US12613076 - Pneumatic launching apparatus employing barrel cam driving pathways and methods

Launcher apparatus and methods of a toy projectile blaster piston air compression element and breech bolt operating through a barrel cam peripheral surface with a cylinder cam pathway track and piston cam pathways for driving contact and respective piston and cylinder timings. The barrel cam is rotatably disposed. Piston and cylinder follower ends contact the barrel cam pathways generating fluid communication to outwardly launch received projectile rounds. The breech can receive projectiles with the breech bolt of the air compression element extending into the breech to position a received projectile through the barrel seal, and a source of rotary motion or forward strokes and back strokes fires the projectiles.

The patent describes a pneumatic toy launching apparatus that utilizes a barrel cam assembly to drive a piston and cylinder mechanism for launching projectiles through an air compression system. It includes features such as a breech bolt for positioning projectiles and a mechanism for turning the barrel cam to facilitate the launching process.

Claim 1

1 . A toy launching apparatus, comprising: a firing mechanism housing; a projectile launching barrel; an air compression element comprising a cylinder and an elongated breech bolt, with the cylinder having a cylinder tracking end, the breech bolt having a proximal end at the cylinder and a breech bolt channel extending therethrough for fluid communication from the cylinder through the breech bolt for expelling compressed air from a distal end of the breech bolt, a breech spring being connected to and extending with the air compression element; a piston slidably received at the cylinder of the air compression element, with the piston having a piston tracking end; a barrel cam assembly with at least one rotatably disposed peripheral surface with a cylinder cam pathway track and piston cam pathway track, the piston tracking end at the piston cam pathway track, and the cylinder tracking end at the cylinder cam pathway track; a breech at the firing mechanism housing including at least one barrel seal aligned with the projectile launching barrel, the breech being capable of receiving one or more projectiles with the breech bolt of the air compression element capable of extending into the breech to position a received projectile through the barrel seal; and a mechanism for turning the barrel cam assembly. a firing mechanism housing; a projectile launching barrel; an air compression element comprising a cylinder and an elongated breech bolt, with the cylinder having a cylinder tracking end, the breech bolt having a proximal end at the cylinder and a breech bolt channel extending therethrough for fluid communication from the cylinder through the breech bolt for expelling compressed air from a distal end of the breech bolt, a breech spring being connected to and extending with the air compression element; a piston slidably received at the cylinder of the air compression element, with the piston having a piston tracking end; a barrel cam assembly with at least one rotatably disposed peripheral surface with a cylinder cam pathway track and piston cam pathway track, the piston tracking end at the piston cam pathway track, and the cylinder tracking end at the cylinder cam pathway track; a breech at the firing mechanism housing including at least one barrel seal aligned with the projectile launching barrel, the breech being capable of receiving one or more projectiles with the breech bolt of the air compression element capable of extending into the breech to position a received projectile through the barrel seal; and a mechanism for turning the barrel cam assembly.
