DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cushion for preventing humiliation. More specifically, the present invention relates to a cushion for preventing humiliation and preventing moisture and heat. INDUSTRIAL APPLICABILITY The present invention is used for a mattress for bedding, a cushion body for an automobile, a cushion body for a seat, and the like.

[0002]

2. Description of the Related Art A person lying on a bed or a futon for a long time due to illness or the like tends to suffer from a disease called humiliation.
This humiliation is also called floor rubbing and easily causes fever and sepsis. The cause of the humiliation is the compressed local ischemic necrosis, and the humiliation is likely to occur at a site where a high pressure is applied by protruding bones such as the sacrum and the greater trochanter at the waist.
This necrosis occurs in a short time under high pressure and after a long time under low pressure. In order to prevent this humiliation, it is necessary to change positions within a certain time,
In addition, by suppressing the pressure applied to the sacrum or the like as low as possible, it is possible to reduce the trouble of changing the body position and suppress the occurrence thereof. When a person lies on his / her back, the pressure generated between the floor and the floor is called body pressure. It is necessary to disperse this body pressure as much as possible to keep the local pressure low. In order to disperse the body pressure, it is necessary to receive the human body with a large contact area. In addition, this body pressure is generally decomposed into vertical stress and horizontal shear force. It is said that this shear forces easily occlude blood vessels, causing local blood flow obstruction and thus necrosis.

[0003]

As described above, in a conventional mattress or the like, as shown in FIG. 16, a protruding portion 71 of a load (a human body or the like) 7 comes into contact with the mattress surface 1c, and this horizontal shearing force is applied. Necrosis easily occurs due to force. In order to prevent this, it is necessary to change the body position. Therefore, changing the body position of the person on the floor requires a great deal of labor and labor. Also, even in a conventional mattress or the like having an uneven surface, since the body is supported by the tip of the convex portion, a large load is locally applied in this case as well, and as described above, humiliation is likely to occur .

The present invention overcomes the above-mentioned drawbacks, and can suppress the onset of humiliation by uniformly supporting the body weight over a wide area and significantly reducing the load of shear stress. It is excessive to provide a cushion body for preventing humiliation which is excellent in breathability and dehumidification property and a method for manufacturing the same.

[0005]

A cushion body for preventing humiliation according to the first aspect of the present invention comprises a plate-like base layer and a plurality of columns formed on the base layer and arranged in a large number in a direction intersecting with each other. And a body-contacting plate-shaped block portion formed on the support portion and arranged in the direction intersecting with each other in a plurality of directions. The cushion member for preventing humiliation, wherein the support portion goes upward. The cross-sectional area becomes smaller in accordance with the above, and an inner space which becomes larger as going upwards is formed around the pillar portion, and the cushion body for preventing humiliation is formed in a linear manner so as to communicate with each other in the intersecting direction with each other. An internal groove is provided, and a slit-like groove is formed between the adjacent body-contacting plate-type block portions. Do Direction is linearly formed surface side groove is provided, Ri integrally construct der the above base layer and the strut portion and the body contacting plate type block portion, and the upper
The length of one side of the upper surface of the support column and the flat
The ratio to the length of one side of the lower surface of the hook portion is 1: ([39/3
5] - [79/15]) and wherein the Der Rukoto.

