Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a massage machine that massages the soles and shoulders of a foot with a vibrating diaphragm.

[0002]

[Prior Art]

 Various types of massage machines have been conventionally known for performing massage with a vibrating diaphragm. For example, as disclosed in Japanese Patent Laid-Open No. 3-75061, the center of gravity of the vibrating plate and the center of gravity of the counterweight are known. It is proposed that the components are arranged on the same plane perpendicular to the rotation axis, the diaphragm vibrates smoothly, the main body is stable without dancing, and the noise is low.

[0003]

[Problems to be solved by the device]

 However, in such a conventional one, the main body is stable, the noise is small, and the vibrating diaphragm provides a suitable massage, but the effect is not more than the massaging effect by the vibrating plate.

Therefore, the present invention has an object to solve the above-mentioned problems and provides a massager in which other effects are added in addition to the massage effect by the diaphragm.

[0005]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention has the following configuration as means for solving the problems. That is, a diaphragm oscillated by the rotational movement of the crank shaft that is interlocked with the motor, and a center of gravity that is interlocked with the crank shaft and is located on the opposite side of the center of rotation of the crank shaft from the center of gravity of the diaphragm. A massaging machine having a counterweight for canceling the reaction of the swing, wherein the diaphragm is made of a non-magnetic material, the counterweight includes at least a magnet, and the center of gravity of the diaphragm and the counterweight The center of gravity and the center of gravity are arranged on the same plane perpendicular to the crankshaft, and the magnet is arranged at a position where the magnet passes behind the diaphragm, which is the configuration of the massage machine.

[0006]

[Action]

 In the massage machine having the above structure, the diaphragm vibrates when the crank shaft that is linked to the motor rotates. Then, the counter weight interlocked with the crankshaft balances the force vertically applied to the crankshaft due to the oscillation of the diaphragm, and cancels the reaction in the oscillation direction. Furthermore, since the center of gravity of the counterweight and the center of gravity of the diaphragm are arranged on the same plane perpendicular to the crankshaft, the points of action of the force exerted by the diaphragm and the counterweight perpendicular to the crankshaft are both Since they are located on the same plane, no force that causes blurring in the crankshaft direction is generated. Therefore, the diaphragm is stable and swings, and the entire device is stable.

Further, since the magnet passes through the back side of the diaphragm, the magnetic force of the magnet acts on the sole of the foot placed on the diaphragm to promote blood circulation, metabolism, and fatigue. To recover.

Moreover, although the center of gravity 3a of the diaphragm 3 is lowered to the case 1 side by this, the inclined surface 3c is not limited to one side of the rectangular shape and is provided on two or more sides, or a separate weight is fixed. The center of gravity 3a may be lowered.

A large number of small projections 4 are provided on one surface of the inclined surface 3c and the flat surface 6 of the diaphragm 3, and small protrusions 4 are formed on the ridge line 3b formed by the flat surface 6 and the inclined surface 3c. A relatively large convex portion 8 is formed on the protrusion 4. The vibrating plate 3 and the case main body 1a are connected to each other by an elastic support column 10 made of rubber or the like and formed into a cylindrical shape. Four elastic columns 10 are erected from the case body 1a near each corner of the diaphragm 3, and both ends of the elastic column 10 are fixed to the diaphragm 3 and the case body 1a, respectively. It is configured to be able to swing inside.

A motor 12 is built in the case 1 so that its output shaft 14 projects toward the diaphragm 3. The output shaft 14 is rotatably supported by a bearing 16, and its output is A male screw 18 is formed at the tip of the shaft 14. The male screw 18 is screwed into the female screw 22 of the crankshaft 20 so that the output shaft 14 and the crankshaft 20 are integrated. As shown in FIG. 3, the crankshaft 20 has a prismatic boss 24 formed on the output shaft 14 side, and a flange portion 26 is formed in contact with the boss 24. Further, a cylindrical main body portion 28 is formed so as to be connected to the collar portion 26, and the center of the main body portion 28 is formed eccentric to the center of the female screw 22 by a predetermined amount.

The body 28 is attached to the diaphragm 3 via the crank bearing 30 and the mounting member 32, so that the body 28 and the diaphragm 3 can rotate relative to each other. Has been Further, in this embodiment, the crank bearing 30 is arranged so that its center point coincides with the center of gravity 3 a of the diaphragm 3.

Further, a cooling fan 34 is attached to the crankshaft 20. The cooling fan 34 has a substantially disk shape, and a substantially square hole-shaped opening 36 corresponding to the shape of the boss 24 of the crankshaft 20 is formed at the substantially center thereof. The opening 36 is fitted in the boss 24, and is sandwiched by the flange 26 and the sleeve 37 so that the cooling fan 34 rotates together with the crankshaft 20. In addition, in the present embodiment, the center of gravity of the cooling fan 34 is configured to coincide with the center of the output shaft 14.

In the cooling fan 34, a plurality of rectangular blade portions 38 are radially provided on the motor 12 side in a radial manner, and the motor 12 is air-cooled by rotation. On the other hand, two bosses 39 are erected on the diaphragm 3 side, and the counter weight 42 is fixed to the cooling fan 34.

