Dust collector for angle grinder

Abstract

A dust collector for an angle grinder comprises a collector body for covering a circular grinding disk, a sealing element for sealing at least some sections of the collector body from a surface to be machined by the grinding disk, at least some sections of the sealing element being placeable in a first and a second retaining rail, and a suction terminal via which the abraded surface particles can be sucked off the collector body. The first retaining rail extends along a closed periphery of the collector body, and in the collector body, the sealing element is spring-mounted by at least one spring element in the axial direction relative to the axis of rotation of the grinding disk.

 wherein the at least one spring element is formed as a single piece.   
     
     
         10 . The dust collector for angle grinders according to  claim 1 ,
 wherein the at least one spring element has a spring stiffness in the axial direction which is less than a stiffness of the sealing element.   
     
     
         11 . The dust collector for angle grinders according to  claim 1 ,
 wherein a plurality of spring elements is provided along the closed circumference (U) of the collector body.   
     
     
         12 . The dust collector for angle grinders according to  claim 1 ,
 wherein the collector body has a central opening, wherein a drive spindle to which the circular grinding disk will be attached can project through the central opening wherein a groove is formed on the central opening such that the collector body can be attached to an angle grinder with a positive fit, and therefore fixed to the frame thereof.   
     
     
         13 .
