ABSTRACT:
A stepladder having a pair of legs and two or more steps wherein the steps are pivoted to one of the legs and to guide members. Each of the legs includes a pair of side members. The guide members are spaced from and parallel to the side members of the first leg. When the ladder is in a position of use a latching device locks the second leg and the guide members together and helps transmit a load on the steps to the second leg. When the ladder is in a transport position the tread surface of the steps is disposed in a plane that is common to the plane formed by a rear surface of the second legs. The pivot connections between the steps and the first and second legs and the dimensions therebetween assure the same security in using the stepladder as is obtained by using fixed steps.
