However, the fixed type footrest device 54 is designed so that the footrest device 54 interferes with the vehicle body wall, the front and rear rotating seats, etc. when the rotary seat to which the fixed footrest device 54 is attached is rotated. Therefore, not only the design of the rotary seat itself is restricted so that the footrest 55 and the arm 56 of the footrest device 54 do not abut on the footrest 51 as shown in FIG.
In the fixed-type footrest device 54, since the footrest 55 always projects below the stool main body 52, the tip of the footrest device 54 easily hits the knees or feet of the passenger when the rotary stool rotates, which is very dangerous. There was a problem that there is.

Further, in a flip-up type footrest device which is linked to and interlocks with a release device of a footrest device via a relay member such as a cable and a pedal for releasing rotation of the rotary seat, the backrest is connected to the pedal. It is also necessary to provide a relay member for releasing the seat lock which inclines the shears. For example, a rotating stool for three people has at least six relay members, and these relay members are formed when the stool body rotates. However, there has been such a problem that the footrest device is apt to be broken due to being entangled in the footrest or the relay member itself being cut.

[0005] The present invention has been made in view of the above problems, and a flip-up type footrest device is mounted on a rotary stool and a single relay member is used to rotate the stool body. It is an object of the present invention to provide a rotary stool capable of automatically flipping up a plurality of stools.

[0006]

In order to achieve the above-mentioned object, a rotary stool footrest device according to the present invention comprises a stool body frame mounted on a footrest fixed on a floor via a rotary device. A support bracket configured at the rear of the underframe in a rotary stool configured to be freely rotatable in forward and reverse directions.

The structure is formed on the side of the support bracket, and the locking operation of the locking mechanism is released by the stepping down operation of the pedal for releasing the rotation stopping operation of the underframe with respect to the footrest, and is used with an appropriate predetermined force. by lifting the foot hanging in the posture in which the subject matter that has been configured to be able to release the locking operation of the lock mechanism.

[0007]

According to the above structure, when the footrest is pushed down to a predetermined position, the fitting edge formed at the base end of the arm for supporting the footrest becomes a right angle or an acute angle. From
The locking mechanism is operated so that the bent stoppers are fitted to each other and can be reliably fixed to the use position, and the passenger can place his feet on the footrests. Also,
When the pedal is depressed to change the direction of the seat, the locking operation of the lock mechanism that fixes the footrest at the use position is released, and the seat is jumped up to the storage position by the urging force of the elastic member. In addition, when the footrest is used at a position where the footrest is used, the footrest can be jumped up to the storage position with a predetermined force by appropriately lifting the footrest.
