Detailed ways

The embodiment of the utility model provides a backrest chair, which is used to solve the technical problems of the existing backrest chairs such as many processing steps, troublesome manufacture, poor strength, poor air permeability and uncomfortable sitting.

In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the utility model embodiment will be clearly and completely described below in conjunction with the accompanying drawings in the utility model embodiment, Apparently, the embodiments described below are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1 to Fig. 3, the embodiment of the utility model provides an embodiment of a chair with a backrest including:

The seat surface 3, the back surface 4 and two side brackets 1, the seat surface 3 is fixed between the two side brackets 1, and the back surface 4 is located between the two side brackets 1. It must be noted that the aforementioned two side brackets 1 is a symmetrical structure design, and further, the two side supports 1 are rectangular or square supports, and the seating surface 3 and the top of the side supports 1 are located on the same horizontal plane. It can be understood that, as shown in Figures 1 to 3, the side supports The top of 1 and the surface of the seating surface 3 are located on the same horizontal plane, and cross bars 2 are fixed between the two legs of the two side supports 1;

In this embodiment, as shown in Fig. 1 to Fig. 3, two side supports 1 are made up of two bamboo slats of 450/20*30 specification and 2 bamboo slats of 360/20*30 specification, wherein The mortise and tenon structure is connected. On two 360/20×30 bamboo slats, there are 4 bolt holes drilled, of which 2 holes are used for the connection of the seat surface 3, and the other 2 holes are used for the back surface 4 connection, and the positions of these two holes also determine that the angle between the seat surface 4 and the seat surface 3 is an obtuse angle.

The rest surface 4 is respectively fixed to the two side supports 1 and the cross bars 2;

The included angle between the seat surface 4 and the seat surface 3 is an obtuse angle.

As shown in Figure 1, the reclining chair can further include:

The back surface 4 includes a backrest 7 and a support mechanism 8, the support mechanism 8 is arranged at the lower end of the backrest 7, and the aforementioned support mechanism 8 is composed of an extension part 81 on the side of the backrest 7 and a transverse rod 6; The transverse bar 6 is arranged between the two extension parts 81 .

It should be noted that, as shown in FIG. 2 , the angle between the plane where the rest surface 4 and the seat surface 3 are located is an obtuse angle. When the plane angle between the back surface 4 and the sitting surface 3 is 105°, the plane angle design between the back surface 4 and the sitting surface 3 conforms to the ergonomic design of the human body. When a person uses the backrest chair, the person's back leans against the backrest 7, the comfort is improved; when the plane angle between the back surface 4 and the sitting surface 3 is 108°, the angle design of the plane between the back surface 4 and the sitting surface 3 conforms to the ergonomic design, and when people use the back chair When the person's back leans against the backrest 7, the comfort is improved. It must be noted that the aforementioned 105° and 108° are only two preferred embodiments. When the plane angle range between the back surface 4 and the sitting surface 3 Between 105° and 108°, all belong to ergonomic design.

As shown in FIG. 4 to FIG. 6 , in this embodiment, the aforementioned seating surface 3 may have two scale modes. The first type consists of 20×30 bamboo slats laid flat and joined by mortise and tenon joints to form a large side frame of the sitting surface, and 10x46 thin slats are embedded in the middle with a mortise and tenon structure. The second type consists of two 20×30 scale slats connected to the side brackets placed vertically, while the other two 20×30 scale slats are laid flat to form a large side frame of the seating surface, and a mortise and tenon structure of 10×58 scale thin plates embedded in the center. Two bolt holes are respectively drilled on the large sides connected with the side brackets on both sides of the seat surface, 75 yards away from the two sides, so that the installation of the seat surface components in various situations is not easy to make mistakes.

It should be noted that, as shown in FIG. 1 , in this embodiment, the aforementioned backrest 7 is composed of a seat 5 and more than two slats. It can be understood that, in other embodiments, the seat surface 3 and the backrest 7 It can be a whole board. The gaps between the slats make the sitting surface 3 and the backrest 7 have good permeability. In addition, the slats have moderate elasticity due to their small enough scale and thickness.

As shown in Fig. 4 to Fig. 6, in this embodiment, the backrest 7 also has two kinds of scale configuration modes, the first one is formed by two 360/20×30 scale large sides and 750/20×30 scale large sides squared to form the backrest 7 The main frame, with a large side of the same size of 300/20×30 placed flat on its upper part forms the frame of the backrest 7, in which 5 pieces of 280/10×46 thin slats are embedded in the mortise and tenon method as the main body of the backrest 7. The lower part drills 4 bolt holes on the large side to connect with the side brackets. The second type consists of two 750/20×30 large sides placed vertically, and the other two 360/20×30 large sides placed flat and embedded into the aforementioned vertically placed large sides by mortise and tenon, and one is added in between The large side of 360/20×30 scale is squarely embedded in the vertical enlarged side to form the frame of backrest 7, and 5 pieces of thin slats of 240/10×58 scale are embedded as the main body of backrest 7 in the way of mortise and tenon. Its lower part then drills 4 bolt holes on the vertical large side to be connected with the side bracket.

It must be noted that the aforementioned sitting surface 3 and the resting surface 4 are made of synthetic bamboo materials.

The R3 fillet treatment of all component elements in the embodiment of the utility model and the R1 fillet treatment around all bolt holes are also key details of the component design of the utility model. These fillet treatments not only eliminate any possible occurrences in the use of bamboo composite materials. The burr phenomenon also makes the whole product image light and comfortable, and the line angle formed by the connection of different components also adds beauty to the product appearance.

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 .
