Definitions

  • This invention concerns a household appliance and more particularly a brush.
  • Brushes whose bristles are provided by an integral rubber moulding are known. They are particularly effective for sweeping hair and are widely used in hairdressing salons. They are not in general domestic use, largely because of their high cost. This cost arises mainly from the lengthy production time of upwards of seven minutes per cycle necessary to ensure complete curing of the rubber before removing the brush from the mould. Any attempt at premature removal causes breakage of the bristles. Another factor influencing cost is the provision of a steel reinforcing plate within the portion from which the bristles extend. This must be completely encapsulated to protect it from corrosion and sufficient rubber material must be provided for this purpose. Also it adds considerable weight.
  • a brush comprising a moulding of soft modified thermoplastic reinforced by a portion of hard thermo ⁇ plastic.
  • the portion of hard thermoplastic need not be totally enclosed.
  • thermoplastic materials By using thermoplastic materials, the production time can be reduced to less than one minute.
  • Figure 1 shows an end view of the brush
  • Figure 2 shows a front view of the brush
  • Figure 3 shows a top view of the brush
  • Figure 4 shows a cross-section through the brush on the line IV-IV of Figure 2.
  • the brush comprises a reinforcement member 10 moulded from a hard thermoplastics material, and an integral moulding 11 of a soft modified thermoplastics material.
  • the moulding 11 comprises a multiplicity of bristles 12 spaced from one another and arranged in columns 13 and rows 14 all depending from a sheet-like portion 15 extending over the lower surface of the member 10.
  • the edges 16 of the portion 15 turn upwardly and inwardly to wrap over the perimeter edge of the member 10.
  • the molding 11 also includes a central portion 17 extending upwardly from the portion 15 through an aperture 18 in the member 10.
  • the portion 17 defines a socket 19 for receipt of -a broom handle 20 indicated in chain-dotted lines.
  • the moulding 11 also provides a "squeegee" blade 21.
  • the brush is manufactured by first producing the member 10 in an injection moulding machine.
  • the member 10 is then positioned within the mould cavity of a further injection moulding machine which forms the moulding 11 on and around the member 10.
  • the " plastics material cools sufficiently to allow the brush to be stripped from the mould without damage in rather less than one minute.
  • the reinforcement member is provided with lugs projecting from its underside and engageable with sockets in that portion of the mould cavity defining the bristles to locate and support the reinforcement member in the mould cavity.
  • the portion 10 and moulding 11 may be of different and attractive colours making the brush appealing for the domestic market.
  • edges 16 surrounding the brush head prevent damage to objects against the head may impact when in use.
  • the brush need not be a broom, it may be a hand brush as used with a dustpan or a clothes brush, for example.
  • reinforcement member and moulding 11 may be formed sequentially in a single composite mould.

Abstract

L'invention concerne une brosse constituée d'un élément de renfort (10) moulé dans une matière thermoplastique dure, et d'un moulage formant une seule pièce (11) molle en matière thermoplastique modifiée. La brosse est fabriquée par un premier moulage par injection de l'élément (10) qui est ensuite placé dans le moule d'une autre presse à injecter qui forme le moulage (11) autour de l'élément (10). La brosse peut également comprendre un manchon (19) de manche à balai ainsi qu'une lame en caoutchouc ou une raclette (21) également moulée en une seule pièce. Les deux moulages peuvent être de couleurs différentes.
