Definitions

  • the invention relates to a broom for a self-propelled vehicle.
  • the invention relates more particularly, but not exclusively, to brushes that could be said to be "static”, that is to say whose bristles are not animated by any clean movement, other than that resulting from their contact with the surface. to sweep during the movement of the vehicle.
  • WO 2010/052384 describes a device for collecting objects where lateral deflectors make it possible to bring detritus back to a collecting platform. These deflectors are located at the front of the broom, in front of the tray.
  • a broom for a self-propelled vehicle comprising an elongated body which is equipped with means for adaptation to the vehicle and which comprises, at a lower face, a series of longitudinal rows of brush bristles extending in a substantially normal direction to the underside.
  • the rows of this series are parallel to each other and each having, seen from the lower face of the body, a curved shape or Cé or Vé.
  • Such a series of rows thus curved or in the form of Cé or Vé makes it possible to obtain a sweeping quality which is much better than that obtained with a broom comprising only rectilinear rows of bristles.
  • said series forms a collection area for concentrating a larger amount of sweeps.
  • the appearance of deposition lines or accumulations of detritus or dust along the path of movement of the blade is reduced, or appear after a distance of displacement much higher than in the case of a use of a broom comprising only rectilinear rows of bristles.
  • an object of the invention is to improve the sweeping quality of an adaptable broom on a self-propelled vehicle and more particularly, but not exclusively, the sweeping of a broom of the type described in the document.
  • the invention also aims to increase the recovery capacity of the sweeps.
  • the invention further aims to improve the recovery of sweeps at walls or other vertical obstacles.
  • a broom B object of the invention is intended to be adapted to a motor vehicle, for example a forklift.
  • the blade B comprises an elongate body 1 which is equipped with means 2 for adaptation to the vehicle.
  • the means 2 may be made in any appropriate manner depending on the nature of the vehicle.
  • the means 2 are designed to allow the assembly of the blade B on the forks of a forklift and comprise two sleeves arranged at the upper face of the body 1. Locking means, the pin type, allow to block the movement of the broom B relative to the forks of the truck.
  • the blade B comprises, at the lower face of the body 1, rows 10 whose brush bristles extend in a direction substantially normal to the underside of the body 1 ( figure 1 ).
  • the rows of bristles are preferentially divided into at least two series of rows S1 and S2. Preferably, a third row S3 of different conformation is provided. On the Figures 9 and 10 , the rows of bristles 110 are however distributed over a single series S0.
  • a first series S1 is formed of longitudinal rows 101 of brush bristles extending in a direction substantially normal to the lower face of the body 1.
  • the rows 101 of this first series S1 are advantageously parallel to each other and extend substantially over the entire length of the body 1 so as to reach, or at least be very close to, its lateral edges 11.
  • the first series S1 comprises two rows 101, but a greater or smaller number of rows may be provided .
  • the rows 101 are spaced from each other (appended figures) or on the contrary contiguous.
  • the rows 101 of the first series S1 advantageously each have, seen from the lower face of the body 1, a curved shape (for example an arcuate shape, without breaking, an elliptic curve portion shape, etc.) or in Cé or in Vé.
  • the rows 101 all have a Vee or chevron shape and are parallel to each other.
  • the two branches of the Ve are preferably rectilinear, but a configuration where the branches are not straight (for example curved or zigzag) can be considered.
  • the rows 101 are all arranged so as to be generally symmetrical with respect to a median transverse plane, said sagittal plane S, which passes through the tip of each of said rows.
  • An asymmetrical configuration of the rows 101 with respect to the plane S can be envisaged.
  • the constituent rows 101 of the first series S1 are arranged so that their concavity is oriented towards the front of the body 1, or that their tip is directed towards the rear of said body.
  • the front and rear of the body 1 are defined with respect to the direction and normal direction of travel D of the vehicle moving the blade B.
  • this configuration of the rows 101 - whose concavity is oriented towards the front - forms a first recovery zone Z1 where the sweeps 30 are collected and preserved when the operator controls the advance of the vehicle and that the broom B pushes in front of him said sweepings (detritus, dust, ...) present on the surface 3 to be cleaned.
  • the inclination of the rows 101 and the depth of the series S1 in particular define the storage capacity of the sweeps 3.
  • the first series S1 avoids a rapid appearance of sweep accumulation lines 30 at the side edges 11 of the broom B .
  • the rows 101 of the first series S1 present, seen from the lower face of the body 1, a rectilinear shape.
  • the rows 101 may be parallel - or not - to the longitudinal axis L of the body 1.
  • the body 1 further comprises, at its lower face, at least a second series S2 of longitudinal rows 102 of bristles. These extend in a direction substantially normal to the lower face of the body 1.
  • the second series S2 is disposed behind the first series S1 and shifted therefrom so as to define a collection zone Z2 of the sweeps 30.
  • the rows 102 are spaced from each other (appended figures) or on the contrary contiguous.
  • the rows 102 of the second series S2 are advantageously parallel to each other and, as for the first series S1, extend substantially over the entire length of the body 1 so as to reach, or at least be very close, side edges 11
  • the second series S2 comprises two rows 102, but a higher or lower number of rows may be provided.
