Abstract
A scaffold construction includes a fixed leg portion and an adjustable platform portion with a spring loaded pin connection operatively connecting between the two to selectively lock the leg and the platform in the required relationship. The pin is mounted on one end of a leaf spring which in turn is secured to the platform and engages any one of a plurality of apertures in the leg portion. A gravity operated locking device normally prevents inadvertent disengagement of the pin from the leg unless it is moved upwardly manually thus preventing accidental and inadvertent collapse of the platform relative to the leg.