The “plate-like” planar shape of the “base layer” is as follows:
It is not particularly limited and variously selected depending on the purpose and application.
Usually, square (rectangular, trapezoidal, etc.) squares (mattresses for bedding, mats, backrests, etc.) or rounds (mats, etc.) are used. Usually, the shape of the “post” is preferably such that the cross-sectional area decreases continuously as it goes upward, but is not limited thereto, and may be discontinuous. The “internal space” is a space formed between the arranged columns, and communicates with the side surface of the cushion for preventing humiliation and comes into contact with the outside air. The “internal groove” is a cross-shaped linear groove connecting the internal spaces to each other. The crossing angle of the internal groove is not particularly limited, but is 90 degrees (see FIGS. 1 and 11) or 60 degrees (see FIG. 12), particularly 90 degrees.
° is preferred. Further, in the case of forming this 90 degree, it is preferable that the angle is perpendicular to the vertical and horizontal edges (outer side) of the cushion body (see FIG. 1 instead of FIG. 11). The above-mentioned “slit-shaped groove” is a slit-shaped void generated between the side surfaces of the adjacent body-contacting flat block portions. Above slit groove
And the above-mentioned internal groove has a vertical cross
In order to cut them out side by side
Can be formed. In addition, the above-mentioned “front side groove” is formed linearly by connecting adjacent slit-like grooves to each other. The support portion may be formed on the front surface of the base material layer, and may be a desired part thereof (usually a central portion (internal portion) excluding a peripheral portion of the base material layer). Can be.

The material of the base material layer, the support portion, and the body-contacting flat block portion may be any of those generally used for cushion bodies (polyurethane, synthetic rubber, natural rubber, or foams thereof). If not particularly limited, the second
As shown in the invention, those composed of foamed polyurethane are preferred. This is because they are excellent in cushioning property, strength, weather resistance, ease of production, and the like. As shown in the third invention, the internal groove and the surface-side groove may be formed by being continuously cut off in each of the intersecting directions. Further, the outer peripheral edge of the flat plate block for body contact may be tapered or rounded.

Further, it is preferable that each of the two perpendicular cross-sectional shapes of the above-mentioned support portion is the same, but the present invention is not limited to this. One vertical cross-sectional shape is different from the other vertical cross-sectional shapes perpendicular thereto. Is also good. Each of the vertical cross-sectional shapes is trapezoidal (FIG. 5).
), Deformed trapezoids with both sides constricted inside (see Fig. 6),
Alternatively, a deformed trapezoid having both sides bulging outward (see FIG. 2), and further, various deformed shapes and the like can be adopted. The cushion body for preventing humiliation of the present invention includes the above support.
The length of one side of the upper surface of the column and the flat block for body contact
The ratio to the length of one side of the part is 1: ([39/35] to [79
/ 15]), and in particular, the bottom shape of the support portion is a square, and one side thereof is 40 to 80 mm (preferably 50 to 7 mm).
0 mm), and the top surface of the pillar portion is square, and one side thereof is 15 to 40 mm (preferably 15 to 35 mm, more preferably 17 to 30 mm). It has a square shape, one side of which is 39 to 79 mm (preferably 49 to 69 mm, more preferably 54 to 64 mm), and the width of the surface-side groove is 1
４4 mm (preferably 1.5-3.5 mm, more preferably 2-3 mm).

The side of the flat plate block for body contact is 39-
The reason why the thickness is 79 mm is that if it is less than 39 mm, the strength becomes weak and deformation easily occurs.
This is because the unit to be deformed is too large to support the load uniformly. Further, the width of the above-mentioned front side groove is 1 m.
If it is less than m, it will be in contact with the adjacent flat plate block for body contact if it is deformed, and it will not be able to return to its original shape due to deformation, and if it exceeds 4 mm, it will be used for body contact The load bearing area of the flat block is reduced,
This is because the load per contact area increases significantly. Further, the reason why one side of the bottom shape of the support portion is 40 to 80 mm is that the value obtained by adding the width of the flat plate block for body contact and the width of the surface side groove is 40 to 80 mm. One side of the contact portion between the contact flat plate block and the column is 15 mm
If it is less than 40, it is easy to cause cutting damage at the contact part,
If it exceeds mm, it is difficult to incline the flat plate block for contact, and the familiarity with the contact surface such as a human body is deteriorated.

