Description

[Technical field]

[0001] The present invention relates to bedding. [Background technology]

[0002] In today's information society, we are constantly supplied with a huge amount of information in our daily lives and work, which enriches our lives and improves the quality of our work. However, this society is also sometimes referred to as a stressful one, in which people are prone to stress due to the high level of quality required in both life and work.

[0003] One way to relieve this stress is sleep, so it is important to improve the quality of sleep.

[0004] In order to improve the quality of sleep, it is important to improve the quality of the bedding used while sleeping, such as the bed and mattress. For example, Non-Patent Document 1 below describes bedding on the market that claims to improve sleep quality. [Prior art documents] [Non-patent literature]

[0005] [Non-Patent Document 1] https: / / sleep.airweave.jp / category / MATTRESS_PAD / Summary of the Invention [Problem to be solved by the invention]

[0006] On the other hand, in daily life, there are various factors that cause chronic stiffness and tension, such as maintaining a similar posture for a certain period of time or adopting an unnatural posture, and it is very important to eliminate the chronic stiffness and tension caused by these factors, and to correct the bones if they have shifted from their normal position.

[0007] However, the technology described in Patent Document 1 merely aims to reduce the burden on the body, and does not propose reduction as described above.

[0008] In view of the above problems, the present invention aims to provide bedding that improves sleep quality and the effect of reduction. [Means for solving the problem]

[0009] One aspect of the present invention that solves the above-mentioned problems is bedding comprising a first sheet that is polygonal in shape with a pair of short sides and a pair of long sides that are approximately perpendicular to the pair of short sides, has a predetermined thickness and supports the entire body of a user, a second sheet that is positioned near one of the pair of short sides of the first sheet and has an inclined thickness, and a third sheet that is further positioned on the second sheet and has a predetermined thickness, wherein the third sheet comprises a headrest portion that extends in a direction along the short sides of the first sheet, and a backrest portion that has a plurality of protrusions that extend approximately perpendicular to the headrest portion.

[0010] In addition, in this respect, although not limited thereto, it is preferable to include a cover that covers the first sheet, the second sheet, and the third sheet.

[0011] In addition, in this respect, although not limited thereto, it is preferable that the repulsive forces of the first sheet and the third sheet are greater than the repulsive force of the second sheet.

[0012] Further, in this respect, although not limited thereto, it is preferable that the repulsive force of the convex portions of the backrest portion of the third sheet is greater in the vicinity of the long sides than in the vicinity of the center.

[0013] In addition, in this respect, although not limited thereto, it is preferable that the third sheet is made of entangled filamentous resin with gaps provided therebetween.

[0014] In addition, although not limited to this aspect, in the third sheet, it is preferable that the boundaries of each convex portion in the headrest portion and the backrest portion, and the boundaries between each convex portion, are formed by heat pressing a thick, smooth, pre-processed sheet.

[0015] In addition, in this respect, although not limited thereto, it is preferable that the width of the protrusions located near the center of the pair of long sides of the first sheet is wider than the width of the protrusions located near the long sides.

[0016] In addition, in this respect, although not limited thereto, it is preferable that the height of the protrusions near the center of the pair of long sides of the first sheet is lower than the height of the protrusions near the long sides.

[0021] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention can be embodied in many different forms, and is not limited to the specific examples shown in the following embodiments and examples.

[0022] Fig. 1 is a diagram showing an outline (without the cover) of bedding 1 according to this embodiment (hereinafter referred to as "the bedding"), and Fig. 2 is a diagram showing the bedding 1 with the cover on. A user of the bedding 1 (hereinafter simply referred to as "the user") uses the bedding shown in Fig. 2 with the cover on.

[0023] As shown in Figure 1, the bedding 1 is polygonal in shape having a pair of short sides 21 and a pair of long sides 22 in a direction approximately perpendicular to the pair of short sides 21, and is equipped with a first sheet 2 having a predetermined thickness and supporting the entire body of a user, a second sheet 3 having an inclined thickness and arranged near one of the pair of short sides 21 of the first sheet 2, and a third sheet 4 having a predetermined thickness and arranged on the second sheet 3, and the third sheet 4 is equipped with a headrest portion 41 extending in a direction along the short side 21 of the first sheet 2, and a backrest portion 42 having a plurality of protrusions 421 extending approximately perpendicular to the headrest portion 41.

[0024] As shown in FIG. 2, the bedding 1 preferably includes, but is not limited to, a cover that covers the first sheet 2, the second sheet 3 and the third sheet 4.

