Description

[Technical field]

[0001] The present invention relates to a sheet for a mat that is easy to attach or remove, and a method for attaching or removing the sheet to or from a mat. [Background technology]

[0002] (Prior Art) Nowadays, the number of nursing care facilities is increasing, and the number of nursing care beds used in these facilities is also increasing. This bed is equipped with a mattress, and when used by a person receiving care (including a patient, etc.), the mattress is entirely covered with a sheet. The mat sheets are replaced with new ones periodically or when soiled. In changing the sheets, the sheet needs to be attached to or removed from the mat, but the more physically disabled the person being cared for is, the more troublesome this task becomes.

[0003] Conventional sheets for mattresses are made of a single cloth sheet, and therefore require work to cover the surface and four side surfaces of the mattress (Patent Document 1). In this case, after the sheet has covered the sides, it is wrapped (i.e. rolled) onto the back side of the mat. In this operation, after wrapping one side of the mat, for example the head side, with the sheet, the opposite side, the foot side, is wrapped while pulling it so as not to cause wrinkles. This causes the sheets to shift and tend to slip out from the part of the mattress that is wrapped around the head of the bed. For this reason, sheets have been provided that have a pocket portion for storing the head portion of the mattress.

[0004] However, when changing the sheets from the mat when the cared person is lying on the mat, it is necessary to first stand the cared person up and lift him / her off the mat. This is because it is necessary to first place the bag part over the head side, i.e., the short side, of the rectangular mat, and then to place the sheet A over the foot side of the mat.

[0005] In this case, for example, the bed is made fully flat, and the care recipient is temporarily lifted off the mattress. If the person being cared for is heavy, two caregivers (attendants) will lift the person up while another person changes the sheets. In changing the sheets, first remove the sheet from the foot area, then remove the sheet bag from the top of the mattress.

[0006] When installing it the other way around, the person being cared for is lifted up and the sheet is attached starting from the head side, i.e. the bag part of the sheet is placed over the head part of the mat, and then the sheet is spread out towards the feet, wrapping around the sides to cover them. Therefore, it is extremely troublesome to have to lift the cared person off the mat at least once.

[0007] For this reason, it is understandable that it would be extremely convenient if the person being cared for could change the sheets without having to leave the mattress. However, such sheets have not yet been provided. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Utility model registration No. 3215840 Summary of the Invention [Problem to be solved by the invention]

[0009] As a result of extensive research into the technical background of such nursing beds, the inventors have focused on the directionality when removing (that is, removing) the sheet A from the rectangular parallelepiped mattress B. And, by removing sheet A sideways, that is, from left to right (or right to left), rather than from the head to the feet, they unexpectedly discovered that it is no longer necessary to lift up the person being cared for, meaning that sheet A can be changed without the person being cared for leaving mat B. The present invention was made based on this finding. [Means for solving the problem]

[0010] Thus, the object of the present invention is to provide a mat sheet that can be replaced without the cared for person leaving the mat B, and to provide a method for attaching sheet A to the mat B and a method for removing sheet A from the mat B.

[0011] That is, the present invention provides: (1) The sheet A is attached to a rectangular parallelepiped mat B, and comprises a bag portion A1 for storing a vertical end region B1 on one long side of the mat B, and a mat cover portion A2 extending from the bag portion A1. The sheet A comprises a rectangular surface portion 1, a left extension portion 2 and a right extension portion 3 extending from the long side of the surface portion 1, and a head extension portion 4 and a foot extension portion 5 extending from the short side of the surface portion 1. The edges of the left extension portion 2 and the head extension portion 4 are The line of the left extension 2 and the ridge line of the foot extension 5 are sewn together to form a bag portion A1. The left extension 2 is made up of a rectangular side contact portion 21 and a trapezoidal back contact portion 22 having two inclined sides. The head extension 4 is made up of a rectangular side contact portion 41 and a trapezoidal back contact portion 42 having one inclined side. The foot extension 5 is made up of a rectangular side contact portion 51 and a trapezoidal back contact portion 52 having one inclined side. It is found in mattress sheets.

[0014] The present invention also provides a method for producing a semiconductor device comprising the steps of: 2 ), the angles θ1 and θ3 of the inclined sides of the back surface contact portion 22 of the left extension portion 2, the angle θ2 of the inclined side of the back surface contact portion 42 of the head extension portion 4, and the angle θ4 of the inclined side of the back surface contact portion 52 of the foot extension portion 5 are each 45 degrees. 1 ) The present invention relates to the mat sheet described in the above.

