DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Overview The following describes the present embodiment of the nap box 10 (an example of a support device, see Figs. 1A and 1B, etc.). Next, several modified examples will be described. Please note that in this specification, the same or similar symbols are used for components having similar functions in each drawing referred to in the several modified examples described later.

[0024] <<Present embodiment>> First, the configuration and function of the nap box 10 of this embodiment will be described, followed by a description of the operation of the nap box 10. Next, the effects of the nap box 10 will be described.

[0025] <Configuration and functions of the nap box> Fig. 1A is a diagram of the nap box 10 of this embodiment, and is a front view with the door 442 of the housing 40 closed. Figs. 1B and 1C are respectively front views of the nap box 10 with the door 442 open. Fig. 1D is a diagram for explaining the state in which the nap box 10 is being used by a user. Fig. 1E is a top view of a third support section 230 provided on the nap box 10. Fig. 2 is a block diagram of the control system CS of the nap box 10.

[0026] 1B, the nap box 10 of this embodiment includes a support mechanism 20, a plurality of sensors 30, a housing 40, a control unit 50, and a user interface 60 (hereinafter referred to as UI 60). The nap box 10 is a device used to support a user U (see FIG. 1D) in an upright position and allow the user U to take a nap or rest.

[0027] Here, if the user U is to take a nap or rest, it may seem appropriate to have the user U lie on his / her side using a bed or the like, rather than in an upright position. However, allowing the user U to take a nap or rest in an upright position, as in the nap box 10 of this embodiment, has two technical significances: (1) the installation area can be made smaller than that of a bed, and (2) the user U can be made to take a nap or rest at levels 1 and 2, which are the shallower levels of the four levels (levels 1 to 4) of deep sleep in non-REM sleep.

[0028] [Support mechanism, multiple sensors, and housing] The support mechanism 20 is a main part of the hardware in the nap box 10, and has a function of supporting the user U in a standing position. As shown in Figures 1B and 1C, the support mechanism 20 has a first support section 210, a second support section 220, a third support section 230, a fourth support section 240, a movement mechanism 250, and a number of pillars 260 (four pillars as an example in this embodiment). The first support part 210, the second support part 220, the third support part 230, the fourth support part 240 and the movement mechanism 250 are main components of the nap box 10 of this embodiment, and will be described later.

[0029] The multiple sensors 30 (three sensors in this embodiment) are configured with a first sensor 32, a second sensor 34, and a third sensor 36 that measure load or pressure. The multiple sensors 30 are attached to the first support section 210, the second support section 220, and the fourth support section 240, respectively (see FIGS. 1B and 1C), and are communicatively connected to the control section 50 (see FIG. 2). The first sensor 32, the second sensor 34, and the third sensor 36 each have a function of measuring the load or pressure received from the body of the user U that they are in contact with, and transmitting the measurement data to the control section 50. The first sensor 32, the second sensor 34 and the third sensor 36 are main components of the nap box 10 of this embodiment, and will be described later.

[0030] The housing 40 is the exterior of the sleeping box 10, and has the function of accommodating therein the support mechanism 20, the multiple sensors 30, the control unit 50, and the UI 60. That is, the housing 40 surrounds the support mechanism 20. As shown in FIG. 1A, the housing 40 has a ceiling wall 42, a peripheral wall 44, a bottom wall 46, and a base 48. As shown in FIG. 1A, the housing 40 has a substantially symmetrical shape when viewed from the front side of the sleeping box 10. Here, the dashed dotted line CL in the figure indicates the center line of the sleeping box 10. The ceiling wall 42 and the bottom wall 46 are each formed in a polygonal shape, for example, by diamond cutting the outer surface of a hemisphere. The peripheral wall 44 is a tube connecting the lower end of the ceiling wall 42 and the upper end of the bottom wall 46, and has a regular polygonal shape when viewed from the top-bottom direction. The peripheral wall 44 is configured by arranging multiple long plates in the circumferential direction, and a part of the wall is hollowed out to install a door 442 through which the user U can enter and exit. As one example, a double-door type door is adopted for the door 442. The base 48 supports the ceiling wall 42, the peripheral wall 44 and the bottom wall 46 from below.

[0031] As shown in Figures 1B and 1C, when viewed from the door 442 side (when viewed from the front side of the nap box 10), the multiple pillars 260 are arranged in pairs along the vertical direction on both sides of the bottom wall 46, at the front and rear, and both ends of each are fixed to the bottom wall 46 and the ceiling wall 42.

[0032] [Major components] (First support and first sensor) The first support portion 210 has a function of contacting one or both of the knee and the lower leg of the user U from the front side of the body of the user U, thereby supporting the body from below (see FIG. 1D). As shown in FIGS. 1B and 1C, the first support portion 210 includes, for example, a base 212 and a cushion 214. The base 212 is, for example, flat and rectangular when viewed in the thickness direction. As shown in Figs. 1B and 1C, the base 212 is disposed on the left side when viewed from the front side of the sleeping box 10, and is inclined so that the upper surface faces upward and toward the center line CL (inward). Therefore, the upper surface forms a slope. The inclination angle of the base 212 is, for example, set to 20° to 60°. The base 212 is fixed to a cylinder of a second actuator 254 (described later) provided in the moving mechanism 250. The cushion 214 is, for example, in the form of a flat plate, and when viewed in the thickness direction, is formed in a rectangular shape that is slightly smaller than the base 212. The cushion 214 is fixed to the upper surface of the base 212. 1B and 1C, the first sensor 32 is disposed between the base 212 and the cushion 214. The first sensor 32 measures the load or pressure received from one or both of the knee and the lower leg of the user U's body that is in contact with the cushion 214, and transmits the measurement data to the control unit 50. In this specification, when viewed from the front side of the nap box 10, the left side is defined as the front side and the right side is defined as the rear side, and the straight line connecting these is defined as the front-rear direction.

