Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage machine capable of pressing and hitting.

[0002]

2. Description of the Related Art Conventionally, there is a massage machine in which a massage member is operated by an air cell which expands and contracts by air supply and exhaust. For example, Japanese Patent Application Laid-Open No. 9-327492
No. reference.

[0003]

However, a massage machine that operates a massage member by an air cell is suitable for performing a pressing operation such as massaging, but because of the nature of the air cell, a so-called tapping operation is performed. Was not always optimal. In other words, to perform the beating operation,
The massaging member must be moved quickly, such as vibration, but an air cell that expands and contracts due to air supply and exhaust is not suitable for such movement. Therefore, it was difficult to perform an effective tap.

[0004] The present invention has been made in view of such a problem, and an object of the present invention is to provide a massage machine that can perform effective tapping even in a massage machine that performs a pressing operation with an air cell. I do.

[0005]

The present invention takes the following technical means to achieve the above object. That is, the massage machine of the present invention includes an air cell that expands and contracts by air supply and exhaust, a massage member that performs a pressing operation by expansion and contraction of the air cell, and a beating driving unit that performs a beating operation on the massage member separately from the operation by the air cell. And

[0006] By providing a separate tapping drive unit in the massage machine in which the massage member operates by the air cell, in addition to the effective pressing by the air cell,
Effective hitting by the hitting drive unit can be performed. As a specific configuration of the hitting drive unit, the hitting drive unit can include a driving motor and a hitting shaft that is driven to rotate by the driving motor. Further, the hitting shaft includes an air cell base provided with a cam eccentrically fixed and oscillated by rotation of the cam, and the air cell may be provided on the air cell base. .

[0007] In this case, the rotation of the cam causes the air cell base to vibrate, and the vibration of the air cell base is transmitted to the massage member via the air cell to perform a hitting operation.
Further, since the vibration of the tapping is transmitted to the massage member via the air cell, soft tapping is performed by the cushioning action of the air cell. Further, as another specific configuration of the hitting drive unit, a swing member that swings by expansion and contraction of the air cell, and a rotation shaft rotatably supported by the swing member, the massage member is provided. The hit driving unit may be provided with a drive motor that is eccentric to the rotation shaft and that drives the rotation shaft to rotate.

In this case, the rotating shaft is rotated by the drive motor, and the massage member provided eccentrically to the rotating shaft performs a hitting operation. Since the tapping is performed by the eccentric rotation of the massage member, the cushioning action by the air cell is small, and the hard tapping is performed. in this way,
When hitting is performed by rotating a rotating shaft provided on the massage member, the beating drive unit rotates the beating shaft driven by the drive motor and the rotation of the beating shaft to the rotating shaft. It is preferable that a transmission means for transmitting the power is provided, and the swing member is provided so as to be swingable with respect to the hitting shaft.

In this case, since the hitting shaft also serves as the swinging shaft of the swinging member, even if the position of the massage member is changed by the swinging of the swinging member, the massaging member is moved from the swinging shaft. Since the distance to the rotation axis is constant, a simple transmission means can be employed.
Further, since the hitting shaft also serves as the swinging shaft, the number of components can be reduced, and the cost can be reduced.

Further, in the present invention, it is preferable that the massage member is constituted by a pair of left and right massage heads, and each massage head is configured to be capable of individually pressing and hitting. In this case, the variety of massage operations is expanded.
