The vibrator mechanism used in the “chair type massage machine with built-in vibrator with armrest” disclosed in Japanese Patent Application Laid-Open No. 2003-70859 has a fan-shaped rotating weight fixed to the rotating shaft of the motor , and the rotating weight has a diameter of the motor . There is a problem that it is smaller than that and cannot generate a very strong vibration.

On the other hand, the “vibrator device and portable terminal device” disclosed in Japanese Patent Application Laid-Open No. 2011-56455 has the same configuration and problems as described above, but this is intended to generate a vibration for notifying an incoming call to the portable terminal device. This kind of vibrator device, which does not originally require such a strong vibration and cannot generate a very strong vibration, is sufficient. The first rotating body and the second rotating body of the vibrator device are also characterized by being smaller than the diameter of the motor .

  However, the present inventor wanted to provide a massage tool that can generate strong vibrations and effectively vibrate the body.

  Prior to solving this problem, the present inventor has realized that the diameter of the weight to be rotated should not be made smaller than the diameter of the motor as in the prior art, but should be made larger. As a result, it has been found that a greater vibration can be obtained, but it has been found that there is a drawback that it is difficult to hold when this mechanism is used for a handy type massage device. For example, if the handle is provided on the vibration generating part of this mechanism, the vibration generating part swings greatly, and the hand holding the handle is not stable. That is, unless the hand with the handle is stable, even if a large vibration is generated, it is not transmitted effectively to the body, and a sufficient massage effect cannot be achieved. The inventor was then forced to solve such a problem.

The above-mentioned problem is a massage device having an electric motor and a weight attached to the shaft of the electric motor so that the center of gravity is located at a position eccentric from the rotation center of the shaft in a dome-shaped housing. The weight is composed of a revolving part that faces the outer peripheral wall of the electric motor and a bridging part for attaching the revolving part to the shaft of the electric motor, so that the entire casing can be wrapped with a palm. This is achieved by providing a concave portion that has a substantially hemispherical shape and is easy to catch a finger when wrapped with a palm. Note that the power switch unit and the vibration control unit of the electric motor may be provided in the case, or a remote controller is attached separately from the case and the power switch unit and the vibration control unit of the electric motor are provided. May be. In addition, a dry battery may be used for the power supply unit, but a household power supply or a secondary battery that is charged from here may be used.

The feature of the vibration generating portion of the present invention is that the weight is eccentrically attached to the shaft of the electric motor, but the weight portion is provided at a position where it can circulate facing the outer peripheral wall of the electric motor. Therefore, the weight does not rotate in the vicinity of the shaft as in the prior art, but rotates so as to grind the outer peripheral wall of the electric motor. According to the dictionary, “grind” refers to turning with a pattern such as “light”, but such rotation of the image.

  On the other hand, instead of providing a handle on the vibration generating part that performs such a large vibration, the entire housing of this massager is made into a substantially hemispherical shape that can be wrapped with a palm (the meaning of a substantially hemispherical shape is (It will be described in Example 1), and a recess is formed so that a finger can be easily caught when wrapped with a palm. Therefore, just like grasping a heel, grasping the case so as to wrap it with a palm and pressing it against a desired part of the body. By gripping like this, it is possible to grip the case firmly and not only shake the case but also add vibration energy to the body so that it does not shake, increasing the massage effect sufficiently To get.

By the way, it is good to comprise such an excellent massage tool so that the shape of the side which presses against the body of the said housing | casing may exhibit the shape which spreads outward like a suction cup . The part pressed against the body may be substantially flat and the entire surface may be in contact with the body (although this part can be convex or uneven), it is not so. If it is shaped like a sucker and its surroundings come into contact with the body (although it can be said that the mouth on the side that is open like a morning glory flower is in contact with the body) It was found that this produces an effective action.

  That is, when the periphery of the open shape comes into contact with the body, it can be seen that the skin swells and enters the open shape in the middle part. Then, since this acts in the direction which suppresses the shake of a housing | casing, the massage effect increases more. Depending on the material of the open-shaped part, there may be a suction action like a suction cup.

  Now, in the massage device as described above, the recess may be formed in at least a part of the periphery of the housing. This is a configuration for gripping the casing firmly so that the base of the thumb and the tip of the finger can enter when the casing is grasped so as to be wrapped with a palm and pressed against a desired part of the body.

  Or the said recessed part is good also as what is formed over the perimeter of the said housing | casing. With this configuration, when grasping and grasping the casing so as to be wrapped with a palm, a better grip feeling can be obtained no matter how it is grasped without worrying about the position of the recess.

Further, in the massage device as described above, at least the concave portion of the casing may be made of a material that is difficult to slip, or may be formed with non-slip unevenness . For example, if the concave portion, other portions including the concave portion, or almost the whole is made of a material that is difficult to slip, there is less concern that the casing is firmly wrapped with a palm and displaced. Or it becomes difficult to slip even if it is held with wet hands. Silicone resin is used as an example of a material that is difficult to slip. Moreover, even if it is a housing | casing used as a general synthetic resin material, it is possible to make it hard to slip | slip by forming a non-slip | skid unevenness | corrugation by mat | matte processing or embossing, for example. This area can be devised freely.

