摘要

A portable support structure is disclosed having a horizontal member and single upright supports suitably connected at each end thereof at an angle of less than 90 DEG so that the upright supports are directed inwardly. Without additional bracing, this support structure is able to withstand applied forces to the horizontal bar and exhibits a high degree of stability in use. The support is particulary suitable for ballet barres and gymnastic equipment.
