ABSTRACT:
The present invention pertains to a plastic ladder. The plastic ladder includes a front section which has a first hollow side rail and a second hollow side rail disposed essentially in parallel with the first side rail. The first and second side rails are made of plastic and have reinforced pockets disposed along the respective rails at predetermined locations. The plastic ladder also has a plurality of hollow plastic steps. Each of the steps is attached to the first and second rails at corresponding reinforced pockets therein such that each step forms a flat weight bearing platform upon which a user can stand. Each step has blow molded tread patterns which provide a slip resistant surface. The ladder also has a rear section comprised of a third hollow plastic side rail and a fourth hollow plastic side rail disposed essentially in parallel with the third hollow plastic side rail. The third and fourth hollow plastic side rails have reinforced pockets disposed along the respective rails at predetermined positions for attaching a plurality of hollow plastic bracing elements. Moreover, the ladder has a plastic top which is connected to the front and rear sections at the ends of the first and second side rails, at the ends of the third and fourth rails, respectively, such that the front and rear sections form a v-shape when deployed and folded on top of each other when undeployed.
