Description

  The present invention prevents the mattress from being soiled by covering the mattress used in hospitals, nursing homes or general households, giving the user a comfortable feeling of use, and preventing the user from developing epilepsy. It relates to a cover type sheet that can be.

  Mattresses used for beds in hospitals and nursing homes are covered with sheets in order to prevent dirt and soften the user's feel. In order to keep the sheets clean, the sheets are regularly replaced with new sheets, and when sheets become suddenly soiled, the sheets are replaced every day. However, it is physically burdensome for one nurse to lay a sheet of cloth on the lower side of the four sides of the mattress and wear it so that there are no wrinkles on the upper surface. There is a problem of poor efficiency. On the other hand, there is a problem that labor costs increase when two sheets of nurses exchange sheets.

  In view of this, a sheet has been proposed in which a belt-like body made of an elastic material is attached obliquely across two adjacent sides in the vicinity of each corner on the back side of the sheet. This laid sheet can be attached easily and firmly with elasticity simply by fitting the elastic band-like body 2 to the corner portion of the quilt using the elastic stretch (Patent Document 1).

  Moreover, it consists of towel cloth or plain woven cloth of a substantially rectangular shape in plan view, and forms bag-like insertion parts (6, 16) at both ends in the longitudinal direction of these cloths, and these insertion parts (6, 16) There has been proposed a bedding cover such as a mattress and a mattress in which both ends of a mattress and a mattress can be inserted, and these fabrics can be stretched at least in the longitudinal direction (Patent Document 2).

However, the bed sheet disclosed in Patent Document 1 is a belt-like body made of an elastic material provided at each corner of a square sheet, and is attached to both ends in the longitudinal direction of the bed sheet. The bedding cover disclosed in Patent Document 2 is In addition, the longitudinal ends of mattresses and mattresses are inserted into the bag-shaped insertion portions formed at least at both ends in the longitudinal direction of the substantially rectangular fabric in plan view. It is not the structure which hold | maintains a part reliably.
For this reason, both the bed sheet and the bedding cover have the disadvantage that the middle part in the longitudinal direction is loosened during use, and it is easy for wrinkles to occur, and because of this wrinkle, the user develops pressure ulcers. There is a disadvantage that it cannot be used.

  The present invention has been made by the inventor's earnest research in view of the above-mentioned drawbacks of the prior art. By combining a stretchable cloth material and a non-stretchable cloth material, mattress insertion / removal work is easy. Because it can be done quickly, it has excellent workability, and the mattress can be covered without any slack, including the middle part in the longitudinal direction, preventing wrinkles and drowning during use and preventing the development of pressure ulcers. An object of the present invention is to provide a cover-type sheet that can be used.

Means constituting the present invention for solving the above-described problem is that a sheet body made of a cloth material having elasticity in a 360-degree direction in a plan view includes an upper surface covering portion covering the upper surface of the mattress, and the upper surface covering portion. Subsequently, an end surface covering portion that covers both longitudinal ends of the mattress, a side surface covering portion that covers the lateral side surface of the mattress following the upper surface covering portion, and a lower surface that covers the lower surface edge of the mattress following the side surface covering portion It becomes a cover portion from those formed integrally, each of the four pressing fabric comprising a fabric material having a non-stretchable by organizing weft and warp, a hypotenuse parallel to the weft or warp, together Each of the pair of presser cloths covering the corners on both ends in the longitudinal direction of the mattress is formed by superimposing the tip sides on each other. State and heavy Portion sewed the one side to the end surface covering portions of the sheets body without sewing, by sewing the other side on the lower surface cover portion, the mattress housing portion inside, the mattress inserted on the lower surface A part of the lower surface covering portion can be expanded and contracted by forming an opening and sewing the pair of presser cloths to the lower surface covering portion while being spaced apart in the longitudinal direction of the sheet body.

The pair of presser cloths for sewing the other side to the lower surface covering portion along the longitudinal direction of the sheet main body may be arranged with their tips separated by about 12 to 13 cm.

Since the present invention is configured as described above, the following effects can be obtained.
(1) Cover type sheets are composed of a sheet body made of stretchable cloth material and a presser cloth made of non-stretchable cloth material. Since it doesn't get cramped, the onset of pressure sores can be prevented as much as possible.
(2) Since the mattress insertion / removal port is constructed so that a part of the lower surface covering portion of the sheet body extends and greatly expands in the length direction, the mattress insertion / removal operation can be easily and quickly performed. It is possible to reduce the work load at the facility for exchanging sheets, and the working time can be greatly shortened.
(3) Since the lower surface of the mattress is wrapped around the lower surface of the mattress body, even when the mattress is erected on a gadget bed, the sheet main body loosens and becomes wrinkled, or the mattress is exposed by dripping Can be prevented.
(4) The pair of presser cloths that sew one side to the end face cover of the sheet body with the tip end overlapped, do not sew the overlapped part, so that the mattress insertion / removal opening is wide when inserting / removing the mattress. Since it greatly expands in the direction, mattress insertion / removal work can be performed easily and quickly. And the mattress accommodated can be reliably pressed down from the lower surface side.
(5) Since the pair of presser cloths are arranged approximately 12 to 13 cm apart in the longitudinal width direction of the sheet body, the mattress insertion / removal opening is widened in the longitudinal direction when the mattress is inserted / removed so that the insertion / removal work is easy. And it can be carried out quickly and efficiently.
