DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

Example 1: Folding Table

(13) Referring to FIGS. 1 to 4, a folding table is shown that includes two main parts: a tabletop 100 made of fabric and a support section 200 that supports the tabletop. The support section 200 includes: an upper connecting plate 1, a lower connecting plate 2, a shaft rod 3, tabletop support rods 4, connecting rods 5, and ground support rod 6. One end of several tabletop support rods 4 is hinged on the lower connecting plate, and the other end is used to support the tabletop 100. One end of the corresponding number of connecting rods 5 is hinged on the tabletop support rods 4, and the other end is hinged on the upper connecting plate 1.

(14) There are several ground support rods 6, generally three to six are better, and the number of tabletop support rods 4 and connecting rods 5 is a multiple of or equal to the number of ground support rods 6, which means that the tabletop 100 needs to have enough support. Four tabletop support rods 4 can support a quadrilateral tabletop, and eight can support an octagonal tabletop. Obviously, the more the support, the flatter the tabletop. The ground support rods 6 are considered to be able to firmly support themselves on the ground. Three rods are the minimum, and the more rods the better the stability. For example, for the octagonal table top 100, four or eight ground support rods 6 can be chosen. If four ground support rods 6 are used, a tabletop support rod 4 will be required with a ground support rod 6. The tabletop support rod 4 and the ground support rod 6 are evenly distributed on the circumference of the upper plate and the connecting plate to achieve a balanced support effect. As for the folding table with an odd number of tabletop support rods 4, it needs to be supported by the same number of ground support rods 6.

(15) The ground support rod 6 passes through a slide bushing 41 positioned on the tabletop support rod, and the upper end is hinged on the upper connecting plate 1 or the connecting rod 5, as shown in FIG. 4. In this example, the upper end of the ground support rod 6 is hinged on the connecting rod 5. It can provide the space occupied by directly hinging on the upper connecting plate 1. In other words, the connecting rod 5 has a small caliber, which saves more space. With this, enough connecting rods can be distributed on the circumference of the upper connecting plate 1 with a smaller caliber to satisfy the need to support the tabletop 100. In addition, the upper end of the ground support rod 5 is hinged on the connecting rod 5, which can also adjust to a more reasonable angle and height of the ground support. As the tabletop support rod 4 opens, the ground support rod 6 can slide along the slide bushing 41 to open outward. Several ground support rods 6 are evenly distributed on the circumference centered on the shaft rod 3 to support the whole structure.

(16) The shaft rod 3 plays the role of guiding and restraining, while also providing a positioning basis. One end of the shaft rod 3 is locked on the upper connecting plate 1, the other end penetrates the lower connecting plate 2, and a locking kit 7 is provided on the lower connecting plate 2 at the penetrating end. The shaft rod 3 constitutes the constraint relationship between the upper and lower connecting plates 1 and 2 and is positioned by the locking kit 7. The locking kit 7 involved can be the prior art shown in the CN201920261426.0 patent. It includes a nut sleeve 71 fixed at the design position of the shaft rode 3 and a hollow hand-adjusting bolt 72. The manual-adjusting bolt 72 is rotated and positioned on the lower connecting plate 2. The manual-adjusting bolt 72 can be screwed into the nut sleeve 71. The distance between the upper and lower connecting plates 1 and 2 is gradually shortened, and the tabletop 100 is gradually tightened. Reverse this operation until the manual-adjusting bolt 72 is disengaged with the nut sleeve 71. The lower connecting plate 2 descends to the limit, and forms the folded state as shown in FIG. 3.

(17) In other words, the upper connecting plate 1 and the lower connecting plate 2 move towards each other, and the tabletop support rod 4 is in an open state to support the tabletop, as shown in FIG. 2. The upper connecting plate 1 and the lower connecting plate 2 move against each other, and the tabletop support rod 4 is in a folded state. As a single-function table, the upper connecting plate 1 can also support the center of the flexible fabric tabletop 100 without being prominent on the table top.

Example 1: Folding Table with Sunshade Combination

(18) Referring to FIGS. 5 to 9, a further embodiment of a folding table is shown with sunshade combination, including a sunshade 300 and the folding table in the first example. The sunshade 300 has a sunshade pole 301, a sunshade frame 302 and a sunshade surface. Because the sunshade surface is not involved in this description, it is omitted in the figure for clarity. The sunshade pole 301 supports the sunshade frame 302, and the sunshade frame 302 supports the sunshade surface to open and close. The sunshade 300 itself is a conventional technology, but the key lies in the matching structure of the sunshade and the folding table. For this reason, the support section 200 of the folding table needs to be adjusted appropriately. When opened, the shaft rod 3 extends upwardly to receive the sunshade pole 301. The specific structure is as follows.

(19) In the support part 200 of the folding table, the lower end of the shaft rod 3 is locked on the lower connecting plate 2. The upper end passes through the upper connecting plate 1, and the upper end is provided with an upper inclined section 31, while the corresponding locking kit 7 is arranged on the upper connecting plate 1, as shown in FIG. 6 and FIG. 7.

