US12416466 - Launcher of short projectiles with detachable barrel

A toy projectile launcher having a housing, a projectile container, a cocking slide, an air piston assembly, a barrel interface section, and a detachable launch barrel is disclosed. The projectile container is adapted to hold projectiles, such as foam darts. The cocking slide can be moved for-ward and backward. When the cocking slide is moved backward the air piston barrel moves backward, and a projectile is moved in front of the air piston assembly. When the cocking slide is moved forward, the projectile is pushed into the barrel interface section by an air nozzle disposed on the front of the air piston assembly. A first airtight seal is formed between the air piston assembly and the rear of the foam dart, and a second airtight seal is formed between the barrel interface section and the detachable launch barrel.

The patent describes a toy projectile launcher featuring a detachable launch barrel, a cocking slide, and an air piston assembly that propels foam darts. The design includes airtight seals to ensure efficient operation when launching projectiles from the housing.

Claim 1

A toy projectile launcher, comprising: a housing; a projectile holder disposed within the housing and configured to contain a plurality of projectiles; a barrel interface section disposed at a front portion of the housing; an air piston assembly disposed within the housing and including an air piston barrel having an air nozzle disposed on a front portion thereof, a plunger element, and a compression spring; a cocking slide that is adapted to be moved forward and backward relative to the housing, the projectile holder and the air piston assembly being coupled to the cocking slide; and a first detachable launch barrel that is adapted to (i) engage and attach to the barrel interface section; and (ii) disengage and detach from the barrel interface section; wherein, when the cocking slide is moved backward from a forward position to a backward position, the air piston barrel moves backward and pushes the plunger element to compress the compression spring against a rear wall of the housing; wherein, when the cocking slide is moved forward from the backward position to the forward position: the air piston barrel moves forward, forming an internal air chamber between a front portion of the air piston barrel and the plunger element; and the air nozzle moves forward to push one of the plurality of projectiles from the projectile holder into the barrel interface section to form a first airtight seal between the air piston barrel and the barrel interface section; and wherein, when the first detachable launch barrel is attached to the barrel interface section, a second airtight seal is formed between the air nozzle and the first detachable launch barrel. a housing; a projectile holder disposed within the housing and configured to contain a plurality of projectiles; a barrel interface section disposed at a front portion of the housing; an air piston assembly disposed within the housing and including an air piston barrel having an air nozzle disposed on a front portion thereof, a plunger element, and a compression spring; a cocking slide that is adapted to be moved forward and backward relative to the housing, the projectile holder and the air piston assembly being coupled to the cocking slide; and a first detachable launch barrel that is adapted to (i) engage and attach to the barrel interface section; and (ii) disengage and detach from the barrel interface section; wherein, when the cocking slide is moved backward from a forward position to a backward position, the air piston barrel moves backward and pushes the plunger element to compress the compression spring against a rear wall of the housing; wherein, when the cocking slide is moved forward from the backward position to the forward position: the air piston barrel moves forward, forming an internal air chamber between a front portion of the air piston barrel and the plunger element; and the air nozzle moves forward to push one of the plurality of projectiles from the projectile holder into the barrel interface section to form a first airtight seal between the air piston barrel and the barrel interface section; and the air piston barrel moves forward, forming an internal air chamber between a front portion of the air piston barrel and the plunger element; and the air nozzle moves forward to push one of the plurality of projectiles from the projectile holder into the barrel interface section to form a first airtight seal between the air piston barrel and the barrel interface section; and wherein, when the first detachable launch barrel is attached to the barrel interface section, a second airtight seal is formed between the air nozzle and the first detachable launch barrel.
