Abstract
The present invention provides an accessory for a flap for use with an inner tube and wheel, comprising a base of oblong shape whose upper face is provided with a rigid insert in the form of a hollow cylinder, said accessory being made by molding a single material that resists creep up to a temperature of 180° C., to prevent the flap creeping through an orifice in the wheel.
Claims6
An accessory for a flap, said flap positionable between an inner tube of a pneumatic tire and a mounting rim for said pneumatic tire, said rim having a valve passage orifice, and said flap having a cylindrical valve passage orifice, said accessory being a molded element made from a single moldable material which resists creep up to a temperature of 180 degrees C., having a base of essentially oblong shape, wherein a face of said base for contacting said flap has a rigid insert having the shape of a hollow cylinder projecting from said face of said base, said base being provided with an orifice at the end of the insert to allow the passage of an inflation valve stem through the insert, wherein said base is sufficiently large so as to cover said valve passage orifice on said rim to prevent the flap creeping through said orifice on said rim.
