First of all, it should be pointed out that the meanings of terms, words and claims used in the present invention are not limited to their literal and ordinary. The meaning of the understanding also includes the meanings and concepts that are in turn consistent with the teachings of the present invention, since we as inventors should appropriately define the terms to best describe our invention. Therefore, the preferred embodiments of the present invention are set forth in the description and drawings, and are not intended to illustrate all of the technical features of the invention. We must realize that there are also a variety of equivalent programs or reforms that can replace our programs.

The present invention will now be described by way of preferred embodiments in order to enable those skilled in the art to practice the invention.

Since the present invention relates to a series of floorboards for a combined wooden floor which are matched to each other when combined into a combined wooden floor, the following description will be made by taking the combination of the floorboards into a combined wooden floor.

Referring to Figure 1, only two floorboards adjacent to the combined wooden floor are shown schematically (hereinafter, for the sake of clarity, the first floorboard 10 and the second floorboard 20 are referred to below).

The end portion of the first floor panel 10 and the second floor panel 20 are provided with a recess 11 extending from the end surface into the plate body of the first floor panel 10 in a direction parallel to the upper and lower surfaces of the floor. The groove 11 has an upper side surface 12 and a lower side surface 13 which are parallel to the upper and lower surfaces of the floor, and an end side surface 14 which connects the upper and lower side surfaces 12 and 13, and a recess is further formed at an appropriate position on the side surface 12. The recess 15 in the body of the first floor panel 10 is inserted. The recess 15 extends over the entire or partial upper side surface 12 in the direction of the parallel end side surface 14, and the surface of the recess 15 is formed in a spherical crown shape.

The end portion of the second floor panel 20 that abuts the first floor panel 10 is provided with a tongue 21 projecting from the end surface, the overall shape of the tongue 21 being complementary to the shape of the groove 11 of the first floor panel 10 It can be inserted into the groove 11. The tongue has an upper side surface 22 and a lower side surface 23 that are parallel to the upper and lower surfaces of the floor, and an end side surface 24 that connects the upper and lower side surfaces 22 and 23. On the side surface 22 of the second floor block tongue 21 corresponding to the position of the recess 15 on the first floor panel 10, a recess 25 recessed into the body of the second floor panel 20 is further formed. The recess 25 extends over the entire or partial upper side surface 11 in the direction of the parallel end side surface 24, and the surface of the recess 25 is formed in a cylindrical shape, and an adhesive material 40 is disposed between the combined portions of the adjacent floorboards.

The surface shape of the recess 15 and the recess 25 may be not only a spherical crown or a cylindrical shape, but may be other shapes such as a tapered shape.

The adhesive material 40 may be a polymer material such as rubber, plastic or fiber, or a synthetic modified material such as modified polyurethane, and its cross-sectional shape and size are designed to be recessed and second on the first floorboard 10 described above. The shape and size of the cavity formed by the depressions 25 on the floorboard 20 snap together.

Referring to FIG. 2 together, when assembling, the adhesive material 40 is placed in the recess 15 on the first floorboard 10 and/or the recess 25 on the second floorboard 20, and the tongue of the second floorboard 20 is placed. 21 is inserted into the groove 11 of the first floorboard 10, and the second floorboard 20 can be pushed straight into the recess 15 and the second ground on the first floorboard 10 due to the elastic deformability of the adhesive material 40. The depressions 25 on the panel 20 are joined together to form a cavity (not numbered), so that the adhesive material 40 recovers and is accommodated in the cavity, thus preventing the two depressions from being staggered in the horizontal direction, thereby ensuring The self-locking force between the first floorboard 10 and the second floorboard 20 stabilizes the splicing.

When disassembling, the tongue 21 of the second floorboard 20 is pulled out from the groove 11 of the first floorboard 10 with a slight force, so that the adhesive material 40 is elastically deformed again, so that the second floorboard ²⁰ can be A floor panel 10 is pulled out, which is easy to disassemble and can be reused after the first and second floor panels are removed. In addition, in order to install and disassemble, one of the recesses I ⁵ may be coated with an affinity agent and the other recessed The release agent is applied in 25, so that the adhesive material 40 can be stably bonded in the recess 15 coated with the affinity agent, and since one of the recesses ²⁵ is coated with a release agent, the tongue 21 is removed. It is easy to pull out from the groove 11.

