The present invention is used on stepladders that are structured to provide improved lateral stability, step support and equipment/supplies support for stepladder users. The stepladder may have a step element and a support element rotatably attached at a top platform or a first step element rotatably attached to a second step element adjacent a top step. A hinged strut may be attached at opposed ends between the opposed elements intermediate the ladder top and the ladder base. A plurality of steps may be spaced apart and attached between step rails of step elements. A lateral support leg may be rotatably attached at a top end to each of the step rails intermediate a second step and a third step from the ladder top and a hinged leg strut may be attached at opposed ends between each of the support rails and lateral support legs.

1. A stepladder comprising: a step element and a support element each rotatably attached in opposed relationship at a top platform wherein said step element has two spaced apart step rails with a plurality of steps spaced apart and attached therebetween, and said support element has two spaced apart support rails with at least one support member attached therebetween;a hinged strut is attached between each step rail and each opposed support rail intermediate said top platform and a ladder base;two lateral support legs each have a lever strut rotatably attached at a first end to a top end of each of said lateral support legs and one of each of said two lateral support legs is rotatably attached at a second end to each of said step rails intermediate a second step and a third step from said top platform;a lower strut is rotatably attached at opposed ends to said lateral support leg and said step rail below and spaced apart from said lever strut;wherein when said lateral support legs are deployed, a foot end of each is spaced apart from its attached step rail one half the width of the distance between a bottom end of each of said two step rails; andwherein a first capped lug is attached adjacent said top platform on said step rail and a second capped lug is attached adjacent said top platform on said support rail; and a utility tray having four side walls with one of said side walls having at least two slots formed therein for engagement with said capped lugs is disposed on the stepladder. 2. The stepladder as in claim 1 wherein said utility tray has a width to extend perpendicularly from the plane of said first capped lug and second capped lug from said step rail a distance approximately equal to the separation distance between a bottom end of said step rail and a foot of said lateral support leg when deployed. 3. A stepladder comprising: a first step element and a second step element each with a first step rail, a second step rail and a top step wherein said first step element and said second step element are rotatably attached by a first hinge and strut combination that is attached at a first end to said first step rail of said first step element and at a second end to said first step rail of said second step element and by a second hinge and strut combination that is attached at a first end to said second step rail of said first step element and at a second end to said second step rail of said second step element wherein said first hinge and strut combination and said second hinge and strut combination are disposed adjacent to and below said top step of each of said first step element and said second step element wherein each of said first and second hinge and strut combinations is a hinge spaced apart from a strut wherein said strut is positioned below said hinge and a slot in said strut is engaged with a capped lug in said strut;a hinged strut is attached at opposed ends between each of said first step rails and between each of said second step rails of said first step element and said second step element intermediate said top steps and a ladder base;a plurality of steps spaced apart and attached between said first and second step rails of said first step element and said first and second step rails of said second step element;a plurality of lateral support legs each have a lever strut rotatably attached at a first end to a top end of each of said lateral support legs, and one of each of said lever struts at a second end is rotatably attached intermediate a second step and a third step from said top step of said first step element to each of said first and second step rails of said second step element to each of said first and second step rails;a lower strut is rotatably attached at opposed ends to each of said lateral support legs and said first and second step rails below and spaced apart from said lever strut;wherein when said lateral support legs are deployed, a foot end of each is spaced apart from its attached step rail one half the width of the distance between a bottom end of each of said first and second step rails; andwherein a capped lug is attached adjacent said top steps on each of said first step rails and said second step rails, and a utility tray having four side walls with one of said side walls having at least two slots formed therein for engagement with said capped lugs is disposed on the stepladder. 4. The stepladder as in claim 3 wherein a safety handle has an elongated shaft with an angular bar attached approximately orthogonally at one end and a clamp is attached to one of said step rails adjacent said top step wherein said clamp is disposed for slidable insertion of said elongated shaft to position said angular bar above said top step and to retain said elongated shaft.
