Mode for Carrying Out the Invention

[0013] Next, the pillow according to the present invention will be described below with reference to the accompanying drawings by giving preferred examples. Note that the embodiments and drawings described below are examples of a part of the embodiments of the present invention, and are not used for the purpose of limiting to these configurations, and can be appropriately changed without departing from the gist of the present invention.

Example

[0014] As shown in FIG. 1, the pillow 10 according to the example includes a pillow body 12 having a foam layer, an installation portion 14 formed on the lower surface of the pillow body 12, through holes 16 and 18 penetrating from the installation portion 14 to the upper surface of the pillow body 12, and an illumination portion 20 disposed in the installation portion 14 and irradiating light toward the through holes 16 and 18. Further, the pillow 10 of the example includes a sheet 26 disposed on the lower surface of the pillow body 12. The pillow 10 of the example is for placing the user's head. Unless otherwise specified, when a person uses it, the direction in the height direction of the person is referred to as the vertical direction, and the direction in the shoulder width direction when a person uses it is referred to as the horizontal direction. Also, the direction in the up-down direction when the pillow 10 is used is referred to as the thickness direction.

[0015] The shape of the pillow body 12 may be any shape that functions as the pillow 10 and is not particularly limited. Note that the pillow body 12 of the example is formed in a shape suitable for placing the user's head. As shown in FIGS. 2 and 3, the pillow body 12 is formed to be high (thick) at both lateral edge portions and low (thin) at the lateral central portion where the head is placed. As shown in FIG. 4, the pillow body 12 is formed to be high (thick) at both longitudinal edge portions and low (thin) at the longitudinal central portion where the head is placed.

[0016] The pillow body 12 is formed of only a foam layer, or a combination of a foam layer and a material other than foam such as fibers. The pillow body 12 of the embodiment is entirely formed of a foam layer. As the foam layer, it is desirable to form it with polyurethane foam because it is lightweight and easy to control physical properties, but it is not limited to this, and it may be an olefin foam such as polyethylene or a rubber foam. Further, the foam is not particularly limited, but a so-called low-rebound foam having a resilience ratio of 20% or less (conforming to JIS K 6400) is preferable. As the low-rebound foam, more preferably, the resilience ratio is greater than 0 and 20% or less, the hardness is 20 N to 100 N, and the density is 30 kg / m 3 ~100 kg / m 3 , and examples thereof include a polyurethane slab foam or a molded foam having a compression residual strain of 1% to 10% (all physical property values conform to JIS K 6400).

[0017] As shown in FIG. 5, the installation portion 14 is formed in a concave shape on the lower surface of the pillow body 12. The installation portion 14 is disposed at a position deviated from the center in the lateral direction of the pillow body 12 on the lower surface of the pillow body 12. In the embodiment, two installation portions 14 are formed separately on the left and right sides with the center in the lateral direction of the pillow body 12 interposed therebetween. Further, the installation portion 14 is formed in a shape that matches the outer shape of the lighting portion 20. Specifically, the installation portion 14 of the embodiment is formed in a vertically long rectangular shape in accordance with the outer shape of the vertically long rectangular lighting portion 20 in plan view (see FIG. 1).

[0018] As shown in FIG. 1, the pillow body 12 has a first through hole 16 and a second through hole 18 whose opening area is smaller than that of the first through hole 16 as through holes for lighting and ventilation. These through holes 16 and 18 open at positions deviated from the center in the lateral direction of the pillow body 12 on the upper surface of the pillow body 12. The pillow 10 of the embodiment has right-side ventilation holes 16 and 18 disposed at a distance from the center in the lateral direction of the pillow body 12 to the right, and left-side ventilation holes 16 and 18 disposed at a distance from the center in the lateral direction of the pillow body 12 to the left. Further, on the upper surface of the pillow body 12 having a concave shape with the center in the lateral direction at the bottom, the ventilation holes 16 and 18 are disposed at positions shifted to the left and right from the bottom of the concave shape.

[0019] As shown in FIG. 1, the first through-hole 16 has an elongated hole shape. Here, examples of the elongated hole shape include an opening shape composed of two arcs connected by a straight line as in the embodiment, but are not limited thereto. For example, it may be an opening shape such as a rectangle or an ellipse, in which one side is longer than the other side orthogonal to this side. In the embodiment, a plurality of first through-holes 16 are arranged on each of the left and right side portions on the upper surface of the pillow body 12, and the first through-holes 16 are not provided at the lateral center portion of the pillow body 12. The first through-hole 16 opens at a position deviated from the lateral center on the upper surface of the pillow body 12. Further, the first through-hole 16 extends linearly in the thickness direction of the pillow body 12 and opens at the upper surface (ceiling surface) of the installation portion 14 formed in a concave shape on the lower surface of the pillow body 12 (see FIGS. 2 to 4).

