Description

The present invention relates to sheets laid in a part of an area such as a bed or a futon.

Conventionally, such sheets are described in, for example, Patent Document 1 (see paragraphs [0011] and [0015]) below.

The sheets are waterproof sheets that are wound around the lower bedding (hereinafter, simply referred to as "bedding") from the back surface of one side portion through the front surface to the back surface of the other side portion. The sheets are wound around the human body lying on the bedding only in a part of the position, for example, around the waist.

In this sheet, a bent portion is formed by bending both ends of the front side and the back side along the winding direction in a double or triple direction or more. This bent portion extends along the longitudinal direction of the bedding and has a thick shape so as to protrude from the main body of the sheet. By laying this bent portion under the bedding, the bent portion is pressed by the weight of the bedding, and the effect of preventing the sheets from slipping is exhibited.

Utility Model Registration No. 3186629

In the sheets of Patent Document 1, since it is necessary to lay the bent portions formed at both ends of the sheets on both sides of the bedding, the operator performs the laying work while moving to both sides of the bedding. There is a problem that it has to be done and the work takes time.

In addition, when the worker cannot enter the back side of the bed, such as when the bedding is placed in contact with the wall or when an object is placed on the back side of the bed, the worker Sheets must be laid from the front side of the bed. In this case, the worker is forced into an unreasonable working posture, and the work of laying the sheets becomes more troublesome, which requires time and labor. Even if the bed is moved, the moving work with the user on it is very complicated, and it is not realistic for the user to feel uncomfortable.

In addition, the sheet laying work also requires creating a wrinkle-free state of the sheets rather than simply covering the bed. This is because the beautifully laid sheets provide a feeling of cleanliness, and especially for the user, the pressure ulcer prevention effect can be obtained. Therefore, it is necessary to securely fix both ends of the sheets to the front side and the back side of the bed.

It is conceivable that the bent portion of Patent Document 1 has a certain degree of rigidity as compared with the main body portion of the sheets and can be easily inserted into the lower side of the bed. However, the rigidity of the sheets is relatively weak, such as being able to be washed in a washing machine. Therefore, in order to beautifully lay the bent portion under the bedding, it is necessary to surely push each of several places along the longitudinal direction of the bent portion under the sheets, which also complicates the work.

In medical and long-term care settings such as hospitals, long-term care facilities, and homes, the number of workers involved in medical care and long-term care tends to be small, and all workers are healthy and have sufficient physical strength. Is not always. When a small number of workers change a large number of bed sheets in a limited time, the workers may be forced into an unreasonable posture, which is not only physically demanding but also causes diseases such as back pain. There is also a concern that it will lead to deterioration.
As described above, there are various points to be improved in the conventional sheets, and conventionally, there has been a demand for sheets that can be laid beautifully with less work load and less time for bedding.

(Characteristic composition)
The characteristic composition of the sheets according to the present invention is
It has a sheet body that is laid in a direction that intersects the longitudinal direction of the bedding with respect to a part of the bedding.
A non-slip material made of a cloth material having a higher frictional force than the sheet body on the surface of the sheet body, which is at least one of the edges along the longitudinal direction and faces the bedding. The point is that it has a part.

(effect)
By providing a non-slip part made of cloth material on the edge of the bedding body like the sheets of this configuration, the non-slip part can be easily caught on the surface of the bedding when the sheets are laid on the bedding. .. For example, when laying sheets from one side of the bedding, a non-slip portion is arranged on the back side of the bedding with respect to the worker, and the edge portion on the front side is pulled. At this time, a high frictional force is generated between the non-slip portion and the surface of the bedding, which facilitates laying in a state where the sheets are not loosened.

In particular, when the sheets are laid on bedding such as a mattress placed on a bed, the non-slip portion may be arranged along the back side surface of the bedding. The rigidity of the non-slip portion is higher than the rigidity of the region of the normal sheet body without the non-slip portion. Therefore, by aligning the non-slip portion along the back side surface of the bedding, the sheet body on the upper surface of the bedding and the non-slip portion on the side surface of the bedding are in a right-angled posture, and when the edge opposite to the non-slip portion is pulled, slipping The stopper is pressed against the side of the bedding. As a result, the frictional force generated between the non-slip portion and the side surface of the bedding increases, and the looseness of the sheets can be reliably eliminated.

