[0008] A pillow 1 according to an embodiment will be described with reference to the drawings. In the following description, the directions of the pillow 1 are defined as the shoulder width direction and the height direction based on the user when using the pillow 1. In addition, the head side of the user in the height direction is sometimes referred to as the head side of the pillow 1, and the shoulder side of the user, i.e., the foot side, is sometimes referred to as the shoulder side of the pillow 1. As shown in Figs. 1 to 8, the pillow 1 according to the embodiment is configured with a head member 10 and a neck and shoulder member 20. The head member 10 and the neck and shoulder member 20 are each configured with different members. Being configured with different members means that the pillow 1 is configured by combining members that are physically separated from each other at least when the pillow 1 is manufactured.

[0009] In this embodiment, the head member 10 and the neck / shoulder member 20 are connected to each other so as to be separable from each other, for example, by hook-and-loop fasteners or buttons. The head member 10 and the neck / shoulder member 20 may be configured to be inseparable from each other by sewing or bonding. The head member 10 and the neck / shoulder member 20 may not be connected to each other, and may simply be arranged side by side when in use.

[0010] The head member 10 and the neck / shoulder member 20 can each be used alone. That is, the head member 10 and the neck / shoulder member 20 can be omitted. The head member 10 and the neck / shoulder member 20 can also be referred to as the first member 10 and the second member 20, respectively.

[0011] The head member 10 is a member that comes into contact with the head 91 of the user 90 during use. That is, the head member 10 is a member on which the head 91 of the user 90 is placed and supports the head 91 of the user 90 during use, as shown in FIG.

[0012] The neck and shoulder member 20 is a member that comes into contact with the neck 92 and shoulders 93 of the user 90 when in use. That is, as shown in Fig. 1, the neck and shoulder member 20 supports the neck 92 of the user 90 when in use, and comes into contact with the shoulders 93 of the user 90 in a manner that wraps around them.

[0013] The neck and shoulder member 20 is set to have a longer dimension in the user's shoulder width direction than the head member 10. Also, the neck and shoulder member 20 is set to have a shorter dimension in the user's height direction than the head member 10. As shown in Fig. 6, when the pillow 1 is viewed from the side in the width direction, the area of ​​the neck and shoulder member 20 is larger than that of the head member 10. Also, when the pillow 1 is cut at the center in the shoulder width direction, as shown in Fig. 7, when the cross-sectional area is viewed, the cross-sectional area of ​​the neck and shoulder member 20 is larger than that of the head member 10.

[0014] As shown in FIG. 4 and other figures, the neck and shoulder member 20 has a recessed portion 201 and a bulging portion 202. The recessed portion 201 is provided in the center of the neck and shoulder member 20 in the shoulder width direction, i.e., at a position straddling the center. As shown in FIG. 7, the recessed portion 201 is formed in a shape that is recessed downward in the region of the neck and shoulder member 20 opposite the head member 10, i.e., on the user's shoulder 93 side. The recessed portion 201 is recessed along the shape of the neck 92 of the user 90. This allows the neck and shoulder member 20 to firmly encase and hold the neck 92 of the user 90 placed on the neck and shoulder member 20 with the recessed portion 201.

[0015] 1 and other figures, the bulging portion 202 is formed in a shape that bulges slightly toward the opposite side from the head member 10, that is, toward the shoulder side in the height direction, at a position that straddles the center of the neck and shoulder member 20 in the shoulder width direction. The bulging portion 202 is a portion that comes into contact with the vicinity of the base of the shoulder of the user 90. In other words, when the neck and shoulder member 20 is viewed in a planar direction, the bulging portion 202 located in the center in the shoulder width direction at the edge on the shoulder side bulges slightly, and both sides in the shoulder width direction are formed in a shape that continues smoothly curved from the bulging portion 202.

[0016] The head member 10 and the neck / shoulder member 20 are covered by covers 11 and 21, respectively. The cover 11 that encases the head member 10 and the cover 21 that encases the neck / shoulder member 20 may be made of different materials or may be made of the same material.

[0017] The head member 10 and the neck and shoulder member 20 are made of different materials. In this embodiment, the neck and shoulder member 20 is made of a material having a higher resilience than the head member 10. In this case, the resilience of the neck and shoulder member 20 is set to 15% or more, and preferably 50% or more. In contrast, the resilience of the head member 10 is set to be smaller than the resilience of the neck and shoulder member 20 and less than 50%, and preferably less than 15%. In this embodiment, the resilience of the neck and shoulder member 20 is set to, for example, 50% or more. In contrast, the resilience of the head member 10 is set to be less than 15%.

