       13 . A compact drain assembly for sinks and the like, comprising at least one drain duct which can be coupled hermetically at a drain hole which is defined at least at the lateral surface of a sink and has at least one portion which is at the same level as, or lower than, the bottom of said sink, a closure element for closing said drain duct being further provided which affects said at least one drain duct. 
   
   
       14 . A drain assembly for sinks and the like, comprising at least one drain duct which can be coupled hermetically at a drain hole provided in said sink, an element for closing the drain being further provided which affects said at least one drain duct, a safety overflow being provided which is arranged downstream of said drain closure element. 
   
   
       15 . The drain assembly according to  claim 13 , further comprising a bowl element which can be applied hermetically at a lateral portion of at least one bowl of said sink. 
   
   
       16 . The drain assembly according to  claim 15 , further comprising, on said bowl element, in case of a two-bowl sink, two drain ducts which are separated by a dividing wall arranged in the region located between the two bowls of a sink. 
   
   
       17 . The drain assembly according to  claim 13 , further comprising a grille which is arranged at said drain hole and only acts as a barrier. 
   
   
       18 . The drain assembly according to  claim 13 , wherein said closure element comprises a flow control element with a flap which can rotate about its own axis and is arranged so as to control the respective drain duct. 
   
   
       19 . The drain assembly according to  claim 18 , wherein said flap-like flow control element comprises a radially protruding pin, which is connected to a gear which meshes with a rack which can slide due to the action of a cable which can be actuated by a control knob which can be located on said sink. 
   
   
       20 . The drain assembly according to  claim 14 , wherein said safety overflow has an height-adjustable level. 
   
   
       21 . The drain assembly according to  claim 20 , wherein said safety overflow is defined in a chamber which is positioned laterally with respect to said bowl and is provided with a level control partition which can move in order to vary the useful height which determines the water overflow level. 
   
   
       22 . The drain assembly according to  claim 21 , wherein said level control partition can slide hermetically within guides defined at the dividing wall between the two bowls of a sink. 
   
   
       23 . The drain assembly according to  claim 22 , comprising actuation means for positioning said level control partition. 
   
   
       24 . The drain assembly according to  claim 23 , wherein said actuation means for positioning the level control partition comprise a linear set of teeth, which is provided on said partition and is engaged by an actuation gear, which is arranged on a shaft which is associated with a pinion which is connected to a detent system which can be actuated by means of a cable connected to a knob.