[0033] (Second support part and second sensor) The second support part 220 is positioned at a different position from the first support part 210 when viewed from the top-bottom direction (in this embodiment, at a position rearward in the front-to-back direction from the first support part 210) (see Figures 1B and 1C), and has the function of contacting one or both of the buttocks and upper thighs of the user U from the rear side of the body, thereby supporting the body from below (see Figure 1D). As shown in FIGS. 1B and 1C, the second support portion 220 includes, for example, a seat 222 and a link mechanism 224. The seat 222 has, for example, a base 222A and a cushion 222B. The seat 222 is a portion that comes into contact with one or both of the buttocks and upper thighs of the user U's body. The base 222A is, for example, flat and rectangular when viewed in the thickness direction. As shown in Figs. 1B and 1C, the base 222A is located on the right side (rear side in the front-rear direction) when viewed from the front side of the nap box 10, and is inclined so that the upper surface faces upward and toward the center line CL (inward). Therefore, the upper surface forms a slope. The upper end portion of the back surface of the base 222A is attached to the upper end of a first actuator 252 (described later) of the movement mechanism 250 so as to be able to swing. The cushion 222B is, for example, in the shape of a flat plate, and when viewed in the thickness direction, is formed in a rectangular shape that is slightly smaller than the base 222A. The cushion 222B is fixed to the upper surface of the base 222A. 1B and 1C, link mechanism 224 has a function of connecting seat 222 and first actuator 252. Link mechanism 224 has link 224A and two joints 224B fitted into through holes at both ends of link 224A. One end of link 224A is attached to a lower end portion of base 222A by joints 224B, and the other end of link 224A is attached to two adjacent pillars of multiple pillars 260 by joints 224B. With the above configuration, the seat 222 is set to change to a posture that widens the angle formed with the link 224A so as to follow the vertical direction as the seat 222 is moved upward by the first actuator 252 (see FIG. 4). The amount and range of extension / contraction of the first actuator 252 are preset. In this embodiment, the inclination angle of the seat 222 is set to, for example, 45° at its lowest limit position and, for example, 80° at its highest limit position. 1B and 1C, the second sensor 34 is disposed between the base 222A and the cushion 222B. The second sensor 34 measures the load or pressure received from one or both of the buttocks and the upper thighs of the user U's body that are in contact with the cushion 222B, and transmits the measurement data to the control unit 50.

[0034] (3rd support part) 1B and 1C, the third support section 230 is disposed at a position higher than the first support section 210 and the second support section 220. The third support section 230 has a function of contacting one or both of the upper limbs and the head of the user U's body so that the upper limbs and the head of the human body are disposed within a predetermined range in the front-rear direction, and supporting the human body from at least one side in the front-rear direction. 1B and 1C, the third support part 230 is attached to the upper end of the second actuator 254. Therefore, the third support part 230 is movable within a preset range in the up and down direction in response to the operation of the second actuator 254. As shown in Figures 1B and 1C, the third support part 230 has an attachment part 232 attached to the second actuator 254, a main body part 234 that supports the human body from the front side, and a hinge 236 (see Figure 1E). The main body 234 is attached to the attachment part 232 by a hinge 236 so as to be able to swing. As shown in FIG. 1E, the main body 234 is formed in a C-shape when viewed from above. The main body 234 has a base 234A and a cushion 234B fixed to the upper surface of the base 234A. The base 234A and the cushion 234B are formed in substantially the same C-shape. The main body 234 is designed under the idea that it is disposed at a right angle to the attachment part 232 when not in use, and that the user U tilts it when in use so that the opening side faces the vicinity of the user U's chest. The user U places both arms and head on the main body 234 when in use.

[0035] (4th support and 3rd sensor) 1B and 1C, the fourth support section 240 is disposed in a position lower than the first support section 210 and the second support section 220 and closer to the second support section 220 in the front-rear direction than the first support section 210 when viewed from the up-down direction (a position substantially directly below the second support section 220 when viewed from the up-down direction). As shown in FIG. 1D, the fourth support section 240 contacts the soles of the feet of the user U and supports the human body from below so that the feet of the human body are inclined with respect to the up-down direction. The fourth support section 240 is a V-shaped member when viewed from the front side of the sleeping box 10, and is configured with two long plates (a fixed plate and an inclined plate) extending from the front side to the back side at an angle of about 45°, for example. One of the long plates (fixed plate) is fixed to the upper surface (floor surface) of the bottom wall 46. 1B and 1C, the third sensor 36 is disposed on the inclined plate of the fourth support unit 240. The third sensor 36 measures the load or pressure applied from the foot of the user U's body that is in contact with the inclined plate, and transmits the measurement data to the control unit 50.

