US4296579A — Screen panel

Claim 1

Independent Claim 259 words

A screen panel comprising: (a) a frame for said panel, said frame having a closed perimeter and defining front and rear planar surfaces spaced apart in a front to rear direction and extending in parallel lateral planes. (b) a plurality of clips fixed to said frame and spaced around the perimeter of said frame, some of said clips being associated with said front surface and some of said clips being associated with said rear surface, each clip having a support portion extending in said front to rear direction beyond its associated front or rear surface and a retainer portion extending from the outer end of said support portion and directed outwardly in a direction having a component parallel to a said lateral plane, (c) two sleeves, each sleeve having: (i) a self supporting subframe formed from a resilient wire rod which defines a closed perimeter, (ii) a fabric material extending across said subframe and covering said wire rod, (d) said wire rod of one sleeve being fitted over said support portions of said clips associated with said front surface and said wire rod of the other sleeve being fitted over said support portions of said clips associated with said rear surface, whereby a said sleeve may be removed from said panel by deforming a portion of its wire rod in a direction generally laterally outwardly to move such portion clear of the retaining portion of a clip on which such portion is fitted, and then moving such portion outwardly in a front to rear direction, away from said frame.

Claim 2

Dependent Claim 259 words

A screen panel comprising: (a) a frame for said panel, said frame having a closed perimeter and defining front and rear planar surfaces spaced apart in a front to rear direction and extending in parallel lateral planes. (b) a plurality of clips fixed to said frame and spaced around the perimeter of said frame, some of said clips being associated with said front surface and some of said clips being associated with said rear surface, each clip having a support portion extending in said front to rear direction beyond its associated front or rear surface and a retainer portion extending from the outer end of said support portion and directed outwardly in a direction having a component parallel to a said lateral plane, (c) two sleeves, each sleeve having: (i) a self supporting subframe formed from a resilient wire rod which defines a closed perimeter, (ii) a fabric material extending across said subframe and covering said wire rod, (d) said wire rod of one sleeve being fitted over said support portions of said clips associated with said front surface and said wire rod of the other sleeve being fitted over said support portions of said clips associated with said rear surface, whereby a said sleeve may be removed from said panel by deforming a portion of its wire rod in a direction generally laterally outwardly to move such portion clear of the retaining portion of a clip on which such portion is fitted, and then moving such portion outwardly in a front to rear direction, away from said frame.

Claim 3

Dependent Claim 21 words

A panel according to claim 1 and including a sound absorbing material disposed between said sleeves and retained by said sleeves.

Claim 4

Dependent Claim 38 words

A panel according to claim 1 wherein said fabric material includes an outer fabric layer and an inner padding layer, said layers being slit to expose the inner surface of said rod at the location of said clips.

Claim 5

Dependent Claim 139 words

A panel according to claim 3 wherein said panel and said sleeves are all substantially rectangular, said frame including a pair of vertical edge members and a pair of vertical extending channel members on fixed over each edge member and disposed with a said sleeve between them, said channel members having opposed inner channel openings facing the vertical edges of said sleeve located between them, said channel members being spaced laterally from said vertical edges of said sleeve located between them, the spacing between the front and rear inner edges of said channel members and the adjacent vertical edges of said sleeves being small, so that a wire may be forced through such spacing into a said channel opening and so that said fabric material will deform as said wire is so inserted, to accommodate passage of said wire.

Claim 6

Dependent Claim 76 words

A panel according to claim 4 and further including a further channel member fixed to a lower horizontal edge of said frame; said further channel member being spaced slightly below the bottom edges of said sleeve and having upwardly facing inner front and rear channel openings for receiving and retaining cables, the inner front and rear edges of said last mentioned channel openings being spaced from the bottom edges of said sleeves by said small spacing.

Claim 7

Dependent Claim 61 words

A panel according to claim 4 wherein each vertical edge member includes a plurality of vertically aligned vertical slots therein in its front face located between a said channel member and the vertical edge of the sleeve adjacent such channel member, said slots thereby being accessible from the front of said panel, and said slots being adapted to receive shelving brackets.
