Polishing apparatus for flat and bent vehicle panes

Abstract

The invention concerns a polishing apparatus ( 1 ), which has a very short handy and comfortable to handle construction with a very short length L. In order to reduce energy loss a direct vertical shaft ( 3 ) is used, which shaft ( 3 ) eccentrically drives the rotational head part ( 9 ). The special three legged support of the polishing apparatus ( 1 ) consists of the sanding or polishing disc ( 10 ) and two separately placed from each other adjustable support legs ( 11, 12 ). In this way flat and bent surfaces, such as vehicle panes, can be polished accurately and efficiently.

1 . Polishing apparatus for flat and bent surfaces of massive and laminated glass, specific flat and bent massive and laminated vehicle panes, wherein said polishing apparatus has a short horizontal construction length because of a vertical structure of the polishing apparatus, wherein the polishing apparatus includes a housing a handgrip for manual operation, an electric motor having a driving shaft and a rotation head part, the handgrip for manual operation of the polishing apparatus, the driving shaft with the electric motor and the rotation head part provided with a polishing or sanding disc at the bottom being situated in a vertical axle, being the driving shaft, wherein the housing of the polishing apparatus is provided with a three legged support. 
     
     
         2 . Polishing apparatus as in  claim 1 , wherein said threelegged support consists of a pair of support legs disposed at a distance with resect to each other and separately adjustable and as a third support the rotation head part with a polishing or sanding disc mounted thereon. 
     
     
         3 . Polishing apparatus as in  claim 1 , wherein said rotation head part with electric motor or battery motor is driven said driving shaft, which is vertically oriented. 
     
     
         4 . Polishing apparatus as in  claim 1 , wherein said rotation head part is driven pneumatically by said driving shaft. 
     
     
         5 . Polishing apparatus as in  claim 3 , wherein said electric motor or battery motor is applied to an electronic speed regulator in order to obtain a constant rotational speed of the polishing disc. 
     
     
         6 . Polishing apparatus as in  claim 1 , wherein said rotation head part is surrounded by a snap on conical tapered skirt part made of plastic in order to protect the fingers on the hand of the person using the polishing apparatus. 
     
     
         7 . Polishing apparatus as in  claim 6 , wherein said plastic consists of a carbon fiber-reinforced nylon.
