The front end of lifting support 1 is provided with roller 11, and the front end of specially left bottom bar 1a and the front end of right bottom bar 1b set respectively
A roller 11 is equipped with, to reduce the frictional force when the second use state is converted to, between lifting support 1 and ground.
As shown in accompanying drawing 1-4, the wheelchair lowering or hoisting gear in the first use state, the basic horizontal of lifting support 1, each
Stepped plate 4 is also horizontal and is spliced into the supporting surface of a basic horizontal successively, wheelchair can be carried out to supporting surface, so
Afterwards front driving mechanism 6a and rear drive mechanism 6b synchronization actions make the synchronous lifting of the outer bar 61 of each expansion link, left and right handrail 3b and
Lifting support 1 is synchronous to be lifted, and to the position fair with plateau is reached, wheelchair easily can be implemented in plateau, otherwise also
So, where being easy to wheelchair user higher up and down, convenient use.
When need not using for wheelchair, wheelchair lowering or hoisting gear is switched to into the second use state, it is possible to use
Make common step stair, use up and down for normal person.Handoff procedure is as follows：Two front driving mechanism 6a synchronization actions or two
Individual rear drive mechanism 6b synchronization actions make the front end of lifting support 1 and handrail 3 relatively low（Roller 11 is kept to support on the ground
State）And rear end is higher（Extremely maintain an equal level or slightly lower with plateau）, now lifting support 1 and handrail 3 be all from A-P gradually to
Upper inclined state, under the drawing of side connector 2, each stepped plate remains in that level, as lifting support 1 is with handrail 3
Inclination, present step-like distribution naturally, latter stepped plate 4 is higher than previous stepped plate 4, as depicted in figures 5 and 6.Constitute
Stair with multiple steps；And avoid wheelchair and needed the process of lowering or hoisting gear stored collapsed using rear, using more
It is convenient.
Above-described embodiment technology design only to illustrate the invention and feature, are a kind of preferred embodiments, and its purpose exists
In allowing person skilled in the art to will appreciate that present disclosure and implementing according to this, guarantor of the invention can not be limited with this
Shield scope.Equivalence changes or modification that all spirit of the invention are made, all should cover in protection scope of the present invention
Within.
