Description

  The present invention relates to a massage chair provided with an ottoman.

  Conventionally, a massage chair capable of obtaining a massage effect while sitting on a chair is known. A typical massage chair is one in which a massage mechanism built mainly in the backrest of the chair body massages the user such as squeezing and hitting, but in recent years, the front end of the chair body Many have been proposed in which an ottoman is connected to (see Patent Document 1). This ottoman holds a leg portion of the user on a leg treatment portion provided on one side of the ottoman and drives a treatment means such as an air bag provided on the leg treatment portion, thereby allowing a leg such as a calf to move. Appropriate massage is given to the department treatment area.

In the massage chair provided with the ottoman as described above, it is necessary to form the ottoman's leg treatment part so that the user's leg is fitted, and therefore the ottoman is positioned in a state where it is suspended from the front end of the chair body. Even in such a case, it was inevitable that the leg treatment part of the ottoman would protrude greatly forward. For this reason, even when not using the ottoman, there is a problem that the protruding part of the ottoman comes into contact with the calf of the user sitting on the chair body, and a comfortable use feeling as a chair cannot be obtained. .

Various massages such as massage and hitting are performed on the back of the user. In addition, since the front-rear direction in the text is based on the direction seen from the user seated on the chair body 1, the rear side is the side where the backrest part 3 is located with respect to the seat part 2. Yes, the front side is the side opposite to the side where the backrest 3 is located with respect to the seat 2.

  The ottoman 6 is provided with a leg treatment portion 7 into which a user's leg portion is fitted on a treatment surface 15 that is one side thereof. The leg treatment part 7 has a central wall part 8 projecting from the central part thereof, and outer wall parts 9 projecting from both outer parts sandwiching the central wall 8, and the central wall part 8 and the outer walls on both sides A leg holding groove 23 is formed between each portion 9 and an air bag (not shown), for example, is incorporated in the central wall 8 or the outer wall 9 as a treatment means. And as shown to Fig.1 (a), the ottoman 6 was located so that it might hang down from the front end of the chair main body 1, and the treatment surface 15 which provided the leg treatment part 7 of the ottoman 6 was made to face the front. In this state, the user who is sitting on the seat 2 inserts his / her lower leg into the leg holding groove 23 of the leg treatment section 7 to supply / exhaust the airbag, In particular, the leg treatment part 7 is caused to squeeze and massage the calf part of the lower leg part.

  As shown in FIG. 4, the frame portion 10 incorporated in the ottoman 6 includes a pair of left and right U-shaped frames 11 (hereinafter referred to as the left U-shaped frame 11a, 11a, The right U-frame in the figure is 11b) and a pair of upper and lower horizontal frames 12 connecting the ends of the U-frames 11a, 11b on both sides (hereinafter, the upper horizontal frame in the figure is 12a, the lower in the figure) The horizontal frame on the side is 12b) and the vertical frame 13 which is located on the rear side of the central wall 8 by connecting the central portions of the side frames 12a and 12b arranged side by side. ing. One end side of a pair of left and right swing arms 14 (hereinafter, the left swing arm in the figure is 14a and the right swing arm in the figure is 14b) is located at the front end of the chair frame 26 built in the chair body 1. The front end of the chair body 1 and the ottoman 6 are connected to each other by supporting the frame portion 10 of the ottoman 6 on the swing arms 14a and 14b.

  The frame unit 10 is supported by the swing arms 14a and 14b so that both end portions of the horizontal frame 12b arranged on the lower side of the frame unit 10 are centered on the lower ends of the swing arms 14a and 14b. While being connected rotatably, it carries out by engaging the both ends of the horizontal frame 12a distribute | arranged to the upper side of the frame part 10 with the upper end part of each rocking | fluctuation arm 14a, 14b. The upper horizontal frame 12a is locked so that it cannot be rotated rearward by a lock lever 16 attached to one swing arm 14a, and is extended to the other swing arm 14b. The front stopper 17 is used to lock the front side so that it cannot be rotated forward.

