Abstract
Abstract A construction for insuring that the edges of panels used in elevated floor systems do not become loose with handling. The construction comprises serrated surfaces on the tops and bottoms of the panel flanges, which interfit with corresponding complementary serrations on the inner facing surfaces of the channel edge strip. The serrations on the flange also extend under the outer portion of the wear surface covering layer to inhibit loosening.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
The combination, with an access floor panel of the type having a rigid marginal panel flange, and a channel shaped edge strip mounted on said flange, of interfitting rigid longitudinal serrations on the opposite inwardly facing surfaces of the edge strip and the outwardly facing upper and lower surfaces of the rigid marginal panel flange, said interfitting serrations being such that longitudinal inward projections on said edge strip will be received by longitudinal outwardly facing complementary recesses on said marginal panel flange.
Claim 2
Dependent Claim
82 words
The combination, with an access floor panel of the type having a rigid marginal panel flange, and a channel shaped edge strip mounted on said flange, of interfitting rigid longitudinal serrations on the opposite inwardly facing surfaces of the edge strip and the outwardly facing upper and lower surfaces of the rigid marginal panel flange, said interfitting serrations being such that longitudinal inward projections on said edge strip will be received by longitudinal outwardly facing complementary recesses on said marginal panel flange.
Claim 3
Dependent Claim
29 words
The combination according to claim 1, said marginal panel flange comprising a composite flange made up of the margins of an upper load receiving panel and a lower panel.
Claim 4
Dependent Claim
61 words
The combination according to claim 2, said access floor panel further comprising a wear surface covering layer, the upper serrations on said marginal panel flange also being present under the outer margins of said wear surface covering layer, and adhesive filling the interstices of said last mentioned serrations and thereby securing the margins of said wear surface covering layer in place.
