Description

SWIVEL HINGE WITH DOOR LOCK

The present invention relates to a pivot hinge for a vehicle door. Such a pivot hinge usually consists of a door hinge part for attachment to the vehicle door and a body hinge part for attachment to a body pillar.

A pivot mechanism is provided between the door hinge part and the body hinge part, which usually has a single axis of rotation. However, this is not intended to limit the invention to uniaxial swivel mechanisms.

In addition, it is known to snap the vehicle door into a predetermined pivoting position using a door lock. At least in the end region of the possible pivoting movement of the door, the detent track of the door arrester has a detent contour that interacts with a fixedly arranged detent body.

In this respect, it is known to design the door arrester as a detent track which is acted upon by detent bodies and to produce a detent track with detent bodies integrally with the swivel hinge.

For the present invention, it is essentially a matter of this known compact structural unit, which can be manufactured separately and requires only a few hand movements when installed between the vehicle door and the body pillar. It is therefore an object of the present invention to further develop the known swivel hinge between the vehicle door and the body pillar in such a way that, with excellent durability, even heavy vehicle doors can be fitted to the body in a few simple steps.

The invention solves this problem with the features of the main claim. It is essential in this respect that the detent track must either be firmly attached to the door hinge part or to the body hinge part, while the locking bodies located in the locking body holder are then to be arranged accordingly on the body hinge part or door hinge part, so that the swivel hinge together with the door retainer alone by screwing onto the body pillar and vehicle door are mountable.

The compact design of the swivel hinge allows the door arrester to be arranged within the angle spanned by the connecting flanges, e.g. in the form of an annular detent track which extends by approximately 90 degrees and forms a predetermined distance from the pivot axis of the pivot hinge, the pivot body holder also being seated on the corresponding other hinge part within this distance.

This design even makes it possible to apply latching bodies on both sides of the latching track, so that the latching forces present in each case are easily doubled when the latching bodies are immersed in the recesses of the latching track.

For this purpose, it is proposed to arrange the catch rail in relation to the use position of the swivel hinge approximately in the central horizontal plane of the swivel hinge and to preload it with a certain force from both sides Letting catch bodies run on the catch rail, the catch rail on its opposite drain surfaces each having depressions where the opposed catch bodies rest on the catch rail at certain pivoting angles of the door.

The latching bodies are expediently located exactly opposite one another, so that the depressions of the latching track are then also exactly opposite one another. This measure serves to avoid unnecessary bending moments on the rest rail.

Since the effective detent torque depending on the hinge size can also be predetermined in the order of magnitude over the distance of the detent body from the swivel axis of the swivel hinge, high detent forces can be achieved with this compact swivel hinge, so that this swivel hinge is also ideally suited for truck doors.

However, this is not intended to be a limitation of the invention to truck doors, although considerable locking forces are required there.

However, it is a fact that high latching forces can be achieved with the pivot hinge according to the invention, which in particular are able to hold heavy truck doors in any latching position.

For this purpose, it is additionally proposed that the raster track has a plurality of latching contours, which can lie approximately in the swivel range between 30 degrees and 90 degrees.

According to customer requirements, the angular spacing of the locking contours becomes smaller or larger with increasing pivoting angle of the vehicle door in the opening direction.

In addition, the invention offers the advantage of designing the latching body mounts in such a way that they are cold guiding for preload springs, which ultimately act on the locking body and hold it positively and non-positively on the locking track. In addition, it is proposed to make the spring preload changeable via adjusting devices.

In this way, not only can manufacturing inaccuracies be compensated for, but the same pivot hinge is suitable for doors of different dimensions and weights.

For this purpose, it is proposed to form spring assemblies from disc springs, which act on the latching bodies, since disc springs can already apply very high spring forces with short spring travel.

The desired compact design is supported by latching body mounts designed in a housing-like manner, which are essentially vertical in the case of a substantially horizontally oriented latching track and are designed to accommodate the springs / spring assemblies. The housings of the locking body mounts are either designed separately or in one piece with the relevant hinge part of the swivel hinge, while the detent track is attached to the corresponding swivel hinge part. The separate housings can then be attached to the respective hinge part.

The detent track can also be particularly advantageously attached to the relevant door hinge part as a separate component.

To avoid unnecessary wear, the raster track should be overmolded with plastic.

The raster track in turn gives through the locking recesses at its end, ie at the maximum swivel opening angle the vehicle door, practically also the largest possible opening angle of the vehicle door. This is made possible by a corresponding leading edge on the rest rail. On the other hand, however, an emergency stop should also be provided between the door hinge part and the body hinge part, in order to avoid damage to the vehicle door or body if the last catch of the rest rail is exceeded due to overloading.

