Description

  The present invention relates to a sheet attached to a mattress.

  Conventionally, so-called box sheets, in which a gusset adapted to the thickness of a mattress is formed, are generally used as sheets to be attached to a mattress, by three-dimensionally stitching four corners of a cloth.

  Usually, the box sheet has an opening formed on the bottom side, and rubber is inserted through the periphery of the opening so as to wrap around the entire mattress.

However, the box sheets described above have the following problems in terms of work efficiency at the time of attachment.
That is, when attaching the box sheet to the mattress, the worker performs an operation of laying the periphery of the opening on the bottom surface of the mattress. This work is performed on each side of the mattress, and it is also necessary to adjust the position for uniform attachment. For this reason, the worker performs mounting work while going around the bed, and the working efficiency is extremely deteriorated.

  In particular, since sheets are frequently replaced in accommodation facilities and nursing homes, there has been a strong demand for the development of sheets that can be easily replaced with mattresses.

  In order to solve such problems, Patent Document 1 and Patent Document 2 have a sheet constructed by cutting four corners of one substantially rectangular cloth and providing an attaching / detaching means near the cut portion. Have been described.

  However, since the sheets described in Patent Document 1 and Patent Document 2 are not processed at all at the peripheral edge, fraying of the yarn occurs. In addition, since all four corners are cut at right angles, stress concentrates on the corners at the time of mounting work and the like, and cracks easily occur.

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

  The present invention has been made in view of the above-described actual situation, and an object thereof is to provide a sheet which can be easily attached and detached with respect to a mattress and which suppresses aging deterioration due to repeated use.

In order to solve the above problems, the present invention is
A substantially rectangular sheet body, a pair of short side ear portions provided on both short sides of the sheet body, and a pair of long side ear portions provided on both long sides of the sheet body,
The short side ear portion and the long side ear portion are characterized in that an edge portion thereof is subjected to bending processing.

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

In a preferred form of the invention:
The sheet body has an inwardly curved curved edge at at least one corner,
The short side ear has a short side edge extending towards 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 may be smoothly connected.

  With such a configuration, it is possible to disperse the stress concentration on the corners of the sheet body and to prevent the occurrence of cracks from the corners.

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

  With such a configuration, it is possible to prevent the occurrence of fraying of the yarn at the curved edge, to improve the strength, and to make the occurrence of cracks from the four corners of the sheet main body less likely to occur.

  A preferred embodiment of the present invention is characterized in that it has a gusset portion in which the short side edge and the long side edge are fixed.

  With such a configuration, when the sheet is attached to the mattress, even if a strong external force is applied to the sheet, the adhered portion is hooked to the corner of the mattress, which causes the sheet to be dislodged from the attachment position or from the mattress. It becomes possible to suppress unexpected detachment.

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

  With such a configuration, it is possible to easily realize a worn state without wrinkles on the surface when worn on a mattress.

  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.

  With such a configuration, when the sheet is attached to the mattress, it is possible to eliminate the upward protrusion of the four corners, and it is possible to achieve an excellent wearing appearance.

  In a preferred embodiment of the present invention, the short side ear portion and the long side side ear portion have connection means which are detachably connected to each other.

  With such a configuration, the sheet can be easily attached to and detached from the mattress.
