  However, since the sheets described in Patent Literature 1 and Patent Literature 2 are not processed at all at the periphery, fraying of the yarn occurs. In addition, since the four corners are cut at right angles, stress is concentrated on the corners during mounting work, and cracks are easily generated.

  For this reason, the sheets described in Patent Document 1 and Patent Document 2 are severely aged and are not suitable for repeated use.

  This invention is made | formed in view of the above actual conditions, and makes it a subject to provide the sheet which can perform the attachment or detachment operation | work with respect to a mattress simply, and suppresses aged deterioration by repeated use.

In order to solve the above problems, the present invention provides:
A substantially rectangular sheet main body, a pair of short side ears provided on both short sides of the sheet main body, and a pair of long side ears provided on both long sides of the sheet main body,
The short side ears and the long side ears are characterized by being edged.

  According to the present invention, it is possible to prevent the yarn from fraying because the edge portions of the short-side ear portion and the long-side ear portion are subjected to the overburden processing.

In a preferred form of the invention,
The sheet body has a curved edge that curves inward at at least one corner,
The short side ear has a short side edge extending toward the curved edge,
The long side ear has a long side edge extending toward the curved edge,
The curved edge, the short side edge, and the long side edge are smoothly connected.

  By adopting such a configuration, it is possible to disperse the stress concentration at the corner of the sheet main body and to prevent the occurrence of cracks from the corner.

  In a preferred embodiment of the present invention, the curved edge portion is subjected to an overwork process.

  By adopting such a configuration, it is possible to prevent the fraying of the yarn at the curved edge portion, to improve the strength, and to further prevent the occurrence of cracks from the four corners of the sheet body.

  In a preferred embodiment of the present invention, the present invention has a gusset portion in which the short side edge and the long side edge are fixed.

  By adopting such a configuration, even when a strong external force is applied to the sheet when the sheet is mounted on the mattress, the fixed portion is caught at the corner of the mattress, so that the sheet mounting position shifts from the mattress. It is possible to suppress unexpected detachment.

  In a preferred embodiment of the present invention, a plurality of the gusset portions are formed along either the short side direction or the long side direction of the sheet main body.

  By adopting such a configuration, it is possible to easily realize a mounting state without a wrinkle on the surface when the mattress is mounted.

  In a preferred embodiment of the present invention, at least one of the short side ear and the long side ear is configured separately from the sheet main body.

  By adopting such a configuration, when the sheets are mounted on the mattress, it is possible to eliminate the upward bulging of the four corners, and it is possible to achieve a mounting state with an excellent aesthetic appearance.

  In a preferred embodiment of the present invention, the short side ear and the long side ear have a connecting means for detachably connecting to each other.

  With such a configuration, it is possible to easily attach and detach the sheets to and from the mattress.
