Patent ID: 7789199

Claim:
An attachment apparatus for a ladder having a plurality of rungs extending between a pair of elongated rails, comprising: a longitudinal member having a first end and a second end opposite the first end, the longitudinal member adapted to be coupled to one of the plurality of rungs; first and second pivotal couplers, each pivotal coupler having two planar members, wherein the first pivotal coupler abuts the first end of the longitudinal member and the second pivotal coupler abuts the second end of the longitudinal member; and first and second support modules, each support module having an elongated support member and a support arm projecting outwardly therefrom in a first direction, the first support module being hingeably coupled to the two planar members of the first pivotal coupler and the second support module being hingeably coupled to the two planar members of the second pivotal coupler, each support arm having an end thereof defining a surface, the surface being at a fixed position relative to its respective elongated support member, the surface being operable to rest against a vertical support structure when the first and second support modules are located in a first position, the first position defined by a longitudinal axis of the elongated support members being substantially parallel with a longitudinal axis of the main support, and the surface of each support arm being operable to rest against a vertical support structure when the first and second support modules are located in a second position, the second position defined by the longitudinal axis of the elongated support members being substantially orthogonal with the longitudinal axis of the main support.