(Characteristic composition)
In the sheets according to the present invention, it is convenient that the non-slip portion is provided on the sheet body via an adhesive layer.

(effect)
When a non-slip portion, which is a member separate from the sheet main body, is attached to the sheet main body as in this configuration, the attachment work can be easily and quickly performed by using an adhesive.
In general, many adhesives exhibit a predetermined rigidity when dried. Therefore, when the non-slip portion is adhered to the sheet body, the rigidity of the adhesive layer is added in addition to the rigidity of the cloth material itself as the non-slip portion, and it becomes easy to maintain the flat shape of the non-slip portion as a whole. As a result, the contact property of the non-slip portion with respect to the surface of the bedding is further enhanced, and the sheet laying work can be performed more quickly and reliably.

(Characteristic composition)
In the sheet according to the present invention, a sliding portion made of a material having a lower frictional force than the sheet main body is provided on the central portion of the sheet main body and the surface opposite to the surface facing the bedding. You may keep it.

(effect)
With this configuration, the frictional force generated between the clothes of the user sleeping on the sheets and the sheets is reduced. Therefore, even when the user turns over, both the sliding portion and the non-slip portion function to make it difficult for the laying state of the sheets to be disturbed, and the trouble of re-laying the sheets is reduced.

[First Embodiment]
(Overview)
1 and 2 show the sheets S according to the first embodiment of the present invention.
The sheets S according to the present invention are sheets S that, for example, cover a mattress or a futon, which is bedding 2 laid on the bed 1, only around the position of the user's waist. Normally, the entire bedding 2 is covered with another hanging cloth, and the sheets S of the present embodiment are further laid on the sheets S. The sheets S are made of, for example, a waterproof planar material, and are used as sheets S for coping with incontinence in hospitals, nursing care facilities, and the like.

(Sheets body)
The sheets S of the present embodiment are composed of two parts. One is the sheet main body 3 which forms substantially the entire sheet S. The sheet main body 3 is laid with respect to a part of the bedding 2 in the second direction Y intersecting the longitudinal direction (first direction X) of the bedding 2. The sheet body 3 is made of various waterproof cloth members, a film-like resin material, or the like. In either case, it is preferable that the material is flexible so that it can be washed using a washing machine or the like.

Regarding the dimensions of the sheet body 3, assuming that the dimension along the first direction X of the bedding 2 is the first dimension and the dimension along the second direction Y is the second dimension, usually, the second dimension is relative to the first dimension. Form long. The first dimension is the length from the user's chest to the knee. The second dimension is such that the non-slip portion 4 described later is located on one side surface 2a of the bedding 2, and the opposite edge portion is located on the upper surface surface of the other edge portion of the bedding 2 or the side surface 2a on the opposite side. Let it be the length. However, the dimension is not necessarily limited to this, and any length may be sufficient as long as it can cover at least the upper surface of the bedding 2 along the second direction Y.

(Non-slip part)
In the sheet main body 3, a non-slip portion 4 is provided on at least one of the two edge portions along the second direction Y. 1 and 2 show an example in which the non-slip portion 4 is provided only on one edge portion. The non-slip portion 4 is provided on both sides of the sheet main body 3 facing the bedding 2. FIG. 2 shows a state in which the sheet main body 3 is viewed from the back side. The non-slip portion 4 is made of a material different from that of the sheet main body 3, and in particular, the frictional force against the surface of the bedding 2 is made higher than the frictional force generated by the material of the sheet main body 3. ..

