Definitions

  • the present invention relates to the field of household tools and, in general, of cleaning tools. More in particular, the present invention relates to a new type of broom or brush.
  • the object of the invention is to provide a broom or a brush having a better efficiency especially for cleaning the areas around the legs of pieces of furniture.
  • a broom, a brush or other cleaning tool comprising a frame, with or without a connecting member for the connection to a handle, and a plurality of bristles anchored to said frame, characterized in that the bristles are subdivided into two groups of bristles, between which a frame portion without bristles is arranged.
  • the tool can comprise a frame and a plurality of bristles anchored to the frame; these bristles are grouped in bundles, fixed in seats obtained on a lower surface of the frame, and are subdivided into two groups of bundles, between which a portion without bristles of the lower surface of the frame is arranged.
  • the bristle bundles are arranged converging and preferably the bundles of the two groups, adjacent to the area without bristles, have distal ends close to one another, preferably into reciprocal contact, and if necessary partially intersecting.
  • two bristle groups When two bristle groups converge, at least in the intermediate area of the tool, they can form a hollow space, i.e. a space without bristles.
  • This space without bristles may be closed at one side by the broom frame and, at the other side, by the bristles that, divided into two groups, converge towards one another.
  • the two bristle groups may converge until interfering with one another.
  • the bristles may be arranged so as to define an area where bristles of the two groups interfere with one another. In this interference area, if present, the ends of some bristles of one bristle group are inserted between the ends of some bristles of the other group.
  • the bristles may be arranged so that the two bristle groups do not interfere with each other, i.e. so that the two groups are spaced from each other, even if preferably converging.
  • the two groups of bristles can interfere with each other only in use, due to the bristle deformation, whilst, when not in use, they are spaced from each other.
  • the tool may be provided with a handle or a handgrip.
  • the handle or handgrip can be produced in a single piece with the frame, or they can be formed by a separate component that can be (reversibly or irreversibly) fixed to the frame.
  • the two bristle groups are arranged substantially like a fan, with a variation in the bristle angle with respect to the tool median plane.
  • the two bristle groups of the cleaning tool are symmetrical to each other.
  • cleaning tools such as brooms or brushes
  • a different asymmetric arrangement of the bristle groups for instance with one bristle group larger than the other one.
  • the invention will be described below with particular reference to a broom. However, it should be understood that the invention can also be applied to other cleaning tools, such as for instance a brush.
  • the tool is provided with a frame, stick or lath, to which bristles are anchored forming the actual cleaning member.
  • the drawing shows a particularly advantageous embodiment of the invention.
  • the broom indicated as a whole with number 1, is usually provided with a handle 3, shown only in figures 6 and 7 and omitted in the remaining figures 1-5 .
  • the broom 1 comprises a frame, stick or lath 5 equipped with a sleeve 7, preferably in a central position, forming a connecting member for connecting the brush to the handle.
  • the sleeve 7 may be threaded inside or differently shaped to form a preferably reversible connecting system for connecting the handle 3.
  • the connecting member may be positioned in a non-central position and the frame may be asymmetric.
  • the frame or stick 5 of the broom 1 is manufactured integrally as a single piece with the sleeve 7, made for instance of molded plastic.
  • Bristles are anchored in the lower part of the frame or stick 5 and form the cleaning element, i.e. the element with which the broom 1 is equipped for collecting dirt.
  • the bristles may be of any adequate material and have adequate length.
  • the bristles 9 are characteristically divided into two bristle groups, indicated respectively with 9A and 9B.
  • the frame 5 has, in the intermediate area between the two bristle groups 9A, 9B, an area 5A without bristles.
  • the bristle groups 9A, 9B are substantially symmetric with respect to a median plane of the broom corresponding to the trace of the cross section line III-III of figure 2 .
  • the area 5A without bristles of the frame 5 is in correspondence of the sleeve 7 forming the connecting member for the handle 3.
  • the bristles may be arranged asymmetrically, for instance a bristle group may have greater extension than the other one.
  • the bristles of the two groups are arranged in a substantially fan-like manner. These two bristle fans intersect in the central area.
  • This arrangement is currently preferred, although not essential; for instance, arrangements may be provided wherein the bristles of the two groups touch one another in the area of maximum approach, without intersecting, or arrangements wherein the bristles of the two groups do not touch one another, or arrangements wherein they touch, and interfere with, one another only when the broom is stressed, with the bristles bent against the surface to be cleaned, with consequent enlargement of the two bristle fans.
