Abstract

The present invention discloses an emergency support device for tyres, formed by a retractable mechanism having a number of guides, an arm, a metal bar and a support; said mechanisms can be retracted and deployed as required by the user in case of emergency. When the retractable mechanism is activated and is deployed, it enables a vehicle to continue to be driven with the damaged tyre with no need to change the same, reducing the time spent waiting to reach one's destination or a tyre repair garage. Another advantage presented by the emergency support device for tyres is that the metal bar of the retractable mechanism has a covering that protects the integrity of the tyre as, if the puncture can be repaired, the tyre will not be damaged, as it would in the event of running flat. With the emergency support for tyres, the repair or replacement of the tyres may be performed without the need for special tools, and without it being necessary to remove the device of the present invention from the rim.

Description

EMERGENCY SUPPORT DEVICE FOR

Tires

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the technical field of mechanics and engineering, since it provides an emergency support device for tires.

BACKGROUND OF THE INVENTION

The tire, also called a tire, rubber or rim, is a part made of a rubber-based compound that is placed on the wheel of a vehicle to give it grip, stability and comfort. It is the only point of contact of the vehicle with the ground and, therefore, the tire depends to a large extent on the dynamic behavior of the vehicle, that is, how the vehicle moves on the ground.

The tire also largely depends on whether the wheel can perform its main functions, which are traction, steering, shock absorption, stability and load bearing. But for this to be possible, the condition of the tire must be correct, without cuts, cracks or deformations, and its inflation pressure must be adequate.

One of the basic characteristics of the tire is its elasticity, which is responsible for the tire being able to withstand the enormous efforts required by our daily driving, as well as its durability, and which guarantees that the tire will be able to perform its functions during its useful life. In addition, your grip must be correct on dry and wet.

Finally, the tire is responsible for much of the energy that the vehicle consumes to move. It is estimated that 20% of the fuel used by a vehicle is lost in the tires. For this reason, a tire designed for efficient use and maintained at the correct inflation pressure will contribute to greater energy savings.

It is worth mentioning that the life of a tire is limited, not only limited in terms of wear on the tread pattern, but also the degradation of the rubber. Actually, the chemical compounds that are part of the tire are studied to last. However, over the years its properties deteriorate until it loses its characteristic elasticity.

A wear time of five years is usually recommended if the tire has been well preserved. On the other hand, puddles with traces of fuel or solvents, prolonged exposure to the sun or ozone fumes, for example, can contribute to premature tire degradation, other types of aggressions, such as hitting curbs, can end with its internal structure in a very short time.

Undoubtedly, the invention of today's tire facilitated the transportation process in the world, but it also brought with it several problems, including the conflict of punctures or punctures. It was not until the late 1990s that the first anti-flat tires were introduced to the international market and marketed for almost a decade. This tire that promised to solve the flatness problem turned out not to be 100% effective and that it was only capable of retaining sharp objects that were smaller than five millimeters, so any object larger than this measure penetrated the reinforced layer. Another problem that this tire presented in its first years of commercialization was that when it went flat it was impossible to repair it, so the consumer was forced to buy a new tire.

Another of the alternatives that were presented in the market, are vehicle tires that can be rolled even without air, because unlike traditional tires that support the weight of the car from the pressure at which they are inflated, they have reinforced sides and an internal support where the tread is supported when it lacks pressure.

Additionally, the reinforced sides are made with a type of rubber that helps them maintain their shape and allows them to support the weight of the car even when it is flat. In this way, you can advance a distance of 80 kilometers at a speed of 80 km / h until it can be repaired.

A search was carried out on the state of the art for an emergency support device for tires, where it was found that different devices have been developed for this purpose, as mentioned in patent application document number CN108099490 (A), published on 01 June 2018, with the title "NEW ANTI-EXPLOSION WHEEL CENTER", which describes a new anti-explosion wheel center; which includes a body in the center of the wheel and multiple anti-explosion units; the wheel center body consists of a rim and a spoke, and each explosion-proof unit comprises a first fixing plate, a second fixing plate, a first supporting column connected with the first fixing plate, a second supporting column connected with the second fixing plate, and a curved plate connected with the first supporting column and the second supporting column, in the that the section of the curved plate is arc-shaped, and a rubber pad is attached to the outer side wall of the curved plate; the first fixing plate is attached to the rim through the first bolts, and the second attachment plate is installed on the rim through the second bolts. The center of the wheel has an anti-explosion effect.

Another document that was found is the patent application number CN107627784 (A), with publication date of January 26, 2018, which is titled "ANTI DEVICE

EXPLOSION FOR AUTOMOBILE WHEEL TIRE CENTER

SPLIT OR INTEGRAL ", where an anti-explosion device is described for the center of a split or integral car tire. The key technical scheme is to increase the diameter of an existing wheel center, so that the enlarged part can become a frame round, the diameter of which is slightly smaller than the external diameter of a rubber tire; the structure can rotate with wheels, but it has no contact with the ground, so the critical distance of the tire damping cannot be affected; a Once the rubber tire explodes, the height is rapidly reduced, so that the split, fixed or integral structure, can land, balance and move forward stably; and the detestable results of vehicle body imbalance due to sudden turns of the vehicle, can avoid intense shaking. Document number CN201333899, published on October 28, 2009, was also found with the title "CENTER OF EXPLOSION PREVENTION TIRE", which refers to a tire center for the prevention of explosions that includes a rim. The center of the blowout prevention tire is characterized in that a support ring fixedly connected with the wheel rim is arranged along the periphery of the rim. Because the support ring is arranged on the wheel rim, once the tire burst occurs, the support ring with a larger diameter, instead of the wheel rim, is in contact with the ground; And since the diameter of the rim does not change and the contact area of the support ring and the ground are simultaneously increased, the possibility of losing control of the vehicle is greatly reduced and the safety performance of vehicles is improved compared to prior art.

Finally, patent document number KR101835465 (Bl) was found, with publication date of March 08, 2018, which has as title "HINGE TYPE TIRE EMERGENCY SUPPORT APPARATUS", which makes mention of a support device emergency hinge-type tire blowout device comprising a plurality of strap bodies, a first connecting head, a second connecting head, and a plurality of support apparatus. The adjacent belt bodies are movably connected. One end of the first connection head is movably connected to the strap bodies. One end of the second connection head is connected to the strap bodies, and the other end is connected to the first connection head. The plurality of support apparatuses are arranged separately on the inner radial surfaces of the plurality of belt bodies and is used to support the plurality of belt bodies after bursting of the tire, to support the tire. A chain strap apparatus for connecting the first connecting head, the second connecting head and the plurality of belt bodies is covered with an outer edge. The hinge type tire escape emergency support apparatus is convenient for mounting and dismounting.

None of the aforementioned documents shows evidence of having a support mechanism that is fixed to the outer base of the rim of a vehicle, which are retracted until the tire suffers damage, nor does it mention that the bars are deployed to allow that the vehicle can continue moving without the need to replace the damaged tire.

There is also no evidence that they are retractable and that they facilitate tire repair or replacement in a conventional manner without the need for special tools.

OBJECT OF THE INVENTION

It is therefore an object of the present invention to provide an emergency support device for tires, which solves the aforementioned problems.
