Liquid-filled damper for a shock-sensitive apparatus

Abstract

The invention relates to a liquid-filled damper for a shock-sensitive apparatus, comprising a base part and an elastic cover part. It is an object of the invention to provide a liquid-filled damper and a method of manufacturing such a damper, which can be manufactured and mounted in an easier and more reliable way. To this end, the liquid-filled damper comprises an integrated fixation element, and the base part and the integrated fixation element are connected by means of the elastic cover part.

1 . A liquid-filled damper for a shock-sensitive apparatus, comprising a base part and an elastic cover part, characterized in that the liquid-filled damper comprises an integrated fixation element, and in that the base part and the integrated fixation element are connected by means of the elastic cover part.  
     
     
         2 . A liquid-filled damper as claimed in  claim 1 , characterized in that the base part and the integrated fixation element are made of a substantially non-elastic synthetic material, and in that the elastic cover part is made of an elastomer, particularly an elastic synthetic material.  
     
     
         3 . A liquid-filled damper as claimed in  claim 1 , characterized in that the base part is made of a substantially non-elastic synthetic material, and in that the elastic cover part and the integrated fixation element are made of an elastomer, particularly rubber.  
     
     
         4 . A liquid-filled damper as claimed in  claim 1 , characterized in that the fixation element is implemented as a fixation pin.  
     
     
         5 . A liquid-filled damper as claimed in  claim 4 , characterized in that the fixation pin is connected to the elastic cover part in an axial central area.  
     
     
         6 . A liquid-filled damper as claimed in  claim 1 , characterized in that the liquid is a viscous material, particularly oil.  
     
     
         7 . An electronic apparatus comprising a shock-sensitive unit accommodated in a housing, which unit is coupled to the housing by means of at least a liquid-filled damper, the damper having a base part and an elastic cover part, characterized in that the damper comprises an integrated fixation element, in that the base part and the integrated fixation element are connected by means of the elastic cover part, in that either the integrated fixation element is fixed to the housing and the base part is fixed to the shock-sensitive unit, or in that the housing.  
     
     
         8 . An electronic apparatus as claimed in  claim 7 , characterized in that the apparatus is an apparatus for reading information stored on an optical record carrier and/or for writing information on an optical record carrier, particularly a CD/DVD apparatus.  
     
     
         9 . An electronic apparatus as claimed in  claim 7 , characterized in that the apparatus is adapted to be built into a vehicle.  
     
     
         10 . A method of manufacturing a liquid-filled damper, characterized by the steps of 
 molding a base part and a fixation element from a substantially non-elastic synthetic material, and    molding a cover part from an elastic synthetic material, the base part and the fixation element being connected together by means of the elastic cover part.
