[0003] [Patent Document 1] JP 2004-130036 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the pillow of the above-mentioned Patent Document 1, the spring is inserted into the hole, so the displacement direction of the spring is restricted to the up and down direction. Therefore, even if you try to tilt your head to turn over in your sleep, the entire floating pillow part will simply sink, making it difficult to tilt your head smoothly.

[0005] The present invention has been made in consideration of the above circumstances, and has as its main object to provide bedding that makes it easier to tilt the head, a manufacturing method for a pillow component, a manufacturing program for a pillow component, and a manufacturing device for a pillow component. [Means for solving the problem]

[0006] In order to solve the above problems, the bedding of the present invention comprises: A bedding having a pillow part on which a sleeper rests his / her head, The pillow portion is The pillow body and A storage space formed in the pillow body; A pillow structure provided in the storage space, The pillow structure includes: A head receiving portion for receiving the head of the sleeper from below; A support portion that extends downward from a substantially central portion of the head receiving portion and supports the head receiving portion from below; It has The support portion is configured to be tiltable in a direction intersecting the up-down direction. Effect of the Invention

[0007] According to the bedding of the present invention, when the sleeper's head is placed on the pillow portion, the head of the sleeper is received by the head receiving portion of the pillow component provided in the storage space of the pillow body. A support portion extends downward from the approximate center of the head receiving portion, and the support portion is configured to be tiltable. In this case, when the sleeper tilts his / her head and a downward load acts on a position shifted from the center of the head receiving portion, the support portion tilts, and the head receiving portion becomes tilted. This makes it easier for the sleeper to tilt his / her head. [Brief description of the drawings]

[Figure 7]FIG. 11 is a diagram for explaining the function of the pillow structure. [Figure 8] FIG. 1 is a diagram showing a schematic configuration of a manufacturing apparatus. [Figure 9] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a vertical cross-sectional view showing the configuration of the pillow. Fig. 2 (a) is a bottom view showing the pillow body, and (b) is a bottom view showing the back cover. In the following description, the direction perpendicular to the left-right direction in a plan view is defined as the front-rear direction.

[0010] As shown in Fig. 1, the pillow 10 includes a pillow body 11, a pillow cover 12, a pillow component 13, and a back cover 14. The pillow body 11 is made of a material having cushioning properties, for example, high-density, high-resilience urethane. The pillow 10 corresponds to the pillow portion and the bedding.

[0011] As shown in Fig. 2(a), the pillow body 11 is formed in a flat rectangular parallelepiped shape. The pillow body 11 has an accommodation space 16 for accommodating the pillow constituent body 13. The accommodation space 16 is a concave space that opens downward, and is formed in a cylindrical shape extending in the vertical direction. The accommodation space 16 is located in the center of the pillow body 11 in a plan view, and its upper part is closed by the pillow body 11. In other words, the pillow body 11 has a cover part 11a that covers the accommodation space 16 from above, and the cover part 11a is integrally formed with a surrounding part 11b provided around the cover part 11a in the pillow body 11.

[0012] A back cover 14 is provided on the underside of the pillow main body 11. The back cover 14 is formed of, for example, urethane foam. The back cover 14 covers the accommodation space 16 from below when the pillow constituent body 13 is accommodated in the accommodation space 16. In this case, the pillow constituent body 13 is placed on the upper surface of the back cover 14. As shown in FIG. 2(b), the back cover 14 is formed in a rectangular plate shape that is long in the front-rear direction, and the length in the front-rear direction is approximately the same as the length of the pillow main body 11 in the front-rear direction.

[0013] The back cover 14 is disposed in a recess 17 formed on the underside of the pillow body 11. The recess 17 is a groove extending in the front-rear direction, and both sides in the front-rear direction are open. The recess 17 is formed in the center of the pillow body 11 in the left-right direction, and is continuous with the storage space 16. The recess dimension (dimension in the up-down direction) of the recess 17 is the same as the thickness dimension of the back cover 14. Therefore, when the back cover 14 is disposed in the recess 17, the underside of the back cover 14 and the underside of the pillow body 11 are approximately flush with each other.

