[0002] This application claims priority to Chinese Patent Application No. 202411527671.3, entitled "A Floor Including a Coupling Component," filed on October 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the technical field of flooring, and particularly to a flooring comprising a coupling component. Background Technology

[0004] Flooring, as a cladding material for both interior and exterior buildings, has significant functional and aesthetic value. Interlocking flooring is a type of flooring that combines multiple floorboards using a specific connection method, typically employing a click-lock or tongue-and-groove structure. Its main advantages include ease of installation, no need for glue, and easy disassembly and replacement. However, existing interlocking flooring often uses straight-edged tongues and grooves during production. This straight-edged tongue and groove joint can be less secure, leading to loosening at the joints and widening gaps during use, thus affecting the lifespan of the flooring.

When two flooring units are connected, the first side portion is inserted into the first groove, and the second side portion is inserted into the second groove. Since the first connecting surface of the second side portion and the third connecting surface of the second groove are both inclined relative to the flooring body, when the two flooring units are connected, the first connecting surface and the third connecting surface abut against each other, which can provide locking of the flooring units in the horizontal and vertical directions when the two flooring units are connected, thereby improving the stability and reliability of the flooring connection and enhancing the connection strength of the flooring units.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0045] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0046] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the term "and / or" throughout the text includes three solutions; taking A and / or B as an example, it includes technical solution A, technical solution B, and a technical solution that simultaneously satisfies A and B. Furthermore, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0047] Referring to Embodiment 1 in Figures 1-9, this application provides a floor including coupling components. The floor includes a floor body 1, a first coupling component 2, and a second coupling component 3. The first coupling component 2 and the second coupling component 3 are disposed on opposite sides of the floor body 1. The first coupling component 2 includes a first tongue 4, and the second coupling component 3 has a first mortise 5. The first mortise 5 is used to accommodate at least a portion of the first tongue 4 to achieve the connection of multiple floor panels.

[0048] The first tenon 4 includes a first side portion 6, a second side portion 7, a first bottom portion 8, and a third side portion 9. The first side portion 6 is at least partially inclined downward toward the direction of the second coupling member 3. The second side portion 7 protrudes toward the side away from the second coupling member 3. The second side portion 7 includes a first connecting surface 10 and a second connecting surface 11. The first connecting surface 10 is at least partially inclined downward from the bottom end of the first side portion 6 toward the direction of the second coupling member 3. The second connecting surface 11 is at least partially inclined downward from the bottom end of the first connecting surface 10 toward the direction of the second coupling member 3. The first bottom portion 8 extends from the end of the second connecting surface 11 away from the first connecting surface 10 toward the direction of the second coupling member 3. The third side portion 9 is at least partially inclined downward in the direction of the second coupling member 3 and is connected to the end of the first bottom portion 8 away from the second side portion 7.

[0049] The first tenon 5 includes a first groove 12 and a second groove 13. The first groove 12 is located above the second groove 13. Both the first groove 12 and the second groove 13 are recessed towards the first coupling member 2. The second groove 13 includes a third connecting surface 14, a fourth connecting surface 15, a first base surface 16, and a second base surface 17. The third connecting surface 14 slopes downward at least partially from the bottom end of the first groove 12 towards the first coupling member 2. The fourth connecting surface 15 slopes downward at least partially from the bottom end of the third connecting surface 14 away from the first coupling member 2. The first base surface 16 extends from the bottom end of the fourth connecting surface 15 away from the first coupling member 2. The second base surface 17 slopes downward at least partially towards the first coupling member 2 and is connected to the end of the first base surface 16 away from the fourth connecting surface 15.

[0050] In Embodiment 1, when the floor is in the connected state, the first side portion 6 and the first groove 12 enclose to form a first cavity 18. The first connecting surface 10 and the third connecting surface 14 abut against each other to provide locking of the floor in the horizontal and vertical directions in the connected state. The first connecting surface 10, the second connecting surface 11, the third connecting surface 14 and the fourth connecting surface 15 enclose to form a second cavity 19. The first base surface 16 abuts against the first bottom 8 to provide locking in the vertical direction for the floor connection. The second base surface 17 abuts against the third side portion 9 to further provide horizontal and vertical force components for the floor connection, thereby improving connection stability.

[0051] Since there are some dimensional errors when the floorboards are grooved, the presence of the first cavity 18 and the second cavity 19 can reduce the phenomenon that the upper part of the two floorboards is not aligned when they are joined together due to the dimensional errors caused by the grooving.

[0052] The first bottom 8 is set horizontally and parallel to the width direction of the floor body 1.

[0053] Specifically, the horizontal direction is parallel to the width direction of the floor body 1, and the vertical direction is parallel to the thickness direction of the floor body 1.