[0015] The present invention also provides a method for producing a semiconductor device comprising the steps of: 3 ), the angle θ2 of the inclined side of the back surface contact portion 42 of the head extension portion 4 is smaller than the angle θ1 of the inclined side of the back surface contact portion 22 of the left extension portion 2, and the angle θ4 of the inclined side of the back surface contact portion 52 of the foot extension portion 5 is smaller than the angle θ3 of the inclined side of the back surface contact portion 22 of the left extension portion 2. 1 ) The present invention relates to the mat sheet described in the above.

[0016] The present invention also provides a method for producing a semiconductor device comprising the steps of: 4 ), The angles θ1 and θ3 of the inclined sides of the back surface contact portion 22 of the left extension portion 2, the angle θ2 of the inclined side of the back surface contact portion 42 of the head extension portion 4, and the angle θ4 of the inclined side of the back surface contact portion 52 of the foot extension portion 5 are θ1+θ2>90 degrees (θ1=θ2), θ3+θ4>90 degrees (θ3=θ4). The above ( 1 ) The present invention relates to the mat sheet described in the above.

[0017] The present invention also provides a method for producing a semiconductor device comprising the steps of: 5 ), The angles θ1 and θ3 of the inclined sides of the back surface contact portion 22 of the left extension portion 2, the angle θ2 of the inclined side of the back surface contact portion 42 of the head extension portion 4, and the angle θ4 of the inclined side of the back surface contact portion 52 of the foot extension portion 5 are θ1 + θ2 < 90 degrees (θ1 = θ2), and θ3 + θ4 < 90 degrees (θ3 = θ4) as described above in (1).The present invention relates to a sheet for a mat. Effect of the Invention

[0018] 1) The present invention relates to a sheet A to be attached to a rectangular mat B, which comprises a bag portion A1 that stores a vertical end region portion B1 on one long side of the mat B, and a mat cover portion A2 extending from the bag portion A1. Therefore, the sheet A can be attached to the mat B from the side, and there is no need to lift the cared person off the mat B. Furthermore, the care recipient only needs to rotate sideways, which reduces the physical burden on the body. Only one caregiver can change sheet A. After the bag portion A1 of the sheet A is stored in the longitudinal end region B1 of the mat B, the mat cover portion A2 can be pulled laterally to cover the remaining portion of the mat B.

[0019] 2) In addition, in the present invention, sheet A comprises a rectangular surface portion 1, a left extension portion 2 and a right extension portion 3 extending from the long sides of surface portion 1, and a head extension portion 4 and a foot extension portion 5 extending from the short sides of surface portion 1, and the ridge lines of the left extension portion 2 and the head extension portion 4 are sewn together, and the ridge lines of the left extension portion 2 and the foot extension portion 5 are sewn together to form a bag portion A1. Therefore, the vertical end region portion B1 on one of the long sides of mat B is stored in the space formed by the left extension portion 2, the head extension portion 4, and the foot extension portion 5, so that sheet A does not shift sideways even if surface portion 1 is pulled laterally.

[0020] 3) Furthermore, in the present invention, the left extension 2 consists of a rectangular side abutment portion 21 and a trapezoidal back abutment portion 22 having two inclined sides, the head extension 4 consists of a rectangular side abutment portion 4 and a trapezoidal back abutment portion 42 having one inclined side, and the foot extension 5 consists of a rectangular side abutment portion and a trapezoidal back abutment portion having one inclined side.Therefore, the side abutment portion of the left extension 2, the side abutment portion of the head extension 4, and the side abutment portion of the foot extension 5 cover the side of the vertical end region B1 of the mat B, and the back abutment portion of the left extension 2, the back abutment portion of the head extension 4, and the back abutment portion of the foot extension 5 cover the back surface of the vertical end region B1.

[0021] 4) Furthermore, in the present invention, the angles θ1 and θ3 of the inclined sides of the back surface abutment portion 22 of the left extension portion 2, the angle θ2 of the inclined side of the back surface abutment portion 42 of the head extension portion 4, and the angle θ4 of the inclined side of the back surface abutment portion 52 of the foot extension portion 5 are all 45 degrees, so that a rectangular storage section is formed and the vertical end region portion B1 of the rectangular parallelepiped can be accurately stored in the bag portion A1.

