BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bedding selection apparatus and method used when selecting a bedding having a hardness suitable for a body shape.

[0002]

2. Description of the Related Art Generally, a bed is composed of a bed frame and a mattress as bedding placed on the bed frame, and the performance of the bed depends on the body shape of the person who uses the hardness of the mattress. It depends greatly on whether or not there is.

[0003] That is, when the user lies on the mattress, the lumbar region is 2-3 with respect to the tangent line on the back of the chest and buttocks.
Constant height of cm (about half of standing position) (recessed state)
It is said that it is comfortable to sleep when it fits in.

On the other hand, when the chest and buttocks fall extremely into the mattress and the lumbar region is relatively pushed up, the user feels pain and cannot sleep. Therefore, a hard mattress is preferable in order to reduce the depression between the chest and the buttocks.

However, if the mattress is too hard, the chest and buttocks are less likely to fall, but since the body is supported only by these areas, the pressure is concentrated on the chest and buttocks, which makes it uncomfortable to sleep. It will be.

By the way, in order to select a mattress that is comfortable to sleep in, even if a mattress is selected based on a judgment such as a hard mattress or a soft mattress, the chest and buttocks are dependent on the physical condition and weight of the person using the mattress. The amount of depression varies. Therefore, the quality of a mattress is determined not only by whether the mattress is hard or soft, but also by whether the hardness of the mattress is suitable for the physique and weight of the person using the mattress.

Next, the procedure for measuring the uneven shape of the back surface of the person M to be measured using the body shape measuring apparatus 1 having the above-mentioned configuration and selecting a mattress as bedding suitable for the person M to be measured based on the measurement result will be described. To do.

First, as shown in FIG. 6A, if the person M to be measured stands on the weight scale 4 of the base 2 with the back surface facing the tip side of the sample rod 12, the first switch 42 Is operated to drive the sample frame 7 in the forward direction. When the sample frame 7 is driven in the forward direction, the sample rod 12 held by the sample frame 7 also moves integrally.
As shown in (b), the tip of each sample rod 12 contacts the back surface of the person M to be measured and is relatively displaced in the front-rear direction according to the uneven shape of the back surface.

When the sample frame 7 is driven to the forward limit and the first limit switch 23 is operated, the second drive source 29 is operated by the signal thereof to rotate the screw shaft 28, and the laser range finder 35, The movable member 33 is moved downward from above the screw shaft 28 while operating the marker 36.

By moving the movable member 33 from above to below, the amount of displacement of each sample rod 12 in the front-rear direction is measured, and the measurement signal is input to the processing device 51. The processing device 51 processes the detection signal from the sample rod 12 into the processing unit 52.
Processing is performed to obtain the back surface shape of the person M to be measured, the shape A is displayed on the monitor 57 as shown in FIG. 7, and the reference dimensions of L1, L2 and L3 shown in FIG. . Further, the obesity degree (BMI) of the person M to be measured is calculated from the height of H, which is the height of the person M to be measured, and the weight from the weight scale 4. When the height is a and the weight is b, the BMI is calculated by BMI = b / a ² and displayed on the monitor 57. Usually BM
I is 20 or less lean type, 20-24 is normal, 24-2
It is said that 6.5 is slightly obese and 26.5 or more is obese.

The above L1 is the amount of depression of the waist at the measurement point f with respect to the tangent line connecting the maximum protrusion point p of the back at the measurement point e and the maximum protrusion point t of the buttocks at the measurement point g, and this depression amount is the measurement point f. It can be obtained by the difference between the s point and the r point. The measurement point f is set from the point s, which is the maximum recessed position of the waist.

The above-mentioned L2 is the amount of protrusion of the back portion and is obtained from the difference between the q point and the p point at the measurement point e. The q point is the intersection of the tangent line connecting the o point at the measurement point d at which the neck of the person M to be measured is measured and the s point, and the measurement point e. The measurement point e is set from the maximum protruding point p on the back.

