Description

The present invention relates to a body surface shape measuring device, bedding, a bedding manufacturing method, a computer program, a pillow, and a pillow manufacturing method.

According to the results of the 2016 National Health and Nutrition Survey, 19.7% of people did not get enough rest through sleep in the past month, and this percentage is increasing year by year. According to the Ministry of Health, Labor and Welfare's 2014 Sleep Guidelines for Health Promotion, it has been confirmed that problems with sleep can increase anxiety and stress hormones, leading to accidents and depression. Short sleep duration and insomnia have been shown to cause problems such as obesity, hypertension, glucose intolerance, cardiovascular disease, and metabolic syndrome.
In order to improve these various sleep-related problems, consumers are considering replacing their bedding. According to a survey, ``pillows'' were cited as the number one thing and item that people pay attention to in order to have a good night's sleep.

Conventionally, various pillows have been developed to meet the demand for a good night's sleep.
Some conventional pillows have some kind of material placed on the surface to make it soft, or have a height adjustment member placed inside (for example, Patent Document 1).

JP2019-92974A

Head-body pressure can be measured by using a soft urethane pillow or a urethane-gel pillow made of urethane with gel pasted on it, and when the head is placed on it, the dispersion rate of body pressure will vary among users. It may sink too much or be too high. The same applies when a height adjusting member is arranged.
The same goes for pipe pillows; even if you control the height with the amount of pipe, they easily deform over time and the height soon no longer matches, so you have to go to the store many times to adjust them. There are services that allow you to make adjustments as many times as you like, but it is cumbersome for consumers to go to the store, which can lead to them purchasing other products.

The present invention has been made in view of the above circumstances, and provides a body surface shape measuring device, bedding, and bedding that can measure the body surface shape including the bone shape that matches the sleeping posture of an actual human body in which the force is relaxed. The purpose of the present invention is to provide a method for manufacturing a pillow, a computer program, a pillow, and a method for manufacturing a pillow.

A body surface profile device according to one aspect of the present invention includes a support base and a molding material placed on the support base to mold a portion to be measured of a human body in a sleeping position.

According to the present invention, it is possible to obtain a body surface shape including a bone shape that matches the sleeping posture of an actual human body in which the force is relaxed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on drawings showing embodiments thereof.
(Embodiment 1)
FIG. 1 is a plan view of the main body 2 and contact parts 4 and 5 according to the first embodiment, FIG. 2 is a perspective view of the main body 2 and contact parts 4 and 5, and FIG. 3 explains a method for manufacturing the contact part 4. FIG. 4 is a plan view showing the main body 2 housed in the inner cover 6, FIG. 5 is a back view showing the main body 2 housed in the inner cover 6, and FIG. 6 is a top view showing the main body 2 housed in the inner cover 6. FIG. 7 is a back view of the pillow 1 showing a state in which the inner cover 6 is accommodated in the outer cover 9, FIG. 8 is a sectional view taken along line VIII-VIII in FIG. 6, and FIG. 10 is a plan view showing the pipe accommodating portion 7, and FIG. 11 is a plan view showing the plate portion 8.
The pillow 1 includes a main body 2, contact parts 3, 4, and 5, an inner cover 6, a pipe accommodating part 7, a plate part 8, and an outer cover 9.

As shown in FIGS. 1 and 2, the main body 2 includes a synthetic resin material such as low-repulsion urethane, has a semicircular shape in plan view, and has a concave shape from both ends of the string toward the center. . The main body 2 has a shape, in the longitudinal center of the pillow 1, that approximates the sleeping position in which no force is applied, in which the spine forms a gentle S-shape when sleeping on one's back, for example. The shape of the main body 2 is preferably determined based on the shape of the average person's bones from the head to the shoulders. Note that the shape of the main body 2 is not limited to this case.
The main body 2 has a recess 21 extending in the lateral direction at the center in the longitudinal direction of the pillow 1, and has recesses 23, 23 extending in the lateral direction at both ends in the longitudinal direction.

A contact portion 3 is provided at the center of the main body 2, and contact portions 4 and 5 are fitted on both sides of the contact portion 3 into the recess 21 and recesses 23 and 23, respectively. The contact portion 3 has a shape based on the bone shape of the user's head and the supine sleeping position of the user. This shape is based on the shape of the bones from the back of the head to the neck and shoulders, the body surface shape of the skull, and the body surface shape that changes depending on the sleeping posture. The contact parts 4 and 5 each have a shape based on the bone shape of the user's head, and the left side-lying sleeping position and the right side-lying sleeping position. The contact portions 3, 4, and 5 are formed based on average head data (bone shape) of Japanese men and women, as will be described later. The above users refer to users of both genders. A plurality of types of contact parts 3, 4, and 5 may be prepared for each gender.

