since the counterweight is generated when the weight 5 is moved in the weight accommodating portion 3A immediately after the projectile Q is fired by the piston 3, it is formed such that the backlash with the real gun can be generated from the organ portion P. Similar construction (see Figures 5 and 6).

In the weight accommodating portion 3A of the example of the figure, the member constituting the piston 3 has a rear end portion in the shape of a recess having an opening, and the front end of the weight 5 is formed as a front end side of the recessed portion. Insert in the direction (refer to Figure 2). The material of the piston 3 is a relatively lightweight material selected from synthetic resin, aluminum, titanium, carbon fiber, magnesium, and the like. Thereby, not only the piston 3 can be moved at a high speed but also the damage caused when the front end of the piston 3 collides with the cylinder 4 can be reduced. On the other hand, the material of the weight 5 is a metal material having a weight. Thereby, a greater backlash can be obtained. Further, the shape, material, weight, and the like of the weight 5 can be arbitrarily set.

Further, when the weight 5 hits the inner side surface 3B of the front end portion of the piston 3, the piston 3 or the cylinder 4 may be damaged (see Fig. 7). Here, the buffer body 6 is provided on the distal end side of the weight 5, and the shock absorber 6 reduces the impact force generated when the weight 5 is hit. In the buffer body 6 of the example of the drawings, a coil spring that protrudes from a concave portion at the tip end of the piston 3 is used (see Fig. 1). In addition, a linear spring accommodated in the groove portion, a rubber material, a synthetic resin material, a bellows-shaped air cushion body, an oil pad, or the like may be used as the buffer body 6 instead of the concave portion at the tip end of the tapered spring or the piston 3. Reduce the impact of the weight 5 when impacting Just fine.

The weight 5 is housed inside the piston spring 2, and is configured to move forward and backward in the weight housing portion 3A together with the piston spring 2. As described above, by accommodating the weight 5 in the piston spring 2, the stroke of the piston spring 2 can be made large inside the mechanism portion P where the space is limited. In the example of the drawing, the piston spring 2 inserted from the rear is provided in the weight accommodating portion 3A of the piston, and the cylindrical weight 5 is movably provided inside the piston spring 2 (see the second Figure).

Further, the weight spring 5A is coupled to the rear of the weight 5. The weight spring 5A is a coil spring that presses and pushes the weight 5 toward the weight accommodating portion 3A. Further, when the weight 5 is pressed by the weight spring 5A and the weight 5 is pushed, a backlasher like a real gun is generated. At this time, the locking flange 5B is formed by forming the shaft diameter of the rear portion of the weight 5 to be thinner than all the shaft diameters, and the front end of the weight spring 5A is locked to the locking flange 5B ( Refer to Figure 9).

The piston spring 2 is disposed so as to be surrounded by the spring guide portion 7 of the casing P1 of the mechanism portion P (see Fig. 1). Further, the spring guide portion 7 is configured to correct the bending deformation of the piston spring 2 generated when the piston spring 2 is compressed (see Fig. 3). The spring guide portion 7 of the drawing is formed in a rail-shaped projection formed inside the casing P1 for accommodating the organ portion P (see Fig. 8). Further, the bending deformation can be corrected by arranging the plurality of spring guide portions 7 on the outer side of the long side surface of the piston spring 2.

Next, the operation of the mechanism unit P including the kickback generating mechanism of the present invention will be described based on Figs. 2 to 7 . As shown in Fig. 2, when the trigger T is pulled and energized, the piston rack 3D is moved rearward by the rotation of the sector gear S. At this time, as the piston 3 moves rearward, the cushion body 6 and the piston spring 2 and the weight spring 5A inside the piston 3 are retracted.

As shown in Fig. 3, the weight 5 integrally formed with the piston 3 moves further rearward together with the piston spring 2 and the weight spring 5A. At this time, the compressed air is sucked into the inside of the cylinder 4 in front of the piston 3.

As shown in Fig. 4, the piston rack 3D is disengaged from the sector gear S at the time point when the piston 3 is moved to the rearmost end.

As shown in Fig. 5, the piston 3 is in a free state, so that the pressing of the piston spring 2 causes the piston 3 to rapidly accelerate in the forward direction. Meanwhile, although the weight spring 5A presses and pushes the weight 5, since the weight 5 is heavier than the piston 3, it moves slower than the piston 3. At this time, the cushion body 6 is also stretched to its original length due to its own elastic force.

As shown in Fig. 6, the lightweight piston 3 advances rapidly, and the weight 5 pressed by the weight spring 5A is delayed in the moment, and then rapidly advances in the weight storage portion 3A to catch up. piston. At this time, the pressure in the cylinder 4 rises and the projectile Q is started to be emitted, and at the same time, a kickback accompanying the rapid advancement of the weight 5 occurs, and the entire frame P1 is pushed back toward the rear. The timing of the above-mentioned launch and recoil is almost the same as that of the real gun. In the case of a toy gun, the accuracy of the hit accuracy due to the kickback does not occur because the mass of the gun body portion of the entire frame P1 is covered.

As shown in Fig. 7, the counterweight 5 is generated immediately after the front end of the piston 3 hits the front end of the cylinder 4, although the piston 3 is struck by the pressing force of the weight spring 5A, but by buffering The body 6 is retracted to cause the weight 5 to be decelerated, so that the shooter does not feel the discomfort. Reference numeral 4B in the drawings is for protecting the cushion rubber sheet of the cylinder 4 when the piston 3 collides.

In addition, the mechanism unit P or the piston-cylinder device 1 of the present invention is not limited to the example of the drawings, and can be changed to other shapes without departing from the scope of the invention.
