Title of Invention | PUNCTURELESS TYRE/TUBE |
---|---|
Abstract | A punctureless tyre/tube for ensuring that a punctured tyre does not render an automobile immovable, neither in short-term nor in medium-term. The punctureless tyre/tube comprises of plurality of spherical air capsules 4 comprising of light plastic/rubber material 3, tightly filled inside the conventional tyre 1 so that when a nail/sharp object pierces through tyre l, all the air in the plurality of air capsules does not get released at once or slowly and instead, only a very small fraction of air i.e. air of only one air capsule 4 escapes, ensuring that the automobile continues to remain fully functional in terms of its movement on the wheels. This invention also helps eliminate the valve which is useful in regular checking/re-inflation of conventional tyre/tube as each of the plurality of air capsules 4 in this invention are sealed units made of impermeable light plastic /rubber material 3. |
Full Text | This invention is related to PUNCTURELESS TYRE/TUBE for automobiles. Known Art Tyre/tube of the prior known art have a typical arrangement where an inflatable tube is pressurised with air and positioned inside a tyre to provide cushion to an automobile. But when any nail/sharp object pierces through the tyre, the tube gets punctured, resulting is sudden release of air, rendering the tyre/tube anangement not usable. The automobile has to be stopped and the tyre/tube replaced or repaired, before the automobile can move again. Another known art is the tubeless tyre where air is locked inside the tyre body itself, with sufficient sealing ensured at the point where the tyre sits on the rim, and a valve body is provided on the rim so as to facilitate inflating/deflating of the tubeless tyre. But here again, when any nail/sharp object pierces through the tyre, a micro hole gets formed for release of air, although slower, if not sudden release of air, again leaving the tyre unfit for use in a somewhat longer term. In any case, the embedded nail/sharp object must be removed at the earliest so as to avoid permanent damage to the tyre. Disadvantage of the known art This prior known art has following disadvantages: a. In case of tyre/tube arrangement, any nail/sharp object, punctures the tube instantaneously leaving the tyre/tube not usable, forcing the automobile to an instant halt. b. In numerous cases, this results in accidents. c. In case of tubeless tyres, any nail/sharp object piercing the tyre also forces the air to release although at a somewhat slow and steady rate. Moreover, at the earliest possible, the nail/sharp object must be removed and the hole thus caused in the tyre, must be sealed back. If not removed, this nail/sharp object which is embedded in the tyre causes further damage to the tyre. d. Occasional/slow leakage of air from the valve nozzle necessitates re-inflating of the tyre/tube air pressure, on a regular basis. Brief description of the accompanying figures/drawings. Fig 1. Represents a cross-sectional view of the invention of punctureless tyre/tube. Fig 2.

Fig 3. Representing a cross-sectional view of the conventional tyre/tube shown wherein are the tyre (1), the rim (2), the tube (3), the air (4) contained inside the tube (3) and the valve (7). Fig 4. Representing a cross-sectional view of conventional tubeless tyre shown wherein are the tyre (1), the rim (2) the air (4), contained inside the tyre (1) and the valve assembly (7). Object of this invention It is the object of this invention to devise a pneumatic air pressure arrangement in the tyre so as to obviate the aforesaid prior art defects and to ensure that any piercing nail/sharp object in the tyre does not render the automobile immovable-whether immediately or in the long-term, thus saving the automobile user from losing time, money and most importantly safety, by avoiding accidents. Accordingly, the invention prorides for a punctureless tyre/tube characterized in that it comprises a number of round spherical air capsules/bubbles(4) contained in an optimum plastic/rubber material (3) inside the tube (1) and the rim (2) which is titted with a screwable cap (7), for filling bubbles (4) inside the tyre (1) which is capable of bearing temperature prevailing inside tyre (1) when the tyre is in motion and to provide the required air cushion for an automobile wheel. The invention helps in keeping the tyre functioning even if a nail/sharp object has got embedded in the tyre as it will cause puncturing of only one or two air capsules/bubbles at one time and arching would take place to ensure no further puncturing of other air capsules/bubbles. As a result, it would prevent a release of total air and deflating while in motion. Thus the basic concept is to divide the cushioning air into multiple compartments in the form of round spherical air capsules/bubbles encased in a flexible material so as to ensure that one puncture means puncture of one or two air capsules/bubbles and prevent the release and loss of the entire air at one go. The invention is explained with reference to the accompanying sketch wherein it shows the punctureless tyre/tube arrangement where tyre (1) is attached to the rim (2) and inside the space available, air (4) is contained inside small round spherical capsules/bubbles (3) made of flexible material. These air capsules/bubbles (3) are stuffed in this space between the tyre of the tubeless tyre, and the rim (2). When a nail/sharp object(5) gets embedded in the tyre, one air bubble gets punctured (6) and the thus vacated space remains blank, as the surrounding air capsules/bubbles remain in their position, forming an arch ensuring that one punctured air capsule/bubble has no affect on the overall cushioning characteristics of the tyre. Periodically, during automobile servicing, position of these air capsules/bubbles can be examined and necessary replenishment done, through a capped opening (7). Advantages The invention ensures that in case a nail/sharp object pierces through tyre, all the air inside the tyre does not get released at once or slowly, and instead, only a very small fraction of it i.e only one or two air capsules/ bubbles get burst, ensuring that the automobile continues to remain fully functional in terms of its movement on the wheel. The invention helps eliminate valve and the need for any regular checking/re-inflating of tyre/tube as in case of prior art, conserving energy by way of this prevention of loss of any pressurised air. I CLAIM 1. Punctureless tyre/tube characterized in that it comprises a number of round spherical air capsules /bubbles (4) contained in a light plastic /rubber material (3) inside the tyre (1) and the rim (2) which is fitted with a screwable cap (7), for filling air bubbles (4) inside tyre (1) which is capable of bearing temperatures prevailing inside tyre (1) when the tyre is in motion and to provide the required air cushion for an automobile wheel. 2. A puntureless tyre/tube as claimed in claim 1 wherein an opening (7) is provided in the rim (2) with a screwable cap (7) for filling air bubbles (4) to make up for total pressure in the tyre initially as well as in case of reduction in pressure as and when caused by puncture. 3. A puntureless tyre/tube as claimed in claim 1 wherein the said light plastic /rubber (3) material is provided to give optimum strength, flexibility, temperature bearing capacity, size, weight and stuffing of the above said air capsules /bubbles (4). 4. A punctureless tyre /tube substantially as herein described and illustrated with reference to the accompanying drawing (Fig. 1 & Fig. 2) |