The material constituting the non-slip portion 4 is a cloth material such as a woven fabric or a non-woven fabric, a thin resin film, or the like. It is desirable that the non-slip portion 4 also has flexibility so that it can be easily washed in a washing machine or the like. Materials used include, for example, polyester-based (PET, etc.) and polyamide-based (nylon, etc.) synthetic fibers, cellulose-based and acetate protein-based semi-synthetic fibers, cellulose-based recycled fibers, glass fibers, carbon fibers, and other inorganic fibers. It can be used as a fiber, and in particular, a woven fabric, a knitted fabric, a non-woven fabric, or the like using these ultrafine fibers can be used.

The area of the non-slip portion 4 is an area that can generate a high frictional force with the bedding 2 when one edge portion of the sheet body 3 is pulled. For example, along the first direction X, it is the same as the total width of the sheet body 3, and along the second direction Y, it is, for example, 20 to 30 cm. The dimensions can be appropriately changed depending on the material constituting the non-slip portion 4.

The anti-slip material 4a constituting the anti-slip portion 4 is attached to the sheet main body 3 by, for example, sewing. When the non-slip material 4a floats with respect to the sheet main body 3, it is preferable to form the sewn portions 5 at appropriate intervals. As a result, the integrity of the sheet body 3 and the non-slip material 4a is improved, and the occurrence of wrinkles can be suppressed when the sheet S is laid and when it is used thereafter.

By providing the non-slip portion 4 made of a cloth material or the like on the edge of the sheet main body 3 in this way, the non-slip portion 4 is placed on the surface of the bedding 2 when the sheets S are laid on the bedding 2. It becomes easy to get caught. For example, when laying the sheets S from one side of the bedding 2, the anti-slip portion 4 is arranged on the back side of the bedding 2 with respect to the worker, and the edge portion on the front side is pulled. At this time, a high frictional force is generated between the non-slip portion 4 and the surface of the bedding 2, and the sheets S can be easily laid in a state where the sheets S are not loosened.

In particular, when the sheets S are laid on the bedding 2 placed on the bed 1, the non-slip portion 4 may be arranged along the side surface 2a on the back side of the bedding 2. The rigidity of the non-slip portion 4 is higher than the rigidity of the region of the normal sheet main body 3 in which the non-slip portion 4 is not provided because the anti-slip material 4a is overlapped. Therefore, by aligning the non-slip portion 4 along the side surface 2a on the back side of the bedding 2, the sheet main body 3 on the upper surface of the bedding 2 and the non-slip portion 4 on the side surface 2a are in a right-angled posture with respect to the non-slip portion 4. When pulling the opposite edge, the non-slip portion 4 is pressed against the side surface 2a of the bedding 2. As a result, the frictional force generated between the non-slip portion 4 and the side surface 2a of the bedding 2 increases, and the looseness of the sheets S can be reliably eliminated.

[Second Embodiment]
3 (a) and 3 (b) show the sheets S according to the second embodiment of the present invention. As shown in FIG. 3A, here, the non-slip material 4a is adhered to the sheet main body 3 using an adhesive, and an adhesive layer 6 is formed between the sheet main body 3 and the non-slip material 4a. For example, an adhesive is applied to the entire surface of the non-slip portion 4 material and adhered to the edge portion of the sheet body 3.

As the adhesive, one having a certain degree of viscosity so as not to penetrate between the fibers of the cloth material is used. For example, an adhesive using various polymer materials or rubber-based materials is preferable. Although the adhesive cures to some extent when it dries, it is better to avoid an adhesive that cures to the extent that it becomes difficult to wash it later.

In this way, by attaching the non-slip portion 4 which is a separate member to the sheet main body 3 using an adhesive, the work of attaching the non-slip material 4a becomes easy and quick. In general, many adhesives exhibit predetermined rigidity when dried. Therefore, in addition to the rigidity of the anti-slip material 4a, the rigidity of the adhesive layer 6 is added, and it becomes easy to maintain the planar shape of the entire anti-slip portion 4. As a result, the contact property of the non-slip portion 4 with respect to the surface of the bedding 2 is further enhanced, and the laying work of the sheets S can be performed more quickly and reliably.

