  The conventional body massage device has the following problems. First, since the electric massager according to Patent Document 1 has a straight bar shape, it is limited to use with a hand and cannot be used on a floor surface, a seat surface of a chair, or a backrest. is there. In addition, the direction in which the steel ball protrudes and descends coincides with the axial direction of the motor, and the load applied to the steel ball at the time of striking directly acts on the output shaft of the motor in the axial direction.

Both the massage device according to Patent Literature 2 and the magnetic acupressure device according to Patent Literature 3 are L-shaped in a side view, and are mainly used for shoulder hitting. As with, there is a limit to applications.
In addition, since both adopt a structure in which the rotation direction of the driven magnet is directly switched using the rotation of the magnet on the drive side, the load applied at the time of striking acts in the bending direction with respect to the motor output shaft. It was a structure to do.

  The present invention has been made on the basis of the above points. The object of the present invention is a magnet that is small and portable, can be used in various forms of use, has a low load on the motor, and has a high massage effect. It is to provide a body massage device of the type.

  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 steel acupressure ball provided in a freely swingable state at the distal end portion of the main body casing, and a base side of the main body casing. A fixed magnet provided in a fixed state, a movable magnet provided in a spaced position opposite to the fixed magnet, and provided in a state of being reciprocally movable in the tapping direction integrally with the acupressure ball, and the fixed magnet and the movable magnet. A rotating body provided in an intermediate portion and a motor for rotating the rotating body are provided, and the movable magnet is provided in a direction in which a magnetic force is repelled with respect to a fixed magnet. A movable magnet and a magnetic material to be adsorbed are provided.

  The body massage tool according to claim 2 is characterized in that, in the body massage tool according to claim 1, the magnetic material is provided at a position retracted from the outer peripheral surface of the rotating body.

  The body massage device according to claim 3 is the body massage device according to any one of claims 1 to 2, wherein a stopper for avoiding a contact state between the movable magnet and the rotating body is provided in the body casing. It is characterized by being.

The following actions can be obtained by the above means. First of all, by adopting a main body casing that can be held directly by the user's hand or installed on a flat surface, the user can directly hold it by hand, install it on the floor, or sit on the seat. It can be used by installing it on a surface or backrest.
In addition, the use of a steel ball acupressure ball provides a smooth movement of the contact portion and a gentle massage effect on the contact portion, and blood circulation at the contact portion is promoted by the action of magnetic lines of force from the acupressure ball.

  Further, the protruding state of the acupressure balls is formed by the repulsive force of the movable magnet and the fixed magnet, and the movable range of the movable magnet is expanded by using one magnet as the fixed magnet.

Further, when the magnetic material provided in a part of the rotating body is opposed to the movable magnet, an attracting force that attracts the movable magnet is generated, and a retracted state of the acupressure ball is formed.
In addition, a force that tries to move the movable magnet and the rotating body in contact with the movable magnet to the fixed magnet side is generated by strongly pressing the pressure ball against the contact portion. Since the clearance between them is set to be extremely small, the force acting on the rotating body is absorbed by coming into contact with the fixed magnet, and the load acting on the output shaft of the motor is negligible. In addition, since the acupressure ball is in a protruding state due to the repulsive force between the movable magnet and the fixed magnet, the cushioning action works to move the movable magnet and the rotating body in contact with the movable magnet to the fixed magnet side. Therefore, the load acting on the output shaft of the motor is very small. Furthermore, since the magnetic material with the upper surface facing a part of the outer peripheral surface of the rotating body is provided, an eccentric load is not applied to the output shaft of the motor, and therefore the load acting on the output shaft of the motor is very small. Therefore, the load on the motor can be made extremely small.

  Further, when the magnetic material is provided at a position retracted from the outer peripheral surface of the rotating body, a small force is required when the movable magnet attracted to the magnetic material is pulled away from the magnetic material. Further, since the movable magnet and the magnetic material are always in a non-contact state, wear of the magnetic material is prevented.

  Also, if a stopper is provided in the main body casing to avoid the contact state between the movable magnet and the rotating body, the movable magnet is moved toward the fixed magnet side by strongly pressing the acupressure ball against the contact portion. Even if a force is generated, the generated force is absorbed by the stopper, so that the force does not act on the rotating body or the output shaft of the motor. Therefore, the life of the motor can be further increased.

  According to the body massager of the present invention, it is small and can be carried, can be used in various usage conditions, and the life of the motor can be extended with the small load on the motor, or a small motor can be adopted. To. Moreover, since the stroke of the acupressure ball protrudes and retreats, the hitting action is enhanced to increase the massage effect, and the massage effect by the magnetic lines can be obtained by adopting the steel acupressure ball.

