Wheel apparatus 10 and rear-wheel device 11 will move the most round about.
In quadric chain BCEG, while pin joint C moves along F3 direction, gradually to pin joint G
Draw close.Front rod 5 rotates counterclockwise around pin joint E, now in quadric chain GIHE, and pin joint
H on front rod 5, front rod 5 when pin joint E rotates counterclockwise, pin joint H and pin joint G two
Point distance gradually shortens, and the distance of pin joint I and pin joint E 2 will become larger.Now, whole
Individual vehicle frame will slowly open.
Continue to power F3, vehicle frame is opened to position shown in Fig. 8.Continue to apply in the first bar segment 1
Power F4 (power F4 is contrary with the process of power F1), the first bar segment 1 can rotate counterclockwise to figure around pin joint A
1 (incorporated by reference to reference to Fig. 8 and Fig. 1) position locks (it should be noted that power F4 is the most only it
In the display of a moment, the direction of power F4 changes along with the rotation of the first bar segment 1, and power
The size of F4 can also change constantly), the now gear locking between the second bar segment 2 and back link 3
Device also can lock automatically, stops the operating of linkage, completes vehicle frame opening procedure.Now, whole
Described foldable pushchair recovers to the stable deployed condition shown in Fig. 1.
During above-mentioned expansion, the position that can fix front wheel device 10 is motionless, and other structure is transported
Dynamic, it is also possible to the position of fixing rear-wheel device 11 is motionless, and the carrying out of other structure moves, it is also possible to not solid
Fixed any position, whole foldable pushchair launches.
