摘要： Provided is an adjustable extension for attachment to a ladder leg. The extension has an extension body and a friction surface that presses against the extension body to prevent movement of the extension body. The extension also includes a retainer that engages a retainer catch attached to the extension body to releasably hold the extension body in a retraced position, thereby allowing for one-handed operation and easy transportation of the ladder.

摘要： Provided is an adjustable extension for a ladder leg having an outer housing, an inner housing movable longitudinally relative to the outer housing in first and second directions opposite one another, and a stabilizer arm pivotably coupled to and movable with the inner housing. The stabilizer arm is pivotable about an axis perpendicular to the first and second directions such that the stabilizer arm is rotated relative to the inner housing to contact a surface to stabilize the extension in a sideways direction perpendicular to the first and second directions.

摘要： Improvements to the leg extension of an adjustable ladder leveler and, more generally, improvements to ladder legs. A shoe with a claw that folds to be parallel to the ladder leg and then slides upward with respect to the leg thereby becoming locked into position so that it cannot move away from being parallel so long as weight is applied on the ladder. If the shoe is on an extension, as the shoe slides up, it engages a safety bar that prevents release of the extension.

摘要： Improvements to the leg extension of an adjustable ladder leveler and, more generally, improvements to ladder legs. A shoe with fastener holes to reduce leg slippage. A shoe with a claw that folds to be parallel to the ladder leg and then slides upward with respect to the leg thereby becoming locked into position so that it cannot move away from being parallel so long as weight is applied on the ladder. Increased length and modified shape on the distal ends of control levers on the extendable leg ladder leveler so that the levers can be operated with a foot and do not require hand operation.
摘要翻译：改进了可调梯度矫直机的腿部延伸，更一般地，改进了梯腿。具有紧固件孔的鞋，以减少腿部滑动。具有爪的折叠的鞋与折叠脚平行，然后相对于脚向上滑动，从而被锁定到位，使得只要重量施加在梯子上，它就不能远离平行移动。在可伸缩的腿梯整平器上的控制杆的远端上增加长度和改进的形状，使得杠杆可以用脚操作，并且不需要手动操作。

摘要： A shoulder pad or shoulder cushion that can be affixed to the outside face of any ladder rail, regardless of shape, size, length, or material. One face of the pad is made to allow for easy and quick permanent attachment to the rail by way of self-adhesive, double-stick tape or other adhesive that enables the installer to simply and quickly affix the pad to the ladder in a matter of just a few seconds. The same side is hollowed out, or routed out, to allow ladder rung protrusions, rivets, or rung attachment plates to remain recessed inside the shoulder pad without interference to the adhesive edges of the pad. The hollow may be formed by the protrusion pushing into a thin layer of soft material of lower resilience than an adhered thicker layer.
摘要翻译：无论形状，尺寸，长度或材料如何，都可贴在任何梯子轨道的外表面上的肩垫或肩垫。制造垫的一个面使得通过自粘，双面胶带或其他粘合剂容易且快速地永久性地附接到轨道，使得安装者能够简单快速地将垫粘贴到梯子上只需几秒钟。相同的一侧被挖空或被排出，以允许梯子梯级突起，铆钉或梯级附接板在肩垫内保持凹陷，而不会干扰垫的粘合剂边缘。中空部可以通过突出部形成为比粘附的较厚层更低回弹力的柔软材料的薄层形成。
