[0001] The present invention relates to a nap seat. [Background technology]

[0002] A lighting control system that periodically changes the brightness of lighting fixtures to regulate breathing and relax people, thereby contributing to comfortable sleep and waking up, has been known for some time (see, for example, Patent Document 1). In this system, when waking a person up, the brightness of the room is automatically gradually increased. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-339993 Summary of the Invention [Problem to be solved by the invention]

[0004] By the way, the so-called power nap is known, which is a method of improving brain performance by taking a short nap during the day. However, it is desirable for such a power nap to be able to prompt awakening in a short time without causing discomfort, and there is still room for improvement in the method for achieving this.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a nap seat that can prompt a user to wake up in a short time without causing discomfort to the user. [Means for solving the problem]

[0006] In order to achieve the above object, the nap seat according to claim 1 of the present invention supports the buttocks and thighs of a user. In addition, the seat is tilted so that the buttocks are positioned lower than the thighs when viewed from the side in the seat width direction. The seat supports the upper body including the head of the user. At the same time, the seat is tilted so that the head is positioned higher than the buttocks when viewed from the side in the seat width direction. An upper body support section and a lower leg support section for supporting the user In addition, the seat is tilted so that the feet are positioned lower than the thighs when viewed from the side in the seat width direction.a head-side frame disposed on the upper body support side of the seat body when the seat body is in the comfortable position and covers the top and both sides of the head of the user when the seat body is in the comfortable position and in the supine position with the seat body in the comfortable position; and an illumination device disposed on both side walls of the head-side frame that covers the both sides of the head of the user when the seat body is in the comfortable position and illuminates the amount of light required to wake the user toward both sides of the head only in the seat width direction. hand There are.

[0007] According to the invention described in claim 1, The seat, upper body support, and lower leg support are arranged in an inclined position like a chair. The seat body is placed in a comfortable position, and the light necessary for awakening is emitted from the illumination devices on both sides of the head frame, which cover both sides of the head of the user lying on their back. The illumination devices are installed on both sides of the head frame, and the light is emitted only from the width direction of the seat, to both sides of the head. 。 Therefore, compared to when the amount of light required to wake up is irradiated from above the head of a user lying on their back, the user feels less glare. This allows the user to wake up in a short time without feeling uncomfortable. In other words, the nap sheet of the present invention can help the user wake up in a short time without causing discomfort.

[0008] A nap seat according to a second aspect of the present invention is the nap seat according to the first aspect, wherein the head-side frame is opaque.

[0009] According to the invention described in claim 2, the head-side frame that covers the upper and both sides of the head of the user lying on their back is made opaque, which prevents light emitted from the illumination device from leaking outside the nap seat.

[0010] The nap seat according to claim 3 is the nap seat according to claim 1 or claim 2, wherein the seat body is 、 Chair posture in which the user is seated of It is configured to be accessible.

[0011] According to the invention of claim 3, the seat body is configured to allow the user to lie in a comfortable position on their back. Not only that, Chair posture with the user in a seated position of Therefore, compared to when the seat body can only take the comfortable position with the user lying on their back, it is easier for an awake user to get off the seat body by putting the seat body in the chair position.

[0012] The nap sheet according to claim 4 is Claim 1~ Claim 3 Any one of the following In the nap seat described above, the irradiation device is positioned above the upper body support portion when the seat body is in a comfortable position.

[0013] According to the invention of claim 4, the irradiation device is disposed above the upper body support portion when the seat body is in the comfortable position. Therefore, light is irradiated more efficiently to both sides of the user's head than when a part of the irradiation device is disposed below the upper body support portion when the seat body is in the comfortable position (where a part of the irradiation device is hidden by the upper body support portion).

[0014] The nap sheet according to claim 5 is also 4 The nap seat described in the above, wherein the illumination device has a rectangular window portion that transmits light, and the window portion is arranged parallel to the upper body support portion when the seat body is in a comfortable position in a side view from the seat width direction.

