<p>The invention refers to an emergency device (4) connectable to a wheel of a land vehicle equipped with an inflatable tire, for the purpose of allowing the circulation of the vehicle when the tire is deflated. The device, object of the invention, comprises a ring (19) having an external diameter equal to the diameter of the tread of the tire, and connected, by means of plates (6) arranged radially, to a pair of curved elements (7, 8), each having an interspace at its convex edge in which a circular edge projecting from the rim of the wheel is partially housable. The two curved elements are mutually facing at the concavity and are mutually connected at a first respective end in a manner such that they can rotate with respect to each other. At a second end opposite said first end, one of the two curved elements is connected to a nut, the other curved element is connected to a stop. A screw is screwed in the nut to the point where it exerts a thrust on the stop tending to mutually move away said second ends. This places the curved elements in abutment against the rim of the wheel while the projecting edge of the latter is housed in the interspaces of the curved elements. In such a manner, the device that is the object of the invention is integrally associated with the rim of the wheel.</p> |
