A reversible rotary shampoo machine or floor waxer is provided which consists of a reversible motor and a reversing switch having a safety off position electrically connected in a circuit to the reversible motor, with the reversing switch mechanically interlocked to the on/off switch so that the on/off switch must turn off the motor before the reversing switch is permitted to change the direction of rotation of the reversible motor, in order to prevent damage to the reversible motor, or accidental injury to an operator.
A motorized brush apparatus including a supply of a fluid, such as water, that is selectively actuated upon a targeted surface. A switch allows a user to selectively interrupt the rotational movement applied to a rotating brush assembly at one end of a shaft. A motor assembly is mounted preferably at the other end of the shaft. A source of a fluid is connected to a conduit member that extends along the shaft and ends with an outlet that directs the fluid axially and in parallel with the rotating bristles. The bristles are perpendicularly mounted to a rotating base plate provided with arched openings that allow the fluid to pass through.
A handle for an electric floor polishing or burnishing machine comprising a centrally-mounted actuator with safety lock is disclosed. In one embodiment, the handle is generally T-shaped and has a centrally-mounted actuator, which offers an operator more control over the polisher or burnisher and allows for one-handed operation. In another embodiment, the handle also has a safety lock which prevents the accidental operation of the machine.
A rotary floor machine having a base, a pole handle, a pole structure, a handlebar, a trigger bar, and a lock-out device. The pole handle is pivotally secured to the base and is movable between a vertical position and a rear angular position. The pole structure is secured to the pole handle. The handlebar is secured to the pole structure so as to be substantially perpendicular to the pole handle. The trigger bar controls the starting and stopping of the rotary floor machine and is mounted to the handlebar so as to be movable between proximate and distal positions relative to the handlebar. The trigger bar starts the rotary floor machine when in the proximate position and stops the rotary floor machine when in the distal position. The lock-out device has an element that is movable between a blocking position and an un-blocking position in response to movement of the pole handle between the vertical position and the rear angular position. When the element is in the blocking position, the element blocks the movement of the trigger bar from the distal position to the proximate position. When the element is in the un-blocking position, the element does not block the movement of the trigger bar to the proximate position.
A handle assembly (10) for a floor maintenance machine (12) includes a hollow handle pole (26), a handle (84) formed of a foamed polymer, and a device (36) for adjustably locking the handle pole (26) relative to the housing (14) of the floor maintenance machine (12). The locking device (36) includes a foot-operated lever (44) of a stamped, generally U-shape. The handle (84) is formed of a top section (90) and a bottom section (92), with hand grips (156) being integrally formed solely with the top section (90). Pivotable triggers (120) are pivotally mounted to cylindrical pivot bosses (118) formed in the handle (84), with unintentional pivoting of the triggers (120) being prevented by a slideably mounted, lock-out device (164). Trapezoid-shaped extensions (106) are formed on the bottom section (92) and include edges (108) for abutting with the floor when the handle assembly (10) is tipped to reduce the risk of the handle (84) cracking at the upper end of the handle pole (26).
A lawn mower, which is driven by an electric motor or an internal combustion engine, has an operation handle 80, which is formed by connecting through a grip part 82 rear ends of left and right long handgrips 81L, 81R extending rearward from the body of the lawn mower supported by wheels 6 and 7. A first operation member 84 is provided near a central portion of the grip part 82 of the operation handle 80, and a second operation member 85 is swingably supported by the operation handle 80. The second operation member 85 is arranged on the front side of the grip part 82 so as to freely move to and from the grip part 82. The lawn mower is driven by sequential operation of the first and second operation members 84, 85. Thus it is possible to constantly keep the lawn mower stable, enabling easy and quick operation, and improving operability.
