INTERLOCKING SPLICING FLOOR PANEL

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an interlocking splicing floor panel which uses an edge sealing structure to cover the periphery of a base material main body, and uses a configuration design that a rib portion is embedded in the base material main body to increase the firmness of the combination of the edge sealing structure with the base material main body, and meanwhile also prevent moisture from entering the base material main body through the periphery thereof, thereby effectively extending the lifespan of the interlocking splicing floor panel.

2. Description of the Related Art

When constructing traditional wooden floors, it is usually necessary to lay a layer of plywood before construction. The wooden floors are usually joined together by using tongue and groove joints, and then fixed with glue and nails. It requires high technique for the construction workers and takes a long time to construct. Interlocking floor panels use an interlocking structure instead of the tongue and groove joints so that all floor panels are connected with each other at an appropriate angle. It only needs a rubber hammer for adjustment to accomplish the entire flooring. Compared with the constructing manner of the traditional wooden floors, the interlocking floor panel can not only significantly reduce the overall construction time, but also requires less technique for the construction workers.

US Patent Publication U.S. Pat. Nos. 10,926,509 and No. 9,290,951 both provide a floor panel structure, wherein the floor panel is provided on top and bottom surfaces thereof with edge bands or veneers, and the floor panel is formed at left and right ends thereof with locking strips. Two adjacent floor panels can use the locking strips to be combined with each other. However, the interlocking floor panels mostly use high density boards, particle boards or plywoods as their base material. These materials are not waterproof. In the condition that only the top and bottom surfaces of the floor panel are covered with edge bands but four sides of the floor panel are provided with no edge band, moisture will still enter the gap between two floor panels, resulting in that the base material of the floor panel absorbs too much moisture to cause expansion and deformation.

Besides, in the current design that edge bands 41 are added to the periphery of the floor panel 40, the inside surface of the edge band 41 is directly attached to the end surface 42 of the floor panel 40. However, the periphery of the floor panel 40 has no other fastening structure, so the edge band 41 made of plastic cannot be greatly combined with the floor panel 40 made of wood, as shown in FIG. 1. For this configuration design, after the use for a period of time, looseness will gradually happen between the edge band 41 and the floor panel 40 to produce a gap, causing loss of the waterproof effect.

Therefore, the inventor made effort to think about how to provide a structure which can make the edge band and the floor panel combined tightly, making the edge band completely seal the periphery of the floor panel to avoid the entering of moisture and the resulting damage to the floor panel.

SUMMARY OF THE INVENTION

In view of the fact that the above-described existing floor panel structures still have many shortcomings, it is a primary objective of the present invention to provide an interlocking splicing floor panel which uses the configuration design of an edge sealing structure and a base material main body to enable the two members made of different materials to be combined tightly, so as to lower the damage rate of the interlocking splicing floor panel.

To attain the above primary objective, the present invention provides an interlocking splicing floor panel which includes a base material main body and an edge sealing structure. The base material main body has a plurality of end surfaces, and a combining groove formed on the plurality of end surfaces. Each of the end surfaces is formed with a stair portion. The edge sealing structure is disposed on the plurality of end surfaces of the base material main body. The edge sealing structure has a rib portion formed on the inside surface of the edge sealing structure, and an interlocking member formed on the outside surface of the edge sealing structure. The rib portion is embedded in the combining groove of the base material main body.

By the above-described technical features, the combining groove formed on the end surfaces on the periphery of the base material main body is adapted for the rib portion of the edge sealing structure to be embedded therein, such that the edge sealing structure cannot be easily separated from the base material main body and can be relatively more tightly fixed to the base material main body to completely seal the periphery of the base material main body. Besides, the interlocking member on the outside surface of the edge sealing structure enables interlocking splicing floor panels to be interlocked with each other so as to be spliced into a complete floor. The gap between two floor panels is protected by the edge sealing structure, so moisture cannot enter the base material main body through the periphery thereof, so that the interlocking splicing floor panel will not absorb too much moisture to cause expansion and deformation.

