Definitions

  • the invention relates to toy guns and more particularly to a backward momentum transferring mechanism for a toy gun for simulating recoil by generating a recoil shock.
  • a typical toy gun comprises a trigger, a bullet loading device with bullets (e.g., plastic pellets) in a ready to shoot position, and a firing mechanism.
  • bullets e.g., plastic pellets
  • a shooter may press back the trigger to activate the firing mechanism to eject the bullet out of a barrel.
  • the conventional backward momentum transferring mechanism mainly includes a housing, a speed reduction gear, a trigger, a forward bullet loading unit, a piston, and a piston spring.
  • the speed reduction gear is operatively connected to a motor in a pistol grip.
  • the piston is moveably disposed in a fixed cylinder, and piston is biased the piston spring.
  • the trigger is exposed and can be used to activate the motor for firing when it is pressed backed by the finger.
  • a barrel extends forwardly of the housing.
  • a connection rod is firmly connected between the piston and a weight which is arranged in a gunstock of the housing.
  • the conventional structure of the backward momentum transferring mechanism exists a number of disadvantages.
  • the connection rod between the piston and the weight is firmly connected, the speed reduction gear and the piston are often damaged when the weight and the piston are not in cooperation in reciprocal motion.
  • the conventional backward momentum transferring mechanism can not generate clear metal sound.
  • the conventional backward momentum transferring mechanism is provided with a stop plate in the housing in order to stop the weight each time the weight is in a forward movement. As result, the components of the top gun are often damaged. In addition, the stop plate limits the travel stroke of the weight.
  • a toy gun comprising a housing; a barrel extending forwardly of the housing; a motor in a pistol grip; a speed reduction gear in the housing and operatively connected to the motor; a bullet loading unit in a forward end of the housing; a spring biased piston in a fixed cylinder of the housing; a trigger for activating the motor for firing; and a backward momentum transferring mechanism partially disposed in a gunstock and including an intermediate weight, a forward sliding rod disposed rearward of the piston, and a rear recoil spring having a front end urging against a rear end of the weight and a rear end urging against an internal wall in the gunstock, wherein the sliding rod is disposed in the housing and spaced apart from the weight.
  • FIG. 1 is a longitudinal sectional view of a main portion of a rifle-type toy gun according to the invention with a piston spring in an expanded state and incorporating a first preferred embodiment of backward momentum transferring mechanism;
  • FIG. 2 is a view similar to FIG. 1 with the piston spring compressed and the piston moved back as a result of the firing;
  • FIG. 3 is a view similar to FIG. 1 with a bullet leaving the barrel after firing;
  • FIG. 4 is a longitudinal sectional view of the spring biased rod
  • FIG. 5 is a longitudinal sectional view of the backward momentum transferring mechanism in accordance with a second embodiment of the present invention.

  • FIGS. 1 to 4 a rifle-type toy gun 100 according to the present invention incorporating a first preferred embodiment of backward momentum transferring mechanism 6 is shown.
  • the toy gun 100 in accordance with a first embodiment of the present invention comprises a housing 1, a speed reduction gear 2, a trigger 3, a forward bullet loading unit 4, a piston 5, and a piston spring 51.
  • the speed reduction gear 2, the trigger 3, the forward bullet loading unit 4, the piston 5, and the piston spring 51 are accommodated in the housing 1.
  • the speed reduction gear 2 is operatively connected to a motor in an inclined pistol grip.
  • the piston 5 is moveably disposed in a fixed cylinder 52, and piston 5 is biased the piston spring 51.
  • the trigger 3 is exposed and can be used to activate the motor for firing when it is pressed backed by the finger.
  • a barrel extends forwardly of the housing 1.
  • the backward momentum transferring mechanism 6 is partially disposed in a gunstock 12 and disposed rearward of the piston 5 (i.e., the housing 1).
  • the backward momentum transferring mechanism 6 and the piston 5 can co-act in a reciprocal fashion along a moving direction I of the piston 5.
  • the backward momentum transferring mechanism 6 comprises an intermediate weight 61, a spring biased rod 62 disposed rearward of the piston 5, and a rear recoil spring 63 having a front end urging against a rear end of the weight 61 and a rear end urging against a stop wall 11 in the gunstock 12.
