An improved hitch mechanism is provided that includes an elongated shaft for connecting with a ramp or trailer, and a mating member for connecting with a tow ball of a tow hitch. The mating member includes a chamber disposed therein for housing the tow ball in a first position and in a second position. When the tow ball is in the first position in the chamber, the mating member and the elongated shaft are rigid relative to the tow hitch. When the tow ball is in the second position in the chamber, the mating member and the elongated shaft are non-rigid relative to the tow hitch.

An apparatus comprising: an elongated shaft for connecting with a ramp or trailer; anda mating member for connecting with a tow ball of a tow hitch,wherein the mating member includes a chamber disposed therein for housing the tow ball in a first position and in a second position, the first position horizontally adjacent the second position,wherein when the tow ball is in the first position in the chamber, the mating member and the elongated shaft are rigid relative to the tow hitch, andwherein when the tow ball is in the second position in the chamber, the mating member and the elongated shaft are non-rigid relative to the tow hitch. 2. The apparatus of claim 1 wherein the mating member includes a first side defining an open side of the chamber. 3. The apparatus of claim 1 wherein the mating member includes a domed side defining a domed side of the chamber. 4. The apparatus of claim 1 further including first and second opposing apertures disposed in the mating member, wherein the first and second opposing apertures are suitable for receiving a single fastener therethrough. 5. The apparatus of claim 4 wherein the tow ball includes a tow ball aperture suitable for receiving the fastener therethrough. 6. The apparatus of claim 5 wherein when the tow ball is in the first position in the chamber, the fastener is disposed in the first and second opposing apertures of the mating member and in the tow ball aperture of the tow ball. 7. The apparatus of claim 5 wherein when the tow ball is in the second position in the chamber, the fastener is disposed in the first and second opposing apertures of the mating member and adjacent to the tow ball. 8. The apparatus of claim 5 wherein the fastener includes a pin. 9. The apparatus of claim 8 wherein the pin includes a spring loaded pin. 10. The apparatus of claim 1 wherein when the tow ball is in the first position in the chamber, the mating member is flush with the tow hitch. 11. The apparatus of claim 1 wherein when the tow ball is in the second position in the chamber, a clearance is disposed between the mating member and the tow hitch. 12. The apparatus of claim 1 wherein when the tow ball is in the second position in the chamber, the mating member is capable of rotating in any of up, down, left, and right directions relative to the tow hitch. 13. A mating member of a hitch mechanism comprising: a curved side defining a chamber disposed therein for housing a tow ball in a first portion of the chamber or in a second portion of the chamber, the first portion of the chamber horizontally adjacent the second portion of the chamber;a flat side defining an opening of the chamber; andfirst and second opposing apertures disposed in the curved side suitable for receiving a single fastener therein,wherein the first portion of the chamber has a first diameter, and the second portion of the chamber has a second diameter, the first diameter different than the second diameter,wherein the first portion of the chamber is capable of housing a whole tow ball, andwherein the member is rigid relative to the tow ball when the first portion of the chamber houses the whole tow ball. 14. The mating member of claim 13 wherein the first diameter is larger than the second diameter. 15. The mating member of claim 13 wherein the second portion of the chamber is capable of housing a majority of a tow ball such that a portion of the tow ball is not housed by the chamber. 16. The mating member of claim 15 wherein the member is non-rigid relative to the tow ball when the second portion of the chamber houses the majority of the tow ball such that the portion of the tow ball is not housed by the chamber. 17. The mating member of claim 16 wherein the member is capable of rotating in any of up, down, left, and right directions when the member is non-rigid relative to the tow ball. 18.
