Abstract
The present invention provides an adjustable ladder and scaffolding system wherein a scaffolding structure provides a support to which is attached a frame. The frame includes a pair of ladder clamps that enable the frame to be connected to the spaced apart risers of a ladder that is to be supported. The frame includes left and right plates and a base opposite the ladder clamps. Adjustable connections are provided between the left and right plates and the base so that the distance between the base and the clamps can be varied, thus enabling the ladder to assume a diagonally extending orientation relative to horizontal. The frame is adjustable so that each frame attached to the ladder shortens the distance between the ladder and the scaffolding structure as the elevation is increased.
