Utility Model Registration No. 3000211 Japanese Utility Model Publication No. 54-43088

  The conventional body massage device has the following problems. According to the portable massage device according to Patent Document 1 and Patent Document 2, the plurality of needle-like protrusions protruding from the distal end portion of the main body are arranged in a restrained state in which they cannot move with a certain interval, All the needle-like protrusions are provided in a fixed state so as to have the same height. As a result, the lines of magnetic force emitted from the tip of each needle-like protrusion form a uniform magnetic field and act on the body in a dispersed state.

  Therefore, depending on the shape of the body part to be massaged, it was impossible to apply a magnetic force by pressing the tip portions of all the needle-like protrusions equally against the part. In addition, it was not possible to use it by concentrating the magnetic force on a specific part of the body.

In addition, since the needle-like projections are arranged in a restrained state, if the needle-like projections are strongly pressed against the body, the stimulation is too strong, and there is a risk that the user may feel pain or injure the body.
Furthermore, a structure that adjusts the protruding amount of the needle-like protrusions and a structure that softens the stimulus by the needle-like protrusions by a spring are disclosed, but all the needle-like protrusions move in the axial direction uniformly, and more However, depending on the part of the body, the stimulation was too strong or too weak.

  The present invention has been made on the basis of such points, and the object of the present invention is to effectively concentrate the magnetic force efficiently by freely changing the position of the acupressure point according to the body part to be applied. It is possible to obtain an effective magnetic massage effect, and by freely changing the interval and height of action of each acupressure point depending on the body part to be applied, it is moderate without causing pain when pressed against the body An object of the present invention is to provide a body massager having a simple structure capable of obtaining a gentle acupressure massage effect.

In order to achieve the above object, a body massage device according to claim 1 of the present invention comprises a main body casing,
A magnet that generates a magnetic force of a predetermined magnitude, provided in a fixed state with the first magnetic pole surface facing the distal end side at the base end portion of the main body casing;
The base end portion of the main body casing is provided in a state of being fitted inside the front end portion, and the base end surface is in contact with the first magnetic pole surface of the magnet, and the front end surface is separated from the front end surface of the main body casing. A support ring made of a magnetic material provided in a protruding state;
Made of a plurality of magnetic bodies that are housed in the support ring, the base end surface of which is in contact with the first magnetic pole surface of the magnet, and the tip end portion of which protrudes from the tip end surface of the support ring. Acupressure protrusions,
Between the support ring and the acupressure protrusions and between the acupressure protrusions, gaps are formed at predetermined intervals for applying a magnetic force thereto, and the plurality of acupressure protrusions are formed in the support ring due to the presence of the gaps. A simple restraint state due to magnetic force is formed and held, and each acupressure protrusion is provided in a state where it can freely move while repelling each other,
The acupressure protrusion is a nail-like body having a base end surface and a pointed end in a range where the distal end portion gives moderate stimulation,
The support ring includes an outer tube fitted into the second housing portion of the main body casing and an inner tube fitted into the outer tube, and the outer tube 21 and the inner tube 23 are in contact with each other. The outer tube is formed so that the height of the outer tube is higher than the height of the inner tube .

And the following effects are acquired by the said means. That is, in the present invention, a gap of a predetermined interval is formed between the support ring and the acupressure protrusion and between the acupressure protrusions so as to apply a magnetic force thereto. A simple restraint state is formed by the magnetic force from the magnet.
Specifically, the proximal end surface of each acupressure protrusion is held by a magnetic force by being directly attracted to the first magnetic pole surface of the magnet, and the distal end portion of the acupressure protrusion disposed on the inner peripheral surface side of the support ring is It is attracted and held by the support ring magnetized by the magnet. Moreover, each acupressure protrusion repels each other, and is hold | maintained in the state in which the clearance gap was formed between adjacent acupressure protrusions. Therefore, the holding posture of the acupressure protrusion is stabilized by holding at these plural points by the magnetic force.

The holding state of the acupressure protrusion is not fixed, and changes as needed depending on the shape of the body part to be applied, the pressing method of the acupressure protrusion, or the movement in the direction along the body part to be applied. Therefore, the acupressure protrusion can freely move within the gap formed in the support ring, and each acupressure protrusion can freely move the position of the acupressure point according to the shape of the body part. By changing the magnetic force, the magnetic force can be concentrated efficiently, and a strong magnetic massage effect can be obtained.
In addition, since the distance between the acupressure points and the height of action of each acupressure protrusion automatically change depending on the shape of the body part to be applied, etc., all the acupressure protrusions act on the body part, and the effect It becomes possible to obtain a typical acupressure massage effect.

