Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
259 words
In a scaffold assembly of the type having a support structure for supporting materials receiving platforms and a separate workman''s platform, the improvement wherein said support structure comprises: a. a first platform support for supporting a materials receiving platform comprising a ground engaging base portion, frame means vertically adjustable with respect to said base portion and defined by a pair of laterally spaced vertically extending leg portions and at least one horizontally extending support beam, b. elongated sleeve means disposed between said leg portions and defining an elongated channel extending transverse to said vertically extending leg portions and parallel to said at least one horizontally extending support beam, said sleeve means being rigidly secured to said frame means immediately adjacent said support beam in a manner which maintains said channel stationary with respect thereto, c. a second platform support laterally movable between a first support position extending from said first platform support for supporting a workman''s platform and a second stored position retractably retained within the confines of said first platform support; said second platform support comprising an elongated horizontal beam for supporting said workman''s platform and telescopically received within the elongated channel of, and supported by, said sleeve means; substantially the entire length of said elongated horizontal beam being disposed within the horizontal span of the pair of laterally spaced leg portions of said frame means when said second platform support is disposed in said second stored position, and d. means for releasably locking said second platform support in the first support position and the second support position.

Claim 3
Dependent Claim
32 words
The improvement as defined by claim 1 wherein said elongated sleeve means has a top surface coplanar with the top support surface of the horizontally extending support beam of said frame means.
Claim 4
Dependent Claim
57 words
The improvement as defined by claim 2 wherein said frame means is further defined by a second horizontally extending support beam; said frame means is in telescoping relationship with said base portion; and said second platform support further comprises a ground engaging leg vertically adjustable with respect to the elongated horizontal beam of said second platform support.
Claim 5
Dependent Claim
44 words
The improvement as defined by claim 3 further including releasable locking means for vertically positioning said frame means with respect to said base portion, said releasable locking means supporting said ground engaging leG when said second platform support is in its second stored position.
