Device for smoothing

Abstract

A device ( 1 ) for smoothing filling or plaster compounds and/or for spreading them by rubbing, comprising a smoothing plate ( 2 ) with a smoothing side ( 3 ) and a fastening side ( 4 ), a handle ( 5 ) and a holding element ( 6 ) which connects the handle ( 5 ) and the smoothing plate ( 2 ) on the fastening side ( 4 ), wherein the holding element ( 6 ) has a fastening flange ( 7 ) for fastening the smoothing plate ( 2 ), and a handle-fastening section ( 8 ), is intended to be improved in such a way that the handle is connected to the smoothing plate in a particularly stable manner without the weight of the device and the manufacturing costs being substantially increased. This is achieved in that the fastening flange ( 7 ) has a multiplicity of holes ( 9 ) into each of which there protrude fastening bolts ( 10 ) which project on the smoothing plate ( 2 ), said fastening bolts being fixedly connected to the smoothing plate ( 2 ) on the one hand and being connected to the fastening flange ( 7 ) by means of a pressed connection on the other hand.
