Description

[Technical field]

[0001] The present invention relates to flooring materials, and in particular to an improved structure for chamfered flooring materials, which reduces the color difference in the grooves of chamfered joints after joining flooring materials of any color, improves the problem of color differences, and improves the appearance. [Background technology]

[0002] Hardwood flooring, also known as floating flooring, is a flooring material that is easy to design and can be quickly installed. Such flooring designs can be applied over hard surfaces such as concrete, tile, and traditional hardwood floors. Hardwood flooring includes composite (laminated) flooring, solid wood flooring, and other types. The basic elements of hardwood flooring installation technology are described below.

[0003] Locking System: The key to wood flooring is the locking system. The edges of these wood flooring are fitted with special tenons and grooves that allow the tenons to fit together without the need for any glue or nails. This system allows the wood flooring to be laid flat and can be easily removed or replaced if necessary.

[0004] Materials: Flooring materials are made of various materials. Typical ones are composite (laminated) flooring, which consists of a wear-resistant print layer, a picture layer (that looks like wood or stone), a high-density fiberboard (middle layer) and a bottom layer. Solid wood flooring is made of natural wood and looks very natural, but is expensive. Luxury vinyl flooring is made of vinyl-based resin, which can imitate various natural materials and is highly durable and waterproof.

[0005] Installation: Installing flooring is easy and does not require any specialized skills. Generally, flooring is arranged in the desired pattern and direction, and then compressed to be integrated. The locking system between the flooring allows the flooring to adhere to each other and form a smooth surface.

[0006] Protection: Flooring can be easily protected. Generally, cleaning is done with a dry or slightly damp cloth, but depending on the material of the flooring, some special cleaning products may be required.

[0007] However, the drawback of the prior art is that the color of the middle layer (non-PETG or ABS material) is monotonous and generally different from the color of the multi-colored wear-resistant printed layer, so the color of the chamfered area is generally different from the color of the groove at the joint after the flooring material is joined, making it look unsightly and unbalanced, and even more so, in order to hide the color difference, secondary processing is performed, and the edges are manually painted with colored pens to match the color of the wear-resistant printed layer. To avoid this problem and the trouble involved, it has been common not to produce products with chamfers when designing, manufacturing, and producing printed flooring.

[0008] In view of the above circumstances, the present inventor has made various efforts based on his / her many years of experience and knowledge in manufacturing and design in the related fields, and has completed the present invention.

[0009] In view of the above circumstances, the present inventors have conducted extensive research, carried out improvements and prototypes, and have thus completed the present invention. Summary of the Invention [Problem to be solved by the invention]

[0010] The main objective of the present invention is to provide an improved structure for chamfered flooring, which can reduce the color difference of the chamfered joint groove after joining regardless of the color of the flooring, or prevent the problem of color difference from occurring, and improve the appearance. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] In order to more fully and clearly disclose the technical means of the present invention and the effects achievable thereby, the present invention will be described in detail below in conjunction with the accompanying drawings and symbols disclosed.

[0022] Please refer to Figures 1 to 4. Figure 1 is a perspective view (1) showing an improved structure of a chamfered flooring material according to one embodiment of the present invention. Figure 2 is a perspective view (2) showing an improved structure of a chamfered flooring material according to one embodiment of the present invention. Figure 3 is an exploded perspective view showing an improved structure of a chamfered flooring material according to one embodiment of the present invention. Figure 4 is a side view showing an improved structure of a chamfered flooring material according to one embodiment of the present invention.

[0023] As shown in FIGS. 1 to 4, a chamfered flooring material 1 included in an improved structure of a chamfered flooring material according to one embodiment of the present invention comprises a bottom layer 11 and a flooring layer 2.

[0024] A first connecting portion 111 and a second connecting portion 112 are provided on the sides of the bottom layer 11. The first connecting portion 111 is connected to the second connecting portion 112 of the other chamfered flooring material 1. The second connecting portion 112 is connected to the first connecting portion 111 of the other chamfered flooring material 1. Preferably, the bottom layer 11 is made of MDF (Medium Density Fiberboard), SPC (Solid Polymer Core), Polyvinyl Chloride (PVC), Foam, or Laminated Veneer Lumber. The first connecting portion 111 has a male connector structure, and the second connecting portion 112 has a female connector structure, and the first connecting portion 111 and the second connecting portion 112 can be connected to each other. The thickness of the bottom layer 11 is 1 mm to 25 mm, but is not limited thereto.

