Abstract

The invention provides a foldable ladder. The foldable ladder comprises a first piece of ladder and a second piece of ladder which are hinged with each other, wherein the first piece of ladder comprises a first vertical edge of the first piece of ladder, a second vertical edge of the first piece of ladder and a horizontal ladder; the first vertical edge of the first piece of ladder and the second vertical edge of the first piece of ladder are respectively located at two side edges and are connected by the horizontal ladder; the second piece of ladder comprises the first vertical edge of the second piece of ladder, the second vertical edge of the second piece of ladder and the horizontal ladder; the first vertical edge of the second piece of ladder and the second vertical edge of the second piece of ladder are respectively located at the two side edges and are connected by the horizontal ladder; a first supporting point for supporting an operating surface is arranged at the lower end of the first vertical edge of the first piece of ladder; a second supporting point for supporting the operating surface is arranged at the second vertical edge of the first piece of ladder; a third supporting point for supporting the operating surface is arranged at the first vertical edge of the second piece of ladder; a fourth supporting point for supporting the operating surface is arranged at the second vertical edge of the second piece of ladder; the first supporting point and the third supporting point are located on the same side of the foldable ladder; and the second supporting point and the fourth supporting point are located on the other side of the foldable ladder.

Description

technical field [0001] The invention relates to a foldable ladder, that is, the invention relates to a foldable ladder. Background technique [0002] Ladder is a tool commonly used in people's life and work. At present, the commonly used folding ladders on the market are divided into two hinged ladders. When in use, the two hinged ladders are opened, and the whole folding ladder is supported on the ground in a herringbone shape. People can stand on the ladder or the pedals on the ladder. When working, the two ladders can be combined together when not working, so this kind of ladder is also called a herringbone ladder. Although the folding ladder is supported on the ground in a herringbone shape, which can prevent the folding ladder from toppling forward and backward in the herringbone plane, the folding ladder is supported on the ground by four points or two parallel lines, and the folding ladder is easy to move vertically to the herringbone plane. Direction topples, that ...
