Abstract
A stilt includes a tube having a number of holes, and a sleeve is slidably engaged on the tube. The sleeve includes an orifice and a depression formed in a wall member for slidably receiving a catch and a spring. A lever is pivotally coupled to the sleeve and has one end engaged with the catch for moving the catch. A foot support is pivotally coupled to the sleeve. The spring biases the lever in order to engage the catch with either of the holes of the tube such that the sleeve may be adjusted along the tube when the catch is disengaged from the tube.
