  • Patent number: 11340037
    Abstract: A toy projectile launcher for launching projectiles, e.g, toy foam darts, from a detachable hopper. An agitating member inside the hopper enables the orderly descent of the projectiles within the hopper. A hopper cover has a collapsible ceiling with nested members and a ceiling plate to maintain the projectiles toward the bottom of the hopper. First and second catches coupled to the ceiling plate respectively engage openings in hopper walls to prevent the ceiling plate from collapsing into the cover when the hopper cover is closed. Where there are multiple vertically-spaced-apart openings in the hopper walls, the first and second catches may disengage from respective first openings, and then engage lower, second openings in the hopper walls, as the number of projectiles in the hopper drops and the ceiling plate descends in the hopper. A rotating gear advances projectiles from the firing chamber to flywheels for launch.

  • Patent number: 10393457
    Abstract: The present invention is an ammunition magazine, preferably made of a reinforced polymer, utilizing a structurally enhancing ridge, angular guide rails and a follower made to interface with said guide rails to reduce wobble. The preferred embodiment also features a protective cover that distributes forces from the spring to more structurally sound areas of the magazine, thus reducing feed end splay, and an ammunition indication system comprised of at least one window and a noticeable marker on the follower spring. The follower and magazine casing are also designed to interface to prevent the follower from popping out of the feed end and the floor plate of the magazine utilizes a locking plate and sliding relationship between the floor plate, locking plate and magazine to secure the floor plate onto the magazine casing. The cover features built in tools for, among other things, unloading and disassembling the magazine.

  • Patent number: 10337809
    Abstract: A magazine for storing cased telescoped (CT) cartridges. The magazine includes vertically extending side-wall ribs that project inwards into a loading channel. The side-wall ribs are positioned in alignment with a circumferential groove in each CT cartridge. The side-wall ribs prevent a backwards oriented CT cartridge from being pushed from the loading position through the loading channel into a body of the magazine. A moveable lip at the top of the magazine may move out of the way when the magazine is attached to a firearm, to allow the CT cartridge located in the loading position to be fed vertically out of the top of magazine. Each CT cartridge may include a thermal protective insert that provides thermal insulation from heat emanating from a barrel of a firearm when the CT cartridge is located in a chamber of the firearm.
