Abstract
Leaf springs for use in a firearm magazine are described. The leaf springs comprising an inner edge, an outer edge, and a channel, and configured to facilitate movement of cartridges within a feed tower of the firearm magazine. The leaf springs can be in a flexed or unflexed position, wherein downward movement of the cartridges in the feed tower outwardly flex the leaf springs into the flexed position to facilitate downward translation of the cartridges by forcing the inner edge of the leaf springs away from the cartridges, and in the unflexed position, the inner edge of the leaf springs is parallel or substantially parallel to an edge of the cartridges in the feed tower.
Claims19
A firearm magazine, comprising:
- a body;
- and
- a feed tower configured to house one or more cartridges, the feed tower comprising:
- a feed end;
- opposite
- a base end, and
- one or more leaf springs positioned within the feed tower,
- wherein the one or more leaf springs each comprise an inner edge adjacent at least a portion of the one or more cartridges and an outer edge between the inner edge and the feed tower,
- wherein the one or more leaf springs are each configured to flex between an unflexed position and a flexed position,
- wherein, in the flexed position, the inner edge is displaced towards the outer edge to provide expansion room for at least one cartridge in the one or more cartridges;
- and
- wherein the body is coupled to the base end of the feed tower and is configured to receive the one or more cartridges from the one or more leaf springs.
A leaf spring system, comprising:
- one or more leaf springs, each of the leaf springs comprising an inner edge adjacent at least a portion of a stack of cartridges in a feed tower, and an outer edge between the inner edge and the feed tower;
- wherein the one or more leaf springs are each configured to flex between an unflexed position and a flexed position,
- wherein, in the flexed position, the inner edge is displaced towards the outer edge to provide expansion room for at least one cartridge in the stack of cartridges,
- wherein the one or more leaf springs are positioned closer to a base end of the feed tower than to a feed end of the feed tower,
- wherein the base end is opposite the feed end, and
- wherein the base end is directly coupled to a body of a firearm magazine.
A firearm magazine, comprising:
- a feed tower configured to house one or more cartridges in a round stack, and
- one or more leaf springs positioned within the feed tower,
- wherein the one or more leaf springs are each configured to flex between an unflexed position and a flexed position,
- wherein, in the flexed position, the one or more leaf springs are configured to increase expansion room for the round stack within the feed tower;
- and
- wherein a body is coupled to a base end of the feed tower and is configured to receive the one or more cartridges from the one or more leaf springs.
