- Specific embodiments of the invention will be described below in detail with reference to the accompanying drawings, but the description of the embodiments is not a limitation of technical solution, and any form change rather than substantive change based on the concept of the invention should be regarded as the scope of protection of the invention.
- In the following description, all concepts involving orientations such as up, down, left, right, front and back all are relative to positional states of the drawings being described, which are intended to facilitate public understanding, and are not to be construed as special limitations of technical solutions provided by the invention.
- As illustrated in
FIG. 1 throughFIG. 4 , a mat for hidden-type splicing may include: amat body 1 and asplicing bottom base 2 each are constructed in a form of rectangular plate structure. Thesplicing bottom base 2 is fixedly connected to a surface of a downward side of themat body 1. Twoconvex parts 21 are respectively formed on one pair of adjacent right-angle sides of thesplicing bottom base 2. Twoconcave parts 22 are respectively formed on the other pair of right-angle sides of thesplicing bottom base 2, namely the right-angle sides symmetrical with the twoconvex parts 21 relative to a diagonal line of thesplicing bottom base 2. - Each the
convex part 21 has a convexpart connection surface 211, and the convexpart connection surface 211 is disposed corresponding to and being flush with a side edge of themat body 1. Multiple (i.e., more than one) outwardly convex splicingteeth 212 are protruded on the convexpart connection surface 211 outwards and arranged at intervals, adjacent two of the outwardlyconvex splicing teeth 212 have a splicingouter groove 213 formed therebetween, and the multiple outwardly convex splicingteeth 212 all protrude outside the side edge of themat body 1. - Each the
concave part 22 has a concavepart connection surface 221, and the concavepart connection surface 221 is disposed corresponding to and being flush with another side edge of themat body 1. Multiple inwardlyconcave splicing grooves 222 are recessed in the concavepart connection surface 221 inwards and arranged at intervals, the multiple inwardlyconcave splicing grooves 222 are matched with the multiple outwardly convex splicingteeth 212 in shape, adjacent two of the multiple inwardlyconcave splicing grooves 222 have a splicinginner tooth 223 formed therebetween, the splicinginner tooth 223 is matched with the splicingouter groove 213 in shape, and themat body 1 completely covers the twoconcave parts 22 of thesplicing bottom base 2 located therebelow from above. - Moreover, each the outwardly
convex splicing tooth 212 may be constructed in a form of inverted trapezoidal structure, with a portion of the outwardlyconvex splicing tooth 212 connected to the convexpart connection surface 211 constituting an outwardly convex splicingtooth bottom portion 2121 and another portion of the outwardlyconvex splicing tooth 212 away from the convexpart connection surface 211 constituting an outwardly convex splicing toothtop portion 2122. A length of the outwardly convex splicingtooth bottom portion 2121 is smaller than a length of the outwardly convex splicing toothtop portion 2122. It is noted that, the shape of the outwardlyconvex splicing tooth 212 is not limited to the illustrated embodiment, and can also be a T-shaped structure or a zigzag structure, and so on. - In a preferred embodiment, connections between the outwardly convex splicing
tooth bottom portion 2121 and the convexpart connection surface 211 and corresponding to two end portions in the lengthwise direction of the outwardly convex splicingtooth bottom portion 2121 are formed with outwardly convex splicing tooth connectionrounded corner portions 21211, respectively. Two end portions in the lengthwise direction of the outwardly convex splicing toothtop portion 2122 are formed with outwardly convex splicing tooth transitionrounded corner portions 21221, respectively. The outwardly convex splicing tooth connectionrounded corner portions 21211 and the outwardly convex splicing tooth transitionrounded corner portions 21221 can ensure smoothness of the whole outer edge surface of the outwardlyconvex splicing tooth 212, guarantee the safety of a user in manual splicing and avoid being scratched to thereby reflect humanization. - Please refer to
FIG. 1 andFIG. 2 again,multiple antiskid strips 11 are evenly protruded on a surface of an upward side of themat body 1. Themultiple antiskid strips 11 can increase a friction coefficient of the surface of the upward side of themat body 1, thereby improving anti-slip performance of themat body 1 and enhancing overall safety. - Furthermore, the
mat body 1 and thesplicing bottom base 2 may be made of an ethylene-vinylacetate copolymer (EVA) and be integrally formed (i.e., one-piece structure). The EVA has good flexibility, so that themat body 1 and thesplicing bottom base 2 have excellent shockproof and antiskid performance, and moreover have good compression resistance. - In an alternative embodiment, the
mat body 1 and thesplicing bottom base 2 are connected to form an integrated structure by using hot-pressing lamination or adhesive bonding. - Please refer to
FIG. 1 andFIG. 2 and especiallyFIG. 3 andFIG. 4 , a working principle of the technical solution provided by the illustrated embodiment of the invention will be briefly described as follows. Specifically, when multiple the mats according to the technical solution need to be spliced together, thesplicing bottom bases 2 of adjacent two of the mats are spliced, theconvex part 21 of onesplicing bottom base 2 is engaged with theconcave part 22 of the othersplicing bottom base 2, and the multiple outwardlyconvex splicing teeth 212 are matched and engaged with the corresponding inwardlyconcave splicing grooves 222, the multiple splicinginner teeth 223 are matched and engaged with the corresponding splicingouter grooves 213. Because theconvex part 21 can always be matched and engaged with the adjacentconcave part 22 hidden below themat body 1, after two mats are spliced together, themat body 1 of one of the two mats on one side can cover theconvex part 21 of the other one of the two mats on the other side from above, so that theconvex part 21 and the outwardly convex splicingteeth 212 will not be exposed outside, thereby realizing the splicing in a hidden manner. More specifically, please refer toFIG. 3 andFIG. 4 , four mats are assembled/spliced in a cross structure, theconvex part 21 at the left side of thesplicing bottom base 2 of the right top mat inFIG. 4 is matched and engaged together with theconcave part 22 at the right side of thesplicing bottom base 2 of the left top mat, theconcave part 22 at the bottom side of thespliced bottom base 2 of the right top mat and theconvex part 21 at the top side of thesplicing bottom base 2 of the right bottom mat are matched and engaged together, so that connecting parts of adjacent twosplicing bottom bases 2 of the four mats are fixedly engaged in a manner that theconvex part 21 and theconcave part 22 are spliced with each other, and as shown inFIG. 3 , theupper mat bodies 1 can completely cover and shield internally adjacent convex parts 21 (for splicing) of the foursplicing bottom bases 2; and by analogy, after multiple mats finish the splicing on a whole floor, theconvex parts 21 of the lowersplicing bottom bases 2 and the outwardly convex splicingteeth 212 are covered under themat bodies 1 and thus are not exposed outside, so that the front side is constituted byrectangular mat bodies 1, which is beautiful and elegant and convenient to clean. - In summary, the technical solution provided by the invention can make up for the defects in the prior art, successfully complete the task of the invention, and faithfully achieve the technical effects stated by the applicant in the above technical effect section.
