Description

This disclosure relates to bedding on which the user's body rests.

Various types of bedding have been known in the past. JP 2007-283087 A describes a mattress cover that fits the width of a mattress. The mattress cover has a pair of mattress cover pieces that are aligned along the width direction of the mattress cover. The mattress cover pieces have a cover bottom and cover side parts that form the side faces of the mattress cover.

Multiple plates extend from the inner surface of the cover side that extends along the longitudinal direction, and mattress material is accommodated between the multiple plates and between the plates and the cover side. A fastener is attached between the pair of mattress cover pieces. The distance between the pair of mattress cover pieces can be adjusted by changing the fastening position of the fastener relative to each mattress cover piece.

JP 2000-139624 A describes a futon set with variable functions. The futon set includes multiple padsacks. Each of the multiple padsacks is provided with an opening and closing fastener, and multiple refill pads are stored in the padsack when it is opened by the opening and closing fastener. Connecting fasteners are provided between the upper edges of the multiple padsacks, and the multiple padsacks are connected by these connecting fasteners.

JP 2007-283087 A JP 2000-139624 A

The mattress cover described above houses multiple cushion bodies such as mattress materials. However, gaps may form between the multiple cushion bodies. Furthermore, the multiple cushion bodies may be misaligned vertically, forming steps on the surface of the mattress. When gaps or steps form in the mattress in this way, it may cause an uncomfortable feeling to the user who rests his or her body on the mattress.

In the futon set described above, multiple padsacks are connected to each other by connecting fasteners provided between the upper edges of the multiple padsacks. However, in this futon set, the connecting fasteners are arranged along the upper edges of the padsacks, and so there is a possibility that the connecting fasteners may come into contact with the body of the user through the cover material, etc., causing the user to feel uncomfortable. As such, there is room for improvement in the comfort of the user who rests their body on the mattress.

The present disclosure aims to provide bedding that can suppress the occurrence of shifting or unevenness, reduce discomfort felt by the user, and improve sleeping comfort.

The bedding disclosed herein is a bedding on which a user's body is placed, comprising a number of block-shaped cushion bodies, a cloth bag body that houses the number of cushion bodies, and a partition member that divides the internal space of the bag body into a number of regions in which each of the number of cushion bodies is housed, and inside the bag body, the number of cushion bodies are lined up along a first direction with the partition member in between, and each of the side surfaces of the number of cushion bodies extends along a second direction that intersects the first direction, and the partition member extends along the second direction in a region that includes the center of the bag body in the second direction, allowing the block-shaped cushion bodies to be inserted and removed from the bag body, and the bag body has a top surface extending in the first and second directions and a bottom surface facing the opposite side to the top surface, and the upper edge of the partition member is joined to the top surface, and the lower edge of the partition member is joined to the bottom surface .

In this bedding, a plurality of block-shaped cushion bodies are housed inside a bag made of cloth. Inside the bag, the plurality of cushion bodies are lined up along a first direction. Inside the bag, the side surfaces of the plurality of cushion bodies extend along a second direction intersecting the first direction. The bedding includes a partition member that divides the internal space of the bag into a plurality of regions, and a cushion body is housed in each of the plurality of regions divided by the partition member. The partition member extends along the second direction, which is the direction in which each side surface of the cushion body extends. Therefore, since each cushion body is housed so that the side surface is along the partition member, the plurality of cushion bodies can be brought close to each other via the partition member, and gaps between the plurality of cushion bodies can be suppressed. Therefore, it is possible to suppress the occurrence of gaps or steps between the plurality of cushion bodies, and therefore it is possible to reduce the discomfort felt by the user. The partition member extends along the second direction in a region including the center of the bag in the second direction. Therefore, a partition member is provided at least in the center of the bag body in the second direction, and a pair of cushion bodies are housed so as to sandwich the partition member, making it possible to eliminate the need for hook-and-loop fasteners or the like to connect the multiple cushion bodies to each other. This reduces the discomfort felt by the user and improves the user's sleeping comfort.

The elasticity of the partition member may be lower than that of the bag body. In this case, the partition member can be made less susceptible to deformation than the bag body, making it even more difficult for the cushion body to shift. As a result, the cushion body can be prevented from shifting and the occurrence of steps inside the cushion body, making it even more comfortable to sleep on.

The bag body may have a fastener provided on either the top surface or the side surface of the bag body, and the fastener may have a first portion extending along a first direction and a second portion extending along a second direction from an end of the first portion in the first direction. In this case, since the fastener has a first portion extending in the first direction and a second portion extending in the second direction, the cushion body can be easily inserted and removed from the bag body.

According to the present disclosure, it is possible to suppress the occurrence of shifting or unevenness, reduce discomfort felt by the user, and improve sleeping comfort.

Below, an embodiment of the bedding according to the present disclosure will be described with reference to the drawings. Note that the bedding according to the present disclosure is not limited to the following embodiment. In the description of the drawings, the same or corresponding elements are given the same reference numerals, and duplicated descriptions will be omitted as appropriate. In addition, the drawings may be partially simplified or exaggerated to facilitate understanding, and the dimensional ratios, etc. are not limited to those shown in the drawings.

