An improvement to U.S. Pat. No. 6,003,630 comprising a method and device whereby the extension arm portion is removably attached and to the nail plate portion while attached to the exterior scaffolding portion, thus permitting a single user to take down the scaffolding easily and safely on their own without assistance. Additionally, the scaffold can now be safely lowered to the ground entirely from the building interior via a support line attached to the extension arm while it is attached to the exterior scaffolding. This improvement makes the 630 patent more efficient and much safer to use. Additionally, a spanner bracket for use with cement block or pour in place concrete walls is disclosed herein enabling a non ground-based scaffolding system in use with the 630 patent for such walls types, also permitting single user set up and removal of the scaffolding.

1. A scaffold system configured to be removably attached to a support structure having an aperture extending therethrough, the scaffold system comprises: a scaffold configured to directly support a user when in a first position;an extension arm having a first end and a second end, wherein the scaffold is attached to the extension arm, and wherein the extension arm has an aperture extending therethrough proximate the second end;a nail plate having an aperture extending therethrough;a pin;a rope or cable;wherein the scaffold system is configured to move between the first position and a second position; wherein,when the scaffold system is in the first position, the extension arm extends through the aperture of the support structure, the rope or cable does not extend through the aperture of the support structure, the second end extends through the aperture of the nail plate, and the pin extends through the aperture of the extension arm which retains the extension arm and scaffold in a fixed position with respect to the nail plate and the support structure so that the scaffold is fixedly attached to the support structure; and,when the scaffold system is in the second position, the pin does not extend through the aperture of the extension arm, the rope or cable is directly attached to the second end of the extension arm, the rope or cable extends through the aperture in the nail plate and the aperture in the support structure, the scaffold is detached from the support structure and positioned at a first height below a second height of the scaffold in the first position as a result of the scaffold being substantially supported by the rope or cable while being raised or lowered by the rope or cable. 2. The scaffold system of claim 1, wherein at least the second end of the extension arm has a cylindrical shape. 3. The scaffold system of claim 1, wherein the extension arm is oriented substantially perpendicular to the nail plate. 4. The scaffold system of claim 1, and further comprising an eyelet attached to the second end of the extension arm, wherein the rope or cable is attached to the eyelet. 5. The scaffold system of claim 4, wherein the eyelet has a width that is no larger than a width of the aperture in the nail plate. 6. The scaffold system of claim 1, wherein the scaffold comprises: a vertical support member having a first end and a second end; anda horizontal support member having a first end and a second end, wherein the first end of the vertical support member is attached to the horizontal support member so that the vertical support member is substantially perpendicular to the horizontal support member. 7. The scaffold system of claim 6, and further comprising an attaching bracket port attached to the horizontal support member. 8. A method for lowering or removing the scaffold system of claim 4 from the support structure, the method comprising: providing the scaffold system;attaching the rope or cable to the extension arm;removing the pin from the aperture of the extension arm; andlowering or removing the scaffold system from the support structure by lowering the rope or cable while securing substantially an entire weight of the scaffold system with the rope or cable.
