摘要： A ladder includes a first section having at least one step. The ladder includes a second section having a least one step. The ladder includes a platform attached to the first and second sections. The ladder includes a hinge mechanism connected to the first section and second section, about which the first section and second section move between an open state, where the first and second sections are in an angular relationship for use, and a folded state where the first and second sections and the platform are essentially in parallel, as shown in FIGS. 4 and 5.The ladder includes a foldable tray mechanism attached to the hinge mechanism about which the foldable tray mechanism moves between the open state independently of the first and second sections, where the foldable tray is in an angular relationship with the first and second sections for use, and a folded state where the foldable tray essentially forms a plane with the first section. A hinge for a stepladder. A step to a ladder. Methods for using a stepladder.

摘要： A lifeline system includes a lifeline and a drum assembly around which the lifeline is coiled. The drum assembly is rotatable about a first axis in a first direction during extension of the lifeline and in a second direction, opposite of the first direction, during retraction of the lifeline. The lifeline system further includes a tensioning mechanism in operative connection with the drum assembly to impart a biasing force on the drum assembly to bias the drum assembly to rotate about the first axis in the second direction. The lifeline system further comprises a braking mechanism in operative connection with the drum assembly. The braking mechanism includes a catch that is rotatable relative to the drum assembly about a second axis that is not concentric with the first axis. The second axis is operatively connected to the first axis so that the second axis rotates about the first axis in the same direction as the drum assembly when the drum assembly is rotating about the first axis. A center of mass of the catch is located in the vicinity of the second axis. The catch rotates about the second axis in the second direction when the drum assembly is rotated in the first direction at at least a determined angular acceleration to cause an abutment section of the catch to abut an abutment member of the lifeline system (for example, by moving radially outward a sufficient amount) and stop the rotation of the drum assembly.
摘要翻译：生命线系统包括救生索和围绕生命线盘绕的鼓组件。在救生索的缩回期间，滚筒组件可在第一方向上沿着第一方向旋转，并且在第二方向上与第一方向相反。救生索系统还包括与滚筒组件可操作地连接的张紧机构，以在滚筒组件上施加偏置力，以偏置滚筒组件以沿着第二方向围绕第一轴线旋转。救生索系统还包括与鼓组件有效连接的制动机构。制动机构包括可相对于滚筒组件围绕不与第一轴线同心的第二轴线旋转的卡扣。第二轴线可操作地连接到第一轴线，使得当滚筒组件围绕第一轴线旋转时，第二轴线以与鼓组件相同的方向围绕第一轴线旋转。卡盘的质心位于第二轴附近。当滚筒组件以至少一个确定的角加速度在第一方向上旋转时，卡爪在第二方向上围绕第二轴线旋转，以使卡扣的邻接部分邻接救生索系统的邻接构件（例如，由径向向外移动足够的量）并停止鼓组件的旋转。

摘要： A folding step stool includes a hinge mechanism. The step stool includes a first section connected to the hinge mechanism. The first section having a bottom step. The step stool includes a second section connected to the hinge mechanism. The step stool includes a third section connected to the hinge mechanism, wherein when the folding step is in and unfolded state, the first and second sections form a base on a floor and are in angular relationship with each other, and the third section extends upward from the hinge mechanism relative to the first section, and when the first, second and third sections are in a folded state, they are essentially in parallel with each other, are no more than ¾ as tall and ½ as long as when the step stool is in the unfolded state. A method for using a folding step stool. A hinge for a folding step stool having a folded and unfolded state and having a top rail, front rail and rear rail. A method for using a folding step stool.

摘要： A strand grab for a ladder having a hook assembly, a gate assembly engaged with the hook assembly and a biasing spring. The biasing spring produces a return biasing force which is less than a weight force of the ladder when the hook assembly rests on the strand allowing the gate assembly to close with the hook assembly and squeeze the strand between the gate assembly and the hook assembly in a closed position and hold the ladder in place with the strand. A ladder for use with a strand having a first rail and a second rail. The first rail has a first strand grab directly attached to the first rail and the second rail has a second stand grab directly attached to the second rail. A method for using a ladder. A method for making a ladder.
