BACKGROUND

Armaments include rifles and other small weapons, i.e., weapons that are typically hand carried, e.g., those of the AR-15, M-16 and M-5 style; as well as handguns, e.g., Baretta® 92, Colt® 1911 and Glock® 17 styles; as well as other projectile propelling weapons, e.g., those which may be currently in use or development by US and Global armed forces, police agencies and sportsmen. Frequently these armaments are equipped with mounted accessories. Sometimes these armaments are equipped with numerous mounted accessories. In addition, these armaments may be equipped with numerous rail mounted accessories, e.g., combat optics, tactical optics, laser designators, laser sights, range finders, and flashlights.
Since these accessories are of conventional design and originate from numerous commercial sources, they frequently have a variety of power requirements, battery types, heat generation levels, and operating specifications. The result is an assortment of accessories and components which, upon integration with an armament, may create a heavy and/or bulky armament system.
Patent application Ser. No. 13/999,054 filed Jan. 8, 2014, the contents of which are incorporated by reference herein as if set forth in its' entirety, generically discloses apparatus having management of electrical power capacity regions and management of thermal capacity regions.
The publication; Military Standard: Dimensioning of Accessory Mounting Rail for Small Arms Weapons, AMSC, 3 Feb. 1995; establishes standard methods of dimensioning accessory mounting rails for small arms weapon systems. It also establishes uniform accessory mounting rails and requirements that are interchangeable among the different units of the U.S. Defense Department.
Thus, it is clear that armament system components and the materials with which they are made must be reconsidered in an effort to meet the still known unmet needs as well as those that will emerge well into the future.

The present invention may be an integrated, multi-component, multifunctional structural system for a firearm or other trajectory propelling apparatus wherein at least one first member comprising an electrically conductive composite having controlled thermal properties is combined, for example, by adapted fabrication process with a second structural member having controlled thermal and electrical properties to form a functional assembly for an armament of any size. Examples of adapted fabrication processes include, but are not limited to, pultrusion, extrusion, lay-up, insert molding, cast molding, injection molding, blow molding, resin transfer molding, lamination, press- or friction-fit assembly, and/or combinations thereof. The first member is preferably electrically conductive throughout or upon or within selected regions and may consist of an intrinsically conductive polymer or a host polymer containing electrically conductive fibers, powders, flakes, shards, or other electrically conducting fillers or a conductive composite or filler having an adapted metal layer applied thereto. In the case where continuous, conductive fibers or discontinuous length fibers of any size are preferred, they may be assembled into convenient to handle and process intermediate forms, for example, in the form of tows, yarns, films, ribbons, foils, sheets, cloths, 2-dimensional and 3-dimensional fabrics, or felts by any adapted method to produce a woven or non-woven or knitted intermediate which may be pre-impregnated with an adapted binder to form an intermediate referred to as a prepreg. Combinations of the foregoing are also options for forming a first member. Metallic fibers or fine wires may be integrated into an intermediate film, foil, sheet, fabric, or felt along with other non-metallic polymers or fibers. Further, metals may be applied in any adapted thickness or location upon or within a filler or other polymeric substrate to enhance the electrical or thermal conductivity by various methods such as electroless plating, electro plating, electro spraying, vapor deposition, vacuum deposition, ion intercalation; dip-, spray-, or other-coating method of a base metal or metal containing fluid, emulsion, ink, paint, or paste; or combinations thereof. In some applications, a Nobel or corrosion resistant metal overplating of a base metal intermediate layer on a substrate may be preferred. The first member may be adapted for conducting power and/or a signal between one location and a second. Within or upon the first member may be regions that provide electric interconnection sites for an accessory, a power source, a system or component specific controller, a user-interface apparatus, or other element.
In addition, the first member may have controlled thermal properties and would therefore be thermally conductive, semiconductive or insulating; depending upon the requirements of the specific local application. In preferred embodiments the first member serves to provide the ability to move, remove, and/or store heat which may be generated by operation of an advanced armament system or by operation of the electric circuit generated by a first member and thereby serves to manage local temperatures within the integrated structure to optimize operational functions and component life.
