Latest Patents

Among Takano's latest inventions is a state-of-the-art pneumatic tire. This tire features a tread portion with a distinctive shoulder land portion that includes a tread edge. The innovative design incorporates shoulder lateral grooves, which extend inwardly in the tire axial direction, defining shoulder block elements that improve the tire's overall performance. Additionally, he has introduced a unique protrusion from the outer surface of each shoulder land portion. This protrusion consists of first portions on the shoulder block elements extending in the tire radial direction and a second portion that connects inner parts of at least two first portions, enhancing tire stability and traction.

Another remarkable patent by Takano details a tire characterized by its zigzag shoulder main grooves that exhibit a trapezoidal wave form. These grooves comprise first and second circumferential segments along with first and second oblique segments. The shoulder axial grooves extend beyond the tread edges and smoothly connect to either the first or second oblique segments, creating composite shoulder axial grooves that increase in width towards the tire's axially outer side. This clever design contributes to improved handling and wear resistance.
