Detailed ways

Referring to Fig. 1 and shown in Fig. 2, the improved bamboo cantilever chair structure provided by the utility model is composed of several elongated first bamboo materials 1, second bamboo materials 2, third bamboo materials 3 and several first supplementary materials. The strengthening element 5A, the second reinforcing element 5B and the third reinforcing element 5C form a seat unit including at least a bottom A, a support portion B and a seat portion C. Wherein, the first bamboo material 1, the second bamboo material 2, and the third bamboo material 3 are all processed and shaped into long strips. In the embodiment shown in Fig. 1 and Fig. 2, the first bamboo material 1 is formed into a relatively large L-shaped, which has a first arc edge 11 and a first straight edge 12 with an acute angle, and a protruding heel 14 is further extended at the lower end bend of the first bamboo material 1; the second bamboo material 2 is formed to be opposite Smaller L-shape, which has a second arc edge 21 and a second straight edge 22 with an acute angle; the third bamboo material 3 is also shaped into an L shape, with a third arc edge with an obtuse angle 31 and the third straight edge 32 . The first reinforcing element 5A, the second reinforcing element 5B and the third reinforcing element 5C are all elongated.

When the utility model is combined into a seat unit, the third straight edge 31 of the third bamboo material 3 is stacked above the first straight edge of the first bamboo material 1, and between the third arc edge 31 and the first arc edge 11 Form a separated angle, at least one first reinforcing element 5A is fixed between the first straight side 11 and the third straight side 31 , and part of the first arc side 11 and the third arc side 31 are pierced Fix at least one second reinforcing element 5B, so that the first straight side 11 and the third straight side 31 form a hollow seat bottom A, so that the bottom A has better elasticity, and the first arc side 11 and the third arc A gradually changing first space 13 is formed between the sides 31, and is supported by the heel 14 to prevent the person sitting on it from falling backwards. In addition, the second arc edge 21 of the second bamboo material 2 is parallel to the first arc edge 11, and the second straight edge 22 is placed against the upper end surface of the third arc edge 31, and then the first arc edge 11 and the second arc edge Between the arc edges 21, and between the second straight edge 22 and the third arc edge 31, at least one third reinforcing element 5C is fixed, and the third reinforcing element 5C is at least located at the turning point of the second arc edge 21, and Another third reinforcing element 5C is located between the second straight side 22 and the third arc side 31 near the end, so that a gradually changing second space 33 is formed between the second straight side 22 and the third arc side 31 , and The second space 33 communicates with the first space 13 , so that the seat B has better strength near the rear end, and the seat C and the supporting part B have excellent elasticity. When the utility model is combined into a cantilever chair, the aforementioned seat units are arranged in parallel, and then the first reinforcing element 5A, the second reinforcing element 5B and the third reinforcing element 5C are used to fix in series. The utility model can also fix a fourth bamboo material 4 on both sides of the assembled cantilever chair, so that the sitter is more comfortable.