When in combination with a second structural member that is electrically insulative and having controlled thermal properties, the integrated member serves in general as a major portion of an advanced armament system. For many advanced armament systems, a second member is larger in area or volume in comparison to the first and serves as a primary component of a stock, a housing, a grip, shroud, a frame, or body member. More than one first and second member may be combined to form a large structure and may contain one or more accessibly embedded contact surface regions. Moreover, the second structural member may be electrically insulative but thermally conductive which permits enhanced external cooling of portions of the armament or of the entire armament. Optionally, portions of the external surface of the advanced armament system may have macroscopic surface components, such as fins, louvers, gratings, ports, holes, slots, struts, threaded, clamp-type fastening sites and the like, or microscopic surface components, e.g., a micro-roughness, mixed surface composition, colorants, or modified surface energy which may assist in heat dissipation, aesthetics, as well as handling ability and maintenance of the armament system. Also, optionally, the structure may comprise one or more regions having accessibly embedded contact surface regions that provide for electric or thermal interconnection that are self-sealing, self-repairing, self-healing, fluid tight, environmentally stable or in combination. Also, optionally, the structure may comprise one or more regions having embedded or partially embedded optically transparent or transmissive members, i.e., fiber optic elements made from glass, polymer, quartz, or any other material having suitable optical properties.
The first member may be integrated within or upon the second member to form an advanced composite member and serves to conduct signal or power adapted to activate, monitor, control, or energize an accessory that is appropriately mounted onto the advanced composite member which is configured to provide points or regions of electric interconnectivity amongst the conducting inner member and one or more circuit elements such as a battery, a switch, a user-interface, electronic controller, or other accessory. Any region at the ends of, or along any surface of, or upon the conductive first member, may be configured in the form of an accessibly embedded contact surface which serves to make electrical contact between the conductor and circuit element.
Any appropriate approach may be used to produce the desired surface contact wherein the contact may be embedded and thereby not be initially fully exposed or operational. These approaches include, but not limited to, waterjet cutting, waterjet sculpturing, laser cutting, laser forming, thermoforming, solvent cleaning, chemical etching, mechanical-milling, mechanical-piercing, mechanical-abrading, mechanical-turning, mechanical-polishing, and combinations thereof. In general, establishment of an effective electrical contact involves physical contact between two conductive domains, pads, regions, or surfaces at an interface wherein sufficient mechanical force is exerted, for example compressively and/or in shear, to create and maintain sufficient contact pressure between the mating contacts.
The pressure across the contact interface creates an electromechanical connection that serves to achieve a low contact resistance. This provides a path for current flow from one contact member to another. The contact pressure across the contact region also serves to assist in sealing out, eliminating, minimizing dirt, dust, snow, and moisture from contaminating the contact.
Advanced conductive composites are comprised of a conductive filled polymer system which typically have a polymer rich exterior surface layer that is microscopically different in composition that the rest of the composite materials may be used. However, the surface layer is generally too resistive to provide for low contact resistances at specific contact pressures. In this case, as in the case of accessibly embedded contact surfaces in general, the surface may require alteration, displacement, or removal of at least some of the surface layer in the regions where electric contact will be made in order to alter the surface composition in favor of a higher conductive filler concentration and a resulting lower contact resistance region.
In addition to the earlier mentioned surface preparation methods, other methods may be used to alter the surface resistance at the desired points of contact. These include, but are not limited to, chemical washing, etching, or erosion of the polymer phase at the surface, mechanical sanding or polishing, interpenetrating the surface with an adapted conductive penetrant, overcoating with a suitably conducting layer, e.g., a conductive paint or lubricant, a metal overplating layer, or combinations thereof. In addition, an adaptive sealant or seal may be applied to the contact regions to provide for a fluid tight and environmentally robust contact zone. The seal may be of the smart, self-repairing, or self-sealing type. Contacts made in accordance with the present invention provide a high degree of corrosion resistance, low contact resistance at minimal contact pressure, excellent vibration and temperature tolerance, and as a consequence are generally highly reliable.
