Definitions

  • the object of the present invention is to enable the production of a machine capable of ensuring the fine smoothing of the coatings previously applied to a surface, for example using a conventional float.
  • it comprises at least one working head equipped with tools which rotate by the fact that this head is fixed on a plate which is rotated by a drive mechanism, said head being however fixed on the articulated axis which supports it. , all in order to automatically smooth the plaster, without using a blade or trowel of the usual type.
  • the drive mechanism is itself rotated by means of a rotating and flexible metal wire which is enclosed by a sheath coming from an actuating assembly, which is mounted on a carriage fitted with wheels.
  • the plate is supported by the operator, either directly by hand when he is working on a vertical wall, or suspended from the shoulder with a strap when he has to work on a ladder or on a scaffolding for fine reading of a ceiling. In the latter case, it is preferable to provide an elastically deformable support capable of facilitating work on the ceiling.
  • Another remarkable feature resides in the easy interchangeability of the working heads which are capable of being replaced by other heads having different characteristics and uses.
  • the polishing machine comprises a carriage 1 on which is mounted an actuating assembly 2, comprising an electric motor for driving in rotation a turntable 6.
  • the carriage 1 also supports a pump for water or other coolant contained in a tank 3 for spraying said liquid at the working heads 7 and the wall on which said heads must work.
  • Fig. 2 shows in more detail the turntable 6 which is produced in the form of a circular plate equipped, in a first embodiment, with working heads 7 four in number. This plate is rotated by a worm-helical wheel 8 assembly driven by the actuating hose 4 of FIG. 1 from the electric motor mounted on the carriage 1.
  • Line 5 brings water or other suitable liquid to a spray nozzle 9 provided outside of the turntable 6 so to supply liquid to the working surface on which the heads act 7.
  • the number of heads mounted on the same turntable can be absolutely arbitrary, for example being between 1 and 5.
  • Fig. 3 illustrates in section the arrangement of one of the working heads 7 fixed elastically to the plate 6 by means of an axis 10 which has in its lower part 10 ′ a section with a square profile; this part 10 ′ passes through an opening, also of square section, formed in the hub 11 of reduced diameter of a disc 12 which encloses the open end 13 of the axis 10.
  • a spring 14 compressed between the hub 11 of the disc 12 and a guide cap 15 is held integral with the plate 6 by means of screws 16, for example with a flat head, thereby allowing limited movements of the working head in the vertical direction, which head can moreover be subjected to limited oscillations with respect to the work surface owing to the fact that the opening with a square section made in the hub 11 of the disc 12 has dimensions slightly greater than those of the square section of part 10 'of axis 10.
  • Fig. 4 and 5 show clearly the arrangement of the four working heads 7 on the turntable 6. More particularly, at that of these heads which is shown with the tool 17 detached, we can clearly see the "VELCRO" system 18 provided on disc 12.
  • the opening 19 allows the mounting of a single working head 7 as shown in fig. 6, against which a “VELCRO” system 18 (see fig. 8) can be fixed a first rigid support 20, then a tool 17 so as to obtain an embodiment similar to the previous one.
  • the detail of the mounting of the working head is particularly visible in fig. 9.
  • the disc 12 is provided on its lower part with a first "VELCRO" layer 18 suitable for fixing the support 20.
  • the latter is provided with a layer of "VELCRO" 21 at its lower part, so that the tool 17 can be fixed there.
  • FIG. 11 to 15 illustrate this characteristic well.
  • the support 22 housing the mechanism 8 on which is fixed the turntable 6 with the working heads 7. The operation of the assembly remains the same.
  • the support 22 comprises a first rectilinear part 23 (fig. 11) in which is housed the tail 24 of a quick connector for fixing the hose, a second part 25 which houses the mechanism 8, and a third part 26 oriented obliquely (fig. 13) and provided with an end buttonhole 27 capable of cooperating with the pivot 28 of a fork 29 integral with said mechanism 8, as illustrated in fig. 12.
  • the conformation of the support 22 thus guarantees effective retention of the mechanism 8 and of the plate with one or more heads, said plate being unable to disengage from the above-mentioned assembly.
  • This support 22 is completed by an extension 30 (see fig. 13, 14 and 15) which in its upper part is connected to said support by a hinge 31.
  • the function of this hinge 31 is to make the support 22 elastic so that the work head plate can be adapted to all types of ceilings.
  • Fig. 15 shows that on the extension 30, provided hollow, engages a rubber insert 32; after inserting this insert 32 and a sleeve 33 engaged externally on said extension 30, the assembly is locked using a screw 34 in order to prevent any movement of the two rubber elements 32 and 33.
  • the upper part of the insert 32 which projects a few centimeters, facilitates engagement inside another hollow part 35 welded to the support 22.
