Definitions

  • the invention relates to a grinding device for windshield wiper blades with two V-shaped abrasive jaws which are provided with a coating having an abrasive grit and which accommodate the windshield wiper blade between them, the grinding jaws being arranged on a pair of tongs whose bow arms, at the free ends of which the grinding jaws are located, can be moved resiliently to one another.
  • the disadvantage of these devices is that they are rigid and are only suitable for processing a single type of wiper blade.
  • the object of the invention is to provide a grinding device which can be adapted to several types of wiper blades. Furthermore, an even, sensitive pressure should be able to be exerted on the wiper blade during the grinding process in order to improve the grinding result.
  • the objects of the invention are achieved in that the grinding jaws are angled in the direction of insertion of the wiper blade and thus a front one
  • the grinding section with a larger and a rear grinding section with a smaller angle and that a limiting web adjoins one of the grinding jaws and is aligned transversely to the direction of insertion of the wiper blade and is provided with a coating having an abrasive grain.
  • the special feature of the device is that by pressing the pliers together not only the front rubber edge, but also the two side parts of the front web can be gripped evenly. This is not the case with the known rigid devices.
  • a preferred embodiment of the invention provides that the grinding jaws wipe in the direction of insertion of the windshield wiper blade. are and delimit a front section with a larger and a rear section with a smaller angle.
  • the grinding jaws delimit an angle of between 50 and 80 °, preferably 65 ° in the front area and an angle of between 5 and 15 °, preferably 10 °, in the rear area.

Abstract

Un dispositif d'affilage pour lames (5) d'essuie-glace comprend deux mâchoires d'affilage (10), formant un V, pourvues d'un revêtement à grain abrasif (3) et qui reçoivent entre elles la lame (5) d'essuie-glace. Les mâchoires d'affilage (10) sont montées sur un arc (1) similaire à une pince, aux extrémités libres de bras (2) qui sont élastiquement mobiles l'un vers l'autre. Les mâchoires d'affilage (10) sont courbées dans la direction d'insertion de la lame (5) d'essuie-glace et délimitent ainsi une section antérieure (7) ayant un angle plus large et une section postérieure (8) ayant un angle plus étroit.
