Description

The present invention relates to a pillow with a mat.

With respect to this type of matted pillow, for example, a head support having an elastic head having a predetermined height and a cervical spine lower in height than the head support are placed. An elastic cervical spine support and an elastic cervical spine support that is even lower in height than the cervical spine support and on which the upper thoracic spine is placed are provided in order along the horizontal direction, and the head is provided. The side cross-sectional shape of the entire pillow composed of the part support, the cervical spine support, and the thoracic spine support is substantially triangular, and is recessed downward between the head support and the cervical spine support. A pillow having a groove of 1 has been proposed (see, for example, Patent Document 1).

The pillow of Patent Document 1 describes that the burden on the cervical spine of the user is reduced and the upper cervical spine becomes easy to move, so that the balance of the body is maintained at bedtime and a relaxed sleep can be obtained. There is.

Further, a first support portion that supports the user's head, a second support portion that supports the neck portion, and a third support portion that supports the shoulders and chest are provided, and the second support portion and the first support portion are provided. The pillow is made of a high-resilience urethane material that is harder in the order of the support part and the third support part, and the end on the chest side of the third support part has an inclination angle of 10 to 20 degrees from the horizontal plane. Has also been proposed (see, for example, Patent Document 2).

The pillow of Patent Document 2 is easy for the user because it supports not only the user's head and neck but also the entire shoulder and chest and eases the burden on the neck (cervical spine) while adopting a simple shape. Moreover, it is stated that a comfortable sleep can be obtained.

Japanese Patent No. 5596637 Japanese Unexamined Patent Publication No. 2019-110966

However, since the pillows described in Patent Documents 1 and 2 support only the upper thoracic spine or the chest of the user, almost the entire spine extending to the cervical spine, the thoracic spine, and the lumbar spine is loose, smooth, and natural in lateral view. It is hard to be curved. As a result, the burden on the user's cervical spine cannot be sufficiently reduced, which may give unnecessary oppressive feeling to the trachea and organs of the upper body such as the esophagus, lungs, stomach, and heart. There was a problem that it was difficult to turn over to the sideways sideways smoothly and naturally.

The present invention solves the above-mentioned problems, supports almost the entire spine of the user at bedtime in a loose, smooth and natural curved shape, can sufficiently reduce the burden on the cervical spine, and can be applied to the trachea and organs of the upper body. On the other hand, we provide a pillow with a mat that makes it difficult to give an unnecessary feeling of oppression and allows you to turn over smoothly and naturally.

Hereinafter, embodiments for carrying out the present invention will be described.

In addition, "polyurethane" in this specification represents "foamed polyurethane" unless otherwise specified. In addition, the hard polyurethane layer is made of low-resilience polyurethane, high-breathability polyurethane, or high-density / high-resilience polyurethane having a density of 25 kg / m3 or more, and the portion other than the hard polyurethane layer has a density of 20 kg / m3. It consists of the following so-called soft polyurethane. In the following, polyurethane foam is simply abbreviated as urethane.

FIG. 1 is a perspective view showing a pillow with a mat 1 according to an embodiment of the present invention, and FIG. 2 is a side view. Further, in the drawing, the left-right direction in the figure is the height direction (vertical direction) of the user H, and the front-back direction in the figure is the width direction.

As shown in FIGS. 1 and 2, the matted pillow 1 includes a pillow portion 3 that supports a part 300a of the head H1 and the neck H2 of the user H, and a waist portion from the neck H2 of the user H to the chest H3. It is composed of a sheet-shaped mat portion 2 that supports the other portion 300b up to the vicinity of H4. Further, the portion supporting the head H1 to the neck H2 of the user H is referred to as the head support portion 10a, and the portion supporting the lumbar region H4 from the neck H2 via the chest H3 is referred to as the body support portion 10b.

The boundary between the head support portion 10a and the body support portion 10b is not specified at a definite position, and it is a general form that the ranges of the two overlap in part. This point also changes depending on the height and physique of the user H. Further, the vicinity of the lumbar region H4 includes not only the case of reaching the lumbar region H4 (lumbar vertebrae) of the user H but also the case of reaching the lowermost portion of the lumbar vertebrae located immediately before the lumbar region H4. This point also changes depending on the height and physique of the user H.

The head support portion 10a is located in a vertical cross section between the upper head ridge 4, the cervical side ridge 5, and the head upper ridge 4 and the cervical ridge 5, and faces downward. It has a concave groove portion 6 for the head that is loosely recessed. The head groove portion 6 is arranged along the entire length in the width direction of the head support portion 10a, and supports the occipital region or the temporal region of the user H.

Incidentally, in the side view of FIG. 2, the height of the matted pillow 1 from the bottom surface 16 is, for example, about 9 cm at the uppermost portion of the overhead ridge portion 4 and about 10 cm at the uppermost portion of the cervical side ridge portion 5. The lowermost part of the concave groove portion 6 for the head is about 8 cm. As shown in FIG. 1, a required number of height adjusting sheets (mats) 20 may be laid on the bottom surface 16 side directly below the head support portion 10a according to the physique of the user H. ..

