Summary of the Invention

Problems to be Solved by the Invention

[0004] Among the electromagnetic waves applied to the body, PEMF, for example, is said to be particularly effective. Devices using PEMF are expected to have effects on promoting cell repair and improving blood circulation, and have attracted attention in recent years. However, conventional PEMF generating devices employ a circular coil structure, and due to their large size and weight, they have hindered storage inside the mat and folding. On the other hand, with recent technological innovations, miniaturization and weight reduction have advanced, and various shapes other than circular have emerged on the market, making it easier to store inside the mat. On the other hand, in a mat having a relaxation device stored inside as described in Patent Document 1, there is a problem in that it is difficult to fold at the portion where the device is arranged and it is difficult to carry.

[0005] In view of the above-mentioned problems, the present invention aims to provide a mat device that is easy to carry even when an electromagnetic wave generator is built inside, and that also has excellent performance. [Means for solving the problem]

[0006] The present invention, which solves the above problems, comprises a mat body on which the body is placed and a plurality of electromagnetic wave generating devices that generate electromagnetic waves, wherein the mat body has a flexible void, the void is provided over the entire width direction of the mat body and includes a foldable void that makes the mat body foldable, and the electromagnetic wave generating devices are arranged inside the mat body at a position away from the foldable void. This configuration allows the mat device to be folded in the folding gap, making it highly portable, and by housing the electromagnetic wave generator inside, it is possible to provide a mat device with enhanced performance. [Effects of the Invention]

[0007] This invention solves the above problems by providing a mat device that is easy to carry even with an electromagnetic wave generator inside, and that also offers superior performance. [Brief explanation of the drawing]

[0008] [Figure 1] This is a plan view of the mat device in use according to an embodiment of the present invention. [Figure 2] This is a side view of a folding mat device according to an embodiment of the present invention. [Figure 3] This is a schematic cross-sectional view of a mat device according to an embodiment of the present invention. [Figure 4] This is a partially exploded perspective view of a mat device according to an embodiment of the present invention. [Figure 5] This is a partially exploded diagram illustrating a mat device according to an embodiment of the present invention. [Figure 6] This is an enlarged explanatory diagram of a mat device according to an embodiment of the present invention. [Figure 7]This is a schematic cross-sectional view of a mat device according to an embodiment of the present invention. [Modes for carrying out the invention]

[0009] The mat device X according to each embodiment of the present invention will be described below with reference to the drawings. The description will detail the configuration of the embodiment, the method of implementation, and the modified examples in that order. The embodiments described below are merely examples of the present invention and are not limited to these embodiments. Furthermore, the term "abbreviated" in the application documents refers to shapes that have been chamfered or rounded, and shapes in which the elements constituting the shape have been modified or altered in length to the extent that it does not impede the purpose or effect of the configuration. Furthermore, in this specification, the length direction refers to the direction in which the entire shape is longest when viewed as a rectangle or cuboid, and the width direction refers to the direction in which the width is the second longest. In addition, the thickness direction refers to the direction in which the entire shape is shortest when viewed as a cuboid.

[0010] As shown in Figure 1, the mat device X according to the present invention comprises a mat body 1 on which the body is placed and a pocket portion 2 located on the upper surface of the mat body 1. The mat body 1 has a heating portion 14 that heats the surface of the mat body 1, and the pocket portion 2 has a plurality of pocket bodies 21 that hold a plurality of stone materials S in place and a gap portion 22 formed between the pocket bodies 21. The gap portion 22 is provided over the entire width direction of the mat body 1 and includes a foldable gap portion 221 which is more flexible than the pocket bodies 21 and allows the mat body 1 to be folded. A group of a plurality of pocket bodies 21 (21A, 21B, 21C) is provided so as to sandwich the foldable gap portion 221. As a result, as shown in Figure 2, the mat body 1 can be folded in the foldable gap portion 221, and heating by a plurality of stone materials S is also possible through the group of pocket bodies 21, resulting in a mat device X with high performance.

[0011] Furthermore, as shown in the schematic cross-sectional view of Figure 3, the mat device X according to the present invention has a mat body 1 made up of multiple layers. Also, as shown in Figures 4 and 5, the mat device X comprises a mat body 1 on which the body is placed and multiple electromagnetic wave generators 3 that generate electromagnetic waves. The mat body 1 has a flexible void 22, which extends across the entire width of the mat body 1 and includes a foldable void 221 that makes the mat body 1 foldable. The electromagnetic wave generators 3 are arranged inside the mat body at a position away from the foldable void 221. As a result, the mat device X is highly portable because it can be folded at the foldable void, and its usability is enhanced by housing the electromagnetic wave generators 3 inside.

[0012] As shown in Figure 1, the mat device X comprises a mat body 1 on which the body is placed, a pocket section 2 positioned on the upper surface of the mat body 1, a heating section 14 for heating the mat body 1, an electromagnetic wave generator 3 for emitting electromagnetic waves toward the upper surface of the mat body 1, and a control section 4 for controlling the heating section 14 and the electromagnetic wave generator 3.

[0013] As shown in Figure 3, the mat body 1 is a sheet component made up of multiple layers, and includes a surface portion 11 on which the user lies, a heat storage portion 12 that contacts the surface portion 11 and stores heat from the heating portion 14, a front buffer portion 13 that absorbs unevenness, etc. of the heating portion 14, a heating portion 14 that heats at least the surface portion 11, a heat reflecting portion 15 that reflects the heat from the heating portion 14 back towards the surface portion 11, a back buffer portion 16 that absorbs unevenness, etc. caused by the electromagnetic wave generator 3, and a water-resistant back portion 17.

[0014] The surface portion 11 is a sheet material made of polyurethane, with an outer shape of approximately 120cm to 180cm in length and 30cm to 70cm in width so that a person can lie on it. The surface portion 11 has pocket portions 2 except for both ends in the length direction, and the surface is made uneven by the stored stone material S.

[0015] The heat storage part 12 is a sheet member having a predetermined heat insulation property and heat storage property, and is provided so as to contact the layer on the back side of the surface part 11. Since the heat of the heating part 14 is evenly distributed on the sheet by the heat storage part 12, even when the heating part 14 heats only a certain range, the surface part 11 can be evenly heated. As a result, the design width of the heating part 14 is widened, and the use performance can be enhanced even with a lightweight.

[0016] The front side buffer part 13 is a sheet member provided directly above the heating part 14 and is made of heat-resistant cotton. Its thickness is at least larger than the thickness of the heating part 14, so that the unevenness of the heating part 14 can be reduced. In addition, since it is provided directly below the heat storage part 12, heat can be dispersed and supplied to the heat storage part 12, so that uniform heating can be achieved more effectively.

[0017] The heating part 14 is a part that is heated by passing electricity, and a linear heating wire 141 is arranged on the sheet. On the other hand, the heating part 14 only needs to be able to heat the surface part 11, and it may be a film heater or an electromagnetic induction heating device combined with other metal parts.

[0018] As shown in FIGS. 4 and 5, the heating wire 141 is provided so as to meander on the surface of the layer constituting the heating part 14. When the meandering mode is described in detail, it is arranged in a zigzag manner such that a plurality of parallel parts 142 provided in a direction parallel to the length direction of the folding gap part 221 (the direction that becomes the axis of folding) are arranged in a row. In addition, the parallel part 142 is provided directly below the folding gap part 221. Thereby, the portion where the heating wire 141 is bent during folding is reduced, and the durability of the heating wire 141 can be improved.

[0019] By heating with the heating wire 141, the flexibility of the entire mat body 1 is improved, and folding can be freely performed at an arbitrary position. In addition, since the heating wire 141 is a wire material, the whole can be made thin, and the carrying performance can be enhanced. Although a nichrome wire or the like can be used for the heating wire 141, it is preferable to use carbon fiber in order to impart bending resistance.

