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.

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： 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 long-handled shovel includes a head having a blade and a socket and an elongate handle member partially extending into the socket of the head. The handle member is a tube. A rod partially extends into the handle member and partially extends into the socket to provide resilient flexing between the head and the handle member when prying forces are applied thereto. A collar encircles the socket to limit outward expansion of the socket. A continuous outer layer of plastic material is molded over the entire length of the handle member and at least partially molded over the socket and the collar. The outer layer provides added strength by extending over the joint between the handle member and the socket.

摘要： A system includes a support including an extending rigid member and a first attachment at a first position on the rigid member to which a first self-retracting lifeline is attached. The first self-retracing lifeline includes a first housing from which a first lifeline exits. The first housing is movable relative to the rigid member. The system also includes at least a second attachment at a second position on the rigid member to which a second self-retracing lifeline. The second self-retracting lifeline includes a second housing from which a second lifeline exits.

摘要： A scaffold upon which a person stands includes a platform with a first leg assembly rotatably attached to the platform. The scaffold includes a latch assembly having a latch pivot axis coupled to the platform. The scaffold includes a stud attached to a first leg of the first leg assembly to which the latch assembly engages when the first leg assembly is moved into the extended position to automatically lock the first leg assembly in the extended position where the latch assembly is in a set position. When the latch assembly is moved out of the set position, the stud on the first leg disengages from the latch assembly and the first leg assembly is able to rotate about the first leg assembly pivot axis to a folded position. A method for using a scaffold.

摘要： An energy absorber including a strap including at least a first path of relatively reduced strength extending over at least a portion of the length of the strap. The energy absorber also includes at least a first transition region including a first initial point where tearing begins along the first transition region when a force above a threshold force is applied (to the energy absorber/strap) and a first end point. The first end point is in operative connection with a first point on the first path so that tearing continues along the first path after tearing along the first transition region. A gradual increase in load occurring as tearing occurs along the transition region.
