DESCRIPTION
This disclosure is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws “to promote the progress of science and useful arts” (Article 1, Section 8).
Firearm assemblies and methods are provided with reference to FIGS. 1-8. Referring first to FIG. 1, a firearm frame assembly 10 is shown in a perspective view. As an example, frame 10 is configured to engage a slide action having a barrel portion therebetween. A portion of frame 10 can be configured to receive a magazine within magazine chamber 12, and magazine chamber 12 is configured within grip portion 14 which can be attached to frame 10. In accordance with example implementations, frame 10 can be that of a semiautomatic pistol. Frame 10 can define a receiver configured to engage the slide with the receiver extending from grip 14.
According to example implementations, assembly 10 can include cover 16 engaging grip 14 to define an enclosure recessed within grip 14. Cover 16 can have a switch integrated therein, and grip 14 can be configured to couple with cover 16 which is removeably-fixedly engaged with the grip portion.
According to example implementations, cover 16 can enclose a power source that can be electrically coupled through frame 10 to engage accessories that may be coupled to frame 10. According to example implementations, the power source can be coupled via an electrical conduit 19 through opening 18 and then through opening 20 to engage accessories on the exterior of frame 10. Conduit 19 can extend between a power coupling assembly and the power source. Conduit 19 can exit frame 10 and extend along the exterior of frame 10 toward a forward portion of a trigger guard to engage the coupling assembly.
According to an embodiment, the power source may be directly wired to accessories through these openings. According to other embodiments, the power source can be wired to an electrical coupling device proximate and/or extending from opening 20. Accessories may be configured to engage this coupling device when mounted to frame 10. Accessories that may be mounted to the exterior of frame 10 include laser targeting systems and/or lighting systems, for example.
While opening 20 is shown along one side of frame 10, additional openings or other openings can be provided along the opposing side of frame 10. These additional openings can be provided to accommodate shooters that prefer the accessories mounted on specific side or portion of frame 10. Opening 20 can receive a gasket configured to form an airtight seal around conduit 19.
Referring to FIG. 2, a cross-section of frame 10 is shown. As shown in this cross-section, opening 20 is configured to receive wire couplings from power source 15 which is recessed within grip 14. The recess of grip 14 can extend along a distal edge of grip 14 from a butt of grip 14. Cover 16 can define at least a portion of the butt of grip 14 when enclosing power source 15.
Source 15 can be a battery or set of batteries. Example batteries include but are not limited to button cell batteries. Configured as a slide action firearm, the receiver can extend from grip 14. Frame 10 can define trigger guard 26 extending between the receiver and grip 14. Grip 14 can include sides 13 and distal and proximal edges 17 (FIGS. 1 and 4). Sides 13 and edges 17 can extend from a butt 21 and can be associated with guard 26. More particularly, proximal edge 17 can be associated with guard 26, and power source 15 can be recessed within distal edge 17. In a first position, cover 16 can be fully engaged with grip 14 and define an enclosure for source 15. In this first position, cover 16 can retain batteries within grip 14. In a second position, cover 16 can at least partially and/or fully expose the recess of grip 14. According to specific implementations, in the second position, cover 16 can expose one battery while retaining the other. According to other implementations, cover 16 can expose both batteries with still remaining engaged with grip 14.
When engaged with grip 14, cover 16 can complete a continuous edge 17. Such a continuous edge can be consistent with a grip or grips having no power source. Example grip types that can include power source 15 and cover 16 are 1911 style grips.
Referring to FIG. 3, a side view of assembly 10 is shown according to an embodiment. According to an example implementation, cover 16 can include switch portion 30. Switch portion 30 can be a single position on/off switch that can take the form of a flexible material encased push button. In one position, switch portion 30 can allow power to be provided to an accessory. In another position, switch portion 30 can prohibit power from being provided from source 15 to an accessory.
Frame 10 can include a power coupling assembly 24 positioned along the frame and/or mounted along frame 10. Coupling assembly 24 can be in electronic communication with source 15, for example. Assembly 24 can be configured as a portion of a connection, such as male or female receptacle. In accordance with example implementations, plug and socket, blade, and/or ring and spade connectors may be utilized. Power coupling assembly 24 can be positioned along the receiver of frame 10. Power coupling assembly 24 may be associated with an accessory mounting assembly 23. Power coupling assembly 24 can be positioned on a portion of ring guard 26 distal of grip 14. Assembly 24 can be located between guard 26 and the receiver.
Accessory mounting assembly 23 can be configured to removeably-fixedly engage an accessory 22. Mounting assembly 23 can be proximate power coupling assembly 24. The proximity of theses assemblies can facilitate both the power coupling and mounting of accessories (22) to frame 10. Assembly 23 can be configured to mate with accessory 22; such assemblies include but are not limited to clips, such as vice clips.
Referring to FIG. 4, and in accord with an example implementation, component 16 can be configured to receive rails 42 of grip portion 14. These rails 42 can be received by flange and post portions 44 of component 16. Rails and/or flange and post portions can be configured to allow cover 16 to slidably engage grip 14.
In accordance with additional implementations, conduit 19 can extend to more than one accessory. Conduit 19 can be severed to provide power to these accessories and/or conduit 19 can extend between the accessories in series. In accordance with additional implementations, frame 10 can be coupled to both a laser sight and a light for example.
Referring to FIGS. 5-8, more detailed views of component 16 are shown. According to example implementations and referring to FIG. 8, component 16 can include recesses 82 configured to receive power sources such as batteries. Component 16 can also include hook and post portion 52 configured to resiliently engage an opening of assembly 10. Portion 52 can be configured to hold component 16 in a fixed position along grip portion 14 to provide a seamless engagement of component 16 as part of grip portion 14. According to example implementations, component 16 can be utilized to provide power to accessories within or along assembly 10 while at the same time providing a complete grip without obstructions or additions.
In compliance with the statute, embodiments of the invention have been described in language more or less specific as to structural and methodical features. It is to be understood, however, that the entire invention is not limited to the specific features and/or embodiments shown and/or described, since the disclosed embodiments comprise forms of putting the invention into effect. The invention is, therefore, claimed in any of its forms or modifications within the proper scope of the appended claims appropriately interpreted in accordance with the doctrine of equivalents.
