Description

  The present invention relates to a reaction generating mechanism of a toy gun that can generate a reaction shock like a real gun when a toy gun is fired.

  A mechanism for generating a reaction (recoil shock) similar to that of a real gun when a BB bullet is fired with a toy gun has been proposed. For example, the air gun described in Patent Document 1 is provided with a barrel that is linked to the tip of a piston that moves back and forth, and a weight and a recoil spring are attached to the barrel. At the time of launch, when the barrel advances with the advance of the piston, the weight loosely fitted on the barrel and the recoil spring move back and forth to generate a reaction.

  On the other hand, the reaction generating mechanism described in Patent Document 2 uses a transmission rod that interlocks with the reciprocating motion of a piston, instead of the barrel of Patent Document 1 with a transmission rod. A hollow portion is formed in the transmission rod, and a buffer rod and a buffer rod spring are slidably provided in the hollow portion. Such a transmission rod moves a weight and a recoil spring to generate a reaction.

Japanese Utility Model Publication No. 5-47991 Japanese Patent No. 4995938

  All of the conventional reaction generating mechanisms are configured to move the weight and recoil spring back and forth using a barrel, a transmission rod, or the like interlocked with the piston. Therefore, the positions where these weights and recoil springs are arranged must be arranged at positions away from the engine part, such as in front of and behind the engine part where the piston is installed. As a result, the size of a toy gun provided with a conventional reaction generating mechanism has been limited to a large toy gun.

  For example, when a reaction generating mechanism is arranged behind the engine unit, a gun shoulder pad is used. Further, when the reaction generating mechanism is arranged in front of the engine unit, it is arranged using a long barrel. As described above, the conventional reaction generating mechanism can be attached only to a large toy gun such as a rifle, and it is extremely difficult to attach to a small toy gun such as a rifle or a handgun without shoulder pads. there were.

  Moreover, the reaction that occurs when a bullet is fired with a real gun is generated from the engine part where the bullet is loaded. It is a structure which moves and generates a reaction. For this reason, the conventional reaction generating mechanism has a difficulty in that it feels different from the impact of a real gun reaction.

  Therefore, the present invention was created to solve the above-mentioned problems, and can be applied to a small toy gun with an extremely compact configuration, and the position where the reaction of the actual gun occurs can be realistically reproduced. The object is to provide a reaction generating mechanism for a toy gun.

  In order to achieve the above-mentioned object, the first means in the present invention is a reciprocation of the piston / cylinder device 1 disposed in the engine part P of the toy gun and generating compressed air by the piston spring 2 and the piston 3 of the piston / cylinder device 1. In the toy gun reaction generating mechanism, which has a weight 5 that moves back and forth with movement and generates a reaction by the movement of the weight 5 in conjunction with the piston 3 when the bullet Q is fired, a weight storage portion 3A is formed inside the piston 3 In addition, the coil spring-like piston spring 2 is housed in the weight housing portion 3A, and a weight 5 is disposed in the piston spring 2 so as to be movable back and forth, and a weight spring 5A is connected to the rear of the weight 5 When the bullet Q is fired, the piston spring 2 moves the piston 3 toward the tip of the cylinder 4 at a high speed. , Lies in the structure to generate reaction by weight spring 5A chasing the piston 3 is pressed and urged the weight 5 to the weight accommodating portion 3A.

  The toy gun that is the subject of the present invention relates to a toy gun that uses a piston cylinder device 1 to generate a recoil shock. Therefore, the mechanism for driving the piston cylinder device 1 is not limited to the electric type, and any mechanism such as a manual compressed air type or a piston type using a fluid such as gas can be selected.

  For the piston 3 of the present invention, it is desirable to select a relatively weighing material such as synthetic resin, aluminum, titanium, carbon fiber, and magnesium, and to select a heavy metal material for the weight 5. Further, the shape, material, weight and the like of the weight 5 can be arbitrarily set. Further, in the shape of the weight storage portion 3A for storing the weight 5, a weight storage portion having an arbitrary shape such as a concave shape in which the rear end of the piston 3 opens or a weight storage portion 3A having a space independent from the surroundings inside the piston 3 is provided. It is possible to form the part 3A.

  The second means is that a buffer body 6 is installed between the front end of the weight 5 disposed in the weight storage portion 3A of the piston 3 and the inner surface 3B of the front end portion of the piston 3. The impact force at the time of collision of the weight 5 is reduced. As the buffer body 6, a material that reduces the impact force at the time of collision of the weight 5 such as a rubber material, a synthetic resin material, a bellows-like air cushion body, and an oil cushion is selected in addition to a straight coil spring and a taper spring.

