The base frame is a quadrangular frame formed by connecting four connection poles 5 and four joints 1, 2, 3, 4 at intervals. The joints 1, 2, 3, 4 are formed with first horizontal insertion holes 11, 21, 31, 41 and second horizontal insertion holes 13, 23, 33, 43 into which the connection poles 5 are inserted. Two connecting poles 5 are connected to one joint (i.e. each connecting pole 5 has one joint connected to each end), and the four joints 1, 2, 3, 4 are connected to a square frame. located at the four corners of The joints 1, 2, 3, and 4 further include third insertion holes 14, 24, 34, and 44 that open downward and into which the respective support legs 6 are inserted, and the seat support poles that open upward. 4th insertion holes 12, 22, 32, 42 into which 7, 8 are inserted are formed. A support leg 6 and a seat support pole 7, 8 are connected to each joint 1, 2, 3, 4, respectively.

In this embodiment, the joints 1, 2, 3 and 4 are integral members, and are constructed by connecting two L-shaped hollow curved tubes. The most preferred embodiment is two L-shaped bends with the bends hooked together. Since the two L-shaped curved tubes are hooked together, one of the first horizontal insertion holes 11, 21, 31, 41 and the second horizontal insertion holes 13, 23, 33, 43 is upward. The other is provided below. As shown in FIGS. 1 and 2, the second horizontal insertion holes 13, 23, 33, 43 are higher than the first horizontal insertion holes 11, 21, 31, 41. As shown in FIG. To increase the strength of the joints 1, 2, 3, 4, reinforcing ribs 15, 25, 35, 45 are connected between the outer walls of the two curved tubes.

Further, the third insertion holes 14, 24, 34, 44 of the joints 1, 2, 3, 4 extend at an angle away from the center axis of the base frame from top to bottom. , 3, 4 of the fourth insertion holes 12, 22, 32, 42 extend obliquely away from the center axis of the base frame from the bottom to the top. When the support legs 6 are inserted into the inclined third insertion holes 14, 24, 34, 44 and the seat support poles 7, 8 are inserted into the inclined fourth insertion holes 12, 22, 32, 42, the four inclined The stability of the support leg 6 is increased, and the load bearing capacity of the four inclined seat support poles 7 and 8 is also increased.

In order to facilitate the user to assemble the base frame, the joint has marks 9 for identifying the order of assembly, such as marks "3" and "4" in FIG. 1 and mark "1" in FIG. have As shown in FIG. 1, one same connection pole 5 is inserted between two adjacent joints (for example, joint 1 and joint 2, joint 1 and joint 3, etc.), and a fourth insertion hole that opens upward. The seat support poles 7 and 8 and the support legs 6 can be adapted to each other by matching the opening direction and the inclination angle of the downwardly opening third insertion hole. Thereby, the structure of the joint 1 shown in FIG. 3 and the joint 3 shown in FIGS. 4 and 5 are mirror images of each other, and the structure of the joint 1 and the joint 2 are also mirror images of each other.

Each connection pole 5 in this embodiment has a hollow square shape. Since the connecting pole 5 is a hollow pole, the production raw material can be saved and the strength of the connecting pole 5 can be guaranteed. The square connecting pole 5 and the joints 1, 2, 3 and 4 have a certain angle when they are inserted. The connection pole can be more easily kept parallel, and when the square connection pole is inserted into the matching joint, the square connection pole is not easy to rotate, and the connection of the square frame can be stable.

As shown in FIG. 2, the top end of each support leg 6 is connected with the joints 1, 2, 3, 4 and the bottom end extends downwards. Each support leg 6 includes an upper support leg 61 and a lower support leg 62 , and the upper support leg 61 is formed with a first connection hole 611 and a second connection hole 612 . A first elastic pin 613 and a second elastic pin 614 are engaged with the first connection hole 611 and the second connection hole 612, respectively (see FIGS. 6 and 7). The lower support leg 62 is formed with two second positioning holes 621 (the number of second positioning holes may be increased if necessary). When the upper support leg 61 is in the cavity of the lower support leg 62 and the second elastic pins 614 are positioned in the different second positioning holes 621, the support legs 6 have different lengths. The support legs support the entire base frame and keep the base frame and the ground at a constant height. By adjusting the positioning of the second elastic pin 614 to different second positioning holes 621, the height between the base frame and the ground can be changed, which is suitable for users of different heights. The joints 1, 2, 3, 4 are further formed with first positioning holes 16, 26, 36 (the first positioning holes of the joint 4 are not shown) that are compatible with the above-described first elastic pins 613, Since the first elastic pin 613 is positioned in the first positioning holes 16, 26, 36, the support leg 6 can be easily inserted into the joints 1, 2, 3, 4 accurately, and the inclination angle and insertion depth of the support leg 6 can be adjusted. Since the height can be further fixed, it can be placed on the ground more stably.

The bottom end of each seat support pole 7,8 is connected with a joint 1,2,3,4 and the top end extends upwards. The seat support poles 7 and 8 include two adjacent long seat support poles 8 and two adjacent short seat support poles 7 . The elongated seat support pole 8 is a joint pole that can be disassembled and assembled, and is composed of a first pole 81 and a second pole 82 joined by a connecting member 83 (see FIG. 2). The four seat support poles provide multiple points to support the seat, allowing the seat to be designed to better fit the shape of the human body. In addition, when a seat is attached to the top end of two long seat support poles 8 adjacent to each other, the user can lean on the back and the comfort of the leisure chair can be enhanced.
