Detailed description of the invention
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
As shown in Figure 1 to Figure 3, the chair frame of a kind of flexible director's chair of the utility model comprises: the left support frame 1 be symmetrical set and right support frame 2, connect two groups of cross pipes 3 of left support frame 1 and right support frame 2 front and back end.
Symmetrically arranged bipod pipe 11,21 before and after left support frame 1, right support frame 2 comprise respectively, connect the end pole 12,22 of bipod pipe 11,21, front and back end fixing welding a connecting piece 121,221 respectively of the opposite side of the end pole 12,22 of left and right bracing frame 1,2.The top of each pin pipe 11,21 connects one first telescoping tube 13,23 respectively, and each first telescoping tube 13,23 to be scalablely connected with one second telescoping tube 14,24 respectively, makes the first telescoping tube 13,23 and second telescoping tube 14,24 form telescopic sleeve structure.Wherein, second telescoping tube 14, 24 can be divided into front second telescoping tube 141, 241 and rear second telescoping tube 142, 242, rear second telescoping tube 142, the height of 242 is higher than front second telescoping tube 141, the height of 241, second telescoping tube 142 after making, 242 exceed front second flexible 141, the part of 241 is directly as the backrest support rods of this chair frame, front second telescoping tube 141, 241 tops and rear second telescoping tube 142, a handrail tube 15 is provided with between 242, 25, handrail tube 15, the below of 25 is provided with and connects front second telescoping tube 141, 241 with rear second telescoping tube 142, the seat pipe 16 of 242, 26, front second telescoping tube 141, 241 with rear second telescoping tube 142, the relative position of 242 is provided with a curved support plate 17, 27, sit pipe 16, the rear and front end of 26 is located at front and back curved support plate 17 respectively, on 27, avoid sitting pipe 16, 26 directly fix in telescopic tube, cause the distortion of telescopic tube, affect condensation smooth degree.Front and back end fixing welding a connecting piece 161,261 respectively of seat pipe 16,26 opposite side of left and right sidesing supporting frame 1,2.
Each group of cross pipe 3 connects the rear and front end of left support frame 1 and right support frame 2 respectively, and each cross pipe 3 comprises the pole 31,32 of two mutual cross-articulation in middle part.The end of two poles 31,32 of front cross pipe 3 is articulated with respectively to be sat on the brace 161,261 in pipe 16,26 front and the brace 121,221 in end pole 12,22 front, and the end of two poles 31,32 of rear cross pipe 3 is articulated with respectively to be sat on the brace 161,261 at pipe 16,26 rear and the brace 121,221 at end pole 12,22 rear.
Consult shown in Fig. 4 and Fig. 5, when the utility model uses, fixing on the seat pipe 16,26 chair cloth being set in this chair frame, handrail tube 15,25 the right and left of left and right two bracing frames 1,2 is pulled open, two support bars 31,32 of cross pipe 3 are made to launch to form X shape, left and right bracing frame 1,2 can strut by two support bars 31,32, drive the mutual fit of telescopic tube of left and right bracing frame 1,2 simultaneously, during the two complete fits of telescopic tube, two support bars 31,32 are located, realize the expansion location of this director's chair chair frame, as shown in Figure 1.When the director's chair launched will be folded, as long as two left and right bracing frames 1,2 are involutoryly drawn close, the telescopic tube action of left and right sidesing supporting frame can be driven while two support bars 31, the 32 mutual intersection closing of cross pipe 3, the first telescoping tube 13,23, second telescoping tube 14,24 of telescopic tube is made to launch gradually to elongate, until left and right sidesing supporting frame is bonded to each other, this director's chair is flat, is folded state, consults shown in Fig. 5.
As shown in Figure 6, the utility model director's chair also can arrange at least one midfoot support frame further, thus form the Foldable chair that can supply many people seating, as shown be and there are two midfoot support framves 4, 5, each midfoot support frame 4, the structure of 5 is with left, right support frame 1, the structure of 2 is identical, no longer repeated, described cross pipe 3 includes three groups, wherein one group of cross pipe 3 is in order to connect left support frame 1 and the midfoot support frame 4 near left support frame 1, second group of cross pipe 3 connects two midfoot support framves, 3rd group of cross pipe connects midfoot support frame and the right support frame of close right support frame, when folding, can by left support frame, midfoot support frame and right support frame are received and are close together.
In sum, the chair frame structure of the utility model director's chair mainly utilizes cross pipe to coordinate a left side, the telescopic tube of right support frame realizes expansion and the folding of this director's chair, rear telescopic tube extends directly to upper the backrest pole forming director's chair, not only make the overall structure of this director's chair simpler, overall support force can be strengthened simultaneously, and cross pipe and seat pipe and the upper directly fixing brace of end pole are hinged and can avoid cross pipe directly and the hinged distortion causing telescoping tube of telescoping tube, brace structure is simple, it is directly welded on seat pipe and end pole, and not only production and processing technology is simple, support strength is large, existing director's chair support strength can be improved inadequate, baroque shortcoming.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
