Outdoor combination floor

Abstract

An outdoor floor covering includes a plurality of planks, a plurality of bases, and at least a fastening element. A positioning portion of each base is slidably disposed in a sliding groove of each plank. Adjacent ones of first sidewall surfaces of the bases are engaged with each other through engaging portions. Adjacent ones of second sidewall surfaces of the bases abut against each other through protruding and dent portions. At least a fastening element is engaged and connected between adjacent ones of the second sidewall surfaces of the bases. Hence, the outdoor floor covering of the present invention enables quick assembly and prevents the planks and bases from undergoing displacement horizontally or vertically. Accordingly, the outdoor floor covering is quick and convenient to lay, exhibits satisfactory structural stability, and enhances pedestrian safety.

What is claimed is: 
     
         1 . An outdoor floor covering, comprising:
 a plurality of planks, wherein a sliding groove is disposed at a bottom of each said plank;   a plurality of bases each having a top surface, a bottom surface, two opposing first sidewall surfaces, two opposing second sidewall surfaces, and an engaging groove, wherein the top surface has a positioning portion penetrating the sliding groove, wherein the first sidewall surfaces each have a first engaging portion and a second engaging portion, wherein adjacent ones of the first sidewall surfaces of the bases are engaged with each other through the first and second engaging portions, wherein the second sidewall surfaces each have a protruding portion, a dent portion, and a snap-engaging portion, wherein adjacent ones of the second sidewall surfaces of the bases mesh with each other through the protruding and dent portions, wherein the snap-engaging portions are adjacent to the protruding and dent portions, respectively, and each have a ramp, wherein the engaging grooves are each adjacent to a corresponding one of the dent portions and formed between a terminal end of the dent portion and the snap-engaging portions; and   at least a fastening element engaged and connected between adjacent ones of the second sidewalls of the bases, wherein at least a said fastening element has a bottom wall, two endwalls, and a hook-engaging wall, wherein the endwalls extend from two ends of the bottom wall and toward the snap-engaging portions of the bases and each have a ramp, wherein the ramps of the endwalls abut against and align with the ramps of the snap-engaging portions, respectively, wherein the hook-engaging wall is disposed between the endwalls, extends from a side of the bottom wall toward the protruding and dent portions of the bases, and forms a hook portion at a terminal end of the hook-engaging wall, wherein the hook portion is hook-engaged with the engaging groove, wherein the bottom wall, the endwalls, and the hook-engaging wall define a snap-engaging slot for receiving the snap-engaging portions of the planks.   
     
     
         2 . The outdoor floor covering of  claim 1 , wherein a through hole is disposed at each said base, and the planks are each fixed to a corresponding one of the bases through a fixing element passing through the through hole. 
     
     
         3 . The outdoor floor covering of  claim 1 , wherein an identification area is defined on a bottom wall of at least a said fastening element and disposed between one of the endwalls and the hook-engaging wall. 
     
     
         4 . The outdoor floor covering of  claim 3 , wherein the identification area of at least a said fastening element is a countersunk hole penetrable by a screw. 
     
     
         5 . The outdoor floor covering of  claim 1 , wherein one of the snap-engaging portions of each said base has two said ramps, and a hook-engaging wall of at least a said fastening element has a ramp, wherein two said ramps of the snap-engaging portions abut against and align with the ramps of one of the endwalls of each said fastening element and the ramp of the hook-engaging wall. 
     
     
         6 . The outdoor floor covering of  claim 1 , wherein the ramps of the snap-engaging portions of each said base each have a plurality of driven positioning serrate portions, and the ramps of the two endwalls of at least a fastening element each have a plurality of driving positioning serrate portions, wherein the driving and driven positioning serrate portions mesh with each other. 
     
     
         7 . The outdoor floor covering of  claim 1 , wherein a pad extends from one of the snap-engaging portions of the bases and is positioned proximate to the bottom surface of the base. 
     
     
         8 . The outdoor floor covering of  claim 1 , wherein a plurality of drain holes is disposed at each or one of the protruding and dent portions of the bases. 
     
     
         9 . The outdoor floor covering of  claim 1 , wherein the sliding groove of each said plank is an T-shaped receiving space comprising a narrow passage and a wide chamber, whereas the positioning portion of each said base comprises a vertical segment and a horizontal segment, wherein the vertical segment has an end connected to the top surface of the base and has another end connected to the horizontal segment, wherein the vertical segment and the horizontal segment are received in the narrow passage and the wide chamber, respectively. 
     
     
         10 . The outdoor floor covering of  claim 1 , wherein a reinforcing rib is disposed and defined by and between the bottom wall, the hook-engaging wall, and the hook portion of at least a said fastening element.
