Toilet seat and a toilet cover assembly with integrated hinge eyes

Abstract

A toilet seat and a toilet cover assembly comprising such as toilet seat and an associated cover, in which the seat and the cover each are/is formed integrally with hinge eyes ( 6,7 ) at their rear edges for being pivotally mounted on a toilet bowl ( 9 ) about a horizontal axis. Both the seat ( 1 ) and the cover ( 2 ) are made by compression moulding in a mould consisting of a first mould part and a second mould part, a first surface being formed of the first mould part and a second surface being formed of the second mould part, a seat parting line ( 3 ) and a cover parting line ( 4 ) provided along the periphery defining the transition between the first face and the second face. The seat parting line ( 3 ) and the cover parting line ( 4 ) both extend continuously and without sharp concave notches such that flashes or fins formed during the moulding process may be ground off without removing additional moulding material.

1 . A toilet seat ( 1 ) being integrally formed with hinge eyes ( 6 ) at its rear edge for being pivotally mounted on a toilet bowl ( 9 ) about a horizontal axis, said toilet seat ( 1 ) being made in a moulding process, in particular in a compression moulding process, in a mould consisting of a first mould part and a second mould part, a first surface ( 8 ) of the seat being formed of the first mould part and defining the seating area, a second surface of the seat being moulded of the second mould part, and a seat parting line ( 3 ) along the outer periphery of the seat and along the periphery of the inner opening of the seat defining the transition between the first surface and the second surface, characterised in that the hinge eyes ( 6 ) are provided in areas of the seat ( 1 ) which are spaced apart from the seat parting line ( 3 ), said seat parting line ( 3 ) extends continuously and without sharp, concave notches such that the flashes or fins formed during the moulding process may be ground off without removing additional moulding material.  
     
     
         2 . A toilet seat according to  claim 1 , characterised in that the seat parting line ( 3 ) has nowhere a concave curvature having a radius of curvature (R 1 ) of less than 10 mm, preferably of less than 15 mm, when measured perpendicular to the seat material surface.  
     
     
         3 . A toilet seat according to  claim 1  or  2 , characterised in that the seat parting line ( 3 ) has nowhere a convex curvature having a radius of curvature (R 2 ) of less than 5 mm, preferably of less than 8 mm, when measured perpendicular to the seat material surface.  
     
     
         4 . A toilet seat according to one of the claims  1 - 3 , characterised in that the hinge eyes ( 6 ) are provided as apertures in part areas extending substantially perpendicular to the main plane of the seat.  
     
     
         5 . A toilet cover assembly comprising a seat ( 1 ) according to one of the claims  1 - 4  and a cover ( 2 ), said cover being formed integrally with hinge eyes ( 7 ) adjacent its rear edge for being pivotally mounted on a toilet bowl about a horizontal axis, and further being made in a moulding process, in particular in a compression moulding process, in a mould consisting of a first mould part and a second mould part, a first surface ( 16 ) of the cover being formed of the first mould part and facing the seat ( 1 ) in the lowered position of the cover ( 2 ) and a second surface of the cover being formed of the second mould part, a cover parting line ( 4 ) provided along the outer periphery of the cover defining the transition between the first face and the second face, characterised in that cover parting line ( 4 ) extends continuously and without sharp concave notches such that flashes or fins formed during the moulding process may be ground off without removing additional moulding material.  
     
     
         6 . A toilet cover assembly according to  claim 5 , in which the cover parting line ( 4 ) has nowhere a concave curvature having a radius of curvature (R 3 ) of less than 10 mm; preferably of less than 15 mm, when measured perpendicular to the seat material surface.  
     
     
         7 . A toilet cover assembly according to  claim 5  or  6 , characterised in that the cover parting line ( 4 ) has nowhere a convex curvature having a radius of curvature (R 4 ) of less than 5 mm, preferably of less than 8 mm, when measured perpendicular to the seat material surface.  
     
     
         8 . A toilet seat assembly according to one of the claims  5 - 7 , characterised in that the cover hinge eyes are shaped as blind holes ( 7 ) extending into the cover ( 2 ) from the first face ( 16 ) of the cover.  
     
     
         9 . A toilet seat assembly according to, one of the claims  5 - 7 , characterized in that the cover hinge eyes are shaped as through holes extending from the first face ( 16 ) of the cover ( 2 ) to the second face of the cover.