  • it is in general preferable that the bristles of the two groups converge in the central area.
  • the bristles 9 are grouped in bundles 9F that are anchored in suitable seats formed on the lower surface of the stick or frame 5.
  • the inclination of the bristles, and in particular of the bristle bundles 9F, is preferably variable along the transverse extension of the frame or stick 5.
  • the variability of the angle of inclination of the bristle bundles 9F is shown in particular in figure 2 .
  • the bristle bundles 9F have an inclination, with respect to the vertical, gradually varying from an angle ⁇ 1 to an angle ⁇ 2 of opposite sign. With such a configuration, the bristles of the group 9A converge towards the bristles of the group 9B in the central area of the broom 1.
  • a central hollow space, indicated with V is defined of nearly triangular shape; the bristles of the groups 9A and 9B are arranged on both sides of this space V.
  • This volume V of substantially triangular cross section, has the vertex in correspondence of the intersection area of central bundles 9F.
  • the bristle bundles 9F have a substantially conical conformation, as the bristles tend to enlarge from the proximal end (the one fixed to the frame or stick 5) towards the distal end (the one farthest from the frame or stick 5), and therefore the angle (variable from ⁇ 1 to ⁇ 2 ) formed between bristle bundles and median plane can be referred to the axis of the bundles 9F.
  • the lower surface 5S of the stick or frame 5 of the broom 1 has preferably a curvilinear shape.
  • the curvature of the lower surface 5S of the frame or stick 5 is such that the bristle bundles 9F are always nearly orthogonal to the surface 5S in the point where the bristles are anchored onto the stick or frame 5 of the broom.
  • these latter may actually have a conical shape, as schematically shown in the drawing.
  • the abovementioned orthogonality is referred to the axis of the cone formed by the bristles of each bundle 9F.
  • the bristle anchoring surface of the frame has advantageously two surface portions, onto which the two bristle groups 9A and 9B are respectively anchored, which have a convex profile and between which the surface portion or area 5A without bristles is defined. Thanks to the convexity of the bristle anchoring surfaces, the two bristle groups can be arranged according to two fans, wherein the bristles are substantially orthogonal to the anchoring surface formed by the frame 5.
  • the broom frame or stick 5 forms two arched areas, preferably substantially symmetrical with respect to the central plane corresponding to the plane of section III-III of figure 2 .
  • the two arched portions of frame 5 define the lower arched surface indicated as a whole with 5S, onto which the bristle bundles 9F are anchored.
  • the two arched portions extend from a central core of the frame 5, in correspondence of which the sleeve 7 is provided, towards the opposite distal ends of the frame 5.
  • the broom frame may be provided, in some embodiments, with bracings 5V.
  • These bracings 5V are preferably arched.
  • each bracing 5V extends from the central sleeve 7 towards the corresponding distal end of the frame or stick 5.
  • Each bracing 5V has preferably a curvilinear profile with extrados facing the broom handle and intrados facing the bristles 9, i.e. the bracings 5V are shaped with a curvature opposite to that of the portions of the frame 5 defining the curved surfaces 5S for anchoring the bundles of bristles 9.
  • the bracings may be designed also differently, for instance with a rectilinear profile inclined with respect to the broom median plane.
  • the bracings may be formed by joined rectilinear portions extending preferably from the central area, where the sleeve is located, towards the distal ends of the frame 5.
  • the bracings may be shorter, extending for instance only until the half, or two thirds, of the extension of the frame from the sleeve 7 to the end.
  • Such a broom allows to obtain particular advantages in use, that are clearly apparent from figures 6 and 7 , where the use of the broom for cleaning areas around legs G of a table T is shown.
  • the particular arrangements of the bristles 9 in two groups 9A, 9B, with a hollow area V between them, allows the user to arrange the broom around the leg G, so that the bristles surround the leg. With rotating movements around the leg and movements away from the leg, according to the direction indicated by the arrow f, it is therefore possible effectively to remove the dirt accumulated around the legs G.
  • the best effectiveness of the broom is obtained by arranging the two bristle groups 9A, 9B so as to obtain an interference between the bundles 9F nearest the center plane; it is however also possible to provide the area or hollow space V with a slightly different shape, for instance also without the interference of the most internal bristles, as shown in the preferred embodiment of the attached figures.
