Description

Hinge desensanchable for doors of motor vehicles ICAMPO DE LA INVENCIÓN which shows a conically shaped pleat, can be screwed to axial appendix provided with a peripheral thread and is subordinated to a correspondingly conical widening in the hinge eye bore separately with | barbonita the door of the vehicle already adapted and adjusted to the raw body after lacquering, and then reapply it to the body in its correct position, in the framework of the final assembly of the vehicle, without new adjustment work and I adaptation. In the above-mentioned known construction type of a hinge, the cylindrical area of the hinge pin, which fits in the hole of the hinge eye of the disengageable wing of the hinge and which has the same shape over the entire length of the hinge. hinge eye drill, must show respect to the width of the hole of the eye of the hinge a certain minimum tolerance, to make possible or facilitate in particular a mechanically supported re-application of the vehicle door to the body of the same. of the hinge eye in conjunction with the axially directed screwing, at the same time the mission of obtaining a centered position of the section of the hinge pin that fits in the hole of the eye of the hinge. The maintenance of the centering of the eye of the hinge of the other disengageable wing of the hinge in front of the pin of the same is based exclusively on the surface pressure, forced or supported by the screwing, between the cones on one side of the pin. of the hinge and, on the other hand, of the threaded nut and of the corresponding conical widening in each case of the hinge eye bore.

To counteract such a conformation of the hinge release wing support on the pin therein, a tendency to overturn the eye of the hinge in front of the pin thereof, resulting from the increasing weight of the current doors of the vehicles, in particular to Because of the mounting of motor drives, eg electric window lifts or similar, the threaded nut with the appendix ax has been screwed to the subordinate to it of the hinge pin in large part outside the hinge eye of the detachable wing of the same. By means of this arrangement of the screwing between the hinge pin and the threaded nut, although it can be prevented even in heavy vehicle doors, that the ojai of the disengageable wing hinge thereof assumes an inclined position with respect to the vehicle door. loosen gradually, it is therefore necessary that the hinge pin appendage of the hinge supporting the thread subordinate to the threaded nut complies with a rather large length, which however, unfavorably, a relatively long extraction stroke is obtained large for unhooking the hinge. 1 MARIO OF THE INVENTION Therefore, the invention! It has been imposed the mission of perfecting and in such a way a Disagra desenganchable for doors of motor vehicles? the type of construction cited at the beginning, that without raising the costs of manufacturing or assembly for the hinge of the door not only be safely avoided the previously illustrated loosening of the vehicle door, but is ensured with a conformation as short as possible of the hinge pin, including a hinge eye support extending between the two conical I-widens, and because an appendix in the form of a neck connected to the conical insert of the threaded nut fits in the first annular space between the hole in the eye of the hinge and the appendix of the pin of the hinge. This conformation of the hinge pin and the corresponding threaded nut opens the possibility of transferring the screwing of the threaded nut i and of the hinge pin largely towards i inside the eye of the hinge and, at the same time, of obtaining a very good radial support between the eye of the hinge and the pin of the same in the area of the two ends of the cylindrical longitudinal section of the eye hole of the hinge of the detachable wing thereof. The dislocation i of the coiled between! the pin of the hinge and the nut I! threaded in the eye of the hinge leads advantageously and at the same time also to a limitation of the extraction height necessary for the disengagement of the unhooked wing of the hinge, up to the amount of the height of the hinge eye itself. Parallel to the dislocation of the screw; hinge pin and threaded nut in the eye the hinge is obtained, apart from this and at the same time, also a reduction in the weight of the pin of the hinge, without this having been necessary to be satisfied with a high cost of manufacturing or a reduction in the stability of the attachment of the releasable wing of the hinge to the pin of the same. i It is planned here | especially that the outside diameter of the connect to the cone that! it tapers towards the free end of the hinge pin of the hinge pin flange, which fits between them! Industrial surfaces turned one! i towards the other of the hinge eyes of the two wings of the In connection with an arrangement, internal to the hinge eye bore, the uncoupling wing of the hinge, the screwing between the hinge pin and the threaded nut, for which it is characteristic that the threaded stud of the hinge pin should penetrate inwardly the threaded bore of the threaded nut only partially, an advantageous shaping of the threaded nut lies in that its threaded bore 1 is closed outwards by a cover, this cover being permanently or permanently attached to the body. of the threaded nut. By means of this the accumulation of dirt or lacquer or other material is prevented, within the area that remains open towards the outside of the threaded bore of the threaded nut, and thereby also any deficiency that could result from an output of these accumulations.

For a practical configuration of the threaded nut, according to the arrangement and the configuration of the tool holder of the threaded nut, it has different configuration shapes.

In a first form of configuration, it is provided that a threaded nut provided with a cover and with a polygonal outer extension i is formed as a nut of! One-piece cap or as a threaded nut equipped are a dome-shaped cap part placed on top.
