Pieced flooring that is made of foam material

Abstract

A pieced flooring includes at least four rectangular floorboards connected to one another. Each floorboard includes four edges each having a series of dovetail tenons laterally extending from the edges of each of the floorboards and a dovetail mortise defined in the floorboard between every two adjacent dovetail tenons for complementally receiving a corresponding one of the dovetail tenons of an adjacent floorboard. Each floorboard includes four corners each having a cutout defined in the floorboards such that an opening is centrally defined in the pieced flooring relative to the at least four floorboards that are connected to one another. At least one insertion is fixedly inserted into the opening and having an area greater than that of the opening to prevent the insertion from detaching from the pieced flooring and to promote the connection between the floorboards.

What is claimed is:  
     
         1 . A pieced flooring made of foam material and comprising: 
 at least four rectangular floorboards connected to one another, each floorboard including four edges each having a series of dovetail tenons laterally extending from each of the four edges of each of the floorboards and a dovetail mortise defined in the floorboard between every two adjacent dovetail tenons, the dovetail mortise provided to complementally receive a corresponding one of the series of dovetail tenons of an adjacent floorboard when the floorboards connected to one another, each floorboard including four corners each having a cutout defined in each of the floorboards such that an opening is centrally defined in the pieced flooring relative to the at least four floorboards that are connected to one another; and    at least one insertion fixedly inserted into the opening and having an area greater than that of the opening to prevent the insertion from detaching from the pieced flooring and to promote the connection between the floorboards.    
     
     
         2 . The pieced flooring as claimed in  claim 1 , wherein the opening and the insertion are rectangular for easily manufacturing.  
     
     
         3 . The pieced flooring as claimed in  claim 1 , wherein the opening and the insertion are designed as a rhombus for a vivid vision effect.  
     
     
         4 . The pieced flooring as claimed in  claim 1 , wherein the opening and the insertion are designed to have a round shape such that the insertion can be universally inserted into the opening without regarding the angle thereof.  
     
     
         5 . The pieced flooring as claimed in  claim 1 , wherein the opening and the insertion are designed to have a cross shape.  
     
     
         6 . The pieced flooring as claimed in  claim 5 , wherein the insertion includes four circle protrusions laterally extending therefrom and the shape of the opening corresponds to that of the insertion.
