Abstract
Abstract A connector fixture for joining a first structural member to a second structural member. The second structural member includes a central bore and a pair of lug receiving apertures disposed at a predetermined distance on opposite sides of the central bore. The first structural member includes a central bore adapted to register with the central bore of the second structural member and in addition has a pair of outwardly extending lugs which register with and are received in the lug receiving apertures in the second structural member, thereby properly positioning the first and second structural members relative to each other. A connector, such as a bolt and nut, is then inserted through the central bore of the first and second structural members to clamp the members together. The lug is circular and comprises one or more raised segments, wherein the outer periphery of the raised segment is dimensioned to fit closely adjacent to at least a portion of the inner surface of one of the lug receiving apertures in said second structural member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
191 words
A connector fixture comprising: a first structural member having a central bore formed therethrough and a pair of lugs formed thereon, said lugs being formed on opposite sides of said central bore; a second structural member having a central bore in register with said central bore of said first structural member and having a pair of lug receiving apertures formed therethrough which register with and receive said lugs of said first structural member therein; and a connector inserted through said registering central bores of said first and second structural members clamping said first structural member to said second structural member, wherein each of said lugs comprises a segment having a generally-flat, thin, first portion generally parallel to the surface of the first structural member and having an exposed edge surface generally normal to the surface of the first structural member, and a second portion between the first structural member and the first portion and supporting the first portion in a centilever-like fashion above and spaced from the surface of the first structural member, said segment being fitted within a corresponding one of said lug receiving apertures in said second structural member.
Claim 2
Dependent Claim
191 words
A connector fixture comprising: a first structural member having a central bore formed therethrough and a pair of lugs formed thereon, said lugs being formed on opposite sides of said central bore; a second structural member having a central bore in register with said central bore of said first structural member and having a pair of lug receiving apertures formed therethrough which register with and receive said lugs of said first structural member therein; and a connector inserted through said registering central bores of said first and second structural members clamping said first structural member to said second structural member, wherein each of said lugs comprises a segment having a generally-flat, thin, first portion generally parallel to the surface of the first structural member and having an exposed edge surface generally normal to the surface of the first structural member, and a second portion between the first structural member and the first portion and supporting the first portion in a centilever-like fashion above and spaced from the surface of the first structural member, said segment being fitted within a corresponding one of said lug receiving apertures in said second structural member.
Claim 3
Dependent Claim
34 words
The connector fixture as defined in claim 1 wherein said segment is formed as a circle segment, and wherein said lug receiving aperture is round and has substantially the same diameter as said segment.
Claim 4
Dependent Claim
17 words
The connector fixture as defined in claim 2 wherein the outer periphery of said segment is semi-cylindrical.
Claim 5
Dependent Claim
193 words
A connector fixture comprising: a first structural member having a central bore formed therethrough and a pair of lugs formed thereon, said lugs being formed on opposite sides of said central bore; a second structural member having a central bore in register with said central bore of said first structural member and having a pair of lug receiving apertures formed therethrough which register with and receive said lugs of said first structural member therein; and a connector inserted through said registering central bores of said first and second structural members clamping said first structural member to said second structural member, wherein each of said lugs comprises a pair of back-to-back segments having generally-flat, thin, first portions generally parallel to the surface of the first structural member and having exposed edge surfaces generally normal to the surface of the first structural member, and second portions between the first structural member and the first portions and supporting the first portions in a cantilever-like fashion above and spaced from the surface of the first structural member, said pair of segments being fitted within a corresponding one of said lug receiving apertures in said second structural member.
Claim 6
Dependent Claim
193 words
A connector fixture comprising: a first structural member having a central bore formed therethrough and a pair of lugs formed thereon, said lugs being formed on opposite sides of said central bore; a second structural member having a central bore in register with said central bore of said first structural member and having a pair of lug receiving apertures formed therethrough which register with and receive said lugs of said first structural member therein; and a connector inserted through said registering central bores of said first and second structural members clamping said first structural member to said second structural member, wherein each of said lugs comprises a pair of back-to-back segments having generally-flat, thin, first portions generally parallel to the surface of the first structural member and having exposed edge surfaces generally normal to the surface of the first structural member, and second portions between the first structural member and the first portions and supporting the first portions in a cantilever-like fashion above and spaced from the surface of the first structural member, said pair of segments being fitted within a corresponding one of said lug receiving apertures in said second structural member.
Claim 7
Dependent Claim
34 words
The connector fixture as defined in claim 4 wherein said segments are formed as back-to-back circle segments, and wherein said lug receiving aperture is round and has substantially the same diameter as said segments.
Claim 8
Dependent Claim
18 words
The connector fixture as defined in claim 4 wherein the outer peripheries of said back-to-back segments are semi-cylindrical.
