发明名称 Multi-Function Anti-Rotational/Anti-Theft Hitch Ball Assembly
摘要 The multi-function anti-rotational/anti-theft hitch ball assembly of the present invention provides a trailer hitch assembly that includes an anti-rotational hitch ball mechanism that can also serve as an anti-theft hitch ball mechanism and can further simultaneously function as an attachment method for securing additional hitch accessories to the ball mount. The invention provides an engagement method for interlocking the hitch ball with the ball mount preventing rotation of the hitch ball relative to the ball mount. The interlocking engagement assembly may also be locked in place preventing the hitch ball from being removed from the ball mount if the hitch ball fastener is removed. In addition, a component of the assembly can serve as an attachment method for securing additional accessories to the ball mount.
