A lightweight, multifunction scaffold comprises first and second ladder frames, and an adjustable height platform configured to be supported between the first and second ladder frames at a user selected height in an adjustment range. The adjustable height platform comprises a pair of spaced-apart side rails extending between the ladder frames and a deck supported on opposing sides by the side rails. The deck includes at least one recess in a top surface of the deck adjacent each of the opposing sides of the deck. The scaffold further includes at least one latch rotatably mounted to each side rail and including a catch element for engagement with the recess in the top surface of the deck to secure the deck on the side rails. The latch is movable between a disengaged position allowing the deck to be installed or removed from the side rials and an engaged position in which the catch element extends over a top surface of the deck and engages with a respective one of the recesses in the deck so that the catch element is flush with or below the surface of the deck.

A lightweight, multi-function scaffold includes an adjustable height platform that slidably mounts between two ladder frames. The side rails of the platform are reversible so that they can be mounted between the ladder frames in either a first orientation or in a second orientation. In the first orientation, the adjustable height platform is vertically movable between a first threshold and a maximum height. In the second orientation, the adjustable height platform is vertically movable between a second threshold and a minimum height. The ranges of movement in the first and second orientations may overlap.

The claimed invention comprises a tool shelf for a multi-function scaffold comprising two spaced apart ladder frames supporting a platform and a guard rail mounted to the platform. The tool shelf is specially designed to mount to either the ladder frame, or to the guard rail system. When the platform is adjusted to the maximum height, the worker can 5 mount the guard rail system so that the items placed on the tool shelf will be within reach without bending over. When the platform is lowered, the tool shelf can be mounted to the ladder frame.

A utility scaffold is designed to be repeatedly broken down into straighter components to reduce the space requirement for storage and shipment. The scaffold has first and second ladder frames, each comprising a plurality of vertical supports, a plurality of horizontal supports, and a plurality of releasable connections. The horizontal supports are releasably connected to the vertical supports by the releasable connections to form a rigid ladder frame structure. The releasable connections include a male wedge protrusion and a female receiver configured to receive the male wedge protrusion. The female receiver has a passage therethrough, with the passage having a tapered interior surface. The male wedge protrusion and the tapered interior surface are configured to abut when the vertical support and the horizontal support are mounted together via the releasable connection. A fastener is optionally used to secure the releasable connection.
