Toy guns
A toy gun has a body, a chamber and a nozzle. A piston moves within the chamber to cause fluid in the chamber to be emitted via the nozzle. A handle is connected to the body, and a gear mechanism cooperates with the handle and the piston to convert movement of the handle to lesser or greater movement of the piston.
1. A toy gun, comprising:
a body;
a chamber;
a nozzle;
a piston movable within the chamber to cause fluid in the chamber to be emitted via the nozzle;
a movable handle connected to the body;
a gear mechanism cooperating with the handle and the piston to convert movement of the handle to lesser or greater movement of the piston; and
a nozzle cover adapted to open the nozzle upon movement of the handle.
2. The toy gun of claim 1 , wherein the gear mechanism comprises a first rack attached to or formed integrally with the handle to move therewith, a second rack fixed to or formed integrally with the body, and one or more gears attached to the piston and cooperating with both racks.
3. The toy gun of claim 1 , further comprising a reservoir from which stored water is delivered to the chamber via a conduit and a one-way valve.
4. The toy gun of claim 1 , further comprising a carriage attached to the body and movable by the handle and wherein the nozzle cover is attached pivotally to the body and a linkage extends from the nozzle cover to the carriage.
5. The toy gun of claim 1 , wherein the handle is a priming handle and a spring bears against the piston, and wherein movement of the priming handle loads the spring.
6. The toy gun of claim 3 , wherein the handle is a firing handle causing movement of the piston in either direction, and wherein the chamber has a second one-way valve via which water passes to the nozzle.
7. The toy gun of claim 2 , wherein said one or more gears comprises one gear only, and wherein the teeth of the gear mesh with the teeth of both racks.
8. The toy gun of claim 2 , wherein said one or more gears comprises two gears of different size fixed on a common shaft, and wherein the teeth of one gear mesh with the teeth of one of the racks and the teeth of the other gear mesh with the teeth of the other rack.
9. The toy gun of claim 1 , further comprising a firing bay for receiving a soft projectile and wherein the nozzle interacts with the projectile to cause the projectile to be fired from the firing bay upon said emission of fluid via the nozzle.
10. A toy gun, comprising:
a body;
a chamber;
a nozzle;
a piston movable within the chamber to cause fluid in the chamber to be emitted via the nozzle;
a movable handle connected to the body; and
a gear mechanism cooperating with the handle and the piston to convert movement of the handle to lesser or greater movement of the piston;
wherein the gear mechanism comprises a first rack attached to or formed integrally with the handle to move therewith, a second rack fixed to or formed integrally with the body, and one or more gears attached to the piston and cooperating with both racks.
