Definitions

  • the present invention relates to a floor cleaning machine.
  • floor cleaning and drying machines for industrial or professional use are constituted substantially by a chassis which can move on the floor and supports floor cleaning means, constituted typically by at least one brush which can be actuated so as to rotate, by a device for dispensing a washing liquid, and by a suction device which draws the washing liquid and the dirt, partially drying the floor.
  • a floor wiper constituted by an elongated body which is arranged substantially transversely to the direction of travel of the machine and supports a strip of flexible material, such as rubber or the like, which is kept elastically in contact with the floor in order to allow, as the machine travels, to collect the washing liquid and the dirt removed by the action of the brush, which can thus be removed easily by the suction device, so as to leave the floor dry and clean.
  • the floor wiper is fixed to the machine chassis and typically has a considerable length, which increases its lateral footprint, so that if the machine chassis steers, regions which are wet because they are not affected by the action of the floor wiper are not left on the floor.
  • US 4158901 describes a mobile surface cleaning machine with rear mounted steerable wheels steered by a steering wheel, first and second squeegee blades pivotally mounted on each side, respectively, on the rear of the machine.
  • the floor wiper in order to avoid leaving dirty liquid residues on the floor if the machine chassis steers, the floor wiper is mounted so that it can rotate freely about an axis which is substantially perpendicular to the floor, so that when the machine steers the floor wiper automatically arranges itself laterally with respect to the machine chassis due to its friction against the floor.
  • the floor wiper in case of steering, tends to arrange itself proximate to the side of the chassis that is directed toward the inside of the turn made by the machine, with the consequence however of leaving wet the region of the floor that lies on the opposite side.
  • the aim of the present invention is to solve the drawbacks noted above by providing a floor cleaning machine which is devised particularly for use in the industrial field and can perform deep cleaning of the floor without leaving residues of dirty liquid on the floor if the machine steers.
  • an object of the present invention is to provide a floor cleaning machine which has a very simple structure and is easy to use.
  • Another object of the invention is to provide a floor cleaning machine which is capable of offering great assurances of reliability and safety in use.
  • Still another object of the invention is to provide a floor cleaning machine which can be obtained easily starting from commonly commercially available elements and materials and is further competitive from an economical standpoint.
  • the machine according to the invention comprises a chassis 2 which can move along the floor in a travel direction and supports, in a downward region, floor cleaning means 3, which can comprise for example a nozzle, not shown, for dispensing a washing liquid, at least one brush 3a which has a vertical or horizontal axis and can be actuated so as to rotate about its own axis by motor means which are supported by the chassis 2 and are not shown for the sake of simplicity, and a suction port 3b, which can be connected to a known type of suction device and allows to pick up the washing liquid and the dirt removed by the brush 3a.
  • floor cleaning means 3 can comprise for example a nozzle, not shown, for dispensing a washing liquid
  • at least one brush 3a which has a vertical or horizontal axis and can be actuated so as to rotate about its own axis by motor means which are supported by the chassis 2 and are not shown for the sake of simplicity
  • a suction port 3b which can be connected to a known type of suction device and allows to pick
  • the floor wiper 4 is mounted on the chassis 2 so that it can move along a path 4a which lies substantially transversely to the advancement direction of the chassis 2.
  • chassis 2 is provided with steering means 5 which can be maneuvered by the user to change the direction of travel of the chassis 2.
  • the steering means 5 are arranged for example at a driver's seat 6, which is preferably provided in a front region of the chassis 2, and conveniently comprise at least one steerable wheel 7, which is supported by the chassis 2 so that it can rotate about its own axis and about a steering axis which is substantially perpendicular to the floor.
  • the steerable wheel 7 can rotate about the steering axis by means of a steering element which can be maneuvered and is constituted for example by a steering wheel 8, which is connected to the steerable wheel 7 in a per se known manner.
  • the output shaft of a driving motor 7a is functionally connected by way of transmission means to the axle of the steerable wheel 7; such motor is advantageously mounted monolithically with respect to the steerable wheel 7 in its rotation about the steering axis.
  • the peculiarity of the invention consists in that it provides actuation means 10 which act on the floor wiper 4 to move it along the path 4a following an intervention performed by the user on the steering means 5 to vary the travel direction of the chassis 2.
  • the actuation means 10 are adapted to move the floor wiper 4 along the path 4a in the opposite direction with respect to the center of curvature 100 of the turn made by the chassis 2.
  • the floor wiper 4 is capable of drying the floor correctly in a region which is external to the turn made by the machine.
  • the actuation means 10 can be activated by way of the steering means 5 and are advantageously provided by providing kinematic connection means which are capable of producing a mechanical connection between the steering means 5 and the floor wiper 4.
  • such kinematic connection means comprise at least one actuation rod 11, which is functionally connected, at a first end 11 a to the steering means 5 and is connected kinematically, at a second end 11b, to the floor wiper 4.
  • the actuation rod 11 lies substantially parallel to the longitudinal extension of the chassis 2 and can perform a translational motion, in one direction or the other, along its own axis with respect to the chassis 2 in order to move in one direction or the other the floor wiper 4 along the path 4a in response to an intervention of the user on the steering means 5.
  • first elastic return means 12 act on the actuation rod 11 and are adapted to contrast the axial translational motion of the actuation rod 11 at least in one direction.