[0015] According to the invention of claim 5, when the seat body is in a comfortable position, the upper body support portion and the rectangular window portion through which light from the irradiation device passes are arranged parallel to each other in a side view from the seat width direction. Therefore, compared to when the window portion of the irradiation device is arranged horizontally, the area of ​​the window portion that is hidden by the upper body support portion is reduced, and light is efficiently irradiated to both sides of the user's head. Note that "parallel" in this invention also includes "approximately parallel" which is slightly deviated from exact parallel. [Effects of the Invention]

[Figure 3] 1 is a schematic side view showing a nap seat according to the present embodiment together with a user. DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. For ease of explanation, the arrows FR, UP, and RH shown in each drawing indicate the front, upper, and right sides of the seat body 12 constituting the nap seat 10, respectively. Therefore, in the following description, when the front-rear, up-down, and left-right directions are mentioned without special mention, they refer to the front and rear in the front-rear direction, the up-down direction, and the left and right in the seat width direction.

[0019] As shown in Figures 1 and 3, the nap seat 10 of this embodiment is composed of a seat body 12, a head-side frame 14 that mainly covers the head of user P (see Figure 3), a foot-side frame 16 that mainly covers the feet of user P, a curtain 18 provided between the head-side frame 14 and the foot-side frame 16, and a rotation mechanism 22 (see Figure 3) that changes the position of the seat body 12 between a seated position and a supine position.

[0020] (seat body) The seat body 12 supports the user P in a seated position and in a supine position, and is configured to include a seat portion 12A, an upper body support portion 12B, and a lower leg support portion 12C. The seat portion 12A, the upper body support portion 12B, and the lower leg support portion 12C are integrally covered with a cover, and the seat body 12 is configured as an integrated seat in which the seat portion 12A, the upper body support portion 12B, and the lower leg support portion 12C are continuous.

[0021] 3, the seat 12A includes a seat frame 26 that forms the framework of the seat 12A, and a cushion material 27 that covers the seat frame 26 and supports the user, and is configured to be able to support from below the buttocks and thighs of the user P. The seat 12A is slightly tilted so that the rear end is positioned lower than the front end in a side view seen from the seat width direction (left-right direction).

[0022] Upper body support part 12B is connected to the rear end (one end) of seat part 12A so as to be rotatable about an axial direction that is the seat width direction. Upper body support part 12B includes an upper frame 28 that forms the skeleton of upper body support part 12B, and a cushion material 29 (not shown) that covers upper frame 28 to support the user, and is configured to be able to support the upper body, including the head, of user P from below. Upper body support part 12B is arranged at an angle so that its rear end is located higher than its front end, which is connected to seat part 12A, in a side view.

[0023] A crus support section 12C is connected to the front end (other end) of the seat section 12A so as to be rotatable about an axis that is the seat width direction. The crus support section 12C includes a lower frame 30 that forms the skeleton of the crus support section 12C, and a cushion material 31 (not shown) that covers the lower frame 30 and supports the user, and is configured to be able to support the lower legs of the user P from below. The crus support section 12C is tilted so that its front end is positioned lower than its rear end, which is connected to the seat section 12A, in a side view.

[0024] The seat body 12 is configured to be deformable by a rotation mechanism 22 so that it can assume a chair position (chair shape) in which the user P is seated, and a comfortable position (bed shape) in which the user P is lying on his back. Fig. 1 shows the seat body 12 in the chair shape (chair position), and Fig. 3 shows the seat body 12 in the bed shape (comfortable position).

[0025] (Rotation mechanism) 3, the rotation mechanism 22 in this embodiment includes, for example, an upper motor 32 for rotating the upper body support part 12B relative to the seat part 12A, an upper cylinder 34, and an upper link 36. The rotation mechanism 22 also includes a lower motor 38 and a lower cylinder 40 for rotating the lower leg support part 12C relative to the seat part 12A.

