Description

  The present invention relates to a sheet used by covering a lower bedding such as a mattress or a mattress, and is particularly suitable for use in a facility with a lot of daily replacement work such as a hospital, a nursing facility, a medical facility, etc. The present invention relates to a sheet for a lower lower bedding.

  Traditionally, hospitals, nursing homes, and medical facilities have used beds with mattresses on mattresses. Further, in recent years, it has been proposed that the mattress is made to play the role of mattress only by using the mattress material and shape, and the partitioning part of the three-part cassette cover. (For example, Japanese Utility Model Laid-Open No. 59-150352, Japanese Patent Laid-Open No. 11-128028, etc.)

  In hospitals, nursing facilities, medical facilities, etc., there are many sheets to be replaced on mattresses and mattresses, and it is natural that the number of replacement work can be reduced as much as possible so that it can be performed quickly and smoothly. However, it is required that it does not shift during use. As a response to such a request, as shown in FIG. 10, a sheet portion and a folded portion are formed by folding back the longitudinal end of the sheet body 1, and a predetermined length is sewn from both ends of the folded portion, It has been proposed to form an insertion part for inserting a mattress or mattress tip in the middle to shorten the positioning of the mattress or mattress and the folding of the sheets at the time of replacement. In a sheet provided with such an insertion portion, the force applied when inserting the tip of a mattress or the like is concentrated on one point of the end point of sewing, and the sheet is likely to be damaged. When trying to improve workability, the risk of breakage increased.

Japanese Patent Laid-Open No. 2001-286370 discloses an insertion portion in which a cross-shaped sewing portion is provided as shown in FIG. 11 and a leading end portion of a mattress or mattress is inserted instead of sewing from both ends of the folded portion. Has been proposed to form. According to this method, the sewing strength is improved as compared with the above method, but if it is pulled too hard to work, it may be damaged, which is not yet sufficient.
In hospitals, nursing homes, medical facilities, etc., the number of times of washing is increased along with the exchange of sheets, and the ironing after washing is also performed with a high-temperature roll iron of 160 ° C, for example. There is a risk of breakage if there is a point where force concentrates even in deterioration.

In the sheets in which the folded portion is simply folded and overlapped on the sheet main body and sewn from both ends as shown in FIGS. 10 and 11 or the insertion portion is formed by forming the sewn portion, the leading end portion of the mattress, mattress or the like In most cases, the folded portion becomes slack when inserted. When the leading end of the mattress or the like is inserted into the sheet on which the insertion portion is formed as shown in FIG. 10, the folded portion is inserted so that the sewing seam is located in the middle of the thickness direction of the side of the mattress or the like. Although it does not sag, in most cases, the seam stitch is shifted downward, and the surface side of the sheet is in a stretched state, but the folded portion on the back side is in a sag state. Also in the case as shown in FIG. 11, when the tip is inserted, the stitched portion is not exactly in the middle of the thickness direction of the mattress or the like, but is shifted downward and the folded portion that becomes the back surface is slackened. turn into.
In this way, if the folded part on the back side is in a slack state, when doing the folding work on the opposite side in the replacement work, it will come off and it will start again There is a need.
JP 2001-286370 A

It is an object of the present invention to provide a sheet for a lower bedding that can be performed quickly and smoothly by reducing the number of steps as much as possible, and that is difficult to break by dispersing the force applied during work.

The present invention solves the above problems,
1) Folding at least one longitudinal end of the sheet fabric that is longer and wider than the lower bedding that is assumed to be used to the back side with a required width, the sheet fabric is separated from the sheet portion and the folded portion. And forming a pair of sewn bodies by attaching the end portion of the folded portion and the sheet portion to form an insertion portion composed of the sheet portion and the folded portion, and the pair of the sheet fabrics. A sheet having an outer portion as a laid portion from the sewn body, wherein the sewn body has a straight seam formed parallel to the end of the folded portion and a linear straight line in an oblique direction following the seam . The lower bedding sheet 2) is characterized by being formed from a seam and a longitudinal linear seam following the seam, and is cut longer and wider than the lower bedding assumed to be used. At least one ear side of the sheet fabric is required on the back side The sheet fabric is formed into a sheet portion and a folded portion by folding back, and the sheet portion and the folded portion are provided by sewing the end portion of the folded portion and the sheet portion to provide a pair of sewn bodies. The sheet fabric is a sheet having an outer portion extending from the pair of sewn bodies, and the sewn body is formed in parallel with the ears of the folded portion. was lower bedding sheets 3, characterized in that it is formed from a straight seam and the subsequent diagonal linear straight stitch seam in the width direction further subsequent) folding unit Sheets for lower bedding 4) Folding portion, characterized in that the seam formed in parallel with the end of the sheet and the oblique seam following the seam are formed in an oblique 45 ° direction. So that the distance between the sewn bodies of the sheet is shorter than the distance between the sewn bodies of the sheets. Each of the sewn bodies is shifted inwardly by a length corresponding to the thickness of the lower bedding from the half of the thickness of the lower bedding assumed to be used. it is formed by sewing Te, those sheets portion to gist the sheets for the lower bedding, characterized in state near Rukoto slackened as compared to the folded portion.

