Bed sheet with tensioning weight

Abstract

A bottom bed sheet assembly for a mattress that includes a primary textile panel and a rigid weight bar. The primary textile panel includes a main portion adapted to be placed over a top surface of the mattress. A foot end flap adapted to be draped beside a foot end of the mattress. A right-side flap and left-side flap are adapted to be draped beside right and left sides of the mattress. A head end flap adapted to be draped beside a head end of the mattress. The head end flap includes a pocket extending transversely across the head end flap at a lower end of the head end flap. The rigid weight bar is assembled into the pocket to apply tension to the primary textile panel in response to gravity acting on the rigid weight bar.

         8 . The assembly of  claim 1  wherein the rigid weight bar is an elongated planar blade having an upper edge, a lower edge, an inner surface and an outer surface, wherein the inner surface and the outer surface are wider than the upper edge and the lower edge. 
     
     
         9 . The assembly of  claim 1  further comprising:
 a textile sleeve that receives the rigid weight bar, wherein the textile sleeve and weight bar are inserted into the pocket through an opening on one end of the pocket, and the textile sleeve and weight bar are removed from the pocket through the opening to launder the primary textile panel. 
 
     
     
         10 . The assembly of  claim 1  wherein the rigid weight bar is a steel bar having a corrosion resistant coating. 
     
     
         11 . The assembly of  claim 1  wherein the foot end flap is sewn to the right-side flap at a foot end right corner of the mattress, and wherein the foot end flap is sewn to the left-side flap at a foot end left corner of the mattress. 
     
     
         12 . The assembly of  claim 11  wherein the head end flap is sewn to the right-side flap at a head end right corner of the mattress, and wherein the foot end flap is sewn to the left-side flap at a head end left corner of the mattress. 
     
     
         13 . The assembly of  claim 11  wherein the foot end flap, the right-side flap and the left-side flap each include an upper portion and a lower portion, wherein only the upper portions of the right-side flap and foot end flap are sewn together and wherein only the upper portions of the left-side flap and foot end flap are sewn together. 
     
     
         14 . The assembly of  claim 13  wherein the lower portions are adapted to be selectively tucked under the mattress. 
     
     
         15 . The assembly of  claim 13  wherein the lower portions are adapted to selectively hang below the upper portions below the mattress. 
     
     
         16 . A bottom bed sheet assembly for a mattress comprising:
 a primary textile panel including a main portion adapted to be placed over a top surface of the mattress, a foot end flap adapted to be draped beside a foot end of the mattress, right and left-side flaps adapted to be draped beside right and left sides of the mattress, wherein the foot end flap is sewn to the right-side flap at a foot end right corner of the mattress, and wherein the foot end flap is sewn to the left-side flap at a foot end left corner of the mattress, and a head end flap adapted to be draped beside a head end of the mattress, the head end flap having a pocket extending transversely across the head end flap at a lower end thereof, wherein the head end flap includes an extension panel sewn to an upper portion of the head end flap, and wherein the pocket is provided in the extension panel; and   a rigid weight bar assembled into the pocket applying tension to the primary textile panel in response to gravity acting on the rigid weight bar.   
     
     
         17 . The assembly of  claim 16  wherein the head end flap is sewn to the right-side flap at a head end right corner of the mattress, and wherein the foot end flap is sewn to the left-side flap at a head end left corner of the mattress.
