Description
Technical field
This utility model relates to a kind of Foldable type wheel chair structure, refers in particular in the side frames of wheelchair upon deployment, can be by auxiliary support frame fixing side frames really, to promote the steadiness of wheelchair.
Background technology
For wheelchair being convenient for carrying and collecting, some wheelchair is designed to folding by its structure.Before relevant, case is if any TaiWan, China patent number 348519 " foldable wheel chair frame ", M265030 " the chair frame structure of Foldable type wheel chair ", 323513 " adjustable wheelchair cross support bar structures ", mainly include a pair of bogie side frame and and fold assembly, wherein, aforementioned side frames comprises one and up vertically extends to form a straight-bar and a hand push portion being formed by straight-bar bending, can between two straight-bars, set up the backrest of a cloth matter whereby, this folds two poles that assembly is pivot joint intersected with each other, and connect respectively aforementioned bogie side frame, for aforementioned side frames, relatively fold or launch.
But above-mentioned front case still has not enough place to have much room for improvement, and main cause is:
1. the bogie side frame due to wheelchair is the structure that can relatively fold, launch, therefore the relatively fixed wheelchair of structure more built on the sand, it between the straight-bar of both sides bogie side frame and hand push portion, is particularly the convenience that folds, launches, the backrest of cloth matter is only set, and the situation that therefore especially easily has built on the sand, rocks produces.
2. because Foldable type wheel chair need be taken the convenience folding into account, therefore also cannot not provide the headrest of user head and neck support, and have the problem that product comfort is comparatively not enough.
For the comparatively not enough problem of comfortableness, there is at present dealer to research and develop as TaiWan, China patent number M323893 " headrest features of wheelchair ", with the both sides of a main support, establish a pair of length-adjustable armed lever, a holder is established in the lower end of this armed lever, to be fixed on the handle of a wheelchair; The central authorities of this main support establish a pillow bar group, and this pillow bar group connects a headrest, and this pillow bar group makes this headrest can adjust up and down height, and adjust position with respect to the fore-and-aft direction of wheelchair, to make the certain rest of headrest in wheelchair user's head and cervical region.
Though but case can be by the main support with pillow bar group is fixedly installed on the bogie side frame of wheelchair before this, so that the function of head and neck support to be provided, because the armed lever of main support is movable, therefore the steadiness for Wheelchair structure there is no help.
In view of this, the design people is for not attaining perfect caused many disappearances and inconvenience in the design of above-mentioned Wheelchair structure, and deeply design, and active research improvement has a fling at and development and Design goes out this case.
Utility model content
