Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a back shiatsu tool that stretches the back muscles and acupressures the sides of the spine with the weight of the body.

[0002]

[Prior art]

 FIG. 6 is a perspective view showing a conventional back shiatsu tool. In this back shiatsu tool, a plurality of protruding plates 62 are provided at regular intervals between the left and right side plates 61 and 61a, the degree of curvature of which is gradually increased from the front side to the rear side, and are orthogonal to the side plates. It is arranged in the direction. On the upper surface of the protruding plate 62, two right and left protruding portions 63, 63 are integrally provided so as to correspond to positions where both sides of the spine of the human body are in contact with each other.

[0003] The upper body of the human body is supported by one spine. Therefore, the spine is always subjected to a large load. As a result, unpleasant symptoms such as distortion of the back muscles or stiffness of the back muscles are exhibited.

[0004] When using the back shiatsu tool, the back shiatsu tool is placed on a flat floor surface, and in a supine position, the waist is positioned toward the front with a small degree of curvature (low rise from the floor surface). Sleep. Since the back shiatsu tool has a curved structure that matches the back, that is, a plurality of protruding plates are set and arranged in a curved shape, the back can be stretched simply by placing the back. That is, the extension of the back muscle can be promoted, and the blood circulation can be promoted. In addition, the prongs arranged in the center two rows by their own weight press both sides of the spine, so that the muscles of the spine are rubbed and relaxed by finger pressure and stiffness is eliminated.

[0005]

[Problems to be solved by the invention]

 In the above-mentioned conventional back shiatsu tool, the protruding portion is of a fixed type integrally continuous with the protruding plate, and the protruding length of each protruding portion is also constant. Therefore, the pressing force of the protrusion acting on each part of the back is the same. However, depending on the part of the human body, that is, depending on the degree of stiffness of the muscles, a strong acupressure (pressing) effect or a weak acupressure (pressing) effect may be required, and there is a disadvantage that this request cannot be met. .

[0006] Further, the conventional back shiatsu tool has a width and a length corresponding to the length from the shoulder to the waist (buttock), which is a normal adult physique, with the back on the back. . And it is a molded product with the integrated width and length. Therefore, the equipment is large and cannot be used for storage when not in use, and the packaging package requires a large box and the transportation cost is high. Further, as a material for forming a product requires a long material, a short and inexpensive material cannot be used, so that there is a disadvantage such as a rise in product cost.

[0007] Furthermore, the respective protruding discs arranged at predetermined intervals are arranged orthogonally to the spine. As a result, the weight acts as a concentrated load on the connection between each of the lugs and the side plates, resulting in disadvantages such as a low load resistance and a short product life.

The present invention solves the above-mentioned problems, and can be transported and stored in a compact state, and is an inexpensive back shiatsu tool capable of selectively applying an appropriate finger pressure according to a part. The purpose is to provide.

[0009]

Means and Action for Solving the Problems

 To achieve this purpose, the back shiatsu tool of the present invention has the following configuration. The back shiatsu tool consists of a pair of separable front and rear halves consisting of a front half with a small degree of curvature and a rear half with a large degree of curvature, and each half has its base end fixed to both ends of the substrate. A curved outer support plate with a connecting dovetail at the tip, a base fixed at the center of the substrate, a connecting dovetail at the tip, and a fixed spacing on the top surface. It is characterized by comprising a curved two-row central support plate portion having a plurality of pressing projections protrudingly arranged.

[0010] In the back shiatsu tool having such a configuration, the patient lies on his back with the waist positioned on the front half side with a small curvature and the shoulder positioned on the rear half with a large curvature. Simply by resting the back, the back muscles are stretched by the curved structure of the tool. In addition, the pressing projection presses the acupoints (so-called acupoints) on the meridians located on both sides of the spine in acupressure form by its own weight. This relieves stiffness in the muscles of the back.

This back shiatsu tool is of an assembling type in which a pair of halves is separable. In other words, it is composed of four back bearing plates (two center bearing plates with pressing projections on the upper surface and two outer bearing plates located on both sides) protruding from the substrate in the form of teeth of a comb. The front half and the rear half forming a pair with the front half are detachably connected to each other by dovetail joints at the tips of four back support plates. Therefore, the pair of halves can be divided (separated) when not in use or when transported. By polymerizing the separated halves in a staggered manner, the length can be reduced to half the length of the connected state. Also, since the length of the support plate portion of each half is short, it can be made of inexpensive short wood, and the cost can be reduced.