[0018] The head member 10 may be made of, for example, low-resilience fiber, as shown in Fig. 9. The low-resilience fiber may be made of, for example, woven polyethylene fiber. Since the low-resilience fiber has a small resilience, it can deform along the head 91, which is a relatively heavy part of the human body, and can hold the head 91 by enveloping it. In contrast, the neck and shoulder member 20 may be made of, for example, high-resilience urethane, as shown in Fig. 10. Since the high-resilience urethane has a large resilience, it can firmly hold the neck 92 and shoulders 93 of the user 90.

[0019] 10 and 11, the pillow 1 is provided with an adjustment member 22. The adjustment member 22 is made of, for example, nylon, polyester, or cotton, and is configured in a sheet shape that conforms to the bottom surface of the neck and shoulder member 20 and has a thickness of about several mm to several tens of mm. The adjustment member 22 has a function of adjusting the height of the neck and shoulder member 20 by arranging one or more adjustment members on the bottom surface side of the neck and shoulder member 20, or by removing the adjustment member 22. The adjustment member 22 is stored in the cover 21 together with the neck and shoulder member 20.

[0020] 1 and 10, the pillow 1 is provided with a neck heater 31 and a shoulder heater 32. The neck heater 31 and the shoulder heater 32 can also be referred to as a first heater 31 and a second heater 32, respectively. The pillow 1 can also be provided with heaters other than the neck heater 31 and the shoulder heater 32.

[0021] The neck heater 31 and the shoulder heater 32 are heaters that operate upon receiving electric power. For the neck heater 31 and the shoulder heater 32, various heaters that generate heat upon receiving electric power, such as Nichrome wire heaters and PTC heaters, can be used. The neck heater 31 and the shoulder heater 32 are formed in the form of a flexible film, attached to the surface of the neck and shoulder member 20, and housed in the cover 21 together with the neck and shoulder member 20.

[0022] As shown in Figs. 1 and 10, the neck heater 31 is provided on the neck and shoulder member 20 on the head 91 side of the user 90. The shoulder heater 32 is provided on the neck and shoulder member 20 on the shoulder 93 side of the user 90. That is, the neck heater 31 is provided closer to the head member 10 than the shoulder heater 32. The neck heater 31 and the shoulder heater 32 are both configured in a rectangular shape that is long in the shoulder width direction of the user 90. The shoulder heater 32 is set to have a longer dimension in the shoulder width direction of the user than the neck heater 31. That is, the dimension in the shoulder width direction of the shoulder heater 32 is longer than the dimension in the shoulder width direction of the neck heater 31. The neck heater 31 and the shoulder heater 32 may each be configured by combining a plurality of heaters.

[0023] The neck heater 31 is provided at a position where it can warm the neck 92 of the user 90 when in use. When the neck heater 31 is supplied with power, that is, when the switch is turned on and operates, it generates heat and warms the neck 92 of the user 90. The shoulder heater 32 is provided at a position where it can warm the shoulders 93 of the user 90 when in use. When the shoulder heater 32 is supplied with power, that is, when the switch is turned on and operates, it generates heat and warms the shoulders 93 of the user 90. Note that the neck heater 31 and the shoulder heater 32 may be configured to warm not only the neck 92 and shoulders 93, respectively, but also parts other than the neck 92 and shoulders 93, for example, parts near the neck 92 and shoulders 93, such as the back of the head and ears.

[0024] The neck heater 31 and the shoulder heater 32 are configured to be able to operate independently of each other. That is, the neck heater 31 and the shoulder heater 32 can be arbitrarily switched among four states: a state in which both the neck heater 31 and the shoulder heater 32 are off, a state in which both the neck heater 31 and the shoulder heater 32 are on, a state in which the neck heater 31 is on and the shoulder heater 32 is off, and a state in which the neck heater 31 is off and the shoulder heater 32 is on. In this embodiment, the state in which the heaters 31 and 32 are on means a state in which the heaters 31 and 32 are energized and generate heat. In addition, the state in which the heaters 31 and 32 are off means a state in which the heaters 31 and 32 are not energized and do not generate heat.

