Description

  The present invention relates to a mattress used in a hospital bed or the like, and a mattress sheet detachably attached to the mattress so as to cover an air mat included in one form of the mattress. For sheets.

  A mattress used in a hospital bed or the like is detachably fitted with a mattress sheet so as to cover the mattress. Such a mattress sheet may be a sheet-like type or a bag-like type. There is a box-shaped type formed.

  Sheet-type mattress sheets are designed to push and hold the front, back, left and right sides of the mattress sheets under the mattress, which is troublesome. In addition, there is a problem that the mattress sheets are likely to be displaced due to the sleeping person's turning over.

  Box-type mattress sheets often have a structure in which an opening for inserting and removing the mattress is formed on one side of a box-shaped woven fabric, and rubber is attached around the opening, and there is rubber around the opening. Therefore, there are a problem that it is difficult to fold, and a problem that rubber is deteriorated by chemicals due to repeated commercial cleaning.

  In view of this, a box-shaped mattress sheet has been proposed that eliminates the deterioration of rubber that accompanies repeated cleaning for business use and the difficulty of folding due to the presence of rubber around the opening. What was described in patent document 1 is known.

  The sheet for mattress described in Patent Document 1 includes a sheet main body portion formed of a woven fabric and a pair of bag-shaped portions formed of a knit material and sewn to both ends in the longitudinal direction of the sheet main body portion. Is formed. When the mattress sheet is attached to the mattress, the opening of the mattress sheet includes an edge of the bag-like portion located on one side of the mattress and an edge of the sheet main body located on the same side of the mattress. It is surrounded by.

  Accordingly, since a part of the peripheral edge of the opening portion of the mattress sheet is formed of a stretchable knit material, the opening portion is widened when the mattress sheet is attached to and detached from the mattress. The mattress sheets can be easily attached and detached by inserting and removing the mattress.

  In addition, since no rubber is used around the opening, it is possible to solve problems such as deterioration of rubber due to repeated commercial cleaning, and difficulty in folding mattress sheets due to the presence of rubber.

  However, the mattress sheet described in Patent Document 1 does not consider the following points.

  When the mattress sheet described in Patent Document 1 is ironed using an ironing machine such as an ironer, a bag-like portion positioned on one end side in the longitudinal direction of the mattress sheet that has been cleaned is inserted into the charging machine. The mattress sheet is put into the ironer by sandwiching it with a clip and sucking the other end side of the mattress sheet with the suction part of the feeding machine. However, when the other end side of the mattress sheet is sucked, the bag-like portion formed of the knit material sandwiched between the clips is extended, and one end of the mattress sheet is inserted before the other end side of the mattress sheet enters the ironer. The side may come off from the clip of the feeder, and ironing with the ironer may fail.

  The present invention has been made to solve such a problem, and its purpose is a sheet for a box-type mattress in which no rubber is provided around the opening, and the sheet is loaded into an ironer using a dosing machine. It is to provide a mattress sheet that can be reliably performed.

  A first feature according to an embodiment of the present invention is a box-shaped mattress sheet that is detachably attached to a rectangular parallelepiped mattress so as to cover the mattress, and is formed of a single woven fabric. And when mounted on the mattress, a surface portion covering the top surface of the mattress, a pair of side surfaces covering the side surfaces along the longitudinal direction of the mattress, and a longitudinal direction of the mattress on the bottom surface of the mattress. A sheet body having a pair of back surfaces covering a part of the side surface, and a stretchable knit material, sewn at both longitudinal ends of the sheet body, and attached to the mattress. A pair of stretchable surface portions covering both ends of the mattress in the longitudinal direction on the lower surface of the mattress, and attached to the mattress In addition, an opening is formed to allow the mattress to be taken in and out at a position surrounded by an edge portion of the stretchable surface portion facing the center direction of the mattress and an edge portion of the back surface portion facing the center direction of the mattress. That is.

  According to the present invention, when the mattress sheet is inserted into the ironer using the charging machine, the stretchable surface portion does not extend, and the mattress sheet can be reliably charged into the ironer using the charging machine. it can.

It is a perspective view which shows the bed sheet for mattresses of one embodiment of this invention from the side in which the opening part is formed. It is an expanded view which shows the state before sewing a sheet | seat main-body part and an expansion-contraction surface part. It is a perspective view which shows the state which mounted the mattress sheets on the mattress from the lower surface side of the mattress. FIG. 4 is a sectional view taken along line AA in FIG. 3. It is a perspective view which shows the state which mounted the mattress sheets on another mattress from which thickness differs from the lower surface side of a mattress.

  Hereinafter, a mattress sheet 1 of a box type according to an embodiment of the present invention will be described with reference to the drawings. The mattress sheet 1 is detachably mounted on a rectangular parallelepiped mattress 2 used in, for example, a hospital bed so as to cover the mattress 2 and is formed of a single woven fabric. The sheet main body 3 is formed by a pair of stretchable surface parts 4 that are formed of a stretchable knit material (knitted material) and sewn to the sheet main body 3. As the woven fabric constituting the sheet body 3, for example, cotton, polyester, a blend of cotton and polyester, or the like is used.

  When the mattress sheet 1 is attached to the mattress 2 as shown in FIGS. 3 and 4, the sheet main body 3 includes a surface portion 3 a that covers the upper surface 2 a of the mattress 2 and a pair of the mattress 2 along the longitudinal direction of the mattress 2. A pair of side surface portions 3b covering the side surface 2b and a pair of back surface portions 3c covering a part of the side surface 2b side along the longitudinal direction of the mattress 2 on the lower surface 2c of the mattress 2 are provided. The surface portion 3a, the side surface portion 3b, and the back surface portion 3c are formed continuously, and the boundary between the surface portion 3a, the side surface portion 3b, and the back surface portion 3c is not clearly distinguished, and the mattress sheet 1 The boundary between the front surface portion 3a, the side surface portion 3b, and the back surface portion 3c is appropriately changed according to the thickness dimension of the mattress 2 to which is attached.

