An adapter which serves as an anchor point for coupling a trailer to a vehicle. The adapter adapted for mating in the socket of the vehicle. The adapter rotatable between a locked and an unlocked position. The adapter including a locking member which, when rotated, moves a ball partially through an aperture, partially extending into the socket thereby locking the adapter within the socket.

An adapter serving as an anchor point for securing a trailer or other object to a vehicle having a socket with a first inside diameter, said socket including a cavity with a second inside diameter, said second inside diameter larger than said first inside diameter, said adapter comprising: a coll
1. An adapter serving as an anchor point for securing a trailer or other object to a vehicle having a socket with a first inside diameter, said socket including a cavity with a second inside diameter, said second inside diameter larger than said first inside diameter, said adapter comprising: a collar formed having a wall including an inner surface and an outer surface, said inner surface defining an inner chamber, said outer surface adapted to be received by said socket within said first inner diameter;an aperture formed in said wall of said collar extending through said wall from said inner surface of said wall to said outer surface of said wall, said aperture shaped as a truncated cone, having a larger diameter at said inner surface of said wall and a smaller diameter at said outer surface of said wall;an S-cam carried within said inner chamber of said collar, said S-cam being rotatable about a central axis with respect to said inner chamber and including a deep recess and a shallow recess within an outer surface of said S-cam; and a ball retained in said aperture and moveable between an retracted position and an extended position wherein said ball protrudes beyond said outer surface of said wall, said ball movable along said outer surface of said S-cam between an unlocked position corresponding to said ball being located in said deep recess and a locked position corresponding to said ball being in said shallow recess, whereby said ball protrudes into said cavity when said ball is in said shallow recess and said collar is in said socket. 2. The adapter of claim 1, a shaft fixed from rotation with respect to said S-cam, said shaft rotatable between said locked position and said unlocked position, said locked position being where said ball is located in said extended position, said unlocked position being where said ball is in said refracted position. 3. The adapter of claim 2, and a locking member adapted to selectively fix said S-cam from rotation with respect to said collar. 4. The adapter of claim 3, said collar having castellations, said locking member being an arm that is fixed to said shaft and rotatable therewith, said arm engaging with said castellation when said S-cam is in said locked position. 5. The adapter of claim 3, and a second aperture formed in said wall of said collar, said locking member adapted to extend through said second aperture and engage said shaft to selectively fix said shaft from rotation when said shaft is in its locked position. 6. The adapter of claim 2, wherein said S-cam is formed from a series of stacked plates. 7. The adapter of claim 6, said S-cam having and a low friction surface, said surface limiting the vertical movement of said ball. 8. The adapter of claim 7, wherein said S-cam is formed from a series of stacked plates. 9. An adapter for selectively fixing to a socket, said socket having a first inside surface, and a second inside surface defining a cavity, said second inside surface extending outwardly of than said first inside surface, said adapter comprising: a collar having a wall including an inner surface and an outer surface, said inner surface defining an inner chamber said outer surface smaller than first inside surface;a cam movable with respect to said collar between a locked and an unlocked position, said cam having a shallow recess and a deep recess on an outer surface of said cam, said cam carried within said inner chamber;a shaft extending from said cam and movable therewith;an aperture formed in said wall of said collar extending through said wall from said inner surface to said outer surface, said aperture having a smaller diameter near said outer surface and a larger diameter near said inner surface;a ball retained inside said aperture and having a diameter, said diameter of said ball being smaller than said larger diameter of said aperture and larger than said smaller diameter, said ball movable along said cam between said shallow recess and said deep recess, said locked position defined by said ball adjacent to said shallow recess and extending into said cavity, and said cam, said, said unlocked position defined by said ball adjacent to said deep recess. 10. The adapter of claim 9, and a locking member adapted to restrict movement of said cam when said cam is in said locked position. 11. The adapter of claim 10, said collar having a castellation, said locking member engaging with said castellation when said cam is in said locked position. 12. The adapter of claim 11, wherein said cam is formed from a series of stacked plates. 13. The adapter of claim 10, and a second aperture formed in said wall of said collar, said locking member adapted to extend through said second aperture and engage said shaft when said cam is in said locked position. 14. The adapter of claim 9, said cam having a low friction surface. 15. The adapter of claim 9, wherein said locking member cam is formed from a series of stacked plates. 16. An adapter serving as an anchor point for securing a trailer or other object to a vehicle, said adapter comprising: a socket affixed to said vehicle and having an inside surface, said inside surface having a depression to define a cavity;a collar having an exterior surface and an interior surface, said interior surface defining an inner chamber, a portion of said exterior surface adapted to be received by said socket;an aperture in said surface of said collar, said aperture shaped as a truncated cone, said cone having a smaller diameter intersecting said exterior surface and a larger diameter intersecting said interior surface;a locking member carried within said inner chamber and movable between a locked and an unlocked position, said locking member having a recess; anda ball disposed between said recess and said exterior surface when said locking member is in said unlocked position, said locking member rotatable to said locked position in which said locking member moves said ball outwardly of said exterior surface so that said ball may be received in said cavity for locking engagement with socket. 17. The adapter of claim 16, said locked position defined by said ball extending into said depression when said locking member is in said locked position. 18. The adapter of claim 16, said locking member capable of being fixed with respect to said collar when said locking member is in said locked position. 19. The adapter of claim 16, and an extension member carried within said collar, said extension member joined to said locking member, a pin is optionally insertable through said collar and said extension member, whereby said pin prevents movement of said locking member between said locked position and said unlocked position.
