摘要： Ladders and ladder components are provided including a rung assembly that provides an alert to a user of the ladder that they are standing on a particular rung or step. In one example, the lower most rung or step of a ladder includes a rung assembly having an alert mechanism. The alert mechanism may provide an audible and/or other sensory alert to a user when they step on the rung assembly so that the user recognizes their position relative to the ground or supporting surface. In one embodiment, the rung assembly is configured such that a front edge remains in a constant or fixed position relative to the rails to which it is coupled so that a user can rely on a fixed or constant position of the front edge of the assembly when climbing or descending the ladder.

摘要： A ladder is provided having a base section and a fly section slidably coupled with the base section. The base section includes a first pair of spaced apart rails and a first plurality of rungs extending between and coupled to the first pair of spaced apart rails. The fly section includes a second pair of spaced apart rails and a second plurality of rungs extending between and coupled to the second pair of spaced apart rails. The various rungs may be coupled with their associated rails in an offset relationship such that they are not centered along a longitudinal center axis line of the rails. A rung lock device may be used which includes an arm pivotally coupled with the base section and configured to selectively engage various rungs of the second plurality of rungs to maintain the fly section in a desired position relative to the base section.
摘要翻译：提供了一种梯子，其具有基部和与该基部可滑动地联接的飞行部。基部包括第一对间隔开的导轨以及在第一对间隔开的导轨之间延伸并联接至第一对间隔开的导轨的第一多个梯级。所述飞行部分包括第二对间隔开的导轨和第二多个梯级，所述第二多个梯级在所述第二对间隔开的导轨之间延伸并联接到所述第二对间隔开的导轨。各个梯级可以以偏移关系与它们相关联的轨道联接，使得它们不沿着轨道的纵向中心轴线对中。可以使用横档锁定装置，其包括与所述基部可枢转地联接并且被构造成选择性地接合所述第二多个梯级中的各梯级以将所述飞行部相对于所述基部保持在期望位置的臂。