Preferably, the base material main body further has a top surface and a bottom surface. The top surface is provided with a first decoration plate. The bottom surface is provided with a second decoration plate. As a result, the first decoration plate and the second decoration plate can provide the appearance of different veins, and have the property of wear-resistance to reduce the chance of the veins being worn off.

Preferably, each of the first decoration plate and the second decoration plate is applied on the surface thereof with a waterproof coating. As a result, the waterproof coatings are adapted to protect the upper and lower surfaces of the base material main body, capable of preventing moisture from entering the base material main body through the upper and lower surfaces thereof.

Preferably, the edge sealing structure is combined to the plurality of end surfaces of the base material main body through a hot melt process. As a result, the hot melt process can make the edge sealing structure completely fill the combining groove of the base material main body and solidified to become the rib portion, so that the edge sealing structure and the base material main body are firmly combined together.

Preferably, the material of the edge sealing structure is polypropylene-random (PPR). As a result, polypropylene-random has the properties of shock resistance, water pressure resistance, and high and low temperature resistance, thereby quite suitable for the edge sealing structure of the interlocking splicing floor panel.

Preferably, the interlocking member of the edge sealing structure has a first interlocking portion, a second interlocking portion, a third interlocking portion, and a fourth interlocking portion. The first interlocking portion and the second interlocking portion are disposed on the end surfaces on two long sides of the base material main body respectively. The third interlocking portion and the fourth interlocking portion are disposed on the end surfaces on two short sides of the base material main body respectively. As a result, the four sides of the base material main body are completely covered by the edge sealing structure, that provides greatly sealed structure to prevent moisture from entering the base material main body.

Preferably, the first interlocking portion is formed with a first extending strip, a first protruding strip, and a first interlocking groove. The first extending strip extends and protrudes outwardly from an edge of the first interlocking portion corresponding in position to the stair portion. The first protruding strip is formed at a position of the first interlocking portion corresponding to the stair portion. The first interlocking groove is formed between the first protruding strip and the outside surface of the first interlocking portion.

Preferably, the second interlocking portion is formed with a second extending strip, a second protruding strip, and a second interlocking groove. The second extending strip extends and protrudes outwardly from a position adjacent to the bottom side of the second interlocking portion. The second protruding strip is formed at an end of the second extending strip. The second interlocking groove is formed between the second extending strip and a position of the second interlocking portion corresponding to the stair portion. As a result, the second interlocking groove of the second interlocking portion of a first interlocking splicing floor panel is adapted for the first extending strip of the first interlocking portion of a second interlocking splicing floor panel to be inserted therein, and the second protruding strip of the first interlocking splicing floor panel is correspondingly inserted in the first interlocking groove of the second interlocking splicing floor panel, so that the two interlocking splicing floor panels are combined with each other firmly.

Preferably, the third interlocking portion is formed with a third extending strip, a third protruding strip, and a third interlocking groove. The third extending strip extends and protrudes outwardly from a position of the third interlocking portion adjacent to the stair portion. The third protruding strip is formed at an end of the third extending strip. The third interlocking groove is formed between the third protruding strip and the outside surface of the third interlocking portion.

Preferably, the fourth interlocking portion is formed with a fourth extending strip, a fourth protruding strip, and a fourth interlocking groove. The fourth extending strip extends and protrudes outwardly from a position of the fourth interlocking portion adjacent to the stair portion. The fourth protruding strip is formed at an end of the fourth extending strip. The fourth interlocking groove is formed between the fourth protruding strip and the outside surface of the fourth interlocking portion. As a result, the fourth protruding strip of the fourth interlocking portion of a first interlocking splicing floor panel can be inserted in the third interlocking groove of a second interlocking splicing floor panel, at the same time making the third protruding strip of the second interlocking splicing floor panel inserted in the fourth interlocking groove of the first interlocking splicing floor panel, so that the two interlocking splicing floor panels are combined with each other firmly.

Referring to FIG. 2 to FIG. 5, an interlocking splicing floor panel 10 of the present invention primarily includes a base material main body 20 and an edge sealing structure 30.

