  • These rolling bearings 27a-27g define the axis X4 and receive in rotation the transmission bar 26, as illustrated for example by figure 4 .
  • the second part 23 also comprises a first housing 33 in a square and a second semi-cylindrical housing 34 which receive a second square end 26b of the transmission bar 26, illustrated in figure 15 , which makes it possible to subject said second part 23 to the transmission bar 26 and, consequently, to the first part 22 integrating the lever 20.
  • This assembly appears for example in figure 19 .
  • the first part 22 comprises a transmission tab 35 which is provided with a light 36, as illustrated in figure 11 .
  • the second part 23 comprises a transmission tab 37 provided with a light 38, as illustrated in Figures 9 and 10 .
  • These two transmission lugs 35 and 37 are arranged respectively opposite the two angled ends 26a-26b of the transmission bar 26, on the lateral sides of the sole 5, as illustrated for example in figure 19 .
  • the support piece 12 comprises on its lateral sides 12a-12b two housings 39a-39b each receiving pivotally, along a transverse axis X5, a first part 40a of a connecting rod 40 held in pivot connection by means of a connecting axis 41 .
  • the connecting rods 40 is shown on the lateral side 12b of the support piece 12 so as to leave visible the housing 39a and the connecting pin 41 on the other side 12a; it goes without saying that the connecting rod 40 will be positioned in this housing 39a before the establishment of the connecting pin 41.
  • each connecting rod 40 comprises on its second part 40b a slot 42 in which is housed the transmission lug 35 of the first part 22 on the lateral side 12b of the support part 12 and, similarly, in which is housed the transmission lug 37 of the second part 23 on the lateral side 12a of said support part 12.
  • a pin 43 illustrated in figure 14 , is housed in the hole 44 on the second part 40b of the connecting rod 40 and in the light 36 of the transmission lug 35 on the first part 22, likewise in the light 38 of the transmission lug 37 on the second part 23 .
  • the support piece 12 comprises two hollow cylindrical portions 45a-45b respectively having the guide holes 18a-18b, inside which are housed springs (not shown) which receive the guide rods 19a-19b and which take bearing on cross-pieces 46a-46b arranged on the upper side of the sole 5, which forces the support piece 12 upwardly with respect to the sole 5 when nothing retains said support piece 12.
  • the transmission lugs 35 and 37 make it possible, by means of the connecting rods 40, to translate the support piece 12 downwardly relative to the sole 5, which allows the brushes 13-14 to be removed and to have them projecting vis-à-vis the lower face 15.
  • the brushes 13-14 can rest on the surface S to be sucked and the lower face 15 of the sole 5 remains detached from said surface S.
  • the first part 22 comprises a stop finger 47 which is positioned under the lever 20, as illustrated in figure 11 .
  • the second part 23 comprises an abutment finger 48.
  • the branches 6-7 of the fork 3 each include an end portion 6c-7c which extends beyond the axis X2 of pivoting of said fork 3 relative to the sole 5, as illustrated in figure 12 .
  • These end portions 6c-7c each include a support finger 49-50.
  • the stop fingers 47-48 are arranged respectively in the fields of rotation of the support fingers 49-50.
  • the stop fingers 47-48 are positioned at the highest point which allows the fork 3 to tilt backwards in the direction of the arrow 11 a illustrated in figure 2 , by pivoting relative to the sole 5, until the bearing fingers 49-50 come into contact with the stop fingers 47-48 as illustrated in figure 5 .
  • the fork 3 can tilt forward in the direction of the arrow 11b illustrated in figure 2 , until the bearing fingers 49-50 come into contact on two abutment pieces 51-52 arranged on the upper face 53 of the sole 5.
  • the wheels 4a-4b tend to rise from the surface S to be sucked, the mass of the fork 3, of the wheels 4a-4b and of the sleeve 2 then having the effect of ballasting the sole 5 and of tilting it backwards in the direction of the arrow 54 illustrated in figure 3 , until the wheels 4a-4b are in contact with said surface S.
  • the underside 15 of the sole 5 comprises a rear part 15b which is inclined upwards relative to its front part 15a; the ballasting performed thus makes it possible to tilt the front part 15a of the sole at an angle ⁇ 1 relative to the surface S, as illustrated in figure 2 .
