Description

Technical Field

[0001] The present invention relates to a mattress.

Background Art

[0002] A mattress uses a flexible material such as urethane resin to flexibly receive the body weight of a person lying down and functions as a cushioning material.

[0003] Conventionally, in a mattress, when a person lying down is lying on the mattress on their back, the back, buttocks, and heels of the person lying down protrude downward, increasing the body pressure. Therefore, it is required to more flexibly receive the body weight at positions corresponding to the back, buttocks, and heels of the person lying down in order to improve the comfort.

[0004] Conventionally, in order to further enhance the flexibility of a mattress, slits are formed on the surface of the mattress (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, if slits are provided on the surface of the mattress at positions corresponding to the back, buttocks, and heels of a person lying down (a person lying on a bed in the supine position or the lateral position, etc.), the body pressure of the person lying down will repeatedly act on the slits, and there is a risk that the mattress will break at the part where the slits are provided. Also, when washing the mattress, force will be applied to the slits, and there is a risk that the mattress will break at the part where the slits are provided.

[0007] Therefore, if only slits are provided at positions corresponding to the back, hips, and heels of a person lying down, there is a risk that the mattress will have low durability.

Means for Solving the Problem

[0008] Therefore, in the present invention according to claim 1, in the mattress, a base layer harder than the surface layer is provided on the lower surface of the surface layer. A back surface layer is provided on the lower surface of the base layer, At positions corresponding to the the hip or / and the heel of a person lying down in the surface layer, a plurality of grooves with a predetermined width extending in the width direction and not reaching the base layer are provided to a depth that does not reach the base layer. on the surface layer provided and a plurality of grooves with a predetermined width extending in the width direction and not reaching the base layer with a depth not reaching the base layer are provided in the back surface layer at a position corresponding to the knees of the lying person in the back surface layer, and a plurality of grooves with a predetermined width extending in the width direction and reaching the middle part of the base layer with a depth reaching the middle part of the base layer are alternately provided in the surface layer and the back surface layer at a position corresponding to the back of the lying person in the surface layer and the back surface layer to form a bellows shape It was decided to do so.

[0009] Further, in the present invention according to claim 2, in the present invention according to claim 1, the base layer is made harder and thinner than the surface layer and the back surface layer It was decided to do so.

[0010] Further, in the present invention according to claim 3, in the present invention according to claim 1 or claim 2, Handles are respectively provided on the front end side and the central side of the mattress cover, and the mattress cover is covered on the mattress so that the position between the handle on the front end side and the handle on the central side corresponds to the back of the lying person, and the mattress is bent between the handle on the front end side and the handle on the central side so that the handle on the front end side of the mattress cover and the handle on the central side can be overlapped and gripped It was decided to do so.

[0011] Further, in the present invention according to claim 4, in the present invention according to any one of claims 1 to 3, a mattress cover having water absorption and / or hydrophilicity is detachably provided to cover the grooves with the mattress cover.

Effect of the Invention

[0012] And in the present invention, the following effects are achieved.

[0013] That is, in the present invention, in the mattress, a base layer harder than the surface layer is provided on the lower surface of the surface layer, and a plurality of grooves with a predetermined width extending in the width direction and not reaching the base layer are provided at positions corresponding to the back or / and buttocks or / and heels of the lying person in the surface layer, so that at positions corresponding to the back, buttocks, and heels of the lying person where body pressure is likely to concentrate, the body pressure can be further dispersed, improving the comfort of lying, and since the grooves do not reach the base layer harder than the surface layer, it is possible to prevent the mattress from breaking even when repeatedly receiving the body pressure of the lying person or when repeatedly applying force during washing.

[0014] In particular, a back surface layer harder than the surface layer is provided on the lower surface of the base layer, and a plurality of grooves with a predetermined width extending in the width direction and not reaching the base layer are provided at positions corresponding to the knees of the lying person in the back surface layer, so that even when lying on the back surface layer side, the flexibility at the knees can be maintained without impairing the comfort due to the hardness of the back surface layer.

[0015] Also, a back surface layer harder than the surface layer is provided on the lower surface of the base layer, and a plurality of grooves with a predetermined width extending in the width direction and reaching the middle part of the base layer are alternately provided at positions corresponding to the back of the lying person in the surface layer and the back surface layer, forming a bellows shape, so that the flexibility of the mattress at the back can be improved and the body pressure on the back of the lying person can be reduced.

[0016] Also, a mattress cover having water absorption or / and hydrophilicity is detachably provided, and since the grooves are covered by the mattress cover, a space is formed under the mattress cover by the grooves, and moisture such as sweat can be dried more quickly.

