JP 2003-70859 A JP 2011-56455 A

  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 rotary weight 23 fixed to a rotary shaft 19A of a motor 19, Has a problem that it is smaller than the diameter of the motor 19 and cannot generate 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 20 and the second rotating body 30 of the vibrator device 10 are also characterized by being smaller than the diameter of the motor 11.

  However, the present inventor wanted to provide a massage device that can generate a strong vibration to effectively vibrate the body.

  Prior to solving this problem, the inventor has realized that the diameter of the weight to be rotated is not made smaller than the diameter of the motor as in the prior art, but may 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 these problems.

  The subject is a massage device including an electric motor and a weight attached to the shaft of the electric motor in an eccentric state, wherein the weight circulates around an outer peripheral portion of the electric motor extending from the shaft. The entire body of the massage device has a substantially hemispherical shape that can be wrapped with a palm, and a recess is formed in the housing that makes it easy for a finger to hang when wrapped with a palm. In addition, this is achieved by providing a massage tool having a shape in which the side that comes into contact with the body when the entire casing is wrapped with a palm opens in a substantially sucker shape. 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 part of this device is that the weight is eccentrically attached to the shaft of the electric motor, but the weight portion is extended to a position where it can go around the outside of the electric motor. Therefore, the weight does not rotate in the vicinity of the shaft as in the prior art, but rotates to grind the outside 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, and at this time, the thumb ball (the bulge of the base of the thumb) and the fingertip enter the recess. 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.

  Furthermore, it is preferable that the side that comes into contact with the body when the entire casing is wrapped with a palm exhibits a shape that is opened in a substantially sucker shape. The part to be pressed against the body may be substantially flat and the entire surface may be in contact with the body, but instead, it is shaped like a sucker and its surroundings are in contact with the body (substantially It has been found that the funnel-like open mouth like a morning glory flower makes contact with the body), but has another effective effect. 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 into 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.

  In the massage device as described above, at least the concave portion of the housing may be provided with a slip stopper. 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 will be wrapped with a palm and 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, for example by giving a matt process or embossing. This area can be devised freely.

  According to the massage device of this device, it can vibrate the body effectively by generating strong vibrations, and it touches the body when grasping the case so that it is wrapped in the palm and pressing it against the desired part of the body Helping with the action of making the side to be opened in a generally sucker shape, it is possible to add vibration energy to the body as much as it does not shake, and it will increase the massage effect sufficiently The intended purpose 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 a second embodiment.   It is explanatory drawing by the side view of Example 3. FIG.

  The massage tool of this embodiment will be described with reference to FIGS. The housing 1 in which the opening 13 is formed on the lower side, which is the side to be brought into contact with the body, in a shape that is opened in a substantially sucker shape, has a finger placed on a part of the side 11 above the opening 13. A recess 12 is formed so as to be easily hooked. 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 of a synthetic resin material in a hollow shape, and although the opening 13 is characteristic, it can be said that the entire case 1 has a substantially hemispherical shape. 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 portion 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 portion 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 shown in FIG. 4, if the housing 1 is gripped so as to be wrapped with a palm, the housing 1 can be firmly gripped. 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 housing 6 is formed with an opening 64 in a shape that is open in a substantially sucker shape on the lower side, which is the side that comes into contact with the body, and on the lower side of the side portion 61 above the opening 64. 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.

  The casing 6 is formed of a stainless steel hollow shape, and an electric motor 2 having a weight 3 as a vibration generating portion is attached inside. The weight 3 is the same as that shown in FIG.

  In addition, it is preferable to devise such as imparting waterproofness to the massage device of this device. More convenient for use in bathrooms. In order to further enhance the grip feeling, a band to be passed to the back of the hand may be provided. In addition, an illumination light that illuminates the top, bottom, and the whole of the housing is sufficient to make it entertaining.

  The use of the massage device of this invention is wide-ranging and can be configured for medical use, pet use, and the like.