Based on the above structure, the effect | action of the body massage tool 1 of this invention is demonstrated.
FIG. 6 is a side view showing a case where the body massage tool of the present invention is held and used by hand, and FIG. 7 is a side view showing a case where the body massage tool is used for massage of the sole in a posture installed on the floor and seated on a chair. Fig. 8 is a side view showing the case of using the back massage in the posture of being placed on the floor and lying on the floor. Fig. 9 is the same as above, and Fig. 9 is massage of the waist in the posture of being installed on the chair and sitting on the chair. It is a side view which shows the case where it uses for.
First, the case where the body massage tool 1 of the present invention is used while being held by the hand B as shown in FIG. 6 will be described.

In this case, as shown in FIG. 6, the user A grasps the body massage tool 1 so as to cover the base portion 9 with the palm, and operates the operation portion 24 of the switch 23 with a finger to rotate the motor 17.
The user A massages a rigid part of the body by pressing the acupressure ball 7 on the part to be massaged and sliding the body massage tool 1 appropriately along the contact part.

The rotation of the output shaft 45 of the motor 17 is transmitted to the rotator 15, and the rotator 15 rotates at a predetermined rotational speed. Then, when the magnetic material 51 having the upper surface 53 facing a part of the outer peripheral surface of the rotating body 15 faces the lower surface 35 of the movable magnet 13, the movable magnet 13 is attracted to the magnetic material 51, and the retracted state shown in FIG. In other positional relations, the movable magnet 13 is projected due to the repulsion of the magnetic force between the fixed magnet 11 and the movable magnet 13.
Thereafter, by repeating the above action, a hitting action by the acupressure ball 7 pressed against the contact portion of the user A is executed, and a desired massage effect is obtained by adding a magnetic line effect of the acupressure ball 7 itself. Become.

Further, since the acupressure ball 7 is provided in the idle state, the abutment portion against the body can be moved in the sliding direction while performing the tapping action by appropriately rotating the acupressure ball 7. ing.
In addition, when the acupressure ball 7 is strongly pressed against the contact portion, a force for moving the movable magnet 13 toward the fixed magnet 11 acts on the movable magnet 13, but is positioned between the movable magnet 13 and the fixed magnet 11. The presence of the rotating body 15 prevents the output shaft 45 of the motor 17 from being subjected to a load that hinders operation. Further, since the acupressure ball 7 is in a protruding state by the repulsive force between the movable magnet 13 and the fixed magnet 11, the cushioning action works to fix the movable magnet 13 and the rotating body 15 that contacts the movable magnet 13. Since the force to be moved to the magnet 11 side is absorbed, the load acting on the output shaft 45 of the motor 17 is very small. Further, since the magnetic material 51 having the upper surface facing a part of the outer peripheral surface of the rotating body 15 is provided, an eccentric load is not applied to the output shaft 45 of the motor 17, and thus a load acting on the output shaft 45 of the motor 17.

At this time, since the cushion material 27 is provided on the lower surface of the base 9, slipping on the floor surface of the body massage device 1 is prevented. Further, the impact applied to the sole of the foot is relieved by the cushioning action of the cushion material 27.

  Moreover, when the body massage tool 1 is installed in the plane part C on the upper surface of the floor as shown in FIG. 8 and the user A is sleeping while looking up, the body massage is performed as shown in FIG. When the device 1 is installed in the lower part of the back of the chair E and the user A massages the waist in a posture seated on the chair E, in addition to the same action as described above, acupressure by the weight of the upper body of the user A The effect is added and a more effective massage is performed.

In addition, the body massage tool 1 of this invention is not limited to said form, The change within the summary of the invention is possible. For example, the shape of the main body casing 3 is not limited to that of the illustrated embodiment, and various shapes such as those having a handle and an operating rod can be employed.
The acupressure balls 7 are all made of steel, and may be a composite material, an alloy, or the like, part of which is made of other materials within a range in which the same action is exhibited.

Further, the shapes of the fixed magnet 11 and the movable magnet 13 are not limited to the short cylindrical shape, and various shapes such as a short rectangular block shape can be adopted. Further, a stopper 59 or the like for avoiding the contact state between the movable magnet 13 and the rotating body 15 can be provided in the main body casing 3 as shown in FIG. Incidentally, when the stopper 59 as described above is provided, the movable magnet 13 does not contact the outer peripheral surface of the rotating body 15, so the position of the upper surface 53 of the magnetic material 51 is the same as the outer peripheral surface of the rotating body 15. It becomes possible to set the level.
Even when the body massage tool 1A shown in FIG. 10 is used, the same actions and effects as those of the body massage tool 1 shown in FIGS.