  The third means is that the piston spring 2 is disposed so as to be surrounded by a spring guide portion 7 provided in the engine portion P, and the swell of the piston spring 2 generated when the piston spring 2 is compressed is spring-guided. This is because the correction is made by the unit 7.

  As in claim 1 of the present invention, the weight storage portion 3A is formed inside the piston 3, the piston spring 2 is stored in the weight storage portion 3A, and the weight 5 can be moved back and forth inside the piston spring 2. The weight spring 5A is connected to the rear of the weight 5, and when the bullet Q is fired, the piston spring 2 moves the piston 3 to the tip side of the cylinder 4 at a high speed, and the weight spring 5A follows the piston 3 Since the reaction is generated by pressing and urging the weight 5 in the weight storage portion 3A, it can be mounted even in a small space in the engine portion. Therefore, it is possible to mount even a small gun that has been difficult to mount with the conventional reaction generating mechanism, and it has been possible to provide a reaction generating mechanism that can be applied to toy guns of all sizes ranging from rifles to pistols. .

  Moreover, immediately after the bullet Q is fired, the weight spring 5A presses and biases the weight 5 following the piston 3 that moves at a high speed in the engine part P, so that a reaction is generated. Can be reproduced realistically.

  As in claim 2, a shock absorber 6 is installed between the tip of the weight 5 disposed in the piston 3 and the inner surface 3 </ b> B of the tip of the piston 3, and the shock when the weight 5 collides with the shock absorber 6. By being configured to reduce the force, in particular, it can withstand severe use situations in which the motor is rapidly accelerated and retracted repeatedly, such as an electric air gun, and can effectively relieve intense shock at the time of collision. As a result, damage to various parts such as the piston cylinder device 1 is reduced, and an unpleasant collision feeling when the weight 5 collides is reduced, and a recoil shock-like sensation at the time of actual gun shooting is obtained.

  As in claim 3, the piston spring 2 is disposed so as to be surrounded by the spring guide portion 7 formed in the engine portion P, and the spring guide portion 7 corrects the undulation of the piston spring 2 when the piston spring 2 is compressed. By configuring as described above, it is possible to maintain an accurate expansion and contraction operation of the piston spring 2. Therefore, when the piston 5 is compressed again after the weight 5 moves forward and causes a reaction, the piston spring 2 can be compressed at a normal position, and the exact expansion and contraction of the piston spring 2 can be repeated. .

  According to the reaction generating mechanism of the present invention, it is applicable to a small toy gun such as a gun or a handgun having a very compact configuration without a shoulder pad, and it becomes possible to reproduce the position where the reaction of the actual gun occurs in real. Achieved the original purpose.

  Examples of the present invention will be described below. The reaction generating mechanism of the present invention is mounted on a toy gun in which the piston cylinder device 1 is disposed in the engine portion P and the piston spring 2 generates compressed air. In the illustrated example, an electric engine part P is shown, and the main body of the toy gun is omitted. However, the engine part P is installed as a toy gun drive mechanism imitating a rifle, for example. Further, the drive mechanism of the engine part P is not limited to the illustrated electric type, and any mechanism such as a manual compressed air type or a piston type using a fluid such as gas can be selected.

  That is, the engine portion P of the present invention forms a weight storage portion 3A inside the piston 3, and stores the piston spring 2 formed of a coil spring in the weight storage portion 3A. The piston cylinder device 1 generates compressed air by the pressing force of the piston spring 2. Further, a weight 5 is arranged in the piston spring 2 so as to be movable back and forth (see FIG. 1). A weight spring 5 </ b> A is connected to the rear of the weight 5. When the bullet Q is fired, the piston spring 2 moves the piston 3 to the tip side of the cylinder 4 at a high speed, and the weight spring 5A pushes the weight 5 toward the inside of the weight storage portion 3A following the piston 3. This is a mechanism for generating a reaction.

  In the reaction generating mechanism of the present invention, the weight spring 5A presses and biases the relatively heavy weight 5 after the piston spring 2 moves the piston 3 which is relatively lightweight toward the tip of the cylinder 4 at high speed. Then, immediately after the piston 3 fires the bullet Q, a reaction occurs when the weight 5 moves in the weight storage portion 3A, so that a reaction close to an actual gun is generated from the engine portion P (see FIG. (See 5, 6).

  The weight storage portion 3A in the illustrated example has a concave shape in which the rear end portion is opened in the member constituting the piston 3, and is inserted with the front end of the weight 5 facing in the direction of the front end portion inner side surface 3B that is the front end side of the recess. (See FIG. 2). The material of the piston 3 is selected from relatively weighing materials such as synthetic resin, aluminum, titanium, carbon fiber, and magnesium, so that the piston 3 can be moved at a high speed and at the time of collision between the tip of the piston 3 and the cylinder 4 Damage can be reduced. On the other hand, by selecting a heavy metal material as the material of the weight 5, a larger reaction can be obtained. The shape, material, weight and the like of the weight 5 can be arbitrarily set.

