Abstract
Abstract A support member or tie bar for supporting and connecting T-shaped flooring members. The support member has an integral one-piece body with an elongated base and a number of support structures or bridges extending upwardly from the base. Each support structure has a relatively wide bottom and a narrow upper section. The upper section has a ledge formed on each transverse side thereof for supporting an edge of the horizontal portion of the T-shaped member. The base and the adjacent transverse sides of each pair of adjacent bottoms form a groove for receiving and supporting a bottom edge of the flooring member. Each support structure and the underlying base forms a trapezoid shape as seen in longitudinal cross-section and the center of the trapezoid is hollow. Each ledge is located a short distance below the top of the support structure. A transversely extending horizontal lip is formed on each transverse side of each support structure at the bottom of the support structure but spaced above the top surface of the base.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
98 words
A support member for supporting and connecting structural members such as flooring members comprising an integral one-piece body having an elongated base and a plurality of supporting structures extending upwardly from said base, each support structure having a relatively wide bottom and a narrow upper section, said upper section having support means formed on each transverse side thereof for supporting an upper, side edge of a structural member, wherein said base and the transverse sides of adjacent bottoms of said support structures form a groove for receiving and supporting a bottom edge of one of the structural members.
Claim 2
Dependent Claim
98 words
A support member for supporting and connecting structural members such as flooring members comprising an integral one-piece body having an elongated base and a plurality of supporting structures extending upwardly from said base, each support structure having a relatively wide bottom and a narrow upper section, said upper section having support means formed on each transverse side thereof for supporting an upper, side edge of a structural member, wherein said base and the transverse sides of adjacent bottoms of said support structures form a groove for receiving and supporting a bottom edge of one of the structural members.

Claim 4
Dependent Claim
15 words
A support member according to claim 1 wherein said support member consists essentially of polyethylene.
Claim 5
Dependent Claim
34 words
A support member according to claim 1 wherein the support means formed on each transverse side is a ledge providing a horizontal surface spaced a short distance below the top of the support structure.
Claim 6
Dependent Claim
42 words
A support member according to claim 1 wherein each support structure has a transversely extending horizontal lip formed on each transverse side thereof, said lip being provided on the bottom of the support structure but spaced above the top of said base.
Claim 7
Dependent Claim
17 words
A support member according to claim 1 wherein said support member is made of glass and polypropylene.
Claim 8
Dependent Claim

Dependent Claim
20 words
A support member according to claim 1 wherein said support member is made of approximately 20% glass and a polyolefin.
Claim 10
Dependent Claim
56 words
A support member according to claim 1 or 4 wherein said support member has a connecting device at each end thereof for connecting the support member to another similar support member so that the combined support members are arranged in longitudinal alignment, each connecting device being constructed to form one half of a further support structure.
Claim 11
Dependent Claim
32 words
A support member according to claim 1 wherein each support structure and the adjoining underlying base forms a trapezoid shape as seen in longitudinal cross-section, the center of said trapezoid being hollow.
Claim 12
Dependent Claim
34 words
