DETAILED DESCRIPTION

The following discussion provides many example embodiment/s of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.

As used herein, and unless the context dictates otherwise, the term “coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously.

All figures show only approximate representations of the components of the system/s and may not be accurate in scale and/or positions.

FIG. 1 is a rear-right-bottom isometric view of an embodiment of a RAMRS with a Magazine 2 locked into a firearm Grip Frame 1.

FIG. 2 is a same view as FIG. 1 but with Grip Frame 1 cutaway in half (for illustrative clarity).

FIG. 3 is a same view as FIG. 2 but without the entire Grip Frame (for illustrative clarity) showing only Magazine 2 and RAMRS in a “Magazine Secured State”.

FIG. 4 is a detailed view of Section A of FIG. 3. Magazine 2 is secured/locked by the RAMRS. A Magazine Catch 7 of a Right Thumb Actuator 4 is engaged with a Catch Divot 3 of Magazine 2.

FIG. 5 is a rear view of FIG. 3.

FIG. 6 is a detailed view of Section B of FIG. 5. Right Thumb Actuator 4 further comprises a Right Thumb Button 6. Left Thumb Actuator 8 further comprises a Left Thumb Button 10.

FIG. 7 is a same view as FIG. 5 but without the Magazine (for illustrative clarity) showing an assembled RAMRS in the Magazine Secured State.

A Biasing Force Means 16 (a spring in this embodiment) biases Right Thumb Actuator 4 in a First (−X [to the left in these illustrations]) Direction. A Right Thumb Actuator Cam Face 5 transfers the biasing force via communication with a Bottom (star labeled for illustrative purposes) Lobe 15 of a Reciprocating Cam 13 which is nestled into a semicircular Cam Rotation Divot 12 of a Reciprocating Cam Bracket 11. Reciprocating Cam Bracket 11 further comprises a Wedge (17) which utilizes the force of the Biasing Force Means to wedge/anchor the Bracket into known (and thus not illustrated) features of the hollow Magazine Well of the Grip Frame. The biasing force is subsequently transferred in an Opposite (+X) Direction via a Top Lobe 14 (triangle labeled for illustrative purposes) of the Reciprocating Cam 13 to a Left Thumb Actuator Cam Face 9 of Left Thumb Actuator 8.

Interference features (4/8 leader arrow) of the Actuators abut each other to properly position Magazine Catch 7.

FIG. 8 is a rear-right-top isometric view of FIG. 7.

FIG. 9 is a rear-right-top exploded isometric view of the components of the RAMRS.

FIG. 10 is a rear-left-bottom isometric view of FIG. 9.

FIG. 11 is a rear-right-top semi exploded isometric view of the components of the RAMRS with its Reciprocating Cam 13 nestled into its Reciprocating Cam Bracket 11.

FIG. 12 is a rear-left-bottom isometric view of FIG. 11.

FIG. 13 is a rear-right-top semi exploded isometric view of the components of the RAMRS with its Reciprocating Cam 13 nestled into its Reciprocating Cam Bracket 11 and its Left Thumb Actuator Cam Face 9 of Left Thumb Actuator 8 abutted against the Top Lobe 14 of Reciprocating Cam 13.

FIG. 14 is a rear-left-bottom isometric view of FIG. 13.

FIG. 15 is a rear-right-top semi exploded isometric view of the semi assembled components of FIG. 13 in a “Magazine Released State” with the Left Thumb Actuator 8 displaced in a First (−X) Direction.

FIG. 16 is a rear-left-bottom isometric view of FIG. 15.

The crescent moon shaped Reciprocating Cam 13 twists/rotates about its flat face axis due to the interplay between the semicircular Cam Rotation Divot 12 of the Reciprocating Cam Bracket 11 and the Reciprocating Cam's 13 circumference, thus causing its Bottom Lobe 15 to displace in the Opposite (+X) Direction when its Top Lobe 14 is displaced in a First (−X) Direction.

FIG. 17 is a rear view of the fully assembled RAMRS in a Magazine Released State.

FIG. 20 is same as FIG. 7 (RAMRS in a Magazine Secured State) and is shown for comparison purposes with its Reciprocating Cam Bracket 11 aligned vertically with the Reciprocating Cam Bracket 11 of FIG. 17.

When Left Thumb Button 10 of Left Thumb Actuator 8 is pressed (against Biasing Force Means' 16 biasing force) by the left thumb in the First (−X) Direction, interplay between the components displaces Right Thumb Actuator 4 (and thus its integrated Magazine Catch 7) in the Opposite (+X) Direction to effect the system state of FIGS. 21 and 22.

FIG. 18 is a rear-right-top isometric view of FIG. 17.

FIG. 19 is a rear-left-bottom isometric view of FIG. 17.

FIG. 21 is similar to FIG. 3 but with the RAMRS in a Magazine Released State.

FIG. 22 is a detailed view of Section C of FIG. 21. As similarly described for FIG. 4, the Magazine Catch 7 is clear of Catch Divot 3 thus allowing Magazine 2 to be ejected from the Grip Frame.

It is important to note that the Magazine Released State could be effected by the individual pressing of Left Thumb Button 10 or Right Thumb Button 6 or both Thumb Buttons (i.e.—6 and 10) being pressed simultaneously by a thumb and an opposing finger in a force multiplying pinching motion. This feature would allow users of limited hand/finger strength (i.e.—smaller handed or injured) to easily eject the magazine.

It is also important to emphasize that the invention could be configured as an easy “Drop-In” type of system/modification where no alteration (except for the “dropping in” of the parts) of the firearm from original factory configuration is required.

Although the described embodiment utilizes a coil compression spring, alternate embodiments could utilize other (i.e.—torsion, post, leaf, extension, etc,) types of springs. Alternate embodiments could utilize any suitable means (i.e.—adhesives, screws, etc.) to anchor/wedge the Reciprocating Cam Bracket into the Magazine Well. Furthermore, any means to effect a biasing force (i.e.—magnets, etc.) could be utilized.

It is contemplated that the components of the inventive subject matter described herein can be made from suitable materials (e.g.—sheet metal, steel, steel alloys, polymers (plastics), etc.) and processes (e.g.—machining, 3D Printing, Metal Injection Molding, sheet metal folding, etc.) known by those in the art.

Alternative embodiments and/or uses of the methods and devices described above and modifications and equivalents thereof are intended to be included within the scope of the present invention. These embodiments could include any objects which utilize easy assembly/disassembly methods (i.e.—screws, pins, cotter pins, partial turn locking means, magnets, locking washers, locking nuts, etc.).

Although only a semiautomatic handgun is described, the invention could be readily adapted to be utilized in alternate types of firearms (i.e.—(semi and fully automatic) rifles, shotguns, cannons, etc.).

It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
