To provide a pillow that facilitates deep breathing and rolling over when a person sleeps on his back or takes a rest, and allows a person to have a comfortable and restful sleep.

In Patent Document 1, as a structure of a pillow that meets sleep needs, a flexible pillow is provided in which a recessed portion 113 is formed in the central portion of a central unit 11 and side units 12 forming recessed portions are formed on both sides of the central unit. It discloses that an upper body 2 and a harder body 1 are vertically stacked and integrally formed.
However, with such a pillow, the head and back are in a horizontal state, so it is not possible to turn over smoothly. In addition, when a person continues to lie sideways for a long period of time, the waist sinks and the face is locally supported.

In addition, the pillow of Patent Document 2 is placed on the upper surface of the pillow made of a material with appropriate elasticity in order to make rolling over smoothly. It is a parallel pillow.
However, in the supine position, the shoulders are supported by the bed, which increases the load on the shoulders.

In addition, the pillow of Patent Document 3 has a plurality of middle pillow pads 2, 4, 6 and a plurality of top pads 3, 5, 7, 8 detachably placed on a horizontally long mat with a flat bottom surface. There is a pillow body 1 in which the pillows are stacked with the central part depressed. By freely transforming each pad and changing the size, thickness, length, and thickness, it is possible to construct a large and small variety of pillows.
Since this pillow is constructed by stacking a large number of mats, it is unsanitary because it is easy for dust to adhere to it and it takes time and effort to wash it. In addition, since the air permeability of the head is poor, the head becomes stuffy and hot, making it impossible to sleep soundly. Also, if you sleep on your back, both shoulders will rise, making it difficult to turn over, and your chest will be squeezed from both sides, making breathing shallow. Therefore, you cannot get a good night's sleep.

Further, the pillow of Patent Document 4 has a pillow body 1 having a hollow portion 4 in the center and a flat pad portion 7 containing an inner material 2 placed on the upper surface of the pillow body 1 to form a two-ply stack.
In this type of pillow, the pillow body 1 and the pad part 7 are layered in two, but the air permeability of the part supporting the head with the hollow part 4 is poor, so the head becomes hot and it is not possible to take a sufficient sleep. . Moreover, nothing is disclosed about facilitating rolling over.

The first pillow main body 2 is made of synthetic fibers, and the pillow portion 7 and the pillow base 8 are integrally molded in a T shape in plan view. The synthetic fibers used in this product are polyetherester-based synthetic fibers that form a three-dimensionally intertwined cushioning material that is resistant to sagging, has high recovery after compression, and is washable with excellent breathability. . In addition, it has excellent water permeability and durability, and has the effect of suppressing the growth of bacteria, so it can be used for mattresses and pillows to provide a comfortable sleeping experience. A product using this synthetic fiber is Breath Air (registered trademark of Toyobo Co., Ltd.).

The pillow portion 7 has a horizontal length longer than a vertical length, and has a U-shaped concave portion 10 formed in the center with an open portion 9 whose upper end is open. When the head 11 is placed on the recess 10, ventilation from the open part 9 prevents the head from becoming hotter than the head supported by the recess which is not open, so that the user can sleep soundly.
Both sides of the concave portion 10 are provided on a flat surface 12 having a length capable of supporting the head 11 when the person rolls over from the supine posture. A slope 14 rising to the left and a slope 15 rising to the right are formed toward the side end.

With this configuration, the head 11 can be smoothly moved by the slope 14 and the head 11 can be prevented from falling from the pillow part 7 when the body 16 is put in a sideways posture by rolling over. Conversely, even when returning from the sideways posture to the supine posture, the head 11 can be smoothly moved to the flat surface 12 by the slope 14 .

The width b of the pillow base 8 is narrower than the width a of the pillow portion 7 so as to be long in the vertical direction, and the pillow portion 7 is arranged in the central portion thereof. Spaces 29 can be formed on both left and right sides of the pillow 7, so that when the user is in a supine posture, the feeling of pressure on the chest is eliminated by opening both arms laterally, so that the user can take a deep breath and eliminate the feeling of tension. be able to.

Since the connecting portion 30 between the pillow base 8 and the pillow portion 7 is widened from the pillow base 8 toward the pillow portion 7, the durability against the pressure applied by the lying body 16 can be enhanced.
The second pillow body 3 is formed to have the same outer shape and size as the first pillow body 2, and has a pillow part 17 and a pillow base 18 formed in a T shape in plan view and a filling to be accommodated in the inner cover 4. 19 are provided. The middle cover 4 is formed so that its horizontal length is longer than its vertical length, and the width c of the pillow base 18 is narrower than the width b of the pillow base 8 in the first pillow body 2 .

