Definitions

  • the attachment includes a U-shaped racket which clips to the vacuum cleaner nozzle so that a shaft pivotally connected to the bracket extends across the forward end of the nozzle and is substantially normal to the directions of movement of the nozzle along the rug.
  • a plurality of laterally spaced, arcuate tines project outwardly and downwardly from I the-shaft and then inwardly toward the nozzle.
  • a releasable lock is provided to lock the shaft in any one of a plurality of positions so that, as to at least some of those positions, the tine ends extend beyond the plane of the bottom of the cleaner nozzle when the bottom of the cleaner nozzle is off the rug.
  • the tines When the cleaner nozzle is applied to the rug, the tines are flexed so that tangents at tine-rug contact locations define acute angles with the rug and the measure of the angles is inversely related to the extent of tine extension beyond the plane. Increased flexure of the tines provides more rigid tines and increases the hooked configuration of the tines tomore effectively comb deep pile shag rugs.
  • the shag rug be raked prior to cleaning to separate the shag strands so that the cleaner may pick up dirt between those-strands. After vacuuming, the rug must be raked again to fluff the shag strands and to eliminate the matted strand areas.
  • thetines are sloped rearwardly toward the cleaner so that the tine ends may tend to ride over rather than lift the matted strands, particularly if the rug is a deep pile shag rug and the downward pressure exerted by the tines is not sufficiently great.
  • a shag rug rake attachment for a vacuum cleaner nozzle comprises a U- shaped bracket having legs which clip to the sides of the cleaner nozzle so that the base of the U-shaped bracket extends across the front of the nozzle.
  • a shaft is pivotally connected to the bracket so that it extends across the frontof the nozzle and is substantially normal to the directions of movement of the nozzle along the rug.
  • the attachment further includes a plurality of laterally spaced, arcuate tines which project outwardly and downwardly from the shaft and then inwardly toward the nozzle.
  • the shaft is adjustable to any one of a plurality of positions so that the inwardly projecting tine ends are biased against the rug with a force proportional to the depth of rug pile. Additional adjustment of the tines may be provided if the shag rug rake is associated with a vacuum cleaner having a height adjust ment for the front wheels of the cleaner, and therefore the nozzle. The tines are thereby flexed, a predeten inoperative.
  • the rake 12 comprises a U-shaped bracket 16 mined amount to stiffen the tines and to provide a greater degree of inward hooking so that the shag strands may be picked up and aligned upon the. rearward stroke of the cleaning nozzle.
  • FIG. 1 is a perspective view showing the rug cleaning nozzle with a shag rug rake attached thereto, embodying the principlesof this invention
  • FIG. 2 is a fragmentary plan view of the assembly shown in FIG. 1;
  • FIG. 3 is a fragmentary cross sectional view
  • FIG. 4 is a side elevational view of the assembly shown in FIG. 1 illustrating the tines in a flexed and unflexed condition;
  • FIG. 5 is an exploded view of the shaft adjusting assembly according to this invention. DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawings, and particularly, to FIG;1, a shag rug rake assembly is illustrated.
  • assembly 10 includes a vacuum cleaner nozzle 11 and formed from a single stamping by bending the stamping at areas 17 and 18 to provide attaching vlegs'19 and and a connecting brace member 21.
  • the legs 19 and 20 are initially bent so thatthey extend slightly inwardly and are, thereby, spring biased against the sides 14 and- 1'5 of the cleaner.
  • the legs 19 and 20 are provided with inwardly projecting tabs 22.
  • the tabs 22 are received in pockets23 ,in the nozzle, which are defined by hat-shaped eyeletsor'sockets press-fitted into nozzle openings 24.
  • the sockets or eyelets prevent air leakage into the nozzle when the assembly is removed from the-nozzle.
  • the stiffness of the legs 19 and 20 may be increased by providing stiffening ribs 25 therealong.
  • a square cross shaft 26 which extends across the front of the nozzle between the legs 19 and 20.
  • Apertures 30 provided in the legs 19 and 20 receive the ends of the square shaft 26 so that the shaft may pivot therein.
  • Each projecting end of the shaft isfixed to an adjusting lever 31 by being received within a square aperture 32 provided therein and by a screw 33 which clamps the lever between its head and the associated leg.
  • the head of the screw may be covered by a soft plastic cap 34.
  • Each tine may be molded from a suitable plastic having a plastic memory permitting each tine to be flexed and to spring-back to a normal unflexed 0nd i l h gh h in s-are flexible, they' ri v 3 idly connected at one end to the shaft 26 by hub portions 36 having square bores 37 therethrough.
  • the hub portions also provide the desired lateral spacing of the tines and prevent side-to-side shifting, since all of the hubs are sandwiched between the legs 19 and 20.
  • the levers 31 are fixed to the rotatable shaft 26 and since the tines are rigidly associated at one end with the shaft 26, the position of the tines relative to the nozzle may be adjusted by flexing the levers 31 outwardly until a detent 40 on each lever 31 clears a plurality of notches 41 on each leg 19 and 20. When a desired pivoted position is selected the levers 31 are released to lock the shaft 26 and, therefore, the tines 35 in any one of a plurality of positions.
  • the tine ends extend beyond the plane of the bottom of the cleaner nozzle.
  • the tine is flexed to the condition illustrated in solid outline in FIG. 4. It may be noted that in this position, the tines are flexed so that tangents T at tine-rug contact locations define an acute angle a with the rug. At more forward locations smaller tangent angles are defined so that the measure of the angle a is inversely related to the extent of tine extension beyond the plane of the bottom of the cleaner nozzle and the bottom of the nozzle is off the rug.
  • This adjusting feature has at least two beneficial effects. Firstly, since the more forward adjustment posi tions are intended for combing progressively deeper pile shag rugs, the tines will be more drastically flexed at those adjusted positions to thereby stiffen the tines and make them more suitable for increasingly difficult combing operations. Secondly, by decreasing the angle a, the tines are able to dig through randomly oriented shag strands downwardly to the carpet base and maintain engagement with that base so that the shag strands may be uniformly oriented by the resulting hooked combing action.
  • a shag rug rake attachment for a vacuum cleaner nozzle comprising:
  • bracketmeans adapted to be connected to the forward end of the nozzle; b. shaft means pivotally connected to said bracket means at each end and being substantially normal to the directions of movement of the nozzle along the rug; 3 c. a plurality of laterally spaced, arcuate tines projecting outwardly and downwardly from said shaft and then inwardly toward said nozzle; and d.
  • said shaft means in any one of a plurality of positions, at least including a range of positions which locate unflexed tine ends progressively beyond the plane of the bottom of the cleaner nozzle when the bottom of the nozzle is off the rug; whereby, when the cleaner nozzle is applied to the rug, the tines are flexed so that tangents at tine-rug contact locations define acute angles with the rug and the measure of said angles is inversely related to the extent of tine extension beyond said plane.
  • a shag rug rake attachment according to claim 1 wherein said means to lock said shaft means includes a lever arm having one end fixed to said shaft means and another end releasably engageable with a plurality of notches on said bracket means.
  • a shag rug rake and cleaner comprising:
  • bracket means connected to the forward end of the nozzle
  • shaft means pivotally connected to said bracket means at each end and being substantially normal to the directions of movement of the nozzle along the 'rug;
  • e. means to lock said shaft means in any one of a plurality of positions, at least including a range of positions which locate unflexed tine ends progressively beyond the plane of the bottom of the cleaner noz-- plane.