The bedding in this disclosure is bedding on which the user's body rests. In this disclosure, "user" refers to a person who uses the bedding. A "user" may be a person who purchases the bedding or a person who tries out the bedding. "Bedding" refers to something that the user's body rests against when the user rests or sleeps, and is typically a mattress, a futon, a cushion, a bed pad, a cushion, or a pillow.

The bedding includes multiple block-shaped cushion bodies. The term "cushion body" refers to an elastic body that deforms in response to an applied load. The term "block-shaped" refers to a property of being fixed in a certain shape. In other words, the "block-shaped" refers to a property of being deformed when an external force is applied, but returning to its original shape when the external force is removed. The "block-shaped" may be a plate-like or rectangular parallelepiped shape, or may be a shape that maintains these shapes.

Figure 1 is a perspective view showing the mattress 1 according to this embodiment. Figure 2 is a plan view showing the mattress 1. For example, the mattress 1 is a mattress. As shown in Figures 1 and 2, the mattress 1 has, for example, a rectangular parallelepiped shape. The mattress 1 has an upper surface 1b extending in the first direction D1 and the second direction D2, a pair of side surfaces 1c extending in the first direction D1 and the third direction D3, and a pair of side surfaces 1d extending in the second direction D2 and the third direction D3. For example, the first direction D1 is the longitudinal direction of the mattress 1, and the second direction D2 is the lateral direction (width direction) of the mattress 1. The third direction D3 is, for example, the height direction (thickness direction) of the mattress 1. The second direction D2 may be a direction that intersects with the first direction D1 and extends horizontally.

The bedding 1 has, for example, a cover 1A and a bag body 10 housed in the cover 1A. The bag body 10 houses a cushion body 20 (see FIG. 6). For example, the cover 1A houses a plurality of bag bodies 10, and the portions between the plurality of bag bodies 10 in the cover 1A are formed as folded portions 2.

The folding portion 2 is formed, for example, by a side fabric 1A that connects multiple bags 10 to each other. The folding portion 2 extends in the second direction D2 in the mattress 1, and as shown in Figures 2 and 3, the mattress 1 can be folded via the folding portion 2. As an example, the mattress 1 has two folding portions 2 and can be folded in thirds. When the mattress 1 can be folded in thirds in this way, it is easier to handle the mattress 1 compared to when it can be folded in five or six times.

Figure 4 is a perspective view that shows a schematic of an exemplary bag body 10 that is housed in the side fabric 1A. Figure 5 is a plan view that shows a schematic of the bag body 10. As shown in Figures 4 and 5, the bag body 10 has a rectangular parallelepiped shape. The bag body 10 has a top surface 11 that extends in the first direction D1 and the second direction D2, a pair of side surfaces 12 that extend in the first direction D1 and the third direction D3, and a pair of side surfaces 13 that extend in the second direction D2 and the third direction D3.

The bag body 10 is made of, for example, a mesh material. By making the bag body 10 out of a mesh material, the stretchability of the bag body 10 can be made moderate. That is, the bag body 10 can be made of a material that does not stretch too much. Furthermore, the bag body 10 can be made lighter and the breathability of the bag body 10 can be improved. The bag body 10 has a fastener 14 for opening and closing the bag body 10. Note that, when the bag body 10 is a rectangular parallelepiped, all of the faces of the bag body 10 may be made of a mesh material, or some of the faces of the bag body 10 may be made of a mesh material. In this embodiment, as an example, at least one face forming the bag body 10 is made of a mesh material.

Figure 5 shows the position of the fastener 14. The fastener 14 is formed, for example, on a pair of side surfaces 12 and 13. The fastener 14 has a pair of first portions 14b extending along the first direction D1, and a second portion 14c extending along the second direction D2 between the ends of the pair of first portions 14b.

In this case, the fastener 14 is arranged in a U-shape in plan view. By arranging the fastener 14 in a U-shape, it is easy to insert and remove the cushion body 20 into and from the inside of the bag body 10. However, the fastener 14 may also be arranged in an L-shape in plan view. The fastener 14 may also be arranged on the top surface 11. In this way, the arrangement of the fastener 14 can be changed as appropriate.

A partition member 15 is attached to the bag body 10. The partition member 15 is, for example, sewn to the bag body 10. The partition member 15 extends along the second direction D2, for example, extending linearly along the second direction D2. For example, the partition member 15 has a rectangular shape having a long side extending along the second direction D2 and a short side extending along the third direction D3.

For example, the upper edge of the partition member 15 is joined (as an example, sewn) to the top surface 11, and the lower edge of the partition member 15 is joined to the bottom surface of the bag body 10 facing the opposite side to the top surface 11. The partition member 15 extends along the second direction D2 in a region including the center C of the bag body 10 in the second direction D2.

As an example, the partition member 15 extends from one end to the other end in the second direction D2 of the bag body 10. In this embodiment, "one end" and "other end" include an end portion of something and a portion slightly shifted from the end portion. For example, the partition member 15 extends from the center of the first direction D1 on one side surface 12 to the center of the first direction D1 on the other side surface 12.