(20) The lower end of the sunshade pole 301 of the sunshade is provided with a lower inclined section 303. The lower inclined section 303 and the upper inclined section 31 have the same angle X with the respective center lines. The sunshade pole 301 and the shaft rod 3 are inclined downward by means of the upper inclined section 31 jointing with the lower inclined section 303. This enables the sunshade pole 301 to be adjusted in the range from being upright to tilting twice the included angle X. A locking mechanism 8 is also provided at the connecting joint of the sunshade pole 301 and the shaft rod 3 to lock the inclination angle of the sunshade pole 301 based on the angle of sunlight.

(21) In order to reduce the shearing force of the locking mechanism 8, the shaft rod 3 and the sunshade pole 301 adopt a large and small tube matching structure. The caliber of the shaft rod 3 is larger than that of the sunshade pole 301. The ends of the two connecting sunshade poles 301 insert into the shaft rod 3. The locking mechanism 8 is locked on one side of the shaft 3, that is, it is chosen to be locked on the side of the rod with a large caliber, and it is locked against the rod with a small caliber. The ends of the rods are inserted into each other to form a staggered nest, making full use of the strength advantages of the rod material itself to bear most of the shearing force generated by the connecting joint, as shown in FIG. 8 and FIG. 9.

(22) The locking mechanism 8 includes a sheath 81 and a handle 82 with a cam part located on the sheath. The sheath 81 is nested on the side of the shaft rod 3 with a large caliber, and the cam portion 83 of the handle 82 can rest on one side of the smaller caliber sunshade pole 301 to form a locking structure between the two. During operation, only one hand is needed to swing the handle 82, which is simple and easy. The other hand is used to hold the sunshade pole 301 and adjust the rotation. Furthermore, the rivet of the locking sheath 81 happens to be used as a limit for inserting the rod, as shown in FIG. 9, thus achieving two goals.

(23) Once the angle of the sunshade 300 is adjusted, the center of gravity of the sunshade will also shift. This results in the instability of the folding table. For this reason, a centering rod 32 is arranged at the upper end of the shaft rod 3 to adjust the center of gravity of the sunshade 300 so that it remains in the central area of the folding table. The centering rod 32 can actually be bent directly from the shaft rod 3. However, it would affect the height of the folding table after being folded, so the separation is more reasonable, and it can bring the benefits of adjusting the position.

(24) As shown in FIGS. 6 and 8, the upper inclined section 31 on the shaft rod 3 is transferred to the centering rod 32 to maintain the straight structure of the shaft rod 3 and does not protrude after being folded, as shown in FIG. 7. More specifically, the centering rod 32 has a lower straight section 321, a curved section 322, and an upper inclined section 31. The upper inclined section 31 of the centering rod 32 and the lower inclined section 303 of the sunshade shaft form a connection. The lower straight section 321 is connected to the upper end of the shaft rod 3, making it equivalent to forming a centering rod from a shaft rod. A locking mechanism 8 is provided at the connecting position, and the orientation of the sunshade rod 301 can be adjusted by the locking mechanism at the lower straight section 321, that is, the orientation of the inclined sunshade surface. More specifically, there are two locking mechanisms 8, one is used to adjust the inclination angle of the sunshade surface, and the other is used to adjust the orientation of the sunshade surface. Each performs its own duty, and there is no need to adjust the position of the folding table to adjust the sunshade orientation.

(25) Furthermore, the shaft rod 3 and the sunshade rod 301 have the same caliber and are smaller than the caliber of the centering rod 32. The ends of the shaft rod 3 and the sunshade rod 301 are inserted into the centering rod 32 when they are connected, and the locking mechanism 8 is locked on one side of the centering rod 32. After disassembly, the two locking mechanisms 8 and the centering rod 32 are short and easy to store. Furthermore, the lower straight section 321 and the upper inclined section 31 of the centering rod 32 can be designed to be rotationally symmetrical. Either end can be selected for assembly, which brings convenience to on-site installation.

(26) Referring now to FIG. 10, the shaft rod 3 and the sunshade pole 301 have an upper inclined section 31 and a lower inclined section 303 with the same inclination angle. The angle X between the upper inclined section 31 and the centerline of the shaft rod 3 is equal to the angle between the lower inclined section 303 and the centerline of the sunshade pole 301. The lower inclined section 303 and the upper inclined section 31 are inserted to keep the center lines of the upper inclined section overlapped with the lower inclined section. The rotation of the lower inclined section 303 drives the sunshade pole 301 to rotate. The sunshade pole 301 will be adjusted in the range of upright to twice the included angle with the vertical line. The solid line in the figure shows that the sunshade pole 301 is in an upright state, and the dotted line indicates that the sunshade pole is at the limit angle of twice the included angle. With this structure, the inclination angle of the sunshade surface can be adjusted within this range. The upward inclined section 31 on the shaft rod points to the direction of the sunshade surface inclination. Pointing to the East blocks the sunlight from the East. For this reason, through the setting of a centering rod 32, an additional function of convenient adjustment of the orientation is achieved.
