Interchangeable scrub brush or scrub pad for a floor maintenance vehicle

Embodiments include a cleaning head assembly for a floor surface maintenance machine. The cleaning head assembly can include a hub (or cleaning head housing) and a pad or a brush driver, wherein the driver attaches to and aligns axially with the hub (or cleaning head housing) in a touch-free manner.

Cleaning head assemblies having touch-free attachment and alignment technology

Embodiments include a cleaning head assembly for a floor surface maintenance machine. The cleaning head assembly can include a hub (or cleaning head housing) and a pad driver, wherein the pad driver attaches to and aligns axially with the hub (or cleaning head housing) in a touch-free manner.

Embodiments include a mechanism for leveling or providing pad assistance to surface maintenance machines. The surface maintenance machine can include a frame, a plurality of wheels, a head assembly, and a head adjustment mechanism. The head adjustment mechanism can be positioned in line with and operatively coupled to a first portion of the head assembly, such that the first portion of the head assembly can be moved towards or away from the surface by adjusting the position of a fastener in a slot. Such embodiments are useful for leveling the head assembly to maintain an even degree of burnishing or providing pad assistance. Embodiments include methods of using such mechanisms for leveling or providing pad assist to surface maintenance machines.

Surface maintenance machine with a head adjustment mechanism

A flight control apparatus (10, 210, 310 or 410) for use in a model airplane (50, 250, 350 or 450) is described. The apparatus includes a weight (20, 220, 320 or 420) and a resilient band (24, 224, 324 or 424). In the first three embodiments, the weight is mounted in a housing (12, 212 or 312) with the resilient band connected between the weight and the housing. In the fourth embodiment, the weight is mounted on the fuselage (452) of the airplane. The airplane is launched using a standard slingshot-like launching device (56). The resilient member (56A) is mounted around the extension (22, 222 or 422) of the weight in the first, second and fourth embodiments. In the third embodiment, the resilient member is mounted around a hook (354) on the head (350A) of the airplane. To launch, the user (100) holds the tail (60) of the airplane and pulls forward on the post (56B) of the launching device which pulls the weight of the apparatus to the forward most position. The user releases the tail of the airplane and the airplane is launched into the air. Once the airplane reaches its maximum acceleration and begins to decrease in speed, the force of inertia of the weight decreases. When the force of inertia tending to hold the weight forward becomes less than the force of the resilient band, the weight is moved backward.
