发明名称 Device for attaching a sheet to a mattress
摘要 A device for attaching a sheet to a mattress comprises an elongate, inextensible strap having first and second opposite ends. The strap is positionable under the mattress across a corner thereof with the first and second opposite ends projecting beyond the two edges respectively. A first fastener is attachable to the strap at the first end thereof and comprises a plate member and a stud. The plate member has two opposite sides and is formed with an elongate opening extending therethrough. The opening has two regions, one of which is narrower than the other. The stud has a base portion, a head portion and a neck portion. The neck portion connects the base portion and the head portion. The base portion is sized to pass through the wider region of the opening, but both the head portion and the base portion are too large to pass through the narrower region. The neck portion is sufficiently narrow to enter the narrower region of the opening. A second fastener is attachable to the strap at the second end thereof.
