Description

DOOR DOOR STRUCTURALLY COMBINED WITH A REMOVABLE DOOR HINGE Field of the Invention The present invention relates to a door stop structurally combined with a removable door hinge for automotive vehicle doors, the door hinge comprising a first hinge half, which can act on a part of the door assembly, the door or the door post, and a second half of the hinge, which can act on the other part of the door assembly, and also a hinge pin, which is fastened on one half of the hinge with an operating adapter, and in the other half of the hinge in such a way that it can be raised in a secure rotary manner, and the door stop comprising, braking and securing means, which are arranged aligned radially with respect to the hinge pin shaft, which interacts with the support means arranged concentrically with respect to the axis of the hinge pin, and are fully accommodated in the cover of the door stop which is placed, in an axial extension of the axis of the hinge on the middle of the hinge, on which the hinge pin is mounted with an operating adapter.

BACKGROUND OF THE INVENTION Although the door stops of this type, which are structurally combined with a door hinge, are distinguished by a comparatively small installation space requirement and can also be implemented in a multiplicity of modified modes to a greater or lesser extent. , but its production still requires a considerable amount of individual parts which have to be produced and adapted separately. Therefore, the door stops of this type are basically affected by a production expense, which is still excessively high and at the same time, with certain uncertainties with respect to the specific positions of fastening the door that have always been been maintained. Furthermore, the result of the quantity of components required, of the stop for the door, is that the probability of finding unfavorable coupling tolerances is increased and therefore, obviously an increased production of noise sources, which can be attributed to the unfavorable tolerance couplings inside the door stop. Finally, the multiplicity of individual components requires having the corresponding inventory, both for the manufacturer and for the spare parts warehouseman. However, the disadvantage that it has not been possible to standardize the top of the door and its components is particularly serious. In addition, the hinges of the doors of motor vehicles having an integrated door stop have already been known for the effect of the hinge pin, which consists of solid material of the hinge formed from a first and a second half of the hinge. the hinge which is secured to the stump in a non-rotational manner of one half of the hinge and is held in the stump of the other half of the hinge in such a manner that it passes through at least one journal with a bearing space . In conjunction with said hinge design, the configuration of the integrated door stop, is distinguished by a hinge pin, together with a complementary formation of the stump hole of at least one stump of that hinge half, to through which journal passes with a space of the bearing, which has at least a part of its region or regions of the length designated to each of these trunnions, a rounded profile of its cross-section, whose profile deviates from the shape pure circular. Although said braking and door stop devices integrated in a door hinge are distinguished by an extremely small installation space requirement, and also only require a small amount of individual parts, they are affected by the disadvantage of the machining of the door. half of the hinge through which stump passes the hinge pin with the bearing space, which is extremely complicated. Therefore, the present invention is based on the objective of improving a door stop which is structurally combined with a removable door hinge, and which is intended to be used for automotive vehicle doors of the type mentioned at the beginning, for the purpose of of the production of the stopper unit, regardless of the operation of stopping the door in and in the least noisy way possible, is sufficiently improved so that with the standardization of a smaller number of individual parts, they are obtained at less some of the components of the top of the door, and in addition, a unit of stop of the door much more economic. According to the present invention, this object is achieved essentially because the hinge pin, together with a complementary non-circular shape of the inner wall of the circumferential-shaped door stop cover, which is connected to the middle of the hinge through which journal passes with the space of the bearing has, at least, a part of its region of length, which fits into the cover of the top of the door, a rounded profile of its cross-section, profile deviates from the pure circular shape. In this case, in order to save a complicated shape, the cover of the door stop is advantageously formed by a section of length of a continuous hollow profile material, and is secured by means of positive closing means of a securely rotatable manner on the surface of the outer joint of said hinge half, through which journal the hinge pin passes with the bearing space. The cover of the door stop is quickly secured in the middle of the hinge by means of a mutual positive locking latch, particularly in such a way that the cover of the door stop is connected, by means of at least one axial extension of its wall with a shape of half circumference, in a positively closing manner to a step correspondingly configured in said hinge half, through which trunnion the hinge pin passes with the space of the bearing. However, in a modified design form of the positive locking latch of the door stop cover and the hinge half, the door stop cover may also be indented at the end. , which interacts with an indentation designed in a complementary manner on the surface of the outer joint of the middle of the hinge, through which the hinge pin passes with the bearing space. Regardless of how they can be considered in detail, the mutual positive locking latch of the door stop cover and half of the hinge, an advantageous form of securing is achieved when the door stop cover, which is formed by a section of length of a continuous hollow profile material is fastened on the positive closing hook without the matching profile on, on, or in the middle of the hinge, by means of an embedment sheave, which rests at one end Free of the door stop cover and is supported against the hinge pin in an axial direction. In addition, in a development of the lock or connection of the cover of the door stop to the middle of the hinge, it is also provided that the lateral end of the cover with the stop of the door on this side, which is provided with at least, an axial projection or an end profile, to be sealed with respect to the surface of the hinge half by sealing means. With respect to the design of the braking and fastening means of the door stop, a simple but effective mode, is the result of the fact that the circumferential inner surface of the door stop cover, and the circumferential outer surface of that region of the length of the hinge pin reaches through the cover of the door stop, each has a purely rounded deviation in its circumferential surface which protrudes with respect to the cylindrical shape. However, in most applications, it will be necessary to adapt the stop of the door with a plurality of braking and holding positions, for which purpose, it has also been provided that the hinge pin has on its circumference, two deviations from the exactly circular cross-sectional shape, separated one from the other, whose deviations protrude radially with respect to the circular shape, two deviations from the diameter, which protrude radially with respect to the circular shape of the hinge pin, being arranged in such a way . that lie one in front of the other. Depending on the intended braking and securing positions of the automotive vehicle door, with respect to the distribution of the braking and securing means, a straight line has been provided which crosses the highest points of the mutually opposite rounded deviations, which They protrude radially from the hinge pin to form an angle of 90 ° with respect to the straight line passing through the location of the stop, and the hinge pin.

Summary of the Invention However, the corresponding provisions have also been taken for the intended distribution, for the highest points of the rounded deviations projecting radially from the hinge pin, so that they are accommodated, aligned at an angle, one with respect to the other. Finally, the present invention can also be further refined, so that the circumferential inner surface of the door stop cover and / or that length section of the hinge pin, which is engaged in said cover, are provided with a sliding coating or with additional hardening of the end layer.
