Abstract
Abstract A portable platform is formed of a plurality of elongated floor support members interconnected longitudinally and spaced apart laterally, the support members having a plurality of longitudinally spaced cross members, the confronting cross members being secured in alignment by interengaging coupling members and the laterally spaced floor support members being secured against lateral displacement by a plurality of elongated locking members interengaging adjacent pairs of support members. A plurality of elongated floor members are supported on the foregoing assembly and are secured together releasably along their longitudinal edges. The perimeter of the assembly of floor members is secured against vertical displacement relative to the underlying support assembly by means of a plurality of perimeter floor hold-down members which are secured removably against vertical and longitudinal displacement by a plurality of perimeter floor hold-down support members removably connected to the outer ends of the support members and outwardly extending associated cross members.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
178 words
A portable platform, comprising: (a) a plurality of elongated floor support members spaced apart laterally to form outer margin and intermediate floor supports, (b) each floor support member having a plurality of longitudinally spaced pairs of axially aligned cross members extending laterally in opposite directions, the confronting pairs of cross members of adjacent support members being in axial alignment, (c) a plurality of elongated coupling members each removably connected at its opposite ends to a confronting pair of cross members, (d) a plurality of elongated locking members each removably interengaging an adjacent pair of support members in between adjacent coupling members for securing said support members against lateral displacement, (e) a plurality of elongated floor members overlying the assembly of support members, cross members, coupling members and locking members and releasably secured together at their longitudinal edges, and (f) a plurality of perimeter floor confining members removably connected to the outer ends of the floor support members and outwardly extending perimeter cross members for confining the floor members against horizontal displacement relative to the underlying floor support assembly.
Claim 2
Dependent Claim
178 words
A portable platform, comprising: (a) a plurality of elongated floor support members spaced apart laterally to form outer margin and intermediate floor supports, (b) each floor support member having a plurality of longitudinally spaced pairs of axially aligned cross members extending laterally in opposite directions, the confronting pairs of cross members of adjacent support members being in axial alignment, (c) a plurality of elongated coupling members each removably connected at its opposite ends to a confronting pair of cross members, (d) a plurality of elongated locking members each removably interengaging an adjacent pair of support members in between adjacent coupling members for securing said support members against lateral displacement, (e) a plurality of elongated floor members overlying the assembly of support members, cross members, coupling members and locking members and releasably secured together at their longitudinal edges, and (f) a plurality of perimeter floor confining members removably connected to the outer ends of the floor support members and outwardly extending perimeter cross members for confining the floor members against horizontal displacement relative to the underlying floor support assembly.
Claim 3
Dependent Claim
109 words
The portable platform of claim 1 wherein the floor confining members include floor hold-down members overlying the perimeter of the floor members to prevent upward displacement of the floor members relative to the underlying floor support assembly, the floor hold-down members comprising hook members supported by and overlying the perimeter of the floor members, and a plurality of elongated angle iron members extending along the perimeter of the floor members and each having an outwardly and upwardly projecting tab on each end, at least some of the hook members removably receiving one end of an angle iron member with the associated tab confined removably by one of the hooks.
Claim 4
Dependent Claim
46 words
The portable platform of claim 2 wherein each perimeter floor confining member comprises a hollow tube on said outer ends of the floor support members and outwardly extending perimeter cross members and mounting a pair of spaced hooks configured to removably between the pair of hooks.
Claim 5
Dependent Claim
26 words
The portable platform of claim 1 wherein each coupling member is a hollow tube freely receiving in its opposite ends a confronting pair of cross members.
Claim 6
Dependent Claim
36 words
The portable platform of claim 1 wherein each locking member has a pair of longitudinally spaced notches configured to removably receive therein an adjacent pair of support members for securing said support members against lateral displacement.
Claim 7
Dependent Claim
55 words
The portable platform of claim 1 wherein each locking member comprises a central elongated hollow tube section and a pair of hollow tube end sections spaced outwardly of the central section and secured thereto by an interconnecting strap, the strap and space between the tube sections defining a notch removably receiving a support member therein.
Claim 8
Dependent Claim
40 words
The portable platform of claim 1 including an upwardly extending wall supporting post on each floor confining member, and a plurality of elongated wall members each mounted removably at its opposite ends on an adjacent pair of wall supporting posts.
Claim 9
Dependent Claim
29 words
The portable platform of claim 7 wherein each wall member has a guide member at each end configured to removably engage an adjacent pair of said wall supporting posts.
Claim 10
Dependent Claim
37 words
The portable platform of claim 1 including a fence support member on each floor confining member, and a plurality of fence members each mounted removably at its opposite ends on an adjacent pair of fence support members.
Claim 11
Dependent Claim
80 words
In a portable platform having a plurality of elongated floor support members spaced apart laterally to form outer margin and intermediate floor supports, a plurality of elongated locking members spaced apart longitudinally of and spanning adjacent floor support members for securing said floor support members against lateral displacement, each locking member having a pair of longitudinally spaced notches configured to removably receive therein an adjacent pair of said floor support members for securing said floor support members against lateral displacement.
Claim 12
Dependent Claim
80 words
In a portable platform having a plurality of elongated floor support members spaced apart laterally to form outer margin and intermediate floor supports, a plurality of elongated locking members spaced apart longitudinally of and spanning adjacent floor support members for securing said floor support members against lateral displacement, each locking member having a pair of longitudinally spaced notches configured to removably receive therein an adjacent pair of said floor support members for securing said floor support members against lateral displacement.
Claim 13
Dependent Claim
55 words
The portable platform of claim 10 wherein each locking member comprises a central elongated hollow tube section and a pair of hollow tube end sections spaced outwardly from the central section and secured thereto by an interconnecting strap, the strap and space between the tube sections defining a notch removably receiving a support member therein.