[0036] (Moving mechanism) As shown in FIGS. 1B and 1C, the movement mechanism 250 has a first actuator 252 and a second actuator 254. As described above, the first actuator 252 has the seat 222 of the second support section 220 attached to its upper end so as to be able to swing. The first actuator 252 has a function of changing the vertical position and inclination angle (or posture) of the seat 222 by moving the rod upward, utilizing the fact that the link 224A of the link mechanism 224 is attached to two adjacent pillars among the plurality of pillars 260. Here, in this embodiment, since the first support section 210 and the fourth support section 240 are configured not to move in the vertical direction, it can be said that the first actuator 252 has a function of moving one of the first support section 210, the second support section 220, and the fourth support section 240 (the second support section 220 as an example) in the vertical direction relative to the other one of the first support section 210, the second support section 220, and the fourth support section 240 (the first support section 210 or the fourth support section 240). As described above, the second actuator 254 has the mounting portion 232 of the third support portion 230 attached to its upper end. The second actuator 254 has a function of changing the vertical position of the third support portion 230 by moving its rod in the vertical direction.

[0037] [Control Unit] The control unit 50 has a function of controlling the moving mechanism 250 based on commands transmitted from a UI 60 (described later) and a program PG stored in a storage device 54 that the control unit 50 has. 2, the control unit 50 is communicatively connected to the UI 60, the moving mechanism 250, and the plurality of sensors 30 via an I / O port (input / output port). The control unit 50 also has a calculation device 52, a storage device 54, and a timer 56.

[0038] The arithmetic unit 52 is a so-called central processing unit, and executes a program PG stored in a first storage unit 542 of the storage device 54. The contents of the program PG will be explained in the explanation of the operation of the nap box 10, which will be described later. 2, the storage device 54 has a first storage unit 542 and a second storage unit 544. The first storage unit 542 is, for example, a read-only memory (ROM (=Read Only Memory)). The first storage unit 542 stores a program PG for operating the moving mechanism 250. The second storage unit 544 is, for example, a readable and writable memory (RAM (=Random Access Memory)). The second storage unit 544 temporarily stores data on the operation of the moving mechanism 250 while the nap box 10 is in use, and the like. The timer 56 mainly counts the execution time of the program PG.

[0039] [User Interface] As shown in Fig. 2, the UI 60 is communicatively connected to the control unit 50 via an I / O port. The UI 60 has a function of transmitting requests from the user U to the control unit 50. The UI 60 in this embodiment is in the form of either a touch panel or a voice dialogue, or a combination of these. Specific requests input to the UI 60 will be described later in the explanation of the operation of the nap box 10.

[0040] The above is a description of the configuration and functions of the nap box 10 of this embodiment.

[0041] <Nap Box Operation> Next, the operation of the nap box 10 of this embodiment will be described mainly with reference to Figures 3 and 4. Figure 3 is a flow diagram (algorithm of the program PG) showing the control flow of the nap box 10.

[0042] First, a user U who is using the sleeping box 10 opens the door 442 (see FIGS. 1A and 1B) of the housing 40, moves into the sleeping box 10, and closes the door 442. Then, the user U faces forward in the front-to-rear direction and places both feet on the fourth support portion 240. Next, when the user U operates the UI 60 to input his / her usage time (time to nap) into the UI 60, the UI 60 transmits the information to the control unit 50 (S10 in the control flow of FIG. 3). In response to this, the control unit 50 starts operating based on the program PG stored in the first storage unit 542. The transmitted usage time information is temporarily stored in the second storage unit 544. Next, the control unit 50 confirms via the UI 60 that the user U is standing in a fixed position. Specifically, the UI 60 inquires the user U by a screen (not shown) or voice, "Are you standing with both feet on the fourth support unit 240?", and when the user U inputs or speaks an affirmative answer (S20 in the control flow of FIG. 3), the control unit 50 starts the next operation (S30 in the control flow of FIG. 3) involving a judgment step. At this time, the UI 60 also transmits a suggestion to the user U to tilt the main body unit 234 of the third support unit 230 (see FIG. 1C) and place both arms and head on it. Here, the diagram shown in FIG. 4 as the initial state is a simplified diagram including the first support unit 210, the second support unit 220, and the third support unit 230 arranged in the positional relationship before the start of use. In S30, the control unit 50 first receives each measurement data from the multiple sensors 30 in the initial state, and determines whether the ratio of the load or pressure received from the body of the user U that each support part (first support part 210, second support part 220 and fourth support part 240) comes into contact with is within a predetermined ratio range. Here, the range of the predetermined ratio of the load or pressure received by each support portion is, for example, as shown in the following relational expression (hereinafter referred to as the relational expression of the predetermined ratio). First support part 210 : Second support part 220 : Fourth support part 240 = 45% or more but less than 55%: 25% or more but less than 35%: 15% or more but less than 25% (However, the total ratio of all supports is 100%) If the control unit 50 judges S30 to be positive, it performs the next operation (S40). On the other hand, if the control unit 50 judges S30 to be negative, it performs S32 without starting S40. In S32, the control unit 50 controls the first actuator 252 to raise the second support unit 220 by a set height (for example, 1 cm), and performs the judgment of S30 again. The subroutines of S30 and S32 are performed until the control unit 50 judges S30 to be positive (see adjustment state 1 and adjustment state 2 in FIG. 4). Here, information on the load or pressure received by each support part relative to the height of the second support part 220 is stored in the second storage part 544 every time a measurement is performed. If the control part 50 judges S30 in the entire movable range of the first actuator 252 by raising the height of the second support part 220 by 1 cm and the result is that a positive judgment is not made in S30, the control part 50 operates the first actuator 252 to move the second support part 220 to a height close to the relationship of the above-defined relational expression, and performs the subroutines S30 and S32 while moving the second support part 220 at a pitch shorter than 1 cm. This can be realized because the results of the subroutines S30 and S32 are stored in the second storage part 544 one after another. It should be noted that the adjustment of the vertical position of the third support portion 230 by the second actuator 254 is also performed, for example, in conjunction with the operation of S30. Next, in S40, the timer 56 is started to count. Next, in a judgment step S50, when the count number of the timer 56 reaches or exceeds the usage time stored in the second storage unit 544 (when the control unit 50 makes a positive judgment in S50), in S60 the UI 60 notifies the user U that the usage time has come. The notification in S60 is performed, for example, by a sound, by turning on a light in the housing 40 that was turned off during use, or the like. Next, when the user U wakes up from his nap and operates the UI 60 to understand that the usage time has elapsed, the control unit 50 controls the first actuator 252 to return the second support part 220 to the initial position (see Figure 4), thereby completing the operation of the nap box 10 of this embodiment.