[0014] With the back cover 14 placed in the recess 17, the pillow body 11 is covered with the pillow cover 12. In this case, the back cover 14 is covered by the pillow cover 12 together with the pillow body 11. This prevents the back cover 14 from coming off the recess 17, and thus prevents the pillow component 13 from falling off the storage space 16.

[0015] Next, the pillow-constituting body 13 will be described with reference to Fig. 3 to Fig. 6. Fig. 3 is a perspective view showing the pillow-constituting body 13, Fig. 4 is a plan view, Fig. 5 is a front view, and Fig. 6 is a vertical cross-sectional view. Fig. 6 corresponds to the cross-sectional view taken along line AA in Fig. 4.

[0016] As shown in Fig. 3 to Fig. 6, the pillow-constituting body 13 includes a head receiving part 21 that receives the head of the sleeper, and a support part 22 that supports the head receiving part 21 from below. The pillow-constituting body 13 is formed from a synthetic resin material, for example, nylon resin. The pillow-constituting body 13 is also formed by a 3D printer (three-dimensional modeling device). Therefore, the head receiving part 21 and the support part 22 of the pillow-constituting body 13 are integrally formed as a 3D printer modeled object.

[0017] The head receiving portion 21 is dish-shaped (dish-shaped) with a center portion recessed downward, and is circular in plan view. In other words, the head receiving portion 21 is formed in a concave shape that opens upward. The head receiving portion 21 is partially hollowed out, so that a plurality of openings 24 are formed in the head receiving portion 21 that penetrate in the thickness direction. In this case, the head receiving portion 21 has a plurality of beam portions 25 that define these openings 24, and the plurality of beam portions 25 are connected to each other.

[0018] The beams 25 include an annular beam 25a that constitutes the outer periphery of the head receiving portion 21, and a plurality of beams 25b that extend from the beam 25a toward the center of the head receiving portion 21. The beams 25b are connected to each other via a disk-shaped central plate 26. The central plate 26 is formed so that its center is located in the center of the head receiving portion 21, and its outer diameter is larger than the width of the beams 25b.

[0019] The support part 22 is formed in a spiral plate shape with its center (spiral center) at a central axis E that passes through the center of the head receiving part 21 and extends in the vertical direction. In this case, the plate surface of the support part 22 faces the vertical direction. The support part 22 extends downward from the center of the head receiving part 21 in a spiral plate shape. The upper end part of the support part 22 is connected to a central plate part 26 of the head receiving part 21.

[0020] The support portion 22 has a rectangular shape in plan view, specifically a square shape. In other words, the outer edge 29 of the support portion 22 has a square shape in plan view. The center of the support portion 22 is located on the central axis E of the head receiving portion 21 in plan view. The size of the support portion 22 in plan view is smaller than that of the head receiving portion 21, and therefore, the entire outer periphery of the head receiving portion 21 extends beyond the outer edge 29 of the support portion 22 in plan view.

[0021] An inner edge 28 of the spiral plate-shaped support part 22 is located on the central axis E of the head receiving part 21. As a result, the support part 22 has a portion that extends vertically along the central axis E of the head receiving part 21. Hereinafter, this portion will be referred to as a shaft part 31. The shaft part 31 extends downward from the center of the head receiving part 21 along the central axis E. The shaft part 31 extends continuously over the entire area of ​​the support part 22 in the vertical direction.

[0022] Specifically, the shaft portion 31 extends vertically in a spiral manner along the central axis E of the head receiving portion 21. However, the shaft portion 31 may extend in a round bar shape along the central axis E of the head receiving portion 21. In short, it is sufficient for the shaft portion 31 to extend continuously in the vertical direction along the central axis E.

[0023] In the support part 22, the outer circumferential side of the shaft part 31 is a spiral part 32. The spiral part 32 is a part that extends in a spiral plate shape while going around the shaft part 31. The spiral part 32 is connected to the shaft part 31 on its inner circumferential side and spreads outward in the radial direction from the shaft part 31. The spiral part 32 is partially hollowed out, so that a plurality of openings 34 that penetrate the spiral part 32 in the plate thickness direction are formed. The spiral part 32 has a shape in which a plurality of beam parts 35 that define the openings 34 are connected to each other. Note that the openings 34 are not shown in FIG. 6.

