Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a waterproof sheet structure used for infants, sick people, bedridden elderly people, etc., more specifically, it prevents sheets from slipping and prevents sleeping urine from entering the mattress and is easily removable from the mattress. The present invention relates to a waterproof sheet structure having various structures.

[0002]

[Prior art]

 Infants, sick people, and bedridden elderly people who find it difficult to stool by themselves are generally put to sleep with a disposable diaper.

However, a paper diaper cannot completely prevent urine and urine from leaking to the outside, and often leaks from the side and stains the mattress.

[0004] Therefore, conventionally, a waterproof sheet having a size of 50 to 70 cm square is laid on the backside of the sheets laid on the futon or a position corresponding to the butt on the front side so as to prevent invasion of urine and duvet into the futon. I have to.

[0005]

[Problems to be solved by the device]

 However, the conventional waterproof sheet is laid only on the sheets or under the sheets at the position corresponding to the butt, so the range of defense is narrow, and if the butt shifts due to rolling over, the waterproof sheet will be damaged. In many cases, it leaks to the outside, and the reality is that the waterproof effect cannot be exerted due to slipping or slipping together with the sheets.

Even if a waterproof sheet having the same size (area) as the mattress is laid, it is inevitable that the waterproof sheet will be displaced due to the “deviation” and “closeness” of the sheets.

It is also difficult to frequently reposition the waterproof sheet.

[0008] On the other hand, the work of replacing the sheets has conventionally been a method in which a rectangular flat cloth sheet, which is about 50 cm in length and width, is larger than the size of the mattress and folds the top, bottom, left and right edges to the bottom of the mattress, which is troublesome. Therefore, it was unavoidable that the sheets gradually slipped off the mattress and slipped due to turning over.

[0009] In this respect, bag-like sheets having a structure in which the bedding wraps around the backside of the bedding and the edges of the sheets are squeezed with rubber are commercially available.

However, since the bag-like sheets have a bag-like shape, they are difficult to dry, have a problem in that they dry slowly in washing and are difficult to fold.

The present invention has been made in view of the above circumstances, has a structure that does not displace from the mattress, is easy to replace and wash, and has a waterproof effect that can completely prevent leakage to the mattress. A waterproof sheet structure is provided.

[0012]

[Means for Solving the Problems]

 The present invention is as follows: (1) According to the size of the mattress, the right and left edges of a rectangular flat cloth sheet having air permeability and water permeability are folded downward with a width of 10 to 30 cm, and the upper and lower edges are respectively 20 to 40 cm. The width of the sheets is folded downward, and the overlapping parts of the folded corners are sewn together. The backside of the sheet body is designed to wrap around the comforter and has a length of 120 to 200 cm and a width of 80 to 100 cm. By providing a waterproof sheet structure characterized in that a waterproof sheet made of synthetic resin is sewn and fixed, (2) In the waterproof sheet structure according to (1) above, the waterproof sheet is a sheet body. A waterproof sheet, in which clasps are provided at 4 to 20 points including four corners around the waterproof sheet and corresponding points of the sheet body so as to be detachable from the sheet. The above object is achieved by providing a structure.

The above-mentioned rectangular flat cloth sheet having air permeability and water permeability is a sheet made of a normal cotton cloth or other synthetic fiber material, and a single sheet has a width of about 250 cm and a width of 140 cm.

Further, the waterproof sheet means a sheet mainly composed of polyurethane or other waterproof synthetic resin, or a synthetic fiber cloth having waterproofness or water repellency. It means a waterproof sheet with a cotton fabric attached.

[0015]

[Embodiment of the invention]

 An embodiment of a waterproof sheet structure according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan view seen from the back side for explaining a waterproof sheet structure according to claim 1 of the present invention.

FIG. 2 is a partially enlarged view showing a corner of a waterproof sheet having a waterproof sheet structure according to claim 2 of the present invention.

First, referring to FIG. 1, in the waterproof sheet structure of the present invention, the dimensions as shown by the broken lines are approximately Y = 250 cm in length and X = 140 cm in width, and have a rectangular shape in plan view with air permeability and water permeability. The left and right edges 1a, 1b of the flat cloth sheet 1 are folded downward with a width of X1 = 10 to 30 cm (front side in FIG. 1), and then the upper and lower edges 1c and 1d are respectively Y1 = 20 to 40 cm wide. Fold it downwards and sew the overlapping parts 2A, 2B, 2C, 2D of the folded corners along the dotted line 3 to wrap it around the mattress (not shown) (in other words, hold it. The sheet having the covering structure is the sheet body 7 of the waterproof sheet.

