Independent Claim
137 words
A system for supporting one or a number of standardized furniture components as desks, tops, cabinets or the like comprising: a supported member; end panel members adapted to support said supported member; first securing means in said end panels and said supported member for releasably securing same together; cover members for said end panels; second securing means in said cover members and said end panels for releasably securing said cover to said panel; and said end panel including an inner wall and an outer wall section, said inner wall having a generally flat, planar surface, said outer wall having flat planar peripheral edge portions and an outwardly formed central portion, said outer peripheral portions being secured to said inner wall and said central portions extending outwardly from said inner wall to thereby provide a rigid panel structure.
Claim 10
Independent Claim
137 words
A system for supporting one or a number of standardized furniture components as desks, tops, cabinets or the like comprising: a supported member; end panel members adapted to support said supported member; first securing means in said end panels and said supported member for releasably securing same together; cover members for said end panels; second securing means in said cover members and said end panels for releasably securing said cover to said panel; and said end panel including an inner wall and an outer wall section, said inner wall having a generally flat, planar surface, said outer wall having flat planar peripheral edge portions and an outwardly formed central portion, said outer peripheral portions being secured to said inner wall and said central portions extending outwardly from said inner wall to thereby provide a rigid panel structure.
Claim 11
Dependent Claim
56 words
The system as defined in claim 8 and further including an outer peripheral edge extending outwardly from said inner wall section parallel to said central portion of said outer wall section, said central portion, said outer peripheral edge and said flat planar peripheral portions of said outer wall forming a wire-receiving channel in said end panel.
Claim 12
Dependent Claim
230 words
The system as defined in claim 9 wherein said second securing means comprises a lock member slideably mounted in said cover and lock-engaging means on said outer wall adapted to engage with said lock member; said lock member comprises a bar slideably mounted in said cover, a plurality of tab members having engaging means formed thereon extending outwardly from said bar, and wherein said lock-engaging means includes a plurality of tab receiving slots formed in said outwardly extending central portion of said outer wall; biasing means for said lock member, said biasing means urging said tab members toward locked position with respect to said tab-receiving slots in said panel; said engaging means on each said tab member comprises a barb on said tab defining first and second shoulders on either side thereof respectively, said first shoulder being positioned farther from said barb than said second shoulder; means on said tab for securing said bias means thereto; means on said cover for securing said bias means to said cover on either side of said tab whereby said tab will be locked in said slot either by said first shoulder or said second shoulder and said barb can be used with either a panel having no fabric wrapped around its edges or a panel having fabric simply by connecting said bias means to said cover on an appropriate side of said tab.
