Power tool, particularly a hand-held power tool

Abstract

The invention relates to a power tool, comprising a protective guard, and a clamping band to be positioned about a clamping collar for attaching a protective guard to the clamping collar of the power tool. The clamping band is tensioned by a fastening device associated with the protective guard by way of a screw. A section of the clamping band is designed as a pivoting section, which is held at an adjoining section of the clamping band in an articulating manner.

         18 . A power tool, in particular a hand-held power tool such as an angle grinder, having a protective guard which fastens to a clamping collar of the power tool by means of a clamping band which is placed around the clamping collar and clamped thereto by means of an actuating element and which has a pivoting section that is acted on by the actuating element and that is able to pivot into a radially pivoted-out position. 
     
     
         19 . The power tool as recited in  claim 18 , wherein the clamping collar of the power tool has a denticulation extending in a circumference direction which denticulation is engaged by a locking element of the pivoting section in a locked position. 
     
     
         20 . The power tool as recited in  claim 19 , wherein a circumferential groove is provided on the clamping collar. 
     
     
         21 . The power tool as recited in  claim 20 , wherein tooth-shaped recesses, which extend in an axial direction on the clamping collar starting from the circumferential groove, are provided in a circumference surface of the clamping collar. 
     
     
         22 . A protective guard for a power tool, in particular for a hand-held power tool such as an angle grinder, which fastens to a clamping collar of the power tool by means of a fastening device which has a clamping band which is placed around the clamping collar and clamped to it by means of an actuating element, wherein a section of the clamping band is embodied in the form of a pivoting section that is pivotably secured to an adjoining section of the clamping band and with a loosening of the actuating element, it is possible to move the pivoting section of the clamping band into a radially pivoted-open position. 
     
     
         23 . The protective guard as recited in  claim 22 , wherein an inside of the pivoting section on the clamping band is provided with at least one locking element that rests against the clamping collar when the clamping band is clamped. 
     
     
         24 . The protective guard as recited in  claim 22 , wherein as the loosening occurs, the actuating element acts on the pivoting section, which is able to move into the radially pivoted-out position. 
     
     
         25 . The protective guard as recited in  claim 23 , wherein as the loosening occurs, the actuating element acts on the pivoting section, which is able to move into the radially pivoted-out position. 
     
     
         26 . The protective guard as recited in  claim 24 , wherein a hold-down device is situated on the clamping band and is acted on by the actuating element. 
     
     
         27 . The protective guard as recited in  claim 25 , wherein a hold-down device is situated on the clamping band and is acted on by the actuating element. 
     
     
         28 . The protective guard as recited in  claim 26 , wherein as the loosening occurs, the actuating element acts on the hold-down device with a component that causes the pivoting section to expand radially. 
     
     
         29 . The protective guard as recited in  claim 27 , wherein as the loosening occurs, the actuating element acts on the hold-down device with a component that causes the pivoting section to expand radially. 
     
     
         30 . The protective guard as recited in  claim 26 , wherein the hold-down device extends radially outward on the clamping band. 
     
     
         31 . The protective guard as recited in  claim 30 , wherein the hold-down device extends with a tangential component on the clamping band. 
     
     
         32 . The protective guard as recited in  claim 22 , wherein the actuating element is embodied as a screw that acts on the pivoting section. 
     
     
         33 . The protective guard as recited in  claim 32 , wherein the screw is guided through radially flaring end sections of the clamping band and the screw extends at least essentially tangential to the clamping band. 
     
     
         34 . The protective guard as recited in  claim 32 , wherein the screw extends radially to the clamping band and in the clamped position, connects overlapping end sections of the clamping band. 
     
     
         35 . The protective guard as recited in  claim 22 , wherein the pivoting section is connected in articulating fashion to the adjoining section of the clamping band by means of a pivoting hinge. 
     
     
         36 . The protective guard as recited in  claim 35 , wherein the pivoting hinge is embodied as a separate component that is secured to the clamping band. 
     
     
         37 . The protective guard as recited in  claim 35 , wherein the pivoting hinge is embodied as a section with a reduced wall thickness.
