Abstract
Abstract A supporting surface provided by utilizing a plurality of individual sections which when joined will provide a planar supporting surface and which sections include formed outer skins having a plurality of supporting post sections formed integrally with the skins and extending from the upper skin surface to the lower skin surface thus providing a void between the skins which may be filled with material to provide additional strengthening for the sections. The formed sections include a stepped interlocking feature for joining the sections and the sections are designed to permit a selection of joining arrangements to provide a supporting surface of various configurations. The surfaces may include non-slip characteristics formed integrally with the sections during the molding process.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
A support structure including a plurality of individual first support sections, each such first section including: a. an upper generally planar surface; b. a lower surface spaced from said upper surface; c. side walls extending between said upper and lower surfaces; d. end walls extending between said upper and lower surfaces, said end walls, side walls, upper and lower surfaces defining a stepped portion extending entirely transversely across said section; and, e. said stepped portion of each of said end walls being respectively oppositely directed whereby next adjacent first sections may overlap upon the stepped portion; f. each of said support sections being provided with a plurality of longitudinally and transversely aligned axial columns formed between said upper and lower surfaces connecting the same and defining an axial passage therethrough; g. longitudinally extending grooves being formed in one of said surfaces and connecting the aligned axial passages on said surface; and, h. transversely extending grooves being formed in the other of said surfaces and connecting the aligned passages on said surface.
Claim 2
Dependent Claim
171 words
A support structure including a plurality of individual first support sections, each such first section including: a. an upper generally planar surface; b. a lower surface spaced from said upper surface; c. side walls extending between said upper and lower surfaces; d. end walls extending between said upper and lower surfaces, said end walls, side walls, upper and lower surfaces defining a stepped portion extending entirely transversely across said section; and, e. said stepped portion of each of said end walls being respectively oppositely directed whereby next adjacent first sections may overlap upon the stepped portion; f. each of said support sections being provided with a plurality of longitudinally and transversely aligned axial columns formed between said upper and lower surfaces connecting the same and defining an axial passage therethrough; g. longitudinally extending grooves being formed in one of said surfaces and connecting the aligned axial passages on said surface; and, h. transversely extending grooves being formed in the other of said surfaces and connecting the aligned passages on said surface.
Claim 3
Dependent Claim
48 words
The structure as set forth in claim 1 and a non-skid surface being formed on each of said surfaces between the grooves provided thereon, said non-skid surface being provided by at least longitudinally and transversely arranged abraded areas to form a pattern on said surfaces between said grooves.
Claim 4
Dependent Claim
246 words
A support structure including at least a first second and end support sections: a. said first sections including; 1. an upper generally planar surface; 2. a lower surface spaced from said upper surface; 3. side walls extending between said upper and lower surfaces; 4. end walls extending between said upper and lower surfaces, said end walls, side walls, upper and lower surfaces defining a stepped portion extending entirely transversely across said section; and, 5. said stepped portion of each of said end walls being respectively oppositely directed whereby next adjacent first sections may overlap upon the stepped portion; b. said second support sections including; 1. an upper generally planar surface; 2. a lower surface spaced from and rotated with respect to said upper surface; 3. end walls and side walls extending between said upper and lower surfaces; 4. said upper and lower surfaces defining pairs of stepped portions at the ends of said upper surface and lower surface, each pair being oppositely directed whereby adjacent first sections may overlap therewith; c. said first sections being of a predetermined width and length; d. said upper and lower surfaces of said second sections having lengths equal to the width of said first section, and having widths less than the width of said first section; and, e. said end sections having a length equal to the width of said first sections and having a width equal to one-half the difference between the widths of said first and second sections.
Claim 5
Dependent Claim
246 words
A support structure including at least a first second and end support sections: a. said first sections including; 1. an upper generally planar surface; 2. a lower surface spaced from said upper surface; 3. side walls extending between said upper and lower surfaces; 4. end walls extending between said upper and lower surfaces, said end walls, side walls, upper and lower surfaces defining a stepped portion extending entirely transversely across said section; and, 5. said stepped portion of each of said end walls being respectively oppositely directed whereby next adjacent first sections may overlap upon the stepped portion; b. said second support sections including; 1. an upper generally planar surface; 2. a lower surface spaced from and rotated with respect to said upper surface; 3. end walls and side walls extending between said upper and lower surfaces; 4. said upper and lower surfaces defining pairs of stepped portions at the ends of said upper surface and lower surface, each pair being oppositely directed whereby adjacent first sections may overlap therewith; c. said first sections being of a predetermined width and length; d. said upper and lower surfaces of said second sections having lengths equal to the width of said first section, and having widths less than the width of said first section; and, e. said end sections having a length equal to the width of said first sections and having a width equal to one-half the difference between the widths of said first and second sections.
Claim 6
Dependent Claim
81 words
The structure set forth in claim 3 and each of said first, second and end sections including: a. a plurality of longitudinally extending grooves on one side thereof; b. a plurality of transversely extending grooves on the other side thereof; c. and a non-skid surface formed on each of said surfaces between the grooves provided thereon, said non-skid surface being formed by providing at least longitudinally and transversely arranged abraded areas to form a pattern on said surface between said grooves.
