Abstract
Abstract A modular structural assembly is formed from a frame assembly and a plurality of rectangular panels which are releasably secured to the frame. Each panel is formed from four struts which are interconnected and a sheet which is stretched over the struts and secured thereto. Each strut includes an outwardly extending flange which is secured to the frame by clips mounted on the frame.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
105 words
A modular structural assembly comprising an outer frame, a plurality of panels, and a plurality of clips for releasably securing the panels to the outer frame, the outer frame including a plurality of spaced-apart frame members, each panel comprising four struts connected to form a generally rectangular panel frame and a sheet secured to the struts, each strut including an elongated body and a longitudinally extending flange extending outwardly from the body, the sheet of each panel being folded over the flanges of the panel and being secured thereto, the clips being secured to the frame members and frictionally engaging the flanges of the panels.
Claim 2
Dependent Claim
105 words
A modular structural assembly comprising an outer frame, a plurality of panels, and a plurality of clips for releasably securing the panels to the outer frame, the outer frame including a plurality of spaced-apart frame members, each panel comprising four struts connected to form a generally rectangular panel frame and a sheet secured to the struts, each strut including an elongated body and a longitudinally extending flange extending outwardly from the body, the sheet of each panel being folded over the flanges of the panel and being secured thereto, the clips being secured to the frame members and frictionally engaging the flanges of the panels.
Claim 3
Dependent Claim
36 words
The structure of claim 1 in which the body of each of the struts is tubular and adjacent struts of a panel are connected by an L-shaped connector which is inserted into each of the struts.
Claim 4
Dependent Claim
46 words
The structure of claim 1 in which each strut is formed from a rolled sheet of metal which is rolled to form a tubular body having a generally rectangular cross section and a flange which extends from one of the sides of the rectangular cross section.
Claim 5
Dependent Claim
30 words
The structure of claim 1 in which the sheet of each panel is secured to the flanges of at least three of the struts of the panel by said clips.
Claim 6
Dependent Claim
45 words
The structure of claim 1 in which some of the panels are bounded on three sides by frame members and are bounded on the fourth side by an adjacent panel, the flanges of adjacent struts of said adjacent panels being releasably secured together by clips.
Claim 7
Independent Claim
102 words
A method of assembling a modular structural assembly comprising the steps of: a. erecting an outer frame having a plurality of spaced-apart frame members, b. forming a plurality of rectangular panel frames by interconnecting four struts, each of the struts having an elongated body and a longitudinally extending flange extending outwardly from the body, c. forming a plurality of panels by extending a sheet over each of the panel frames, folding the sheet over each flange of the panel, and securing the sheet to each flange, and d. inserting each panel between a pair of frame members and securing the panel thereto.
Claim 8
Independent Claim
102 words
A method of assembling a modular structural assembly comprising the steps of: a. erecting an outer frame having a plurality of spaced-apart frame members, b. forming a plurality of rectangular panel frames by interconnecting four struts, each of the struts having an elongated body and a longitudinally extending flange extending outwardly from the body, c. forming a plurality of panels by extending a sheet over each of the panel frames, folding the sheet over each flange of the panel, and securing the sheet to each flange, and d. inserting each panel between a pair of frame members and securing the panel thereto.
Claim 9
Dependent Claim
30 words
The method of claim 6 in which the sheet of each panel is secured to the flanges of the panel frame by inserting clips over the sheet and the flanges.
Claim 10
Dependent Claim
33 words
The method of claim 6 in which each panel is secured to the frame members by inserting at least two of the flanges of the panel into clips attached to the frame member.
Claim 11
Dependent Claim
77 words
The method of claim 6 in which the sheet of each panel is secured to the flanges of the panel frame by inserting flange clips over the sheet and the flanges and each panel is secured to the frame members by inserting at least two of the flanges of the panel into panel clips attached to the frame member, and removing at least some of the flange clips after the flanges are inserted into the panel clip.
