[0021] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0022] See also Figure 1 , Figure 2 and Figure 3 An embodiment of the folding device with sliding and fixing function of the present invention comprises an axle seat 2, three foot rod units 3, three turning rods 4, a pivot unit 5, and a cloth piece 6.

[0023] Each foot rod unit 3 includes a foot rod 31 passing through the shaft seat 2, and a stopper 32 disposed on the foot rod 31. The foot rod 31 has a top section 311 located above the shaft seat 2.

[0024] The limiting member 32 has a fixing portion 321 disposed on the top section 311 and a limiting portion 322 extending upward from the fixing portion 321. The limiting portion 322 and the top section 311 together define an upwardly open receiving groove 33.

[0025] See also Figure 1 , Figure 3 and Figure 4 Each turning rod 4 includes a connecting section 41 adjacent to the top section 311 of the respective foot rod 31, a swinging section 42 opposite to the connecting section 41, a fixed section 43 located between the connecting section 41 and the swinging section 42 and adjacent to the connecting section 41, and two guide grooves 44 arranged opposite to each other on the connecting section 41 and extending along the axial direction of the turning rod 4 itself.

[0026] The pivot unit 5 includes three driving members 51 respectively connected to the fixing sections 43 , and three pivots 52 respectively disposed on the top sections 311 of the foot rod 31 and respectively connected to the driving members 51 and passing through corresponding guide slots 44 .

[0027] Each driving member 51 is disposed between the respective top section 311 and the respective connecting section 41 and constantly applies a driving force to move the top section 311 and the connecting section 41 away from each other. Each driving member 51 has a middle section 511 connected to the respective fixing section 43, and two mounting sections 512 extending downward from the middle section 511 and respectively mounted on the opposite ends of the corresponding pivot 52. In this embodiment, the driving member 51 is a spring, and the mounting section 512 of each driving member 51 is mounted on the opposite ends of the corresponding pivot 52 extending from the corresponding top section 311.

[0028] The fabric piece 6 is connected to the swing section 42 of the turning rod 4 .

[0029] When the turning rod 4 is rotated relative to the foot rod 31 to a position where the turning rod 4 and the foot rod 31 extend in opposite directions, the turning rod 4 can be switched between a restricted position and a disengaged position relative to the foot rod 31 .

[0030] See also Figure 3 , Figure 5 and Figure 6 When in the restricted position, the turning rod 4 is subjected to a downward external force to overcome the driving force of the driving member 51, and the turning rod 4 slides downward (such as Figure 5 , Figure 6 The connecting sections 41 are respectively embedded downward into the bottom of the accommodating groove 33, so that the turning rod 4 is respectively limited by the limiting portion 322 and the top section 311 of the foot rod 31 on two opposite sides and cannot rotate. At this time, the pivot 52 is relatively located at the top of the guide groove 44, and the turning rod 4 is respectively against the top of the pivot 52.

[0031] See also Figure 3 , Figure 7 and Figure 8 When in the disengaged position, the turning rod 4 is no longer subjected to external force, and the driving force of the driving member 51 causes the turning rod 4 to slide upward (such as Figure 7 , Figure 8 ) until the connecting sections 41 are separated from the bottom of the receiving groove 33 upward, so that the turning rod 4 is no longer limited by the limiting portion 32 and can rotate (see Fig. 9At this time, the pivot 52 is relatively located at the bottom of the guide slot 44 , and the turning rods 4 are respectively against the bottom of the pivot 52 .

[0032] See also Figure 1 and Figure 3 When in use, the turning rod 4 is rotated relative to the foot rod 31 to a position where the turning rod 4 extends in the opposite direction to the foot rod 31, and the cloth piece 6 is stretched out by the turning rod 4 to form a plane, so that a user can sit on it. Since the extension length of the turning rod 4 and the size of the cloth piece 6 are larger than the size of the foot rod 31, the user can sit more comfortably.

[0033] See also Figure 1 , Figure 3 and Figure 6 When the user sits on the cloth piece 6, the body gravity will be applied to the cloth piece 6 and the turning rod 4, thereby causing the turning rod 4 to move to the restricted position relative to the foot rod 31, so that the turning rod 4 is limited by the limiting portion 322 and cannot rotate, thereby ensuring that the structure of the folding device with sliding and fixing function is stable and will not shake.

[0034] See also Figure 1 , Figure 3 and Figure 8 When the user stands up and leaves the cloth piece 6, the cloth piece 6 and the turning rod 4 are no longer subjected to force, and the turning rod 4 is driven by the driving force of the driving member 51 and moves to the disengaged position relative to the foot rod 31. The turning rod 4 is no longer limited by the limiting portion 322 and can be easily flipped and folded.

[0035] It should be noted that the present embodiment takes three foot rod units 3, three turning rods 4 and three driving members 51 as an example, but this is not a condition to limit the quantity. When the number of turning rods 4 is one or two, the number of corresponding components can also be adjusted to achieve the same effect.

[0036] In summary, by providing the foot rod 31, the limiting member 32, the turning rod 4 and the driving member 51, the turning rod 4 can be transformed between the limiting position and the disengaged position relative to the foot rod 31, and can be limited after being subjected to force to maintain structural stability, so the purpose of the present invention can be achieved.
