US12345500 - High performance launcher of short projectiles with piston nozzle spring

A toy projectile launcher having a projectile container, a cocking slide, and a housing is disclosed. The projectile container contains projectile holders that are adapted to hold a projectile, such as a foam dart. The cocking slide can be moved forward and backward. The housing houses a launch barrel and an air piston assembly. When the cocking slide is moved backward the air piston barrel moves backward, and a projectile holder is moved into a firing position. The foam dart is held in place by a resilient stopper. When the cocking slide is moved forward an air nozzle engages a surface of the resilient stopper and advances through the projectile holder, pushing the foam dart into the launch barrel. An airtight seal is formed between the launch barrel and air piston assembly.

The patent describes a toy projectile launcher that utilizes a cocking slide mechanism to load and launch foam darts from a container through a launch barrel using an air piston assembly. The design includes resilient stoppers to secure projectiles and ensure an airtight seal during operation, enhancing the efficiency of the launching process.

Claim 1

A toy projectile launcher, comprising: a projectile container containing a plurality of projectile holders, each projectile holder configured to contain a loaded projectile, wherein the projectile container includes a plurality of resilient projectile stoppers, wherein each resilient projectile stopper abuts a portion of a respective projectile loaded in a respective projectile holder; a cocking slide that is adapted to be moved forward and backward; and a housing, the housing having disposed therein: a launch barrel; an air piston assembly, the air piston assembly including an air piston barrel having an air nozzle disposed on a front portion thereof, a plunger element, and a compression spring; wherein the projectile container, the launch barrel, and the air piston assembly are each coupled to the cocking slide; wherein, when the cocking slide is moved backward from a forward position to a backward position: a front portion of the air piston barrel moves backward and pushes the plunger element to compress the compression spring against a rear wall of the housing, wherein the plunger element and compression spring are held in place by a latching mechanism; and a projectile advancement mechanism engages the projectile container and advances a next projectile holder containing a loaded projectile into a firing position in front of the air piston barrel; and wherein, when the cocking slide is moved forward from the backward position to the forward position: the front portion of the air piston barrel moves forward, forming an internal air chamber between the front portion of the air piston barrel and the plunger element; and the air nozzle moves forward to form an airtight seal between the air piston barrel and the launch barrel, wherein a front portion of the air nozzle engages a trailing surface of one of the plurality of resilient projectile stoppers, wherein, upon said engagement by the front portion of the air nozzle, the one of the plurality of resilient projectile stoppers flexes outward to allow the front portion of the air nozzle to extend through the next projectile holder, wherein the front portion of the air nozzle pushes the loaded projectile in the next projectile holder from the next projectile holder into the launch barrel, and wherein the front portion of the air nozzle connects to the launch barrel to form an airtight seal between the air piston barrel and the launch barrel. a projectile container containing a plurality of projectile holders, each projectile holder configured to contain a loaded projectile, wherein the projectile container includes a plurality of resilient projectile stoppers, wherein each resilient projectile stopper abuts a portion of a respective projectile loaded in a respective projectile holder; a cocking slide that is adapted to be moved forward and backward; and a housing, the housing having disposed therein: a launch barrel; an air piston assembly, the air piston assembly including an air piston barrel having an air nozzle disposed on a front portion thereof, a plunger element, and a compression spring; a launch barrel; an air piston assembly, the air piston assembly including an air piston barrel having an air nozzle disposed on a front portion thereof, a plunger element, and a compression spring; wherein the projectile container, the launch barrel, and the air piston assembly are each coupled to the cocking slide; wherein, when the cocking slide is moved backward from a forward position to a backward position: a front portion of the air piston barrel moves backward and pushes the plunger element to compress the compression spring against a rear wall of the housing, wherein the plunger element and compression spring are held in place by a latching mechanism; and a projectile advancement mechanism engages the projectile container and advances a next projectile holder containing a loaded projectile into a firing position in front of the air piston barrel; and a front portion of the air piston barrel moves backward and pushes the plunger element to compress the compression spring against a rear wall of the housing, wherein the plunger element and compression spring are held in place by a latching mechanism; and a projectile advancement mechanism engages the projectile container and advances a next projectile holder containing a loaded projectile into a firing position in front of the air piston barrel; and wherein, when the cocking slide is moved forward from the backward position to the forward position: the front portion of the air piston barrel moves forward, forming an internal air chamber between the front portion of the air piston barrel and the plunger element; and the air nozzle moves forward to form an airtight seal between the air piston barrel and the launch barrel, wherein a front portion of the air nozzle engages a trailing surface of one of the plurality of resilient projectile stoppers, wherein, upon said engagement by the front portion of the air nozzle, the one of the plurality of resilient projectile stoppers flexes outward to allow the front portion of the air nozzle to extend through the next projectile holder, wherein the front portion of the air nozzle pushes the loaded projectile in the next projectile holder from the next projectile holder into the launch barrel, and wherein the front portion of the air nozzle connects to the launch barrel to form an airtight seal between the air piston barrel and the launch barrel. the front portion of the air piston barrel moves forward, forming an internal air chamber between the front portion of the air piston barrel and the plunger element; and the air nozzle moves forward to form an airtight seal between the air piston barrel and the launch barrel, wherein a front portion of the air nozzle engages a trailing surface of one of the plurality of resilient projectile stoppers, wherein, upon said engagement by the front portion of the air nozzle, the one of the plurality of resilient projectile stoppers flexes outward to allow the front portion of the air nozzle to extend through the next projectile holder, wherein the front portion of the air nozzle pushes the loaded projectile in the next projectile holder from the next projectile holder into the launch barrel, and wherein the front portion of the air nozzle connects to the launch barrel to form an airtight seal between the air piston barrel and the launch barrel.
