Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
250 words
A movable panel assembly comprising a frame defining a perimeter and including generally vertical frame members and a generally horizontal lower frame member: support means operable to hold said frame members in an assembly defining an interior space; said vertical frame members comprising channel shaped members having a base and side walls, the sidewalls having inturned ends spaced from the base and defining an opening facing away from the space defined by the perimeter frame; sheet means extending across said space to form a support resisting forces perpendicular to the plane of the perimeter frame; a layer of fabric over said sheet means; retainer means on each of the edges of the frame members comprising a plurality of teeth extending in direction relative to the frame so that edge portions of the fabric layer placed over the teeth under tension are retained by the teeth, and a pair of support feet mounted on the lower horizontal frame member, a raceway having a lower wall and hingedly attached side walls, means to mount the lower wall of the raceway to the support feet with the raceway side walls extending upwardly to position adjacent the lower frame member to form an enclosure in cooperation with the lower frame member, said raceway side walls having inturned side edges adjacent the lower frame member, and cooperating grooves and lip means acting between the inturned edges of the raceway sidewalls and the support feet to releasably retain the raceway sidewalls uprightly on the support feet.
Claim 2
Dependent Claim
250 words
A movable panel assembly comprising a frame defining a perimeter and including generally vertical frame members and a generally horizontal lower frame member: support means operable to hold said frame members in an assembly defining an interior space; said vertical frame members comprising channel shaped members having a base and side walls, the sidewalls having inturned ends spaced from the base and defining an opening facing away from the space defined by the perimeter frame; sheet means extending across said space to form a support resisting forces perpendicular to the plane of the perimeter frame; a layer of fabric over said sheet means; retainer means on each of the edges of the frame members comprising a plurality of teeth extending in direction relative to the frame so that edge portions of the fabric layer placed over the teeth under tension are retained by the teeth, and a pair of support feet mounted on the lower horizontal frame member, a raceway having a lower wall and hingedly attached side walls, means to mount the lower wall of the raceway to the support feet with the raceway side walls extending upwardly to position adjacent the lower frame member to form an enclosure in cooperation with the lower frame member, said raceway side walls having inturned side edges adjacent the lower frame member, and cooperating grooves and lip means acting between the inturned edges of the raceway sidewalls and the support feet to releasably retain the raceway sidewalls uprightly on the support feet.
Claim 3
Dependent Claim
40 words
The movable panel assembly of claim 1 wherein the perimeter frame comprises metal frame members having raised ribs on the sides thereof, said sheet means including expanded metal sheets welded to the ribs on opposite sides of the frame members.
Claim 4
Dependent Claim
41 words
The movable panel assembly of claim 1 wherein said sheet means includes a separate sheet member fastened to the perimeter frame on each side thereof, and a layer of resilient material positioned to the exterior of each of the sheet members.
Claim 5
Dependent Claim
61 words
The movable panel assembly of claim 1 wherein the vertical frame members having straps forming receptacles on the base of the vertical frame members facing inwardly toward the defined space, and a plurality of cross members extending between the vertical frame members, said cross members having tabs which fit into the receptacles and which are retained by the straps for assembly.
Claim 6
Dependent Claim
138 words
In a panel construction for movable panels having a perimeter frame, including a generally horizontal lower frame member, the improvement comprising support feet members, means to clamp said support feet members to said lower frame member at spaced locations thereon, and a raceway housing comprising a bottom wall, and upright side walls means on said bottom wall to permit said raceway housing to be supported on the lower portions of said support feet members, said side walls extending generally uprightly from said bottom wall and being hingedly attached thereto, and cooperating lip and groove means between the support feet members and the side walls adjacent the upper edges of said side walls to permit releasably latching said side walls to said support feet members when the support feet members are clamped in place on said lower frame member.
Claim 7
Dependent Claim
138 words
In a panel construction for movable panels having a perimeter frame, including a generally horizontal lower frame member, the improvement comprising support feet members, means to clamp said support feet members to said lower frame member at spaced locations thereon, and a raceway housing comprising a bottom wall, and upright side walls means on said bottom wall to permit said raceway housing to be supported on the lower portions of said support feet members, said side walls extending generally uprightly from said bottom wall and being hingedly attached thereto, and cooperating lip and groove means between the support feet members and the side walls adjacent the upper edges of said side walls to permit releasably latching said side walls to said support feet members when the support feet members are clamped in place on said lower frame member.
Claim 8
Dependent Claim