Mode for Carrying Out the Invention

[0018] Hereinafter, the specific configuration of the mattress according to the present invention will be described with reference to the drawings.

[0019] As shown in FIG. 1, the mattress 1 has a vertically long rectangular plate shape having elasticity such as urethane resin, and the whole is detachably covered with a mattress cover 2.

[0020] As shown in FIGS. 1 and 2, the mattress 1 has a surface layer 4 having the same shape attached to the upper surface of a vertically long rectangular plate-shaped base layer 3, and a back surface layer 5 having the same shape attached to the lower surface of the base layer 3.

[0021] Here, in the mattress 1, the base layer 3 is the hardest and thinnest, the back surface layer 5 is harder and thinner than the surface layer 4, and it can also be used with the front and back reversed. When a softer sleeping comfort is preferred, it is used with the surface layer 4 side facing upward, and when a harder sleeping comfort is preferred, it is used with the back surface layer 5 side facing upward.

[0022] As shown in FIGS. 2 and 3, this mattress 1 has a plurality of grooves 7 extending in the width direction from the left end to the right end at a position corresponding to the back (including the shoulders) of the person lying horizontally 6 (a person lying on the bed in the supine position or the lateral lying position, etc.) in the surface layer 4.

[0023] These grooves 7 have a constant width w1 in the front-rear direction, are formed at a depth d1 reaching from the upper end surface of the surface layer 4 to the middle part of the base layer 3, and are formed in parallel in the front-rear direction at a constant interval t1 (FIG. 3(a)).

[0024] As a result, the mattress 1 is formed with a bent portion 8 that can be easily bent toward the surface layer 4 at a position corresponding to the back of the lying person 6 (the front end side of the mattress 1). This bent portion 8 also functions as a body pressure reducing portion that can reduce the body pressure on the back of the lying person 6 in the surface layer 4.

[0025] Further, the mattress 1 is formed with a plurality of grooves 9 that extend across the width direction from the left end to the right end at a position corresponding to the back of the lying person 6 in the back surface layer 5.

[0026] These grooves 9 have a constant width w2 in the front - rear direction, are formed to a depth d2 that reaches from the lower end surface of the back surface layer 5 to the middle part of the base layer 3, and are formed parallel to each other in the front - rear direction at a constant interval t2 (Fig. 3(a)). Here, the interval t1 of the grooves 7 formed in the surface layer 4 and the interval t2 of the grooves 9 formed in the back surface layer 5 are made the same, and the grooves 9 on the back surface layer 5 side are positioned between the adjacent grooves 7, 7 on the surface layer 4 side, and the grooves 7 on the surface layer 4 side and the grooves 9 on the back surface layer 5 side are provided alternately so as to be accordion - shaped as a whole.

[0027] As a result, the mattress 1 is formed with a bent portion 10 that can be easily bent toward the back surface layer 5 at a position corresponding to the back of the lying person 6 (the front end side of the mattress 1). This bent portion 10 also functions as a body pressure reducing portion that can reduce the body pressure on the back of the lying person 6 in the back surface layer 5.

[0028] Further, the mattress 1 is formed with a plurality of grooves 11 that extend across the width direction from the left end to the right end at a position corresponding to the buttocks of the lying person 6 in the surface layer 4.

[0029] These grooves 11 have a constant width w3 in the front - rear direction, are formed to a depth d3 that reaches from the upper end surface of the surface layer 4 to the middle part of the surface layer 4 but does not reach the base layer 3, and are formed parallel to each other in the front - rear direction at a constant interval t3 (Fig. 3(b)).

[0030] As a result, on the mattress 1, a body pressure reducing portion 12 capable of reducing the body pressure of the buttocks of the lying person 6 is formed at a position corresponding to the buttocks of the lying person 6 in the surface layer 4.

[0031] Further, the mattress 1 forms a plurality of grooves 13 extending across the width direction from the left end to the right end at a position corresponding to the heels of the lying person 6 in the surface layer 4.

[0032] These grooves 13 have a constant width w4 in the front - rear direction, are formed at a depth d4 that does not reach the base layer 3 from the upper end surface of the surface layer 4 to the middle part of the surface layer 4, and are formed in parallel in the front - rear direction at a constant interval t4 (Fig. 3(d)).

[0033] As a result, on the mattress 1, a body pressure reducing portion 14 capable of reducing the body pressure of the heels of the lying person 6 is formed at a position corresponding to the heels of the lying person 6 in the surface layer 4.

