Description

  The present invention relates to a mattress sheet that is detachably attached to a mattress used in a hospital bed or the like.

  For mattresses used in hospital beds, etc., regarding mattresses used in hospital beds, etc., and mattress sheets that are detachably attached to the mattress so as to cover an air mat included in one form of the mattress The mattress sheets are detachably mounted so as to cover the mattress, and the mattress sheets include a sheet type and a box type formed in a bag shape. .

  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. For this reason, there are a problem that it is difficult to fold and a problem that the rubber is deteriorated by the cleaning solvent as the cleaning for business use is repeated.

In view of this, there has been proposed a box-shaped mattress sheet 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. Those described in Document 1 are known.

  In the mattress sheet described in Patent Document 1, since a part of the peripheral edge of the opening is formed of a stretchable knit material, the opening is used when the mattress sheet is attached to and detached from the mattress. Therefore, the mattress sheets can be easily attached and detached by taking the mattress in and out of the opening. 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, in the mattress sheet described in Patent Document 1, there is room to consider the following points.

  In other words, when ironing a mattress sheet using an ironing machine such as an ironer, or folding the mattress sheet using an automatic folding machine, the mattress is sandwiched between a bag-like portion located at one end in the longitudinal direction of the mattress sheet. The other end of the sheet is inserted into an ironer or automatic folding machine. However, when loading from the other end of the mattress sheet, the bag-shaped part formed of the knit material sandwiched between the clips stretches or the knit material slips easily. It is assumed that

  The present invention has been made to solve such problems, and its purpose is a box-type mattress sheet that does not have rubber around the opening, and is inserted into an ironer or an automatic folding machine. It is to provide a mattress sheet that can be reliably performed.

  In recent years, mats for preventing wrinkles (preventing floor slippage) have been used on top of ordinary mattresses. Therefore, in addition to variations in the size and thickness of the mattress itself, the thickness of the mat for wrinkle protection Therefore, it has been required to cope with an increase and variation in the overall size and thickness including such variations.

  In order to solve the above problems, a mattress sheet according to claim 1 is a mattress sheet that is mounted so as to detachably cover at least the entire upper surface of a rectangular parallelepiped mattress, and is substantially the entire upper surface of the mattress. And a sheet main body that covers both side surfaces along the longitudinal direction, and at the time of mounting on the mattress, at least eight corners on the upper and lower corners of the mattress and stretchable portions that cover the lower surfaces of both ends in the longitudinal direction of the mattress, When the mattress is attached, the gist is that an opening for inserting and removing the mattress is formed on the lower surface side, and when the mattress is not attached, at least the upper surface side of the longitudinal end is formed by the sheet body.

  The gist of the mattress sheet according to claim 2 is characterized in that, when the mattress is mounted on the mattress, openings are formed at four corners located opposite to the end portions of the side surfaces on both ends in the longitudinal direction of the mattress. .

According to the present invention, the back side of the stretchable part such as a knit is a sheet main body part that is less stretched and slipped, so that the mattress sheet does not stretch or slip off from the clip, and the mattress sheet is automatically folded. Provided is a mattress sheet that can be reliably loaded into a machine and the like, and that can cope with an increase and variation in the overall size and thickness including the mattress and the anti-wrinkle mat.

It is an expanded view which shows the state before sewing the sheet | seat main-body part and expansion-contraction surface part in other embodiment. It is an expanded view which shows the state before sewing the sheet | seat main-body part and expansion-contraction surface part in other embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a mattress sheet according to an embodiment of the present invention from a side where an opening on the lower surface side is formed, and FIG. 2 is a state before sewing a sheet main body portion and an elastic surface portion. FIG. 3 is a perspective view showing a state in which the mattress sheet is mounted on the mattress from the lower surface side of the mattress, and FIG. 4 is a plan view (a), a bottom view (b), and a front view of the mattress sheet. FIGS. 5 (c) and 6 (c) are side views (c) and FIG. 5 (c), respectively. FIG. 5 (a) and FIG.

  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 attached to a rectangular parallelepiped mattress 7 (see FIG. 3) used in a hospital bed so as to cover the mattress 7, for example, one woven fabric. The sheet main body 3 is formed of a fabric, and a pair of stretchable parts 5 are formed of an extensible knit material (knitted fabric), stitched to the sheet main body 3, and sewn together. As the woven fabric constituting the sheet body 3, for example, cotton, polyester, a blend of cotton and polyester, or the like is used.

