Abstract

A bed cover adjusting apparatus comprising mattress clamps which are adjustable for use with a range of mattress thicknesses and a bed cover engaging rod positioned below a bed cover, and which is length extensible corresponding to a range of mattress widths. An engagement positioning device pivots the engaging rod over a desired angular range, and a position controller is enabled for receiving and acting on wave energy signals of remote origin. The engagement positioning device is pivotally joined with the clamps for movement as driven by the positioning device under commend of the position controller.

What is claimed is:  
     
         1 . A bed cover adjusting apparatus comprising a mattress clamping means adjustable for receiving a range of mattress thicknesses in clamped relationship; a bed cover engaging means, for positioning below a bed cover, and length extensible corresponding to a range of mattress widths, an engagement positioning means pivotal over an angular range, and a position control means enabled for receiving and acting on wave energy signals of remote origin; the engaging means pivotally joined with the clamping means for movement thereabout as driven by the positioning means under commend by the control means.  
     
     
         2 . The apparatus of  claim 1  wherein the mattress clamping means comprises dual upper L-shaped brackets and lower L-shaped bracket.  
     
     
         3 . The apparatus of  claim 2  further comprising a bracket spacing strap, the spacing strap joining the L-shaped brackets at opposing strap ends thereof for holding the lower L-shaped brackets at a spacing corresponding to a mattress width.  
     
     
         4 . The apparatus of  claim 1  wherein the bed cover engaging means comprises a pair of support arms and a cover lift rod, each one of the support arms pivotally engaged with one of the upper L-shaped brackets at a proximal end of the support arm and engaged at one end of the cover lift rod at a distal end of the support arm, such that as the pair of support arms pivot about the upper L-shaped brackets from a lowered position to a raised position, the cover lift rod moves through an arc to lift the bed cover resting thereon.  
     
     
         5 . The apparatus of  claim 4  wherein the cover lift rod comprises plural segments in linear telescoping relationship.  
     
     
         6 . The apparatus of  claim 1  wherein the engagement positioning means comprises dual electric motors each pivotally joined with one of the upper L-shaped brackets and each engaging a threaded shaft enabled for advancing and retracting with rotational motion of each of the electric motors in a first and second rotational senses respectively, and each of the threaded shafts pivotally engaging one of the support arms of the bed cover engaging means so as to enable angular positioning thereof.  
     
     
         7 . The apparatus of  claim 1  wherein the position control means comprises a power supply interconnected with the electric motors for providing electrical power thereto, a remote control unit interconnected for sending control signals to a controller adapted for directing motor rotational sense and for enabling and disabling power delivery to the electrical motors for starting and stopping the raising of the bed covers.