[0022] 5) Furthermore, in the present invention, the angle θ2 of the inclined side of the back surface abutment portion 42 of the head extension portion 4 is smaller than the angle θ1 of the inclined side of the back surface abutment portion 22 of the left extension portion 2, and the angle θ4 of the inclined side of the back surface abutment portion 52 of the foot extension portion 5 is smaller than the angle θ3 of the inclined side of the back surface abutment portion 22 of the left extension portion 2. Therefore, the amount (length) of the back surface abutment portion 22 of the left extension portion 2 enveloping the back surface of the mat is greater than the amount (length) of the back surface abutment portion 42 of the head extension portion 4 and the back surface abutment portion 52 of the foot extension portion 5 enveloping the back surface of the mat, and the space in the bag portion for storing the mat is larger. Incidentally, the larger the angles θ1 and θ3 of the inclined sides are, the larger the amount of wrapping of the rear surface abutting portion 22 of the left extension portion 2 with the rear surface of the mat can be.

[0023] 6) Furthermore, the present invention provides a method for attaching a sheet A to a rectangular parallelepiped mat B, which comprises a bag portion A1 for storing a vertical end region B1 on one long side of the mat B and a mat cover portion A2 extending from the bag portion A1. First, the bag portion A1 of the sheet A is placed over the vertical end region B1 on one long side of the mat B to store the vertical end region B1 in the bag portion A1, and then the mat cover portion A2 is spread over and wrapped around the part of the mat B other than the vertical end region B1 of the mat B to attach the sheet A. This allows the sheet A to be attached to the mat B from the side while the person being cared for is lying in bed, and there is no need to take the trouble of lifting the person being cared for off the mat B. Furthermore, the care recipient only needs to rotate sideways, which reduces the physical burden on the body. Only one caregiver can change sheet A.

[0024] 7) Furthermore, the present invention provides a method for removing a sheet A from a rectangular parallelepiped mat B, which consists of a bag portion A1 that stores a vertical end region B1 on one long side of the mat B and a mat cover portion A2 extending from the bag portion A1.First, the mat cover portion A2 of the sheet A is removed from a part of the mat B other than the vertical end region B1 of the mat B, and then the bag portion A1 is detached from the vertical end region B1 on one long side of the mat B and removed.Therefore, the sheet A can be removed from the mat B from the side while the cared for person is lying in bed, and there is no need to take the trouble of lifting the cared for person off of the mat B. Furthermore, the care recipient only needs to rotate sideways, which reduces the physical burden on the body. Only one caregiver can change sheet A. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] (First embodiment) The sheet A for a mat of the present invention is made of a cloth body and can be very easily attached to and detached from a mat B used in a bed. There are various types of mats B to which the attachment is applied, but the present invention is preferably applied to mats B used mainly in nursing care beds. The mattress B for this bed has a certain thickness and is rectangular, i.e., a cuboid, consisting of long and short sides when viewed from above. The person being cared for usually lies down vertically, i.e., along the long side of the mattress B.

[0027] FIG. 1 is a diagram showing a blank, i.e., an unfolded state, of a sheet A according to a first embodiment before sewing. In the following drawings, the sheet A is depicted as having a flat surface for the sake of convenience, but in reality it is a flexible cloth body. FIG. 2 is a perspective view showing a rectangular parallelepiped mat B to which the sheet A is attached, illustrating the position of a longitudinal end region B1 on one of the long sides. Here, the longitudinal end region B1 of the mat B is a three-dimensional portion to be inserted into the bag portion A1 of the sheet A. Moreover, Figure 3 shows the three-dimensional shape of sheet A after sewing as viewed from the back, where A) shows the state in which the right extension portion 3 has not yet been wrapped, and B) shows the state in which sheet A has been attached by wrapping around the entire mat. FIG. 4 shows the state in which the sheet A is attached to the entire mat, where A) shows the state as seen from the back side, and B) shows the state as seen from the front side.

[0028] The sheet A for a mat of the present invention is configured so as to be attached to a mat B which has a certain thickness and is rectangular (i.e., a rectangular prism) consisting of long and short sides when viewed from above, and consists of a bag portion A1 and a mat cover portion A2 extending from the bag portion A1. More specifically, it comprises a bag portion A1 for storing a longitudinal end region B1 located on one side (long side) of the mat B, and a mat cover portion A2 extending from the bag portion A1.