[0020] The longitudinal direction of the first through-hole 16 extends in a direction intersecting the lateral direction of the pillow 10. More specifically, in the first through-hole 16, the longitudinal direction of the opening shape on the surface side of the pillow body 12 extends so as to incline in the vertical direction (the direction of the user's head top (embodiment) or the neck direction) as it goes from the lateral center portion side of the pillow body 12 toward the lateral outside.

[0021] As shown in FIGS. 2 to 4, the opening area of the first through-hole 16 may be the same in the thickness direction of the pillow body 12 as in the embodiment, but is not limited thereto. For example, the first through-hole 16 may increase the opening area from the lower side (the installation portion 14 side) to the upper side (the side opposite to the installation portion 14) of the pillow body 12, so that the opening area on the surface side of the pillow body 12 is larger than the opening area on the installation portion 14 side. Further, the first through-hole 16 may decrease the opening area from the lower side (the installation portion 14 side) to the upper side (the side opposite to the installation portion 14) of the pillow body 12, so that the opening area on the surface side of the pillow body 12 is smaller than the opening area on the installation portion 14 side.

[0022] As shown in Fig. 1, the pillow body 12 has second through holes 18 arranged side by side in the longitudinal direction of the first through hole 16. The second through holes 18 are formed with an opening dimension in the longitudinal direction smaller than that of the first through hole 16. In the second through holes 18 of the embodiment, the opening dimensions in the vertical and horizontal directions are the same. Specifically, the second through holes 18 of the embodiment are in the shape of round holes. Further, in the embodiment, a plurality of second through holes 18 are arranged on each of the left and right side portions on the upper surface of the pillow body 12, and the second through holes 18 are not provided at the lateral center portion of the pillow body 12. The second through holes 18 open at positions deviated from the lateral center on the upper surface of the pillow body 12. Also, the second through holes 18 extend linearly along the thickness direction of the pillow body 12 and open at the upper surface (ceiling surface) of the installation portion 14 formed in a concave shape on the lower surface of the pillow body 12 (see Figs. 2 to 5).

[0023] As shown in Figs. 2 to 4, the opening area of the second through holes 18 may be the same in the thickness direction of the pillow body 12 as in the embodiment, but is not limited thereto. For example, the second through holes 18 may increase the opening area from the lower side (the installation portion 14 side) to the upper side (the side opposite to the installation portion 14) of the pillow body 12, so that the opening area on the surface side of the pillow body 12 is larger than the opening area on the installation portion 14 side. Also, the second through holes 18 may decrease the opening area from the lower side (the installation portion 14 side) to the upper side (the side opposite to the installation portion 14) of the pillow body 12, so that the opening area on the surface side of the pillow body 12 is smaller than the opening area on the installation portion 14 side.

[0024] Although not particularly limited, it is preferable that the shortest opening dimension of the through holes 16 and 18 is 4 mm or more. By doing so, when the pillow 10 is used, the through holes 16 and 18 are less likely to be blocked by compression, and the air permeability for light transmission and heat dissipation can be ensured, and the through holes 16 and 18 can be easily formed.

[0025] As shown in FIG. 1, the pillow body 12 has, in addition to the through holes 16 and 18 described above, a first ventilation hole 22 that penetrates the pillow body 12 in the thickness direction and a second ventilation hole 24 that penetrates the pillow body 12 in the lateral direction. In the embodiment, a plurality of first ventilation holes 22 are arranged at the lateral center of the pillow body 12. Therefore, the plurality of first ventilation holes 22 open between the plurality of through holes 16 and 18 arranged at positions deviated from the lateral center on the upper surface of the pillow body 12. In other words, the through holes 16 and 18 are arranged on the left or right side of the central portion of the pillow body 12 where the first ventilation hole 22 is provided. The second ventilation hole 24 extends in the horizontal direction and opens on the left and right side surfaces of the pillow body 12. The second ventilation hole 24 is connected to a part of the first through hole 16, the second through hole 18, and the first ventilation hole 22 that overlap in the middle in the lateral direction (see FIGS. 2 and 4).

[0026] Examples of the lighting unit 20 include known lighting fixtures having light sources such as organic EL (organic electro-luminescence), LED (light emitting diode), electric bulbs, and fluorescent lamps. Among these, a lighting unit 20 using organic EL with less light that has an adverse effect on sleep, such as blue light, as a light source is preferable. In addition, organic EL also has the advantage of being able to dissipate heat generated when irradiating light in a planar manner.

[0027] As shown in FIGS. 2 to 4, the lighting unit 20 is arranged in a state of being in contact with the upper surface where the through holes 16 and 18 in the installation portion 14 open. In addition, the lighting unit 20 is fitted and attached to the installation portion 14. As described above, since the installation portion 14 is formed in accordance with the outer shape of the lighting unit 20, the lighting unit 20 arranged in the installation portion 14 is in contact with the installation portion 14. As shown in FIG. 1, the lighting unit 20 is connected to the power supply 30 via the cord 28, and can be controlled to turn on, dim, or turn off by the user operating the operation unit 32.

