The challenge

Artificial leg height adjusterAn elderly client needs to be able to adjust the height of his artificial limb to compensate for limited hip movement following a fall.  A sprung pin operates from a button on the hip via a bicycle gear cable.  It retracts to allow the leg to lower by 20mm when the client’s weight is applied.  A spring within the aluminium tubing allows the leg to extend as the client’s weight is removed with the pin retracted. Sponge tubing covers the unit.

The client can now negotiate differing pavement slopes and angles.  He is no longer constrained in where he can shop in his nearby town and can walk on uneven terrain in his extensive garden.