Each of the pressing projections provided on the upper surface of the central support plate is removably fitted into a fitting hole provided on the upper surface of the central support plate. Further, a plurality of types of shaft lengths of which the protruding length in the upward direction varies in length and short length when the pressing protrusion is fitted in the fitting hole portion are prepared. Therefore, a pressing protrusion having a large protruding length (a protruding shaft having a long shaft length) is fitted into the fitting hole at a site requiring a stimulus with a large acupressure, and a stimulus with a small acupressure is required. Select the fitting hole to fit the pressing protrusion with a large or small protrusion length, such as fitting a pressing protrusion with a short protrusion length (a short shaft length protrusion) into the fitting hole. The desired pressing force (finger pressure) can be applied to a desired portion by fitting the. That is, the finger pressure can be changed depending on the region.

[0013] Furthermore, the four back support plates are arranged in a direction parallel to the spine, and the upper surface of each continuous support plate is completely in contact with the back. Therefore, the weight is received by the entire length of the back support plate portion, resulting in a dispersed load, a high load bearing capacity and a long product life.

[Embodiment of the invention]

 Hereinafter, a specific embodiment of the back shiatsu tool according to the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing a back shiatsu tool according to the present invention. The back shiatsu tool A is composed of a pair of front and rear halves 1 and 2 that can be separated. That is, the back acupressure body A is composed of the first half 1 having a small degree of curvature and the second half 2 having a large degree of curvature.

The first half 1 and the second half 2 are both formed using hard and tough wooden boards, such as beech wood. The front half (front half) 1 includes a substrate 11 which is a rectangular flat plate, and four comb-shaped back support plates 12, 12a, 13, 13a each having a base end fixed to the substrate 11. Outer support plate portions 12 and 12a fixed to the left and right end portions of the substrate 11, respectively, and central support plate portions 13 and 13a fixed to the center portion of the substrate 11, respectively, have a rising height from the substrate 11. That is, the degree of curvature is the same, and the degree of curvature is set to be small in both cases.

The four support plate portions 12, 12 a, 13, and 13 a project from the substrate 11 in a direction orthogonal to the substrate 11 at a certain interval. In particular, when the spine is located in the space, the central support plate portions 13 and 13a are arranged on both sides of the spine, that is, on both sides of the spine (meridians of the human body) when the spine is positioned in the space. ) Is set.

Further, a dovetail portion 15 having a stepped shape is formed at the tip of each of the support plate portions 12, 12a, 13, 13a. Each dovetail portion 15 is provided with a connecting through hole 17.

A plurality of fitting holes 16 are formed on the upper surfaces of the central support plate portions 13 and 13a at regular intervals in the longitudinal direction.

The rear half (rear half) 2 includes a substrate 21 that is a rectangular flat plate, and four comb-shaped back support plates 22, 22 a, 23, and 23 a having bases fixed to the substrate 21. Consists of The outer supporting plate portions 22 and 22a fixed to the left and right ends of the substrate 11, respectively, and the central supporting plate portions 23 and 23a fixed to the central portion of the substrate 11, respectively, have a rising height from the substrate 11. That is, the degree of curvature is the same, and the degree of curvature is set to be large in both cases (the degree of curvature is set to be larger than that in the first half 1).

The four support plate portions 22, 22 a, 23, and 23 a project from the substrate 11 in a direction orthogonal to the substrate 11 at a certain interval. A stepped dovetail joint 25 is formed at the tip of each of the support plates 22, 22a, 23, and 23a. Each dovetail portion 15 is provided with a connecting through hole 27.

A plurality of fitting holes 26 are formed on the upper surfaces of the center support plate portions 23 and 23a at regular intervals in the longitudinal direction.