  • the rows 102 of the second series S2 each have, seen from the lower face of the body 1, a curved shape (for example an arcuate shape, without breaking, an elliptical curve portion shape, etc.) or in Cé or in Vé.
  • the rows 102 of the second series S2 have the same shape and are parallel to the rows 101 of the first series S1.
  • the rows 102 all have a Vee or chevron shape and are parallel to each other.
  • the two branches of the Ve are preferably rectilinear, but a configuration where the branches are not straight (for example curved or zigzag) can be considered.
  • the rows 102 are all arranged so as to be generally symmetrical with respect to the plane S. An asymmetrical configuration of the rows 102 with respect to the plane S can however be envisaged.
  • the constituent rows 102 of the second series S2 are arranged so that their concavity is oriented towards the front of the body 1, or that their tip is directed towards the rear of said body.
  • This configuration makes it possible to form a second recovery zone Z2 where the scanners 30 can be collected and stored.
  • the inclination of the rows 102 and the depth of the series S2 define in particular the storage capacity of the sweeps 30 in the collection zone Z2.
  • the brush B offers two collection areas Z1 and Z2.
  • the storage capacity of the sweeps 30 is thus doubled compared with that of the sweeper described in FIG. patent document EP 2,269,484 cited above.
  • the recovery zone Z2 has a significantly increased storage capacity.
  • the rows 102 of the second series S2 are rectilinear and parallel to the longitudinal axis L of the body 1.
  • the second series S2 is disposed behind the first series S1 and shifted therefrom so as to define a recovery zone Z2.
  • the rows 101 of the first S1 may be rectilinear ( figure 8 ) or a curved shape or in Ce or Ve (as on the figures 1 , 2 , 4, 5, 6 and 7 ).
  • the second series S2 - whether it has a rectilinear or curved shape - is associated with deflectors 120 facing the front of the body 1 so as to reduce the sweeps 30 from the first series S1 - or which escape the passage zone of said first series - to the second collection zone Z2.
  • the deflectors 120 are located at each of the lateral ends of the row 102 of the second series S2 that is closest to the rows 101 of the first series S1. In this way, the sweeps 30 are directly driven into the collection zone Z2, and not inside the rows 102.
  • the new collection zone Z2 has a volume which can be substantial insofar as, as it appears in the appended figures, it is delimited longitudinally by the first row 102 (which is closest to the front edge of the body 1) of the second series S2 and the last row 101 (which is closest to the rear edge of the body 1) of the first series S1.
  • the collection zone Z2 is also delimited laterally by the deflectors 120.
  • the volume of the collection zone Z2 can be adjusted by adjusting the distance separating the two series S1 and S2 and / or by adjusting the deflector dimensions 120.
  • the baffles 120 protrude by a distance "d", the lateral ends 1010 of the rows 101 of the first series S1.
  • the distance "d” is between 5 cm and 50 cm.
  • the baffles 120 also protrude from the lateral edges 11 of said body. In this way, the deflectors 120 can effectively reduce the sweeps accumulated at walls M or vertical obstacles to the storage area Z2, without the risk that the body 1 comes to scrape said walls or said obstacles.
  • the deflectors 120 are advantageously in the form of brush bristles, although they may be in the form of solid blades or slats, for example flexible or rigid plastic material.
  • the bristles are all fixed on the body 1, and more particularly on the lateral edges 11 of the body 1, between the first row 102 of the second series S2 and the last row 101 of the first series S1.
  • the baffles 120 thus have a curvature which improves the guidance of the sweeps 30 to the second storage area Z2 while preventing the latter from emerging from said area. Very good results are however obtained with deflectors 120 rectilinear and / or not having curvature.
  • the baffles 120 may also be removably or not mounted on the body 1 and may be orientable in a direction substantially normal to the underside of said body.
  • each of the deflectors 120 may for example be mounted on a hinge whose axis is substantially normal to the underside of the body 1, notches or a pin for locking said deflector in the desired position. It has thus possible to adjust the opening angle "a" deflectors 120 and incidentally their amplitude.
  • the catching area of the deflectors 120 is then adjustable by the operator according to the configuration of the places to be cleaned.
  • the body 1 comprises, at its lower face, a third series S3 of longitudinal rows 103 of bristles extending in a direction substantially normal to said lower face.
  • the third series S3 is arranged behind the second series S2 and, more generally, at the rear of the body 1.
  • the rows 103 are parallel to each other, straight and parallel to a longitudinal axis L of the body 1.
  • the rows 103 may, however, to be curved.
  • the series S3 comprises four rows 103 of bristles, it being understood that it could comprise less, two rows for example only, or on the contrary more.
  • the rows 103 are spaced from each other or on the contrary contiguous. The best results are obtained when this third series S3 is present on the brush B. However, this third series S3 is not essential to obtain an effective scan, a brush B without this series can be considered as illustrated on the Figures 4 to 6 .
  • the third series S3 may possibly be associated with deflectors 130. These allow in particular to recover the smallest sweeps that would have escaped or that would have passed through the deflectors 120.
