Definitions

  • the invention relates to a torsion band door arrester for motor vehicle doors, consisting of a door bracket which is pivotably pivoted about an axis which is at least approximately parallel to the door hinge axis, and a holder housing which is penetrated by the door retaining rod and is fastened to the other door arrangement part by means of a bearing block on a door arrangement part, door or door spar.
  • the braking or. Holding force of the door arrester effecting spring load either by pressure springs, which are accommodated in the holder housing and act directly on the brake body interacting with the door retaining rod, which naturally entails a relatively high production outlay for the door arrester, even if one of the two brake bodies interacting with the door retaining rod is arranged in a fixed manner and only the second brake body cooperating with the door holding rod is subjected to the load of a compression spring supported against the holder housing.
  • the invention has for its object to improve a door lock of the type mentioned in such a way that it has the advantages of a small-sized door lock of the first type and the advantage of a high braking and holding force, as they is characteristic of a door arrester equipped with a torsion bar spring, is unified in itself and can be produced with substantially less effort compared to both known types with at least the same maintenance freedom and long service life.
  • the door holding rod is designed as a torsion band and on the one hand is supported against tilting with respect to its torsion axis in the bearing block forming its pivot bearing and on the other hand is guided in the holder housing between two relentlessly mounted brake bodies.
  • the use of the door holding rod as a torsion band enables an optimally simple construction of the door arrester in particular if the door holding rod is designed as a door holding band, preferably made of a flat material blank and twistable around or parallel to its longitudinal axis.
  • the holder housing has a very high braking or. Holding force of the door arrester reached.
  • the design of the brake body as rollers or needles made of a wear-resistant material also allows for a silent or at least very quiet movement of the door arrester with the simplest design of the storage of the brake body, which not least results from the fact that neither the holder housing nor the brake body stored therein has the torsional resistance the door support bar can yield.
  • the invention can be implemented in a variety of configurations, with regard to The formation of the door support bar forming the torsion band is seen as a first embodiment in that the door support bar consists of a simple or folded flat material blank and is provided at least on one side with an edge embossing directed transversely to its plane of movement, for example in such a way that the door support bar has its longitudinal center starting from its ramps, which are designed to rise upwards along a longitudinal edge, and formations forming locking marks enclosed by them.
  • the door holding rod consists of a simple or folded flat material blank and is provided with moldings which are designed to rise from their one longitudinal edge to their other longitudinal edge and form brake ramps and locking marks enclosed by them.
  • the door retaining bar which consists of a flat material blank, is provided on at least one of its longitudinal edges with an edge bead projecting on one side with respect to its plane of movement.
  • the two longitudinal beads are each directed opposite to each other, i.e. that, based on the width of the door handle bar, the longitudinal bead arranged on its one long side points downward and the longitudinal bead arranged on its other long side points upward.
  • the door holding rod formed from a flat material blank with its end having an articulated eye is received between the two arms of a two-armed bearing block in such a way that the torque resulting from the torsional load on the door holding rod is supported directly against the arms of the bearing block.
  • the door support rod can be mounted on the rivet bolt with a ring of bearing material for the purpose of largely reducing metallic friction, if necessary by lining the inner circumference of its articulation eye.
  • the door holding rod is connected to a solid bearing sleeve by means of a positive engagement by means of positive engagement and the bearing sleeve in turn is mounted on the two-armed bearing block by means of a bearing pin which passes through it, in particular in the form of a rivet bolt.
  • the door holding rod can be made by means of a circumferential groove in the bearing sleeve and off-center to its length, e.g. be connected in the lower third, so that there is a certain amount of design freedom with regard to the design or adaptation of the articulation of the door support rod.
  • a further, in particular mechanically producible, design of the pivot bearing of the door holding rod is characterized in that the bearing sleeve supporting or supporting the door holding rod on the bearing pin of the two-armed bearing block is formed by a compression bushing, the compression bushing, on the one hand, rests against the door support rod without play via two compression collars, and on the other hand over each end collar on each of the two arms of the bearing block.