[0029] In the blank of FIG. 1, each side, b1 and b2, c1 and c2, d1 and d2, e1 and e2, f1 and f2, g1 and g2, and h1 and h2, are the same length. The bag portion A1 is formed by sewing together parts of the entire periphery of this flat blank (b1 and e1, c1 and d1, b2 and e2, c2 and d2).

[0030] The blank is described in more detail below. In this blank, sheet A has a rectangular (oblong) surface portion 1 located in the center, a left extension portion 2 extending from the left long side of surface portion 1, and a right extension portion 3 extending from the right long side of surface portion 1. Furthermore, it is provided with a head extension portion 4 extending from the head short side of the surface portion 1 and a foot extension portion 5 extending from the foot short side of the surface portion 1.

[0031] Then, the ridgeline of the left extension portion 2 and the head extension portion 4 are sewn together, and the ridgeline of the left extension portion 2 and the foot extension portion 5 are sewn together, thereby forming a bag portion A1 having a storage space S. The longitudinal end region B1 of the mat B is accommodated in the accommodation space S of this bag portion A1 (see Figs. 2 and 4). The vertical end area B1 on the long side of the mattress B is stored in the storage space S defined by the left extension 2, the head extension 4, and the foot extension 5, so even if the surface part 1 is pulled to the right, the sheet A does not shift horizontally because it is fixed by the bag part A1. Therefore, vertical wrinkles are unlikely to occur.

[0032] In addition, the left extension 2 consists of a rectangular side abutment portion 21 and a trapezoidal back abutment portion 22 having two inclined sides, the head extension 4 consists of a rectangular side abutment portion 41 and a trapezoidal back abutment portion 42 having one inclined side, and the foot extension 5 consists of a rectangular side abutment portion 51 and a trapezoidal back abutment portion 52 having one inclined side.

[0033] The right extension 3 is made up of a rectangular side contact portion 31 and a rectangular back contact portion 32 . Here, each side contact portion is a portion that contacts the side surface (i.e., side wall surface) of mat B, and each back surface contact portion is a portion that is wrapped around (i.e., wrapped around) the back surface of mat B and contacts it. The side surface abutment portion 21 of the left extension portion 2, the side surface abutment portion 41 of the head extension portion 4, and the side surface abutment portion 51 of the foot extension portion 5 cover the side surface of the vertical end region B1 of the mat B, and the back surface abutment portion 22 of the left extension portion 2, the back surface abutment portion 42 of the head extension portion 4, and the back surface abutment portion 52 of the foot extension portion 5 cover the back surface of the vertical end region B1 of the mat B.

[0034] The sum of the angle θ1 of the inclined side of the back surface contact portion 22 of the left extension portion 2 and the angle θ2 of the inclined side of the back surface contact portion 42 of the head extension portion 4 is 90 degrees (θ1+θ2=90 degrees). The sum of the angle θ3 of the inclined side of the back surface contact portion 22 of the left extension portion 2 and the angle θ3 of the inclined side of the back surface contact portion 52 of the foot extension portion 5 is 90 degrees (θ3+θ4=90 degrees).

[0035] In Figure 1, the angles θ1 and θ3 of the inclined sides of the back surface abutment portion 22 of the left extension portion 2, the angle θ2 of the inclined side of the back surface abutment portion 42 of the head extension portion 4, and the angle θ4 of the inclined side of the back surface abutment portion 52 of the foot extension portion 5 are each shown to be 45 degrees (θ1 = θ2 = θ3 = θ4 = 45 degrees). In this case, the shape of the storage space S of the bag portion A1 formed is a uniform and accurate rectangular parallelepiped, so that the end portion of the rectangular parallelepiped mat B can be stored with as little gap as possible. That is, the size of the bag portion A1 (see Figs. 3 and 4) is exactly such that it can accommodate and cover the longitudinal end region B1 of the mat B.

[0036] When the entire sheet becomes three-dimensional, it is large enough to cover the entire mat B (except for part of the back side). The bag portion A1 has a storage space S with a thickness t, a long side l, and a short side (width) w, and the vertical end region B1 (thickness T1, long side L1, short side (i.e. width) W1), which is part of the mat B, is completely stored inside. The longitudinal end region B1 of the mat B is covered by this bag portion A1, and the remaining portion of the mat B other than the longitudinal end region B1 is covered by the mat covering portion A2.

