Abstract

A step ladder device for balancing and stabilizing a ladder upon most any surface. The step ladder device includes a ladder having pairs of side rails and rung members being attached to the pairs of side rails; and also includes a ladder support assembly having leg assemblies including leg support members being attached to bottom ends of the side rails, and also including leg members being adjustably attached to the leg support members, and further including feet members being pivotally attached to the leg members.

Claims

1. A step ladder device comprising:

a ladder having pairs of side rails and rung members being attached to said pairs of side rails;

a ladder support assembly having leg assemblies including leg support members being attached to bottom ends of said side rails, and also including leg members being adjustably attached to said leg support members, and further including feet members being pivotally attached to said leg members, each of said leg members having a ball-shaped bottom end, and each of said feet members having a concave joint being disposed thereupon, each of said ball-shaped bottom ends of a respective said leg member being pivotally seated in said concave joint of a respective said feet member, said ladder support assembly also including leg stopper members being attached to top ends of said leg members to prevent said leg members from being removed from said leg support members, each of said leg support members being a plate having a hole being centrally-disposed therethrough, each of said leg members having external threads extending a length thereof and being threaded through said hole of a respective said leg support member, said ladder support assembly further includes including a tool holder being attached to one of said side rails of said ladder, and also includes including a socket wrench being removably held by said tool holder and having a handle portion and socket portion, said ladder support assembly also including hinge members being attached to outer sides of said side rails of said ladder and having opposed slots disposed in sides thereof, and further including leg assemblies being pivotally attached to said hinge members, each of said leg assemblies further including an elongate tubular member being hingedly attached to a respective said hinge member, and also including an elongate extension member having a ball-shaped bottom end and being telescopingly received in and extended from said elongate tubular member, and further including support feet having concave joint members being disposed thereupon for receiving said ball-shaped bottom ends of said elongate extension members, and further including bracket members being attached to a top end of said elongate tubular member and being fastenable to a respective said hinge member, and also including a fastener for fastening said elongate extension member to said elongate tubular member, each of said leg assemblies also including brace support brackets being attached to a selected said side rail and to a respective said elongate tubular member and further including an adjustable tubular brace member having ends which are fastened to said brace support brackets for stabilizing a respective said elongate tubular member and a respective said elongate extension member, each of said elongate tubular members having a plurality of holes being spacedly disposed through and along a length of a side wall of said elongate tubular member.

2. The step ladder device as described in claim 1, wherein each of said elongate extension members has a plurality of holes being spaced disposed in and along a length of a side wall thereof, said fasteners being insertable in said holes of said elongate tubular members and said elongate extension members.

3. The step ladder device as described in claim 2, wherein each of said bracket members has a slot disposed therein.

4. The step ladder device as described in claim 3, wherein said ladder support assembly further includes spring members being disposed in said slots of said bracket members, and also includes balls being attached to said spring members and being removably disposed in said slots of said hinge members to securely and removably attach said leg assemblies to said hinge members.