[0024] The support portion 22 has a horizontal plate-like base portion 33 at its lower end. The support portion 22 extends upward from the base portion 33 in a spiral plate shape. The lower end of the shaft portion 31 is connected to the base portion 33. The shaft portion 31 is capable of bending and deforming in a direction intersecting the length direction with the lower end connected to the base portion 33 as a fulcrum. In other words, the shaft portion 31 is capable of bending and deforming in a direction intersecting (perpendicular to) the vertical direction. In this case, the shaft portion 31 is bent in the above direction, so that the shaft portion 31 as a whole is inclined in the above direction. Therefore, the shaft portion 31 is capable of bending in a direction intersecting the vertical direction with the lower end as a fulcrum (see also Figs. 7(b) and (c)). In this case, the shaft portion 31 is capable of bending in all directions in a plan view.

[0025] When the shaft portion 31 is tilted in a direction intersecting the up-down direction, the helical portion 32 provided on the outer periphery of the shaft portion 31 is elastically deformed accordingly. In detail, the helical portion 32 is deformed so that the plate-shaped portion constituting the helical portion 32 is tilted toward the tilting side, and as a result, the helical portion 32 as a whole is inclined toward the tilting side. Therefore, in this case, the entire support portion 22 including the shaft portion 31 and the helical portion 32 is inclined toward the tilting side. Therefore, the support portion 22 is tiltable in a direction intersecting the up-down direction. The helical portion 32 corresponds to the elastic deformation portion.

[0026] Of the support part 22, a portion of the upper end side that is connected to the head receiving part 21 (hereinafter referred to as the connecting side part 37) is formed so that the outer edge 29 is located inside compared to the portion below it (hereinafter referred to as the normal part 38). In detail, in the normal part 38, the entire area of ​​the outer edge 29 is located on the outer edge line of the same square (hereinafter referred to as the reference square) in a plan view, whereas in the connecting side part 37, the entire area of ​​the outer edge 29 is located inside the outer edge line of the reference square in a plan view. More specifically, in the connecting side part 37, the position (in a plan view) of the outer edge 29 gradually shifts inward from the outer edge line of the reference square as it moves from the lower end to the upper end of the outer edge 29.

[0027] The pillow constituent body 13 described above is disposed in the storage space 16 of the pillow body 11, as shown in Fig. 1. The pillow constituent body 13 is disposed in a state in which the base part 33 is placed on the upper surface of the back cover 14. The height dimension of the pillow constituent body 13 is approximately the same as the distance between the back cover 14 and the cover part 11a of the pillow body 11. Therefore, when the pillow constituent body 13 is disposed in the storage space 16, the head receiving part 21 of the pillow constituent body 13 is in contact with or in close proximity to the cover part 11a of the pillow body 11.

[0028] The outer diameter of the head receiving portion 21 is approximately the same as the inner diameter of the accommodation space 16, and more specifically, is slightly smaller than the inner diameter of the accommodation space 16. In this case, when the pillow component 13 is disposed in the accommodation space 16, the outer edge 29 of the support portion 22 and the inner peripheral surface of the accommodation space 16 are spaced apart from each other. Therefore, a sufficient space is secured on the outer peripheral side of the support portion 22 in the accommodation space 16 for the support portion 22 to tilt. The pillow main body 11 is formed with sufficient cushioning (flexibility) so as not to hinder the tilting of the support portion 22 and the associated tilting of the head receiving portion 21.

[0029] Next, the function of the pillow-constituting body 13 will be described with reference to Fig. 7. Fig. 7 is a diagram for explaining the function of the pillow-constituting body 13.

[0030] As shown in FIG. 7(a), when a sleeper places his / her head H on the pillow 10, the back of the head H is placed on the center of the pillow 10. As a result, the sleeper's head H is supported by the head receiving part 21 of the pillow component 13 via the cover part 11a of the pillow main body 11. In this case, a downward load acts on the center of the head receiving part 21. Here, since the support part 22 has an axis part 31 extending along the central axis E of the head receiving part 21, in this case, the head receiving part 21 is prevented from sinking.

[0031] Next, as shown in Fig. 7(b), when the sleeper tilts his / her head H to the left and tries to turn over, a downward load acts on a portion of head receiving portion 21 that is shifted to the left from the center. In this case, support portion 22 tilts to the left, and head receiving portion 21 also tilts to the left as a result of this tilt. Specifically, in this case, head receiving portion 21 tilts to the left while shaft portion 31 prevents head receiving portion 21 from sinking. This makes it easier for the sleeper to tilt his / her head to the left and turn over.

