Description

The present invention relates to pillows.

There is a pillow in which a bag body made of a side cloth is filled with a stuffing (a resin short pipe, beads, granular cotton, buckwheat husks, feathers, urethane foam, etc.). In this pillow, when the user's head is placed on the upper surface, the padding inside the bag is deformed and supported so as to wrap the head.
Since the head and cheeks of the user come into direct contact with the upper surface of the pillow, it is an important factor that influences sleeping comfort. For example, if the side fabric is pulled when the user's head is placed on the pillow top surface, the user feels as if he/she is sleeping on a hard object, which makes the user feel uncomfortable. ..
In order to suppress the tension of the side cloth on the upper surface of the pillow, it is conceivable that the pillow is divided into a right side portion, a central portion, and a left side portion, and each portion is independently deformable.

For example, in Patent Document 1, a bag body in which each independent space for the central low pillow portion, the right high pillow portion, and the left high pillow portion is formed, a cloth stored in the central independent space of the bag body, and And a padding for filling the independent space of the pillow. In the bag body of the pillow, the partition between the central independent space and the left and right independent spaces is formed by stitching the upper cloth and the lower cloth on the lower surface of the bag along the depth direction. .. In other words, in the pillow, the central low pillow part and the right high pillow part, and the central low pillow part and the left high pillow part are connected over the entire length in the depth direction on the lower surface of the bag (pillow). There is.

In the pillow of Patent Document 1, when the user's head is placed on the upper surface of the central low pillow portion, each high pillow portion having a height higher than that of the central low pillow portion is located on the left and right sides of the head, and the air passage is provided. Since the space is narrowed, the air permeability around the head may be impaired. When the air permeability around the head is impaired, heat and moisture are likely to be trapped, which makes the sleep uncomfortable, and the number of times of rolling over is increased, so that it is difficult to obtain deep sleep.
In addition, in the pillow, when the user who has the head placed on the central low pillow portion rolls over, the head must be lifted to each high pillow portion that is higher than the central low pillow portion. The burden on the neck (for example, muscle tension) that supports the person becomes large. Further, in the pillow, since the central low pillow portion and each high pillow portion are connected over the entire length in the depth direction on the lower surface of the pillow, the position of the head of the user when the user rolls over. May be displaced from the center of the upper surface of the high pillow portion, which may give a discomfort to the head of the user. Since the user who is sleeping is unconscious, the burden on the neck and discomfort of the head accompanying turning over are perceived after waking up, which may be a cause of pain and drowsiness.
The present invention has been made in view of such circumstances, and an object thereof is to improve the breathability around the head and to improve the fit of the head when turning over.

In order to solve the above problems, the pillow according to the present invention includes a main pillow unit that is deformed by a user's head resting on it, and the main pillow unit is arranged on each of one side and the other side in the width direction of the main pillow unit. A pair of sub-pillow units that are deformed when the head is placed, and a connecting portion that openably and closably connects the main pillow unit and end portions of the respective sub-pillow units on the body side of the user in a close state. , the connecting portion, when said opens the respective sub pillow unit is manufactured to the main pillow unit the are stitched to each sub pillow unit, and with respect to said main pillow unit by the fabric, the main A space is formed between the pillow unit and each of the sub pillow units .

According to the present invention, it is possible to improve the ventilation around the head and to improve the fit of the head when turning over.

<Outline of pillow>
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, the outline of the pillow will be described. 1 to 4 are a front view, a plan view, a bottom view, and a rear view of the pillow 1 according to the first embodiment, respectively. FIG. 5A is a diagram illustrating a usage state of the pillow 1, and FIG. 5B is a diagram illustrating a positional relationship between the head HD and the units 10, 20, and 30 when hitting over.
In addition, in the following description, the left and right of the pillow 1 are determined based on the posture of the user HU (see FIG. 5) in the supine position. Specifically, the side where the left shoulder of the user HU is located when lying on the back is called the left side of the pillow 1, and the side where the right shoulder is located is called the right side of the pillow 1. Further, as shown in FIGS. 1 and 2, the direction connecting the left and right sides of the pillow 1 is called the width direction of the pillow 1, and the direction connecting the body of the user HU and the crown is called the depth direction of the pillow 1. Further, the surface of the pillow 1 on the body side of the user HU is referred to as the front surface.