[0020] The heat-reflecting part 15 is a heat-insulating sheet material and has a heat-reflecting function. By providing the heat-reflecting part 15 directly below the heating part 14, heat transfer to the back surface part 17 side is prevented. Thereby, the efficiency of heating the front surface part 11 is increased, energy is saved, and handling performance is improved. For this reason, it is preferable that the heat insulation performance of the heat-reflecting part 15 is lower than that of the heat storage part 12. Further, since the electromagnetic wave generating device 3 is provided directly below the heat-reflecting part 15, the influence of heat on the electromagnetic wave generating device 3 can be suppressed.

[0021] The back buffer part 16 is a sheet member provided by compressing cotton in order to reduce unevenness caused by the electromagnetic wave generating device 3. By compressing and increasing the density compared to the front buffer part 13, the durability on the back surface side can be enhanced and it can be made easier to handle.

[0022] The back surface part 17 is a sheet member made of polyurethane having substantially the same shape as the front surface part 11. Since the front surface part 11 and the back surface part 17 are water-resistant, it prevents malfunctions due to water wetting of the heating part 14 and the electromagnetic wave generating device 3 caused by sweat or the like. The heat storage part 12, the front buffer part 13, the heating part 14, the heat-reflecting part 15, and the back buffer part 16 described above are sewn along the edges of the front surface part 11 and the back surface part 17 together with the pocket part 2, and their positions are held.

[0023] As shown in FIG. 1 and FIG. 6, the pocket part 2 has a pocket body 21 for storing the stone material S inside and a gap part 22 between the pocket bodies 21. The gap part 22 is a part where the stone material S is not stored in the pocket part 2, thereby enhancing the flexibility compared to the pocket body 21. In the embodiment, the pocket part 2 is provided by a net part 201, a base part 202, and a large number of stone materials S sandwiched between the net part 201 and the base part 202. When the pocket part 2 is not provided, the gap part 22 is simply a part where the mat body 1 can be flexibly deformed, or a part that is easier to deform compared to other parts except the gap part 22 in the mat device X.

[0024] The mesh portion 201 covers the stone material S on top of the base portion 202 in the pocket body 21 and covers the base portion 202 in the gap portion 22. A portion of the stone material S is exposed through the gaps in the mesh portion 201, enhancing the infrared emission effect from the stone material S.

[0025] The base portion 202 is the part that holds the stone material S by being sewn to the mesh portion 201 to form the pocket body 21. The base portion 202 may be an independent sheet material, but it may be sewn to the surface portion 11 or the heat storage portion 12 so that it becomes the base portion 202. In addition, holes may be made in the surface portion 11 in the area where the pocket portion 2 is provided, and the pocket portion 2 may be sewn to that position to reduce the overall thickness of the mat device X and improve handling performance.

[0026] Stone material S is a stone that emits far-infrared rays and negative ions when heated. Examples of materials for stone material S include radium ore, tourmaline, germanium, terahertz ore, maifan stone, and loess, and it is preferable that at least two of these are blended and filled into the pocket body 21.

[0027] The stone pieces S are spherical with an outer diameter of approximately 0.5 mm to 3.0 mm, and it is preferable that all stone pieces S have approximately the same diameter. By making the stone pieces S small in diameter, the surface area of ​​the stone pieces S is increased, which can improve the efficiency of heat or far-infrared radiation emission. In addition, as the stone pieces S roll, their relative positions change, and their outer shape changes to suit the user lying down, improving usability.

[0028] The pocket body 21 is the portion filled with stone material S, as shown in Figures 6 and 7. The pocket body 21 is also provided with partitions 22 at predetermined intervals, which keeps the position of the stone material S within a certain range. This prevents uneven distribution of the stone material S in the mat body 1.

[0029] As shown in Figure 6(a), the pocket bodies 21 are provided across the entire width of the mat body 1 and are formed in multiples at regular intervals in the length direction. Furthermore, as shown in Figures 6(b) and 7, the pocket bodies 21 alternately have wide portions 211 in the width direction of the mat body 1 where the spacing between the pocket bodies 21 narrows and the width of the pocket bodies 21 widens, and narrow portions 212 where the spacing between the pocket bodies 21 widens and the width of the pocket bodies 21 narrows. The narrow portions 212 make it difficult for the stored stone materials S to move in the width direction, thereby suppressing uneven distribution of the stone materials S.

