[0018] A pillow 1 according to an embodiment of the present invention will be described below with reference to the drawings. For ease of understanding, mutually orthogonal XYZ coordinates are set and referred to as appropriate. The Z-axis direction of the XYZ coordinates is the height direction of the pillow 1, as shown in Figs. 1(A) and (B). The +Y direction is the depth direction of the pillow 1, and the -Y direction is the front direction of the pillow 1. The X-axis direction is the width direction of the pillow 1.

[0019] 2(A) and (B), the pillow 1 is used by being placed on a placement surface B1, which is, for example, the upper surface of a bed B or a futon. The pillow 1 is used by a user U lying on his / her back or side and sleeping with his / her head U1 placed on the pillow 1. This pillow 1 includes a holding member 10, a pillow base 20, a body pressure dispersion member 30, a flexible member 40, and a pillow cover 50, as shown in Figs. 3A to 3C and 4.

[0020] The holding member 10 is disposed on the lower side (-Z side) of the pillow base 20. As shown in FIG. 5, the holding member 10 is used to hold the pillow base 20 in a state inclined at an inclination angle θ with respect to the placement surface B1 of the bed B. Thus, the holding member 10 functions as a body adjuster that holds the proper posture of the user U. In detail, the holding member 10 is formed in a plate shape having a lower surface 10a that contacts the placement surface B1 of the bed B and an upper surface 10b that contacts the pillow base 20 and is inclined with respect to the lower surface 10a. In this embodiment, the inclination angle θ is in the range of 5° to 25°. Preferably, the inclination angle θ is 15°. When the inclination angle θ is 15°, the user U can sleep in a state in which the airway is not blocked and the thorax is open, making it easy to breathe through the nose. However, the inclination angle θ is not limited to 15°. The inclination angle θ is set to an appropriate angle as appropriate according to the body type and preferences of the user U.

[0021] The holding member 10 is made of a highly resilient material so that it does not deform too much even when the weight of the user U is applied to it. Specifically, the holding member 10 is made of, for example, urethane foam, which is a foam made by foaming polyurethane resin. However, the material is not limited to this. The holding member 10 may be made of a material other than urethane foam. As shown in FIG. 4, the holding member 10 has a plurality of ventilation holes 12 that open in the plate thickness direction and enhance breathability.

[0022] As shown in FIG. 5, the holding member 10 is formed with a shoulder support portion 11. As shown in FIG.

[0023] The shoulder support portion 11 supports the shoulders U3 of the user U.

[0024] As shown in Figs. 5 and 6, the pillow base 20 is a member that receives and supports the weight of a part of the body including the head U1 of the user U. In this embodiment, as shown in Fig. 7, the pillow base 20 is integrally formed with the pillow cover 50. Also, as shown in Fig. 8, eight storage chambers 21a, 21b, 21c, 21d, 21e, and 21f are formed in the pillow base 20. These storage chambers 21a to 21f store any one of the resilient fillers B-1, B-2, B-3, and B-4. Although it is preferable to fill each of the multiple storage chambers 21a to 21f with different fillers B-1, B-2, B-3, and B-4 whose resilience is suitable for the support location, the fillers B-1, B-2, B-3, and B-4 may be filled with the same resilience.

[0025] As shown in FIG. 9(A), the filler B-1 is, for example, a transparent bead formed into a cylindrical shape with a diameter of 5 mm. The filler B-1 is made of raw materials recycled from waste materials such as the stems and leaves of plants such as corn and sugar cane. The filler B-1 is highly breathable and flexibly deforms when the user's body pressure is applied, so that it fits the user's body shape. However, the material of the filler B-1 is not limited to this. The filler B-1 may be made of materials other than the above-mentioned raw materials.

[0026] As shown in FIG. 9(B), the filler B-2 is, for example, a white bead formed into a cylindrical shape with a diameter of 5 mm, and is softer than the filler B-1. Like the filler B-1, the filler B-2 is made of raw materials recycled from waste materials such as the stems and leaves of plants such as corn and sugar cane. The filler B-2 is highly breathable and flexibly deforms when the user's body pressure is applied, so that it fits the user's body shape. However, the material of the filler B-2 is not limited to this. The filler B-2 may be made of a material other than the above-mentioned raw materials.