As described above, the cushion body material is not particularly limited as long as it is generally used for the cushion body (polyurethane, synthetic rubber, natural rubber, or a foam thereof), but is made of foamed polyurethane. Are preferred. This is because they are excellent in cushioning property, strength, weather resistance, ease of production, and the like. Further, as described above, the two orthogonal cross-sectional shapes of the support portion are preferably the same as described above, and furthermore, a trapezoid, a deformed trapezoid with both sides constricted inward, or a deformed trapezoid with both ends bulging outward, Various deformed shapes can be adopted. The cushion body for preventing humiliation of the present invention is suitably used particularly for a mattress for bedding.

In the present cushion body, for example, a large number of elongated one space grooves are formed in parallel in one direction (for example, the vertical direction of the vertical and horizontal directions) of a rectangular plate-shaped cushion body material. Similarly, a plurality of elongated other space grooves are formed in parallel in the intersecting direction (usually orthogonal directions, for example, the horizontal and vertical directions described above), and (1) the entire cushioning body for preventing humiliation is communicated in the intersecting direction. Internal grooves formed linearly and
And (2) a slit-shaped groove is provided between the adjacent body-contacting plate-shaped block portions, and the surface is formed linearly in the intersecting direction as a whole as a whole for preventing humiliation. It can be manufactured by providing a side groove or the like. The “one space groove” is a single long groove formed by applying a blade such as a long shape in a predetermined direction of a rectangular plate-shaped cushion body material so as to have a predetermined vertical cross-sectional shape. It is.
The “other space groove” is another elongated groove similarly formed in a direction crossing the one side surface. An internal groove is formed by one space groove and another space groove that intersect each other. The above-mentioned base material layer, the above-mentioned pillar part, the above-mentioned flat plate type block part for contact, an internal groove, a surface side groove, etc. can be the same as the above.

[0012]

In a conventional mattress, as shown in FIG. 16, a local portion (projected portion) 71 comes into contact with the mattress 1c, and the load is concentrated and supported by the projected portion 71. Forces arise. Therefore, necrosis easily occurs in the protruding portion 71. On the other hand, in the cushion body 1 for preventing humiliation, as shown in FIG. 4, a load (human body) 7 is placed on the flat plate block 4 for body contact via the base material layer 2 and the support 3. Place. At this time, the body contacting flat block 4 and the support 3 are deformed following the undulation of the load 7. This deformation occurs particularly largely at the boundary surface between the upper end of the column 3 having a narrow cross-sectional area and the flat block 4 for body contact. This deformation causes the flat plate block 4 for body contact to settle and tilt, so that the surface of the load 7 and the surface of the flat block 4 for body contact can be kept in contact with each other while always being parallel. Can be uniformly supported, and the skid of the load 7 is suppressed, and a shearing force is hardly generated. As described above, the human body is supported by the large surface area, that is, substantially the entire surface area, and the shearing force in the horizontal direction is divided, so that the occurrence of humiliation can be efficiently prevented.

Further, since the space grooves 5 and the vertical and horizontal surface grooves 6 communicating with the space grooves 5 are formed vertically and horizontally, moisture and heat existing inside are released to the outside of the cushion body. Further, the body contacting flat block 4 and the support 3 are separated from each other by the internal space 51 and the slit-like groove 61 so as not to affect each other.
Therefore, even if the loading / unloading of the load 7 is repeated, there is no possibility that the flat plate block 4 for body contact comes into contact and cannot be returned.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to embodiments and drawings. (1) Configuration of the mattress for preventing humiliation The mattress for preventing humiliation (for bedding) was formed on a flat base material layer 2 and on the base material layer 2 as shown in FIGS. It comprises a support 3 and a flat plate block 4 for body contact formed on the support 3. Base material layer 2, support 3

The internal space 51 is a gap formed between adjacent columns (for example, 3 and 3a in FIG. 3). The internal groove 5 is a linear groove connecting the internal spaces 51 to each other. The internal groove 5 communicates with the side surface of the mattress and is in contact with the outside air.

