METHOD AND DEVICE FOR SECURING HINGE FOR VEHICLE DOOR
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION The present invention relates in general to a method and device for relatively accurately securing a vehicle door to the body during manufacture, allowing the door to be removed from the body to mount accessories on the door, and then returning to easily mount the door to the body in the original joint arrangement. DESCRIPTION OF THE PREVIOUS TECHNIQUE In the manufacture, the assembly of a vehicle door to the body involves a procedure of two separate operations, specifically (1) a precise assembly of the door to the body to continue to beat from a fully open first condition. to a second closing position to the body door opening; and (2) mounting a variety of accessories to the door (i.e., windows, door locks, inner leather covers or fabric for the door). Due to manufacturing tolerances of bolt hole parts and locations, an initial custom fit of the door to the body is required to ensure proper positioning. After the precise assembly of the door and the frame, in the past it was customary to apply protection against rust and paint to the door, after which the doors were removed from the frame and accessories were added in another work station. The final reassembly of the fully equipped door to the body could, in this case, cause damage to the door, accessories and adjacent panels of the body, in case of need of realignment of the door. OBJECTS AND SUMMARY OF THE INVENTION It is a primary object of the present invention to provide a method and device for the initial assembly of an automotive vehicle door in the body, in a precise predetermined arrangement, which allows to easily remove the door from its mounting frame Accessories on the door, and facilitate the reinstallation of the door to the predetermined layout without damaging the door or accessories. Another object of the present invention is to minimize the labor of reinstallation in the manufacture of a motor vehicle door to the body, while at the same time the adjustment of the door to the body is improved. Still another object of the present invention is to provide an improved method and device for assembly during the manufacture of a door to a motor vehicle body, minimizing damage to doors and bodies during this assembly. In accordance with the practice of a first embodiment of the present invention, one or more door hinges are adjustably fastened to the respective body frames (typically designated pillars) by the instrumentality of bolts with rope. More particularly, the hinges and pillars have slightly larger openings that can be aligned with one another during assembly. In addition, a reinforcing nut plate has a series of openings with rope that can be aligned with the openings in the hinge and the pillars to receive the ends of bolts with rope. In the initial manufacturing assembly of the hinge pillar and the nut plate, one or more bodies of hot adhesives are interposed between the nut plate and the pillar. By subjecting the door to a conventional anti-rust procedure (known as "E coating"), the associated elevated temperature activates the hot adhesive bodies so that the opposite surfaces of the nut plate and the pillars are secured with one another in a desired predetermined arrangement. Therefore, the bolts and the door can be removed to add accessories. Reassembly of the door with accessories will be in a predetermined fine adjustment arrangement that does not require realignment adjustments. In a second modality, the pillar and another plate are welded to one another instead of using hot adhesive as in the first mode. A safety screw secures the welded assembly to the hinge when the bolts are reapplied. DESCRIPTION OF THE DRAWINGS In the attached drawings: Figure 1 is an elevated, partially sectional and enlarged view of connecting pieces from a door hinge to the pillar, according to a first embodiment of the present invention. Figure 2 is a raised view showing the hinge of the door joined in a predetermined adjustment arrangement to a pillar of the body. Figure 3 is a raised view of an alternative embodiment of the present invention. DESCRIPTION OF THE PREFERRED MODALITIES With respect to the drawings, and particularly to Figure 1, a motor vehicle door 10 (shown schematically) includes one or more hinges 12, each of which is rotatably interconnected to the door by a pivot bolt. or shaft 14. The hinge includes a generally flat plate 15 having a pair of apertures 16 and 18 of low tolerance for receiving mounting bolts 20 and 22, respectively. In addition, a pilot aperture 24 and a large security aperture 26 are formed in the plate 15 for a purpose which will be explained hereinafter. A vehicle body pillar 28, to which a door typically joins, generally extends vertically and is strong enough to withstand repeated knocks when opening and closing, due to the normal use of the automobile. The pillar includes a relatively flat extension 30 in which large openings 32 and 34 are aligned with hinge openings 16 and 18, when a pilot opening 36 and a safety opening 38 in the pillar are aligned with their correspondingly called openings in the plate of hinge 15. A plate of reinforcing nuts 40, preferably laminated from a generally flat metal plate 42 includes first and second sleeves 44 and 46, with rope and with dimensions suitable for receiving the end portions of the bolts 20 and 22. A third rope sleeve 48, extending in the same direction as the sleeves 42 and 44 from the nut plate, is adapted to align with the safety openings 26 and 36 in the hinge and the pillar, respectively, and for receiving in connection an end portion of a security screw 49. A laminated pilot 50, generally cylindrical, extends from a surface of the plate of nuts in an opposite direction to that of the sleeves 44 and 46. For an initial connection to the measurement, the flat extension of the pillar 30 is placed in the nut plate 40 with the opening 38 received in the cylindrical pilot 50 and the openings 32 and 34 aligned approximately with the rope sleeves of the nut plate 44 and 46. A plurality of hot adhesive bodies 52 are located between the pillar and the nut plate and in good contact with both during this time. Next, the articulation plate 15 is mounted on the pilot, and the bolts 20 and 22 and the security screw 49 are screwed lightly in the corresponding sleeves of the nut plate. At this time, the custom-fitting joint is achieved for the door in the space for the body door (not shown) by changing the parts, as necessary, after which the bolts and the screw are tightened. security. The antioxidant treatment (coating E) and subsequent curing processes are carried out, which provides sufficient heat to activate the adhesive bodies and secure the pillar and the nut plate in a precise and predetermined joining arrangement for the body door vehicle. The bolts 20 and 21 are disassembled, allowing the hinged door or hinges to be removed from the vehicle body, to apply accessories (for example, windows, locks, internal leather or fabric garments). After the step of assembling accessories, the door is reassembled on the pillar when bolting the bolts, as described above. Turning now to Figure 3, a second embodiment of the present invention is shown, in which the hinge parts of the pillar and the door for assembling the door assembled are identical to those of the first embodiment, and consequently the pieces are indicated by identical numbers. A fundamental difference is spot welding (i.e., regions 54) of a low carbon steel plate 55 with the pillar 28, where the plate 54 includes apertures 56, 58, 60 and 62 aligned with corresponding pillar apertures. , 36, 36 and 38, instead of using the hot adhesive bodies 52. A nut plate 64 differs from the nut plate 40 described above in that the opening 66 includes a plurality of deformable flanges 68 completely enclosing an enclosed nut 70, providing what is known as a "floating" nut arrangement to which the safety screw 49 is screwed. In addition, the plate 55 includes a hook-shaped flange 72 extending through an opening in the nut plate 64. to secure with one another the plate of nuts, the plate 64 and the pillar. As its name implies, the safety screw 49 in the second mode is held in place when the hinge is removed to mount accessories, in order to maintain the original and precise measurement of the nut plate when they become to apply the bolts. Although the present patent application was described in relation to preferred embodiments, it should be understood that those skilled in the art could contemplate changes, which are within the spirit of the present invention, as described and specified in the appended claims.