[0027] As shown in FIG. 9(C), the filler B-3 is, for example, colored beads formed into a cylindrical shape with a diameter of 5 mm. The filler B-3 is made of raw materials recycled from, for example, old rice that is not suitable for consumption, crushed rice produced by rice cracker manufacturers, etc. The filler B-3 is highly breathable, and when the user's body pressure is applied, it deforms while having high resilience, and fits the user's body shape. However, the material of the filler B-3 is not limited to this. The filler B-3 may be made of a material other than the above-mentioned raw materials.

[0028] As shown in Fig. 9(D), the filler B-4 is small granular cotton with a diameter of about 3 to 5 mm. However, the material of the filler B-4 is not limited to this.

[0029] As shown in Fig. 8 and Fig. 10, the storage chamber 21a is a storage chamber for a headrest portion that supports the user's head. The storage chamber 21a is filled with any one of fillers B-1, B-2, B-3, and B-4. For example, the storage chamber 21a stores filler B-2, which is white beads. However, the present invention is not limited to this, and the storage chamber 21a may store something other than filler B-2, which is white beads.

[0030] The storage chamber 21b is provided adjacent to the storage chamber 21a for the headrest portion near the front (-Y side). This storage chamber 21b is a storage chamber for the neck rest portion that supports a part of the neck of the user. Specifically, the storage chamber 21b supports the user's cervical vertebrae from the base to the fifth cervical vertebra. This storage chamber 21b is filled with any of the fillers B-1, B-2, B-3, and B-4. For example, the storage chamber 21b contains the filler B-2, which is a white bead. However, this is not limited to this, and the storage chamber 21b may contain something other than the filler B-2, which is a white bead.

[0031] The storage chamber 21c is a storage chamber for the head top portion, which is provided adjacent to the rear (+Y side) of the storage chamber 21a for the headrest portion. Any of fillers B-1, B-2, B-3, and B-4 is filled in the storage chamber 21c. For example, the storage chamber 21c contains filler B-3, which is colored beads. However, the present invention is not limited to this, and the storage chamber 21c may contain something other than filler B-3, which is colored beads.

[0032] As shown in Figs. 8, 11 and 12, two storage chambers 21d are provided adjacent to both sides of the storage chamber 21a for the headrest portion in the width direction (X direction). The storage chamber 21d is also provided adjacent to the storage chamber 21c for the headtop portion. This storage chamber 21d is a storage chamber for the face rest portion that supports the face of the user who turns over in either the +X direction or the -X direction. This storage chamber 21d is filled with any of the fillers B-1, B-2, B-3 and B-4. For example, the storage chamber 21d contains the filler B-3, which is colored beads. However, this is not limited to this, and the storage chamber 21d may contain something other than the filler B-3, which is colored beads.

[0033] Two accommodation chambers 21e are provided adjacent to both sides of the accommodation chamber 21b for the neck rest part in the width direction (X direction). In addition, the accommodation chamber 21e is also provided adjacent to the accommodation chamber 21d for the face rest part. This accommodation chamber 21e is a accommodation chamber for the face lift part that supports a part of the body including the chin of the user who turns over in either the +X direction or the -X direction. This accommodation chamber 21e is filled with any of the fillers B-1, B-2, B-3, and B-4. For example, the accommodation chamber 21e contains the filler B-1, which is a transparent bead. However, this is not limited to this, and the accommodation chamber 21e may contain something other than the filler B-1, which is a transparent bead.

[0034] As shown in Figs. 8 and 10, the storage chamber 21f is provided adjacent to the storage chamber 21b for the neck rest part nearer to the front (-Y side). This storage chamber 21f is a storage chamber for the neck pad part that supports the neck lower part U2a (see Fig. 5), which is a part of the neck of the user. Specifically, the storage chamber 21f supports the fifth to seventh cervical vertebrae of the user. By the storage chamber 21f supporting the neck lower part U2a (see Fig. 5), the storage chamber 21f, together with the storage chamber 21b for the neck rest part, can fill the gap along the curved cervical vertebrae of the user and support the entire neck. This storage chamber 21f is filled with any of the fillers B-1, B-2, B-3, and B-4. For example, the storage chamber 21f contains the filler B-4, which is cotton. However, the present invention is not limited to this, and the storage chamber 21f may contain a filler other than the filler B-4, which is cotton.

[0035] 13, an opening 22 through which the filling material can be put in and taken out is formed on the back surface of the pillow base 20 in the storage chambers 21a to 21f. A fastener is provided in the opening 22 for closing the storage chambers 21a to 21f after the filling material is put in the storage chambers 21a to 21f.

[0036] The pillow base 20 thus constructed is recessed in the portion of its upper surface (the surface on the +Z side) where the head and neck are placed, as shown in Figures 3B, 3C and 6, in order to improve the user's sleeping comfort.

