A soft projectile launcher includes a launching tube including a power channel, a projectile loading channel, and a projectile exit channel connected in sequence, a projectile entry tube including a projectile entry channel connected to the projectile loading channel and configured to provide a soft projectile to the projectile loading channel, and a power assembly connected to a free end of the power channel and configured to provide power for launching the soft projectile. At least a part of at least one of the projectile entry channel, the projectile loading channel, or the projectile exit channel includes an elliptical channel.

A cocking and loading system for an air rifle utilizes a movable compression cylinder linked to the cocking arm to urge a piston into a cocked position, wherein the compression cylinder returns to a rest position urging a pellet feed tube through a magazine to load a pellet into the barrel.

A method of manufacturing an engine piston may include performing upper-body formation for forming an upper body as an upper portion of a piston body by pressing a powder-type sintered material, performing lower-body formation for forming a lower body as a lower portion of the piston body by pressing a powder-type sintered material, performing bonding for forming the piston body by providing a brazing material between the upper body and the lower body and brazing the upper body and the lower body to each other while sintering a sintered material, performing machining for removing pores from the surface of the piston body by machining the surface, and performing heat treatment for forming a passive film by performing at least one of nitriding heat treatment or oxidation heat treatment on the surface of the piston body.

A dart launcher having few but integral parts and an assembly process that is quick and easy for forming robust but inexpensive toys. The launcher may have an outer body, a safety valve and spring, a valve cap, a trigger, a piston, a launch spring, a cylinder cap and a plunger rod. The outer body includes an integral cylinder portion, a barrel portion and a trigger-mounting portion, the trigger includes an integral finger pad portion, a latch arm, a biasing portion and resilient legs. The piston includes an opening and a connector component formed around the opening to snap-fit with the piston, the cylinder cap includes an opening for the plunger rod and a connector component to connect with the cylinder portion, and the barrel portion includes a valve and mandrel support for supporting the safety valve and spring.

A structure includes a bolt body combined in a toy gun, a bullet feeding element, a high pressure air opening, an air outlet opening, an air valve assembly, a piston element, a recoil bar at one side of the bolt body, a first elastic element fit over the recoil bar, a bolt sleeve defined at one side of the bolt body and movably fit over the recoil bar, and an abutting section. When the high pressure air is input through the high pressure air opening, the air valve assembly may change a flowing direction thereof and drive the abutting section to move so as to control rearward movement of the piston element, the bolt body, and the bullet feeding element. A first elastic element that is operable to move the bolt body forward is disposed on the recoil bar outside the bolt body.

A projectile launcher that toy ball projectiles. The projectile launcher has a launch tube and a slide tube that interconnect in a telescoping manner. A handle is affixed to the free end of the slide tube. The handle is free to rotate relative the launch tube. In this manner, the handle can be rotated while the slide tube telescopes with the launch tube. A bow structure is affixed to the launch tube. The bow structure has opposing arms that extend away from the launch tube in the manner of an archery bow. An elastic bow string extends between the free ends of the bow structure arms and the handle. During use, a toy ball projectile is positioned in the launch tube. The slide tube is retracted relative the launch tube. The movement of the slide tube stretches the elastic bow string and biases the slide tube forward.
