The invention discloses a kind of crutch chair, this crutch chair is, in a crutch bar stage casing, position in the middle is provided with a holder, being provided with one near the position on top in crutch bar stage casing can relative to the seat that is pivoted of crutch bar movement, separately be provided with a seat support be articulated with this seat that is pivoted, a chair pin being pivoted to this holder, and a support bar group be articulated between seat support group 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.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.
Description
Technical field
The present invention about 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, existing chair has that 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 nearly crutch bar middle position, and user like this is when assisting walking with the crutch chair after folding, because of underslung crutch bar, to swing the moment produced larger, the burden of user can be increased, and when walking, because the seat support 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 solve the disappearance in existing crutch chair structure and use, the invention provides a kind of crutch chair, after this crutch chair folding, the position of centre of gravity of crutch chair is positioned at the proximal portion of crutch bar, and volume-diminished is concentrated, reach the object improving crutch chair ease of use and security.
The present invention adopts technical scheme to be that a kind of crutch chair, includes for achieving the above object:
One crutch bar, this crutch masthead end forms leader portion, in crutch bar stage casing, position in the middle is provided with a holder;
One seat support group, this seat support group to be slidably arranged on crutch bar, this seat support group includes the seat that is pivoted that is positioned at crutch bar stage casing, and this seat that is pivoted can move relative to crutch bar near the position of crutch masthead end, and one and the seat support that is articulated of the seat that is pivoted;
One chair pin, this chair pin is pivoted to this holder; And
One support bar group, this support bar group is articulated between seat support group 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 can move up along crutch bar and be pivoted after seat, seat support and chair pin is allowed to be all that relative crutch bar moves up or turns down, and the position of centre of gravity making crutch chair of the present invention overall after folding is positioned at the top end close to 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 the security of crutch chair use.
