Abstract

Abstract An arrangement for coupling a seat to the frame of a recumbent bicycle includes brackets on the seat for engaging a frame member of the bicycle, openings in the frame member and the brackets for alignment and locking pins for insertion into the aligned openings to attach the seat to the frame. A steering arrangement for the recumbent bicycle includes a fork for supporting the steerable front wheel of the bicycle, a fork tube on the frame for pivotally supporting the fork from the frame, a pair of steering arms on the fork, a handlebar pivotally mounted on the frame generally beneath the seat, and cables coupling the steering arms to respective sides of the handlebar.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 180 words
A steering mechanism for a cycle having a frame, the steering mechanism comprising a fork for supporting a steerable wheel, means for pivotally mounting the fork on the frame, means providing a pair of generally oppositely projecting steering arms on the fork, a handlebar steering control providing a pair of generally oppositely projecting steering arms, means for mounting the steering control pivotally from the frame, and cables coupling respective fork steering arms to respective steering control steering arms whereby manipulation of the steering control effects steering of the steerable wheel, the means for pivotally mounting the steering control including means providing two facing, load-bearing surfaces on the frame, a block for insertion between the facing surfaces, a thrust bearing for insertion between each of the load-bearing surfaces and a respective adjacent surface of the block, means providing aligned openings in the load-bearing surface-providing means, the block and the thrust bearings, a pivot pin for insertion into the aligned openings to mount the block pivotally upon the frame, and means for mounting the handlebar steering control to project from the block.
Claim 2
Dependent Claim 180 words
A steering mechanism for a cycle having a frame, the steering mechanism comprising a fork for supporting a steerable wheel, means for pivotally mounting the fork on the frame, means providing a pair of generally oppositely projecting steering arms on the fork, a handlebar steering control providing a pair of generally oppositely projecting steering arms, means for mounting the steering control pivotally from the frame, and cables coupling respective fork steering arms to respective steering control steering arms whereby manipulation of the steering control effects steering of the steerable wheel, the means for pivotally mounting the steering control including means providing two facing, load-bearing surfaces on the frame, a block for insertion between the facing surfaces, a thrust bearing for insertion between each of the load-bearing surfaces and a respective adjacent surface of the block, means providing aligned openings in the load-bearing surface-providing means, the block and the thrust bearings, a pivot pin for insertion into the aligned openings to mount the block pivotally upon the frame, and means for mounting the handlebar steering control to project from the block.
Claim 3
Dependent Claim 29 words
The apparatus of claim 1 wherein the thrust bearings comprise roller thrust bearings for insertion between each of the load-bearing surfaces and a respective adjacent surface of the block.
Claim 4
Dependent Claim 12 words

Claim 5
Dependent Claim 13 words
The apparatus of claim 1 wherein the pivot pin comprises a shoulder bolt.
Claim 6
Dependent Claim 19 words
The mechanism of claim 1 and further comprising a turnbuckle for adjusting the tension of one of said cables.
Claim 7
Dependent Claim 19 words
The apparatus of claim 1 and further comprising roller bearings for insertion between the pivot pin and the block.