  • this angle ⁇ 2 corresponds to the angle of inclination of the surface S to be cleaned with respect to the front part 15a on the lower face 15, which makes it possible to bring said rear part 15b in the immediate vicinity of the surface S to be cleaned, as the figure 3 .
  • this angle ⁇ 2 is between six degrees and eleven degrees (6 ° ⁇ 2 ⁇ 11 °).
  • the angle of inclination is determined according to the air flow generated by the motor-driven fan of the vacuum cleaner.
  • the greater the air flow the greater the angle of inclination ⁇ 2.
  • the angle of inclination is around 7 °, for a flow rate of 28I / s the angle is around 10 °.
  • the edge 15c between the front part 15a and the rear part 15b on the underside 15 of the sole 5 makes it possible to scrape the surface S to be vacuumed.
  • This edge 15c corresponds substantially with the rear edge 55a of the cavity 55.
  • This cavity 55 communicates with a nozzle 56, as shown in the figure 20 , which is connected to the sleeve 2 by means of a flexible conduit 57 shown diagrammatically in dotted line on the figure 1 .
  • the position of the edge 15c between the front part 15a and the rear part 15b on the underside 15 of the soleplate makes it possible to limit or even eliminate air leaks at the rear of the suction head and therefore to reinforce the suction force at the front of the nozzle, in particular on the surfaces S to be cleaned of textile type.
  • the first part 22 comprises a stop lug 58 provided with a lug 59 and the second part 23 also includes a stop lug 60 provided with a lug 61.
  • These lugs 59 and 61 are arranged facing each other when the parts 22 and 23 are mounted on the transmission bar 26.
  • the stop lugs 58 and 60 are flexible or flexible on the parts 22 and 23.
  • the extension tab 29 on the upper face 53 of the sole 5 comprises on its outer side 29a a groove 62 of circular shape.
  • the extension tab 31 comprises on its external side 31a a circular groove, not visible in the figures, but identical to the groove 62.
  • These grooves 62 each comprise an orifice 63-64 positioned more or less in the central part of said grooves 62, as illustrated in figure 8 .
  • the pins 59 and 61 are respectively housed in the grooves 62 when the parts 22-23 are mounted on the sole 5, said pins 59 and 61 coming to lightly bear in the bottom of these grooves 62. Due to the flexibility of the legs 58 and 60, the pins 59 and 61 penetrate inside the orifices 63-64 when they correspond, which stops the position of the parts 22-23 and, consequently, that of the lever 20. The lever 20 and the mechanism are in second position in this configuration.
  • the flexibility of the stop tabs 58 and 60 allows the lugs 59 and 61 to be released outside the orifices 63-64, thus allowing actuation of the mechanism 21 and of the lever 20.
  • the pins 59 and 61 then move in the respective grooves 62 until they come, in one direction, into abutment against the first ends 62a of said grooves 62 where the lever 20 and the mechanism 21 have reaches the first position or, in the other direction, in abutment against the second ends 62b of said grooves 62 where the lever 20 and the mechanism 21 have reached the third position.
  • parts 22-23 each include a stop plate 65-66.
  • the extension tabs 28 and 32 on the sole 5 include on their external sides 28a and 32a protrusions 67-68.
  • the stop plates 65-66 respectively come to bear on these protuberances 68-67, as illustrated by the Figures 4 and 5 .
  • These abutment plates 65-66 and protrusions 68-67 ensure an adequate distribution of the forces over the width of the sole 5, in association with the grooves 62 and lugs 59 and 61, when the lever 20 returns to the first position.
  • the second part 23 comprises a tab 69 provided with a protuberance 70 on its external side 69a, said protuberance 70 coming to bear against the internal side 28b of the extension tab 28 on the sole 5, as illustrated in FIG. figure 7 .
  • the suction head 1 also includes a stop piece 71 illustrated in figure 17 , which is fixed to the sole 5 and which includes a groove 72 in which the rear brush 14 is housed, as illustrated in figure 19 .
  • a stop piece 71 illustrated in figure 17 which is fixed to the sole 5 and which includes a groove 72 in which the rear brush 14 is housed, as illustrated in figure 19 .
