Rear end finisher and method of smoothing an outdoor surface

Abstract

The present invention relates to a rear finisher for smoothing an outer surface, which is attached in the forward direction behind a device for outdoor preparation and particularly for snow piste preparation. In order to allow a uniform appearance of the piste surface, the rear finisher has a guide device, which is applied so that the material to be prepared is guided in front of the bottom of the rear finisher and subsequently smoothed thereby. Furthermore, the present invention relates to a method for smoothing an outdoor surface, in which the outer surface to be smoothed is smoothed by two different oscillating means guided one after another on the outdoor surface.

1 . A rear finisher for smoothing an outer surface, which is attached as an auxiliary device in the forward. direction behind a device for outdoor preparation, particularly behind a device for snow piste preparation, comprising: 
 a guide device along a front side of the finisher, which is placed so that the material to be prepared is guided in front of the bottom of the rear finisher.    
   
   
       2 . The rear finisher according to  claim 1 , 
 wherein the guide device is a guide plate.    
   
   
       3 . The rear finisher according to  claim 1 , 
 wherein the guide device has a catch strip.    
   
   
       4 . The rear finisher according to  claim 1 , 
 wherein the rear finisher is elastically connected to the device for outdoor preparation.    
   
   
       5 . The rear finisher according to  claim 1 , 
 wherein the rear finisher is mounted on the device for outdoor preparation so it is capable of oscillation.    
   
   
       6 . The rear finisher according to  claim 5 , 
 wherein the mounting capable of oscillation has a spring element.    
   
   
       7 . The rear finisher according to  claim 1 , 
 wherein the device for outdoor preparation connected to the rear finisher is a vibration plate.    
   
   
       8 . The rear finisher according to  claim 7 , 
 wherein the vibrations of the vibration plate are transmitted to the rear finisher by support elements.    
   
   
       9 . The rear finisher according to  claim 1 , 
 wherein the rear finisher has means, which apply vibrations to the rear finisher independently of the device for outdoor preparation.    
   
   
       10 . The rear finisher according to  claim 7 , 
 wherein the oscillations of the vibration plate are transmitted damped to the rear finisher.    
   
   
       11 . The rear finisher according to  claim 7 , 
 wherein the oscillation behavior of the rear finisher is set by ballasting.    
   
   
       12 . The rear finisher according to  claim 7 , 
 wherein the oscillation behavior of the rear finisher is set by tuning the mounting capable of oscillation.    
   
   
       13 . The rear finisher according to  claim 7 , 
 wherein the mounting capable of oscillation is selected so that the rear finisher oscillates in its natural frequency.    
   
   
       14 . The rear finisher according to  claim 7 , 
 wherein the ballasting is selected so that the rear finisher oscillates in its natural frequency.    
   
   
       15 . A method for smoothing an outer surface, comprising: 
 smoothing the outdoor surface to be smoothed using two different oscillating means guided one after another on the outdoor surface.