  • the holder housing is formed by a block of material provided with through holes for fastening screws
  • the block of material forming the holder housing is advantageously formed in one piece as an injection molded part, in particular from a plastic material.
  • grooves or the like which are open to the outside are expediently provided, into which the rollers forming the brake body can be inserted and fixed by subsequent caulking of the groove edges.
  • the fastening thereof can also be provided by means of a sheet metal frame, in which case the sheet metal frame with an upper rim overlaps the edge regions of the material block and is fastened to the door arrangement part via lower laterally projecting tabs and screw bolts or the like is.
  • the holder housing can also be designed in two parts, in particular divided parallel to the passage plane of the door holding rod, in which case the two housing parts can likewise consist of injection molded parts, in particular of a plastic material.
  • the holder housing is designed as a two-part sheet metal housing consisting of a flat pot part and a flat cover part.
  • the door arrester for motor vehicle doors shown in the drawing consists of a bearing bracket 1 on one door arrangement part, here door spar 2 about a door holding rod 6 pivotably articulated about an axis 5 which is at least approximately parallel to the door hinge axis 3 of the door 4, and a door holding rod 6 penetrated by the door holding rod 6 on the other door arrangement part , here the door pillar 2, struck holder housing 8.
  • the door holding rod 6 is designed as a door holding band, preferably from a flat material blank.
  • the brake bodies 9 mounted in the holder housing 8 are formed by rolling needles made of a wear-resistant material and are each rotatable about fixed axes.
  • the door holding rod 6 consists of a flat material blank and is provided with moldings which are designed to rise from their one longitudinal edge 10 starting from their other longitudinal edge 11 and form braking ramps 12 between them, as shown in the illustration in FIG. 7.
  • the holder housing 8 is provided with a through-hole 14 for fastening screws, in particular with an injection molded part, e.g. formed from a plastic material, one-piece material block shown and the rollers forming the brake body 9 are arranged in corresponding recesses 15.
  • an injection molded part e.g. formed from a plastic material, one-piece material block shown and the rollers forming the brake body 9 are arranged in corresponding recesses 15.
  • the holder housing 8 is fastened to the vehicle door by means of a sheet metal frame 16 instead of via a direct screw fastening, the sheet metal frame 16 having an upper rim 18 engaging over the edge areas of the material block and is attached to the door via lower laterally projecting tabs 19 and bolts or the like.
  • the holder housing 8 is designed in two parts, in particular divided parallel to the passage plane of the door support rod 6, the two housing parts 20 and 21 made of injection molded parts, in particular made of a plastic material, and are provided with through holes 22 for fastening screws.
  • the holder housing 8 of the door arrester shown in the embodiment according to FIG. 6 is designed as a two-part sheet metal housing consisting of a flat pot part 23 and a flat cover part 24, the brake bodies 9 formed by steel needles being supported against the inner surfaces of the pot part 23.
  • the door holding rod 6 formed from a flat material blank is received with its end having a pivoting eye 25 between the two arms 26 and 27 of a two-armed bearing block 1 in such a way that the moment resulting from the torsional load on the door holding rod 6 is supported directly against the arms 26 and 27 of the bearing block 1.
  • the door holding rod 6 is supported by means of a rivet bolt which passes through the two arms 26 and 27 of the bearing block 1.
  • the door holding rod 6 is mounted on the rivet bolt 29 with a ring 28 made of bearing material for the purpose of substantially reducing metallic friction in the pivot bearing 1 while lining the inner circumference of its pivot eye 25.
  • the door holding rod 6 is connected in a tilt-proof manner to a solid bearing sleeve 30 via its articulated bore 25 by means of a positive engagement, and the bearing sleeve 30 is in turn mounted on the two-armed bearing block 1 by means of a bearing pin which passes through it and is designed as a rivet bolt 29 the door holding rod 6 engages in a circumferential groove of the bearing sleeve 30 and overall eccentrically to its length, in the lower third of which is connected to the bearing sleeve 30.
