Abstract

Abstract This invention is an attachment apparatus operable to interconnect two bicycle members in a side-by-side relationship. The attachment apparatus includes a main support coupling means to interconnect the bicycle members and a steering coordinator means to interconnect the steering mechanism on each bicycle member. The main support coupling means is connected to each steering post housing on each bicycle member to permit a constant distance between each bicycle member while permitting relative rotation therebetween. The steering coordinator means interconnects the turning forks on each bicycle member to assure joint and same turning of each front wheel member when steering the bicycle members.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 177 words
An attachment apparatus for interconnecting side-by-side bicycle members, comprising: (a) a main support coupling means to interconnect said bicycle members, including a horizontal connector assembly and an inclined connector assembly connected between said horizontal connector assembly and respective ones of said bicycle members; (b) a steering coordinator means connected between a steering mechanism on each of said bicycle members to achieve conjoint movement of front wheel members on each of said bicycle members; (c) said horizontal connector assembly includes a steering post connector assembly mounted on each of said bicycle members and interconnected to each other by a connector rod assembly; (d) said connector rod assembly includes an outer connector tube member formed in two connector tube sections, each secured to respective ones of said steering post connector assemblies with said connector tube sections rotatable relative to each other and allows independent rotational movement of said bicycle members; and (e) said connector rod assembly includes an inner main rod assembly rotatably connected to said outer connector tube member to maintain the spaced relationship of said bicycle members.
Claim 2
Dependent Claim 177 words

Claim 3
Dependent Claim 102 words
The attachment apparatus as described in claim 1, wherein: (a) said steering coordinator means includes an anchor plate member secured to each of said steering mechanisms, a steering rod assembly connected between said anchor plate members and an adjustment connector assembly mounted on said steering rod assembly; (b) said adjustment connector assembly rotatable to achieve a parallel relationship of said front wheel members on said bicycle member; and (c) said anchor plate members each having an elongated, flexible main body portion with a hole in the outer ends thereof for connection to said steering rod assembly and permits vertical, flexible movement therebetween.
Claim 4
Dependent Claim 228 words
An attachment apparatus for interconnecting side-by-side bicycle members, comprising: (a) a main support coupling means to interconnect said bicycle members, including a horizontal connector assembly and an inclined connector assembly connected between said horizontal connector assembly and respective ones of said bicycle members; (b) a steering coordinator means connected between a steering mechanism on each of said bicycle members to achieve conjoint movement of front wheel members on each of said bicycle members; (c) said horizontal connector assembly includes a steering post connector assembly mounted on each of said bicycle members and interconnected to each other by a connector rod assembly; (d) said connector rod assembly includes an outer connector tube member which allows independence rotational movement of said bicycle members; (e) said steering post connector assembly includes a connector member mounted against each respective steering housing of each of said bicycle members by clamp members; (f) each of said connector members having a laterally extended horizontal tube portion for connection to said connector rod assembly; (g) said connector rod assembly includes said outer connector tube member secured at outer ends to respective ones of said horizontal tube portions and an inner main rod assembly connected to said outer connector tube member to maintain the spaced relationship of said bicycle members; and (h) said outer connector tube member constructed in half sections to permit relative rotational movement therebetween.
Claim 5
Dependent Claim 228 words
An attachment apparatus for interconnecting side-by-side bicycle members, comprising: (a) a main support coupling means to interconnect said bicycle members, including a horizontal connector assembly and an inclined connector assembly connected between said horizontal connector assembly and respective ones of said bicycle members; (b) a steering coordinator means connected between a steering mechanism on each of said bicycle members to achieve conjoint movement of front wheel members on each of said bicycle members; (c) said horizontal connector assembly includes a steering post connector assembly mounted on each of said bicycle members and interconnected to each other by a connector rod assembly; (d) said connector rod assembly includes an outer connector tube member which allows independence rotational movement of said bicycle members; (e) said steering post connector assembly includes a connector member mounted against each respective steering housing of each of said bicycle members by clamp members; (f) each of said connector members having a laterally extended horizontal tube portion for connection to said connector rod assembly; (g) said connector rod assembly includes said outer connector tube member secured at outer ends to respective ones of said horizontal tube portions and an inner main rod assembly connected to said outer connector tube member to maintain the spaced relationship of said bicycle members; and (h) said outer connector tube member constructed in half sections to permit relative rotational movement therebetween.
Claim 6
Dependent Claim 74 words
The attachment apparatus as described in claim 3, wherein: (a) said inner main rod assembly includes a rod assembly having a connector assembly at each outer end thereof; and (b) said rod assembly extends the length of said outer connector tube member and said connector assembly abuts each outer end of said outer connector tube member to hold said half sections in abutting relationship but permitting relative rotation of said inner main rod assembly.
Claim 7
Dependent Claim 39 words
The attachment apparatus as described in claim 4, wherein: (a) said connector rod assembly includes an intermediate lubrication tube mounted between said outer connector member and said inner main rod assembly to provide lubrication for relative rotational movement therebetween.
