Abstract
Abstract A readily erectable and dismantleable structure for exhibition purposes consists of a base element having upturned front and end flanges adapted to be secured to a base to define locating means for a yieldable thin-walled panel having the lower extremities of the central portion extending along and behind the upturned front flange and along and behind the end flanges, there being an identical cap element for the thin-walled panel, contiguous sections being joined at the end flanges of the base and cap elements.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
238 words
In a readily erectable and dismantleable structure for exhibition purposes: a. a base element having upturned front and end flanges; b. said base element being detachable secured to a fixed base; c. a yieldable thin-walled panel supported by said base element and having a central panel portion and end panel portions extending from said central portion; d. said panel having its central panel portion extending along and behind said upturned front flange and having the lower extremities thereof protected thereby; e. said end panel portions extending along said end flanges and being held thereagainst; f. elements spaced along said base and at the ends thereof and spaced from said front and end flanges and cooperating with said front and end flanges to receive said central portions of said panel and end portions thereof; g. a cap element identical to said base element and having downturned front and end flanges; i. said downturned front flange extending over upper extremities of said central panel portion; ii. said downturned end flanges extending along the end panel portions; iii. said downturned front and end flanges being provided with elements spaced therefrom and cooperating with said front and end flanges to receive central and end portions of said panel; h. means securing base elements together; i. means securing cap elements together; j. said base and cap elements extending along predetermined geometric patterns to provide a structure of like geometric configuration in plan view.