  As shown in FIG. 5, the lock lever 16 described above has a shape in which the front end side forms an operation lever portion 18 and the rear end side forms a lock portion 19 that is bent downward, and between the operation lever portion 18 and the lock portion 17. Is connected to the inner surface of the swing arm 14a so that the operating lever 18 is pulled upward, the lock 19 locks the horizontal frame 12a from the rear side, The entire ottoman 6 cannot be rotated rearward around the horizontal frame 12b. A return spring 20 is attached as an urging means above the lock lever 16 on the inner peripheral surface of the swing arm 14a, and the return spring 20 urges the lock portion 19 side of the lock lever 16 downward so that the lock lever 16 is maintained, and when a downward pressing force is applied to the operating lever portion 18, the lock portion 19 side moves upward to release the locked state. The front stopper 17 described above is projected forward from the upper end of the swing arm 14b, and has a locking portion 21 whose tip is bent inward. The front stopper 17 locks the horizontal frame 12a from the front side by the locking portion 21, and disables the rotation of the frame portion 10, that is, the entire ottoman 6 to the front side around the horizontal frame 12b.

  Thus, when the operation lever portion 18 is pressed to release the lock by the lock lever 16, the ottoman 6 is rotated so that the treatment surface 15 is tilted rearward from the state where the treatment surface 15 is directed forward with the horizontal frame 12b as the center. Can do. 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 will be stored in the storage space 25 below the section 2. Therefore, when the leg massage is not performed, the ottoman 6 is tilted rearward around the lower horizontal frame 12b from the state where the treatment surface 15 faces forward, and is positioned in the storage space 25. In particular, the protruding portion of the ottoman 6 (that is, the wall portions 8 and 9) does not give a sense of incongruity to the user's calf sitting on the seat 2, and a comfortable feeling as a chair is obtained. is there. Of course, when it is desired to perform leg massage, the ottoman 6 in the storage space 25 is raised and rotated so that the upper part moves forward and upward, and the upper lateral frame 12a hits the front stopper 17. The lock lever 16 may be locked from the rear side at the position, and the airbag may be prevented from shrinking by fitting a calf into the leg treatment portion 7 of the ottoman 6 in such a state that the lock lever 16 is held so as not to rotate forward and backward. Is as described above.

  And in the massage chair of this example, the swing arms 14a and 14b are connected to one end of the swing arms 14a and 14b supporting the ottoman 6 and the front end of the chair body 1 so as to be rotatable in the front-rear direction. The chair body 1 is rotatable with respect to the chair body 1 so that the lower part of the chair body 1 moves forward and upward from the state of hanging from the front end of the chair body 1. As a result, the ottoman 6 supported by the swing arms 14a and 14b swings so that the lower portion thereof moves forward and upward from the state shown in FIG. 1A, and the legs of the ottoman 6 as shown in FIG. The treatment surface 15 provided with the treatment part 7 is in a state of facing forward and upward. In this way, by making the ottoman 6 swingable integrally with the swing arms 14a and 14b, the user can appropriately select the swing position of the ottoman 6 and the tilt position of the backrest portion 3 with a desired posture. A massage can be performed.

  To change the swing position of the ottoman 6 and the tilt position of the backrest 3, the link mechanism 24 disposed below the seat 2 is operated by a control unit (not shown) based on the button operation of the user. Is done. Here, the massage chair of the present example is turned on when the upper portion of the ottoman 6 (specifically, the horizontal frame 12a) is in a position where it is non-rotatably locked to the swing arms 14a and 14b by the lock lever 16. A detection switch (not shown) that is turned off when the lock lever 16 is released and tilted rearward is provided. When the detection switch is turned off, the user presses the ottoman 6. A control unit is provided so that even if a button operation is performed so as to be swung, this is canceled and the swinging arms 14a and 14b are not rotated. Then, a detection means for detecting whether or not the ottoman 6 is in a storage position tilted with respect to the swing arms 14a and 14b, such as the detection switch, and a detection means such as the control section, the ottoman. Control means for prohibiting the rotation of the swing arms 14a, 14b relative to the chair body 1 when it is detected that the ottoman 6 is in the stowed position, and swings when the ottoman 6 is tilted backward. The swing limiting means for prohibiting the rotation of the arms 14a and 14b can be configured, and thus the upper portion of the ottoman 6 tilted to the storage position when not in use is pulled out forward and set in a usable state. The ottoman 6 is swung forward only when the ottoman 6 is swung forward to prevent troubles caused by using the ottoman 6 in an inappropriate state. 6 If not set to a usable state in which it is possible to notice it to the user.
