Abstract An acoustical insulating fiber panel having two pairs of parallel edges, elongated extruded framing members extending along the edges of the panel, each framing member being rigid and including a first web portion adapted to engage the edge of the panel, a first flange at right angles to the web for engaging the suspension hanger-flanges, a second flange extending as a projection of the lower surface of the panel and extending a short distance beyond the projection of the first flange. The second flange has further webs extending inwardly of the flange at 90° thereto and forms a material receiving jaw. An aesthetic covering material is stretched across the lower surface of the acoustical fiber panel and engages said so-formed jaws on the second flange of said framing members, and locking means are provided within the jaws for holding the edges of the covering material.
An acoustical ceiling panel comprising an acoustical insulating fiber panel having two pairs of parallel edges, elongated framing members extending along the edges of the panel, each framing member being rigid and including a first web portion adapted to engage the edge of the panel, a first flange at right angles to the web for engaging suspension hanger-flanges, a second flange extending as a projection of the lower surface of the panel and extending a short distance beyond the projection of the first flange, the second flange having further flanges extending at 90° thereto forming a material receiving slot, an aesthetic covering material stretched across the lower surface of the acoustical fiber panel and engaging said material receiving slot on the second flange of the framing members, and locking means within the slot for holding the edges of the covering material in the slot.

An acoustical ceiling panel comprising an acoustical insulating fiber panel having two pairs of parallel edges, elongated framing members extending along the edges of the panel, each framing member being rigid and including a first web portion adapted to engage the edge of the panel, a first flange at right angles to the web for engaging suspension hanger-flanges, a second flange extending as a projection of the lower surface of the panel and extending a short distance beyond the projection of the first flange, the second flange having further flanges extending at 90° thereto forming a material receiving slot, an aesthetic covering material stretched across the lower surface of the acoustical fiber panel and engaging said material receiving slot on the second flange of the framing members, and locking means within the slot for holding the edges of the covering material in the slot.
Claim 3
Dependent Claim
69 words
A panel as defined in claim 1, wherein the framing members are made of extruded metal material, such as aluminum, a pair of short flanges extending inwardly and opposed to each other from the first and second flanges spaced close to the web of the framing member, and a frame locking means adapted to be engaged between the latter flanges for fixing the adjacent framing members at each corner.
Claim 4
Dependent Claim
39 words
A panel as defined in claim 1, wherein the locking means within the slot includes a resilient elongated rope-like member forced between the flanges and the covering material to hold the edges of the covering material between the flanges.