The contact portion 3 has a through hole 31 approximately at the center in the longitudinal direction. The recess 21 has a through hole 22 that communicates with the through hole 31 . Note that the through hole 22 may not be provided, and the lower end of the through hole 31 may be closed by the bottom surface of the recess 21. In the case of a user with a protruding back of the head, the protrusion places a load on the pillow, creating a gap between the peripheral edge of the protrusion and the pillow, causing a problem in that the line of the head, neck, and shoulders becomes convex upward. By having the through hole 31, the protruding portion fits within the through hole 31, and the above problem is solved. The ideal line of the head, neck, and shoulders can be easily formed even in people with different shapes of the back of the head. If the through hole 31 is continuous to the through hole 90 of the outer cover 9 (described later), that is, if the hole penetrates from the front side to the back side, the air permeability is good (see FIG. 8).

The contact parts 4 and 5 have through holes 41 and 51 that correspond to the shape, size, and position information of the ears when the user sleeps sideways. The recesses 23, 23 have through holes 224, 24 communicating with the through holes 41, 51.
It is preferable that the through holes 41, 51 have a shape larger than the outer edge of the user's ear by, for example, 0.5 cm to 2 cm. Thereby, it is easy to turn over and the load on the head can be well supported by the peripheral portions of the through holes 41 and 51 of the contact parts 4 and 5. It is more preferable that the through holes 41, 51 have a shape that is 1 cm to 1.5 cm larger than the outer edge.

The ears protrude from the sides of the head, and body pressure from the head is concentrated on the ears when sleeping on the side. As a result, the blood flow stops in the ears, causing the patient to turn over more often in order to keep the blood flowing, and may even wake up before or after turning over. Taking an awkward posture without crushing your ears can also cause stiffness in the muscles of your neck or shoulders. In this embodiment, the ears are accommodated in the through holes 41 and 51 corresponding to the shape, size, and position information of the user's ears, and the loads on the side of the head and cheeks are applied to the peripheral portions of the through holes 41 and 51. This problem does not occur because the information is distributed in this way. Pillows that take the ears into consideration have conventionally existed, but the above problem could not be solved because they did not take into account the size, shape, and position of the ears based on the head data.
Note that the through hole 24 may not be provided, and the lower end of the through hole 41 may be closed by the bottom surface of the recess 23.

The contact portion 3 includes, for example, a first layer 32 made of gel, a second layer 33 made of urethane, and a third layer 34 made of hard synthetic resin (see FIG. 8). Examples of the gel include elastic gels having a hardness of 0 to 12 as measured by the Japan Rubber Association standard SRIS0101. Examples of the synthetic resin include PP, PE, PC, ABS, and the like.
The contact portion 4 includes, for example, a first layer 42 made of gel, a second layer 43 made of urethane, and a third layer 44 made of hard synthetic resin (see FIG. 9).
The contact portion 5 also has the same configuration as the contact portion 4.
The contact parts 3, 4, and 5 are not limited to having the above-mentioned three-layer structure. It may have a structure of four or more layers. Furthermore, in order to adjust the shapes of the peripheral edges of the through holes 31, 41, and 51, an adjusting plate designed in a predetermined shape may be placed above or below the three-layer structure described above. As this adjustment plate, urethane, gel, other synthetic resins, etc. having different densities, specific gravity, and hardness can be used.
A plurality of first layers, second layers, and third layers of the contact parts 3, 4, and 5 are prepared, and the first layer, second layer, and third layer are selected according to each user. However, the contact portions 3, 4, and 5 can be customized by selecting adjustment plates as necessary.

Hereinafter, a method for manufacturing the contact portion 4 will be described.
For example, the average head data of Japanese men and women from the National Institute of Advanced Industrial Science and Technology is obtained.
As shown in FIG. 3, the average head data (A data) 10 is rotated using reverse engineering software such as 3D CAD software to generate leftward sideways sleeping position data, and the through hole 41 of the contact part 4 is Generate three-dimensional shape data (B data) including the following. Based on the B data based on the bone shape and sleeping posture, the first layer 42, second layer 43, third layer 44, etc. of the contact portion 4 are fabricated by NC cutting, robot arm cutting, or the like. It may also be produced by 3D printing. The adjustment plate for making corrections for each user may also be manufactured.
For example, when sleeping on your left side so that the angle between the cross section of your head taken along a line passing through the longitudinal direction of your ears and the plane of the main body 2 is 45 degrees, the height of the right peripheral edge of the through hole 41 is The shape of the peripheral edge of the through hole 41 is determined so that the height of the through hole 41 is high. Alternatively, an adjustment plate designed to increase the height of the right peripheral edge of the through hole 41 is inserted above the first layer 42 or below the second layer 43.