[0043] The above is a description of the operation of the nap box 10 of this embodiment.

[0044] <Effects of the nap box> Next, the effects of the nap box 10 of this embodiment will be described.

[0045] [First effect] The support mechanism 20 of this embodiment moves the second support portion 220, which is one or two of the first support portion 210, the second support portion 220, and the fourth support portion 240, in the vertical direction relative to the one or the other of these (the first support portion 210 or the fourth support portion 240) (see Figure 4). Therefore, the support mechanism 20 and the nap box 10 of this embodiment can adjust the support position of each human body for each of a plurality of users U having different leg lengths.

[0046] [Second Effect] In the nap box 10 of this embodiment, sensors (first sensor 32, second sensor 34, third sensor 36) are arranged on each of the multiple support parts (first support part 210, second support part 220, and fourth support part 240) of the support mechanism 20, and each support part is configured to measure the load or pressure received from the body of the user U (see Fig. 1C and Fig. 2). Furthermore, in the nap box 10 of this embodiment, the control unit 50 operates the first actuator 252 while obtaining measurement data from each sensor (first sensor 32, second sensor 34, third sensor 36) based on the program PG, and adjusts the relative positional relationship of the multiple support parts (first support part 210, second support part 220, and fourth support part 240) so that the value of each sensor satisfies a relational expression of a predetermined ratio (see S30 and S32 in Fig. 3). Therefore, compared to an embodiment in which the load or pressure received from the human body is not measured by multiple sensors, the sleeping box 10 of this embodiment can appropriately adjust the support position of each human body according to multiple users U having different leg lengths. Accordingly, by using the program PG of this embodiment, the support position of the human body can be adjusted according to the different leg lengths of multiple users U.

[0047] [Third Effect] In the nap box 10 of this embodiment, the second support part 220, whose vertical height is adjusted by the first actuator 252, has a sheet 222 and a link mechanism 224 (see Figs. 1B and 1C). The sheet 222 is set so that the more it is moved upward by the first actuator 252, the wider the angle it forms with the link 224A so as to follow the vertical direction (see Fig. 4). With this configuration, the nap box 10 of this embodiment is arranged so that the height of the seat 222 is higher for users U with longer legs, and the inclination angle of the seat 222 is adjusted so that each support part (first support part 210, second support part 220 and fourth support part 240) makes appropriate surface contact with each user U even when used by multiple users U with different leg lengths. Therefore, in comparison with a configuration in which the inclination angle of the seat 222 cannot be adjusted, the nap box 10 of this embodiment can appropriately adjust the support position of each human body for each of multiple users U having different leg lengths.

[0048] The above is a description of the effects of the nap box 10 of this embodiment. The above is a description of the nap box 10 of this embodiment.

[0049] <<Variations>> Next, several modified examples (see Table 1 below) will be described. The changes in Table 1 refer to changes to the above-described embodiment. For each modified example, only the parts that are different from the above-described embodiment will be described.

[0050] [Table 1]

[0051] [First Modification] Changes: No multiple sensors The nap box 10 of the above-mentioned embodiment is configured such that sensors (first sensor 32, second sensor 34, third sensor 36) are arranged on each of the multiple support parts (first support part 210, second support part 220, and fourth support part 240) of the support mechanism 20, and the load or pressure received from the body of the user U at each support part can be measured (see Figures 1C and 2). However, a configuration in which some or all of these sensors are omitted (first modified example (not shown)) may also be used. In the case of this modification, the second effect of the above-mentioned embodiment is not achieved, but the first and third effects are achieved.