[0034] Furthermore, the mattress 1 forms a plurality of grooves 15 extending across the width direction from the left end to the right end at a position corresponding to the knees of the lying person 6 in the back surface layer 5 (the back side of the position corresponding to the middle between the buttocks and the heels of the lying person 6 in the surface layer 4). Although forming a plurality of grooves 15 in the back surface layer 5 which is harder than the surface layer 4 would reduce the hardness, by forming the grooves 15 on the back of the knees of the lying person 6 where the contact with the mattress 1 (back surface layer 5) is reduced when lying on the back surface layer 5 side, it becomes less likely to feel the reduction in the hardness of the back surface layer 5 due to the formation of the grooves 15, and the comfort of lying on the back surface layer 5 is not impaired.

[0035] These grooves 15 have a constant width w5 in the front - rear direction, are formed at a depth d5 that does not reach the base layer 3 from the lower end surface of the back surface layer 5 to the middle part of the back surface layer 5, and are formed in parallel in the front - rear direction at a constant interval t5 (Fig. 3(c)).

[0036] As a result, the mattress 1 is formed with a bent portion 16 that can be easily bent toward the back surface layer 5 at a position corresponding to the knees of the recumbent person 6 in the back surface layer 5. This bent portion 16 also functions as a body pressure reducing portion that can reduce the body pressure on the knees of the recumbent person 6 in the back surface layer 5.

[0037] As shown in FIG. 4, when the mattress 1 having the above configuration is used on a reclining bed 17, the body pressure reducing portion 12 is positioned above the hip support 18 fixed to the bed 17, and the bent portions 8 and 10 are positioned above the bent portions of the back support 19 and the shoulder support 20 that tilt with respect to the hip support 18. The bent portion 16 is positioned above the bent portion between the thigh support 21 and the lower leg support 22 that tilt with respect to the hip support 18, and the body pressure reducing portion 14 is positioned above the lower leg support 22. By positioning the bent portions 8, 10, and 16 of the mattress 1 above the bent portions between the back support 19 and the shoulder support 20 of the bed 17 and between the thigh support 21 and the lower leg support 22, the followability of the mattress 1 is improved when the bed 1 is reclined, preventing the body of the recumbent person 6 from slipping off and being loaded.

[0038] In the above mattress 1, a plurality of grooves 11 and 13 having a predetermined width extending in the width direction and not reaching the base layer 3 are formed at positions corresponding to the hips and heels of the recumbent person 6 in the surface layer 4. However, the present invention is not limited to this, and the grooves may be formed at positions corresponding to the back or / and hips or / and heels of the recumbent person 6 in the surface layer 4.

[0039] As shown in FIG. 1, the mattress cover 2 covering the above mattress 1 is provided with a pair of handles 23 and 24 for use during transportation.

[0040] Here, the handles 23 and 24 are provided asymmetrically on the front end side and the center side of one long side of the rectangular vertically long mattress cover 2.

[0041] Then, as shown in FIG. 5, the mattress cover 2 can overlap the front handle 23 and the central handle 24 of the mattress cover 2 by bending the mattress 1 between the front handle 23 and the central handle 24 on the front end side, so that both handles 23 and 24 can be gripped with one hand.

[0042] As a result, in the state where the front handle 23 and the central handle 24 of the mattress cover 2 are overlapped, the mattress 1 is overlapped only on the front side of both handles 23 and 24, and the mattress 1 is not overlapped on the rear side of both handles 23 and 24. The mattress 1 can be carried in a posture where the carrier stands on the rear side of both handles 23 and 24 and grips both handles 23 and 24 on the front side of the carrier.

[0043] In particular, in the above-mentioned mattress 1, since the bent portion 8 of the surface layer 4 and the bent portion 10 of the back surface layer 5 are formed at positions corresponding to between the front handle 23 and the central handle 24 of the mattress cover 2, the mattress 1 can be easily bent between the front handle 23 and the central handle 24, and the mattress 1 can be easily bent to either the surface layer 4 side (FIG. 5(a)) or the back surface layer 5 side (FIGS. 5(b) and (c)) of the mattress 1.

[0044] For this mattress cover 2, a material having water absorption or hydrophilicity can be used. Even if moisture such as beverages or sweat drips onto the mattress cover 2, the water absorption of the mattress cover 2 absorbs the moisture, and the hydrophilicity of the mattress cover 2 diffuses the moisture, so that the surface of the mattress cover 2 can be quickly dried and stuffiness can be prevented. In addition, for the mattress cover 2, by using a polyester fabric instead of the conventional nylon fabric for the base fabric material, it becomes possible to mix a flame retardant agent (fireproofing agent) into the polyurethane and apply it to the base fabric, and then perform a hydrophilic treatment, so that a hydrophilic treatment with flame retardant performance can be achieved.

