摘要:
The present invention relates to a collapsible device for assisting a construction worker in erecting a framed wall. The device includes an elongated telescoping arm having a planar foot member at a first end thereof for vertically securing the arm to a floor. A first end of an elongated nylon strap is attached to a retraction mechanism on the arm. A second end of the nylon strap has a bracket thereon for securing to the top of a wall. The telescoping arm has a weight indication means for indicating to a user the weight of a wall being erected thereby. Accordingly, the strap may be secured to a horizontally oriented wall and the nylon strap is retracted causing the wall to pivot to a vertical position. The telescoping arm allows the device to be easily collapsed for transport or storage.
