Abstract
Raisable and lowerable platforms for use with ladders that are laid against exterior and interior walls, and against other inclined surfaces such as pitched roof surfaces. Two or more ladders can each include the platforms which are controlled by motors to raise and lower in unison. The platforms can be attached by rollers about exterior sides of the ladders or on the interior sides of the ladders, as needed. Single, two, or more ladder applications can include platforms being expandable to have enlarged surfaces. A longitudinal member such as a board, deck, etc., can also be positioned on the platform(s) so it can be used as a raisable and lowerable scaffolding system.
Claims8
A scaffolding system for two or more ladders, comprising in combination:
- a first ladder laid against a raised surface;
- a first moveable platform;
- first means for attaching the first platform on the first ladder;
- a first motor fixably mounted to a base portion of the first ladder;
- a second ladder laid against the raised surface being spaced apart from the first ladder, the first ladder and the second ladder being spaced apart from and not mechanically attached to one another;
- a second moveable platform;
- second means for attaching the second platform on the second ladder;
- a longitudinal member that is solely laid on both the first and the second platforms;
- a second motor fixably mounted to a base portion of the second ladder;
- and
- control means for simultaneously controlling the first motor and the second motor for simultaneously moving the first platform and the second platform up and down on the first and the second ladders, wherein the longitudinal member functions as. a moveable scaffold.
A raisable and lower enlargeable scaffolding system for ladders, comprising in combination:
- a first ladder for being laid against a raised surface;
- a first platform having a first layer in a folded sandwich orientation to a second layer, the folded sandwich orientation of the platform having a first upper surface area(being substantially parallel to a ground surface, the first upper surface area for supporting an object thereon;
- hinge means for enlarging the first upper surface area of the platform by unfolding the second layer relative to the first layer to an expanded unfolded position having an enlarged upper surface area, the enlarged upper surface area being larger than the first upper surface area;
- means for supporting the expanded unfolded position so that the enlarged upper surface area is substantially parallel to the ground surface;
- means for attaching the first platform to the first ladder
- a motor mounted on a bottom portion of the first ladder for moving the first platform up and down on the first ladder.
