[0029] The present invention is described in detail below with reference to the accompanying drawings and embodiments.
[0030] For the convenience of description, in the following embodiments, the same elements are denoted by the same reference numerals.
[0031] See also Figure 1 , Figure 2 and Figure 3 The first embodiment of the folding device with a turning rod of the present invention comprises an axle seat 2, three foot rods 3, a pivot unit 4, three turning rods 5, and a fabric piece 6.
[0032] The foot rod 3 passes through the shaft seat 2 , and each foot rod 3 includes a top section 31 located above the shaft seat 2 .
[0033] The foot bar 3 can be transformed between a folded position and a supporting position relative to the shaft seat 2. Figure 1 , 2 In the folded position, the top sections 31 are close to each other, see Figure 3 In the propped-up position, the top sections 31 are away from each other, and the foot bars 3 are staggered and tilted with each other.
[0034] See also Figure 3 , Figure 4 and Figure 5 The pivot unit 4 includes a pivot member 41 located above the shaft seat 2 and three connecting rods 42 pivotally connected to the pivot member 41 .
[0035] See also Figure 3 , Figure 5 and Figure 6 Each connecting rod 42 has a pivoting section 421 pivoted on the pivoting member 41, and a movable section 422 opposite to the pivoting section 421. The movable section 422 has a swing pivot shaft 423. In this embodiment, the extending direction from the pivoting section 421 to the movable section 422 is perpendicular to the extending direction of the swing pivot shaft 423.
[0036] The turning rods 5 are respectively pivoted to the foot rods 3 and are respectively provided for sliding movement of the swing pivot shafts 423 of the movable sections 422. Each turning rod 5 includes a connecting section 51 pivoted to the corresponding top section 31, a swing section 52 opposite to the connecting section 51, and a swing side groove 53 located at the swing section 52 for the corresponding swing pivot shaft 423 to pass through. The connecting section 51 of each turning rod 5 has a pivot 511 provided at the corresponding top section 31 of the foot rod 3, and a retaining wall 512 provided at the pivot 511 and covering a portion of the top section 31. The swing pivot shafts 423 can move along the swing side grooves 53 respectively. In this embodiment, each turning rod 5 is U-shaped.
[0037] Each turning rod 5 can be switched between an unextended position and an extended position relative to the corresponding foot rod 3 .
[0038] See also Figure 2 , Figure 4 and Figure 5 When in the unextended position, the foot rod 3 changes to the retracted position relative to the axle seat 2, and the swing section 52 of the turning rod 5 swings downward to be adjacent to the axle seat 2, so that the corresponding connecting rod 42 is linked with the turning rod 5 and abuts against the turning rod 5, and the corresponding active section 422 of the connecting rod 42 is adjacent to the swing section 52, and the corresponding top section 31 is partially received in the turning rod 5.
[0039] See also Figure 3 and Figure 5 When in the extended position, the foot rod 3 changes to the supporting position relative to the shaft seat 2, and the swinging section 52 of the turning rod 5 swings upward until the connecting section 51 abuts against the corresponding blocking wall 512, restricting the turning rod 5 to stop swinging, and restricting the swinging section 52 and the corresponding foot rod 3 to extend in the opposite direction, and the corresponding movable section 422 of the connecting rod 42 is away from the swinging section 52, and the corresponding connecting rod 42 is horizontally connected to the pivot member 41. The process of the swinging section 52 of the turning rod 5 swinging upward is described in detail in detail. Figure 2 , Figure 7 , Figure 8 and Figure 3 .
[0040] See also Figure 3 and Fig. 9 The fabric piece 6 is connected to the swing section 52 of the turning rod 5 .
[0041] See also Figure 2 , Figure 3 and Fig. 9When the folding chair is to be used, the foot bar 3 of the folding device with a turning rod is adjusted from the folded position to the supporting position relative to the axle seat 2, and each turning rod 5 is flipped upward from the unextended position to the extended position relative to the corresponding foot bar 3, and the cloth piece 6 will be stretched out by the swing section 52 to form a plane for sitting. Since the turning rod 5 can extend the length of the foot bar 3, the area and height of the plane formed by the cloth piece 6 will be larger and higher than the size of the existing folding chair, which is more convenient for users to use.
[0042] It should be noted that the folding device with the turning rod can be applied to not only folding chairs but also folding tables, but is not limited thereto.
[0043] See also Fig.10 and Fig.11 A second embodiment of the present invention is similar to the first embodiment, except that:
[0044] The second embodiment comprises two turning rods 5 respectively pivotally connected to two of the foot rods 3 .
[0045] The foot rod 3 not connected to the turning rod 5 also has a foot rod side groove 32 located corresponding to the top section 31, and the movable section 422 of the connecting rod 42 not connected to the turning rod 5 has a foot pivot shaft 424 that penetrates and can move along the foot rod side groove 32.
[0046] The fabric piece 6 is connected to the swing section 52 of the turning rod 5 and the top section 31 of the foot rod 3 which is not connected to the turning rod 5 .
[0047] When each turning rod 5 is flipped upward from the unextended position to the extended position relative to the corresponding foot rod 3, the cloth piece 6 will be stretched open by the swing section 52 and the top section 31 of the foot rod 3 not connected to the turning rod 5 to form an inclined surface, which can also be used for sitting.
[0048] In this way, the second embodiment can also achieve the same purpose and beneficial effects as the first embodiment.
[0049] See also Fig.12 and Fig.13 The third embodiment of the present invention is similar to the second embodiment, and the difference is that:
[0050] The third embodiment comprises a pivot rod 5 pivotally connected to one of the foot rods 3 .
[0051] The two foot rods 3 not connected to the turning rod 5 also have a foot rod side groove 32 located at the corresponding top section 31, and the movable sections 422 of the two connecting rods 42 not connected to the turning rod 5 respectively have a foot pivot shaft 424 that passes through and can move along the corresponding foot rod side groove 32.
[0052] The fabric piece 6 is connected to the swing section 52 of the turning rod 5 and the top sections 31 of the two foot rods 3 that are not connected to the turning rod 5 .
[0053] When the turning rod 5 is flipped upward from the unextended position to the extended position relative to the corresponding foot rod 3, the cloth piece 6 will be stretched open by the swing section 52 and the top sections 31 of the two foot rods 3 not connected to the turning rod 5 to form an inclined surface, which can also be used for sitting.
[0054] In this way, the third embodiment can also achieve the same purpose and beneficial effects as the second embodiment.
[0055] See also Fig.14 and Fig.15 The fourth embodiment of the present invention is similar to the third embodiment, and the difference is that:
[0056] The pivot unit 4 includes the pivot member 41 and a connecting rod 42 pivotally connected to the pivot member 41 .
[0057] The pivot member 41 extends upward from the shaft seat 2 , and the connecting rod 42 is pivotally connected to the top of the pivot member 41 .
[0058] The two foot bars 3 not connected to the turning bar 5 cancel the foot bar side groove 32 (see Fig.12 ).
[0059] In this way, the fourth embodiment can also achieve the same purpose and beneficial effects as the third embodiment.
[0060] In summary, by pivoting the at least one turning rod 5 to one of the foot rods 3, the overall size can be extended when the at least one turning rod 5 is rotated to the extended position to facilitate the use of the user, thereby achieving the purpose of the present invention.
