Description

new folding chair

technical field

The utility model relates to the field of daily life furniture articles, in particular to a novel folding chair capable of various deformations.

Background technique

Most of the folding chairs currently on the market have a single function, and most of their design concepts are based on "sitting". Therefore, although various chairs have different appearances, their functions are similar, and because of weight considerations, lighter ones Generally all focus on its mobility, while ignoring its comfort and functionality. On the contrary, the slightly heavier one seriously affects its mobility.

At the same time, given that the current supply of sleeper berths on trains is seriously greater than the supply, many people cannot buy sleeper berths. Therefore, passengers who buy long-distance tickets must keep a sitting position during the ride and cannot sleep on their stomachs. Difficult.

Therefore, it is necessary to design a chair-like product, which can not only perform basic functions such as sitting or lying down, but also has mobility and flexibility, and can help passengers who cannot buy sleeper berths.

Contents of the invention

The technical problem to be solved by the utility model is to provide a folding chair that not only solves the problems of weight, function and comfort, but also extends some functions that were not available in the market before, and can adapt to different occasions. New folding chair.

The technical scheme that the utility model solves its technical problem adopts is:

A new type of folding chair, including a backrest, chair legs and a seat cushion, is characterized in that: the backrest, chair legs and seat cushion are all hinged on the same main shaft and can rotate freely to form a three-hinge structure; wherein the chair The bottom of the leg is equipped with a horizontal chair leg support; the backrest can be rotated downward around the main shaft to connect with the chair leg support to form a triangular stable structure composed of the backrest, chair leg and chair leg support; the top of the backrest A reversible pallet is also hinged.

In the above solution, the cushion is a rectangular frame structure, and the two sides of the cushion are telescopic rod structures, which can be extended and folded along the direction perpendicular to the hinged main shaft.

In the above solution, the backrest also has a rectangular frame structure, and the outer dimension of the backrest is larger than that of the seat cushion.

In the above solution, the supporting plate is also a rectangular frame structure, and the bottom edge of the supporting plate is hinged on the top of the backrest.

In the above solution, both sides of the supporting plate are also telescopic rod structures, and the extension direction of the two sides is to extend outward toward the bottom edge of the supporting plate, and form a flat plate structure hinged at the top of the backrest with the middle part after the extension.

The beneficial effects of the utility model are:

The folding chair of the utility model has a simple structure and is easy to carry, not only can perform basic functions such as sitting or lying down, but also has mobility and flexibility, can help passengers who cannot buy sleeping berths, and can adapt to different occasions.

Detailed ways

Below in conjunction with specific embodiment, the utility model is further described:

The novel folding chair shown in Fig. 1 Fig. 2 Fig. 3 Fig. 4 comprises backrest 1, chair leg 2 and cushion 3, and described backrest 1, chair leg 2 and cushion 3 are all hinged on the same main shaft, and can Rotate freely to form a three-hinge structure; wherein the bottom of the chair leg 2 is equipped with a horizontal leg support 5; the backrest 1 can be rotated downward around the main shaft to connect with the leg support 5 to form a backrest 1, The triangular stable structure formed by the chair legs 2 and the chair leg supports 5; the top of the backrest 1 is also hinged with a reversible supporting plate 4.

In this embodiment, the seat cushion 3 is a rectangular frame structure, and the two sides of the seat cushion 3 are telescopic rod structures, which can be extended and folded along the direction perpendicular to the hinged main axis.

In this embodiment, the backrest 1 is also a rectangular frame structure, and the outer dimension of the backrest 1 is larger than that of the seat cushion 3 .

In this embodiment, the supporting plate 4 is also a rectangular frame structure, and the bottom edge of the supporting plate 4 is hinged on the top of the backrest 1 .

In this embodiment, the two sides of the supporting plate 4 are also telescopic rod structures, and the extension direction of the two sides is to extend outward toward the bottom edge of the supporting plate 4, and form a flat plate structure hinged at the top of the backrest 1 after the extension. .

When the utility model is used, the following functions can be produced through deformation:

Sitting (with backrest): As shown in Figure 1 and Figure 2, this function is no different from that of ordinary folding chairs. All are to meet the most basic sitting function of the chair. However, in order to meet its comfort requirements, as shown in Figure 2, there is also a backrest on the basis of sitting, which not only meets the comfort, but also can be used depending on the size of the surrounding environment space, and has more flexibility.

Lying: as shown in Figure 3, chairs with this function also appear in the market, such as general beach chairs have the function of lying. But in comparison, the utility model embodiment has more advantages in terms of flexibility and maneuverability.

Lying: As shown in Figure 4, none of the folding chairs in the current market have this function. When this function is used, it can not only be used as a simple table, but also seem to be able to sleep on it when you are tired.

The above descriptions are only application examples of the utility model, and of course the scope of rights of the utility model cannot be limited with this. Therefore, equivalent changes made according to the patent scope of the utility model still belong to the protection scope of the utility model.
