Definitions

  • This invention relates to improvements in motor sweepers used for cleaning indoor and outdoor surfaces and floors in general.
  • motor sweepers have been widely used for some time, they comprising essentially a frame with a driver compartment below which there are provided at least one front lateral conical brush, a steerable wheel to the rear thereof, a rearward-lying transverse horizontal cylindrical brush, two drive wheels to the rear thereof, and a rear collection bin for the dirt collected by the cylindrical brush.
  • Modern motor sweepers comprise two opposing front conical brushes which are adjustable in height, and are each provided with an electric drive motor which rotates them in such a manner as to convey the dirt towards the longitudinal axis of the machine, and hence towards the cylindrical brush.
  • each conical brush is located at the end of a horizontal arm branching from a vertical shaft which is axially slidable for adjusting the height of the brush, and is connected to the frame by an elastic positioning member, such as a spring.
  • the purpose of said elastic member is to prevent the respective lateral brush, and the elements associated with it, from undergoing damage on sudden collision with fixed structures, such as a pavement.
  • said elastic member maintains the lateral brush swung outwards, where it rests against a limit stop and where, typically with reference to straight-line advancement of the machine, it becomes partly superposed on the corresponding end of the rearward-lying cylindrical brush, and extends beyond it.
  • the lateral brush collides against an obstacle, it retracts against the force of the elastic member, to then automatically return into position when said obstacle has been overcome.
  • the cleaning face of the machine defined by the lower portions of the cylindrical brush and of the lateral brushes in contact with the surface to be swept, is in fact noncontinuous in contast to the case when the machine travels in a straight line or confronts curves which are not particularly narrow, in which each lateral brush is partly superposed on the corresponding end of the cylindrical brush.
  • the main object of the present invention is to obviate the aforesaid within the context of a simple, rational and reliable construction.
  • said object is attained, within the context of a motor sweeper as defined in the introduction, by interposing between the machine steering unit and the support structure for said at least one lateral brush, a member which is normally insensitive to the operating positions of the lateral brush and of the steering unit, but which, when the machine confronts a curve involving a steering angle exceeding a predetermined value, causes that lateral brush situated on the outside of the curve to swing inwards.
  • said inward swing takes place against the force of the elastic means for repositioning the brush, or in other words, rearwards with reference to the travelling direction, with consequent approach of the lateral brush to the facing end of the rearward-lying cylindrical brush.
  • Said predetermined value corresponds to that steering angle at which the inner point of contact between the ground and that lateral brush situated on the outside of the curve is no longer superposed in the direction of the travel trajectory on the point of contact between the ground and the facing end of the cylindrical brush, but is spaced from it towards the outside of the curve.
  • Said member preferably consists of a connecting rod which at one end is pivoted to the ring gear controlling the direction of the steerable wheel, and at the other end presents a slot with which a pin associated with said support structure for the lateral brush is slidingly coupled.
  • said pin is carried by a lever branching from the vertical shaft which supports the lateral brush, and with which said lever is torsionally but not axially engaged.
  • Figure 1 is a transparent partial plan view from above showing the front right part of a mechanical sweeper according to the invention in its straight-line travel configuration.
  • Figure 2 is a view in the direction II of Figure 1.
  • Figure 3 is a view on a smaller scale totally similar to that of Figure 1, showing the machine again in straight-line travel but at the moment in which the right lateral conical brush collides against an obstacle.
  • Figure 4 is a view similar to the preceding, showing the machine at the moment in which it confronts a curve towards the right with maximum steering angle.
  • Figure 5 is a view totally similar to that of Figure 1, showing the machine at the moment in which it confronts a curve towards the left with a steering angle close to the value at which the means of the invention intervene.
  • Figure 6 is a view similar to the preceding, showing the machine completely steered towards the left, with intervention of the means of the invention.
  • the wheel 2 is rotatably mounted on a fork 3 connected to the frame via the thrust bearing 4.
  • a fork 3 connected to the frame via the thrust bearing 4.
  • Said ring gear 5 is provided with two salient peripheral pins 6, described hereinafter, which with the machine in straight-line travel configuration (see Figures 1 and 3) are symmetrically disposed about the longitudinal axis thereof.
  • a box arm 14 To the lower end of the shaft 8 there is projectingly fixed a box arm 14, the free end of which supports an electric motor 140 for rotating the brush in the direction of rotation indicated by A in the figure, via the perpendicular transmission indicated by 15.
  • levers 12 and 13 respectively, forming overall a lever of rocker type.
  • the first lever 12 is connected to the frame 10 via a tension spring 120, and is provided with an abutment 121 arranged to rest against an adjustable threaded end-of-swing push rod 122.
  • the second lever presents a salient pin 60 received, as a precise free-sliding fit, within a terminal longitudinal slot 61 in a connecting rod 62, which at its opposite end is pivoted on the right pin 6 of the steering ring gear 5.
  • said slot 61 has a length such that the position of the connecting rod normally does not modify in any manner the operating configuration of that part of the machine illustrated, the connecting rod 62 remaining inactive until the value of the steering angle of the wheel 2 exceeds the predetermined value defined in the introduction, beyond which it retracts inwards and rearwards that brush 1 which at that moment is situated on the outside of the curve.