The preferred arrangement of the latching track and latching bodies in the form of an annular surface of the latching track arranged concentrically around the pivot axis of the pivot hinge requires relatively large contact areas between the latching bodies and the latching track for truncated cone-shaped latching bodies which plunge into correspondingly contoured latching depressions of the latching track. The conical locking bodies with their smaller end faces are oriented towards the swivel axis of the swivel hinge. In any case, the latching bodies are supported on the latching track in a sliding and non-rotating manner. For this purpose, material pairings made of plastics, e.g. Kevlar-reinforced Delrin or polyamide are proposed.

As an alternative to this, the latching bodies can also consist of balls which are immersed in correspondingly contoured ball recesses in the latching track.

The invention is explained in more detail below on the basis of exemplary embodiments.

Show it:

1 shows a first embodiment of the invention, FIG. 2 shows another embodiment of the invention, FIG. 3 shows an embodiment of the invention in a view from above, 4 shows a possible principle for the latching body and the detent track, FIG. 5 shows another possible principle for the latching body and the latching track.

Unless otherwise stated below, the following description always applies to all figures.

The figures show a pivot hinge 1 for a vehicle door 2.

In particular, FIG. 3 shows the details for fastening the swivel hinge 1 to the vehicle door 2. For this purpose, the swivel hinge 1 has a body hinge part 5 which is fastened to a body pillar 3. Furthermore, a door hinge part 4 is provided, which is provided for fastening a vehicle door 2.

A pivot mechanism 6 is provided between the door hinge part 4 and the body hinge part 5, which enables a hinge-like rotary movement between the door 4 and the body hinge part 5.

Here, the pivoting mechanism - without limitation of the invention - is achieved by a pivot axis 7, which sits in corresponding hinge eyes 8 of the door hinge part 4 or 9 of the body hinge part 5 and is fastened in the body hinge part 5 such that the door hinge part 4 rotates about the pivot axis 7 can.

It is essential that the swivel hinge 1 forms a ready-to-install unit with a door lock 10. The door arrester has a detent track 11, which is in a horizontal plane with respect to the pivot axis 7 and has an arcuate design and has one or more detent contours 12. Geometrically adapted latching bodies 14 are to engage in the latching contours, which slide without rotation about their own axis on the latching track. For this purpose, locking body mounts 13 are provided in the movement area covered by the locking track 11, which hold the locking bodies 14.

Detent track 11 and catch body holder 13 are connected to the door hinge part 4 or body hinge part 5 in such a way that the catch track 11 passes the catch body 14 when the door is pivoted 15.

The locking body 14 loads under a predetermined force and positively on the raster track and consequently slides on the raster track 11. It also runs through the locking contours 12 of the detent track, so that when the locking element 14 is immersed in the locking contour 12, a preferred opening position of the vehicle door 2 that is self-centering against low forces is obtained.

As shown in FIG. 3 in particular, both the door hinge part 4 and the body hinge part 5 each have a connecting flange 19 or 20, which connecting flange 19 or 20 is used for fastening to the vehicle door 2 or to the body pillar 3. In the exemplary embodiment shown, the connecting flange 19 is designed as a separate component from the door hinge part 4, which - here - is welded to the door by means of a weld seam 31. The connecting flange 19 has an extension 29 which extends upwards in the installed position and which extends with an eye 30 over the pivot axis 7 and is plugged there onto the projecting pivot axis. The connecting flange is connected to the door hinge part via the screw connection 27. The connecting flanges 19, 20 enclose an angle 21 between them both in the closed position of the vehicle door 2 shown in FIG. 3 and in the open position shown in broken lines.

Essential for the compact design of the pivot hinge 1 is the fact that all components 11; 12; 12 '; 13; 14; 14 'of the door arrester 1 in each angular position of the swivel hinge 1 lie within the angle 21 spanned by the connecting flanges 19, 20, so that the body and door do not require any additional immersion openings for the detent track.

In particular, FIG. 3 shows that the pivot mechanism 6 is at a predetermined distance 22 from the connecting flange 19 of the body hinge part 5. Within this distance 22, the detent track 11 is rotatably guided.

For this purpose - here - the detent track 11 extends in a circular concentric manner around the center of the pivot axis 7 of the pivot hinge 1 and - starting from the pivot axis 7 - faces the connecting flange 20 of the body hinge part 5. Furthermore, the figures show that the detent track 11 has a plurality of detent contours 12, 12 'in the swivel range of the vehicle door 2 between approximately 30 degrees and approximately 90 degrees.

In the present case, according to FIGS. 1 and 2, the locking contours 12, 12 'lie on opposite flat sides of the locking track 11 and are each acted upon by their own locking bodies 14 and 14'.

