Description

  The present invention is a chair-type massage machine provided with a leg rest that can be placed in a chair body so that the leg of the user can be placed and the appropriate treatment can be performed on the leg. When the leg resting part moves up and down smoothly, the leg resting part moves smoothly, and the leg resting part is not only used when the user sits on the chair or stands up, but also when the massage function of the leg resting part is not used. It is related with the chair type massage machine which stored the part under the seat part and did not get in the way.

  2. Description of the Related Art Conventionally, massage chairs that can obtain a massage effect while sitting on a chair are known. A typical example of this type of massage chair is one that massages the back of the user with a massage mechanism built into the backrest of the chair body, such as squeezing and striking. Many ottomans (leg rests) having treatment members capable of massaging a user's leg are connected to the front end of a massage chair body.

  For example, there is a chair-type massage machine as shown in FIG. 11 (Patent Document 1) as an ottoman (leg rest) provided with a treatment part capable of massaging the leg part. The machine holds the leg of the user in the leg setting groove 24 provided on the one surface side of the leg mounting portion 13 provided in the chair body 1, and then the treatment bag provided in the leg setting groove 24.

Even in the case where the ottoman is placed in a suspended state, it is inevitable that the convex portion of the ottoman's leg treatment portion protrudes greatly forward due to its structure.

  For this reason, even when the ottoman is not used, there is a sense of incongruity that the protruding portion (convex portion) of the ottoman comes into contact with the calf of the user sitting on the chair body. I couldn't get a comfortable feeling as a chair.

Thus, as a solution to the above problems, there is a massage chair shown in FIGS. 12 to 14 (Patent Document 2). As described in paragraph [0013] of the specification of Patent Document 2, when the massage lever is pressed by the operation lever portion 18 to release the lock lever 16, the ottoman 6 moves its treatment surface 15 forward. It can be rotated so that it tilts backward with the horizontal frame 12b as the center. When the ottoman 6 is rotated to a predetermined angle with respect to the support arms 14a and 14b, the storage stopper 22 protruding outward from the U-shaped frame 11b hits the swing arm 14b on the side close to the ottoman 6 The rotation position where the storage stopper 22 hits is the storage position of the ottoman 6 in the massage chair of this example. The upper portion of the ottoman 6 in the storage position is stored in the storage space 25 below the seat portion 2 of the chair body 1, and all or almost the entire portions of the wall portions 8 and 9 protruding forward are also seated. It is configured to be stored in the storage space 25 below the portion 2.
