First, the mattress and the test bed will be described.

(mattress)
As shown in FIG. 1A, a mattress (bedding) 1 is formed in a three-layer structure in the vertical direction, and an upper cushion layer 2 disposed on the upper side and a lower cushion disposed on the lower side. It is comprised from the layer 3 and the center core 4 arrange | positioned between the upper side cushion layer 2 and the lower side cushion layer 3. As shown in FIG.
The upper cushion layer 2 and the lower cushion layer 3 are formed in a structure in which cotton is accommodated in a bag body.

As shown in FIGS. 1 (a) and 1 (b), the core 4 is divided into three in the length direction of the mattress 1 (see FIG. 1 (a)), the first to third cores 11a and 11b. 11c, and these first to third core members 11a, 11b, 11c are accommodated in a cover (not shown) arranged in the length direction of the mattress 1 (the direction of arrow A in the figure). Yes.
When a user (not shown) lies on the mattress 1, the first to third core members 11 a, 11 b, and 11 c are positioned on the user's head side, and the second core member 11 b The third core member 11c is located on the user's foot side.

Each of the first to third core members 11a, 11b, and 11c is made of polyester hard cotton, is formed in a flat plate shape, and has a large number of through holes 12 penetrating in the thickness direction.
The through holes 12 are formed in a state of being arranged in 12 rows and 6 columns in the first to third core members 11a, 11b, and 11c, respectively. Here, the length direction of the mattress 1 is a row, and the width direction is a column.

And as shown in FIG. The through-hole 12 is configured such that a columnar body 13 formed in a columnar shape with a polyethylene harder than the first to third core members 11a, 11b, and 11c can be fitted. In the present embodiment, the through hole 12 is formed in a cylindrical shape, and the columnar body 13 is formed in a columnar shape corresponding to the inside of the through hole 12.
In addition, the 1st thru | or 3rd core material 11a, 11b, 11c may be formed other than the polyester hard cotton. Further, the columnar body 13 may be formed of a material other than the polyethylene as long as it is formed of a material harder than the first to third core members 11a, 11b, and 11c.

Then, by fitting the columnar body 13 into the through holes 12 of the first to third core members 11a, 11b, and 11c, the hardness of the core 4 can be increased, and the core 4 can be bent. Can be suppressed.

In this case, the columnar body 13 may be inserted into the through hole 12 arranged in this portion.

Furthermore, the hardness of the first to third core members 11a, 11b, and 11c can be finely adjusted by selecting from a plurality of columnar bodies 13 having different hardnesses and fitting them into the through holes 12.
In the present embodiment, two types of columnar bodies 13 having different hardnesses are formed by changing the foaming ratio of the polyethylene forming the columnar body 13. Of the two types of columnar bodies 13, one having a relatively low hardness is defined as a first columnar body 13a, and the other having a relatively high hardness is defined as a second columnar body 13b.

  In the present embodiment, three types of cores 4 in which the position and number of the through holes 12 into which the columnar bodies 13 are inserted and the hardness of the columnar bodies 13 are changed are formed. The three types of cores 4 are the regular 14 shown in FIG. 2, the middle 15 shown in FIG. 3, and the hardware 16 shown in FIG. 4. The middle 15 is formed to be harder than the regular 14, and the hard 16 is the middle 15 It is formed to be harder than that.

  As shown in FIG. 2, the regular 14 is arranged in the through holes 12 located in the 4th to 9th rows and in the 4th to 6th rows among the many through holes 12 formed in the first core member 11a. The first columnar body 13a is inserted into the through-holes 12 located in the 4th to 9th rows and the 2nd to 5th rows among the many through holes 12 formed in the second core member 11b. 13a is inserted. The through hole 12 of the third core member 11c is an empty portion because the columnar body 13 is not inserted.

  Moreover, as shown in FIG. 3, the middle 15 is located in 4-9 rows among the many through holes 12 formed in the first core member 11a and in the through holes 12 located in 4-6 rows. The first columnar body 13a is inserted into all the through holes 12 located in rows 4, 5, 8, and 9 among the many through holes 12 formed in the second core member 11b. The second columnar bodies 13b are inserted into all the through holes 12 that are inserted and located in the sixth and seventh rows. The through-hole 12 of the third core member 11c is an empty portion because the columnar body 13 is not inserted.

