Abstract

To provide a pillow which can move the head more naturally and make a person less likely to feel discomfort.SOLUTION: When a body tries to roll over, the head comes close from a bottom plate part 10 to a side plate part 20. With the head beginning to contact the side plate part 20, and with the side plate part 20 beginning to be pushed outward, since the outer side where the bottom plate part 10 connects to the side plate part 20 has the formation of an arc surface 30 in an arcuate cross section, the outer side starts to roll outward on a hard base 2. A pillow body 1 of a simplex rolls outside along with the rolling over of the body and, the rolling stops when the outer side of the side plate part 20 reaches the top face of the base 2. When the rolling-over state returns to a supine state, the head moves from the top of the side plate part 20 toward the bottom plate part 10, with the bottom plate part 10 starting to be pushed, and with the pillow body 1 rolling inward on the hard base 2. When the outer side of the bottom plate part 10 reaches the top face of the base 2, the rolling stops.SELECTED DRAWING: Figure 2

Description

[Technical field]

[0001] The present invention relates to a pillow that supports a person's head while sleeping. [Background technology]

[0002] There are various pillows that support a person's head when sleeping. Pillows that make it easier to turn over in sleep are known from Patent Documents 1 and 2. The pillow shown in Patent Document 1 has a center and left and right parts with different thicknesses so that the center is lower, and when you turn over in your sleep, your head is slightly elevated. This helps you maintain a natural body shape.

[0003] The pillow shown in Patent Document 2 has a central portion and left and right portions that are independent of each other, and the left and right portions can rotate so that they can be tilted outward from an upright position. When the head is in the central portion, the left and right portions stand along the sides of the head, but when the head turns over and tries to move to the right or left, it climbs onto one of the left and right portions, and at the same time, the left and right portions tilt outward and become horizontal. At this time, the upper surfaces of the left and right portions are higher than the central portion, so a natural body shape can be maintained. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3241366 [Patent Document 2] Patent Publication No. 2021-87693 Summary of the Invention [Problem to be solved by the invention]

[0005] In the case of the pillows shown in Patent Documents 1 and 2, when turning over in sleep, the head moves up to a higher position, which may cause discomfort. To provide a pillow that allows a user to easily turn over in their sleep without feeling uncomfortable. [Means for solving the problem]

[0006] The present invention is a pillow that supports a person's head when sleeping, having a cross section that is roughly L-shaped and a pillow body that extends in the direction of the person's height, and is formed into the roughly L shape by connecting a bottom plate and a side plate in an intersecting manner, and at least the outside of the edge where the bottom plate and the side plate are connected is formed into an arc-shaped cross section.

[0007] The following configurations can be combined with this single pillow: A pair of symmetrical pillow bodies are arranged side by side so that the cross section is roughly U-shaped with an upward opening. The relative angle of the pair of symmetrical pillow bodies can be changed within a specified angle range. The pillow body is placed on a base made of a plate material harder than the pillow body.

[0008] When a pair of symmetrical pillow bodies are placed side by side, the cross section becomes roughly U-shaped with an upward opening, and it is possible to place the head through this opening. At this time, the bottom plates of the left and right pillow bodies are in contact with each other, so the head can be placed on a roughly flat area. This state can be said to be no different from a normal pillow.

[0009] When the body tries to turn over, the head moves from the bottom plate to the side plate. When the head starts to contact the side plate, the side plate starts to be pushed outward. Then, because the outside of the edge where the bottom plate and the side plate are connected is formed with an arc-shaped cross section, it starts to roll outward on the hard base. As the head turns over, the single pillow rolls outward, and when the outside of the side plate reaches the top surface of the base, the rotation stops.

[0010] When turning over and returning to a supine position, the head moves from the top of the side plate to the bottom plate and begins to be pushed, causing the pillow to roll inward on the hard base. When the outside of the bottom plate reaches the top surface of the base, the rotation stops.

[0011] The above effects occur on both the left and right sides, but when turning over in sleep, the axis of rotation of the head does not coincide with the axis of rotation of the body, but often moves in an arc with the center of the body as the fulcrum, and this arc shape changes depending on the body type. Therefore, by changing the relative angle of the pair of symmetrical pillow bodies within a specified angle range, it becomes easier to match the arc shape of each individual, and it becomes easier to follow the movement of the head when turning over more naturally. Effect of the Invention

[0012] According to the pillow of the present invention, the head can be moved more naturally, and the user is less likely to feel uncomfortable. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of a pillow according to one embodiment of the present invention, FIG. 2 shows a front view of the pillow set in a set state, and FIG. 3 shows a plan view of the pillow set in a set state. In the figure, the pillow body 1 has a bottom plate portion 10 and a side plate portion 20. The bottom plate portion 10 and the side plate portion 20 are connected to each other so that the cross section is approximately L-shaped in the direction of the person's height. The bottom plate portion 10 and the side plate portion 20 have an appropriate softness as a pillow and are formed of a so-called cushion material. However, it is necessary to maintain the overall cross section approximately L-shaped. For this reason, in this embodiment, the core material of the bottom plate portion 10 and the side plate portion 20 is formed of an elastic foam material with sufficient hardness, and a urethane sponge with more flexibility is attached to the surface.

