Latest Patents

One of Tetu Arai's latest patents is a floor polisher with a dust collecting device. This invention features a buffing pad that rotates at high speed, driven by a motor. It includes a circular cover member and a skirt that covers the upper surface of the buffing pad. The dust collecting device is designed to collect dust from the internal space surrounded by the cover member and the skirt. The unique aspect of this floor polisher is that the cover member and skirt are partly extended along a tangential line to create a guide chamber for dust-containing air currents. The guide chamber is equipped with a guide wall and an inclined plate that directs the air towards the floor, ultimately leading to an outlet port that communicates with the dust collecting device.

Another patent by Arai is a floor polisher that operates while traveling. This device causes a pad to rotate at high speed to polish the floor effectively. It incorporates a vertically moving mechanism that adjusts the pad's position relative to the floor. Additionally, it features a ground pressure adjusting mechanism that maintains a set pressure on the pad. A floor protecting mechanism is also included, which lifts the pad immediately when the floor polisher stops moving.
