Description

Technical Field

[0001] This application relates to the technical field of furniture manufacturing, and in particular to a curved tabletop structure. Background Technology

[0002] As people's aesthetic standards improve and their demands for comfort increase, they are paying more and more attention to the appearance and design of furniture. A rounded tabletop is generally made of three bamboo strips joined together. The upper and lower bamboo strips are both made of several longitudinal bamboo strips glued together, while the middle bamboo strip is made of several transverse bamboo strips glued together. Creating a curved groove on the side of the tabletop facing the user breaks the monotony of a flat edge, adds design depth, and avoids the harshness that right angles can bring, making the furniture appear softer.

[0003] When creating an arc-shaped groove, the groove can be made at the end of a longitudinal bamboo strip or at the end of a transverse bamboo strip. Taking the example of an arc-shaped groove at the end of a transverse bamboo strip... Figure 1 As shown, because the width of the horizontal bamboo strip is less than its length, many of the bonding points of adjacent horizontal bamboo strips are located on the inner wall of the arc groove. Over time, due to changes in temperature and humidity, the glue at multiple bonding points at the ends of the horizontal bamboo strips will expand, thus affecting the customer experience and requiring improvement. Utility Model Content

[0004] The purpose of this application is to provide a curved tabletop structure to reduce the number of bonding points within the curved groove.

[0005] The present application provides a circular arc tabletop structure with the following technical solution: A circular arc tabletop structure includes an upper bamboo board, a middle bamboo board bonded to the upper bamboo board, and a lower bamboo board bonded to the middle bamboo board. The middle bamboo board is located between the upper main board and the middle bamboo board. The upper bamboo board and the lower bamboo board are both formed by bonding several first longitudinal bamboo strips. Arc-shaped grooves are provided on the same side of the upper bamboo board, the middle bamboo board, and the lower bamboo board. The middle bamboo board includes at least one set of second longitudinal bamboo strips and a connecting bamboo board connected to one of the second longitudinal bamboo strips. The arc-shaped grooves are located on the sides of the first longitudinal bamboo strips and the second longitudinal bamboo strips.

[0006] By adopting the above technical solution, the arc-shaped groove is set on the side of the first and second longitudinal bamboo strips. At the same time, due to the change in the position of the arc-shaped groove, the situation where the bonding points of adjacent bamboo strips are located on the inner wall of the arc-shaped groove is reduced, thereby improving the aesthetics of the overall structure and reducing the possibility of glue expansion due to temperature and humidity changes affecting the user experience.

[0007] Optionally, two sets of the second longitudinal bamboo strips are bonded to the connecting bamboo board, with the connecting bamboo board located between the two sets of the second longitudinal bamboo strips.

[0008] By adopting the above technical solution, in the process of opening the arc groove, it is not necessary to specifically select one set of second longitudinal bamboo strips; any set of second longitudinal bamboo strips can be selected for opening, thereby improving the efficiency of processing the table.

[0009] Optionally, both the upper bamboo board and the lower bamboo board are provided with chamfers, and the chamfers are located on the inner wall of the arc-shaped groove.

[0010] By adopting the above technical solution, since the user will be sitting in the arc-shaped groove, setting chamfers on the upper and lower bamboo boards at the inner wall of the arc-shaped groove can remove burrs and sharp edges, reducing the risk of injury.

[0011] Optionally, the connecting bamboo board includes a middle reinforcing plate and two side reinforcing plates. The middle reinforcing plate is formed by bonding several first connecting bamboo strips together, and each side reinforcing plate is formed by bonding several second connecting bamboo strips together. The extension directions of the first connecting bamboo strips and the extension directions of the second longitudinal bamboo strips are staggered.

[0012] By adopting the above technical solution, the direction of the deformation resisted by the second longitudinal bamboo strip and the direction of the deformation resisted by the first longitudinal bamboo strip are different from the direction of the deformation resisted by the first connecting bamboo strip. Since the bamboo strips in different directions can restrain each other, the stability of the connection between the first longitudinal bamboo strip and the second longitudinal bamboo strip and the connecting bamboo board can be further improved, thereby improving the strength of the overall structure.

