Abstract
A ceiling panel according to the present invention has opposed translucent membranes secured in a tensioned state across a perimeter frame. The frame includes frame members that are designed to oppose inward bowing of the perimeter frame caused by the tensioned membranes. The frame members have a side profile shaped to conceal a grid support network with the lower translucent member extending across and about a lower edge of the perimeter frame. The invention also includes a modified structure for supporting of translucent panels below a grid network.
Claims20
A ceiling or wall panel for securement to a grid support network, the panel comprising:
- a perimeter frame, a first membrane secured across the perimeter frame, and a second membrane secured across the perimeter frame and opposing the first membrane, the perimeter frame including connected frame members, each frame member comprising:
- an outwardly stepped edge with the first membrane wrapped over the outwardly stepped edge,
- a securing edge with the second membrane wrapped over the securing edge at a position that is inward of the outwardly stepped edge, and
- an inwardly projecting stiffening member joining the outwardly stepped edge and the securing edge, the stiffening member being shaped to oppose inward bowing of the frame member caused by tension of the membranes across the perimeter frame, the stiffening member including:
- a first diagonal arm extending from the outwardly stepped edge,
- a second diagonal arm extending from the securing edge, and
- a curved segment joining the first diagonal arm and the second diagonal arm at a point between the first and second membranes.
A ceiling or wall panel for securement to a grid support network, the panel comprising:
- a perimeter frame, a first membrane secured across the perimeter frame, and a second membrane secured across the perimeter frame and opposing the first membrane, the perimeter frame including connected frame members, each frame member comprising:
- an outwardly stepped edge with the first membrane wrapped over the outwardly stepped edge,
- a securing edge with the second membrane wrapped over the securing edge at a position that is inward of the outwardly stepped edge, and
- an inwardly projecting stiffening member joining the outwardly stepped edge and the securing edge, the stiffening member including:
- a first diagonal arm extending inward from the outwardly stepped edge, and
- a second diagonal arm extending inward from the securing edge,
- wherein the first diagonal arm and the second diagonal arm are joined at a location between the first and second membranes.
A ceiling or wall panel for securement to a grid support network, the panel comprising:
- a perimeter frame, a first membrane secured across the perimeter frame, and a second membrane secured across the perimeter frame and opposing the first membrane, the perimeter frame including connected frame members, each frame member comprising:
- an outwardly stepped edge with the first membrane wrapped over the outwardly stepped edge,
- a securing edge with the second membrane wrapped over the securing edge at a position that is inward of the outwardly stepped edge, and
- an inwardly projecting stiffening member joining the outwardly stepped edge and the securing edge, the stiffening member being shaped to oppose inward bowing of the frame member caused by tension of the membranes across the perimeter frame,
- wherein each outwardly stepped edge is less than one inch in width and is of a triangular shape with a lower edge of the triangular shape including a membrane wrap edge with a membrane securing cavity that is above the wrap edge and is located inward relative to an outside edge of the panel, and wherein the triangular shape forms a lower edge portion of the stiffening member.
