Abstract
A space saving ladder, wherein the ladder can be folded up into a compact unit for storage. In the open load bearing orientation, the space saving ladder is load bearing and conforms to requirements for free standing ladders. In the closed orientation, the space saving ladder can have steps or rungs, which can hinge upward as the ladder legs are moved closer to one another. In the closed orientation, the legs of the space saving ladder are adjacent to one another and the steps or rungs are enclosed in the ladder legs.
Claims17
A space saving ladder comprising:
- a. a first leg and a second leg, parallel to each other, wherein each leg comprises a detent receptor;
- b. a plurality of pivoting steps, wherein each pivoting step is connected to the first leg with a first pivoting hinge and is connected to the second leg by a second pivoting hinge, wherein the pivoting hinges allow the space saving ladder to move between an open load bearing orientation and a closed orientation;
- and
- c. at least one locking step, wherein the at least one locking step is connected to the first leg with a first locking hinge and is connected to the second leg by a second locking hinge, wherein the first locking hinge and the second locking hinge each comprise a first detent pin and a second detent pin;
- and
- wherein, in the open load bearing orientation, the first detent pin locks into the detent receptor;
- wherein, in the closed orientation, the second detent pin locks into the detent receptor;
- and
- wherein, in the closed orientation, the first leg and the second leg are adjacent to each other, and the pivoting steps and the locking steps are disposed completely within the leg.
