Abstract
An air operated toy gun for successively launching a plurality of projectiles is disclosed. Said gun utilizes a movable air nozzle for successive engagement with a plurality of projectile launching barrels. The gun may be used with darts or other projectiles adapted to form a seal with the launching barrels.
Claims20
An air operated toy gun comprising:
- a frame;
- an air chamber carried on said frame;
- said chamber having an air outlet path adapted to conduct airflow from said chamber through a nozzle;
- said nozzle being movably carried on said frame for motion between a cocking position and a firing position;
- a magazine movably carried on said frame and comprising a plurality of barrels in spaced relationship;
- each of said barrels comprising an elongated passageway open at both ends;
- said magazine movable on said frame whereby said barrels are selectively alignable with said nozzle to allow airflow from said nozzle through said passageway;
- a piston in said air chamber having a shape complementary to said air chamber;
- means for propelling said piston through a firing stroke within said chamber to displace air under pressure from said chamber through said nozzle;
- means urging said nozzle into said firing position during said piston firing stroke to engage said nozzle with a selected barrel, said barrel and said nozzle being adapted to form a substantially airtight seal with each other;
- each said barrel adapted to carry a projectile and to form a substantially airtight seal with said projectile to normally prevent airflow through said barrel;
- said airtight seal between said nozzle and said barrel being able to withstand a higher magnitude of air pressure than said airtight seal between said projectile and said barrel such that application of elevated air pressure within said barrel will cause breakdown of said seal between said projectile and said barrel prior to a substantial breakdown of said seal between said nozzle and said barrel for the desired result of said projectile being ejected from said barrel by force of said air pressure.

An air operated dart gun comprising:
- a frame;
- an elongated air cylinder movably carried on said frame for forward and reverse travel between a cocking position and a firing position;
- said air cylinder comprising a nozzle to allow air to exit said cylinder;
- a piston movably carried in said air cylinder;
- a spring normally biasing said piston within said cylinder toward said nozzle;
- a magazine movably carried on said frame;
- said magazine comprising a plurality of dart barrels in spaced relationship;
- said barrels being selectively alignable with said nozzle of said air cylinder;
- one end of each said barrel being adapted to be engageable with said nozzle to form a substantially airtight seal when said air cylinder is in said firing position;
- the other end of each said barrel being adapted to receive a projectile so as to form a substantially airtight seal between said barrel and said projectile;
- means for drawing said piston rearward away from said magazine and against said spring bias;
- friction of said rearward moving piston within said cylinder dragging said cylinder rearward to said cocking position to disengage said nozzle from said selected barrel;
- means for drawing said piston further rearward to engage a latch, said latch holding said piston against said spring bias;
- a trigger for releasing said latch to allow said spring bias to propel said piston forward within said cylinder toward said nozzle;
- said cylinder being urged forward toward said firing position by friction of said piston moving within whereby said nozzle is forcibly engaged with said selected barrel;
- said piston furthermore displacing air from said cylinder through said nozzle to eject said projectile from said selected barrel.
