Bed sheet set

Abstract

A bed sheet set includes a base unit, a cover unit and a connection unit. The base unit includes a bottom layer, a surrounding layer that extends upwardly from a periphery of the bottom layer, and a top layer that is connected to a top peripheral end of the surrounding layer. The cover unit is detachably mounted to the base unit, and includes a functional layer that is disposed over the top layer of the base unit, and a side layer that extends downwardly from a periphery of the functional layer. The connection unit includes a first connection component that is mounted to the surrounding layer, and a second connection component that is mounted to the side layer and that is detachably connected to the first connection component.

What is claimed is: 
     
         1 . A bed sheet set comprising:
 a base unit including a bottom layer, a surrounding layer that extends upwardly from a periphery of said bottom layer, and a top layer that is opposite to said bottom layer and that is connected to a top peripheral end of said surrounding layer;   a cover unit detachably mounted to said base unit, and including a functional layer that is disposed over said top layer of said base unit, and a side layer that extends downwardly from a periphery of said functional layer and that surrounds said surrounding layer of said base unit; and   a connection unit including a first connection component that is mounted to said surrounding layer of said base unit, and a second connection component that is mounted to said side layer of said cover unit and that is detachably connected to said first connection component.   
     
     
         2 . The bed sheet set as claimed in  claim 1 , wherein:
 said first connection component of said connection unit includes a first zipper chain;   said second connection component of said connection unit includes a second zipper chain; and   said connection unit further includes a zipper slider that is connected to one of said first and second zipper chains, and that is operable for linking and separating said first and second zipper chains.   
     
     
         3 . The bed sheet set as claimed in  claim 2 , wherein said first zipper chain is looped along said surrounding layer. 
     
     
         4 . The bed sheet set as claimed in  claim 1 , wherein said first connection component of said connection unit includes a male fastener, and said second connection component of said connection unit includes a female fastener. 
     
     
         5 . The bed sheet set as claimed in  claim 1 , wherein said first connection component of said connection unit includes a female fastener, and said second connection component of said connection unit includes a male fastener. 
     
     
         6 . The bed sheet set as claimed in  claim 1 , wherein said bottom layer of said base unit has an opening, and said base unit further includes an elastic band that is connected to said bottom layer around said opening. 
     
     
         7 . The bed sheet set as claimed in  claim 1 , wherein:
 said surrounding layer of said base unit has two opposite first side portions, and two opposite second side portions that are connected between said first side portions; and   said surrounding layer of said base unit is formed with a slit in one of said first side portions.   
     
     
         8 . The bed sheet set as claimed in  claim 7 , wherein said base unit further includes a zipper assembly that is connected to said one of said first side portions of said surrounding layer along said slit for opening and closing said slit. 
     
     
         9 . The bed sheet set as claimed in  claim 1 , wherein:
 said surrounding layer of said base unit has two opposite first side portions, and two opposite second side portions that are connected between said first side portions; and   said surrounding layer of said base unit is formed with a U-shaped slit that extends from one of said first side portions, through one of said second side portions, to the other one of said first side portions.   
     
     
         10 . The bed sheet set as claimed in  claim 9 , wherein said base unit further includes a zipper assembly that is connected to said surrounding layer of said base unit along said slit and that extends from said one of said first side portions, through said one of said second side portions, to said other one of first side portions for opening and closing said slit.
