FIG. 1 is a side view of a preferred embodiment of the present folding chair in an unfolded state; FIG. Figure 3 is a front elevational view of the preferred embodiment in a deployed state; Figure 4 is a partial enlarged view of Figure 3; Figure 5 is a partial perspective view of the preferred embodiment illustrating a support FIG. 6 is a view similar to FIG. 1 , illustrating that the inclination of the seat back bracket is adjustable by a plurality of hooks of the support member; and FIG. 7 is the preferred embodiment. A side view in a folded state.

Referring to FIG. 1 , FIG. 3 and FIG. 5 , a preferred embodiment of the folding chair 100 of the present invention comprises a main frame body 1 , a positioning rod 2 , a leg unit 3 , and a A seat back bracket 4, a support member 5, an elastic member 6, a mat 7, and a back cushion 8.

Referring to FIG. 1 , FIG. 2 and FIG. 5 , the main frame body 1 includes a main body portion 11 , a protruding portion 13 connected to the main body portion 11 , and two side plate portions 12 connected to the main body portion 11 and spaced apart from each other. The protrusion 13 has a cylinder 131 and a two-piece body 132. The column 131 extends from the body portion 11 toward the rear side (the left side of FIG. 2). The sheets 132 are spaced apart from one end of the column 131 away from the body portion 11 and extend parallel to the rear side. The positioning rod 2 is bridged to the sheets 132. The side plate portions 12 extend from the main body portion 11 toward the front side (the right side of FIGS. 1 and 2) in parallel with each other. Each side plate portion 12 has a guide groove 121 with an opening facing downward. The seat cushion 7 is provided on the side panel portion 12.

Referring to FIGS. 1 to 4 , the leg unit 3 includes an outer leg 32 pivotally connected to the side plate portions 12 , and an inner leg 31 pivotally connected to the outer leg 32 . The inner leg 31 has two spaced apart first poles 311, a first rail 312 and a second rail 313 connected to the first poles 311, and two locking members 314. The second crossbar 313 is for abutting the floor 200 on which the folding chair 100 is placed. Each of the fasteners 314 has a head 315 and a stem 316 coupled to the head 315. The rod portions 316 of the fasteners 314 can be respectively passed through the guide grooves 121 of the side plate portions 12 and screwed to the two ends of the first cross bar 312, and the heads 315 of the fasteners 314 can respectively Both ends of a cross bar 312 collectively sandwich the corresponding side plate portion 12 so that the inner leg 31 can be disposed on the side plate portion 12 without moving relative to the side plate portion 12. Thereby, when the user lifts the folding chair 100 upward, the inner leg 31 is not separated from the side plate portion 12.

The outer leg 32 has two spaced apart second poles 321 and a third crossbar 322 and a fourth crossbar 323 that are spaced apart from each other. The fourth crossbar 323 is for abutting the floor 200 on which the folding chair 100 is placed. Both ends of the third crossbar 322 are pivotally connected to the side plate portions 12, respectively. The second uprights 321 are pivotally connected to the first uprights 311, respectively. The inner leg 31 and the outer leg 32 have an X-shaped configuration in FIG.

Referring to FIGS. 1 and 2 , the seat back bracket 4 is pivotally coupled to the main body portion 11 of the main frame body 1 to be pivotable relative to the main frame body 1 . The back cushion 8 is disposed on the seat back bracket 4, and is pivotable relative to the main frame body 1 by the seat back bracket 4 interlocking.

Referring to Figures 1, 2 and 5, the support member 5 and the backrest cushion 8 are located on opposite sides of the seatback bracket 4. The support member 5 includes a base portion 51 pivotally connected to the seat back bracket 4, and a plurality of hook portions 52 disposed on the base portion 51. The base portion 51 has an elongated shape, and the hook portions 52 are provided on the base portion 51 at intervals in the longitudinal direction of the base portion 51. Each hook portion 52 can be detachably hooked to the positioning rod 2. When any hook portion 52 of the support member 5 is hooked on the positioning rod 2, the seat back bracket 4 can be supported by the support member 5. Referring to Figures 1 and 6, the seat back bracket 4 can be adjusted to be located at a plurality of upright positions having different inclination angles, and the upright positions respectively correspond to the hook portions 52. That is to say, the seat post 2 can be adjusted through different hook portions 52 to adjust the seat back bracket 4 to have different inclination angles. Taking FIG. 1 and FIG. 6 as an example, the seat back bracket 4 of FIG. 1 is adjusted to an upright position with a small inclination angle, and the seat back bracket 4 of FIG. 6 is adjusted to an upright position with a large inclination angle.

Both ends of the elastic member 6 are respectively connected to the seat back bracket 4 and the branch Support 5. The elastic member 6 is a spring in this embodiment, the purpose of which will be described later.

The folding chair 100 shown in Figures 1 to 4 and Figure 6 is in an unfolded state. Next, how the folding chair 100 is switched from the unfolded state to a folded state will be described with reference to FIG. First, the seat back bracket 4 and the back cushion 8 are pivoted in the direction of the arrow A of FIG. 5 so that the seat back bracket 4 is placed in a horizontal position and overlaps the seat cushion 7. Next, the lock 314 of the inner leg 31 is unscrewed away from the end face of the first crossbar 312, and the lock 314 is separated from the guide groove 121 of the side plate portion 12. Finally, the inner chair leg 31 and the outer leg 32 are respectively moved in the direction of the arrow B and the arrow C of FIG. 5 to complete the folding chair 100 in a folded state. It is added that, in the folded state, the elastic member 6 can provide a resilient force of the support member 5 to be reset, so that the support member 5 is held adjacent to the seat back bracket 4 without shaking.

In summary, the folding chair 100 of the present invention allows the folding chair 100 to be folded and unfolded by the mutual cooperation of the positioning rod 2 and the supporting member 5, and the folding chair unit 3 is convenient for folding and unfolding, and the chair is made The inclination angle of the back bracket 4 is adjustable, so that the purpose of the present invention can be achieved.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
