Deformed tire

The present invention is a tire, and more particularly to a tire having telescopically elastic spokes.

The tire is made of a circular object, which can rotate around the axis and pass through the rolling, which greatly reduces the friction. If it is equipped with the axle, it becomes the most important part of various vehicles. Tires are very useful in transportation and are one of the important inventions of human beings. The tires are mainly composed of a wheel frame including spokes and a rubber carcass.

In a typical tire structure, the rubber carcass is formed in a circle form to facilitate the rubber carcass to be placed on a wheel frame. Usually, the wheel frame has a plurality of spokes, and the plurality of spokes are usually fixed on a central structure, so generally installed A tire-equipped vehicle is used to allow the vehicle to walk on a flat surface. When encountering a terrain with a height difference such as a staircase, the tire is usually not applicable. In other words, the general tire does not have the function of climbing or climbing, when the tire does not have When climbing or climbing, it is inconvenient in some vehicles. For example, a lighter vehicle such as a bicycle or a wheelchair, especially a wheelchair user, is inconvenient because of its own feet. Wheelchairs that do not have the ability to climb or climb will cause great trouble.

For the above reasons, how to further form a deformed tire based on the spokes having elasticity and elasticity to have a function of climbing or climbing is a problem to be solved.
