Abstract

A cavity is formed in the floor of a building for receiving the floor type advertising apparatus. A magnetic layer is located and secured in the lower portion of the cavity. A metal layer having an opening formed therethrough is attached to the lower side of a transparent layer and both the transparent layer and the metal layer are located in the cavity to allow the magnetic lines of force from the magnetic layer to removably secure the transparent layer and the metal layer in the cavity. In one embodiment, the lower holding layer has an opening formed therethrough in which is located an advertising layer which can be seen from above through the opening and through the transparent layer. In another embodiment, the metal layer and the magnetic layer may be reversed in positions. In a further embodiment wherein the magnetic frame layer is bonded to the transparent layer and the metal layer is bonded to the bottom of the cavity, one side of the frame is bonded to one side of the lower metal layer whereby the other side of the magnetic frame layer with the transparent layer may be lifted from the lower layer and folded back to allow insertion or removal of the advertising layer.

Dependent claims

A floor type advertising apparatus, comprising:

a floor,
a cavity formed in said floor,
said cavity having a lower portion,
a thin lower holding layer located in and secured in the lower portion of said cavity,
said lower holding layer having an upper side,
a thin upper holding layer located in said cavity and having an opening formed therethrough,
said upper holding layer having an upper side and a lower side,
a thin transparent layer of material in sheet form having a bottom side securely coupled to the upper side of said upper holding layer and having dimensions such that said transparent layer of material covers the opening of said upper holding layer,
said transparent layer of material having an upper side,
said transparent layer of material and said upper holding layer being located in said cavity with the lower side of said upper holding layer facing the upper side of said lower holding layer and the upper side of said transparent layer of material facing upward and being about flush with the level of the floor when located in said cavity,
an advertising layer located in said cavity below said transparent layer of material,
said transparent layer of material and said upper holding layer being movable relative to said lower holding layer for receiving said advertising layer below said transparent layer of material,
said opening formed through said upper holding layer being sufficient to allow the desired advertisement of said advertising layer to be seen through said opening and through said transparent layer of material when viewed from above,
one of said holding layers comprising magnetic material forming magnetic lines of force and the other of said holding layers being formed of a material which is attracted by the magnetic lines of force from said magnetic material.