Further, when the acupressure protrusion is constituted by a nail-like body having a flat base end surface and a pointed end in a range in which the distal end gives a moderate stimulus, the contact area of the acupressure protrusion with respect to the first magnetic pole surface of the magnet is small. Since it becomes large, the magnetic force of the magnet is efficiently transmitted to the acupressure protrusion, and the necessary magnetic force can be obtained.
Moreover, when the tip of the acupressure protrusion is pressed against the body, a moderate acupressure massage effect with moderate stimulation can be obtained without damaging the body or feeling pain.

  In addition, if the support ring has a double tube structure with an outer tube and an inner tube, and the height of the outer tube is higher than the height of the inner tube, the free end of the acupressure protrusion can be freely moved. In this state, the contact area between the base end face of the support ring and the first magnetic pole face of the magnet can be increased, and a stronger magnetic force can be applied to the support ring.

The support ring 19 made of a magnetic material is provided in a state in which the front end surface 27 protrudes from the front end surface 8 of the main body casing 3, and the base end surface 33 is accommodated in the first ring of the magnet 15. A plurality of acupressure protrusions 31 made of a magnetic material provided in contact with the magnetic pole surface 11 and having a tip portion 35 protruding from the tip surface 27 of the support ring 19; Thus it has been basically formed.

  A gap 39 is formed between the support ring 19 and the acupressure protrusions 31 and between the acupressure protrusions 31 so as to apply a magnetic force to them. The protrusions 31 are formed and held in a simple constrained state by magnetic force in the support ring 19 and are provided in a state where the acupressure protrusions 31 can freely move while repelling each other. It is said.

And in this Embodiment, the main body casing 3 with the handle | steering-wheel 9 operated with the handle | steering-wheel 9 at the time of use is shown in figure. Specifically, a hole 41 having a large diameter on the proximal end portion 5 side and a small diameter on the distal end portion 7 side is formed in the center of the truncated cone-shaped casing 4 in the axial direction Z. The hole 41 on the part 5 side is a first housing part 43 for housing a magnet 15 to be described later, and the hole 41 on the tip 7 side having a small diameter is a second housing part for housing a support ring 19 and acupressure protrusion 31 to be described later. 45.
Moreover, the main body casing 3 is formed by attaching a scoop-shaped handle 9 as an example so as to close the opening on the base end face 6 side of the first accommodating portion 43. In addition, as a material of the main body casing 3, a hard plastic material is applicable as an example.

As the magnet 15, a short cylindrical magnet can be applied as an example of being accommodated in the first accommodating portion 43. Further, as the magnet 15, a neodymium magnet of about 1200 gauss can be applied as an example, and when the neodymium magnet is used, it is possible to obtain a necessary magnetic force even when a small magnet is used. .
Specifically, even if the main body casing 3 in the posture shown in FIGS. 1 to 3 and 5 is turned upside down and the second housing portion 45 is faced down, the acupressure protrusions 31 are formed from the second housing portion 45. The magnet 15 is used that can generate a magnetic force having a magnitude that can be expected to produce a desired magnetic massage effect during use, without being dropped, and being simply constrained by the above-described magnetic force.
In the illustrated embodiment, the magnet 15 is provided in an arrangement in which the first magnetic pole surface 11 located on the upper surface in FIG. 5 is an N pole and the second magnetic pole surface 13 located on the lower surface in FIG. It has been.

  Further, as shown in FIG. 6, the height of the outer tube 21 is formed so as to be higher than the height of the inner tube 23. By configuring in this way, the distal end portion of the acupressure protrusion 31 described below is formed. 31, a free floating range of 31 can be secured, and the contact area between the base end face 25 of the support ring 19 and the first magnetic pole face 11 of the magnet 15 can be expanded to apply a stronger magnetic force to the support ring 19. It is possible.

The acupressure protrusion 31 is configured as an example of a nail-like body having a base end surface 33 and a pointed end in a range where the distal end portion 35 gives a suitable stimulus.
In addition, the pointed shape here is not an extreme pointed state in which the body is damaged or painful when pressed against the body, but in a range in which moderate stimulation can be given as the body massager 1. It means a pointed state.
The support ring 19 is made of a magnetic material such as iron. When the inner tube 23 has an inner diameter of about 10 mm and the acupressure protrusion 31 has a diameter of about 2 mm, the support ring 19 is shown in FIG. As shown in FIG. 7, or as shown in FIG. 7B, seven acupressure protrusions 31 can be accommodated in the support ring 19.