  • the first elastic return means 12 are constituted for example by a helical spring 13, which is arranged around the actuation rod 11, between an annular shoulder 14, which is rigidly coupled to the actuation rod 11, and an eye 15, which is fixed to the chassis 2 and slidingly supports the actuation rod 11.
  • the floor wiper 4 is connected to the chassis 2 by way of a pair of linkages 16, which lie substantially parallel to each other and are articulated, at one of their ends, to the chassis 2 and, at their other end, to a respective end portion of the floor wiper 4.
  • the actuation means 10 of the floor wiper 4 comprise at least one actuation arm 17, which is pivoted to the chassis 2 about an oscillation axis which is substantially perpendicular to the floor and is functionally connected, with one of its end portions, to the floor wiper 4.
  • the actuation arm 17 is capable of performing on command, following an intervention performed on the steering means 5, an angular movement about its own oscillation axis in the same direction as the turn imparted to the chassis 2 by the steering means 5 and more precisely as the direction of rotation actuated to the steerable wheel 7 about its own steering axis, to steer the chassis 2.
  • the actuation arm 17 engages conveniently between the prongs of a fork-like element 18, which is connected to a central region of the floor wiper 4 so that it can rotate about a pivoting axis which is substantially parallel to the oscillation axis of the actuation arm 17, in order to allow the movement of the floor wiper 4 along the path 4a when the actuation arm 17 rotates about its own oscillation axis.
  • the steerable wheel 7 is adapted to act on the first end 11 a of the actuation rod 11 to produce a translational motion of the actuation rod 11 along its own axis following a rotation performed by the steerable wheel 7 about its own steering axis.
  • the actuation rod 11 is provided, at its first end 11a, with an engagement head 19, which protrudes with respect to the axis of the actuation rod 11 toward the steerable wheel 7 and is provided conveniently with a gliding wheel 19a.
  • abutment means which are designed to engage the first end 11a of the actuation rod 11 and more particularly its engagement head 19 so as to push axially on the actuation rod 11 in one direction or the other depending on the direction of rotation imparted to the steerable wheel 7 about its own steering axis when the chassis 2 is steered.
  • such abutment means are provided by providing a structure 20 which is connected monolithically to the steerable wheel 7 in its rotation about the steering axis and substantially defines, in points which are diametrically opposite with respect to the axis of the steerable wheel 7 and on opposite sides with respect to its steering axis, two abutment surfaces 21 which are directed toward each other and can engage selectively against the engagement head 19 of the actuation rod 11 depending on the direction of rotation imparted to the steerable wheel 7, about the steering axis.
  • the structure 20 has an elongated plate 22 which lies substantially at right angles to the axis of the steerable wheel 7 and to its steering axis and has two folded end portions 22a, 22b, which protrude with respect to the plane of arrangement of the remaining portion of the elongated plate 22 in the opposite direction with respect to the steerable wheel 7 and define, with their mutually facing faces, the abutment surfaces 21.
  • the folded end portions 22a, 22b are inclined and mutually converge toward the steerable wheel 7.
  • the engagement of the abutment means against the engagement head 19 of the actuation rod 11 can occur for example after exceeding a preset angle of rotation of the steerable wheel 7 with respect to its non-steered position which allows the chassis 2 to travel in a straight line, so as to exclude the intervention of the actuation means 10 on the floor wiper 4 in case of turns of the chassis 2 with a limited steering angle.
  • the actuation rod 11 is advantageously connected to lever means which act on the actuation arm 17 to produce, following an axial translational motion of the actuation rod 11 produced by a rotation about the steering axis of the steerable wheel 7, an angular movement of the actuation arm 17 about its own oscillation axis in the same direction as the rotation performed by the steerable wheel 7 about its own steering axis.
  • lever means comprise a first lever 23, which is pivoted, at one of its ends, to the second end 11b of the actuation rod 11 and, at the other end, to the chassis 2, and a second L-shaped lever 24, which is pivoted, with an intermediate region, to the chassis 2 about an articulation axis which is substantially perpendicular to the floor.
  • the second lever 24 can rotate about its own articulation axis in contrast with second return means, which are connected between the second lever 24 and the chassis 2 and are constituted for example by a torsion spring 25 which is arranged on the pivot of the second lever 24.
  • the second lever 24 is pivoted with one side 24a of the L-shape to an end of a linkage 26, which is articulated, at its other end, to an intermediate portion of the first lever 23 and is conveniently adjustable in length by means of threaded elements.
  • the other side 24b of the second lever 24 advantageously has a fork-shaped free end 27 which straddles the actuation arm 17 in order to engage it rigidly in the rotation of the second lever 24 about its articulation axis.
  • the floor wiper 4 is in a substantially centered position with respect to the rear part of the chassis 2, as shown in Figure 3 .
  • the first lever 23 performs a rotation about its own fulcrum, which is connected to the chassis 2, so as to actuate, by way of the linkage 26, the second lever 24 so that it rotates about its own articulation axis, overcoming the action of the torsion spring 25.
  • the action of the torsion spring 25 on the second lever 24 allows to return the actuation arm 17 automatically to its initial position and consequently return the floor wiper 4 to its centered position.
  • the materials used, as well as the contingent shapes and dimensions may be any according to requirements.
