  • 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: 8123001
    Abstract: A combination of parts for and method of constructing a modular platform. A frame beam connector member is connected to respective end portions of a pair of frame beams while the pair of frame beams are in substantially a side-by-side relation. One of the frame beams is then swung relative to the other to a co-axial position of the frame beams relative to each other. Then another frame beam connector member is connected to the respective end portions of the frame beams while the frame beams are in the co-axial position thereby to maintain the pair of frame beams in the co-axial position. A deck support beam is connected to a frame beam while in substantially a side-by-side relation therewith. The deck support beam is then swung to a position normal to the frame beams. The deck support beam is then connected to another frame beam.