[0013] Optionally, the extension direction of the first connecting bamboo strip is perpendicular to the extension direction of the second longitudinal bamboo strip.

[0014] By adopting the above technical solution, the direction of the deformation resisted by the second longitudinal bamboo strip and the direction of the deformation resisted by the first longitudinal bamboo strip are different from the direction of the deformation resisted by the first connecting bamboo strip. Since the bamboo strips in different directions can restrain each other, the stability of the connection between the first longitudinal bamboo strip and the second longitudinal bamboo strip and the connecting bamboo board can be further improved, thereby improving the strength of the overall structure.

[0015] Optionally, the angle formed between the extension direction of the first connecting bamboo strip and the extension direction of the second longitudinal bamboo strip is an acute angle.

[0016] By adopting the above technical solution, the direction of the deformation resisted by the second longitudinal bamboo strip and the direction of the deformation resisted by the first longitudinal bamboo strip are different from the direction of the deformation resisted by the first connecting bamboo strip. Since the bamboo strips in different directions can restrain each other, the stability of the connection between the first longitudinal bamboo strip and the second longitudinal bamboo strip and the connecting bamboo board can be further improved, thereby improving the strength of the overall structure.

[0017] Optionally, the extension direction of the second connecting bamboo strip is staggered with the extension direction of the second longitudinal bamboo strip, and the extension direction of the second connecting bamboo strip is different from the extension direction of the first connecting bamboo strip.

[0018] By adopting the above technical solution, the direction of the deformation resisted by the second longitudinal bamboo strip and the direction of the deformation resisted by the first longitudinal bamboo strip are different from the direction of the deformation resisted by the second connecting bamboo strip. Furthermore, the direction of the deformation resisted by the second connecting bamboo strip is different from the direction of the deformation resisted by the first connecting bamboo strip. This can further improve the stability of the connection between the first connecting bamboo strip, the first longitudinal bamboo strip, and the second longitudinal bamboo strip and the second connecting bamboo strip, thereby improving the strength of the overall structure.

[0019] Optionally, the extension direction of the second connecting bamboo strip is perpendicular to the extension direction of the second longitudinal bamboo strip.

[0020] By adopting the above technical solution, since the second connecting bamboo strip is located on the side of the tabletop, the number of adjacent bamboo strip bonding points located on the side of the tabletop is reduced, thus improving the overall aesthetics of the structure.

[0021] Optionally, both ends of the second connecting bamboo strip are provided with limiting portions, and the corresponding second longitudinal bamboo strip is provided with limiting grooves, which are used to cooperate with the limiting portions.

[0022] By adopting the above technical solution, the contact area between the second connecting bamboo strip and the second longitudinal bamboo strip is increased by the limiting part, thereby improving the connection strength between the second connecting bamboo strip and the second longitudinal bamboo strip.

[0023] Optionally, the limiting part is a dovetail part, and the limiting groove is a dovetail groove, which is used to cooperate with the dovetail part.

[0024] By adopting the above technical solution, the dovetail and the dovetail groove form a snap-fit ​​connection, which further enhances the connection strength between the second connecting bamboo strip and the second longitudinal bamboo strip.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The arc-shaped groove is set on the side of the first and second longitudinal bamboo strips. At the same time, due to the change in the position of the arc-shaped groove, the number of adjacent bamboo strip bonding points located on the inner wall of the arc-shaped groove is reduced, which improves the aesthetics of the overall structure and reduces the possibility of glue expansion due to temperature and humidity changes affecting the user experience.

[0026] 2. The dovetail and the dovetail groove form a snap-fit ​​connection, which further enhances the connection strength between the second connecting bamboo strip and the second longitudinal bamboo strip. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 2 - Appendix Figure 7 This application will be described in further detail.

[0036] This application discloses a circular arc tabletop structure.

