DESCRIPTION:
BRIEF SUMMARY
The invention relates to a hinge for a door or hatch, preferably for a motor vehicle, said hinge comprising two hinge halves, one of which is provided with a pivot pin and the other of which is provided with a bearing portion for pivot mounting on the pivot pin, said pivot pin having a spherical end portion, onto which the bearing portion fits with a complementary shaped cavity, and a narrower neck portion, a lock means being arranged to cooperate with the neck portion of the pivot pin and the bearing portion to lock said components against relative movement in the axial direction of the pivot pin.
The pivot pin in a door hinge, in a motor vehicle for example, is usually made as an essentially vertical, entirely circular cylindrical pin, which is fixed between a pair of mounting bracket arms, the bearing portion being a cylindrical sleeve surrounding the pin. The pin and the sleeve are mounted in their own mounting brackets, intended to be fixed to the door and the door post, respectively. The two hinge halves usually cannot be separated, which means that one hinge half must be detached from the door or the door post when the door is removed, and this means that when the door is remounted it must be realigned.
During body pre-assembly the doors are usually fitted and mounted, and during final assembly the doors are removed in order to mount the other door components, such as windows, locks etc., while the interior of the car is completed. It is therefore possible to save considerable time if one can avoid aligning the doors for a second time during final assembly.
Several different solutions have been presented, based on taking the hinge apart to avoid realignment or readjustment when the door is remounted, e.g. by removing one portion of a two-piece fixing plate or by removing a rotatable and lockable loose pin. This work is physically demanding and must be combined with manual fixtures to hold the door or the hatch in position prior to re-hanging or after removal.
The purpose of the present invention is to provide a hinge which makes it possible in an automatic process to remove and re-hang doors and hatches quickly and simply while retaining predetermined tolerances without requiring any manual steps in connection with this operation.
This is achieved according to the invention by virtue of the fact that the bearing portion comprises a bearing sleeve to be journalled on the pivot pin, a bearing housing, the inside of which fits over the outside of the bearing sleeve, and a fastener means for detachably fastening the bearing sleeve to the bearing housing.
The invention provides pivot mounting in the hinges without tension, which makes it possible during hanging or removal of the door to permit slightly non-parallel alignment of the upper and lower hinges. This permits an increased level of automation during assembly and the reduction of assembly time.
The invention will be described in more detail below with reference to the accompanying drawing, in which
FIG. 1 is a side view of a hinge according to one embodiment of the invention, in the form of an upper hinge of a passenger car door,
FIG. 2 is a view of the hinge in FIG. 1 as seen from the left in FIG. 1,
FIG. 3 is a partially cut-away side view of a portion of the hinge in FIG. 1 on a larger scale, and
FIG. 4 shows a section along the line IV--IV in FIG. 3.
The hinge shown in the drawing essentially consists of a first hinge half 1 and a second hinge half 2, which are designed to be mounted on a door post and a door, respectively. The first hinge half 1 comprises a mounting plate 3, consisting of two pressed sheet metal parts welded together and provided with screw holes 4 for mounting screws, and an essentially horizontal supporting arm 5 into which a pivot pin 6 with an essentially vertical longitudinal axis is securely screwed. The second hinge half 2 comprises a mounting plate 7 with screw holes 8 for mounting screws and a bearing portion 9 for pivot mounting on the pivot pin 6. The bearing portion 9 is welded to the mounting plate 7.
