Below the embodiment accompanying drawing is explained:

Fig. 1 embodiment schematic appearance;

Side view when Fig. 2 embodiment is folding;

Front view when Fig. 3 embodiment is folding.

Indicate among the figure: 1. backrest; 2. backboard; 3. campstool face; 4. handle; 5. front-wheel support bar; 6. foot support; 7. be with the base plate of universal wheel; 8. campstool support; 9. wheel; 10. cross-arm; 11. nylon rope; 12. backrest support rods.

Backrest 1 and backrest support rods 12 are the two ends that are connected to two cross-arms 10 (these two cross-arms wrap in the campstool face in Fig. 1, can't see) above the campstool, and rotatable.Stretch to front curve the both sides of backrest 1, therefore has the function of handrail concurrently.Backrest support rods 12 has two, and its upper end is connected to the left and right sides of backrest 1, and rotatable.A backboard 2 is housed at the rear of backrest 1, and its top has two points to be connected with backrest 1; Also there are two points in its bottom, is connected with the cross-arm two ends at rear above the campstool.The main effect of backboard 2 is to make backrest firm.

Wheel 9 respectively is equipped with at the two ends of the rear cross-arm below the campstool.The base plate 7 of band universal wheel is triangular in shape, and a universal wheel is respectively arranged on three angles, is in ground, campstool the place ahead during use.Its front portion upwards is connected with the cross-arm in the place ahead, campstool top by front-wheel support bar 5, and junction point is all rotatable up and down.Its middle part cross-arm in the place ahead below campstool is connected, and rotatable.This cross-arm is shorter, does not have the part that outwards stretches; Two foot supports 6 also are equipped with in its middle part.The time spent upwards is not attached to the inboard of campstool support 8 to foot support 6; Overturn forward during use be pressed in the band universal wheel base plate 7 above.When foot support 6 upwards was attached to campstool support inboard, the people was sitting on the campstool bipod and can steps on ground and walk.

Why the base plate of backrest and band universal wheel can fold at first thereupon when campstool is folding, and two cross-arms above the campstool do not align when campstool is folding, but the height of front a bit, the hanging down a bit of back; Simultaneously, the length of backrest support rods than backrest and backrest support rods junction point to and the junction point of cross-arm between distance short, so backrest support rods can haul backrest and rolls over backward automatically when campstool folds.On the other hand, when campstool was folding, elongated the campstool front portion distance between two cross-arms up and down, and at this moment the angle between the base plate of front-wheel support bar and band universal wheel will be widened, until being straightened, so be with the base plate of universal wheel promptly to be affixed to the one side of campstool.