[0032] Similarly, as shown in Fig. 7(c), when the sleeper tilts his / her head H to the right and tries to turn over, the support part 22 tilts to the right, and accordingly the head receiving part 21 tilts to the right. Therefore, the sleeper can easily tilt his / her head to the right and turn over.

[0033] Next, the flow of manufacturing the pillow component 13 will be described with reference to Figures 8 and 9. Figure 8 is a diagram showing a schematic configuration of a manufacturing device 40, and Figure 9 is a diagram showing the flow of the manufacturing process.

[0034] As shown in Fig. 8, a manufacturing device 40 is used to manufacture the pillow-constituting body 13. The manufacturing device 40 includes a 3D printer 41 and a manufacturing terminal 42 connected to the 3D printer 41. The terminal 42 is made of a personal computer and corresponds to a "computer." A manufacturing program 43 for manufacturing the pillow-constituting body 13 is stored in the terminal 42. The terminal 42 (more specifically, the control unit of the terminal 42) carries out the manufacturing process of the pillow-constituting body 13 by the 3D printer 41 based on the manufacturing program 43.

[0035] In the manufacturing process, as shown in Fig. 9, the terminal 42 acquires input data related to the three-dimensional structure of the pillow-constituting body 13 (step S11). For example, the input data is stored in advance in a storage unit of the terminal 42, and the input data is read out and acquired from the storage unit. Also, another terminal in which the input data is stored may be accessed, and the input data may be acquired from the other terminal.

[0036] Next, the terminal 42 outputs the acquired input data to the 3D printer 41, and causes the 3D printer 41 to form a three-dimensional structure corresponding to the input data (step S12). In this way, the pillow-forming body 13 is manufactured.

[0037] According to the configuration of this embodiment described in detail above, the following excellent effects can be obtained.

[0038] The pillow component 13 is provided in the storage space 16 of the pillow body 11, and the pillow component 13 is configured to have a head receiving portion 21 that receives the head of the sleeper, and a support portion 22 that extends downward from the center of the head receiving portion 21 and supports the head receiving portion 21 from below. The support portion 22 is also configured to be tiltable in a direction intersecting the left-right direction. With this configuration, when the sleeper tilts his / her head and a downward load acts on a position shifted from the center of the head receiving portion 21, the support portion 22 tilts, causing the head receiving portion 21 to be in a tilted state. This makes it easier for the sleeper to tilt his / her head.

[0039] Since the support portion 22 can be tilted left and right, it is easy to tilt the head left and right, and to turn over in sleep.

[0040] The support portion 22 has an axis portion 31 that extends downward from the center of the head receiving portion 21 along the central axis E of the head receiving portion 21. When the back of the head is placed on the head receiving portion 21, a downward load acts on the center of the head receiving portion 21. In this case, the axis portion 31 can prevent the head receiving portion 21 from sinking downward. On the other hand, when the sleeper tilts his / her head and a downward load acts on a position shifted from the center of the head receiving portion 21, the head receiving portion 21 will tilt while being prevented from sinking. This makes it easier to tilt the head.

[0041] The support part 22 is configured to have a shaft part 31 that can be tilted in a direction intersecting the left-right direction, and a spiral part 32 on the outer periphery of the shaft part 31 that elastically deforms as the shaft part 31 is tilted. In this configuration, when the shaft part 31 is tilted and the head receiving part 21 is tilted, an elastic force acts on the shaft part 31 in the direction returning the shaft part 31 to its original position, and an elastic force acts on the head receiving part 21 in the direction returning the head to its original position. Therefore, when tilting the head, the head can be supported from the side that the head is tilted and the head can be felt as if it is floating, allowing the head to be tilted while feeling comfortable.

