When the frontmost second adjustment hole 5011 is aligned with the second locking hole 102, inserting the second locking pin 5012 can The base 501 is fixed on the main bracket 100 to form an unfolded state as shown in FIG. The main support 100 is in a collapsed state as shown in FIG. 3 .

As shown in Figure 3, the multifunctional fitness chair of the present invention is in a folded state, and the backrest 400 is positioned at the rear side of the backrest support 401 for supporting the back of the human body. On the horizontal plane, it is used to support the buttocks of the human body. The blocking mechanism 500 shrinks to a position close to the main support 100, and the connecting rod 300 extends downward in a vertical direction. At this time, the multifunctional fitness chair can be used as an ordinary chair with a small footprint , easy to place.

As shown in Figures 4-5, the connecting rod 300 has two rotation planes that are perpendicular to each other and are perpendicular to the horizontal plane. The position above the mechanism 200 side, as shown in FIG. 5 , the two rotating rods 300 located on the left and right sides of the seat mechanism 200 have the same structure and are independent of each other. The two rotating rods 300 can rotate independently or jointly.

As shown in Figures 6-7, it is the first embodiment of the seat mechanism 200. The seat mechanism 200 includes a seat frame 201 and a seat 202. The seat frame 200 includes three poles, which are respectively a first pole 2011 and a second pole. 2012. The third pole 2013. The above three poles are rotatably connected to each other. When the adjacent poles rotate relative to each other, the range of the angle between the adjacent poles is 0-180°. The first pole When 2011 and the second pole 2012 rotate to the same straight line, the seat 202 is located above the first pole 2011/second pole 2012, which can form a support surface for supporting the bodybuilder. When the support surface is required to be parallel to the horizontal plane, rotate The third pole 2013 supports the first pole 2011 and the second pole 2012 in the vertical direction, as shown in Figure 6; The two poles 2012 are closed and folded, and the first pole 2011 is rotated downward so that the supporting surface is supported obliquely on the ground, as shown in FIG. 7 .

As shown in Figures 8-9, it is the second embodiment of the seat mechanism 200, which is basically the same as the first embodiment, the difference is that the seat frame 201 only includes a first pole 2011 and a second pole 2012 , when it is necessary to make the seat 202 on the first pole 2011 parallel to the horizontal plane, you only need to rotate the first pole 2011 to make it parallel to the horizontal plane, and rotate the second pole 2012 to the vertical direction, and the first pole 2011 Rod 2011 can be supported, as shown in Figure 8; when it is necessary to make the seat 202 on the first pole 2011 and the second pole 2012 form a supporting surface inclined to the horizontal plane for supporting the bodybuilder, only the second One rod 2011 and the second rod 2012 are rotated to the same straight line, and then the support surface is supported obliquely on the ground by rotating the first rod 2011 downward, as shown in FIG. 9 .

As shown in Figures 10-12, the backrest bracket 401 can be inserted on the top of the main bracket 100 after being rotated 180° from front to back, so that the backrest 400 can face forward or backward, and the backrest 400 can rotate around the top of the backrest bracket 401 in addition, so that The backrest 400 can be turned over 360° in the front and rear directions to meet different needs.

As shown in Figures 13-14, it is the third embodiment of the seat mechanism 200, which is basically the same as the first embodiment, the difference is that the seat frame 201 also includes a fourth pole 2014, and the fourth pole 2014 Located between the first pole 2011 and the main bracket 100, the fourth pole 2014 is rotatably connected to the main bracket 100, and the first pole 2011 is rotatably connected to the fourth pole 2014. When the rod 2011 rotates relative to the fourth rod 2014, the range of the included angle between the first rod 2011 and the fourth rod 2014 is 0-180°. When it is parallel to the horizontal plane and lowered to the lowest point, the seat 202 can be rotated to a position approximately on the same plane as the backrest 400 through the rotation of the fourth support rod 2014, so that the seat 202 and the backrest 400 together form a substantially flat and parallel to the horizontal plane. For supporting the supporting surface of the bodybuilder, since the two ends of the fourth pole 2014 are respectively rotatably connected to the main bracket 100 and the first pole 2011, in order to stabilize the supporting surface, the fourth pole 2014 needs to be locked by a locking device. Keeping in the same straight line state as the first pole 2011, the locking device can be realized by existing technology, and it is not the invention point of the present invention, so it will not be repeated here.

As shown in Figure 15-16, the vertical part of the gear bar 502 and the slot of the base are made of square steel, and the gear bar 502 can be inserted into the base 501 after rotating 90°, 180°, 270° with the vertical part as the axis In the slot on the board to suit different needs.
