WEN-FU CHIU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A tire is disclosed, including a plurality of blocks, each has an outer surface bulging outward and two lateral walls. An extension line is defined on the surface of each flat segment of each block. Each extension line has a first point on the flat segment. A first horizontal reference line is defined by connecting two first points. A second horizontal reference line is defined on the outer surface with two ends thereof contacting the outer surface. The second horizontal reference line is 0.85 times as long as the first horizontal reference line. A vertical distance between the outer surface and the second horizontal reference line is 0.2-0.8 mm. Whereby, the tire could provide good drainage performance and adequate grip.
