Work control apparatus in an exerciser

摘要

A work control apparatus in a bicycle exerciser having a driven member rotatively mounted on an exerciser frame. The work control apparatus includes a rotatively mounted knob connected to a brake for the driven member for selectively determining the braking pressure exerted on the driven member. The brake includes a lever pivotally attached to the exerciser frame and having a brake roller at one end engaging the exerciser driven member and the knob is adjustably connected to the other end of the brake lever and is rotatable to exert a predetermined braking pressure between the roller and driven member. The knob is drivingly connected to a rotatively mounted indicator wheel for rotating the wheel an angular distance less than the corresponding angular distance of the knob upon rotation of the knob incident to adjusting the braking pressure. The drive connection between the knob and the indicator wheel includes an idler wheel connected to the knob and the indicator wheel by endless flexible elements and a cover having a window is mounted above the indicator wheel to selectively reveal numerical indicia on the indicator wheel as the knob is rotated.
