Description
Technical field
The present invention is a kind of combined multifunctional move-assistant device, by at middle low age old people and hypodynamia or be in the old people's in rehabilitation stage special requirement, and the innovation of the novel trip instrument that carries out design, by three big functions of simple combination, adjusting realization this combined multifunctional move-assistant device walk help, implementation and electric walk instead.
Background technology
The old industry of China is also very undeveloped at present, and whole blank begins to show but slower development.The elderly population of China, in different regions, aspects such as all ages and classes, different sexes, different health status all exist very big diversity, these differences have objectively caused the complicated and diversified characteristics that old produce market had just.The old product-feed of China docks obviously not enough with old consumer, the articles for use kind is too single, the technological element of a product is lower again.The demand that the present situation in old articles for use market also can not satisfy in modern society life of old people, study, amusement far away, take exercises.Development is fit to diverse in function that the old people uses, simple in structure, combined and instant, the comfortable novel combination type multifunctional move-assistant device of operation to be become inevitable.
Summary of the invention
The objective of the invention is to defective at the prior art existence, towards middle low age old people and hypodynamia or be in the old people in rehabilitation stage, provide a kind of multiple functional, take into full account the partes corporis humani and divide main yardstick, be applicable to that the old people goes out at ordinary times, takes a walk and the combined multifunctional move-assistant device of the various situations of going hiking.Realize three big functions of implementation, walk help and electric walk instead by simple combination, adjusting.
For achieving the above object, design of the present invention is:
The present invention realizes the rotation of handgrip at vertical plane by the angle of regulating the handgrip support bar, fully take into account human body actual size and interactive means, and calculate according to the usage space of design and the overall dimensions of car body, the handgrip support bar anglec of rotation is fixed between-55 ° to+55 °, be set to-55 ° respectively as Fig. 2 ,+15 ° and+55 ° of third gear (to be positive direction clockwise).
When the present invention went to-55 degree shelves when handgrip support bar drive handgrip, apparatus for ride instead of walk was in the user mode that implementation is ridden instead of walk, realizes the function of combined multifunctional move-assistant device implementation.This state is that handicapped person uses design, and occupation mode is same as common wheelchair and go-cart, and user is seated on the medicated cushion, both feet are placed in the step, and other people hold handgrip and promote apparatus for ride instead of walk and advance and control car and turn to.At this moment, two deflecting rollers allow Vehicular turn, promote the vehicle person vehicle drive force is provided, and illustrate as Fig. 3.This state can take off going up the driving device case, to alleviate the apparatus for ride instead of walk overall weight.
The present invention goes to when the handgrip support bar drives handgrip+during 15 degree shelves, with medicated cushion dig, step packs up, apparatus for ride instead of walk is in the user mode that walk help is ridden instead of walk, realizes the function of combined multifunctional move-assistant device walk help.This state is that riding instead of walk of rehabilitation stage used design, and function is same as traditional rehabilitation walk help instrument, and user can the both arms bending, holds the handgrip body support and control car to turn to, and moves paces, advances forward.At this moment, two deflecting rollers allow Vehicular turn, and the walking user provides vehicle drive force, illustrates as Fig. 4.This state can take off going up the driving device case, to alleviate the apparatus for ride instead of walk overall weight.
The present invention goes to when the handgrip support bar drives handgrip+and during 55 degree shelves, apparatus for ride instead of walk is in the user mode of electric walk instead, realizes the function of combined multifunctional move-assistant device electric walk instead.The people is sitting on the medicated cushion, and both feet are placed in the step, and both hands are held handgrip, control car and turn to.At this moment, two deflecting rollers allow Vehicular turn, and driving device provides vehicle drive force, illustrates as Fig. 5.
Combined method of the present invention is simple, diverse in function and easily regulate operation, and the user of service can pass through simple combination, regulate the conversion of independent realization implementation, walk help and electric walk instead function.
According to the foregoing invention design, the present invention adopts following technical proposals:
A kind of combined multifunctional move-assistant device, comprise a vehicle frame, a bogie, a door shape front fork, two handgrips, a medicated cushion, two step support bars, two pedal strokes, two steps, two deflecting rollers, a driving wheel and a driving device case, it is characterized in that:
