Definitions

  • This invention relates to a sweeping device for sweeping surfaces such as floors, glass, vehicles and other surfaces.
  • a sweeping surface is intended to mean a surface that is to be swept.
  • Sweeping devices in the form of squeegees for sweeping up liquids and small particulate matter are known as are devices having bristles for sweeping up larger debris and particulate matter.
  • the latter may have bristles of varying thicknesses to permit a greater range of particles to be swept up.
  • Sweeping devices incorporating both bristles and a squeegee are known. Such devices are arranged such that the squeegee portion and the bristled portion have to be used separately.
  • both a bristled sweeping device as well as a squeegee are required to be used on a sweeping surface. Therefore, at least two passes over a sweeping surface are required, firstly by a bristled sweeping device and then by a squeegee. This results in double the labour requirement than if merely one pass was made over the sweeping surface.
  • a sweeping device comprises an elongated head having operatively upper and lower surfaces, bristles projecting from the lower surface, and at least one elongated blade extending at least partially along the length of the head to project from the lower surface and from a position such that there are bristles on each side thereof.
  • the depth of the blade prefferably be substantially the same as that of the bristles and for the depth of the blade to be substantially parallel to that of the bristles.
  • the head is further provided for the head to be generally rectangular when viewed from the plan view, alternatively for the head to be generally diamond-shaped when viewed in the plan view.
  • the bristles are of varying thicknesses, for the bristles to be of similar length, for the bristles to cover a substantial area of the lower surface of the head, for the bristles to be of sufficient thickness and rigidity for the sweeping device to be used as a rake, alternatively for the bristles to be of sufficient thickness and rigidity for the sweeping device to be used as a broom, for the bristles to be a fibrous material, for the bristles to be of an elastomeric material, for the bristles to be of rubber.
  • the bristles prefferably be arranged in rows extending parallel to the elongate axis of the head, for each row to contain bristles of the same order of thickness, and for there to be alternating rows of thick bristles and thin bristles, alternatively for the bristles to all be of a similar order.
  • the bristles prefferably be substantially cylindrically, alternatively for the bristles to be frusto-conically shaped, having a circular cross-section, where the bristles are preferably tapered in a direction away from the head, and for the bristles to be chamfered at the end.
  • the blade prefferably has a length substantially of the same order as the elongate length of the head, for the blade to be positioned generally centrally extending generally longitudinally with respect to the head, alternatively for the blade to run longitudinally;
  • the head prefferably has a socket in the upper surface for attaching the head to a broom handle, for the socket to have a flexible retaining means on its inner surface for counteracting the removal of the broom handle from the socket, for the retaining means to contain at least one substantially frusto-conically shaped ring tapering towards the base of the socket adapted to exercise a suction grip on the end of a broom handle inserted into the socket when an attempt is make to remove the broom handle from the socket for the retaining means to comprise at least two substantially frusto-conically shaped rings tapering towards the base of the socket.
  • the head, bristles, elastomeric blade and socket prefferably in the form of an integral moulding of a polymeric material.
  • a further feature of the invention is where the head contains a stiffening member, for the stiffening member to be embedded in the head extending along the elongate length of the head, alternatively for the stiffening member to be affixed to the head, for the stiffening member to have a high strength to weight ratio, where the stiffening head to be constructed of a material selected from the group comprising spring steel, mild steel, a polymeric material, polyethylene, polypropylene, plastics materials, fibrous materials, glass fibre, asbestos, synthetic fibrous materials, and mixtures of materials of this group.
  • a further feature of the invention is for the head to have a longitudinally extending transversely projecting blade which is generally transverse with respect to the bristles, for the transversely projecting blade to be configured such that it can be used as a squeegee, for the transversely projecting blade to be integrally moulded with the head, for the transversely projecting blade to have angled corners at its free corners.
  • a sweeping device (1) has an elongate head (2) which is diamond-shaped when viewed from the plan view.
  • the head (2) has an upper surface (3) and a lower surface (4).
  • Bristles (5) project from the lower surface (4).
  • An elastomeric blade (6) projects from the middle of the head (2) in the same direction as the bristles (5) to the same depth as the bristles (5).
  • the bristles (5) are frusto-conically shaped, tapered towards their free ends.
  • the bristles are also chamfered at their free ends to give a generally flat end. There are a sufficient number of bristles (5) to cover most of the lower surface (4) of the head (2).
  • the blade (6) is situated in the middle of the head (2) extending parallel to the longitudinal axis of the head (2) such that it has a length of the same order as the longitudinal axis of the head (2).
  • the blade (6) is surrounded by bristles (5).
  • the head (2) has a socket (7) in its upper surface (3).
  • Two frusto-conically shaped rings (8,9) taper inwards towards the base (10) of the socket (7).
  • a stiffening member (11) composed of a mild steel plate conforms to the general shape of the head (2) when viewed in plan view and is embedded in the head (2).
  • a longitudinally extending transversely projecting blade (12) projects laterally from a lateral face of the head (2).
  • An edge is formed on its free edge making it suitable for use as a squeegee. It has angled corners at its free corners.
  • the sweeping device (1) is manufactured as a unit from a rubber material, thereby permitting the manufacturing of the head (2), the bristles (5), the blade (6), the socket (7) and the longitudinally extending transversely projecting blade (12) in a single manufacturing operation.
  • the sweeping device (1) is made from a rubber which is vulcanised in an injection moulding process, the stiffening member (11) being inserted into the mould in the appropriate position before injection of the rubber and including a coating adapted to promote adhesion between the stiffening member (11) and the rubber material.
  • the socket (7) receives the end of a broom handle (not shown).
  • the frusto-conically shaped rings (8,9) grip the broom handle to resist withdrawal.
  • the broom handle is used to operate the sweeping device such that the bristles (5) and blade (6) are in contact with a sweeping surface (not shown).
  • the sweeping device (1) is functionally operable by moving the device in forward direction (13) or a backward direction (14) against the sweeping surface. Particulate matter (not shown) on the sweeping surface is contacted by the bristles (5). If the particulate matter is too small to be effectively captured by the bristles (5) then the blade (6) captures the particulate matter. In this manner, almost all types of particulate matter can be shifted by the sweeping device (1) across the sweeping surface. Liquids will be captured by the blade and likewise shifted across the sweeping surface by the sweeping device (1). The use of the sweeping device (1) in this fashion permits it to function both a broom and as a squeegee in a single sweeping operation.
  • the sweeping device (1) is reoriented with respect to the sweeping surface such that the longitudinally extending transversely projecting blade (12) contacts the sweeping surface. In this orientation, the bristles (5) and blade (6) are not in contact with the sweeping surface and the device becomes useable as a squeegee.
  • the sweeping device (1) can be replaced without having to replace the broom handle.
  • the broom handle is removed from the socket (7) and placed into the socket of a new sweeping device (1).
  • the sweeping device (1) and broom handle can be made as an integral unit, the sweeping device (1) can be manufactured from sub-components which are later assembled, the bristles can be configured in a pattern of rows where the bristles have varying sizes and the longitudinally extending transversely projecting blade (12) can be omitted from the sweeping device (1).
