Patent Images
1. A floor polisher having a pad and means for causing, while the floor polisher is travelling, said pad to rotate at a high speed to polish a floor, said floor polisher comprising:
- a vertically moving mechanism adapted to move said pad in the vertical direction with respect to the floor;
a ground pressure adjusting mechanism connected to said vertically moving mechanism for maintaining a ground pressure of the pad at a set pressure by controlling said vertically moving mechanism; and
a floor protecting mechanism connected to said vertically moving mechanism for controlling said vertically moving mechanism to lift the pad immediately when the travel of the floor polisher is stopped.

Abstract
A floor polisher, while travelling, causes a pad to rotate at a high speed to polish a floor. The floor polisher has a vertically moving mechanism adapted to move the pad in the vertical direction with respect to the floor, a ground pressure adjusting mechanism adapted to maintain a ground pressure of the pad a set pressure by controlling the vertically moving mechanism, and a floor protecting mechanism adapted to actuate the vertically moving mechanism to lift the pad immediately when the travel of the floor polisher is stopped.
