With reference to FIG. 1, a multipurpose workout chair in accordance with the present invention is provided. The multipurpose workout chair not only can be used for exercise, but also can be used as a regular chair. The multipurpose workout chair comprises a backrest 10, two power twisters 20, a seat 30, two support structures 40, two chair legs 50, two connection components 60, and multiple adjustment devices 70. The relative angles or relative positions between components of the multipurpose workout chair in the present invention can be adjusted based on the needs in order to present multiple embodiments and configurations.

In the first embodiment (FIG. 1) of the present invention, a rod is used as the backrest 10, and a cushion pad 10A can be added for releasing the pressures from the body during the exercise. Two opposite ends of the backrest 10 are each respectively connected with one end of a respective one of the power twisters 20. When a user applies forces on the backrest 10, the power twisters 20 would be driven and bent by the backrest 10. As the power twisters 20 are bent, the power twisters 20 naturally generate resilience forces towards the opposite direction of the applied forces, thereby allowing the user to exercise by resistance training.

The support structures 40 are respectively mounted on two opposite sides of the seat 30. Each support structure 40 comprises a first support rod 41 and a second support rod 42. The two chair legs 50 may be a first chair leg 51 and a second chair leg 52. Two ends of the first support rod 41 are respectively connected to one of the connection components 60 and one end of the first chair leg 51 via the adjustment devices 70. Two ends of the second support rod 42 are respectively connected to one of the ends of the second chair leg 52 via the adjustment devices 70 and the first support rod 41. The connection components 60 are each connected to another end of a respective one of the power twisters 20. Said another end of the power twister 20 is opposite the backrest 10, and is configured to connect one of the ends of the first support rod 41.

Then please refer to FIG. 1 and FIG. 2. The multiple adjustment devices 70 comprise two first adjustment devices 71, two second adjustment devices 72, and two third adjustment devices 73. Each one of the first adjustment devices 71 connects a respective one of the first support rods 41 and a respective one of the connection components 60 and is configured to adjust an angle between said one of the first support rods 41 and said respective one of the connection components 60. Each one of the second adjustment devices 72 connects a respective one of the first support rods 41 and one end of the first chair leg 51. The second adjustment devices 72 are configured to adjust an angle between said first support rod 41 and the first chair leg 51. The first adjustment devices 71 and the second adjustment devices 72 are respectively mounted on the two ends of the first support rods 41. Each one of the third adjustment devices 73 connects one of the second support rods 42 and one end of the second chair leg 52. The third adjustment devices 73 are configured to adjust an angle between said one of the second support rods 42 and the second chair leg 52.

Each of the first adjustment devices 71 comprises a first base 711, a second base 712, a threaded component 713, and a detaching spring 714. The first base 711 is connected to the corresponding one of the first support rods 41. A surface of the first base 711 comprises multiple first gear teeth 7111. The second base 712 is connected to the corresponding one of the connection components 60. A surface of the second base 712 comprises multiple second gear teeth 7121.

The detaching spring 714 is mounted between the first base 711 and the second base 712 and is configured to separate the first base 711 and the second base 712. When the first gear teeth 7111 are engaged with the second gear teeth 7121, the first base 711 cannot be rotated with respect to the second base 712. Meanwhile, the first end 7131 of the threaded component 713 and the nut apply forces on the first base 711 and the second base 712 toward each other, and the detaching spring 714 is compressed between the first base 711 and the second base 712. Due to the compression, the detaching spring 714 applies forces toward the first base 711 and the second base 712. When adjustment is needed, the threaded component 713 can be released from the nut and thereby the first base 711 and the second base 712 are separated by the detaching spring 714. Therefore, the first gear teeth 7111 and the second gear teeth 7121 are disengaged and the first base 711 and the second base 712 can be rotated with respect to each other for the adjustment.

The structure and the mechanism of the first adjustment devices 71, the second adjustment devices 72, and the third adjustment devices 73 are similar. Therefore, only the first adjustment devices 71 would be described in this specification. A first base of each second adjustment device 72 is connected to a respective one of the first support rods 41, a second base of each second adjustment device 72 is connected to a respective one end of the first chair leg 51, and the first base and the second base of each second adjustment device 72 can be rotated with respect to each other. A first base of each third adjustment device 73 is connected to a respective one of the second support rods 42, a second base of each third adjustment device 73 is connected to one end of the second chair leg 52, and the first base and the second base of each third adjustment device 73 can also be rotated with respect to each other.