Likewise, contact(s) made between two or more thermally conducting members where heat movement across the interconnect is desirable may be configured in a similar fashion such that guidelines for establishing reliable electrical interconnects also apply to establishing thermal interconnects.
The electrical interconnect, when formed by two contacts, may be permanent or temporary. In the case where a permanent interconnect is desired conductive adhesives, chemical bonding, thermal welding, mechanical impact coining, soldering, insert molding, or combinations thereof may be used to join the contact surfaces. In the case where a circuit element is affixed at a contact interconnect in a temporary or removable condition, the contact pressure may be established by employing flexure in the composite member by configuring some, or the entire element similar to a leaf or coil spring. The contact regions may be configured into blade or pin and socket pairings where displacement, for example, in a semi-rigid socket member by a slightly oversize blade creates the desired contact properties. Alternatively, a non-permanent conducting adhesive, conductive grease or similar material may be used to temporarily or removeably secure the contacting elements. In addition to the contact members themselves, other means may be used to provide for permanent or temporary contact interconnects. These include but are not limited to mechanical fasteners, e.g., screws, bolts, nuts, rivets, clamps, and the like.
Although this description pertains largely to the components, performance, and preparation of the electric contact region, any desired thermal interconnect may be designed and constructed in similar fashion wherein effective heat flow is managed within the member and across its interconnect with another element.
Thus, the integration of the first and second members into a single multi-component member having the above-described contact interconnects provides a means to activate, interrogate (sense), or energize a suitably mounted accessory, e.g., a flashlight or other light source, an electronic sight, a range determining laser component, a signaling component, a switching component, a secondary non-lethal propulsion component, e.g., a Taser, or a secondary lethal propulsion component, e.g., a grenade or tear gas launcher.
A non-limiting example of an application of the invention herein is use of the invention described herein as a composite firearm stock, grip member, housing, mounting, shroud, rail, frame, accessory base, and/or barrel for modern armament. Since the appropriately configured thermal and electrical pathways may be imbedded within the composite member, many individual components may be integrated into a single unit thereby reducing the parts count and avoiding certain failure modes. Also, the first member may serve, either in part or fully, as a mounting or housing for a portion of the component or accessory enabling the user to interface with the firearm or accessory in ways that are safe and reliable.
There are commercially available butt stocks, rails, grips, and similar armament related products. The invention herein allows for designs which take advantage of available space within and around the commercially available member. In such an embodiment of the invention herein the same principles as described above are equally applicable to other portions of an advanced armament system and any such variation would be within modifications that do not part from the scope and spirit of the present invention as claimed herein.
The invention may be better understood by reference to the drawings wherein like figure numbers are used to illustrate like components contained in the drawings. FIG. 1 illustrates an AR 15 type rifle that is typical of a small armament (1) in contemporary use. A prior art accessory mounting rail (P) is shown affixed at a topmost center position upon the receiver portion (10) of the armament (1). One or more accessory rails (P) may be affixed at various other locations on the armament (1) to enable mechanical attachment of one or more user selected accessories (not shown). FIG. 2 provides additional details of a prior art accessory mounting rail (P) comprised of ribs (R) and spaces (S). The ribs (R) are generally uniformly distributed along the topmost surface (30) of the accessory mounting rail (P) thereby providing a relatively standardized configuration for mechanical attachment of functional accessories (not shown).
FIG. 3 shows a particular embodiment of the present invention comprising an accessory mounting power rail apparatus (300) which includes a pair of electro conductive power buss inserts (310) (see also FIGS. 4 and 5) that span the length of the accessory mounting power rail apparatus (300). In this embodiment of the invention herein, the accessory mounting power rail apparatus (300) comprises various regions that can be represented by an upper surface (320) having an interdigited array of grooves (380) and ridges (390) below which the earlier mentioned pair of electro conductive power buss inserts (310) are located. The electro conductive power buss inserts (310) are preferably made from a suitable electro conductive composite. This embodiment of the accessory mounting power rail apparatus (300) reflects the mechanical features that are typical of a military standard accessory mounting rail apparatus (P) as shown in FIG. 2, as well as a provision to conduct electrical current to various locations within and along the accessory mounting power rail apparatus (300), i.e., the electro conductive power buss inserts (310). The electro conductive power buss inserts (310) serve to conduct electric current along the length of the accessory mounting power rail apparatus (300) and are contained within the composite second member (330) comprised of a thermally conductive, electrically insulating polymer formed to provide the illustrated features.