In the above embodiment, the recesses 15, 25 are respectively disposed correspondingly on the upper side surface 12 of the first floorboard 10 and the upper side surface 11 of the second floorboard 20 adjacent thereto when assembled, it being understood that it may also be separately Correspondingly, they are disposed on the lower side surface 13 of the first floor panel 10 adjacent to the assembly and the lower side surface 23 of the second floor panel 20, as shown in FIG.

Moreover, although in the present invention, only a pair of adjacent recessed side surfaces are provided with a pair of corresponding recesses, it is understood that in order to enhance the stitching stability, a plurality of pairs of adjacent side surfaces may be provided. Corresponding recesses, for example, two or more recesses are respectively provided on the upper surfaces of the first and second floorboards, as shown in FIG. 4; or on two pairs of adjacent side surfaces (one pair of upper sides) A pair of corresponding recesses or the like are provided on each of the surface and the pair of lower side surfaces.

Referring to Fig. 5, a spring 26 may be fixedly disposed in the recess 25 of the second floor panel 20, and the adhesive material 40 is placed thereon during the splicing. Since the spring 26 is generally deformed by the same amount of force, the two pieces of the floor can be easily spliced together without requiring a large deformation of the adhesive material 40, and the flexibility of the adhesive material 40 is reduced. Any object having a certain slight deformation force can be restored. After the splicing is completed, the spring 26 is restored to deform, and the extruded adhesive material 40 is closely adhered to the inner wall of the recess 15 of the first floor.

It is easily conceivable that in order to avoid the trouble of placing the adhesive material 40 on the spring 26 when splicing, and the adhesive material 40 is easily misaligned with the spring 26 during splicing, the adhesive material 40 and the spring 26 can be used. Set to one, which saves the trouble of additional placement, and is not easy to splicing Position, splicing is easier, and the combined wooden floor after splicing is more secure.

It is easily conceivable that the spring can also be other elastic bodies which are more stretchable, such as rubber elastic bodies and the like.

The above embodiment only describes the case where the side surface of the floorboard is parallel to the edge of the floorboard, and it is also conceivable that the groove 11 has a trapezoidal shape such as a trapezoid, a triangle, or the like, as long as the groove 11 and the tongue 21 are formed. Matching, the other parts of the second floorboard 20 of the first floorboard 10 are also matched, we can design the two floorboards into any matching shape, and the grooves 11 and the tongues 21 can be designed into any shape. As shown in Fig. 6, the shape of the combined wooden floor is diversified to make it more visually pleasing, and only the difference of the groove 11 and the tongue 21 from the above embodiment is shown in Fig. 6, for two wooden floors. We can easily think of other shapes for the embodiment.

As another embodiment shown in FIG. 7, a recess 15 may be provided on a side surface (the upper side surface 12 in this embodiment) of the groove 11 of the first floor panel 10; and another adjacent ground The corresponding abutment surface of the tongue 23 of the panel (second floor panel 20) is not provided with a recess, but an elastic body is directly adhered and fixed at a suitable position of its corresponding side surface. The elastomer can be a tacky material 40. When assembled, due to the viscoelasticity, the adhesive material 40 is squeezed into the corresponding recesses 15 which are stabilized on the adjacent ground plates, preventing the two floor blocks from being horizontally staggered, thereby achieving a stable combination of the two floorboards. It will be understood that the position of the recess 15 and the adhesive material 40 may be interchanged, i.e., the recess is provided on the tongue 21, and the adhesive material 40 is adhesively fixed to the side surface of the recess 11.

