Abstract
A toy gun includes a housing, a forwardly biased plunger assembly in the housing, first and second rack gears in the housing, and a transmission gear assembly in the housing. The transmission gear assembly is operative for communicating rearward movement of the second rack gear to the first rack gear in order to move the first rack gear and the plunger assembly into rearward cocked positions in the housing. The transmission gear assembly is adapted so that once the first rack gear and the plunger assembly have been moved to the cocked positions thereof in housing, the second rack gear is freely movable without interference from the transmission gear assembly and the first rack gear, and so that the first rack gear and the plunger assembly are freely releasable to the uncocked positions for causing the plunger assembly to produce a blast of compressed air in order to launch a projectile from the housing.
