Patent ID: 7967735

Claim:
An exercise device comprising: a resilient force member arranged to be acted on by a user and provide resistance against movement by a user over an operative range; and an indicator device comprising an audible signal producing member having first and second physical configurations, and which is acted on by the resilient force member, in use, to change the physical configuration of the audible signal producing member, wherein the change in physical configuration creates an audible signal, and the audible signal producing member having a bistable stress-strain state, and the first and second physical configurations comprising first and second stable stress strain states of the audible signal producing member; wherein the audible signal producing member comprises a deflection member, and the resilient force member acts on the deflection member to deflect the deflection member; and wherein the deflection member comprises a plate formed to so as to have a concavity or other structure which is invertable when the deflection plate is bent to define the first and second physical configurations.
