Description

The present invention relates to a mattress that is completely covered with a mattress cover.

Mattresses used at home, in hospitals, nursing homes, etc. have handles on the mattress cover that covers the entire mattress to make them easier to transport for cleaning, installation, etc.

Conventional mattresses have handles symmetrically provided on the front and back of the long sides of the mattress cover, and the carrier holds the front and back handles with both hands to carry the mattress (see, for example, Patent Document 1).

Japanese Patent Application Publication No. 9-276083

However, with conventional mattresses, the mattress carrier had to carry the mattress while grasping the handles located at symmetrical positions on the front and back of the long sides of the mattress cover with both hands, which forced the carrier to carry the mattress in an awkward position.

As a result, conventional mattresses are difficult to transport and set up 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.

Therefore, in the present invention of claim 1, 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, so that the mattress can be bent between the handle on the front end and the handle on the central side and the handle on the mattress cover can be held with one hand.A bending portion is formed by providing grooves extending left and right on the front and back surfaces only at the position between the handle on the front end and the handle on the central side, so that the mattress can be bent to either the front or back side at the position between the handle on the front end and the handle on the central side.

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 central side corresponds to the back of a person lying down, and grooves extending left and right are provided on the front and back side only at that position to form a bent portion, and grooves extending left and right are provided on the front side only at positions corresponding to the buttocks and heels of a person lying down to form a bent portion.

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 at a position corresponding to the back of a reclining person, grooves extending in the width direction to a depth that reaches all the way to the base layer are alternately provided in the surface layer and back layer to form a curved portion, and at a position corresponding to the buttocks and heels of a reclining person, grooves extending in the width direction to a depth that does not reach all the way to the base layer are provided only in the surface layer to form a curved portion .

The present invention achieves the following effects:

In other words, in this invention, the entire rectangular, elongated mattress is covered with a mattress cover, and handles are provided on the front and center long sides of the mattress cover. The mattress is bent between the front and center handles so that the front and center handles of the mattress cover can be grasped with one hand. As a result, the mattresses overlap only in front of the center handle and do not overlap behind the center handle. This allows the carrier to transport the mattress while standing behind the center handle and grasping both handles in front of them. This reduces the width occupied during transportation, improving workability and safety during transportation.

In particular, if an easily bendable bendable section is formed between the front handle and the central handle of the mattress, the mattress can be easily bent at the bend section during transport, allowing the front handle and the central handle of the mattress cover to be grasped with one hand.

Furthermore, if the bendable portion is formed by alternately providing grooves extending in the width direction on the front and back surfaces of the mattress, and the mattress can be bent to either the front or back at the bendable portion, the mattress can be transported in a different bent position depending on the carrier's dominant hand and the condition of the passageway along which it is being transported.

1A is a plan view showing a mattress and a mattress cover, and FIG. 1B is a side view showing the mattress and a mattress cover. 1A is a plan view, FIG. 1B is a side view, and FIG. 1C is a bottom view showing a mattress. FIG. FIG. FIG. 2 is an explanatory diagram showing the shape of the mattress when transported.

The specific configuration of the mattress according to the present invention will be explained below with reference to the drawings.

As shown in Figure 1, the mattress 1 is an elongated rectangular plate made of elastic urethane resin or the like, and is entirely covered with a removable mattress cover 2.

As shown in Figures 1 and 2, the mattress 1 has a base layer 3 in the shape of a vertically elongated 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.

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. It can also be used upside down; if a softer sleeping experience is preferred, the surface layer 4 side is used on top, and if a firmer sleeping experience is preferred, the back layer 5 side is used on top.

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

These grooves 7 have a constant width w1 in the front-to-rear direction, and are formed to a depth d1 that extends from the top surface of the surface layer 4 to the middle of the base layer 3. They are arranged parallel to each other at a constant interval t1 in the front-to-rear direction (Figure 3(a)).

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

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

These grooves 9 have a constant width w2 in the front-to-back direction, and are formed to a depth d2 that extends from the lower end surface of the back layer 5 to the middle of the base layer 3. They are arranged in parallel in the front-to-back direction at a constant spacing t2 (Figure 3(a)). Here, the spacing t1 of the grooves 7 formed in the surface layer 4 and the spacing t2 of the grooves 9 formed in the back layer 5 are made the same, and the grooves 7 on the surface layer 4 and the grooves 9 on the back layer 5 are alternately arranged so that the grooves 9 on the back layer 5 are located between adjacent grooves 7, 7 on the surface layer 4, creating an overall bellows-like shape.

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 recumbent person 6 (the front end of the mattress 1). This bent portion 10 also functions as a body pressure reduction portion in the back surface layer 5 that can reduce body pressure on the back of the recumbent person 6.

The mattress 1 also has multiple 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.

These grooves 11 have a constant width w3 in the front-to-rear direction, and are formed to 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. They are arranged parallel to each other at a constant interval t3 in the front-to-rear direction (Figure 3(b)).

As a result, the mattress 1 has a body pressure reduction section 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.

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

These grooves 13 have a constant width w4 in the front-to-rear direction, and are formed to 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. They are arranged parallel to each other at a constant interval t4 in the front-to-rear direction (Figure 3(d)).

As a result, the mattress 1 has a body pressure reducing section 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.

Furthermore, the mattress 1 has multiple grooves 15 formed in the back 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) that extend across the entire width from the left end to the right end. Forming multiple grooves 15 in the back layer 5, which is harder than the surface layer 4, reduces the firmness of the mattress. However, by forming grooves 15 behind the knees of the reclining person 6, who has less contact with the mattress 1 (back layer 5) when lying on the back layer 5 side, the reduction in firmness of the back layer 5 due to the formation of the grooves 15 is less noticeable, and sleeping comfort on the back layer 5 is not impaired.

