Abstract
An improved method and apparatus of scaffolding during building has a scaffold with folding hanger and work frames, storable bumpers on the work frame for propping the scaffold off of a wall, and a hanger structure in the hanger frame for suspending the scaffold from the cap or upper header of a building wall. The scaffold is also usable as a sawhorse and a ground/floor supported scaffold. The method of scaffolding provides the steps of hanging the scaffold from the header or cap, propping the scaffold off with storable bumpers, and folding the scaffold flat for storage and transportation.
Claims20
A scaffold comprising
- (a) a work frame having a ladder;
- (b) a hanger frame having means for hanging the scaffold on a building wall;
- (c) means for folding the hanger frame from a use configuration which is extended upward from said work frame, to a storage configuration parallel to and alongside the work frame;
- (d) bumper means normal to said work frame for pushing the work frame off of the building wall;
- and
- (e) means for securing and storing said bumper means in a storage position parallel to said work frame.
A scaffold comprising
- (a) an upper generally trangular shaped hanger frame;
- (b) a hanging hook on an upper acute apex of said hanger frame;
- (c) a ladder hanging downward from a generally horizontal base member of said hanger frame, said ladder being spaced outward from an upright base member of said hanger frame;
- (d) a lower bumper rung secured to said ladder and spaced below said hanger frame, said bumper rung having an inboard bumper end that is generally flush with said hanger frame upright base member;
- (e) a bumper bar on the inboard end of said bumper end,
- (f) bumper locking means for locking said bumper to said bumper end in a position normal to a plane of said ladder;
- and
- (g) bumper storage locking means for alternatively locking said bumper to said ladder in storage position parallel to said ladder plane.
A method of using a scaffold comprising the steps of
- (a) opening a hanger frame and a work frame from a side-by-side storage configuration to an in-line co-planar use configuration;
- (b) affixing at least one bumper in a usage position that is normal to the work frame;
- (c) hanging the opened scaffold upon the top of a wall and suspending the weight of the scaffold and any load thereon from the top of the wall;
- (d) pushing the work frame off of the wall with the bumper;
- (e) lifting and removing the scaffold up and off of the wall upon completion of construction;
- (f) relocating the bumper and securing and storing it parallel to the work frame;
- and
- (g) folding the hanger frame over and alongside the work frame and into the storage configuration, so that said scaffold is flat for storage or transportation.