In the present embodiment, the counterweight 42 includes a magnet 46 and a mounting plate 48, and the mounting plate 48 has a substantially hollow center, and the magnet 46 is fixed thereto by an adhesive. A screw 44 penetrating the mounting plate 48 is screwed into the boss 39 to fix the counterweight 42.

Moreover, as shown in FIGS. 5 and 6, the center of gravity 42 a of the entire counterweight 42 including the magnet 46 and the mounting plate 48 is perpendicular to the crankshaft 20 together with the center of gravity 3 a of the diaphragm 3. It is arranged so as to be on the same plane A. As shown in FIG. 5, when viewed from the axial direction of the output shaft 14 of the motor 12, the straight line B passing through the center of gravity 3 a of the diaphragm 3 and the center of gravity 42 a of the counterweight 42 and the center line 14 c of the output shaft 14 are shown. And the intersection 14a is located between the two centers of gravity 3a and 42a.

Further, as shown in FIG. 6, when viewed from a direction perpendicular to the output shaft 14, the center of gravity 3 a of the diaphragm 3 and the center of gravity 42 a of the counterweight 42 are perpendicular to the crankshaft 20. It is arranged so as to be located on the plane A. Next, the operation of the massage machine of this embodiment will be described.

When the motor 12 is started by turning on the switch 50, the output shaft 14 rotates, and the crankshaft 20 rotates together with the output shaft 14 around the output shaft 14. The center of the main body 28 of the crank shaft 20 revolves around the center of the output shaft 14. Therefore, the diaphragm 3 swings around the output shaft 14 via the crank bearing 30 and the mounting member 32 while being supported by the elastic column 10.

Further, together with the crankshaft 20, the cooling fan 34 also rotates around the output shaft 14. The motor 12 is air-cooled by the rotation of the cooling fan 34, and the counter weight 42 turns around the output shaft 14. At this time, as shown in FIGS. 5 and 6, the force 3F applied vertically to the output shaft 14 by the swing of the diaphragm 3 and the force 42F applied vertically to the output shaft 14 by the counterweight 42 are opposite to each other. It is a direction and works to cancel each other out. Therefore, the counterweight 42 cancels the reaction of the diaphragm 3 in the swinging direction.

Further, since the center of gravity 3a of the diaphragm 3 and the center of gravity 42a of the counterweight 42 are arranged on the same plane A perpendicular to the output shaft 14, the diaphragm 3 is swung when the diaphragm 3 is swung. The action point of the force 3F by the force of the counterweight 42 and the action point of the force 42F by the counterweight 42 have the same axial height of the output shaft 14.

Therefore, the counterweight 42 is arranged at the position of the conventional center of gravity 42b that is not on the plane A, and the deviation in the direction of the output shaft 14 that occurs because the action point of the force 3F does not coincide with the action point of the force 42H. The causative force does not occur in this embodiment. Therefore, the diaphragm 3 is stably swung, and the entire apparatus is stabilized.

Further, the magnet 40 of the counterweight 42 that revolves around the output shaft 14 passes below the convex portion 8 and draws a ring-shaped locus. At this time, the magnet 40 turns while applying a magnetic force to the surroundings, and forms a rotating magnetic field according to the number of rotations. Then, when the diaphragm 3 swings in this way, the massage effect can be obtained by applying the diaphragm 3 to any part of the body. Further, at this time, the flat surface 6 of the vibrating plate 3 provided with the inclined surface 3c fits well on curved parts such as feet, back and waist, and the small projections 4 and the convex parts 8 suitably stimulate those parts. . Moreover, it becomes more effective when the convex portion 8 is located on the ridge line 3b.

Further, the magnetic force of the rotating magnet 40 acts on the acupuncture points of the sole of the foot placed on the convex portion 8 to promote blood circulation and metabolism, and recover fatigue. Thus, not only the massage by the diaphragm 3 but also the recovery of fatigue can be achieved by the action of the magnetic force of the magnet 40. Moreover, since the magnet 40 also serves as the counter weight 42, the structure does not become complicated by providing the magnet 40.

In this embodiment, the center of gravity 3a of the diaphragm 3 and the center of the crank bearing 30 are aligned on the plane A, so that the force applied to the bearing balls when the diaphragm 3 swings is on the plane A. Works with. Therefore, the diaphragm 3 does not twist due to the inertial force, and the diaphragm 3 swings stably, which is also advantageous in terms of durability of the bearing balls. Further, the present embodiment is provided with one counter weight 42, but the number is not limited to one, and a plurality of counter weights 42 may be provided. In that case, the counter weight 42 may be arranged so that the resultant force matches the force 42F shown in FIGS.

In use, the feet 52 shown in FIG. 2 may be used to raise the height. The foot 52 may be attached when used, or may be stored on the side of the case body 1a when not used. The present invention is not limited to such an embodiment as described above, and can be implemented in various modes without departing from the scope of the present invention.

[Effect of the device]

 As described in detail above, in the massage machine of the present invention, not only the massage effect can be obtained by applying the convex portion of the vibrating diaphragm to any part of the body, but also the magnetic force of the rotating magnet changes the rotation speed. A rotating magnetic field is generated in response to the action of the force applied to the acupuncture points of the sole of the foot placed on the diaphragm, promoting blood circulation and metabolism, and recovering fatigue. However, since the magnet also serves as a counter weight, the structure that the magnet is provided does not complicate the structure.
