  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • [0018]
    Referring to FIGS. 1A, 1B, 2A, 2B & 3, there is shown firearm 10. Firearm 10 may include barrel assembly 12, to which muzzle brake 14 may be attached. Barrel assembly 12 may be coupled to receiver assembly 16. While this particular example, receiver assembly 16 is shown to be a bolt action receiver assembly (e.g., a traditional bolt action or a straight-pull bolt action), other configurations are possible and are considered to be within the scope of this disclosure and the related claims. For example, receiver assembly 16 may be a pump action receiver assembly (such as used in a shotgun, not shown) or a semi-automatic/fully automatic receiver assembly (such as used in an assault weapon/battle rifle, not shown). Firearm 10 may include folding stock assembly 18, which may include butt stock portion 20, receiver interface portion 22, and bidirectional hinge assembly 24.
  • [0019]
    Butt stock portion 20 of folding stock assembly 18 may be configured to allow for a length of pull adjustment. For example, butt stock portion 20 may include shoulder interface 26 which may be longitudinally displaceable (in the direction of arrow 28) via e.g. one or more rods assemblies 30, 32 that may be slidably attached to main body 34 of butt stock portion 20. For example, through the use of shoulder interface 26, the distance between the shoulder of the user (not shown) of firearm 10 and trigger assembly 36 of firearm 10 may be adjusted, thus allowing for more comfortable and/or efficient use of firearm 10.
  • [0020]
    Further, butt stock portion 20 of folding stock assembly 18 may be configured to allow for a cheek weld adjustment. For example, butt stock portion 20 may include cheek interface 38 (shown in phantom), which may be latitudinally displaceable (in the direction of arrow 40), thus allowing the user (not shown) of firearm 10 to latitudinally position their eye behind a sighting device (such a holographic site, a scope, or iron sights, not shown).
  • [0021]
    Depending upon the manner in which butt stock portion 20 is constructed, butt stock portion 20 may be constructed of an organic material (e.g. wood) or may be constructed of a synthetic material (e.g. fiberglass-reinforced plastic)
  • [0022]
    As discussed above, firearm 10 may include receiver assembly 16 which may be coupled to barrel assembly 12. Accordingly, receiver interface portion 22 may be configured to couple receiver assembly 16 to folding stock assembly 18. For example, receiver interface portion 22 may be configured to be rigidly affixed to receiver assembly 16 via e.g. one or more threaded fasteners (not shown).
  • [0023]
    Bidirectional hinge assembly 24 may be configured to allow butt stock portion 20 to bidirectionally pivot with respect to receiver interface portion 22. Specifically, FIG. 1A illustrates a right-side view of firearm 10 with butt stock portion 20 positioned in a non-folded position, wherein FIG. 1B illustrates the same right-side view of firearm 10 with butt stock portion 20 positioned in a first folded position (e.g. butt stock portion 20 positioned on the right side of firearm 10). Further, FIG. 2A illustrates a left-side view of firearm 10 with butt stock portion 20 positioned in a non-folded position, wherein FIG. 2B illustrates the same left-side view of firearm 10 with butt stock portion 20 positioned in a second folded position (e.g. butt stock portion 20 positioned on the left side of firearm 10).
  • [0024]
    Referring also to FIGS. 4A, 4B, 4C, bidirectional hinge assembly 24 may include first hinge assembly 50 and first latch assembly 52 configured to releasably lock first hinge assembly 50 in a non-folded position. Bidirectional hinge assembly 24 may further include second hinge assembly 54 and second latch assembly 56 configured to releasably lock second hinge assembly 54 in the non-folded position. Bidirectional hinge assembly 24 may also include coupler assembly 58 configured to pivotally couple first hinge assembly 50 and second hinge assembly 54.