Let L be the maximum protruding point at the measurement point g of the buttocks, and let m be the point where the tangent line connecting this t point and the p point intersects the measurement point c of the head. And the maximum protrusion point n of the head. In other words, it is data necessary for selecting the height of the pillow based on the height of the head, and is not necessary as data for selecting the hardness of the mattress.

Further, the dimension from the origin (the position where the displacement amount of the detection rod 12 is 0) to the maximum protruding point or the maximum dented point at each measurement point c, d, e, f, g is h, i,
It is calculated as a value indicated by j, k, and l.

The reference dimensions L1 and L2 thus processed and calculated by the processing unit 52 and the BMI are compared by the comparing unit 53 with the set value input from the storage unit 45. That is, the reference dimensions L1 and L2 of many persons to be measured and the BM
I and I are measured, and these measured persons are made to sleep on three mattresses X to Z having different hardnesses, and the mattress of which hardness is optimum is determined. Then, data in which the mattress having the optimum hardness is associated with the reference dimensions L1, L2 and BMI is input to the storage unit 55.
Note that the hardness of the mattress is 8 when Y is 8
0 and Z are 60, and gradually become softer.

As a result, the measurement data of the person M to be measured is processed by the processor 52 and compared with the preset value by the comparator 53, so that the mattress having the hardness suitable for the person M to be measured. Can be selected. Below, BM
The values of I, L1, and L2 and the result of having the person M to be measured actually select the hardness of the mattress having a hardness suitable for themselves are shown.

If BIM is the only criterion, BMI <
In the case of 20, the mattress was Z 20 ≦ BMI ≦ 24, the mattress was Z, and when Y 24 ≦ BMI ≦ 26.5, the mattress was Y, and when X 26.5 <BMI, the mattress was X 2.

If only L1 is the criterion, L1 <3.
0, the mattress was X 3.0 <L1 <3.5, the mattress was Y 3.5 <L1, and the mattress was Z 2.

If only L2 is the criterion, L2 <4.
In the case of 5, the mattress was X 4.5 <L2 <5.0, the mattress was Y 5.0 <L2, and the mattress was Z 2.

Therefore, for example, if the hardness of the mattress in BMI is Y or Z, Y is good from L1, and Y is good from L2 according to the measurement data of the person M to be measured, overall, It is determined that the person M to be measured has a mattress with a hardness Y.

Reference dimensions L1 and L2 of the person M to be measured and BM
Although the mattress having the optimum hardness for the person M to be measured was comprehensively selected from I and I, the individual data of L1, L2 and BMI are also stored in the storage unit 55. By comparing with the individual data, a mattress having a hardness suitable for the person M to be measured can be selected.

Further, the reference dimensions L1 and L2 of the person M to be measured.
Is compared with the reference data stored in the storage unit 55,
A mattress having a hardness suitable for the person M to be measured can be selected without referring to the BMI of obesity.

Next, a second embodiment of the present invention will be described with reference to FIGS. 9 to 12. The second embodiment is a modification of the measuring means for measuring the displacement amount of the sample rod 12. The same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

That is, as shown in FIG. 8 and FIG. 9, the sample frame 7 is provided in the frame of the support 5, and the upper and lower parts of the sample frame 7 are laid along the width direction of the support 5 and the guide shaft 6 is provided.

As shown in (a), cases 62 are attached to the positions corresponding to the respective sample rods 12. This case 62 is a lower case 6 joined as shown in FIG.
A drive shaft 64 formed of 2a and an upper case 62b and having a spiral groove 63 formed on the outer peripheral surface is rotatably supported inside with its axis parallel to the sample rod 12.

A slider 65 is slidably mounted on the drive shaft 64 in a state in which its rotation is blocked by the case 62. The slider 64 is shown in FIG.
As shown in FIG. 5, a protrusion 66 that engages with the spiral groove 63 is provided so as to project, and an upper case 62b of the case 62 is provided.
The operation knob 68 is provided so as to project from the opening 67 formed along the longitudinal direction of the.

