Abstract:
1. A detectably joinable bicycle frame comprising: A. a seat tube having a proximal end and a distal end, the distal end terminating at a distal bracket, B. a forward assembly supported by a head tube and wheel forks and a forward wheel, the forward assembly containing forward and rearward sections of a forward assembly proximal tube and a forward assembly distal tube, the forward assembly tubes having longitudinal axes and forward and rearward terminal ends, the forward assembly tubes being split, each forward assembly tube having substantially uniform cross sections of any shape, each split dividing each forward assembly tube into the forward and rearward sections, the forward and rearward sections of not necessarily equal lengths, each forward section of each split forward assembly proximal tube and split forward assembly distal tube being formed of integral pieces, each rearward section of each split forward assembly proximal tube and forward assembly distal tube being formed of integral pieces, the forward sections of each split forward assembly proximal tube and distal tube each having a forward end and a rearward end, the forward ends of the forward sections terminating either near one another or together at the head tube, the rearward end of the forward assembly proximal tube terminating generally at the seat tube proximal end, the rearward end of the forward assembly distal tube intersecting and terminating at the seat tube distal end at the distal bracket, C. a rear assembly supported by a rear wheel and containing paired rear assembly proximal tubes and paired rear assembly distal tubes, each rear assembly tube having substantially uniform cross sections of any shape, each tube having a forward terminal end and a rearward terminal end, the rear assembly tubes meeting at their rearward terminal ends, the forward terminal end of each rear assembly proximal tube terminating on the seat tube at or near the point where the rearward section of the forward assembly proximal tube intersects the seat tube, the forward terminal end of each rear assembly distal tube terminating at the distal bracket, D. a first coupling assembly for detachably joining the forward and rearward sections of the forward assembly proximal tube, a second coupling assembly of like structure as the first coupling assembly for detachably joining the forward and rearward sections of the forward assembly distal tube, the first coupling assembly and the second coupling assembly each comprising a first plate member having a first plate member face and a first plate member rear and a second plate member having a second plate member face and a second plate member rear, each plate member having a predetermined shape and having two ends with at least one opening in one end and at least one opening in the other end, the openings dimensioned to accept mounting bolts, the openings having no shoulder portions extending from and integral to the plate members, wherein in the first coupling assembly the first plate member rear is fastened by a fastening means to the rearward end of the forward section of the split forward assembly proximal tube, the second plate member rear is fastened by a fastening means to the forward end of the rearward section of the split forward assembly proximal tube, the first and second plate members are fastened face to face by a fastening means, the fastening means being other than a clamp, the plate members not hingedly attached to each other, the plate members completely seating off the tubes, and wherein in the second coupling assembly the first plate rear is fastened by a fastening means to the rearward end of the forward section of the split forward assembly distal tube, the second plate rear is fastened by a fastening means to the forward end of the rearward section of the split forward assembly distal tube, and the first and second plate members are fastened face to face by a fastening means, the fastening means being other than a clamp, the plate members not hingedly attached to each other, the plate members completely seating off the tubes.
