Adjustable mattress cover

Abstract

An adjustable sheet having a draw string around the perimeter of the sheet. The sheet will be large enough to fit over a standard mattress, and then the draw string can be pulled so the perimeter of the sheet is tightly secured under the mattress.

I claim: 
     
         1 . An adjustable mattress cover ( 10 ), comprising:
 a sheet portion ( 20 ) having a perimeter ( 40 ) and a draw string channel ( 50 );   a draw string ( 30 ) slidably disposed within said draw string channel ( 50 ); whereby said sheet portion ( 20 ) can be draped over a mattress ( 80 ) and the draw string ( 30 ) can be pulled to tighten said perimeter ( 40 ) under the mattress ( 80 ) to secure said sheet portion ( 20 ) under the mattress ( 80 ).   
     
     
         2 . The apparatus of  claim 1 , further comprising:
 a locking means ( 70 ) slidably disposed on said draw string ( 30 ) to retain said draw string ( 30 ) taught under the mattress ( 80 ).   
     
     
         3 . The apparatus of  claim 1 , further comprising:
 a pocket ( 60 ) disposed on said sheet portion ( 20 ) to receive a portion of said draw string ( 20 ).   
     
     
         4 . An adjustable mattress cover ( 10 ), comprising:
 a sheet ( 20 ) having a draw string ( 30 ) slidably disposed within said sheet ( 20 ), said sheet ( 20 ) having a draw string aperture ( 90 );   a fastener ( 70 ) slidably disposed on said draw string ( 30 ) that can lockingly engage with the draw string ( 30 ).   
     
     
         5 . The apparatus of  claim 4 , wherein said sheet ( 20 ) is large enough to be secured to a mattress. 
     
     
         6 . An adjustable mattress cover ( 10 ), comprising:
 a sheet portion ( 20 ) having a perimeter ( 40 ) and a draw string channel ( 50 );   at least one draw string ( 30 ) slidably disposed within said draw string channel ( 50 ); whereby said sheet portion ( 20 ) can be draped over a mattress ( 80 ) and the draw string ( 30 ) can extend away from said sheet portion ( 20 ) in at least one location via a draw string aperture ( 90 ) so that at least one draw string can be pulled to tighten said perimeter ( 40 ) under the mattress ( 80 ) to secure said sheet portion ( 20 ) under the mattress ( 80 ).   
     
     
         7 . The apparatus of  claim 6 , further comprising:
 a locking means ( 70 ) slidably disposed on said draw string ( 30 ) to retain said draw string ( 30 ) taught under the mattress ( 80 ).   
     
     
         8 . The apparatus of  claim 6 , further comprising:

         9 . An adjustable mattress cover ( 10 ), comprising:
 a sheet ( 20 ) having a draw string ( 30 ) slidably disposed within said sheet ( 20 ), said sheet ( 20 ) having a draw string aperture ( 90 );   a fastener ( 70 ) slidably disposed on said draw string ( 30 ) that can lockingly engage with the draw string ( 30 ).   
     
     
         10 . The apparatus of  claim 9 , wherein said sheet ( 20 ) is large enough to be secured to a mattress.
