Abstract

A folding chair belongs to furniture, and mainly solves the problem that the folding chair cannot be used as ladder. The folding chair structurally comprises a chair surface, a chair frame and a chair back, wherein a horizontal rotating shaft is arranged at the top part of two sides of the chair frame; the lower part of the chair back is movably connected with the chair frame by the rotating shaft; the middle parts of both sides of the chair frame are provided with an axial groove, respectively; a horizontal rotating shaft is arranged at the upper part of the chair back; a strut is movably connected at the rotating shafts of two sides of the chair back, respectively; the struts are equal in length; and the lower parts of the struts are embedded in the groove on the chair frame of the same side. With the adoption of the structure in which the chair back and the chair frame are connected by a four-connection-rod mechanism, a leaning function is provided when the chair back is folded, a two-step ladder is defined by the chair back and the chair surface when the chair back is unfolded horizontally, and thus the folding chair is convenient for a user to climb.

Description

A kind of folding seat

Technical field

The utility model relates to a kind of furniture, specifically a kind of folding seat.

Background technology

Chair is to be used to provide the furniture that the user takes a load off one's feet, and folding seat is a kind of chair that can stored collapsed, can reduce floor space.But existing folding seat can only provide the function that takes a load off one's feet, and the user usually needs to ascend a height and gets thing in real life, but can not find anywhere or anytime ladder to ascend a height.

The utility model content

The purpose of this utility model is to provide a kind of folding seat, and mainly solving folding seat can't be as the problem of ladder use.

The technical scheme in the invention for solving the technical problem is: a kind of folding seat, its structure comprises seat, chair frame and the chair back, the top of the both sides of described chair frame is provided with the rotating shaft of a level, the bottom of the chair back is flexibly connected by this rotating shaft and chair frame, the middle part of chair frame both sides respectively is provided with an axial groove, the top of the described chair back is provided with the rotating shaft of a level, rotating shaft place of chair back both sides is flexibly connected an isometric pole separately, and the bottom of pole is embedded in the groove on the homonymy chair frame.

The beneficial effects of the utility model are: adopt the structure that the chair back and chair frame are connected by four-bar mechanism, can make the chair back that function of leaning is provided when packing up, the chair back makes things convenient for the user to climb when keeping flat and the common secondary ladder of composition of seat.

Description of drawings

Fig. 1 is structural representation of the present utility model (chair back flat condition).

Among the figure: 1 chair frame, 2 rotating shafts, 3 chair back, 4 rotating shafts, 5 poles, 6 grooves, 7 seats.

The specific embodiment

As shown in Figure 1.A kind of folding seat, its structure comprises seat 7, chair frame 1 and the chair back 3, the top of the both sides of described chair frame 1 is provided with the rotating shaft 2 of a level, the bottom of the chair back 3 is flexibly connected by rotating shaft 2 and chair frame 1, the middle part of chair frame 1 both sides respectively is provided with an axial groove 6, the top of the described chair back 3 is provided with the rotating shaft 4 of a level, and rotating shaft 4 places of the chair back 3 both sides are flexibly connected an isometric pole 5 separately, and the bottom of pole 5 is embedded in the groove 6 on the homonymy chair frame 1.Described pole 5 can be free to slide in groove 6, and when pole 5 was positioned at groove 6 lower end, the chair back 3 was parallel to each other with seat 7.

When taking a load off one's feet, the chair back 3 packed up lean against on the chair frame 1, be sitting in user on the seat 7 and can lean against on the chair back 3 and loosen rest.When needs are ascended a height when getting thing, the chair back 32 can be rotated around the shaft, pole 5 is thereupon along groove 6 down slidings, and when pole 5 slided into the lower end of groove 6, the chair back 3 was parallel to each other with seat 7.At this moment, this folding seat becomes a secondary ladder that is comprised of the chair back 3 and seat 7, and the user can ascend a height by this two stage steps and get thing.
