Abstract: A bed frame wherein the side rail and/or cross rails are fully encased in plastic shields. A plastic shield or shields cover the entire cross sectional area of the side and cross rails so that the side rail and cross rails are easy to handle and esthetically pleasing. The system avoids the need for a person to handle cold, sometimes dirty, steel and the cross and side rails may be T-shaped or L-shaped angle irons, or other configurations and covered with plastic shields.

Abstract: A bed frame comprising T shaped side rails provide support for a box spring and mattress. A leg assembly is affixed to the bed frame and is affixed to the side rail and to the cross rails for better strength of connection. The use of T-shaped side rails provides more resistance to twisting and bowing and thereby more resistant to damage a leg or other structural component of the bed frame from moving the bed frame across the floor. The use of the T-shape cross section side rails enables the overall bed frame to support more weight with less deflection than the convention L-shaped side rails. There are also headboard and footboard brackets that take advantage of the greater height of the vertical flange of the side rail to have affixation means, such as rivets, that are further spaced apart to provide a more rigid connection between the brackets and the side rails.

Abstract: A bed frame comprising T-shaped side rails provides support for a box spring and mattress.

Abstract: The bed with automatic mattress lifting system is a bed with a frame and an internal drive system for raising a mattress above the frame, allowing the user to easily change the sheets or other bed coverings. The mattress rests on a mattress supporting platform, which, in the lowered position, is received within the frame. In operation, driven motion of an internal rod caused by a drive system located within the frame generates rotation in a lever arm. The lever arm is secured to a shaft that extends across the frame, and rotation of the shaft causes a pair of supports to rotate. Upper ends of the supports are joined to a lower surface of the mattress supporting platform, thus driving upward movement of the mattress supporting platform. The sheets cover both the mattress and the platform, allowing the sheets to be changed without having to manually lift the mattress.

Abstract: A modular bed frame has ladder-like side frames with upper and lower side rails, and ladder-like end frames with upper and lower rails. The side and end frames telescopingly attach to the ends of upper and lower rounded corner rails on separate corner assemblies at the four corners of the assembled foundation.

These fittings support upwardly opening tubular sleeves that receive right angle corner connectors on the ends of spaced apart and parallel horizontal slats that traverse the bed frame from end to end when assembled by a user. Separate bed-elevating assemblies positioned at or near the corner connector assemblies elevate the assembled foundation above the floor.

Abstract: A comprehensive means of providing protection to a bed frame by covering various locations about the bed frame with plastic shields. The plastic shields are adapted to enclose the various locations about the bed frame including the ends of side rails, the junction of side rails and cross members, leg assemblies and the side rails themselves. The shields comprise a pair of housings joined together with a living hinge such that the free ends can be affixed together to surround and enclose the various locations where sharp edges are present. The use of the shields provides overall protection to all of the locations where there may be sharp edges that could harm a person striking the location and thus there is a comprehensive approach to full protection of the bed frame.

Abstract: The bed with automatic mattress lifting system is a bed with a frame and an internal drive system for raising a mattress above the frame, allowing the user to easily change the sheets or other bed coverings. The mattress rests on a mattress supporting platform, which, in the lowered position, is received within the frame. In operation, driven motion of an internal rod caused by a drive system located within the frame generates rotation in a lever arm. The lever arm is secured to a shaft that extends across the frame, and rotation of the shaft causes a pair of supports to rotate. Upper ends of the supports are joined to a lower surface of the mattress supporting platform, thus driving upward movement of the mattress supporting platform. The sheets cover both the mattress and the platform, allowing the sheets to be changed without having to manually lift the mattress.

Abstract: An adjustable bed frame assembly includes a clamp which fits with two aligned and overlapping frame rails, including horizontal and vertical legs of the frame rails, to enable relative adjustment of the frame rails and to fix the bed frame at a set dimension. A leg mount extends from the clamp with a structure for mounting a vertical leg for additional elevation and support of the bed frame. The vertical extent of the leg is also adjustable by interconnection with one or more extension pieces. The configuration of the clamp and the leg mount both stiffens the bed frame and provides a very rigid support member for the bed frame. The leg mount can be formed from a single piece of metal with an open seam, and the extension pieces can be formed from a single piece of metal with an open seam.