[0052] [Second Modification] Changes: The support part that the moving mechanism moves is different. In the nap box 10 of the above-described embodiment, the second support part 220 attached to the first actuator 252 of the moving mechanism 250 moves in the vertical direction, whereby the second support part 220 moves relative to the first support part 210 and the fourth support part 240 (see FIG. 4). However, as long as the moving mechanism 250 can, for example, move one or two of the first support portion 210, the second support portion 220, and the fourth support portion 240 in the vertical direction relative to the one or one other than the two of the first support portion, the second support portion, and the fourth support portion, the form (second modified example (not shown)) different from that of the above-described embodiment may be used. For example, in the second modified example, the first support 210, the second support 220, and the fourth support 240 may be attached to different moving mechanisms (not shown) so that they can move relative to each other. Also, for example, the second support 220 may be set so as not to move in the vertical direction, and the first support 210 and the fourth support 240 may be moved in the vertical direction together with the floor by a moving mechanism (not shown). Also, for example, the second support 220 and the fourth support 240 may be set so as not to move in the vertical direction, and the first support 210 may be moved in the vertical direction by the second actuator 254. Furthermore, in this case, the first support 210, which is composed of the base 212 and the cushion 214, may be configured to have a link mechanism added (a link mechanism is attached to the base 212 (not shown)) like the second support 220, so that the inclination angle of the first support is changed as the first support moves in the vertical direction. Even in the case of these second modified examples, the above-mentioned first and second effects or effects equivalent to these effects are achieved compared to the configuration in which the first support portion 210, the second support portion 220 and the fourth support portion 240 cannot move relative to each other.

[0053] [Third Modification] Changes: The structure of the third support is different. In the nap box 10 of the above-described embodiment, the third support part 230 is attached to the upper end of the second actuator 254 and can move within a preset range in the vertical direction in response to the operation of the second actuator 254 (see Figs. 1B and 1C). In this configuration, for example, the mechanism for moving the third support part 230 in the vertical direction may be manual. In addition, in the nap box 10 of the above-mentioned embodiment, the third support part 230 has an attachment part 232 attached to the second actuator 254, a main body part 234 that supports the human body from the front, and a hinge 236 (see FIG. 1E). However, it is sufficient that the third support section 230 can fulfill the function of supporting the human body from at least one side in the front-rear direction by contacting one or both of the upper limbs and head of the human body of the user U so that the upper limbs and head of the human body are positioned within a specified range in the front-rear direction. The third support section 230 may have a form (third modified example (not shown)) different from that of the above-mentioned embodiment as long as it is configured to fulfill that function. As a modified example of the third support section, it may be a string-like member or other member that supports one or both of the bases of both arms and the chin from the ceiling side or the rear side in the front-rear direction to prevent the upper body of the user U from falling over.

[0054] [Fourth Modification] Changes: The structure of the second support part is different (1) FIG. 5A is a schematic diagram for explaining the operation of a nap box 10A of the fourth modified example. In the nap box 10 of the above-described embodiment, the second support section 220 has a seat 222 and a link mechanism 224 (see Figs. 1B and 1C). The seat 222 is set to change its position so that the angle formed with the link 224A along the vertical direction increases as the seat 222 is moved upward by the first actuator 252 (see Fig. 4). However, the second support part may have a different configuration from that of the present embodiment as long as it is moved in the up-down direction by the moving mechanism 250. For example, as in the case of a nap box 10A of a fourth modified example shown in Fig. 5A, the second support part 220A may be composed of an axis body 220A1 arranged in a direction intersecting the up-down direction and the front-rear direction, and an elastic cylindrical member 220A2 covering the outer periphery of the axis body 220A1. In the case of the fourth variant, the posture of the second support part 220A does not change with movement in the vertical direction, but since the outer peripheral surface is a peripheral surface to begin with, it is advantageous in that it easily fits the body of users U with different leg lengths.

[0055] [Fifth Modification] Changes: The structure of the second support part is different (2) FIG. 5B is a schematic diagram of the main parts of a nap box 10B according to a fifth modified example. In the nap box 10 of the above-described embodiment, the second support section 220 has a seat 222 and a link mechanism 224 (see Figs. 1B and 1C). The seat 222 is set to change its position so that the angle formed with the link 224A along the vertical direction increases as the seat 222 is moved upward by the first actuator 252 (see Fig. 4). However, the second support part may have a different configuration from that of the present embodiment as long as it is moved in the up-down direction by the moving mechanism 250. For example, as in the case of the nap box 10B of the fifth modified example shown in Fig. 5B, the second support part 220B may be composed of an axis body 220B1 arranged along a direction intersecting the up-down direction and the front-rear direction, a cylindrical member 220B2 that covers the outer periphery of the axis body 220B1, a part of the outer periphery is a flat surface, and can be positioned by rotating around the axis body 220B1, and a cushion 220B3 attached to the flat surface. In the case of the fifth modified example, the posture of the second support part 220B does not change with the movement in the up and down direction, but the user U can adjust the inclination angle of the cushion 220B3 by changing the inclination angle of the cushion 220B3 by himself / herself. Therefore, this modified example is also effective in that it easily fits the body of the user U even if the user U has a different leg length.

