COUPLING STRUCTURE FOR TABLES

Abstract

The present subject matter is directed to a table coupling structure, comprising a first table and a second table coupled to each other, wherein a respective coupling groove is formed on the coupling side of each tabletop. A coupling member is inserted into the first coupling groove and the second coupling groove to couple the first tabletop and the second tabletop. When coupling the table structure, it is only necessary to insert the coupling member into the first coupling groove and the second coupling groove, thereby enabling the first tabletop and the second tabletop to be coupled together. The connection is firm and stable during use. For disassembly, it only needs to pull out the coupling member, making both coupling and disassembly of the coupling structure convenient. In addition, multiple tables can be connected together as needed, and different coupling methods can be flexibly combined.

DETAILED DESCRIPTION

[0026] The present subject matter pertains to improved approaches for connecting tables or similar furniture. Embodiments of the present subject matter are discussed below with reference to FIGS. 1-9.

[0027] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present subject matter. It will be apparent, however, to one skilled in the art that the present subject matter may be practiced without some of these specific details. In addition, the following description provides examples, and the accompanying drawings show various examples for the purposes of illustration. Moreover, these examples should not be construed in a limiting sense as they are merely intended to provide examples of embodiments of the subject matter rather than to provide an exhaustive list of all possible implementations. In other instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the details of the disclosed features of various described embodiments.

Embodiment I

[0028] As shown in FIGS. 1 to 5, the table coupling structure of this embodiment includes a first table 1 and a second table 2 coupled to each other. The first table 1 has a first tabletop 11, and the second table 2 has a second tabletop 21. A first coupling groove 111 is formed on the coupling side of the first tabletop 11, and a second coupling groove 211 is formed on the coupling side of the second tabletop 21. A coupling member 3 is inserted into the first coupling groove 111 and the second coupling groove 211 to couple the first tabletop 11 with the second tabletop 21.

[0029] In this embodiment, both the first coupling groove 111 and the second coupling groove 211 are strip-shaped grooves. Correspondingly, the coupling member 3 has a rod-shaped insertion portion 31 and a limiting portion 32 provided at the rear end of the rod-shaped insertion portion 31. The rod-shaped insertion portion 31 is inserted into the first coupling groove 111 and the second coupling groove 211. In this embodiment, the first coupling groove 111 and the second coupling groove 211 are both T-shaped grooves. Correspondingly, the first coupling groove 111 and the second coupling groove 211 align to form an I-beam-shaped structure, and correspondingly, the cross-section of the rod-shaped insertion portion 31 is I-shaped.

[0030] A coupling gap 4 is formed between the first tabletop 11 and the second tabletop 21, and the limiting portion 32 is limited within the coupling gap 4. Specifically, the first tabletop 11 has an arc-shaped corner surface 5, and the second tabletop 21 also has an arc-shaped corner surface 5. A coupling gap 4 is formed between the arc-shaped corner surfaces 5 of the first tabletop 11 and the second tabletop 21. The side surface of the limiting portion 32 has a first arc-shaped surface 321 that matches the arc-shaped corner surfaces 5 of the first tabletop 11 and the second tabletop 21.

[0031] The coupling structure of this embodiment further includes a connecting base 6. A vertical insertion hole 322 is formed on the limiting portion 32. The connecting base 6 has an upwardly extending insertion post 61. The connecting base 6 abuts against the lower edges of the arc-shaped corner surfaces 5 of the first tabletop 11 and the second tabletop 21. The insertion post 61 is inserted upward into the vertical insertion hole 322. In addition, the side surface of the connecting base 6 has a second arc-shaped surface 62 that matches the arc-shaped corner surfaces 5 of the first tabletop 11 and the second tabletop 21. In this way, after installation, both the first arc-shaped surface 321 of the limiting portion 32 and the second arc-shaped surface 62 of the connecting base 6 are in contact with the arc-shaped transition surfaces 5 at the coupling gap 4, allowing the coupling member 3 to effectively limit the first tabletop 11 and the second tabletop 21.

[0032] In this embodiment, both the first tabletop 11 and the second tabletop 21 are rectangular. The first coupling groove 111 is provided on the short edge of the first tabletop 11, and the second coupling groove 211 is provided on the short edge of the second tabletop 21. The short edge of the first tabletop 11 is coupled to the short edge of the second tabletop 21. Taking the direction indicated by arrow B in FIG. 2 as the right direction, the first coupling groove 111 is formed on the left and right side walls of the first tabletop 11, and the second coupling groove 211 is formed on the left and right side walls of the second tabletop 21. After the first tabletop 11 and the second tabletop 21 are coupled to each other, the length of the tabletop becomes longer, forming a transverse coupling structure.

[0033] In this embodiment, a storage slot 7 is formed on the left side of the first tabletop 11 and on the right side of the second tabletop 21. The storage slot 7 can be used to place various items, thereby expanding the functionality of the table. It can also serve as a storage groove to hold items from the tabletop, making the tabletop tidier.

Embodiment II

[0034] As shown in FIGS. 6 and 7, the structure of the first table 1 and the second table 2 in this embodiment is the same as that in Embodiment 1. The difference from Embodiment 1 is that after the first table 1 and the second table 2 are coupled in this embodiment, the two storage slots 7 are positioned adjacent to each other.

[0035] In addition, the coupling member 3 in this embodiment does not have a connecting base, and the limiting portion 32 also does not have a vertical insertion hole. The rest of the structure is the same as in Embodiment I and will not be described again.

Embodiment III

[0036] As shown in FIG. 8, in this embodiment, the first coupling groove 111 is provided on the short edge of the first tabletop 11, and the second coupling groove 211 is provided on the long edge of the second tabletop 21. The short edge of the first tabletop 11 is coupled with the long edge of the second tabletop 21, forming a corner-type coupling structure. The coupling member 3 in this embodiment may be the same as the coupling member in Embodiments I and II.

Embodiment IV

[0037] As shown in FIG. 9, in this embodiment, the first coupling groove 111 is provided on the short edge of the first tabletop 11, and the second coupling groove 211 is provided on the short edge of the second tabletop 21. The short edge of the first tabletop 11 is coupled with the short edge of the second tabletop 21, and after coupling, a table with extended length is formed. The coupling member 3 in this embodiment may be the same as the coupling member in Embodiments I and II. The difference from Embodiment I is that in this embodiment, no storage slots are provided on the first tabletop 11 or the second tabletop 21. Instead, additional built-in storage shelfs are provided under both tabletops.

[0038] In addition, the long edge of the first tabletop 11 may be coupled with the short edge of the second tabletop 21, or the long edge of the first tabletop 11 may be coupled with the long edge of the second tabletop 21.
