Abstract

A tire for a vehicle has a structure in which a plurality of air blocks are detachably mounted in a circumferential direction of the tire. The tire is similar to an airless tire, in which a plurality of spokes are connected to and arranged between a tread rim part configured to come into contact with a road surface and a hub which is mounted to the wheel, and the tire is also similar to a pneumatic tire, in which an air block is replaceably inserted and mounted into an air block mounting space formed between the spokes.

First claim

What is claimed is:

1. A tire for a vehicle, the tire comprising;
a tread rim part configured to come into contact with a road surface;
a hub to be mounted to a wheel;
a plurality of spokes connected to and arranged between the tread rim part and the hub in a circumferential direction;
an air block mounting space formed between the spokes to be arranged in the circumferential direction; and
an air block which is detachably inserted and mounted into the air block mounting space,
wherein the air block mounting space comprises a locking structure configured to prevent the air block from being detached,
wherein the locking structure is an elastic locking plate, and the elastic locking plate is detachably mounted on an entrance of the air block mounting space to lock the air block inserted into the air block mounting space,
wherein at the entrance of the air block mounting space, the tread rim part and the hub have locking grooves formed therein, and both end portions of the locking plate are inserted and coupled into the locking grooves, respectively, and
wherein the locking plate is configured to have an elongated rectangular plate structure which can be bent and has an elastic restoring force.

2. The tire of claim 1 , wherein the spokes and the air block mounting space are alternately arranged in the circumferential direction.

3. The tire of claim 1 , wherein the air block has a size filling an internal volume of the air block mounting space.

4. The tire of claim 1 , wherein stopper steps for preventing a detachment of the air block are further formed on a portion of the tread rim part which forms an upper portion of an opposite opening of the air block mounting space, and on a portion of the hub which forms a lower portion of the opening, respectively, and the stopper steps are integrally formed with the tread rim part and the hub, respectively.
