ABSTRACT:
A floor polishing machine (10) according to the preferred form of the teachings of the present invention includes a body portion (12) having a platform (20), and a handle (16) pivotally mounted to the platform (20). First and second sets of wheels (68, 70) are provided adjacent the rear of the platform (20) and on opposite sides of the handle pivot (50). For coupling the handle (16) and the platform (20) together, a gas spring (53) is provided having a first end pivotally connected to the platform (20) and having a second end pivotally connected to the handle (16). The gas spring (53) urges the platform to pivot about the first set of wheels (68) downwardly in the rear and upwardly in the front. The motor (24) for rotating the polishing member (14) is pivotally mounted to the platform (20) by ears (23) so that the polishing member (14) can flushly abut the floor surface. The handle (16) is latched in an upright transport position by a pin (59) received in the first leg (85) of an L-shaped slot (81) formed in a latch (74) pivotably mounted to the platform (20) and is allowed to pivot in operating positions when the pin (59) is received in the second leg (83) of the L-shaped slot (81). The latch (74) includes a cord hook (77), with the spacing between the handgrip (89) of the handle (16) and the cord hook (77) being less in the operating positions than in the transport position so that an electric cord (87) wrapped around the handgrip (89) and the cord hook (77) can be removed without unwrapping when the handle (16) is moved from its transport position to an operating position.
