Description

-D E S C R I PTION-

  The present invention relates to a disc capable of

  be driven in rotation by motorized track, provided with a (de) dispo-

  cleaning agent (s) and fitted to a floor cleaning machine equipped with a tank containing a cleaning liquid and / or water, as well as a tubular conduit which leaves from the tank, is directed towards the face posterior of the disc and ends at a distance from the latter, in a region situated between the median axis of the disc and a circumferential line of this disc, on which several perforations are made through

  said disc, above which is formed an accumulator ring

  lation which surrounds the perforations in an external position relative to the median axis of the disc; which represent,

  on its marginal ridge facing away from the posterior surface

  re of the disc, a circumferential collar for intercepting liquid, essentially oriented radially with respect to

  the center line of the disc; and which has areas of wall sail-

  lant in the direction of the perforations of the disc, which can possibly be fitted into these perforations, respectively arranged in the vicinity of a perforation, and forming a rim

accumulation.

  A disc of this kind is known from patent DE-C2-

  41 40 853. Although the realization, known from this document,

  has proven itself in the state of the art, a

  deny, affecting the known disc, was found to reside in the

  fact that the latter can be operated in only one direction of rotation

  tion, in accordance with its intended purpose, and that the user must therefore employ different embodiments of the

  disc depending on the direction of rotation of the motor drive

  laughed. Based on this prior art, the object of the invention is to provide a motorized rotary disc of the type under consideration which can be rotated to the right.

  or to the left, in motorized mode, while nevertheless authorizing

  less good adequate delivery of the cleaning or

  similar like, poured from top to bottom on the disc, to the underside of this disc which is furnished with

  cleaning, for example of bristles, or even brushes

naked rotating on the disc.

  To achieve this object, the invention proposes that the wall zones be constituted by directed members

  radially, which cross centrally the perforation considered

  and are nested in it, or are close to

said perforation.

  This effect has the effect of ensuring that the liquid

  cleaner or similar liquid can drain off, respectively

  in the direction of the perforations regardless of the direction of travel

  disc ration; and that the members, directed radially,

  almost give rise to an accumulation or

  similar, occupying respectively a posterior position

  re in the direction of rotation, and by which the liquid or substan-

  this similar is prevented from crossing the perforation without

penetrate this perforation.

  To further improve the desired guidance of the

  liquid, it is also proposed that the inter-

  ception of liquid is symmetrically enlarged in the vicinity of

  each of the perforations, and completely covers said perforation

  drilling with axial spacing; and that an additional collar

  mental, attached to the edge of said inter-flange

  ception which is turned away from the accumulation ring,

  only in the areas directly adjacent to the perforation

  tion considered, extends in the axial direction relative to the fa-

  this posterior of the disc, and be applied against it.

  This additional flange extends approximately-

  ment over a radial length which corresponds substantially to three times the diameter of the perforation, and this in both directions of rotation. This flange makes it possible not only to obtain that the liquid has accumulated on the member and is directed towards

  the corresponding perforation, during the rotation of the dis-

  that, but also that a flow of liquid is prevented both outwards in the radial direction, via the accumulation ring, and inwards in the radial direction, via the flange additional;

  in this way, the liquid can flow properly into the perfo-

  corresponding ration, and it is constrained to this movement of penetration insofar as the corresponding disc is animated

motorized rotation.

  Preferably, it is then expected that the liquid interception flange present, in the region of each

  perforation, a substantially wavy enlargement in the som-

  met (ripple crest) of which the radial member considered

is arranged.

  This embodiment results in enlarging the accumulation space between the accumulation ring, the flange

  interception of liquid, the frame and the additional flange

  mentally, in the region of the perforation, so that the li-

  quide or similar substance, flowing in this region, can penetrate into this region with a sufficient magnitude, and can flow into the perforation. Restraint of flow,

  at the beginning of this region, is reduced thanks to this realization

station.

  To further exert a positive influence on the con-

  flow conditions, it is further provided that the accumulator ring

  mulation merges into the radial member via

of a radial part.

  Thanks to this flow-friendly arrangement, the mem-

  radial scarring may also include, in the inter-

  section between this member and the radial part, marking the transition between the accumulation ring and said member, a substantially triangular bulge which is crossed by a

  axial channel intended to receive fixing means.