[0054] Specifically, the first connecting surface 10 and the second connecting surface 11 are connected by a rounded transition, and the third connecting surface 14 and the fourth connecting surface 15 are connected by a rounded transition. The design of the rounded surface can reduce the friction when the first tenon 4 and the first mortise 5 are joined, making the joining process smoother and avoiding jamming.

[0055] Specifically, the first coupling component 2 further includes a fifth connecting surface 20, and the second coupling component 3 further includes a sixth connecting surface 21. The fifth connecting surface 20 is vertically or obliquely disposed above the first side portion 6 and connected to the top surface of the floor. The sixth connecting surface 21 is vertically or obliquely disposed above the first groove 12 and connected to the top surface of the floor. The fifth connecting surface 20 and the sixth connecting surface 21 have the same angle of inclination relative to the thickness direction of the floor body 1, so as to achieve seamless splicing of the fifth connecting surface 20 and the sixth connecting surface 21. Furthermore, there is a certain distance between the first cavity 18 and the top surface 56 of the floor. The upper part of the side of the first coupling component 2 of one floor and the second coupling component 3 of the other floor can be tightly attached to each other, that is, the fifth connecting surface 20 of the first coupling component 2 and the sixth connecting surface 21 of the second coupling component 3 are tightly attached, which not only meets the aesthetic requirements but also prevents debris from entering the first cavity 18.

[0056] Referring to Figures 6 and 8, the first coupling component 2 further includes a second tenon 22, and the second coupling component 3 also has a second mortise 23. The second tenon 22 is disposed inside the first tenon 4, and the second mortise 23 is disposed outside the first mortise 5. The second mortise 23 is used to accommodate at least a portion of the second tenon 22.

[0057] Referring to Figures 6 and 7, the second tenon 22 includes a fourth side portion 24, a second bottom portion 25, and a fifth side portion 26. The fourth side portion 24 extends downward at least partially and is connected to one end of the second bottom portion 25. The second bottom portion 25 extends from the bottom end of the fourth side portion 24 in a direction away from the first tenon 4. The fifth side portion 26 extends downward at least partially and is connected to the other end of the second bottom portion 25.

[0058] Specifically, the fourth side portion 24 includes a first straight portion 27, a first inclined portion 28, a second straight portion 29, and a second inclined portion 30. The first straight portion 27 extends downward. The first inclined portion 28 slopes downward at least partially from one end of the first straight portion 27 toward the direction close to the first tenon 4. The second straight portion 29 extends downward from the end of the first inclined portion 28 away from the first straight portion 27. The second inclined portion 30 slopes downward at least partially from the end of the second straight portion 29 away from the first inclined portion 28 toward the direction away from the first tenon 4 and connects to one end of the second bottom portion 25. The second bottom portion 25 extends downward from the second inclined portion 30 away from the second tenon 4. One end of the straight portion 29 extends away from the first tenon 4. The fifth side portion 26 includes a third inclined portion 31, a fourth inclined portion 32 and a fifth inclined portion 33 connected together. The third inclined portion 31 is at least partially inclined downward in the direction close to the first tenon 4 and is connected to the end of the second bottom 25 away from the second inclined portion 30. The fourth inclined portion 32 is at least partially inclined downward in the direction away from the first tenon 4 and is connected to the end of the third inclined portion 31 away from the second bottom 25. The fifth inclined portion 33 is at least partially inclined downward in the direction close to the first tenon 4 and is connected to the end of the fourth inclined portion 32 away from the third inclined portion 31.

[0059] Specifically, the second bottom 25 includes the third straight section, which is basically flat.

[0060] Correspondingly, referring to Figures 8 and 9, the second mortise 23 includes a first plane 34, a first inclined plane 35, a second plane 36, a second inclined plane 37, a third plane 38, a third inclined plane 39, a fourth inclined plane 40, and a fifth inclined plane 41 connected in sequence. The first plane 34 extends downward. The first inclined plane 35 slopes downward at least partially from one end of the first plane 34 toward the direction close to the first mortise 5. The second plane 36 extends downward from the end of the first inclined plane 35 away from the first plane 34. The second inclined plane 37 slopes downward at least partially from the end of the second plane 36 away from the first inclined plane 35 toward the direction away from the first mortise 5. The third plane 38 extends from the end of the second inclined plane 37 away from the second plane 36 toward the direction away from the first mortise 5. The third inclined plane 39 slopes downward toward the direction close to the first mortise 5 and is parallel to the third plane 38 away from the second inclined plane 37. One end is connected, the fourth inclined surface 40 is at least partially inclined downward in the direction away from the first tenon 5 and is connected to the end of the third inclined surface 39 away from the third plane 38, the fifth inclined surface 41 is at least partially inclined downward in the direction close to the first tenon 5 and is connected to the end of the fourth inclined surface 40 away from the third inclined surface 39. When the two floorboards are connected, the first plane 34 is used to abut against the first straight part 27, the first inclined surface 35 is used to abut against the first inclined part 28, the second plane 36 is used to abut against the second straight part 29, the second inclined surface 37 is used to abut against the second inclined part 30, the third plane 38 is used to abut against the second bottom 25, the third inclined surface 39 is used to abut against the third inclined part 31, the fourth inclined surface 40 is used to abut against the fourth inclined part 32, and the fifth inclined surface 41 is used to abut against the fifth inclined part 33, which further improves the connection stability when the floorboards are connected.