[0026] The upper motor 32 is composed of a motor such as a stepping motor or servo motor attached to the underside of the seat 12A, and is driven by power supplied from a power source (not shown) to generate rotational force. The upper cylinder 34 is composed of a case 34A and a rod 34B that moves in and out of the case 34A, and is configured so that the rotational motion of the upper motor 32 is converted into linear motion, causing the rod 34B to protrude or retract relative to the case 34A.

[0027] An upper link 36 is connected to the tip of the rod 34B. The upper link 36 is formed in an elongated shape, and one end of the upper link 36 is rotatably connected to the tip of the rod 34B. The other end of the upper link 36 is rotatably connected to the upper frame 28 via an upper bracket 44. An elongated hole 36A that penetrates in the seat width direction is formed between the one end and the other end of the upper link 36, and a shaft 37 that extends in the seat width direction is inserted into this elongated hole 36A.

[0028] A lower motor 38 is disposed in front of the upper motor 32. The lower motor 38 is composed of a motor such as a stepping motor or servo motor attached to the underside of the seat 12A, and is driven by power supplied from a power source (not shown) to generate rotational force. The lower cylinder 40 includes a case 40A and a rod 40B that extends and retracts relative to the case 40A. The rotational motion of the lower motor 38 is converted into linear motion, causing the rod 40B to extend or retract relative to the case 40A.

[0029] The tip of the rod 40B is rotatably connected to a lower bracket 42 attached to the lower surface of the lower frame 30. A long hole 42A penetrating the lower bracket 42 in the seat width direction is formed, and the tip of the rod 40B is configured to be movable along this long hole 42A.

[0030] When the seat body 12 assumes the bed shape, the upper motor 32 is driven to retract the rod 34B of the upper cylinder 34 into the case 34A, as shown in Figure 3. As the rod 34B retracts, the upper link 36 moves forward along the shaft 37 and rotates clockwise around the shaft 37. This causes the upper link 36 to lean backward, and the upper body support part 12B assumes a bed shape with the upper body support part 12B reclining at a predetermined angle relative to the seat part 12A.

[0031] Meanwhile, the lower motor 38 is driven to protrude the rod 40B of the lower cylinder 40 from inside the case 40A. This causes the tip of the rod 34B to move along the elongated hole 42A, and the lower surface of the lower frame 30 moves in a direction away from the lower surface of the seat frame 26. This results in a bed shape in which the angle between the seat 12A and the lower leg support 12C is wider than a predetermined angle.

[0032] In the nap seat 10 according to this embodiment, even when the seat body 12 is in the bed shape, the seat portion 12A and the upper body support portion 12B do not lie flat, but the upper body support portion 12B is tilted slightly upward relative to the seat portion 12A. The seat portion 12A and the lower leg support portion 12C do not lie flat, but the lower leg support portion 12C is tilted slightly downward relative to the seat portion 12A. In other words, the bed shape has an inclined arrangement similar to that of a chair shape.

[0033] When the seat body 12 assumes the chair shape, the opposite occurs. That is, the rod 34B of the upper cylinder 34 protrudes from inside the case 34A, and the rod 40B of the lower cylinder 40 retracts into the case 40A. As a result, the upper link 36 is raised, the upper body support portion 12B is raised at a predetermined angle relative to the seat portion 12A, and the lower surface of the lower leg support portion 12C is pulled toward the lower surface of the seat portion 12A, resulting in a chair shape in which the lower frame 30 extends downward from the front end of the seat frame 26.

[0034] In this way, the seat body 12 can be transformed into a chair shape and a bed shape by the rotation mechanism 22. However, the seat body 12 is not limited to this transformation; by controlling the upper motor 32 and the lower motor 38, the seat body 12 can also be transformed into any shape between the bed shape shown in Fig. 3 and the chair shape shown in Fig. 1.

[0035] (Head side frame) 1, the head-side frame 14 is disposed at the end of the seat body 12 on the upper body support part 12B side, and is formed in a generally cylindrical shape with both the front and rear sides open. The head-side frame 14 is also formed in a generally elliptical shape that is long in the vertical direction when viewed from the front-to-rear direction, and the lower end of the head-side frame 14 is fixed to a connecting plate 17, which will be described later.

