Abstract
A stepladder includes a front section having a first front leg and a second front leg. The stepladder includes a step attached to the first front leg and the second front leg. The stepladder includes a latch engaged with the step. The stepladder includes a rear section having a first rear leg and a second rear leg and a cross bar attached to the first rear leg and the second rear leg. The rear section is pivotably attached to the front section. The rear section has a first stud which extends from the first rear leg toward the second rear leg and separate and apart and not in contact with the second rear leg and not in contact with the cross bar. The latch is engaged with and latched to the first stud to define an engaged position where the first front leg and the first rear leg are in an open position and form an inverted v shape and are prevented from folding together, and the latch when pulled up from the engaged position, disengages from the first stud and allows the front section and rear section to fold together into a closed position where the first rear leg and the first front leg are in parallel. A method of positioning a step ladder.
