    • A ladder is provided comprising a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. A pair of hooks are located such that each hook is positioned adjacent and upper end of an associated rail. A securing apparatus is coupled adjacent the upper end of the first pair of spaced apart rails. The securing apparatus includes a pair of spaced apart engaging members and may include a cross-member coupled therebetween. Each of the engagement members is pivotal with respect to an associated rail of the first pair of spaced apart rails. In one embodiment, the securing apparatus lacks any biasing members (e.g., springs or actuators) or locking members. The engagement members and hooks cooperatively encircle and overhead, generally horizontal support member to support and secure the ladder in a desired position.
    • 提供梯子,其包括第一对间隔开的轨道和多个梯级,梯道在第一对间隔开的轨道之间延伸并与第一对间隔开的轨道连接。 一对钩子定位成使得每个钩子定位在相关轨道的相邻和上端。 紧固装置在第一对间隔开的导轨的上端附近连接。 固定装置包括一对间隔开的接合构件并且可以包括联接在其间的横向构件。 每个接合构件相对于第一对间隔开的导轨的相关联的导轨是枢转的。 在一个实施例中,固定装置没有任何偏置构件(例如,弹簧或致动器)或锁定构件。 接合构件和挂钩协作地环绕并架设在大体上水平的支撑构件上,以将梯子支撑并固定在期望的位置。
