  • the generic devices are used in particular to coatings on walls, ceilings and floors, z. As plasters to smooth. For this, it is important to guide the device over the surface to be machined so that the rotatable tool, in particular a grinding wheel, acts with uniform pressure distribution on the surface to be machined and runs as quietly as possible. In this regard, the known devices are in need of improvement.
  • the present invention has for its object to improve a device of the type mentioned above and in particular on difficult to reach surfaces, for. B. where a wall and a ceiling collide, the movement of such a device and to achieve a uniform pressure distribution of the force acting on the surface tool.
  • the stem ends at a distance from the head.
  • the head is supported by a support hose attached to the handle which, when working by a user, transfers pushing and pulling forces to the head, for example to work on a building ceiling and, with the handle, applies pressure to the wearer's head via the support hose Exercise surface processing device, so that a fixed on the tool plate grinding or polishing agent can act on the building ceiling.
  • the head is movably attached to the stem, so that the orientation of the head relative to the stem at work can be easily adapted to given requirements. In particular, it can be achieved that the head can tilt relative to the stem in any direction.
  • a device according to the invention therefore, in particular, building ceilings and corners between walls or ceilings can be processed more easily.
  • the device according to the invention is therefore very versatile, z. Gypsum for smoothing plasters, paints for removing old paint jobs, and smoothing the substrate for a new paint job; of wallpapers for removing old wallpaper and for smoothing the surface of new wallpaper; floor levelers for sanding off adhesive residue and smoothing the floor before laying a new floor covering; parquet flooring for sanding a laid parquet floor; of locksmiths for smoothing or derusting metal structures in a building or building or for removing coatings on metal surfaces, and more. Because of the ease of handling, the device according to the invention is not only suitable for craftsmen, but also for home improvement.
  • the carrier hose may for example be a metal hose, in particular a winding hose. It is also possible that the support tube is composed of rings or pipe sections which are mutually movable, so this results in a sufficient flexibility. Suitable rings or pipe sections may be made of metal or plastic, for example.
  • the carrier hose is preferably designed such that it generates a restoring force when the head is tilted relative to the handle. In this way, the head always returns by itself to its original position.
  • the carrier tube may be a plastic tube which may be stiffened by a helical spring.
  • the carrier tube may also be a corrugated tube. Additional measures for stiffening can advantageously be dispensed with in the case of a corrugated hose, so that a suitable bending strength can be realized in a particularly advantageous manner, which prevents unintentional tilting of the head when machining a building ceiling and, on the other hand, provides the necessary flexibility for a desired tipping, for example for editing a wall or floor surface, guaranteed.
  • For the length of the carrier tube between its attachment to the head and its attachment to the stem a length between 4 cm and 15 cm, preferably 5 cm to 10 cm, is preferred in order to allow advantageous bending stiffness and ergonomic working.
  • the shaft is passed through the carrier tube.
  • the shaft is protected by the carrier hose.
  • a suction hose preferably leads from the head to the handle for the suction of dust produced during the abrasive machining of surfaces, so that the amount of dust released can be considerably reduced by means of a suction unit connected to the suction hose.
  • the shaft is passed through the suction hose.
  • the stem is preferably hollow. It can thus accommodate the flexible shaft, which connects the tool plate with the drive unit. In this way, the craftsman can carry the drive unit on the body or park on the ground.
  • the weight of the drive unit when handling the device must not be caught on the stem.
  • the shaft between the drive unit and the handle is surrounded by a protective tube.
  • the protective tube carries at a distance from each other arranged ring segments to protect against over-bending of the shaft. Due to the thickness of the ring segments and their spacing, the maximum possible bending radius of the protective tube can be specified.
  • the stem has a handle. This measure has the advantage that the device can be handled more easily while working.
  • a further advantageous development of the invention provides that the handle has two sections connected by a hinge. In this way, an adjustment of the angle of the head with respect to the stem is possible, so that an adaptation can be done while working.
  • the joint is lockable. In this way, an advantageous angle in the given work can be more easily maintained. It is preferred that on the side facing away from the head portion of the Stiels a device for releasing a locking of the joint is mounted. This has the advantage that a lock, which is no longer advantageous after completing a work step, can be solved by simple means. It is further preferred that the joint is uniaxial. It can also multi-axis joints are used, but these are more expensive.
  • FIG. 1 shown surface processing device has a handle 1, on which a head 2 is movably mounted.
  • a head 2 is rotatably in FIG. 2 shown tool plate 3 stored.
  • tool plate 3 On the tool plate 3, for example, a grinding or polishing agent can be attached.
  • a drive unit 4 To drive the tool plate 3 is a drive unit 4, which is coupled via a flexible shaft 5 to the tool plate 3.
