US12405076 - Unit for loading ammunition into box magazines of small arms

This patent describes a loading unit designed for quickly replenishing box magazines of small arms, featuring a pull-rod device and a follower mechanism that utilizes springs and catch protrusions for efficient ammunition loading. The innovative design aims to streamline the reloading process while ensuring the components work cohesively to maintain a consistent spring height during operation.

Claim 1

1. A unit for loading ammunition into small arm box magazines which is constituted by a pull-rod device and a magazine having a housing with an upper slot for moving ammunition below which a follower with a centrally located hole is located, wherein the follower is seated on a spring which rests with its lower end on a bottom plate having a centrally located hole and rests on a base cover having a central hole, wherein the rigid pull-rod device, slidable into the housing, is located in the hole of the follower, the hole of the bottom plate and the hole of the base cover and has movable catch protrusions preferably located in the zone of the upper extremity of the body, protruding beyond the outline of the body, detachably connected to the surface of the follower, closing the spring of the follower from above and controlled by a slider operated by a spring, the seat of which is located inside the body, and retention protrusions located below the catch protrusions in the zone of the upper extremity of the body, wherein the retention protrusions, after compression of the spring of the follower, are retained by a movable element blocking the coils of the spring of the follower from below, thereby they close the compressed spring of the follower from below and co-create a preferable coupling mechanism that moves along the longitudinal axis of the magazine, and the height of the compressed spring of the follower, when it is moved, is an approximately constant value, whereby the follower, the follower spring, the movable element blocking the coils of the spring of the follower from below and the pull-rod device constitute the coupling mechanism.
