Definitions

  • the present invention relates to a floor cleaning machine.
  • Floor cleaning machines which are equipped with a brush that rotates about a vertical axis and are provided with at least one nozzle for dispensing a washing liquid.
  • these machines have a squeegee, which is arranged in a rear position with respect to the brush along the forward travel direction of the machine and slides in contact with the floor, allowing to collect the washing liquid and the dirt removed by the action of the brush so that they can be picked up by an intake, associated with the machine, so as to leave the floor dry and clean during the forward travel of the machine.
  • This type of machine suffers the drawback that when it is moved backward, i.e., in the opposite direction with respect to their normal forward travel direction, they leave the floor wet, since the squeegee is unable, in this situation, to collect the washing liquid released by the dispensing nozzle.
  • the aim of the present invention is to solve this drawback, by providing a floor cleaning machine that allows the squeegee to collect the washing liquid and dirt even when the machine is moved in the opposite direction with respect to its forward travel direction.
  • an object of the invention is to provide a floor cleaning machine that can be practical to use for the user.
  • Another object of the present invention is to provide a floor cleaning machine that has an extremely simple structure.
  • a floor cleaning machine designated generally by the reference numeral 1, comprises a supporting structure 2, which has, along a forward travel direction 3 of the machine, a front part 2a and a rear part 2b.
  • the supporting structure 2 on its side directed toward the floor 100, supports a brush 4, which can be actuated by motor means 5 with a rotary motion about a rotation axis 4a that is arranged, during use, substantially vertically.
  • the brush 4 can, for example, be constituted by a disk 6a that can be coupled detachably to the actuation shaft of the motor means 5.
  • Bristles 6b are anchored to the disk 6a and are intended to act by friction on the floor 100.
  • one or more nozzles for dispensing a washing liquid can be associated with the supporting structure 2.
  • a squeegee 7 is further associated with the supporting structure 2 and is located in the rear position with respect to the brush 4 along the forward travel direction 3 of the machine.
  • the squeegee 7 is formed as usual by an arc-like supporting body 7a, which is extended around a portion of the brush 4 and to which one or more flexible laminas 7b, intended to slide on the floor 100, are coupled.
  • the squeegee 7 is mounted so that it can rotate about an oscillation axis that is substantially parallel to or, more preferably, substantially coincides with the rotation axis 4a of the brush 4.
  • connection means 8 which can be activated on command and are adapted to integrally associate the squeegee 7 with the brush 4, so that the squeegee 7 can be turned by the brush about its oscillation axis, so as to move the squeegee 7 from the position behind the brush 4, along the forward travel direction 3 of the machine, to a diametrically opposite position, in which it is arranged in practice in front of said brush, again along the forward travel direction 3 of the machine.
  • connection means 8 can be activated by tilting the supporting structure 2, lifting its front part 2a from the floor 100, with respect to its rear part 2b, as shown in particular in Figure 8 .
  • this tilt of the supporting structure 2 can be achieved by the user by using as a lever an elongated handle 20, which rises upward from the rear part 2b of the supporting structure and by pivoting on wheels 21, conveniently associated with the rear part 2b of the supporting structure 2, in a position that lies behind the assembly constituted by the brush 4 and by the squeegee 7.
  • the user by pushing downward on the grip end 20a of the handle 20, can rotate the supporting structure 2 around the region of contact with the floor 100 of its rear part, constituted by the wheels 21, so as to raise from the floor its front part 2a with respect to its rear part 2b, as shown by way of example in Figure 3 and in Figure 8 .
  • stop means are also provided which are adapted to stop the rotation performed by the squeegee 7 integrally with the brush 4 when the squeegee 7 is located at the front position, preventing it from continuing beyond in rotation.
  • the stop means can be constituted by a resting surface, which is formed in the front part 2b of the supporting structure 2 and is intended to be engaged by abutment by a portion of the squeegee 7.
  • the squeegee 7 conveniently is connected to an end of a supporting arm 9, which is pivoted, at its other end, to the supporting structure 2 about the oscillation axis of the squeegee 7.
  • connection means 8 comprise a friction body 10, which is supported by the supporting arm 9 and is adapted to make contact with the brush 4, following the activation of the connection means 8, so as to integrally couple the supporting arm 9 and therefore the squeegee 7 with respect to the brush.
  • the supporting arm 9 can rotate with respect to the supporting structure 2 also about an articulation axis 9a that is substantially perpendicular to said oscillation axis of the squeegee 7, in order to allow the friction body 10 to pass from an inactive condition, shown in particular in Figure 2 , in which it is disengaged from the brush 4, when the supporting structure 2 is in a position that is not inclined with respect to the floor, to an active condition, in which the friction body 10 is supported in contact with friction against the brush 4 when the supporting structure 2 is moved to an inclined condition with lifting of its front part 2a from the floor 100 with respect to its rear part 2b and vice versa.
  • the friction body 10 is arranged so as to face the upper face of the disk 6a of the brush 4, so as to be able to make contact with it when it is in its active condition.
  • the friction body 10 can be made of elastically yielding material, such as for example rubber or the like, and for example can be fixed to the supporting arm 9 by means of a threaded portion 10a, which is integral therewith and can be engaged by a locking nut 10b.
  • the motor means 5 of the brush 4 are activated so that it can move with a rotary motion about its own rotation axis 4a.
  • the brush 4 acts progressively on the various regions of the floor 100, removing the dirt that is present with the aid of the washing liquid emitted by the dispensing nozzles, and the squeegee 7 collects the washing liquid and the removed dirt.
  • the supporting structure is in a condition that is not inclined with respect to the floor 100 and the friction body 10 is spaced from the brush 4 and accordingly the squeegee 7 is uncoupled with respect to the rotation of the brush 4.
  • the user wishes to move the supporting structure 2 in the opposite direction with respect to the forward travel direction 3, he/she first of all tilts the supporting structure 2 so as to raise its front part 2a from the floor 100 with respect to the rear part 2b, pivoting on the wheels, as shown in Figure 8 .
  • the brush 4 and the squeegee 7 rise from the floor 100 and, by losing contact with the floor 100, rotate, due to its own weight, the supporting arm 9 about the articulation axis 9a, with consequent approach of the friction body 10 to the disk 6a of the brush 4 until the friction body 10 makes contact with the disc 6a of the brush 4.
  • the squeegee 7 is turned by the brush 4 about its own oscillation axis, thus moving from the position behind the brush to the position in front of said brush, remaining in this position thanks to its retention caused by the stop means.
  • the user can return the supporting structure 2 to a non-tilted condition, lowering again the front part 2a of the supporting structure 2 and then, as shown in Figure 9 , can move the machine in the opposite direction with respect to the forward travel direction 3, the squeegee 7 being always able to operate in a position that lies behind the brush 4.
  • the invention is capable of achieving fully the intended aim, since it allows to clean the floor both by making the machine travel in its normal forward travel direction and by moving it in the opposite direction.
  • the materials used may be any according to requirements.
