Japanese Utility Model Publication No. 6-58944 Japanese Utility Model Publication No. 6-31737 JP-A-8-206165

  Since the conventional massage device requires protrusions, the structure is complicated, and it takes time and money to manufacture. For example, in order to connect a protrusion to a rod portion, a screw hole is formed in the rod portion, a screw protrusion is formed in the protrusion, and the screw protrusion is screwed into the screw hole, whereby the protrusion is attached to the rod portion. It was connected.

  Since the vertical bar of the above-mentioned conventional walking stick is linear, the vertical bar cannot be gripped, and even if it is gripped, the gripped hand slips and is dangerous. Especially when the walking stick is wet, such as on a rainy day, this danger has increased.

  In order to achieve the above-mentioned object, the present invention has a substantially sinusoidal shape or a substantially cosine curve shape having a length of approximately one cycle or more, and includes a bar portion that applies a portion of the sinusoidal shape or cosine curve shape to the body. It was.

  In addition, the present invention includes a rod portion having a substantially sine curve shape or a substantially cosine curve shape having a length of approximately one cycle or more, and a grip portion connected to the upper end of the rod portion.

  Thereby, a massage effect can be taken out only by touching the convex bay part of the sine curve shape or cosine curve shape of the massage device to the body. Moreover, the concave bay part of a sine curve shape or a cosine curve shape can also be applied to the convex part or flat part of the body, and massage can be performed not only in the convex bay part of the curved part but also in the concave bay part.

  In addition, this makes it possible to curve the vertical bar of the walking stick, so that even if the vertical bar is gripped, it does not slide downward, and even if the vertical bar is gripped by hand, there is no danger and it is safe.

(1) Massage tool 1
1 and 2 show the side surface of the massage device 1. This drawing shows only a part of the massage device 1 and is actually continuous up and down. The massage tool 1 is made of wood, and is made of, for example, a laminated material of tammo. In addition, other woods and strips may be used, and stainless steel, titanium, aluminum, other metals, resins, ceramics, concrete, or a composite thereof may be used. In this case, a hard material among these may be used at the center, and a soft material having a large or small friction coefficient may be coated on the surface.

  The rod portion 2 of the massage tool 1 has a columnar shape, and the outer diameter (thickness) is, for example, 34 mm, which is an optimal thickness for an adult to hold. When the rod portion 2 is cylindrical, the inner diameter is, for example, 28 mm. If the massage tool user is an adult or disabled person, the external shape will be changed accordingly. In addition, the rod portion 2 may have a cylindrical shape, a prismatic shape, a rectangular tube shape, a plate shape, or the like.

  The bar portion 2 has a sinusoidal shape (including a “cosine curve shape”, the same applies hereinafter), the period of the sine wave is 283 mm at the center of the bar portion 2, and the amplitude of the sine wave is the bar portion 2. 26 mm at the center. The radius of curvature of the sine wave is 93 mm at the center of the rod portion 2, 110 mm at the outside of the rod portion 2, and 76 mm at the inside of the rod portion 2.

  In the sine wave-shaped unevenness of the rod portion 2, a portion protruding upward in FIG. 1 is referred to as a convex bay portion 3, and a portion protruding downward (portion recessed to the right) is referred to as a concave bay portion 4. The right half of the convex bay part 3 is the right convex bay part 3a, the left half of the convex bay part 3 is the left convex bay part 3b, the right half of the concave bay part 4 is the right concave bay part 4a, and the left half of the concave bay part 4 is It is called left concave bay part 4b.

  Between the peak and valley of this sine wave, that is, between the convex bay part 3 and the concave bay part 4, in other words, between the left convex bay part 3b and the right concave bay part 4a, and between the right convex bay part 3a and the left A straight line portion 6 is formed between the concave bay portion 4b. The length of the straight line portion 6 is 50 to 150 mm, for example, 93 mm or 130 mm. The length of the straight line portion 6 is changed depending on the use application / use state of the massage tool 1. Thereby, the length of the grip which makes it difficult to slip can be changed.

