Definitions

  • the invention provides improved means for securing the fabric to the base of the brush, improved means for rotatably mounting the base of the brush on the brush body whereby the brush base can be turned by manipulations above the brush body, and means for indicating from above the body of the brush the position of the brush base relative thereto.
  • This invention relates to a brush having a body and a bristle-carrying base rotatable thereon.
  • the bristlecarrying base is directional in its operation as by having all, or a predominant part of the bristles inclined in the same direction.
  • a brush having a rotatable base held in position by a spiral spring.
  • the brush elements are embedded in a flat, flexible carrier part, such as a fabric or the like, or mounted thereon, and the flat carrier, preferably padded by a flexible material, is inserted in a solid part preferably made of plastic material.
  • the padded brush element is retained by a flat frame on a base plate which is provided with a centrally arranged upwardly extending hollow two-part sleeve which a bolt with a knob 3,619,846 Patented Nov. 16, 1971 engages positively.
  • the upper part of the brush has a bore which is coaxial with the bore in the sleeve into which the head of the bolt slides; the spiral spring is placed around the periphery of the upper sleeve part, with one end abutting the underside of the knob and the other end against a stop connected to the upper part of the brush.
  • FIG. 1 is a view in side elevation of the brush
  • FIG. 1A is a fragmentary view in section on an enlarged scale, of a portion of the brush element per se;
  • FIG. 2 is a fragmentary view in longitudinal section through the brush of FIG. 1 showing a cross-sectional view of the upper sleeve section of the base plate;
  • FIG. 3 is a fragmentary plan view of the rear or spine of the brush.
  • FIG. 4 is a view in transverse section through the second, inner sleeve section which is integral with the base plate of the brush, the section being taken along line 4-4 of FIG. 2.
  • the brush apart from the pad P and the brush element B, consists of four individual parts, which are all so formed that they can be assembled without additional fastening means such as screws, pins or the like. These four parts are preferably made of plastic material and are assembled in a very simple manner.
  • a base plate 1 with a pad P and a brush element B clamped firmly by a frame 13 forms the base of the brush which is rotatable about a center with respect to the upper part 10 and handle 16 of the brush.
  • the brush element B is made up of a fabric 20 (FIG. 1A) which carries a plurality of short bristles 21 inclined in the same direction.
  • the peripheral edge 1 of the base plate 1 is bent upwards and inclined inwardly and provided with teeth at its edge 1a.
  • the edge portion of the brush element B projecting beyond the plastic foam padding P is placed over these teeth, so that it is retained at this point from below.
  • a flat frame 13, about the circumference of which a defining ledge 14 extends substantially vertically to the frame 13 is placed on the upper surface of the base plate 1.
  • the toothed ledge 13a on the underside of the frame plate 13 is so located that, when the frame is mounted, it assumes a position behind the serrated edge 1a on the periphery of the base plate 1.
  • the brush element B is retained firmly in position by oppositely acting rows of serrations 1a and 13a.
  • the frame 13 is retained on the base plate 1 by barbs 15 formed of the material of the surface of this base plate, which barbs engage over the rim edge 13 on the inside circumference of the flat frame plate 13-.
  • the base plate 1 has a central bore 2, an upstanding central sleeve 3, 4, with the lower portion '3 of the sleeve having a greater diameter than portion 4.
  • the height of the sleeve 3, 4 corresponds substantially with the internal height of the brush handle body.
  • the lower section 3 of the sleeve is defined by an inwardly projecting flange 3', which also forms a shoulder from which the second sleeve section 4 proceeds.
  • the bore 2 of the lower sleeve section 3 may be of any desired size and is preferably cylindrical.
  • the bore in the upper section 4 of the sleeve serves to receive and to retain a retaining member in the form of a bolt provided with a knob.
  • FIG. 4 An embodiment particularly convenient for production is shown in FIG. 4 of the drawing.
  • the axial bore provided in the upper sleeve section 4 is square, the edges being chamfered.
  • Level with flange 3', at the transition between the lower and upper sleeve sections 3 and 4, the passage between the bores 2 and 5 is tapered to form the rectangular bore cross-section.
  • the two opposite sides 4 of the square bore are beveled level with flange 3' and terminate in oppositely directed pointed edges 4a, which simultaneously form the long sides of the rectangular passage.
