  • the sandpaper is fixed by means of clamping jaws to the sanding plate which forms the lid of the suction chamber.
  • the sandpaper that grips the suction plate holds the suction plate against the sanding plate. In order to hold the sanding plate securely even when the sandpaper is removed from the suction plate, retaining clips are provided.
  • the handle forms a mounting base extending between two connection points.
  • the mounting base may also be formed as a bracket, so that the two strap ends are connected at the two attachment points with the top of the grinding plate.
  • this carries a particular gimbal-mounted fitting, for a stem.
  • One end of the mounting base may form a male end which is inserted in a male shaft on the upper surface of the abrasive plate. The end opposite this insertion end can be connected to a bolt on the sanding plate.
  • the latch is preferably a pivot bolt which blocks a latching tab in a latching position.

  • the bottom of the suction chamber has a plurality of substantially uniformly distributed over the bottom surface Intake. These suction holes are aligned with suction holes of the rubber plate, which is located below the suction plate.
  • the in the FIG. 1 explosive and in FIG. 9 separately shown grinding plate 2 forms the basic unit of the device of the embodiment.
  • the grinding plate 2 consists of a rectangular base plate with stiffened longitudinal edge made of plastic.
  • On the underside of the plastic plate is a soft rubber plate 43.
  • the soft rubber plate 43 extends over the entire underside of the grinding plate 2 and serves as a soft support for a sandpaper, which is tensioned under the rubber plate 43.
  • the sandpaper can be tied by means of two jaws 13.
  • the jaws 13 are held by two jaw carrier 17.
  • the jaw carrier 17 are uniform extensions of the abrasive plate 2 and protrude to the top.
  • bearing axles 18 are provided, about which the jaw 13 is pivotable.
  • a clamping spring formed by a leg spring 19 the jaws 13 are held in the clamping position.
  • junctions 25, 29 for tying a handle 10 'or an actuating handle 10.
  • a first attachment point is formed by a U-shaped insertion slot 25 into which the insertion end 26 of the handle 10 and the handle 10th 'is plugged.
  • the other fastening point is formed by a binding projection 29 which can be inserted into an insertion opening 30 of the handle 10 or of the handle 10 '. From the captive projection 29 protrudes a locking lug 36, which can dip into a latching recess 39 of a locking tab 37 of the handle 10 and the handle 10 '. Before the locking tab 37 is a pivot bolt 27.
  • the pivot bolt 27 is fixed with a rotation axis 38 on Befest Trentsböckchen the sanding plate 2. On its side facing the binding projection 29 broadside of the pivot bolt 27 has a retaining projection 32 which rests in the locking position in a retaining recess 31 of a Fesselungsfortsatzes 28 of the handle 10 and the handle 10 '. In its locking position of the pivot bolt 27 blocks a displacement of the locking tab 37 from the locking position with respect to the locking lug 36th
  • the pivot latch 27 has associated latching shoulders 41 which lie behind the latching projections 40 in the locking position.
  • the locking shoulders 41 are clipped there.
  • a release position is achieved. In this release position, the retaining projection 32 is no longer in planar contact with the outer wall of the retaining recess 31.
  • the locking tab 37 can now escape laterally, so that the latching lug 36 can escape from the latching recess 39.
  • the side of the handle 10 or of the handle 10 'forming the binding extension 28 can now be pulled off the binding projection 29. Subsequently, the insertion end 26 can be pulled out of the insertion shaft 25.
  • the handle 10 has approximately centrally between the bondage extension 28 and the insertion 26 ball bearing block 34, between which a cardan joint in the form of a bearing ball 33 is rotatably clamped. On the bearing ball 33, a connector 35 is attached to a stem.
  • the handle 10 can be exchanged for a handle 10 'having a bow-like shape.
  • a strap end of the handle 10 ' forms the insertion end 26 and the other strap end of the insertion opening 30, which is attachable to the bondage projection 29.
  • the suction plate 1 Under the soft rubber plate 43 of the grinding plate 2, a suction plate 1 can be clamped.
  • the suction plate 1 has the shape of a tub. It has a bottom 8, which has a multiplicity of essentially uniformly distributed intake openings 9.
  • the floor 8 is surrounded by side walls 4, 5, 6, 7.
  • a longitudinal side wall 4 forms a Staubabsaugö réelle 14, which is connected to a suction nozzle 15, which carries a connection sleeve 16 at its end.
  • a step 11 extends.
  • the step 11 is located on the suction chamber 3 facing side of the side walls 4, 5, 6, 7. In the assembled State rests on the step 11 of the edge of the rubber plate 43 of the grinding plate 2.
  • retaining clips 20 form hook ends 23 which can be hooked over the edge reinforcements of the sanding plate 2 to firmly bind the sanding plate 2 to the suction plate 1.
  • the retaining clips In order to bring the retaining clips 20 in this locking position or to release from the detent position, the retaining clips have 20 actuating tongues 24th
  • a rubber plate 42 for resting on a sandpaper strip, the ends of which are held by the jaws 13.
  • the device for sanding plasterboard walls is thus suitable for use both as a sanding device with and without a suction plate 1.
  • the sanding plate 2 may optionally be combined with various handles 10 ', 10.
  • This rasp tool 46, 47 is optionally combined with the handle 10 or the handle 10 '.
  • the rasp tool consists of a plastic rasp housing 46 which forms the insertion shaft 25 and the binding projection 29 and the pivot bolt 27 and a rasp plate 47 which is connected to the underside of the rasp housing 46.
  • a cap 44 is provided here, which is in combination with a handle 10 'in a rearward free space of the handle bracket.
  • Other grinding tools can be combined, for example, to grind internal angles or to grind rounds. In terms of structure, these additional grinders are in the Figures 11 and 12 shown rasp similar. However, the rasp plate 47 then has different sanding profiles.
  • FIGS. 13 to 15 a second embodiment is shown, which has a differently shaped pivot bolt 27 compared to the first embodiment.
  • the pivoting bolt 27 now has at its free end an obliquely projecting grip tongue 48.
  • the bondage extension 28 has a grip tongue 48 adapted slot-shaped recess 49, in which the grip tongue 48 rests in the locking position.