  According to the massage device of the present invention, it is possible to effectively vibrate the body by generating strong vibrations, and the case is shaken when the case is gripped so as to be wrapped with a palm and pressed against a desired part of the body. It is possible to apply vibration energy to the body as much as possible, and the intended purpose of achieving a sufficient massage effect has been achieved.

  It is explanatory drawing by the side view of Example 1. FIG.   It is explanatory drawing by a bottom view.   It is explanatory drawing of the electric motor 2 which has the eccentric weight 3. FIG.   It is explanatory drawing by the oblique view of Example 1. FIG.   It is explanatory drawing which represented the electric motor 2 periphery with the block diagram.   FIG. 6 is an explanatory diagram of a controller 5 according to Embodiment 2.   It is explanatory drawing by the side view of Example 3. FIG.   It is explanatory drawing by the bottom view of Example 4. FIG.

The massage tool of this embodiment will be described with reference to FIGS. The housing 1 in which the opening 13 is formed in a shape that spreads outward, such as a suction cup , on the lower side of the side that is in contact with the body, on a part of the side 11 above the opening 13, A recess 12 is formed so that a finger can be easily applied. Above the side portion 11 is a top portion 10 like a hat. Therefore, when the casing 1 is wrapped from the top 10 with the palm, the belly of the finger comes into contact with the side portion 11, but a part of the finger hangs into the recess 12, so that the palm and the fingertip are firmly attached. The housing 1 can be gripped. When the housing 1 is gripped by hand in this way, the side of the opening 13 having a shape that is substantially sucker-shaped becomes the side that contacts the body.

The casing 1 is formed in a hollow dome shape of a synthetic resin material, and although the opening 13 is characteristic, it can be said that the whole is substantially hemispherical. An electric motor 2 having a weight 3, which is a vibration generating portion, is housed and attached in a motor case 22. As shown in FIG. 3, the weight 3 includes a rotating portion 31 that rotates around the outer peripheral wall 21 of the electric motor 2 and a bridging portion 30 for attaching the rotating portion 31 to the shaft of the electric motor 2. ing. Although both the bridging portion 30 and the rotating portion 31 are weights, the weight 3 does not simply rotate in the vicinity of the shaft 20 as in the prior art. Since the heavy bridging portion 30 and the rotating portion 31 rotate, particularly the rotating portion 31 rotates outside the outer peripheral wall 21 of the electric motor 2, and the weight 3 as a whole rotates to grind as described above. A big vibration is obtained with a feeling of weight.

Therefore, as represented in Figure 4, grip but not can be securely grip the housing 1 when the grip so as to wrap the housing 1 in the palm, which was nicely more conveniently when exposed to finger in the recess 12 Is obtained. When the weight 3 is grinded, it can vibrate effectively by giving strong vibrations to the body. However, when the casing 1 is pressed against a desired part of the body by holding as described above. In addition, it has been an extremely great achievement that the energy of vibration that the case 1 does not shake can be applied to the body.

  The electric motor 2 is schematically shown in the block diagram of FIG. 5, but is connected to the motor control unit 4, and the motor control unit 4 is connected to an external power adapter 40. Although the motor control unit 4 is not illustrated in FIG. 1, the electric power from the household power source is converted into direct current by the power adapter 40 and then applied to the electric motor 2. The motor control unit 4 is responsible for rotation control such as the strength of rotation of the electric motor 2. The power switch and control switch are not shown. Further, a secondary battery for charging may be provided. Alternatively, without using the power adapter 40, that is, the power for driving the electric motor 2 is not taken from the household power supply, a dry battery may be provided in the housing 1.

  FIG. 6 shows the controller 5 of this embodiment. In the first embodiment described above, the motor control unit 4 is provided in the housing 1, but in the second embodiment, this is moved to the controller 5 side.

  That is, the controller 5 includes an electric wire 55 for connecting to the main body of the massage tool and an electric wire 56 for connecting to the outlet, and a power plug (not shown) is provided at the tip of the electric wire 56. Reference numeral 50 denotes a power button. The power button 50 is a toggle type that is turned on when pressed once and turned off when pressed a second time. When turned on, the LED power light 53 is turned on. An LED indicator 54 is provided between the up button 52 and the down button 51 to indicate the level of vibration intensity. The vibration is designed to become stronger each time the up button 52 is pressed and to be weaker every time the down button 51 is pressed. That is, the controller 5 includes a motor control unit that performs such various controls. In this embodiment, membrane switches are used for the power button 50, the down button 51, and the up button 52. The power button 50 is a power ON / OFF toggle type, but a function for switching rhythm vibration may be added thereto. Then, the down button 51 and the up button 52 can be operated for each type of rhythm vibration. Note that random vibration may be incorporated into the configuration.

The massage tool of this embodiment will be described with reference to FIG. The casing 6 has an opening 64 formed in a shape that spreads outward, such as a suction cup , on the lower side, which is the side in contact with the body, and below the side portion 61 above the opening 64. On the side, a recess 62 is formed over the entire circumference so that a finger can be easily applied. Above the side portion 61 is a top portion 60 like a hat. The surface of the recess 62 is rough matted to form a matte portion 63 to prevent slippage. In addition to matting, slipping can also be prevented by applying a rubber band to the recess 62.
