Definitions

• the present invention relates to a hinge device, in particular but not necessarily for the attachment of a door to a body of a motor vehicle.
• a hinge device is formed by a pair of arms, each of which engages with one end on a body-fixed axis and with another end on an axis connected to the door.
• the effective length of these two arms i.e. The distance between its two axes must be the same, and the distance between the two door-side axes on the one hand and between the two body-side axes on the other hand must be the same so that the door maintains its orientation when opening and closing and in an open position next to it the door opening and parallel to this can be applied to the body.
• the parallel movement of the door means that the
• the object of the present invention is to provide a hinge device for connecting a movable part to a stationary part, in which the stationary part passes through at least one position rotated relative to these parallel positions between two mutually offset but parallel aligned positions.
• the object is achieved by a hinge device with the features of claim 1.
• these two parallel positions can correspond to a closed position of the door and an open stop position of the door, in which it lies offset against the body parallel to the closed position. Because a rotated position is traversed between the closed and the parallel open position, the movement when the door is closed is not an exact parallel translation, so that a pressure build-up inside the vehicle is avoided and the door can fall into the lock unhindered. If the twisted position is suitably oriented in relation to the headwind, the wind pushes the door in the direction of the closed position, an unexpected tearing of the door is impossible.
• the distance of a first point of impact at which the pull strap is located should be in a first of these limit positions the first pulley meets the axis of this first pulley smaller than the distance of a second point of impact at which the tension belt hits the second pulley from the axis of the second pulley, while in the second limit position the spacing relationships should be reversed. This results in gear ratios greater or less than 1 between rotations of the head pieces in relation to the arm in the different limit positions.
• the at least one non-circular pulley is preferably elliptical.
• the other pulley is preferably circular or also elliptical. If both pulleys are elliptical, they should be suitably oriented in relation to one another in order to achieve a strong pivoting of the door between the two limit positions. For two ellipses of a given shape and of the same circumferential length, the maximum swivel stroke is reached when, in a position of the first pulley in which the points of impact of the belt on the first pulley are the points of intersection of the long axis with the circumference of the ellipse, the points of impact occur the other pulley at the intersection of the short axis with the circumference.
• the arm is angled and the tension belt is deflected between the pulleys on two rollers.
• FIG. 1 shows a schematic section through a hinge device not according to the invention. tion according to a not previously published patent application by the applicant;
• FIG. 2 shows a section analogous to that of FIG. 1 through a first embodiment of a hinge device according to the invention
• FIG. 3 shows a section analogous to that of FIG. 1 through a second embodiment of the hinge device according to the invention
• FIG. 4 shows a section through a third embodiment of the hinge device on a vehicle body with the door closed
• 5 shows a section through the third embodiment with the door open until it stops; 6 shows the position of the belt on the belt pulleys when the door is closed according to a modification of the third embodiment;
• Fig. 7 shows the corresponding positions of the belt with the door open.
• FIG. 1 shows a horizontal section through a door 1 of a motor vehicle and pillars 8, 9 laterally surrounding the door 1 of a body of the motor vehicle.
• a hinge device generally designated 10, comprises a first head piece 2 fastened to the door 1 and a second head piece 7 fastened to the right column 8, as well as an arm 5 to which the head pieces 2, 7 are each articulated pivotably about an axis.
• the arm 5 is through a hollow housing formed in the interior of which two pulleys 3, 6 are rotatably connected to the head pieces 2 and 7 through openings in the arm 5.
• An endless tension belt 4 is looped around the circumferential surfaces of the two pulleys 3, 6.
• the pulleys 3, 6 are both circular and have the same diameter, so that a rotation of a head piece 2 or 7 with respect to the arm 5 with the aid of the pull belt 4 in an equally large rotation of the other head piece 7 or 2 is translated. Consequently, the door 1 always remains in the same orientation when moving between its closed position between the columns 8, 9 and an open position.
• the first embodiment of the hinge device 11 according to the invention shown in FIG. 2 corresponds to that shown in FIG. 1 in all of the above, with the exception of the shape of the first pulley 3.
• this has an out-of-round, more precisely an elliptical cross section.