  Moreover, as shown in FIG. 4, the hard 16 is located in 3-5, 8-10 rows, and is located in 4-6 columns among many through-holes 12 formed in the 1st core material 11a. The first columnar bodies 13a are inserted into the through holes 12, and the second columnar bodies 13b are inserted into the through holes 12 located in the 6th and 7th rows and located in the 4th to 6th columns. Moreover, the 1st columnar body 13a is inserted in all the through-holes 12 located in 3-5, 8-10 rows among many through-holes 12 formed in the 2nd core material 11b, and it is in 6th, 7th rows. The second columnar body 13b is inserted in all the through holes 12 positioned. The through-hole 12 of the third core member 11c is an empty portion because the columnar body 13 is not inserted.

(Test bed)
As shown in FIGS. 5A and 5B, the test bed 21 is disposed on the floor 22 and the frame 22 so that a user not shown in plan view can lie on his back. The top board 23 formed in the rectangular shape of a magnitude | size and the pad 24 (refer FIG.5 (b)) arrange | positioned on the top board 23 are provided.

The top plate 23 is divided into four parts in the longitudinal direction (the height direction when the user lies down), and the first top plate (first division part) 23a where the head of the user lying down is located The second top plate (divided portion) 23b where the shoulder portion is located, the third top plate (divided portion) 23c where the waist portion is located, and the fourth top plate (divided portion) 23d where the leg portion is located. ing.
The height of the first top plate 23a can be changed by lifting means 25 described later. On the other hand, the heights of the second, third, and fourth top plates 23b, 23c, and 23d are fixed, and they are all installed at substantially the same height.

The pad 24 includes a first pad 24a disposed on the first top plate 23a and a second pad 24b disposed on the second to fourth top plates 23b, 23c, and 23d. Yes.
The first pad 24a and the second pad 24b are separated.
For example, the first pad 24a and the second pad 24b are formed by filling a bag with a synthetic resin foam, natural fiber, synthetic fiber, or the like, and have the same thickness.

  The test bed 21 is connected to the lifting means 25 for moving the first top plate 23a up and down to a desired height, and the first to fourth top plates 23a to 23d, respectively. The weight measuring means 26 which can measure the weight of the user's body part arranged on the upper part and the selection means 27 which selects the core 4 of the mattress 1 suitable for the user are provided.

The selection means 27 is a means for inputting the weight of each part of the user's body measured by the weight measurement means 26 and calculating the ratio of the weight of the user and the weight of each part of the user's body; Means for selecting a core 4 (see FIG. 1) suitable for the user from the weight and height of the mattress.
The height of the user is input by the person who operates the test bed 21 or the user.
In the selection means 27, the regular 14 (see FIG. 2) is created based on the table showing the relationship between the weight and height of the user and the optimum core 4 for the user, which is produced from the past data shown in FIG. ) The optimum one is selected from the three types of cores 4 of the middle 15 (see FIG. 3) and the hardware 16 (see FIG. 4).

(Bedding selection method)
Next, a bedding selection method will be described.

(Head height determination step)
Determine the height of the user's head.
First, a user is laid down on the test bed 21 shown in FIG. At this time, the user's head is positioned on the first top plate 23a, the shoulder is positioned on the second top plate 23b, and the user's neck is positioned on the first top plate 23a and the second top plate 23b. Position it at the border. At this time, the first top plate 23a is installed at the same height as the second top plate 23b.

Next, the 1st top plate 23a is raised with the raising / lowering means 25, and a user's favorite height is determined. This height corresponds to the height of the user's pillow.
In addition, it is preferable to set this height to the height at which the axis of the user's head lying horizontally is horizontal.

(Measurement step)
Subsequently, the weight of the user and the weight of each part of the user's body are measured.
The weight of each part of the user's body is measured by the weight measuring means 26 connected to the first to fourth top plates 23a to 23d while the user is lying down. At this time, the first top plate 23a has a height determined in the head height determining step.

