Anti-rotational hitch ball
A hitch assembly that includes an anti-rotation mechanism. The hitch assembly generally includes a hitch ball, a ball mount, and a fastener. The invention is directed to a mechanism for preventing rotation of either the hitch ball or the fastener relative to the ball mount. The anti-rotation mechanism of the present invention provides an engagement means for interlocking sections of the hitch ball or fastener with the ball mount, thereby blocking rotation of the hitch ball or fastener relative to the ball mount.
1. A hitch assembly comprising:
a hitch ball comprising a flange defining a top surface, a bottom surface, and an outer side surface and at least one pin opening defined within the outer side surface;
a ball mount adapted for receiving the hitch ball; wherein the ball mount comprises an upper side surface and at least one pin opening defined within the upper side surface; and
a pin that engages both the at least one pin opening in the hitch ball and the at least one pin opening in the ball mount, thereby inhibiting rotational movement of the hitch ball relative to the ball mount.
2. A hitch assembly according to claim 1 wherein the pin is affixed within the at least one pin opening defined within the hitch ball.
3. A hitch assembly according to claim 1 wherein the pin is affixed within the at least one pin opening defined within the ball mount.
4. A hitch assembly comprising:
a hitch ball having a flange defining a top surface, a bottom surface, and an outer side surface and a pin engaging recess defined by said outer side surface;
a ball mount adapted for receiving said hitch ball, said ball mount having at least one pin; and
wherein said pin engages said pin engaging recess, thereby inhibiting rotational movement of said hitch ball relative to said ball mount.
5. The hitch assembly of claim 4 wherein said pin engaging recess is concave.
6. The hitch assembly of claim 4 wherein said pin engaging recess and said pin are contiguous.
7. A hitch ball adapted for mounting to a ball mount having an extending pin, said hitch ball comprising:
a ball; and
a base integrally formed to said ball and defining a top surface, a bottom surface, and an outer side surface, said outer side surface defining a pin engaging recess;
wherein said pin engaging recess is adapted to engage said pin, thereby inhibiting rotational movement of said hitch ball relative to said ball mount.
8. The hitch ball of claim 7 wherein said pin engaging recess is concave.
9. A method of attaching a hitch ball to a ball mount comprising:
inserting a hitch ball having a top surface, a bottom surface, an outer side surface defined between said top and bottom surfaces, and a shank into a ball mount shank opening;
aligning a pin engaging recess defined by said outer side surface of said hitch ball with a pin extending from an upper surface of said ball mount; and
engaging said pin with said pin engaging recess.
10. The method of claim 9 further comprising visually verifying said pin is engaged with said pin engaging recess by observing a portion of said pin enclosed within said pin engaging recess.
11. The method of claim 9 further comprising attaching a fastener to said shank of said hitch ball.
