32, each having a pair of parallel legs 14, 34 with coupling apertures 24, 44 at their
upper ends and elastomeric stoppers 18, 38 at their lower ends. Each leg assembly
has a plurality of steps 20, 40 extending transversely between the legs. Each of the
legs is fabricated of a plurality of components with apertures 44 and with the
components coupled together in telescoping relationship with a locking pin 46
positionable through alignable apertures in the areas of overlap and a spring 48 interior
thereof to hold the locking pin in a preset orientation. A coupling plate 50 is provided
having apertures 60 which align with the apertures 24, 44 at the upper ends of the legs
for effecting the pivotal coupling of the legs with respect to each other and the coupling
plate. Two pivotable locking bars 66 are provided to couple the front leg assembly 12
with the rear leg assembly 32.
Hutson's invention relates to an adjustable leg ladder assembly. As shown in
Figures 1-2, the adjustable leg ladder assembly 10 includes a top plate 24, a forward
ladder step support 26, and a rear A-frame support 28. The forward ladder step
support 26 includes two adjustable legs 34, 36, 48 and rungs 32. The rear A-frame
support 28 includes two adjustable legs 40, 42, 48. A pivoting foot pad is attached to
each adjustable leg.
