    摘要： The present invention relates to ladders and, more particularly, various configurations of ladders including straight and extension ladders, as well as to methods relating to the use and manufacture of such ladders. In accordance with one embodiment of the present invention, a ladder is provided that includes a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. The ladder also includes a pair of lateral support members, wherein each support member is selectively displaceable in a lateral direction relative to an associated rail. Additionally, the ladder includes a pair of adjustable legs, each leg having a first end slidably coupled to an associated rail of the first pair of spaced apart rails and being slidably coupled to an associated lateral support member.

    摘要： An extensible, self locking platform includes a first assembly having a first plurality of substantially parallel longitudinally extending members and a second assembly having a second plurality of substantially parallel longitudinally extending members. The first and second assemblies are longitudinally, slidably coupled with each other. The platform may also include one or more catch devices. In one embodiment, at least one catch member is pivotably coupled to the first assembly with an associated stop member. The stop member is configured to maintain a rotation of the at least one catch member at less than a full revolution such that when the catch member is being abutted against an elevated support structure and the platform is being laterally displaced relative thereto, the catch member will also abut the stop member and prevent further displacement of the platform relative to the elevated support structure.

    摘要翻译： 可伸展的自锁平台包括具有第一多个基本上平行的纵向延伸构件的第一组件和具有第二多个基本平行的纵向延伸构件的第二组件。 第一和第二组件彼此纵向地，可滑动地联接。 平台还可以包括一个或多个捕获装置。 在一个实施例中，至少一个止动构件可枢转地联接到具有相关联的止动构件的第一组件。 止动构件被构造成保持至少一个止动构件的旋转小于全旋转，使得当夹紧构件抵靠升高的支撑结构并且平台相对于其横向移位时，捕获构件将 还邻接止动构件并防止平台相对于升高的支撑结构的进一步移位。
