Abstract
An improved sign stand for flexible traffic control signage is provided which includes a cam assembly for quickly securing a sign to the stand without sacrificing the holding force generated thereby. The sign stand includes a base assembly for temporarily erecting the sign at a desirable location, and an elongated upright extending from the base assembly. A cam assembly is supported by the upright for releasably securing a vertical brace member of a flexible sign. The cam assembly includes a rotatable cam member and a compliant member interdisposed between the cam member and the upright which is operably associated therewith to elastically yield in response to rotation of the cam member, thereby generating a clamping force between the upright and the cam assembly to releasably secure the vertical brace member to the stand. Various modifications to the preferred embodiment are also disclosed which further enable the improved sign stand to accommodate vertical brace members of varying thickness without sacrificing the holding force generated between the sign stand and the sign.