Alternatively, a head model may be created based on the above average head data, rolled on the main body 2, sleeping posture data may be acquired by motion capture, and B data may be generated. Alternatively, sleeping posture data of a person with an average physique may be acquired by motion capture and combined with the head data to generate B data.
Similarly, B data for the contact parts 3 and 5 is generated, and the contact parts 3 and 5 are manufactured.
The produced contact parts 3, 4, and 5 are fitted into the recesses 21, 23, and 23 of the main body 2.

As shown in FIGS. 4 and 5, the main body 2 in which the contact portions 3, 4, and 5 are fitted into the recesses 21, 23, and 23 is covered with an inner cover 6. As shown in FIGS.
The inner cover 6 has a bag shape. Various fibers can be used as the material for the inner cover 6, including natural fibers such as cotton, linen, silk, and wool, resin-based fibers such as polyester, and natural-based processed fibers such as cellulose fiber. Raw materials or processed products of natural raw materials can be used as long as they can be used as coating materials. The inner cover 6 has three through holes 60 corresponding to the through holes 31, 41, and 51.
A cylindrical portion 61 is provided in the central through hole 60 so as to extend along the through holes 31 and 22 of the contact portion 3 . The cylindrical portion 61 has a sewn portion 62 at its upper end, and the sewn portion 62 is sewn to the upper edge of the through hole 60 . The cylindrical portion 61 has a plurality of fixing portions 63 radially arranged at its lower end, and the fixing portions 63 are fixed to the back surface of the inner cover 6 by, for example, a hook-and-loop fastener structure.
Cylindrical portions 61 are similarly provided in the through holes 60 on both end sides.

As shown in FIGS. 6 and 7, the inner cover 6 is covered with the outer cover 9 with the pipe accommodating portion 7 and the plate portion 8 disposed below the inner cover 6.

As shown in FIG. 10, the pipe accommodating section 7 has a plurality of compartmentalized accommodating chambers 72 for accommodating materials such as urethane chips and soft polyester pipes. By adjusting the amount of the material accommodated in the accommodation chamber 72, the height of the pillow 1 is adjusted. The pipe accommodating portion 7 has three through holes 71 corresponding to the through holes 31, 41, and 51. Note that the number of accommodation rooms 72 is not limited to the case shown in FIG. 10.
Height adjustment can be achieved by measuring the required distance using a built-in measuring tape built into the computer program that can measure the distance between data on the screen. When using the body surface shape measuring device 14 described later, the head is lifted by the measuring section 15, so the height to be adjusted can be easily determined.

As shown in FIG. 11, the plate portion 8 is a thin plate made of, for example, urethane and has a thickness of 1 to 2 cm, and is stacked one or more times to adjust the height of the pillow 1. The plate portion 8 has a through hole 81 that corresponds to the through holes 31, 41, and 51 and extends in the longitudinal direction. In the case of a conventional urethane plate for height adjustment, the overall thickness was increased in order to move easily and maintain the shape, but in the case of the plate part 8 of this embodiment, it has a through hole 81 and a cylindrical part. 61 and 91 prevent the plate portion 8 from moving. Since the movement of the plate part 8 can be suppressed, the plate part 8 can be placed at a desired position.

The outer cover 9 has a bag shape. The outer cover 9 has three through holes 90 corresponding to the through holes 31, 41, and 51. Various fibers can be used as the material for the outer cover 9, including natural fibers such as cotton, hemp, silk, and wool, resin-based fibers such as polyester, and natural-based processed fibers such as cellulose fiber. Raw materials or processed products of natural raw materials can be used as long as they can be used as coating materials.
A cylindrical portion 91 is provided in the central through-hole 90 along the cylindrical portion 61 of the inner cover 6 . The cylindrical portion 91 is sewn to the upper edge of the through hole 90. The cylindrical portion 91 has a plurality of radially fixed portions 92 at its lower end, and the fixed portions 93 are fixed to the back surface of the outer cover 9 by, for example, a hook-and-loop fastener structure.
Cylindrical portions 91 are similarly provided in the through holes 90 on both end sides.
The tube portion 91 may have a plurality of tube lengths and gusset widths depending on the user.

