DETAILED DESCRIPTION OF THE INVENTION

(8) The present invention will be further described in detail by embodiments with reference to the accompanying drawings.

(9) FIGS. 1-6 show a preferred embodiment of a foldable stool. The foldable stool comprising a stool surface 1 having a bottom surface, and two support legs 2. The stool surface 1 is made of flexible materials being capable of be folded up to form a storage compartment for receiving the two pairs of support legs 2; a plurality of zippers 4 are sewn on faced two edges of the storage bag, so that a bag can be formed. Two support legs 2 are swingly connected to each other, the top of two support legs 2 are respectively connected to the left side and right side of the bottom surface of the stool surface 1 through a plurality of connecting bands or connectors. Each support leg 2 is made of metal tube or composite material tube and is hollow inside which composed of an upper section 21, a middle section 22 and a lower section 23 connected together, and an elastic rope 3 running through inside of each support leg 2 may connect the upper, middle and lower sections 21, 22 and 23 of the support leg 2 together and may also pull the sections apart. Moreover, when the elastic rope is extended, the upper, middle and lower sections 21, 22 and 23 of the support leg 2 are separated with each other and rotatably folded into the storage compartment formed by folding the stool surface 1, and the storage bag is closed by the zipper 4 to form a bag easy to carry around.

(10) The specific structure is as follows: the upper section 21 and the lower section 23 have U-shape, the middle section 22 is straight and has a top end and a bottom end; two ends 211 of the upper section 21 have a smaller diameter relative to the upper section 21 so as to insert into the top end of each tube of the middle section 22, and two ends 231 of the lower section 23 have a smaller diameter relative to the lower section 23 so as to insert into the bottom end of each tube of the middle section 22, accordingly, the upper, middle and lower sections 21, 22 and 23 are detachably connected together, and tightly connected together under the elastic force of the elastic rope 3 to form a roughly rectangular frame, which can make the upper, middle and lower sections 21, 22 and 23 be pulled apart, respectively. Generally, each support leg 2 has two elastic ropes 3 with two ends being positioned and fixed by the connecting pins 6; the two elastic ropes 3 are disposed in two opposite U-shaped routes in the upper, middle and lower sections 21, 22 and 23 of each support leg 2. A connecting hole is disposed at the middle of each tube of the middle section 22, the middle section 22 of one support leg 2 is disposed outside of the other support leg 2, and the middle section 22 of one support leg 2 is rotatably connected to the middle section 22 of the other support leg 2 by two connecting pins 6 inside the connecting holes, so as to make the two support legs 2 be rotatably connected in an X shape. The stool surface 1 is square or rectangular, the stool surface 1 has a lower edge 11 protruding from the bottom surface of the stool surface 1. Generally, the lower edge 11 is sewn and connected to a periphery of the lower surface of the stool surface 1, and may be made of the same flexible material. In order to facilitate folding in half, the lower edge 11 has two slots 12 adjacent to a folding line of the stool surface 1, and further provided with the zipper 4 by sewing. In this way, the peripheries of the storage bag folded will be smooth, which avoids mutual interference and thus makes the bag more fitting and beautiful. Generally, the width of the slot 12 is less than or roughly equal to the sum of two times the height of the lower edge 11 and the height of the zipper 4. The top of the support legs 2 are disposed on the bottom surface of the stool surface 1 and located at the inner side of the lower edge 11, and a plurality of connecting bands 5 for securing the support legs 2 are disposed adjacent to the lower edge 11 on the bottom surface of the stool surface 1. The connecting band 5 can be a canvas band or belt, and there is one or two or even more connecting bands 5. One end of the connecting band 5 is fixed with the bottom surface of the stool surface 1, and the other end of the connecting band 5 is fixed with the bottom surface of the stool surface 1 after going around the upper section 21 of each support leg 2, and may also be fixed by stitching or riveting.

(11) When the stool is in use, the middle sections 22 of the support leg 2 are inserted into the corresponding upper section 21 and the corresponding lower section 23 forming a support leg 2, and the two sets of the support legs 2 are pulled open to form an X-shape, so that the stool surface 1 is unfolded for people to sit and use. When the stool needs to be stored after use, the middle sections 22 are pulled apart from the upper section 21 and the lower section 23, as shown in FIGS. 3 and 4, the stool surface 1 is folded in half, the middle sections 22 rotate by 90 degrees, the upper sections 21, the middle sections 22 and the lower sections 23 are folded and put into a storage bag formed by the stool surface 1, and finally, the bag is closed by the zipper 4, as shown in FIGS. 5 and 6.

(12) In this embodiment, a detailed description is only made to a zipper design. In fact, similar technical effects can be used to replace the zipper 4, such as a hasp 7, a nylon hasp, as shown in FIG. 7.

(13) The protection scope of the present invention is not limited to each embodiments described in this description. Any changes and replacements made on the basis of the scope of the present invention patent and of the description shall be included in the scope of the present invention patent.
