Portable ballet bar exercise device

The invention discloses a portable ballet bar exercise device. Multiple embodiments of a portable exercise bar are disclosed. Fixed ballet bars are standard equipment in dance studios and exercise facilities. Ballet bars are used by dancers and persons exercising to keep their balance while engaging in stretching, dancing, cardio-vascular, weight-strengthening, and other exercise activities. The assignee of this application is an innovator in free-standing ballet bar exercise devices and previously obtained United States patents, which are incorporated by reference herein. Prior art free-standing ballet bars sometimes could be relatively heavy and cumbersome to use. In addition, they often were somewhat difficult to store because they could not be easily collapsed into a compact configuration.