[0037] As shown in Fig. 3B, Fig. 3C and Fig. 6, the body pressure dispersing member 30 is disposed on the upper side (+Z side) of the pillow base 20, spanning the multiple accommodation chambers 21a to 21f. The body pressure dispersing member 30 is formed from an elastic material capable of absorbing and dispersing the user's body pressure applied to its upper surface 30a. Specifically, the body pressure dispersing member 30 is made from an expandable foam material. Furthermore, the body pressure dispersing member 30 has gaps formed by uneven processing on its upper surface 30a in order to further improve the effect of dispersing the user's body pressure.

[0038] 6, the flexible member 40 is a member that covers the upper side (+Z side) of the body pressure dispersion member 30, thereby reducing the feel of the filling materials B-1, B-2, B-3, and B-4 to the user U. Specifically, the flexible member 40 is a member that reduces discomfort caused by the sensation of the hardness of the filling materials B-1, B-2, B-3, and B-4 to the user U. The flexible member 40 is made of a soft material in order to reduce the feel of the filling materials B-1, B-2, B-3, and B-4.

[0039] In this embodiment, as shown in FIG. 7, the flexible member 40 is integrally formed with the pillow cover 50. Also, as shown in FIG. 14, seven storage chambers 41a, 41b, 41c, 41d, and 41e are formed in the flexible member 40. These storage chambers 41a to 41e store small granular cotton pieces having a diameter of, for example, about 3 to 5 mm. The use of such cotton pieces improves the sleeping comfort of the user. However, this is not limited to this. The storage chambers 41a to 41e may store something other than small granular cotton pieces having a diameter of about 3 to 5 mm.

[0040] As shown in FIG. 14, the accommodation chamber 41a is a chamber for accommodating a headrest portion that supports the user's head.

[0041] The accommodation chamber 41b is a chamber for accommodating the neck rest portion, which is provided adjacent to the front side (-Y side) of the accommodation chamber 41a for the head rest portion.

[0042] The accommodation chamber 41c is a chamber for accommodating the head top portion, which is provided adjacent to the rear (+Y side) of the accommodation chamber 41a for the headrest portion.

[0043] Two accommodation chambers 41d are provided adjacent to each other on both sides of the width direction (X direction) of the accommodation chamber 41a for the headrest portion. In addition, the accommodation chamber 41d is also provided adjacent to the accommodation chamber 41c for the headrest portion. This accommodation chamber 41d is a accommodation chamber for the face rest portion that supports the face of the user who turns over in either the +X direction or the -X direction.

[0044] Two accommodation chambers 41e are provided adjacent to each other on both sides in the width direction (X direction) of the accommodation chamber 41b for the neck rest part. In addition, the accommodation chamber 41e is also provided adjacent to the accommodation chamber 41d for the face rest part. This accommodation chamber 41e is a accommodation chamber for the face lift part that supports a part of the body including the chin of the user who turns over in either the +X direction or the -X direction.

[0045] 7, the storage chambers 41a to 41e have openings 42 formed on the back surface of the flexible member 40, through which cotton can be inserted and removed. Unlike the storage chambers 21a to 21f, the openings 42 formed in the storage chambers 41a to 41e do not have zippers for closing the openings after inserting the cotton. However, this is not limiting. The openings 42 may have zippers.

[0046] As shown in FIG. 3B and FIG. 7, the pillow cover 50 houses the holding member 10, the pillow base 20, the body pressure dispersion member 30, and the flexible member 40. Thus, the pillow 1 has a structure for housing the pillow base 20 and the body pressure dispersion member 30. In this embodiment, the pillow cover 50 is formed with a holding member housing section 51 for housing the holding member 10. The pillow base 20 and the flexible member 40 are connected to the holding member housing section 51, so that the pillow base 20 and the flexible member 40 are integrally formed with the pillow cover 50. The pillow cover 50 is made of a material with good breathability. In order to improve the comfort of the user, the pillow cover 50 is formed with a recess in the portion where the head and neck are placed, similar to the upper surface of the pillow base 20, on the upper surface (+Z side surface) thereof. Furthermore, a pillow cover that covers the whole or part of the pillow cover 50 may be attached to the pillow 1 according to the user's preference.

[0047] The pillow 1 configured as above is divided into a plurality of parts with different functions in a plan view as shown in Fig. 15. Specifically, the pillow 1 is formed with the following parts: a head rest part 1a, a neck rest part 1b, a head top part 1c, a face rest part 1d, a face lift part 1e, a neck pad part 1f, and a shoulder support part 1g.

