发明名称 Doorway mounted horizontal bar
摘要 The horizontal bar includes tubular members freely telescopically interconnected having lateral extending ends depending to outward facing U-shaped members having sufficient width to be disposed about the respective sides of a doorway, and to have frictional engagement therewith. A pivotal link is attached to the base of each U-shaped member and is slidably engaged with a respective wedge-shaped receiving bracket at each side of the doorway. The pivotal links may be engaged with the respective receiving brackets in a depending orientation for a lower position of the horizontal bar or may be engaged with the brackets in an upstanding orientation for a higher position of the horizontal bar.
