Description

[Technical Field]

[0001] The present invention relates to a mattress that is entirely covered with a mattress cover. [Background technology]

[0002] Mattresses used at home, in hospitals, nursing homes, etc. are provided with handles on the mattress cover that covers the entire mattress so that they can be easily carried when transported for cleaning, installation, etc.

[0003] Conventional mattresses have handles symmetrically provided on the front and back of the long sides of the mattress cover, and the carrier would carry the mattress by holding the front and back handles with both hands (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-276083 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with conventional mattresses, the mattress carrier must carry the mattress while grasping the handles provided at symmetrical positions on the front and back of the long sides of the mattress cover with both hands, which requires the carrier to carry the mattress in an awkward position.

[0006] As a result, conventional mattresses are difficult to transport and install at home, in hospitals, nursing homes, etc., and are also unsafe as there is a risk that the mattress may collide with equipment, furniture, or passing people. [Means for solving the problem]

[0007] Therefore, in the present invention according to claim 1, the entire rectangular, elongated mattress is covered with a mattress cover, and handles are provided on the front and center sides of the long sides of the mattress cover, so that the mattress can be bent between the handles on the front and center sides and the handles on the front and center sides of the mattress cover can be held with one hand, and only in the position between the handles on the front and center sides, there are handles on the front and back sides. With grooves extending to the left and right A bending portion is formed so that the mattress can be bent to either the front or back side at a position between the handle on the front end side and the handle on the central side.

[0008] In addition, in the present invention according to claim 2, in the present invention according to claim 1, the mattress is a mattress used in a reclining bed, and the position between the handle on the front end side and the handle on the center side corresponds to the back of a person lying down, and only at that position are there any adhesives on the front and back sides. With grooves extending to the left and right The curved portion is formed at the position corresponding to the buttocks and heels of the lying person, and the surface is With grooves extending to the left and right We decided to form a bent section.

[0009] In addition, in the present invention according to claim 3, in the present invention according to claim 2, The mattress has a surface layer and a back layer on the upper and lower surfaces of the hardest base layer, and grooves extending in the width direction to a depth that reaches the base layer are alternately provided in the surface layer and back layer at a position corresponding to the back of the recumbent, forming a curved portion, and grooves extending in the width direction to a depth that does not reach the base layer are provided only in the surface layer at a position corresponding to the buttocks and heels of the recumbent, forming a curved portion. I decided to do it. [Effects of the Invention]

[0010] The present invention provides the following effects.

[0011] In other words, in the present invention, the entire rectangular, elongated mattress is covered with a mattress cover, and handles are provided on the front and central sides of the long sides of the mattress cover, and the mattress is bent between the front handle and the central handle so that the handle on the front end of the mattress cover and the handle on the central side can be held with one hand.As a result, the mattresses are overlapped only on the front side of the central handle, and are not overlapped behind the central handle, and the carrier can carry the mattress in a position where they stand behind the central handle and hold both handles in front of them, which reduces the width occupied during transportation and improves workability and safety during transportation.

[0012] In particular, if an easily bendable bending portion is formed at a position between the front end handle and the central handle of the mattress, the mattress can be easily bent at the bending portion during transport, allowing the front end handle and the central handle of the mattress cover to be held with one hand.

[0013] Furthermore, if grooves extending in the width direction are alternately provided on the front and back surfaces of the mattress to form the bending portion, and the mattress can be bent to either the front or back at the bending portion, the mattress can be transported with its bent position changed depending on the carrier's dominant hand and the condition of the passageway along which it is being transported.

[Figure 2] Top view (a), side view (b), and bottom view (c) of the mattress. [Figure 3] FIG. [Figure 4] FIG. [Figure 5] FIG. 2 is an explanatory diagram showing the shape of the mattress when transported. DETAILED DESCRIPTION OF THE INVENTION

[0015] The specific configuration of the mattress according to the present invention will be described below with reference to the drawings.

[0016] As shown in FIG. 1, a mattress 1 is in the shape of a vertically long rectangular plate made of elastic urethane resin or the like, and is entirely covered with a mattress cover 2 in a removable manner.

[0017] As shown in FIGS. 1 and 2, the mattress 1 has a base layer 3 in the shape of a vertically long rectangular plate, a surface layer 4 of the same shape attached to the upper surface of the base layer 3, and a back layer 5 of the same shape attached to the lower surface of the base layer 3.

