ABSTRACT:
A ladder and platform assembly is described for stabily and releasably securing a ladder to a utility pole or the like. The ladder is attched at one end to a platform and includes a pair of generally parallel, spaced apart legs and a plurality of steps disposed between and interconnected between the legs. The platform includes a latch assembly for stabilizing the platform when the platform is disposed to rest against the pole, which has a given configuration. The platform has an opening of a configuration similar to the given configuration for receiving the pole. The latch assembly includes a latch pivotally mounted on the platform to move between a first, closed position wherein the latch retains the pole within the opening and a second, closed position wherein the latch permits the pole to be received within or removed from the opening. The latch has an extended portion. A spring is attached to the latch for normally biasing the latch to the second, open position. A self locking detent is disposed for engaging the extended position of the latch as it moves to the second, closed position and retaining the latch in a locked relationship therewith in the second, closed position. An actuable mechanisim is provided for releasing the detente from the locked relationship with the latch and permitting the latch to return to its first, open position under the influence of the biasing spring.
