Patent attributes
A collapsible ladder that collapse not only the rails but also the steps, as well as the top caps, so that the ladder may be erected and then collapsed flat, saving storage space. The ladder has a pair of right siderails rotatably connected to a pair of left siderails. The right top cap and the right steps are rotatably attached in between the pair of right siderails. The right top cap and the right steps are also rotatably attached in between the pair of right linking rails. Likewise, the ladder also has a pair of left siderails rotatably connected to a pair of left siderails. The left top cap and the left steps are rotatably attached in between the pair of left siderails. The left top cap and the left steps are also rotatably attached in between the pair of left linking rails. Because the siderails, the steps, the linking rails are all rotatably attached to form the ladder, the ladder may be open and erected and also may be folded and collapsed to save space for storage and for carrying.
