  • Floor scrubbers and other apparatus for treating a floor surface typically include a head assembly in which one or more brushes, pads or other floor surface treatment devices are configured for engagement with the floor surface and are rotatably driven relative to the floor surface to scrub, polish or otherwise treat the floor surface as desired.
  • the head assembly of a conventional floor scrubber typically includes one, or in a dual scrubbing machine two, circular or ring-shaped brush plates each having a depending bristle brush adapted for engagement with the floor surface.
  • the brush plate is operatively connected to a drive motor for rotation of the brush plate relative to the floor surface to scrub the floor surface.
  • the drive motor has a drive shaft corresponding to each brush plate and terminating in a three lug configuration.
  • Each brush plate has notches, or grooves, corresponding to the lugs of the drive shaft for releasably connecting the brush head to the drive shaft.
  • the releasable connection allows for replacement of the brush head in the event the bristles become worn or a different floor treatment is desired.
  • removing and replacing the brush head is often cumbersome and frustrating for the operator because the operator must either lay down on the floor to see underneath the machine or blindly reach under the machine to manipulate the brush head relative to the lugs of the drive shaft. It is therefore difficult for the operator to properly align the notches or grooves of the brush plate with the lugs of the drive shaft, often requiring the operator to rotate the entire head assembly relative to the shaft up to 60° to connect the brush head to the drive shaft.

Abstract

Cette invention concerne un appareil de traitement pour surfaces de plancher équipé d'un moteur d'entraînement qui fait tourner un arbre menant sur son axe de rotation, et un ensemble menant solidaire de l'arbre menant avec lequel il tourne. Ce dispositif de traitement pour surfaces de plancher est relié libérable à l'ensemble menant avec lequel il tourne conjointement sur l'axe de rotation de l'arbre menant. Le dispositif de traitement pour surfaces de plancher est conçu pour entrer en contact avec la surface de plancher qu'il traite par effet de rotation. Dans un mode de réalisation préféré, l'ensemble menant comporte un ensemble de dents de pignon et le dispositif de traitement pour surfaces de plancher un ensemble de dents de pignon correspondant, le dispositif de traitement pour surfaces de plancher étant dimensionné par rapport à l'ensemble menant de telle sorte que ses dents de pignon engrènent, en les entraînant, sur les dents de pignon du dispositif de traitement pour surfaces de plancher.
