DESCRIPTION

INFLATABLE TIRE PADDING BY INTERNAL CHAMBER

OBJECT OF THE INVENTION

The present invention, as expressed in the wording of this specification, refers to a filling device for a tire, inflatable by means of a chamber arranged in its interior, which provides it with numerous advantages over the filling for a conventional non-endowed tire. this.

Tire filler is a type of foam that is installed inside some tires and is colloquially called "mousse" due to its fluffiness. It is basically used in motorcycle and bicycle tires for off-road use. This foam, characterized by being in the shape of a torus, is usually formed by microbubbles of the material itself containing nitrogen gas inside them to give the assembly flexibility that acts as a conventional chamber inflated with a certain pressure. This device is solid and does not house any type of device inside.

This pressure varies with the passage of time and the use of the tire. Due to deterioration of the mousse, the pressure drops until it is necessary to replace this mousse because it does not reach the minimum pressure for use.

At the moment that the mouse does not have a minimum pressure, no type of solution is available, which requires its replacement with the high costs that it entails.

In order to solve this problem, this utility model is presented.

BACKGROUND OF THE INVENTION

Various systems are known for providing pressure to the tires of vehicles of all kinds. From the traditional internal chamber that is inflated until the desired pressure is obtained for the tire, this being hermetic except for the inflation valve.

Also and mostly there are tubeless tires, these forming an airtight space between the tire and the rim to maintain the inflation pressure with a valve on the rim itself for inflation.

Likewise, there are devices made of flexible and porous foam-like material that produce a certain inflation effect in the event of a puncture of the tube installed in the tire that allow, although limitedly, to continue the journey.

When a puncture occurs in a vehicle, it is rendered useless for driving and that is why cars normally incorporate a spare wheel in order to solve this situation by changing the punctured wheel for the spare one.

There is also the aforementioned mousse that provides a certain pressure to the tire and is free of punctures, although on the other hand it has a series of drawbacks that are notably solved by the present invention.

DESCRIPTION OF THE INVENTION

In order to avoid this drop in tire pressure and not depend on the tire pressure on the physical state of the mousse, the present invention is described:

Until now, rubber air tubes have been used, which are what provide pressure to the conventional tire. Although there are also tubeless tires that are widely used, inner tubes are still used for motorcycles and off-road bikes.

These chambers are watertight and allow us to regulate said pressure, adding more or less air. The disadvantage of the same is that in the event of a scratch, pinch or perforation, they lose their tightness, they empty and the tire loses pressure.

We are faced with the typical puncture that disables the vehicle and does not allow us to continue the trip.

For this reason, mousses were developed, which are free of punctures and do not generate such a situation. But they carry other problems such as the lack of adequate pressure control and rapid deterioration. These mousses are commonly used on motorcycles and off-road bicycles because they are not suitable for riding on them.

To avoid the drawbacks of each of the systems (chamber and mousse), a conventional mousse is created characterized by having a chamber embedded inside. Once the mousse is mounted on the tire, it acquires a certain pressure that we can increase by injecting air or nitrogen gas inside the air chamber set up for this purpose.

Faced with the progressive deterioration of the mousse that causes a drop in tire pressure, we only have to add air or nitrogen through the valve provided for it to correct said pressure and said mousse, which in normal conditions should be replaced, dramatically increases its durability.

Also, the camera that when mounted in a conventional way is exposed to blows and punctures and is prone to being punctured. Here it is wrapped and protected by the mousse, which makes said puncture much more difficult.

Even if such a puncture occurred, the vehicle would not be immobilized since with the residual pressure of the mousse, the vehicle could continue its journey until it was repaired.

The mousse solves the problem of the lack of pressure control and its deterioration since the internal air chamber provides the necessary extra pressure which greatly prolongs the life of the mousse, adding air as the mousse deteriorates.

The camera solves the problem of punctures that cause the immobilization of the vehicle since, being embedded inside, it is much more protected against scratches, blows or penetrating objects.

DESCRIPTION OF THE DRAWINGS

To complement the description that is being made, and in order to help a better understanding of the characteristics of the invention, the present specification is attached, as an integral part thereof, to a series of figures in which, for illustrative purposes and not limiting, the following has been represented.

Figure! - shows a torus in schematic form to give an idea of the shape of the unmounted conventional mouse.

Figure 2.- shows a general view of two mousses, the one of the invention (B) where the air chamber from which the valve (A) of said air chamber appears on the inside. And a conventional mousse (C) is shown that does not incorporate said valve.

Figure 3a.- shows a section of the mousse without mounting, where the internal air chamber (B) appears with its valve (A) coming out. Figure 3b shows the section with a different arrangement of the air chamber. Both fulfilling the same task.

Geometrically, it would be like putting a thin torus with a smaller diameter (air chamber) (B), inside a larger toroid (mousse) (C), arranged in parallel.

Figure 4a.- shows a section of the complete wheel with the mouse (C) installed, where its shape would depend on the interior space between the rim (E) and the tire (D). By giving more air pressure to the air chamber (B), this would increase in size, generating a greater pressure that would be distributed throughout the mousse, thus achieving greater pressure on the wheel. Figure 4b shows the section with a different arrangement of the air chamber. Both fulfilling the same task.

Figure 5.- shows several cuts where the tire cover (D) also appears. Filling this, you can see the mounted mousse (C) which in turn has as filling the air chamber (B) with the inflation valve (A)

PREFERRED EMBODIMENT OF THE INVENTION

During the mousse manufacturing process, an interior hole is created where the chamber is introduced longitudinally through the interior of the toroid (mousse) and the valve is forced out of it.

The mousse is installed in the conventional way with the difference that the position in relation to the rim is determined by the valve outlet hole in the rim as in any conventional chamber and this position must be respected so that the valve can come out To the exterior.

Once assembled, if the tire pressure is lower than desired, we only have to inflate the tube so that the assembly acquires the appropriate pressure.

Claims (2)

1. Inflatable tire padding using an air chamber, characterized by having an air chamber (B) longitudinally embedded in the padding (C). 2. Inflatable tire padding by means of an air chamber characterized according to claim one in that the air chamber (B) has a valve (A) that protrudes from the outside of the rim once it is mounted, to be able to inflate or measure the pressure.