[0061] As shown in Figure 5, when the floor is installed, the first tenon 5 and the second tenon 23 face upwards, and the first tenon 4 and the second tenon 25 face downwards.

[0062] In this embodiment, the vertical distance from the first bottom 8 to the top surface of the floor 56 is greater than the vertical distance from the second bottom 25 to the top surface of the floor 56, which is beneficial for the first tenon 4 to be inserted into the first mortise 5 during installation.

[0063] Referring to Figures 3 and 6-9, a third mortise 42 is formed between the first tenon 4 and the second tenon 22, and a third tenon 43 is formed between the first mortise 5 and the second mortise 23. The third tenon 43 is used to fit into the third mortise 42. A sixth inclined portion 44 is provided between the third side 9 and the fourth side 24. The sixth inclined portion 44 is inclined downward at least partially from the end of the third side 9 away from the first bottom 8 in a direction away from the first tenon 4 and is connected to the end of the fourth side 24 away from the second bottom 25. The third side 9, the sixth inclined portion 44 and the fourth side 24 surround and form the third mortise 42.

[0064] Specifically, the second coupling component 3 further includes a sixth inclined surface 45. The sixth inclined surface 45 slopes downward from the end of the second base surface 17 away from the first base surface 16 in a direction away from the first tenon 5 and connects to the end of the first plane 34 away from the first inclined surface 35. The second base surface 17, the sixth inclined surface 45, the first plane 34, the first inclined surface 35, the second plane 36, and the second inclined surface 37 form a third tenon tongue 43. When the two floorboards are connected, the second base surface 17 is used to abut against the third side portion 9, the sixth inclined surface 45 is used to abut against the sixth inclined portion 44, the first plane 34 is used to abut against the first straight portion 27, the first inclined surface 35 is used to abut against the first inclined portion 28, the second plane 36 is used to abut against the second straight portion 29, and the second inclined surface 37 is used to abut against the second inclined portion 30.

[0065] Furthermore, the first coupling component 2 also has a fourth mortise 46. The first coupling component 2 also includes a fourth straight section 47 and a fifth straight section 48. The fourth straight section 47 extends from the end of the fifth inclined portion 33 away from the fourth inclined portion 32 in a direction away from the first tenon 4. The fifth straight section 48 extends downward from the end of the third plane 38 away from the fifth inclined portion 33. The third inclined portion 31, the fourth inclined portion 32, the fifth inclined portion 33, the fourth straight section 47, and the fifth straight section 48 together form the fourth mortise 46.

[0066] In Embodiment 1, the fourth straight segment 47 extends horizontally and the fifth straight segment 48 extends vertically. In other embodiments, the fifth straight segment 48 is inclined relative to the floor body 1. Furthermore, the angle of inclination of the fifth straight segment 48 relative to the thickness direction of the floor body 1 is 30-60 degrees, preferably 40-50 degrees.

[0067] Correspondingly, the second coupling component 3 also includes a fourth tenon 49, a fourth plane 50, and a fifth plane 51. The fourth plane 50 extends from the end of the fifth inclined plane 41 away from the fourth inclined plane 40 in a direction away from the first mortise 5. The fifth plane 51 extends downward from the end of the fourth plane 50 away from the fifth inclined plane 41. The third inclined plane 39, the fourth inclined plane 40, the fifth inclined plane 41, the fourth plane 50, and the fifth plane 51 enclose to form the fourth tenon 49. The fourth tenon 49 is inserted into the fourth mortise 46. The third inclined plane 39 abuts against the third inclined portion 31, the fourth inclined plane 40 abuts against the fourth inclined portion 32, the fifth inclined plane 41 abuts against the fifth inclined portion 33, the fourth plane 50 abuts against the fourth straight section 47, and the fifth plane 51 abuts against the fifth straight section 48.

[0068] In this embodiment, the fourth plane 50 extends horizontally and the fifth plane 51 extends vertically. In other embodiments, the fifth plane 51 is inclined relative to the floor body 1. Furthermore, the fifth plane 51 and the fifth straight segment 48 have the same inclination angle. The inclination angle of the fifth plane 51 relative to the thickness direction of the floor body 1 is 30-60 degrees, preferably 40-50 degrees.
