Description

  The present invention relates to a foot massage machine that can be reversed and moved.

In a conventional technique, a massage chair not only can massage the back and buttocks of the human body, but also includes a foot massage device that can massage the lower limbs of the human body (Patent Document 1). reference).
Such a foot massage device is generally arranged in the front part of the massage chair, and a user who performs massage on the back and buttocks can simultaneously perform a massage by extending the legs and calves into the foot massage device. In order to be able to use the foot massage device as a footrest, the contractor arranges the foot massage device on the support frame with a pivotal connection, and if the user does not need foot massage, the foot massage device is used. Inverted, the back of the foot massage device can be used as a footrest. However, during foot massage, the user's legs and calves must all be extended into the foot massage device, so the distance from the massage chair of the foot massage device is relatively long. When using, when the user tries to place the calf on the back of the foot massage device, the distance from the massage chair of the foot massage device is required to be relatively close.

Therefore, unless the user moves the support frame and pulls the foot massage device closer, it cannot be used comfortably as a footrest, which is complicated in terms of use.

Even if the lock piece 12 is locked and the user loosens the handle 39, the lock piece 12 becomes inoperable. At this time, if the user reverses the footgrip device 2 clockwise, The gear 6 also moves toward the near end at the same time under the meshing action of the rack gear 7.

When the gear 6 rolls and approaches the near end, the push lever 30 located on the right side on the gear 6 pushes and moves the left fork 33 on the mounting plate 14, and the lock block 34 on the fork 33 is moved to the left lock piece. In this case, the lock piece 12 on the left side is inserted into the lock groove 11 located on the right side of the gear 6 in the upward direction under the action of the spring 16, and the gear 6 is locked again. Then, the foot massage device 2 is locked in the footrest state.
FIGS. 12, 13, 14, and 15 are structural views of the footrest state. Similarly, when the user pulls the handle 39, the lock mechanism 8 can be released and the foot is counterclockwise. When the device 2 is reversed, the gear 6 rolls to the far end.

When the gear 6 rolls and approaches the far end, the push lever 30 located on the left side on the gear 6 can move the right fork 33 on the mounting plate 14 to move the lock block 34 on the fork 33 to the right lock piece. In this case, the right lock piece 12 is inserted upward into the lock groove 11 located on the left side of the gear 6 under the action of the spring 16, and the gear 6 is again turned on. Lock and lock the foot massaging device 2 in the foot massaging state.
