Abstract
Abstract A portable wall assembly includes a plurality of panel members having vertical lateral edges releasably attachable to either square or round supporting posts by means of hook-type mounting clips projecting from the upper and lower portions of each panel vertical edge and insertable within the interior of the supporting posts prior to the actuation of a connector plug in the top thereof which is manipulated to produce expansion of the plug in a manner causing a rigid locking of the panels to the adjacent supporting posts.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
202 words
A portable wall assembly including, a panel element having a vertical side edge, an upright post disposed adjacent said panel edge for supporting same, vertically spaced apart mounting means carried by said panel and projecting from said side edge for support by said post, said mounting means including a top clip overlying the top of said post and having a depending tongue inserted into the upper portion of said post, a cap and plug assembly securing said top clip tongue against vertical and lateral displacement relative to said post, said cap and plug assembly including a top cap plate affixed to a connector plug, said plug of elastomeric material and disposed within said post and including an upper smaller diameter portion disposed above a lower larger diameter portion, said cap plate overlying said top clip tongue when inserted into said post with said tongue disposed above said lower larger diameter portion, and means operable from outside said cap and plug assembly to vertically compress and laterally expand said elastomeric connector plug to retain said cap plate in locking engagement atop said panel top clip as said lower larger diameter portion of said plug is expanded to engage the interior of said post.
Claim 2
Dependent Claim
202 words
A portable wall assembly including, a panel element having a vertical side edge, an upright post disposed adjacent said panel edge for supporting same, vertically spaced apart mounting means carried by said panel and projecting from said side edge for support by said post, said mounting means including a top clip overlying the top of said post and having a depending tongue inserted into the upper portion of said post, a cap and plug assembly securing said top clip tongue against vertical and lateral displacement relative to said post, said cap and plug assembly including a top cap plate affixed to a connector plug, said plug of elastomeric material and disposed within said post and including an upper smaller diameter portion disposed above a lower larger diameter portion, said cap plate overlying said top clip tongue when inserted into said post with said tongue disposed above said lower larger diameter portion, and means operable from outside said cap and plug assembly to vertically compress and laterally expand said elastomeric connector plug to retain said cap plate in locking engagement atop said panel top clip as said lower larger diameter portion of said plug is expanded to engage the interior of said post.
