Utility Model Registration No. 321609

In hand massage including fingers, a massage pressure (pressing pressure) suitable for each of the palm, the back of the hand, and the fingers is required. For example, it is known that the massage pressure suitable for the palm is higher than the massage pressure suitable for the back of the hand. However, in the massager of Patent Document 1, since the palm, the back of the hand, and the fingers are pressed by the expansion of the airbag, it is difficult to obtain the massage pressure suitable for each part.

An object of the present invention is to provide a massager capable of massaging a hand including a user's fingers with massage pressures suitable for the back of the hand, the palm, and the fingers.

One aspect of the present invention defines an insertion space into which a hand including fingers is inserted, a first main wall portion facing the back of the hand inserted into the insertion space, and the insertion space inserted into the insertion space. A housing including a second main wall portion facing the palm of the hand, an airbag for the back side of the hand for pressing the back of the hand arranged on the first main wall portion, and fingers other than the thumb of the hand are pressed. A tubular air bag for other fingers that surrounds each of the fingers, and an air bag for the back side of the hand and the air bag for the other fingers that are built in the housing and are fluidly connected to the back of the hand. An air supply source that supplies air to the back of the hand and the other finger air bag so that the side air bag and the other finger air bag expand and contract, and the second main wall portion are arranged. Provided is a hand massager including a kneading member and a drive mechanism built in the housing to move the kneading member.

The back of the hand is pressed by the expansion of the airbag for the back side, while the palm is pressed by the kneading member, so that a massage pressure higher than that of the back of the hand acts on the palm. The fingers are pressed by the expansion of the other finger airbags. As a result, the hands including the user's fingers can be massaged with massage pressures suitable for the back of the hand, the palm, and the fingers.

By inserting a finger other than the thumb into the other finger airbag, the left-right position of the palm is arranged at an appropriate position with respect to the back-side airbag and the kneading member. Thereby, the massage effect on the back of the hand and the palm can be enhanced.

The drive mechanism is characterized in that the kneading member is reciprocated in an arc shape along the wrist-side edge of the palm.

According to this configuration, the kneading member reciprocates in an arc shape along the edge of the palm, so that a portion having a high massage effect can be effectively massaged. It is easy to get the feeling of being massaged by human hands.

Preferably, an airbag for the right thumb for pressing the right thumb and an airbag for the left thumb for pressing the left thumb are further provided.

For example, when massaging the thumb, in a conventional massager without a thumb airbag, it is necessary to insert the thumb into another finger airbag to massage the thumb. On the other hand, according to this configuration, since the thumb airbag is provided in addition to the other finger airbags, all five fingers including the thumb can be massaged without replacing the fingers.

In addition, by inserting the thumb into the thumb airbag, excessive insertion of the finger is suppressed. As a result, the back of the hand and the palm of the hand are arranged at positions in the front-rear direction suitable for massage with respect to the back of the hand airbag and the kneading member. As a result, the massage effect on the back of the hand and the palm can be enhanced.

Further, preferably, an air supply means capable of supplying air to the parent finger airbag, the other finger airbag, and the instep airbag from the air supply source independently of each other. Be prepared.

According to this configuration, the airbag for both fingers, the airbag for other fingers, and the airbag for the instep can be operated independently, so that the massage operation can be diversified. The massage effect on the hands including the fingers can be further enhanced.

Further, preferably, the back side air bag has a back side wrist air bag for pressing the wrist of the hand from the back side of the hand, and the hand is more than a kneading member of the second main wall portion. The wrist side portion may further be provided with a palm side wrist air bag arranged so as to face the back side wrist air bag for pressing the wrist of the hand from the palm side.

According to this configuration, the wrist is sandwiched from the instep side and the palm side by the instep side wrist airbag and the palm side wrist airbag. As a result, the inserted wrist can hold the hand in an appropriate position with respect to the kneading member and each airbag, and the massage effect can be further enhanced.

Further, preferably, an airbag for the base of the palm side finger is further provided, which is arranged at a portion on the finger side of the kneading member of the second main wall portion to press the base of the finger from the palm side. You may.

According to this configuration, since the base of the finger on the palm side can be pressed, the massage operation can be diversified.

Further, preferably, the back-side airbag is arranged so as to face the base-side airbag of the palm-side finger, and the back-side finger base air for pressing the base of the finger from the back-side of the hand. It may be equipped with a bag.

According to this configuration, the base of the finger can be massaged by the airbag for the base of the palm side finger and the airbag for the base of the instep side finger. The groin airbags hold the groin from the back and flat sides of the hand, thus holding the inserted hand. As a result, the hand can be arranged at an appropriate position with respect to the kneading member during the operation of the kneading member, and the massage effect can be further enhanced.

According to the present invention, it is possible to massage the hands including the user's fingers with massage pressures suitable for the back of the hand, the palm, and the fingers.
