US Patent 7387599 Massaging body-gym apparatus

A massaging body-gym apparatus is composed of a rod, at least two rollers, two positioning sleeves, two sealing covers and an elastic rope. A positioning device is installed in the roller, composed of a pair of half positioning bases and a positioning bar. The positioning sleeve has a blocking disc bored with a restricting hole for inserted by the positioning bar. With the positioning bar inserted in or separated from the restricting hole of the positioning sleeve, the roller can be positioned immovably or released to rotate freely, so that, combined with different postures, various parts of a human body can be exercised or massaged. In addition, the present invention is small and light, handy for carrying.
