Abstract

A toy launch apparatus which includes single motor synchronized quick start/advanced start flywheel apparatus employing a drive mechanism for advancing rotation of projectile-propelling flywheels and driving a projectile-feeding advance mechanism for automatic and sequenced projectile-launching operation, with movement of the pusher mechanism to rapidly fire darts from the toy apparatus. The system apparatus and methods employing the single-motor-driven mechanism facilitate advanced starting projectile-propelling flywheels and driving a projectile-feeding mechanism in a novel fashion for automatic and sequenced projectile-launching operation with reduced mechanism mass and cost.

First claim

What is claimed is:

1. A toy projectile launch apparatus, comprising:
a motor;
projectile propelling flywheels linked to the motor;
a clutch structure engaging the flywheels through a flywheel gear train, the clutch structure including a swing gear operable between first and second positions;
a pusher mechanism disposed adjacent the flywheels and engaging the motor for advancing projectiles into the flywheels one at a time; and
a trigger assembly including a trigger and trigger linkage assembly linked to the swing gear and engaging the clutch structure and the pusher mechanism, the trigger assembly jump starting rotation of the flywheels to an operating speed and activating the clutch structure when the flywheels are rotating at the operating speed, shifting the swing gear into the second position for actuating the pusher mechanism causing back and forth motion of the pusher mechanism advancing projectiles into the rotating flywheels when the trigger is pulled.

2. The toy projectile launch apparatus according to claim 1 ,
wherein the clutch structure includes a centrifugal-clutch initiating the pusher mechanism upon the flywheels having a desired rotational speed for propelling projectiles.

3. The toy projectile launch apparatus according to claim 2 ,
wherein the swing gear links a pusher/feeding gear train to the centrifugal-clutch which includes a clutch attached gear for transmitting power to the pusher/feeding gear train through the swing gear.

4. The toy projectile launch apparatus according to claim 3 ,
further comprising a cam and follower interaction between a crank gear and a pusher mechanism linkage when the swing gear mechanically engages the crank gear powered by the motor, operating to sequence and activate the pusher mechanism and flywheel propelling mechanism.

5. The toy projectile launch apparatus according to claim 4 ,
further comprising a micro-switch engaging the trigger and the motor for activating the motor when the trigger is depressed and shutting off power to the motor when the trigger is released.

6. The toy projectile launch apparatus according to claim 5 ,
wherein the trigger linkage assembly mechanically engages the swing gear and shifts the swing gear from a first position to the second position when the trigger is pulled.

7. The toy projectile launch apparatus according to claim 6 ,
wherein the swing gear is spring biased to the first position.

8. The toy projectile launch apparatus according to claim 7 ,
wherein the pusher/feeding gear train employs a scotch gear and swing gear linkage coupling the scotch gear to the swing gear allowing the swing gear to shift between first and second positions.

9. The toy projectile launch apparatus according to claim 1 ,
wherein the clutch structure further comprises a torsion booster spring engaging the motor through a spring winding gear train and engaging the flywheels through the flywheel gear train, the torsion booster spring is primed to a charged position when the motor is turned on and the trigger assembly jump starting the flywheels through the torsion booster spring.

10. The toy projectile launch apparatus according to claim 8 ,
further comprising a two-motor power system, with a first motor coupled to a first flywheel and a second motor coupled to a second flywheel, with first and second motors driving rotation of first and second flywheels, respectively, and the pusher/feeding mechanism.

11. A toy projectile launch apparatus, comprising:
a magazine for receiving and holding projectiles;
a carriage structure including a launch channel being supporting with the magazine;
a feeding mechanism in communication with the magazine for injecting projectiles from the magazine into the launch channel;
a propelling mechanism coupled with the carriage structure and including flywheels in communication with the launch channel for propelling projectiles from the magazine;
a feeding and launching motor;
a transmission gear assembly powered with the motor to sequence and activate the feeding mechanism and the propelling mechanism; and
a clutch in communication transmission gear assembly to activate the feeding mechanism with the motor.

12. The toy projectile launch apparatus according to claim 11 , wherein the clutch in communication transmission gear assembly powered with the motor operates to sequence and activate the feeding mechanism and the propelling mechanism.

13. The toy projectile launch apparatus according to claim 12 , wherein the feeding mechanism comprises a spring biased cam follower from the transmission gear assembly, the spring biased cam follower which extends and retracts between a first extended and a second retracted position to engage and shuttle additional projectiles from the magazine, returning to the second retracted position to engage another projectile from the magazine.

14. The toy projectile launch apparatus according to claim 11 , wherein the clutch comprises a manually operable activation trigger button.

15. A method for launching projectiles, comprising the steps of:
providing a motor;
providing projectile propelling flywheels linked to the motor;
providing a clutch structure engaging the flywheels, the clutch structure including a swing gear operable between a first position a second position;
providing a pusher mechanism disposed adjacent the flywheels and engaging the motor;
providing one or more projectiles at the pusher mechanism;
providing a trigger assembly including a trigger and trigger linkage assembly linked to the swing gear and engaging clutch structure and the pusher mechanism;
pulling the trigger turning the motor on jump starting rotation of the flywheels and pulling the swing gear to the second position and into engagement with the pusher mechanism;
obtaining operating speed at the flywheels and engaging the clutch structure to rotate; and
transmitting power from the motor to the pusher mechanism causing back and forth motion of the pusher mechanism advancing projectiles one at a time into the rotating flywheels when the trigger is pulled.

16. The method for launching projectiles according to claim 15 , further comprising the step of providing a centrifugal clutch as the clutch structure to initiate the pusher mechanism upon the flywheels obtaining a desired rotational speed for propelling projectiles.

17. The method for launching projectiles according to claim 16 , further comprising the step of providing a micro switch engaging the trigger and the motor activating the motor when the trigger is pulled and shutting off power to the motor when the trigger is released.

18. The method for launching projectiles according to claim 17 , further comprising the step of providing a trigger linkage assembly mechanically engaging the swing gear to shift from a first position to a second position.

19. The method for launching projectiles according to claim 18 , further comprising the step of spring biasing the swing gear to the first position.

20. The method for launching projectiles according to claim 19 , further comprising the step of providing a scotch gear coupled to the swing gear through a swing gear linkage securing the swing gear to shift between first and second positions.