  The length of the sine wave of the rod portion 2, that is, the number of cycles is approximately 2 cycles, but the length of 1 cycle, the length of 1 cycle or more, the length between 1 cycle and 2 cycles, 2 cycles May be a length of 2 cycles or more, a length of 2 cycles to 3 cycles, or a length of 3 cycles or more. The convex bay part 3 and / or the concave bay part 4 of the rod part 2 curved to the sine wave is applied to the body to perform massage / acupressure.

  Grip portions 5 and 5 are formed at both ends of the rod portion 2. In the grip portions 5 and 5, the bar portion 2 that is curved in a sinusoidal shape is curved and extends straight along the longitudinal direction of the entire massage tool 1. Massage / acupressure is performed by grasping the grips 5 and 5 with both hands or one hand. The grips 5 and 5 may be omitted.

(2) Significance of each dimension of the massage device 1 As described above, the length of the period of this sine wave is 283 mm, and this length is substantially equal to the distance between the centers of the left and right thighs of an adult. Is approximately equal to the distance between the approximate center of the lower leg, the approximate center of the left and right shoulders, the distance between the left and right nipples, the approximate center of the left and right back muscles, and the approximate center of the left and right hips.

  Thereby, these portions can be massaged / acupressured simultaneously in parallel with the pair of convex bay portions 3 and 3 of the rod portion 2 at the same left and right portions of the body. In addition, if the person to whom massage / acupressure is applied changes, such as a man, a woman, an adult, or a child, the length of the sine wave and other dimensions are changed accordingly. Such massage may be performed on the left and right parts of the waist, left and right upper arms, left and right forearms, left and right buttocks, left foot right hand, left foot right foot, and the like by changing the length of the cycle.

  However, the sinusoidal curvature characteristics can be accommodated and absorbed even with slight changes in body size. This is because the sinusoidal curve characteristic does not protrude like a protrusion but curves and protrudes gently or dents.

  As described above, the radius of curvature of the sine wave is 93 mm at the center of the rod portion 2, 110 mm at the outside of the rod portion 2, and 76 mm at the inside of the rod portion 2, and this curvature curve is the surface of the adult thigh. Is approximately equal to or less than the curvature curve of the adult, and is approximately equal to or less than the curvature curve of the back surface of the adult lower leg, and is approximately equal to or less than the curvature curve of the back surface of the adult neck.

  This is convenient for massage / acupressure on the back of the thigh, the lower leg, and the back of the neck. When the radius of curvature inside the rod portion 2 of the massage rod 1 is smaller than the radius of curvature of the massaged portion, massage / acupressure can be performed by dispersing force over the entire portion. When the radius of curvature inside the rod portion 2 of the massage rod 1 is larger than the radius of curvature of the massaged part, massage / acupressure can be performed by concentrating the force at the center of the part.

  When the radius of curvature of the part to be massaged is substantially equal to the radius of curvature inside the rod portion 2 of the massage rod 1, massage / acupressure can be performed in the intermediate state between dispersion and concentration. Which one to choose depends on the taste of the person receiving the massage.

    In general, the radius of curvature of the sinusoidal shape inside the bar 2 is preferably 0.5 to 2 times the radius of curvature of the surface of the part to be massaged from the viewpoint of touch, pleasure, pain, etc. Desirably, it is 0.6 times to 1.7 times, more desirably 0.7 times to 1.4 times, and even more desirably 0.8 times to 1.1 times.

  However, in some cases, the radius of curvature of the surface of the part to be massaged by a human may be 0.4 to 2.5 times, 0.3 to 3 times, 0.2 to 4 times, and so on. In addition, if the human being massaged / shiatsu changes the size of the body, such as a man, a woman, an adult, or a child, the radius of curvature and other dimensions are changed accordingly. Such a massage may be performed on the upper arm, forearm, buttocks, armpit, shoulder, hand, foot, waist, etc. by changing the radius of curvature.
