Patent Application
20170176120
The earliest known firearm was probably the fire lance which was invented in China. It used a primitive form of gunpowder with shrapnel inserted in a bamboo barrel. Eventually as improvements were made, the barrel became metal, the shrapnel was replaced with projectiles made to fit the barrel and the gunpowder was improved to maximize the explosive power. This allowed the gun to revolutionize weaponry and the sword and shield that had existed for thousands of years gave way to modern warfare.
Although these improvements allowed the gun to be more and more deadly, the firearms of the time had the major disadvantage of taking much longer than a sword to be ready for use again. Early attempts to overcome this were generally focused on multiple barrels which could be preloaded and fired in succession. This helped but also increased the weight and complexity of the gun and the weight increase limits the number of barrels you can reasonably use.
As improvements to ammunition came, the time required to place a new cartridge to be fired in a single barrel was reduced and improvements like the “repeating rifle” allowed multiple shots to be fired with very little time between reloading. In order to feed these new cartridges to the firearm, spring loaded magazines were provided that moved the cartridge into position. Today, most rifles and handguns (not revolvers) utilize a magazine with a clip that holds the ammunition and feeds it as needed. Generally this is done by using a spring of some kind to provide the biasing force to move the cartridge into a firing position within the barrel. In most firearms that use a magazine, it is necessary to load the magazine by pushing down on the biasing spring using the cartridges to be loaded. Because of this, it gets harder to push down as each cartridge is loaded. It can be difficult and awkward especially in high capacity magazines which can hold more than 10 rounds.
There is a need for a safe and easy to use magazine that allows the user to load the magazine without having to press down on the cartridges being loaded which makes further loading more difficult.
An easy loading magazine has a magazine tube with a follower that is spring biased to feed cartridges to a firearm. The follower has a follower engagement opening within it that is sized to fit the specific caliber cartridge being used in the magazine. The user places the cartridge within the follower engagement opening and uses the cartridge to force the follower down thus relieving the pressure against the cartridges to be loaded. After the cartridges are loaded within the magazine, the user removes the cartridge that was inserted in the follower engagement opening and this re-engages the follower. In one embodiment, a locking slot is provided that allows the user to temporally lock the follower in place while loading the magazine and then sliding the cartridge back to release the follower.
Other features and advantages of the instant invention will become apparent from the following description of the invention which refers to the accompanying drawings.
In the following detailed description of the invention, reference is made to the drawings in which reference numerals refer to like elements, and which are intended to show by way of illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments may be utilized and that structural changes may be made without departing from the scope and spirit of the invention.
Referring to
A follower engagement opening 125 is provided to allow a user to insert a cartridge 120 within to manually force spring 135 down without having to push down on a cartridge 120 to move follower 115 down. The user simply places cartridge 120 within follower engagement opening 125 and then moves follower 115 down along a track opening 132 by pushing on cartridge 120 which temporarily relieves the biasing force on follower 115 which allows the user to simply feed cartridges 120 within easy loading magazine 100. Track opening 132 is provided to allow cartridge 120 to move down along magazine tube 110. Once loaded, the user removes cartridge 120 which re-engages follower 115 which feeds cartridges 120 as in a conventional magazine.

Now referring to
Magazine tubes 110 and 210 respectively; may be made of plastic, steel or other suitable material as is known in the art. The springs used to provide the biasing force may be tape, coil, leaf, wire or any other suitable spring type as is known in the art.
Follower engagement openings 125 and 225 and follower engagement slot opening 228 respectively, are made to fit the specific caliber of cartridge being used by the corresponding magazine. This allows the user to operate the magazine without any special tools other than the proper ammunition that fits within the magazine.
Referring to
Easy loading magazine 100 is made from sheet metal or any suitable material such as, but not limited to plastic, composite or other suitable material as is known in the art. The specific configuration of the feeding mechanism that feeds the ammunition to the specific firearm being used is understood to match the selected firearm and is well known in the art. The instant invention is understood to be adaptable to any firearm that uses a magazine and can easily be made available as an after-market option since the instant magazine does not add any incompatible parts that would interfere with the normal insertion of a typical magazine.
Although the instant invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art.
