Abstract
A vertical axis brush for use with a rotary floor maintenance apparatus is disclosed. The brush includes a holder plate having an integral peripherally extending and depending skirt to which are detachably secured a plurality of brush segments. Each brush segment is generally U-shaped in plan and is held to the holder plate by a pair of opposed clamps which define a channel. The clamps are integral with the plate and radially receive the brush members in a detachable snap fit fashion. When mounted, each of the brush members is engaged by the clamps and also engaged by the depending skirt of the holder plate.
Claims25
A segmented vertical axis brush for use with a floor treating machine, said brush comprising:
- a brush holder plate having an integral peripherally extending, depending skirt, said plate further having a central, rotary axis;
- a plurality of brush members, each brush member including a base element and a plurality of bristles held by said base element;
- and
- mounting means circumferentially spaced around said central axis and on said brush holder plate and extending downwardly therefrom for radially receiving and detachably yet positively mounting said brush members to said plate in a snap fit fashion, each of said brush members when mounted, engaging an inner peripheral surface of said skirt and extending radially outwardly from said central rotary axis of said brush holder plate whereby said brush members may be mounted and removed from said plate without the use of tools.
A vertical axis floor treating member of the type including a plurality of floor engaging elements, said member comprising:
- a generally circular plate having a central aperture;
- a plurality of floor engaging elements, each of said elements including an elongated strip-like member configured to a generally U-shape in plan thereby having leg portions and a base portion;
- a plurality of retaining means on said plate for radially receiving and detachably retaining in a snap fit fashion each of said floor engaging elements on said plate, said leg portions of each of said strip-like members being engaged by one of said retaining means so that said elements extend radially from said central aperture and are circumferentially spaced around said aperture;
- and
- peripheral means extending around said plate and having a surface engaging and radially retaining said floor engaging elements.
A brush holder for holding a plurality of brush members and which is usable in a rotary floor treating machine, said brush holder comprising:
- a plate having an integral, depending, peripheral skirt and a center axis;
- and
- a plurality of mounting means on said plate for radially receiving and mounting a plurality of floor treating brushes to the plate in cooperation with said skirt and in a detachable, snap fit fashion, each of said mounting means comprising a pair of circumferentially spaced, resilient clamp members extending in opposed relationship from a point spaced radially inwardly from said skirt and towards a center axis of said plate.
A scrub brush adapted to be mounted on a holder plate in a snap fit, detachable fashion, the holder plate having a retainer means for retaining the brush to the plate which includes a pair of opposed resilient clamp members which define a channel for receipt of the brush and wherein the plate further includes a depending, peripheral skirt, said scrub brush comprising:
- an elongated base having a generally U-shape in plan thereby including leg portions joined by a base portion, said leg portions converging towards each other;
- and
- a plurality of bristles held by said base.