As shown in FIG. 8, the through holes 22, 60, 71, 81, and 90 of the main body 2, inner cover 6, pipe accommodating portion 7, plate portion 8, and outer cover 9 are as follows: It is connected to the through hole 31. Note that in FIG. 8, the cylindrical portion 61 and the cylindrical portion 91 are omitted.

Note that in FIG. 9, the cylindrical portion 61 and the cylindrical portion 91 are omitted.

According to this embodiment, the contact portions 3, 4, and 5 provide good dispersion of body pressure along the shape of the head and maintain the shape of the sleeping position. Moreover, by using a material for the contact parts 3, 4, and 5 that can withstand changes over time, functional deterioration of the pillow over time can be suppressed.
For example, when falling asleep on your back, which is considered the ideal sleeping position, the angle between the axis of your neck and jaw and the top of the bed is approximately 15 degrees, and when falling asleep on your side, your head, neck, spine, and lumbar bones are connected in a straight line. Because of this, many people are unable to maintain their ideal sleeping position because their normal sleeping position is deviated from them for some reason. Some people find it difficult to get into their ideal sleeping position. Under the appropriate guidance of an expert, it is possible to correct the current sleeping position to the user's ideal sleeping position by adjusting the angle little by little. For example, by increasing the angle to 2 degrees or 4 degrees, you can move closer to the ideal sleeping position for the user so that he or she can sleep better while checking the S-curve of the neck and breathing. In the case of such instruction, conventionally, a new product would be purchased each time the angle is changed, but in the case of this embodiment, the user selects from among a plurality of contact parts 3, 4, 5. Alternatively, it is sufficient to simply insert the adjustment plate above or below the contact portion.

In the main body 2 according to the second embodiment, three contact portions 4 are fitted.
Similarly to the head data 10 in FIG. 3, the central abutment part 4 has an angle of 90 degrees between a cross section taken along a line passing through the longitudinal direction of the ears of the head data 10 and the plane of the main body 2. It has a shape that corresponds to the sleeping position. The contact portion 4 on the right side of FIG. 12 has a shape corresponding to a sleeping position when the cross section and the plane of the main body 2 form an angle of 45 degrees. The contact portion 4 on the left side of FIG. 12 has a shape corresponding to a sleeping position when the cross section and the plane of the main body 2 form an angle of 135 degrees.
Note that the shape is not limited to the case where the three contact parts 4 have different shapes, and the shape of the left and right contact parts 4 may be adjusted using the above-mentioned adjustment plate.

With the above structure, when a user sleeps in a side-lying position facing left, he or she initially sleeps on the central abutting portion 4 in the above-mentioned 90-degree sleeping position. When taking the above-mentioned 45-degree sleeping position, the head comes into contact with the right contact portion 4. When taking the above-mentioned 135 degree sleeping position, the head comes into contact with the left contact portion 4. Depending on the angle of sleeping on your side, you can take a good sleeping position.
By having a pillow shape that fits the user's sleeping position during the initial period of falling asleep, unnecessary tossing and turning caused by obstruction of blood circulation is reduced, and the quality of sleep is improved.

FIG. 15 is a perspective view showing the body surface shape measuring device 14, and FIG. 16 is a schematic diagram showing a state in which the body surface shape measuring device 14 is used to obtain the body surface shape of the user in a sleeping position.
The body surface shape measuring device 14 includes box-shaped support parts 141, 141, 141 that support a user in a sleeping position, and a measuring part 15.
The measurement unit 15 includes a table 151, column parts 152, 152 that can be moved up and down by an actuator, a rectangular net 153, and a net support part 154. The net support part 154 is provided at the upper end of the pillar parts 152, 152, supports both sides of the net 153, and has a U-shape in plan view with support plates 154a, 154a that move up and down according to the vertical movement of the pillar parts 152, 152. It has a shape and includes support plates 154a and a top plate 154b attached to 154a.

