发明名称 Kit for enabling guy-wire guards to spin
摘要 A guy-wire guard support apparatus prevents personal injury or damage resulting from climbing or playing on guy wires by causing the guard to spin freely upon contact. The apparatus consists of a collar-like component and a cup-like component both of which contain a free-wheeling element such as ball bearings. By mounting or seating a guard upon or within at least one of each component, the guard can easily spin about its axis, thereby hindering attempts to grasp or stand on it. Another embodiment consists of multiple collars attached to the wire and circular shoulders inside the guard resting on rollers in the top of each collars.
