Patent attributes
A bed rail assembly includes a joint device connecting two top tubes, a pair of corner members mounted to free ends of the top tubes, two vertical tubes mounted to and depending from the corner members, and a pair of knuckle devices mounted to lower ends of the vertical tubes. Horizontal support tubes extend from the knuckle devices in a direction substantially normal to a plane defined by the top tubes and the vertical tubes. Extensions project from the knuckle devices to receive and fix support tube thereby forming a rectangular frame onto which a cover is attached to shield the frame. Each knuckle device includes a movable member movably connected to a base of the knuckle device to allow collapse of the bed rail. A Y-shaped belt and an L-shaped retention member are used to secure the bed rail assembly to a mattress.
