1. Field Of Invention
The present disclosure relates generally to an improved firearm and ammunition magazine system which allows users, such as police officers, state and federal agents and military personnel, to more quickly load and reload ammunition magazines in darkness.
2. Brief Description Of The State Of Knowledge In The Art
The use of hand-held firearms by law enforcement officers, and armed security guards, is well known in the art.
In
As shown, the conventional ammunition magazine 4 comprises: a hollow body 4A having a bottom opening 4B and a top opening 4C a top opening in communication with the barrel 2; a base plate 4D fixed stationary with respect to the hollow body 4A and closing off the bottom opening 4B; a movable platform 4E installed within the hollow body 4A and capable of sliding up and down therewithin; a spring 4F disposed between the movable platform 4E and the base plate 4B. In general, the hollow body is adapted for storing a round of ammunition (i.e. bullets) supported on the movable platform and extending up to the top opening.
During firearm operation, the movable platform and round of ammunition are pushed towards the top opening 4C, by virtue of the upwardly-directed biasing forces acting on the movable platform 4E and generated by the spring 4F installed between the movable platform 4E and the base plate 4B. Such forces assist in advancing the round of ammunition out of the magazine body 4A and through the top opening 4C during firearm operation. The round of ammunition (i.e. bullets) contained within the magazine is often called a cartridge, and is loaded, bullet by bullet, from the magazine into the firearm in a manner known in the art.
During night-time gun-fight, it can be difficult to find extra ammunition magazines to snap into ones firearm during reloading operations. Also, it is easy for the firearm user to load the ammunition magazine into the wrong direction of the handle portion of a firearm, as shown in

In order to more fully understand the Objects, the following Detailed Description of the Illustrative Embodiments should be read in conjunction with the accompanying figure Drawings in which:
Referring to the figures in the accompanying Drawings, the various illustrative embodiments of the present invention will be described in great detail, wherein like elements will be indicated using like reference numerals.
In general, the present invention teaches the application of photo-luminescent (i.e. glow-in-the-dark) material to the base plate portion of a weapon/firearm ammunition magazine so as to enable the firearm user, such as a police officer, state or federal agent or military personnel, to quickly access an ammunition magazine in dark and low-lighting level environments, accurately determine its spatial orientation, and properly insert (i.e. load) the magazine into the firearm in a correct manner, and then retrieve the spent magazine in total darkness, remove (i.e. unload) it from the firearm, and then reload another loaded magazine, quickly without error or reloading errors or delays.
Photo-luminescent materials are luminous materials which can absorb and store energy of various ultraviolet and other wavelengths, and then release (i.e. emit) visible illumination (i.e. light) energy in dark environments.
While various types of photo-luminescent materials can be used to practice the present invention, a preferred photo-luminescent material would be based on strontium aluminate (SRA, SrAl, SrAl2O4) which when activated with a suitable rare earth element dopant (e.g. Europium—SrAl2O4:Eu), acts as a photo-luminescent phosphor having a long persistence of Phosphorescence, a specific type of photoluminescence related to fluorescence.
A strontium aluminate based luminous pigment (SrAl2O4:Eu) is a light-yellow powder which turns to green color after activated by visible light. This a particular luminous material has many advantages which make currently it a preferred material for practicing the present invention, namely: short activation (i.e. photo-recharging) time; long afterglow time (i.e. decay time) of 12 or more hours; long lifetime (up to 10 years); high brightness characteristics; non-toxic; harmless; non-radioactive; non-flammable; and non-explosive etc. Also, the photo-luminous material SrAl2O4:Eu can be used in many transparent or translucent media such as plastic, paint, glaze, ink, glass, printing slurry etc. to produce the photo-luminous magazine base plates according to the principles of the present invention.
There a numerous commercial sources available for the photo-luminescent materials (i.e. tape, paint, powder, pigment, etc) used to practice the method and apparatus of the present invention taught herein.