As shown in FIGS. 1 to 4, the pillow 1 includes a middle unit 10 (main pillow unit), a right unit 20 (one side pillow unit) located on the right side (one side in the width direction) of the middle unit 10, The left unit 30 (the other side pillow unit) located on the left side (the other side in the width direction) of the middle unit 10 and the middle unit 10 and the right unit 20 are used as the body side edge (body side end) of the user HU. And a right connection part 41 (one connection part) openably and closably connected, and a left connection in which the middle unit 10 and the left unit 30 are openably and closably connected at a body side edge of the user HU (body side end). And a part 42 (the other connecting part). The middle unit 10, the right unit 20, and the left unit 30 each have a rectangular parallelepiped shape.
As shown in FIGS. 5A and 5B, the middle unit 10 is a portion on which the user HU in the supine posture places the head HD, and the right unit 20 is a user on which the head HD is placed on the middle unit 10. The head HD rests when the HU rolls over to the right, and the left unit 30 is the portion where the head HD rests when the user HU who has the head HD on the middle unit 10 rolls over to the left. Is. Each of the units 10, 20 and 30 is deformed so as to wrap the head HD with the head HD of the user HU placed on the upper surface, and distributes the pressing force to the head HD.
Each of the connecting portions 41, 42 is made of a flexible cloth, connects adjacent units, and when the head HD of the user HU is placed on any unit, is deformed according to the deformation of the unit. To do.

As shown in FIGS. 1 to 5, each of the units 10, 20, and 30 can be independently deformed because the edges are cut off at portions other than the right connecting portion 41 and the left connecting portion 42, and thus the user HU. Even if the unit on which the head HD is mounted is deformed, other units are hardly affected by this deformation. As a result, only the unit on which the head HD is placed is deformed so as to wrap the head HD, so that the sleeping comfort can be improved.
In addition, as shown in FIGS. 5A and 5B, in this pillow 1, the units 10, 20, and 30 are opened in a fan shape around the connecting portions 41 and 42, so that a space is provided between the units. A place (right space SP1, left space SP2) is formed. Since the air permeability around the head HD is improved by each of the cavities SP1 and SP2, heat and humidity are less likely to be trapped, and the sleeping comfort can be improved.
Further, in this pillow 1, when the head HD of the user HU moves to the adjacent unit as the user rolls over, the position of the head unit HD of the destination unit shifts. By repeatedly turning over, the units 10, 20, 30 settle in positions suitable for the user HU, so that the fit of the head HD at the time of turning over can be improved.

<About the first embodiment>
Hereinafter, the pillow 1 of the first embodiment will be described in detail.
As shown in FIGS. 1 to 4, the pillow 1 includes a middle unit 10, a right unit 20, a left unit 30, a right connecting portion 41, and a left connecting portion 42.
The middle unit 10 is formed by filling a filling (not shown) in a middle bag body 11 formed by sewing a flexible side cloth into a rectangular parallelepiped shape, and is deformed when the head HD of the user HU is placed. As the side fabric forming the inner bag body 11, for example, a cloth made of a chemical fiber such as polyester or polyethylene, or a cloth made of a natural fiber such as cotton, hemp, and silk can be used. In this embodiment, polyester cloth is used. The padding to be filled in the inner bag body 11 is selected in consideration of breathability, hygroscopicity, moisture release, cushioning property, supportability and the like, and for example, resin short pipe, beads, granular cotton, buckwheat hulls, feathers, And urethane foam can be used. In this embodiment, a resin short pipe is used.

The size of the inner bag body 11 can be appropriately determined, but in this embodiment, the width W1 is 18 cm, the depth L1 is 18 cm, and the height H1 is 15 cm.
Since the middle unit 10 is for the user HU in the supine position to put the head HD, the width (width W1 of the middle bag 11) is such that when the user HU rolls over the head HD. It is required that the size is such that it can be moved to the right unit 20 and the left unit 30 without trouble. If the width W1 of the middle unit 10 is made too narrow, the middle unit 10 becomes difficult to be deformed, and the user HU feels as if he/she is sleeping on a hard object. From these viewpoints, it is desirable that the width W1 of the middle unit 10 is set to be 1.5 times or more and 2 times or less the neck width of the user HU.
For example, the average neck width of a woman is about 10 cm (corresponding to 32 cm around the neck), and the average neck width of a man is about 11.5 cm (corresponding to about 36 cm around the neck). Therefore, by setting the width W1 of the middle unit 10 in the range of 15 cm (1.5 times the neck width of a woman) to 23 cm (twice the neck width of a man), the head HD is placed on the middle unit 10. When the user HU in the recumbent posture rolls over, the head HD can be positioned on the upper surface of the adjacent unit 20, 30.