[0037] Combination Figure 2 and Figure 3As shown, it includes an upper bamboo board 1, a middle bamboo board 2 bonded to the upper bamboo board 1, and a lower bamboo board 3 bonded to the middle bamboo board 2. The middle bamboo board 2 is located between the upper bamboo board 1 and the lower bamboo board 3. The upper bamboo board 1 and the lower bamboo board 3 are both bonded together by several first longitudinal bamboo strips 11. The middle bamboo board 2 includes connecting bamboo boards 21 and at least one set of second longitudinal bamboo strips 22. Taking this embodiment as an example, there are two sets of second longitudinal bamboo strips 22. The middle bamboo board 2 is located between the two sets of second longitudinal bamboo strips 22. Both sets of second longitudinal bamboo strips 22 are bonded to the middle bamboo board 2. Each set of second longitudinal bamboo strips 22 is bonded together by several second longitudinal bamboo strips 22. The upper bamboo board 1, the middle bamboo board 2, and the lower bamboo board 3 all have arc-shaped grooves 12 on the same side. The arc-shaped grooves 12 are located on the sides of the first longitudinal bamboo strip 11 and the second longitudinal bamboo strip 22. Taking the second longitudinal bamboo strip 22 as an example, the side with the longer length of the second longitudinal bamboo strip 22 is the side face, and the side with the shorter length of the second longitudinal bamboo strip 22 is the end face. Both the upper bamboo board 1 and the lower bamboo board 3 have chamfers 13, which are located on the inner wall of the arc-shaped grooves 12.

[0038] like Figure 3 As shown, the connecting bamboo board 21 includes a central reinforcing plate 211 and two side reinforcing plates 212. The central reinforcing plate 211 is located between the two side reinforcing plates 212, and both side reinforcing plates 212 are bonded to the central reinforcing plate 211. The central reinforcing plate 211 is formed by bonding several first connecting bamboo strips 2111 together. The extension direction of the first connecting bamboo strips 2111 is staggered with the extension direction of the second longitudinal bamboo strips 22. Taking this embodiment as an example, the extension direction of the first connecting bamboo strips 2111 is perpendicular to the extension direction of the second longitudinal bamboo strips 22. Each side reinforcing plate 212 is formed by bonding several second connecting bamboo strips 2121 together. The extension direction of the second connecting bamboo strips 2121 is perpendicular to the extension direction of the first connecting bamboo strips 2111.

[0039] The implementation principle of a circular arc tabletop structure in this application embodiment is as follows: The arc-shaped groove 12 is opened on the side of the first longitudinal bamboo strip 11 and the second longitudinal bamboo strip 22. At the same time, due to the change in the position of the arc-shaped groove 12, the number of adjacent bamboo strip bonding points located on the inner wall of the arc-shaped groove 12 is reduced, which improves the aesthetics of the overall structure and reduces the possibility of glue expansion due to temperature and humidity changes affecting the user experience.

[0040] Example 2 The difference between this embodiment and Embodiment 1 is that, as Figure 4 As shown, the angle formed between the extension direction of the first connecting bamboo strip 2111 and the extension direction of the second longitudinal bamboo strip 22 is an acute angle.

[0041] Example 3 The difference between this embodiment and Embodiment 1 is that, as Figure 5As shown, the extension directions of the second connecting bamboo strip 2121 and the second longitudinal bamboo strip 22 are staggered, and the angle formed between the extension direction of the second connecting bamboo strip 2121 and the extension direction of the second longitudinal bamboo strip 22 is an acute angle. The extension direction of the second connecting bamboo strip 2121 is different from the extension direction of the first connecting bamboo strip 2111.

[0042] Example 4 The difference between this embodiment and embodiment 3 is that, as Figure 6 As shown, the second connecting bamboo strips 2121 in each side reinforcing plate 212 extend in different directions.

[0043] Example 5 The difference between this embodiment and embodiment 2 is that, as Figure 7 As shown, the extension direction of the second connecting bamboo strip 2121 is perpendicular to the extension direction of the second longitudinal bamboo strip 22. Each end of the second connecting bamboo strip 2121 is provided with a limiting part 2122, and each corresponding second longitudinal bamboo strip 22 is provided with a limiting groove 221. The limiting part 2122 is a dovetail part, and the limiting groove 221 is a dovetail groove.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
