Description
Technical field
The invention relates to a kind of crutch chair, especially a kind of Labor-saving safety and the crutch chair of folding can be facilitated.
Background technology
For convenience of receiving and keeping and moving, what existing chair had be designed to can the form of folding, especially one has a crutch bar is chair body, and the crutch chair made crutch and use can be served as after folding, its structure is simple, after folding, old man or handicapped people walking can be assisted as crutch simultaneously, quite practical and convenient.
But, existing crutch chair is after folding, after folding, the position of centre of gravity of crutch chair is positioned at close to crutch bar middle position, and user like this is when assisting walking with the crutch chair after folding, because of center of gravity low crutch bar, to swing the moment produced larger, the burden of user can be increased, and when walking, because the chair pin after folding is positioned at below and outside jag, easily and ground article or user self collide, the derivative danger hooking lift-over with tripping and fall, and cause the inconvenience in use.
Summary of the invention
In order to the disappearance solving existing crutch chair structure and use, the invention provides a kind of crutch chair, this crutch chair is after folding, can allow the position of centre of gravity of crutch chair be positioned at crutch bar close to top end, and volume-diminished is concentrated, the object improving crutch chair ease of use and security can be reached.
The present invention is the technical scheme solving the employing of its technical problem: a kind of crutch chair, includes:
One crutch bar, this crutch bar has leader portion, in the stage casing of this crutch bar, middle position is provided with a holder, is provided with one is pivoted seat in crutch bar stage casing between the top of crutch bar and this holder;
One seat support, this seat support and a pivot joint that is pivoted;
One chair pin, this chair pin is articulated in this crutch bar; And
One support bar group, this support bar group is articulated between seat support and chair pin, and after this crutch chair folding, the position of centre of gravity of crutch chair is between the stage casing and top of crutch bar.
By above-mentioned technological means, the present invention drives the upwards folding of chair pin by upwards overturning seat support, and make crutch chair of the present invention position of centre of gravity overall after folding be positioned at the top end of nearly crutch bar, so, user is when using the crutch chair after folding to assist walking, the moment swung is less, comparatively easily laborsaving during swing, the burden of person capable of reducing using, and the seat support after avoiding user and folding and chair pin collide, and it is dangerous to cause that user trips etc., improve convenience and security that crutch chair uses.