  • the deflectors 130 are advantageously located at each of the lateral ends of the row 103 of the third series S3 which is closest to the rows 102 of the second series S2.
  • the blade B further comprises at least one and, according to the example, two auxiliary rows 15 of brush bristles extending in a direction substantially normal to the underside of the body 1.
  • Each row 15 advantageously has a rectilinear shape, parallel to the longitudinal axis L having a length less than the length of the body 1.
  • the rows 15 are advantageously arranged in the concavity of the first row 101 of the first series S1 and are substantially centered relative to the latter and to the Sagittal plane S and being parallel to each other.
  • the ranks 15 avoid excessive accumulation of sweeps in the tip of the V formed by the rows 101 of the first series S2.
  • the body 1 comprises, at its lower face, another series S2 'of longitudinal rows 102' of bristles.
  • This series S2 ' has a shape similar to the second series S2, its rows 102' each having, seen from the lower face of the body 1, a curved shape (for example an arcuate shape, without breakage, an elliptical curve portion shape , ...) or in Ce or Ve, their concavity being oriented forward of said body so as to form another recovery zone Z2 '.
  • the other series S2 ' is disposed behind the second series S2 and possibly in front of the third series S3 if the latter is provided.
  • the rows of the series S2 and S2 'do not have the same length, the rows 102 being shorter than the rows 102'.
  • the length of the rows 102 of the second series S2 is less than the length of the body 1, which rows do not reach the side edges 11.
  • the rows 102 'of the other series S2' extend substantially over the entire length of the body 1 so as to reach, or at least be very close to, lateral edges 11.
  • the rows 102 'of the other series S2' can be rectilinear and parallel to the longitudinal axis L of the body 1, in a manner similar to the rows 102 shown schematically on the figure 8 .
  • the other series S2 ' By being shifted from the second series S2, the other series S2 'defines another recovery zone.
  • the other series S2 ' is associated with baffles 120' configured to return the sweeps from said second series S2 - or which escape its passage zone - to the other collection zone Z2 '.
  • the deflectors 120 ' are similar to the deflectors 120 described previously. In practice, the deflectors 120 'are located at each of the lateral ends of the row 102' of the other series S2 'which is closest to the rows 102 of the second series S2'.
  • the baffles 120 ' also protrude from the lateral edges 11 of said body, whereas the baffles 120 do not necessarily exceed them. It is therefore now the deflectors 120 'that can effectively reduce the sweeps accumulated at walls or vertical obstacles, to the storage area Z2', without the risk that the body 1 comes to scrape said walls or said obstacles.
  • the brush B now offers three collection areas Z1, Z2 and Z2 ', the storage capacity of the sweeps being reduced compared to that of the brush described in the patent document EP 2,269,484 cited above. It is understood that other series can be arranged together behind each other so as to increase the number of collection areas.
  • each of the rows 10, 101, 102, 102 ', 103 and rows 15 preferably have substantially all the same length, but do not necessarily have the same diameter as is explained in FIG. patent document EP 2,269,484 which the person skilled in the art can refer to.
  • Each row or row of bristles is constituted by a segment of a band of bristles, one end of which is held by a longitudinal head of material plastic or the like intended to be engaged in a groove C.
  • Such an embodiment of rows or rank allows replacement of rows or rows of bristles, independently of each other.
  • Such an embodiment of the rows of bristles is described in particular in the context of US Patent 5,621,940 and therefore does not require further description.
  • the brush B is implemented in the following manner.
  • the blade is adapted to the forks of the motor vehicle so that the concavity of the second series S2 is oriented towards the front of the body 1, in the normal direction of travel D of the vehicle.
  • the adaptation means 2 are designed for this purpose. Of course, it could be considered another orientation of the second series S2, for example rearward, and the matching means 2 can then be adapted to be removable, so as to allow a change in their relative orientation.
  • a driver of the vehicle adjusts the height of the forks so as to apply the bristles against the surface 3 to be brushed or cleaned.
  • This height can be chosen to be of the order of 10 to 35 cm for example and preferably of the order of 30 cm for an autonomy (wear) of several hundred kilometers on a paved surface.
  • the driver of the vehicle can also adjust the forks so as to exert a slight pressure on the bristles to arch them very slightly and allow them to adapt well to the slight irregularities of the surface to be swept. Then, the operator controls the advance of the vehicle, so that the broom B pushes in front of him the sweeps 30 present on the surface 3 to be cleaned.
  • FIGS 9 and 10 illustrate a configuration where a broom B - which does not fit within the scope of the presently claimed broom - comprises a series S0 of longitudinal rows 100 of brush bristles extending in a direction substantially normal to the underside.
  • the brush B may comprise other series of rows, for example of the type described above.
  • the rows 100 each have, seen from the lower face of the body 1, a rectilinear shape ( figure 10 ) or a curved or Ce or V shape ( figure 9 ).
  • This series S0 is associated with deflectors 120 facing the front of the body 1. These deflectors 120 are similar to those described above. Viewed from the underside of the body 1, the baffles 120 protrude from the side edges 11 of said body.
  • the deflectors 120 increase the storage capacity of the sweeps at the S0 series, the rows 110 and said baffles defining a substantial collection zone Z.
