Description

A new type of back chair

technical field

The utility model relates to the field of furniture, in particular to a novel back chair.

Background technique

In China, chairs are a part of people's lives, and chairs with backrests occupy an extremely important position. The unified stele chair among the back chairs in the ancient Chinese seating system pays attention to decoration and ceremony, so it has to sacrifice the factors of ergonomics and function in the seat design. Another common traditional style of back chair is the lamp hanging chair. The chair surface is generally square, with an arched backrest and a footrest under the seat surface. The shape feature of the back chair is that the backrest has no armrests, and the two ends of the backrest extend a section.

Light hanging chairs pay more attention to ergonomics, but their structure is still too complicated and simple. On the one hand, it leads to a large and complicated manufacturing workload. On the other hand, it is incompatible with modern mainstream design styles and is difficult to be popular with ordinary users.

Utility model content

The embodiment of the utility model provides a new type of backrest chair, which includes a seat frame, a seat surface, front legs, rear legs, and a backrest. It is characterized in that the seat surface is installed in the seat frame; The back chair also has a front crosspiece, the front crosspiece is located under the seat frame, and the distance from the seat frame is not more than twice the width of the front crosspiece; the backrest chair also has a left crosspiece and a right crosspiece , the left horizontal pipe and the right horizontal pipe are connected with the seat frame by an inverted herringbone diagonal pipe.

Preferably, the seating surface is composed of juxtaposed grooved slats.

Preferably, the seat surface is made of synthetic bamboo material.

Preferably, the outer edge of the backrest of the chair is integrally formed by the upward extension of the two rear legs.

Preferably, the upper part of the backrest has a folding part.

Preferably, the length of the folding portion of the backrest is between 20% and 50% of the height of the backrest.

Preferably, a rectangular board is embedded in the center of the folding part of the backrest.

Preferably, the folding part of the backrest is composed of several grooved slats.

The backrest chair provided by the embodiment of the utility model includes a seat frame, a seat surface, front legs, rear legs, and a backrest. It is characterized in that the seat surface is installed in the seat frame; It has a front crossbar, the front crossbar is located under the seat frame, and the distance from the seat frame is not more than twice the width of the front crossbar; the chair also has a left crossbar and a right crossbar, the The left horizontal pipe and the right horizontal pipe are connected with the seat frame by an inverted herringbone diagonal pipe. The utility model improves the simplification of the traditional lamp hanging chair, and is easy to mass-produce and manufacture. On the one hand, an inverted herringbone cross between the cross and the seat frame is introduced to maintain its overall stability by using the principle of triangular stability, and to create greater permeability for the lower space of the seat, which is also convenient Cleaning work; on the other hand, the ergonomic design is introduced to the backrest part to decompose the weight supported by the back of the human body. This makes the chair more light and easy to use as a whole, and is more in line with the principles of ecological design.

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description These are only some embodiments of the present utility model, and those skilled in the art can also obtain other drawings according to these drawings without any creative effort.

Fig. 1 is a schematic structural view of an embodiment of a new type of chair with a backrest in the embodiment of the utility model;

Fig. 2 is the top view of Fig. 1;

Fig. 3 is a side view of Fig. 1;

Fig. 4 is a front view of Fig. 1 .

Detailed ways

Please refer to Fig. 1 to Fig. 4, the embodiment of the utility model provides a new type of backrest chair, including a seat surface frame 1, a seat surface 2, a front foot 3, a rear foot 4, a backrest 5, and the seat surface 2 is installed on the seat surface frame 1 Inside, the front cross frame 6 is located under the seat frame, and the distance from the seat frame is not greater than twice its vertical thickness. The two side cross bars 7 are placed under the two sides of the seat frame 1, placed between the front foot 3 and the rear foot 4, and connected with the seat frame 1 by an inverted herringbone slant.

In this embodiment, the front crossbar is used to be close to the seat frame, and the smaller distance provides the greatest room for the space for the lower legs and feet to stay. The side frames of the left and right toilets are separated from the seat frame by a certain distance, and the inverted herringbone slant between them is connected by the principle of triangular stability to achieve super stable structural strength.

A schematic diagram of an embodiment of a seating surface 2 is simultaneously shown in FIG. 1 and FIG. 2 . Sitting surface 2 The sitting surface is composed of juxtaposed trough-shaped slats, and gaps are left between these trough-shaped slats as ventilation holes, so that users will not feel stuffy when sitting on it. The trough-shaped slats constituting the sitting surface can be made of several synthetic bamboo boards of the same size. The synthetic bamboo board itself has the characteristics of strong stability, simplicity and beauty, and is not easy to deform. As the seating surface 2, the user is more comfortable to use.

The backrest of the reclining chair in this embodiment is formed by the upward extension of the two rear legs to form its outer edge, thereby ensuring that the backrest has sufficient structural strength and safety. In this embodiment, the upper part of the backrest has a lifting and folding part, which decomposes the weight of the back of the human body. The length of the folding part is between 20% and 50% of the height of the backrest. This length ratio is suitable for users to sit in a normal sitting posture in a relaxed state, bringing users a relaxed and comfortable experience.

In this embodiment, a rectangular plate is embedded in the center of the folded part. According to the principle of centralized functional decoration in ancient Chinese furniture design, the decorative plate, the seat frame and the horizontal frame form a close support structure with sufficient strength. , and at the same time use small pieces of material as much as possible to minimize the deformation factor of the material.

As another embodiment, the folding part of the backrest can be composed of several groove-shaped slats. There are gaps between these grooved slats as ventilation holes, so that users will not feel stuffy when leaning on them. The trough-shaped slats that make up the seat surface can use several synthetic bamboo boards of the same size. The synthetic bamboo board itself has the characteristics of strong stability, simplicity and beauty, and is not easy to deform. It is more comfortable for users to use as the folding part of the backrest.

As mentioned above, the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it still can Modifications are made to the technical solutions described in the foregoing embodiments, or equivalent replacements are made to some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model .