The base material main body 20 has a plurality of end surfaces 21 and at least one combining groove 22. The amount of the end surfaces 21 depends on the shape of the base material main body 20. In this embodiment, the base material main body 20 is rectangular in shape, thereby having four end surfaces 21. The combining groove 22 is formed continuously in a concaved manner on the four end surfaces 21. In this embodiment, the base material main body 20 is provided with two combining grooves 22 for the increase of the fixing force for the edge sealing structure 30, but a single combining groove 22 is still quite firm. Besides, each of the end surfaces 21 is formed with a stair portion 23, so that the base material main body 20 is shaped with wide top and narrow bottom. The base material main body 20 has a top surface 24 and a bottom surface 25. The top surface 24 is provided with a first decoration plate. The bottom surface 25 is provided with a second decoration plate. The first decoration plate is provided for the user to step thereon. Each of the first decoration plate and the second decoration plate is applied on the surface thereof with a waterproof coating. In general, the first decoration plate and the second decoration plate are also provided with wear-resistant layers for protecting the veins of the first decoration plate and the second decoration plate from being worn off, thereby maintaining good-looking appearance for a long time.

The material of the edge sealing structure 30 is polypropylene-random, which is applied to the end surfaces 21 on the periphery of the base material main body 20 by a hot melt process. The polypropylene-random is injected into the combining grooves 22 of the base material main body 20 to be formed into rib portions 31 of the edge sealing structure 30, so that the rib portions 31 are embedded in the combining grooves 22. The edge sealing structure 30 is also formed according to the interlocking structure design thereof with an interlocking member 32. In this way, the edge sealing structure 30 is formed with a rectangular shape for corresponding to the rectangular shape of the base material main body 20, and the edge sealing structure 30 completely covers and seals the four end surfaces 21 of the base material main body 20.

The interlocking member 32 of the edge sealing structure 30 has a first interlocking portion 321, a second interlocking portion 322, a third interlocking portion 323, and a fourth interlocking portion 324. The first interlocking portion 321 and the second interlocking portion 322 are located on the end surfaces 21 on two long sides of the base material main body 20 respectively. The third interlocking portion 323 and the fourth interlocking portion 324 are located on the end surfaces 21 on two short sides of the base material main body 20 respectively. The four interlocking portions are formed with different shapes. The first interlocking portion 321 requires the shape for being engaged with the second interlocking portion 322, and the third interlocking portion 323 requires the shape for being engaged with the fourth interlocking portion 324, so that two interlocking splicing floor panels 10 can use the long sides or short sides thereof to be combined with each other.

The first interlocking portion 321 is formed with a first extending strip 3211, a first protruding strip 3212, and a first interlocking groove 3213. The first extending strip 3211 extends and protrudes outwardly from an edge of the first interlocking portion 321 corresponding in position to the stair portion 23. The first protruding strip 3212 is formed at a position of the first interlocking portion 321 corresponding to the stair portion 23. The first interlocking groove 3213 is formed between the first protruding strip 3212 and the outside surface of the first interlocking portion 321. The second interlocking portion 322 is formed with a second extending strip 3221, a second protruding strip 3222, and a second interlocking groove 3223. The second extending strip 3221 extends and protrudes outwardly from a position adjacent to the bottom side of the second interlocking portion 322. The second protruding strip 3222 is formed at an end of the second extending strip 3221 and protrudes upwardly. The second interlocking groove 3223 is formed between the second extending strip 3221 and a position of the second interlocking portion 322 corresponding to the stair portion 23, as shown in FIG. 4.

