Invention Purpose: Eliminate Flats
During for example Motocross it's sometimes preferable to have a lower pressure in the MC-tires than what is recommended for normal road usage. With a low pressure in the MC-tire the MC-tire and the tube becomes vulnerable to impacts and other kinds of damage. The low pressure causes the MC-tire to skid on the rim, it might also cause the MC-tire to come off the rim. Furthermore the low pressure can cause the tube to get squeezed between the MC-tire and the rim edge. This causes a puncture to the tube and might make the MC-tire come off the rim. In racing it's obviously preferable to be able to finish the race even after pressure is lost in the MC-tire, this would be possible if there was a device which fitted the tire against the rim even without pressure in the MC-tire.
The Solution: T-Lock Concept
T-Lock Concept is a rubber device which replaces the tube inside the wheel. T-Lock Concept consists of a rubber device (T-Lock), tube, sealing fluid, and a needle-valve. T-Lock is mounted together with the tube as a single unit into the rim ditch. Afterwards the tire is mounted onto the rim with sealing fluid inside.The T-Lock tube is pressurized which causes T-Lock to squeeze the MC-tire beads towards the inside of the rim edges. T-Lock's sealing lips will seal the area between the MC-tire and T-Lock. The needle-valve is inserted through the MC-tire and then the MC-tire is pressurized through the needle-valve. The needle is then removed from the MC-tire and the sealing fluid will seal the hole caused by it.
T-Lock has 3 sealing lips on each side, the function of these is to prevent air from leaking out. It's important that these are both intact and clean (be cautious when you are using tire leavers during the assembly of T-Lock).
To create a high level of friction between the MC-tire and the rim so that the MC-tire does not skid against the rim. For this reason it is very important that the MC-tire beads and the rim edges are both clean and dry.
It is important that the inside of the MC-tire is intact and clean, therefor you should not use a MC-tire which has previously been used with a traditional rim-lock and tube setup.
T-Lock seal seals the hole created by the needle-valve and helps the T-Lock sealing lips to seal against the inside of the MC-tire. The fluid also prevents air from leaking out through the MC-tire. MC-tires aren't made to be completely air-tight as they are made to be mounted together with a tube. T-Lock seal can even seal up minor damages to the MC-tire which can happen during driving. It is also important to mount the caps over the hole(s) in the rim after the old rim lock etc. If this would not be done the T-Lock tube would expand outwards through the hole(s) due to the high pressure which would cause a puncture to the T-Lock tube.