[0045] In particular, in the above-mentioned mattress 1, since the grooves 7, 9, 11, 13 are formed at positions corresponding to the back, buttocks, and heels where the body pressure of the person lying on the side 6 is greater than others, spaces with a predetermined width w1, w2, w3, w4 and a predetermined depth d1, d2, d3, d4 are formed on the back side of the mattress cover 2 in a state where the grooves 7, 9, 11, 13 are covered by the mattress cover 2, and sweat and the like can be dried more quickly.

[0046] As described above, the above-mentioned mattress 1 has a base layer 3 harder than the surface layer 4 attached to the lower surface of the surface layer 4, and a plurality of grooves 11, 13 with a predetermined width w3, w4 extending in the width direction and a depth d3, d4 that does not reach the base layer 3 are provided at positions corresponding to the back or / and buttocks or / and heels of the person lying on the side 6 in the surface layer 4.

[0047] Therefore, in the mattress 1 with the above-mentioned configuration, the body load can be received more flexibly at positions corresponding to the buttocks and heels of the person lying on the side 6, improving the comfort of lying down. At the same time, since the grooves 11, 13 do not reach the base layer 3 harder than the surface layer 4, it is possible to prevent the mattress 1 from breaking even when repeatedly receiving the body pressure of the person lying on the side 6 or when repeatedly applying force during washing.

[0048] In addition, the above-mentioned mattress 1 has a back surface layer 5 harder than the surface layer 4 attached to the lower surface of the base layer 3, and can be used with the front and back reversed. A plurality of grooves 15 with a predetermined width w5 extending in the width direction and a depth d5 that does not reach the base layer 3 are provided at positions corresponding to the knees of the person lying on the side 6 in the back surface layer 5.

[0049] Therefore, in the mattress 1 with the above-mentioned configuration, even when lying on the back surface layer 5 side with the front and back reversed, the flexibility at the knees can be maintained without impairing the comfort due to the hardness of the back surface layer 5.

[0050] Further, the above-mentioned mattress 1 is provided with a detachable mattress cover 2 having water absorption and / or hydrophilicity, and since the grooves 11, 13, and 15 are covered with the mattress cover 2, spaces are formed by the grooves 11, 13, and 15 on the lower side of the mattress cover 2, and moisture such as sweat can be dried more quickly.

[0051] Further, the above-mentioned mattress 1 has the entire rectangular vertically long mattress 1 covered with a mattress cover 2, and handles 23 and 24 are respectively provided on the front end side and the central side of the long side of the mattress cover 2, and the mattress 1 is bent between the handle 23 on the front end side and the handle 24 on the central side so that the handle 23 on the front end side of the mattress cover 2 and the handle 24 on the central side can be gripped with one hand.

[0052] Therefore, in the mattress 1 having the above configuration, the mattress 1 is in a state of overlapping only on the front side of both handles 23 and 24, and the mattress 1 does not overlap on the rear side of both handles 23 and 24. A carrier can stand on the rear side of both handles 23 and 24 and carry the mattress 1 in a posture of gripping both handles 23 and 24 on the front side of the carrier. Therefore, the lateral width occupied during transportation becomes smaller, and the mattress 1 can be carried even in a narrow space as long as there is a width equal to the thickness of the carrier's body and one mattress 1, and the workability and safety during transportation can be improved.

[0053] Further, the above-mentioned mattress 1 has a configuration in which bending portions 8 and 10 that can be easily bent are formed at positions between the handle 23 on the front end side and the handle 24 on the central side in the mattress 1.

[0054] Therefore, in the mattress 1 having the above configuration, the mattress 1 can be easily bent at the bending portions 8 and 10 during transportation so that the handle 23 on the front end side and the handle 24 on the central side of the mattress cover 2 can be gripped with one hand.

[0055] Further, the above-mentioned mattress 1 is provided with grooves 7 and 9 extending in the width direction alternately on the front surface and the back surface of the mattress 1 to form the bending portions 8 and 10, and the mattress 1 can be bent to either the front or the back side at the bending portions 8 and 10.

[0056] Therefore, with the mattress 1 configured as described above, it becomes possible to carry the mattress 1 while changing its bent posture according to the dominant arm of the carrier, the state of the passage for carrying, and the like.