In addition, as a preferred embodiment, the two joined floorboards may also be of the structure shown in FIG. The end portion of the first floor panel 10 that abuts the second floor panel 20 is provided with a recess 11 extending from the end surface into the plate body of the first floor panel 10 in a direction parallel to the upper and lower surfaces of the floor. The groove 11 has The upper side surface 12 and the lower side surface 13 parallel to the upper and lower surfaces of the floor and the end side surface 14 connecting the upper and lower side surfaces 12 and 13 are further formed with a concave first place at an appropriate position on the side surface 12. a recess 15 in the plate body of the plate 10, the recess 15 extending over the entire or partial upper side surface 12 in the direction of the parallel end side surface 14, wherein the recess 15 is fixed with a combination of a spring 26 and an adhesive material 40. One end of the protrusion protrudes from the recess 15 .

The end portion of the second floor panel 20 that abuts the first floor panel 10 is provided with a tongue 21 projecting from the end surface, the overall shape of the tongue 21 being complementary to the shape of the groove 11 of the first floor panel 10 It can be inserted into the groove 11. The tongue 21 has an upper side surface 11 and a lower side surface 23 which are parallel to the upper and lower surfaces of the floor, and an end side surface 24 which connects the upper and lower side surfaces 22 and 23.

On the side surface 22 of the second floor block tongue 21 corresponding to the position of the recess 15 on the first floor panel 10, a recess 25 recessed into the body of the second floor panel 20 is further formed. The recess 25 extends over the entire or partial upper side surface 22 in the direction of the parallel end side surface 24.

The surface shape of the recess 15 and the recess 25 may be spherical or cylindrical, or may be other shapes such as a tapered shape.

The adhesive material 40 may be a polymer material such as rubber, plastic or fiber, and a synthetic modified material such as a modified polyurethane, and its cross-sectional shape and size are designed to be different from the recess 15 and the second ground on the first floorboard 10 described above. The shape and size of the cavity formed by the depressions 25 on the panel 20 are fastened together.

Referring to FIG. 9 together, when assembling, the tongue 21 of the second floorboard 20 is inserted into the groove 11 of the first floorboard 10, and the second body can be inserted due to the strong elastic deformation capability of the combined body. Plate The recess 15 pushed all the way to the first floor panel 10 and the recess 25 on the second floor panel 20 are combined to form a cavity (not numbered) position, so that the combined body is deformed and accommodated in the cavity. In this way, the two depressions are prevented from being staggered in the horizontal direction, and the self-locking force between the first floorboard 10 and the second floorboard 20 is ensured, so that the splicing is stabilized. Because the spring has a strong deformation ability under the same force, the requirement of the other part of the combination is relatively low, and after the splicing is completed, the spring returns to the original shape, and the other part is pressed to make the two pieces. The plates are tightly coupled.

Further, for mounting and dismounting, a release agent is applied in the recess 25, and the tongue 21 is easily pulled out from the recess 11 when disassembled, since the spring 26 and the adhesive material 40 are joined as a combination, and no coating is required. Affinity, saving materials and reducing costs.

Based on the combined wooden floor in which the combined body is located on the side surface 12 of the first floorboard 10 and the upper side surface 22 of the tongue 21, it can be understood that we can also respectively provide the first floorboard 10 adjacent to each other at the time of assembly. The lower side surface 13 and the lower side surface 23 of the second floor panel 20 are on.

Moreover, in order to enhance the splicing stability, a plurality of pairs of corresponding recesses may be provided on a pair of adjacent side surfaces, for example, two or more on the upper surfaces of the first and second floorboards, respectively. The recess is provided with a pair of corresponding recesses or the like on each of a pair of adjacent side surfaces (a pair of upper side surfaces and a pair of lower side surfaces).

The above embodiment only describes the case where the side surface of the floorboard is parallel to the edge of the floorboard. It is also conceivable that the groove 11 has a trapezoidal shape such as a trapezoid, a triangle or the like, as long as the groove 11 and the tongue 21 are formed. Matching, the other pieces of the first floorboard 10 and the second floorboard 20 are also matched, we can design the first floorboard 10, the second floorboard 20 to have any matching shape, and also the grooves 11 and 榫The tongue 21 is designed in any shape to make the shape of the combined wooden floor diversified, making it visually more Have a sense of beauty.

The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It is considered as the scope of protection of the present invention.
