  • Patent number: 4099289
    Abstract: An elongated rod is provided including opposite ends and a pair of end members are removably rotatably mounted on the opposite ends of the rod. The opposite rod ends include first endwise outwardly facing abutment friction surfaces and the end members include second abutment friction surfaces opposing and frictionally engaged with the corresponding first friction surfaces. An elongated flexible tension member is anchored at its opposite ends to the end members and is spiraled about the rod intermediate the end members in a tensioned condition, whereby the tension member retains the end members on the opposite ends of the rod and the frictional engagement between the first and second friction surfaces prevents relative rotation of the end members relative to the rod and thereby maintains the tension member in a spiraled condition about the rod. A cleaning structure in the form of a rag, brush head, sponge, etc.
