Abstract

This invention consists of varous tyre (1) types, which encircle the especially formatted metal rims of the wheels. Those tyres from structure they bring, at the inner part, along the perimeter, vertical, devious-parallel and diagonal opposite, symmetric or asymmetric rubber partitions with formatted edges for to be applicable in the cavities which are created by the union of the different sections of the metal rim, in order to create multiple and independent air-chambers. The basic advantages are: more safety in a case of a flat and damaged tyre, the firmness and the perfect grip against the reciprocation and deformations that great speed creates due to the increasing temperature, the easier and quicker replacement [(divided rim) Fig.10], without using expensive and heavy equipment, and last but not least the earning of time and money. Also the ecological benefits that we have, because those tyres can be made from recycling the old and unused ones. The basic concept of this invention is the creation of the inner partitions.

Description

VEHICLE WHEELS

The specific invention refers to the wheels, which are used to move and propulse vehicles. Wheels are one of the most critical part of a vehicle. They come in many different types according to usage. Each wheel combines of a metal rim which is surrounded by the tyre which detains the air, when we inflate the tube through a valve. The use of the specific type of wheels comes with a number of advantages and disadvantages. The soft and sockless movement on the road surface can be an advantage. On the other hand a great disadvantage is that when total destruction of the wheel, after a flat tyre, occurs while in movement, regardless vehicles' speed. Also in the disadvantages category is the necessary equipment acquired for a flat tyre to be replaced, and the physical strength needed for this purpose. In a few words, the method above requires time, effort, expensive equipment and powerful hands. One, of this inventions' task, is to eliminate those factors. A greater task is to increase safety in a case of a flat tyre: according to this invention, multiple air-chamber tires are structured due to detain air pressure, 15% minimum up to 85% maximum. As a result we succeed the firmness due to reciprocation and deformations of the tyre during vehicles' high speeds, due to the increasing temper- ature.

Metal rims were designed to fit those tyre's, in a variety of types, for all kind of usage, on or off-road. Appended figures present in a lucid way technical information, which will help the industrial application when manufacturing the above. This invention can be easily understood by the clear and in great details presentation in figures in which:

Plan 1 shows a section of the tyre and rim which is structured with multiple air-chambers according the appendix. Plan 2 shows a perspective section of the tyre with multiple air-cham- bers according to plan 1.

Plan 3 shows a perspective section of how the tyre fits to the metal rim. Plan 4 shows a perspective section of the tyre and presents the cham- ber combination (A-B-E-G), of the example in page 6 paragraph 4.

Plan 5 shows a perspective section of the wheel and presents the chamber combination (A-B-E-G), of the example in page 6 paragraph 5. Plan 6 shows a perspective section of the tyre and presents the chamber combination (A-B-C-C-C-G), of the example in page 7 paragraph 1. Plan 7 shows a perspective section of the wheel and presents the chamber combination (A-B-C-C-C-G), of the example in page 7 paragraph 2. Plan 8 shows a perspective section of the tyre and presents the chamber combination (G-F-G), of the example in page 7 paragraph 3. Plan 9 shows a perspective section of the wheel and presents the chamber combination (G-F-G), of the example in page 7 paragraph 4. Plan 10 shows in section the link of the divided metal rim [(5-8) Fig. 10], and how is adjusted to the tyre.

Plan 1 shows in great detail the section of a vehicle's' air-tube, attached to a firm metal rim, which is structured with multiple air-chambers (H-J-K-L-M-N-P-Q). This can be achieved by formatting the inner partitions (2-3-4-5-6-7), with a spiral twist at its ending (8), due to be adjusted by bolting it to the metal rim (26). And the purpose of that is to detain the air pressure 15% minimum up to 85% maximum, in case of a flat tyre, which leads to an unstable and unsafe handling of the vehicle during high speed by the alongside powers applicated, and also to absorb the shocks which are created by the road-surface and last but not least to manage to retain the tyre on the wheel during a puncture. Also we can achieve of having positive formations of the tyre by the valve which exists and orders, according to the gear lever and the grip of the vehicle, to inflate with air (37), each and separate airtight chamber. As a fact we have the advantage of mounting the tyre (1), to the divided rim [(26) Fig. 1], in an easier way. Next we clarificate many example of this invention with plan (1). In details: The tyre (1), from structure is divided to multiple chambers through the devious and vertical inner partitions (2-3-4-5-6-7). This partitions are perimetrically linked together and along the perimeter with the embodied drilled metal rims (24-29-32-35), which are manufactured by plastic or metal or any other similar artificial material which is wrapped up with another artificial material.

This rim keeps firm the inner partitions (7-6-5-4-3-2) . During the placement of the tyre on the metal rim, the spiral formatted ending of the partition (7), screws and adjusts to the cavities (42-41-40-39-38), its formatted endings (17-34-31-27-23), of the inner partitions. The result of this application is that the tyre remains in position whether is flat or destroyed. To be explicit i gathered and classificated the tyre (1), in sectors (Fig. 1-2-3), which are: (A-B-C-D-E-F-G). Sector (A), demonstrates the outer part of the tyre (9), which is bigger than the inner part (10). Sector (B), demonstrates the spiral formatted ending of the inner partition (7) , in addition to bolt it on the metal rim. Sector (C), demonstrates a small air-tight chamber (J), without valves, these soft parts (20), of the tyre (1), provide good grip on the road when they retreat by the pressure and the small chamber (J), which extends perimetrically and along side the perimeter absorbs the shocks which are cre- ated by a bad road surface. Sector (D), demonstrates a devious inner partition (6), and its formatted ending (34), which adjusts to the cavity (41), of the metal rim. Sector (E), demonstrates two air-chambers (M- N), which the devious inner partitions (5-3), surrounds them and the drilled (36), diagonal partition (4), which keeps the tyre firmly from the alongside powers during high speed.