Figure 6 is a diagram showing the side surface 12 with the fastener 14 open. Figure 7 is a perspective view showing the bag body 10 with the fastener 14 open and the top surface 11 rolled up. As shown in Figures 6 and 7, the partition member 15 divides the internal space S of the bag body 10 into a plurality of areas A, and a cushion body 20 is housed in each of the divided areas A.

The partition member 15 is made of, for example, cloth. As an example, the partition member 15 has an edge portion 15b located at the end in the second direction D2, a linear portion 15c extending from the edge portion 15b in the second direction D2, and cloth portions 15d located on both sides of the linear portion 15c in the third direction D3.

For example, the thickness of the edge portion 15b and the thickness of the linear portion 15c are thicker than the thickness of the fabric portion 15d. However, the configuration of the partition member 15 is not limited to the above example and can be modified as appropriate. In addition, the mesh of the partition member 15 is finer than the mesh of the bag body 10, and the elasticity of the partition member 15 is lower than the elasticity of the bag body 10.

The cushion body 20 has a block shape. The cushion body 20 has the flexibility to deform in response to the applied load, and has the property of returning to the original shape when the load is no longer applied. The cushion body 20 is made of, for example, urethane foam. However, the cushion body 20 is not limited to urethane foam, and may be made of, for example, solid cotton, a resin material, or a mesh body. For example, the cushion body 20 has a rectangular parallelepiped shape as a whole. The cushion body 20 has an upper surface 20b facing vertically upward, a side surface 20c facing the first direction D1 and extending along the second direction D2, a side surface 20d facing the second direction D2 and extending along the first direction D1, and a bottom surface 20f facing the opposite side to the upper surface 20b.

The cushion body 20 has, for example, a plurality of protrusions 21 oriented toward one side of the third direction D3 (for example, vertically upward) and a plurality of slits 22 oriented toward the other side of the third direction D3 (for example, vertically downward). The upper surface 20b of the cushion body 20 is formed by the tops of the plurality of protrusions 21.

The multiple protrusions 21 are arranged, for example, in a lattice pattern so as to be aligned along the first direction D1 and along the second direction D2. The multiple slits 22 are aligned, for example, along the first direction D1. Each slit 22 extends, for example, along the second direction D2. As an example, each slit 22 extends linearly along the second direction D2.

For example, the slit 22 has a narrow portion 22b located on the surface (as an example, the underside) side of the cushion body 20, and an extended portion 22c located on the opposite side of the surface of the cushion body 20 from the narrow portion 22b. The width (length in the first direction D1) of the extended portion 22c is, for example, wider than the width of the narrow portion 22b.

As an example, the expansion portion 22c expands in a circular shape from the narrow portion 22b. Although an example of the cushion body 20 has been described above, the shape of the cushion body 20 is not limited to the above example and can be changed as appropriate. In other words, the cushion body 20 may be a cushion body that does not have the protrusions 21 or slits 22.

The cushion body 20 includes, for example, cushion body 20A and cushion body 20B. The type of cushion body 20A and the type of cushion body 20B are different from each other, for example, the hardness of cushion body 20A and the hardness of cushion body 20B are different from each other. In this embodiment, when it is necessary to distinguish between cushion body 20A and cushion body 20B, they are described as cushion body 20A and cushion body 20B, and when it is not necessary to distinguish between them, they are described as cushion body 20.

For example, the protrusions 21 of cushion body 20B are softer than the protrusions 21 of cushion body 20A, and cushion body 20B is softer than cushion body 20A. In this way, multiple types of cushion bodies 20, such as cushion body 20A and cushion body 20B, can be accommodated inside the bag body 10.

8 is a side view showing the bag body 10, the partition member 15, and the cushion body 20. As shown in FIG. 8, when the cushion body 20 is housed, the height H1 (length in the third direction D3) of the bag body 10 and the partition member 15 is approximately the same as the height H2 of the cushion body 20. When the cushion body 20 is housed, the length N1 of the first direction D1 of the region A is approximately the same as the length N2 of the cushion body 20 in the first direction D1. In this disclosure, "approximately the same" indicates, for example, that the difference between the larger value and the smaller value of the two values is 0 cm or more and 5 cm or less. However, the difference between the length N1 and the length N2 may be 4 cm or less, 3 cm or less, 2 cm or less, or 1 cm or less. When the difference between the length N1 and the length N2 is 5 cm or less, it is possible to suppress the formation of gaps or steps between the multiple cushion bodies 20.

When area A is open, the shape of area A defined by bag body 10 and partition member 15 is, for example, a rectangle with long sides extending in the first direction D1. Also, the shape of cushion body 20 defined by top surface 20b, pair of side surfaces 20c, and bottom surface 20f viewed along second direction D2 is, for example, a rectangle with long sides extending in first direction D1. In other words, the shape of area A viewed along second direction D2 is similar to the shape of cushion body 20 viewed along second direction D2.

