  • Patent number: 7160171
    Abstract: In accordance with the present invention there is provided a pneumatic pump in combination with a pneumatic toy vehicle powered by a refillable compressed chamber. The improvement of the pump is defined by having a pipe that has an aperture to exhaust air being pumped therefrom. The pump further includes a means for launching the vehicle from the pump. The toy vehicle includes a pneumatic motor that when activated utilizes air in the chamber to propel the vehicle and activation of the motor is achieved by moving the vehicle. The vehicle includes an air inlet valve sized to securely engage the pipe of the pump such that movement of the vehicle during filling of the chamber is prevented. When securely engaged by the pipe, the vehicle is positioned against the launching means. A user operating the launching means pushes the vehicle, which activates the motor, such that the vehicle launches away from the pump.

  • Patent number: 7036307
    Abstract: In one embodiment, a pneumatic power-supply assembly includes a refillable chamber having an interior capable for holding a pressurized fluid, a vent, and a fluid inlet. A pressure release mechanism within the chamber permits the pressure within the chamber to vent, when the pressure exceeds a predetermined optimum pressure. A pneumatic motor is mounted within the chamber and includes an inlet in fluid communication with the interior of the chamber. The pneumatic motor utilizes the pressurized fluid within the interior of the chamber to drive a gear rotatably attached to the pneumatic motor. In addition, the gear rotates an axle rotatably attached to the chamber such that the when the assembly is attached to a pneumatic operated device the rotatable axle may be used by the pneumatically operated device. In addition, a external pump is attached to the fluid inlet to continually recharge the chamber.

  • Patent number: 6862973
    Abstract: In one embodiment a pneumatic motor is provided that includes an intake chamber in fluid communication with at least one intake channel. Each intake channel is further in fluid communication with a corresponding cylinder, which receives a piston that cycles upwardly and downwardly to rotate a motor axle. A member is placed in each intake channel to seal the corresponding cylinder from each intake channel when compressed fluid in the intake channel has a higher pressure then pressure in the corresponding cylinder. Each piston includes an actuator extending downwardly from the piston and having a profile that, during a portion of the upward cycle of the piston, causes the actuator to push the member back into each intake channel to allow compressed fluid into each of the corresponding cylinders. Each piston includes an intermediate section that has an annular groove, a seal positioned in the groove that creates a fluid tight seal against the corresponding cylinder during the upward cycle of the piston.

  • Patent number: 6622333
    Abstract: In accordance with one embodiment of the present invention a pneumatic-operated toothbrush incorporates a pump that a user may utilize to pump are into and pressurize air in a reservoir. The reservoir is attached to a pneumatic motor, which utilizes the pressurized air inside the reservoir to rotate a drive shaft. Attached to the end of the drive shaft is a plurality of bristles that rotate when the drive shaft is rotating. The motor will continue to rotate the bristles as long as the pressure inside the reservoir is sufficient enough to force the air into the pneumatic motor. When the motor stops rotating the bristles, the user can pump air back inside the reservoir for continued use. It is important to note that the pneumatic toothbrush for the present invention is a self-contained device, meaning that the reservoir, motor and pump are incorporated into a single toothbrush. In addition the present invention does not use batteries or other electrical elements to power the motor.

  • Patent number: 6401970
    Abstract: A candy dispenser may be provided with a housing having a candy reservoir formed therein in which a plurality of pieces of candy may be disposed, a spin top having a downwardly extending member that is centrally located on the spin top to facilitate spinning of the spin top while the downwardly extending member supports the spin top, a candy dispensing mechanism including a candy dispensing opening that allows a piece of candy to be dispensed from the candy reservoir, and an actuator associated with the spin top and the candy dispensing mechanism. The actuator may be movable to a first position and to a second position, with movement of the actuator to the first position causing the spin top to be launched from the housing so that the spin top may land on a surface and spin on its downwardly extending member, and with movement of the actuator to the second position causing one of the pieces of candy to be dispensed through the dispensing opening.
