Description

[Technical field]

[0001] This invention relates to foam mattresses. [Background technology]

[0002] Patent Document 1 provides a novel mattress that makes it easy to turn over in sleep. The mattress includes a support surface that contacts the user's body, a plurality of first grooves that extend along the short side direction of the support surface and have a first depth from the support surface, a plurality of second grooves that extend along the long side direction of the support surface and have a second depth from the support surface that is greater than the first depth, and a plurality of protruding portions separated by two adjacent first grooves and two adjacent second grooves. The protruding portions have a top surface, and at least a portion of the top surface includes the support surface.

[0003] Patent Document 2 provides a mattress with improved turning over ability. The mattress 1 includes at least three layers of cushioning material, a first layer 11, a second layer 12, and a third layer 13, each having a predetermined thickness. In the thickness direction, the second layer 12 is sandwiched between the first layer 11 and the third layer 13 and stacked. The second layer 12 has a lower resilience modulus than the first layer 11 and the third layer 13. The thickness t3 of the third layer 13 is equal to or greater than the sum of the thickness t1 of the first layer 11 and the thickness t2 of the second layer 12. The first layer 11 and the second layer 12 are formed with grooves 5 that penetrate the first layer 11 in the thickness direction and continue to at least a part of the second layer 12. The grooves 5 are formed by continuous or / and discontinuous straight lines or / and curves in a plan view from the surface of the first layer 11.

[0004] Patent Document 3 provides a mattress for a bed with a raised bed section that has good breathability, improves the diffusion and heat dissipation of moisture and heat, has a high body pressure dispersion effect, and is useful for improving the ability to turn over in bed. This mattress has a plurality of grooves 14 formed on the upper surface 12 of a base made of a resin foam, and a plurality of grooves 17 formed on the lower surface 13 of the base, and the grooves formed on the upper surface (upper surface grooves) and the grooves formed on the lower surface (lower surface grooves) are arranged in an intersecting direction, and the total depth of the upper surface grooves and the lower surface grooves is greater than the thickness of the base, so that at the positions where the lower surface grooves and the upper surface grooves intersect, there are through holes 20 formed by communicating each other, and the upper surface grooves are arranged in the width direction.

[0005] Patent Document 4 describes a mattress characterized by using a filling in which multiple grooves are formed vertically on the front and back of a nonwoven cushioning material, with the back grooves either being the same number as on the front at a position opposite the front, or two or more on each side spaced so that the position opposite the front is approximately halfway between the front and back, and each groove is formed 1 / 8 to 1 / 3 of the way from both ends in the horizontal direction.

[0007] However, the devices disclosed in Patent Documents 1 to 4 have difficulty in encouraging the rotation of the body when turning to a lateral position, and in assisting the rotation of the body by providing a rebound force toward the center when returning to a supine position.

[0008] Therefore, the object of the present invention is to provide a foamed resin mattress that assists the body's rotation in accordance with the movement of turning over in bed. [Means for solving the problem]

[0009] The present invention has been made to solve the above-mentioned problems, and is a foamed resin mattress comprising a mattress body and a plurality of longitudinal slits arranged longitudinally at specific intervals in the short direction downward from the top surface of the mattress body, and the longitudinal slits are L-shaped when viewed from the side.

[0010] According to the mattress, the longitudinal and transverse slits improve breathability, adjust the sinking of the back and buttocks, encourage the rotation of the body when turning to the side, and assist the rotation of the body by the rebound toward the center when returning to the supine position. Such three-dimensional movement of the mattress makes it easier to turn.

[0011] It is preferable that the depth of the longitudinal slits is different, so that the sinking of the back and buttocks can be adjusted, and the ease of turning over in sleep can be further improved.

[0012] It is preferable that the depth of the longitudinal slits is deeper in the center than in the left and right ends, which can promote the initial movement of turning over and assist the patient in turning over to the lateral position.

[0013] It is preferred that the specific intervals of the longitudinal slits in the lateral direction are different, which can facilitate the movement from the lateral position back to the center and assist the rotation back to the supine position.

[0014] It is preferable that the V-shape is set to open from the center toward the left and right ends in the short direction, so that the crushed foamed resin rebounds toward the upper center, and assists in the movement of raising the body from a lateral position to a supine position.

[0015] It is preferable that the plate has a plurality of short-side slits which intersect the longitudinal slits at right angles and are provided in the short-side direction at specific intervals in the longitudinal direction from the upper surface downward.

[0016] It is preferable that the depth of the lateral slits is different, so that the compression density of the foamed resin is adjusted to suit the shoulders, which have a large contact area, and the buttocks, which have a large weight, while maintaining breathability, and thus the posture can be appropriately maintained.

[0017] It is preferable that the specific intervals of the short-side slits in the long-side direction are different, which improves the breathability of the parts that come into contact with the shoulders and buttocks, which tend to retain heat, and adjusts the compression density of the foamed resin, thereby enabling the user to maintain a suitable posture.

[0019] A mattress 1 according to an embodiment of the present invention will be described with reference to FIGS.

[0020] The mattress 1 is made of foamed resin, for example, urethane foam. As shown in Fig. 1, the mattress body 2 is divided into three members, a first member 2a, a second member 2b, and a third member 2c, and when in use, the three members can be connected and folded into three by being housed inside a cover 100 as a filling material, as shown in Fig. 8. It is also possible to have an integral structure without dividing the mattress body 2, or to connect the ends of the mattress made of the first member 2a, the second member 2b, and the third member 2c.

[0021] The size of the mattress 1 is, for example, 90 to 100 cm in width, 195 to 210 cm in length, and 5 to 20 cm in thickness, but is not limited thereto.