[0056] [Sixth Modification] Changes: The notification method for when the usage time ends is different. FIG. 6 is a flow diagram showing a control flow of the nap box of the sixth modified example. In the operation of the nap box 10 in the above-described embodiment (see the control flow in FIG. 3), when the control unit 50 makes a positive determination in S50, the UI 60 notifies the user U in S60 that the time for use has come. The notification in S60 is performed, for example, by sound, or by turning on the lights in the housing 40 that were off during use. Therefore, in the case of the above-described embodiment, the UI 60 requires a component that generates sound (a speaker, as one example), etc. However, as long as the user U can be notified that the usage time has elapsed, the notification method may be a method different from that in the above-mentioned embodiment. For example, as in the control flow of the sixth modified example shown in FIG. 6, S60 in the above-mentioned embodiment (see the control flow of FIG. 3) may be replaced with S60A, and the control unit 50 may control the movement mechanism 250 so that the ratio of each measurement value of the plurality of sensors 30 that is within the range of the determined ratio becomes a ratio outside the range of the determined ratio. In this case, in order to notify the user U that the usage time has elapsed, the movement mechanism 250 may move, for example, the second support unit 220 up and down multiple times so that the relative positional relationship of the support units 220, 230, etc. becomes a positional relationship corresponding to within and outside the range of the determined ratio. By this operation, the user U who was napping is notified that the scheduled usage time has elapsed by the change in the posture of his / her body due to the change in the support position from each of the support parts 210, 220, etc. When the user U who has been notified inputs to the UI 60 that he / she agrees to end the operation, the control unit 50 returns each of the support parts 210, 220, etc. to their initial positions, and the operation of this modified example ends. Unlike the above-described embodiment, this modified example is effective in that notification can be realized by utilizing the support parts 210, 220 and the moving mechanism 250. In other words, according to this modified example, the moving mechanism 250, which more appropriately adjusts the support position of the human body, can be used to notify the user U of the passage of usage time through a physical sensation.

[0057] [Seventh Modification] Changes: The relative positions of the support parts change during use. FIG. 7 is a flow diagram showing a control flow of the nap box of the seventh modified example. In the operation of the nap box 10 in the embodiment described above (see the control flow in FIG. 3), the relative positions of the support parts 210, 220, etc. do not change during the period from when the user U starts to use the nap box 10 until when he or she finishes using the nap box 10. However, if the user U can take a nap or rest during the usage time, the relative positions of the support parts 210, 220, etc. may be changed during the usage time. Specifically, the control flow of the seventh modified example shown in Fig. 7 may be performed. The details of the control flow of the seventh modified example are as follows. In S30A, the moving mechanism 250 (the first actuator 252 thereof) is deliberately operated over a wide range, and the control unit 50 grasps a combination for the user U in which the ratio of the measurement values ​​of the multiple sensors 30 becomes a predetermined ratio. Information on this combination is temporarily stored in the second storage unit 544 of the storage device 54 (see FIG. 2). Next, in S40A, the control unit 50 operates the movement mechanism 250 to set each of the support units 210, 220, etc. within the range of the above combination, and starts the timer 56 to count. Next, in S50A and S52A, the control unit 50 changes the relative positions of each support part 210, 220, etc., using the moving mechanism 250, so that when 1 / 3 of the usage time has elapsed since the start of use, the relative positions of each support part 210, 220, etc. are different from those immediately before and become one of the combinations grasped in S30A. Next, in S54A and S56A, the control unit 50 changes the relative positions of each support part 220, 230, etc., using the moving mechanism 250, so that when 2 / 3 of the usage time has elapsed since the start of use, the relative positions of each support part 220, 230, etc. are different from those immediately before and become one of the combinations grasped in S30A. Next, in S58A, the control unit 50 changes the relative positions of the support units 210, 220, etc., by the movement mechanism 250 so that the relative positions of the support units 210, 220, etc. are different from the combination grasped in S30A when the start of use has elapsed. As a result, the user U who was napping is notified that the scheduled use time has elapsed because the posture of his / her body is changed due to the change in the support position from the support units 210, 220, etc. Then, when the user U inputs an agreement to end to the UI 60, the control unit 50 returns the support units 210, 220, etc. to their initial positions, and the operation of this modified example ends. In the case of this modified example, the relative positions of the supports 210, 220, etc. change during use in accordance with the combination grasped in S30A. Therefore, according to this modified example, it is possible to change the parts of the user U's body that receive reaction forces from the supports 210, 220, etc. during use. Therefore, according to this modified example, the areas where the reaction force is received by the user U's body from the support mechanism 20 during the period from the start of use to the elapse of usage time can be dispersed, compared to when the ratio of the measurement values ​​of the multiple sensors 30 remains constant. In this modified example, the relative positions of the support parts 210, 220, etc., are changed during the usage time by 1 / 3 and 2 / 3 of the usage time, but the changes may be made by integer fractions, such as 1 / 4 or 1 / 5 of the usage time, or the period until the changes may be shortened each time the usage time elapses.

