Definitions

  • the invention relates to a door arrester for motor vehicle doors, consisting of a pivotally attached door support rod with at least one double-sided thickening and a two cylindrical roller rolling elements rolling on the two broad sides of the door support rod, which are penetrated by the door support rod and attached to the door, in which the brake roller bodies are mounted so as to be movable against a spring load essentially transversely to the plane of movement of the door holding rod, the brake roller bodies being accommodated in cage-like holders in recesses aligned parallel to the plane of movement of the door holder rod such that they extend over the recesses of the recesses in the region of their overlap with the door holder rod push through in the holders and only at their end regions lying outside in relation to the door holding rod over the major part of their circumference in the recesses the cage-like holders are rotatably mounted and the cage-like holders are supported by spring-elastic means against the wall surfaces inclined to the plane of movement of the door holding rod or the cover surfaces of the holder housing.
  • Such door locks for motor vehicle doors are known from DE-PS 27 02 731 and the associated DE-PS 29 44 766.
  • the brake rolling elements are formed by cylindrical rollers with end faces oriented essentially perpendicular to their axes and are furthermore the sections of the recesses in the holders forming the bearing of the brake rolling elements are open towards the two end faces of the holder and are designed such that they encompass the brake rolling elements to the majority of their circumference in order to enable automatic pre-assembly of the brake rolling elements in the holders.
  • the invention is therefore based on the object of further improving a door arrester of the type described at the outset in such a way that, despite automatic pre-assembly of the brake roller bodies designed as cylinder bodies, chafing of the brake roller bodies on the side walls of the holder housing is excluded, as is deposition of abrasion and dirt in the bearings the brake roller inside the holder.
  • This arrangement also ensures, in conjunction with an automatic pre-assembly of the brake roller bodies, the possibility of designing the bearings of the brake roller bodies in the holders in such a way that deposition of abrasion or dirt and the like is completely ruled out in the area of the bearing surfaces of the brake roller bodies and the door stop therefore overall has a higher fatigue strength.
  • the restraining means are formed by projections or noses which protrude inwards with respect to the recesses receiving the brake roller bodies and are arranged radially to the recess sections in the holders supporting the brake roller bodies.
  • the too the recesses which receive the brake roller bodies and which protrude radially inwards or Lugs are expediently arranged on the outside in relation to the bearings of the brake rolling elements.
  • the arrangement and design of the projections or lugs with the advantage of a certain transverse elasticity of the holder as a whole is expediently made such that the radially inwardly projecting projections or lugs with the wall parts of the holder that overlap the end faces of the brake rolling elements each have a frustoconical partial annular space lock in.
  • the recess sections forming the bearing for the brake rolling elements in the holders are extended to the side thereof directed towards the door holding rod and that the projections or noses projecting radially inwards and arranged in connection with the bearing surfaces for the brake rolling elements a radially to this directed distance to the intended operating position of the axes of rotation of the brake rolling elements are arranged on the holder.
  • the door arrester shown in the exemplary embodiment essentially consists of a door support rod 1 which is attached to a door pillar (also not shown) and which is provided with a double-sided bulge 2 via a pivot bearing (not shown in detail) about an axis parallel to the hinge axis of the door.
  • the door holding rod 1 passes through a holder housing which is fixed to the front wall of a vehicle door (not shown in detail) and is generally designated by 3 and consists of a pot-shaped housing body 4 and a cover 5 which closes the open side thereof.
  • the cover 5 is fastened to the housing body 4 by means of folded flaps 8 and is provided with a slot recess 9 which, in conjunction with a slot recess 10 in the holder housing base 11 of the door holding rod, enables passage through the holder housing.
  • brake roller bodies formed by cylindrical rollers 12 made of hardened steel are arranged in the holder housing 3 and are rotatably supported in cage-shaped holders 13.
  • the holders 13 are designed as sliding blocks and are slidably supported on the side walls of the holder housing 4 in such a way that they can perform a sliding movement directed at an angle to the plane of movement of the door holding rod 1, which causes the brake rolling elements 12 to be adjusted essentially perpendicular to the door holding rod.
  • the front ends 14 of the rollers forming the brake rolling elements 12 are spherical and of one piece with the body formed side walls 15 of the holder 13 overlapped.
  • the side walls 15 of the holders 13 have on their inner surface 16 a bulge directed outwards towards the side walls 4 of the holder housing, the radius of curvature of which is greater than the radius of curvature of the spherical ends 14 of the brake roller bodies 12.
  • the brake roller bodies 12 are rotatably supported in the holders 13 via bearings 17, the bearings having only a maximum of half the circumference of the brake roller bodies encompassing bearing surfaces 18 and basically recesses in the holders 13 which are approximately V-shaped and open towards the door holding rod 1.
  • projections or noses 19 projecting radially inwards on the holders 13 on both sides and with respect to the bearings 17 are formed on the outside.
  • the projections or lugs 19 are arranged in such a way that they allow the brake roller bodies 12 to move parallel to the intended operating position of the axes of rotation of the brake roller bodies and perpendicular to the bearing surfaces.
  • the projections or lugs 19 are essentially wedge-shaped, such that they each form an essentially frustoconical partial annular space 20 with the inner surfaces of the side walls 15 of the holders.
