ABSTRACT:
A collapsible bed rail includes two spaced upright rods having an upper end to which an upper corner joint is fixed and a lower end to which a lower corner joint is pivoted so as to allow the upright rods to be rotatable among an expanded position, a collapsed position and a rail open position. An upper horizontal rod comprised of two sections pivotally jointed to each other by means of an upper central joint is pivoted at two opposite ends thereof to the upper corner joints. A lower horizontal rod comprised of two sections pivotally jointed to each other by means of a knuckle joint structure is releasably fixed at two opposite ends thereof to the lower corner joints. A transverse bar extends from each of the lower corner joints in a direction substantially normal to the respective upright rod and the lower horizontal rod to be disposed and held under a matrix so as to mount the bed rail to the bed on which the matrix is placed. A resilient cover sheet member is arranged within the upper and lower horizontal rods and the upright rods.