[0037] Here, when mat B is an air mat or the like, an air supply pipe is usually connected to mat B, and therefore it is necessary to secure a passage for this supply pipe. In the sheet A of the present invention, the ridge lines h1 and g1 of the right extension portion 3 and the head extension portion 4 are not sewn together, so that the sheet A can be opened even after being attached to the mat B. Similarly, the ridges h2 and g2 of the right extension 3 and the foot extension, respectively, are not sewn, so that they can be opened even after the sheet A is attached. In this way, the supply pipe, etc. can be easily routed through the opening at the right head or foot of the sheet A.

[0038] Since the sheet A of the present invention has the above-mentioned structure, it is extremely convenient to attach it to or detach it from the mat B. Next, the installation or removal operation (task) will be described. (How to attach sheet A to mat B) Here, the sheet A will be described as having a pocket portion A1 on the left side, that is, a sheet A having a pocket portion A1 for accommodating a longitudinal end region portion B1 on the left side of a mat B. Assume that the sheet A of the present invention is attached to a bare mat B.

[0039] 1) First, the longitudinal end region B1 on one long side of the mat B is covered with the bag portion A1 of the sheet A, and the longitudinal end region B1 is stored in the bag portion A1. As a result, the longitudinal end region B1 of the mat B is stored in the storage space S defined by the bag portion A1 of the sheet A.

[0040] 2) Thereafter, the mat covering portion A2 is spread over the mat B other than the longitudinal end region portion B1, and is attached by wrapping the mat covering portion A2. In this case, the excess part of sheet A hangs down from the underside of mat B, and the excess hanging part is wrapped around the back side of mat B. During this operation, even if the mat covering portion A2 is pulled laterally to the right so as not to cause wrinkles, the sheet A will not slip out of place because it is fixed to the mat B by the bag portion A1. Here, if a part of the sheet A is provided with an adhesive portion, it is convenient because the sheet A can be fixed securely to the mat B.

[0041] (How to attach Sheet A to the person being cared for) Next, a method of attaching sheet A to bare mattress B when a person being cared for is lying down on a bed will be described.

[0042] FIG. 5 is an explanatory diagram showing a schematic method of attaching a sheet A to a mat B when a care recipient is lying on the bed. For the sake of convenience, the people being cared for are shown as pictograms. The sheet A used in this case is assumed to be the sheet A having the pocket portion A1 formed on the left side as described in the first embodiment. First, the person being cared for () is lying in the center position on a fully flat, bare mat B (see (A)).

[0043] 1) First, the person being cared for moves his / her body from the center of mat B to the right (i.e., the right half) (see (B)). In this case, the person being cared for can easily move sideways by simply rotating to the right (i.e., rotating to the left when the person being cared for is used as the reference), and there is no need to sit up at all. Of course, it is also possible to move by sliding your body to the right. The lateral movement is performed in order to cover the longitudinal end region B1 on the left long side of the mat B with the sheet A for storage. Since the person being cared for is lying vertically on the right side of the center, there is nothing above the left side area of ​​Mat B. This makes it possible to place the bag portion A1 (see Figs. 3 and 4) of the sheet A over the longitudinal end region B1 on the left long side of the mat B to encase it.

[0044] 2) Next, the bag portion A1 of the sheet A is placed over the longitudinal end region B1 on the left long side of the mat B and stored (see (C)). In this case, it is preferable that the sheet A is placed so as to encase not only the longitudinal end region B1 of the mat B but also the center portion of the mat B.

[0045] 3) Next, the person being cared for rotates to the left, moving laterally to the left half of mat B (see (D)). The person being cared for is lying on the right side of the center of mat B, and by rotating to the left, he or she moves to the left half of mat B, which is already covered with sheet A.

[0046] 4) Then, spread the mat cover A2 to cover the right half of mat B (the area to the right of the center line). Cover the body with sheet A (see (E)). Now, the entire area of ​​Mat B is covered with Sheet A and Sheet A is completely attached to Mat B.

[0047] 5) Next, the person being cared for rotates to the right and places his / her body back in the center of Mat B (see (F)). The care recipient is now back in his or her original lying position.

[0048] As already mentioned, during installation, the ventilation pipes, electric wires, etc. can be allowed to escape. As described above, the person being cared for does not need to remove his / her body from the mat at all. In terms of bodily movement, the person being cared for does not need to leave Mat B, but simply moves by turning the body laterally, that is, to the left (or right), which places an extremely small burden on the person. Next, the case where sheet A is removed will be described.

[0049] (How to remove sheet A from mat B) Here, the sheet A will be described as having a pocket portion A1 on the left side, that is, a sheet A having a pocket portion A1 that houses a longitudinal end region portion B1 on the left side of a mat B. Also, assume that sheet A is to be removed from mat B to which sheet A is already attached.

