JPH1067206A - Emergency relief tire tube - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an emergency relief tire tube which is incorporated in the tire of an autobicycle or the like as a spare in such a way as it is immediately replaced and used when the standard tire tube is punctured. SOLUTION: A relief tire tube is disposed in a non-expanded state between a tire rim 4 and the standard tire tube. The relief tire tube has an expansive portion which is so formed as to be connected and holded at its both end parts. A relief tire tube air entrance valve 1 is installed on the tire rim 4 in order to easily fit the relief tire tube in a tire 7. The unexpansive portion is mounted adjacent to or passing through the standard tire tube. An foot-operated pump or other optional similar device injects air into the relief tire tube to expand it for pushing away the punctured and contracted standard tire tube.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the field of emergency relief tire tubes used in motorcycle tires and scooter tires.

[0002]

Although motorcycle tire tubes have been in use for many years, emergency relief tire tubes mounted on automated vehicle tires are not yet known. If a currently existing type of tire or its inner tube has punctured, and if you do not have spare wheels, there is no other option than to go to the nearest tire garage for repair. It is very rare for motorcycle riders to carry spare wheels and that is not a practical solution.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an emergency relief tire tube for a punctured tire. Motorcyclists can continue their journey further after pumping the relief tire tubes without significant delay, rather than going to an immediate repair shop, which is probably not nearby.

[0004] This immediate first aid is achieved by placing a spare emergency relief tire tube inside the motorcycle tire for immediate use during a puncture. The tire is reinflated by pumping air into the relief tire tube and displacing the contracted standard tire tube.

[0005] In order that the present invention may be more readily understood, the following description is provided by way of example only with respect to one particular embodiment of an emergency relief motorcycle tire tube made in accordance with the present invention.

Reference is made to the accompanying drawings.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS Briefly summarized, an embodiment of the emergency relief tire tube of the present invention is described as follows.

FIG. 1 is a side view of a motorcycle wheel provided with an emergency relief tire tube air inlet valve 1 and a standard tire tube air inlet valve 2 arranged opposite each other. It is necessary to provide holes 3 in the tire rim 4 for the auxiliary air valve.

In normal use, as shown in FIG. 3, a standard (in other words, normal) tire tube 5
Is inflated, while the leaf tire tube 6 is not inflated.

FIG. 2 shows the position of the standard tire tube 5 after the relief tire tube 6 has been inflated.

The cross section of FIG. 4 shows an embodiment of the motorcycle tire 7 in normal use. An inflated standard tire tube 5 is fitted (mounted) in the motorcycle tire 7, and a relief tire tube 6 is provided between the tire rim 4 and the standard tire tube 5 in the area of the relief tire tube air inlet valve 1. It is arranged in a non-inflated state.

As shown in FIG. 5, the area of the air inlet valve 2 of the standard tire tube 5 is
3 shows a non-expandable portion (a portion that is not an expandable portion, that is, a portion that is not expanded).

After puncturing, as shown in FIG. 6, the standard tire tube 5 contracts and the relief tire tube 6 is pumped with air to remove the motorcycle tire 7.
Occupy the inner part. This can be done by a portable foot pump or other similar device.

In the plan view of FIG. 7, the relief tire tube 6 is shown in an inflated state, the non-expandable portion 8 is shown in a crumpled state, and the standard tire tube 5 is shown in a contracted state.

FIG. 8 shows the normal position of the relief tire tube 6 together with the non-expandable portion 8. A rectangular hole 9 is provided so that the standard tire tube air inlet valve 2 penetrates the inflated standard tire tube 5.

A side view of the standard tire tube 5 and the relief tire tube 6 in the area of the standard tire tube air inlet valve 2 (shown in FIG. 9) shows that the relief tire tube 6 is 4 shows an embodiment that replaces a tire tube. The crumpled part, as shown in FIG. 9,
It belongs to the non-expandable portion 8 of the relief tire tube 6.

FIG. 10 illustrates the concept of the invention more clearly with a longitudinal section in the area of the standard tire tube inlet valve 2. The relief tire tube 6 occupies the inner part of the motorcycle tire 7, while the standard tire tube 5 has lost air and has contracted.

FIGS. 11, 12 and 13 show several examples of the method of forming the non-expandable portion 8 of the relief tire tube 6. FIG. FIG. 11 shows an example of using a specially formed one that is continuously formed so as to secure the connection between both ends 10 of the relief tire tube 6.

FIG. 12 is achieved by using a non-expandable piece of rubber or other material so that the ends 10 of the inflatable portion (ie, the inflatable portion) of the relief tire tube 6 are connected. This is another example of selection.

FIG. 13 shows another alternative achieved by fusing the relevant portion of the relief tire tube 6 to make it non-inflateable.

The embodiments described above do not limit the scope of the invention in any way, and the emergency relief tire tube can be used on any wheel to provide an emergency relief pneumatic effect.
