Definitions

  • the invention relates to a mechanical door arrester for motor vehicle doors, consisting of a holder housing arranged on a door arrangement part, door or door frame and a door holding band which is articulated on the other door arrangement part and which penetrates the holder housing and is formed from a flat material blank, and at least one arranged in the holder housing, with the broad sides of the Interacting door holding band, consisting of at least one adjustable pressure element and a brake or abutment element arranged fixedly opposite the latter in the holder housing, for applying a braking or holding force for the motor vehicle door.
  • Mechanical motor vehicle door locks of conventional design are characterized in that one or more locking marks are arranged on the door holding band, distributed over its length, with which the braking or holding device in the holder housing interacts in such a way that the motor vehicle door brakes in one or more predetermined opening positions and is held.
  • the motor vehicle door in the area of the respective stop mark still experiences an acceleration independent of the user of the vehicle until it is finally braked and held by the braking and holding device at the point indicated by a stop mark becomes.
  • Door locks of this type have proven to be extremely disadvantageous in that, under spatially restricted conditions, such as in garages or in parking lots, the door opening angles indicated by the locking marks on the door retaining strap cannot be reached without the motor vehicle door being parked on the wall of the garage or on an adjacent one Vehicle comes to a stop.
  • a braking and holding device designed as a clamping device and accommodated in the holder housing is provided for this purpose, the braking and holding device being a pair of rolling bodies, in particular cylindrical rollers, and one associated therewith on both broad sides of the door holding band Cage supported against a spring load on one side in the holder housing, such that the cage receiving the rollers is tiltably supported in the holder housing and the holding force required for fixing the motor vehicle door in any open position by jamming the cylindrical rollers on the one hand against the door retaining band and on the other hand against the cage he follows.
  • a disadvantage of this type of door arrester is first of all the fact that the pinch rollers are constantly in contact with the door retaining band under a certain spring load and the motor vehicle door is therefore fundamentally never freely movable. Furthermore, the application of a holding force sufficient to hold the motor vehicle door in any open position requires the use of a correspondingly strong loading spring for the cage holding the cylindrical rollers, as a result of which the door arrester is not only complex or expensive overall, but also causes the motor vehicle door to become stiff.
  • a mechanical door lock is already known, which, according to the freewheeling principle, enables the door to be locked as desired within a selected opening angle range, and in conjunction with a brake abutment formed by a wedge piece, the use of a free in a holder housing movably arranged, with the door handle proposes a constant contact pressure element in the form of a roller and a curve surface associated therewith arranged opposite the door holding rod.
  • a door support rod provided with a start-up ramp over a corresponding length range must be used.
  • Such a design of a door arrester has the disadvantage, on the one hand, of a high manufacturing outlay and, on the other hand, of the effectiveness limited to a selected opening angle range of the door.
  • the invention has for its object to provide a mechanical door lock for motor vehicle doors, which is characterized by a simple structure and in operation a free movement of the motor vehicle door over its entire opening area allows, on the other hand, an exact setting of the motor vehicle door in any open position in such a way that even an occasional, unintentional bumping of the vehicle user on the partially open motor vehicle door does not lead to loosening and thus moving the motor vehicle door determined in a selected open position.
  • the door holding band has completely smooth broad sides and the braking or holding device is pivotally mounted in a shape of the holder housing, in its, by means of a head part Holding position aligned perpendicular to the plane of movement of the door holding band, pressure element, the greatest height of which is slightly greater than the distance between its housing-side bearing and the surface of the door holding band and that the adjustment of the Depending on a reversal of the direction of movement of the door retaining band, a pressure element is assigned a driver that interacts positively with the pressure element and secondly frictionally with the surface of the door retaining band, the driver being accommodated within the holder housing in both directions of movement of the door retaining band with a clearance such that the driver does that When the direction of movement of the door strap is reversed, the pressure element is transferred into its pressure or operative position.
  • a motor vehicle door arrester in which a pressure element mounted tiltably in a holder housing depending on the direction of movement of the door holding band is provided in the holder housing for the purpose of locking the door is known per se from US Pat. No. 2,939,166, but must be used with this known type of a door arrester the spring element which cooperates with one of the two narrow sides of the door holding band can be assigned a spring load which ensures a permanent contact of the pressure element with the door holding band, with the most undesirable consequence that the pressure element constantly grinds on the door holding band and thus, besides a constant inhibition of the mobility of the Doors also form a constant source of noise.
  • the mechanical door arrester according to the invention for motor vehicle doors not only enables the motor vehicle door to be more or less loosely fixed in any open position, but also to fix the motor vehicle door in any opening position in such a way that an unintentional bumping on the motor vehicle door or the like, as it is almost inevitable when getting in and out of less experienced people, can not lead to a lifting of the definition of the vehicle door in the selected opening position.
  • the mechanical door arrester according to the invention can be manufactured and assembled in the same way as the known door arrester with a fixed permissible opening angle of the motor vehicle door.
  • the pressure element is formed by a pendulum body which is pivotally suspended in the holder housing about an axis directed transversely to the direction of movement of the door holding rod, the length of which is slightly greater than the distance of its articulation axis from the surface of the unloaded door holding band facing it.
  • the pendulum body has an essentially triangular cross-sectional shape and, on its side which cooperates with the surface of the door holding band and is curved concentrically to its articulation axis, has two edges which are arranged at a distance from one another in the direction of movement of the door holding band and come into linear engagement with the door holding band.
  • edges of the pressure element designed as a pendulum body which engage linearly with the surface of the door holding band, are advantageously formed by two strip-shaped projections arranged in its general longitudinal direction and at a distance from one another, and on one at a flat angle, in particular at an angle of 7 degrees to Surface plane of the door strap aligned movement path arranged.
  • the arrangement of the edges engaging with the surface of the door holding band on one with the plane of movement of the door holding band a flat angle, in particular an angle of 7 degrees includes a self-reinforcing effect of the pressure element in such a way that the pressure force to be applied is disproportionately increased when the door strap is moved further.
  • the pendulum body is pivotably mounted via a partially roller-shaped head part in a correspondingly shaped recess in the upper holder housing wall or in a bearing plate adjacent to it, and that the driver sliding on the door holding band has an essentially H has shaped cross-sectional shape and engages in a longitudinal slot recess of the pendulum body, such that it interacts positively with the pendulum body forming the pressure element.
  • two mutually independent, mutually independent pendulum bodies can of course also be provided.
  • the driver is advantageously provided with a sliding coating on its side surfaces facing the associated guide surfaces of the holder housing.
  • the brake or abutment element arranged opposite the pressure element expediently consists of one or more sections of a friction material, in particular a brake lining material, and a lining carrier carrying this, the lining carrier for the friction or.
  • Brake material has two mutually perpendicular inclined surfaces and one of these inclined surfaces has a correspondingly inclined wall of the holder housing, the other of these inclined surfaces one in a threaded bore of the holder housing. ses recorded adjustment screw is assigned such that the section or sections of a friction material or a brake pad material according to their wear progress are adjustable and thus the door arrester can apply adjustable braking or holding forces regardless of its operating time.
  • the holder housing consists of a folded sheet metal section and, as shown in particular in the illustration in FIG. 2, the door holding band 1 is provided with a recess or recess 40 which is adjacent to the articulation 3 of the door holding band 1 is arranged and which ensures that a fixing of the door is not possible within a certain opening angle defined by the length of the recess 40.
