1. In a stop device for combination with two parts which consist of a door post and a door mounted on the post to pivot about a pivot axis, the device comprising an arm for mounting on one of said parts to pivot about an axis parallel to said pivot axis and having two opposed edges, a bracket member for fixing to the other of said parts and comprising two parallel branches, two rollers mounted between the parallel branches of the bracket member, one of the rollers being fixed in translation relative to the bracket member and the other roller being movable in translation relative to the bracket member, a rocker, a pin pivotally mounting the rocker between the branches of the bracket member, the movable roller being mounted on the rocker, elastically yieldable means for subjecting the rocker to an elastic torque which creates a pressure of contact between each of the two rollers and the opposed edges of the arm, the arm defining a stop recess for receiving and retaining the fixed roller in the open position of the door:

  • the improvement wherein the branches of the bracket member are part of a U-section centre portion of the bracket member and two large wing portions extend symmetrically from each side of the centre portion in a direction perpendicular to the branches, said pin having two portions extending beyond the branches in the region of the wing portions, said elastically yieldable means comprising two helical windings which form a torsion spring and are respectively mounted on each of said two pin portions and have a first portion which bears against the corresponding wing portion which includes an abutment for said first portion, and a second portion which bears against the rocker, the U-section centre portion comprising a transverse portion which is located adjacent an edge of the wing portions and is substantially perpendicular to the wing portions so that the pivotal arm engaged between the two rollers can move while remaining spaced away from said transverse portion of the U-section centre portion.