[0048] The face rest portion 1d supports the head U1 of the user U who turns over in either the +X direction or the -X direction.

[0049] The facelift portion 1e supports a part of the body, including the chin, of the user U who turns over in either the +X direction or the -X direction.

[0050] The shoulder support portion 1g supports the shoulders U3 of the user U, as shown in FIG. 2(B).

[0051] As described above, the pillow 1 according to this embodiment includes a pillow base 20 in which a plurality of storage chambers 21a-21f are formed to store resilient fillers B-1-B-4, as well as a body pressure dispersion member 30 that distributes the user's body pressure and improves the sensory feel of use, as shown in Fig. 6. Therefore, in this embodiment, by sealing the fillers B-1-B-4 in accordance with the volume of the storage chambers 21a-21f created to match the user's body type, the shape of the pillow 1 itself has the function of creating a high personal fit obtained by following the lines of the user's body, while obtaining the effect of dispersing body pressure, which leads to improved sensory feel of use. As a result, the user of the pillow 1 can get a good night's sleep.

[0052] Furthermore, in the pillow 1 according to this embodiment, the body pressure dispersion member 30 has an upper surface 30a provided with irregularities for dispersing the body pressure of the user. Therefore, in this embodiment, the effect of dispersing the body pressure of the user can be further improved. As a result, the user of the pillow 1 can get a good night's sleep.

[0053] The applicant conducted an experiment to confirm the effect of dispersing body pressure using the pillow 1 according to the present embodiment and a pillow according to a comparative example shown in FIG. 16. As shown in FIG. 16(A), the pillow according to the comparative example is rectangular in shape with a recess formed in the center in a plan view. Also, as shown in FIG. 16(B), a cylindrical filler made of polypropylene is contained inside the pillow according to the comparative example. Unlike the pillow according to the present embodiment, the pillow according to the comparative example contains only one type of filler. Therefore, the pillow according to the comparative example does not have a plurality of storage chambers for containing the filler. Also, unlike the pillow according to the present embodiment, the pillow according to the comparative example does not include a body pressure dispersing member or a retaining member.

[0054] FIG. 17 shows the measurement results of body pressure distribution using the pillow 1 according to the present embodiment and the pillow according to the comparative example. Specifically, the stress distribution diagram on the left side of FIG. 17 shows the body pressure distribution in the pillow according to the comparative example. The stress distribution diagram on the right side of FIG. 17 shows the body pressure distribution in the pillow 1 according to the present embodiment. And FIG. 17 shows the result of measurement performed in a supine (back) state using the pillow 1 according to the present embodiment and the pillow according to the comparative example, with a sheet-shaped body pressure distribution sensor (body pressure measuring device) laid on the pillow placed on a coil mattress with a thickness of 20 cm. As can be seen from FIG. 17, the pillow 1 according to the present embodiment shows that the body pressure is sufficiently distributed over the entire area from the head to the neck, shoulders to the shoulders. From the result, it can be seen that the body pressure is sufficiently distributed so that a large load is not applied to a specific part, and the subject using the pillow 1 is likely to have a good sleep because the sensory feeling of use is improved.

[0055] Moreover, as shown in FIG. 18, the pillow 1 according to this embodiment includes a holding member 10 that holds the pillow base 20 in an inclined state. The holding member 10 is inclined so that its upper surface 10b becomes higher from the front (-Y side) of the pillow 1 toward the back (+Y side). This inclination allows the user U of the pillow 1 to get a good night's sleep. In particular, in this embodiment, the inclination angle θ is 15°, so the user U can sleep with his / her airway not blocked and with his / her thorax open, making it easy to breathe through his / her nose. As a result, the user U of the pillow 1 can get a good night's sleep.

[0056] Furthermore, in the pillow 1 according to this embodiment, by replacing the holding member 10 with another holding member 10-2 having a different inclination angle θ2, the inclination angle can be changed according to the body type and preferences of the user U of the pillow 1. As a result, the user U of the pillow 1 can get a good night's sleep.

[0057] In this embodiment, as shown in Fig. 5, the holding member 10 is formed with a shoulder support portion 11. Therefore, as shown in Fig. 15, the pillow 1 can support the shoulders U3 as well as the head U1 and neck U2 of the user U. This allows the pillow 1 to improve the sleeping comfort of the user U. As a result, the user U of the pillow 1 can get a good night's sleep.

