Description

  The present invention relates to a massage chair provided with a massage mechanism for treating the body.

  Many of the currently popular massage chairs have a backrest that can be pivoted around the back of the seat, and armrests are arranged on the left and right of the seat. These seats and backrests have a built-in massage mechanism that is driven by a motor or compressed air supply. This massage mechanism strikes, kneads, or vibrates a part of the body. It is intended to recover and improve physical fatigue.

  In order to control this massage mechanism, a remote control device having various operation buttons is provided. This remote control device is stored in a storage unit or a holder provided in a seat or an armrest unit, and when using a massage chair, there are devices that are taken out and operated. However, it is difficult for the user sitting on the seat of the massage chair to take out the remote control device from the storage unit or the holder with the posture in which the backrest portion is rotated and tilted backward, it is difficult to reach the storage unit etc. Because of this, it was necessary to wake up and then do these things. (For example, see Patent Document 1)

In order to solve this problem, there are devices in which the remote control device and the remote control mounting / dismounting base are attached to a flexible arm fixed to the backrest portion or a rod-like member pivotally attached at one end to the backrest portion. As a result, the user can operate the remote control device because the remote control device and the remote control attachment / detachment base move together with the rotation operation of the backrest portion even when the backrest portion is rotated and tilted backward. And can be taken out easily. (For example, see Patent Document 2)

After using the massage chair 1, the remote control support arm 15 extending horizontally in the forward direction is rotated downward on the armrest portion 4 by the lock mechanism 19 as shown in FIG. 3 or 4. By holding at an angle of 45 degrees or 90 degrees downward from the horizontal direction, when the next user sits on the seat section 2, the remote control holding section 45, the remote control device 46 and the remote control support arm 15 are It does not get in the way of touching the human body. When the remote control holding unit 45 and the remote control device 46 collide with the armrest unit 4 when the remote control support arm 15 is pushed down, the detent mechanism 35 is operated to operate the operation surfaces of the remote control holding unit 45 and the remote control device 46. 47 needs to be rotated and held so as to face in the left-right direction from the front-rear direction during use.

  Next, another embodiment will be described with reference to FIGS. 7 and 8 using the same components as those in the above embodiment. One side portion of the backrest portion 3 has a mounting portion 50 protruding laterally therefrom, and an extension portion 51 bent from the mounting portion 50 in a right angle direction and extending forward, and having a distal end portion bent upward. One columnar remote control support arm 53 is provided. Unlike the remote control support arm 15 of the above embodiment, the remote control support arm 53 is not provided with the lock mechanism 19. The remote control support arm 53 protrudes forward along the upper portion of the armrest portion 4 because the attachment portion 50 has a short length that protrudes outward from the attachment arm 16 of the first embodiment.

  A support portion 52 is connected to the tip of the extension portion 51. The connection portion is the same as the connection structure between the extension arm 17 and the support arm 18 shown in FIGS. The device 46 can be rotated and held in an angle range of 180 degrees by a detent mechanism 35 as a holding mechanism. Therefore, when the massage chair 1 is in use, the operation surface 47 is opposed to the backrest portion 4 as shown in FIG. When leaving, as shown in FIG. 8, the operation surface 47 of the remote control device 46 is rotated 90 degrees around a substantially vertical axis and turned to the left or right, and touches the body to obstruct the body. It can be held so that it does not become. At this time, the outer side surfaces of the remote control holding unit 45 and the remote control device 46 are positioned at least outward from the inner side surface of the armrest portion 4.

  In order to hold the remote control device 46 in the left-right direction or the front-rear direction, the detent mechanism 35 is not necessarily required, and the extending portion 51 and the support portion 52 that are rotatably provided are screwed. It can be held by providing a lock mechanism for temporarily holding by tightening, or by a frictional resistance at a rotational fitting portion between the extension portion 51 and the support portion 52.