The net 153 is a net-like structure, has a rectangular shape, and is attached to the U-shaped inner periphery of the net support portion 154. Various fibers can be used as the material for the net 153, including natural fibers such as cotton, hemp, silk, and wool, fibers made from resin materials such as polyester, and processed fibers made from natural materials such as cellulose fibers. Processed natural raw materials can also be used as long as they can be used as coating materials. As shown in FIG. 16, the net 153 is used to closely fit the head so that the head, which protrudes horizontally from the torso, does not fall when measuring the body surface shape including the bone shape of the head. It is attached to the net support part 154 so as to have tension. Too much tension is not preferable because it will not conform to the shape and may cause pain to the person being measured. It is preferable to loosen it moderately and gently follow the human body, but it is not essential as the measurement itself is possible.
It is preferable that the mesh has a size that does not allow hair or flesh to come out. The size of the mesh is more preferably 4 mm or less on one side, and even more preferably about 2 mm on one side.
It is preferable that the surface of the object to be measured is visible through the net 153, and it is more preferable that the net 153 is thin, but is not limited thereto.
The reason why it is preferable that it is transparent is to make it easier for the person to be measured to recognize that he or she has been measured when looking at the measurement screen, but it is not essential.
The thickness affects the measured shape, and the thicker it is, the more deformed it becomes, but since the measurement itself is possible, it is not essential to make it thinner.

The support portion 141 is not limited to a box shape. The number of supporting parts 141 is not limited to three. The support part 141 is arranged to correspond to the part of the user's body that is desired to be measured.
When the part to be measured is the head, as shown in FIG. 16, the measuring part 15 is arranged at one end of the supports 141, 141, 141 arranged in the longitudinal direction so that the head faces the net 153. .
When the part to be measured is the waist, the measurement section 15 is arranged to face the waist, and the support sections 141, 141, 141 are arranged so that the measurement section 15 is sandwiched between the support sections 141, 141.

The shape of the net 153 is not limited to a square shape. It is preferable that the net 153 be thin so that the shape of the bone can be easily recognized.
For example, the support section 141 may be prepared with several types of bedding and similar samples that the user uses at home and placed thereon so that measurements can be taken in a sleeping position similar to that at home.

As shown in FIG. 16, when the user's head is opposed to the net 153 of the measurement unit 15, the part from the shoulders to the top of the head is projected from the support part 141 so as to float in the air, and the other parts of the user are placed in the support part 141. , 141, 141. Then, with the net 153 adjusted so as to follow the bone shape from the head to the base of the neck in the sleeping position, the body surface shape including the bone shape is measured by the acquisition device 11. When adjusting the net 153, it is preferable to determine the position and posture by raising and lowering the net support part 154 while checking whether breathing is easy and whether there are any parts that make sleeping uncomfortable or uncomfortable.

During the measurement, the net support section 154 is raised and lowered to adjust the relative height between the support section 141 and the measurement section 15. To enable a user to obtain a sleeping posture with a natural curve of the spine without exerting force when using a pillow 1 manufactured by taking into account the mat, mattress, etc. used by the user.
According to the body surface shape measuring device 14, it is possible to measure the nerves extending from the back of the head to the shoulders, the shape of the bones of the neck, and the surface shape of the skull. If the gap between the skull, neck bones, and nerves is comfortably filled, people can sleep with peace of mind and easily turn over. Although this gap is small and varies from person to person, it is a very important part when falling asleep.

As described above, when the pillow 1 is manufactured using the body surface shape measuring device 14, A data related to the body surface shape including the bone shape of each user's head is acquired.
The PC 12 rotates the A data using reverse engineering software such as 3D CAD software, generates data on the sleeping posture on the back, sleeping posture on the side, etc., and generates data on the three-dimensional shape of the contact parts 3, 4, and 5. (B data) is generated. Based on the B data based on this bone shape and sleeping posture, the first layer, second layer, third layer, etc. of the contact parts 3, 4, 5 are cut by NC cutting, robot arm cutting, etc., or 3D printing. Produced by etc. The adjustment plate may be manufactured and adjusted for each user.
In addition, the change in the body surface shape according to the sleeping posture is acquired as data, and the data is converted into output data (B data) such as STL data and surface data by applying reverse engineering, and the contact portion 3 is You may also create one.
The produced contact parts 3, 4, and 5 are fitted into the recesses 21, 23, and 23 of the main body 2, and the pillow 1 is manufactured.