  The sheet for the lower bedding of the present invention has a required width on the back side at least one end in the longitudinal direction of the sheet fabric that is cut longer and wider than the length of the lower bedding such as a mattress or mattress to be used. The sheet fabric is formed into a sheet portion and a folded portion by folding back, and the sheet portion and the folded portion are formed by attaching the end portion of the folded portion and the sheet portion and providing a pair of sewn bodies. Since it is a sheet that forms the insertion part and the outer part of the sheet fabric is the laying part from the pair of sewn bodies, when replacing the sheet, the leading part of the mattress or mattress is inserted into the insertion part. By inserting and folding the laying portion downward, it is possible to reduce the number of replacement work as much as possible and to perform it quickly and smoothly, and to prevent shifting during use.

  In addition, the sheet for the lower bedding of the present invention, which is longer than the lower bedding assumed to be used, and by folding at least one ear side of the sheet fabric cut into a wide width to the back side with a required width, By defining the sheet fabric into a sheet portion and a folded portion, and sewing the end portion of the folded portion and the sheet portion to provide a pair of sewn bodies, an insertion portion composed of the sheet portion and the folded portion is formed. In the case where the sheet is formed and the sheet is formed as a laid portion from the pair of sewn bodies of the sheet fabric, the number of replacement work can be reduced as quickly as possible, and can be performed quickly and smoothly. It is possible to prevent shifting during use.

In the present invention, the seam provided to form the insertion portion is formed with a seam formed in parallel to the end of the folded portion, the diagonal seam that follows, and the longitudinal seam that follows the seam. Since the force applied to the sewn body of the insertion portion during the replacement work is dispersed without concentrating on one point, the sheet is less likely to be damaged.

In the present invention, when the sewn body is provided so that the interval between the seams of the folded portion is shorter than the interval between the sewn bodies of the sheet portion, the leading end portion of the mattress, mattress, or the like when the sheet is replaced When the card is inserted, the folded part becomes slack and does not come off even though it is inserted at the corner, so that it is possible to perform the replacement work more quickly and smoothly. .

  The sheet for the lower bedding of the present invention is at least one end side in the longitudinal direction of the sheet fabric that is cut longer and wider than the lower bedding such as a mattress or a mattress to be used, or at least one ear side of the sheet fabric. The sheet fabric is formed into a sheet portion and a folded portion by folding it back to the back side with a required width, and an end portion of the folded portion and the sheet portion are sewn to form a mattress or mattress insertion portion. The bed sheet for lower bedding, which can facilitate the replacement work and has a structure in which the force applied during the replacement work is sewn into a stitch shape that does not concentrate on one point and the force is dispersed.

  FIG. 1 shows a sheet 1 in which an insertion portion 5 is formed by folding back both ends in the longitudinal direction of a sheet fabric, which is an embodiment of the present invention, to a back surface with a required width to provide a sewn body 4. FIG. The state which inserted the mattress 7 in the part is shown. FIG. 3 shows a sheet 8 in which the insertion portion 12 is formed by folding the both ears of a sheet fabric, which is another embodiment of the present invention, to the back side with a required width to provide a sewn body 11. 1 to 3 are depicted with the back side up for ease of explanation.

In FIG. 1, the sheet fabric is longer than the length of the mattress or mattress to be used, and is cut to be wider than the width thereof, and the end portion in the longitudinal direction is folded back by the required width to be folded back with the sheet portion 2. An insertion portion 5 is formed which is defined in the portion 3 and is inserted into the end portion of the mattress by sewing the end portion of the folded portion 3 and the sheet portion to provide a pair of sewn bodies 4. The distance between the pair of sewn bodies 4 is sufficient to insert the tip of the mattress.

In the present invention, as shown in FIG. 4, the shape of one sewn body 4 includes a straight seam A formed in parallel with the end of the folded portion and a linear seam in the oblique direction following the straight seam A. It is further formed continuing from the longitudinal direction of the straight seam C to the B. FIG. 4 is an enlarged view of the upper left part of FIG. 1 showing the shape of one sewn body in an easy-to-understand manner. In this way, when one end in the longitudinal direction of the sheet fabric is folded back to the back side with a required width The sewn body has a straight seam A formed parallel to the side of the end of the folded portion and extending from the ear direction toward the middle direction, followed by an oblique direction toward the folded side. It consists of a linear seam B formed and a linear seam C formed in the longitudinal direction toward the return side.
In this case, the stitch A may be a stitch formed continuously from the ear portion, but a stitch number of about several is sufficient to achieve the object of the present invention. It is also preferable from the viewpoint of workability to provide a sewn body as shown in FIG. The seam B is formed in an oblique direction toward the turn-up side, and this inclination α may be 30 ° to 60 °, and is preferably about 45 ° because the force is distributed in a balanced manner. The number of stitches is about 2 to 15 and preferably 5 to 10. The first length is preferably 1 to 3 mm.

