Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a back support body and a chair back. Background Art

[0002] Chairs are one of the most common furniture in our daily life and work. Every household and office of all sizes will purchase one. Some consumers pursue quality, while others focus on functionality and comfort. However, when purchasing, the first impression that a chair gives to consumers is its appearance. High-end office chairs not only require good quality, excellent functionality and comfort, but also a good appearance. The first thing consumers come into contact with is the appearance of the product. A more attractive and textured appearance can be favored and recognized by more consumers, making them more willing to understand and even buy it. Therefore, a better product appearance can give manufacturers more opportunities to reap greater benefits.

[0003] For chairs that use shaping cotton, manufacturers often use cloth covers to wrap the entire chair back and seat for the sake of aesthetics. If you want to apply shaping cotton to office chairs, the above method is definitely not applicable, because this approach is not only troublesome but also has poor results. The cloth cover can only be put on the chair back and cannot be put on the seat together to increase stability. Therefore, the stability of the cloth cover cannot be guaranteed and it may become crooked. The common method of embedding strips and grooves can solve the problem of poor stability, but it is not suitable for chair backs with shaping cotton. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, the utility model provides a back support body, including a peripheral portion located at the outer edge, with two embedding grooves opened on the peripheral portion, and the two embedding grooves can each be embedded with a mesh strip, so that the front and back sides of the back support body can be covered by the mesh cloth; an annular spacer is formed between the two embedding grooves, and the annular spacer can separate the two embedding grooves and give the back support body a sense of layering.

[0005] A chair back is further provided, comprising the above-mentioned back support body and two mesh cloths covering the front and rear surfaces of the back support body, wherein the inlay strips at the edges of the front and rear two mesh cloths are respectively embedded in the front and rear two embedding grooves, and the annular spacer is exposed between the two mesh cloths to form an exposed visible part. Not only the mesh cloths are firmly and stably arranged, but the exposed visible part formed by the annular spacer also makes the chair back more layered and provides a better visual effect. Different chair backs can have different colors, and the appearance of the same product can be enriched to meet the preferences of more consumers.

[0006] The technical solution of the utility model is achieved in this way:

[0007] A back support body comprises an outer peripheral portion located at the outer edge, wherein the outer surface of the outer peripheral portion is provided with two embedding grooves from the outside to the inside, and the two embedding grooves are arranged in a front-to-back interval to form an annular spacer portion between the two embedding grooves, and the annular spacer portion is arranged in a front-to-back interval to surround the outer peripheral portion along the edge contour of the outer peripheral portion.

[0008] The back support body is provided with two front and rear embedded grooves, which can enable the mesh to be installed on both the front and rear sides of the back support body. The problem of difficult installation of the mesh is solved by splitting the overall sleeve-shaped mesh into two front and rear mesh pieces, and the installation mode of the embedded groove can stably install the mesh; the annular spacer separates the two embedded grooves, and at the same time can give the back support body a sense of layering, thereby making the visual effect of the chair back better.

[0009] Preferably, the groove width of the embedding groove is in the range of 3-5mm, the spacing between the front and rear embedding grooves is in the range of 3-10mm, and the thickness of the annular spacer is also in the range of 3-10mm. The groove width of the embedding groove is in a reasonable range that is conducive to embedding, and can also ensure the embedding stability and the strength of the embedding strip; the spacing between the two embedding grooves is the thickness of the annular spacer. The function of the annular spacer is mainly to enhance the visual effect of the appearance. The annular spacer gives different visual effects to the user at different thicknesses. In the range of 3-10mm, the annular spacer is not cumbersome, and can give consumers the visual experience brought by the annular spacer, making the chair back more layered, while ensuring sufficient strength so that the annular spacer will not be easily damaged, extending the service life of the bracket.

[0010] Preferably, the back support body is a solid plate-like body or a hollow plate-like body. When the back support body is a solid plate-like body, the strength is better; when the back support body is a hollow plate-like body, the back support body is provided with a plurality of hollows to increase air permeability.

[0011] A chair back comprises a back support body as described above and two meshes respectively covering the front and rear surfaces of the back support body, wherein the edges of the meshes are provided with welts, and the two meshes are respectively embedded in two front and rear embedding grooves through their own welts, and an annular spacer is exposed between the two meshes to form an exposed visible part.