[0058] [Eighth Modification] Changes: Mobile devices can be connected to the control unit (1) Fig. 8A is a block diagram of a control system CSA of a nap box of the eighth modified example, and Fig. 8B is a flow diagram showing a control flow of the nap box of this modified example. The nap box 10 of the above embodiment employs a configuration in which the user U transmits a request (such as the usage time) to the nap box 10 via the UI 60 (see FIG. 3). However, for example, a mobile device 70 (a mobile device 70 refers to a smartphone, a smart watch, a mobile phone, or other portable information terminal) owned by a user U may be connected to the control unit 50 of the nap box 10 using a wireless communication line such as WiFi or BLUETOOTH (registered trademark) (see the control system CSA of the eighth variant in Figure 8A). In this case, the mobile device 70 enables communication using dedicated application software for connecting to the nap box 10 as a user interface, and transmits a profile (body type information) relating to the user U's body type, such as height and weight, input via the application software. From another perspective, the control unit 50 receives the body type information and information on the usage time from the mobile device 70 (S10A in FIG. 8B). Next, the control unit 50 confirms via the UI 60 that the user U is standing at a fixed position (S20 in FIG. 8B), similarly to the case of S20 in the above-described embodiment (see FIG. 3). Next, the control unit 50 adjusts the relative positions of the support parts 210, 220, etc. corresponding to the user U stored in the program PG based on the received body type information by using the movement mechanism 250 (S30B in FIG. 8B). The subsequent control flow is performed in the same manner as in the above-described seventh modified example (see FIG. 7), as shown in FIG. 8B, for example. In this way, when the user U uses the device, it is possible to omit the adjustment of the relative positions of the support parts 210, 220, etc. using the moving mechanism 250 (see, for example, S30 and S32 in FIG. 3) that is performed in the initial operation of the above-mentioned embodiment. In this modified example, the control flow after S40A may be the control flow after S40 in the above-described embodiment (see FIGS. 3 and 6).

[0059] [Ninth Modification] Changes: Mobile devices can be connected to the control unit (2) FIG. 9 is a flow diagram showing a control flow of the nap box of the ninth modified example. This modification is a further modification of the eighth modification. In the eighth modification, S40A is performed after S30B (see FIG. 8B), but in this modification, the following steps are performed between S30B and S40A. Specifically, after S30B, in S70, the UI 60 asks the user U whether to fine-tune the relative positions of the supports 210, 220, etc. When the user U wants to fine-tune the automatically adjusted relative positions of the supports 210, 220, etc. (i.e., when the user U answers yes), the user U inputs that to the UI 60. Then, after the usage time has elapsed, the UI 60 asks the user U whether the support position was optimal, and when the user U answers that it is optimal, information relating the connected mobile device 70 to the optimal support position may be written, for example, to the first storage unit 542, the mobile device 70, or an external server 80 connected to the nap box 10 via the Internet (S62A). In this way, the optimal support position can be reproduced the next time the user U uses the nap box 10. In particular, if this information is written to the storage device of the mobile device 70 or the external server 80, it is effective in that the optimal support position can be reproduced even when using a nap box 10 that is available in another location.

[0060] [Tenth Modification] Changes: Mobile devices can be connected to the control unit (3) FIG. 10 is a flow diagram showing the control flow of the nap box of the tenth modified example. This modification is a further modification of the ninth modification. In the ninth modification, a subroutine (S50) for measuring the usage time is performed between S40 and S60A (see FIG. 9), but in this modification, if a negative determination is made in S50, the following steps are performed. Specifically, in S80, it is determined whether the heart rate is equal to or higher than a predetermined heart rate. If the mobile device 70 is, for example, a smart watch or the like that can measure the heart rate, this can be achieved by making the smart watch capable of communicating with the control unit 50. Here, the predetermined heart rate means the upper limit heart rate at which it is determined that the user U is napping (in a state of REM sleep). Then, if a positive determination is made in S80, that is, if it is determined that the user U is not napping, the relative positions of the support units 210, 220, etc. are adjusted in S82, that is, the support positions are finely adjusted. According to this modification, the support position can be adjusted more appropriately by using information from the mobile device 70 that can measure the heart rate.

[0061] [Eleventh Modification] Changes: User authentication in UI (1) FIG. 11 is a block diagram of a control system CSB of the nap box of the eleventh modified example. 11, in this modification, a UI 60A with a personal authentication function capable of personal authentication is adopted instead of the UI 60. Here, the personal authentication is, for example, authentication based on face authentication, fingerprint authentication, vocal cord authentication, or a combination of these. In this modification, when a user U uses the nap box for the second or subsequent time, information on the support position suitable for that user at the time of previous use is stored in storage device 54 or external server 80 together with the authentication information of that user U. Therefore, when this user U uses the nap box for the second or subsequent time, this information is retrieved from storage device 54 or external server 80 and used. According to this modification, when used for the second time or later, it is not necessary to adjust the support positions of the support parts 210, 220, etc., as in the case of the above embodiment (see FIG. 3).

[0062] [Twelfth Modification] Changes: User authentication in UI (2) In the above-mentioned eleventh modified example, a UI 60A with a personal authentication function is employed to identify the user U (see FIG. 11). However, for example, the UI 160A may not have a personal authentication function, and may simply register a management number or the like for identifying the user U, thereby enabling the UI 160A to be managed and used individually for multiple users U. In this modification, when a user U uses the nap box for the second or subsequent time, information on the holding position that suited the user at the time of previous use is stored in storage device 54 or external server 80 together with personal information of the user U. Therefore, when the user U uses the nap box for the second or subsequent time, this information is retrieved from storage device 54 or external server 80 and used. According to this modification, when using the device for the second or subsequent times, it is not necessary to adjust the support positions of the support parts 210, 220, etc., as in the case of the above-described embodiment (see FIG. 3). Furthermore, this modification is advantageous in that it is not necessary to provide the UI with a personal authentication function as in the eleventh modification (see FIG. 11), and it can be used without the mobile device 70 as in the eighth modification (see FIGS. 8A and 8B).