  As shown in FIG. 3, when both ears of the sheet fabric are folded back to the back side with a required width, the sewn body 11 is parallel to the ears of the folded portion 10 and is directed in the middle direction from the folded end portion. The seam A is formed, the seam B is formed in an oblique direction toward the folding side, and the seam C is formed in the width direction of the sheet fabric toward the folding side. ing.

FIG. 5 schematically shows the relationship between the warp and the weft when the woven fabric is used as the sheet fabric in the case where the sewn body is formed as in the present invention (a) and the case where it is formed in the conventional cross shape (b). Show. When it is formed in a cross shape as in the prior art (b), when a force is applied to the seam, it is easily damaged by any one of the warp and weft threads. If the sewn body is formed of a seam formed in parallel with the end of the folded portion, an oblique seam that follows this, and a longitudinal seam that follows this seam, It can be easily guessed that the force is distributed to the plurality of yarns when applied.

  When the sheet of FIG. 1 according to the present invention is put to practical use, a tip end portion such as a mattress is inserted into the insertion portion, and the outer portion is folded from the sewing body as a laying portion and used. In the case of FIG. 3, both sides, such as a mattress, are inserted in an insertion part, and the outer part is used as a laying part from a sewing body, and it folds in the back side, and is used.

In the present invention, as shown in FIG. 1, a sewn body 6 may also be provided at the ear of the folded portion to stop the corner of the folded portion. Further, the end portion of the folded portion may be sewn from the ear portion to the vicinity of the sewing body 4. Further, FIG. 1 shows a case where both the upper and lower end portions of the mattress are inserted, but the insertion portion may be formed only on one side, for example, only the head side or the foot side. Aim can be achieved. In this way, when the insertion portion is formed only on one side, the other side may be left in the fabric state and used for folding, but a sewing body is provided as shown in FIG. Alternatively, the snap 13 may be attached. When the snap 13 is attached, if a plurality of snap buttons 14 that engage with the snap buttons of the folded portion are attached to the sheet portion side, it becomes possible to deal with mattresses and mattresses having different lengths.

  Even when the sewn body is provided by folding the ear side of the sheet fabric back to the back side with a required width, the sewn body 11 may be provided only on one ear side, and the other side may be used only by folding. Moreover, it replaces with providing a sewing body as shown in FIG. 7, and you may attach the snap 13. FIG. When the snap 13 is attached, if a plurality of snap buttons 14 that engage with the snap buttons of the folded portion are attached to the sheet portion side, it becomes possible to deal with mattresses and mattresses having different widths.

  As another preferred embodiment of the present invention, as shown in FIG. 8, the sewn body 4 is provided so that the interval between the sewn bodies 4 in the folded portion 3 is shorter than the interval between the sewn bodies in the sheet portion 2. There is a case. In FIG. 8, each sewn body 4 is formed by sewing by shifting the ears of the sheet portion inward by a length L corresponding to the thickness of the mattress from a length that is half the thickness of the mattress assumed to be used. Thus, the length between the sewn bodies is in a state in which the sheet portion is slacker than the folded portion. In this way, in the sheet replacement work, for example, when the head-side mounting work is finished and the work on the opposite side is being done, the work-side head side of the bent corner has come off and must be redone. There will be no state.

Even when the sewn body is provided by folding the ear side of the sheet fabric back to the back side with a required width, as shown in FIG. 9, the interval between the sewn portions of the folded portion 10 is the interval between the sewn bodies of the sheet portion 9. The sewn body 11 can be provided to be shorter. In this case, each sewn body is formed by sewing with both ends of the sheet portion shifted inward by a length L corresponding to the thickness of the mattress from a half of the thickness of the mattress assumed to be used. Thus, the length between the sewn bodies is in a state in which the sheet portion 2 is slacker than the folded portion 3. In this way, in the sheet replacement work, for example, when the installation work on one side is finished and the work on the opposite side is being done, the folded work head side has come off and the work has to be started again. It does not become such a state. FIG. 9 shows a case where the sewn body 11 is provided only on one ear side, and the snap 15 is attached to the other ear side. The snap button 16 that engages with the snap button of the folded portion is shown in the sheet portion. If a plurality are attached to the side, mattresses and mattresses with different widths can be accommodated.

As the sheet fabric in the present invention, either a woven fabric or a knitted fabric can be used, but the effect of the present invention is more exerted when using a woven fabric that tends to tear when the force is concentrated on one point.

  The sheet for the lower bedding of the present invention can be used for general households and can also be used for home care, but is particularly suitable for facilities with a lot of daily replacement work such as hospitals, care facilities, medical facilities, etc. It can be used.
