摘要： A bed sheet stuffing device has an elongated thin flat shaft member and a clamp element attached on a leading end portion of the shaft member adapting the device for use in stuffing a corner of a bed sheet under a waterbed mattress. The shaft member and clamp element are both composed of resiliently flexible material and configured to be flexible about axes extending across their respective widths. The clamp clement has an outwardly flared guide lip at its forward end which together with the forward edge of the shaft member defines a slot normally closed at its front and sides but adapted to be forceably opened for receiving therethrough an edge of the bed sheet corner. A cavity is defined between the clamp element and shaft member aft of the lip is open at its opposite sides and closed and pivots at its rear end. The cavity at its forward end communicates with the slot. The clamp element can be attached to the top surface of the shaft member or can be attached to the bottom surface of the shaft with the curved portion extending into a rectangular aperture in the shaft member with the forward lip disposed below the leading edge of the shaft to form said slot. The clamp element is thereby adapted to receive and releasably hold the bed sheet edge and pull the same along as the shaft member is inserted alongside and under the mattress. The clamp member is also adapted to release from the bed sheet edge when the stuffing device is withdrawn from the mattress.