We can also see the formatted endings of the inner partitions (31-27), which end to cavities (40-39), on the metal rim and the valve which is been placed to a hollow spot on the surface (19), which gives the formation needed for the best grip by inflating (37), each and separate air-chamber. Sector (F), demonstrates vertical inner partition (2), and its' formatted ending (23), which adjusts to the cavity (38), on the metal rim. Sector (G), demonstrates the inner part of the tyre. For the industrial application of the above this invention (tyre & rim), has the capability of creating lashings of different combinations by using its sector separately, or we can use as many sectors appended as we wish. For example we use sectors (A)-(B)-(E)-(G), to structure a tyre and (A)-(B)-(C)-(C)-(C)-(G), to create another. Steel we can for- mate a tyre which has isosceles edges by using sectors (G)-(F)-(G).

According to the above we can choose a tyre which has two -three or even more air-chambers. We use plan 1 to accomplish the formation and we avoid the numerous combinations that we can choose because we don't want to «load» the future reader and also the organizations would have not accepted it.

Placement of the tyre is to be succeeded easily by the following instructions.

After we mount part (10) of the tyre, at the outer section of the wheel (11), on the rim(16), by bolting the tyre to efficiently attach to the spiral twist (21), of the metal rim (26), by applicating the formatted endings (23-27-31-34-17), to the equivalent cavities (38-39-40-41-42), the edge of the tyre is now adjusted to the terminal (15). Next by using Levers we adjust the limb (9), and the edge (13), to the terminal (12). Also special signs are to be provided on the rim and on the tyre which will help mounting the tyre. Next step after we make sure that the edges are correctly adjusted to the terminals we can pump air (37), in stages through the valves (28), which every air-chamber has. Air pressure increases the air-tightness of the equivalent partitions to the points (22- 25-30-33-18). Mounting the tyre to the rim can be achieved according the way described above.

Plan 2 shows a section of a tyre of plan (1), with a new combination (7- 6-5-4-3-2), of the inner partitions, the formatted edges , the embodied (plastic or metal), drilled rim, the spiral twist (8), of sector (B). Also we can see sectors (A)-(C)-(D)-(E)-(F)-(G), chamber (H), the small anti- shock chamber (J) of the (K)-(L)-(M)-(N)-(P)-(Q) and the differentiation of the side limbs (9-10).

Plan 3 shows a perspective section of a metal rim and tyre. In order to make it easy to the reader we use some identical factors of plan 1 such as the multiple air-chambers (Q-P-N-M-L-K-H) , the outer part (1 1), the inner part (13) , and the spiral twist (14) on the rim. The drilled embodied perimetric rims, the valve (12), which is placed on a hollow surface section of the metal rim and the differentiation of the side limbs of the tyre (9-10), last we see sectors (G)-(F)-(E)-(D)-(C)- (A)-(B).

Plan 4 shows a perspective section of the tyre with the chambers combination (A)-(B)-(E)-(G), which have specially formatted rubber inner partitions, we can also see the unequal edges of the tyre and the spi- ral twist along the perimeter of the tyre, and also the diagonal inner partition.

Plan 5 shows a perspective section of the wheel. In order to make it easy to the reader we use some identical factors of plan 4 such as the airchambers of sections (A-B-E-G), the metal rim with a spiral twist for the tyre to be bolted, and also the valve.

Plan 6 shows a perspective section of the tyre with the chambers combination (A-B-C-C-C-G), the especially formatted rubber inner partitions which are devious and parallel, the small chambers which are airtight by structure (no valves required), through large air chambers and the tyre's pad, also the specially formatted devious edges of the tyre. Plan 7 shows a perspective section of the wheel. In order to make it easy to the reader we use some identical factors of plan 6 such as the airchambers of sections (A-B-C-C-C-G), the metal rim with a spiral twist for the tyre to be bolted, and also the valve. Plan 8 shows a perspective section of a isosceles tyre with the chambers combination (G-F-G), which has two equal airchambers, and also, the inner rubber partition with a specially formatted forked edge. Plan 9 shows a perspective section of the wheel. In order to make it easy to the reader we use some identical factors of plan 8 such as the airchambers of sections (G-F-G), the metal rim which has in the middle and along the perimeter, a dactyl form nerve for the forked edge to be adjusted. Plan 10 shows a section of the main limb (8), of the metal rim and how is adjusted with the outer limb (5) , and the perimetrical (plastic or metal), rim.

In details the main limb of the rim (8), with especially formatted cavities (7), has a spiral twist (6), in which the perimetrical rim (3) bolts to, and simultaneously presses the inner partition (2), to the formatted cavity (7). Then the outer limb (5) , bolts to the spiral twist of the main limb (8). In order to increase safety an o-ring (10), and secure bolts (9), are provided. The purpose of it is to obtain firm application (4), to the perimetrical rim (3), due to obtain airtigthness to the airchamber. As a result the mounting of the tyre (1) becomes much easier.
