A hitch assembly comprises housing that includes a generally cylindrical socket with an inner diameter and a slot along an outer periphery of the socket. A hitch ball includes a base that is selectively received within the socket. The base includes a radial groove that generally aligns with the slot. A sliding member selectively engages the slot and the radial groove to retain the hitch ball within the socket.
1. A hitch assembly comprising:
a generally cylindrical socket with an inner diameter and including a slot along an outer periphery of said socket;
a hitch ball selectively received within said socket and having a radial groove about an outer periphery;
a housing for receiving said socket;
a sliding bar guide;
a spring; and
a generally cylindrical sliding member generally defined by an axis and including a spring attachment portion and a guide portion, wherein said sliding member is selectively guided by said sliding bar guide, said sliding member selectively engages said radial groove to retain said hitch ball within said socket, said sliding member is in double shear to resist pullout of said hitch ball, said spring selectively urges said sliding member to rotate generally about the axis, and said sliding member selectively disengages said radial groove to allow said hitch ball to be removed from said socket.
2. The hitch assembly of claim 1 , wherein said sliding bar guide has a generally cylindrical inner surface that selectively contacts said sliding member.
3. The hitch assembly of claim 1 , wherein said hitch ball selectively disengages said slot to release said hitch ball from said socket.
4. The hitch assembly of claim 1 , wherein a lowermost portion of said hitch ball is adjacent to an upper surface of said housing to provide support to said hitch ball to complement support provided by said socket, when said hitch ball is in an installed position within said socket.
5. The hitch assembly of claim 4 , wherein when said hitch ball is installed within said socket, both elements circumscribe a common axis of rotation, a terminal inner end point of both said slot and said groove being generally equally spaced from said axis of rotation.
6. The hitch assembly of claim 1 , wherein said spring selectively urges said sliding member to translate generally parallel to the axis.
7. A hitch assembly comprising:
a generally cylindrical socket with an inner diameter and including a slot along an outer periphery of said socket;
a hitch ball selectively received within said socket and having a radial groove about an outer periphery;
a housing for receiving said socket;
a sliding bar guide; and
a generally cylindrical sliding member including a spring attachment portion and a guide portion, wherein said sliding member is selectively guided by said sliding bar guide, said sliding member selectively engages said radial groove to retain said hitch ball within said socket, said sliding member selectively disengages said radial groove to allow said hitch ball to be removed from said socket, and wherein said sliding member is in double shear to resist pullout of said hitch ball.
8. The hitch assembly of claim 7 , wherein said hitch ball selectively disengages said slot to release said hitch ball from said socket.
9. The hitch assembly of claim 7 , further comprising a spring, wherein said spring selectively urges said sliding member to rotate generally about the axis.
10. The hitch assembly of claim 9 , wherein said spring selectively urges said sliding member to translate generally parallel to the axis.
11. A hitch assembly comprising:
a generally cylindrical socket with an inner diameter and including a slot along an outer periphery of said socket;
a hitch ball selectively received within said socket and having a radial groove about an outer periphery;
a housing for receiving said socket;
a sliding bar guide having a guide slot formed therein;
a generally cylindrical sliding member generally defined by an axis and including a guide pin extending from the axis, wherein said sliding member is selectively guided by said sliding bar guide between a hitch ball engaged position and a hitch ball disengaged position, said sliding member selectively engages said radial groove to retain said hitch ball within said socket, said sliding member selectively disengages said radial groove to allow said hitch ball to be removed from said socket, and wherein said guide pin is selectively translated within the guide slot as the sliding member translates generally axially within the sliding bar guide.
12. The hitch assembly of claim 11 , further comprising a spring, wherein said spring selectively urges said sliding member to rotate generally about the axis.
13. The hitch assembly of claim 12 , wherein, said spring selectively urges said sliding member to translate generally parallel to the axis.
14. The hitch assembly of claim 11 , wherein the sliding bar guide includes a first axial end surface that selectively interferes with the guide pin to restrict axial translation of the sliding member toward the hitch ball disengaged position.
15. The hitch assembly of claim 11 , wherein the sliding bar guide includes a second axial end surface that selectively interferes with the guide pin to restrict axial translation of the sliding member toward the hitch ball engaged position.
16. The hitch assembly of claim 11 , wherein, said sliding member is in double shear to resist pullout of said hitch ball.
