Abstract

PROBLEM TO BE SOLVED: To provide a new core material for correcting and guiding a trunk with a simple structure, preventing improper deformation even while obtaining favorable action of a projection ridge part contributing to correction and guidance of a skeleton or a trunk, and capable of being provided to a market at proper manufacturing cost, and to provide a mattress using the same.SOLUTION: This core material 1 for correcting and guiding a trunk is formed with a large number of pressure reception projection ridges 11 on at least one face of an upper face and a lower face thereof in parallel, to a core material body 10 using an overall flat hard foamed resin as a material, and end part sides of the pressure reception projection ridges in the longitudinal direction are integrally connected by connection ribs 12.

Description

  The present invention relates to a core material for guiding trunk correction that can correct the posture of the body or guide it to a normal state, and a mattress using the core material.

For example, in the case where the skeleton such as the trunk of the body is not sufficiently aligned, many proposals have been made regarding bedding, particularly mattresses, in order to correct this or to induce it normally. Among these proposals, there is one proposed to arrange a large number of ridges extending in a direction perpendicular to the body height direction. These ridges give a stimulus that induces a movable state to the joint part of the skeleton of the trunk, and attempt to correct or guide the part (Patent Document 1, Patent Document 2).
As described above, although there has been a conventional idea for obtaining the trunk trunk correction effect by a large number of, for example, rod-shaped protrusions, it is not actually provided on the market as an actual product. The reason for this is that it is not sufficient to simply form such a ridge, but it is required to maintain its own solid shape and to be free of unnecessary deformation and displacement. It is thought that this is due to the failure to provide the appropriate one.
For example, in the case of Patent Document 2, a measure is provided to provide a mesh member made of a shape-retaining hard resin at the middle in the vertical direction of a columnar protruding ridge member to hold the protruding ridge portion. However, even in this case, it is inevitable that the structure and the manufacturing process are complicated, and in addition, the method of connecting and fixing the ridges at the upper and lower intermediate parts is sufficient for each ridge. Cannot be fixed.

  The mode for carrying out the present invention includes an embodiment described below, and includes various improved embodiments based on this technical idea.

Hereinafter, the present invention will be specifically described based on illustrated embodiments.
Reference numeral M denotes a mattress according to the present invention, which is formed by dividing a mattress element into three blocks as shown in FIGS. 1, 5, and 6, as an example. In the following description, unless otherwise required, each member is not described separately for each special mattress element.

First, the mattress M includes the core material 1 for guiding trunk trunk correction according to the present invention at the center. The core material 1 for guiding trunk trunk correction is substantially constituted by a single core material body 10 and further includes a buffer layer material 2 stretched on both upper and lower surfaces of the core material body 10.
In addition, about the mattress M and the core 1 for trunk | body correction | amendment induction | guidance | derivation, since this is used by the user H lying down, the direction of each board-shaped surface is made up and down.

First, the core body 10 of the core member 1 for guiding trunk trunk correction is integrally formed of, for example, a foamed resin, and an example thereof is foamed polypropylene.
The foaming ratio is about 30 times as an example. Therefore, the core body 10 has a hardness that hardly compresses and deforms in a range where the weight expected by a normal user H is applied. . This is defined as “hard foamed resin” in the claims of the present application. Needless to say, although there is little compression deformation in the practical use range, when weight is physically applied in the vertical direction, it is natural that each of them undergoes compression deformation when viewed microscopically.
The core body 10 is a flat plate-like member as an overall shape. When the mattress M is formed as the mattress element m as described above, the core body 10 is divided into, for example, three in the height direction of the user H. It goes without saying that it takes a dimensional form.