[0025] 1 and 12, the pillow 1 further includes a vibration unit 40. The vibration unit 40 receives power and vibrates. That is, when the vibration unit 40 receives power, that is, when the vibration unit 40 operates by being switched on, the vibration unit 40 vibrates the neck / shoulder member 20 by its own vibration. As a result, the vibration unit 40 provides a massage effect to the neck 92 and shoulders 93 of the user 90 that are in contact with the neck / shoulder member 20.

[0026] The vibration unit 40 is provided at the center of the neck and shoulder member 20 in the longitudinal direction, i.e., the shoulder width direction, and is embedded inside the neck and shoulder member 20 as shown in FIG. 12. In this case, the neck and shoulder member 20 is formed with an embedding hole 203 for embedding the vibration unit 40 in the neck and shoulder member 20. After the vibration unit 40 is embedded, a cover member 23 made of sponge or the like is embedded in the embedding hole 203 as shown in FIG. 13. As a result, the embedding hole 203 is closed by the cover member 23. The vibration unit 40 is configured to be operable independently of the neck heater 31 and the shoulder heater 32. In other words, the user can operate the vibration unit 40 regardless of the operating status of the neck heater 31 and the shoulder heater 32.

[0027] 14 to 16, the pillow 1 further includes a controller 50 and a board 60. The controller 50 is provided outside the head member 10 and the neck and shoulder member 20. One side of the controller 50 is electrically connected in advance to the neck heater 31, the shoulder heater 32, and the vibration unit 40 via the board 60. The other side of the controller 50 is connected to an external power source such as a household outlet or a mobile battery by a user's operation. The controller 50 has a function of controlling the power supply from an external power source to the neck heater 31, the shoulder heater 32 and the vibration unit 40.

[0028] In this embodiment, the controller 50 has a function of independently turning on and off the power supply to the neck heater 31, the shoulder heater 32, and the vibration unit 40. The controller 50 can set and control the temperatures of the neck heater 31 and the shoulder heater 32 based on the user's operation. Furthermore, the controller 50 can set and control the on timer and off timer of the neck heater 31, the shoulder heater 32, and the vibration unit 40 based on the user's operation. The on timer is a function of turning on the neck heater 31, the shoulder heater 32, and the vibration unit 40 based on the lapse of a set time. The off timer is a function of turning off the neck heater 31, the shoulder heater 32, and the vibration unit 40 based on the lapse of a set time.

[0029] The board 60 electrically connects the neck heater 31, the shoulder heater 32, and the vibration section 40 to the controller 50. As shown in Fig. 15, the board 60 is made of a printed circuit board having a side of, for example, several mm to several tens of mm, and is embedded in the neck and shoulder member 20. For example, as shown in Fig. 15, a board storage section 204 is formed on the side surface of one end in the shoulder width direction of the neck and shoulder member 20. The board 60 is inserted into this board storage section 204. As a result, the board 60 is embedded in one end of the neck and shoulder member 20 in the shoulder width direction.

[0030] In this case, the ground line that determines the reference potential between the neck heater 31, the shoulder heater 32, and the vibration unit 40 is connected from the controller 50 to the substrate 60 by a single external ground line 71. The substrate 60 branches the ground line into a neck heater internal ground line 811 that is electrically connected to the neck heater 31, a shoulder heater internal ground line 812 that is electrically connected to the shoulder heater 32, and a vibration unit internal ground line 813 that is electrically connected to the vibration unit 40.

[0031] That is, the controller 50 and the board 60 are connected by an external ground wire 71, a neck heater external signal wire 72, a neck heater external power wire 73, a shoulder heater external signal wire 74, a shoulder heater external power wire 75, and a vibration section external power wire 76. The external ground wire 71, the neck heater external signal wire 72, the neck heater external power wire 73, the shoulder heater external signal wire 74, the shoulder heater external power wire 75, and the vibration section external power wire 76 are bundled together and configured as a single wiring as a whole, as shown in FIG.

[0032] The external ground line 71 defines the reference potential of the neck heater 31, the shoulder heater 32, and the vibration unit 40. The neck heater external signal line 72 passes a control signal for the neck heater 31 transmitted from the controller 50. The neck heater external power line 73 passes driving power for the neck heater 31 supplied from an external power source via the controller 50. The shoulder heater external signal line 74 passes a control signal for the shoulder heater 32 transmitted from the controller 50. The shoulder heater external power line 75 passes driving power for the shoulder heater 32 supplied from an external power source via the controller 50. And the vibration unit external power line 76 passes driving power for the vibration unit 40 supplied from an external power source via the controller 50.

