Definitions

  • This invention concerns a scrubbing brush made of extremely resistant plastic materials for sweeping, raking, scraping and levelling flooring of any kind.
  • This invention was designed in order to introduce an exceptionally versatile and efficient tool in the technique used in this sector, and to carry out at the same time, all those operations for which a number of different tools have to date been required.
  • the tool in question consists of a large scrubbing brush made of a resistant mixture of thermoplastic resins and fitted at the bottom with a set of sturdy but elastic blades, arranged in a preset geometric pattern, capable not only of collecting and sweeping away refuse of any type, but also of disintegrating even the most resistant masses of dust, soil or different types of debris.
  • This scrubbing brush is fitted on a supporting plate above which the long handle for maneuvering the tool is fitted by means of a coupling sleeve with various adjustment positions.
  • blades are in fact arranged in two directions, some longitudinally with respect to the major axis of the scrubbing brush and others transversely; regardless of whether the scrubbing brush is used with alternating movements parallel to its longitudinal axis or with alternating movements orthogonal to its longitudinal axis, with this arrangement there are some blades, under the scrubbing brush, which operate flat to collect and sweep the dirt and the other blades which are orthogonal to the previous blades that operate edgewise blades to disintegrate solid dirt masses, like a blade.
  • the blades above all the orthogonally arranged blades, must be suitably spaced so that when a blade is bent towards the adjacent or orthogonal blade as a result of flooring friction, it does not cover the end section of the latter so that the same is not prevented from cutting and consequently removing solidified debris firmly fixed to the flooring.
  • both the blades arranged longitudinally and those arranged transversely with respect to the longitudinal axis of the brush are positioned so as to cover together the full surface on which the scrubbing brush is used in both directions with alternating movements over the space to be cleaned; this arrangement is extremely important since it is this feature which makes it possible for the scrubbing brush in question to clean any surface uniformly without leaving behind even the smallest trace of dirt as often happens in the case of rakes or brooms where small residues wedge between the teeth of a rake or the bristles of a broom.
  • the scrubbing brush in question acts like a scraper in terms of compactness and continuity, with the difference in respect to a standard blade that it can in addition disintegrate and sweep the dirt as the user requires.
  • the invention consists of a brush (1) made of a resistant mixture of thermoplastic resins, fitted under a supporting plate (2) fitted at the top with a mouthpiece (3) in which the handle of the tool is fitted.
  • the brush (1) which is rectangular in shape with a fairly accentuated point at the front, has many blades on the bottom face by means of which the scrubbing brush actually operates on the surface to be cleaned; some (1a) of which are arranged peripherally along the three rectilinear sides of the brush, while others (1b) are arranged inside the surface of the brush parallel with respect to the longitudinal axis of the same, others (1c) are arranged inside the surface of the scrubbing brush in an orthogonal position with respect to this longitudinal axis and yet others (1d) are arranged on the pointed front edge of the scrubbing brush, slightly apart, with respect to the longitudinal median axis of the scrubbing brush.
  • the longitudinal blades and the transverse blades must together cover a continuous surface in two directions under the brush (1) so as to prevent the dirt from penetrating and therefore escaping between the blades; regarding the space between the blades in the middle section, it is worth reiterating that this space is not only constant from one end of the brush (1) to the other but is a function of the height of the blades in that never does a blade bent by the friction with the flooring, abut against the adjacent blade placed orthogonally to it, so as to cover the end section completely, to avoid loosing the cutting action on the dirt which, in the brush according to the invention, is carried out by those blades which operate edgewise.
  • the brush (1) has a tapered front end, allows the user to reach even very narrow corners, while the fact that the blades (1d) are positioned slightly apart makes it not only possible to clean these difficult areas more thoroughly but also to prevent the brush (1) from spreading the dirt swept away with its front end; in fact the arrangement of these front blades (1d) produces an important action, particularly when the brush (1) in question is used with transverse movements, in that it pulls the dust and debris collected in towards the surface of the brush (1) without leaving even the smallest trace of dirt on the flooring.
  • this brush (1) must be connected to a matching supporting plate (2); this coupling can either be fixed and permanent or easily removable to allow a brush which is worn by extended use to be replaced on the supporting plate (2) in question.
  • the brush (1) peripherally on its top face, has a continuous edge segmented at a certain width in which the matching periphery edges of the above plate (2) are fitted.
  • This supporting plate (2) made of moulded plastic material has a matching surface which is however smaller than the brush (1) fitted underneath, the same being fitted with a longitudinal raised profile (2a) extending from the front end for approximately three quarters of its length.
  • a supporting bracket (3a) for a mouthpiece with a circular transverse cross-section (3) produced during moulding together with the supporting plate (2), on which a standard handle for using the brush is fitted, projects from the top edge of this longitudinal profile (2a).
  • the moulding material of the section where the bracket (3a) is fixed transversely to the top face of the plate (2) has a lighter section which acts as a joint or a hinge to allow the mouthpiece (3) and consequently the handle fitted on the same, to be placed in different inclinations with respect to the flat surface of the supporting plate (2).
  • the same is fitted with along front lever (3b), also produced during moulding, which is slightly curved at the front end, and which fits and is fixed by alternating forced movements into one of the hollows of a comb (2b) on the back of the raised profile (2a) of the supporting plate (2).
  • the moulding material has another lighter section in the area in which the above lever (3b) is fixed to the mouthpiece (3), which again acts as a joint or a hinge.
  • the action by the user on the handle of the tool according to the invention is in fact discharged both on the point at which the bracket (3a) of the mouthpiece (3) is fitted to the back of the profile (2a) of the supporting plate (2) and on the insertion point of the lever (3b) of the mouthpiece (3) in the comb (2b); this makes it possible to operate an equiverse and parallel torque on the supporting plate (2), which prevents rotation on the horizontal plane of the brush (1) to make the latter as useful as possible both when it is used longitudinally and when it is used transversely.
  • the comb could be moved directly on the mouthpiece (3), but in this case an end of the lever (3b) would be fixed to the back of the raised profile (2a) of the plate (2); a double comb could even be fitted, one on the profile (2a) of the plate (2) and another on the mouthpiece (3) in which the free ends of a specially designed connection lever could be fitted.
  • any combs possibly realized on the tool according to the invention are realized by an alternation of transverse hollows (C) and transverse raised sections (P) suitably shaped to obtained mushroom shaped transverse cross-sections; these raised sections (P) must be fairly elastic so as to become thinner to allow the end of the lever (3b) to be fitted into the hollow (C) as required, and must then return to their normal size so as to at least partially obstruct the hollow (C) in which the lever which projects from the mouthpiece (3) is fitted, to prevent this lever from escaping accidentally.
  • these transverse raised sections have a longitudinal groove, produced in any way whatsoever, for their complete length to give them the elasticity required.
  • FIG. 5 A top view (fig. 5) and a longitudinal cross-section (fig. 6) of a comb (2b*) are given in figures 5 and 6 - which, instead of being inserted and built-into a special hollow on the back of the supporting plate (2) as in the case of the previous version - is produced in a single moulded piece with the plate (2).
  • transverse raised sections (P*) which separate the transverse hollows (C*) are fitted on one side with a flat and vertical side wall (P1) and on the opposite side with a convex wall (P2) with the convexity turned towards the hollow (C*).
  • Each of the convex walls (P2) is made lighter by a pair of notches (P2*) which extend towards the bottom wall of each hollow (C*) in order to make the convex wall (P2) elastic enough to snap the ends of the lever (3b) into the hollow (C*) as required.
