  MACHINE FOR MAINTAINING SURFACE MAINTENANCE

  PLANES, IN PARTICULAR SOIL CLEANING.

  The invention relates to an improvement to the

  China which is the subject of French patent No. 75/32 557 (published under No. 2,328,439) in the name of the Applicant. The machine which is the subject of the aforementioned patent and which makes it possible, in particular, to ensure the maintenance of flat surfaces, such as floors, essentially comprises: at least one mobile friction member whose active elements are able to come in contact with the surface to be treated

  means for supplying a liquid for treatment

  at the points of contact of said active elements with the surface;

  - means to ensure aspiration and elimination

  nation of the majority of undesirable substances

  the surface, and in particular such substances

  jointing with at least part of the treatment liquid

  which, together with the action of the elements

  the movable member to detach them from said surface

  this; means for sealing the suction means when the latter are in the working position; means connected to the suction means, for storing the spent liquid; means for manually directing the machine during work and for moving it, said machine being characterized in that the suction means and, where appropriate, the corresponding sealing means, are located with respect to a direction of the machine, both in the front and at the rear of the machine, so that the means

  front suction chambers capture dry substances

  these to eliminate no or little adherent to the part of the - 2 -

  surface treated, whereas those located in the back-

  together with the aforesaid liquid, recover the substances

  these more adherent to said surface from which they have been separated, under friction, in the presence of said liquid and while ensuring at least partial drying of said surface, the reverse occurring when the machine

is moved in the opposite direction.

  Such a machine, very manageable, relatively little

  cumbersome, gives complete satisfaction and makes it possible

  perform both dry dusting and dechil-

  wet scrubbing of adhering soil

  the ground in a particularly com-

fashion, fast and efficient.

  Now, it has been found, and this is the subject of the present invention, that it was possible, while

  retaining the essential characteristics of

  a number of adaptations that make it useless

  It is even easier and above all to reduce its size, to improve its stability and to have tanks, both storage liquid treatment and recovery after washing, larger. In general, the invention therefore relates to a machine of the type which is the subject of the aforesaid French patent which comprises, mounted on a chassis equipped with means (wheels) to ensure its displacement: two suction assemblies spaced from each other on said frame and allowing the use of the machine both in one direction and in the other;

  - two brushes (or similar) rotating inside

  in a housing where the control motor of said brushes is located;

  - two bins, one of which is intended to contain the

  treatment, the other to recover said impurity-laden liquid after cleaning; - 3 - - a suction turbine and - means to ensure the supply of

  electrical current of the various organs, means

  be constituted by a cable stored on a winding

  mounted on the machine and allowing connection

  to an external source of electricity, either by means of bat-

  or equivalent mounted directly on the chassis and making the assembly autonomous, and is characterized by the fact that the chassis is realized

  so that the suction organs and bros-

  its processing and its drive motor can be read, the masses' of the various elements

  this machine (motor, turbine, coil,

  their cable or battery) being disposed substantially along the longitudinal axis of the machine, so that the center of gravity is as low as possible and the assembly has a very high stability and maneuverability. Furthermore, according to one embodiment, the

  frame of the machine is made of two separate parts

  rables, the front part including the squeegees, the brushes and their motor as well as the recovery tank

  wastewater, and the other part used to manipulate the

  said machine supporting the supply of liquid treatment-

  the suction turbine and the winding system

  power supply cable.

  Of course, said machine can be designed from

  so that the chassis is monobloc while preserving

  the aforementioned arrangement for the driving members, the brushes, the winding system and the bins receiving the liquid, so as to obtain a set

particularly compact.

  The invention and the advantages that it brings will, however, be better understood thanks to the exemplary embodiment given hereinafter as indicative but not limiting and

  FIG. 1 is a perspective view of the

  appears from a machine made in accordance with the

  tion; FIG. 2 is a detailed partial exploded view of the active part of a machine according to the invention, that is to say of the one comprising the engine block, the brushes and the means for front and rear suction; FIG. 3 is a detailed view of the part of the machine used for its maneuver and which comprises the

  suction turbine and the means of storage and

  electric power cable bearing; FIG. 4 is a detail view, also in perspective and partly exploded, of a cable winder particularly suitable for a

machine according to the invention.

  If we refer to the annexed diagrams and more

  particularly in Figure 1, the cleaning machine

  according to the invention consists essentially of two

  sembles, connectable to each other, one, referenced

  (1) and illustrated in detail in Figure 2, supporting

  sensitively the active elements of the machine (as-

  drawing, brush ..), the other referenced (2) and illustrated in detail in Figure 3, showing in detail the part of

  the machine used to maneuver it.

