Chair CN201610191657.X only discloses two folding places of crawler belt accommodating mechanism and handrail handle, and the distinctive chassis of the present invention is recessed
Slot both ends are respectively provided with card slot A and card slot B, so that seat storage is steady, are that the said goods do not have, meanwhile, pull rod is fixed
It is peculiar that hyte part makes pull rod expand convenient and product, also, calculates 75 kilograms of adult, and folding ratio only uses body
Long-pending 1/6th, a kind of electric stairs-mover, CN201610782477.9 and a kind of automatic stari creeping chair
CN201610191657.X is the one third of original folding volume to half.
For similar product: Portable folding type stretcher wheel-chair, application number: CN03267998.X, a kind of multifunctional motor-driven
Stairs-mover CN201510396206.5, simple to rescue stair-climbing wheel chair CN201520056421.6, the said goods are not involved with
The improvement of control box, the improvement of seat frame, the improvement of heel brace frame, the improvement of handrail and the improvement of seat accommodating mechanism, above-mentioned three
A product folding volume does not accomplish the star-wheel mechanism ultimate attainment, simply rescue stair-climbing wheel chair or market are gradually eliminated, Yi Zhongduo
Functional electric stairs-mover can not achieve level walking, only climb building miscellaneous function merely, not have handrail controller, by battery
Power moves ahead, and Portable folding type stretcher wheel-chair does not climb building function, the currently not same industry field, for this purpose, eightfold folds
Eight components of mechanism all have an impact the volume reduction of electric upstairs going chair, squeeze into European & American Market for company and provide guarantee.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content, belongs to abuse.