Further, as shown in FIGS. 1 and 2, the body support portion 10b is from the position opposite to the head concave groove portion 6 of the cervical side convex portion 5 to the chest H3 of the user H in a vertical cross-sectional view. It has an inclined surface 11 gently inclined so as to approach the bottom surface 16 side, and a horizontal plane 12 extending from the chest H3 of the user H to the vicinity of the waist H4. Incidentally, the inclination of the inclined surface 11 is attached, for example, in the range where the height from the bottom surface 16 is a little less than about 10 cm to a little more than about 3 cm. The height of the horizontal surface 12 from the bottom surface 16 is about 3 cm.

It should be noted that the horizontal plane 12 is not a perfect horizontal plane, but is inclined extremely gently at ± 1 degree or less with respect to a form including unevenness that changes by several mm in the vertical direction along the horizontal plane direction or a virtual horizontal plane. It also includes a form that is a nearly horizontal plane.

Further, the head support portion 10a and the body support portion 10b all have a rectangular shape in a plan view. In addition, on the upper surface side of the head support portion 10a and the central portion in the width direction of the body support portion 10b, a urethane layer 15 harder than soft urethane constituting other portions (mat portion 2 described below) is flat. It is arranged in a T-shape visually. Incidentally, in the pillow 1 with a mat, for example, the length in the height direction of the user H is a little over 77 to 80 cm, and the length in the width direction is about 60 to 100 cm.

The mat portion 2 is shown in an exploded perspective view of FIG. 3, and as will be described later, a recess (T-shaped shape) into which a pillow portion 3 formed of a hard urethane layer 15 having a T-shaped shape in a plan view is fitted. Thin-walled portion) 8 is provided.

The mat portion 2 is made of, for example, relatively flexible and lightweight (low density) soft urethane, and has a horizontal plane 8a on which the head side of the pillow portion 3 is placed, a pair of vertical wall surfaces 8b in the width direction, and a body support portion. It is formed of an elongated and gently curved inclined groove 9 which is opened upward in the central portion in the width direction of 10b, and has a T-shaped recess 8 as a whole in a plan view. It can be said that the inclined groove 9 corresponds to, for example, the form of the inner portion of the slide.

On the other hand, the pillow portion 3 (consisting of the hard urethane layer 15) is made of, for example, low-resilience urethane, and as shown in FIG. 3, the upper surface side of the head support portion 10a and the neck side convex portion of the head support portion 10a. An inclined portion 11b inclined diagonally downward from the central portion in the width direction of FIG. 3 toward the right in FIG. 3, and a horizontal portion 12b elongated and thinly extended from the inclined portion 11b to the vicinity of the user's waist. Is integrally possessed. The thickness of the inclined portion 11b and the horizontal portion 12b is thinner in the horizontal upper portion 12b in the example of FIG. 3, but may be substantially constant.

A pair of inclined portions 11a and horizontal portions 12a in the mat portion 2 are located on both sides of the inclined portion 11b and the horizontal portion 12b in the width direction. As shown in FIG. 4, the surfaces of the inclined portion 11a and the horizontal portion 12a are made of a non-slip material having an uneven shape, and are located on the inclined portion 11a and the horizontal portion 12a on both shoulders and the back of the user H. It may also prevent slipping and slippage. FIG. 5 is another example of the non-slip means. Further, the waist side end portion of the user H in the body support portion 10b is composed of a pair of end sides 13 on the mat portion 2 side and an end side 14 on the pillow portion 3 (hard urethane layer 15) side. The end sides 13 and 14 of the above are gently curved surfaces.

The inclined surface 11 of the body support portion 10b shown in FIG. 2 is formed by the inclined portions 11a and 11b, and the horizontal plane 12 of the body support portion 10b is formed by the horizontal portions 12a and 12b. Therefore, as shown by the downward arrow in FIG. 3, the head side of the hard urethane layer 15 (pillow portion 3) is placed on the horizontal plane 8a of the recess 8 of the mat portion 2, and the inclined groove 9 of the mat portion 2 is placed. By fitting the inclined portion 11b and the horizontal portion 12b of the hard urethane layer 15 (pillow portion 3) inside, the pillow 1 with a mat can be assembled accurately and easily. The pillow 1 with a mat is made of a cotton cloth or the like covering the entire outer surface thereof in the state of FIGS. 1 and 2, and is covered with, for example, a cloth sheet with a fastener (not shown).

