Patent ID: 8745787

Claim:
A sheet anchoring system configured to restrain the periphery of a sheet on a bed, the sheet anchoring system comprising, a plurality of pivotable clips each having a first end and a second end, the first end comprising engaging friction surfaces configured to grasp between the surfaces a portion of the periphery of the sheet, the second end comprising engaging surfaces configured to be forced into engagement when in use by the weight of a mattress on top of the second end when the second end is placed between the mattress and a box spring below the mattress; wherein the first end is offset from the second end such that the weight of the mattress on the second end increases a grasping force on the first end; the pivotable clips configured to securely restrain movement of the sheet periphery during use without the need for a spring or other force-biasing mechanism to maintain the friction surfaces of the first end in engagement with the sheet therebetween, the friction surfaces comprising a material having a coefficient of friction sufficient to restrain movement of the sheet from between the surfaces of the first end when in use.