[0022] In the case of the urethane foam, urethane foam (high hardness urethane, high resilience urethane, film-free urethane) is preferable. The hardness of the urethane foam is preferably 140 Newtons to 300 Newtons. The density of the urethane foam is preferably 20D to 50D. The resilience of the urethane foam is preferably 40% to 55%.

[0023] The mattress body 2 is provided at a specific interval W 3a , W 3b , W 3c , W 3d A plurality of (here, ten) longitudinal slits 3a, 3b, 3c, 3d, 3e, etc. are provided in the longitudinal direction X, and a specific interval W 4a , W 4b , W 4c , W 4d , W 4e , W 4f , W 4g , W 4h、 W 4i , W 4j . . (here, 11 in each of the members 2a to 2c, a total of 33) lateral slits 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k... are provided.

[0024] The longitudinal slits 3a to 3e are characterized by being bent in a dogleg shape in side view. The dogleg shape is oriented so as to open from the center in the Y direction toward the left and right ends. The height of the dogleg is set so as to decrease from the center toward the left and right ends.

[0025] Here, the longitudinal slits 3a to 3e are spaced apart from the left and right ends toward the center at specific intervals W 3a ~W 3d In the region on one side divided by the central vertical line C, the corresponding depths D of the longitudinal slits 3a to 3e are set to be narrow. 3a , D 3b , D 3c , D 3d , D 3e In addition, the depth D in the Z direction of the longitudinal slits 3a to 3e is different. 3a ~D 3e The depth of the slits 3a to 3e is set to increase from the end portion toward the central vertical line C.

[0026] A specific interval W in the short direction Y of the longitudinal slits 3a to 3e 3a , W 3b , W 3c , W 3d are set differently.

[0027] Depth D of slits 4a to 4k in the short direction 4a , D 4b , D 4c , D 4d , D 4e , D 4f , D 4g , D 4h , D 4i , D 4j , D 4k is set differently. Depth D 4a ~D 4k The deepest parts of the slits 4a to 4k are provided at a plurality of locations (two locations in this example). 4a , W 4b , W 4c , W4d , W 4e , W 4f , W 4g , W 4h , W 4i , W 4j is set to be different. Here, the specific interval W 4a ~W 4j As viewed in FIG. 6, the width is set to increase from the left and right ends toward the center. EXAMPLES

[0028] The polyurethane foam manufactured by Sun Living Co., Ltd. was used. The hardness of the polyurethane foam is 140 Newtons to 300 Newtons. The density of the polyurethane foam is 20D to 50D. The resilience of the polyurethane foam is 40% to 55%. The dimensions of the mattress 1 are 650x3mm length, 970mm width, and 100mm thickness. The width of the longitudinal slits 3a, 3b, 3c, 3d, and 3e is 10mm, and the specific interval W 3a is 75mm, W 3b is 60mm, W 3c is 50mm, W 3d is 40mm, depth D 3a 55mm, D 3b 60mm, D 3c 65mm, D 3d and D. 3e is 70 mm, the width of the short-side slits 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, and 4k is 10 mm, and the specific interval W 4a and W 4j is 25mm, W 4b and W 4i is 30mm, W 4c and W 4h 45mm, W 4d and W 4g is 50mm, W 4e and W 4f is 70mm, depth D 4a and D 4k 55mm, D 4b , D 4f , D 4j 60mm, D 4c , D 4e , D 4g , D 4i 65mm, D4d and D 4h is 70mm.

[0029] The first member 2a to the third member 2c of the mattress 1 are stored in a cover 100 and are connected to each other. When the mattress 1 is not in use, it can be folded compactly into three as shown in Figures 2 and 8, so that it can quickly free up space even in small spaces and can be stored easily. In addition, the mattress 1 can be used in an upright or folded state to prevent moisture.

[0030] According to the mattress 1 of this embodiment, the longitudinal slits 3a-3e and the lateral slits 4a-4k increase breathability, adjust the sinking of the back and buttocks, encourage the rotation of the body when turning to the side, and assist the rotation of the body when returning to the supine position by the repulsion toward the center. Such three-dimensional movement of the mattress 1 can increase the ease of turning.

[0031] Depth D of the longitudinal slits 3a to 3e 3a ~D 3e Since the cushion has different cushioning, it is possible to adjust the amount of sinking of the back and buttocks, making it even easier to turn over in bed.

[0032] Depth D of the longitudinal slits 3a to 3e 3a ~D 3e Since the slit in the center is deeper than the slits at the left and right ends, it encourages the initial movement of turning over and assists in turning over to the lateral position.

[0033] A specific interval W in the short direction Y of the longitudinal slits 3a to 3e 3a ~W 3d Since the difference in the position between the lateral and central positions can be achieved, the rotation from the lateral position back to the central position can be promoted and the rotation back to the supine position can be assisted.

[0034] The L-shape of the longitudinal slits 3a to 3e is oriented so as to open toward the left and right ends, so that the crushed foamed resin rebounds toward the upper center, assisting in the movement of raising the body from a lateral position to a supine position.

[0035] Depth D of slits 4a to 4k in the short direction 4a ~D 4k Since the compression density of the foamed resin is different, the compression density is adjusted to suit the shoulders, which have a large contact area, and the buttocks, which carry a large weight, while maintaining breathability, allowing the wearer to maintain an appropriate posture.

[0036] A specific interval W in the short-side direction Y of the short-side slits 4a to 4k 4a ~W 4j Since the material is different, it is possible to improve breathability in areas that come into contact with the shoulders and buttocks, where heat tends to build up, and adjust the compression density of the foamed resin, allowing the wearer to maintain a suitable posture. [Industrial Applicability]

[0037] The present invention provides a mattress with excellent breathability and ease of turning over, and is of great industrial value. [Explanation of symbols]
