Abstract

A means of powering a bicycle through a reciprocating action of pedal crank arms by means of a cable 14, pulleys and a pulley mounting unit 11, to synchronize the cranks mounted on an axle 13 by means of respective ratchet mechanisms 12.

Description

<p>I</p>
<p>Bicycle ratcnet crank.</p>
<p>This invention relates to a device which provides a means of powering a bicycle by introducing a ratcoet mechanism between the crank and the drive axieproducing a reciprocating instead of a rotating pe'al action.</p>
<p>The invention will now be described solely by way of example and with referexence to the accompanying drawings in which Drawing page I of 8 snows a side view of the crank with cornonent parts.</p>
<p>Drawing page 2 of 8 shows a clan view of the cran'< wiLi componenr:arts.</p>
<p>Drawing pae 5 of 8 shows a nan an] side view of the pulley nointing unit.</p>
<p>Drawing page 4 of 8 shows a plan and sue view of an alternative pulley mounting unit.</p>
<p>Drawing page 5 of 8 snows a side view of the cranks mounted on the axle the main drive gear, the oicycle cnassis, and the pulley mounting unit.</p>
<p>The drawing shows one ratchet pawl with positions for multipile nawls, the number dependent upon the intended use.</p>
<p>Drawing page 6 of 8 shows a plan view of the cranKs on tAe axle, toe main drive gear, the bicycle chassis and the pulley mounting unit.</p>
<p>Drawing page 7 of 8 shows a side view of the pulley mounting unit in a alternative arrangement. Arrangement of the pulley mounting unit on the bicycle chassis is dependent on the configuration of the chassis and is not confined to toe arrangement Dresented in the drawings.</p>
<p>Drawing page 8 of 8 is a list of toe parts and numbers in toe drawings.</p>
<p>1here are a number of configurations that can be used, some of which will be described: I) Referin to drawings age 5 6,this shows the pulley mounting unit in a position riorizontal to the ground, the crans fitted to b e axle with the cable routeing over four pulleys and anchored on each crank.</p>
<p>Movement on one crank will be transmitted througri tne cable via the pulleys to toe other crank. In tois arrangement the cran<s are permanently synchronized.</p>
<p>2) Refering to drawings page 4 & 7 toe pulley mounting unit is in a position perpendicular to the ground with toe cable routeing around two guide pulleys aod a tension pulley and anchored on both cranks. In this arrangement both cranks would assume the same attitude at rest. Depressing one pedal results in the slack held in tension by the spring loaded nulley being taken up and synchronization of the cranks occurs.</p>
<p>3) Refering to drawing 6 the sorings located between the pulley mounting unit and the crank would return the cranks to their starting position.</p>
<p>In this arrane ment the stops are essential.</p>
<p>4) The final arrangement to be described is, fit tce cranks with the ratchet and depend on secure fittings between the cyclists shoe and the pedal to return the crank to tne desired position.</p>

Claims (1)

  1. <p>Claims.</p>
    <p>I) A means of powerinc a bicycle by introducing a ratchet mechanism between the crank and the drive axle that aLlows the cyclists feet to rlefthe a reciprocal action in contrast to rotational motion.</p>
    <p>2) A means of powering a bicycle according to claim I in which te cranks are returned to a starting position by means of a torsion spring.</p>
    <p>3) A meau of powering a bicycle as in cLaim I comprising cable, pulleys and a pulley mounting unit, also means for attaching the unit to a bicycle.</p>
    <p>4) A means of powering a bicycle according to claim I and claim 3 in which the cable is routeing round Lae pulley-s and anchored on both the cranks.</p>
    <p>5) A means of powering a oicycle as in claim I claim 3 and claim 4 where adjustable tension is applied to trie cable ensuring that the cable remains taut during operation.</p>
    <p>6) A means of powering a bicycle according to any of the rrecedin claims in which tne cranks are prevented from excessive -ovement by a1justacle stoi,s.</p>