[0033] The substrate 60 and the neck heater 31 are electrically connected by a neck heater internal ground wire 811, a neck heater internal signal wire 82, and a neck heater internal power wire 83. The substrate 60 and the shoulder heater 32 are electrically connected by a shoulder heater internal ground wire 812, a shoulder heater internal signal wire 84, and a shoulder heater internal power wire 85. The substrate 60 and the vibration section 40 are electrically connected to the vibration section 40 by a vibration section internal ground wire 813 and a vibration section internal power wire 86. The wires 811 to 813 and 82 to 86 are stored in a wiring storage section 205 formed in a groove shape in the neck / shoulder member 20.

[0034] The external ground wire 71 is electrically connected to each of the neck heater internal ground wire 811, the shoulder heater internal ground wire 812, and the vibration section internal ground wire 813 via the first printed wiring 61 provided on the substrate 60. In other words, the external ground wire 71 is branched by the first printed wiring 61 on the substrate 60 and electrically connected to the neck heater internal ground wire 811, the shoulder heater internal ground wire 812, and the vibration section internal ground wire 813.

[0035] Furthermore, the neck heater external signal line 72 is electrically connected to the neck heater internal signal line 82 via the second printed wiring 62. The neck heater external power line 73 is electrically connected to the neck heater internal power line 83 via the third printed wiring 63. The shoulder heater external signal line 74 is electrically connected to the shoulder heater internal signal line 84 via the fourth printed wiring 64. The shoulder heater external power line 75 is electrically connected to the shoulder heater internal power line 85 via the fifth printed wiring 65. And the vibration section external power line 76 is electrically connected to the vibration section internal power line 86 via the sixth printed wiring 66.

[0036] According to the embodiment described above, the pillow 1 includes the head member 10, the neck and shoulder member 20, the neck heater 31, and the shoulder heater 32. The head member 10 is a member that contacts the head 91 of the user 90 when used. The neck and shoulder member 20 is set to have a longer dimension in the shoulder width direction of the user than the head member 10, and is a member that contacts the neck 92 and shoulders 93 of the user 90 when used. The neck heater 31 is a heater provided in the neck and shoulder member 20, which operates by receiving electric power, and has a function of warming the neck 92 of the user 90 when used. The shoulder heater 32 is a heater provided in the neck and shoulder member 20, which operates by receiving electric power, and has a function of warming the shoulders 93 of the user 90 when used. The neck heater 31 and the shoulder heater 32 are configured to be able to operate independently of each other.

[0037] According to this, the pillow 1 supports the head 91 of the user 90 with the head member 10, and supports the neck 92 of the user 90 with the neck and shoulder member 20. Therefore, compared to a general pillow that supports the head 91 and neck 92 with one member, the pillow 1 can support the body of the user 90 more appropriately. In addition, the pillow 1 is provided with a neck heater 31 and a shoulder heater 32. According to this, by warming the neck 92 and shoulders 93 of the user 90, muscle tension can be relieved and a relaxing effect can be achieved. In addition, since an artery runs through the back of the neck, by warming the area around the artery, the warmed blood circulates throughout the body, and the effect of warming the body can be expected, especially in cold winters.

[0038] Furthermore, the neck heater 31 and the shoulder heater 32 are configured to be able to operate independently of each other. This allows the user 90 to warm only either the neck 92 or the shoulders 93, or to warm both. This allows the user 90 to warm the neck 92 and shoulders 93 according to his / her physical condition and preference, which provides a higher relaxation effect and, as a result, improves comfort regarding sleep.

[0039] The neck heater 31 is provided closer to the head member 10 than the shoulder heater 32. The shoulder heater 32 is set to have a longer dimension in the shoulder width direction of the user 90 than the neck heater 31. Since the neck heater 31 is provided closer to the head member 10 than the shoulder heater 32, heat can be effectively supplied to the neck 92 of the user 90. This is particularly beneficial for users who are particularly susceptible to getting cold around the neck 92 or who have stiffness or tension concentrated in their neck.

[0040] Furthermore, since the shoulder heater 32 is configured to be longer in the shoulder width direction of the user 90 than the neck heater 31, heat can be supplied evenly to the entire shoulders 93 of the user 90. This makes it possible to more effectively relieve stiffness and ease tension, particularly for users who have stiffness or muscle tension over a wide area of ​​the shoulders. Furthermore, sleep quality can be more effectively improved.