[0042] When a sleeper tilts his / her head by turning over in his / her sleep, it is expected that the head will tilt not only left and right but also forward and backward. In the above embodiment, the shaft portion 31 can be tilted in all directions in a plan view, so that the head can be tilted in a natural state. In addition, the elastic deformation portion provided on the outer periphery of the shaft portion 31 is the spiral portion 32 that spirally circles around the shaft portion 31, so that the spiral portion 32 elastically deforms regardless of the direction in which the shaft portion 31 is tilted, and an elastic force acts on the shaft portion 31 and thus the head receiving portion 21 in the direction of returning it to its original state. As a result, when tilting the head in any direction, the head can be tilted while feeling a comfortable floating sensation.

[0043] · Because the support part 22 is formed in the shape of a spiral plate centered on the central axis E of the head receiving part 21, the support part 22 can be tilted in all directions in a plan view. This makes it easier to tilt the head in a natural state. Also, by positioning the inner edge of the support part 22 on the central axis E of the head receiving part 21, a part that extends up and down along the central axis E (i.e., shaft part 31) is formed in part of the support part 22. In this case, the head receiving part 21 can be prevented from sinking by the above-mentioned extending part, so that when the head is tilted, the head receiving part 21 can be tilted while preventing the head receiving part 21 from sinking. This makes it easier to tilt the head.

[0044] In addition, because the support part 22 is in the shape of a spiral plate, when the support part 22 tilts and the head receiving part 21 tilts, the support part 22 is in an elastically deformed state, and as a result, an elastic force acts on the head receiving part 21 in the direction of returning it to its original state. Therefore, when tilting the head, the head is supported from the tilted side and the user feels as if the head is floating, allowing the head to be tilted while feeling comfortable.

[0045] Of the spiral plate-shaped support part 22, a portion of the upper end side, which is the connecting side with the head receiving part 21, is considered to deform integrally with the head receiving part 21. Therefore, it is considered that the portion of the upper end side of the support part 22 is a portion that does not affect the deformation of the support part 22. Therefore, in the above embodiment, focusing on this point, the portion of the upper end side of the support part 22 (connecting side portion 37) is formed so that the outer edge 29 is located inside compared to the portion below it (normal portion 38). In this case, it is possible to reduce the material of the support part 22 without affecting the deformation of the support part 22.

[0046] Since the head receiving portion 21 is formed in a concave shape that opens upward, the head of the sleeper can be positioned by being wrapped around it. In addition, when the sleeper tilts his / her head, the head receiving portion 21 can easily tilt in accordance with the movement of the head.

[0047] Since the storage space 16 is opened downward, the pillow component 13 can be removed from the storage space 16. This makes it convenient to wash the pillow 10. In addition, a back cover 14 is provided to cover the storage space 16 from below, and the pillow component 13 is placed on the back cover 14. In addition, a recess 17 recessed by the same amount as the thickness of the back cover 14 is provided on the underside of the pillow main body 11, and with the back cover 14 placed in the recess 17, the pillow main body 11 and the back cover 14 are covered together by the pillow cover 12. In this case, the back cover 14 is stable, and as a result, the pillow component 13 can be stably placed on the back cover 14.

[0048] The pillow body 11 is provided with a covering portion 11a that covers the accommodation space 16 from above, and the covering portion 11a is integrally formed with a surrounding portion 11b that is provided around the covering portion 11a in the pillow body 11. This allows the head to be placed on the head receiving portion 21 via the covering portion 11a of the pillow body 11, and the cushioning properties of the pillow body 11 can be suitably obtained.

[0049] In the pillow component 13, the head receiving portion 21 and the support portion 22 are integrally formed by the 3D printer 41. This allows easy molding even if the support portion 22 has a complicated structure formed in a spiral plate shape. Also, for example, in a configuration in which the head receiving portion 21 and the support portion 22 are formed as separate members and then integrated by gluing or the like, if stress concentration due to the load of the head occurs at the joint between the head receiving portion 21 and the support portion 22, there is a risk that the head receiving portion 21 and the support portion 22 will separate at the joint. On the other hand, a configuration in which the head receiving portion 21 and the support portion 22 are integrally formed as a 3D printer modeled object has the advantage of making such separation less likely to occur.

[0050] The head receiving portion 21 is partially hollowed out to form a shape in which multiple beams 25 are interconnected. Similarly, the support portion 22 is also partially hollowed out to form a shape in which multiple beams 35 are interconnected. In this case, it is possible to ensure molding speed while keeping material costs down. Also, by forming a shape in which multiple beams 25, 35 are combined, rather than simply hollowing out, it is possible to obtain the above-mentioned effects while suppressing a decrease in head support strength.

