US Patent 10517412 Sheet bed tightener

A cord with an outer fabric covering over a sheath and draw string is used to secure a sheet to a bed. The cord has a series of clips attached there-to by a second cord or by direct attachment. The clips are in turn removably attachable to edges of a sheet. One then tightens the draw string, reducing the length of the cord, and continues to do so until the sheet is pulled to a bottom side of the mattress. In this manner, the sheet ends are beneath the mattress and tightened thereto by the cord. The cord further snaps to itself, in embodiments of the disclosed technology, to form a closed loop around the bed.