[0063] [Thirteenth Modification] Changes: Use AI technology Fig. 12A is a block diagram of the control system CSC of the nap box of the thirteenth modified example. Fig. 12B is a schematic diagram of the AI ​​model of this modified example. Fig. 12C is a flow diagram showing the control flow of the nap box of this modified example. In this modification, a model generating unit 58 is added to the control unit 50 (see FIG. 8A) of the control system CSA of the above-described eighth modification, and the control unit 50 is changed to a control unit 50A.

[0064] Hereinafter, the features of the AI ​​function in this modified example will be described with reference to FIG. 12B. (Teacher data) The training data in this modified example includes (1) the heights of multiple users U, each of whom has a different height (leg length), (2) the support posture of each user U when using the nap box (the relative positions of each support part 210, 220, etc.), and (3) information regarding the heart rate obtained by each user U from a mobile device 70 that can measure heart rate, such as a smart watch, which is the actual measured heart rate value after a certain time (for example, 5 minutes) has elapsed since the start of using the nap box. The actual height measurements are input to the UI 60 by each user U, uploaded from the mobile device 70, or obtained from a height gauge (for example, a non-contact ultrasonic type) attached to the sleeping box. This information is stored, for example, in the storage device 54 as training data. (Model generation part) The model generation unit 58 generates an estimation model by machine learning, estimating what supporting posture is optimal for a nap for a user U of a certain height, from the accumulated teacher data, i.e., data on the correlation between height, heart rate, and supporting posture. The program for generating the estimation model is stored in the first storage unit 542 as a program PGA in which an AI program including a program for generating the estimation model is added to a program PG for controlling the moving mechanism 250 (see FIG. 12A). (Control unit 50A (an example of a reception unit and a processing unit)) The control unit 50A receives the height and heart rate of the user U as input from the UI 60 or the mobile device 70. Then, the control unit 50A uses the above-mentioned estimation model to output the optimal supporting posture of the user U from the input received from the UI 60 or the mobile device 70. This concludes the description of the features of the AI ​​function of this modified example. An invention having the AI ​​characteristics of this modified example (for example, an estimation system) can be expressed as follows, as an example. ================================================================================ a model generation unit that generates an estimation model by machine learning to estimate the user's posture from the height and heart rate using the height, the user's posture for that height, and an actual measurement value of the heart rate obtained from the mobile device as training data; A reception unit that receives a user's height and heart rate as input; a processing unit that outputs a supporting posture of a user from the input received by the receiving unit, using the estimation model; An estimation system comprising: ================================================================================

[0065] Next, the operation of the nap box of this modified example will be described with reference to FIG. 12C. The initial steps, S10A and S20, are similar to those in the eighth modified example (see FIG. 8) and the ninth modified example (see FIG. 9). Next, in S30, the relative positions of the support parts 210, 220, etc. are adjusted by the moving mechanism 250 based on, for example, the body type information received from the mobile device 70. In this case, in this modified example, a learned model (estimated model) derived by the above-mentioned AI function is used. Here, in the above-mentioned estimated model, the input is the height and heart rate of the user U, but in this step, the input is the height and the heart rate corresponding to REM sleep (i.e., a heart rate that has not actually been measured). As a result, an optimal supporting posture (relative positions of the support parts 210, 220, etc.) for the user U of that height is derived as an output. Based on this result, the control unit 50A operates the moving mechanism 250. Next, in S40, the timer 56 starts counting. Next, in S70, the UI 60 asks the user U whether the user U is using the mobile device 70 and whether the heart rate can be measured if the user U is using the mobile device 70. When the user U inputs an affirmative result to the UI 60, the UI 60 transmits the result to the control unit 50A. Thereafter, in S74A, the control unit 50A starts recording the heart rate while communicating with the mobile device 70 and continues counting the usage time (see S50). The heart rate data transmitted from the mobile device 70 is stored in the storage device 54. The recorded result is used by the model generation unit 58 as new teacher data to update the estimation model. On the other hand, if the user U inputs a negative result (that is, that the mobile device 70 capable of measuring the heart rate is not being used) into the UI 60 in S70, the usage time continues to be counted (see S50). Then, when the usage time has elapsed, S60A is performed and the operation of this modified example ends. The above is a description of the operation of this modified example.

[0066] According to this modification, when used for the second time or later, it is not necessary to adjust the support positions of the support parts 210, 220, etc., as in the case of the above embodiment (see FIG. 3). In addition, the nap box operating in this modified example may be the nap box 10 of the previously described embodiment, and it is also effective in that a more appropriate support posture can be output in cases where support parts other than the second support part 220, such as the first support part 210 and the third support part 230, are capable of changing the vertical position and inclination angle (not shown).

[0067] The above is a description of several modified examples.
