发明名称 Step assembly with a removable step for hollow poles and the like
摘要 There is provided a pole step assembly with a removable step for hollow poles and the like. The step assembly includes a mounting subassembly with a mounting stud and a mounting plate with inter-engaging flat surfaces that limit relative rotational movement of the mounting stud and mounting plate about the axis of the subassembly. A clamp is provided to limit radial movement of the subassembly relative to the pole. The mounting stud of the subassembly also may include a handle portion that captivates the components of the subassembly and facilitates ease of installation of the subassembly. The handle also may break away and be removed after installation of the subassembly. The step is mounted to the subassembly and may include flat surfaces that inter-engage with further flat surfaces on the mounting plate to limit rotation of the step about its longitudinal axis.