  If we refer to these figures 1, 2 and 3, the

  tie (1) consists essentially of a carrier chassis

  (3) equipped with wheels (4) for moving the assembly.

  On this carrier frame (3) is mounted an internal frame

  mediaire (5) or machine frame on which are fixed the two suckers (6, 7) associated with means (8,9) for sealing. These suckers can be reversed, their control being achieved by means of a pedal (10) acting on

_- 5 _-

rods (11).

  The frame also supports the engine block or housing supporting the brushes (not visible in these figures). In this case, the brushes are two in number, are cylindrical and are driven by a toothed belt by means of a variable speed motor (13).

  In addition, resources are provided for this structure.

  sis to allow the lifting of the engine block (13) as well as that of the suckers. These means (see Figure 2) consist essentially of cams (14,15) operated by a pedal. The lifting of the engine block (13) itself is also achieved by means of cams (36,37) actuated by rods (38) themselves controlled by a pedal (39). On the front part (1), is also mounted the

  recovery tank (27) of the polluted waters which are

  pirated by the stern nozzle (if we consider the meaning

in advance of the machine).

  The recovery of dust and wastewater is carried out using two pipes connecting each of the front and rear squeezers (6,7) to the inlet of the tank (27). Dust and water arrive at the top of

  the vessel, which preferably has fine baffles

  at each entrance under the cover. A third suction inlet is located in the second tank inside the large tank, a metal filter being provided for filtering dust that could come into this second tank. The vacuum of this tank is by a turbine driven by a motor and which is

  connected to the tank by a suction pipe.

  The control assembly (2), illustrated in detail in Figure 1, also consists of a frame. So

  chassis, are mounted two wheels (17,18). In addition

  - 6 - their, this frame supports the winding system (19)

  which will be seen in more detail later in the description.

  and illustrated in Figure 4 as well as the suction turbine (20). Moreover, on the two uprights (21,22), is mounted the feed tank (23)

in treatment liquid.

  All the important masses that such a

  the machine, namely the engine block (13), the reaction vessel

  wastewater (27), the turbine (20), the cable winding system (19) and the distribution vessel (23) are mounted in such a way that they are distributed along the longitudinal axis of the machine. Such a way allows to obtain a very

great stability.

  With particular regard to the dispensing tank

  tion (23), not illustrated in detail, it is found

  inside a hood (24) (see Figure 1)

  the steering arm proper (21,22). Even-

  it could be mounted directly on the

frame.

  The inlet of this tank (23) is provided with a metal filter and the distribution of the water, added with detergents, is carried out using a mechanical valve (ball valve) and the opening or closing are controlled by a lever connected to the valve by a

mechanical means.

  The water descends only by gravity. Otherwise,

  on the housing a quick coupling (25) is

  both the disengagement of the two parts (1) and (2) of said machine and, as said before the system for winding the cable (26) supply

Electric power.

  Such a winder is illustrated in detail in Figure 4 and is also part of the invention. In this embodiment, it is fixed, as is apparent from FIG. 3, on the steering frame (2).

  below the feed tank (23).

  Optionally, it could be set back in the back. This winder (19) consists essentially of a hollow plastic spool, equipped with two

  lateral flanges (27,28). This coil is mounted

  nante on an axis (29) fixed on the uprights (30,31) of the steering chassis. It also comprises a set of rings (33), fixed, mounted on the axis (29) and a set of brush holder (34) mounted on the outer flange (28) by means of a fixed pin (35). ). Of course, an insulation layer (tube) is provided between the axis (30) and

the brush holders.

  Compared to the machine covered by the patent

  2,328,439, such a machine has many advantages.

  and can be used in different ways.

  First of all, it can be used as

  than a vacuum cleaner with front and rear suction and bros-

  wise of the ground in a single passage. In such a case, it sucks the dust, lava and decape, sucks the waters

used and dries said soil.

  It can also be used as a

  peuse-waxy-polisher. In such a case, only the engine block equipped with brushes, disk carrier with discs suitable for each

work to be done.

  Optionally, it can be used as a vacuum cleaner water and dust. This is possible by connecting a hose to a suction inlet of the recovery tank and obstructing the other by a plug, said hose can be extended with a rod equipped with appropriate dumps according to uses.

  In addition, such a machine has a very large

  stability and is very manageable, especially when it is performed in two parts coupled because then it

  It is possible to modify the inclination of the

  (ie by rotating it from 45 to 90 towards the front part), thus reducing the floor area and thus reducing the overall size, which allows maneuvering according to a

low radius of curvature.

  Of course, the invention is not limited to the embodiment described above but it covers all variants made in the same spirit. Thus, such a machine can be made not in two parts that can be decoupled one of

  the other, but in one and only part.