  • a bolt 6 provided with a knob 7 is inserted in this square bore 5 in the upper sleeve section 4.
  • the crosssection of the bolt 6 corresponds to the cross-section of the square bore 5 in the upper sleeve section 4 of the base plate 1.
  • This bolt 6 is provided with a slit 8 extending vertically upwards from the free lower end. This slit 8 imparts resilience to the thus formed bolt sections.
  • the side surfaces of the bolt 6 opposite the slit 8 taper in their lower section and each terminate in a point 6a which is formed like a barb.
  • the upper brush section 110 has a circular bore 12 flush with the bore 2, 5 in the sleeve section 3, 4 the diameter of the bore being somewhat larger than the diameter of the knob 7 of the bolt 6, so that this knob is able to slide in the bore.
  • a cylindrical sleeve 11 From this bore 12 into the interior of the upper brush portion there extends a cylindrical sleeve 11, at the lower end of which is the radially inwardly facing flange 11'.
  • the underside of this flange 11' rests on the upper surface of the shoulder 3' formed by the two sleeve sections 3 and 4 of the base plate 1, whilst the upper surface of this flange 11 carries the lower end of the spiral spring 9.
  • the brush element B On assembly of the brush, the brush element B is first placed with the underlaid plastic foam padding P around the upwardly pointing teeth In on the outer circumference of the base plate 1. Then the frame 13 is placed from above thereon and firmly pressed against the barbs 15 in the base plate 1, so that these barbs snap over the inside edge of the frame plate 13. The teeth 13a are thus firmly pressed on the underside of the frame plate 113 into the edge section of the brush element B. This edge section of the brush element is urged vertically upwards by the peripheral teeth In. of the base plate and vertically downwards by the toothed ledge 13' engaging behind these peripheral teeth. The peripheral teeth 1' thus abut against the underside of the frame plate 13, whilst the toothed ledge 13' abuts against the upper surface of the base plate 1. The unit so assembled forms the rotatable base of the brush.
  • the upper brush part with the bore 12 and the sleeve 11 is slid over the upper sleeve part 4 of the sleeve 3, 4 proceeding from the base plate, and finally the bolt 6 and the spiral spring 9 are inserted, the brush being thus completed.
  • the upper brush part 10 is retained in position by the spring 9 and the shoulder 3 between the sleeve sections 2, 3.
  • the lower edge of the side walls 10' of the upper part 10 engage the upper surface of the flat frame plate 13 which is fast to the base plate 1.
  • the square bolt 6 with barbed tips 6a establishes a positive connection with the base plate 1 supporting the brush element B such that when the base plate 1 is turned, the bolt 6 and the knob 7 are also rotated.
  • the knob 7 is depressed against the force of the spring 9, the frame plate 13 of the base of the brush being thus thrust away from the edge of wall 10' of the upper brush part 10.
  • Base plate 1 may now be turned relative to the upper part 10 of the brush.
  • the spring 9 returns into its original position and pulls the base against the free edge of the side walls '10 of the upper brush part 10, and the knob 7 appears again above the surface of the back of the brush.
  • This knob 7 renders manipulation and operation of the brush extremely simple. Since it rotates with the brush base, a direction arrow 17 arranged on the surface of the knob 7 immediately allows the required direction of brushing to be ascertained.
  • the base outline of the brush is optional, an oval or circular form being preferable.
  • the connection between knob and brush base may be effected in a number of other manners.
  • the embodiment shown and described is preferred for manufacturing reasons. Where parts are, for clarity and convenience, referred to on the basis. of their oriented position shown in the accompanying drawing, no limitation as to positioning of the entire structure is to 'be implied, since it will be understood that the entire structure may be inverted or that it may be used in any inclined position.
  • a brush having a body and a bristle-carrying base plate mounted for selective rotation upon the brush body, the improvement which comprises a centrally disposed bearing means having an axis disposed normal to the broad extent to the base plate for securing the body and base plate together for relative rotation with respect to each other, and means secured to the base plate and operable from above the brush body for selectively rotating the base plate with respect to the body of the brush.
  • a brush according to claim 2 wherein the bristles are mounted upon a flexible sheet, and comprising means securing the edge of the sheet to the periphery of the base plate.
  • a brush according to claim 3 comprising a resilient pad disposed between the base plate and the sheet, said pad maintaining the sheet taut.
