Abstract
A stirrup extension bar is slidably received in an elongated tubular channel equipped at its mouth with a brake pad, and the innermost end of the extension bar is equipped with a brake pad. If the coefficient of friction between the pads and interior channel walls is greater than about 0.9, the horizontal frictional forces tending to hold the bar in place are sufficiently greater than the force tending to unseat the bar, so that the bar remains locked in place. When the stirrup assembly held by the outer end of the extension bar is raised, the brake pads release and the extension bar may be adjusted horizontally. Normal use forces apply the locking force after adjustment.
