Abstract

The present invention discloses multifunction ladder structures. The first embodiment includes a first ladder frame; a second ladder frame; and two combining assemblies that combine the second ladder frame with the first ladder frame. Another embodiment further includes an extension board, while a third embodiment includes two bolts set detachably fixed to the second ladder frame. With the implementation of the present invention, the multifunction ladder structures have the special benefit of being easy to install or operate; being able to insert and set firmly in between a tire and the wheel fender as a tire ladder; being able to stand firmly beside a car or other places as an A-shaped ladder; applying to tires of different size by adjusting the length of the foot rods; standing firmly on rough or inclined ground, roads or object surfaces; and with the adoption of the extension board, versatile applications are accomplished.
