Modular foundation assembly for beds

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. The insides of the side frames carry tubular upright fittings for increasing vertical rigidity. These fittings also provide 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 upright rigid legs with feet on the bottom are slidably attached to downwardly opening tubular sleeves on the underside of the assembled frame structure to elevate the assembled bed foundation above the floor.

       8 . Apparatus according to  claim 7  including separate upright rigid metal leg members; and separate rigid leg connectors rigidly affixed to selected ones of the first bracing members and configured to slidably receive corresponding ones of the leg members.  
   
   
       9 . Apparatus according to  claim 7  in which the slat connectors are tubular and positioned to slidably receive correspondingly configured side frame connection members at opposite ends of the slats.  
   
   
       10 . Apparatus according to  claim 7  in which the upper corner connectors and lower corner connectors each include at least one tubular sleeve member at their ends for slidably engaging an end portion of a corresponding side member or end member.  
   
   
       11 . Apparatus according to  claim 8  in which selected ones of the first bracing members include both a slat connector on an upper portion thereof and a leg connector on a lower portion thereof.