Further, as shown in FIG. 3B, in the sheets S of the present embodiment, one non-slip material 4a is adhered with two kinds of adhesives, and the first adhesive layer 61 and the second adhesive layer 62 are adhered to each other. And can also be formed. For example, these adhesives have different rigidity after drying. Of these, the first adhesive having high rigidity after drying is applied to the edge side. A second adhesive having a slightly lower rigidity when dried is applied to the inside of the area to which the first adhesive is applied.

With this configuration, when the sheets S are spread over the bedding 2, the edge portion of the non-slip portion 4 tends to spread in a plane, particularly due to the rigidity of the first adhesive layer 61. Therefore, it is possible to save the trouble of spreading the sheet body 3 on the bedding 2. In addition, the non-slip portion 4 of the sheet body 3 easily comes into contact with the bedding 2 over a wide area. Therefore, when the other edge portion of the sheet main body 3 is pulled toward the laying worker, the frictional force of the non-slip portion 4 is satisfactorily exhibited, and the stretching work of the sheet main body 3 becomes extremely easy.

[Third Embodiment]
FIG. 4 shows the sheets S according to the third embodiment of the present invention. Here, as the anti-slip portion 4, a first anti-slip material 41a and a second anti-slip material 42a having different frictional forces that can be generated are used. If the frictional force of the first anti-slip material 41a is superior, the first anti-slip material 41a is installed on the side close to the edge of the sheet main body 3. Members that generate high frictional force and members with low frictional force are provided in this order. By doing so, it becomes easy to always maintain the shape of the edge portion of the sheets S flat, and it is possible to obtain a beautiful laid state without wrinkles over the entire surface of the sheets S.

The first anti-slip material 41a and the second anti-slip material 42a may be fixed to the sheet body 3 by either sewing or adhesion. When an adhesive is used, the same adhesive may be used for the first anti-slip material 41a and the second anti-slip material 42a, or different adhesives may be used. The adhesive may be selected in consideration of how the rigidity after applying the adhesive in each of the non-slip portions 4 is determined.

[Fourth Embodiment]
FIG. 5 shows the sheets S according to the fourth embodiment of the present invention. The sheets S of the present embodiment reduce the frictional force generated between the clothes of the user sleeping on the sheets S and the sheets S, and the state of the sheets S once laid changes the sleeping appearance of the user. It is also difficult to disturb. Therefore, in the present embodiment, in addition to providing the non-slip portion 4 on the edge of the sheet body 3 facing the bedding 2, the central portion of the sheet body 3 facing the bedding 2 On the opposite surface, a sliding portion 7 made of a material having a lower frictional force than the sheet main body 3 is provided.

The sliding portion 7 may be provided only in the vicinity of the central portion of the bedding 2 along the second direction Y, which is particularly likely to come into contact with the user, or may be provided on the entire surface of the sheet main body 3. When provided on the entire surface, the anti-slip material 4a and the slip material 7a are arranged so as to be overlapped with the sheet main body 3 sandwiched at the edge of the sheet main body 3.

As the sliding material 7a constituting the sliding portion 7, a resin film or the like can be used in addition to various cloth materials. However, a material having flexibility that can follow the deformation of the sheet body 3 is preferable. The sliding material 7a may be attached to the sheet body 3 by any method such as sewing or adhesion.

With the sheets S having this configuration, even if the user turns over, both the sliding portion 7 and the non-slip portion 4 function to make it difficult for the laying state of the sheets S to be disturbed, and the sheets S are re-laid. The time and effort can be reduced.

[Other Embodiments]
The non-slip portion 4 of the present invention is not only provided on one edge of the sheet body 3, but may be provided on each of the two opposing edges. With such a configuration, it is not necessary to pay attention to the direction of the sheets S when laying the sheets S. Further, after laying, both anti-slip portions 4 exert a high frictional force on the surface of the bedding 2, so that the sheets S can be used so that the laid state is not easily disturbed.

The sheets according to the present invention can be widely applied as sheets to be laid in a part of an area such as a bed or a futon.