[0012] The mesh cloth is installed on the chair back through an embedding groove, and two front and rear spaced embedding grooves are respectively arranged on the outer periphery of the back support body, so that the mesh cloth can be firmly and stably arranged on the front and rear sides of the back support body, and can also be fully covered on the chair back like a cloth cover; an annular spacer is formed between the two embedding grooves, and the annular spacer is exposed between the two mesh cloths, so that the chair back has a more layered feel and provides a better visual effect. Different chair backs can have different colors, and the appearance of the same product can be enriched to meet the preferences of more consumers.

[0013] Preferably, the back support further comprises shaping cotton, which is arranged on the back support body and is located between the back support body and the mesh cloth on the front side of the back support body; the back support body further comprises a receiving portion, which is located inside the peripheral portion, and the back support body is recessed inward to form the receiving portion, and the receiving portion is configured to receive the shaping cotton. The thickness of the peripheral portion is greater than that of the receiving portion, and the receiving portion receives the shaping cotton to provide comfort, while the peripheral portion is used to enhance the overall strength of the chair back.

[0014] Preferably, two vertical limit strips are protruded from the outer periphery toward the receiving portion, and the limit strips are located on the left and right sides of the receiving portion, and the limit strips are configured to limit the left and right shaking of the shaping cotton. In order to make the chair back more comfortable, the shaping cotton is not only arranged on the receiving portion, but also extends outward to cover the outer periphery. At this time, the outer periphery has a weaker restriction on the shaping cotton, and the setting of the limit strips can further restrict the shaping cotton, so that the shaping cotton can be stably fitted with the back support body.

[0015] Preferably, the thickness of the accommodating portion is 2-4 mm. The accommodating portion is thin and can be used to accommodate the shaping cotton, while saving the material cost of the back support body.

[0016] Preferably, the back support body is integrally formed.

[0017] The design starting point, concept and beneficial effects of the utility model using the above technical solution are:

[0018] The mesh cloth is installed on the back support body through the embedding groove, and two front and rear embedding grooves spaced apart are respectively arranged on the outer periphery of the back support body, so that the mesh cloth can be firmly and stably arranged on the front and rear sides of the back support body, and can also be fully covered on the chair back like a cloth cover; an annular spacer is formed between the two embedding grooves, and the annular spacer is exposed between the two mesh cloths, so that the chair back has a more layered feel and provides a better visual effect. Different chair backs can have different colors, and the appearance of the same product can be enriched to meet the preferences of more consumers.

[0019] In chairs using shaping cotton, manufacturers often use cloth covers to wrap the entire chair back and seat for the sake of aesthetics. If you want to apply shaping cotton to office chairs, the above method is definitely not applicable, because this method is not only troublesome but also has poor effect. The cloth cover can only be put on the chair back and cannot be put on the seat together to increase stability. Therefore, the stability of the cloth cover cannot be guaranteed and it may be distorted. The common method of embedding strips and grooves can solve the problem of poor stability, but it is not suitable for chair backs with shaping cotton. Therefore, the back support structure of the utility model can be applied to chair backs with shaping cotton, thereby solving the above problem and realizing the use of shaping cotton chair backs on office chairs.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0030] In the description of the present invention, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0031] The specific implementation of the utility model is as follows:

[0032] like Figure 1 , 2As shown in Figures 4 and 7, the utility model provides a back support body 1, which is a plate-shaped body. The back support body 1 is configured such that mesh cloths are installed on both the front and rear sides thereof through the embedding grooves 2 with the embedding strips 8. The back support body 1 includes a peripheral portion 101 located at the outer edge, and the outer surface of the peripheral portion 101 is provided with two embedding grooves 2 from the outside to the inside, and the two embedding grooves 2 are arranged at intervals in front and back, and an annular spacer 3 is formed between the two embedding grooves 2, and the annular spacer 3 is surrounded by the peripheral portion 101 along the edge contour of the peripheral portion 101; the annular spacer 3 is configured such that when the embedding strips 8 of the two mesh cloths are embedded in the embedding grooves 2, the annular spacer 3 is exposed between the two mesh cloths.

[0033] The mesh cloth is installed in the back support body 1 through the embedding groove 2 of the embedding strip 8, and two front and rear embedding grooves 2 spaced apart are respectively arranged on the outer peripheral portion 101 of the back support body 1, so that the mesh cloth can be firmly and stably arranged on the front and rear sides of the back support body 1, and can also be fully covered on the chair back like a cloth cover; an annular spacer 3 is formed between the two embedding grooves 2, and the annular spacer 3 is exposed between the two mesh cloths, so that the chair back has a more layered feel and provides a better visual effect. Different chair backs can have different colors, and the appearance of the same product can be richer to meet the preferences of more consumers.

