Self-Aligning Crossbow Interface

Abstract

In some embodiments, a crossbow comprises a bow portion defining a first central vertical axis and a stock portion defining a second central vertical axis. The bow portion comprises an interfacing portion and the stock portion comprises a complimentary interfacing portion. The interfacing portion and the complimentary interfacing portion are arranged to provide self-alignment of the stock portion with the bow portion, such that the first central vertical axis and the second central vertical axis are coaxial.

1 . A crossbow comprising:
 a bow portion defining a first central vertical axis, said bow portion comprising an interfacing portion; and   a stock portion defining a second central vertical axis, said stock portion comprising a complimentary interfacing portion;   wherein said interfacing portion and said complimentary interfacing portion are arranged to provide self-alignment of the stock portion with the bow portion such that the first central vertical axis and the second central vertical axis are coaxial.   
     
     
         2 . The crossbow of  claim 1 , said bow portion defining a first central vertical plane, said stock portion defining a second central vertical plane, wherein said interfacing portion and said complimentary interfacing portion are arranged to provide self-alignment of the stock portion with the bow portion such that the first central vertical plane and the second central vertical plane are coplanar. 
     
     
         3 . The crossbow of  claim 1 , wherein said interfacing portion comprises a first surface and a second surface, each of said first and second surfaces oriented at an angle to said first central vertical axis. 
     
     
         4 . The crossbow of  claim 3 , wherein said first and second surfaces are oriented at equal but opposite angles to said first central vertical axis. 
     
     
         5 . The crossbow of  claim 3 , wherein said complimentary interfacing portion comprises a first complimentary surface and a second complimentary surface, each of said first and second complimentary surfaces oriented at an angle to said second central vertical axis. 
     
     
         6 . The crossbow of  claim 5 , wherein said first and second complimentary surfaces are oriented at equal but opposite angles to said second central vertical axis. 
     
     
         7 . The crossbow of  claim 5 , wherein the first surface abuts the first complimentary surface and the second surface abuts the second complimentary surface. 
     
     
         8 . The crossbow of  claim 1 , comprising a gap located between said interfacing portion and said complimentary interfacing portion. 
     
     
         9 . The crossbow of  claim 9 , comprising a fastener attaching said bow portion to said stock portion, wherein a portion of said fastener is oriented in said gap. 
     
     
         10 . The crossbow of  claim 1 , wherein said bow portion comprises a cavity and a portion of said stock portion is oriented in said cavity. 
     
     
         11 . The crossbow of  claim 10 , wherein said interfacing portion at least partially defines said cavity. 
     
     
         12 . A crossbow comprising:
 a bow portion defining a first central vertical axis, said bow portion comprising a first surface and a second surface disposed at equal but opposite angles to said first central vertical axis; and   a stock portion defining a second central vertical axis, said stock portion comprising a first complimentary surface and a second complimentary surface disposed at equal but opposite angles to said second central vertical axis;   wherein said first and second surfaces and said first and second complimentary surfaces are arranged to provide self-alignment of the stock portion with the bow portion such that the first central vertical axis and the second central vertical axis are coaxial.   
     
     
         13 . The crossbow of  claim 12 , said bow portion defining a first central vertical plane, said stock portion defining a second central vertical plane, wherein said first and second surfaces and said first and second complimentary surfaces are arranged to provide self-alignment of the stock portion with the bow portion such that the first central vertical plane and the second central vertical plane are coplanar. 
     
     
         14 . The crossbow of  claim 13 , wherein said bow portion comprises a nocking point, said nocking point oriented in said second central vertical plane. 
     
     
         15 . The crossbow of  claim 12 , wherein said bow portion comprises a cavity and a portion of said stock portion is oriented in said cavity. 
     
     
         16 . The crossbow of  claim 15 , wherein said first surface and said second surface at least partially define said cavity. 
     
     
         17 . The crossbow of  claim 12 , wherein said first surface abuts said first complimentary surface and said second surface abuts said second complimentary surface. 
     
     
         18 . The crossbow of  claim 12 , comprising a gap between said bow portion and said stock portion, said gap located between said first surface and said second surface. 
     
     
         19 . The crossbow of  claim 18 , comprising a fastener attaching said bow portion to said stock portion, wherein a portion of said fastener is oriented in said gap. 
     
     
         20 . The crossbow of  claim 12 , wherein said first complimentary surface and said second complimentary surface comprise exterior surfaces of said stock portion.
