Portable panel construction and method for making the same
View Patent ↗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.
1. A portable floor, the 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;
a second skin attached to the second polyurethane layer;
a frame surrounding the core, the frame including a female side and a male side, the female side including an 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;
wherein the protrusion of the male side of a first panel engages the channel of an adjacent panel to restrict lateral movement of the first panel in relation to the adjacent panel;
wherein the engagement between the protrusion and the channel restricts both rotational and vertical movement of the first panel in relation to the adjacent panel; and
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 first panel in relation to the adjacent panel.
2. The portable floor of claim 1 , wherein the frame is metallic.