• points of impact 12, 13 at which the two strands of the tension belt 4 tangentially touch the pulley 3, essentially on a short axis of the ellipse drawn in as a dash-dotted line K.
• the head wind would strike the outside of the partially opened door shown as a dotted outline in FIG. 2.
• the door 1 would, if it is opened while the vehicle is moving, pushed into its closed position by the airstream. This prevents accidental opening of the door while driving through the wind.
• the impingement points 12 to 15 of the tension belt 4 move on the pulleys 3, 6, the distance between the impingement points 12, 13 from the axis of rotation of the pulley 3 continuously increasing while the corresponding distance at the points of impact 14, 15 of the circular pulley 6 remains the same.
• the points of impact are located 12, 13 each at the intersection of a long axis L of the ellipse with the peripheral surface of the pulley 3, and the orientation of the door is the same as in the closed position.
• a prerequisite for the orientation of the door in the open and closed position being the same is that the path of the points of impact on both pulleys when opening and closing is the same.
• this corresponds to the requirement that the circumferential length of both pulleys 3, 6 must be the same.
• the door-side pulley 3 is elliptical and the column-side pulley 6 is circular
• the same result could also be achieved by using a circular pulley 3 on the door 1 side and an elliptical pulley 6 on the column 8 side, but with one compared to Fig. 2 rotated by 90 ° orientation of the elliptical pulley, so that again in the closed position of the door, the distance of the impact points 14, 15 of the tension belt on the pulley 6 is greater and in the open position smaller than the distance of the impact points 12, 13 on the pulley 3.
• An increase in the pivoting movement is achieved, as shown in the exemplary embodiment in FIG. 3, by selecting both pulleys 3, 6 elliptically with the same dimensions, but with long axes L rotated relative to one another. If the long axes L were not twisted, parallel to each other, the door 1 would not pivot when moving. A maximum swivel stroke is achieved when the long axes L of the two ellipses are oriented perpendicular to one another.
• FIGS. 4 and 5 show a third embodiment of a hinge device according to the invention on a door of a motor vehicle. Parts in these figures which are identical or functionally identical to parts shown in FIGS. 1-3 have the same reference numerals and will not be explained again in detail.
• the hinge device 20 here according to this third embodiment differs from those of FIGS. 2 and 3 by the angled shape of its arm 5.
• the pull strap 4 inside the arm is deflected on two rollers 21 by an angle of 90 °.
• the belt pulleys 3, 6 wrapped by the tension belt 4 are both elliptical, as in the embodiment of FIG. 3, and in the closed position of FIG.
• the points of impact 12, 13 of the belt on the belt pulley 3 are at the intersection points of their short Axis K with the circumference and the impact points 14, 15 of the pulley 6 at the intersection points of the long axis L with the circumference.
• This placement ensures that immediately at the beginning of the opening movement of the door 1, the transmission ratio of the pulleys 3, 6 deviates the most from 1 and then continuously approaches 1 and finally falls below it.
• the long axes L of both ellipses are parallel here. As already explained with reference to FIG. 2, it follows from the distances of the impingement points 12 to 15 from the axes of rotation of their pulleys 3, 6 that the door 1 initially pivots counterclockwise when opened.
• the pivoting movement changes its direction to the extent that the points of impact 12, 13 approach the point of intersection with the short axis K and the points of impact 14, 15 approach the point of intersection with the long axis L.
• the striking position which corresponds to a complete opening of the door 1
• the impingement points 12, 13 on the pulley 3 have already moved beyond the intersection points with the long axis or the impingement points 14, 15 on the pulley 6 beyond the intersection points with the short axis.
• the orientation of the door 1 in the open stop position is exactly parallel to the orientation in the closed position, because the dimensions of the two pulleys 3, 6 are chosen slightly different.
• FIGS. 6 and 7 Another possibility of ensuring parallel orientations of the door in the closed state and in the open stop state with two identical pulleys 3, 6 is shown in FIGS. 6 and 7, with the arm 5 only being drawn in fragments and the pulleys for the sake of clarity 3, 6 are shown enlarged.
