Hinσe, in particular for a vehicle door

The present invention relates to a hinge, in particular for a vehicle door, with two hinge halves, which are 5 pivotably connected by means of a hinge pin and of fϊ which the one, fixed hinge half is intended to be fastened in a door post and has a lower edge, which forms a support for the other, movable hinge half.

10 In the manufacture of vehicle bodies, it is usually desirable, after hanging and adjustment of a vehicle door, to improve the accessibility for other work stages by again demounting the door. With conventional hinges, this has led to the adjustment of the hinges

15 being all too easily changed upon rehanging. In order to avoid the adjustment of hinges on the doors being changed, single-edge hinges are consequently now often used, that is to say the hinge pin is fixed at only one end. The disadvantage with such a design, however, is

20 that the stresses on the hinge pin become unfavourable and at the same time there is a risk of a door being unhinged inadvertently.

The aim of the invention is to eliminate the said 25 disadvantages and to produce an improved hinge, which makes possible simple demounting and rehanging of, for example, a vehicle door.

The aim is achieved according to the invention by the 30 fixed hinge half being made up of two parts, a lower part and an upper part, which are dismantlably connected to one another and between which the movable hinge half is mounted, the lower edge of the hinge being arranged on the lower part, and by the upper part ^ 35 forming an upper edge in the hinge, for fixing the upper end of the hinge pin, and being mountable and demountable while the lower part remains fixed, in order to make possible hanging and unhinging of, for

example, a vehicle door, without demounting the whole hinge.

According to a particularly advantageous embodiment, the upper and the lower parts are fixed to one another by means of a screw fastening and, furthermore, the upper and the lower parts can advantageously have locking elements, which prevent them from being mutually rotated.

By means of the embodiment according to the invention a reduction in stress on the hinge pin is achieved, and at the same time the movable hinge half can still be demounted simply from the fixed hinge half.

The invention is explained below in greater detail with reference to an embodiment shown in the drawings, in which:

According to Fig. 1, a vehicle door 1 is pivotably hung on the door post 2 in a vehicle body by means of a

10 hinge 3 according to the invention. The one, fixed hinge half 4 is mounted on the door post 2 and, by means of a hinge pin, pivotably supports the other, movable hinge half 6, which is mounted on the vehicle door 1. On the movable hinge half 6, there is a stop

15 7, which interacts with the fixed hinge half 4 and limits the opening angle of the vehicle door 1.

From Fig. 2 it emerges more clearly that the fixed hinge half 4 is made up of two parts, a lower part 8

20 and an upper part 9, which are dismantlably connected to one another, the lower edge 19 of the hinge being arranged on the lower part 8. The upper part 9 forms an upper edge 20 in the hinge and fixes the upper end of the hinge pin 5. The lower part 8 and the upper

25 part 9 are usually dismantlably connected to one another by means of a screw fastening, for example by means of a screw 10, which is threaded into the upper part 9. A locking element 11 in the form of a projection on the upper part 9 interacts with a

30 corresponding locking element 12 in the form of an upper edge area on the lower part 8 and prevents mutual rotation of the lower part 8 and the upper part 9. These locking elements can of course be designed in other appropriate ways. 35

As can be seen clearly from Fig. 5, the hinge pin 5 is intended to be axially locked in the movable hinge half 6. To this end, the hinge pin 5 is provided with two axially separated stop elements 13 and 14, between

which a projection 15 on the movable hinge half 6 is intended to be situated. The lower stop element 13 is constituted in the case shown here by a flange on the hinge pin 5, while the upper stop element 14 is constituted by a locking washer, which can, for example, engage with a groove 16 in the hinge pin 5 (see Fig. 10). At the bottom, the hinge pin 5 has a threaded section 17 for a nut 18 (see Fig. 2).

By means of the nut 18 and the flange 13, the hinge pin 5 can be locked against both axial displacement and rotation in the fixed hinge half 4. Locking against rotation can of course, however, also be effected in other ways, for example, by designing the lower end of the hinge pin 5 with some form of splines or similar, with corresponding shaping of course in the lower part 8. The threaded section 17 and the nut 18 can in this connection be omitted. Upon demounting of the hinge 1 according to the invention, the upper part 9 is first detached from the lower part 8 in the fixed hinge half 4 and can then be lifted off the hinge pin 5. After the nut 18 has been detached, the movable hinge half 6 together with the hinge pin 5, which is axially locked relative to it, can be lifted off the fixed hinge half 4. Rehanging is carried out in the reverse order.

Rotational locking between the hinge pin 5 and the fixed hinge half 4 can, instead of the way shown here, be achieved by means of suitable shaping of the upper part 9 and the upper end of the hinge pin 5. The nut 18 and the threaded section 17 of the hinge pin 5 are also unnecessary in such a solution.

A hinge according to the invention thus has a lower edge 19 (Fig. 2), which forms a support for the movable hinge half 6. The upper part 9, which forms a part of the fixed hinge half 4, reduces the stresses on the hinge pin 5 and secures the hinge against inadvertent demounting.
