  • Patent number: 9482020
    Abstract: A method of assembling an offset working surface on a scaffold. The method uses a scaffold knee-out member having a first and second scaffold members that are pivotally connected. A scaffold connector is positioned on an opposite end of each of the first and second scaffold members remote from the pivot point. Preferably, both connectors are pivotally connected to their respective scaffold members. One of the scaffold members of the knee-out end is coupled to a vertical scaffold, and then the other scaffold member of the knee-out is moved appropriately to allow the first and second scaffold members to pivot with respect to each other, until the other scaffold member is positioned to be coupled to a vertical scaffold member.

  • Patent number: 7077239
    Abstract: The invention is a scaffold access system for use in a scaffold frame of horizontal and vertical scaffold members. The system includes double barrel scaffold horizontal member, a series of short scaffold boards, a series of long scaffold boards, a short vertical scaffold member, a safety gate, and a series of short horizontal members. The double barrel scaffold horizontal member has a upper tube and a lower tube joined in a vertical relationship and a third tube slidable in the lower tube. Each tube has an interior and an exterior end. The upper tube and the third tube have an attachment member positioned on its respective exterior end. The upper tube has an upstanding vertical stub, to which is attached the short vertical scaffold member. The short scaffold boards and the long scaffold boards are placed on the scaffold frame to define a scaffold deck with an access opening.