  • [0025]
    FIGS. 4A, 4B, 4C illustrate a top view of the operation of bidirectional hinge assembly 24 when folding butt stock portion 20 of folding stock assembly 18 into the first folded position (e.g. butt stock portion 20 positioned on the right side of firearm 10). In order to effectuate the folding of butt stock portion 20 into this first folded position, the user of firearm 10 may depress first latch assembly 52 (in the direction of arrow 60), resulting in first latch assembly 52 disengaging from first recess 62. Depending upon the manner in which bidirectional hinge assembly 24 is configured, first recess 62 may be included within coupler assembly 58 or first bracket 64 of bidirectional hinge assembly 24. Once the user of firearm 10 depresses first latch assembly 52 (in the direction of arrow 60), the user of firearm 10 may rotate (in the direction of arrow 68) butt stock portion 20 of folding stock assembly 18 into the first folded position (e.g. butt stock portion 20 positioned on the right side of firearm 10).
  • [0026]
    Referring again to FIG. 1A, folding stock assembly 18 may include first catch assembly 66, which may be configured to releasably hold butt stock portion 20 in the first folded position (e.g. butt stock portion 20 positioned on the right side of firearm 10). First catch assembly 66 may be configured to releasably engage first mating catch 68 positioned on the right-side of firearm 10.
  • [0027]
    Referring also to FIGS. 5A, 5B, 5C, a top view of bidirectional hinge assembly 24 is shown to illustrate the operation of folding butt stock portion 20 of folding stock assembly 18 into the second folded position (e.g. butt stock portion 20 positioned on the left side of firearm 10). In order to effectuate the folding of butt stock portion 20 into this second folded position, the user of firearm 10 may depress second latch assembly 100 (in the direction of arrow 102), resulting in second latch assembly 100 disengaging from second recess 104. Depending upon the manner in which bidirectional hinge assembly 24 is configured, second recess 104 may be included within coupler assembly 58 or second bracket 106 of bidirectional hinge assembly 24. Once the user of firearm 10 depresses second latch assembly 100 (in the direction of arrow 102), the user of firearm 10 may rotate (in the direction of arrow 108) butt stock portion 20 of folding stock assembly 18 into the second folded position (e.g. butt stock portion 20 positioned on the left side of firearm 10).
  • [0028]
    Referring again to FIG. 2A, folding stock assembly 18 may include second catch assembly 110, which may be configured to releasably hold butt stock portion 20 in the second folded position (e.g. butt stock portion 20 positioned on the left side of firearm 10). Second catch assembly 110 may be configured to releasably engage second mating catch 112 positioned on the left-side of firearm 10.
  • [0029]
    Referring also to FIGS. 6A & 6B, butt stock portion 20 of folding stock assembly 18 may include bolt retention receptacle 150 configured to releasably receive bolt handle 152 of bolt assembly 154 when butt stock portion 20 is positioned in the first folded position (e.g. butt stock portion 20 positioned on the left side of firearm 10). Bolt retention receptacle 150 may be configured to impede rearward motion (in the direction of arrow 156) of bolt assembly 154 when bolt handle 152 is positioned within bolt retention receptacle 150. For example, bolt retention receptacle 150 may be configured to fit snuggly or fit loosely around bolt handle 152 whenever (and as discussed above) butt stock portion 20 is held in the first folded position (e.g. butt stock portion 20 positioned on the right side of firearm 10) via first catch assembly 66 in conjunction with first mating catch 68. Accordingly and through the use of bolt retention receptacle 150, the inadvertent detachment of bolt assembly 154 from firearm 10 may be avoided.
  • [0030]
    While bolt retention receptacle 150 is described above as capturing bolt handle 152 whenever butt stock portion 20 is positioned on the right side of firearm 10, this is for illustrative purposes only and is not intended to be a limitation of this disclosure. For example, if firearm 10 is configured such that bolt handle 152 is positioned on the left side of firearm 10, bolt retention receptacle 150 may be configured to capture bolt handle 152 whenever butt stock portion 20 is positioned on the left side of firearm 10.
  • [0031]
    Having thus described the disclosure of the present application in detail and by reference to embodiments thereof, it will be apparent that modifications and variations are possible without departing from the scope of the disclosure defined in the appended claims.