In accordance with the principles of the present invention, photo-luminescent materials (i.e. pigments) of any color (i.e. emission wavelength) can be used to practice the present invention, and various methods of integrating such photo-luminescent material into the base plate portion of a firearm magazine can be used. Such method will be specified in detail below.
In the case where the magazine base plate 4D″′ is made from transparent or translucent plastic material, then this plastic material can be mixed with a suitable photo-luminescent (i.e. glow-in-the-dark) pigment described hereinabove to make a photo-luminescent pattern 65A, 65B within the finally manufactured magazine base plate 4D″′.
Alternatively, a transparent or translucent plastic material containing a photo-luminescent pigment material described above can be co-molded with an opaque (e.g. black colored) plastic material, using co-molding techniques known in plastic co-molding art, to make the plastic magazine base plate 4D″′ having a desired photo-luminescent pattern 65A, 65B formed in the manufactured magazine base plate, in accordance with the principles of the present invention.
Typically, after a single photo-recharging operation, involving exposing the photo-luminescent base plate 4D″′ to daytime light levels for a few minutes or so, the photo-luminescent base plate 4D″′ will continue to emit visible illumination for 12 or more hours.
As illustrated in
As shown in
The present invention can be practiced in a wide variety of ways and modes.
The hand-held firearms with photo-luminescent magazines 40, 50, 60 described above can be manufactured by licensed firearm manufacturers, and sold to firearm users as an after-market product.
The photo-luminescent magazines of the present invention 40, 50, 60 described above can be manufactured by licensed ammunition magazine manufacturers, and sold to firearm users as an after-market product.
The photo-luminescent magazine base plates of the present invention 4D′, 4D″, 4D″′ described above can be manufactured by licensed third-party equipment manufacturers, and sold as an after-market product to firearm users who can install the photo-luminescent base plates 4D′, 4D″, 4D″′ in currently-owned ammunition magazines, to transform conventional magazines into photo-luminescent magazines 40, 50, 60, respectively, in accordance with the principles of the present invention.
Any of the photo-luminescent ammunition magazines of the present invention described above 40, 50 60 can be used to practice a new and improved a method of assisting a user in correctly loading and reloading ammunition magazines into a hand-held firearm 100 in the darkness.
The first step of the method involves supplying a hand-held firearm 100 to a user (e.g. a police officer, state or federal agent, or military personnel) to be worn on the person thereof.
The second step involves supplying the user with an open-top ammunition holster 150 as shown in
The third step involves the user loading two of the ammunition magazines 40, 50, 60 into the open-top ammunition holster 150. Any remaining magazines can be stored in a supply case or other carrying device.
While the ammunition magazines 40, 50, 60 are supported in the open-top ammunition holster 150, the photo-luminescent elements on the magazines are photo-recharged by ambient sources of illumination (e.g. the Sun during day-time and high-intensity lighting sources during the night-time).
Then, while the firearm user is in darkness conditions or otherwise in dark non-illuminated environments, visible illumination is brightly emitted from the photo-luminescent base plates of the ammunition magazines of the present invention, supported in the open-top ammunition holster 150. Such brightly glowing indications from the photo-luminescent ammunition magazines 40, 50, 60 help the user in quickly determining the correct direction that bullets in the hollow body of the magazine should be loaded into the barrel of the hand-held firearm 100, preventing fumbling or incorrect reloading operations, in an unprecedented manner.
Modifications That Come To MindThe illustrative embodiments described above show hand-held pistol-style firearms being provided with ammunition magazines equipped with photo-luminescent base plates that allow for quick, safe and correct loading of the magazines in darkness or otherwise under very-low ambient illumination conditions. It is understood, however, that such photo-luminescent techniques can be practiced in other types of hand-held firearms, with excellent results.
Variations and modifications to the photo-luminescent ammunition magazines and base plates of the present invention readily occur to those skilled in the art having the benefit of the present disclosure. All such modifications and variations are deemed to be within the scope of the accompanying Claims.