As described above, when the shape of region A is similar to the shape of the cushion body 20, the height H1 and the height H2 are approximately the same, and the length N1 and the length N2 are approximately the same, the multiple cushion bodies 20 can be firmly held in the internal space S of the bag body 10. Therefore, the formation of gaps or steps between the multiple cushion bodies 20 can be suppressed. For example, the thickness of the partition member 15 is thicker than the thickness of the bag body 10. In this case, the sagging of the partition member 15 can be more reliably suppressed, so the possibility of gaps or steps occurring between the multiple cushion bodies 20 can be further reduced.

As described above, the bag body 10 can accommodate multiple types of cushion bodies 20 (e.g., cushion body 20A and cushion body 20B). In this embodiment, two cushion bodies 20 are accommodated in each bag body 10 of the mattress 1, so that the mattress 1 accommodates a total of six cushion bodies 20. In the mattress 1, the type of each of the six cushion bodies 20 can be appropriately selected. Therefore, for example, it is possible to suggest the type of cushion body 20 to be accommodated in the mattress 1 to the user of the mattress 1.

To suggest the type of cushion body 20 to be contained in the mattress 1, for example, a bedding suggestion system is used. An example of a bedding suggestion system is described below. FIG. 9 is a block diagram of a bedding suggestion system 101 according to this embodiment. The bedding suggestion system 101 includes, for example, an information terminal 102 and a server 110.

The server 110 is capable of communicating with the information terminal 102. As an example, the server 110 includes a processor (e.g., a CPU) that executes an operating system and software (applications), a main memory unit consisting of ROM and RAM, an auxiliary memory unit consisting of a hard disk or flash memory, a communication control unit consisting of a network card or wireless communication module, an input device such as a keyboard or mouse, and an output device such as a monitor. However, the configuration of the server 110 is not limited to the above and can be changed as appropriate.

Each functional element of server 110 is realized by loading specific software into a processor or memory unit (e.g., the main memory unit or auxiliary memory unit described above) and executing the software. The processor operates the communication control unit, input device, or output device described above in accordance with the software, and reads and writes data in the memory unit. Data or databases used in the processing of server 110 are stored in the memory unit.

The information terminal 102 is, for example, a device capable of executing the functions of the server 110. The information terminal 102 is, for example, a mobile terminal. "Mobile terminal" refers to a portable terminal such as, for example, a mobile phone including a smartphone, a tablet or a laptop. The information terminal 102 may be a terminal other than a mobile terminal, for example, a personal computer. For example, the information terminal 102 includes both an information terminal of a user who uses bedding, and an information terminal of a proposer who proposes bedding.

As an example, the server 110 includes, as functional components, a height input unit 111, an image acquisition unit 112, a mark display unit 113, a body position acquisition unit 114, a size calculation display unit 115, a body type pattern determination unit 116, and a cushion body data extraction unit 117. As shown in Figures 9 and 10, the height input unit 111 displays, for example, an input screen N on the information terminal 102. For example, the height input on the input screen N is transmitted to the server 110.

The height input unit 111 functions, for example, when an application provided to the information terminal 102 from the server 110 is used. The height L of the user M (see FIG. 12) may be input into the height input unit 111 by the user M or by a bedding proposer (e.g., a salesperson, a bedding provider, or a bedding advisor). Along with the input of the height L of the user M into the height input unit 111, the weight of the user M may also be input into the height input unit 111.

For example, on input screen N, weight can be input along with height L, but the input weight value is hidden (displayed with an asterisk (wildcard)). In other words, on input screen N, the person making the input can know the weight value, but those other than the person making the input cannot know the weight value. In this way, by hiding the weight value on input screen N, it is possible to prevent those other than the person making the input from knowing the weight.

The image acquisition unit 112 acquires an image of the user M's body. For example, an image of the user M's body captured by a camera (photographing unit) of the information terminal 102 is acquired by the image acquisition unit 112. As a specific example, an application is started on the information terminal 102 and an image of the user M's body is captured by the information terminal 102, so that the image acquisition unit 112 acquires the captured image of the body.

As shown in FIG. 11, the image acquisition unit 112 may acquire an image by photographing with a memory R placed behind the body of the user M. In addition, an image captured by a photographing unit other than the camera of the information terminal 102 (e.g., a camera other than the information terminal 102) may be acquired by the image acquisition unit 112.

The mark display unit 113 displays marks K indicating the position of each part of the body on the image of the information terminal 102 together with the image of the user M's body acquired by the image acquisition unit 112. For example, the mark display unit 113 displays multiple marks K for each part of the user M's body. The marks K can be moved, for example, by touching the screen of the information terminal 102 with a finger, and a part of the user M's body can be specified by moving the marks K.

In the example of FIG. 11, multiple marks K (six, for example) are displayed corresponding to the cervical vertebrae M1, back M2, waist M3, buttocks M4, backs of the knees M5, and heels M6 of the user M. For example, the bedding proposer or the user aligns each mark K with each part of the body on the image (the positions of the cervical vertebrae M1, back M2, waist M3, buttocks M4, backs of the knees M5, and heels M6, for example).