[0030] The void portion 22 is formed by stitching together the mesh portion 201 and the base portion 202, and is a part in which no stone material S is stored. The void portion 22 is provided between the pocket bodies 21 and has a folding void portion 221 that serves as an axis when the mat body 1 is folded, and a small void portion 222 that separates adjacent pocket bodies 21, both of which are provided along the entire width direction.

[0031] Here, the multiple pocket bodies 21 are divided into three groups by the folding gap 221: the head-side pocket group 21A located on the head side, the middle-side pocket group 21B adjacent to the head-side pocket group 21A, and the foot-side pocket group 21C located on the foot side. Within these groups, adjacent pocket bodies 21 are separated by small gaps 222.

[0032] Here, as shown in Figure 2, when viewed from the longitudinal direction of the mat body 1, the distance from the two folding gaps 221 to the nearest end is shorter than the length of the middle pocket group 21B, so that the ends do not protrude when folded. Accordingly, the middle pocket group 21B is made longer than the head pocket group 21A and the foot pocket group 21C. In this embodiment, the distance from the folding gap 221 to the nearest end is approximately the same for both the head and foot sides.

[0033] Furthermore, in this embodiment, when viewed along the length of the mat body 1, the length from the head-side pocket group 21A to the nearest end is longer than the length from the foot-side pocket group 21C to the nearest end, while the length of the head-side pocket group 21A is shorter than the length of the foot-side pocket group 21C. This improves the usability of the head-side pocket group 21A, which is easier to use than the foot-side pocket group 21C, and also reduces the overall weight. In other words, it ensures that there is enough space on the surface 11 to rest the head, and the user can choose to warm their head in the pocket section 2 or cool it in the surface section 11, thus improving usability.

[0034] The folding gap 221 is provided to be at least twice the width of the pocket body 21, so that the folding axis is at an acute angle and the mat body 1 does not bulge when folded. In addition, two folding gaps 221 are provided, and the width of each is greater than the overall thickness of the mat device X, enabling easy tri-folding. Furthermore, the folding gap 221 is at least larger than the width of the pocket body 21, preferably more than twice the width of the pocket body 21, so that the flexibility of the folding gap 221 is greatly increased compared to the area where multiple pocket bodies 21 are arranged, making it easier to make folds in the folding gap 221.

[0035] The small gap portion 222 enhances the overall flexibility of the mat body 1 and improves handling performance by creating a predetermined gap between two adjacent pocket bodies 21. The small gap portion 222 is provided to be at least narrower in width than the folding gap portion 221. As shown in Figure 6, the small gap portion 222 is formed by stitching connecting the mesh portion 201 and the base portion 202, creating a wide portion 211 and a narrow portion 212. The small gap portion 222 may also be provided in the longitudinal direction of the mat body 1.

[0036] The wide portion 211 is the part of the pocket body 21 formed between the sutures of the curved small gaps 222. That is, as shown in Figure 6 and Figure 7(a) which shows the A-A' cross section of Figure 6, the width of the gaps is narrow because the small gaps 222 are curved sutures, and the width of the pocket body 21 is wider as a result. Since the shape and arrangement in the width direction of adjacent small gaps 222 are substantially the same, the curves of the small gaps 222 are adjacent in the length direction of the mat body 1, and the wide portion 211 becomes wider. Note that the small gaps 222 that form the wide portion 211 may be straight lines, or they may be surfaces with a smaller area than the small gaps 222 that form the narrow portion 212.

