Abstract
A floor finishing apparatus includes a chassis, a housing pivotably mounted to the chassis and having a mounting surface and at least partially defining a chamber, and a plurality of floor finishing units mounted to the mounting surface of the housing. The apparatus may include a rolling device carried by the housing and adapted to contact the ground to assist the housing in being pivoted with respect to the chassis.
Claims20
A floor finishing apparatus comprising:
- a chassis;
- a housing pivotably mounted to said chassis, said housing having a mounting surface, said housing at least partially defining a chamber;
- a plurality of floor finishing units mounted to said mounting surface of said housing;
- wherein said housing is pivotably mounted to a generally horizontal cross-member of said chassis;
- and
- wherein said chassis includes at least two uprights, at least one crossmember extending between the at least two uprights, and at least one support arm carried by the at least one crossmember, and wherein said housing includes at least one mount pivotally mounted to the at least one support arm.

A floor finishing apparatus comprising:
- a chassis including:
- at least two uprights;
- at least one crossmember extending between the at least two uprights;
- at least two wheels carried by at least one of the uprights or at least one crossmember;
- and
- at least two support arms having fixed ends attached to the at least one crossmember, being cantilevered from the at least one crossmember, and terminating in free ends;
- a housing pivotally mounted to said chassis and at least partially defining a chamber, said housing including:
- a mounting surface;
- and
- at least two mounts carried on the mounting surface and pivotably mounted to the free ends of the at least two support arms of the chassis;
- and
- a plurality of floor finishing units mounted to said mounting surface of said housing.

The floor finishing apparatus comprising:
- a chassis;
- a plurality of finishing units disposed frontwardly of the chassis;
- a handle coupled to the chassis and extending rearwardly from the chassis;
- a wheeled vacuum system, being coupled to the chassis, and extending rearwardly from the chassis with wheels of said vacuum system being behind the wheels of said chassis;
- a trailer carrying at least a portion of the wheeled vacuum system;
- a generally horizontally extending tow bar carried by the chassis to couple the trailer to the chassis;
- and
- wherein the chassis includes a crossmember, and the tow bar includes at least one mounting bracket adapted to be attached to the crossmember and an angle iron coupled to the at least one mounting bracket, wherein the angle iron includes a flange having at least one open slot therein.

A floor finishing apparatus comprising:
- a chassis;
- a housing pivotably mounted to said chassis, said housing carrying at least one floor finishing unit and pivoted to a first usable position with the at least one floor finishing unit resting on the ground;
- a handle and a first set of wheels coupled to the chassis to permit the floor finishing apparatus to move on said first set of wheels when said handle pivots said chassis to lift said housing off the ground when in the first usable position with respect to said handle;
- at least one rolling device carried by the housing and adapted to contact the ground to when the housing is pivoted to a second position with respect to the chassis;
- and
- said at least one rolling device is carried in proximity to a rear edge of the housing, such that a center of gravity of the housing and floor finishing units is over center to the rear of the pivot member to maintain a stable position of said pivoted housing when in the second position during rolling of the floor finishing apparatus.
