Urinal anti-splashback device

Abstract

An insert for a urinal configured in use to prevent splashback, the insert comprising a central portion for extending across a drain of a urinal, and a plurality of spaced apart outer portions extending radially outwardly from the central portion and defining gaps between adjacent outer portions, in which the central portion and each outer portion comprises: a plurality of spaced apart pebble features, in which each pebble feature comprises a mound having a domed surface; and a plurality of spacers, in which each spacer adjoins adjacent pebble features in a configuration such that each pebble feature is adjoined to at least one adjacent pebble feature, and in which openings providing a fluid flowpath are defined between the pebble features and the spacers.

1 . An insert for a urinal configured in use to prevent splashback, the insert comprising a central portion for extending across a drain of a urinal, and a plurality of spaced apart outer portions extending radially outwardly from the central portion and defining gaps between adjacent outer portions, in which the central portion and each outer portion comprises:
 a plurality of spaced apart pebble features, in which each pebble feature comprises a mound having a domed surface; and   a plurality of spacers, in which each spacer adjoins adjacent pebble features in a configuration such that each pebble feature is adjoined to at least one adjacent pebble feature, and in which openings providing a fluid flowpath are defined between the pebble features and the spacers.   
     
     
         2 . An insert as claimed in  claim 1 , in which a V-shaped gap is provided between adjacent outer portions. 
     
     
         3 . An insert as claimed in either of  claims 1 and 2 , in which the central portion has a substantially circular cross-section. 
     
     
         4 . An insert as claimed in any one of  claims 1 to 3 , in which each outer portion is substantially triangular, or truncated triangular, in shape. 
     
     
         5 . An insert as claimed in  any preceding claim , in which the plurality of spaced apart pebble features comprises pebble features having at least two different heights and/or diameters. 
     
     
         6 . An insert as claimed in any one of  claims 1 to 5 , in which the height of the pebble features of the central portion (as defined between the upper and lower surfaces thereof) is greater than the height of the pebble features of the outer portions. 
     
     
         7 . An insert as claimed in  any preceding claim , in which the insert is composed of injection moulded plastic. 
     
     
         8 . An insert as claimed in  claim 6 , in which the injection moulded plastic is EVA a rubberised plastic. 
     
     
         9 . An insert claimed in  any preceding claim , further comprising fragrance oil. 
     
     
         10 . An insert as claimed in  any preceding claim , in which the pebble features are located at or adjacent an upper surface of the insert. 
     
     
         11 . An insert as claimed in  any preceding claim , further comprising an opening or compartment for receiving and storing an enzyme cake. 
     
     
         12 . An insert as claimed in  claim 11 , in which the opening or compartment is located at or adjacent a lower surface of the insert. 
     
     
         13 . An insert as claimed in  any preceding claim , further comprising an edge definer for defining the edge of the configuration of pebble features. 
     
     
         14 . An insert as claimed in  any preceding claim , comprising four spaced apart outer portions. 
     
     
         15 . An insert for a urinal configured in use to prevent splashback, the insert comprising:
 a domed central portion for extending across a drain of a urinal, in which the central portion comprises:
 a plurality of spaced apart pebble features, in which each pebble feature comprises a mound having a domed surface; and 
 a plurality of spacers, in which each spacer adjoins adjacent pebble features in a configuration such that each pebble feature is adjoined to at least one adjacent pebble feature, and in which openings providing a fluid flowpath are defined between the pebble features and the spacers; and 
   a neck portion configured in use to be received within a drain of a urinal.   
     
     
         16 . An insert as claimed in  claim 15 , in which the plurality of spaced apart pebble features comprises pebble features having at least two different heights and/or diameters. 
     
     
         17 . An insert as claimed in  claim 16 , in which the height of the pebble features located at or adjacent the centre of the domed central portion (as defined between the upper and lower surfaces thereof) is greater than the height of the pebble features at or adjacent an edge of the domed central portion. 
     
     
         18 . An insert as claimed in  any preceding claim , in which the insert is composed of injection moulded plastic. 
     
     
         19 . An insert as claimed in  claim 18 , in which the injection moulded plastic is EVA a rubberised plastic. 
     
     
         20 . An insert claimed in  any preceding claim , further comprising fragrance oil. 
     
     
         21 . An insert as claimed in  any preceding claim , in which the pebble features are located at or adjacent an upper surface of the insert. 
     
     
         22 . An insert as claimed in  any preceding claim , further comprising an opening or compartment for receiving and storing an enzyme cake. 
     
     
         23 . An insert as claimed in  claim 22 , in which the opening or compartment is located at or adjacent a lower surface of the insert. 
     
     
         24 . An insert as claimed in  any preceding claim , further comprising an edge definer for defining the edge of the configuration of pebble features.
