Embodiment Construction

[0027] figure 1 A partial side view of a portable grinding tool 10 is shown. Its grinding disc 22 is visible in the region of its front edge 28 with a grinding blade 24 held thereon. The grinding disc 24 is wound along the underside of the grinding disc 22 and its front edge 28 and guided onto its upper side 26 . In this case, the grinding disc end 25 is placed on a pivot frame 34, wherein the end is first guided via the lever arm 36 close to the edge as far as its lever arm 38 facing away from the edge, and there it is guided in a transverse direction. A positively fitted clamping arm 49 in the groove 39 can be pressed into this transverse groove 39 with a non-illustrated friction-enhancing lining. Through the rotation of the rotary knob 43 and the axial downward movement of the rotary clamping rod 42 about its axis of rotation 44, the grinding disc end 25 is fixed against undesired loosening between the clamping arm 49 and the transverse groove 39 and through the The rota...

Abstract

Portable grinding tool (10), which has a grinding disc (22), on the underside of which a grinding disc (24) can be fastened, which is surrounded by its end (25) On the mutually opposite grinding disc edges (28, 30) and on them or on the two ends of the upper side of the grinding disc (22) are fixed by clamping devices close to the edge, forming the pivot frame (34) , can be simplified by the following measures: the grinding disc (24) is fixed by the holding device (38, 48, 49, 58) on the area away from the edge by its respective grinding disc end (25) and can be on the area close to the edge Movement upwards and thereby tensioned.

Description

technical field [0001] The invention relates to a portable grinding tool with a grinding disc, on the underside of which a grinding disc can be fastened, the grinding disc surrounding two mutually opposite grinding disc rims with its ends On and thereon or at both ends of the upper side of the grinding disc can be fixed by edge-proximate clamping devices consisting of pivoting frames. Background technique [0002] A portable grinding tool is known from DE 101 39 548 A1, which is provided with a system for clamping and tensioning a grinding disc held on the underside of its grinding disc. The system works very reliably and can be operated very well. It protrudes beyond the rear edge of the grinding disc and thus makes it more difficult to grind flush with the upper edge of the step and the like with the rear edge of the grinding disc. [0003] Edge-flush grinding with this system is only possible using the front edge of the grinding disc. [0004] According to US Pat. No. ...
