Abstract
Abstract A floor assembly is provided which is formed from a plurality of downwardly-open channel members arranged in parallel spaced relation and interconnected by means of pairs of adjacent connecting straps which are moved into position from opposite directions transverse to the longitudinal axes of the channels whereby attachment ears on the straps engage over edge flanges on the channel members. The connecting straps may have aligned keyways in them for receiving locking keys which lock the straps and the channel members together to form a rigid floor assembly.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A floor comprising a plurality of downwardly-open channel members in paraLlel spaced relation, each channel member having a load-carrying web, substantially vertical legs and inwardly projecting edge flanges, the channels being interconnected by means of pairs of adjacent connecting straps which are moved into position from opposite directions transverse to the longitudinal axes of the channels, each connecting strap of each pair having an attachment ear engaged over one edge flange on each channel on the same side of each channel, with the ears on adjacent straps engaging opposite edge flanges, and with adjacent straps further having aligned transverse keyways therein with locking keys secured in the aligned keyways to lock the straps and channel members together in the form of a rigid floor assembly.
Claim 2
Dependent Claim
125 words
A floor comprising a plurality of downwardly-open channel members in paraLlel spaced relation, each channel member having a load-carrying web, substantially vertical legs and inwardly projecting edge flanges, the channels being interconnected by means of pairs of adjacent connecting straps which are moved into position from opposite directions transverse to the longitudinal axes of the channels, each connecting strap of each pair having an attachment ear engaged over one edge flange on each channel on the same side of each channel, with the ears on adjacent straps engaging opposite edge flanges, and with adjacent straps further having aligned transverse keyways therein with locking keys secured in the aligned keyways to lock the straps and channel members together in the form of a rigid floor assembly.
Claim 3
Dependent Claim
45 words
A floor as set forth in claim 1 in which each of said keyways is an upwardly open channel with flanges along opposite sides thereof, and each of said locking keys has tabs thereon which are crimped to secure each such key in a keyway.
Claim 4
Dependent Claim
31 words
A floor as set forth in claim 1 in which said load-carrying web on each channel has a non-slip upper surface comprising a plurality of longitudinally extending ribs on the surface.
Claim 5
Dependent Claim
22 words
A floor assembly as set forth in claim 1 in which legs on said channels are inclined inwardly from top to bottom.
Claim 6
Dependent Claim
50 words
A floor assembly as set forth in claim 1 in which each pair of connecting straps interconnects less than all of the channel members in the floor assembly and the pairs of straps are overlapped with respect to the channels to interconnect all of the channels in the floor assembly.
Claim 7
Dependent Claim
37 words
A floor assembly as set forth in claim 1 in which the connecting straps have upwardly projecting lugs thereon which engage the channel edge flanges opposite the attachment ears to prevent horizontal rotation of the connecting straps.