The flat plate block 4 for body contact includes the support 3
A large number are formed and arranged in directions orthogonal to each other. This is 55-60 mm in height (especially around 58 mm), 55-60 mm in width (especially around 58 mm), and thickness 1
It is a flat plate of 8 to 25 mm (especially around 20 mm), and its lower surface is connected to the upper surface of the column 3. Further, a slit-like groove 61 which is a gap between the adjacent body contacting flat block portions 4 is formed. The width of the groove 61 is 1.5
２．５2.5 mm (especially around 2 mm). The front-side groove 6 is formed such that adjacent slit-like grooves (61a, 61b, etc.) are connected to each other (see FIG. 2) and are linearly crossed. Further, an outer peripheral edge 41 of the flat plate block 4 for body contact is rounded.

(2) Manufacture of mattress for preventing humiliation The mattress 1a for preventing humiliation was manufactured as follows. An elongated cutter crossing the foamed polyurethane plate from one direction (for example, the vertical direction) of the length and width of the flat (block-shaped) foamed polyurethane plate (block) “ER-1” shown above. 2, etc., were sequentially cut and hollowed out so that the space shapes (for example, 5a and 61a in FIG. 2) shown in FIG. Thereafter, the resection direction was changed by 90 °, and similarly, from the direction orthogonal to the resection direction, the same arrow-shaped space shapes (for example, 5b and 61b in FIG. 2) were sequentially cut so as to be arranged side by side at predetermined intervals. . These are
It is preferable that a three-dimensional complicated three-dimensional shape be cut out by automatic control by NC control. As a result, the predetermined support portion 3, the body-contact flat block portion 4, the internal groove 5, and the surface groove 6 described above were formed, and the mattress 1a was manufactured. In addition, as a foamed polyurethane block, "ER-26"
Was used to produce a mattress for preventing humiliation 1b in the same manner. In addition, as this cutting machine, Albrecht Baumer
“OFS-CNC” manufactured by KG was used. In this apparatus, the above control was performed by moving the processing table and moving the blade up and down, and the blade cut sharply by rotating it. This cutting (cutting) method is not particularly limited to the above, and any method can be used as long as it can be cut into a predetermined shape, and cut into a predetermined shape using a cutting wire instead of the long blade. Is also good. Further, instead of the NC control, it may be manually cut into a predetermined shape. Further, the movement to the cutting position is not limited to the above, and only the blade may be moved,
Only the worktable may be moved. In addition, a mattress 1c of a comparative example (manufactured by Cape Co., Ltd., trade name: "Iris",
A large number of holes are formed at predetermined intervals in the vertical and horizontal directions. ) And a mattress 1d of a comparative example (trade name: “Grantex mat”, manufactured by INOAC CORPORATION), in which straight grooves are formed vertically and horizontally.).

(3) Effects of the embodiment A weight of about 5 is placed on the mattresses 1a, 1b, 1c and 1d.
A 0-55 kg person was supine, and the load distribution around the hips (from waist to thigh) was measured using a tactile sensor (manufactured by Nitta). These results are shown in FIGS.
10 and Table 2 show the results. In addition, (a) of each figure

[0020]

[Table 2]

As shown in FIG. 4, in the mattress 1 for preventing humiliation, the surface of the load is supported by the flat plate blocks 4 for body contact, so that the load can be largely dispersed. This means that, as shown in FIGS. 7B and 8B and Table 2, the frame and the pressure in the frame are the same as those in Comparative Example 1c (
Frame: 68.9 mmHg, Frame: 54.3 mmHg), Comparative Example 1d (Frame: 59.1 mmHg, Frame: 47.5 m)
mHg), the mattresses of Examples 1a and 1b have significantly lower pressures (39.5-47.6).
mmHg).

Further, the mattress according to the present embodiment is provided with an internal space having a communicating gap, so that moisture and heat such as sweat generated from the human body and the like can be released to the outside, thereby suppressing stuffiness and the like. Can be. Further, the end of the body contacting flat block 4 was pushed into the internal space 51 with a finger to check whether or not interference with the adjacent body contacting flat block 4 occurred. The body-contacting flat block portions 4 do not contact each other due to the gap of
There were no inconveniences such as the end being pushed in and not returning. In addition, this mattress is not one in which the base material layer, the above-mentioned support portion and the above-mentioned flat plate block for body contact are bonded, but because it is an integral component, each portion has a strong connection. There is no peeling of the part. Further, since the bottom and top shapes of the respective support portions and the planar shape of the flat plate block for body contact are square, the mattress according to the present embodiment can be easily removed only by removing with a predetermined cutter from the vertical and horizontal directions. Could be manufactured.