As an example, the core body 10 is provided with pressure receiving ridges 11 on both upper and lower surfaces. In addition, when it is necessary to distinguish and explain the pressure receiving ridge 11, the upper surface side is shown as the pressure receiving ridge 11 </ b> A and the lower surface side is shown as the pressure receiving ridge 11 </ b> B.
The pressure receiving ridge 11 has a substantially semicircular cross section when viewed in cross section as shown in FIGS. 1, 2, and 4. It has a continuous cylindrical shape. In more detail, as shown in FIGS. 1 and 3, a part of the top portion 11T is formed in a planar shape. Of course, the top portion 11T may not have such a shape, and a so-called round (R) cross section may be continuous. Further, even when referred to as a so-called R (R) cross section, it is not strictly limited to an arc cross section, and includes an elliptical arc shape and the like.

Furthermore, the end side of the pressure receiving ridge 11 is integrally connected by a connecting rib 12. In practice, the pressure receiving ridge 11 and the connecting rib 12 are integrally formed by foam molding using a predetermined mold cavity. Of course, in order to obtain such a shape, it is not necessarily limited to molding, and a processing form in which a part of a flat plate-like material is removed so that the pressure receiving ridge 11 remains by a hot wire cutter may be adopted. .
The height of the upper and lower end faces of the connecting rib 12 is preferably substantially coincident with the upper surface (top portion 11T) of the pressure receiving ridge 11, but the connecting rib 12 is somewhat lower than the upper end height of the pressure receiving ridge 11. However, even if it is high, it does not matter.

As the pressure receiving ridge 11 is formed, the boundary groove 13 is substantially provided. In addition, when it is necessary to distinguish and explain this boundary groove part 13, let the upper surface side be the boundary groove part 13A, and let the lower surface side be the boundary groove part 13B.
In this embodiment, the boundary groove portion 13A on the pressure receiving ridge 11A side forms a shallow groove portion 14 having a shape in which a part of the groove is filled. As a result, the pressure receiving ridges 11 located on both sides of the shallow groove portion 14 are strengthened in the mutual connection state, and the pressure receiving ridge 11A adjacent through the boundary groove portion 13B where the shallow groove portion 14 does not exist is bent or The support state of the user H is varied.

The core material main body 10 can be further provided with a buffer layer material 2 to constitute the core material 1 for trunk trunk correction guidance. The buffer layer material 2 is a cotton-like or web-like member in which appropriate materials such as synthetic fiber cotton and natural cotton are combined, and the buffer layer material 2 is preferably fixed to the core body 10 at the bonding portion 20. It is preferable to combine with the state.
The bonding portion 20 is bonded in a square frame shape between the portion of the connecting rib 12 and the pressure receiving ridges 11 located at both ends of the body in the front-rear direction. You may provide in the top part of the ridge 11.

Next, the mattress M using the core material 1 for guiding trunk trunk correction will be described. In this structure, an additional functional layer material 3 is provided on the upper surface of the buffer layer material 2 with the core 1 for guiding the trunk correction inside, and the whole is covered with a cover sheet 5.
First, the additional functional layer material 3 is formed by appropriately laminating a bulky layer 31 to which a soft synthetic resin foam material or a cotton-like web layer is applied, and a functional sheet 32 containing a functional material, and these are laminated on both the upper and lower sides. The quilting sheet 33 which becomes a surface shell material takes the form of wrapping.
As this additional function, the objective function given to the functional sheet 32 to which a functional paper or a fiber layer is applied is exhibited. Specifically, a lava fiber mixed nonwoven sheet, a germanium mixed nonwoven sheet, tourmaline Any one of these mixed nonwoven fabric sheets or a combination thereof is used, and a heat retaining function, a deodorizing function, an antibacterial function, an antifungal function and the like are imparted. Of course, not only such a special function but also a buffer function centered on the bulky layer 31 is included as an additional function. In addition, when a material composed of a suitable zirconium silicate-based ceramic mixed with fibers as a material for the bulky layer 31 is used, a moisturizing effect can also be obtained by the far-infrared effect.

