Description

DETAILED DESCRIPTION OF THE INVENTION (I) The present invention relates to an in-vehicle rubber tire tube whose purpose is to completely prevent the in-vehicle rubber tire from bursting or being punctured (flat).

(II) Conventionally used rubber tires for automobiles often burst or go flat (flat), and especially when a tire bursts or goes flat while the car is running,
The reality is that serious accidents such as overturning have occurred. but,
To date, virtually no safety tires have been developed to prevent these tires from bursting or going flat.

(III) This is an epoch-making invention made by the present inventors to compensate for the above-mentioned drawbacks and to completely prevent tire bursting and punctures (flats). First, the tubes inside the rubber tire are multiplied and a large number of sub-tubes are installed to prevent wires or nails from getting stuck in the tire, and then getting stuck in the rubber tube, causing the air inside the rubber tube to escape and resulting in a puncture (flat). By making the length of one grandson tube stand up, the main tube installed at the center as well as the many grandchild tubes were able to run without any problems without punctures. On the other hand, inside the tire is an armor cover made of a carbon plastic material that is recognized to be harder than steel, which prevents nails and other objects from entering the tire and further protects the tire from exploding.

(4) Claim (I) of the present invention will be explained as follows from appendix FIGS. 1, 2, and 3. The inner ring part of the rubber tube that becomes the rubber tire peat part (
A parent tube (cover tube) with a simple adhesive band 14 that can be opened and closed is provided on the portion corresponding to the foil portion,
A flat child tube 1 consisting of one independent tube is provided in the inner ring portion (corresponding to the foil layer portion) of the parent tube 4.

On the other hand, a center grandchild tube 2 consisting of one independent tube is provided in the central portion of the parent tube 4. A sub-air valve 5 is connected between the center tube 2 and the tube 1 together with one umbilical tube 9. Next, around the center grandchild tube 2, a number of grandchild tubes 3 consisting of six or more independent tubes (12 in this example) are provided, and the center grandchild tubes are screwed so that they rotate exactly once each time the center grandchild tube goes around. It is installed by twisting and rotating it in the form of a twisted rope. At the contact point where the grandchild tube 3 and the tube 1, which are made up of multiple tubes, intersect at one point on one circumference by twisting rotation, these grandchild tubes 3 and the center grandchild tube 2
A total number of auxiliary air valves 5 are provided.

On the other hand, the auxiliary air valve 5 is opened and closed in conjunction with an air valve opening/closing manual screw (lot) 8 built into the main air inlet 7 of the sub tube 1 and an interlocking rod 6 for operating the auxiliary air valve. A safety tire with a multi-tube that can be operated freely.

(II) Claim (II) of the present invention will be explained as follows from appendix FIGS. 4, 5, and 6. A parent tube 4 (cover tube) with a simple adhesive band 14 that can be opened and closed is provided on the inner ring part (corresponding to the foil part) of the rubber tube that will become the rubber tire peat part, and the inner ring part ( A flat tube 1 consisting of one independent tube is provided in the portion corresponding to the foil portion. On the other hand, in the center of the parent tube 4, a center grandchild tube 2 consisting of one independent tube is provided. A sub-air valve 5 is connected between the center tube 2 and the tube 1 together with one umbilical tube 9. Next, around the center grandchild tube 2, 12 or more independent grandchild tubes are provided in the shape of a chrysanthemum petal so as to intersect and touch the center grandchild tube at right angles, and the grandchild tube 3 has a donut-shaped shape. do.

Sub-air valves 5 of the same number as the number of grandchild tubes are provided at the contact points where the grandchild tubes 3 and the child tubes 1 intersect. On the other hand, the auxiliary air valve 5 can be opened and closed in conjunction with an air valve opening/closing manual screw (lot) 8 built into the main air inlet 7 of the sub tube and an interlocking rod 6 for operating the auxiliary air valve. A safety tire with a multi-tube that can be operated at any time.