These grooves 15 have a constant width w5 in the front-to-rear direction, and are formed with a depth d5 extending 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. They are arranged parallel to each other at a constant interval t5 in the front-to-rear direction (Figure 3(c)).

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

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 tilt up relative to the buttocks support 18, the bent section 16 is located above the bent section between the thigh support 21 and lower leg support 22 which tilt up 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, and 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 mattress 1's ability to follow the user's movements when the bed 1 is reclined is improved, preventing the recumbent's 6 body from slipping and placing stress on the body.

In the 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, and having a depth that does not reach the base layer 3. However, this is not limited to this, and the grooves may be formed in positions in the surface layer 4 corresponding to the back and/or buttocks and/or heels of the recumbent 6.

As shown in Figure 1, the mattress cover 2 that covers the mattress 1 is provided with a pair of handles 23, 24 for use during transportation.

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

As shown in Figure 5, by bending the mattress 1 between the front handle 23 and the central handle 24 of the mattress cover 2, the front handle 23 and the central handle 24 of the mattress cover 2 can be overlapped, allowing both handles 23, 24 to be held with one hand.

As a result, when the handle 23 on the front end of the mattress cover 2 and the handle 24 on the center side are overlapped, the mattress 1 overlaps only on the front side of both handles 23, 24, and the mattress 1 does not overlap on the rear side of both handles 23, 24. This allows the carrier to transport the mattress 1 while standing behind both handles 23, 24 and holding both handles 23, 24 in front of the carrier.

In particular, in the mattress 1, the bent portion 8 of the surface layer 4 and the bent portion 10 of the back layer 5 are formed at positions corresponding to the positions between the front handle 23 and the central handle 24 of the mattress cover 2. This allows the mattress 1 to be easily bent between the front handle 23 and the central handle 24, and also allows the mattress 1 to be easily bent either toward the surface layer 4 (Figure 5(a)) or toward the back layer 5 (Figures 5(b) and (c)).

This mattress cover 2 can be made of a material that is water-absorbent and hydrophilic. Even if moisture from drinks or sweat drips onto the mattress cover 2, the absorbency of the mattress cover 2 will absorb the moisture, and the hydrophilic properties of the mattress cover 2 will 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 rather than the conventional nylon, it is possible to apply a flame-retardant (fire-resistant) agent mixed with polyurethane and then apply it to the base fabric, resulting in a hydrophilic finish that also provides flame retardancy.

In particular, the mattress 1 has grooves 7, 9, 11, and 13 formed in positions corresponding to the back, buttocks, and heels of the recumbent person 6, where the body pressure is greater than in other areas. When the grooves 7, 9, 11, and 13 are covered with the mattress cover 2, spaces of specified widths w1, w2, w3, and w4 and specified depths d1, d2, d3, and d4 are formed on the back side of the mattress cover 2, allowing sweat and other substances to dry more quickly.

As explained above, the mattress 1 has a base layer 3, which is harder than the surface layer 4, attached to the underside of the surface layer 4, and multiple grooves 11, 13, each with a predetermined width w3, w4 and a depth d3, d4 that does not reach the base layer 3, extending widthwise in the surface layer 4 at positions corresponding to the back and/or buttocks and/or heels of the recumbent 6.

As a result, the mattress 1 configured as described above can more flexibly absorb the body weight of the reclining person 6 at positions corresponding to the buttocks and heels, improving sleeping comfort. Furthermore, because 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.

The mattress 1 can be turned over and used by attaching a back layer 5, which is harder than the top layer 4, to the underside of the base layer 3. The back layer 5 has multiple grooves 15, each with a predetermined width w5 and a depth d5 that do not reach the base layer 3, extending widthwise at positions corresponding to the knees of the recumbent person 6.

As a result, with the mattress 1 configured as described above, even when the mattress is turned over and the user lies on the back surface layer 5 side, flexibility in the knee area can be maintained without compromising the comfort of sleeping due to the hardness of the back surface layer 5.

The mattress 1 is also provided with a removable absorbent and/or hydrophilic mattress cover 2, which covers the grooves 11, 13, and 15. This creates space beneath the mattress cover 2 due to the grooves 11, 13, and 15, allowing moisture such as sweat to dry more quickly.

The above-mentioned mattress 1 is configured so that the entire rectangular, vertically elongated mattress 1 is covered with a mattress cover 2, and handles 23, 24 are provided on the front and center sides of the long sides of the mattress cover 2, respectively. The mattress 1 is bent between the front handle 23 and the center handle 24, allowing the front handle 23 and the center handle 24 of the mattress cover 2 to be grasped with one hand.

As a result, 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 carrier can transport the mattress 1 while standing on the rear side of the handles 23, 24 and grasping the handles 23, 24 in front of the carrier. This reduces the width occupied during transport, and allows the mattress to be transported in narrow spaces as long as the width is equal to the carrier's body and the thickness of one mattress 1, improving workability and safety during transport.

The mattress 1 is also configured with easily bendable bending sections 8, 10 formed between the handle 23 on the front end side and the handle 24 on the center side of the mattress 1.

As a result, with the mattress 1 configured as described above, the mattress 1 can be easily bent at the bending portions 8, 10 during transport, allowing the handle 23 on the front end side and the handle 24 on the center side of the mattress cover 2 to be grasped with one hand.

The mattress 1 also has grooves 7, 9 extending in the width direction alternately provided 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 at the bending portions 8, 10.

As a result, with the mattress 1 configured as described above, the bent posture of the mattress 1 can be changed for transport depending on the carrier's dominant arm, the condition of the passageway, etc.
