  • Patent number: 5058300
    Abstract: A signholder subassembly for use with a retaining bracket and a pair of clear, relatively flexible planar pieces. Each of the planar pieces has a face surface and is substantially identical to one another and adapted to be mated to one another and mounted along a bottom edge in the retaining bracket by the subassembly. The subassembly includes an insert capable of holding the planar pieces and is mountable within the retaining bracket. A member is included for biasing the planar pieces toward one another to form a bearing surface therebetween and create a gripping action between the face surfaces of the planar pieces when they are mounted within the insert and the retaining bracket. A member also is included for restraining the insert within the retaining bracket.
