Abstract

The invention relates to the design of a machine making it possible to mechanize the operations of cleaning floors, walls and ceilings by bringing together on a tool, inside a suction casing, one or more brushes in rotary motion or back and forth in which is injected a liquid for washing or rinsing. One variant makes it possible to treat small or difficult-to-access surfaces by assembling the motor elements on a trolley with swiveling casters and by maneuvering the tool using a telescopic suction tube, the other to treat large surfaces by fixing the tool on an articulated arm which is itself fixed with the driving elements on a carriage with driving and steered wheels. The machine according to the invention is particularly intended for cleaning floors, walls and ceilings.

Description

1 2 2633176

  The present invention relates to the design of a machine

  not allowing leaching, rinsing and drying of soils,

walls and ceilings.

  They are machines for soil leaching, but they are suitable only for industrial use, and moreover, these machines are not usable on walls and ceilings. Traditionally, small area soils are leached manually using a scrubbing brush and dried with a mop; as for the walls and ceilings, they are washed manually by means of a

  Sponge. These operations are long and painful, especially

for the plifonds.

  L_. machine, according to the invention, overcomes these disadvantages. The combination of different equipments and tehnrlq-ues assembled and implemented simultaneously allows the

  handling of leaching, rinsing and drying operations.

  The general p-incipe is based on the design of a tool

  which brings together the functions of brushing and water injection to-

  the inside of a suction housing. The tool is composed of

  2: o o o o, o-brushes, hollow inside, and perforated between 3 poi3 s, to allow the passage and injection of water, L and d'uLn suction housing for water recovery lersivage or rinsing around the or brushes, and thus allow work on both vertical surfaces

2c than horizontal.

  ULr-e pump injects water added with detergent for the leaching operation, or pure water for the rinsing operation in the (the) brush (s) in motion. An induL-triel type vacuum cleaner specially designed for the recovery of

  _0 3i.quides, collect the e-u on the edge of the brush (s).

  After being filtered into the bottom of the tank

  the vacuum cleaner on a strainer, the water is pumped and reinjected.

  The complementary drying operation is done by brushing

and suction without water injection.

  The movement of the brush (es) is either rotary or back-and-forth. In the case of a rotary movement, the brawl (s) is (are) round and has (s) a central stem

  hollow, from the hollow part of the brush to the

  these water inlet made on the catês of this rod.

  This rod thus makes it possible: to fasten the bridging on rollers to sealed balls or in a rotating cage; the transmission of the movement by connecting the end of this rod to a flexible gimbal connected to an engine;

  - and the water supply of the brush.

  If the tool has several round burries, the movement is transmitted on the stem of one of them by the cardan (IblE, then communicated to; Others, the outer base of each of these b-bosses being designed e-. notched wheel and forming 2-thus paraelleal gears. The bearings. sealed balls. or the rotation cages are housed or formed in

  the thickness of the suction housing.

  The rods of the brushes that are not connected to the flexible gimbal are hollowed out to the end to allow direct entry of the water without holes on the sides. In this ca., a channel! formed in the crankcase, allows feeding in

  water from all the b'-osses. The channel, or the cavity for the

  tls- to one brcs-se, is rac-ordè by a hose to the

  This leg has a hole, from its hollow cylindrical portion up to the hollow portion of the brush, over a length equal to the back and forth movement to allow

  thus the passage of water regardless of the positiorn of the brush.

  The housing provides several functions. It serves both as a support for the brushes, by the rotation cages of the rods, by the bearing housings, or by the notches intended to receive the ejects of the holding and sliding tubes. ; - from channeling the water to the rods of the brushes and fitting for the hose of the pump:

  The accompanying drawings illustrate the invention.

  Figure 1 shows a top view of the tool.

  In the housing (1), made of plastic in

  several molding operations, the suction outlet port

  tion (2) is perpendicular to the base and provided for connection of the suction hose (39). The 3 flats of the tool (5) are molded with the casing and the inside is threaded to allow the screwing of the shock absorbers (44 to support the tool on a tle-o foot.

  lower the water down for better recovery

  tion of the breathing orifice during vertical work.

  The Figure shows in section the tool to demonstrate its operation. The housing (1) is flared, from its base to the suction port (2). In the housing, the brush (8), whose end of the rod (5) is designed to be adapted to a flexible gimbal, can rotate while being supplied with water. Indeed, from the hollow part of the brush (10) to the recess (11) made in the housing, the rod

of the brush is ct-ese.

  At the recess (11) made in the housing, the rod has orifices (12) formed on its sides. Figure 4 illustrates these orifices by showing in cut-off profile this

  part of the brush rod. Water can therefore move from

  cord (4) of the hose (35) in the recess (11) of the

  casing, through the o-holes (12) of the rod, in the hollow part

  from the stem, then into the hollow part of the brush (10)

  to be injected through the bristles through the orifices (1--).

  The base of the housing is rectangular in shape like the brush. The suction outlet of the housing is horizontal for

  than suction (38). In this housing are fixed 2 tubes (20 and 21) by their ends in notches provided for this purpose in the

  casing. These tubes can be made of metal, aluminum

  minium! or even very rigid plastic material. The assembly is made by interlocking by forcing. These 2 tubes serve as

  brush holder - which, thanks to its 4 molded legs, whose inte-

  is cylindrical and adapted to the diameter of the tubes, can

  and slide to achieve a movement back and forth.

  The movement is obtained using a mini rod cylinder (22)

  powered by 2 small hoses ('23) connected to the electri-

  fixed trovanrnes on the trolley. The tube (21) is connected by a T to the water inlet (4). Inside a sliding lug (24) of the brush, the tube is pierced with a bottom orifice (25) downwards as well as inside the 2C 'lug (24) of an orifice ( 26) on a corresponding length

to the movement of the brush.

  The same tool is feasible in self-supporting version.

  In this case, the suction outlet (2) is perpendicular to the base of the housing and allows the direct connection of a suction hose (3I9). The housing is provided with 35 fixing lugs (3) to allow it to be held by means of 5 dampers (44) fixed on a telescopic stand mounted on

  steerable castors or an arm articulated by jacks.

  I 0 This works in a back-and-forth motion. The system for fi ltering and feeding water to the brush is identical to the tool described in; Fig. 10 to 14. Far countered the movement is

  obtained by means of a connecting rod (27) connected by an end

  to. the brush on a rod (28), on a bearing, and at the other end, also on a bearing, - eccentrically to a wheel. The ticge of the wheel is also mounted on a bearing and the suction housing and the end of this rod connected to a flexible gimbal.