The weight measuring means 26 connected to the first top plate 23a measures the weight of the user's head, and the weight measuring means 26 connected to the second top plate 23b is applied to the shoulder and the third top plate 23c. The connected weight measuring means 26 measures the weight of the waist, and the weight measuring means 26 connected to the fourth top plate 23d measures the weight of the leg. These measurement data are input to the selection means 27, and the ratio of the weight of the user, which is the sum of these weights, and the weight of the user's head, shoulder, waist, and leg is calculated. This ratio is expressed as a percentage, for example.
Also, the height of the user is input to the selection means 27 before and after this measurement step.

(Selection step)
Subsequently, the core 4 (see FIG. 1) suitable for the user is selected by the selecting means 27 so that the regular core 14 (see FIG. 2), the middle 15 (see FIG. 3), and the hardware 16 (see FIG. 3). (See FIG. 4).

(Adjustment step)
Subsequently, the core 4 selected in the selection step is adjusted.
The adjustment of the core 4 is performed based on the weight ratio of the user's head, shoulders, waist, and legs.
Since the ratio of the weight of the user's head, shoulder, waist, and leg is generally a value that approximates 7: 33: 44: 16, the high specific gravity part and the low specific part based on this ratio If there is, adjust the hardness of the core material corresponding to this part. The reference ratio may be a ratio other than this.

  For example, when the regular 14 is selected for the core 4 in the selection step and the weight ratio of the user's head, shoulder, waist, and leg is calculated as 5: 40: 40: 15 in the measurement step, Of the first columnar bodies 13a inserted in the through holes 13 of the two-core material 11b, for example, five first columnar bodies 13a are moved to the through-holes 12 of the first core material 11a.

  Further, when the hardness of the first core material 11a is increased without changing the hardness of the second core material 11b, a new columnar body is formed in the through hole 12 in which the columnar body 13 of the first core material 11a is not inserted. 13 may be inserted to increase the hardness of the first core member 11a. Moreover, the first columnar body 13a already inserted into the through hole 12 may be changed to the second columnar body 13b to increase the hardness of the first core member 11a.

Moreover, when lowering the hardness of the second core material 11b without changing the hardness of the first core material 11a, the first columnar body 13a inserted in the through hole 12 of the second core material 11b is removed. The hardness of the second core material 11b is lowered.
At this time, when the middle 15 or the middle core 4 of the hardware 16 is selected instead of the regular 14 in the selection step, the second columnar body 13b is changed to the first columnar body 13a, and the second core material 11b The hardness may be lowered.
In the same core material, the hardness may be partially increased or decreased. Further, instead of the weight ratio of each part of the user's body, the hardness of the core 4 may be changed according to the user's body shape and preferences.

Next, the effect of the bedding selection method described above will be described with reference to the drawings.
According to the above-described bedding selection method according to the present embodiment, the center core 4 of the mattress 1 serving as a reference is selected based on the weight and height of the user, and the hardness of the core 4 is determined for each part of the user's body. By adjusting based on the weight ratio, there is an effect that the optimal mattress 1 can be selected for the user.
In addition, since the mattress 1 includes the center core 4 and the columnar body 13 that is inserted into the through hole 12 formed in the center core 4, the hardness of the center core 4 can be easily adjusted.

In addition, since it is possible to determine the optimal head height of the user and to calculate the weight ratio of each part of the user's body with the user's head held at this height, The mattress 1 that is more optimal for the user can be selected.
Also, the height of the user's pillow can be determined.

As mentioned above, although embodiment of the bedding selection method by this invention was described, this invention is not limited to said embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, although the bedding selection method according to the present embodiment includes the head height determination step, the measurement step may be performed without determining the head height.
In the embodiment described above, the mattress 1 is selected. However, instead of the mattress 1, a plurality of through holes are provided, and a columnar body equivalent to the columnar body 13 of this embodiment can be fitted. A mattress, a floor pad, or the like having a central core may be selected.
In the present embodiment, the through holes 12 are formed in the first to third core members 11a, 11b, and 11c in a state of being arranged in 12 rows and 6 columns, but the through holes 12 have 12 rows. It may be arranged other than 6 rows, or may be randomly formed without being arranged with respect to the first to third core members 11a, 11b, 11c.
