Stop device, in particular for an automotive vehicle door

Claim 1

In a stop device for a pivotal door, said device comprising an arm for pivotally mounting on a first element of two elements consisting of a door and a fixed post on which the door is pivotally mounted, a bracket for fixing on a second element of said elements, a first roller structure and a second roller structure, journal means respectively rotatively mounting both the roller structures on the bracket, said arm having a shape of a strip and defining two opposed edges against which edges are applied said two roller structures, said first roller structure being fixed in position and said second roller structure being movable relative to said bracket, means for elastically yieldably biasing the movable roller structure against said arm so as to create a contact under pressure between each of the two roller structures and said arm, said arm defining a stop notch for retaining the fixed roller structure in an open position of the door; the improvement in which each roller structure comprises an inner cylindrical ring and an outer cylindrical ring, the inner cylindrical ring being rotatively mounted inside the outer cylindrical ring and on said journal means therefor, each ring having at an end of said each ring an outer cylindrical surface and including a planar radially outwardly extending flange, the flange of the inner ring having such radial dimension that it projects radially beyond said outer cylindrical surface of the outer ring so that a sliding contact can occur radially between the two rings and also axially between the flanges and respective outer faces of the arm.