  • a rear end of the spring biased rod 62 extends into a space formed in the gunstock 12 via a through hole formed on an internal wall 13 of the housing 1.
  • the spring biased rod 62 acts a sliding rod in this embodiment.
  • the backward momentum transferring mechanism 6 is disposed between the piston 5 and the intermediate weight 61.
  • a front end of the spring biased rod 62 engages with the piston 5, and a rear end of the spring biased rod 62 extends into the gunstock 12.
  • the spring biased rod 62 is spaced apart from the weight 61 and is slidably disposed in the housing 1.
  • the spring biased rod 62 comprises a receptacle 623, a helical spring 622 disposed in a hollow space 624 formed in the receptacle 623, and an elongated rod 621 partially disposed in the hollow space 624 of the receptacle 623 and having a front end engaged with a rear end of the spring 622.
  • the rod 621 can slide relative to the receptacle 623 as a result of the compression or expansion of the spring 622.
  • a shooter may press back the trigger 3 to activate the motor to eject a bullet (e.g., plastic pellet) out of the barrel. And in turn, the piston 5 is pushed back to move the rod 621 of the backward momentum transferring mechanism 6 rearward. The rod 621 further contacts the weight 61 and pushes same rearward. Thus, the recoil spring 63 is compressed by the weight 61. This action can simulate recoil.
  • a bullet e.g., plastic pellet
  • the backward momentum transferring mechanism 6a comprises a first weight 632, a second weight 633, a balance spring 634 interconnecting the first weight 632 and the second weight 633, a detent 636 on the underside of the second weight 633, an elongated rod 631 through the first weight 632, and a torsion spring 635 put on the rod 631 and biasing against the first weight 632.
  • the backward momentum transferring mechanism 6b comprises a receptacle 642, a torsion spring 643 in the receptacle 642, an elongated rod 641 having an enlarged end biased by the spring 643 so that the rod 641 can slide relative to the receptacle 642 back and forth without being detached therefrom, and a helical spring 644 urging against the end of the receptacle 642 distal the rod 641.
  • the backward momentum transferring mechanism 6c comprises a first weight 651, a rod 652 inserted into the first weight 651, a linking rod 655 connected to the first weight 651, a second weight 653 having a recess at one end facing the rod 652, and a helical spring 654 biased against the other end of the second weight 653.
  • the backward momentum transferring mechanism 6d comprises a first weight 661, a second weight 662, a rod 663 inserted into the second weight 662 and facing a recess at one end of the first weight 661, a linking rod 665 connected to the first weight 661, and a helical spring 664 biased against the second weight 662 distal the first weight 661.
  • the backward momentum transferring mechanism 6e comprises a first weight 671, a second weight 673 spaced from the first weight 671, a seat 675 spaced from the second weight 673 and further spaced from the first weight 671, a rod 672 having one end anchored in the first weight 671, the other end anchored in the seat 675, and the main portion passing the second weight 673, a helical spring 674 biased between the second weight 673 and the seat 675, and a linking rod 676 connected to the first weight 671.
  • the spring of the spring biased rod can absorb momentum transmitted from the weight if the piston and the weight are not in cooperation in reciprocal motion. This can prevent the piston from being damaged by the rod of the spring biased rod.
  • the spring biased rod and the weight are spaced apart. Thus, it can effectively transfer backward momentum to the gunstock.
  • a clear metal sound is generated when the spring biased rod collides with the weight in a backward movement (i.e., retreat). Also, a clear metal sound is generated when the spring biased rod collides with the housing in a forward movement (i.e., advancement).
  • baffle plates are provided in the gunstock.
  • the invention is more durable, the number of components is decreased, and the construction is simpler. Moreover, an increased moving distance is achieved by the weight so as to generate a recoil shock.
  • the spring biased rod is not a unitary member and is mounted with a spring. Thus, an improved buffering effect is made possible.
  • the spring biased rod of the invention can prevent the speed reduction gear and the piston from being damaged when the weight moves backward in response to the discharge of the toy gun.
