  • a further door hinge with integrated stay mechanism is disclosed in the DE 199 53 077 B4.
  • a pressure tappet is pressed against a profiled circumference section of a hinge shaft which comprises three predetermined stay positions. With such a hinge it is possible to hold the motor vehicle door at three predetermined stay positions.
  • the problem underlying the present invention relates to provide a hinge comprising an integrated stay mechanism, which allows to reliably hold for example a door in each arbitrary angular position.
  • this hinge should be as simple in construction as possible, be cost efficiently produc- ible and should reliably function over the complete life span of the motor vehicle. It is further desirable, that the hinge comprises a relation between holding torque and opening torque as high as possible. Further, the stay mechanism should be as invisible as possible which leads to an aesthetically pleasing hinge.

  • Figures 1 and 2 show the basic arrangement of a hinge 1 having a first hinge part 10, a second hinge part 20 and a hinge shaft 30, which defines the pivoting axis of hinge 1.
  • the second hinge part 20 is pivotable with respect to the first hinge part 10 around the hinge shaft 30.
  • hinge 1 is used for fixing the door or a motor vehicle (not shown)
  • the second part 20 is mounted to the car body of the motor vehicle by means of ordinary screws (not shown), which are inserted into mounting openings 24 of a mounting plate 22.
  • the first hinge part 10 also comprises a mounting plate 12 with mount- ing openings 14, to mount the first hinge part 10 by means of ordinary screws (not shown) to the door of a motor vehicle.
  • Fig. 1 also shows a first fixing element 40, which is shaped like a bushing and which is arranged around the hinge shaft 30.
  • the further components of the stay mechanism integrated into hinge 1 are almost not visible from the outside. Therefore, the hinge 1 shown in Fig. 1 is particularly preferably under esthetic aspects. Further it is comparably small. Therefore, only little space is needed, to integrate hinge 1 into a motor vehicle door.
  • Figs. 3 and 6 show the inner components of the stay mechanism of hinge 1.
  • Hinge 1 comprises a hollow prismatic or cylindrical portion 21 which was cut in Fig. 3 to show the inner components.
  • a spring element 70 is arranged, which pushes a second fixing element 50 in direction of a guiding surface 42 of the first fixing element 40.
  • the second fixing element 50 is a tappet 50 which is biased by means of a spring 70 in direction of the hinge shaft 30 as indicated by arrow 51 in Fig. 6.
  • the hollow prismatic/cylindrical portion 21 is closed by means of a set screw at the side opposite to the tappet 50 (not shown), which acts as a stop for the spring element 70.
  • the spring force of the spring element 70 can be adjusted by screwing the (not shown) set screw into or out of the hollow prismatic/cylindrical portion 21. In this case the spring element 70 is pre-biased stronger or weaker.
  • Fig. 3 shows further the first fixing element 40, which is formed as an essentially cylindrical bushing 40.
  • the bushing 40 is rotatably supported onto the cylindrical hinge shaft 30 and therefore around the pivoting axis of the hinge 1, as it is indicated by arrow 41 in fig. 6.
  • This rotation is selectively prevented or allowed by means of a friction clutch 60, 62 in form of a first 60 and a second clutch pin 62.
  • the way of operation of the friction clutch in cooperation with the other components of the stay mechanism is explained in detailed further below.
  • the two axis parallel clutch pins 60, 62 are preferably pressed away from each other by means of one or a plurality of spring elements (not shown) perpendicular to its longitudinal axis.
  • the spring elements can be normal springs or elastic elements for example rubber blocks or bands.
  • the clutch pins 60, 62 are arranged between the first fixing element 40 and the pivot shaft 30 and selectively prevent or allow a rotation of the first fixing element 40 with respect to the hinge shaft 30 rigidly connected to the first hinge part 10.
  • the clutch pins 60, 62 are located within a preferably sickle shaped portion 45 of the inner bore 46 of the first fixing element 40, as shown in figs. 5 and 6.
  • the portion 45 is therefore provided as a preferably sickle shaped pocket 45, which inner diameter decreases in direction of the ends 48 of the sickle. Therefore, the clutch pins 60, 62 seize if they are pressed in direction of the ends 48, and prevent in one movement direction respectively rotation of the first fixing element 40 around the hinge shaft 30.
  • Another configuration to achieve this clutch effect is shown in Fig. 13.