  Further, when the weight 5 collides with the inner side surface 3B of the front end portion of the piston 3, the piston 3 and the cylinder 4 may be damaged (see FIG. 7). Therefore, a buffer body 6 is provided on the front end side of the weight 5, and the buffer body 6 is configured to reduce an impact force when the weight 5 collides. The buffer body 6 in the illustrated example uses a coil spring that protrudes from a recess at the tip of the piston 3 (see FIG. 1). In addition to this, the shock absorber 6 is a taper spring, a straight spring housed in the groove instead of the concave portion at the tip of the piston 3, a rubber material, a synthetic resin material, a bellows-like air cushion body, an oil cushion, or the like. Anything that reduces the impact force at the time of collision is sufficient.

  The weight 5 is housed inside the piston spring 2, and is configured to move back and forth in the weight housing portion 3A together with the piston spring 2. By storing the weight 5 in the piston spring 2 in this way, the stroke of the piston spring 2 can be increased inside the engine part P where the space is limited. In the illustrated example, a piston spring 2 to be inserted from the rear is provided in the piston weight storage portion 3A, and a columnar weight 5 is disposed in the piston spring 2 so as to be movable back and forth (see FIG. 2).

  Further, a weight spring 5 </ b> A is connected to the rear of the weight 5. The weight spring 5A is a coil spring that presses and biases the weight 5 toward the weight storage portion 3A. When the weight 5 is pressed and urged by the weight spring 5A, a reaction like an actual gun occurs. At this time, the shaft 5 at the rear portion of the weight 5 is formed to be thinner than the entire shaft diameter to form the locking flange 5B, and the tip of the weight spring 5A is locked to the locking flange 5B (see FIG. 9).

  The piston spring 2 is disposed so as to be surrounded by a spring guide portion 7 provided in the housing P1 of the engine portion P (see FIG. 1). Then, the swell of the piston spring 2 generated when the piston spring 2 is compressed is corrected by the spring guide portion 7 (see FIG. 3). The illustrated spring guide portion 7 is a rail-like protrusion formed inside the housing P1 that houses the engine portion P (see FIG. 8). Then, the plurality of spring guide portions 7 are arranged on the outer side along the longitudinal side surface of the piston spring 2 to correct the swell.

  Next, the operation of the engine part P provided with the reaction generating mechanism of the present invention will be described with reference to FIGS. As shown in FIG. 2, when the trigger T is pulled and energized, the piston rack gear 3 </ b> D moves backward by the rotation of the sector gear S. At that time, as the piston 3 moves backward, the buffer body 6 and the piston spring 2 inside the piston 3 and the weight spring 5A are degenerated.

  As shown in FIG. 3, the weight 5 integrated with the piston 3 moves further rearward together with the piston spring 2 and the weight spring 5A. At this time, compression air is taken into the cylinder 4 in front of the piston 3.

  As shown in FIG. 4, when the piston 3 moves to the end, the sector gear S is detached from the piston rack gear 3D.

  As shown in FIG. 5, the piston 3 is in a free state, and the pressing bias of the piston spring 2 rapidly accelerates the piston 3 toward the forward direction. At the same time, the weight spring 5 </ b> A presses and biases the weight 5, but the weight 5 is heavier than the piston 3, and therefore moves after the piston 3. At this time, the buffer body 6 also extends to the length of the base by its own elastic force.

  As shown in FIG. 6, the lightweight piston 3 moves forward rapidly, and the weight 5 pushed by the weight spring 5 </ b> A rapidly advances in the weight storage portion 3 </ b> A so as to follow the piston after an instant time lag. At this time, the pressure in the cylinder 4 is increased, the launch of the bullet Q is started, and at the same time, a reaction due to the rapid advance of the weight 5 occurs, causing a phenomenon in which the entire housing P1 is pushed back. The timing of this firing / reaction is almost the same as that of an actual gun, and even in the case of a toy gun, the accuracy of the hit accuracy associated with the reaction does not occur due to the mass of the gun body covering the entire housing P1.

  As shown in FIG. 7, the weight 5 that has reacted immediately after the tip of the piston 3 hits the tip of the cylinder 4 collides with the piston 3 due to the pressing force of the weight spring 5A. At this time, the buffer body 6 contracts. By rapidly decelerating the weight 5, a sense of collision unpleasant to the shooter is not felt. Reference numeral 4B in the figure denotes a shock absorbing rubber plate that protects the cylinder 4 when the piston 3 collides.

  In addition, the engine part P and the piston cylinder device 1 of the present invention are not limited to the illustrated examples, and can be changed to other shapes as long as the gist of the present invention is not changed.