Other features, such as side grooves (370) may be molded, machined, or otherwise formed into the accessory power rail apparatus (300) to provide additional locating and mounting options for a variety of accessories (not shown).
The accessory mounting power rail apparatus (300) of FIG. 3 may be fabricated by any adapted process, processes, and process steps; including, for example, insert molding of pultruded rod-shaped preforms via the following process steps: 1) pultrusion of a rod shaped pre-form first member(s) comprising electro conductive fibers secured in a host polymer where the first member(s) are rigid and are circular (310) or angular electrically conductive rods, i.e., electro conductive power buss inserts (310) 2) insertion of the electro conductive power buss inserts (310) into ports within a suitably designed and prepared injection molding die, 3) injection molding of an adapted thermally conductive polymer under heat and pressure to fill the mold and, at least partially, encapsulate the pre-form first member(s) (310), 4) cooling the composite filled die comprising the electro conductive power buss inserts (310) secured within a thermally and electrically insulative second member (330) to sufficiently low temperature(s) to solidify the assembly (300), and then, 5) ejecting the accessory mounting power rail apparatus (300) from the die resulting in the accessory power rail apparatus (300) of FIG. 3.
Referring now to FIG. 4, illustrated is one embodiment of internal features of the accessory mounting power rail apparatus (300). The pair of electro conductive power buss inserts (310) shown in FIG. 4 are embedded in a second advanced composite material (470) and serve as interconnections at specific regions (412) in and on the accessory mounting power rail apparatus (300). In specific, it illustrates one (415) of a pair of two first members (310) that run inside of the upper (450) and lower (460) member of the accessory mounting power rail apparatus (300). The second (not shown) of first member (415) can be seen in FIG. 5. The first members (310, 415) are comprised of electrically conductive composite materials having predetermined and controlled thermal properties. The first members (310, 415) are preferably molded as pre-forms and then located in an electrically insulated second member (450) and combined with a third base member formed of the second advanced composite material (470) to form the accessory mounting power rail apparatus (300). The first members (310, 415) serve to conduct current from and to various locations at the ends (417) and (416) and to specific regions (412) along the length of the accessory mounting power rail apparatus (300) where connection to an accessory (not shown) may be made. After assembly resulting in the accessory mounting power rail apparatus (300), the two first members (310, 415) are nearly fully embedded in the advanced composite of the second member (450, 470) and encased at the bottom by the third base member (470). Within the base member (460) and within the top member (450) are shown one type of additional feature such as a series of thru holes (480) that permit mechanical mounting of the rail assembly (300) to the armament (1) of FIG. 1. Thus, FIG. 4 shows additional details of the accessory mounting power rail apparatus's (300) internal structure. One of a pair of electro conductive advanced composite members (310) are embedded in a second advanced composite material (450, 470) that serve as interconnections at various locations (412) in and on the power rail mounting apparatus (300) and are visible in FIG. 3 as two dots (310) at the leftmost region (417) of the accessory mounting power rail apparatus (300). While in practice and as above mentioned, the first member (414) and second member (450) may be formed into a single assembly, i.e., the upper portion of the accessory mounting power rail apparatus (300) by, for example, insert injection or transfer molding. Thus, the upper member (450) containing the conductive first members (415, 412) and lower member (470) containing the conductive first members (310) may be formed individually and then joined together by any adapted means, e.g., adhesive bonding, thermal welding, sonic welding, mechanical fastening, and combinations thereof.
