Abstract
A thrown toy has a water tank with valves which are opened by centrifugal force. When thrown, the toy is designed to whirl so that the centrifugal force opens a valve and water is dispersed out the valves while the toy is in flight.
Claims13
A thrown water toy comprising a water tank having at least one valve therein, the valve having spring means for normally urging said valve to a closed position, the valve having associated means responsive to centrifugal forces for acting against said spring means and opening said valve.
A water disk comprising an upper and a lower compartment sealed in face to face contact in order to form a water tank, a plurality of valve areas formed in said water tank, each of said valve areas having a shaft mounted therein to open or close a valve responsive to a centrifugal force, a spring support plate, a ball valve shutter, and spring means associated with said spring support plate for pulling said ball valve shutter against a valve seat in said valve area, said spring means exerting an amount of spring bias which is overcome by centrifugal force when the disk is thrown with a whirling motion.
A toy comprising an upper toroidal hard plastic member having a fill opening therein, a lower hard plastic toroidal member, said upper and lower toroidal members being sealed together in a face to face contact in order to form a water tank, said tank having a periphery, four box-like radial projections on said water tank, said projections being separated from each other by approximately a 90.degree. displacement around the periphery of the tank, each of said projections having a hole surrounded by a valve seat, valve means closing said valve seat, said valve means comprising a shaft slidably mounted in said hole and having a spring seat on one end and means for closing and opening said valve seat on the other end, and a spring on said shaft and positioned between said spring set and said valve seat for urging said means for closing and opening said valve seat to a closed position, the bias of said spring being such that centrifugal force urges said means for closing and opening said valve seat to an open position.
A thrown water toy comprising:
- a water tank having at least two opposed valves therein;
- means for normally urging said valves to a closed position;
- and
- mass means associated with said urging means for experiencing centrifugal force when said water tank is thrown with a whirling motion;
- said mass means opening said valves in response to said centrifugal forces, whereby said valves are opened only when said water tank is thrown with a whirling motion.
A thrown water toy comprising:
- a water tank having at least one valve therein;
- said valves being substantially symmetrically arranged about a preferred axis of rotation;
- means for normally urging said valve to a closed position;
- and means associated with said valve for opening said valve in response to rotation of said water tank about said axis of rotation when said toy is thrown with a whirling motion.