The present invention is not limited to the specific embodiments described above, but may be modified in various ways within the scope of the present invention according to the purpose and application. That is, the material, shape, size, and the like of the base material layer, the strut portion, the body-contacting flat block portion, the internal groove, the internal groove, and the front-side groove are different from those shown in the above-described embodiment. can do. Further, the planar shape and the size of the body contacting flat block portion may be changed depending on places. That is, the plane size (length and width) of the block portion can be changed depending on the location. Also, the shape of the internal groove can be changed depending on the location. Furthermore, the hardness of the material constituting the cushion body, for example, the hardness of foamed polyurethane or the like can be adjusted to various hardnesses depending on the purpose and application. Further, the outer peripheral edge of the body contacting flat block portion is rounded, but may be tapered, or further, as shown in FIG. There may be.

Further, as shown in FIG. 13, a cushion body, particularly a mat body in which no crossing grooves are formed on the outer peripheral edge portion (no grooves are formed at four corners of the peripheral edge portion) may be used. In this case, it can be manufactured by forming a long space as in the above embodiment. The mattress or the like can have a reduced processing area and can have only the used portions crossed. Further, as shown in FIG. 15, no groove is formed on the outer peripheral edge portion, and a mattress or the like formed only on the inner side thereof can be used. In this case, since there is no cut in the outer peripheral side surface, for example, it is manufactured as follows. That is, FIG.
Using a first cutter (blade) having a lateral length (L ₁ ) shorter than the lateral length of the mattress as shown in FIG. 4, a predetermined space groove and a surface side groove are formed from above to below (or in the opposite direction). (61a)

₂ , 61b ₃ ...). Thus, except for the outer circumferences (62, 63, 64, and 65) shown in FIG. 15, the intersection grooves shown in FIG. 14 are formed therein. Next, the uncut outer peripheral portions (portions corresponding to 62, 63, 64 and 65 shown in FIG. 15) are cut to the depth of the space groove. Thus, the cut space grooves and the corresponding portions of the front surface side grooves are extracted, and predetermined spaces (surface grooves and internal grooves) are formed in parallel to manufacture the present mattress and the like (see FIG. 15).
Since the mattress or the like has no groove formed on the outer peripheral edge, the processing area can be reduced, and only the used portion can be processed. Note that FIG. 13 and FIG.
In the mattress and the like shown in (1), the space between the surface grooves can be various, and the length can be changed depending on the place instead of the same space, and the vertical and horizontal lengths can be changed. Further, in the mattress or the like shown in FIG. 15, a groove shown in FIG. Further, as described above, even if the mattress or the like is not orthogonal so as to be parallel to the vertical and horizontal directions of the outer periphery, the cross shape as shown in FIGS. 11 and 12 can be employed. Also, these manufacturing methods are not limited to those described above, and various methods can be used.

[0025]

The cushion body for preventing humiliation according to the present invention uniformly supports the human body with a large surface area, that is, substantially the entire surface area, and has a horizontal shearing force, thereby reducing the generation of humiliation. Can be prevented well. Further, since the space grooves and the vertical and horizontal surface grooves communicating with the space grooves are formed vertically and horizontally, moisture and heat existing inside can be easily discharged to the outside of the cushion body, and stuffiness can be suppressed. Furthermore, the flat plate block for body contact and the strut portion are separated by the internal space and the slit-shaped groove so as not to affect each other, so that the flat plate block for body contact even when loading / unloading of the load is repeated. There is no possibility that the parts cannot be returned due to contact.
