摘要： Ladders and related methods of using and manufacturing stepladders are provided. In one embodiment, a stepladder is provided that comprises a first assembly hingedly coupled with a second assembly. The first assembly has a pair of spaced apart rails pivotally coupled with one or more rungs. The second assembly includes a pair of space apart rails with one or more bracing members extending therebetween. The first assembly and second assembly are configured to be displaced relative one another such that the stepladder is selectively positionable between a first, deployed state and a second, collapsed state. Upon rotation of the two assemblies relative to one another into a stowed condition, components of the second assembly engage undersurfaces of the rungs effecting rotation of at least a portion of each rung relative to the rails of the first assembly.

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：梯子被设置成具有基部和与该基部可滑动连接的飞行部分。基部包括第一对间隔开的轨道和在第一对间隔开的轨道之间延伸并耦合到第一对间隔开的轨道的第一多个梯级。飞行部分包括第二对间隔开的轨道和在第二对间隔开的轨道之间延伸并耦合到第二对间隔开的轨道的第二多个梯级。各个梯级可以以其偏移关系与其相关联的轨道联接，使得它们不沿着轨道的纵向中心轴线居中。可以使用梯级锁定装置，其包括与基部枢转地联接的臂，并且构造成选择性地接合第二多个梯级的各个梯级，以将飞行部分保持在相对于基部的期望位置。

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.
摘要翻译：提供了梯子和梯子部件，包括梯级组件，其向梯子的用户提供他们正在特定梯级或台阶上的站立的警报。在一个示例中，梯子的最下层或梯级包括具有警报机构的梯级组件。警报机构当他们踏上梯级组件时可以向用户提供听觉和/或其他感官警报，以便使用者识别出相对于地面或支撑表面的位置。在一个实施例中，梯级组件被构造成使得前边缘相对于其所联接的轨道保持在恒定或固定的位置，使得用户可以依靠组件的前边缘的固定或恒定位置，攀登或下降梯子。
