Abstract
A pair of side frames, formed of inverted U-shaped metal tubes and having horizontal brace members, are spaced apart and rigidly connected by crossed tubular members which pivotably engage the metal tubes of the side frame at their ends, one pair of tubular ends being detachable. An armrest pad is hingedly connected across the top of the side frames, such that the pad can be folded down and the side frames collapsed inwardly, after detachment of the crossed tubular members. One of the horizontal brace members supports a cylindrical holder for an oxygen bottle.
Claims5
An oxygen walker comprising:
- a pair of side frames disposed apart and formed of inverted U-shaped metal tubes having horizontal brace members adapted for supporting a source of oxygen, each of the side frames having a pair of vertically spaced apart connector means on the same side, with the connector means of one side frame being horizontally aligned with the connector means of the other side frame, said connector means comprising lower tubular projections in substantial alignment with the horizontal brace members and upper cylindrical projections;
- a pair of U-shaped tubular members, pivotably secured for relative rotational movement about their center portions and including one end adapted to be pivotably received in the tubular connectors on said side frames and adapted to be removably disposed over the cylindrical connectors on said side frames, whereby disengagement of the corresponding ends of said members from said cylindrical connectors, allows for folding of said side frames toward one another and unfolding and engagement of the corresponding ends of said members with said cylindrical projections provides a rigid structure.