  • the shaft 5 terminates in a stepped sleeve 9, whose end is formed as a polygonal, for example as a square, and is seated in a polygonal sliding fit in a sleeve 13.
  • a sliding fit is therefore chosen to make a length compensation possible.
  • a ball bearing 14 is arranged for friction reduction.
  • the stem 1 includes two via a lockable joint 6 interconnected stem sections 1a, 1b.
  • the lockable joint allows adjustment of the angle of the head 2 with respect to the style 1, so that adjustment can be made while working.
  • the head 2 facing stem portion 1 a is formed as a fork, hiss the head 2 facing tines the shaft 5 can oscillate in a tilting of the head 2 relative to the stem 1.
  • the stem portion 1b carries a Handle 14 and a device, not shown, for releasing a locking of the joint 6, for example, an actuating lever which can open a latching mechanism via a pull cable.
  • the head 2 is a fixed to the stem 1 carrying hose 7, which in FIG. 2 shown is worn.
  • the carrier tube 7 is in the illustrated embodiment, a metal tube and has a sufficient rigidity to transfer when working by a user on the stem 1 exerted pushing and pulling forces on the head 2.
  • the head 2 can be pressed via the support tube 7 by a force exerted on the stem 1 force against a building ceiling, so that it can be processed by erosion.
  • the hose is flexible against a restoring force, so that the position of the head 2 relative to the handle 1 can be easily adapted to the conditions of a surface to be machined.
  • An advantageous flexural rigidity of the carrier tube 7 can be achieved, for example, in that it is designed as a corrugated tube.
  • the head 2 can be tilted in this way by 180 ° relative to the stem 1, namely until the head 2 on the stem segment 1a, which is designed as a fork strikes.
  • the carrier tube 7 is attached to the stem 1 and the head 2 by means of a clamp 8a, 8b.
  • it may for example also be cohesively, in particular by gluing, fixed.
  • the carrier tube 7 has a length of 4 cm to 15 cm, in particular 5 cm to 10 cm.
  • the flexible shaft 5 is passed through the carrier tube 7 in the illustrated embodiment.
  • the carrier tube 7 is surrounded by a suction hose 10, which is used to aspirate when eroding surfaces resulting dust serves and leads from a hood 16 of the head 2 to the stem 1.
  • the stem 1 is formed on a part of its length as a tube to which the suction hose 10 is connected. At its end facing away from the head 2 end of the stem 1 is provided with a connecting piece 11 for a vacuum cleaner.
  • the intake hose 10 and thus also the shaft 5 surrounded by it can oscillate in the fork 1a, resulting in a compact and flexible construction of the device.
  • In its adjoining the head 2 area of the suction hose 10 is formed as a bellows 10 a, to follow tilting movements of the head 2 well.
  • the Staubabsaughaube 16 is endlessly rotatable about its central axis and opened on one side.
  • the lateral opening makes it possible to bring the tool plate closer to a wall when processing a ceiling or floor surface.
  • the rotatability of the hood 16 makes it possible to turn the opening to where it is needed.
  • the drive unit 4 of the illustrated embodiment can be worn while working on the body, for example, by being attached to a belt, or placed on the floor. In this way, the weight of the drive unit 4 does not burden when working, which is an important advantage especially when editing building ceilings.
  • the drive unit 4 is movably connected to the stem 1 via the flexible shaft 5. Between the drive unit 4 and the stem 1, the shaft is surrounded by a protective tube 12.
  • the protective tube 12 carries at a distance from each other arranged ring segments.
  • the ring segments give by their thickness and the distance from each other before the maximum possible bending angle of the protective tube 12 and thus protect the shaft 5 against overbending.
  • the ring segments of the protective tube 12 can be splashed around the protective tube 12, for example.
  • FIG. 3 shows a modification of the in FIG. 2 illustrated embodiment, wherein in FIG. 3 for clarity, the bellows 10a is not shown. Essentially, this differs in FIG. 3 illustrated embodiment of the in FIG. 2 illustrated embodiment only in that the flexible shaft 5, which has a shaft core 5a and the shaft core 5a surrounding wave sheath 5b, bearing 17 which surrounds the wave core 5a. Camps 17 cause the wave core 5a can advantageously rotate friction in the wave cover 5b.
  • the bearings 17 are designed as rolling bearings, namely as a needle bearing. In principle, however, plain bearings can be used
  • the shaft 5 preferably contains a larger number of such bearings, for example 5 to 20 bearings, which are arranged in the shaft 5 at a distance of several centimeters, for example 5 cm to 10 cm. In this way, in the regions of the shaft 5 subjected to bending, friction between the shaft cover 5b and the shaft core 5a can be drastically reduced.
  • Such bearings 17 are particularly advantageous in the area surrounding the protective tube 12 region of the shaft 5.
