  • Patent number: 8297269
    Abstract: A gun bolt transmission mechanism used in an electric toy gun is disclosed to include a driving member pivotally mounted in the gun body of the electric toy gun at one side of a bolt body that accommodates a piston set, and a push rod located on a gear set for moving the driving member to push the bolt body backwards during rotation of the gear set and for enabling the bolt body to be returned after rotation of the gear set through a predetermined angle to disengage the push rod from the driving member. Thus, the bolt body simulates the motion of a real gun and the movement of the piston set does not interfere with the movement of the bolt body.

  • Patent number: 8156930
    Abstract: A cartridge box of a pneumatic toy gun includes an air lock system and a struck element disposed on the upper inside the case of the cartridge box, and further includes a control system having a pushing rod and a resisting rod, wherein a front end of the pushing rod extends into the bullet-out passage disposed inside the case. When there is no bullet in the bullet-out passage, a lateral end of the stripping rod resists upward against the front end of the pushing rod to make the back end of the resisting rod moving downward to resist against the resisting portion of the struck element, resulting that the struck element cannot push the air lock system forward. Thereby, when there is no bullet in the cartridge box, even if the trigger is pressed, the air lock system cannot moves to push the bolt. Hence, firing without bullet will be avoided and the effects of the simulate gun would be achieved.

  • Patent number: 8146577
    Abstract: An electric toy gun having therein a power break control mechanism consisting of an actuator, a power break control set and a swinging block for breaking off power supply upon triggering of the trigger when the clip is empty. When the clip is empty and when the trigger is pressed, the actuator is forced by a spring-loaded push rod at the bullet outlet of the clip to move the swinging block and the power break control set, causing a power break holder to be moved away from a power contact holder, and therefore power supply is disconnected, avoiding waste of power supply and component damage.

  • Patent number: 8146576
    Abstract: A firing actuator mechanism used in a toy gun is disclosed to include a trigger mechanism, a link having a push portion and a stop portion at the rear side thereof, a retaining mechanism formed of a holder block and a sliding block, a hammer and a locking block. The sliding block has an engagement portion at the front side, and a first side rod and a second side rod at one lateral side. When the link is moved backwards during a single fire mode, the push portion forces the first side rod to move the sliding block backwards. When the link is moved backwards and the rear end portion is forced downwards during a continuous fire mode, the stop portion is stopped against the second side rod of the sliding block. The hammer has a durable press portion lockable by the locking mechanism.

  • Patent number: 8051847
    Abstract: A toy gun gas intake control mechanism includes a holder frame, an impact member having an elongated pivoted with its bottom end to the holder frame, a striking block, a pivot axle that pivotally connects the striking block to the top end of the elongated base and a spring member for revering the striking block, a retaining block supported on a spring member in the holder frame and having a retaining notch for retaining the outer end of the pivot axle. When firing a bullet, the bolt body of the toy gun moves forwards, the striking block strikes a seal member to open a gas inlet, and the pivot axle is moved out of the retaining notch of the retaining block for allowing upward displacement of the retaining block. When the bolt body moves backward after firing, the retaining block is forced downwards to the inside or the holder frame by the bolt body, the outer end of the pivot axle is engaged into the retaining notch, and the striking block is returned, causing the seal member to close the gas inlet again.

    Abstract: A firing actuator mechanism used in a toy gun is disclosed to include a trigger mechanism, a link having a push portion and a stop portion at the rear side thereof, a retaining mechanism formed of a holder block and a sliding block, a hammer and a locking block. The sliding block has an engagement portion at the front side, and a first side rod and a second side rod at one lateral side. When the link is moved backwards during a single fire mode, the push portion forces the first side rod to move the sliding block backwards. When the link is moved backwards and the rear end portion is forced downwards during a continuous fire mode, the stop portion is stopped against the second side rod of the sliding block. The hammer has a durable press portion lockable by the locking mechanism.
