Abstract

Hinge for vehicle doors, comprising two articulated arms, each one of them comprising a blade extending into a neck which ends in a bushing, the blades of said hinge having each one of them at least one hole for the passage of a fixing screw, and the bushings of the two arms being aligned and housing a hinge pin. In one of the arms, at least, the hole of the blade is displaced, with respect to the medium transverse plane of the bushing, in an opposite direction to the other arm, thus the distance between the axes of the blade holes of the two arms being greater than the distance between the medium transverse planes of the bushings of said arms.

Description

Field of the invention

The present invention refers to a hinge for vehicle doors, comprising two articulated arms, one of which is fixed to the body and the other is fixed to the door.
More concretely, the arms of the hinge of the invention comprise, each one, a blade with at least one hole for the passage of fixing screws, from which blade there protrudes a neck which finishes in a cylindrical bushing. The bushings of the two arms are in an aligned position to receive a hinge pin.

Background of the invention

Traditional hinges for mounting vehicle doors correspond to the constitution described, and in each arm the hole of the blade is located in a place coinciding with the medium transverse plane of the corresponding bushing. With this arrangement, the holes of the blades of the hinge arms are separated, in parallel direction to the hinge spin axis, a distance equal to that of the separation between the medium transverse planes of the corresponding bushings.
This circumstance makes the holes of the blades of the two arms close to each other, which limits the choice of screwing-in areas or points of the arms of each hinge. The position of the screwing-in in the door of the arm, or arms, of the hinges would be given by the feasibility of the screwing-in of the arm of the corresponding hinge or hinges in the body, or vice versa.

Description of the invention

The object of the present invention is to solve the problem presented, by means of a hinge which enables to place the screwing-in areas or points of the arms of each hinge, in body and door, independently and thus attain an optimum performance, both in the body and door.
According to the present invention, in one of the arms of the hinge, at least, the hole of the blade is displaced, with respect to the medium transverse plane of the bushing, in an opposite direction to the other arm, thus the distance between the axes of the blade holes of the two arms being greater than the distance between the medium transverse planes of the bushings of said arms.
In this way, there is greater freedom to place the screwing-in points of the hinges, in bodies and doors, and if there were a limitation in the location of said doors in the body, it would enable a greater separation in height for the screwing-in point and door, between the upper and lower hinge, increasing the distance between them and improving the rigidity for the taking down, thus enabling to bear more weight.
The hinge of the invention enables to locate with more tolerance and freedom the mobile arm of the hinge with respect to the fixed arm and its areas or points of fixing to the vehicle frame and doors, which enables to have more freedom for the door design.
In both arms of each hinge the blade hole can be displaced, with respect to the medium transverse plane of the corresponding bushing, in a direction opposite to the other arm.
In traditional hinges for automobile doors, the neck, both of the fixed part and the mobile part, are horizontally located, so that the screwing-in planes in the body and door often approximately coincide in height. In the hinge of the invention, the neck of the fixed part, of the mobile part, or of both, extends in height, and it can have certain inclination to separate, as required by the project, the screwing-in areas or points.

Brief description of the drawings

In the attached drawings there is a non-limiting example of an embodiment, where:

Figure 1 is a perspective view of a hinge for automobile doors, constituted according to the invention.
Figure 2 is a side elevation view of the hinge of figure 1.
Figure 3 shows a frontal elevation view of a hinge constituted according to the invention, once mounted and fixed between an automobile body and door.

The hinge mounted in figures 1 and 2 comprises two arms, indicated in general by numbers 1 and 2, each one of which comprises a blade 3-4 extending into a neck 5-6, which ends in a bushing 7-8.
The bushings 7 and 8 are aligned to receive, through the corresponding drill, a hinge pin 9, as shown in figure 3. Each one of the blades 3 and 4 have, in the example represented in the drawings, a hole 9-10 for the passage of other fixing screws 11, figure 3, to the body 12 and door 13, respectively, of an automobile.
As it can be seen better in figure 2, the hole of at least one of the blades, in the example represented in the drawings of the hole 9 of the blade 3, is displaced, with respect to the medium transverse plane 14 of the corresponding bushing 7 and in a direction parallel to the hinge axis 9 between the two arms, in a direction opposite to the other arm 2. The hole 9 is separated from the medium transverse plane 14 by a distance D, which can be achieved by extending the neck 5 in an inclined position. In this way the holes 9 and 10 of fixation of the two arms are vertically displaced from one another, and thus so are their fixing areas or points to the body 12 and door 13, as shown in figure 3. In this way, the areas of screwing-in to the body and door can be located independently, attaining an optimum performance both in body and door.
The constitution of the hinge of the invention allows more freedom to place the screwing-in points of the arms 1 and 2 of the hinges, both in the body and door. In this way, if there was a limitation for the mounting of the hinge in the body, it would be possible to further separate the screwing-in plane in the door between the upper and lower hinge, increasing the distance between them and thus improving the rigidity for the taking down, which would optimize weight for a performance equal to that of current hinges.
Although in the example described only one of the arms has the condition, or characteristic, of the invention, as it can be understood, both arms of the hinge could have displaced holes 9, with respect to the medium transverse plane of the corresponding bushing, in the way described.
In the hinge of the invention the distance between the holes 9 and 10 of the two blades, measured in the direction of the hinge axis 9 thereof, is greater than the medium distance between the same points of hinge 2.

Claims

Hinge for vehicle doors, comprising two articulated arms, each one of them comprising a blade extending into a neck which ends in a bushing, the blades of said hinge having each one of them at least one hole for the passage of a fixing screw, and the bushings of the two arms being aligned and housing a hinge axis, characterized in that in one of the arms, at least, the hole of the blade is displaced with respect to the medium transverse plane of the bushing, in an opposite direction to the other arm, thus the distance between the axes of the blade holes of the two arms being greater than the distance between the medium transverse planes of the bushings of said arms.
Hinge according to claim 1, characterized in that in the two arms the hole of thy blades is displaced with respect to the medium transverse plane of the corresponding bushing, in an opposite direction to the other arm.