Instead of using the body surface shape measuring device 14, data on the shape of the bones of the head may be obtained by capturing an image of the user in a standing or sitting position with a camera. When measuring the shape of the temporal region, the shape of the bones around the ears is particularly important for dispersing body pressure. Similarly, for the back of the head, if the shape of the bones from the top of the back of the head to the neck is not clear due to hair, we recommend using a swimming cap, etc. , Measure using something that can hold or gather your hair.
When a human stands, the force is applied to support the spine, and when the person sleeps, the force is relaxed and relaxed, so the human bones and muscles differ between the standing or sitting position and the lying position. have different shapes.
The human spine curves to support the standing posture, and this is a physiological phenomenon in which muscle strength works to support the body. Therefore, measure the depth of the curvature of the neck in a standing or sitting position, and then If this is reflected in the shape of the body, you may feel uncomfortable when you sleep. It is preferable to acquire the A data using the body surface shape measuring device 14. When the body surface shape measuring device 14 is used, it is possible to obtain the shape from the head to the shoulders in a suspended state when sleeping on one's back or side, that is, in a suspended state in which the force is relaxed.

It is known that by tossing and turning, humans regulate body temperature, recover from physical and mental fatigue, improve immunity, organize memory, and repair internal tissues. When using the body surface shape measuring device 14, it is necessary to take measurements in a posture that makes it easy to roll over.
When sleeping on your side, the head, neck, spine, and lumbar bones are parallel to the bottom of the bedding and are connected in a straight line as much as possible, and when sleeping on your back, the position from the neck down is on the bedding. Experiments have confirmed that it is not a painful sleeping position if the head is connected to the bottom as straight as possible, and the head is oriented at an angle slightly above the straight line.
A test was conducted to determine the angle at which it was easy to turn over. When the angle between the axis of the head and the horizontal line was in the range of 10 to 20 degrees, a comfortable pillow could be provided to all subjects. After the user takes a sleeping position, the height of the net support part 154 is adjusted and measured so that the angle does not feel uncomfortable based on the range of 10 to 20 degrees, and the rest is done when manufacturing the pillow 1. Preferably, the adjustment is performed using the pipe accommodating portion 7 and the plate portion 8.

As described above, the shapes of bones and muscles differ between standing or sitting positions and sleeping positions. In this embodiment, since the A data is acquired with the head of the user in the sleeping position floating in the air above the torso, it is possible to manufacture the pillow 1 that matches the shape of the user's actual sleeping position.

When producing a pillow 1 for a user who sleeps on his/her stomach, the body surface shape measuring device 14 acquires A data relating to the bone shape of the face from both cheeks to the bone shape from the neck to the chest when the user is lying on his or her stomach. . Then, data related to sleeping posture is acquired for each user, and B data for producing the contact portion is generated based on the acquired data. The contact part for lying on the stomach has a shape that allows the chin to be placed on the upper center of the main body 2. The pillow 1 may be designed exclusively for sleeping on the stomach, or a contact portion suitable for sleeping on the side may be made in consideration of the side sleeping position.
For users with symptoms of apnea syndrome, B Generate data.

When measuring a part to be measured other than the head, such as the waist, using the body surface shape measuring device 14, remove the top plate 154b, place the measuring part 15 so that the part to be measured faces the net 153, and The body surface shape of the part to be measured is measured by arranging the parts other than the measurement part to be supported by the support part 141.

As shown in FIG. 18, when the user lies on his or her back on the body surface shape measurement device 14, the acquisition device 11 moves from the head side to the heel side, and moves from the user's head to the neck, from the neck to the shoulder blade, The body surface shape of the measured parts is obtained from the shoulder blade to the lower back, from the lower back to the lower buttock, from the lower buttock to the lower knee, from the lower knee to the ankle, and from the ankle to the heel. For example, it is possible to attach casters to the acquisition device 11 and move the acquisition device 11 along the guide section 161 to photograph the whole body at once. It is better for casters to be able to move back and forth at the same location like a railroad track, but this is not the only option. The acquisition device 11 may be moved by an actuator.
The acquisition device 11 may be made movable other than casters; for example, the acquisition device 11 can be mounted on a drone, a pulley, a radio control, a trolley, a conveyor, etc. and used for photographing a person in a sleeping position.
In short, it is sufficient to be able to move and photograph the lower side of the user in a sleeping position.

Each part to be measured is supported by a net 156 and the body surface shape is obtained in a suspended state. A body surface shape that matches the supine sleeping position of an actual human body, where the force is relaxed, can be obtained.
The portion that protrudes below the body surface shape is the portion on which body weight (body pressure, load) is applied, and information on body pressure distribution can also be obtained satisfactorily.
A sheet for measuring body pressure distribution may be placed on the net 156 to measure the body pressure distribution in addition to the body surface shape.

The body surface shape when the user sleeps on his side or on his stomach is also obtained in the same way.