The body position acquisition unit 114 acquires the height L input by the height input unit 111 and the position of each part of the body from the body of the user M photographed by the photographing unit described above. For example, the body position acquisition unit 114 acquires the position of each part from the height L and the position of the body to which a mark K is attached on the image. In other words, the body position acquisition unit 114 acquires the position of each part of the body based on the position of the mark K that has been moved on the image.

The size calculation display unit 115 displays the size of each part of the user M's body based on the position of each part acquired by the body position acquisition unit 114. As shown in FIG. 12, the size calculation display unit 115 calculates the height L1 from the cervical vertebrae M1 to the parietal region M7, the height L2 from the back M2 to the parietal region M7, the height L3 from the waist M3 to the parietal region M7, the height L4 from the buttocks M4 to the parietal region M7, and the height L5 from the back of the knee M5 to the parietal region M7.

The height L value input by the height input unit 111 corresponds to the height from the heel M6 to the top of the head M7 on the captured image of the body. The values of the heights L1 to L5 and the lateral positions W1 to W6 described below are calculated from their ratios to the input height L. As an example, if the height L is input as 170 cm in the height input unit 111 and the ratio of the height L4 to the height L on the image is 0.5, the height L4 from the buttocks M4 to the top of the head M7 is calculated as 85 cm. In this way, the heights L1 to L5 and the lateral positions W1 to W6 are calculated from the ratios to the input height L, so that the values of the heights L1 to L5 and the lateral positions W1 to W6 can be obtained with high accuracy.

The size calculation display unit 115 may calculate at least one of the lateral position W1 of the cervical vertebrae M1, the lateral position W2 of the back M2, the lateral position W3 of the waist M3, the lateral position W4 of the buttocks M4, the lateral position W5 of the back of the knee M5, and the lateral position W6 of the heel M6. In this embodiment, "lateral position" refers to the lateral position of each part of the body, and indicates, for example, the degree to which each part protrudes and recesses in the front-to-back direction of the body.

In general, the cervical vertebrae M1 and the waist M3 are recessed toward the front of the body relative to the back M2, and the buttocks M4 protrude from the waist M3 toward the rear of the body. The backs of the knees M5 may be recessed toward the front from the buttocks M4, and the heels M6 may protrude from the backs of the knees M5 toward the rear of the body. Figure 12 shows an example in which the values of the lateral positions W1, W2, W3, W5, and W6 are positive when the value of the lateral position W4 is set to 0. That is, in the example of Figure 12, the lateral positions W1, W2, W3, W5, and W6 indicate the degree of recession toward the front of the body relative to the lateral position W4. However, the method of displaying the lateral positions W1 to W6 can be changed as appropriate.

As shown in Figures 12 and 13, the size calculation display unit 115 displays the calculated heights L1 to L5 and lateral positions W1 to W6, for example, on the screen 121. As an example, the screen 121 is a screen displayed on the display of the information terminal 102. The screen 121 displays height 121b, weight 121c, head to cervical vertebrae length 121d, lateral position of cervical vertebrae 121f, head to back length 121g, lateral position of back 121h, head to waist length 121j, lateral position of waist 121k, head to buttocks length 121m, lateral position of buttocks 121p, and head to knees length 121q.

The height L and weight entered are displayed in the height 121b and weight 121c fields, respectively. Note that the display of weight 121c may be omitted. For example, the calculated height L1 value is displayed in the head to cervical length 121d, and the calculated lateral position W1 value is displayed in the cervical lateral position 121f. The calculated height L2 value is displayed in the head to back length 121g, and the calculated lateral position W2 value is displayed in the back lateral position 121h.

The calculated value of height L3 is displayed in the head-to-waist length 121j, and the calculated value of lateral position W3 is displayed in the lateral position of the waist 121k. The calculated value of height L4 is displayed in the head-to-buttock length 121m, and the calculated value of lateral position W4 (0 as an example) is displayed in the lateral position of the buttocks 121p. The calculated value of height L5 is displayed in the head-to-knee length 121q.

As described above, the size of each part of user M's body is displayed on screen 121, allowing user M to grasp the details of his or her body size. The size calculation display unit 115 may generate a silhouette image showing user M's height L, heights L1 to L5, and lateral positions W1 to W6 as shown in FIG. 12, and display this silhouette image together with screen 121. In this case, the size of each part of user M can be displayed more clearly.

The body type pattern determination unit 116, for example, determines the body type of the user M from the positions of each part of the body acquired by the body position acquisition unit 114, and displays the determined body type. The body type pattern determination unit 116 may also determine the body type of the user M from a silhouette image generated by the size calculation display unit 115.

Figures 14(a) to 14(f) show examples of body type patterns to be determined (Type A to Type F). As shown in Figure 12 and Figures 14(a) to 14(f), Type A is a W-line type body type in which the curvature of the back M2, waist M3, and buttocks M4 is equal to or greater than a predetermined value. Type B is an S-line type body type in which the back M2 and buttocks M4 protrude beyond the waist M3, but the curvature of the back M2, waist M3, and buttocks M4 is not equal to or greater than a predetermined value.