[0036] The head-side frame 14 is opaque so as not to transmit light emitted from an illumination device 50 (described later), and its inner surface is configured to reflect light. A support base 20 that houses part of a rotation mechanism 22 is provided on the lower inside of the head-side frame 14, and the seat body 12 is supported on this support base 20.

[0037] Additionally, the rear opening of the head-side frame 14 is closed by a rear cloth material 24. The rear cloth material 24 is made of a stretchable cloth material and is attached to the periphery of the head-side frame 14. The rear cloth material 24 is, for example, made of a cloth material that reflects part of the light. This makes it difficult to see the inside of the nap sheet 10 from the outside, but allows the inside of the nap sheet 10 (user P) to see what is happening on the outside.

[0038] A rear rail 14A is provided along the periphery of the front opening of the head-side frame 14. The rear rail 14A is provided along the periphery of the upper opening of the head-side frame 14 and is arranged in a generally inverted "U" shape when viewed from the front-to-rear direction. One end of a curtain 18, which will be described later, is attached to the rear rail 14A.

[0039] Here, the head-side frame 14 is inclined so that its upper portion is positioned further rearward than its lower portion (see FIG. 3). The head-side frame 14 is designed to cover the entire head (at least continuously from above and both sides) of the user P who is supported in a supine position on the bed-shaped seat main body 12. Note that when the seat main body 12 is in the chair shape, the head-side frame 14 is designed to cover part of the head of the user P seated on the seat main body 12 from the surroundings.

[0040] (Foot side frame) 1, the foot-side frame 16 is disposed at the end of the seat body 12 on the side of the lower leg support 12C, and is formed in a generally cylindrical shape with both the front and rear sides open. Similar to the head-side frame 14, the foot-side frame 16 is formed in a generally elliptical shape that is long in the vertical direction when viewed from the front-to-rear direction, and the lower end of the foot-side frame 16 is fixed to a connecting plate 17.

[0041] As shown in Figures 1 and 3, the connecting plate 17 is formed in a roughly rectangular flat plate shape with the longitudinal direction being the fore-and-aft direction of the seat, and the lower end of the head-side frame 14 is fixed to the rear end of the connecting plate 17, and the lower end of the foot-side frame 16 is fixed to the front end of the connecting plate 17.

[0042] The front opening of the foot-side frame 16 is closed by a front cloth material 25. The front cloth material 25 is made of a stretchable cloth material and is attached to the periphery of the foot-side frame 16. The front cloth material 25 is made of a cloth material that reflects part of the light, for example. This makes it difficult to see the inside of the napping sheet 10 from the outside, but allows the inside of the napping sheet 10 (user P) to see what is happening on the outside.

[0043] A front rail 16A is provided along the periphery of the rear opening of the foot-side frame 16. The front rail 16A is provided along the periphery of the upper opening of the foot-side frame 16 and is arranged in a generally inverted "U" shape when viewed from the front-to-rear direction. The other end of the curtain 18, which will be described later, is attached to this front rail 16A.

[0044] Here, foot-side frame 16 is inclined so that its upper portion is positioned further rearward than its lower portion (see FIG. 3). Foot-side frame 16 is designed to cover the entire periphery (at least continuously from above and both sides) of the feet of user P who is supported in a supine position on bed-shaped seat body 12. The positions of the front end of seat body 12 and foot-side frame 16 are set so that the toes of user P do not come into contact with front cloth material 25 when seat body 12 is transformed into the bed shape.

[0045] (curtain) 1, curtain 18 is made of fabric and is hung between head-side frame 14 and foot-side frame 16. That is, the rear end of curtain 18 is attached to rear rail 14A provided on head-side frame 14, and the front end of curtain 18 is attached to front rail 16A provided on foot-side frame 16.

[0046] Curtain 18 moves along front rail 16A and rear rail 14A, and can take a closed position that covers the upper part of seat main body 12, and an open position that opens the upper part of seat main body 12. Note that Fig. 1 shows a state in which curtain 18 has moved to the open position.

