Abstract: A brush system utilizable with a floor-cleaning machine includes brush head, a coupler, and a riser, wherein the coupler is a flexible coupler for adjusting the position of the riser relative to the brush head. The brush head essentially comprises a bristled pad that may be peeled off a floor machine pad driver.

Abstract: A floor brush for using with floor cleaning equipment and, more specifically, a brush head (1) having distinct zones of varying bristle tuft (41) arrangements and configurations is provided. The brush head (1) is adapted for detachable connecting to a floor maintenance machine which is utilized for cleaning, burnishing, buffing and polishing a work surface such as a floor or the like.

Abstract: A pad driver for use with a floor maintenance machine that includes a riser portion and a driver disc portion that defines a driving surface which is engageable with a floor maintenance pad. The riser includes a radial flange which extends outwardly from a central hub. The radial flange includes a rim portion supported radially outwardly from the hub by a plurality of spoke-like regions. Regions of reduced material thickness separate the spoke-like regions. The hub is generally cup-shaped and includes a planar upper disc portion and a stepped, transition portion that joins the upper disc portion with the radial extending flange. A plurality of radially extending, rigidizing axial ribs extend between the underside of the upper disc portion and the inside of the stepped transition portion. The driver disc portion may comprise a separate driver disc attached to the riser or alternately, comprise a plurality of driving elements molded into the radial flange.

Abstract: A molded pad driver for use with floor maintenance machines including structure that defines a circular disc-like body, the body defining a driving surface that is abuttably engageable with a driven surface of a floor maintenance pad to which it is attached. The driving surface is at least partially defined by a plurality of sets of protrusions with each set of protrusions preferably consisting of a plurality of protruding members arranged in a circular patterns, such that each protruding member of a set is at a slightly different orientation with respect to all of the members of a set, as viewed from a plane parallel to a plane of the pad driver. Each protruding member preferably consists of an arrowhead member including a stanchion that extends axially from a base surface on the pad driver and terminates in an arcuate crossbar that extends generally laterally with respect to the rotational axis of the pad driver.

Abstract: A coupling device adapted for use with floor maintenance machines of the type used for floor brushing, buffing, polishing, scrubbing or the like and which facilitates the coupling of a maintenance element (i.e., brush, buffing disk or the like). The device comprises an annular plate member having a circular opening adapted to receive a circular drive hub carried by the machine drive shaft with the drive shaft having radially projecting lugs that are adapted to pass through radially extending arcuate recesses formed in the plate member so as to lockably engage behind the plate member. On one side of the coupling device, a first series of inner peripheral cam-like ramps communicate with one end of the arcuate recesses and on the opposite of the plate member, a second series of inner peripheral cam-like ramps communicate with the opposite ends of the arcuate recesses.

Abstract: A coupler is disclosed for coupling floor maintenance pads to a driven pad disc. The coupler has one part for mounting on the driven disc and a second part which threads to the first part for holding and centering a maintenance pad to a disc. A lock arrangement is provided for preventing the coupler from becoming unthreaded during operation. The locking arrangement is formed by a detent mechanism. One part of the detent mechanism is formed on the first part and another cooperating part of the detent mechanism is formed on the second part. When the coupler parts are threaded together to secure a pad, the detent mechanism engages and provides a resisting force against unthreading. In another embodiment, wedge-shaped projections are formed on one part of the coupler for engaging a pad and resisting loosening.