The operation knob 68 of the slider 65 is engaged with an engagement groove 71 formed in the interlocking member 69 attached to the middle portion of the sample rod 12. Therefore, when the sample rod 12 moves in the axial direction and the slider 65 is interlocked with the movement through the interlocking member 69, the drive shaft 64 is rotated. The interlocking member 6
A pair of stoppers 70 are provided on both sides of 9 to define the forward limit and the backward limit of the slide along the axial direction of the sample rod 12.

A potential meter 72 whose output voltage changes in association with the rotation of the drive shaft 64 is provided in one end of the case 62. That is, as shown in FIG. 10A, the potential meter 72 is connected to the drive shaft 64 and has a spiral having a pitch sufficiently smaller than that of the spiral groove 63 formed in the drive shaft 64. The spiral shaft 73, a brush 74 screwed to the spiral shaft 73, an electric resistance 75a with which the brush 74 contacts, and a terminal 75b electrically connected to the electric resistance 75a.
And a terminal plate 75 having

The specimen rod 12 moves to drive the drive shaft 64.
When the rotary shaft rotates, the rotation of the drive shaft 64 causes the spiral shaft 73 to rotate.
And the brush 74 moves while contacting the electric resistance 75a. Therefore, if a predetermined voltage is applied to the electric resistance 75a, the voltage value of the terminal 57b changes according to the movement of the brush 74. That is, the voltage value of the terminal 57b changes according to the amount of movement of the sample rod 12.

As shown in FIG. 8, the terminal 57b is electrically connected to a wiring board 76 provided on the closing plate 61, and a voltage is applied to the potential meter 72 via the wiring board 76, The voltage value output to the terminal 57b can be input to the processing device 51. Figure 1

Similar to the body shape measuring apparatus according to the first embodiment, it is possible to measure the uneven shape of the back surface of the person M to be measured and select a bedding having a hardness suitable for the person M to be measured based on the measurement.

Moreover, unlike the first embodiment, the laser distance meter 35 is not used, and the displacement amount of the sample rod 12 is measured by the potential meter 72. The potential meter 72 can be arranged parallel to the sample rod 12. Therefore, the dimension in the front-back direction along the moving direction of the sample rod 12 can be reduced as compared with the configuration of the first embodiment in which the laser range finder 35 has to be arranged in series with the sample rod 12. That is, the size of the device can be reduced.

The present invention is not limited to the above-mentioned one embodiment and can be variously modified. For example, the bedding may be a spring mattress, a urethane foam mattress, or a mattress made of other cushion material. In short, the present invention is not limited as long as it is a structure for elastically supporting a person to be measured. Can be applied.

In the present invention, the hardness of the mattress is set to 3
We decided to select a mattress with a hardness suitable for the person to be measured, but if the hardness of the mattress is 4 or more, a mattress with a hardness more suitable for the person to be measured is selected. Of course you can, of course.

A mattress having a hardness suitable for the person to be measured may have a predetermined hardness over the entire mattress, but as shown in FIGS. The hardness given to the user M is different depending on which one of the surface side and the other surface side is used, and the one surface and the other surface are partially harder than the other part 81. In addition, it is provided at a different position, specifically, a portion corresponding to the buttocks of the user M on one surface,

According to such a mattress 80, in the case where the user M often lie on his / her back and sleeps, FIG.
If one side of the mattress 80 is used as shown in (a), it is possible to reduce the depression of the buttocks, and when the user M often uses it in a recumbent state, the other side should be turned up. If utilized, it is possible to prevent the body from being greatly bent downward by supporting the waist and thigh.

That is, by setting the hardness of the hard portion 81 formed on one surface and the other surface of the mattress 80, it is possible for the user to lie on his back and to lie down. It can correspond to many users.

Further, the means for measuring the displacement amount of the sample rod is not limited to the laser range finder and the potential meter. For example, when each sample rod is a magnetic linear scale, the displacement amount of the sample rod is electrically measured. You may make it measure.
