Definitions

  • the invention relates to a support rod mounting for motor vehicle door locks, consisting of a hinge eye bore in the door support rod of a door lock and a bearing block provided with at least one hinge eye bore, fixed to one of the two door arrangement parts, door or door pillar, and a bearing pin which, by means of a resilient support in one the hinge eye bores are mounted with a running seat and in which the door holding rod is supported resiliently and elastically against the bearing block in the axial direction of its mounting.
  • the invention has for its object to provide a support rod mounting for motor vehicle door locks, which on the one hand can be produced and assembled with the least possible effort and which on the other hand without permanent reduction of the strength of the bearing a permanently smooth and especially under attack from radial to the bearing axis directed force peaks guaranteed absolutely noiseless working storage of the door support rod of a motor vehicle door arrester.
  • the hinge eye bore in which the bearing pin has a seat has an excess compared to this and the bearing pin in this hinge eye bore is supported by a number of axially parallel leaf springs.
  • the bearing pin is expediently supported in the oversized hinge eye bore of the door holding rod and there at least one, but preferably three symmetrically arranged leaf springs, such that two adjacent leaf springs are on both sides of the longitudinal axis of the door holding rod.
  • the leaf springs supporting the bearing pin in the hinge eye bore are arched inwards transversely to the bore axis of the hinge eye bore, and furthermore radial groove recesses in the peripheral wall of the hinge eye bore, which are directed axially parallel to the bearing axis, are assigned to them, which on the one hand form a guide for the leaf springs, but this on the other hand when radial peaks occur
  • Loads of the storage also offer a sufficient alternative, such that the door support rod in its unloaded condition is supported or mounted in strips or lines by means of the leaf springs in a strip-like or line-shaped manner and compensates for play elsewhere, in particular, however, out of direct contact with it on the bearing pin, but the free rotation of the door holding rod compared to the hinge pin remains perfectly and smoothly.
  • the unloaded door support rod is also only supported by the leaf springs on the bearing pin, no noise can arise in the storage even when the door support rod is unloaded, even if the door hinge eye bore shows a certain amount of wear after a long period of operation.
  • the arrangement of the leaf springs is such that they lie outside those peripheral regions of the hinge eye bore which come into direct contact with the bearing pin when force peaks occur.
  • the arc height of the curvature of the leaf springs directed transversely to the bearing axis corresponds in the relaxed state to the sum of the depth of the groove recesses in the peripheral wall of the hinge eye bore and its oversize of the hinge eye bore of the door retaining rod compared to the bearing pin diameter.
  • the front edge of the leaf spring is fixed by cutting into the groove or by resting on the bearing block.
  • a particularly simple and therefore inexpensive method of manufacturing the leaf springs which at the same time ensures a particularly simple and time-saving assembly of the leaf springs, is characterized in that the leaf springs are formed in one piece with a holding plate which is essentially smooth and aligned parallel to the broad side of the door support rod, the leaf springs being cut free on one smooth surface spring steel sheet blank are formed.
  • the cutouts of the sheet metal blank that form the leaf springs can be provided in a first design within the area of the holding plate that overlaps with the hinge eye bore of the door holding rod, or in a second design also extend radially outward from the periphery of the holding plate in an approximately star shape.
  • the one-piece design of the leaf springs with the holding plate initially enables extremely simple manufacture and assembly of the bearing, since the leaf springs fixed in a predetermined position by the holding plate can simply be inserted into the hinge eye bore in the door holding rod.
  • the one-piece design of the leaf springs with the holding plate also enables, in a simple manner, the formation and assembly of a spring support of the door holding rod on the bearing bracket, which is directed in the direction of the bearing axis, in particular in that, in a first embodiment, the length of the leaf springs is approximately the same corresponds to the material thickness of the door holding rod and the leaf springs connect to the holding plate via a bend perpendicular to the plane of the broad side of the door holding rod and opposite to this, or that other bends are formed into the holding plate without leaf springs.
  • This bend of the leaf springs directed perpendicular to the broad side of the door holding rod forms a resilient support of the door holding rod directed in the direction of the bearing axis on the bearing block or on a head of the bearing pin, without additional parts or additional assembly processes being required for this.
  • this deflection of the leaf springs can be formed in one operation with the production of the holding plate formed in one piece with the leaf springs.
  • a resilient support of the door holding rod in the direction of the bearing axis can be achieved in a design in which the leaf springs are formed together with a holding plate by a star-shaped cut from spring steel sheet in that the free cuts forming the leaf springs are bent parallel to the holding plate and inward towards the hinge eye bore and are finally angled parallel to the hinge eye bore.