Hereinafter, the usage state of the pillow 1 with a mat will be described together with the usage state of the pillow 30 of the comparative example. As shown in FIG. 6A, when the user H lies upward on the upper side of the matted pillow 1, the back of the head of the user H is the upper head convex portion 4 of the head support portion 10a and the concave groove portion for the head. 6 and the cervical side convex portion 5, the upper body including the shoulder portion of the user H is supported by the inclined surface 11 and the horizontal plane 12 of the body support portion 10b. As a result, the spine B1 of the user H easily supports almost the entire spine (cervical spine, thoracic spine, and at least the upper part of the lumbar spine) in a loose, smooth and natural curve, and joins the cervical spine of the user H during sleep. The burden can be reduced.

Further, as shown in FIG. 6A, the cervical side convex portion 5 and the inclined surface 11 gently incline the esophagus S1 when the sleeping user H is lying down from the throat toward the stomach 25. Since the posture is lowered, gastric acid is less likely to flow back to the throat side, so that the occurrence of aspiration pneumonia can be suppressed, for example. Further, since the spine B1 of the user H is less likely to give an unnecessary feeling of oppression to the trachea and organs of the upper body of the user H who is sleeping, there is a practical benefit of obtaining a safe and comfortable sleep.

Further, since the hard urethane layer 15 is arranged in a T shape on the upper surface side of the head support portion 10a and the central portion in the width direction of the body support portion 10b, the central portion of the back of the user H is supported by the hard urethane layer 15. The edge of the shoulder and the weight of the arm open the chest, straighten the back of the cat, and put it in a relaxed posture. When the user H turns over from his back to his side, the lower shoulders and arms slowly sink to disperse the weight, and the arms are less likely to become numb, so that it becomes easier to turn over naturally. In addition, since the ends 13 and 14 of the body support portion 10b have a gently curved surface, the entire upper body excluding the buttocks is moved to the upper side of the lower body including the buttocks when the user H is lying on his back. Since you can let it go to bed, it has the characteristic that it is easy to maintain the correct posture with your back straight.

On the other hand, as shown in FIG. 6B, when the user H lies upward on the upper side of the pillow 30 of the comparative examples in Patent Documents 1 and 2, the back of the head and the cervical spine of the user H are the heads of the pillow 30. It is supported by the support portion and the cervical spine support portion, and only the vicinity of the shoulder portion of the user H is located immediately below the shoulder portion and is supported by the inclined surface of the thoracic spine support portion that supports the upper cervical spine portion. As a result, since the spine B2 of the user H is bent in the middle of the thoracic spine, it is difficult to reduce the burden on the cervical spine of the user H during sleep.

Further, as shown in FIG. 6 (B), the pillow 30 of the comparative example causes the esophagus S2 in the supine position of the user H to be in a horizontal or upward posture while curving from the throat toward the stomach 25, so that gastric acid. Is likely to flow back to the throat side, which may induce aspiration pneumonia, for example. Further, since the pillow 30 of the comparative example does not support the trachea and organs of the upper body of the sleeping user H but is directly supported by the surface of the mattress, the spine B2 of the user H feels unnecessary oppressive feeling. Since it is easy to give, it becomes difficult to get a safe and comfortable sleep. As described above, it is understood that the pillow 1 with a mat has an advantage over the pillow 30 of the comparative example.

The pillow 1 with a mat is not limited to the above-described embodiment. For example, the hard urethane layer 15 may be made of highly breathable polyurethane or high-density, high-resilience polyurethane. When the hard urethane layer 15 is made of highly breathable urethane, it is less likely to get stuffy, and is suitable for care recipients and sick people who use it for a long time.

Further, the inclined groove 9 of the mat portion 2 has a shape of a vertical cross section that gradually narrows from the opening side to the bottom surface side, and the inclined portion 11b and the horizontal portion 12b of the pillow portion 3 (hard urethane layer 15) are formed. The vertical cross section of the above may also be in a form similar to the above-mentioned shape. In addition, the pillow portion 3 (hard urethane layer 15) may be integrally joined via an adhesive when it is fitted into the recess 8 of the mat portion 2.

Also, if the head support portion 10a is on the center side and the body support portion 10b is wrapped around it in a circumferential shape, it will be easier to store it compactly as a whole, so outdoor activities such as camping and mountain climbing, or measures against epidemic diseases It can also be easily used as a temporary bed for temporary illness.

In the present invention, by providing a gap 40 formed between the fitting B (combination wire portion) between the pillow portion 3 and the mat portion 2, the effect of releasing hot air and the convenience of entrainment, folding, etc. are provided. Can be expected. Further, although not shown, the effect of preventing the pillow portion 3 from coming off from the mat portion 2 can be considered by providing a step in the gap 40.

According to the present invention, almost the entire spine of the user at bedtime is supported in a loose, smooth and natural curved shape, the burden on the cervical spine can be sufficiently reduced, and it is unnecessary for the trachea and organs of the upper body. It is possible to provide a pillow with a mat that does not give a feeling of oppression and allows a smooth turn over naturally.