[0050] 1) First, the mat covering portion A2 of the sheet A is removed from the mat B other than the longitudinal end region B1 of the mat B.

[0051] 2) After that, the bag portion A1 is separated from the longitudinal end region B1 on one long side of the mat B and removed. Now the entire sheet A has been removed from mat B.

[0052] (How to remove sheet A from the person being cared for) The sheet A used in this case is the sheet A having the pocket portion A1 formed on the left side as described in the first embodiment.

[0053] FIG. 6 is an explanatory diagram that shows a schematic diagram of a method for removing a sheet A from a mat B when a care recipient is lying on the bed. Now, assume that the person being cared for is lying down on mat B in any position, for example in the center position (see (A)).

[0054] 1) First, the person being cared for is moved from the center of mat B to the left (left half) (see (B)). In this case, the person being cared for can easily move sideways by simply rotating to the left (or to the right when the person being cared for is used as the reference point), and there is no need to sit up at all.

[0055] 2) Next, remove the right half of sheet A from the bed and fold it toward the center (see (C)). In this case, the right half of sheet A, which is the opposite side to where the person being cared for has moved, becomes empty, so that part of sheet A is folded and pushed towards the center.

[0056] 3) Next, the person being cared for moves laterally to the right half of mat B by rotating to the right (see (D)). The person being cared for starts lying on the left side of the center, and by rotating to the right, moves to the right half of bare mat B, which is now not covered by sheet A. Now, since there is nothing on the area of ​​sheet A to the left of the center of mat B, sheet A can be removed as is.

[0057] 4) Next, remove the bag portion A1 of the sheet A from the longitudinal end region B1 on the left long side of the mat B (see (E)). Now, sheet A can be removed from all areas of mat B. Next, the person being cared for rotates to the left and places his / her body back in the center position of Mat B (see (F)). The care recipient is now back in his or her original lying position.

[0058] The above has been described with respect to sheet A having a bag portion A1 on the left side, i.e., sheet A equipped with a bag portion A1 that stores the vertical end region B1 on the long side of the left side of mat B. However, if the intended sheet A is sheet A having a bag portion A1 on the right side, i.e., sheet A equipped with a bag portion A1 that stores the vertical end region B1 on the long side of the right side of mat B, then the operations described above can be reversed.

[0059] (Second embodiment) A modification of the first embodiment will be described below. Figure 7 shows a sheet A of the second embodiment, where Figure 7(A) shows the blank before sewing, and Figure 7(B) shows the three-dimensional shape after sewing as viewed from the back, with the right extension portion 3 not yet wrapped. The length H2 of the rear surface contact portion 42 of the head extension portion 4 and the length H3 of the rear surface contact portion 52 of the foot extension portion 5 are smaller than those in the first embodiment described above. The length H1 of the rear surface abutment portion 22 of the left extension portion 2 is the same as that of the first embodiment. In other words, the angles (θ1, θ3) of the inclined sides of the back surface abutment portion 22 of the left extension portion 2, the angle θ2 of the inclined sides of the back surface abutment portion 42 of the head extension portion 4, and the angle θ4 of the inclined sides of the back surface abutment portion 52 of the foot extension portion 5 are different from those of the first embodiment. Furthermore, θ1+θ2=90 degrees and θ3+θ4=90 degrees.

[0060] The angle θ2 of the inclined side of the back surface contact portion 42 of the head extension portion 4 is smaller than the angle θ1 of the inclined side of the back surface contact portion 22 of the left extension portion 2 (θ1>θ2). In addition, the angle θ4 of the inclined side of the back surface contact portion 52 of the foot extension portion 5 is smaller than the angle θ3 of the inclined side of the back surface contact portion 22 of the left extension portion 2. (θ3>θ4). In such a sheet A, the amount of wrapping of the back surface contacting portion 22 of the left extension portion 2 onto the back surface of the mattress is smaller than the amount of wrapping of the back surface contacting portion 42 of the head extension portion 4 and the back surface contacting portion 52 of the foot extension portion 5 onto the back surface of the mattress.

[0061] For example, the greater the angle difference, ie, the smaller the angle θ2 is than the angle θ1, the smaller the back surface contact portion 42 of the head extension portion 4 becomes compared to the back surface contact portion 22 of the left extension portion 2. The same applies to the relationship between the angles θ3 and θ4.

