  • Anti-wrap device for swing set
    Patent number: 6123480
    Abstract: A device (10) for preventing a swing from being wrapped over a crossbar (18) of a swing set includes a base (12) and a sleeve (14) rotatably carried by the base (12). The base (12) includes a pair of collars (20) that each have a seat portion (22) bounded by a shoulder (26) at one edge. The collars (20) are attached to the crossbar (18) so that the seat portions (22) abut and cooperate to form a seat (42) that is bounded by the shoulders (26). The sleeve (14) rides on the seat (42) between the shoulders (26). The sleeve (14) is non-concentric and includes a tab (60) that angularly extends radially outwardly from the sleeve (14). The tab (60) has a hole (62) that accepts a bolt (64) that connects a chain (16) of the swing to the device (10).
