Patent ID: 8191746

Claim:
A tow-bar mountable device for carrying items on a tow-bar having a tow-ball engaged with the tow-bar which comprises: a first-part which has a platform to which other items are attached in a permanent or releasable manner, having a web portion joining a pair of downwardly extending first and second lugs relative to the tow-ball such that the web portion of the first part has an aperture larger than the diameter of the tow-ball allowing the web portion of the first part to be placed over the tow-ball, the first and second lugs each having a single aperture therethrough; a second-part that is placed into a fixed position on said tow-bar by a stem and a securing-nut of said tow-ball, the second part having a web portion joining a pair of downwardly extending first and second lugs relative to the tow-ball, the first and second lugs of the second part each having a single aperture therethrough; a means-to-secure said first-part to said second-part where said means-to-secure is a single hitching-pin that links said first-part to said second-part by extending through the apertures of each of the first and second lugs of both the first and the second parts and thereby limits movement, of said first-part relative to said second-part, to rotation of said first-part about an axis of said hitching-pin; wherein said first-part engages with said tow-ball to restrict rotation in both directions of said first-part about said axis of the said hitching-pin or, alternatively, in only one direction while rotation in an opposite direction to said one direction is restricted by said first-part contacting said second-part remote from said hitching-pin; wherein further said first-part engaging with said tow ball, to restrict rotation, of said first-part about said axis of said hitching-pin, does not require friction between said first-part and said tow-ball; wherein further said second-part is fixed to said tow-bar by passing said stem through a hole in said web portion of said second part, then through a hole in said tow-bar.
