Abstract

A family cycle 3, designed for one adult and two children to propel the cycle together, is controlled by the adult with separate handlebars, seats and pedals for use by children. An additional toddler seat is located in front of the adult. The adult's chain wheel A drives double chain wheel B on the inner sprocket. Children's chain wheels C & D link by chain to the outer sprocket of chain wheel B. All chain wheel sprockets are equally toothed so that the adult and children pedal at same speed. <IMAGE>

Description

THE FAMILY CYCLE The Family Cycle has been designed for one parent and to children to combine in propelling the cycle. The children have the enjoyri,ent of cycling on the road in safety, as the parent has control of the cycle. There is an additional seat for a younger child in front of the parent.
Fig 1 - is the Family Cycle.
Fig 2 - is the chain set-up for the main drive.
The parent's chainwheel (a) drives a double chainwheel (b) on the inner sprocket.
wig 3 - the children's chainwheels (c) & (d) link up by chain to the outer sprocket of chainwheel (b).
All the sprockets shown in wigs 2 & 3 are of 40 teeth so parent and children pedal at the same speed.
On the chain runs are tensioners (f) & (g) to take up any slack in the chain.
Fig 4 - on the other side of double chainwheel kb) spindle is another double chainwheel (e) with 40 tooth and 50 tooth sprockets to allow for high and low ear ratios to the rear wheel. This drives standard chain-shift gears.