[0047] Furthermore, because the curtain 18 is made of a material that allows some of the external light to pass through, some of the external light passes through the curtain 18 and enters the inside of the nap sheet 10. Therefore, even when the curtain 18 is in the closed position and covers the user P from above, the area around the user P is not completely dark.

[0048] Furthermore, this nap seat 10 is designed so that even when the curtain 18 is in the closed position, the lower side of the seat body 12 is exposed, allowing light to enter the seat from the left and right below the seat body 12. This allows people outside to see through the gap below the curtain 18 that user P is using the seat.

[0049] Additionally, head-side frame 14 is formed to be longer in the vertical direction than foot-side frame 16. Therefore, in the closed position, curtain 18 extends diagonally downward from head-side frame 14 toward foot-side frame 16. In other words, head-side frame 14, foot-side frame 16, and curtain 18 form nap seat 10 in the shape of a tunnel whose diameter narrows from the head side to the foot side.

[0050] (irradiation device) 1 to 3, illumination devices 50 are provided at predetermined positions (near the head of user P) on the right side wall 14R and the left side wall 14L of the head-side frame 14 that covers both sides of the head of user P. The illumination devices 50 are configured to be able to irradiate both sides of the head of user P with the amount of light required for awakening.

[0051] More specifically, the irradiation device 50 includes a substantially rectangular box-shaped case 46 that is fixed by fixing means such as screws to the inner surfaces of the right side wall 14R and the left side wall 14L of the head-side frame 14. A high-intensity light source (not shown) that is powered from the outside is provided inside the case 46, and a substantially rectangular window 48 that transmits light irradiated from the high-intensity light source is formed on the inner wall surface of the case 46 in the seat width direction.

[0052] Here, to wake up comfortably from a nap, it is generally necessary to be exposed to light with an illuminance of 2500 lux or more for about one minute (preferably one minute or more). In other words, even if the user P, who is supported in a supine position on the seat main body 12, has his or her eyes closed, the light stimulates the suprachiasmatic nucleus of the user P. For this reason, the high-intensity light source provided in this irradiation device 50 is configured to be able to irradiate light with an illuminance of 2500 lux or more from the window portion 48.

[0053] 3, the irradiation device 50 (at least the window portion 48) is disposed at a predetermined position above the upper body support portion 12B of the seat main body 12 when the user P takes a comfortable position in side view (when the seat main body is in a bed shape) and as close as possible to the upper body support portion 12B. The irradiation device 50 is disposed so as to be approximately parallel to the upper body support portion 12B of the seat main body 12 (the angle of the upper body of the user P) when the user P takes a comfortable position in side view.

[0054] That is, the irradiation device 50 is fixed at a predetermined position on the inner surface of the right side wall 14R and the left side wall 14L of the head-side frame 14 so that, in a side view, the upper and lower (particularly the lower) edge portions 46A of the case 46 of the irradiation device 50 and the upper and lower (particularly the lower) edge portions 48A of the window portion 48 (see FIG. 2) are inclined along the upper body support portion 12B, respectively.

[0055] (action) Next, the operation of the nap seat 10 according to this embodiment configured as described above will be described.

[0056] As shown in Fig. 3, user P can take a nap on nap seat 10. At this time, even if seat body 12 is in a bed shape (comfortable posture), seat portion 12A, upper body support portion 12B, and lower leg support portion 12C are transformed into the bed shape while remaining in the same inclined position as in a chair shape, so user P can take a nap while lying on his back (with his face facing in one direction, upward).

[0057] On the other hand, when waking up a user P who is napping with the seat body 12 in a comfortable position, at the specified timing for waking up, the high-brightness light source of the illumination device 50 provided on the right side wall 14R and left side wall 14L (near the head of the user P) of the head side frame 14 is turned on by a timer or the like, and the amount of light required for waking up the user P (2500 lux or more, for example, an illuminance of 3000 lux) is illuminated from the window portion 48 onto both sides of the user P's head for one minute or more.

