Fixing device

Abstract

The invention relates to a fixing device for a cover of a drainage channel, road or yard gully or similar surface drainage devices, said cover being placed on an upper rim of a channel body, runoff box or similar body that can be embedded in the ground, with first fixing elements on the cover and second fixing elements on the body embeddable in the ground, such that the first fixing elements and the second fixing elements in each case can be brought into snapping engagement with one another to retain the cover on the body. The fixing device achieves a secure locking of the cover by simple manipulation, while simultaneously optimizing the cover's seating. To accomplish this the first fixing elements and/or the second fixing elements each comprise at least one damping section with a contact surface between the cover and the body embeddable in the ground, so that when locked in position the cover is spaced apart from the upper rim of the body.

1 . Fixing device for a cover of a surface drainage devices, comprising 
 said cover and a body adapted to be embedded in the ground and defining an upper rim on which said cover can be placed,    first fixing elements provided on said cover and second fixing elements provided on said body that can be brought into snapping engagement with one another to lock said cover to said body, and    at least one of said first fixing elements and said second fixing elements comprising at least one damping section defining a contact surface between said cover and said body such that when said cover is locked to said body said cover is spaced apart from said upper rim of said body.    
   
   
       2 . Fixing device according to  claim 1 , wherein said second fixing elements each comprise at least one said damping section that is constructed as a first protrusion with reference to the level of said upper rim such that said first protrusion extends in a direction perpendicular to a long direction of said upper rim.  
   
   
       3 . Fixing device according to  claim 1 , wherein said first fixing elements each comprise at least one said damping section that is constructed as a second protrusion with reference to the level of a surface of said cover that faces toward said body such that said second protrusion extends in a direction perpendicular to a long direction of said cover.  
   
   
       4 . Fixing device according to  claim 1 , wherein said first fixing elements and said second fixing elements are each formed so as to be captive respectively within said body and on said cover.  
   
   
       5 . Fixing device according to  claim 1 , wherein said first fixing elements and said second fixing elements are constructed so as to be substantially complementary to one another.  
   
   
       6 . Fixing device according to  claim 1 , wherein said first fixing elements are constructed as peg-like fixing elements.  
   
   
       7 . Fixing device according to  claim 6 , wherein said peg-shaped fixing elements each comprise at least one lug-like projection.  
   
   
       8 . Fixing device according to  claim 1 , wherein said second fixing elements each define a cavity adapted to receive said first fixing elements.  
   
   
       9 . Fixing device according to  claim 1 , wherein at least one of said first fixing elements and said the second fixing elements are elastically deformable.  
   
   
       10 . Fixing device according to  claim 1 , wherein at least one of said first fixing elements and said second fixing elements are made of at least one of a spring steel and an elastomer.  
   
   
       11 . Fixing device according to  claim 1 , wherein said second fixing elements each comprise at least one lug-like projection.  
   
   
       12 . Fixing device according to  claim 11 , wherein a first said lug-like projection is disposed so as to form a clamp with respect to a second said lug-like projection.  
   
   
       13 . Fixing device according to  claim 11 , wherein said at least one lug-like projection extends in a direction parallel to a long direction of the body.  
   
   
       14 . Fixing device according to  claim 11 , wherein said at least one lug-like projection extends perpendicular to a long direction of the body.  
   
   
       15 . Fixing device according to  claim 1 , wherein said first fixing elements each have a flat shape.  
   
   
       16 . Fixing device according to  claim 8 , wherein a height of said first fixing element perpendicular to a long direction of said body is dimensioned such that, when said cover is locked to said body, said first fixing element bears against a floor defined by said cavity of said second fixing element and said locked cover is spaced apart from said the upper rim of said the body.  
   
   
       17 . Fixing device according to  claim 1 , wherein said body defines opposing walls and said second fixing elements are each disposed in said opposite walls directly opposite to one another.  
   
   
       18 . Fixing device according to  claim 1 , wherein said body defines opposing walls and said second fixing elements are each disposed in said opposite walls so as to be offset from one another.  
   
   
       19 . Fixing device according to  claim 1 , wherein said second fixing elements each define at least one opening directed toward a middle of said body in order that contaminants that may have entered said second fixing elements are ejected into said body during insertion of said first fixing elements therein.