[0058] As shown in FIG. 6, the pillow 1 according to this embodiment further includes a flexible member 40 in addition to the pillow base 20 and the body pressure dispersion member 30. The flexible member 40 is made of a soft material that reduces the feel of the filling materials B-1, B-2, B-3, and B-4 on the user. Therefore, in this embodiment, by selecting the type of filling materials B-1 to B-4 to be stored in the storage chambers 21a to 21f, it is possible to obtain the effect of reducing the feel of the filling materials B-1, B-2, B-3, and B-4 on the user while having the function of being able to match the user's body type. As a result, the user of the pillow 1 can get a good night's sleep.

[0059] In addition, as shown in Fig. 8, the pillow base 20 of the pillow 1 according to this embodiment has a neck pad storage chamber 21f formed adjacent to the front (-Y side) of the neck rest storage chamber 21b. The neck pad storage chamber 21f fills the gaps along the fifth to seventh cervical vertebrae where gaps are likely to occur when the pillow is in use, and together with the neck rest storage chamber 21b, the neck of the user can be supported by the entire neck. This provides the effect of dispersing the user's body pressure over the entire neck. As a result, the user of the pillow 1 can get a good night's sleep.

[0060] In addition, the pillow base 20 of the pillow 1 according to this embodiment is formed with a pair of accommodation chambers 21d for face rest parts and a pair of accommodation chambers 21e for face lift parts. The accommodation chambers 21d for the face rest parts and the accommodation chambers 21e for the face lift parts can support the face and neck of the user who turns over in the width direction (X direction). This provides the effect of dispersing the user's body pressure not only when the user is sleeping on his / her back, but also when the user turns over. As a result, the user of the pillow 1 can get a good night's sleep.

[0061] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

[0062] For example, in the pillow 1 according to the present embodiment, as shown in Fig. 6, the holding member 10, the pillow base 20, the body pressure dispersion member 30, and the flexible member 40 are laminated in this order from the bottom. However, this is not limited to this. For example, any of the holding member 10, the pillow base 20, the body pressure dispersion member 30, and the flexible member 40 may be omitted. For example, if it is not necessary to incline the pillow base 20 according to the body type or preference of the user of the pillow 1, the holding member 10 may be omitted.

[0063] Furthermore, in the pillow 1 according to the embodiment, the upper surface 30a of the body pressure dispersing member 30 is provided with unevenness. However, this is not limited to this. The upper surface 30a of the body pressure dispersing member 30 does not have to be provided with unevenness. For example, the upper surface 30a of the body pressure dispersing member 30 may be a flat surface. However, from the viewpoint of improving the body pressure distribution of the body pressure dispersing member 30, it is preferable that the upper surface 30a of the body pressure dispersing member 30 is provided with unevenness.

[0064] In addition, in the pillow 1 according to the embodiment, the upper surface 30a of the body pressure dispersing member 30 is provided with unevenness. However, this is not limited to this. In addition to the upper surface 30a of the body pressure dispersing member 30, the lower surface may also be provided with unevenness.

[0065] Moreover, in the holding member 10 of the pillow 1 according to the embodiment, the upper surface 10b is an inclined surface that inclines so as to become higher from the front (-Y side) of the pillow 1 toward the back side +Y side. However, this is not limited to this. As long as the holding member 10 has a shape that can hold the pillow base 20 in an inclined state, the upper surface 10b is not limited to an inclined surface. For example, the upper surface 10b of the holding member 10 may be formed in a shape that becomes higher in a gentle step-like or curved shape from the front (-Y side) of the pillow 1 toward the back side +Y side.

[0066] In this embodiment, as shown in Fig. 9(A)-(D), the fillers B-1, B-2, B-3, and B-4 are cylindrical beads with a diameter of 5 mm or small granular cotton with a diameter of about 3-5 mm. However, the fillers B-1, B-2, B-3, and B-4 shown in Fig. 9(A)-(D) are only examples. The fillers B-1, B-2, B-3, and B-4 may be other than those shown in Fig. 9(A)-(D) depending on the user's body type and preferences.

[0067] Also, as shown in FIG. 4, the pillow 1 according to the embodiment includes one holding member 10. However, this is not limited to this. The pillow 1 may include two or more holding members 10. Also, for example, a plurality of types of holding members 10 with different inclination angles may be combined. By combining a plurality of types of holding members 10 with different inclination angles, the inclination angle of the pillow 1 can be easily changed according to the user's body type and preferences. As a result, the user of the pillow 1 can get a good night's sleep.