The third interlocking portion 323 is formed with a third extending strip 3231, a third protruding strip 3232, and a third interlocking groove 3233. The third extending strip 3231 extends and protrudes outwardly from a position of the third interlocking portion 323 adjacent to the stair portion 23. The third protruding strip 3232 is formed at an end of the third extending strip 3221 and protrudes upwardly. The third interlocking groove 3233 is formed between the third protruding strip 3232 and the outside surface of the third interlocking portion 323. The fourth interlocking portion 324 is formed with a fourth extending strip 3241, a fourth protruding strip 3242, and a fourth interlocking groove 3243. The fourth extending strip 3241 extends and protrudes outwardly from a position of the fourth interlocking portion 324 adjacent to the stair portion 23. The fourth protruding strip 3242 is formed at an end of the fourth extending strip 3241 and protrudes downwardly. The fourth interlocking groove 3243 is formed between the fourth protruding strip 3242 and the outside surface of the fourth interlocking portion 324, as shown in FIG. 5. The height level of the fourth extending strip 3241 is a little higher than the height level of the third extending strip 3231.

Referring to FIG. 6 and FIG. 7, during the floor is paved, the long sides or short sides of two adjacent interlocking splicing floor panels 10 can be interlocked with each other. Two interlocking splicing floor panels 10 are defined as a first interlocking splicing floor panel 10A and a second interlocking splicing floor panel 10B for the description below, wherein the first interlocking splicing floor panel 10A and the second interlocking splicing floor panel 10B have the same base material main bodies 20 and the same edge sealing structures 30.

When the splice is performed to the long sides, the first extending strip 3211 of the first interlocking portion 321 of the first interlocking splicing floor panel 10A is inclinedly inserted into the second interlocking groove 3223 of the second interlocking portion 322 of the second interlocking splicing floor panel 10B. Then the first interlocking splicing floor panel 10A is pressed downwardly, so that the first interlocking splicing floor panel 10A becomes parallel to the second interlocking splicing floor panel 10B. In this way, the first extending strip 3211 of the first interlocking splicing floor panel 10A is accommodated in the second interlocking groove 3223 of the second interlocking splicing floor panel 10B and abutted against the outside surface of the second interlocking portion 322, and the first protruding strip 3212 is abutted against the second extending strip 3221. Meanwhile, the second protruding strip 3222 of the second interlocking splicing floor panel 10B is accommodated in the first interlocking groove 3213 of the first interlocking splicing floor panel 10A and abutted against the outside surface of the first interlocking portion 321, so that the long sides of the first interlocking splicing floor panel 10A and the second interlocking splicing floor panel 10B are fixedly engaged with each other.

When the splice is performed to the short sides, the first interlocking splicing floor panel 10A is combined to the second interlocking splicing floor panel 10B downwardly. The fourth protruding strip 3242 of the fourth interlocking portion 324 of the first interlocking splicing floor panel 10A is accommodated in the third interlocking groove 3233 of the third interlocking portion 323 of the second interlocking splicing floor panel 10B and abutted against the third extending strip 3231. Meanwhile, the third protruding strip 3232 of the second interlocking splicing floor panel 10B is accommodated in the fourth interlocking groove 3243 of the first interlocking splicing floor panel 10A and abutted against the fourth extending strip 3241, so that the short sides of the first interlocking splicing floor panel 10A and the second interlocking splicing floor panel 10B are fixedly engaged with each other.

In conclusion, the interlocking splicing floor panel 10 provided by the present invention at least has the following advantages when compared with the existing technique.

• • 1. In the interlocking splicing floor panel 10 of the present invention, the edge sealing structure 30 is disposed on the end surfaces 21 on the periphery of the base material main body 20. The edge sealing structure 30 provides interlocking and protecting functions, that disables moisture from entering the base material main body 20 through the end surfaces 21, so as to prevent the interlocking splicing floor panel 10 from absorbing moisture to cause expansion and deformation, thereby increasing the lifespan of the interlocking splicing floor panel 10.
  • 2. In the interlocking splicing floor panel 10 of the present invention, the rib portions 31 of the edge sealing structure 30 are embedded in the combining grooves 22 of the base material main body 20. Because the edge sealing structure 30 and the base material main body 20 are different in material, the combination thereof in the embedded manner can make them fixed to each other relatively more firmly. Even after the use for a long time, the edge sealing structure 30 will not separate from the end surfaces 21 of the base material main body 20.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