[0018] Here, the mattress 1 has a base layer 3 that is the hardest and thinnest, and a back layer 5 that is harder and thinner than the surface layer 4, and can be used upside down; if a softer sleeping comfort is preferred, the mattress is used with the surface layer 4 side facing up, and if a harder sleeping comfort is preferred, the mattress is used with the back layer 5 side facing up.

[0019] As shown in Figures 2 and 3, this mattress 1 has multiple grooves 7 formed in the surface layer 4 at a position corresponding to the back (including the shoulders) of a reclining person 6 (a person lying on the bed in a supine or lateral position, etc.), extending across the entire width from the left end to the right end.

[0020] The grooves 7 have a constant width w1 in the front-to-back direction, and are formed to a depth d1 that reaches from the upper end surface of the surface layer 4 to the middle of the base layer 3, and are arranged parallel to each other at a constant interval t1 in the front-to-back direction (Figure 3(a)).

[0021] As a result, the mattress 1 has a bent portion 8 formed at a position (front end side of the mattress 1) corresponding to the back of the recumbent 6, which can be easily bent toward the surface layer 4. This bent portion 8 also functions as a body pressure reducing portion in the surface layer 4 that can reduce the body pressure on the back of the recumbent 6.

[0022] The mattress 1 also has a plurality of grooves 9 formed in the back layer 5 at positions corresponding to the back of the recumbent 6, the grooves 9 extending across the entire width from the left end to the right end.

[0023] The grooves 9 have a constant width w2 in the front-to-rear direction, are formed to a depth d2 that reaches from the lower end surface of the back layer 5 to the middle of the base layer 3, and are arranged in parallel in the front-to-rear direction at a constant interval t2 (Fig. 3(a)). Here, the interval t1 between the grooves 7 formed in the surface layer 4 and the interval t2 between the grooves 9 formed in the back layer 5 are made the same, and the grooves 7 on the surface layer 4 side and the grooves 9 on the back layer 5 side are alternately arranged so that the grooves 9 on the back layer 5 side are located between adjacent grooves 7, 7 on the surface layer 4 side, resulting in an accordion-like shape as a whole.

[0024] As a result, the mattress 1 has a bent portion 10 formed at a position (front end side of the mattress 1) corresponding to the back of the recumbent 6, which can be easily bent toward the back surface layer 5. This bent portion 10 also functions as a body pressure reducing portion in the back surface layer 5 that can reduce the body pressure on the back of the recumbent 6.

[0025] The mattress 1 also has a plurality of grooves 11 formed in the surface layer 4 at positions corresponding to the buttocks of the recumbent 6, extending across the entire width from the left end to the right end.

[0026] The grooves 11 have a constant width w3 in the front-to-rear direction, and are formed at a depth d3 from the top surface of the surface layer 4 to the middle of the surface layer 4, not reaching the base layer 3, and are arranged parallel to each other at a constant interval t3 in the front-to-rear direction (Figure 3(b)).

[0027] As a result, the mattress 1 has a body pressure reducing portion 12 formed in the surface layer 4 at a position corresponding to the buttocks of the recumbent person 6, which can reduce the body pressure on the buttocks of the recumbent person 6.

[0028] The mattress 1 also has a plurality of grooves 13 formed in the surface layer 4 at positions corresponding to the heels of the recumbent 6, the grooves 13 extending across the entire width from the left end to the right end.

[0029] The grooves 13 have a constant width w4 in the front-to-rear direction, and are formed at a depth d4 from the top surface of the surface layer 4 to the middle of the surface layer 4, not reaching the base layer 3, and are arranged parallel to each other at a constant interval t4 in the front-to-rear direction (Figure 3(d)).

[0030] As a result, the mattress 1 has a body pressure reducing portion 14 formed in the surface layer 4 at a position corresponding to the heel of the recumbent person 6, which can reduce the body pressure at the heel of the recumbent person 6.

