Description

    The present invention relates to a so-called waist pillow applied to a human waist.

The lumbar part of the human body is a part that places a heavy physical or weight burden on a person who walks on two legs, and there is a high possibility that a failure occurs in the lumbar part.
For this reason, scolding the lower back is an important factor for maintaining healthy human function and maintaining health. Crawling the waist requires consideration not only when a person walks but also when a person sleeps. Actually, consideration has been given to human history since ancient times, and the burden on the waist as a major concern in recent years. When a person goes to sleep, it is necessary to alleviate this in some way and to recover from the injury caused by the burden.

  Also, because the human race walks on two legs, it takes a burden on the waist, but the burden on the waist is not necessarily burdened only when the person is standing on two legs, even when sleeping in a lying state On the contrary, the burden on the lumbar region can be recovered due to the posture of the recumbent, etc. On the contrary, the burden increases or another burden is applied.

有機的な構造の体の持ち主であることに起因する。
このため、少なくとも横臥状態での休眠時にはできるだけ腰部への負担を減らし、負担が掛かったことによる傷害などの回復を図るための有形無形の努力がなされて来、多くの用具、器具が開発されてきた。

This is due to the fact that the body has an organic structure.
For this reason, tangible and intangible efforts have been made to reduce the burden on the lower back as much as possible at the time of dormancy while lying down, and to recover from injury caused by the burden, and many tools and instruments have been developed. It was.

  Patent Document 1 discloses an air pillow for a waist that can support the waist part in a well-balanced manner and has a simplified overall structure.

  Patent Document 2 is a waist pillow formed from a polyurethane foam material and a high density low resilience polyurethane foam, and a breathable three-dimensional knitted fabric superimposed on the upper surface thereof to form a ventilation gap between the body and the waist pillow. The waist pillow which can aim at dispersion | distribution of the body weight with respect to is disclosed.

However, in spite of various technical improvements provided by these various development efforts, there has not yet been provided an almighty and satisfactory one.
It does not mean that development and provision efforts are lacking and there is a problem with the development attitude, but that the target is the most uncertain human living thing that is difficult to grasp and understand. It can be said. Therefore, it is appropriate that the problem to be solved by the idea of the present application is to develop a completely new technology rather than to improve the problems of the technology developed in the past.

According to the present invention, the planar shape of the flat horizontally long bottom surface is a symmetrical mountain shape with the upper side sharpened at the center, and the lower side is cut into an acute angle with a convex-concave unevenness at intervals of approximately four equal parts in the horizontal direction. It is formed in a saw-tooth shape, raised in a mountain shape above the bottom surface, its ridgeline bends at a position corresponding to the indentation in the lower side, and the left and right ridgelines are obtusely downward with respect to the central ridgeline, respectively. A pillow for a person's waist that has a lowered trapezoidal shape and is entirely made of low-elasticity foam.
A person's waist pillow is provided.

The lateral length is preferably 1.5 to 2.5 times the width of the central portion in the vertical direction, and the thickness of the central portion is preferably 35% to 45% of the length of the central portion in the vertical direction. .
The width of the central part in the vertical direction is preferably 25 cm to 40 cm.
The scale of a person's waist pillow can be changed within a certain range depending on the person's physique, but the scale of the above is preferred because an effective action cannot be obtained if it is too large or too small .

  The left and right sides of the human waist pillow may be approximately perpendicular to the left and right longitudinal axes and substantially parallel to the left and right, but the shape of the left and right ends does not contribute to the function of the pillow. There is no need to specify.

  According to the waist pillow of the present invention, the spine is in the most natural shape, that is, the standing posture in many sleeping positions, that is, even when the sleeping position changes due to turning over, etc. Can be kept in the same shape as or as close to it as possible, so that you can get enough sleep and at the same time relieve physical stress when you are awake.

FIG. 1 is a plan view of the present invention, FIG. 1 is a plan view, FIG. 2 is a right side view, FIG. 3 is a bottom view, FIG. 4 is a sectional view taken along line IV-IV in FIG. It is a VV line section surface.
This entire waist pillow is a molded product of low-resilience polyurethane foam. Therefore, although it is an integrated structure of homogeneous materials, the entire portion can be configured in the same shape as a composite, for example, the bottom portion and other portions are formed of different materials or members. However, it is necessary that it is a low-resilience polyurethane foam at least except the bottom.

  The low-rebound resilience foam in the present invention may be anything that is standardly referred to as a low-rebound resilience foam. More preferably, medium physical properties, a density of about 60, a hardness of about 30, and a rebound resilience of about 3 are suitable. is there.

In the figure, reference numeral 1 denotes a waist portion pillow body.
In the waist cushion of this embodiment, the ridgeline 2 on the upper surface of the waist cushion is not on a straight line as a whole, but the left and right sides 2 'are bent outwardly at an obtuse angle at a position corresponding to the lower edge 3 of the recess. It is trapezoidal. This is in conformity with the lateral planar shape of the waist-holding pillow, and is adapted to follow the body shape of the person's waist when the person turns over.

The sawtooth-shaped recess 3 on the lower side is located at approximately four equal positions on the left and right. The position error is preferably about 10% in both the left and right directions, and if the error is larger than that, it is not preferable because the shape of the spine that is close to the natural posture can not be obtained appropriately. .
The front end 5 of the projecting portion 4 in the lower central portion is slightly inward from the lower end positions 6 on the left and right sides, but the positions of these lower end positions 5 and 6 may be substantially on the same line on the left and right. However, it is preferable that the position of the tip 5 of the projecting portion 4 at the center portion does not protrude outward from the position of the left and right protrusions 6. This is because such a shape makes it difficult to maintain the natural state of the spine when going to bed.

The bottom surface 7 is substantially planar. Although there may be some unevenness or fine unevenness, the bottom surface prevents the action because it is a stable positioning of the lower back pillow and properly receives the human body at bedtime by the upper contour shape Or the shape which does not fully exhibit is not preferable.
The two flat portions divided by the ridge lines 2 and 2 ′ are preferably substantially flat as is the bottom surface. This is because if there are irregularities more than necessary, the human body will be adversely affected.

  The size of the waist-holding pillow is about 64 cm in the lateral direction, about 27 cm in the front-rear direction on both sides, about 66 cm in the front-rear direction on the left and right central portions, and about 8 cm in thickness at the ridgeline position. The scale of the waist cushion of the present invention is not necessarily the same as the scale of this embodiment, but the error is preferably about ± 10%. In particular, even if the heat of the ridge portion is too thick or too thin, it is not preferable because the effect of maintaining the spine in a state close to naturalness cannot be obtained sufficiently.

  It is a top view of the pillow for human waists of this invention.   It is a right view of a person's waist part pillow of the present invention.   It is a bottom view of the person's waist pillow for the present invention.   It is the IV-IV sectional view taken on the line of FIG.   It is the VV sectional view taken on the line of FIG.
