Definitions

  • the invention relates to a method for producing a door support rod for such motor vehicle door locks, in which a formed from a flat material blank and on a door arrangement part, door or door pillar, pivoted about an axis parallel to the door hinge axis, door support rod protruding transversely to its plane of movement or the like. interacts with brake or holding bodies accommodated in a holder housing which is fixedly arranged on the other door arrangement part.
  • door holding bars for use in connection with door stays of the aforementioned type, a large number of designs of door holding bars, in particular multi-part door bars or formed from a folded flat material blank, are known.
  • an area of the flat material blank that is at least partially cut free in the central region of the width of the flat material blank forming the door holding rod is pushed through to one side or the other to such an extent that the required height the locking or braking ramps results, which in the case of the construction mentioned corresponds at least to the amount of the material thickness of the flat material blank.
  • this known design of the door holding rod has the disadvantage that the cut out of the flat material blank and its plane compared to bent areas have no support against the adjacent areas of the door holding rod at least in the area of the largest elevation of the locking or braking ramps and therefore during the passage between the Brake bodies of the holder housing are resiliently deformed by their contact pressure and thereby lose their actual contour more or less, so that the precision with which the door is braked or locked is more or less lost and the door is rather braked or held at a point in its opening angle that cannot be precisely determined, which is what With regard to the mostly substantial length of the doors, in particular two-door vehicles, can certainly lead to difficulties, for example because the door strikes the garage wall in narrow garages.
  • the locking or braking ramps of the door holding rod formed from a flat material blank are formed by correspondingly embossing the flat material blank on one side, the locking or. Brake ramps are cut-free connected to the adjacent areas of the flat material blank forming the door holding rod.
  • Brake ramps of the door support rod is significantly smaller than the material thickness of the starting flat material blank.
  • Such low heights of the latching or braking ramps are, however, not usable in most cases, since they make the manufacture of the door arrester more expensive, on the one hand, and make them heavily worn, on account of the high contact pressure of the latching or braking bodies interacting with them, and thus particularly in the case of heavy vehicle doors.
  • a door support rod which is intended for those motor vehicle door arresters in which a door support rod formed from a flat material blank and on one door arrangement part, door or door pillar is pivoted about an axis parallel to the hinge axis projecting ramps protruding transversely to their plane of movement with one another Bracket or holding bodies arranged in a stationary manner in the door arrangement part of the housing housing cooperates, the latching or braking ramps extending over a central region of the door holding rod being formed on one side on a door holding rod made of a flat flat material blank and having a maximum height that corresponds at least approximately to their full material thickness.
  • the latching or braking ramp is also pressed out of a flat material blank by stamping in a special operation in this door holding bar, which initially does not guarantee any security against resiliently deforming the latching or braking ramps when the door holding bar passes through the holder housing and furthermore the use of a sufficiently thick one Starting material required.
  • the invention is therefore based on the object of demonstrating a method for producing a door holding rod provided with braking ramps or locking ramps for a door arrester of the type mentioned at the beginning from a one-piece flat material blank of conventional material quality, by means of which the door holding rod, on the one hand, with a minimum of effort, a sufficient, in particular at least approximately height corresponding to the material thickness of a starting flat material blank, latching or.
  • Brake ramps can be equipped and on the other hand receives sufficient strength to avoid an undesired deformation of the locking or braking ramps when the door holding rod passes through the holder housing.
  • the door holding rod is formed without cutting from a flat sheet material blank by extrusion, the locking or braking ramps extending only over a central region of the broad side of the door holding rod and being removed from the flat sheet material blank on one side in this way, that they have a maximum height corresponding at least approximately to the full material thickness of the starting material.
  • the manufacturing method according to the invention leads to a door holding rod designed as an extruded part and ensures, on the one hand, that the door holding rod can be manufactured easily and, on the other hand, that the latching or braking ramps are formed with the surrounding surface areas of the flat material blank forming the starting material and, at the same time, also provides permanent support the same against the base of the door holding rod, so that even with a maximum height of the latching or braking ramps corresponding to at least approximately the full material thickness of the starting flat material, springing of the same is excluded when passing through the holder housing.
  • the method there is a simple but effective stabilization of the latching or. Braking ramps in that the transitions between the lower region of the formed latching or braking ramps and the adjoining flat regions of the flat material blank forming the door holding rod are shaped radially on both the top and the bottom.
  • a particularly simple and therefore preferred embodiment of the method therefore provides that the starting flat material blank is deformed into an essentially U-shaped profile cross-sectional shape, the outer circumference of the profile cross section being given essentially rectangular boundary edges and the inner circumference of the profile section being trough-shaped essential arcuate boundary edges is provided.
  • a particularly effective support or stabilization of the latching or braking ramps can be achieved in a further embodiment of the method in that the latching or braking ramps are shaped with their lower edges in line with the inner upper edges of the flat areas of the flat material blank forming the door holding rod and at intervals are provided via webs which are directed essentially transversely to the longitudinal extent of the latching or braking ramps, which are designed by forming internal transition radii and supporting the latching or. Form braking ramps against the flat areas of the door support bar.
  • the material required for the formation of the webs is used in the formation of the locking or.
  • Brake ramps of the door holding rod are displaced from the areas of the linear arrangement of the latching or braking ramps on the flat areas of the door holding bar.
  • the door support rod is deformed in the region of its articulation end at the same time as a pivot eye angled at right angles to its passage plane through the holder housing.
  • Brake ramps 1 and 2 provided door holding rod 3 is made by extrusion in one operation from a flat sheet material blank.
  • the rest or Brake ramps 1 and 2 are arranged in the longitudinal center of the flat material blank forming the door holding rod 3 and only occupy the central area thereof, such that on both sides of the locking or braking ramps 1 and 2 there are respectively flat adjacent and smooth surface areas 4 and 5 of the initial flat material blank .
  • the shape of the locking or. Brake ramps 1 and 2 are designed in accordance with FIG.
  • Brake ramps 1 and 2 along their two long sides 6 and 7 remain connected to the smooth-surface areas 4 and 5 of the starting flat material blank via transitional bridges 8 and 9.
  • the transition webs 8 and 9 are connected by radially shaped transitions 11 and 12 to the inner surfaces 13 and 14 and likewise by radially shaped transitions 15 and 16 to the outer surfaces 17 and 18 of the smooth-surface areas 4 and 5 of the starting flat material blank.
  • the door holding rod 30 is likewise formed by an extruded part and the latching or.
  • Brake ramps 10 and 20 are also arranged in the longitudinal center of the door holding rod 30.
  • the braking ramp 20 which extends over a greater length of the door holding rod 30, however, a different design is shown here, in that the underside 21 of the braking ramp 20 is only connected linearly to the adjacent smooth-surface areas 40 and 50 via short sections 22, the transitions 120 forming a right angle or being equipped with a small radius that cannot be represented in the drawing.
  • the braking ramp 20 is connected to the adjacent smooth-surface areas 40 and 50 by means of webs 23 which are directed essentially transversely to their longitudinal extent, the webs 23 being at least on the inside in a radius 110 or 112 into the inner surfaces 130 and 140 of the exit Pass over flat material cut such that the inner cross-sectional profile has a rounded U-shape.
  • the outer surfaces 170 and 180 of the smooth-surface areas 40 and 50 are adjoined by the side surfaces of the braking ramp 20 which are perpendicular to these, at right angles or with a small radius which cannot be represented in the drawing.
  • the door holding rod 3 or 30 is provided with a bearing eye 31 which is angled perpendicular to its general plane.