[0031] Furthermore, the mattress 1 has a plurality of grooves 15 formed in the back surface layer 5 at a position corresponding to the knees of the reclining person 6 (on the back side of the surface layer 4 at a position corresponding to the area between the buttocks and heels of the reclining person 6), extending across the entire width from the left end to the right end. Forming a plurality of grooves 15 in the back surface layer 5, which is harder than the surface layer 4, reduces the firmness of the mattress. However, by forming the grooves 15 behind the knees of the reclining person 6, who has less contact with the mattress 1 (back surface layer 5) when lying on the back surface layer 5 side, the reduction in the firmness of the back surface layer 5 due to the formation of the grooves 15 is less noticeable, and the comfort of sleeping on the back surface layer 5 is not impaired.

[0032] The grooves 15 have a constant width w5 in the front-to-back direction, and are formed at a depth d5 ​​from the lower end surface of the back surface layer 5 to the middle of the back surface layer 5, not reaching the base layer 3, and are arranged parallel to each other at a constant interval t5 in the front-to-back direction (Figure 3(c)).

[0033] As a result, the mattress 1 has a bent portion 16 formed in the back surface layer 5 at a position corresponding to the knees of the recumbent 6, which can be easily bent toward the back surface layer 5. The bent portion 16 also functions as a body pressure reducing portion in the back surface layer 5 that can reduce body pressure on the knees of the recumbent 6.

[0034] As shown in Figure 4, when the mattress 1 having the above configuration is used on a reclining bed 17, the body pressure reduction section 12 is located above the buttocks support 18 fixed to the bed 17, the bent sections 8 and 10 are located above the bent section between the back support 19 and shoulder support 20 which rise and fall relative to the buttocks support 18, the bent section 16 is located above the bent section between the thigh support 21 and the lower leg support 22 which rise and fall relative to the buttocks support 18, and the body pressure reduction section 14 is located above the lower leg support 22. By positioning the curved portions 8, 10, 16 of the mattress 1 above the curved portion between the back support 19 and shoulder support 20 of the bed 17 and above the curved portion between the thigh support 21 and lower leg support 22, the ability of the mattress 1 to follow the bed 1 is improved when the bed 1 is reclined, and the body of the recumbent 6 is prevented from slipping down and being subjected to stress.

[0035] In the above mattress 1, multiple grooves 11, 13 are formed in the surface layer 4 at positions corresponding to the buttocks and heels of the recumbent 6, extending widthwise, with a predetermined width and a depth that does not reach the base layer 3; however, this is not limited to this, and the grooves may also be formed in positions corresponding to the back and / or buttocks and / or heels of the recumbent 6 in the surface layer 4.

[0036] As shown in FIG. 1, the mattress cover 2 that covers the mattress 1 is provided with a pair of handles 23, 24 that are used when carrying the mattress.

[0037] Here, handles 23, 24 are provided asymmetrically at the front end and center of one long side of a rectangular, vertically elongated mattress cover 2.

[0038] As shown in Figure 5, by bending the mattress 1 between the handle 23 on the front end side and the handle 24 on the central side, the handle 23 on the front end side and the handle 24 on the central side of the mattress cover 2 can be overlapped, and both handles 23, 24 can be held with one hand.

[0039] As a result, when the handle 23 on the front end side of the mattress cover 2 and the handle 24 on the central side are overlapped, the mattress 1 is overlapped only on the front side of both handles 23, 24, and the mattress 1 is not overlapped on the rear side of both handles 23, 24, so that the carrier can carry the mattress 1 in a position where they stand on the rear side of both handles 23, 24 and hold both handles 23, 24 in front of them.

[0040] In particular, in the above mattress 1, the bent portion 8 of the surface layer 4 and the bent portion 10 of the back layer 5 are formed at a position corresponding to the area between the handle 23 on the front end side and the handle 24 on the central side of the mattress cover 2, so that the mattress 1 can be easily bent between the handle 23 on the front end side and the handle 24 on the central side, and the mattress 1 can be easily bent either toward the surface layer 4 side (Figure 5(a)) or toward the back layer 5 side (Figures 5(b), (c)).

[0041] The mattress cover 2 can be made of a material that is water-absorbent and hydrophilic. Even if moisture such as drinks or sweat drips onto the mattress cover 2, the water is absorbed by the water-absorbent properties of the mattress cover 2, and the hydrophilic properties of the mattress cover 2 diffuse the moisture, allowing the surface of the mattress cover 2 to dry quickly and prevent stuffiness. Furthermore, by using polyester as the base fabric material for the mattress cover 2 instead of the conventional nylon, it is possible to mix a flame-retardant (fire-resistant) agent with polyurethane and apply it to the base fabric before performing a hydrophilic finish, thereby achieving a hydrophilic finish with flame-retardant properties.

