  • Patent number: 4872632
    Abstract: The disclosed apparatus (10) for suspending articles (14) from an overhead member (12) includes an elongated support member (20) attachable to the overhead member (12), first and second pulleys (22, 34) supported by the support member (20), an abutment (28) radially spaced from the first pulley (22), and a pivoting lock member (30) coaxial with and operably independent from the first pulley (22). A cord (32) passes over the first pulley (22) inwardly of the abutment (28) and extends further over the second pulley (34). One end of the cord (42) which is proximal to the second pulley (34), is attachable to an article (14) to be supported from the cord (32, 42). The cord (32) is normally freely movable over the pulleys (22, 34) to allow the height of a suspended article (14) to be adjusted, but may be restricted from movement in one direction by clamping engagement of the cord (32) between the lock member (30) and the abutment (28), thereby fixing the height at which an article (14) is suspended.
