Abstract
Abstract A raceway forming member for use with a cellular or non-cellular flooring unit having at least two longitudinal, spaced-apart, inverted channels connected by a web to define a trough therebetween. The raceway forming member comprises a longitudinal cover element sized to span the trough at a selected upper point of said channels and having edge means adapted to abut said channels, and at least one longitudinal separator member depending from and coextensive in length with said cover element to define at least two cell raceway.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
An electrical wiring distributing floor structure comprising a metal subfloor and an overlying layer of concrete, said metal subfloor including: a distribution unit comprising at least first and second longitudinal, spaced-apart inverted channels presenting spaced crests, said channels being connected by a web positioned therebetween and joining said channels to form a trough; and a raceway forming member comprising: a cover member substantially coextensive in length with said channels and at least coextensive in width with said trough, said cover member including edge means adapted to engage said first and second channels, said cover member having a hat-shaped transverse profile, being disposed above the level of said spaced crests, and providing a housing substantially coextensive in length with said trough.
Claim 2
Dependent Claim
120 words
An electrical wiring distributing floor structure comprising a metal subfloor and an overlying layer of concrete, said metal subfloor including: a distribution unit comprising at least first and second longitudinal, spaced-apart inverted channels presenting spaced crests, said channels being connected by a web positioned therebetween and joining said channels to form a trough; and a raceway forming member comprising: a cover member substantially coextensive in length with said channels and at least coextensive in width with said trough, said cover member including edge means adapted to engage said first and second channels, said cover member having a hat-shaped transverse profile, being disposed above the level of said spaced crests, and providing a housing substantially coextensive in length with said trough.
Claim 3
Dependent Claim
46 words
The floor structure as defined in claim 1 wherein said cover member is provided with outlet openings spaced along the length thereof and wherein preset access housings are secured to the cover member in overlying relation with said access openings to provide access to said raceways.
Claim 4
Dependent Claim
38 words
The floor structure as defined in claim 1 including a hat-shaped insert residing within said trough, engaging said web and dividing said trough into said two raceways, said insert cooperating with said web to define a third raceway.
Claim 5
Dependent Claim
55 words
The floor structure as defined in claim 1 including at least one separator member substantially coextensive in length with the cover member, connected thereto and depending therefrom into said trough, said separator having a depth at least substantially the same as the depth of said trough and dividing said trough into at least two raceways.
Claim 6
Dependent Claim
23 words
The floor structure as defined in claim 4 wherein said separator member is L-shaped including a base adapted to rest upon said web.
Claim 7
Dependent Claim
104 words
A raceway forming member in cooperation with either cellular or non-cellular flooring units having first and second longitudinal, spaced-apart inverted channels presenting spaced crests, said channels being connected by a web positioned therebetween and joining said channels forming a trough, said member comprising: a cover member substantially coextensive in length with said channels and at least coextensive in width with said trough, said cover member including edge means adapted to engage said first and second channels, said cover member comprising an elongated hat-shaped member disposed above the level of said spaced crests and providing an access housing substantially coextensive in length with said trough.
Claim 8
Dependent Claim
104 words
A raceway forming member in cooperation with either cellular or non-cellular flooring units having first and second longitudinal, spaced-apart inverted channels presenting spaced crests, said channels being connected by a web positioned therebetween and joining said channels forming a trough, said member comprising: a cover member substantially coextensive in length with said channels and at least coextensive in width with said trough, said cover member including edge means adapted to engage said first and second channels, said cover member comprising an elongated hat-shaped member disposed above the level of said spaced crests and providing an access housing substantially coextensive in length with said trough.
Claim 9
Dependent Claim
42 words
The raceway forming member as defined in claim 6 wherein outlet openings are provided in said cover member and wherein preset access housings are secured to the cover member in covering relation with said outlet openings to provide access to said raceways.
Claim 10
Dependent Claim
40 words
The raceway forming member as defined in claim 6 including a hat-shaped insert residing within said trough, engaged with said web and dividing said trough into said two raceways, said insert cooperating with said web to define a third raceway.
Claim 11
Dependent Claim
56 words
The raceway forming member as defined in claim 6 including at least one separator member substantially coextensive in length with the cover member, connected thereto and depending therefrom into said trough, said separator having a depth at least substantially the same as the depth of said trough and dividing said trough into at least two raceways.
Claim 12
Dependent Claim
24 words
The raceway forming member as defined in claim 9 wherein said separator member is L-shaped including a base adapted to rest upon said web.