[0062] Since the sheet A of the invention can prevent lateral shifting by storing the vertical end region B1 on the long side of the mat B, the amount of wrapping of the back surface abutting portion 42 of the head extension portion 4 and the back surface abutting portion 52 of the foot extension portion 5 onto the back surface of the mat can be made small in this way from the standpoint of fabric costs.

[0063] In this embodiment, the smaller the angle θ2 of the inclined side, the smaller the amount of wrapping of the back surface abutment portion 42 of the head-side extension portion 4, and similarly, the smaller the angle θ4 of the inclined side, the smaller the amount of wrapping of the back surface abutment portion 52 of the foot-side extension portion 5 with the back surface of the mat. Incidentally, in FIG. 7, b1 and e1, and b2 and e2 have the same length, and the bag portion A1 is formed by sewing these together (for the reference symbols, see FIG. 1).

[0064] (Third embodiment) Figure 8 shows a sheet A of the third embodiment, where Figure 8(A) shows the blank before sewing, and Figure 8(B) shows the three-dimensional shape after sewing as viewed from the back, with the right extension portion 3 not yet wrapped. The length H1 (the distance between the bottom side and the top side) of the rear surface abutment portion 22 of the left extension portion 2 is different from that of the first embodiment described above. The length H2 of the rear surface contact portion 42 of the head extension portion 4 and the length H3 of the rear surface contact portion 52 of the foot extension portion 5 are the same as those in the first embodiment. In other words, the angles (θ1, θ3) of the inclined sides of the back surface abutment portion 22 of the left extension portion 2, the angle θ2 of the inclined sides of the back surface abutment portion 42 of the head extension portion 4, and the angle θ4 of the inclined sides of the back surface abutment portion 52 of the foot extension portion 5 are each different from the first embodiment. Furthermore, θ1+θ2=90 degrees and θ3+θ4=90 degrees.

[0065] The angle θ2 of the inclined side of the back surface contact portion 42 of the head extension portion 4 is smaller than the angle θ1 of the inclined side of the back surface contact portion 22 of the left extension portion 2 (θ1>θ2). In addition, the angle θ4 of the inclined side of the back surface contact portion 52 of the foot extension portion 5 is smaller than the angle θ3 of the inclined side of the back surface contact portion 22 of the left extension portion 2. (θ3>θ4). In such a sheet A, the volume of the bag portion A1 is large, and therefore the space for storing the longitudinal end region B1 of the mat is large. In this embodiment, the smaller the angle θ2 or angle θ4 of the inclined side is, the larger the angle θ1 or angle θ3 of the inclined side is, and the larger the volume of the bag portion A1 is, and the larger the space for storing the longitudinal end region B1 of the mat is.

[0066] For example, the greater the difference in angles, that is, the smaller the angle θ2 is than the angle θ1, the larger the rear contact portion 22 of the leftward extension 2 will be compared to the rear contact portion 42 of the cranial extension 4. The same applies to the relationship between the angles θ3 and θ4.

[0067] The sheet A of the invention is capable of preventing lateral shifting by storing the vertical end region B1 on the long side of the mat B, but by using the present embodiment as described above, the vertical end region B1 on the long side of the mat B becomes larger, which more effectively prevents the sheet A from shifting vertically.

[0068] Incidentally, in FIG. 8, b1 and e1, and b2 and e2 have the same length, and the bag portion A1 is formed by sewing these together (for the reference symbols, see FIG. 1).

[0069] (Fourth embodiment) In the embodiment described above, the sum of the angle θ1 of the inclined side of the back surface abutment portion 22 of the left extension portion 2 and the angle θ2 of the inclined side of the back surface abutment portion 42 of the head extension portion 4 was 90 degrees, but as in this embodiment, it is also possible for it to be greater than 90 degrees, i.e., θ1 + θ2 > 90 degrees (θ1 = θ2).

[0070] 9 shows a part of the blank before sewing in the fourth embodiment. The angle shown by the broken line is 45 degrees or more. Similarly, the sum of the angle θ3 of the inclined side of the back surface abutment portion 22 of the left extension portion 2 and the angle θ4 of the inclined side of the back surface abutment portion 52 of the foot extension portion 5 was 90 degrees, but it is also possible for it to be greater than 90 degrees, i.e., θ3 + θ4 > 90 degrees (θ3 = θ4). In these cases, if the length H2 (distance between the bottom and top sides) of the back surface abutment portion 42 of the head extension portion 4, the length H1 of the back surface abutment portion 22 of the left extension portion 2, and the length H3 of the back surface abutment portion 52 of the foot extension portion 5 are equal, the sum of the lengths of f1, a, and f2 will be larger than in the first embodiment (see Figure 9 (B)). Therefore, when attaching the bag portion A1 of the sheet A to the longitudinal end region B1 of the mat B, it is easy to cover it.

