MULTI-POSITION LADDER, METHOD OF USING AND METHOD OF MAKING A MULTI-POSITION LADDER
A multi-function ladder having a front section having a first front rail and a second front rail and rungs attached to and between the first front rail and the second front rail. The ladder having a rear section having a first rear rail and a second rear rail and rungs attached to and between the first rear rail and the second rear rail. The rear section having a telescoping section attached to the first rear rail and the second rear rail to vary a length of the rear section. The ladder having a first hinge attached to the first front rail and the first rear rail. The ladder having a second hinge attached to the second front rail and the second rear rail. Each hinge having a locked state and an unlocked state. The ladder having an actuator directly attached to the front section and remote and separate and apart from the first hinge and the second hinge. The actuator when actuated moving the first and second hinges between the locked state and the unlocked state. When the first and second hinges are in the unlocked state, the rear section can be moved between a leaning ladder mode, a step ladder mode, a stairway ladder mode and a straight ladder mode upon which each hinge goes into the locked state in the desired ladder mode. A method for using a multi-position ladder. A method for producing a multi-position ladder. An actuator for locking and unlocking a first hinge and second hinge of a ladder.
