Description

  [Technical Field] The present invention relates to a mat for correcting a posture during sleep by using it on a futon or a bed.

The general posture of standing upright in Japan is that the head is slightly forward and the back is rounded, the pelvis is tilted backwards, the knee is externally rotated, the toes are internally rotated, and the internal thighs tend to be . This is not only a morphological anthropological feature, but also a historical feature derived from the traditional lifestyle of wearing sandals and clogs.

When a Japanese who has established such a posture lies on a flat bedding during sleep, the weight is concentrated on the occipital region, the spine standing muscle, the gluteus muscle, and the ribs at the center of the back, as shown in FIG. In addition, at the time of supine, both arms are weakened and the elbow joint falls downward, so that the shoulder joint is raised and the upper part of the trapezius muscle is stretched and pulled to stretch the latissimus dorsi muscle. As a result, the pelvis further inclines and the knee joint bends. In other words, the posture continues to be the same as when standing, even when lying on the back, and the muscle tension throughout the body is not easily relaxed. Rolling over during sleep is an action for unconsciously stretching muscles to relieve the tension. In fact, people who feel that they are in a supine position often sleep in a lying or prone position, resulting in sleep problems such as poor sleep, not getting tired enough to sleep, and having trouble getting up. Or snoring and sleep apnea syndrome.

The relationship between the quality of sleep and the posture during sleep has been attracting attention from early on, and a wide variety of mats that exert a body pressure dispersion effect due to a low repulsion material and a surface uneven structure have been developed and spread. In addition, a mat for mounting a structure that exerts a posture correction effect, such as a back muscle stabilization mat according to Patent Literature 1 or a combination of a posture correction stand and a mat according to Patent Literature 2, has been proposed.

However, the floor mats, which have a body pressure dispersion effect due to the low-elasticity material and the uneven structure of the surface, cause the user's body to sink into the bedding and closely adhere to it, so that some people feel a sense of pressure and discomfort, and the spine is rounded The effect of positive correction cannot be expected. Further, the back muscle stabilization mat according to Patent Document 1 restricts turning over to the lying position by a hard core material in the mat, and forcibly fixes the back muscle, that is, the spinal column. Is strong and lacks comfort. Further, the combination of the posture correction table and the mat according to Patent Document 2 is intended to improve low back pain by forcibly extending the lumbar spine by placing a step between the lower body and the upper body on a higher posture correction table. However, users not only feel the pressure on the lumbar vertebrae at all times but lack comfort, but there is also a possibility that the upper body may fall from the correction table due to some body movement during sleep, so it is not always practical It cannot be said that it is expensive

The present invention solves the problems of the prior art, and provides a mat that can correct the posture of the body in the supine position without causing the user to feel restrained or uncomfortable with an extremely simple and low-cost structure. Let it be an issue.

In order to solve the above-mentioned problems, the mat according to claim 1 of the present invention is a substantially rectangular mat, and is characterized in that a concave portion is provided at the center of the head side. The floor mat is, for example, a soft material such as urethane sponge having a certain repulsive force coated with a fabric having good air permeability, and can be manufactured very simply and at low cost. As the soft material, if a synthetic resin fiber such as plastic (polypropylene) molded into a three-dimensional network like the inner fiber structure of loofah is used, durability and breathability can be improved, which is more preferable. It is.

Further, the floor mat according to claim 2 is the floor mat according to claim 1, wherein the head side is located at the center of the thoracic vertebra when the head is lying in use, and the foot side is Is located at the user's ankle, and the bottom of the recess is located approximately at the center of the user's lumbar spine. The floor mat needs to be provided in a plurality of sizes according to the user's body, but in any size, the center part of the user's lumbar vertebra, that is, the lower body generally below the second to fourth lumbar vertebrae is the floor mat. It is located on the top, and the ridge is sized so that it protrudes first from the mat and contacts the ground.

Further, the floor mat according to claim 3 is the floor mat according to claim 2, wherein the left and right convex portions sandwiching the concave portion are inclined surfaces having an upward gradient from the head side side toward the foot side, respectively. It is characterized by having. With this configuration, when the user lies on the mat, the elbows of both arms are positioned on the inclined surface and the wrist portion is naturally held at a position higher than the shoulder.

