Drain cover

Abstract

A drain cover is adapted for covering a drain device which is mounted to a drain carrier. The drain cover includes a grid member and a weight member. The grid member has a coupling portion and a grid portion that is adapted to be disposed on the drain carrier and to surround the drain device. The grid portion is flexible, cooperates with the coupling portion to define a receiving space, and is formed with a plurality of grid holes. At least one of the coupling portion and the grid portion has a thermochromic section that is capable of changing colors due to a change in temperature. The weight member is coupled to the coupling portion of the grid member, and is adapted to be disposed over the valve of the drain device.

What is claimed is: 
     
         1 . A drain cover adapted for covering a drain device, the drain device being mounted to a drain carrier and having a water outlet and a valve that covers openably the water outlet, said drain cover comprising:
 a grid member having a coupling portion, and a grid portion that is adapted to be disposed on the drain carrier and surround the drain device, said grid portion being flexible, surrounding and being coupled to said coupling portion, cooperating with said coupling portion to define a receiving space, and being formed with a plurality of grid holes that are in spatial communication with said receiving space and the external environment, at least one of said coupling portion and said grid portion having a thermochromic section that is capable of changing colors due to a change in temperature; and   a weight member coupled to said coupling portion of said grid member and adapted to be disposed over the valve of the drain device.   
     
     
         2 . The drain cover as claimed in  claim 1 , wherein:
 said coupling portion is formed with a through hole; and   said weight member engages said through hole.   
     
     
         3 . The drain cover as claimed in  claim 2 , wherein said weight member has:
 a cover portion that is exposed from said grid member; and   a weight portion that is connected to said cover portion and that engages said through hole.   
     
     
         4 . The drain cover as claimed in  claim 3 , wherein said weight portion of said weight member is made of metal. 
     
     
         5 . The drain cover as claimed in  claim 4 , wherein said cover portion and said weight portion of said weight member are molded as one piece. 
     
     
         6 . The drain cover as claimed in  claim 4 , wherein said cover portion of said weight member is made of a plastic material. 
     
     
         7 . The drain cover as claimed in  claim 6 , wherein said cover portion is connected removably to said weight portion. 
     
     
         8 . The drain cover as claimed in  claim 7 , wherein said cover portion and said weight portion cooperatively define an air chamber therebetween. 
     
     
         9 . The drain cover as claimed in  claim 1 , wherein said grid member is made of a composition having a base material that is selected from a group consisting of silicon rubber and plastic, and a thermochromic material that is disposed in said thermochromic section. 
     
     
         10 . The drain cover as claimed in  claim 9 , wherein said thermochromic material is a thermochromic ink coated on said thermochromic section of said grid portion. 
     
     
         11 . The drain cover as claimed in  claim 1 , wherein said grid portion of said grid member further has a surrounding peripheral section that is connected to said thermochromic section and that is adapted to be placed on the drain carrier. 
     
     
         12 . The drain cover as claimed in  claim 1 , wherein said weight member is enclosed in said coupling portion of said grid member. 
     
     
         13 . The drain cover as claimed in  claim 12 , wherein said weight member is made of metal.
