Double-sided floorboard assembly

Abstract

A double-sided floorboard assembly includes one or multiple hook members affixed to a support frame bar on a bearing surface, and floor blocks arranged on the support frame bar. Each floor block has opposing front and rear side edges, opposing top and bottom surfaces respectively connected between the front and rear side edges, a first groove and a second groove located on the front side edge, a first rib formed on the front side edge between the first and second grooves, a third groove and a fourth groove located on the rear side edge. and a second rib formed on the rear side edge between the third and fourth grooves. The first rib of one floor block front is superimposed on the second rib of another floor block to define a first gap therebetween.

What is claimed is: 
     
         1 . A double-sided floorboard assembly, comprising:
 at least one hook member affixed to a support frame bar on a bearing surface; and   a plurality of floor blocks arranged on said support frame bar, each said floor block comprising opposing front side edge and rear side edge, opposing top surface and bottom surface respectively connected between said front side edge and said rear side edge, a first groove located on said front side edge, a second groove located on said front side edge at a bottom side relative to said first groove, a first rib formed on said front side edge between said first groove and said second groove, a third groove located on said rear side edge, a fourth groove located on said rear side edge at a bottom side relative to said third groove and a second rib formed on said rear side edge between said third groove and said fourth groove, the said first rib of one said floor block front being superimposed on the said second rib of another said floor block to define a first gap therebetween;   wherein when the said top surface of each said floor block faces upward, each said hook member is engaged in the said second groove of one said floor block and the said fourth groove of another said floor block; when the said top surface of each said floor block faces downward, each said hook member is engaged in the said first groove of one said floor block and the said third groove of another said floor block.   
     
     
         2 . The double-sided floorboard assembly as claimed in  claim 1 , wherein each said floor block further comprises a first top flange and a first bottom flange respectively formed on opposing top and bottom sides of said front side edge so that said first groove is disposed between said first top flange and said first rib and said second groove is disposed between said first bottom flange and said first rib, and a second top flange and a second bottom flange respectively formed on opposing top and bottom sides of said rear side edge so that said third groove is disposed between said second top flange and said second rib and said fourth groove is disposed between said second bottom flange and said second rib. 
     
     
         3 . The double-sided floorboard assembly as claimed in  claim 1 , wherein when the said top surface of each said floor block faces upward, the distance from the said second groove of one said floor block front side edge to said support frame bar is equal to the distance from the said fourth groove of another said floor block to said support frame bar; when the said top surface of each said floor block faces downward, the distance from the said first groove of one said floor block front side edge to said support frame bar is equal to the distance from the said third groove of another said floor block to said support frame bar. 
     
     
         4 . The double-sided floorboard assembly as claimed in  claim 1 , wherein said first rib of each said floor block comprises a first inclined side edge, said first inclined side edge extending obliquely from a top surface of the respective said first rib to an opposing bottom surface of the respective said first rib bottom surface; said second rib of each said floor block comprises a second inclined side edge, said second inclined side edge extending obliquely from a top surface of the respective said second rib to an opposing bottoms surface of the respective said second rib; the said first inclined side edge of the said first rib of one said floor block and the said second inclined side edge of the said second rib of another said floor block are superimposed on each other to define therebetween the said first gap. 
     
     
         5 . The double-sided floorboard assembly as claimed in  claim 4 , wherein the said first inclined side edge of the said first rib of one said floor block is disposed in parallel to the said second inclined side edge of the said second rib of another said floor block. 
     
     
         6 . The double-sided floorboard assembly as claimed in  claim 2 , wherein the said first top flange of one said floor block defines with the said second top flange of another said floor block a second gap therebetween; the said first bottom flange of one said floor block defines with the said second bottom flange of another said floor block a third gap therebetween; said first gap, said second gap and said third gap together form a flow channel. 
     
     
         7 . The double-sided floorboard assembly as claimed in  claim 1 , wherein said at least one hook member each comprises a mounting portion, two first extension portions and two second extension portions, said mounting portion being affixed to said support frame bar, said two first extension portions being respectively and vertically upwardly extended from two opposite sides of said mounting portion, said two second extension portions being respectively transversely extended from respective top ends of said two first extension portions in reversed direction, said two second extension portions being respectively engaged in the said second groove of one said floor block and the said fourth groove of another said floor block when the said top surface of each said floor block faces upward, said two second extension portions being respectively engaged in the said first groove of one said floor block and the said third groove of another said floor block when the said top surface of each said floor block faces downward. 
     
     
         8 . The double-sided floorboard assembly as claimed in  claim 1 , wherein the said top surface and bottom surface of each said floor block have different coefficients of friction.