The depth of the middle unit 10 (the length L1 in the depth direction of the middle bag 11) supports the heat from the top of the head to support from the neck to the back of the user HU and does not support the top of the head. The length is fixed.
In an adult of average size, the distance from the top of the occipital region (the most protruding part) to the base of the neck (the boundary with the shoulder) is 18 cm to 25 cm. Therefore, by setting the depth L1 of the middle unit 10 to 18 cm, the top of the head is not supported by the middle unit 10, and the heat of the top of the head is easily released into the air. As a result, it becomes difficult for the pillow 1 to retain heat, and the sleeping comfort is improved.
The depth L1 of the middle unit 10 is not limited to 18 cm. For example, even if the depth L1 is set in the range of 15 cm to 28 cm with some allowance (±3 cm) based on the average distance (18 cm to 25 cm) from the top of the occipital region to the base of the neck. The same effect can be obtained.

The height of the middle unit 10 can be adjusted by the amount of the filling material filled in the middle bag 11, and the maximum value is the height H1 of the middle bag 11. Further, the hardness of the middle unit 10 can be adjusted by the type of filling and the filling amount.
As shown in FIG. 2 and FIG. 3, the partition cloth 12 is provided on the inner peripheral surface of the inner bag body 11 at an intermediate position in the depth direction (for example, a position 9 cm away from the front of the inner bag body 11 toward the top of the head). The outer peripheral edge of is sewn, and the first small chamber 10A and the second small chamber 10B that can be filled with the filling are formed inside the inner bag body 11. In the present embodiment, the first small chamber 10A is located on the body side in the depth direction of the middle unit 10, and the second small chamber 10B is located on the crown side in the depth direction.
As shown in FIG. 3 and FIG. 6A, the first small chamber 10A side on the bottom surface of the middle unit 10 is provided with a first middle opening 13A that can be opened and closed by a first medium line fastener 14A, and the second small chamber 10B side. Is provided with a second middle opening 13B that can be opened and closed by a second middle wire fastener 14B. As shown in FIG. 6B, one end of a tubular first middle tubular cloth 15A is sewn to the first middle opening 13A, and the first middle tubular cloth 15A is communicated with the first small chamber 10A. .. One end of a tubular second middle tubular cloth 15B is sewn to the second middle opening 13B, and the second middle tubular cloth 15B is communicated with the second small chamber 10B.

As shown in FIG. 3 and FIGS. 6A and 6B, the first middle opening 13A is a linear cut along the width direction of the pillow 1, and fills the first small chamber 10A with a filling, It is used when the filling is taken out from the first small chamber 10A. The first middle tubular cloth 15A assists the stuffing from falling when the stuffing is taken in and out of the first small chamber 10A. The first middle tubular cloth 15A is stored in the first small chamber 10A when the filling is not taken in and out, and is pulled out of the first middle opening 13A when the filling is taken in and out.
Similarly, the second middle opening 13B is a linear cut along the width direction of the pillow 1, and is used when filling the second small chamber 10B with a filling or removing it from the second small chamber 10B. The second middle tubular cloth 15B assists the stuffing from falling when the stuffing is taken in and out of the second small chamber 10B. The second middle tubular cloth 15B is stored in the second small chamber 10B when the filling is not taken in and out, and is drawn out of the second middle opening 13B when the filling is taken in and out.

Since the first small chamber 10A and the second small chamber 10B are independent spaces from each other, the type and filling amount of the filling can be determined for each. For example, the first small chamber 10A on the torso side is filled with an amount of padding necessary to support the neck of the user HU, and the second small chamber 10B on the parietal side has a smaller amount than the first small chamber 10A. By filling the padding, it is possible to easily deform the shape of the back of the head. Further, the first small chamber 10A may be filled with granular cotton in place of the resin short pipe to improve the flexibility of the contact surface with the neck.
