Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handheld massage machine.

[0002]

2. Description of the Related Art Conventionally, home-use massagers have a placement type in which a massage body such as a massaging ball is provided on the upper surface of a housing placed on a floor or the like, and a massage body is provided on a side surface of a casing having a hand-held portion. Hand-held type. Of these, a handheld massager generally employs a vibrator that vibrates at high speed as the massaging body.However, a pair of kneading balls are provided on the side surface of the end of the casing, and these kneading balls are connected. There is also one in which a rocking means for rocking in the separating direction is provided in the casing.

[0003]

By the way, the above-mentioned kneading balls have a function of strongly and slowly rubbing the affected area, and the vibrator has a function of giving high vibration to the affected area to unravel. However, none of the conventional hand-held massagers can simultaneously perform the rubbing action and the vibration action. Therefore,
It is conceivable to provide a vibrating means for vibrating the kneading balls inside the kneading balls to construct a hand-held massage machine having both functions.

However, if vibration is simply applied to the massaging balls, vibration force will be applied to the massaging balls which originally have a strong pressing force, and therefore, when the massaging balls are used by pinching the neck or legs, an excessive pressing force is applied. Pressure may be applied to the affected area, which may rather hurt the affected area. Also, when the vibrating means is provided in the kneading balls, the vibration from the vibrating means is transmitted to the casing,
There is a risk of damaging the gear mechanism that constitutes the swinging means and the electrical wiring inside the casing at an early stage.

In view of such circumstances, it is an object of the present invention to provide a handheld massager that can safely perform an appropriate and comfortable massage according to the condition of the affected area without impairing the durability of the massager itself. .

[0006]

[Means for Solving the Problems] In order to achieve the above object,
Technical means taken by the present invention is a hand-held massager in which a pair of kneading balls are projectingly provided on a side surface of a casing having a hand-held portion, and rocking means for rocking the kneading balls in a contacting / separating direction is provided in the casing. In the machine, a vibrating means for vibrating the kneading balls is provided in the kneading balls, and the kneading balls and the swinging means are connected by elastically deformable spring members in the contacting and separating directions of the kneading balls.

[0007]

The vibrating means provided in the kneading balls vibrate the kneading balls, and in addition to the kneading action by the rocking of the kneading balls, the massage effect by the vibration action is added. When the affected part is sandwiched between a pair of kneading balls, the spring member is elastically deformed in the contacting / separating direction of the kneading balls to prevent an excessive pressing force from the kneading balls to act on the affected part. Further, the spring member suppresses the vibration of the vibrating means from being transmitted to the swinging means.