A quadrilateral window 9 having a length of about 150 cm and a width of about 90 cm is opened on the back side of the sheet body 7, and a pocket 11 into which the four corners of the mattress is properly inserted is provided at the top, bottom, left and right. , 12, 13, and 14 have a bag-like structure.

The depth of each of the upper and lower pockets 11 and 12 is about 25 cm, and the depth of each of the left and right pockets is about 15 cm. The corners e, f, g, and h of these pockets are consistent with the corners of the mattress. The coincidence corrects the deviation of the sheets.

To attach and detach the mattress to the main body of the waterproof sheets, roll the mattress using the window 9 so that the four corners come to the corners e, f, g and h of the upper and lower pockets 11 and 12, respectively. It will be clear that insertion can be done easily and quickly.

Next, on the back side of the sheet body 7 (that is, between the upper surface of the mattress and the sheet body that covers the sheet), a waterproof sheet made of synthetic resin having a length of 120 to 200 cm and a width of 80 to 100 cm. 8 is sewn around and fixed to the back of the sheet body.

In a single-size futon, the length and width of the mattress is approximately 200 (cm) × 100 (cm), so that the waterproof sheet 8 according to the present invention is considerably larger than the conventional one, and the entire area of the mattress is almost the same. Will cover it.

The waterproof sheet structure of claim 1 is a structure in which the waterproof sheet 8 is directly sewn around the back surface side of the sheet body 7, and the portion has a double structure for washing. The disadvantage is that it dries slightly slower than standard sheets.

In addition, the inconvenience that the waterproof sheet 8 and the sheet body 7 cannot be replaced remains.

Therefore, in the waterproof sheet structure according to claim 2 of the present invention, as shown in FIG. 2, the waterproof sheet 8 is not directly sewn to the seat body 7 but is detachable so that the waterproof sheet 8 is removable. 8 to 4 around the four corners 8a, 8b, 8c, 8d and the corresponding portions of the sheet body 7 are provided with retainers 15 (typically so-called snap buttons).

Therefore, since the waterproof sheet 8 can be detached from the sheet body 7 by the clasp 15, it is possible to easily remove the waterproof sheet and wash them separately when washing.

In addition, the conventional waterproof sheet is often used by laying it on the upper surface of the sheet, but this has a drawback that it is uncomfortable to touch due to its waterproof property and it easily gets damp. Since it is located on the back side of the main body, the above difficulties have been solved.

Originally, in hospitals and the like, the sheets are supposed to be replaced almost every day for hygiene, so it is sufficient that the mattress itself is not dirty, and the sheets may be dirty. The problem is that the sheets leak out of the sheet and the waterproof sheet to penetrate the sheets and stain the bedding, and the sheet replacement work is complicated.

The retainer 15 is provided only around the waterproof sheet 8 so that the sleeping person does not touch the sleeping person and does not disturb the sleeping person. In this respect, it is desirable that the size of the waterproof sheet 8 covers the upper surface almost completely in accordance with the size of the mattress.

Further, the number of the clasps 15 is set to 4 to 20 points, but this is the minimum number for fixing the four corners as the lower limit, and the result of considering the convenience of attachment and detachment while fully preventing the deviation. It is the upper limit.

The material of the waterproof sheet 8 is a synthetic resin such as polyurethane, and a synthetic resin sheet may be used alone. However, a sheet with a cotton cloth attached to one side thereof is already on the market, so this sheet should be used. Would be simple.

In addition, as a precaution, the waterproof sheet 8 in the present invention is attached to the sheet body by sewn fixation or a clasp such as a snap button, and no magic tape is used. Velcro tapes, which are commonly used as removable means, are easily broken by washing and lint easily adhere to them, so sheets that require high washing frequency cannot withstand long-term use.

As described above, the waterproof sheet structure according to the present invention is a very useful idea which is excellent in handling of washing and replacement while fully utilizing the effect of the waterproof sheet, despite the simple structure.

[0035]

[Effect of the invention]

 Since the waterproof sheet structure according to the present invention is configured as described above, (1) the sheets can be easily replaced, and the sheets themselves have an excellent effect that they are not displaced with respect to the bedding.

(2) It has an excellent effect that the waterproof sheet is not displaced with respect to the sheet body and a sufficient waterproof effect is always obtained.

(3) Since it is a detachable type waterproof sheet, it has an excellent effect that the laundry dries quickly and only the waterproof sheet or the sheet body can be replaced.
