    • 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.
    • 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。
