Abstract:
Disclosed is a deformable herringbone ladder with straight ladder function, comprising a left ladder rack, a right ladder rack and a hinge mechanism, the left ladder rack and the right ladder rack are relatively rotatable to switch the ladder between a herringbone ladder state and a straight ladder state; wherein the left ladder rack comprises two left legs and an even number of left footboards connecting the two left legs, the left footboards are parallel arranged in equal spacing, the distance between two adjacent left footboards is defined L 1 ; the distance between two adjacent right footboards is defined L 2 ; in the straight ladder state by rotating, the distance between the left footboard at the top portion of the left ladder rack and the right footboard at the top portion of the right ladder rack is defined L 3 ; L 1= L 2= L 3 . The present invention conforms the Europe and America's safety technical standard.

Claim (Index 1):
A deformable herringbone ladder with straight ladder function, comprising a left ladder rack, a right ladder rack and a hinge mechanism, the top portion of the left ladder rack is connected to the top portion of the right ladder rack by the hinge mechanism, the left ladder rack and the right ladder rack are relatively rotatable to switch the ladder between a herringbone ladder state and a straight ladder state; wherein the left ladder rack comprises two left legs and an even number of left footboards connecting the two left legs, the left footboards are parallel arranged in equal spacing, the distance between two adjacent left footboards is defined L 1 ; the right ladder rack comprises two right legs and an odd number of right footboards connecting the two right legs, the right footboards are parallel arranged in equal spacing, the distance between two adjacent right footboards is defined L 2 ; in the herringbone ladder state, the rotating center of the hinge mechanism is disposed between the left ladder rack and the right ladder rack, and the height of the rotating center of the hinge mechanism is disposed between the highest point and the lowest point of the footboard at the top portion of the herringbone ladder; in the straight ladder state by rotating, the left ladder rack is in line with the right ladder rack, the distance between the left footboard at the top portion of the left ladder rack and the right footboard at the top portion of the right ladder rack is defined L 3 ; therein L 1 =L 2 =L 3 .