[0037] The narrow portion 212 is the part of the pocket body 21 formed between the seams of the planar small gaps 222. That is, as shown in Figure 6 and Figure 7(b), which shows the B-B' cross section of Figure 6, the small gaps 222 are seams made of surfaces, so the width of the gaps becomes wider, and the width of the pocket body 21 becomes narrower accordingly. Since the shape and arrangement in the width direction of adjacent small gaps 222 are substantially the same, the surfaces of the small gaps 222 are adjacent in the length direction of the mat body 1, and the narrow portion 212 becomes even narrower. Although the small gaps 222 forming the narrow portion 212 are circular, any shape is acceptable as long as it has length in the length direction of the mat body 1. Furthermore, since stone material S tends to accumulate in the narrow portion 212, the height of the pocket body 21 is higher in the narrow portion 212 compared to the wide portion 211. This creates irregularities on the mat body 1 due to the stone material S, increasing the contact area with the user and improving heating performance.

[0038] The void portion 22 adjacent to the narrow portion 212 forms a surface with multiple V-shapes arranged inside a circle, as shown in Figure 6(b), and is provided continuously with the curved void portion 22 adjacent to the wide portion 211. The spacing between the V-shapes is the same as or smaller than that of individual stone pieces S. When stitching with the stone pieces S in place, the stone pieces S are separated by the curved stitching, and then the closely spaced V-shapes are stitched together, thereby increasing strength and preventing the stone pieces S from entering the void portion 22. Furthermore, this stitching method allows for continuous stitching, reducing manufacturing costs. The ends of the folded void portion 221 can also be formed by stitching in a similar shape to reduce manufacturing costs.

[0039] The electromagnetic wave generator 3 generates electrical stimulation and magnetic fields to further improve the user's blood circulation and relieve stiffness. The electromagnetic wave generator 3 comprises multiple flat coils arranged at predetermined intervals. These flat coils are supplied with a specific low-frequency pulsed current from the control unit 4, generating a pulsed electromagnetic field (PEMF) that promotes cell repair.

[0040] As shown in Figures 4 and 5, the electromagnetic wave generator 3 is positioned and fixed so as to avoid the folding gap 221 in a plan view, making folding easy. In this embodiment, the pocket body 21 is divided into three groups, with one located directly below the head-side pocket group 21A, two directly below the middle-side pocket group 21B, and one directly below the foot-side pocket group 21C. When viewed from the length direction of the mat body 1, two are located in the middle-side pocket group 21B at positions away from the center. By providing multiple pockets in this way, the effects of electromagnetic waves can be applied to the entire body.

[0041] Furthermore, the electromagnetic wave generators 3 are positioned so as not to interfere with each other in a plan view when folded. Preferably, when folded, the electromagnetic wave generators 3 located directly below the head pocket group 21A and the foot pocket group 21C are positioned between the two electromagnetic wave generators 3 located directly below the middle pocket group 21B in a plan view. This reduces the thickness when folded. Also, by making the electromagnetic wave generators 3 rectangular parallelepipeds, the orientation of their placement is fixed, and the position of the folding gap 221 can be clearly designed, so that the points where bending occurs can be concentrated in the intended locations.

[0042] It is preferable to use a small and lightweight electromagnetic wave generator 3. This makes it easy to fold and reduces the overall weight even if multiple electromagnetic wave generators 3 are installed.

[0043] Furthermore, in order to appropriately deliver the magnetic field from the electromagnetic wave generator 3 to the user, it is preferable to use high-performance plastic instead of metal for the heat storage section 12 and the heat reflection section 15. Alternatively, it is preferable to have holes in the part from which electromagnetic waves are emitted from the electromagnetic wave generator 3.

[0044] The control unit 4 is the part that supplies power to the heating element 141 and the electromagnetic wave generator 3. The control unit 4 includes a controller 41 that controls the power and a connection unit 42 that supplies the power adjusted by the controller 41 to the mat body 1.

[0045] The controller 41 converts power obtained from a household AC power source into a DC current to supply to the heating element 141 and a pulsed current to supply to the electromagnetic wave generator 3. This enhances safety. Furthermore, the controller 41 can be improved by having at least a function to adjust the voltage supplied to the heating element 141 and a function to switch the pulse on / off and pulse frequency supplied to the electromagnetic wave generator 3. It may also have a timer function.