The inner cover 4 forms an opening 20, and an inner cover opening/closing member 21 for opening and closing the opening 20 is provided along the opening 20 (the upper end of the pillow portion 17 in the embodiment). In addition, although the inner cover opening/closing member 21 uses a fastener in the embodiment, it is not limited to a fastener as long as it can be opened and closed such as a magic tape or a string. In addition, since the inner cover 4 is made of synthetic fibers, it dries quickly and is effective as a cover.

By operating the inner cover opening/closing tool 21, the filling 19 made of synthetic polyester polyester is stuffed downward from the opening 20 along the folding line 24 of the pillow part 17, and the inner cover opening/closing tool 21 is operated to fill the opening. A sewn part 22 is provided so that the front surface and the back surface of the inner cover 4 are sewed together after the cover 20 is closed.
The sewn parts 22 are sewn at predetermined intervals from the pillow part 17 to the pillow base 18 in the central part 23 in the lateral direction of the second pillow body 3 .

Moreover, both side portions of the sewn portion 22 provided on the pillow portion 17 are provided with sewn portions 22 which are sewn at predetermined intervals in the vertical direction. By arranging the sewn portions 22 provided on the pillow portion 17 in a straight line in the vertical direction across the folding line 24, the pillow portion 17 can be smoothly folded toward the pillow base 18.例文帳に追加

As a result, the movement of the filling 19 accommodated in the inner cover 4 is suppressed to prevent it from losing its shape, and it can be formed into a flat shape by pressing in the thickness direction, so that the second pillow body 3 can be laid on the back or sideways. You can keep your body in a stable position. Further, the connecting portion 30 between the pillow 18 and the pillow portion 17 of the inner cover 4 is widened from the pillow 18 toward the pillow portion 17 to increase the strength.

The inner cover 4 has a loop-shaped shift prevention member 25 wrapped around the corners of the folded pillow portion 17 attached to each corner above the pillow portion 17 . The anti-slipping tool 25 may be a string, tape, rubber or the like as long as it does not unravel the overlapped corners.

The base housing bag 5 is made of synthetic polyester polyester and formed into a bag shape with one end open, and houses the bases of the first pillow body 2 and the second pillow body 3 that are stacked. The base housing bag 5 is made of a material that adheres tightly so that the bases do not slip out when the first pillow body 2 and the second pillow body 3 are taken out from the pillow cover 6 . A string, rubber, or the like attached to the base receiving opening 26 may be attached or used to prevent disengagement.

The pillow cover 6 is made of recycled fiber and formed into a T-shaped bag in a plan view similar to the outer shape of the first pillow body 2 and the second pillow body 3. - 特許庁The pillow cover 6 has a size to restrain the movement of the first pillow body 2 and the second pillow body 3 when the first pillow body 2 and the second pillow body 3 are accommodated from the pillow cover opening 27 provided at the upper end. is formed in

As the pillow cover opening/closing tool 28 for opening and closing the pillow cover opening 27, many means such as fasteners, magic tapes, and strings are conceivable, but it is convenient to use the fastener. The pillow cover 6 is made of lyocell, which is beautiful , soft , eco-friendly and body-friendly.

(Example in which the second pillow body 3 is arranged on the surface of the first pillow body 2)
After the second pillow body 3 is placed on the first pillow body 2, the lower end of the pillow part 17 without filling is positioned several centimeters from the lower end of the pillow part 7 located on the lower side of the pillow part 17 (example). 4 centimeters), fold it toward the pillow 18 with the folding line 24 as the center. By folding in this way, it is possible to prevent the neck from drooping significantly when the user rolls over. Further, by sandwiching the corners of the folded pillow portion 17 with the anti-slipping tool 25, it is possible to prevent the overlapped portion of the pillow portion 17 from coming apart.

The bases of the first pillow body 2 and the second pillow body 3 are housed in the base housing bag 5. - 特許庁In this state, the base housing bag 5, the first pillow body 2, and the second pillow body 3 are pushed into the pillow cover 6 from the pillow cover opening 27 in that order. After confirming that the second pillow body 3 is in a predetermined position on the first pillow body 2 visually or by using a device, the pillow cover opening/closing member 28 is operated to close the pillow cover opening 27 .

