Water draining plug

Abstract

A water draining plug which can be inserted in a hole in a horizontal wall, comprising a peg-like element having a head, whose dimensions are greater than the diameter of said hole and which is provided with a plurality of apertures for the passage of water, a shank extending downward from said head, and a helical formation extending radially from a portion of said shank; and a cup-like cover having a lower wall connected to a lower end of said shank, a discharge aperture in said lower wall, a side wall in contact with outer edges of said helical formation and an upper edge which can contact the lower surface of said wall around said hole.

1 . A water draining plug which can be inserted in a hole (H) in a horizontal wall (W), comprising:
 a peg-like element ( 12 ) having a head ( 16 ), whose dimensions are greater than the diameter of said hole (H) and which is provided with a plurality of apertures ( 18 ) for the passage of water, a shank ( 22 ) extending downward from said head ( 16 ), and a helical formation ( 24 ) extending radially from a portion of said shank ( 22 ); and   a cup-like cover ( 14 ) having a lower wall ( 30 ) connected to a lower end of said shank ( 22 ), a discharge aperture ( 36 ) in said lower wall ( 30 ) a side wall ( 32 ) in contact with outer edges of said helical formation ( 24 ) and an upper edge ( 34 ) which can contact the lower surface of said wall (W) around said hole (H).   
     
     
         2 . The plug as claimed in  claim 1 , wherein said head ( 16 ) comprises a plurality of arms ( 20 ) spaced apart from each other in the angular direction and defining between themselves said apertures ( 18 ) for the passage of water. 
     
     
         3 . The plug as claimed in  claim 2 , wherein said arms ( 20 ) are resiliently flexible. 
     
     
         4 . The plug as claimed in  claim 3 , wherein said arms ( 20 ) are inclined relative to a plane orthogonal to a longitudinal axis (A) of said peg-like element ( 12 ). 
     
     
         5 . The plug as claimed in  claim 1 , wherein said shank ( 22 ) has a groove ( 24 ) at its lower end which engages said discharge aperture ( 36 ) formed in said base wall ( 30 ) of said cover ( 14 ). 
     
     
         6 . The plug as claimed in  claim 5 , wherein an open hole is formed between said discharge aperture ( 36 ) of the base wall ( 30 ) of said cover ( 14 ) and a chamfer ( 38 ) formed at a lower end of said shank ( 22 ). 
     
     
         7 . The plug as claimed in  claim 2 , wherein the outer ends of said arms ( 20 ) are slightly lower than the upper edge ( 34 ) of said cover ( 14 ).