[0058] Here, since the user P is napping while lying on his / her back in a narrow space enclosed by the head-side frame 14 that is roughly arc-shaped when viewed from the front, the light emitted from the illumination device 50 is reliably irradiated from close range to both sides of the head of the user P. Therefore, compared to when light is irradiated from above the head of the user P napping while lying on his / her back, the suprachiasmatic nucleus of the user P can be effectively stimulated without causing discomfort due to glare to the user P, and the user P can be urged to wake up in a short time.

[0059] That is, if light emitted from a high-intensity light source is irradiated from above a user P who is lying on his / her back, the user P will feel discomfort due to the glare. However, the illumination device 50 according to this embodiment irradiates light only to both sides of the head of the user P who is lying on his / her back, and therefore can suppress or prevent the user P who is napping and maintaining the lying-on-his-back position from feeling the glare (feeling uncomfortable), and the napping user P can wake up in a short time.

[0060] Moreover, because the inner surface of the head-side frame 14 is configured to be light-reflecting, even if only a pair of illumination devices 50 are provided (even if there are only a few light sources), the space can be illuminated relatively brightly by utilizing the reflection from the inner surface of the head-side frame 14. Furthermore, because the head-side frame 14 is opaque and does not allow light to pass through, it is possible to suppress or prevent light emitted from the illumination devices 50 from leaking outside the napping sheet 10.

[0061] Furthermore, the irradiation device 50 is disposed on the inner surfaces of the right side wall 14R and the left side wall 14L of the head-side frame 14 at a predetermined position that is higher than the upper body support part 12B of the seat main body 12 when the user P assumes a comfortable posture in a side view, and that is as close as possible to the upper body support part 12B. Therefore, compared to a case where, for example, the lower part (part) of the window part 48 of the irradiation device 50 is disposed lower than the upper body support part 12B (is hidden by the upper body support part 12B), it is possible to efficiently irradiate light onto both sides of the head of the user P.

[0062] Furthermore, the irradiation device 50 is arranged so as to be approximately parallel to the upper body support part 12B of the seat main body 12 when the user P assumes a comfortable position in a side view (the edge part 46A of the case 46 and the edge part 48A of the window part 48 are arranged in an inclined position along the upper body support part 12B). Therefore, compared to when the window part 48 (edge ​​part 48A) of the irradiation device 50 is arranged in the horizontal direction, for example, the area of ​​the window part 48 that is hidden by the upper body support part 12B can be reduced, and light can be more efficiently irradiated to both sides of the head of the user P.

[0063] Furthermore, the seat body 12 is configured to be able to assume a comfortable position in which the user P lies on their back, and a chair position in which the user P is seated. Therefore, compared to when the seat body 12 can only assume the comfortable position in which the user P lies on their back, the user P who wakes up from a nap can easily get off the seat body 12 by putting the seat body 12 in the chair position.

[0064] While the nap sheet 10 according to this embodiment has been described above with reference to the drawings, the nap sheet 10 according to this embodiment is not limited to the one shown in the drawings and can be modified as appropriate within the scope of the gist of the present invention. For example, the shapes of the case 46 and window 48 of the irradiation device 50 are not limited to the generally rectangular shapes shown in the drawings.

[0065] Furthermore, the seat body 12, head-side frame 14, foot-side frame 16, and curtain 18 may each be formed in a different shape. For example, the foot-side frame 16 and the head-side frame 14 may be formed to have the same length in the up-down direction. Furthermore, the curtain 18 may be configured to open and close automatically, and may be made of metal or resin.

[0066] Furthermore, the curtain 18 may be configured to be stored inside the foot-side frame 16, and to be able to cover the head-side frame 14 by the user P by pulling it out from the foot-side frame 16. In this case, it is preferable to provide a hook (not shown) or the like at the downstream end of the curtain 18 in the pulling-out direction, and to provide a latching portion (not shown) on the head-side frame 14 that can latch onto the hook when the curtain 18 is closed.
