A wind responsive sign or placard for displaying advertising or other visual indicia includes a rotatable member that is attached to a stationary mounting member by a rod extending between the two members. Both the rotatable or spinning member and the stationary mounting member are formed of fluted or corrugated panels, and the axle rod extends into aligned flutes or channels in the two principal components. These panels are fabricated from extruded plastic panels of the type suitable for exterior use. The panel forming the mounting member is folded to form a three dimensional structure that is more rigid than the flat rotatable panel. The sign formed in this manner is relatively light in weight and can be assembled on site and can be mounted to a pole or post in an elevated position.
A sign comprising a spinning member secured to a mounting member by an axle, the sign being characterized in that the axle is attached to the mounting member adjacent one end thereof and the axle is attached to the spinning member along an axis of rotation of the spinning member, the mounting member including two diverging sides, for imparting rigidity, with aligned recesses in the two diverging sides configured to provide clearance for the spinning member.
A lightweight display that can be mounted on a surface including a turning member secured to a mounting member by at least one longitudinal support extending between the mounting member and the turning member, both the mounting member and the turning member being formed by fluted panels, with the longitudinal support being positioned in adjacent flutes in the mounting member and the turning member, so that the turning member is free to move in response to wind currents relative to the mounting member.
A placard for displaying visual indicia comprising a first panel and a second panel, the second panel being cut from the first panel to form an opening in the first panel, the first panel being folded to form a three dimensional support member for the second panel with a portion of the opening being located along one side of the three dimensional support member with the second panel being supported partially in the portion of the opening on one side of the support member by at least one rod extending between the support member and the second panel.