Provision is made for the first members (310, 415) to span the length of the accessory mounting power rail apparatus (300) from one end (417) to the other (416). Along the span of the accessory mounting power rail apparatus (300) further provisions (412) are incorporated in the upper member (450) for linking appendages (412) to electro-mechanically interconnect between the electro conductive power buss inserts (310, 415) and a plurality of locations (412) forming a network where a power requiring accessory (not shown) is capable of being mounted and connected to the electro conductive power buss network (310, 412, 415). Electrical current is provided to the accessory (not shown) by interconnecting contact regions (not shown) on the accessory to appropriate mating contact points or regions (412) on the accessory mounting power rail (300). The lower member (470) serves to complete the assembly and enables mounting of the rail apparatus onto other apparati, such as to the receiver member of a small arm (1) as illustrated in FIG. 1.
FIG. 5 is a transparent view of the embodiment of the present invention shown in FIGS. 3 and 4 providing additional details of the accessory mounting power rail apparatus (300) illustrating the inset assembly of first members (310, 412, 415) integrated into the upper (450) and lower (470) members of FIG. 4 thus illustrating the electro conductive power buss inserts (310) with interconnecting conductive appendages (512) to comprise the electro conductive power buss network (310, 412, 415) as an element of the integrated assembly of first mechanically strong and rigid electro conductive power buss members (310, 415) with interconnecting linkages (412) configured within the second, mechanically strong, rigid, predetermined thermally conductive members (330, 450, 470) as shown in FIGS. 3 and 4. Examples of adapted fabrication processes which may be used to form the accessory mounting power rail apparatus include, but are not limited to, pultrusion, extrusion, lay-up, insert molding, cast molding, injection molding, blow molding, resin transfer molding, lamination, press- or friction-fit assembly, and/or combinations thereof. Examples of suitably adapted materials include, for example, conductive composite plastics, preformed metals, foils, intrinsically conductive polymers or a host polymers containing electrically conductive fibers, powders, flakes, shards, or other electrically conducting fillers or conductive composites or fillers having an adapted metal layer applied thereto. In the case where continuous conductive fibers or discontinuous length fibers of any size are preferred, they may be assembled into convenient to handle and process intermediate forms, for example, in the form of tows, yarns, films, ribbons, foils, sheets, cloths, 2-dimensional and 3-dimensional fabrics, or felts by any adapted method to produce a woven or non-woven or knitted intermediate which may be pre-impregnated with an adapted binder to form an intermediate referred to as a prepreg. Combinations of the foregoing are also options.
Metallic fibers or fine wires may be integrated into an intermediate film, foil, sheet, fabric, or felt along with other non-metallic polymers or fibers. Further, metals may be applied in any adapted thickness or location upon or within a filler or other polymeric substrate to enhance the electrical or thermal conductivity by various methods such as electroless plating, electro plating, electro-spraying, vapor deposition, vacuum deposition, ion intercalation, dip-, spray-, or other-coating method of a base metal or metal containing fluid, emulsion, ink, paint, or paste, or combinations thereof. In some applications, a Nobel or corrosion resistant metal overplating of a base metal intermediate layer on a substrate may be preferred. The first member is adapted for conducting power and/or a signal between one location and a second. Within or upon the first member are regions that provide electric interconnection sites for an accessory, a power source, a system or component specific controller, a user-interface apparatus, or other element.
The interconnective conducting appendages (512) may be co-formed with the main electro conductive buss members (310, 415) by any suitable adapted process including, for example, machine forming, compression forming of pin or rod shaped members into holes, adhesive bonding of appendages to the base member, and the like. Provisions may be made to enable the ends of the electro conductive power buss members (310, 415) and/or the interconnective conductive appendages (512) to be exposed at the end locations (416, 417) and along the rail surfaces (320) either during formation process of the accessory mounting power rail (300) or subsequent to assembly fabrication of the accessory mounting power rail (300). Any suitable adapted means may be used to prepare the exposed contact surfaces at all, or optionally, at only designated locations. In the case where an accessory (not shown) is to be mounted permanently, for example, onto the accessory mounting power rail (300) apparatus, it may be desired to only expose contact regions where the accessory will be interconnected thus preventing unwanted electrical shorting between unused contact points.
