The folding table/chair bracing frame

The utility model belongs to a kind of folding table/chair bracing frame.

Existing folding seat and folding table are generally the branch amorph, and volume is big, carry inconvenience.

The utility model aims to provide a kind of volume compact, the folding table/chair bracing frame that chair and tea table can be connected as a single entity easy to carry.

The technical scheme that realizes above-mentioned purpose is (referring to implementing illustration): the utility model comprises the chair bracing frame (1 of both sides, rear portion band backrest support rods (13), 5), four sides of chair bracing frame are made up of the Collapsible rack that support bar intersection hinge is connected to form respectively, the corresponding up and down support bar termination of adjacent two sides support respectively in twos hinge in same hinge head (2,7,11,14) form folding flex point, it is characterized in that: two chair bracing frames (1,5) be provided with a bracing frame (3) between, before the table bracing frame, trailing flank is made up of the support (4) that support bar intersection hinge is connected to form respectively, four terminations up and down of support respectively with both sides chair bracing frame before, the preceding upper hinge head (7) of trailing flank correspondence, back upper hinge head (11), preceding hinge head (2) down and back hinge head (14) hinge down connect, the beside of table bracing frame two beside bottoms and chair bracing frame is shared, table bracing frame leading flank, two beside tops are provided with the little X-shaped support (6 that is connected to form by two support bars intersection hinges respectively, 9,12), little X-shaped support bottom two ends is connected with two support bar hinges of lower bracket respectively, the little X-shaped support front upper part termination of two beside respectively with the corresponding termination hinge on the little X-shaped support of adjacent leading flank top in preceding table hinge head (8), the termination, upper back links to each other with a back hinge head (10).

Using method of the present utility model is (referring to Fig. 3, Fig. 4): bracing frame is strutted, seat (16) is fixed on the chair bracing frame, between the forward and backward table hinge head (8) on table bracing frame top, (10), load onto cross bar (15), again desktop (17) is fixed on the folding seat of band tea table in the middle of promptly forming on two cross bars.

The utility model is connected as a single entity folding table/chair, and the beside of junction can be shared, so compact conformation, volume is little, simultaneously collapsiblely draws very little volume in, is easy to carry.
