Abstract: A breakaway coupling for a support structure having a first post and a second post, where the breakaway coupling has a first plate coupled to the first post, a second plate coupled to the second post and breakably coupled to the first plate, and a bearing positioned between the first plate and the second plate having a bearing member located in an opening of the bearing housing and contacting at least one of the first and second plates.

Abstract: A signpost assembly includes a spring-loaded connector designed for connecting a signpost to an anchor member, the signpost being designed to shear off when struck forcefully. The signpost has at least one opening. The connector has a bracket with at least a first support side defining an opening and a second support side, and a base connecting the support sides. The connector also has at least one pin which is spring biased. The pin has an alignment knob at one end. The spring biases the pin between a first compressed position and a second expanded position. The opening in the support side allows the alignment knob to protrude through. The assembled connector is held in place by the spring's tension against the spring side of the stop flanges.
