Stop device for a pivotal door, in particular for an automobile vehicle door
First Claim
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.

Abstract
Pivotally mounted on the door is an arm which has a stop recess in which there may be retained a fixed roller which is mounted in a bracket member fixed to the fixed post of the door. The arm is applied against the roller under the effect of a movable roller which is mounted on the bracket member and is biased into contact with the arm by a torsion spring which has two windings which are disposed symmetrically on each side of branches of the bracket member.

- 15. A stop device for a pivotal door, comprising an arm adapted to be pivotally mounted, by means of a pin parallel to the pivot pin of the door, on one of two parts consisting of the door and the fixed post on which the door is mounted, said arm having the shape of a strip having opposed edges against which edges are applied two rollers which are mounted between parallel branches of a bracket member which is adapted to be fixed to the other part of said two parts, one of the rollers being fixed and the other roller being movable and subjected to an elastically yieldable torque which creates a pressure of contact between each of the two rollers and the arm, the arm being provided with a stop recess for retaining the fixed roller in the open position of the door, the elastically yieldable torque being produced by a torsion spring comprising a centre stirrup portion interconnecting adjacent ends of two helical windings which are mounted symmetrically on each side of the branches of the bracket member about extensions of a pin which extends through the branches of the bracket member, which branches are part of a U-sectioned centre portion of the bracket member on each side of which centre portion are symmetrically formed two large wing portions which are perpendicular to the branches and have two spaced-apart abutments against which abutments bear ends of the respective windings opposed to the branches, the U having a transverse portion which is roughly perpendicular to the wing portions so that the pivotal arm engaged between the rollers is capable of moving while remaining spaced away from the transverse portion of the U, wherein the movable roller is rotatively mounted on a transverse portion of the centre stirrup portion of the torsion spring so that it is directly subjected to the elastically yieldable torque.
