Definitions

  • the present invention relates to a device for fixing a pad of fibrous material, as well as a surface cleaning machine equipped with said device.
  • the invention applies to the fixing, in a surface cleaning machine, of an alternative support or of a rotary cleaning disc made of fibrous material.
  • a large number of plastic pins have been used for this purpose, distributed over a support of shape corresponding to that of the cleaning disc at variable inclinations with respect to said support, as described in US Pat. 739.
  • This solution is not entirely satisfactory. Indeed, on the one hand, it is not easy to make the pins penetrate into the fibrous material because of their too great flexibility and, on the other hand, once they have penetrated into the fibrous material, they do not provide an absolutely effective fixing of the cleaning disc, and the latter, in operation, that is to say rotating at high speed, may escape from the support. Furthermore, the progressive clogging of the disc, after a more or less prolonged use, generally makes it even more difficult for the spikes to penetrate the fibrous material, during the inversion of said disc in order to use the clean side thereof.
  • the object of the present invention is to avoid these drawbacks, and relates to a device for fixing a pad of fibrous material, by means of which the latter, whether it belongs to a cleaning utensil or whether it constitutes a rotating disc. a surface cleaning machine can be easily and securely attached to a support even in the event of clogging of said pad.
  • the device for fixing a pad of fibrous material is remarkable, according to the invention, in that it comprises a plurality of sets of metal hooks, each set comprising a plurality of pairs of said hooks, said hooks being fixed to a support, the hooks of each pair being opposite one another.
  • said assemblies are rectilinear.
  • either the hooks of each pair are opposite one another, or the hooks of a set are staggered.
  • the hooks can be partially embedded in a layer of resin provided on said support.
  • each set of hooks is produced from a helical spring cut longitudinally.
  • each set of hooks is produced from a spring of triangular cross section cut longitudinally.
  • each pair of hooks has a general shape of V, the ends of the branches of which are curved inwards.
  • each set of hooks is constituted by a plurality of pairs of hooks connected by a rod secured to the bottom of the V.
  • the device for fixing a surface cleaning disc made of fibrous material, the device comprises a support of discoid shape corresponding to that of said cleaning disc, on which support are provided sets of hooks for attaching said disc. cleaning said support.
  • said sets of hooks are radial.
  • Figures 1 and 2 illustrate a first embodiment of the hooks of the fixing device according to the invention.
  • Figures 3 and 4 illustrate a second embodiment of the hooks of the fixing device according to the invention.
  • Figures 5 and 6 illustrate a third embodiment of the hooks of the fixing device according to the invention.
  • FIG. 7 illustrates an example of arrangement of rectilinear sets of pairs of hooks according to the invention.
  • Figure 8 is a schematic perspective view of a machine for surface cleaning which can be equipped with the fixing device according to the invention.
  • Figure 9 is a partial top view of a support disc having radial sets of pairs of hooks according to the invention.
  • Figure 10 is a cross-sectional view of the disc of Figure 9.
  • FIG. 1 The figures of the appended drawing illustrate different embodiments of the device for fixing a pad of fibrous material according to the invention ( Figures 1 to 7), as well as the use of such a device in a surface cleaning machine ( Figures 8 to 10).
  • the fixing device of the invention comprises sets 1, in particular rectilinear, of pairs 2 of metal hooks 3 fixed on a support 4, the hooks 3 of each pair 2 being opposite one another.
  • the hooks 3 can be fixed to the support 4 by means of a resin layer 5 provided on the latter.
  • FIG. 7 illustrates a possible arrangement of a number of straight sets 1 of pairs of hooks 3.
  • the hooks 3 of a set 1 can be staggered (FIGS. 2 and 4). Each set 1 of hooks 3 can then be obtained from a helical spring cut longitudinally ( Figures 1 and 2), or from a spring of triangular cross section cut longitudinally ( Figures 3 and 4).
  • the cut part L1 of the spring can correspond, for example, to 2/8 of the "diameter" of the latter, the part L3 embedded in the resin layer 5 and the part L2 projecting therefrom, each corresponding to 3/8 of said diameter.
  • the vertices of two opposite hooks can form projections of different heights; moreover, the cut part L1 of the spring can be cut along an inclined plane relative to the free surface of the layer 5.
  • half of the "height" of the spring can be embedded in the resin layer 5, the other half protruding from this last.
  • each pair 2 of hooks 3 facing one another has a general shape of V whose ends 7 of the branches are curved inward.
  • each set 1 of hooks 3 is constituted by a plurality of pairs 2 of hooks 3 connected by a rod 8 secured to the bottom 9 of the V.
  • the machine 10 for surface cleaning shown in FIG. 8, comprises a chassis 11 on which is mounted a motor 12. Two wheels 13 are arranged on either side of the chassis 11 at one end of the latter. Furthermore, a handle 14, equipped with a handle 15 and operating members 16, is connected to the chassis 11, on the side thereof where the wheels 13 are arranged.
  • the motor 12 is intended to drive a rotary tool 17, possibly wrapped by a protective cover (not shown).
  • the tool 17 comprises a disc-shaped support 18 to which is fixed a disc 19 for cleaning the surface of fibrous material, of corresponding shape.
  • the cleaning disc 19 is fixed to the support 18 by sets 1 of hooks 3, advantageously radial, partially embedded in the support 18 (FIGS. 9 and 10).
  • the hooks 3 have been shown in accordance with the first embodiment shown in Figures 1 and 2. However, it is understood that other forms of hooks, such as those shown in the Figures 3,4 and 5,6, could be used in this application.
