Description

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

This invention was not federally sponsored.

BACKGROUND OF THE INVENTION

The present invention is in the technical field of firearms. More particularly, the present invention is in the technical field of ammunition magazine base plates. More specifically, the present invention is in the field of ammunition magazine base plates that can attach and detach more than one magazine.

Since the inception of the guns, shooters have striven to improve the efficiency of re-loading. This was sensible for the hunter to avoid losing game, for the soldier to protect against his enemy, and for the farmer to defend his person and property. The revolver and repeating rifle improved upon the ball and black power by enabling the loading of multiple rounds, either in a rotating cylinder that could fire six bullets before re-loading was necessary, or into a captured enclosure in the rifle. The pistol improved upon the revolver by utilizing a magazine that can hold sometimes as many as 20 rounds, although 10 round magazines are by far the most common. For rifles one can find magazines that hold much larger numbers of rounds.

Today, many states have instituted laws that limit the maximum number of rounds in a magazine to ten, and in some cases less than ten. The present invention helps individuals in regulated states as well as in unregulated states by securely fixing two magazines together at the base of the magazine by means of the present invention. This doubles the amount of ammunition attached and carried in a weapon. For some individuals, including professional and amateur competitive shooters, individuals protecting their families and property, military and law enforcement, the number of rounds in a magazine, and magazine replacement speed, can be critical.

The present invention provides for the attachment of two magazines of any capacity to a single base plate. A typical magazine includes the magazine body, a follower, a spring, an insert or locking plate and a base plate. The locking plate mechanism fixes into the base plate to prevent the magazine from disassembling while in use. The locking mechanism on a typical base plate cannot be released without easy access to the bottom of the magazine. Because of this design it has not previously been possible to connect two magazines at the base plates. The present invention employs a locking mechanism that can be operated without requiring direct access to the bottom of the magazines, and allows a user of the invention to benefit from being able to use the bullets from two magazines in a manner significantly more efficient that having to find a second magazine and insert it.

OBJECTS OF THE INVENTION

It is an object of the present invention to provide a method for replacing the base plate of a typical single magazine with a base plate that can accommodate a magazine attached to one side of the base plate and a second magazine attached to the opposing side of the base plate. Additionally, the present invention will allow one to remove one or both magazines with relative ease, with the use of a commonly available tool.

The present embodiment is a magazine locking base plate comprising a main body, a drive shaft, a paddle and an internal retaining ring. The paddle is inserted into the paddle slot then the drive shaft is inserted into the shaft hole in the main body. The drive shaft passes through, and is retained, in the center of the paddle. The paddle and drive shaft are held in the main body by the retaining ring, where the retaining ring expands into a retaining ring groove in the main body to “lock” the paddle and drive shaft. The main body incorporates a base flange slot on both the top and bottom of the present embodiment that allow a magazine assembly to be inserted by sliding the base flange of a magazine body into the base flange slot on both sides of the main body. The magazine assembly is retained by its flange in the main body flange slot of the present embodiment. To lock a magazine to the present embodiment the drive shaft is rotated, releasing the locking plate of the magazine to engage the base plate

With the present invention attached to a magazine assembly, the magazine assembly can be unlocked and the present embodiment removed by rotating the drive shaft in the opposite direction using a commonly available tool, thereby rotating the paddle and raising the locking plates free of the base plate, and allowing the magazines to be removed from the base flange in the main body.

The foregoing is a broad outline of the purpose, features and functions of the present invention in order (i) to facilitate a fuller understanding of the detailed description herein, and (ii) that the present contribution to the art may be better appreciated. There are additional features of the present invention that will be described below, and which will form the subject matter of the claims appended hereto.
