Abstract

A floor coating agent applying machine having a movable machine body, an applying member attached to the movable machine body for applying a floor coating agent onto a floor surface. The applying member includes a plurality of elastic rods vertically suspended from the movable machine body, with the rods being arranged in a loop-like formation as viewed from above the movable machine body, an eccentric rotary cam drivably attached to the movable machine body and rotatable on a vertical axis positioned inside the loop of the elastic rods and a circular recess vertically slidably fitted about the eccentric rotary cam so as to cause a rotational force of the cam to elastically deform the elastic rods thus producing vertical vibration of the applying member.

Claims

1. A floor coating agent applying machine comprising:

a movable machine body;

an applying member attached to said movable machine body for applying a floor coating agent onto a floor surface to be treated;

an applying member driving mechanism attached to said machine body by elastic rod means, said applying member driving mechanism causing said applying member to vertically vibrate and laterally oscillate along the floor surface; and

means for drying said coating agent mounted to said applying machine, said means for drying comprising a first drying means and a second drying means, said first drying means being positioned behind said applying member and directing hot air toward said floor surface, said second drying means directing air of ambient temperature toward said floor surface subsequent to said first drying means.

2. The floor coating agent applying machine as claimed in claim 1, wherein said applying member includes an elastic element and an applying-face forming sheet surrounding said elastic element.

3. The floor coating agent applying machine as claimed in claim 2, wherein said applying member further includes a water-retentive element interposed between said elastic element and said applying-face forming sheet.

4. The floor coating agent applying machine as claimed in claim 1, wherein said applying member is formed of water-retentive material.

5. A floor coating agent applying machine comprising:

a movable machine body;

an applying member attached to said movable machine body for applying a floor coating agent onto a floor surface;

said applying member including;

a plurality of elastic rods vertically suspended from the movable machine body, with said rods being arranged in a loop formation as viewed from above the movable machine body,

an eccentric rotary cam drivably attached to the movable machine body and rotatable on a vertical axis positioned inside said loop of the elastic rods, and

a circular recess vertically slidably fitted about said eccentric rotary cam so as to cause a rotational force of the cam to elastically deform said elastic rods thus producing vertical vibration of said applying member.

6. A floor coating agent applying machine as claimed in claim 5, wherein said rods comprise four rubber rods forming said loop.
