Definitions

  • the subject of the present invention is a stop device, in particular for a pivoting door of a motor vehicle, comprising an arm intended to be pivotally mounted on one of the parts constituted by the door and by the fixed upright on which the door is mounted, this arm having the shape of a blade, in contact with the two opposite edges of which are applied two rollers, one of which is fixed and the other of which, mobile, is subjected to an elastic action which creates a contact pressure between each of the two rollers and the arm, the latter being provided with a catch for retaining the fixed roller in the open position of the door.
  • rollers used are solid rollers which, being subject to wear which is all the less avoidable as they are not protected from dust and weathering, require a periodic lubrication, failing which the stop device would become inoperative after a relatively short time.
  • the object of the invention is therefore to provide a door stop device which can have a long service life without lubrication being necessary.
  • each roller consists of two cylindrical rings nested one inside the other, which each have at one of their ends a flat collar oriented radially towards the outer, the flange of the inner ring having a radial dimension such that it protrudes from the cylindrical surface of the outer ring and that thus a sliding contact can be established, not only radially between the two rings, but also axially between the flanges and the respective external faces of the arm.
  • the two rings are advantageously provided with a surface coating in a sliding varnish, made of a material with a low coefficient of friction, such as polytetrafluoroethylene.
  • the invention is shown in its application to a vehicle door, but it is obvious that the stop device can be used for other pivoting closing members of the vehicle, such as the engine hood, the trunk, tailgate or the like, or even in other types of device, for example for covers for household appliances, suitcases, chests and the like.
  • the term "door” is used here in a very broad sense to designate these various pivoting closing members.
  • FIG. 1 represents a bodywork upright 1 on which the left front door 3 is articulated by means of hinges whose axis 2 passes through two knuckles 5, fixed respectively on the upright 1 and on the door 3.
  • the latter is retained in the open position by a stop device which comprises an arm-4 in the form of a flat blade, one end of which is provided with a hole 6 through which is engaged an articulation axis 7, parallel to the axis 2 and integral with a yoke 8 fixed to the door 3.
  • the arm 4 has on its front edge 4a a catch 9 in which can be engaged, in the end of opening position , a roller 12 carried by a fitting 14 secured by means of bolts 16 with one of the sheet metal parts constituting the upright 1 through which the arm 4 passes.
  • the front edge 4a of the arm 4 is pressed against the roller 12, which is fixed, by an opposing roller 13, also carried by the fitting 14 and biased by an elastic torque at rear edge contact 4b of arm 4.
  • the fitting 14 is in the general form of a plate defined by two large flat wings 17, whose shape is approximately that of a quadrilateral, which are applied to the sheet la and are perforated at 17a to allow the passage of the fixing bolts 16.
  • the two wings 17 extend symmetrically on either side of a central portion 15 in the shape of a U, obtained by folding, the two flat branches 18 of which are perpendicular to the wings and uniformly spaced from the plane of symmetry XX, are used for mounting two axes 19, 21, one of which rotatably supports the roller fixed 12 and the other of which greatly exceeds the branches of the U 15 by forming two extensions 27 which extend in line with the respective wings 17 and around each of which is engaged a helical winding 28, the free end of which is anchored in contact with a square edge 29 of the corresponding wing 17, and which is part of a torsion spring 31, the central part of which forms a stirrup 32 connecting, by the transverse element 30, the adjacent ends of the two windings .
  • the crosspiece 26 of the central portion 15 in the shape of a U is approximately perpendicular to the wings 17 and is located in a marginal position relative to them, so that the arm 4 can move between the branches 18 without there being interference with the cross member 26 from which it is constantly spaced.
  • each of the rollers 12, 13 consists of two cylindrical rings 46, 47, of treated steel, which each have at one of their ends a flat collar 56, 57 oriented radially outwards, and which are fitted one inside the other.
  • the radial dimension of the flange 56 of the inner ring 46 is such that it projects from the cylin surface drique of the outer ring 47.
  • the two rings therefore have a sliding contact, radially, between their adjacent cylindrical surfaces and can, if necessary, also have an axially sliding contact, between the non-flanged end of the outer ring 47 and the collar 56 of the internal ring.
  • a coating 58 of polytetrafluoroethylene, or of another material with a low coefficient of friction, is applied superficially on the two rings 46, 47, to improve the sliding characteristics, not only between the two rings, but also between the internal ring 46 and the axis 19, or the element 30, and between the flanges 56, 57 and, on the one hand, the internal faces 18a, 18b of the branches 18 of the fitting 14, on the other hand, the lateral faces 4c, 4d of the articulated arm 4.
  • the two rollers 12 and 13 are applied under pressure in contact with the edges 4a, 4b of the arm 4.
  • the two rollers are supported on a straight part of the edges 4a, 4b, so that the torque to be exerted to open the door is very low.
  • the rollers 12, 13 must respectively cross the angular profile boss 10 formed on the edge 4a and the zone 11 with convex curvature of the edge 4b, before the roller 12 finally falls into the notch stop 9 which retains it positively, by its end flank 9a, as shown in FIG. 1.
  • rollers 12, 13, with double ring 46, 47 have been shown and described as parts of the particular example of door stop device, which is the subject from application FR 80 05870. It goes without saying that these double ring rollers can be used in any door stop device comprising an articulated arm, on the edges of which two opposing rollers are applied, in which case the internal faces of the flanges 56, 57 have with the lateral faces of the arm a sliding contact with reduced friction, because the flanges undergo a rotational movement under the effect of the movement of the arm.
  • each roller is mounted between two parallel flat surfaces, against which the external faces of the flanges 56, 57 have a sliding contact.
  • the rollers according to the invention can be applied to the door stop device described in patent FR 78 29777.