As shown in FIG. 3, a pair of separable halves (a front half 1 and a rear half 2) 1, 2 correspond to the respective back support plate portions 12 and 22, 12 a and 22 a, 13. By joining the dovetail joints (tip portions) 15 and 25 of the connection dowels 17 and 27, the connecting through holes 17 and 27 communicate with each other. The thumb screws 4, washers 41, and nuts 42 are inserted into the communication holes 17, 27 from below, and the corresponding rear support plates are connected and fixed, and the front half 1 and the rear half 2 are connected to each other. (See FIG. 2).

When the front half 1 and the rear half 2 are connected to each other, the back acupressure body A has a curved structure with a small curvature at the front and a large curvature at the rear. It is set to correspond to the back. In other words, it has a curved structure that allows the spine to elongate.

The hole diameters and hole depths of the fitting holes 16 and 26 on the upper surfaces of the central support plate portions 13, 23, 13 a, and 23 a are set to be constant. On the other hand, the plurality of pressing projections 3 are fitted and provided so as to be able to be fitted and removed.

As shown in FIG. 2, the pressing projection 3 has a lower portion having a diameter that allows the pressing projection 3 to be smoothly fitted into and removed from the fitting holes 16 and 26. A plurality of types of the pressing projections 3 are prepared. For example, as the pressing projection 3, a projection 31 having a short shaft length, a projection 32 having a long shaft length, a projection 33 having a special shape whose upper part has a large diameter or a small diameter, or an upper part. A magnet projection 34 having a permanent magnet 34a at its (tip) portion, or a magnet whose upper portion is covered with a rubber cap. Pressing protrusions 3 of various lengths / shorts and various shapes are prepared, and the selected pressing protrusions (31, 32, 33, 34) 3 are fitted into the plurality of fitting holes 16 and 26. .

In the back shiatsu tool having such a configuration, as shown in FIG. 4, the waist X is positioned on the front half 1 having a small curvature, and the shoulder Y is positioned on the rear half 2 having a large curvature. I lie on my back with my position. Simply resting on the back stretches the back muscles due to the curved structure of the tool. Further, each pressing projection 3 presses acupoints (so-called acupoints) on meridian lines located on both sides of the spine with a finger pressure in accordance with own weight. This relieves stiffness in the muscles of the back.

This back acupressure tool has a pair of halves 1 and 2 that can be separated and is of an assembling type. As shown in FIG. 3, the front half 1 and the rear half 2 can be divided by removing the thumb screws 4 respectively. As shown in FIG. 5, the tooth-shaped back support plate portion of each comb, for example, the outer support plate portion 12 of the front half 1 is connected to the outer support plate portion 22 of the rear half 2 and the center support plate 23. It is inserted into the space (space) and the back support plates are staggered at the insertion position, so that the height (thickness) is almost the same as that in the continuous state and half the length of the continuous state. It can be disassembled and stored.

Therefore, each of the halves 1 and 2 is short, and can be made of inexpensive short wood, so that the product cost can be reduced. In addition, since it can be stored compactly, the product package cannot be reduced in size and the transportation cost is low.

The pressing projection 3 provided on the upper surface of the central support plate portion is removably fitted to the fitting holes 16 and 26 provided on the upper surface of the central support plate portion. Therefore, a desired pressing projection 3 can be selected and fitted into the fitting holes 16 and 26.

For example, in the case where the pressing protrusion 32 having a large protrusion length (a protrusion having a long shaft length) 32 is fitted into the fitting holes 16 and 26, a strong pressing force is generated due to the long protrusion length. Acts on the back. Conversely, a pressing protrusion (short shaft length short) 31 having a small protruding length is fitted into the fitting holes 16 and 26 at a site where stimulation with low acupressure is desired. Further, when it is desired to apply a magnetic force to the acupoints (acupoints) on the back, the magnet projections 34 are fitted. In addition, when pain is felt on the back due to the pressing force, the pressing protrusion 3 having a rubber cap on the upper portion is fitted, and the pressing protrusion 3 is appropriately selected as desired, so that the back can be selected. The corresponding pressing force can be obtained for each part.

Further, the four back support plates 12 (22), 12 a (22 a), 13 (23), and 13 a (23 a) are arranged in a direction parallel to the spine. Therefore, the weight is received over the entire length of the back support plate, resulting in a dispersed load, a large load resistance and a long product life.
