摘要： A brace rail shield combination for a rail of a ladder having at least one rung having a first portion that has a shape that conforms with an interior cross sectional surface of the rail. The brace rail shield combination includes a second portion that extends from the first portion at a first location to the rung to provide structural support to the rung. The second portion having an attachment portion at a second location spaced apart from the first location that is fixed to the rung. The first portion and the second portion being one continuous piece. A method for using an extension ladder, A method for producing a knee brace rail shield combination.

摘要： A method for manufacturing a rail for a ladder. The method may include pultruding in a longitudinal direction, a rail having a selected cross-sectional shape. The rail may then be cut to a predetermined length at a distal end. A force may be applied, in a lateral direction, to the rail to form a curvature therein. The curvature may be characterized by a flared portion, a straight portion, and a curved region providing the transition therebetween. The rail may be held at the desired curvature for a time selected for the rail to take on the curvature substantially permanently. The force may then be removed and the rail may be assembled into a ladder.

摘要： A load-dispersing device for non-free standing ladders or other devices that require reduction of horizontal slippage. The single strip load-dispersing bumper can be used in combination with a ladder having side rails with a load-bearing surface. The bumper consists of a pair of flexible, resilient, load-dispersing members, each of which has a contact area and a method of affixing the members to the ladder. A first side of the contact area is placed adjacent and secured to the load-bearing surface. The second side of the contact area is placed between the load bearing surface and a support surface to prevent the ladder from sliding. The bumper can be affixed to the load bearing surface by an adhesive, tape or hook and loop material or using multiple dome-topped pins that are integral with the first side. The dome-topped pins are dimensioned to fit within holes that are placed along the load-bearing surface. A retaining clip encompasses the contact area and at least a portion of the ladder side rails to protect the end of the bumper. The retaining clip can be a soft metal having a body having a notch to receive the bumper and a pair of parallel flanges for crimping around the side rails.
摘要翻译：用于非自由式梯子或其他需要减少水平滑动的装置的分散装置。单条负载分散保险杠可以与具有承载表面的侧轨的梯子组合使用。保险杠由一对柔性，弹性的负载分散构件组成，每个构件具有接触区域和将构件固定在梯子上的方法。接触区域的第一侧邻近并固定到承重表面。接触区域的第二面被放置在承载表面和支撑表面之间，以防止梯子滑动。保险杠可以通过粘合剂，胶带或钩环材料或使用与第一面成一体的多个圆顶顶针固定在承载表面上。圆顶顶针的尺寸适合安装在承载表面上的孔内。保持夹包围接触区域和梯子侧轨道的至少一部分，以保护保险杠的端部。保持夹可以是软金属，其具有用于容纳保险杠的凹口的主体和用于围绕侧轨卷曲的一对平行凸缘。

摘要： This invention relates to a process and a device for an angular connection of the end of a tube with one (or more) sheet metal element(s), quickly and reliably.The forward portion of a tubular shape (1) is contracted by force-fitting in a ring (2) whose outside dimensions are approximately equal to those of the opening (4) and the inside dimensions, less than the initial outside dimensions of the tubular shape, and whose rear end (6) is flush with the rear face (7) of the sheet metal (3), this ring (2) being compressed on the thickness of the sheet metal (3) between the tubular shape (1) and the opening (4) in the sheet metal, while the end (10) of the tubular shape is flanged outward in a corolla on the rear face (7) of the sheet metal element.This process can be used in particular to attach rungs to side rails of a ladder or rods to rails of guard railings and also for making scaffolding or tube exchangers.

摘要： A metal ladder, in which each stile has a pair of spaced parallel ribs on its inner and outer faces, and is formed with pairs of slots close to the ribs, and each rung has a cross section in the form of a hollow parallelogram, with two spaced parallel tabs projecting at each end. The tabs are inserted through the slots and crimped over the outer ribs, and the sidewalls of the rungs locate against the ribs on the inwardly facing surfaces of the stiles.