[0025] The flooring layer 2 is formed on the bottom layer 11, and has chamfers 21 on each of the top four sides. The flooring layer 2 includes a same-color layer 22 and an abrasion-resistant printed layer 23. The abrasion-resistant printed layer 23 is formed on the same-color layer 22. The same-color layer 22 is preferably made of polyethylene terephthalate glycol (PETG) or acrylonitrile-butadiene-styrene (ABS). The abrasion-resistant printed layer 23 is made of polypropylene (PP), polyvinyl chloride (PVC) or paper. Preferably, the flooring layer 2 has chamfers 21 on each of the top four sides. The depth of the chamfer 21 is 0.05 mm to 0.8 mm, the thickness of the same color layer 22 is 0.2 mm to 1 mm, and the thickness of the abrasion-resistant printed layer 23 is 0.05 mm to 0.5 mm, but is not limited thereto.

[0026] In detail, the same-color layer 22 may be of a single color (e.g., any color such as white, black, gray, yellow, red, etc.), and this color is similar to the color of the abrasion-resistant printing layer 23. Additional advantages of using PETG or ABS for the same-color layer 22 include the following (1) to (6). (1) The three-layer structure improves the balance of the flooring. (2) The hardness and toughness of the abrasion-resistant printing layer 23 can be increased. (3) The weather resistance and whitening resistance of the abrasion-resistant printing layer 23 can be improved. (4) The materials used do not pollute the environment. (5) It is easy to process. (6) A wide variety of single colors can be produced. The abrasion-resistant printing layer 23 can be printed with various colors, natural patterns and totems, and can also be subjected to abrasion-resistant treatment.

[0027] Based on the above-mentioned structure and composition design, the operating conditions of the present invention will be described below. Please refer to FIG. 5. FIG. 5 is an explanatory diagram of the state of using the improved structure of the chamfered flooring according to one embodiment of the present invention. As shown in FIG. 5, the top four sides of the flooring layer 2 of this embodiment are each provided with a chamfer 21. That is, the short side and long side of the chamfered flooring 1 are each provided with a chamfer 21, and when multiple chamfered flooring 1 are combined, a groove is formed between the two chamfers 21. Each chamfered flooring 1 can be connected to each other using a first connecting portion 111 and a second connecting portion 112. More specifically, the first connecting portion 111 is a male connector structure, and the second connecting portion 112 is a female connector structure, and they can be connected to each other.

[0028] Please refer to Figure 6. Figure 6 is an explanatory diagram of the state of using the improved structure of the chamfered flooring material according to another embodiment of the present invention. As shown in Figure 6, chamfers 21 are provided on both sides of the top of the flooring layer 2 of this embodiment, and are installed on the long side, and multiple chamfered flooring materials 1 are combined to form a groove between the two chamfers 21. Here, no groove is formed at the joint of the short side.

[0029] Please refer to Figure 7. Figure 7 is an explanatory diagram of the state of using the improved structure of chamfered flooring according to another embodiment of the present invention. As shown in Figure 7, the improved structure of chamfered flooring according to another embodiment of the present invention has chamfers 21 on each of the chamfered flooring materials 1 to be joined together, and therefore has the following advantages (1) to (3). (1) Visual Abilities: The three-dimensional texture of the chamfers 21 makes the flooring appear multi-layered and like real wood, with a texture close to that of real wood, making the flooring appear flatter and improving the sense of spatial extension and appearance. (2) Functionality: Since flooring materials have the characteristic of expanding when heated and contracting when cooled, the degree of expansion and contraction of each flooring material is different. Therefore, if there is no chamfer 21, the joints will not be flat. By providing chamfer 21, gaps will be created at the joints between flooring materials to act as buffers, which can improve the problem of height differences caused by pressure on the flooring, making construction easier. The durability of the corners of the flooring materials can be improved, improving the anti-slip effect of the flooring materials, and extending their service life. (3) Safety: If it is designed with a right angle, burrs and crushed corners are likely to occur, but if it is designed with a smooth shape, scratches are prevented and the chamfering 21 can increase the anti-slip effect of the flooring material, making it very safe.

[0030] The same-color layer 22 of the present invention uses polyethylene terephthalate glycol (PETG), amorphous copolyester material, or three-component copolymer such as acrylonitrile-butadiene-styrene (ABS), which has various special advantages, and can be produced in a single color selected from various colors. After combining with a wear-resistant printing layer 23 of a different color, the edge of the board is scraped to form chamfers 21 of different widths (0.05mm to 0.8mm), which prevents color differences from occurring in the grooves of the joints when combined with flooring materials.

[0031] As can be seen from the above, the improved structure of the chamfered flooring material according to the present invention, when actually used, reduces the color difference in the groove at the chamfer 21 after joining, regardless of the color of the flooring material, compared to the prior art, and can solve the problem of color difference and improve the appearance.

[0032] The preferred embodiments of the present invention have been disclosed above so that those skilled in the art can understand, but they are not intended to limit the present invention. Various changes and modifications can be made within the scope of the present invention. Therefore, the claims of the present invention should be interpreted broadly to include such changes and modifications. [Explanation of symbols]