  2 to 4, the sheet main body 3 includes a longitudinal edge 3 a and a longitudinal edge 3 e which are both ends in the longitudinal direction of the sheet body 3, and both ends in the width direction perpendicular to the longitudinal edges. The inner edge 3m, the oblique edges 3h and 3b that obliquely connect the long edge 3a and the inner edge 3m, and the oblique edges 3d and 3f that obliquely connect the inner edge 3m and the longitudinal edge 3e. It is formed in an octagonal shape in which four corners of a rectangle are cut out.

  The stretchable part 5 (5A, 5B) is surrounded by four sides having the upper base as the inner edge part 5a, the lower base as the outer edge part 5c, and the oblique side part 5b and the oblique side part 5d as legs. The inner edge 5a) is formed in the shape of an isosceles trapezoid that is concavely curved.

  In FIG. 2, the crease 3s, the crease 3t, the crease 5s, and the crease 5t indicated by the two-dot chain line indicate folds that are folded when being sewn. The assumed folding line 3u indicates the position of the edge (inner edge 3m) of the sheet main body 3 that is folded at the fold 3s and the fold 3t.

  In general, the knit material (knitted fabric) of the stretchable part 5 generally has a difference in elongation rate between the vertical direction and the horizontal direction. In this embodiment, the knit material (knitted fabric) has elongation (the amount of elongation is large). By aligning the direction with the width direction and using the direction with less elongation in the longitudinal direction, the mattress 7 can be easily attached to the mattress 7 and more securely held by the clip during washing. Yes.

  As shown in FIG. 3, when the mattress sheet 1 is mounted on the mattress 7, the sheet main body 3 has a front surface covering the upper surface of the mattress 7 (the back surface is not shown in FIG. 3), and the mattress 7. The main body portion of the mattress 7 is covered with a pair of side surface portions covering the pair of side surfaces along the longitudinal direction of the mattress 7 and a pair of back surface portions covering a part of the side surface side along the longitudinal direction of the mattress 7 on the lower surface of the mattress 7. I have to.

  On the other hand, the stretchable part 5 covers the four corners of the mattress 7 body and covers only the back half of the end face of the mattress 7 in the longitudinal direction.

  That is, since the expansion / contraction part 5 is switched to the sheet body part 3 at the outer edge part 5c, at the time of clamping with the clip at the time of washing, the one side of the clamping surface of the clip always holds the woven fabric of the sheet body part 3 Therefore, it is possible to more reliably hold the clip with the clip at the time of washing.

  Note that the front surface portion, the side surface portion, and the back surface portion of the sheet main body 3 are continuously formed, and the boundary between the front surface portion, the side surface portion, and the back surface portion is not clearly distinguished, and the mattress sheet 1 is attached. It goes without saying that the boundary between the front surface portion, the side surface portion, and the back surface portion changes appropriately according to the thickness dimension of the mattress 7.

  In FIG. 4, the codes L1 to L3 are given, but these codes indicate that the lengths of the parts having the same codes L1 to L3 are substantially the same, for example, L1 and It does not indicate the magnitude relationship with L3. These magnitude relationships may change when the mattress 7 and the anti-wrinkle mat are included.

  In addition, at the four corners of the mattress sheet 1, openings (not shown) may be formed one by one so as to face the end portions of the side surfaces on both ends in the longitudinal direction of the mattress 7. Due to the formation of these openings, when the mattress sheet 1 is attached to the mattress 7, the opening opens in the thickness direction of the mattress 7, and the corner portion 5r of the mattress sheet 1 is prevented from jumping outward. In addition, it is further facilitated to be mounted on various mattresses 7 having different thicknesses and external dimensions by laying an anti-wrinkle mat.

In addition, since the openings 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.

  FIG. 5 is a development view showing a state before the sheet main body portion and the stretchable surface portion are sewn in another embodiment, and the edges of the inner edge 5a and the like are straightened to facilitate sewing. is there. FIG. 6 is a development view showing a state before the sheet main body portion and the stretchable surface portion are sewn in another embodiment. The slant side portion 5b and the slant side portion 5d are curved to further enhance the extensibility and the design. It is also improved.

  Further, in the present embodiment, the total length of the stretchable portions 5 stitched to both ends of the sheet main body 3 is aligned with the length of the mattress 7, so that the length of the sheet main body 3 itself can be short. Therefore, so-called widening is possible, and material costs can be reduced.

  In the above description, the color of the fabric is not particularly mentioned. However, in this embodiment, for example, the knit fabric can be any color. Specifically, the size and use of the mattress sheet, the four corners, and the like. It goes without saying that the color may be changed for each customer, or for each customer.

  That is, these mattress sheets are not limited to thickness and size, and can be appropriately changed according to various other conditions.
