In the past, transport chairs (also known as wheelchairs) were inconvenient to use due to their large volume when they needed to be carried or stored. Therefore, a foldable transport chair can solve the above problems.

Referring to Fig. 1 and Fig. 2, this kind of transportation chair 1 comprises four vertical vertical pipes 11 parallel to each other, four pairs of pivot joints 12 installed on each vertical pipe 11, four pairs of cross pivot joints and respectively A coupling rod 13 pivotally connected to the pivot joint member 12 on the adjacent standpipe 11, and two handrails 14 made of soft material such as canvas with both ends fixed on every two standpipes 11. The pivoting member 12 includes an upper ring seat 121 and a lower ring seat 122 respectively.

When the transport chair 1 is to be folded, the upper ring seat 121 of the pivot joint 12 slides upward along the standpipe 11 by applying pressure from the left, right and front to the rear, and at the same time the coupling rod 13 is folded together, and the folding is completed Then the standpipes 11 are close to each other, and the armrests 14 are folded and stored between the standpipes 11 .

By virtue of the way in which the pivoting member 12 drives the connecting rod 13 to fold, a certain length of standpipe 11 is required for the pivoting member 12 to move up and down. It is further explained that the length of the standpipe 11 of this kind of transport chair 1 is fixed, and the two ends of the armrest 14 are fixedly connected to every two standpipes 11, so that the armrest 14 must be made of soft material. The transport chair 1 can be folded.

From the above, it can be known that this kind of foldable transport chair 1 must be equipped with armrests 14 made of soft materials, but the support force of the armrests 14 will be insufficient, reducing the comfort of use, and when the user changes posture between sitting and standing , it will be difficult to keep stable due to the insufficient supporting force of the armrest 14, which will increase the inconvenience and danger of use.

【Detailed ways】

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:

Referring to Fig. 3 and Fig. 4, a preferred embodiment of the simple transport chair of the present invention includes a riser unit 2, four pairs of pivot joints 3, four pairs of connecting rods 4, four wheels 5, a seat cover 6, Two handles 7, two handrails 8, and two lifting straps 9.

The standpipe unit 2 includes two short standpipes 21 vertically parallel to each other, and two long standpipes 22 relatively located behind the short standpipes 21 .

Each short riser 21 includes a hollow lower tube portion 211 with a wider diameter, and an upper tube portion 212 telescopically inserted and sleeved in the lower tube portion 211 .

Each pair of pivoting members 3 includes an upper ring seat 31 and a lower ring seat 32 mounted on each of the short standpipes 21 and the long standpipes 22 .

Each of the upper ring base 31 and the lower ring base 32 has two vertically spaced ear portions 311 , 312 respectively.

Wherein two pairs of pivot joint parts 3 upper ring seat 31 and lower ring seat 32 located in each short standpipe 21 are respectively fixed on each lower tube part 211 and upper tube part 212, and said upper ring seat 31 has a A perforation 312 for detachably clamping the armrest 8 .

The other two pairs of upper ring seats 31 of the pivoting member 3 located on each long standpipe 22 are displaceably threaded on each long standpipe 22 .

Each pair of connecting rods 4 is pivotally connected to each other, and pivotally connected to the ears 311 , 312 of each pair of pivoting members 3 on the adjacent short standpipe 21 and long standpipe 22 respectively.