Type C is a protruding back body type, in which the back M2 protrudes further than the buttocks M4. Type D is a hip-type body type, in which the buttocks M4 protrude further than the back M2. Type E is a flat body type, in which the curvature of the back M2, the waist M3, and the buttocks M4 are less than a specified value. Type F is a rounded back type, in which the waist M3 protrudes further than the back M2 and buttocks M4.

For example, the body type pattern determination unit 116 may determine which type of body type the user M belongs to, from type A to type F, and display the determination result on the screen 121. Note that the type of body type pattern determined by the body type pattern determination unit 116 is not limited to the above types A to F and can be changed as appropriate.

The cushion body data extraction unit 117 extracts data on the cushion body 20 contained in the mattress 1 and displays the data. "Cushion body data" indicates the type of cushion body. "Cushion body data" indicates, for example, the type of cushion body 20 suitable for the user M. "Cushion body data" indicates, as an example, the hardness (softness) of the cushion body 20 suitable for the user M. The cushion body data extraction unit 117 extracts data on the cushion body 20 of the mattress 1 from the positions of each part of the body acquired by the body position acquisition unit 114, as shown in FIG. 15, for example, and displays the data on the screen 122.

For example, the cushion body data extraction unit 117 may extract data of the cushion body 20 from a silhouette image generated by the size calculation display unit 115. The cushion body data extraction unit 117 may also extract data of the cushion body 20 from a body type pattern determined by the body type pattern determination unit 116. In this case, it becomes possible to automatically select a type of cushion body 20 suitable for the body type of the user M.

As an example, the screen 122 includes a schematic diagram 122b showing a schematic side cross section of the mattress 1, and a cushion type table 122d. However, this layout of the screen 122 is only an example and can be changed as appropriate. The schematic diagram 122b displays, for example, the layout of the cushion body 20 used by the user. In the example of FIG. 15, a schematic side cross section of a mattress divided into six areas A from the head side to the leg side is displayed.

The cushion type table 122d displays the type of cushion body 20 contained in area A of the bag body 10. As an example, the type of cushion body 20 is displayed as "fit," "hard," or "soft" for any of the fit parts, hard parts, and soft parts.

As described above, the cushion body data extraction unit 117 displays the type of cushion body 20 on the screen 122, allowing the user M to know at a glance which type of cushion body 20 is suitable for him or her. However, the data of the cushion body 20 displayed on the screen 122 is not limited to the example in FIG. 15 and can be changed as appropriate.

Next, an example of the steps of the bedding suggestion method will be described with reference to FIG. 16. Note that the steps shown in FIG. 16 are merely examples, and the method is not limited to these steps. First, for example, an application is started on the information terminal 102, and the height and weight of user M are input on the screen of the application (on the input screen N, as an example) (step S1).

Next, as shown in FIG. 11, the user M is photographed from the side while standing (step S2). At this time, a height line may be displayed. The image acquisition unit 112 acquires an image of the user M's body, and for example, the mark display unit 113 displays a number of marks K together with the image of the body on the screen of the information terminal 102. After that, the user M or the person proposing the bedding moves the marks K on the image to align the positions of the marks K with the positions of each part of the body (e.g., the cervical vertebrae M1, the back M2, the waist M3, the buttocks M4, the backs of the knees M5, and the heels M6) to perform marking (step S3).

Then, the body position acquisition unit 114 acquires the position of each part of the user M's body from the input height and the marked position on the image, and the size calculation display unit 115 calculates the size of that position. For example, as shown in Figures 12 and 13, the size calculation display unit 115 calculates each value of height L1 to L5 and lateral positions W1 to W6. The size calculation display unit 115 then displays each value of height L, weight, height L1 to L5, and lateral positions W1 to W6 in each item on the screen 121.

The body type pattern determination unit 116 determines a body type pattern from the positions of each part of the body acquired by the body position acquisition unit 114 (step S4). As illustrated in Figs. 14(a) to 14(f), the body type pattern determination unit 116 selects and displays one of types A to F from the positions of the cervical vertebrae M1, back M2, waist M3, buttocks M4, backs of the knees M5, and heels M6 acquired by the body position acquisition unit 114.

After that, for example, data on the cushion body 20 of the mattress 1 is displayed and selected (step S5). Specifically, as shown in FIG. 15, the cushion body data extraction unit 117 displays the type of cushion body 20 on the screen 122. For example, the proposer looks at the screen 122 and proposes a type of cushion body 20 that is suitable for the body of the user M, and the user M selects and decides on the cushion body 20 after listening to this proposal.

After the user M has decided on the cushion body 20, the proposer prepares the cushion body 20, places the cushion body 20 in each area A of the bag body 10, and places each bag body 10 in the cover 1A of the bedding 1. Then, the user M lies down on the bedding 1, and the proposer takes a picture of the user M's sleeping position with the information terminal 102 (step S6). After the user M and the proposer check the sleeping position obtained by this photograph, for example, the user M purchases the bedding 1, and the series of processes is completed.

