This massage machine has a massage drive unit that can move up and down within the back of a chair-type massage machine body. A pair of left and right massage members (brush balls) are provided on the upper side of the massage part, and a pair of left and right massage members are also provided on the lower side of the massage drive part.
[0003]
And each massage member is comprised so that it may advance / retreat to the user side by the air cell which expand | swells by supply / exhaust of air.
The air cell is used to move the pair of left and right massage members in the left-right direction, and to move the upper massage member and the lower massage member around the horizontal axis. With things.
[0004]
[Problems to be solved by the invention]
In the prior art, the affected part can be swung in the left-right direction and the affected area can be pinched from the left-right direction, but cannot be pinched in the vertical direction.
In addition, when the body is squeezed in the left-right direction, the body is substantially bilaterally symmetric, so there is no need to consider the arrangement of massage members that are paired left and right.
[0005]
However, when itching in the vertical direction, since the back is not flat in the vertical direction, it may not be possible to properly massage unless the positions of the upper and lower massage members are different from each other.
For example, when the shoulder is massaged, the upper massage member can protrude more effectively from the lower massage member toward the user side. On the other hand, such a disposition is not always good when rubbing other positions or performing other massage operations.
[0006]
This invention is made | formed in view of such a situation, Comprising: It aims at providing the massage machine which can perform an effective up-down direction massage and other massages.

The upper drive means that can advance to the user side while moving the lower massage member between the lower front position on the user side and the lower rear position away from the user, and the lower side in each position of the front position and the lower post position, and a lower driving means for the lower massage member can be advanced to the user side while directing upward, the upper drive means及The lower drive means, the upper massage member and is configured and lower massage member to allow the vertical direction is mutually approach to and separate from operation of the vertical kneading, the upper massage member is in said upper rear position, It is arranged to project to the user side than the lower massage member in the lower rear position, the upper drive means and the lower drive means can be operated independently, and the upper massage member is In a state where the lower massage member is not operated as an upper rear position, the lower massage member is moved to and held at the lower front position, and the lower massage member is repeatedly reciprocated with upward directivity. Machine.
[0008]
According to such a configuration, it is possible to stagnate in the vertical direction, which was not possible conventionally. Moreover, since the upper massage member protrudes toward the user side from the lower massage member, it is preferable that a sense of squeezing the vicinity of the shoulder with a human hand is obtained.
Moreover, since the upper massage member and the lower massage member can independently advance and retract, each massage member can be fitted to the back regardless of the curved state of the back. Furthermore, when the body is pressed only by the upper massage member, the upper massage member protrudes from the lower massage member, so that the lower massage member that does not operate does not contact the body unnecessarily.
[0009]
The upper drive means has an upper base provided so that the upper massage member can be advanced to the user side while directing the upper massage member downward, and the upper base is swung back and forth by moving the upper base back and forth. The massage member is moved back and forth between the upper front position and the upper rear position, and the lower drive means is separate from the upper base, and the user is directed to the lower massage member upward. A lower base provided so that it can be advanced to the side, and swinging the lower base back and forth to move the lower massage member between the lower front position and the lower rear position. The lower masser can be moved forward and backward by swinging the lower base forward without moving the upper massage member as the upper rear position without swinging the upper base forward. Preferably maintained by moving the support member to the lower front position.
Further, it is preferable that the upper masser member and the lower massage member are operated with a time difference between the operation start times of the upper drive means and the lower drive means.
And in this invention, it is preferable that the said lower side drive means shall be comprised so that advancing stop can be carried out to the position which protrudes the said lower side massage member to the user side from the said upper side massage member. In this case, the body can be pressed only by the lower massage member. In particular, the lower drive means is constituted by an air cell that expands and contracts by air supply / discharge to move the lower massage member forward and backward, and drives the lower massage member to perform a hitting operation separately from the air cell. In the case of a device provided with a hitting drive unit, the lower massage member can be hit without unnecessary contact of the upper massage member with the body.
[0010]
Further, when the lower drive means is configured so that the lower massage member can be advanced and stopped at substantially the same position in the advancing and retracting direction as the upper massage member, the upper and lower massage members are substantially on the body. It becomes a flat state, and the body can be hung by moving the massage drive unit up and down in this state.
[0011]
Further, it is preferable that the lower drive means is configured to be able to advance and stop at the position where the lower massage member protrudes toward the user side from the upper massage member, and to be stopped at the position where the advance operation is in progress.
Further, the lower drive means is preferably composed of a plurality of air cells arranged in parallel in the advancing and retreating direction of the lower massage member, and the air cells arranged in parallel are preferably operable independently. Are preferably configured in the same manner.