  One can for example provide, as means of fi

  fixing, screws with which the unitary assembly

  complete, including the accumulation ring, the

  liquid collection, frame and additional flange

  shut up, can be secured to the back of the disc. This

  structural arrangement provides sufficient material

  material for the establishment and blocking of fastening means in the triangular bulges of the members. This allows,

  moreover, to dispense with the installation of security means

  fixing in a clamping zone, or similar zone, which should

be additionally provided.

  The invention will now be described in more detail, by way of non-limiting example, with reference to the accompanying drawings in which: FIG. 1 is a plan view of an arrangement in accordance with the invention; Figure 2 is a corresponding illustration, in median section; and Figures 3 to 5 show, respectively by a view in

  plan, a median section and a view from below, the means of-

aimed at guiding the liquid.

  The drawings show a disc 1 for a

  floor cleaning, fitted with cleaning devices 2 and for

  before being driven by a motorized rotation. Such floor cleaning machines usually include a tank for cleaning liquid and / or water, as well as a conduit

  tubular which starts from the reservoir, is directed towards the posterior

  of the disc 1 and ends, at a distance in front of this rear face, in the central region or in an eccentrically offset region. The corresponding liquid is poured over this region of the rear face of the disc 1. Said region is then between a median axis 3 of the disc 1, and a line

  circumferential on which are arranged several perfo-

  rations 4 passing through said disc. An accumulation ring 5, arranged above the disc 1, surrounds the perforations 4 while occupying a radially outer position relative to the median axis 3 of the disc. On its marginal edge turned opposite the rear face of the disc, the ring 5 has a circumferential collar 6 for intercepting liquid,

  oriented essentially radially with respect to the axis of the

  dian 3 of the disc 1. Said ring 5 also includes

  wall areas projecting towards the perforations 4 of the

  than 1, which can preferably be nested in these per-

  holes, respectively arranged in the vicinity of a perfo-

  ration 4, and forming an accumulation rim.

  In the embodiment, the net-

  toyage 2 are formed by five brushes rotatably mounted on the disc 1. This disc 1 is rotated around the axis 3 by

  through a motorized drive means, a rota-

  automatic tion then being printed on said devices 2,

by contact with the ground.

  According to the invention, the wall zones engage

  giant in the perforations are constituted by frames

  7 directed radially, which cross centrally the perfora-

  tion 4 considered, in the radial direction, and are nested in

the latter.

  The collar 6 for intercepting liquid is enlarged

  symmetrically in the vicinity of each perforation 4, the widening

  sliding extending, observed in the radial direction, sensitive-

  lying on a region corresponding to three times the diameter of the ladi-

  the perforation 4. This enlargement covers the perforation completely 4. An additional flange 8, attached to the edge of the flange 6 which is turned opposite to the ring

  accumulation 5, only in directly adjacent areas

  nes of the perforation 4 considered, protrudes in the axial direction relative to the rear face of the disc, and is applied against the latter. The interception collar 6 then has, in the region of each perforation 4, a widening of the wavy type in the apex (ripple crest) from which the

  radial member 7 considered is arranged. As put in particular-

  as shown in Figure 5, the accumulation ring 5 merges

  in the radial member 7 via a ra-

  dial 9. In the zone of intersection between the radial member 7 and the radial part 9, marking the transition between the ring 5 and said member 7, this member comprises a substantially triangular bulge 10 which is crossed by an axial channel

  11 intended to receive a fixing screw.

  The disc according to the invention can be selective-

  ment rotated to the right or to the left, a re-

  partition and a corresponding delivery of the liquid takes place

  rant, towards the perforations 4, independently of the direction of rotation

  tion. The liquid poured into the central region of the disc 1 is projected radially outwards, following the rotation of this

  disc 1, it is intercepted by the accumulation ring 5 (col-

  interception ring 6), then is force-guided in the region

  of the perforation 4, under the action of the additional collars

  8 and member 7, so that said liquid can

  flow adequately into the perforation 4. The liquid, coming out of the perforation 4 downwards, spreads on the ground or place

  similar to be cleaned, which is treated by the disposi-

cleaning agents 2.

  All individual and combined features

  of new type, exposed in the description and / or emerging

  designs, are considered to be of an

essential wind.

  The invention is not limited to the embodiment example

  commented on, but can however undergo many modifications.

  in the context of this memo.
