Abstract: An adjustable stepladder is provided including a first set of rails, having a plurality of rungs coupled therebetween, and a second set of rails, also having a plurality of rungs disposed therebetween, slidably coupled with the first set of rails. A single support leg is hingedly coupled with one set of rails and may include a telescoping structure. The support leg may include a base having a plurality of feet wherein the base is integrally formed with a structural member of the support leg. In another embodiment, a removable base may be coupled to a structural member of the support leg such that differently configured bases may be attached to the support leg. The stepladder may, thus be adjustable in terms of height as well as in terms of a support base which will be in contact with the ground or other supporting surface when the ladder is in use.

Abstract: An extensible, self locking platform includes a first assembly having a first plurality of substantially parallel longitudinally extending members and a second assembly having a second plurality of substantially parallel longitudinally extending members. The first and second assemblies are longitudinally, slidably coupled with each other. The platform may also include one or more catch devices. In one embodiment, at least one catch member is pivotably coupled to the first assembly with an associated stop member. The stop member is configured to maintain a rotation of the at least one catch member at less than a full revolution such that when the catch member is being abutted against an elevated support structure and the platform is being laterally displaced relative thereto, the catch member will also abut the stop member and prevent further displacement of the platform relative to the elevated support structure.
