Patent ID: 8454336

Claim:
A vulcanizing mold for a tire, the tire having a general toric shape, substantially symmetrical about an axis comprising: a frame; two lateral shells offset axially relative to each other and mounted so as to be capable of axial translational movement with respect to the frame; a plurality of segments distributed circumferentially at the edge of the shells and arranged axially between the two shells, the segments being mounted so as to be capable of radial translational movement with respect to the shells; means for coupling the segments to one of the two shells, called the driving shell, comprising a lever, means for linking the lever to the segment which comprise a pivot link with an axle orthogonal to the axial and radial directions defined by the mold, means for linking the lever to the driving shell which comprise a pivot link with an axle orthogonal to the axial and radial directions defined by the mold; guide means for the axle of the means for linking the lever to the driving shell; and the coupling means and the guide means being arranged such that the axial displacement of the driving shell with respect to the frame causes a displacement of the axle of the means for linking the lever to the segment which is substantially exclusively radial with respect to the driving shell.
