Definitions

  • the present invention relates to a floor cleansing machine, particularly for industrial use.
  • floor cleansing and drying machines for industrial or professional use are constituted substantially by a mobile chassis which supports floor cleansing 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.
  • the chassis of the machine is provided, on its front portion, with a driver's seat which can be occupied by the user and is provided in a downward region with two rear lateral wheels, at least one of which is a driving wheel, and with a steerable front central wheel, which can be usually controlled by the user by means of a steering system located at the driver's seat.
  • the foot resting platform of the driver's seat is arranged at a rather high level with respect to the ground and can be accessed by the user from a lateral region of the chassis of the machine.
  • the drawback of this configuration consists mainly in that when the user climbs in or out of the driver's seat, the chassis of the machine tends to tilt sideways under the action of the weight of the user, with the risk that it might overturn, in practice falling onto the user.
  • machines structured in the manner described above do not have adequate lateral stability and therefore may tip when turning, with consequent physical injury for the user.
  • the aim of the present invention is to provide a valid solution to the problem described above by providing a floor cleansing machine, particularly for industrial use, which has a greater lateral stability than currently known ones both when turning and when the user climbs in or out of the driver's seat.
  • an object of the present invention is to provide a floor cleansing machine which is capable of absorbing adequately the stresses which, due to unevenness of the ground, can be transmitted to its chassis during movement.
  • Another object of the invention is to provide a machine which can be obtained easily starting from commonly commercially available elements and materials and is further competitive from an economical standpoint.
  • a floor cleansing machine particularly for industrial use, which comprises a chassis which supports floor cleansing means in a downward region, said chassis defining a driver's seat and being provided at the rear with at least one pair of lateral wheels and at the front with a steerable central wheel, characterized in that said chassis is provided with at least one pair of auxiliary lateral ground supports which are arranged on mutually opposite sides with respect to said steerable central wheel.
  • the machine according to the invention generally designated by the reference numeral 1, comprises a chassis 2 which supports, in a downward region, floor cleansing means 3, which can be of any per se known type.
  • the floor cleansing means 3 can comprise for example a nozzle for dispensing a washing liquid which is directed toward the floor, at least one brush 4 which has a vertical or horizontal axis and can be turned 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 5, which can be connected to a known type of suction device, which is accommodated within the chassis 2 and allows, in cooperation with a floor wiper 6, to pick up the washing liquid and the removed dirt.
  • the dispensing nozzle is connected, by means of a pump, to a tank for containing the washing liquid, which is preferably located at the rear part of the chassis 2.
  • the chassis 2 defines, in its front portion, a driver's seat 8 which can be occupied by the user in order to maneuver the machine.
  • the chassis 2 On its underside, the chassis 2 is further provided at the rear with at least one pair of lateral wheels 9, at least one of which is conveniently a driving wheel, being connected to an actuation motor, typically of the electric type, which can be controlled from the driver's seat 8 by way of appropriately provided control devices 10 which are per se known.
  • actuation motor typically of the electric type
  • a steerable central wheel 11 which is connected to a steering device provided for example with a steering wheel 12 arranged at the driver's seat 8.
  • the chassis 2 is provided with at least one pair of auxiliary lateral supports 13, which can engage the ground so as to glide over it and are located on mutually opposite sides with respect to the steerable central wheel 11, so as to provide in practice, for the chassis 2, additional supporting points which are capable of contrasting effectively the lateral imbalance of the chassis 2 when the user climbs in or out of the driver's seat 8 or during very tight turns performed at a substantial speed.
  • the auxiliary lateral supports 13 are constituted respectively by at least one supporting wheel 14.
  • each supporting wheel 14 is mounted so that it can rotate freely about a substantially vertical axis, so as to follow automatically the changes of direction of the machine during use.
  • shock-absorbing means which are designed to absorb the stresses transmitted by the supporting wheels 14 to the chassis 2 due to the unevenness of the ground.
  • shock-absorbing means are provided by elastically yielding means 15, which are designed to maintain the respective supporting wheel 14 in contact with the ground, in order to ensure higher safety against lateral overturning of the chassis 2.
  • the elastically yielding means 15 are constituted by a Belleville spring.
  • the invention fully achieves the intended aim, since it allows a safer use of floor cleansing and drying machines thanks to the auxiliary lateral supports, and a more comfortable use thereof in steering, thanks to the shock-absorbing means which act thereon.
  • the materials used, as well as the contingent shapes and dimensions may be any according to requirements.
