US 5,363,579 A · Floor type advertising apparatus

Abstract

The floor advertisement apparatus is used in a cavity formed in the floor of a building. A lower holding layer is located and secured in the bottom of the cavity. An upper holding layer with an opening extending therethrough has a transparent layer secured to one side of the upper holding layer. The transparent layer and the upper holding layer are located in the cavity. An advertising layer is secured to the lower side of the transparent layer within the opening for viewing from above. Both of the holding layers may be magnetic material or one can be magnetic material and the other one of metal attracted by magnetic lines of force for removably holding the upper layer to the lower layer. In another embodiment, the transparent layer has a layer of adhesive material secured to its bottom side for removably securing the transparent layer in the cavity. An advertising layer can be removably located below the transparent layer or it can be secured to the bottom side of the transparent layer such that it can be viewed from above.