(III) Claim (III) of the present invention is defined as follows based on attached figures 7, 8, 9, and 10. A thin plate made of carbon plastic material, which is recognized to be stronger than steel, is molded into a small rectangular plate, and the butterfly plate 12 (
A steel wire 11 (or a strip of the same kind of material) is attached in a caterpillar-like armor shape vertically and horizontally to form an armor-like band 20, and the other side of this armor-like band 20 is made of carbon plastic. Thin linear band 1 made of fibers made of the same type of material.
In addition to woven into the outer layer 3, the epithelial surface is covered with rubberized carcass fibers and the same type of fabric as these armor-like bands 1.
The armor cover skewer, which is formed into a U-shaped belt so as to follow the carcass of the inner wall of the tire, is attached to the carcass of the inner wall of the tire and the rubber. A safety tire characterized by being sandwiched between tubes.

(5) The following will be explained again from the drawings based on the embodiments of the present invention.

(I) Regarding claim (I), the above (4)
When a car with safety tires manufactured as explained in Section (I) is punctured by a nail or the like while driving, the following actions will occur.

That is, the nail pierces the tire crown and further pierces the carcass, and finally reaches the rubber tube. Since tube 3 is present, by puncturing the grandchild tube, only one of the grandchild tubes will be punctured (flattened), but the other grandchild tubes will not be affected at all and the nail will not be able to reach the center grandchild tube. Normally, long objects such as nails and wires are bent before or during the insertion into the tire, so they cannot go straight to the center of the tube and enter at a right angle. This means that the intrusion will only be about 3cm long. Therefore, any nail or wire that penetrates the tube while running will only penetrate about 3 cm at most into the tube as described above, so naturally it will not be able to reach the center tube, so the center tube will not get punctured. In addition, if a nail or the like intrudes, of course only one grandchild tube in the part of the intrusion will be punctured, and the other grandchild tubes will not be affected at all and there will be no problem. In this example,
Since there are 12 subtubes, it was confirmed that when one of them becomes punctured, the internal air pressure decreases by only 1/24 (or less) and does not affect running at all. To repair a tire with a flat grandchild tube as described above, the simple adhesive band 14 of the parent tube 4 must be removed, and the child tube 1 and three groups of grandchild tubes built into the parent tube can be taken out and repaired. There is. Before performing the above repair, it is necessary to bleed the air from the tire tube, but this can be done by turning the air valve opening/closing manual screw in the main air valve 7 to open the auxiliary air valves of all sub-tubes and releasing the air. will all pass through. Furthermore, when a tube into which air has been injected becomes punctured as described above, the secondary air valve is closed, so even if the air pressure in only the punctured grandchild tube increases, the child tube and other grandchild tubes are not affected at all. It will not be done.

(II) Regarding claim (II), the above (
4) If a car equipped with safety tires as specified in paragraph (II) is pierced by a nail, etc. while driving, the above (5) shall apply.
This is exactly the same as item (I).

In this example, 16 inner tubes 3 are provided, so if one of the inner tubes is punctured by a nail, the tire internal air pressure will only decrease by 1/32, and there will be no problem with driving at all. It was confirmed that this did not occur. Other repairs and maintenance are the same as in (5) (I) above.

(III) Regarding claim (III), the situation when a nail etc. pierces a car equipped with safety tires as explained in (4) (III) above is as follows. . Nails that enter from the tire crown are completely protected by the armor-like band according to the present invention and are not penetrated into the tube at all, and the nails may break without being able to enter, or
It gets bent. Even if a nail or the like gets stuck in the tire, it is completely safe to drive. On the other hand, since the tube itself is protected by the armor-like band 10 and the thin wire-like band 13 within the armor cover band, it has been confirmed that it will not burst at all even if subjected to ultra-high pressure loads or shocks. Even if you intentionally stab the tire with a knife, the knife cannot penetrate the tube, so it is safe and will not cause a puncture.

(6) With the safety tire according to the present invention, there will be no punctures or ruptures while the car is running, and there will be no rollover accidents at all, which will not only save human life but also bring benefits to the transportation industry and society in general. is immeasurable.
