Patent No. US10900730 (titled "Firearm Magazine Loader") was filed by Elite Tactical Systems Group Llc on Jan 3, 2020.
’730 is related to the field of firearm accessories, specifically devices designed to simplify and expedite the loading of ammunition into magazines. High-capacity magazines, particularly those for double-stack firearms, require significant force to load due to spring tension and cartridge binding. This can be time-consuming and physically demanding, leading to user fatigue and discomfort. The patent addresses the need for a magazine loader that reduces the effort and time required to load magazines, especially high-capacity double-stack magazines.
The underlying idea behind ’730 is to use a specially shaped internal chamber within the loader body to guide and rotate cartridges into the correct orientation for insertion into the magazine. This chamber features angled walls that force the cartridge to pivot as it's pushed forward, aligning it with the magazine's feed lips. This pivoting action reduces the force needed to overcome spring tension and cartridge binding, making loading easier and faster. The loader also incorporates a self-centering mechanism to accommodate magazines of varying dimensions.
The claims of ’730 focus on a firearm magazine loader comprising a body with a round positioning chamber and a magazine well. The round positioning chamber is defined by a multi-sectional front wall and a rear wall with different angles, causing the chamber to narrow and requiring the ammunition to pivot. A projection with rails and ribs extends from the body to carry ammunition into the chamber. At least one frontal positioner is included to position the magazine within the magazine well.
In practice, the user places rounds of ammunition onto the projection, which has rails designed to hold them securely. A plunger is then used to push the rounds through the round positioning chamber. As the rounds move through this chamber, the angled walls force them to rotate, aligning them with the feed lips of the magazine inserted in the magazine well. The frontal positioner ensures the magazine is properly positioned against the rear of the magazine well, further aiding in alignment and smooth loading. The loader can be made from molded plastic or other suitable materials.
Unlike traditional magazine loaders that may simply push rounds straight into the magazine, ’730 employs a controlled pivoting action to minimize the force required. The multi-sectional front and rear walls of the round positioning chamber are key to achieving this controlled rotation. The self-centering mechanism, using frontal and lateral positioners, also distinguishes this design by accommodating a wider range of magazine sizes and ensuring proper alignment, which reduces the likelihood of jams or misfeeds during the loading process.
In the mid-2010s when ’730 was filed, at a time when firearm magazines were typically manufactured with varying dimensions and tolerances, magazine loaders commonly relied on manual force to overcome spring tension and properly align ammunition with the magazine feed lips. When hardware or software constraints made the design of a universal magazine loader non-trivial, loaders often incorporated features to accommodate dimensional variations in magazines from different manufacturers.
Claims 1-20 were pending. Claims 1-20 were rejected for nonstatutory double patenting over U.S. Patent No. 10,317,154. The examiner stated that claims 1-20 were allowable over the prior art of record other than the double patenting rejection. The application proceeded to allowance, and the examiner provided a statement of reasons for allowance.
This patent contains 20 claims, with independent claims numbered 1, 10, and 17. The independent claims generally focus on a firearm magazine loader comprising a body defining a magazine well and a round positioning chamber, a projection for carrying ammunition, and variations in the shape and configuration of these components. The dependent claims elaborate on specific features and configurations of the magazine loader, such as the shape of the front and rear walls of the round positioning chamber, the inclusion of positioners, and the addition of a plunger.
