Title: Spike tire
Inventor: MAEDA TADASHI
IPC: B60C11/16
Filed: 1987-12-31
Abstract: PURPOSE:To prevent both a tire slip and road surface damage by providing a spike pin in the tread of a tire in such a way as to allow the free projection or retreat thereof via a brake means and the like, and causing the spike pin to come in and out of the bread depending upon the occurrence and non occurrence of a tire slip. CONSTITUTION:When a tread 10 comes in pressed contact with a road surface, a movable body 9 while turning is pushed upward to the inside of a support body 5, thereby compressing an elastic body 8. Also, the pressure of a brake elastic body 4 and road surface pressure on a spike pin 1 work upon a spike pin pressurizing part 2, and this force applies a frictional engagement face between a brake 3 and the support body 5. And the brake 3 does not turn and the spike pin 1 coupled to the brake 5 via a keyway 7 does not turn as well. As a result, the spike pin 1 as prevented from projection due to the spike pin pressurizing part 2, stings the road surface, thereby preventing the slip of a tire proper 11.
