Abstract

PURPOSE:To provide more effective massage on not only wide or curved skin surface but also bent regions of a human body, e.g., the elbow, knee etc., with smooth and continuous movement. CONSTITUTION:An unbalanced weight is fixedly attached to the rotation axle of a motor housed in the body of a massager to generate vibration by rotation of the motor; such vibration is conveyed to rotatively reciprocating spherical rollers (eight in number) for giving finger-pressure therapy, attached to the both ends of an axle B via a rotatively reciprocating axle A installed coaxially with the axis of the massager body and the rotatively reciprocating axle B linked perpendicularly to the axis of a rotating part A' provided at the both ends of the axle A.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massager as a health tool for massaging an arbitrary part of a human body.

[0002]

2. Description of the Related Art A conventional massager handles a vibrating section for directly vibrating an unbalanced weight directly or indirectly attached to a rotating shaft of a motor to obtain a vibration, and a case storing a motor and a power supply section. A bar-shaped massager is commonly used. In this case, the vibrating part often doubles as the acupressure part. In this general structure, the vibrating portion has a substantially cylindrical shape or an elliptical shape, or locally forms protrusions, which can be said to be suitable for one-point massage. On the other hand, it is not suitable for massaging a wide surface or a curved surface, or a bent part such as an elbow or knee, and it cannot be massed randomly.

[0003]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a means capable of more effective massage by smooth and continuous movement not only on a wide surface or a curved surface but also on a bent portion. It is to provide.

[0004]

In order to achieve the above object, the present invention provides a lower part of a vibrating section which comprises a motor having an unbalanced weight attached to a rotary shaft and a main body case accommodating a power source section for driving the motor. In addition, a plurality of acupressure balls that are pressed against the body and massaged are attached as a mechanism capable of three-dimensional displacement (three-dimensional displacement), and the acupressure balls themselves are also rotatable. In this configuration, since the shiatsu balls can be displaced three-dimensionally, the shiatsu balls can be massaged while sliding anywhere on the human body.

[0005]

The structure for three-dimensionally displacing a plurality of acupressure balls with the above configuration will be described later in the embodiment. When the handle is pressed against the upper part of the main body case described above, a plurality of acupressure balls can easily fit on the body, and if they are moved as they are, acupressure can be performed along the line of the body. When the power is turned on in this state, the vibrating section vibrates, and of course, the acupressure ball also vibrates and becomes a vibrator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, (1) is a main body case that houses a motor (2) having an unbalanced weight (4) fixed to a rotating shaft (3), a dry battery (5), a switch (6), and the like. The case lid (12) can be detachably opened and closed with a screw or the like at the one end opening of the main body case (1) so that the battery can be taken in and out. The handle (7) is the main case (1)
Is attached or anchored to. A pair of support plates (8) are formed on the front and rear sides of the body case (1) in the axial direction,
This is provided with a bearing (8a). The bearing (8a) has a fulcrum portion (9a) formed on the support shaft A (9).
However, it is fitted by means that is rotatable and does not fall off (specifically, D <d in FIG. 4). Also, each spindle A (9)
At both ends A'of the shaft, a shaft portion (9b) fitted in a bearing A'formed in the central portion of the support shaft B for rotatably supporting the support shaft B (10) and the fitting are facilitated. The notch (9c) and the bearing (10a) are formed so as to prevent the bearing (10a) from falling off. Both ends A'of the spindle A
Both end shafts (10) of each support shaft B (10) attached to the
A shiatsu ball (11) is rotatably fitted in b). The fitting means is the same as that of the bearing A '(10a), and the description is omitted. The surface of the acupressure ball (11) may be provided with dimples or protrusions for enhancing the acupressure effect. According to the above configuration, when the handle (7) is grasped and pressed to an arbitrary place on the human body, the eight acupressure balls (11) move three-dimensionally via the support shafts A (9) and B (10). It becomes easy to fit on the surface of the human body, and it is possible to perform extremely efficient acupressure massage by sliding the handle back and forth and left and right. Switch (6) in the above state
When the motor is turned on, the motor (2) to which the unbalanced weight (4) is fixed rotates at high speed, and the vibration generated thereby causes the body case (1) → spindle (9) → spindle B (10) →
It is transmitted to the acupressure ball (11), and vibration massage can be applied to the human body in addition to the above acupressure massage to remarkably increase the massage effect. Although not shown,
Structurally, a packing is fitted between the main body case (1) and the case lid (12), and switching can be performed from the outside of the case by using a combination of a reed switch and a magnet, so that it can be used in a bathroom or the like. You can also FIG. 8 shows another embodiment of the attachment structure of the acupressure ball (13). At both ends of the support shaft B (14), spherical acupressure ball receiving portions (15) each having an inner diameter slightly larger than the outer diameter of the acupressure ball are formed. The acupressure ball receiving portion (15) is slightly larger than a hemisphere, and the lower end opening (15a) has a diameter d smaller than the diameter D of the acupressure ball (13). The fitting can be done by press fitting or by utilizing expansion due to temperature difference. The acupressure ball (13) in the fitted state can freely rotate in the acupressure ball receiving portion (15). FIG. 9 shows an embodiment in which the body case itself is also used as a handle. It is needless to say that the present invention is not limited to the above embodiment and can be applied to a type that uses a commercial AC power source through a power cord.
In addition, in carrying out the present invention, the concrete structure, shape, position, material, etc. of the main body, the drive mechanism, the support shafts A and B, the acupressure balls, etc. may be configured in various modes as long as they do not violate the gist of the invention. Of course you can.

As described above in detail, according to the massager of the present invention, it is possible to move three-dimensionally by the vibration transmitted from the vibrating portion stored in the main body case and the combination of the support shafts A and B in the lower part of the main body case. It is possible to obtain a massager that fits every part of the human body surface by the interaction with the acupressure of the acupressure ball and that slides continuously and has an extremely high massage effect.
