Abstract

Disclosed herein is a portable panel having numerous favorable characteristics. The panel comprises a core having a length, a width, a first side and a second side. A first fiber layer is attached to the first side while a second fiber layer is attached to the second side. A first polyurethane layer is impregnated in the first fiber layer while a second polyurethane layer is impregnated into the second fiber layer. A first skin is attached to the first polyurethane layer while a second skin is attached to the second polyurethane layer. The panel can be used in the manufacture of tables, flooring, risers, stages, bleachers, and the like.

Claims (17)

1. A reversible portable floor, the reversible portable floor comprising

a plurality of panels, each panel including:

a core having a length, a width, a first side and a second side;

a first fiber layer attached to the first side;

a second fiber layer attached to the second side;

a first polyurethane layer impregnating the first fiber layer;

a second polyurethane layer impregnating the second fiber layer;

a first skin attached to the first polyurethane layer, the first skin having a first appearance;

a second skin attached to the second polyurethane layer, the second skin having a second appearance;

a frame surrounding the core, the frame including a female side and a male side, the female side including a engaging section and a channel having a channel length substantially equal to the core length, the male side including a protrusion shaped to engage the channel and a locking mechanism, the protrusion having a protrusion length substantially equal to the channel length; and

a first flooring side configuration when the first skin is positioned up and a second flooring side configuration when the second skin is positioned up, each flooring side configuration positionable as an exposed floor for pedestrian traffic.

2. The reversible portable floor of claim 1 , wherein the frame is metallic.

3. The reversible portable floor of claim 1 , wherein the protrusion of the male side of one panel engages the channel of an adjacent panel to restrict movement of the one panel in relation to the adjacent panel.

4. The reversible portable floor of claim 3 , wherein the engagement between the protrusion and the channel restricts the relative vertical movement of the one panel in relation to the adjacent panel.

5. The reversible portable floor of claim 3 , wherein the engagement between the protrusion and the channel restricts both rotational and vertical movement of the one panel in relation to the adjacent panel.

6. The reversible portable floor of claim 5 , wherein the engagement between the protrusion and the channel restricts lateral movement of the one panel in relation to the adjacent panel.

7. The reversible portable floor of claim 5 , further including at least one protrusion located on the female side and at least one aperture located on the male side shaped to accept the aperture, the engagement of the protrusion and the aperture suppresses lateral movement of the one panel in relation to the adjacent panel.
