  • Patent number: 11940241
    Abstract: A toy launcher with a drum magazine assembly that has a rotatable drum portion mounted for rotation, with a rear plate and a central support with an opening for a support axle. A ring of projectile holders is connected to the rear plate, with each projectile holder holding at least two projectiles arranged in a generally radially stacked configuration. Generally radially extending walls are located between adjacent projectile holders. Each of the projectile holders includes a slot on a radially inner side into which a projectile biasing arm extends at a projectile launch position. A pusher is located in the housing adjacent to the projectile launch position. Drive wheels are positioned in front of the drum magazine assembly at the projectile launch position. The drive wheels are motorized so that they rotate to propel a projectile pushed from the drum between the drive wheels for launching the projectile.

  • Patent number: 7131557
    Abstract: A toy water gun having a water supply tank which can be filled with water, and a water pump located on the housing for pumping water from the supply tank to at least one water pressure chamber. The water pressure chamber includes a fixed wall, and a moveable wall which substantially sealingly engages the fixed wall and is slidable away from a first end wall as water is pumped into the water pressure chamber and toward it as water is discharged. An air pressure chamber is located on an opposite side of the moveable wall from the water pressure chamber and is pressurizable with compressed air to bias the moveable wall toward the first end wall. A pump is connected to a selector valve assembly which, in a first state, allows air to be pumped into the air pressure chamber for pressurizing it with compressed air and, in a second state, places the pump in communication between the water supply tank and the water pressure chamber to allow water to be pumped from the supply tank to the water pressure chamber.