[0015] In addition, the bottom plate portion 10 and the side plate portion 20 can have a common connecting portion having, for example, perpendicular planes, and by extending plate material from each plane of this connecting portion, it is possible to make it appear as if the bottom plate portion 10 and the side plate portion 20 intersect in a perpendicular direction. In addition, although the edges are drawn as straight lines in each drawing, when a cover is placed over the cushioning material, the edges and corners of the product will be curved in appearance. Even in such a case, the cross section can be roughly said to be L-shaped.

[0016] The outside of the side where the bottom plate portion 10 and the side plate portion 20 are connected is formed with an arc surface 30 whose cross section is arc-shaped. In other words, the outside of the side where the bottom plate portion 10 and the side plate portion 20 are connected is like the outer peripheral surface of a cylinder. The angle range of the arc surface 30 is not particularly limited, but as described later, it is sufficient that the pillow body 1, which has an L-shaped cross section, can roll left and right by the arc surface 30.

[0017] Here, the angle at which the bottom plate portion 10 and the side plate portion 20 intersect is set to be slightly obtuse than 90 degrees, but it is not necessary to be limited to a clear angle. As an example, an angle of about 80 degrees to about 150 degrees can be said to be generally appropriate. However, the individual differences of the person using the pillow body 1 also have an effect. In addition, the angle at which the bottom plate portion 10 and the side plate portion 20 intersect does not need to be constant, and can be made variable by varying it depending on the part.

[0018] The thickness of the bottom plate portion 10 and the thickness of the side plate portion 20 are not the same, and as will be described later, the thickness of the bottom plate portion 10 is made thinner than the thickness of the side plate portion 20.

[0019] In addition, the bottom plate 10 and the side plate 20 have end faces on both sides in the length direction of the head, and the ends of the bottom plate 10 and the side plate 20 on the side of the human body are inclined surfaces 11, 21. These inclined surfaces 11, 21 are shaped to gradually move away from the person. However, when the cushioning material is covered with a cover to form the pillow body 1, the surface becomes curved and is unlikely to be a clearly inclined surface like a flat surface, but this case is also included in the inclined surfaces 11, 21. In this embodiment, the inclined surfaces 11 and 21 are used, but it is also possible to make the end surfaces of the bottom plate 10 and the side plate portion 20 approximately perpendicular to the other surfaces instead of inclining them. Also, it is also possible to make only one side, for example only the side of the inclined surface 11, an inclined surface. It is possible to form a bulge 12 as shown by the two-dot chain line at the end on the side of the human body in the valley where the bottom plate 10 and the side plate 20 are connected, that is, around where the inclined surfaces 11, 21 are connected. The pillow body 1 is covered with cushioning material, and although there are various ways to inflate it, it is expected to have the effect of improving comfort and making it easier to turn over in bed by touching the area around the neck, which is thinner than the head, when turning over in sleep.

[0020] As shown in Fig. 2, a pair of symmetrical pillow bodies 1 are arranged side by side so that the cross section is roughly U-shaped with an upward opening. The pair of pillow bodies 1 are placed on a base 2 made of a plate material harder than the pillow bodies 1.

[0021] FIG. 4 shows the pillow in a side view, and FIG. 5 shows a part of the pillow in an enlarged view. As shown in the figure, the pillow body 1 and the base 2 are connected by a hook-and-loop fastener 3 made of a flexible material so that the connected portion can roll. Therefore, the pillow body 1 can roll on the base 2 at the connected portion.

[0022] A hook-and-loop fastener 3a is sewn to the outside of the arc surface 30, which is the arc-shaped connecting portion of the pillow body 1, and a hook-and-loop fastener 3b is also attached to the upper surface of the base 2. As shown in FIG. 5, the hook-and-loop fastener 3a sewn to the outside of the connecting portion and the hook-and-loop fastener 3b attached to the upper surface of the base 2 on which the pillow body 1 is placed are fixed to each other by a hook-and-loop fastener 3c. The hook-and-loop fastener 3c, which is an elastic member, generates a restoring force that tries to return to a flat state after rolling at the connecting portion as shown in FIG. 6. For this reason, the pillow body 1 is biased to rotate in a clockwise direction in FIG. 5 and FIG. 6. That is, in addition to the bottom plate portion 10 being biased to contact the base 2, the side plate portion 20 is prevented from naturally falling to the side contacting the base 2 by the attraction force of the magnet 40 described later. Note that there are male and female hook-and-loop fasteners, but the two are relative, and which one is adopted can be changed as appropriate.

[0023] In this way, the pillow body 1 and the base 2 are connected by the female side fastener 3c, and the restoring force of the female side fastener 3c as if it were a flat plate urges the bottom plate portion 10 in the direction of contact with the base 2.

