  • Patent number: 5695194
    Abstract: A domed game including a transparent dome mounted to a hollow base with game balls enclosed therein. The base has a top surface comprising a shoulder and a concave cavity. A plurality of ball recesses are arranged along the shoulder. A colored lever is associated with each of the ball recesses. Protruding from the top of the dome is a movable activating member. When the activating member is moved to an activated state an engaging member connected to the activating member, slides to an engaged position whereby power is supplied to a motor. The motor is operatively connected to a rotating member in the bottom of the base which rotates and thereby causes the balls in the base to randomly project into the dome. Some of the projected balls will randomly fall or drop into the ball recesses. The user depresses the lever and thereby ejects from the ball recess balls that do not match in color with the associated lever.

  • Patent number: 5279276
    Abstract: A slingshot is operable for propelling a projectile toward a target. The projectile is formed as a body from which a pair of elastic members outwardly and nondetachably extend. The slingshot includes a yoke having first and second substantially upwardly and outwardly extending prongs and a user-graspable handgrip depending downwardly. Each of the prongs carries one of a pair of confrontingly opposed posts that extend outwardly from the prong and on the periphery of which a slot is defined. In use, the elastic members are releasably received in the respective post slots and the projectile is grasped by the user and drawn rearwardly to stretch the elastic members against their elastic urgency. When the projectile is then released, the elastic members contract that propel the projectile toward the target. As the projectile passes between and beyond the yoke prongs, the elastic members are released from the post slots and travel with the projectile body toward the target.

  • Patent number: 4786269
    Abstract: A four-wheel drive toy vehicle having a spring-wound motor capable of travelling over hills and other obstacles. The vehicle is provided with front and rear traction wheel sets whose axles extend across the chassis which support the body. Each axle has a pinion thereon which engages the front section of a two-section coupling gear that meshes with the input gear of a flat spiral spring motor whose output gear engages the rear section of the coupling gear. The input gear is coupled to the input of the spring through a one-way clutch whereby when the vehicle is grasped by the player and pulled back along the ground, the input gear is caused to turn by both pinions to thereby wind up the spring; and when the vehicle is released, the output gear which is turned by the unwinding spring then acts to drive both pinions to advance the vehicle in the foward direction. One of the pinions is coupled by a gear train to a governor which acts to regulate the speed of wheel rotation.
