Hinge for a stove door

Abstract

The invention relates to a hinge for a stove door, comprising a housing ( 1 ) in which a plug-in part ( 2 ) is rotationally ( 10 ) mounted. In order to be able to easily influence the torque produced by the spring, a spring guide ( 3 ) which is loaded by a spring ( 6 ), preferably a pressure spring, is provided, said spring guide being fitted with roller ( 15 ) that is guided through a curved section ( 9 ) of the plug-in part ( 2 ).

         4 . The hinge according to one of the preceding claims, characterized in that the cam plate ( 9 ) has the inclination ( 16 ) that generates the required closing force in the closed position of the hinge.  
     
     
         5 . The hinge according to one of the preceding claims, characterized in that the cam plate ( 9 ) has a neutral section ( 18 ) with the hinge opened a specific distance, e.g., about 20°.  
     
     
         6 . The hinge according to one of the preceding claims, characterized in that the cam plate ( 9 ) is designed in such a way that the spring force generated by the cam plate progression essentially offsets the opening torque of the stove flap.  
     
     
         7 . The hinge according to one of the preceding claims, characterized in that the spring guide ( 3 ) is routed into the casing ( 1 ).  
     
     
         8 . The hinge according to  claim 7 , characterized in that the spring guide is routed into the casing ( 1 ) via a support ( 5 ), preferably a plastic support.  
     
     
         9 . The hinge according to one of the preceding claims, characterized in that the lever arm force (h) of the roll ( 15 ) can be varied relative to the pivot axis ( 10 ) of the plug-in part ( 2 ).  
     
     
         10 . The hinge according to one of the preceding claims, characterized in that the spring guide ( 3 ) has a guide pin ( 8 ) routed in an additional cam plate ( 4 ) of the casing ( 1 ).  
     
     
         11 . The hinge according to one of the preceding claims, characterized in that the pre-stress of the spring ( 6 ) can be varied.  
     
     
         12 . The hinge according to one of the preceding claims, characterized in that a stop ( 12 ) for the spring ( 6 ) can be adjusted, preferably by means of a nut.  
     
     
         13 . The hinge according to one of the preceding claims, characterized in that a locking part ( 25 ) is connected with the plug-in part ( 2 ).  
     
     
         14 . The hinge according to  claim 13 , characterized in that the locking part ( 25 ) can be pivoted ( 26 ).  
     
     
         15 . The hinge according to  claim 14 , characterized in that the pivot axis ( 26 ) of the locking part ( 25 ) is shiftable ( 27 ).  
     
     
         16 . The hinge according to one of  claims 13  to  15 , characterized in that the locking part ( 25 ) has a wedge ( 28 ).  
     
     
         17 . The hinge according to one of  claims 13  to  16 , characterized in that the locking part ( 25 ) has an actuating projection ( 31 ).  
     
     
         18 . The hinge according to one of  claims 13  to  17 , characterized in that the locking part ( 25 ′) has a face ( 41 ) that forms a stop surface.  
     
     
         19 . The hinge according to  claim 18 , characterized in that the distance between the face ( 41 ) and the pivot axis ( 26 ′) of the locking part ( 25 ′) becomes greater as the locking part ( 25 ′) increasingly pivots.  
     
     
         20 . The hinge according to  claim 18  or  19 , characterized in that the face ( 41 ) is curved.  
     
     
         21 . The hinge according to one of  claims 18  to  20 , characterized in that the face ( 41 ) has a circular arc contour, wherein the midpoint (m) of the circular arc ( 42 ) is spaced apart (a) from the midpoint (M) of the pivot axis ( 26 ′) of the locking part ( 25 ′).