[0046] The control unit 4 may include a thermostat, and the temperature of the heating unit 14 can be changed within a range of at least 40 to 60 degrees Celsius. The pulse frequency can also be changed within a range of 1 to 25 Hz, and can be changed in steps at frequencies of 3 Hz, 7.8 Hz, 10 Hz, and 23 Hz.

[0047] The connecting portion 42 is provided at the foot end of the mat body 1, at the end in the width direction. The entire connecting portion 42 is located inside the mat body 1, preventing it from protruding when folded and improving storage.

[0048] The method of implementing this invention will be described in detail below with reference to the drawings. This invention is implemented by a user who warms their body with the mat device X, folds it, and carries it. Furthermore, the implementation method shown below is just one example, and the method of implementation is not limited to this, and the order may be different.

[0049] First, the user connects the control unit 4 to the mat body 1. Next, they unfold the mat device X, place a towel on top of it, and lie down on it. Then, the controller 41 adjusts the temperature and PEMF to achieve a comfortable user experience.

[0050] Next, the user folds the mat device X. At this time, the folding gap 221, which is more flexible than the part where the group of pocket bodies 21 is provided, can be easily folded.

[0051] The user folds the foot pocket group 21C and the middle pocket group 21B so that they overlap, and then positions the back surface 17 of the foot pocket group 21C and the head pocket group 21A so that they overlap. This sandwiches the connecting part 42 between multiple cushioning parts, reducing the thickness of the connecting part 42, making it more compact, and increasing the durability of the connecting part 42.

[0052] Furthermore, the user can further reduce the volume when folded by folding the pocket body 21 into the small gaps 222 that are provided along the entire width of the mat body 1.

[0053] As an example of the modification, multiple folding gaps 221 are provided, each having a width greater than the thickness of the mat device X. This allows the folding gaps 221 to cover the thickness of the mat device X, enabling it to be folded into three sections and improving its folding performance.

[0054] Furthermore, the electromagnetic wave generator 3 is positioned between multiple buffer layers, which enhances the device's durability and user experience. The user experience is further improved by sandwiching the electromagnetic wave generator 3 between the front buffer layer 13 and the back buffer layer 16. To further enhance the user experience, it is preferable that the combined thickness of the front buffer layer 13 and the back buffer layer 16 is greater than that of the electromagnetic wave generator 3.

[0055] Furthermore, the gap portion 22 includes a smaller gap portion 222 that is narrower than the folding gap portion 221, and the smaller gap portion 222 is provided along the entire width direction, which increases the flexibility of the mat body 1 in the length direction even in parts where the folding gap portion 221 is not provided, making it easier to handle. Also, if the smaller gap portion 222 and the pocket body 21 are provided at regular intervals, the thickness when folded can be further reduced by inserting the pocket body 21 into the smaller gap portion 222.

[0056] Furthermore, the pocket body 21 includes a wide portion 211 and a narrow portion 212 along the length of the mat body 1. The wide portion 211 increases the overall rigidity of the pocket body 21 and guides the folded portion into the folded gap 221. In addition, the narrow portion 212 can be used to secure the stone material S and prevent it from shifting.

[0057] Furthermore, the heating section 14 includes a linear heating element 141, and the heating element 141 has multiple parallel sections 142 that are parallel to the folding direction of the folded gap section 221. Since the heating element 141 is less likely to bend in the parallel sections 142, breakage due to bending is prevented, and durability is increased.

[0058] Furthermore, by including a sheet-like heat storage section 12 that covers the heating section 14, surface heating becomes possible even if the density of the heating section 14 is low, reducing temperature unevenness in the surface section 11 and pocket section 2. Reducing the density of the heating section 14 contributes to weight reduction and portability.

[0059] Furthermore, multiple electromagnetic wave generators 3 are installed inside the mat body 1, and their parallel arrangement reduces unevenness in electromagnetic waves, making it easier to obtain the effects of the electromagnetic wave generators 3 throughout the entire body. In addition, because it is a rectangular prism, it is easy to control the position in which it can be folded. [Explanation of symbols]
