  The bedding cover as described above is formed in a size having a margin with respect to the bedding in order to ensure ease of attachment to and removal from the bedding. Therefore, sagging and wrinkles occur in the bedding cover when it is attached to the bedding. Further, in the conventional bedding cover, since the opening is sewn in a gather shape through a rubber band, the sewing wrinkles are conspicuous around the opening. Such slack and wrinkles of the bedding cover at the time of wearing have a problem that the feeling of use is poor and the aesthetic appearance of the wearing state is impaired. Also, there is a problem that the heel part is likely to be leaked when it is removed from the bedding and washed, and it is difficult to handle when it is dried and dried after washing, and it is also difficult to handle when folded and stored after drying. There is also.

  This invention is made | formed in view of such a subject, and it aims at providing the bedding cover with favorable fitting property with few slack and wrinkles at the time of mounting | wearing to bedding.

To achieve the above object, the present onset Ming, a bedding cover made using the cover fabric is stretchable, the cover fabric, and the base of the rectangular shape, a rectangular shape respectively connected to the four sides of the base Four thickness-corresponding portions, and four trapezoidal opening forming portions that are respectively connected to outer sides on the opposite side of the inner side that are connected to the base portion of the four thickness-corresponding portions and have a width that decreases toward the outside. to have a developed shape. Then, the four thickness-corresponding portions are bent inward at right angles to the base portion, and the four opening forming portions are bent inward, and the side edges of the thickness corresponding portion and the oblique sides of the opening forming portion that are in contact with each other are joined. The angle θ with respect to the outer side of the oblique side of the opening forming portion is 45 degrees <θ <90 according to the thickness of the bedding inserted through the opening. It is set within a range of degrees, and in the state where the bedding is inserted, the opening forming portion has a bulge in the height direction from the outer side of the thickness corresponding portion .

  In the bedding cover having the above-described configuration, it is preferable that a hem member made of a fabric having higher elasticity than the cover fabric is sewn to the peripheral edge of the opening with elastic yarn.

  In the bedding cover configured as described above, it is preferable that each of the four opening forming portions has a rounding forming portion that forms roundness at four corners of the opening.

  The bedding cover according to the present invention is formed into a three-dimensional shape having an opening for inserting bedding with a stretchable cover fabric, and has a configuration in which a bulge according to the thickness of the bedding is provided at a portion where the opening is formed. Yes. According to such a configuration, the cover fabric itself has elasticity, and since it has a shape with a bulge according to the thickness of the bedding, there is little sagging and wrinkles when attached to the bedding, Fits comfortably with bedding.

  In addition, if the hem member made of a fabric having a higher elasticity than the cover fabric is sewn to the peripheral edge of the opening with a stretchable thread, the conventional sewed in a gather shape through a rubber band in the opening. There are no sewing wrinkles around the opening unlike the bedding cover. In addition, when removed from the bedding, the bedding cover is not shrunk by the rubber band unlike conventional bedding covers, so when you wash and hang it, you can open the bedding cover and dry it, and it is easy to dry is there.

  Further, if the four opening forming portions have a round forming portion that forms roundness at the four corners of the opening, the opening into which the bedding is inserted can be formed into a rounded shape. The member can be sewn neatly to the periphery of the opening.

It is an expanded view of the bedding cover which concerns on this invention. It is a figure which shows the state before attaching the hem member of the bedding cover which concerns on this invention, (a) is a top view, (b) is a side view. It is a top view which shows the state which attached the hem member of the bedding cover which concerns on this invention. It is a figure when the bedding cover which concerns on this invention is mounted | worn with bedding, (a) is a side view when mounting | wearing with a thin bedding, (b) is a side view when mounting | wearing with a thick bedding.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The bedding cover 1 according to this embodiment is made using a stretchable cover fabric 2 and covers bedding such as pillows, mattresses, and bed mattresses. Examples of the cover fabric 2 include a knitted fabric having a stretchable structure such as a weft knitted fabric (for example, a knit fabric, a jersey fabric) or a warp knitted fabric (for example, a tricot fabric) such as cotton yarn or polyester yarn, Alternatively, a woven fabric using stretchable yarn is used.

  As shown in FIG. 1, the cover fabric 2 includes a rectangular base portion 11, four rectangular thickness corresponding portions 12 connected to the four sides of the base portion 11, and an inner side connected to the base portions 11 of the four thickness corresponding portions 12. It has a developed shape provided with four trapezoidal opening forming portions 13 that are respectively connected to the outer side 12b on the opposite side of 12a and narrow in width toward the outside.

  In the cover fabric 2 having such an unfolded shape, the four thickness corresponding portions 12 are bent inward at a substantially right angle with respect to the base portion 11, and the four opening forming portions 13 are bent inward to form the thickness corresponding portions 12 in contact with each other. By joining the side 12c and the oblique side 13a of the opening forming portion 13 (for example, sewing them together with a thread), a three-dimensional shape having an opening 15 into which the bedding is inserted is formed as shown in FIG. In addition, in FIG. 2, although the square solid shape is shown, since it is actually formed by joining dough materials, it has a rounded solid shape.

