  • Patent number: 4912865
    Abstract: A display sign embodying the present invention has a normally vertical display panel having first and second sides and at least one face, between the sides, for information. A base supports the panel. First and second side supports are mounted on the base and are positioned adjacent to the first and second sides, respectively. First and second horizontally spaced apart pivots support the display panel on the first side support and first and second horizontally spaced apart pivots support the display panel on the second side support. The display panel rotates about a first axis of rotation through the first pivots as the display panel is forced to move in a first direction and the display panel rotates about a second axis of rotation through the second pivots, as the display panel is forced to move in a second direction from the vertical.

  • Patent number: 4387520
    Abstract: A holder for holding thin rigid planar signs includes a base having a trough for receiving and seating an edge of the sign. An essentially planar wall extends from the trough against which the sign is urged by a pressure pad in order to maintain the sign in a stationary position. The pressure pad is mounted in the base and has a plurality of blades projecting essentially normal to and abutting the surface of the planar wall. Upon insertion of the sign in the holders, the blades exert a resulting force on the sign to urge the sign flush against the planar wall. By virtue of the seating of the sign edge in the trough, the sign is prevented from rotation away from the wall and out of the holder as a result of wind forces acting on the sign.