After that, if the shape is corrected by manual work or machine work, etc., the second pillow body 3 is placed on the surface of the first pillow body 2 to complete a pillow of a desired shape.

(Example in which the second pillow body 3 is arranged on the back side of the first pillow body 2 )
As described above, the second pillow body 3 with its corners sandwiched by the shift prevention tool 25 is placed on the back side of the first pillow body 2, and the bases of both pillow bodies are housed in the base housing bag 5. In this state, the base housing bag 5, the first pillow body 2, and the second pillow body 3 are pushed into the pillow cover 6 from the pillow cover opening 27 in that order. As in the case of arranging the second pillow body 3 on the surface of the first pillow body 2, the second pillow body 3 is in a predetermined position on the first pillow body 2 visually or by using a device (not shown). After confirmation, the pillow cover opening/closing tool 28 is operated to close the pillow cover opening 27.例文帳に追加

By correcting the pillow portion 17 so as to be flat before closing the pillow cover opening 27, subsequent work can be facilitated. After that, if the shape is corrected by manual work or machine work, etc., the second pillow body 3 is placed on the back surface of the first pillow body 2 to complete a pillow of a desired shape.

In both the case where the second pillow body 3 is arranged on the surface of the first pillow body 2 and the case where the second pillow body 3 is arranged on the back side of the first pillow body 2 , the recessed portion 10 of the pillow portion 7 is in a sleeping posture. Since a certain head 11 is supported, and the pillows 8 and 18 support the back and waist, the head 11, the neck, and the center of the back can be lifted to disperse the body pressure. As a result, the burden on the shoulders and lower back can be reduced, and because the chest can be stretched, breathing becomes larger and a good night's sleep can be achieved.

Also, when turning over and turning sideways, the head 11 can smoothly move from the concave portion 10 to an adjacent place in the pillow portion 7, and the body 16 can also smoothly move to the space portion 29 adjacent to the pillows 8 and 18. can do. In this movement, the force of the body 16, the restoring force of the elastic material of the first pillow body 2, and the narrow pillow base 18 of the second pillow body 3 combine to make the movement smooth. It should be noted that the posture can be returned smoothly by the same function when returning from the sideways posture to the supine posture.

In the sideways posture, the head 11 moves to a position adjacent to the recess and becomes higher than the recess 10, and the shoulders sink into the space 29 on the side of the pillows 8 and 18, thereby reducing the burden on the shoulders and the chest. Since the pressure on the body is reduced and breathing is easy, a comfortable sleep can be obtained, resulting in a good wake-up time and a refreshed mood.
The concave portion 10 of the first pillow body 2 is formed in a U-shape with an open upper portion to improve the air permeability to the head 11 through the open portion 9, so that the head becomes hot and the discomfort caused by the generation of stuffiness is reduced. and get a good night's sleep.

By arranging the second pillow body 3 on the front surface or the back surface of the first pillow body 2, the user can freely select the use of a pillow with a smooth touch or a pillow with a slightly rough touch. Therefore, it is possible to select a pillow that suits the mood of the day, etc., thereby improving convenience. In addition, since the first pillow body 2 uses chemical fibers and the second pillow body 3 uses regenerated fibers, the pillow does not lose its shape, has good air permeability, and is good for health.

By forming the first pillow body 2 with a cushioning material that is three-dimensionally entwined with resin fibers, the body pressure is dispersed because the body 16 is supported not by a surface but by many lines and points. Moreover, the pressure on the head 11 placed on the recess 10 can be reduced. Further, since it has high air permeability, it does not get stuffy easily, and can be easily washed by removing it from the pillow cover 6. - 特許庁In addition, since there is a recovery action to return to the original shape from the deformed state, it is possible to assist rolling over to the back and sideways.

In addition, since the second pillow body 3 can be easily removed from the pillow cover 6 by storing synthetic fibers in the inner cover, it can be easily replaced.
In addition, since the anti-slipping tool 25 for sandwiching the corners of the folded pillow part is provided on the pillow part 17 of the inner cover 4, the second pillow body 3 is prevented from slipping or coming apart when the second pillow body 3 is put into or taken out of the pillow cover 6. - 特許庁can prevent This makes it easy to put the second pillow body 3 and the first pillow body 2 into and out of the pillow cover 6.例文帳に追加