[0042] In particular, in the mattress 1, grooves 7, 9, 11, and 13 are formed in positions corresponding to the back, buttocks, and heels of the person 6 lying down, where the body pressure is greater than in other areas. Therefore, when the grooves 7, 9, 11, and 13 are covered with the mattress cover 2, spaces of predetermined widths w1, w2, w3, and w4 and predetermined depths d1, d2, d3, and d4 are formed on the back side of the mattress cover 2, allowing sweat and the like to dry more quickly.

[0043] As described above, the mattress 1 is configured such that a base layer 3 harder than the surface layer 4 is attached to the underside of the surface layer 4, and a plurality of grooves 11, 13 of predetermined widths w3, w4 and depths d3, d4 that do not reach the base layer 3 are provided in the surface layer 4 at positions corresponding to the back and / or buttocks and / or heels of the recumbent person 6, extending widthwise.

[0044] Therefore, the mattress 1 having the above configuration can more flexibly receive the body weight of the reclining person 6 at positions corresponding to the buttocks and heels, improving the sleeping comfort, and since the grooves 11, 13 do not reach the base layer 3, which is harder than the surface layer 4, the mattress 1 can be prevented from breaking even if it is repeatedly subjected to the body pressure of the reclining person 6 or if repeated force is applied during cleaning.

[0045] In addition, the mattress 1 can be turned over for use by attaching a back layer 5, which is harder than the surface layer 4, to the underside of the base layer 3, and is configured to have a plurality of grooves 15, each having a predetermined width w5 and a depth d5 ​​that does not reach the base layer 3, extending widthwise at a position on the back layer 5 corresponding to the knees of the recumbent 6.

[0046] Therefore, with the mattress 1 having the above configuration, even when the mattress is turned over and the user lies on the back surface layer 5 side, the flexibility of the knees can be maintained without impairing the comfort of sleeping due to the hardness of the back surface layer 5.

[0047] In addition, the mattress 1 is provided with a removable mattress cover 2 that is water-absorbent and / or hydrophilic, and the grooves 11, 13, and 15 are covered with the mattress cover 2, so that spaces are formed by the grooves 11, 13, and 15 below the mattress cover 2, allowing moisture such as sweat to dry more quickly.

[0048] In addition, the above-mentioned mattress 1 is configured so that the entire rectangular, elongated mattress 1 is covered with a mattress cover 2, and handles 23, 24 are provided at the front end and center of the long sides of the mattress cover 2, respectively, so that the mattress 1 can be bent between the handle 23 at the front end and the handle 24 at the center, allowing the handle 23 at the front end and the handle 24 at the center of the mattress cover 2 to be held with one hand.

[0049] Therefore, with the mattress 1 configured as described above, the mattress 1 overlaps only on the front side of the handles 23, 24, and does not overlap on the rear side of the handles 23, 24. The mattress 1 can be transported by the carrier standing on the rear side of the handles 23, 24 and holding the handles 23, 24 in front of the carrier. This reduces the width occupied during transport, and the mattress can be transported in narrow spaces as long as there is a width equal to the carrier's body and the thickness of one mattress 1, thereby improving workability and safety during transport.

[0050] Furthermore, the mattress 1 is configured such that easily bendable bending portions 8, 10 are formed at positions between the handle 23 on the front end side and the handle 24 on the central side of the mattress 1.

[0051] Therefore, with the mattress 1 configured as described above, the mattress 1 can be easily bent at the bending portions 8, 10 during transport, and the handle 23 on the front end side and the handle 24 on the central side of the mattress cover 2 can be grasped with one hand.

[0052] In addition, the mattress 1 has grooves 7, 9 extending widthwise alternately on the front and back surfaces of the mattress 1 to form bending portions 8, 10, allowing the mattress 1 to be bent to either the front or back side at the bending portions 8, 10.

[0053] Therefore, the mattress 1 having the above configuration can be transported by changing the bent posture of the mattress 1 depending on the dominant arm of the transporter and the condition of the passageway along which the mattress 1 is being transported. [Explanation of symbols]
