Description

A foldable backrest chair

technical field

The invention relates to the field of furniture, in particular to a foldable backrest 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. In particular, due to various reasons, the ancient Chinese seat system did not develop a stackable function, which is not conducive to transportation after mass production, and thus hinders its popularization among ordinary users. This has to be said to be a shortcoming.

An embodiment of the present invention provides a foldable backrest chair, which includes a seat frame, four cross bars, a seat surface, front feet, rear feet, and a backrest. It is characterized in that the distance between the rear feet is greater than the The width of the seat frame, the seat frame is a rectangle; the distance between the four horizontal bars and the seat frame is the same, which is 1.5 to 2.5 times the vertical width of the horizontal bars; A decorative panel is placed in the central part between the horizontal sill, the right sill and the seat frame. The invention improves the simplification of the traditional lamp hanging chair, is easy to mass-produce and manufacture, and can be stacked and transported to save space. On the one hand, the trim board between the cross frame and the seat frame is introduced to form a close support structure with sufficient strength between the trim board, the seat frame and the cross frame by using small components, and at the same time, small pieces of materials are used as much as possible. It minimizes the deformation factor of the material, creates greater permeability for the lower space of the seat, and facilitates cleaning; on the other hand, the distance between the rear feet is greater than the width of the seat frame so that When they are stacked, they can be inserted into the space on both sides of the seat frame, so that they can be stacked together conveniently and save space. And because the distance between the four cross bars and the seat frame is the same, it can maintain relative stability when stacked and dropped, and is easy to transport.

Detailed ways

Referring to Fig. 1 to Fig. 4, the foldable recliner chair provided by the embodiment of the present invention includes: a seat frame 1, a seat surface 2, a front foot 3, a rear foot 4, a backrest 5, and four cross bars 6, wherein, the rear The distance between the feet 4 is greater than the width of the seat frame 1; the distance between the four horizontal bars 6 and the seat frame 1 is the same, which is 1.5 to 2.5 times the vertical width of the horizontal bars; A decorative plate 7 is respectively placed in the central part between the horizontal sill, the right horizontal sill and the seat frame.

Please refer to Fig. 5 and Fig. 6, in this embodiment, the back chair can be stacked as shown. Because the distance between the back feet 4 of the upper chair is greater than the width 1 of the seat frame 1 of the lower floor, it can be inserted into the space on both sides of the seat frame 1 when it is stacked, so that it can be stacked together conveniently. And because the distance between the four cross bars 6 and the seat frame 1 is the same, the relative stability when stacked and dropped can be maintained. There are two types of stacking modes. One is vertical stacking under the normal rotation state of the product. However, this type of stacking mode will cause the center of gravity of the stacked chairs to move forward continuously. The number of chairs should be limited according to the weight parameters during actual production; the second is to stack them vertically in a tilted state, so that the center of gravity of the stacked chairs remains on the same vertical axis, thus forming a theoretically infinite seat. vertical stacking mode.

In this embodiment, the rear feet 4 are fixed on both sides of the rear portion of the seat frame 1 . Therefore, on the basis of realizing the above-mentioned stacking function, keeping the structural compactness of the back chair is not only conducive to optimizing the structural strength, but also maintaining the visual aesthetics.

FIG. 1 contains a schematic illustration of an embodiment of the plaque 7 . In this implementation, there are two cross bars 7, which are respectively installed between the front legs 3 and the rear legs 4, and are all closely attached to and arranged under the seat frame 1. The lateral width of the decorative plate 7 is preferably 20% to 50% of the length of the crossbar. As a decorative element of the supporting structure of the seat surface, this embodiment forms a closely supported structure with sufficient strength between the decorative plate, the seat frame, and the horizontal frame according to the principle of centralized functional decoration in ancient Chinese furniture design, and at the same time, as much as possible Small pieces of material are used to minimize the deformation factor of the material.

FIG. 2 also shows a schematic view of an embodiment of the seating surface 2 . Sitting surface 2 The sitting surface is composed of juxtaposed trough-shaped slats, and there are gaps between these trough-shaped slats as ventilation holes, so that users will not feel stuffy when sitting on it. The small 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 easily deformed. As the seating surface 2, the user is more comfortable to use.

Please refer to Figures 3 and 4, the backrest of the recliner 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.

Please refer to Figures 3 and 4, the folding part of the backrest can be formed by several groove-shaped slats, and there are gaps between these groove-shaped slats as ventilation holes, so that the user will not feel stuffy when leaning on it. 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.

Referring to FIG. 7, another embodiment of the folding portion is provided. 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 mentioned above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it can still understand the foregoing The technical solutions recorded in each embodiment are modified, or some of the technical features are replaced equivalently; 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 invention.