[0024] FIG. 7 is a plan view showing a state in which the pillow position is changed. The base 2 and the pillow body 1 are connected by a male side fastener 3a, a female side fastener 3c, and a male side fastener 3b. Here, when attaching the male side fastener 3b and the female side fastener 3c, it is possible to adjust the angle as appropriate.

[0025] The pillow body 1 is formed with a bottom plate 10 and a side plate 20 so that the head side is slightly open when in use. In this state, when a pair of symmetrical pillow bodies 1 are placed on the base 2, the sides of the bottom plate 10 opposite the side plate 20 face each other in a straight line. When this state is considered a general position, depending on individual differences, some people may feel that the head side is more open, while others may feel that the body side is more open.

[0026] When such individual differences occur, the attachment positions of the male side fastener 3a and female side fastener 3c on the side panel portion 20 can be left unchanged, while the opposing position of the female side fastener 3c and the male side fastener 3b on the base 2 can be shifted clockwise or counterclockwise based on the horizontal plane, thereby allowing more opening to be provided towards the head, or conversely, more opening to the body.

[0027] In this way, the relative angle between the pair of symmetrical pillow bodies 1 can be changed within a predetermined angle range.

[0028] As shown in Fig. 1, a pair of magnets 40 are attached to the sides of the bottom plate 10 of the pillow body 1, which are symmetrically opposed to each other, in a position facing each other and oriented so as to generate an attractive force. The attachment method can be changed as appropriate, and a pocket may be sewn onto the pillow body 1 side to place the magnet 40 therein. Also, one side may be an iron piece and the other only a magnet, so that they are attracted to each other by magnetic force.

[0029] Since the pair of magnets 40 are attached in the direction of attraction, the sides of the bottom plate parts 10 are stuck to each other. This stabilizes the position of the two pillow bodies 1. On the other hand, when one of the pillow bodies 1 is tilted, the two bottom plate parts 10 can be freely separated. As described below, after the side plate part 20 of the pillow body 1 is tipped outward, when it is tipped in the opposite direction again and the bottom plate parts 10 approach each other, they can be returned to their original position by the magnetic force of the pair of magnets 40. In addition, by attracting each other in the center, both bottom plate parts 10 are also attracted toward the base 2, making them less likely to slip on the base 2.

[0030] In this way, the side surfaces of the bottom plate portions 10 of the pillow bodies 1 arranged symmetrically on the left and right can be attracted to each other by magnetic force.

[0031] Next, the operation of this embodiment having the above configuration will be described. 8 to 10 are schematic diagrams showing when turning over in sleep while using a pillow. For simplification, the drawings show only a pillow body 1 and a base 2. As shown in FIG. 8, before turning over in sleep, the head 4 rests on the bottom plate portions 10 of a pair of pillow bodies 1 symmetrically arranged on the left and right.

[0032] 9 shows the state immediately after starting to turn over, with the head 4 tilted toward the side plate 20. At this point, the body may or may not be turning over. If we call the state in which only the head 4 is tilted turning over at the neck, the side plate 20 supports this turning over at the neck while remaining upright. This type of posture may occur during sleep, but by having the side plate 20 support this turning over at the neck, sleep becomes more comfortable.

[0033] 10 shows the state beyond the neck turning. When the head 4 tries to turn further from the neck turning, the bottom plate 10, which had been attracted to each other by the magnet 40, starts to separate from the other bottom plate 10 and the base 2, and the entire pillow body 1 starts to roll outward on the base 2 with the arc surface 30. Then, the outer surface of the side plate 20 comes into contact with the base 2.

[0034] As mentioned above, since the bottom plate portion 10 is thinner than the side plate portion 20, the head 4 is naturally lifted when the pillow body 1 rolls. In addition to being lifted, it can also be said that the head 4 can rotate while maintaining its natural height. Until now, when turning over in sleep, the head 4 had to maintain the same height, which forced one to assume an unnatural body shape. However, the pillow body 1 naturally rolls over, allowing one to turn over while maintaining a natural body shape. This also improves the quality of sleep.

[0035] When turning over, the process is reversed. That is, from the position shown in Figure 9, the patient returns to the neck-turning position shown in Figure 8, and then returns to the supine position shown in Figure 7. The same process is carried out when turning over in the opposite direction.

[0036] It goes without saying that the present invention is not limited to the above-mentioned embodiment. -Appropriately change and apply the mutually replaceable members and configurations disclosed in the above embodiments. · Appropriately replacing members and configurations that are not disclosed in the above embodiments but are publicly known and can be mutually substituted for the members and configurations disclosed in the above embodiments, and changing the combinations thereof for application. - Substitute members and configurations, etc. that are not disclosed in the above embodiments but that a person skilled in the art could imagine as substitutes for the members and configurations, etc. disclosed in the above embodiments based on publicly known techniques, and change and apply the combinations. is disclosed as one embodiment of the present invention.
