Description

  TECHNICAL FIELD The present invention relates to a mattress capable of suitably performing a stretching exercise for reducing stiffness and pain in the neck of the body.

Depending on the lifestyle and work environment, more and more people are complaining of pain and discomfort in the neck and shoulders, including so-called stiff shoulders.
As measures against such discomfort, simple measures such as application of a patch or an ointment are performed. Furthermore, massages, acupressure, and the like are also performed by applying techniques to muscles and tendons directly by qualified persons and the like.
On the other hand, when directly stretching a muscle or a tendon by itself, it is performed in a relaxed state in which an appropriate cushion material is used and a load is not applied to the muscle or the tendon (see, for example, Patent Document 1).
As a result of considering the conventional operation, the present inventor does not always show a sufficient effect in the exercise of moving the muscles near the affected part in a relaxed state, and rather holds the muscle in a constant tension state, We found that it is effective to perform stretching exercises in this state.

FIG. 6 is a bottom view and a side view showing the difference in the hold range when the hardness of the elastic core material is changed. It is a perspective view showing other examples.

  The best mode of the mattress for improving neck and shoulder pain of the present invention is as follows, but it is possible to make appropriate changes to this mode within the scope of the technical idea of the present invention.

The mattress 1 for improving neck / shoulder pain of the present invention is a device used for stretching exercise for improving neck / shoulder pain, etc., and as shown in FIG. It is used in a supine position on the top.
The cervical shoulder pain improving mattress 1 comprises an elastic core material 2 and a cover sheet 5 covering the elastic core material 2. In this embodiment, it has a rectangular parallelepiped shape as shown in FIG. did. Note that, as shown by a virtual line in FIG. 2, a rounded shape with corners removed may be used.

  Further, the elastic core material 2 has a three-layer structure and comprises support layers 21 and 23 arranged on two upper and lower surfaces, and an intermediate layer 22 arranged between the support layers 21, 23. Is a foam rubber, while the intermediate layer 22 is a foam resin softer than the support layers 21 and 23.

The support layers 21 and 23 are, for example, 100% natural latex foam having a density of 70 to 75 kg / m ³ and a thickness of 30 mm.
The hardness of such support layers 21 and 23 (25% JIS K 6400-2 D method) is 45 ± 13.5 (N), preferably 45 ± 9 (N), and more preferably 45 ± 4.5. (N).
By setting the hardness of the support layers 21 and 23 as described above, the hardness of the elastic core material 2 can be set to a suitable value described later.

On the other hand, the intermediate layer 22 is made of urethane foam as an example, and has a thickness of 60 mm as an example.
The hardness of such an intermediate layer 22 (25% JIS K 6400-2 D method) is set to 39.2 ± 14.7 (N).

In this embodiment, as an example, the intermediate layer 22 is configured by using Supersoft (ether) EFD manufactured by Aisin Sangyo Co., Ltd.
Density (kg / m ³ ): 17.5 ± 2
Hardness (N): 39.2 ± 14.7
Tensile strength (kPa): 39 or more Elongation (%): 100 or more Compressive residual strain (%): 7 or less

The hardness of the elastic core material 2 formed by stacking the support layer 21, the intermediate layer 22, and the support layer 23 is 52 ± 15.6 (N), preferably 52 ± 10.4 (N), and further, It is preferably 52 ± 5.2 (N).
The hardness of the elastic core material 2 will be described later in detail, but the hardness applied to the muscle of the user P near the scapula and the muscle near the neck and the hold state of the muscle can be made suitable. If it is too hard or too soft, the load concentrates on a part and a suitable hold state cannot be obtained.

The planar shape of the elastic core material 2 is, for example, a rectangular shape of 300 mm × 400 mm, and is covered with a cloth cover sheet 5.
Here, the cover sheet 5 is made of a material that exhibits non-slidability between the back of the head and the back of the user P. For example, the cover sheet 5 is woven from a mixed fiber of 94% polyester and 6% polyurethane. Bare woven cloth is used.
Further, the bare fabric cloth has a direction of expansion and contraction, and in this embodiment, it is set so that it can be expanded and contracted in the width direction of the cover sheet 5 and cannot be expanded and contracted in the longitudinal direction. This makes it possible to stabilize the posture of the user P when moving the affected part of the shoulder and neck, and to make the muscle hold state and the load applied to the muscle more suitable.

