RELEASABLY SECURE LADDER PLATFORM

摘要

A transport assembly for transporting an object axially along a rail of a ladder. The assembly comprises a platform for supporting the object at a selected axial position. A coupling mechanism is employed to slidably connect the platform to the rail. The coupling mechanism includes a locking mechanism and a connector for connecting the coupling mechanism to the platform. Axial displacement of the object along the rail is such that the locking mechanism permits relative axial displacement of the assembly with respect to the rail in a first direction, and inhibits the relative axial displacement in a second direction opposite to the first direction.
