Description

The present invention relates to a mattress that can support the head on the pillow to an appropriate height.

Conventionally, it has been known that it is important to support the head at an appropriate height in order to obtain good sleep. If the head is not properly supported, the weight will be concentrated on the neck and shoulders, causing numbness and paralysis, and the cervical spine will be bent and the airways will be compressed, causing apnea and snoring.

At bedtime, people often turn over and take a supine or sideways posture. In the upper body, the back touches the mattress in the supine position, while the shoulders touch the mattress in the sideways position. Therefore, the position of the head in the sideways position is higher than the position of the head in the supine position, which is about 4. It is said that there is a difference of ~ 5 cm. Normally, the height of the pillow is set so that the position of the head in the supine position is an appropriate height, so that the height of the pillow is not appropriate in the sideways position.

Therefore, for example, Patent Document 1 proposes a pillow whose height can be adjusted according to the posture of a person. This pillow is equipped with a sensor that detects the posture of a sleeping person and a pump means that injects fluid into the pillow by pumping means, and injects fluid into the pillow according to the posture of the person to adjust the height of the pillow. I'm adjusting.

Japanese Unexamined Patent Publication No. 10-11269

However, the pillow described in Patent Document 1 has a problem that sleeping is hindered by the operation sound of the pump means and the sound of fluid flowing in the immediate vicinity of the head during sleeping. For this reason, it has been desired to provide a means for adjusting the height of the head with a mattress instead of a pillow.

The present invention has been made by paying attention to the above-mentioned problems, and an object of the present invention is to provide a mattress in which the head on the pillow is supported at an appropriate height even when the head is in a sideways posture while sleeping.

The mattress according to the present invention is entirely made of a cushioning material, and has a shoulder support portion having a higher compression rate than other portions near one end in the length direction, and the shoulder support portions have a plurality of parallel parallel portions having an open upper surface. A groove and at least one ridge formed between adjacent grooves.

The height of the pillow is set so that the head is positioned at an appropriate height when lying on its back, but when it is turned sideways and the shoulder is placed on the ridge of the shoulder support, the ridge is placed. Is compressed and deformed so as to be expanded into the grooves on both sides by pressing, so that the shoulder sinks into the shoulder support portion, and the distance between the position of the shoulder and the upper surface of the pillow becomes relatively long. Therefore, the head is supported at an appropriate height.
As described above, according to the present invention, the head on the pillow is supported at an appropriate height regardless of whether the posture is supine or sideways at bedtime.
Furthermore, by supporting the head at an appropriate height, the cervical spine is kept almost horizontal in both supine and sideways postures, so the airway does not become narrowed or compressed, and there is no apnea. Can prevent breathing and snoring.

Further, when the groove is set to a width and a depth that can be expanded to the extent that the arm can be inserted, the shoulder can be further submerged in the mattress by inserting the arm into the groove.

In a preferred embodiment, the ridge is a strip with a straight plan view.

In the above embodiment, the ridges may be formed along the width direction.

In another embodiment, the ridge may be V-shaped in plan view and have a bent portion.

In the above embodiment, the bent portion may be located at the central portion in the width direction.

In a preferred embodiment, the grooves and ridges are formed over the entire width.

The ridge may have a cross-sectional shape orthogonal to the length direction of any of a rectangular shape, a trapezoidal shape, an inverted trapezoidal shape, and a convex curved surface shape.

The ridge may be a cushioning material having a higher compression rate than other parts.

According to the mattress of the present invention, the head on the pillow is supported at an appropriate height regardless of whether the posture is supine or sideways at bedtime.

Embodiments of the present invention will be described with reference to the drawings.
1 to 3 show the mattress 10 according to the embodiment of the present invention. The mattress 10 is entirely made of cushioning materials 31a to 31c, and in order from one end side in the length direction X, the head support portion 11 that supports the head, the shoulder support portion 12 that supports the shoulders, and the back, waist, and so on. It is divided into a waist leg support portion 13 that supports the legs.

The mattress 10 may be any one that is laid under the body when the person P lies down, and includes a mattress and the like.

The shoulder support portion 12 is located near one end of the mattress 10 in the length direction X, and the shoulder support portion 12 is continuously formed on the head support portion 11 of the mattress 10.

Assuming that the length X of the mattress 10 in the length direction is L, the length L2 of the head support portion 11 in the length direction X is L / 6 or more and L / 3 or less. The length L1 of the shoulder support portion 12 in the length direction X is preferably L / 30 or more and L / 4 or less, and in the present embodiment, the length is about L / 5.

In the present embodiment, assuming that the length L of the single and double mattresses 10 in the length direction X is 200 cm, the length L2 of the head support portion 11 in the length direction X is 40 cm, and the shoulder support portion 12 has a length L2 of 40 cm. The length L1 in the length direction X is 40 cm, and the length L3 in the length direction X of the waist leg support portion 13 is 120 cm.

The head support portion 11 is formed by covering a cushion material 31a having a rectangular shape when viewed from a plane with a bag-shaped cover 32a. Further, the waist leg support portion 13 is formed by covering a cushion material 31c having a rectangular shape when viewed from a plane with a bag-shaped cover 32c. The material of the cushion materials 31a and 31c is, for example, urethane foam, but may be composed of synthetic fibers such as polyester, acrylic, and polypropylene.