  • the hinge shaft 30 comprises a flattened portion 32 and the inner bore 46 of the first fixing element 40 is round and has a constant diameter. This configuration provides also two ends 34 at which the clutch pins 60, 62 seize if they are pressed in direction of the ends 34. Again, the clutch pins 60, 62 prevent rotation of the first fixing element 40 around the hinge shaft 30 in one movement direction, respectively.
  • the first fixing element 40 comprises at the outside a contoured guiding surface 42 which exactly has one portion 44 that defines a stay position.
  • the portion 44 is preferably shaped as a notch or groove 44, which is recessed in parallel to the hinge axis 30 into the essentially cylindrical guiding surface 42.
  • Figure 3 and Fig'ire 6 show hinge 1 while the second hinge part 20 is located ?X the stay position with respect to the first hinge part 10.
  • the spring element 70 presses the tappet 50 in direction of the first fixing element 40.
  • the tappet 50 comprises an end 52 which faces the first fixing element 40 and which is preferably half cylindrically shaped and preferably comprises a pin 52 which can be made of a different material than the tappet 50. In the shown position the end 52 respectively the pin 52 engages the notch 44 for the stay position.
  • the end 52 has to move out of the portion 44 against the spring force of the spring element 70.
  • a defined holding torque Tp has to be overcome, as shown in Fig. 12.
  • the holding torque T P can be adjusted by means of the shape of the end 52, the shape of the portion 44 and the spring force of spring element 70. It should be at least that high, that for example an undesired closing or opening of a motor vehicle door is reliably prevented. On the other hand it should also not be excessively high, such that elderly persons or children can close a motor vehicle door without problems.
  • the holding torque T increases from 0 to Tp, as the first angular section 202 of the diagram 200 of Fig. 12 schematically shows. If the pivoting movement co of the hinge parts 10, 20 to each other is con- tinued after exceeding the holding torque T P via c ⁇
  • clutch pins 60, 62 happens automatically, by supporting them within two curve shaped slots 28 in opposite sides of the prismatic/cylindrical portion 21, as shown in Fig. 2 and Fig. 16.
  • one of the clutch pins 60, 62 is pressed to the center of the sickle shaped portion 48 by one end of the slots 28, as indicated by the ai ⁇ ows 64 in fig. 6, whereby the seizing of the clutch pin 60, 62 is revoked.
  • the second hinge part 20 comprises two slots 28 which are arranged at the prismatic/cylindrical portion 21 adjacent to two bores 26 which support the hinge shaft 30.
  • the slots 28 may form a common opening with the bores 26 like it is shown.
  • the pins 60, 62 may be actuated in another way than with slots 28. It is however important, that the actuation of the pins 60, 62 is related to the relative pivoting movement of the second hinge part 20 with respect to the first fixing element 40.
  • first fixing element 40 is moved respectively pivoted together with the second hinge part 20 in direction 23, as indicated by arrow 41 in Fig. 6, by means of the friction of the end 52 of the tappet 50 at the guiding surface 42 of the first fixing element 40.
  • the first fixing element 40 thus rotates with respect to the hinge shaft 30, such that its portion 44, which defines the stay position, is also moved further, to define a new stay position.
  • the clutch pin 60 again clutches and prevents a rotation of the first fixing element 40 with respect to the hinge shaft 30.
  • the end 52 of the tappet 50 again latches within the portion 44 of the first fixing element 40 and therefore locks the hinge 1 at the new stay position:
  • the stay mechanism is effective in both pivoting directions.
  • the clutch pin 62 is provided, which clutches and disengages in the above described way.
  • FIGS 14 and 15 show a further embodiment, wherein the hinge shaft 30 or the first fixing element was modified to provide a hinge 1 which comprises a defined angular range where no locking effect occurs. If the hinge pivots through this angular range it does not apply any resistance torque T. This effect is used near the closing position of the hinge 1 to facilitate the closing movement of an automotive door.
  • Fig. 14 shows a configuration according Figs. 3 -5 wherein the first fixing element 40 comprises a sickle shaped pocket 45, which inner diameter decreases in direc- tion of the ends 48 of the sickle.
  • the shaft 30 in addition comprises a flattened portion 36 to provide the non-locking range. If the hinge 1 rotates, such that the flattened portion 36 and the pocket 45 face each other, the pins 60, 62 disengage or can not engage, such that the first fixing element 40 is free to rotate along a defined angular range. This angular range is defined by the shape an size of the flattened portion 36.
  • Fig. 15 shows a configuration according Figs. 13 wherein the hinge shaft 30 comprises a flattened portion 32 and the inner bore 46 of the first fixing element 40 is substantially round.