Next, the effects obtained from the mattress 1 according to this embodiment will be described. As shown in Figures 6 to 8, in the mattress 1, multiple block-shaped cushion bodies 20 are housed inside a cloth bag 10. Inside the bag 10, the multiple cushion bodies 20 are lined up along a first direction D1. Inside the bag 10, the side surfaces 20c of each of the multiple cushion bodies 20 extend along a second direction D2 that intersects with the first direction D1.

The bedding 1 is provided with a partition member 15 that divides the internal space S of the bag body 10 into a plurality of areas A, and a cushion body 20 is housed in each of the plurality of areas A divided by the partition member 15. The partition member 15 extends in the second direction D2 together with each side surface 20c of the cushion body 20. Therefore, since each cushion body 20 is housed so that the side surface 20c is aligned with the partition member 15, the plurality of cushion bodies 20 can be brought close to each other via the partition member 15, and gaps between the plurality of cushion bodies 20 can be prevented.

This prevents gaps or steps from occurring between the multiple cushion bodies 20, reducing the discomfort felt by the user M. The partition member 15 extends along the second direction D2 in a region including the center C (see FIG. 4) of the bag body 10 in the second direction D2. The partition member 15 is therefore provided at least in the center C of the second direction D2 of the bag body 10, making it possible to accommodate a pair of cushion bodies 20 sandwiching the partition member 15, eliminating the need for hook-and-loop fasteners or the like for connecting the multiple cushion bodies 20 to each other. This reduces the discomfort felt by the user M, improving the user M's sleeping comfort.

As mentioned above, the elasticity of the partition member 15 may be lower than that of the bag body 10. In this case, the partition member 15 can be made less prone to deformation than the bag body 10, making it even more difficult for the cushion body 20 to shift. As a result, the cushion body 20 can be prevented from shifting and the occurrence of steps when it is housed therein, making it even more comfortable to sleep on.

4 and 5, the bag body 10 has a fastener 14 provided on either the top surface 11 or the side surfaces 12, 13 of the bag body 10, and the fastener 14 may have a first portion 14b extending along the first direction D1 and a second portion 14c extending along the second direction D2 from an end of the first portion 14b in the first direction D1. In this case, since the fastener 14 has the first portion 14b extending in the first direction D1 and the second portion 14c extending in the second direction D2, the cushion body 20 can be easily inserted and removed from the bag body 10.

In the bedding recommendation system 101 and bedding recommendation method according to this embodiment, the height L of the user M is input in the height input unit 111, and the body of the user M is photographed by the photographing unit (such as the camera of the information terminal 102). The body position acquisition unit 114 then acquires the input height L and the positions of each part of the photographed body of the user M (e.g., the cervical vertebrae M1, back M2, waist M3, buttocks M4, backs of the knees M5, and heels M6). The height L is a numerical value that is likely to be known by the user M himself, so the user M can easily input the numerical value of his or her own height L.

Therefore, the position of each part of the user M's body can be easily measured based on the input height L. In addition, since the position of each part of the body is obtained using the input height L, the position of each part can be obtained accurately based on the height L. In other words, since the positions of the cervical vertebrae M1 and back M2, etc. are obtained based on the height L, the position of each part can be obtained independently of the imaging environment and imaging conditions. As a result, the position of each part of the body can be obtained more accurately.

Furthermore, the cushion body data extraction unit 117 extracts data on the cushion body 20 of the mattress 1 (for example, data on the hardness of the cushion body 20) from the acquired positions of each part of the body, and the data on the cushion body 20 of the mattress 1 is displayed. Therefore, the user M can understand the type and arrangement of the cushion body 20 that suits him/her just by looking at the data on the image. Therefore, it is possible to adequately suggest to the user M of the mattress 1 a cushion body 20 with a hardness that suits the user M.

As described above, the cushion body data extraction unit 117 may display a cushion type table 122d indicating the type of cushion body 20 contained in the area A. In this case, the type of cushion body 20 contained in each area A of the cover 1A is displayed, so that, for example, a soft cushion body 20 (one example is "soft") or a hard cushion body 20 (one example is "hard") can be displayed. Therefore, for example, in a bedding 1 that is a pattern-ordered mattress, the arrangement of "soft", "hard", and "fit" can be freely changed, so that a bedding 1 (e.g., a mattress) that is more suitable for the user M can be suggested.

The above describes an embodiment of the bedding according to the present disclosure. However, the present disclosure is not limited to the above-described embodiment, and may be modified or applied to other things without changing the gist of the claims. In other words, the shape, size, number, material, and arrangement of each part of the bedding may be modified as appropriate without changing the gist of the above-described claims.

For example, in the above embodiment, the bedding 1 is described as having a plurality of bag bodies 10, each of which contains two cushion bodies 20. However, the bedding may also be one in which the bag bodies function as the cover. FIG. 17 is a side view that shows a schematic diagram of the bag body 40 that functions as the cover, the partition member 15, and the cushion body 20.

