Abstract

A toy gun includes 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. The sliding rod is disposed in the housing and spaced apart from the weight. The backward momentum transferring mechanism can simulate recoil by generating a recoil shock.

Claims

1. A toy gun comprising:

a housing;

a bullet loading unit in a forward end of the housing;

a piston in a fixed cylinder of the housing;

a gunstock coupled to the housing; and

a backward momentum transferring mechanism partially disposed in the gunstock and including an intermediate weight, a 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 a stop wall formed in the gunstock;

wherein the sliding rod is disposed between the piston and the intermediate weight and spaced apart from the weight, a front end of the sliding rod engages with the piston, and a rear end of the sliding rod extends into the gunstock.

2. The toy gun as claimed in claim 1, wherein the sliding rod is a spring biased rod.

3. The toy gun as claimed in claim 2, wherein the spring biased rod comprises a receptacle, a helical spring disposed in the receptacle, and an elongated rod partially disposed in the receptacle and having an end engaged with the helical spring, such that the elongated rod is adapted to slide relative to the receptacle.

4. The toy gun as claimed in claim 3, wherein the receptacle is formed with a hollow space and the helical spring is disposed in the hollow space of the receptacle.
