Abstract:
A device for vertically lifting and holding in position construction panels from bottom edge of panel on a flat surface to bottom edge of panel at a desired height relative to that surface comprising:a body structure; a lever arm which serves to raise the construction panels positioned on a lifting end of the lower arm when downward foot pressure is applied to a pedal attached to a second end of the lever arm; a lever arm support rod secured to the body and passing through a slot in a mid section of the lever arm which serves as a fixed fulcrum point for the lever arm; a lifting surface attached to the lifting end of the lever arm by means of a tab and bolt which allows the lifting surface to track upward in a vertical fashion along a surface of the body; a locking arm pivoting on a locking arm support rod attached to the body above the lever arm support rod which by gravity allows the locking arm to drop into serrations cut into the top of the lever arm thus locking the lever arm into position; a return spring connected from the base to the lever arm causing downward pressure on the lifting end of the lever arm and returning the device to the ready position when the locking arm is released by forward pressure; and a foot strap secured to the body allowing a user to insert a foot into the opening then raise the foot thus picking up the device, and carrying it to be positioned for the next operation.