  • the Leaf springs are arched around axes parallel to the bearing axis and the radial groove recesses assigned to them in the peripheral wall of the hinge eye bore of the door retaining rod have an excess compared to the width of the leaf springs.
  • the dimension of the arc height of the curvature of the leaf springs also corresponds to the sum of the depth of the groove recesses in the circumferential wall of the hinge eye bore and half of its excess compared to the bearing pin.
  • the leaf springs are double-layered and have a substantially smooth, flat support and a spring part curved around an axis parallel to the bearing axis, the leaf springs each being formed from a free cut having an essentially rectangular outline shape , wherein the free end of the free cut is bent back with a curvature about an axis parallel to the bearing axis against the smoothly left connection area of the free cut with the holding plate.
  • the bearing pin is fixed in a one-armed bearing block with a tight fit and has a head which overlaps the hinge eye bore and the holding plate, and that the holding plate is arranged engagingly between the head of the bearing pin and the broad side of the door holding rod.
  • the design-related free spaces are sealed against contamination, in particular in the preferred embodiment, by a circumferential collar in the carrier part and that when a holding plate is used, the seal is formed by circumferential padding with intermediate tabs.
  • the bearing pin is fixedly connected to the support rod and the support rod bearing is arranged with the groove recesses in the bearing block.
  • a bearing pin 1 is fixed in a rotationally secure manner to a single-arm bearing block 3 via a shaft part 2 with a tight fit and engages with a bearing part 4 through a hinge eye bore 6 in a door holding rod 7 formed from a flat material blank End of the bearing pin 1 is provided with a head 8 overlapping the hinge eye bore 6.
  • the door holding rod 7 is supported by leaf springs 9, which are designed as spring tongues and are formed in one piece with a holding plate 10.
  • the leaf springs 9 are arched transversely to the axis 11 of the support rod bearing and plunge into radial groove recesses 12 in the peripheral wall of the hinge eye bore 6 of the door support rod 7.
  • the leaf springs 9 are connected to the holding plate 10, which is designed essentially as a flat plate and adjoins a door holding rod broad side 13, by means of a bend 14 directed perpendicular to the plane of the broad side 13 of the door holding rod 7, the length of the leaf springs essentially corresponding to the material thickness of the door holding rod 7 and the bend 14 of the leaf springs 9 forms an axially resilient support of the door holding rod 7 on the head 8 of the bearing pin 1.
  • the arc height of the curvature of the 15 of the leaf springs 9 corresponds to the sum of the depth of the radial groove recesses 12 in the peripheral wall of the hinge eye bore 6 of the door retaining rod 7 and the excess of the hinge eye bore 6 compared to the bearing pin diameter.
  • the leaf springs 9 are free by lying within the circular plan shape of the holding plate 10 and in its overlap area with the hinge eye bore 6 of the door holding rod 7 cuts formed.
  • the leaf springs 91 are curved around axes parallel to the axis 11 of the bearing and the radial groove recesses 121 have an oversize in relation to the width of the leaf springs 91.
  • the leaf springs 91 which are formed in one piece with the holding plate 100, are formed by free cuts of a star-shaped blank made of spring steel sheet (not shown in its development) and are first bent at 102 in parallel along the outline shape of the holding plate 100 and finally angled parallel to the bearing axis 11, such that that when mounting the mounting plate 100 rests on the head 8 of the bearing pin and the inwardly bent areas 101 of the leaf springs 91 resiliently rest on the broad side 13 of the door holding rod 7.
  • tabs 103 which are cut in one piece with the holding plate 100, are also bent at 104 parallel to the holding plate 100 and resiliently bent inwards against the broad side 13 of the door holding rod 7.
  • leaf springs 92 formed in one piece with a holding plate 110 are formed by cutouts 111 lying inside with respect to the plan shape of the holding plate 110 and at least largely in the area of coverage of the holding plate 110 with the hinge eye bore 6 of the door holding rod 7, the Cutouts 111 each have an essentially rectangular plan shape and a connection area 112 connecting them to the holding plate 110.
  • the leaf springs 92 are double-layered in such a way that the free end regions 113 of the free cuts 111 are turned over towards the connection region 112.
  • connection regions 112 form essentially smooth-surface supporting or supporting parts, while the folded regions 113 are curved around axes parallel to the bearing axis 11 and form the leaf springs 92 resting on the circumference of the bearing pin 1.
  • the holding plate 110 also engages between the head 8 of the bearing pin 1 and the broad side 13 of the door holding rod 7.