The neck / shoulder pain improving mattress 1 of the present invention is configured as described above as an example. Hereinafter, the usage mode of the neck / shoulder pain improving mattress 1 will be described.
First, the user P installs the cervical shoulder pain improving mattress 1 directly on the floor or on a yoga mat or the like laid on the floor, and becomes supine on the mattress 1. In this embodiment, as an example, as shown in FIG. 1, in a low-profile view (plan view), the upper part of the occipital region B extends from the mattress 1 for improving neck and shoulder pain, and the scapula S (SR, SL) from the neck C. The range up to is supported by the mattress 1 for improving neck and shoulder pain.
In this state, in the neck / shoulder pain improving mattress 1, the intermediate layer 22 is mainly crushed by the weight of the user P, and the support layers 21 and 23 are also crushed to some extent.

Next, the user P performs an action of pressing the occipital region B against the cervical shoulder pain improving mattress 1.
In this state, as shown in the side view of FIG. 3 (a), the neck / shoulder pain improving mattress 1 is further crushed, and at the same time, the muscles around the waist of the user P to the vicinity of the neck C are both the spine. A tension state is created in which the muscles near the scapula S (the trapezius muscle, the subspinal muscles, the great oval muscles) and the neck C (the headboard-like shape) are tightened around the erector spinal muscles along the longitudinal direction. The muscles and scapular muscles are in a tense and tense state, and a wide range as indicated by the diagonal lines in the bottom view of FIG. 3A is held by the reaction from the neck and shoulder pain improving mattress 1.

Then, the user P moves the cervical shoulder arm in this state, whereby the muscles near the scapula S (trapezius muscle, infraspinatus muscle, great oval muscle) and the muscles near the neck C (head plate muscle, levator scapulosus muscle). ) Is to be moved while being held on the mattress 1 for improving neck and shoulder pain.
When the muscle is moved in such a tense and held state as described above, it is possible to obtain the same state as moving the muscle under a load. Is strengthened, and an effect such as a lighter arm appears. Further, when the muscle is moved while being held, so-called fascia release is promoted, and pain and stiffness can be alleviated.
Further, by repeating the above-described series of operations, the erector spinae muscles are strengthened, and posture correction is promoted.

As described above, when the user P moves the cervical shoulder arm, the cover sheet 5 exhibits non-slidability between the occipital region B and the back of the user P. It is possible to prevent the user's muscles from being lost (they will not be lost), and hold the muscles of the user P appropriately. Such non-slippery performance is premised on that the user P is in the clothes state, but the non-slipperiness was not impaired even in the non-clothes state.
On the contact surface between the cover sheet 5 and the elastic core material 2, the non-slidability is exerted by the action of the support layers 21 and 23 made of natural latex foam.

As described above, in the neck / shoulder pain improving mattress 1 of the present invention, the elasticity of the elastic core material 2 is set to 52 ± 15.6 (N), whereby the muscles near the scapula S and the muscles near the neck C are set. It is possible to carry out the holding in a suitable manner, and the case where the hardness of the elastic core material 2 was harder than this and the case where it was softer were verified.
First, when the hardness of the elastic core material 2 is harder than 67.6 (N), as shown in the side view of FIG. 3 (b), the degree of crushing of the neck and shoulder pain improving mattress 1 becomes slight. As shown by the diagonal lines in the bottom view of FIG. 3 (b), cervical shoulder pain is observed in the vicinity of the erector spinae muscles along the longitudinal direction on both sides of the spine and a narrow range of a part of the trapezius muscle from the shoulder to the neck. The reaction from the improvement mattress 1 brought it into a state of being held intensively.

  Further, when the hardness of the elastic core material 2 is softer than 36.4 (N), the crushed condition of the neck and shoulder pain improving mattress 1 becomes remarkable as shown in the side view of FIG. 3 (c). As a result, the cervical shoulder pain improving mattress 1 is compacted to such an extent that the hardness of the floor can be transmitted, and as shown by the diagonal lines in the bottom view of FIG. The narrow area of the trapezius muscle around the erector spinae muscle and from the shoulder to the neck was intensively held by the reaction from the mattress 1 for improving neck and shoulder pain.

  As described above, in the cervical shoulder pain improving mattress 1 of the present invention, since the hardness of the elastic core material 2 is 52 ± 15.6 (N), the user P uses the occipital region B for cervical shoulder pain improving. The muscles near the neck C are tightened from around the waist of the user P while holding the whole muscles near the scapula S and the muscles near the neck C by performing an action of pressing the mattress 1. Is something that can be done.
