NONCONTINUOUS PNEUMATIC VEHICULAR INNERTUBE

摘要

The invention is an inflatable pneumatic innertube which is able to be placed on or taken off the wheel rim of a vehicle without removing the rim from the vehicle. The innertube is of a non-continuous form, that is, it has two sealed ends, either of which can be threaded around or through the structural components of the vehicle which hold the rim in place and thus be in a position to be placed on the rim. After the threading, the two sealed ends may be held together by a mechanical holding device or system so that the innertube may be placed on the rim and in the outer tire by well known procedures. The mechanical holding device or system serves to cause the two sealed ends to bear one upon the other when the tube is inflated and thus eliminates any loss of the cushioning effect of the innertube.
