Abstract

PURPOSE:To increase an edge effect for reducing slip and slide on a frozen road surface and slippy road surface by providing hard rubber on the tread surface of a studless tire to provide a star shaped pattern, a round recess in the center of the star shape and grooves extending from the recess to the tip of the star in the 5 directions. CONSTITUTION:Hard rubber 1 is provided on the outer peripheral tread surface of a studless tire to provide a star shaped pattern 2 therein, a round recess 3 in the center of the star shaped pattern 2 and grooves 4 extending from the recess 3 to the tip of the star shaped pattern 2 in the 5 directions. Thus, even if the studless tire is in a crushed state by the contraction of air therein in the low temperature, the whole star shaped pattern 2 is not crushed, but the tip of the triangle is crushed and the periphery of the round recess 3 is not crushed to provide an upheaved projecting condition. Thus, the edge effect is increased in the use of a brake, and slip and slid conditions on a frozen road surface and slippy road surface can be reduced.

運転に関する分野の発明品です。BACKGROUND OF THE INVENTION The present invention uses (1) hard rubber on the ground contact surface of a statless tire, (2) a star-shaped pattern is installed, and (3) a star-shaped center has a round depression. (4) Make grooves in five directions from the round depression toward the tip of the star. The product of the present invention is a product in the field of safe driving of a vehicle, which is intended to improve the braking force of a statless tire used in a vehicle in winter.

欠点が有ります。2. Description of the Related Art Conventional statless tires have a soft rubber material and the shape of the pattern is similar to a square shape. At low temperatures, the tires are crushed due to the contraction of the air pressure inside the tires. There is a drawback that the braking force decreases on a frozen road surface or a slippery road surface and the vehicle becomes slippery.

発明で解決するのが課題です。[Problems to be solved by the invention] The problem to be solved by the invention is that since soft rubber is used, it is soft and the corners are easily crushed, and the pattern is often similar to a square shape. When a brake is used, it becomes a state of shogi backwards. It is an object of the present invention to solve the drawback that the braking force on a frozen road surface or slippery road surface is reduced and the vehicle is in a gliding state.

The products of the present invention were applied to the ground contact surface of a statless tire as follows: (1) hard rubber (2) star pattern (3) round recess in the center (4) grooves in five directions The example in which the pattern was attached and used was that the air inside the tire at low temperature contracted and the tire collapsed, the entire pattern did not collapse, the tip of the triangle collapsed, and the area around the depression did not collapse There is an example in which it becomes a spread protrusion state and the edge effect is increased on the road surface to reduce slip and gliding condition on frozen road surface and slippery road surface.