This design offers the advantage that, in spite of the relatively large distance between the detent track 11 and the pivot axis 7, practically no bending moments are exerted on the detent track 11, since the detent bodies 14, 14 'on both sides with essentially Chen attack equally large forces on the raster track and only generate the latching forces, while they neutralize each other as lateral forces on the raster track 11. In order to ensure a reliable latching function in particular in the case of vehicle doors which move in the end region of their opening angle, the angular spacings of the latching contours 12, 12 ′ are increasingly spaced further apart as the pivoting angle of the vehicle door 2 increases in the opening direction.

However, as FIGS. 1 and 2 show, this can also be provided for the smaller opening angles of the vehicle door 2, as required. According to the invention, the detent track extends over an angular range that is somewhat smaller than the maximum opening angle of the vehicle door 2.

For this purpose, it is proposed that the angular range over which the detent track 11 extends should be less than 90 degrees.

In addition to this, FIGS. 1 and 2 in particular show a development in which the detent track 11 is arranged approximately in the horizontal central plane 23 of the swivel hinge in relation to the installation position of the swivel hinge 1.

In this way, particularly in connection with spring-loaded latching bodies 14, 14 ', spring packs of sufficient strength can be arranged on both sides of the latching track 11.

For this purpose, FIGS. 1 and 2 each show a development in which the latching bodies 14, 14 'are held against the latching track 11 by an upper biasing spring 16 and a lower biasing spring 17, respectively. The biasing springs 16, 17 are resilient in the longitudinal direction and thus enable the latching bodies 14, 14 'to dip into the latching contours 12, 12' without difficulty and - when the door continues to move - can also move out again.

It follows from this that the latching bodies 14, 14 'rest in their associated positive locking zones 18. Within the positive-locking zones 18, each locking body 14, 14 'is in its locking contour 12, 12' within a certain pivoting angle in stable equilibrium, so that the vehicle door 2 is always centered in the relevant open position.

Fig.l and Fig.2 differ in terms of spring types.

In Fig.l a pair of coil springs is shown, which act on the locking body 14, 14 ', while in the case of Fig.2 packets of disc springs are shown.

In comparison to coil springs, disc springs offer the advantage of a significantly higher spring preload even with small spring travel, and the spring constants are also easier to vary.

In addition, FIGS. 1 and 2 show that, regardless of the type of prestressing springs 16, 17, adjusting devices 24 can be provided, by means of which the spring prestress can be adjusted.

It can now be easily imagined that the locking body holder 13 is designed as a locking body housing 25 which, depending on the arrangement, is connected either to the body hinge part 5 or to the door hinge part 4. On the other hand, the catch rail 11 must then in turn be connected to the door hinge part 4 or the body hinge part 5. The locking body housing 25 can preferably also be formed in one piece with the associated hinge part. On the other hand, it is also possible to flange the latching body housing 25 to the associated hinge part as a separate component.

Advantageously, the detent track 11 is also manufactured as a separate component, which can either be attached to the door hinge part 4 or the body hinge part 5.

3 shows in particular an approximately circular sector-shaped separate component which carries the detent track 11 on the outer circumference. The circular sector-shaped component is fastened to the end of the door hinge part 4 pointing away from the swivel mechanism 6 by means of the unspecified screw and is thus forcibly coupled to the movement of the door hinge part 4. In order to avoid unnecessary wear and especially to reduce noise, the raster track 11 can be injection-molded with plastic.

In addition, however, it is also provided that an additional emergency stop 26 is to be attached beyond that latching contour, which is decisive for the largest door opening angle. This emergency stop 26 consists of two corresponding stop surfaces on the door hinge part 4, on the one hand, and on the body shell part 5, on the other hand, and avoids opening the door beyond a critical angle. This measure serves to avoid damage to the door or body. In addition, FIGS. 4 and 5 also show special designs of locking bodies and locking contours.

In the exemplary embodiment in FIG. 4, the latching bodies 14 are formed by balls which dip into latching contours which are designed as ball recesses.

If you want to achieve 2 large contact zones between locking bodies 14 and locking contours 12, in particular for large pretensioning forces in heavy vehicle doors, it is advisable to design the locking bodies 14, 14 'as tapered rollers and the locking contours as corresponding depressions. The tapered rollers and the locking contours are oriented with their smaller end faces in the direction of the pivot axis 7.

The cone angles result from the geometric relationships with regard to the position of the pivot axis 7 and the respective distance which the detent track 11 occupies from the pivot axis 7.

In any case, however, the locking bodies are non-rotating components of sliding pieces 28, which run on the locking track solely by sliding movement. However, the swivel hinge 1 can always and only be assembled as a prefabricated structural unit, while the vehicle door can then simply be hung on the extension 29 on the swivel axis 7 via the eye 30, for example after separate painting.