The floor mat according to the present invention tends to lean backward to a state close to the original S-curve when the vertebral column tends to be stooped only by laying on a conventional bedding such as a futon or bed and supine on it. Since the pelvis is naturally corrected to anteversion, not only the symptoms of sleep disorders are alleviated by relieving the tension of the muscles of the whole body and making breathing easier, but also activation of the body's metabolism, blood circulation promotion, stiff shoulders It can be expected to have effects such as improvement of low back pain, improvement of snoring and sleep apnea syndrome. Moreover, even if a special structure is not provided, the user's body does not fall from the floor mat, and the user can use without feeling a sense of pressure or discomfort.

(First embodiment)
Hereinafter, the structure and operation effect of the mat according to the present invention will be described with reference to the drawings. FIG. 2 is a plan view of the mat 10 according to the first embodiment of the present invention, FIG. 3 is a view showing the floor mat 10 viewed from the head side, and FIG. 4 is a view showing the foot side. 5 is a diagram showing a state viewed from the left side. FIG. 6 is a plan view showing a state in which the user lies on the mat 10, and FIG. 7 is a side view showing the state viewed from the left side.

  The mat 10 is provided with a concave portion 12 at the center of the head side, and the convex portions 11 protrude right and left so as to sandwich the concave portion 12. The overall size of the mat 10 is arbitrary depending on the size of the user's body, but as shown in the use state diagram, the head side is generally positioned below the central portion of the thoracic vertebra. In this case, it is assumed that the upper side of the recess 12 is positioned below the central portion of the user's lumbar vertebra and the side of the foot is positioned below the user's ankle. Further, both shoulders of the user are grounded above the side of the head of the mat 10, and both arms of the user are generally placed on the projections 11 from the elbows. The thickness of the mat 10 is also arbitrary depending on the size of the user's body, but about 60 mm is preferable for adults.

  As shown in the side view of the usage state, when lying on the mat 10, the lower body from the center of the lumbar vertebra and above the ankle is held at a position higher than the upper body by the thickness of the mat, and curls when standing up. The vertebral column was corrected to a state close to the original S-curve. On the other hand, since the elbows of both arms are held high by the thickness of the mat, the weight of the arms does not interfere with the body, the shoulder joints lower, the rib cage expands, the chin rises, and the airway is sufficient Released. In addition, the shoulder joint naturally lowers so that the trapezius and latissimus dorsi muscles are not loaded. In addition, the heel falls by the thickness of the mat and the load is no longer applied, so there is no overextension of the knee and the lower leg stretches naturally. These synergistic effects correct the pelvic posterior inclination. As a result, muscle tension throughout the body is relieved, breathing is facilitated, and symptoms such as sleep disorders are relieved.

FIG. 8 is a plan view of a mat 20 according to the second embodiment of the present invention, FIG. 9 is a diagram showing the state seen from the head side, and FIG. 10 is a diagram showing the state seen from the foot side. 11 is a diagram showing a state viewed from the left side. FIG. 12 is a side view of the user lying on the mat 20 from the left side.

The planar shape of the mat 20 is the same as that of the mat 10, but the left and right convex portions 21 sandwiching the concave portion 22 each have an inclined surface with an upward slope from the head side to the foot side. A peak portion 24 is provided so as to fall from the position where it hits the palm to the mat body portion 23. When the user lies on the floor mat 20, the ends from both elbows extend upward along the inclined surface, and both palms grip the peak portion 24.

  In the mat 20 according to the second embodiment, since the convex portions 21 are provided with inclined surfaces, the user's arms are naturally held slightly upward, so that both shoulders can be comfortably attached to the bedding surface. Touch the ground and lower the shoulder joint. For this reason, the effect which expands a rib cage more than the mat | matte mat 10 which concerns on 1st Embodiment, and makes it easy to breathe can be anticipated.

The mat according to the present invention has a very simple structure and can be manufactured at a low cost. In addition, it can be used simply by laying on existing bedding such as a futon or bed, and the user does not feel a sense of restraint or discomfort. Therefore, it is easy to spread in home bedrooms, accommodation facilities, hospitals, care facilities, and the like.