As shown in FIG. 17, in the bag body 40, similar to the bag body 10 described above, a partition member 15 is sewn to divide the internal space T of the bag body 40 into a plurality of regions B. When the cushion body 20 is housed, the height H3 (third direction D3) of the bag body 40 and the partition member 15 is approximately the same as the height H2 of the cushion body 20, similar to the height H1. When the cushion body 20 is housed, the length N3 of the first direction D1 of the region B is approximately the same as the length N2 of the cushion body 20 in the first direction D1.

When region B is open, the shape of region B defined by the bag body 40 and the partition member 15 is, for example, rectangular. Also, the shape of the cushion body 20 defined by the top surface 20b, the pair of side surfaces 20c, and the bottom surface 20f when viewed along the second direction D2 is, for example, rectangular. The shape of region B defined by the bag body 40 and the partition member 15 is similar to the shape defined by the top surface 20b, the pair of side surfaces 20c, and the bottom surface 20f of the cushion body 20.

As described above, when the shape of region B is similar to the above-mentioned shape of cushion body 20, height H3 is approximately equal to height H2, and length N3 is approximately equal to length N2, multiple cushion bodies 20 can be firmly held in the internal space S of bag body 40. Therefore, the formation of gaps or steps between multiple cushion bodies 20 can be suppressed, and the same effect as the above-mentioned embodiment can be obtained.

In the above embodiment, the bag body 10 is provided with a partition member 15 extending linearly in the second direction D2. However, as shown in FIG. 18(a), the bag body 50 may have a partition member 45b extending along the first direction D1 and a partition member 45c extending along the second direction D2 intersecting each other. The partition member 45b extending linearly in the first direction D1 and the partition member 45c extending linearly in the second direction D2 are joined (e.g., sewn) to the bag body 50. As with the bag body 10 described above, the bag body 50 also has the same effect as described above because the shape of each region Y inside the bag body 50 formed by the partition members 45b and 45c is similar to the shape of the cushion body 20.

In the above embodiment, the bag 10 is described with a fastener 14 that is U-shaped in plan view. However, as shown in FIG. 18(b), the bag 60 may be provided with a fastener 64 that is L-shaped in plan view. The fastener 64 has a first portion 64b that extends in the first direction D1, and a second portion 64c that extends in the second direction D2 from the end of the first portion 64b in the first direction D1. Therefore, the bag 60 can achieve the same effects as the above embodiment.

In the above embodiment, an example was described in which the bedding recommendation system 101 allows the selection of the type of cushion body 20 to be contained in the bag body 10 of the mattress 1. This bedding recommendation system and bedding recommendation method are not limited to the above embodiment and can be modified as appropriate. In the above embodiment, a bedding recommendation system 101 was described that includes a server 110 including a height input unit 111, an image acquisition unit 112, a mark display unit 113, a body position acquisition unit 114, a size calculation display unit 115, a body type pattern determination unit 116, and a cushion body data extraction unit 117, and an information terminal 102.

However, the bedding recommendation system may not have at least any of the height input unit 111, image acquisition unit 112, mark display unit 113, body position acquisition unit 114, size calculation display unit 115, body type pattern determination unit 116 and cushion body data extraction unit 117 in the server 110. In addition, the bedding recommendation system and bedding recommendation method may not have at least one of the information terminal 102 and the server 110, and the configuration for realizing the bedding recommendation system and bedding recommendation method may be changed as appropriate.

In the above embodiment, an example was described in which the body of user M is photographed using the camera function of the information terminal 102, the image acquisition unit 112 acquires the image of the body, and the body position acquisition unit 114 acquires the position of each part from the acquired image. However, the body position acquisition unit may acquire the position of each part from something other than the acquired image. For example, the body may be scanned using a 3D scanner, scanning data obtained as a result of the scanning may be input, and the body position acquisition unit may acquire the position of each part from the input scanning data. In this case, it is also possible to omit photographing the body using a camera.

In the above embodiment, an example was described in which the height H1 of the bag body 10 and the partition member 15 is approximately the same as the height H2 of the cushion body 20, and the length N1 of the region A in the first direction D1 is approximately the same as the length N2 of the cushion body 20 in the first direction D1. However, the mattress may be one in which the height of the bag body and the partition member 15 is not approximately the same as the height of the cushion body. The mattress may also be one in which the length of the region in the first direction is not approximately the same as the length of the cushion body in the first direction. Only one of the height and length of the region and the cushion body may be approximately the same as each other. Furthermore, the mattress may be one in which the shape of the region is not similar to the shape of the cushion body.

In the above embodiment, the mattress 1 that can be folded into three has been exemplified. However, the mattress according to the present disclosure may be a mattress that can be folded in two, or a mattress that can be folded into four or more. That is, the number of folding parts 2 in the mattress is not particularly limited. Furthermore, the mattress according to the present disclosure may be a mattress that cannot be folded. In the above embodiment, an example in which the mattress 1 is a mattress has been described. However, the mattress may be a mattress other than a mattress. That is, the mattress according to the present disclosure may be a futon, a cushion, a bed pad, or a pillow.