[0071] (Fifth embodiment) In this embodiment, the sum of the angle θ1 of the inclined side of the back surface abutment portion 22 of the left extension portion 2 of the base embodiment and the angle θ2 of the inclined side of the back surface abutment portion 42 of the head extension portion 4 can be less than 90 degrees, i.e., θ1 + θ2 < 90 degrees (θ1 = θ2).

[0072] 10 shows a part of the blank before sewing in the fifth embodiment. The angle shown by the broken line is less than 45 degrees. Similarly, the sum of the angle θ3 of the inclined side of the back surface abutment portion 22 of the left extension portion 2 and the angle θ4 of the inclined side of the back surface abutment portion 52 of the foot extension portion 5 can be less than 90 degrees, i.e., θ3 + θ4 < 90 degrees (θ3 = θ4).

[0073] In these cases, if the length H2 (distance between the bottom and top sides) of the back surface abutment portion 42 of the head extension portion 4, the length H1 of the back surface abutment portion 22 of the left extension portion 2, and the length H3 of the back surface abutment portion 52 of the foot extension portion 5 are equal, the sum of the lengths of f1, a, and f2 will be smaller than in the first embodiment (see Figure 9(C)). Therefore, after the bag portion A1 of the sheet A is placed over the longitudinal end region B1 of the mat B, a tightening effect is produced. Usually, mat B has some flexibility, so that the edge of sheet A can act to tighten mat B.

[0074] For reference, Figure 11 is a schematic cross-sectional view explaining the relationship between the longitudinal end region B1 of the mat B and the bag portion A1 of the sheet A in Figure 11(A) of the first embodiment, Figure 11(B) of the fourth embodiment, and Figure 11(C) of the fifth embodiment. It can be seen that Figure 11(A) shows the relationship in the first embodiment, where mat B is stored snugly and accurately in bag portion A1, Figure 11(B) shows the relationship in the fourth embodiment, where bag portion A1 stores mat B with room to spare, and Figure 11(C) shows the relationship in the fifth embodiment, where bag portion A1 stores mat B in a squeezed manner.

[0075] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments.

[0076] For example, the length (the distance between the bottom side and the top side) of the back surface contact portion 42 of the head extension portion 4 can be made shorter or longer than the back surface contact portion 52 of the foot extension portion 5. As a matter of course, the amount of the right extension 3 enveloping the back surface of the mat can also be made longer. Moreover, corners other than those forming the bag portion A1 may or may not be rounded.

[0077] In addition, the term "cuboid" used in the specification does not necessarily mean a rectangular parallelepiped, but may mean any shape having a rectangular parallelepiped shape, and the same applies to shapes such as rectangle, oblong, and trapezoid. In addition, if the periphery of this right extension 3 is treated with a non-slip resin (such as silicone resin) or anti-slip tape (such as silicone resin tape) is attached, it will be more effective in preventing the sheet A from slipping when it is wrapped around the back side of the mat B. It is also preferable to sew bias tape to the seam with sewing thread in terms of strength and prevention of unraveling (overlock stitch). It is also possible to provide gussets at the seams. As the fabric body of the sheet A, knitted fabric (warp knitted fabric, weft knitted fabric, etc.), woven fabric, nonwoven fabric, etc. are appropriately used.

[0078] Materials that can be used include synthetic resins such as polyester and polyamide, natural fibers such as cotton, wool and silk, and man-made fibers such as rayon, and mixtures of these are also possible. From the viewpoint of SGDS, the yarn constituting the fabric body is preferably made of a material that can be put into a recycling process, such as polyethylene terephthalate. Ultimately, this can contribute to saving resources and preventing carbon dioxide emissions. As the mat B, a mat for nursing care or nursing use is preferably used, but other mats B are also applicable. [Industrial Applicability]

[0079] The sheet A of the present invention is extremely easy to use for the caregiver or the person being cared for, as it places less physical strain on them. It is preferably used as a bed mat for a care recipient, but it can also be applied to other bed mats for nursing or for physically disabled people. [Explanation of symbols]
