Definitions

• the present invention relates to an improvement of a vehicle wheel for which a tire is attached and used.
• Wheels of conventional vehicles are all made of an annular body with a substantially U-shaped cross section with a concave center, so that the attached tire has holes.
• the compressed air in the tires suddenly escapes, the shape of the tires is deformed, making it impossible to drive, and when the tires are in a parked state, the wheels rotate.
• the weight of the vehicle was applied to the protruding rims on both sides of the wheel, and the rim acted as a blade, resulting in the cutting of the tire.
• the damage to the tires during high-speed driving was very dangerous because it often caused the vehicle to lose its balance and to overturn the vehicle.
• the present invention solves these drawbacks, and even if the tire is damaged during traveling, it is a wheel that can maintain the balance of the vehicle and continue traveling.
• the purpose is to provide
• the wheel of the present invention has an annular body with rims on both sides, the ring with a larger diameter than the flange of the rim is located at the center of the outer periphery of the annular body. There is a protrusion! ? , The ring protrusion
• the shape of the annular protrusion depends on the vehicle type, size, and wheel width.
• the protruding part is formed on a curved surface because it is a flange at the end of the rim.
• the ring-shaped protrusion and the ring-shaped body may be formed integrally or separately, but the tip of the ring-shaped protrusion may be rubber or plus.
• the annular protrusion may be hollow, and when the annular protrusion is hollow, the annular protrusion may be provided with at least one air hole to compress it inside the tire.
• air may also be introduced into the annular protrusion.
• the air holes are designed so that sound can be produced by using the principle of the whistle while the compressed air gradually escapes from the tire, and the air is exhausted to the operator. You can also use this to get to know this sooner.
• the shape and size of the groove provided in the protrusion is different depending on the shape of the protrusion, etc., but is not particularly limited, but it is preferable to cut the protrusion diagonally and cut it upward.
• the area is narrow and the area below is wide.
• the depth of the groove naturally extends to the height of the flange of the rim or lower, but it is generally preferable to form the groove deeper as the annular projection becomes higher.
• the annular protrusion is more than about twice as high as the protrusion from the flange.

• a hollow metal ring-shaped protrusion (4) is attached to the center of a metal ring-shaped body (1) having ribs (2) on both sides. Therefore, the annular protrusion (4) is provided with an air hole (6) and a groove that diagonally crosses the protrusion (4).
• the groove (5) is narrow at the top and wide at the bottom (see Figure 3).
• This wheel can be used by attaching the tire (7) to the flange (3) of the rim (2) as shown in Fig. 2. Since the diameter of the bead part (8) of the tire (7) is D smaller than the diameter of the protrusion (4), but there is a groove, the tire (7) is attached to this wheel. Can be implemented in a stable manner. That is, push the bead part (8) and the side part (9) of the tire (7) into the body part (1) from one of the rims (2) of the wheel, and make a groove. Send to the other rim (2) through the (5)! ), And the tire (7) can be mounted over the protrusion (4).
• the plastic or rubber molded body ⁇ ) is made of natural rubber, various synthetic rubbers or synthetic resins such as NBRSBR, polystyrene, polyurethan, and polypropylene.
• the composite ⁇ ⁇ ) may be
• the molded body ⁇ may be mounted by only the holding force of the molded body ⁇ ) itself or by using a mounting means such as a bolt or an adhesive.
• the plastic or rubber molded body (10) can further absorb the impact when the tire is damaged.], And because it has appropriate elasticity, the tire (7) When it is punctured, it is possible to effectively prevent the tire displacement, and to significantly increase the stable mileage when the tire (7) is in the punctured state. Furthermore, the presence of plastic or rubber mold (6) increases the height of the protrusion (4) if the entire annular protrusion (4) is made of metal. There is also the advantage of being able to do this. As a result, it is possible to detect abnormalities in the tire (7) quickly, and even when the tire (7) is damaged, it is possible to travel with a diameter that is not significantly different from that of other tires (7). ..
• the plastic or rubber molded body (6) may form the entire ring-shaped protrusion (4) as shown in Fig. 7 ⁇ , but it may have the ring-shaped protrusion as shown in Fig. CDE. It may also be formed on the substrate ⁇ ) of part (4). In the latter case, the base body (11) may be formed integrally with the annular body (1) or separately, but it is preferably formed integrally. Furthermore, it is preferable that the plastic or rubber molded body ⁇ ) is a foam because of its weight and cushioning properties.
• the valley ti2) of the annular body (1) is formed deeper than the normal wheel, and the valley (13)
• the distance to the top (13) of the annular protrusion (4) is smaller than the diameter of the flange (3) of the rim (2) i? It is necessary for installation.
• the depth of the trough ⁇ may differ on both sides of the annular projection (4) as shown in Fig. 8, in which case at least one is formed to a predetermined depth. Goodbye.
• the wheel of the present invention is also useful for vehicles such as trucks, passenger cars, two-wheeled vehicles, bicycles, aircrafts, and other vehicles that have tires attached to them.
