摘要： A ladder having a foot having a plastic body with a recess which receives the end of a first rail and is positioned about and conforms to the web and the first and second flanges of the first rail. The foot has a plastic base having a top side from which the body extends. The base has a front edge. The foot has a metal rail fastener which extends through the body and the rail to attach the body and the rail together. The foot has a pad having a rigid plate with a rubber outer layer surrounding the rigid plate and a pad fastener hole that extends entirely through the rigid plate and rubber outer layer, the outer layer of the pad having a bottom with treads. The foot has a metal pad fastener that extends entirely through the pad and entirely through the base to attach the pad to the base so the rigid plate is between the treads and the base of the shell.

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 stepladder includes a front section having a first front leg and a second front leg and a step attached to the first front leg and the second front leg and 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 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.

摘要： An access ladder for an access hole in a building includes a plurality of sections which telescope relative to each other between an extended position, where the sections define a plane and a user can climb the sections, and a retracted position where the sections are folded on each other. Several of the sections have a least one step which preferably moves between an unfolded position where the user can stand on the step when the sections are in the extended position, and a folded position when the sections are in the retracted position. Each section slides relative to another section of the plurality of sections which it is in contact in order for the sections to telescope. A method for using an access ladder attached to an end of an access hole of a building.

摘要： A coupling device for connecting a handle part and a tool part includes a plug and a socket. The plug has a main portion, an end portion, and a notched portion between the main portion and the end portion. The socket has a proximal base end, a body portion, and a locking member. The body portion extends from the base end and has an axial, plug receiving bore that opens through a distal end of the body portion. The locking member is positioned between the base end and the plug receiving bore. The locking member includes a leaf spring cantilevered axially on one side of the body portion of the socket. The leaf spring supports a latch bar that engages the notched portion of the plug when the plug is inserted through the open end of the plug receiving bore. The latch bar is spaced from the leaf spring so that the end portion of the plug passes between the latch bar and the leaf spring when the plug is inserted through the open end of the plug receiving bore. The latch bar is released from the notched portion of the plug when the leaf spring is depressed inwardly from the one side of the socket body.