[0051] The present invention is not limited to the above embodiment, and may be implemented, for example, as follows.

[0052] (1) In the above embodiment, the shaft portion 31 and the spiral portion 32 (corresponding to the elastically deformable portion) are integrally formed in the support portion 22 of the pillow component 13, but the spiral portion 32 may be formed separately from the shaft portion 31. Specifically, it is conceivable to configure the support portion 22 to have a rod-shaped shaft portion extending downward from the center of the head receiving portion 21 and having a lower end fixed to the base portion 33, and a spiral portion formed separately from the shaft portion and extending spirally around the shaft portion. In this case, the spiral portion may or may not be fixed to the shaft portion. Even in such a configuration, the spiral portion will elastically deform with the inclination of the shaft portion. In addition, in this case, the spiral portion is not limited to a spiral plate shape, and may be a coil shape in which a wire is wound in a spiral shape. In that case, for example, it is conceivable to use a coil spring as the spiral portion.

[0053] (2) In the above configuration (1) in which the helical portion (corresponding to the elastic deformation portion) is provided separately from the shaft portion, an elastic member made of a rubber material may be used as the elastic deformation portion instead of the helical portion. In this case, it is conceivable to form the elastic member in a line shape that connects the shaft portion and the base portion 33 at an angle, and provide a plurality of such linear elastic members around the shaft portion. With this configuration, when the shaft portion is tilted, the elastic member is elastically deformed (i.e., stretched or contracted) in the longitudinal direction accordingly. Therefore, in this case as well, an elastic force can be applied to the shaft portion and, by extension, the head receiving portion 21 in the direction of returning it to its original state.

[0054] (3) In the above embodiment, the shaft portion 31 is configured to tilt as a result of bending, but the shaft portion may be configured to tilt as a result of rotating. For example, in the above-mentioned configuration (1), a configuration is conceivable in which the lower end of the shaft portion is rotatably connected to the base portion 33 via a rotating shaft extending in the front-rear direction. In that case, the shaft portion is configured to be rotatable in the left-right direction around the rotating shaft, and is configured to be tiltable in the left-right direction by the rotation.

[0055] (4) In the above embodiment, the outer edge 29 of the connecting portion 37 of the support part 22 is located inside the normal portion 38, but it does not necessarily have to be located inside. In other words, the outer edge 29 may be located on the outer edge line of the same square in a plan view over the entire vertical area of ​​the support part 22.

[0056] Furthermore, the outer edge 29 of the support portion 22 does not necessarily have to be square in plan view, but may be circular or have another shape.

[0057] (5) In the above embodiment, the head receiving portion 21 and the support portion 22 of the pillow component 13 are each hollowed out, but it is also possible to hollow out only one of the head receiving portion 21 and the support portion 22. Also, it is also possible not to hollow out both the head receiving portion 21 and the support portion 22.

[0058] (6) In the above embodiment, the pillow-constituting body 13 is formed by modeling using a 3D printer. However, for example, the pillow-constituting body 13 may be formed by resin molding or by processing such as cutting.

[0059] (7) In the above embodiment, the pillow component 13 is made of nylon resin, but it may be made of other resin materials. Also, it may be made of materials other than resin materials, such as metal materials and rubber materials.

[0060] (8) In the above embodiment, the pillow body 11 has the covering portion 11a that covers the storage space 16 from above, but the pillow body 11 may be configured not to have the covering portion 11a. In other words, the pillow body 11 may be formed so that the storage space 16 opens upward. In this case, the sleeper's head is placed on the head receiving portion 21 of the pillow component 13 only via the pillow cover 12. In addition, in the case of such a configuration, a cushioning material may be attached to the upper surface side of the head receiving portion 21.

[0061] Also, the storage space 16 may be a closed space that is not open to either the top or bottom, and the pillow component 13 may be provided in the closed space in a state where it cannot be removed.

[0062] (9) In the above embodiment, the present invention is applied to the pillow 10, but the present invention can be applied to any bedding that has a pillow portion, not limited to the pillow 10. For example, the present invention can be applied to a mattress with a pillow that has a pillow portion. [Explanation of symbols]