[0025] 3 is a diagram showing an outline of the first sheet 2 of the present bedding 1. The first sheet 2 is placed under the second sheet 3 and the third sheet 4, and is a member for supporting the upper body including the head of the user, and functions in conjunction with the second sheet 3 and the third sheet 4.

[0026] As described above, the first sheet 2 of the bedding 1 has a polygonal shape having a pair of short sides 21 and a pair of long sides 22 that are substantially perpendicular to the pair of short sides 21 .

[0027] The shape of the first sheet 2 of the present bedding 1 has two pairs of sides and is typically a quadrangle such as a rectangle, but is not limited thereto as long as it has a pair of sides.

[0028] As described above, the first sheet 2 of the present bedding 1 has a predetermined thickness and is capable of supporting the entire body of the user. This predetermined thickness is preferably a thickness and softness that allows the user's body to sink into while supporting it. The thickness can be adjusted as appropriate depending on the softness and material, but the thickness is preferably 2 cm or more and 15 cm or less, and more preferably 10 cm or less.

[0029] The material of the first sheet 2 in the present bedding 1 is not particularly limited, but is preferably soft, while having a certain degree of hardness to support the body. Specific examples of the material that can be used include, but are not limited to, cotton, polyester, etc.

[0030] The index of the softness of the first sheet 2 in the present bedding 1 is the degree to which the user feels comfortable, and is preferably expressed, for example, in "Newton (N)," a unit generally used to express the hardness and resilience of a mattress. This index applies not only to the first sheet 2, but also to the second sheet 3 and the third sheet 4.

[0031] 4 is a schematic diagram of the second sheet 3 according to this embodiment. As shown in the figure, the second sheet 3 is disposed in the vicinity of one of a pair of short sides 21 of the first sheet 2, and has a tapered thickness.

[0032] As described above, the second sheet 3 is disposed near one of the pair of short sides 21 of the first sheet 2. Generally, a user lies down along the long side, and therefore faces the head toward the short side. Therefore, by providing the second sheet 3 near one of the short sides on which the head is positioned, it is possible to raise the height of the head when the head is placed, thereby creating a comfortable state.

[0033] Furthermore, the width of the second sheet 3 (the length along the short side 21 of the first sheet 2) is not limited, but is preferably the same as the length of the short side 21 of the first sheet 2. In this way, a sense of unity as a mattress can be maintained.

[0034] Furthermore, the length of the second sheet 3 (the length along the long side 22 of the first sheet 2) is not limited, but is preferably shorter than the length of the long side 22 of the first sheet 2. This has the advantage that the height of the portion where the second sheet 3 is not arranged is low and the height of the portion where the second sheet 3 is arranged can be high, making it possible to maintain the height of the user's head high.

[0035] As described above, the thickness of the second sheet 3 has a gradient. Specifically, it is preferable that the thickness is gradually increased in the length direction. In this case, it is preferable that the thicker side is closer to the short side 21 of the first sheet 2, because this allows the user's head to be kept high, as described above.

[0036] The thickness of the second sheet 3 may be zero on the thin side when it is theoretically the apex, but it is preferable to have a thickness of about 1 cm, while the thickness on the thick side has a large adjustment range, ranging from 3 cm to 20 cm. By making it 3 cm or more, you can feel the tilt, while making it 20 cm or less makes it possible to keep the head position from being too high.

[0037] The material of the second sheet is not limited, but is preferably softer than the first sheet 2 and the third sheet described below, and a specific material that can be used is, for example, urethane, but is not limited thereto. The effect of this will be described separately later.

[0038] 5 is a schematic diagram of the third sheet 4 according to this embodiment. As shown in the figure, the third sheet 4 is further disposed on the second sheet 3 and has a predetermined thickness.

[0039] This bedding 1 has a first sheet 2, a second sheet 3 on top of it, and a third sheet 4 on top of that, which allows the user to adjust the position of the body while sleeping, reduce the strain on the body, and improve the quality of sleep and the effect of reduction. The specific effects will be clear from the following explanation.

[0040] The third sheet 4 in the present bedding 1 is preferably, but not limited to, made of filamentous resin entangled with gaps. This has the advantage that it is possible to maintain a suitable softness (hardness) and also improves breathability due to the presence of gaps. The filamentous resin is preferably, but not limited to, polyester, for example, which is injected in the form of filaments and entangled to form gaps, thereby achieving a suitable softness (hardness).