The angle θ of the oblique side 13a of the opening forming portion 13 with respect to the outer side 12b is set according to the thickness of the bedding inserted from the opening 15. More specifically, the total angle 2θ obtained by adding the angles θ of the oblique sides 13a joined to each other is set to be larger than 90 degrees by the angle α depending on the thickness of the bedding. Further, the total angle 2θ is set to be smaller than 180 degrees. That is, the total angle 2θ is set in a range of 90 degrees <2θ <180 degrees. In the developed shape of FIG. 1, the angles θ of the hypotenuses 13a joined to each other are set to be larger than the 45 ° by the same angle α / 2. However, for example, one angle θ may be set to be larger than 50 degrees by an angle α / 2, and the other angle θ may be set to be larger than 40 degrees by an angle α / 2. Alternatively, one angle θ may be set to be larger than 45 degrees by an angle α, and the other angle θ may be set to 45 degrees.

Since the angle θ of the oblique side 13a of the opening forming portion 13 is set according to the thickness of the bedding as described above, when the respective sides are joined and formed into a three-dimensional shape as shown in FIG. As described above, the bedding cover 1 is increased in height (bulge) by the height H ₂ by the opening forming portion 13 in addition to the height H ₁ by the thickness corresponding portion 12.

  Each of the four opening forming portions 13 includes round forming portions 14 and 14 that form roundness at four corners of the opening 15. When these rounding portions 14 join the respective sides as described above to form a three-dimensional shape, as shown in FIG. 2A, the four corners of the opening 15 each have a curved shape. Formed.

  As shown in FIG. 3, the bedding cover 1 sews a hem member 20 made of a fabric that is more stretchable than the cover fabric 2 with a stretchable thread (for example, a spandex thread) around the periphery of the opening 15. Configured. The hem member 20 is formed to have a size substantially the same as the size (length) of the peripheral edge of the opening 15 in the free state of the bedding cover 1. Therefore, even if the elastic hem member 20 is attached, the size of the opening 15 is not changed. As a result, the rubber is not attached to the opening portion as in the prior art, and the opening portion is not squeezed in the free state, thereby causing wrinkles. As the fabric constituting the hem member 20, for example, a knitted fabric having a stretchable structure with a thread such as polyester is used.

  As a method of sewing the hem member 20 to the opening 15, for example, a double ring stitch (one needle thread and one looper thread) by flat stitching (a seam with decorative threads on both the front and back sides) is formed. It is preferable to sew by seam (chain stitch) by winding stitches (edge stitching with one thread) According to such a sewing method, the stretchability of the hem member 20 and the cover fabric 2 is not impaired. The part 15 can be greatly expanded.

In the bedding cover 1 configured as described above, the cover fabric 2 having stretchability is formed into a three-dimensional shape having an opening 15 for inserting bedding, and the angle θ of the hypotenuse 13a of the opening forming portion 13 is the thickness of the bedding. By setting it accordingly, the opening forming portion 13 has a configuration with a bulge according to the thickness of the bedding. According to such a configuration, the cover fabric 2 itself has elasticity and has a shape with a bulge according to the thickness of the bedding, so there is less sagging and wrinkles when being attached to the bedding. Can be attached to bedding. Further, the height H ₂ by the opening forming portion 13 shown in FIG. 2B can reduce the tension of the thickness corresponding portion 12 and the opening forming portion 13 when the bedding is actually wrapped and worn, thereby forming the opening. By simply tightening softly with the portion 13 and the hem member 20, it is possible to fit comfortably to the bedding. In addition, in the conventional bedding cover sewn in a gather shape through a rubber band in the opening, the vicinity of the gather portion is loosened, but the other portions are stretched. Furthermore, since the bedding cover 1 has a shape corresponding to the thickness of the bedding, it is possible to reduce the burden (stretching and slackness) of the cover fabric 2 and the hem member 20.

In addition, since the opening forming portion 13 is configured to have a bulge according to the thickness of the bedding, the bedding with various thicknesses can be attached with less tension and slack. For example, as shown in FIG. 4A, when the bedding thickness Z ₁ is smaller than the height H ₁ by the thickness corresponding portion 12, the width of the bedding cover 1 is made slightly smaller than the bedding. Therefore, the bedding cover 1 as a whole is stretched and the slack of the side 12c of the thickness corresponding portion 12 is absorbed in the width direction, so that the bedding can be attached with less tension and slack. Further, as shown in FIG. 4B, when the bedding thickness Z ₂ is larger than the height H ₁ by the thickness corresponding portion 12, the entire bedding cover 1 extends and the hypotenuse 13 a of the opening forming portion 13. As a result, the thickness Z ₂ of the bedding can be supplemented, and the bedding can be attached with less tension and slack.

  Further, the hem member 20 made of a fabric having higher elasticity than the cover fabric 2 is sewn to the peripheral edge portion of the opening 15 with elastic yarn. Therefore, there is no sewing wrinkle around the opening unlike a conventional bedding cover sewn in a gather shape through a rubber band at the opening. Also, when removed from the bedding, the rubber band does not shrink the bedding cover as in the conventional bedding cover, so washing does not occur during washing and the bedding cover can be opened and dried when drying after washing. Easy to fold and store even after drying. Further, by providing the hem member 20, it is possible to prevent the peripheral edge of the opening 15 from fraying and to improve the durability of the bedding cover.

  Further, each of the four opening forming portions 13 has a round forming portion 14. Therefore, each of the four corners of the opening 15 can be formed into a rounded shape having a curve, and the hem member 20 can be sewn cleanly to the peripheral edge of the opening 15.