[0041] Here, important muscles and nerves pass through the neck 92 and shoulders 93, so if pressure is applied to the neck 92 and shoulders 93 for a long period of time, it is likely to cause stiff neck or muscle pain. Therefore, the neck and shoulder member 20 is made of a material with a higher resilience modulus than the head member 10. Specifically, the head member 10 is made of low-resilience fiber. Moreover, the neck and shoulder member 20 is made of high-resilience urethane.

[0042] According to this, firstly, the head member 10 is more likely to flexibly deform along the body of the user 90, in this case, along the head 91, than the neck and shoulder member 20. Therefore, it is easier to flexibly fit the shape of the head 91, which differs for each user 90. This improves the feeling of holding the head 91, making it easier to maintain comfort. And because the head member 10 is more likely to flexibly fit the shape of the head 91, it is expected to have the effect of helping relieve tension during sleep. As a result, the user 90 can achieve a more relaxed sleep.

[0043] In other words, the neck and shoulder member 20 is made of a material with a higher resilience than the head member 10. This prevents the neck and shoulder member 20 from sinking due to the weight of the head 91 and neck 92, and can firmly support the neck 92 and shoulders 93 of the user 90. This allows the position of the neck 92 and shoulders 93 of the user 90 to be properly maintained, and excessive pressure on the neck 92 and shoulders 93 to be avoided. As a result, the pillow 1 of this embodiment can simultaneously achieve a good fit for the head 91 of the user 90 and firm support for the neck 92 and shoulders 93, and as a result, the comfort of sleep can be further improved.

[0044] The neck and shoulder member 20 further has a recessed portion 201. The recessed portion 201 is formed in a recessed shape on the opposite side to the head member 10 at a position straddling the center of the neck and shoulder member 20 in the shoulder width direction. With this, when using the pillow 1, the area around the neck 92 of the user 90 fits into the recessed portion 201, providing a better fit.

[0045] The neck and shoulder member 20 also has a bulging portion 202. The bulging portion 202 is formed in a shape bulging out toward the opposite side to the head member 10 at a position straddling the center of the neck and shoulder member 20 in the shoulder width direction. As a result, when the neck and shoulder member 20 is viewed in a planar direction, the bulging portion 202 located in the center in the shoulder width direction at the edge on the shoulder side bulges slightly, and both sides in the shoulder width direction are formed in a shape that is smoothly curved continuously from the bulging portion 202. This allows the neck and shoulder member 20 to fit the neck 92 and shoulders 93 of the user 90 more satisfactorily, and as a result, more comfortable sleep can be provided.

[0046] The pillow 1 further includes a vibration unit 40. The vibration unit 40 is provided on the neck and shoulder member 20, and vibrates upon receiving electric power. This allows a massage effect to be provided to the user 90 by the vibration of the vibration unit 40. The combination of the thermal effect of the neck heater 31 and shoulder heater 32 and the massage effect of the vibration unit 40 helps to more effectively relieve tension in the neck 92 and shoulders 93 of the user 90, and as a result, the user 90 can sleep in a more relaxed state.

[0047] The pillow 1 further includes a controller 50 and a substrate 60. The controller 50 is provided outside the head member 10 and the neck and shoulder member 20. The controller 50 is connected to an external power source and is electrically connected to the neck heater 31, the shoulder heater 32, and the vibration unit 40. The controller 50 controls the power supply from the external power source to the neck heater 31, the shoulder heater 32, and the vibration unit 40.

[0048] The substrate 60 is embedded in the neck / shoulder member 20. The ground line that determines the reference potential of the neck heater 31, the shoulder heater 32, and the vibration unit 40 is connected from the controller 50 to the substrate 60 by a single external ground line 71, and is branched by the substrate 60 into a neck heater internal ground line 811 connected to the neck heater 31, a shoulder heater internal ground line 812 connected to the shoulder heater 32, and a vibration unit internal ground line 813 connected to the vibration unit 40.

[0049] This reduces the number of wires drawn out from the neck and shoulder member 20, i.e., makes it possible to reduce the thickness of the bundle of wires drawn out from the neck and shoulder member 20, compared to the case where a ground wire is connected from the controller 50 to each of the neck heater 31, the shoulder heater 32, and the vibration section 40. As a result, the wires drawn out from the neck and shoulder member 20 to the controller 50 can be made flexible, improving the ease of handling of the controller 50.

[0050] Although the present disclosure has been described based on the embodiment, it is understood that the present disclosure is not limited to the embodiment or structure. The present disclosure also includes various modifications and modifications within the equivalent range.