[0041] As described above, the third seat 4 has a predetermined thickness. As described above, this predetermined thickness is sufficient as long as it is thick enough to accommodate the headrest portion 41 and the backrest portion 42. That is, the thickness is preferably in the range of 0.5 cm to 5 cm, and more preferably 3 cm or less.

[0042] As described above, the third sheet 4 has a headrest portion 41 and a backrest portion 42. In the present bedding 1, by providing the headrest portion 41 and the backrest portion 42, the head and back can be comfortably supported, and by adjusting these, the quality of sleep and the effect of correction can be improved.

[0043] Furthermore, the headrest portion 41 of the third seat 4 is a portion on which the user places his / her head, and has a shape that extends in a direction along the short side 21 of the first seat 2 as described above. This shape ensures that the user's head can be placed on it even if the user turns over in their sleep and the position of their head moves in the direction of the short side of the first seat 2. Although the shape is not limited to this, a rectangular or elliptical shape is preferable. In this way, it is possible to obtain a headrest that extends in one direction.

[0044] Furthermore, the backrest portion 42 of the third sheet 4 is a portion against which the user rests his / her back, and as described above, has multiple protrusions 421 extending substantially perpendicular to the headrest portion 41 (short side 21 of the first sheet 2). In the present bedding 1, by providing multiple protrusions 421, it is possible to independently adjust the protrusions 421, specifically the height and softness of the protrusions 421, as described below. Note that Fig. 6 shows a cross section of the backrest portion 42 of the third sheet 4 cut in a direction along the short side thereof.

[0045] Furthermore, each of the protruding portions 421 of the back support portion 42 extends approximately perpendicular to the short side 21 of the first sheet 2, i.e., toward the long side 22 of the first sheet 2, but it is preferable that the multiple protruding portions 421 are arranged side by side in the direction of the short side 21 of the first sheet 2. This makes it possible to adjust the softness, height, etc. in the direction of the short side 21 of the first sheet 2.

[0046] Specifically, it is preferable that the repulsive force of the protrusions 421 of the back support portion 42 is greater in the vicinity of the long side than in the vicinity of the center. In this way, the repulsive force of the protrusions 421 in the vicinity of the center of the short side of the first sheet 2 is weakened, i.e., made soft, while the repulsive force is increased, i.e., made hard, toward the edge, making it easier for the user to turn over in their sleep toward the center of the short side. In other words, this has the effect of encouraging turning over toward the center. An image of this case is shown in FIG. 7.

[0047] Incidentally, in the third sheet 4 of the present bedding 1, it is preferable that the protrusions 421 in the headrest portion 41 and the backrest portion 42, and the boundary portions between the protrusions 421, are formed by heat pressing a smooth, thick unprocessed sheet. In this way, the third sheet 4 can be formed simply by heat pressing one sheet, which has the advantages of facilitating manufacture and enabling adjustment of the height and softness, as described below.

[0048] In addition, in the third sheet 4 of the present bedding 1, although not limited thereto, it is preferable that the width of the convex portion 421 near the center of the pair of long sides is wider than the width of the convex portion 421 near the long side 22 of the first sheet 2 in the back support portion 42. As described above, the convex portion 421 near the center is soft and the convex portion 421 near the long side is hard, which promotes turning over toward the center, but when the same material is used as described above, it is not easy to adjust the softness. However, the hardness can be adjusted by adjusting the width. In other words, a wider width makes it softer, and a narrower width makes it harder.

[0049] In addition, in the third sheet 4 of the present bedding 1, it is preferable that the height of the protrusions 421 near the center of the pair of long sides is lower than the height of the protrusions 421 near the long sides 22 of the first sheet 2. As described above, this is because it is preferable that the protrusions are lower near the center in order to encourage the user to turn over toward the center.

[0050] Furthermore, in the third sheet 4 of the present bedding 1, although this is not limited thereto, it is preferable that the back support portion 42 has at least five or more protruding portions 421. By having five or more protruding portions, it is possible to gradually adjust the softness and height toward the center, which has the advantage of reducing discomfort caused by this difference.

[0051] Furthermore, although not limited thereto, it is preferable that the height of the headrest portion 41 is higher than the height of the backrest portion 42. This is because, since the headrest portion 41 is for supporting the head and the backrest portion 42 is for supporting the back, making the portion on which the head is placed higher ensures comfort and also allows the headrest portion 41 to be made softer.

[0052] As described above, the present invention can provide bedding that improves sleep quality and the effect of rehabilitation. [Industrial Applicability]