[0028] As shown in FIGS. 2 to 4, the sheet 26 is disposed on the lower surface of the pillow body 12 in order to position the lighting unit 20 disposed in the installation portion 14. As the sheet 26, one having air permeability is used, and examples thereof include fabrics such as woven fabrics and non-woven fabrics.

[0029] The above-described pillow 10 may be covered with an outer surface with a cover (not shown) such as a bag shape. As the cover, one having air permeability and light transmittance is preferable, and examples thereof include fabrics such as woven fabrics.

[0030] When the above-described pillow 10 turns on the lighting unit 20 disposed in the installation portion 14 of the pillow body 12 by operating the operation unit 32, the light emitted from the lighting unit 20 passes through the through holes 16 and 18 penetrating from the installation portion 14 to the upper surface of the pillow body 12 and leaks to the upper surface of the pillow body 12. As a result, on the upper surface of the pillow body 12, the through holes 16 and 18 and the periphery of the through holes 16 and 18 emit light, so that the pillow 10 itself can be used as a night light or a bedside light. According to the above-described pillow 10, since the light of the lighting unit 20 can be passed through the through holes 16 and 18 to cause the upper surface (surface) of the pillow body 12 to emit light, whether it is used as lighting or as a pillow 10, there is no particular trouble such as opening and closing an opening for lighting, and it is easy to use. Here, in the pillow 10, since the through holes 16 and 18 are opened at positions deviated from the horizontal center on the upper surface of the pillow body 12, even when the head is placed, the through holes 16 and 18 are deviated from the head.

[0031] Since the pillow 10 has a foam layer in the pillow body 12, the heat generated by the lighting unit 20 can be made difficult to be transmitted to the user due to the heat insulation property peculiar to the foam. Further, even if the pillow body 12 has a foam layer, since the through holes 16 and 18 penetrate from the installation portion 14 to the upper surface of the pillow body 12, the heat generated by the lighting unit 20 disposed in the installation portion 14 can escape from the through holes 16 and 18 to the outside of the pillow 10. In the pillow 10 of the embodiment, since some of the through holes 16 and 18 are connected to the second ventilation holes 24 that open to the side surface of the pillow body 12, the heat generated by the lighting unit 20 disposed in the installation portion 14 can escape from not only the through holes 16 and 18 but also the second ventilation holes 24 to the outside of the pillow 10.

[0032] Since the pillow 10 has the first through hole 16 in the shape of a long hole in the pillow body 12, an opening area that can easily pass the light and heat of the lighting unit 20 can be secured by one long width of the first through hole 16. On the other hand, since the other width of the first through hole 16 is narrow, it is possible to make it difficult for the user to recognize the presence of the first through hole 16.

[0033] The pillow 10 has the second through holes 18 arranged side by side in the longitudinal direction of the first through hole 16 and having a smaller opening dimension in the longitudinal direction than the first through hole 16, so that the strength reduction of the pillow body 12 can be suppressed more than when a plurality of first through holes 16 are arranged side by side in the longitudinal direction. Further, since the pillow 10 has the first through hole 16 and the second through hole 18 having a smaller opening area than the first through hole 16, for example, appropriate light that is not dazzling, such as a night light, can be passed through in a well-balanced manner.

[0034] If the longitudinal direction of the first through hole 16 that opens on the upper surface of the pillow body 12 extends in a direction intersecting the lateral direction of the pillow 10, even when the user changes the posture, such as turning over, it is possible to make it difficult to crush the first through hole 16 having a long hole shape.

[0035] (Modification example) Not limited to the above-described matters, for example, the following may be used. Note that the present invention is not limited only to the specific descriptions of the embodiments and the following modification examples. (1) Although the installation portion of the embodiment is formed on the lower surface of the pillow body, it is not limited thereto, and as shown in FIGS. 6 to 8, the installation portion 14 may be formed inside the pillow body 12. (2) Although the through holes of the embodiment are formed so as to penetrate from the installation portion to the upper surface of the pillow body, it is not limited thereto, and as shown in FIGS. 6 to 8, the through holes 16 and 18 may be formed so as to penetrate from the installation portion 14 to the side surface of the pillow body 12. Further, through holes penetrating from the installation portion to the upper surface and the side surface of the pillow body may be provided, or through holes penetrating from the installation portion to the upper surface of the pillow body and through holes penetrating from the installation portion to the side surface of the pillow body may be provided. (3) The arrangement range of the through holes in the pillow body is not limited to the embodiment and can be appropriately changed. (4) In the embodiment, it has the first through-hole having a long hole shape and the second through-hole having an opening area smaller than that of the first through-hole, but it is not limited thereto, and it may be only the first through-hole or only the second through-hole. (5) In the embodiment, a pillow on which a user's head is placed is exemplified, but it is not limited thereto, and for example, it may be a hugging pillow, a footrest on which parts other than the head are placed, or the like.
