摘要： 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.

摘要： 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.

摘要： A folding step stool includes a front rail assembly. The step stool includes a rear rail assembly, pivotally connected to the front rail assembly, having a crossbar. The step stool includes a step pivotally attached to the front rail assembly having notches which fit over the crossbar when the stool is in an open position. The step stool includes a linkage assembly pivotally and fixedly attached to the step and pivotally and fixedly attached to the crossbar. The linkage assembly compresses to allow the notches to fit over the crossbar and the linkage assembly exerting a force to maintain the crossbar in the notches when the stool is in the open position. A method for securing a step stool includes the steps of moving the notches of a step against a crossbar of a rear rail assembly pivotally connected to a front rail assembly of the step stool. There is the step of compressing a linkage assembly pivotally and fixedly attached to the step and pivotally and fixedly attached to the crossbar to allow the notches to fit over the crossbar. There is the step of exerting a force with the linkage assembly to maintain the crossbar in the notches when the stool is in the open position.

摘要： A climbing apparatus that rests on a surface includes a flip ladder that can move between a straight configuration and a stepladder configuration. The apparatus includes a tray having a plane attached to the flip ladder that moves with the flip ladder between the straight configuration where the tray plane is essentially parallel with the ladder in a stowed position and a stepladder configuration where the tray plane is essentially parallel with the surface in an open position. A method for climbing includes the steps of moving a flip ladder between a straight configuration and a stepladder configuration. There is the step of moving a tray having a plane attached to the flip ladder from a stowed position where the tray plane is essentially parallel with the ladder to an opened position where the tray plane is essentially parallel with the surface. There is the step of moving the flip ladder from the stepladder configuration to the straight configuration which causes the tray to move automatically into the stowed position.
