US12710246 - Toy launch apparatus with momentum feature and concentric piston

An air launch apparatus includes a frame, a grip, and a plurality of sidewalls and also includes a hollow substantially cylindrical barrel having a central longitudinal axis. The air launch apparatus further includes a piston disposed substantially concentric with the barrel. The piston is configured to move longitudinally along the outer surface of the barrel in directions parallel to the longitudinal axis. The air launch apparatus also includes a nut that is configured to engage the piston as a front block carrying the nut is drawn rearward toward a user, and to hold the piston stationary relative to the front block while so engaged. A plunger, fixedly connected to the piston, is configured to move with the piston. Movement of the piston and plunger, forward during cocking draws air into a volume within an air chamber of the air launch apparatus.

The patent describes an air launch apparatus designed for toy projectiles, featuring a cylindrical barrel and a concentric piston that moves longitudinally to draw air into an internal chamber during cocking. The apparatus includes a frame, grip, and a nut mechanism that allows the piston to be engaged and moved in conjunction with a front block.

Claim 1

1 . An assembly, comprising: a frame including a grip; a first sidewall; a second sidewall opposite the first sidewall; a front block fixed to the first and second sidewalls; a substantially cylindrical barrel fixed relative to the frame and defining a central longitudinal axis; a piston concentric with and movable along an outer surface of the barrel; and a nut, supported by the front block, the nut configured to: releasably mate with the piston, and cause movement of the piston together with the front block, in a direction parallel to the longitudinal axis, while the nut is releasably mated with the piston. a frame including a grip; a first sidewall; a second sidewall opposite the first sidewall; a front block fixed to the first and second sidewalls; a substantially cylindrical barrel fixed relative to the frame and defining a central longitudinal axis; a piston concentric with and movable along an outer surface of the barrel; and a nut, supported by the front block, the nut configured to: releasably mate with the piston, and cause movement of the piston together with the front block, in a direction parallel to the longitudinal axis, while the nut is releasably mated with the piston. releasably mate with the piston, and cause movement of the piston together with the front block, in a direction parallel to the longitudinal axis, while the nut is releasably mated with the piston.
