Guard device

Abstract

A guard device includes at least one basic element, at least one fastening element, and at least one guard anti-twist device. The at least one guard anti-twist device includes at least one braking element that, in at least one operating state of a portable power tool, is configured at least essentially at least to frictionally anti-twist lock the at least one basic element relative to the portable power tool. The at least one guard anti-twist device also includes at least one actuating unit configured to displace the at least one braking element. The at least one actuating unit includes at least one screwing element.

What is claimed is: 
     
         1 . A guard device, comprising:
 at least one basic element;   at least one fastening element; and   at least one guard anti-twist device, including:
 at least one braking element that, in at least one operating state of a portable power tool, is configured at least essentially at least to frictionally anti-twist lock the at least one basic element relative to the portable power tool; and 
 at least one actuating unit configured to displace the at least one braking element, the at least one actuating unit including at least one screwing element. 
   
     
     
         2 . The guard device according to  claim 1 , wherein the at least one screwing element is configured to act, at least partly in a radial direction, on the at least one braking element. 
     
     
         3 . The guard device according to  claim 1 , wherein the at least one screwing element is configured to at least partially directly contact the at least one braking element. 
     
     
         4 . The guard device according to  claim 1 , wherein the at least one guard anti-twist device includes at least one receiving element configured to correspond with the at least one screwing element. 
     
     
         5 . The guard device according to  claim 4 , wherein the at least one receiving element at least partially includes an internal thread. 
     
     
         6 . The guard device according to  claim 4 , wherein the at least one receiving element is formed at least partially by a screw nut. 
     
     
         7 . The guard device according to  claim 4 , wherein the at least one receiving element is connected at least partially fixedly to the at least one fastening element. 
     
     
         8 . The guard device according to  claim 1 , wherein the at least one guard anti-twist device includes at least one bearing unit configured to support the at least one braking element, at least in a braking state, movably relative to the at least one basic element. 
     
     
         9 . The guard device according to  claim 8 , wherein the at least one bearing unit is configured to support the at least one braking element such that the at least one braking element is tiltable about at least one axis. 
     
     
         10 . A system, including:
 at least one portable power tool; and   at least one guard device, including:
 at least one basic element; 
 at least one fastening element; and 
 at least one guard anti-twist device, including:
 at least one braking element that, in at least one operating state of a portable power tool, is configured at least essentially at least to frictionally anti-twist lock the at least one basic element relative to the portable power tool; and 
 at least one actuating unit configured to displace the at least one braking element, the at least one actuating unit including at least one screwing element.
