Abstract

The invention discloses a crutch chair. According to the crutch chair, the middle section close to the middle of a crutch stick is provided with a fixed seat, and the middle section close to the top of the crutch stick is provided with a pivot seat which can move relative to the crutch chair. The crutch chair also comprises a chair seat pivoted to the pivot seat, a chair leg pivoted to the fixed seat, and a support rod set pivoted between the chair seat and the chair leg. When the crutch chair is folded, the center of gravity of the crutch chairs is located between the middle section and the top of the crutch rod. When a user uses the folded crutch chair for walking assisting, the swing moment can be relatively small, forward and backward swinging can be relatively easy and labor-saving, so that the load of the user can be reduced, meanwhile dangers such as stumbling of the user due to collision between the user and the folded chair seat or chair leg, further the usage convenience and safety of the crutch chair can be enhanced.

Description

Crutch chair

Technical field

The present invention is about a kind of crutch chair, especially a kind of Labor-saving safety and can facilitate the crutch chair of folding.

Background technology

For convenience of harvesting and mobile, existing chair have be designed to can folding form, especially to have a crutch bar be chair body to one, and can after folding, serve as and make the crutch chair that crutch uses, it is simple in structure, can after folding, assist old man or handicapped people's walking 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 to be positioned at nearly crutch bar centre position place, and so user is in the time that the crutch chair with after folding is assisted walking, and because of underslung crutch bar, to swing the moment producing larger, can increase user's burden, and when walking, because the seat support pin after folding is positioned at below and outside jag, easy and ground article or user self collision, the danger that the lift-over with tripping of derivative hook is fallen, and cause the inconvenience in use.

Summary of the invention

In order to solve in existing crutch chair structure and the disappearance using, 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 that improves crutch chair ease of use and security.

The present invention adopts technical scheme to be for achieving the above object, and a kind of crutch chair, includes:

One crutch bar, this crutch masthead end forms leader portion, is provided with a holder in crutch bar stage casing near position in the middle;

One seat support group, this seat support group is can be slidably arranged on crutch bar, this seat support group includes a seat that is pivoted that is positioned at crutch bar stage casing, this position of close crutch masthead end can moving relative to crutch bar of being pivoted, and one and a seat support being articulated 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 and be pivoted after seat along crutch bar, allow seat support and the chair pin be all that relative crutch bar moves up or turns down, to be positioned at the top end that approaches crutch bar and make the position of centre of gravity of crutch chair of the present invention entirety after folding, so, when the crutch chair of user after use folds assisted walking, the moment swinging is less, comparatively easily laborsaving when swing, person's capable of reducing using burden, and seat support and chair pin after avoiding user and folding bump, and it is dangerous to cause that user trips etc., improve convenience and security that crutch chair uses.