Then, compared to the case where eight acupressure protrusions 31 are accommodated in the support ring 19 as shown in FIG. 7A, the seven acupressure protrusions 31 are provided in the support ring 19 as shown in FIG. When accommodated, the distance between adjacent acupressure protrusions 31 is increased and the gap 39 is increased, so that the free range of the acupressure protrusions 31 is expanded, and a wider range can be freely moved.
On the other hand, when eight acupressure protrusions 31 are accommodated in the support ring 19 as shown in FIG. 7A, the seven acupressure protrusions 31 are accommodated in the support ring 19 as shown in FIG. 7B. Since the gap 39 is smaller than that of the case, the repulsive force between the adjacent acupressure protrusions 31 is increased, and the acupressure protrusion 31 is stabilized in posture.

(2) Action of body massage device (see FIGS. 6 and 7)

(4) Contents and results of comparative test (see Fig. 9)
Next, the content and result of the comparative test performed in order to test the effect of the body massage tool 1 of the present invention configured as described above will be described.
In this comparative test, body massager 49 provided with acupressure balls 47 as comparative example 1, body massager 51 with acupressure protrusions 31 arranged in a fixed state in a direction along the axial direction Z as comparative example 2, and comparative example 3 The three types of body massage devices 53, the body massage device 53 in the state where the acupressure protrusion 31 is removed from the body massage device 1 of the present invention and only the support ring 19 is taken up, and these three types of Comparative Examples 1 to 3 and the present invention product are taken up. The difference between the strength of magnetic force and the degree of concentration with the iron powder S was compared.

(A) Results of Comparative Example 1 (see FIG. 9 (a))
In Comparative Example 1, the acupressure point O is only one point that is a contact point between the acupressure ball 47 and a specific part of the body. In this case, the iron powder S is attached to only one acupressure point O, but the amount is extremely small.
(B) Results of Comparative Example 2 (see FIG. 9B)
In Comparative Example 2, the acupressure point O is the top of each of a plurality of acupressure protrusions 31 that are aligned and arranged in a fixed state. In this case, iron powder S is attached to one point of the acupressure point O, but the amount thereof is small as in the first comparative example.

(C) Results of Comparative Example 3 (see FIG. 9 (c))
In Comparative Example 3, the acupressure point O is the entire circumference of the distal end surface 27 of the support ring 19. In this case, iron powder S is attached to only a part of the annular acupressure point O, and the amount thereof increases.
(D) Result of the product of the present invention (see FIG. 9 (d))
In the product of the present invention, the acupressure point O is the top of each of the multiple acupressure protrusions 31 held by a magnetic force in a freely movable state. In this case, the iron powder S is uniformly applied to each point of the acupressure points O, and the amount thereof is increased.

Therefore, in the case of the comparative example 1 which uses the acupressure ball 47 and does not have the support ring 19, the strength of the magnetic force is weak and the concentration of the magnetic force is small. In the case of Comparative Example 2 including a plurality of acupressure protrusions 31 arranged in a fixed state and having no support ring 19, the result was that the strength of the magnetic force was weak and the concentration of the magnetic force was small.
Moreover, in the case of the comparative example 3 which is not provided with the acupressure protrusion 31 and has only the support ring 19, the strength of the magnetic force is increased, but the distribution is biased and the concentration of the magnetic force is small. Further, in the product of the present invention including the acupressure protrusion 31 and the support ring 19 that are held in a movable state by magnetic force, the strength of the magnetic force is increased, and the concentration degree of the magnetic force is increased so that a strong magnetic massage effect is obtained. It has been demonstrated that

For such a result, the use of a plurality of acupressure protrusions 31, the provision of the support ring 19, and the protrusion 35 of the acupressure protrusion 31 projecting from the front end surface 27 of the support ring 19. In addition to this, the fact that a plurality of acupressure protrusions 31 are held in a floating state is deeply related.
That is, in the case of the product of the present invention that satisfies such conditions, the direction of the lines of magnetic force emitted from each acupressure point O is not uniform as in Comparative Example 2, and is different for each acupressure point O. It is assumed that the concentration of magnetic force increased and a strong magnetic massage effect was obtained.

In addition, the body massage tool 1 of this invention is not limited to the thing of embodiment mentioned above, The change within the summary of the invention is possible.
For example, the number of acupressure protrusions 31 is not limited to the number described in the above embodiment, and can be appropriately changed according to the difference in the inner diameter of the support ring 19, the diameter of the acupressure protrusion 31, and the like . Further, a plurality of sets having different diameters of the acupressure protrusion 31 and the shape of the distal end portion 35 are prepared, and the optimal acupressure protrusion 31 corresponding to a difference in a specific part of the body to be applied or a difference in purpose of use is prepared. It is also possible to select and use a set. Further, the handle 9 provided in the main body casing 3 may not necessarily be provided, and the body massager 1 without the handle 9 can be provided, and the shape of the main body casing 3 is also described in the above embodiment. Not only the truncated cone shape but also various shapes can be adopted.