The shoulder support portion 12 includes a plurality of parallel grooves 20 having an open upper surface and at least one ridge 21 formed between the adjacent grooves 20. In the present embodiment, the five grooves 20 and the four ridges 21 are provided between the grooves 20, but the number of the grooves 20 and the ridges 21 is not limited. The ridge 21 has a straight strip shape in a plan view and is formed over the entire width of the mattress 10. The ridge 21 has a rectangular cross-sectional shape orthogonal to the length direction X. The ridge 21 and the groove 20 are formed by erection of a rectangular parallelepiped cushion material 31b covered with a bag-shaped cover 32b at intervals. The cushion material 31b of the ridge 21 is made of the same material as the cushion materials 31a and 31c of the head support portion 11 and the waist leg support portion 13.

The shoulder support portion 12 has a higher compressibility than the head support portion 11 and the waist leg support portion 13 and is easily deformed by compression. This is because the shoulder support portion 12 is formed of the ridge 21 and the groove 20. This is because when a force is applied to the ridge 21 from above, the cushion material 31b of the ridge 21 is compressed and deformed so as to be expanded into the groove 20.

If the width L5 of the ridge 21 (the length of the mattress 10 in the length direction X) is small and the width L4 of the groove 20 (the length of the mattress 10 in the length direction X) is wide, the ridge 21 is easily compressed and deformed. The shoulders tend to sink. The width L5 of the ridge 21 and the width L4 of the groove 20 are selected according to the desired lowering width of the shoulder position. The width L5 of the ridge 21 is preferably 3 cm or more and 15 cm or less, more preferably 7 cm or more and 8 cm or less, and is about 7.5 cm in this embodiment. The width L4 of the groove 20 is preferably a width that can be expanded to the extent that the arm of the person P can be pushed in, preferably 1 cm or more and 3 cm or less, and is about 2 cm in the present embodiment.
Further, the depth L6 of the groove 20 is preferably a depth such that the arm of the person P can enter, preferably 3 cm or more and 10 cm or less, and is 7 cm in the present embodiment.

The mattress 10 is manufactured by sewing the lower surfaces of the covers 32a, 32b, and 32c of the ridges 21 of the head support portion 11, the waist leg support portion 13, and the shoulder support portion 12 on the upper surface of one piece of fabric 30. To. The manufacturing method is not limited to this, and for example, a groove 20 and a ridge 21 are formed at predetermined positions on the upper surface of a flat plate-shaped cushion material having a desired size, and a cover having a shape along the outer shape of the cushion material is provided. By covering it, the mattress 10 may be configured.

4 (A) and 4 (B) are explanatory views showing the mattress 10 of the present embodiment when the person P is in the supine position and the sideways position. FIG. 4A shows the person P in the supine position, and the compression ratio of the shoulder support portion 12 is the head because the back pressure is small enough to contact the ridge 21 of the shoulder support portion 12 of the mattress 10. Even if it is larger than the support portion 11 and the waist leg support portion 13, the back and shoulders do not sink so much into the shoulder support portion 12, and the head is supported by the pillow 40 at an appropriate height h1. FIG. 4B shows the sideways posture of the person P, and when the shoulder is placed on the ridge 21 of the shoulder support portion 12, the ridge 21 is greatly compressed and deformed due to the grooves 20 on both sides thereof. , The shoulder sinks into the shoulder support portion 12. Therefore, even if the pillow 40 has the same height h1 as in the supine position, the head is supported at an appropriate height.

As described above, according to the mattress 10 of the present embodiment, the head on the pillow 40 is supported at an appropriate height in either the supine posture or the sideways posture.

FIG. 8 shows a sideways posture in which the arm is placed in the expanded groove 20. According to this posture, the degree of sinking of the shoulders can be further reduced, and the head can be supported at an appropriate height. Further, when a child, a partner, a pet or the like sleeping on the same mattress 10 puts his / her arm in the groove 20 and puts his / her arm on the arm pillow, the weight of the child or the like is not applied to the arm and the arm does not become numb.

The present invention is not limited to the above embodiment. For example, as shown in FIG. 5, the groove 20 and the ridge 21 may be formed so as to have a V-shaped shape in a plan view and have bent portions 20a and 21a. In this case, the bent portions 20a and 21a may be located at the central portion in the width direction Y. According to this configuration, the arm can be extended diagonally upward and put into the groove 20 regardless of the sideways posture in either the left or right direction at bedtime.

Further, as shown in FIG. 6, the ridge 21 and the groove 20 may not be formed on both end sides of the mattress 10 in the width direction Y, but may be formed only in the central portion.

Further, in the above embodiment, as shown in FIG. 7, the ridge 21 has a trapezoidal shape (FIG. 7 (A)) and an inverted trapezoidal shape (FIG. 7 (B)) having a cross-sectional shape orthogonal to the length direction X. ) Or a convex curved surface (FIG. 7 (C)). Further, in the same mattress 10, the cross-sectional shapes of the plurality of ridges 21 may be different from each other. The convex curved surface includes a shape in which only the upper end portion of the rectangular shape is rounded, and a semicircular shape or a semi-elliptical shape in which the upper end is convex.

Further, in the above embodiment, the ridge 21 may use a cushioning material having a higher compression rate than the head support portion 11 and the waist leg support portion 13. Since the ridge 21 is easily compressed and deformed, the shoulder position can be further lowered.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