[0034] In chairs using shaping cotton 6, manufacturers often use cloth covers to wrap the entire chair back and seat for the sake of aesthetics. If you want to apply shaping cotton 6 to office chairs, the above method is definitely not applicable, because this method is not only troublesome but also has poor effect. The cloth cover can only be put on the chair back and cannot be put on the seat together to increase stability. Therefore, the stability of the cloth cover cannot be guaranteed and it may be distorted. The common method of embedding strips 8 and embedding grooves 2 can solve the problem of poor stability, but it is not suitable for the chair back of shaping cotton 6. Therefore, the back support body 1 structure of the utility model can be applied to the chair back of shaping cotton 6, thereby solving the above problem and realizing the use of shaping cotton 6 chair back on office chairs.

[0035] like Figure 1-6As shown, the back support body 1 is used in a chair back, which further includes a first mesh cloth 4 located at the front side, a second mesh cloth 5 located at the back side, and a shaping cotton 6 arranged on the back support body 1; the first mesh cloth 4 and the second mesh cloth 5 are both provided with a fillet 8, the fillet 8 of the first mesh cloth 4 is arranged in the fillet 8 on the front side of the back support body 1, and the fillet 8 of the second mesh cloth 5 is arranged in the fillet 8 on the back side of the back support body 1; the shaping cotton 6 is located between the first mesh cloth 4 and the back support body 1, and the first mesh cloth 4 covers the shaping cotton 6 and the back support body 1 from the front side and fixes them to the back support body 1. The shaping cotton 6 and the back support body 1 are separately injection molded. Compared with the method of injection molding the shaping cotton 6 onto the back support body 1 in the prior art, the chair back does not need to transport the back support body 1 multiple times, and only needs to transport the produced shaping cotton 6 from the sponge molding plant to the assembly plant, saving the cost of packaging and transportation.

[0036] Specifically, the back support body 1 also includes a receiving portion 102, which is located in the peripheral portion 101. The back support body 1 is recessed inward to form the receiving portion 102, and the receiving portion 102 is configured to receive the shaping cotton 6; the thickness of the peripheral portion 101 is greater than the thickness of the receiving portion 102, the receiving portion 102 receives the shaping cotton 6 to provide comfort, and the peripheral portion 101 is used to enhance the overall strength of the chair back; the thickness of the receiving portion 102 is 2-4mm; in the present embodiment, the thickness of the receiving portion 102 is 2.3mm, and the thickness of the receiving portion 102 is thin, which can be used to receive the shaping cotton 6, while saving the material cost of the back support body 1.

[0037] like Figure 2-4 As shown, two vertical limiting strips 7 are protruded from the peripheral part 101 toward the receiving part 102, and the limiting strips 7 are located on the left and right sides of the receiving part 102. The limiting strips 7 are configured to limit the left and right shaking of the shaping cotton 6; in order to make the chair back more comfortable, the shaping cotton 6 is not only arranged on the receiving part 102, but also extends outward to cover the peripheral part 101. At this time, the peripheral part 101 has a weak restriction on the shaping cotton 6, and the setting of the limiting strips 7 can further restrict the shaping cotton 6, so that the shaping cotton 6 can be stably fitted with the back support body 1. The back support body 1 is integrally formed, that is, the limiting strips 7, the peripheral part 101 and the receiving part 102 are all integrally formed.

[0038] Furthermore, if Figure 1 , 3As shown in , 4, and 7, the width of the embedding groove 2 is in the range of 3-5mm, the spacing between the front and rear embedding grooves 2 is in the range of 3-10mm, and the thickness of the annular spacer 3 is also in the range of 3-10mm; the width of the embedding groove 2 is in a reasonable range that is conducive to embedding, and can also ensure the embedding stability and the strength of the embedding strip 8; the spacing between the two embedding grooves 2 is the thickness of the annular spacer 3, and the function of the annular spacer 3 is mainly to enhance the visual effect of the appearance. The annular spacer 3 gives different visual effects to the user at different thicknesses. In the range of 3-10mm, the annular spacer 3 is not cumbersome, and can give consumers a visual experience brought by the annular spacer 3, making the chair back more layered, and at the same time, it can ensure sufficient strength, so that the annular spacer 3 will not be easily damaged, and the service life of the bracket is extended. In this embodiment, the width of the embedding groove 2 is 3.8mm, and the thickness of the annular spacer 3 is 4mm.