  As shown in FIG. 2, the stretchable surface portion 4 is formed in a substantially trapezoidal shape including a long side portion 4 a, an edge portion 4 b curved in a concave shape, and a pair of inclined side portions 4 c. The stretchable surface portion 4 is sewn to the sheet body portion 3 by sewing the long side portion 4a to the edge portions 3d on both ends in the longitudinal direction of the surface portion 3a, and the inclined side portion 4c to the side surface portion 3b and the back surface portion 3c. Is performed by sewing on the edge 3e formed continuously.

  When the mattress sheet 1 is mounted on the mattress 2, the edge portions 4b of the pair of stretchable surface portions 4 facing the center direction of the mattress 2 and the edge portions 3f of the pair of back surface portions 3c facing the center direction of the mattress 2 An opening 5 for inserting and removing the mattress 2 with respect to the mattress sheet 1 is formed at a position surrounded by.

  At the four corners of the mattress sheet 1, when the mattress sheet 1 is attached to the mattress 2, there are one opening 6 positioned opposite to the end portions of the side surfaces 2 d on both ends in the longitudinal direction of the mattress 2. A total of four are formed. The opening 6 is formed by not sewing a part of the long side portion 4a of the stretchable surface portion 4 when the edge portion 3d of the surface portion 3a of the sheet main body portion 3 is sewn.

  As shown in FIG. 1, a crease 7 is formed in the outer peripheral portion along the longitudinal direction of the mattress sheet 1 in a flat state not attached to the mattress 2, and the long side portion 4a and the surface portion 3a of the stretchable surface portion 4 are formed. A sewing line 8, which is a portion where the edge 3 d is sewn, is formed on the same plane as the crease 7. Therefore, when the mattress sheet 1 is ironed by an ironing machine such as an ironer (not shown) after the mattress sheet 1 is cleaned, the mattress sheet 1 is folded in two along the fold line 7 and the sewing line 8. In this state, the sheet is conveyed by a charging machine (not shown), loaded into an ironer, and ironed.

  In such a configuration, a part of the peripheral edge portion of the opening 5 of the mattress sheet 1 is formed by the stretchable surface portion 4 of a stretchable knit material, so that the mattress sheet 1 is attached to and detached from the mattress 2. In this case, the stretchable surface portion 4 extends and the opening 5 widens, and the mattress sheet 1 can be easily attached to and detached from the mattress 2 by inserting and removing the mattress 2 from the opening 5.

  Moreover, since the edge 4b facing the opening 5 in the stretchable surface portion 4 is curved in a concave shape, when the mattress sheet 1 is attached to the mattress 2, the edge of the mattress 2 is connected to the stretchable surface portion 4 and the surface portion. 3a, and when the mattress sheet 1 is removed from the mattress 2, the edge of the mattress 2 can be easily taken out between the stretchable surface portion 4 and the surface portion 3a. The attachment / detachment work of the sheet 1 can be performed more easily.

  When the mattress sheet 1 is cleaned and then ironed using a loading machine and an ironer, the stretchable surface portion 4 positioned on one end side in the longitudinal direction of the mattress sheet 1 and the surface portion 3a of the sheet body portion 3 Is inserted between the clips of the charging machine, and the other end side of the mattress sheet is sucked and pulled by the suction part of the charging machine, whereby the mattress sheet 1 is inserted into the ironer from the other end side. At this time, since the sheet main body 3 formed of a woven fabric that is difficult to expand and contract is located on one end side of the mattress sheet 1 sandwiched between the clips, the stretchable surface 4 does not extend and the mattress sheet 1 does not extend. The other end can be reliably charged into the ironer, and ironing using the charging machine and the ironer can be reliably performed.

  Next, one opening 6 is formed at each of the four corners of the mattress sheet 1 so as to be opposed to the end portions of the side surfaces 2d on both ends of the mattress 2 in the longitudinal direction. By forming these openings 6, when the mattress sheet 1 is attached to the mattress 2, the opening 6 opens in the thickness direction of the mattress 2, and the corner portion of the mattress sheet 1 jumps outward. Is prevented. As shown in FIG. 5, when the mattress sheet 1 is attached to the mattress 2 having a large thickness, the opening 6 opens further according to the thickness of the mattress 2. Therefore, this one type of mattress sheet 1 can be mounted on various mattresses 2 having different thickness dimensions without causing the corner portion of the mattress sheet 1 to protrude outward.

  Further, since the openings 6 are formed at the four corners of the mattress sheet 1, even when the dust enters the inner corner of the mattress sheet 1, the dust can be easily taken out from the opening 6.

  Further, since the position of the opening 6 is a position facing the ends of the side surfaces 2d on both ends in the longitudinal direction of the mattress 2, the opening 6 is blocked by side plates or the like located on both ends in the longitudinal direction of the bed. Invisible during normal use. Thereby, it can prevent that the opening 6 is visible in the outer peripheral part of the sheet 1 for mattresses, and the opening 6 impairs the external appearance of a bed.

  Further, when a box-type sheet is mounted on an air mat having a floor slip prevention function as the mattress, the mattress sheet 1 can be used. This is because the openings 6 are formed at the four corners of the mattress sheet 1, and any one of these openings 6 can be used to pass a pipe for taking air into and out of the air mat. Therefore, the mattress sheet 1 can be used as a normal mattress 2 or a box-shaped sheet covering the air mat, and the box-shaped sheet mounted on the normal mattress 2 and the box shape mounted on the air mat. There is no need to prepare two separate types of sheets.
