Reversible bed frame

Abstract

A reversible bed frame with a horizontal and an inclined position is disclosed herein. Its angular disposition is transformed from horizontal to inclined by turning it upside down. The bed frame preferably comprises multiple load-bearing elements (140) that are connected to and between two side rails (110) thus providing a top surface (150) and a bottom surface (210) of rectangular shape, with both surfaces able to withstand a load. Elevating members (120, 130) provide elevation for both surfaces. In accordance with one embodiment, the elevating members are of varying height so that the top surface is horizontal when facing upwards and the bottom surface is inclined when facing upwards. In accordance with another embodiment, different measurements and positioning of the load-bearing elements provide a horizontal top surface and an inclined bottom surface.

What is claimed is: 
     
         1 . A bed frame, comprising:
 two side rails;   one or more load-bearing elements; and   two or more elevating members;   wherein the load-bearing elements being rigidly connected to and between the side rails, thus providing a top surface and a bottom surface of rectangular shape and of sufficient resistance to withstand a load, for example of a mattress and a human;   wherein the bottom surface is parallel to the upper surface;   wherein the elevating members being rigidly connected to the side rails, and extending above the top surface and below the bottom surface;   wherein each elevating member having a predetermined height, such that the top surface is horizontal when facing upwards, and the bottom surface is inclined when facing upwards   whereby a human may transform the angular disposition of the bed frame from horizontal to inclined by turning it upside down.   
     
     
         2 . The bed frame of  claim 1  wherein the load-bearing elements are rigidly connected to the side rails by means of mortises and tenons. 
     
     
         3 . The bed frame of  claim 1  wherein the bottom surface, when facing upwards, is inclined at a predetermined angle from about 2 degrees to about 7 degrees. 
     
     
         4 . A bed frame, comprising:
 two side rails;   one or more load-bearing elements; and   two or more elevating members;   wherein the load-bearing elements being rigidly connected to and between the side rails, thus providing a top surface and a bottom surface of rectangular shape and of sufficient resistance to withstand a load, for example of a mattress and a human;   wherein the bottom surface is inclined relative to the top surface;   wherein the elevating members being rigidly connected to the side rails, and extending above the top surface and below the bottom surface;   whereby a human may transform the angular disposition of the bed frame from horizontal to inclined by turning it upside down.   
     
     
         5 . The bed frame of  claim 4  wherein the load-bearing elements are rigidly connected to the side rails by means of mortises and tenons. 
     
     
         6 . The bed frame of  claim 4  wherein the bottom surface is inclined at a predetermined angle from about 2 degrees to about 7 degrees.
