摘要： A knee brace for a ladder including a first flange and a second flange. The brace includes a web extending from the first flange and the second flange which together form a u-shaped cross-section. The brace includes a first portion that connects to a step. The brace includes a second portion which connects to the rail and terminates at a distance from a joint. The second portion's first and second flanges and web presenting three contact surfaces which connect to the rail and extend essentially in parallel with the rail and conforms with the rail to which the knee brace is attached so forces can be transferred therebetween. The first and second flanges contact a first rail flange and second rail flange, respectively, and the web contacts the web of the rail of u-shaped cross-section. The brace includes a first rivet extending through the first rail flange and first flange. The brace includes a second rivet extending through the second rail flange and the second flange adjacent the rail end. A method for using a ladder.
摘要翻译：一种用于梯子的膝盖支架，包括第一凸缘和第二凸缘。支架包括从第一凸缘和第二凸缘延伸的网，它们一起形成U形横截面。支架包括连接到台阶的第一部分。支架包括连接到导轨并终止于距离接头一定距离的第二部分。第二部分的第一和第二凸缘和腹板呈现三个接触表面，其连接到轨道并且基本上平行于轨道延伸并且符合与膝盖支撑件相连接的轨道，因此可以在其间传递力。第一和第二凸缘分别接触第一导轨凸缘和第二导轨凸缘，并且腹板接触U形横截面的导轨腹板。支架包括延伸穿过第一导轨凸缘和第一凸缘的第一铆钉。支架包括延伸穿过第二轨道凸缘的第二铆钉和邻近轨道端的第二凸缘。使用梯子的方法。

摘要： A folding ladder assembly having a door, a frame, and a strut connecting the door and frame. The strut comprises a first end and a second end opposite the first end. The first end of the strut is attached to the door via a strut stop bracket. The other end of the strut is attached to a stationary mounting plate, which is attached to the ladder opening frame. The strut is attached to the strut bracket via a strut standoff using an E-clip retaining ring. Optionally, the strut standoffs are riveted to the strut stop bracket and the stationary mounting plate. The strut stop bracket is optionally formed having a double bend to form two substantially parallel portions connected by a third non-parallel portion.
摘要翻译：具有门，框架和连接门和框架的支柱的折叠梯子组件。支柱包括与第一端相对的第一端和第二端。支柱的第一端通过支柱止动支架连接到门上。支柱的另一端连接到固定的安装板，该固定安装板连接到梯子开口框架。支柱通过支架支架连接到支柱支架上，使用E形夹固定环。可选地，支柱支座铆接到支柱止动支架和固定安装板。支柱止动支架可选地形成为具有双弯曲以形成由第三非平行部分连接的两个基本上平行的部分。

摘要： A hook attachment for a ladder is provided and includes a pair of curved members, each of the curved members being formed in a tapered shape having a base portion of a first cross-sectional area and a tip portion of a second cross-sectional area smaller than the first cross-sectional area. A cross-sectional area between the base portion and the tip portion decreases in a substantially continuous manner in a direction from the base portion to the tip portion.

摘要： A ladder includes a pair of opposing side rails and at least one attachment device configured to be attached to a fall arresting device. The opposing side rails have a plurality of steps disposed therebetween along substantially an entire length of the opposing side rails. The attachment device is configured to be attached to a fall arresting device and is substantially centrally disposed between the pair of opposing side rails. The attachment device is a plate, substantially parallel to a plane defined by the opposing side rails, that extends from one of the side rails to the other side rail. The ladder includes a pair of curved members respectively extending from the pair of opposing side rails at an upper distal end of the ladder. One of the attachment devices is positioned substantially centrally along a longitudinal axis of the ladder, and another of the attachment devices is positioned substantially proximate to the upper distal end of the ladder.
