Stepladder with latch stud and method
View Patent ↗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.
1. A method of positioning a stepladder, the method comprising the steps of:
providing the stepladder, the stepladder comprising:
a front section having a first front leg and a second front leg, a step configured to support a user, the step being attached to the first front leg and the second front leg, the step including a first side, a second side, a front, a rear, a first step link attached to and positioned between a first rear leg and the first side of the step, the step including a second step link attached to and positioned between a second rear leg and the second side of the step, a latch engaged with the step, a rear section having the first rear leg, the second rear leg and a cross bar directly attached to and between the rear legs, the rear section pivotably attached to the front section, the first rear leg directly connected to a first stud, the first stud extending from the first rear leg toward the second rear leg, the first stud being separate and apart and not in contact with the second rear leg and not in contact with the cross bar, the second rear leg directly connected to a second stud, the second stud extending from the second rear leg toward the first rear leg, the second stud being separate and apart and not in contact with the first rear leg and the first stud and not in contact with the cross bar, the latch configured to move between an engaged position and a disengaged position, the latch configured to be directly latched to the first stud to lock the first front leg and the first rear leg in an open position forming an inverted V shape when in the engaged position, wherein the latch prevents the front and rear sections from folding together when in the engaged position, the latch configured to be pulled up from the engaged position to the disengaged positioned to disengage the latch from the first stud to allow the front and rear sections to fold together into a closed position in which the first rear leg and the first front leg are in parallel, the latch includes a latch bar directly connected to and between a first latch end and a second latch end, the second latch end configured to engage with the second stud, the latch bar configured to cause the first and second latch ends to move in unison, the latch bar being disposed below the step when the latch is in the engaged position, the latch includes a restoring mechanism configured to bias the first and second latch ends toward the engaged position, the restoring mechanism includes a first spring which engages with the first latch end and a second spring which engages with the second latch end, the crossbar directly contacting and supporting the rear of the step when the latch is in the engaged position, each of said latch ends has a cam portion and hook portion; the latch ends configured so that as the cam portion contacts a respective stud of said first and second studs when the rear of the step is moved downward toward the open position, the cam portion moves so that the hook portion bypasses the respective stud until the hook portion clears the respective stud which causes a respective spring of said springs to bias the hook portion to engage the respective stud to place the latch into the engaged position;
pivoting the front section relative to the rear section in order to pivot the ladder into the open position;
engaging the latch to the first stud in order to position the stepladder into the engaged position;
pulling up on the latch in order to move the latch from the engaged position to the disengaged position; and
folding the front and rear sections together into the closed position.
2. The method of claim 1 , further comprising the steps of:
contacting the first stud with a first of said cam portions;
moving the first of said cam portions so that a first of said hook portions bypasses the first stud; and
moving the first of said hook portions to engage the first stud in order to place the latch into the engaged position after the first of said hook portions clears the first stud.