Such an additional functional layer material 3 is included, and this is covered with a cover sheet 5 to form a mattress M.
The cover sheet 5 is configured in a bag shape and is housed so as to wrap them in a state in which the core 1 for trunk trunk correction and the additional fiber layer material 3 are laminated in the housing 51. In closing, it is preferable to close with the fastener 52. Further, when the mattress elements m are divided, the connecting portion 53 is configured to be foldable. Moreover, it is preferable to provide the surface fastener 54 which mutually engages in the side end surface of the cover sheet 5 in the connection part 53, and to ensure the maintenance of the flat board state at the time of use.
Furthermore, the cover sheet 5 is preferably provided with a loop-like member or a string-like member as the handle 55 at an appropriate position in consideration of handling it in three.

The present invention has a configuration as described above. When the user H lies down using the mattress M, the following corrective action is performed.
That is, the pressure receiving ridges 11 are formed in a number extending in the direction perpendicular to the height direction of the user H, and the action of both the pressure receiving ridges 11 and the boundary groove 13 between them is substantially as shown in FIG. As shown in the figure, the bone parts B constituting the joints such as the lumbar vertebrae and the spine in the trunk are guided in the pulling direction, and as a result, the skeleton is corrected and guided. At the same time, it has the effect of stretching the muscles, ligaments, blood vessels, etc. around each joint. Incidentally, in order to effectively guide the correction of each joint, it is important that the peripheral muscles are elongated in the previous stage. However, the mutual shape of the pressure receiving ridge 11 of the present invention and the boundary groove 13 is the same. Therefore, the above functions are effectively and reasonably performed.
Further, when the surface on which the shallow groove portion 14 is formed between the pressure receiving ridges 11 is used, the user H can obtain a so-called soft feeling of use.

  According to clinical use results in the process of completing the present invention, for example, in the case of a child who has difficulty in self-supporting walking having an abnormality in the trunk, the use of the mattress M corrects the state of the trunk. Independent walking is possible.

[Other Embodiments]
The present invention is based on the embodiment described above as one basic technical idea, but the following modifications can be considered.

First, what is shown in FIG. 8-1 (a) is one in which the pressure receiving ridge 11 is formed exclusively on one side.
Of course, in order to obtain wider performance specifications and dimensional specifications, the pressure receiving ridges 11 are preferably formed on the upper and lower surfaces of the core body 10 as in the embodiment described above, but the user is limited. In such a case, it may be formed only on one side.

  Further, the pressure receiving ridge 11 described above has a substantially semicircular ridge shape, but a ridge having a sine curve cross section (FIG. 8-1 (b)), a ridge having a trapezoidal cross section, etc. (FIG. 8-1 (c)) may be used.

  Furthermore, not only the shallow groove portion 14 that fills the boundary groove portion 13 as shown in FIG. 2, but also the formation pitch of the trapezoidal pressure receiving ridge 11 as shown in FIG. Can take.

  In addition, the shallow groove portion 14 is formed in the same shape at every constant pitch, and different ridge groups can be formed by changing the arrangement position of the shallow groove portion 14 as shown in FIG. 8-2 (e). There is no problem.

  In the embodiment described above as shown in FIG. 2, the boundary groove 13 between the pressure receiving ridges 11 is present at the same position in the vertical direction, and the formation pitch thereof is matched. It is also possible to make the formation pitch different as shown in FIG. In the fourth item of the claims of the present application, the meaning that the formation pitch is matched indicates that the formation position is also matched in addition to the matching of the pitch dimension. Of course, as shown in FIG. 8-2 (g), although the formation pitch dimension is the same, the positions of the formation portions can be varied. Further, the upper and lower pressure receiving ridges 11 may have different shapes.

  Further, in FIG. 8-2 (h), a hole 112 is formed in the site of the pressure receiving ridge 11 so that the deformation state can be set. It should be noted that the punch holes 112 may be formed not only at all the pressure receiving ridges 11 but also only at necessary portions.

In this way, the present invention is mainly positioned as a guide for correction of the trunk and the like, and in addition to the user H having such a trunk disorder and a skeletal displacement disorder, even a normal person can have a daily life. It can correct the deformation of the trunk that comes from customs.
In addition, for a user H who is a healthy person or a person with a disability, as a result, incidental effects such as a sleep effect can be obtained.
