Abstract

The invention relates to a door hinge for motor vehicles comprising a door arrester, consisting of two brackets, namely a pillar bracket and a door bracket that are connected to one another in a rotationally articulated manner via a hinge pin. The arrester comprises a detent profiled piece, which consists of recesses and elevations, which is located on one of the two brackets, and with which a detent element engages with the other of the two brackets while being placed under pressure, particularly spring pressure. The detent element executes a relative movement along the detent profiled piece when the door is pivoted and engages in one of the recesses of the detent profiled piece in order to arrest the door during opening or closing. In order to reliably hold the door in intermediate positions or in the end position, the inventive door hinge is characterized in that the detent element consists of a rotor having at least two blades, and the blades form roll pairings with adjacent recesses on the detent profiled piece when the rotor is displaced. In order to arrest the door in predetermined positions, two blades simultaneously engage in adjacent recesses.

The invention relates to a door hinge for motor vehicles with brake, consisting of two consoles, namely

• a pillar console and
• a door console,
• which are pivotally connected to each other via a hinge pin,
• wherein the lock has a recesses and elevations existing latching profile on one of the two consoles,
• with a locking element on the other of the two consoles under pressure in particular under spring pressure is engaged,
• wherein the locking element during pivoting of the door performs a relative movement along the locking profile and
• for locking the door when opening or closing engages in one of the recesses of the locking profile, wherein the locking element consists of a rotor having at least two wings and form the wings when rolling the rotor on the locking profile Wälzpaarungen with adjacent recesses.

In one known from DE 198 11108 door hinge of this type consisting of depressions and elevations locking profile of the fastener is fixed as a driver plate on the hinge pin, which is axially and radially secured in the hinge eye of the door bracket, so that the driver plate the opening and closing movements of the door follows. The engaging with the locking profile under spring pressure latching element is designed as a roller which is rotatably mounted at the free end of the bracket to a fixed to the column console torsion spring and is pressed by the torsion spring to the locking profile. During movements of the door, the drive plate is pivoted by the hinge pin about the axis thereof, wherein the roller rolls on the locking profile of the driver plate and is pressed into the nearest recess of the locking profile when the movement of the door decreases and a desired opening angle of the door corresponding intermediate position or the maximum opening angle of the door corresponding end position should be taken.

This lock has proven itself in practice. However, the determination of the door in the end position or in an intermediate position requires a relatively high spring pressure, so that the roller is pressed securely into the corresponding recess of the locking profile. Corresponding high forces are required to move the door out of the final position or out of an intermediate position, because the pressure of the spring when rolling out of the recess to the rollover of the adjacent survey reinforced. Therefore, the known lock for applying secure holding forces requires relatively strong torsion springs with corresponding space requirements of the other hinge parts, and the wear due to friction is correspondingly high.

From DE 199 63 702 a locking device for hinges is known in which a detent formed as a toothed segment, namely a detent profile, under spring action with a rotatable cam wheel is engaged. In a pivotal movement of the two components which are rotatably connected to each other by the hinge, the cam wheel rolls on the end face of the toothed segment and its cams engage in the spaces between the tooth-like projections of the toothed segment. This results in the rolling of the cam wheel on the toothed segment Wälzpaarungen with the recesses of the toothed segment, wherein always a cam comes with a recess in engagement. Therefore, this locking device is not fundamentally different in its effect from the above-stated lock.

The invention is therefore an object of the invention to provide a door lock, which allows for safe retention of the door in intermediate positions or in the final position less effort and increases the scope for changes and adjustments of the hinge structure.

• zum Feststellen der Tür in vorbestimmten Positionen zwei Flügel gleichzeitig in benachbarte Vertiefungen einrasten.

To solve this problem, the invention proposes that

• to lock the door in predetermined positions, simultaneously engage two wings in adjacent recesses.

The invention is based on the finding that a secure determination of the door in a Intermediate position or is reached in the end position when the locking element is pressed under spring pressure not only in a single recess, but is supported under spring pressure simultaneously in two adjacent recesses. For this purpose, the invention of the previously known locking elements such as the above-mentioned role or as a mere spring clip end with a circular cross-section, which slides along the locking profile, from, and it is instead provided according to the invention, a rotor having at least two wings, which are designed in that, in the case of a relative movement of the latching profile and latching element, when rolling the rotor on the latching profile, they engage in succession with adjacent recesses and, in the intermediate position and in the end position, engage two wings simultaneously in adjacent recesses.

The elevations between the recesses must always be formed in the prior art, namely formed as arcuate as possible, so that the e.g. roll-shaped locking element rolls under spring pressure along the flanks of the elevations along the bottom of the adjacent depression. According to the principle of the invention, the latching element, namely the rotor, usually engages only with the recesses. In this case, the engaging in the recess end of the wing forms a pivot bearing for the rotor so that it performs a pivotal movement about the pivot bearing until the next wing engages with its end in the next recess and so forms the next pivot bearing, etc. Because the rotational movement of the rotor to its central axis superimposed on the aforementioned pivoting movement, the path of the central axis of the rotor consists of adjoining circular path sections.

According to a development, it is provided that the radially outwardly facing wings of the rotor and the recesses of the locking profile are each formed arcuate. In this way, a defined engagement between the wing tips and the recesses of the locking profile is achieved when the relevant wing end in the recess performs a rotational movement, namely, when the rotor is pivoted about this wing end until engagement of the next wing end in the adjacent recess.

For the aforementioned pivot bearing function, it is advantageous if the ends of the blades of the rotor and the depressions of the latching profile correspond in shape to a circular arc portion. Here, the radius of the circular arc sections of the wing end and the recess should be the same as possible. The arcuate portions of the recesses should be semicircular.

The rotor and the blades of the rotor can be formed in various ways. According to a further development, it is therefore provided that the rotor is a hub part for a rotation axis and optionally thereof integrally with the hub part outgoing wing, as in a gear, or alternatively, a hub part comprehensive recording z. B. at least one disc on which are rotatably mounted as a wing rollers or preferably rotatable, which form the circular arc sections for engaging in the recesses of the locking profile, wherein the radius of the circular arc sections, as already mentioned above, should be as equal as possible. In these two preferred embodiments, the invention is by no means limited. The gear-shaped rotor is characterized by a high degree of robustness due to its one-piece design. As rotatable pins or preferably designed as rotatable rollers wings on at least one disc, preferably arranged between two discs, allow a simple production of the rotor. In addition, rotatably arranged rollers can roll more easily on the locking profile and still form the inventively desired stable position of the door in the respective intermediate or final position. In the following, the term "wing" and "wing tail" includes both tooth-shaped arms and their ends as well as the rollers and their outwardly facing portions, without being particularly noted.

Because of the aforementioned movement conditions of the rotor when rolling on the locking profile is provided according to a development of the invention, that the shape and size of the wells and their distance from each other are matched to the number and the formation of the wings of the rotor, that a wing tip and a recess , When they are engaged with each other, each forming a pivot bearing for the rotor, so that the axis of rotation of the rotor when rolling the rotor on the locking profile in each case performs an arcuate preferably circular arc-shaped pivoting movement between two locking positions. In this respect, the engagement of the wing tips in the recesses also forms more pivot bearing pairings instead of rolling pairings.

Preferably, the rotor has two, three or four blades in a symmetrical arrangement, without this being a limitation of the invention is made.

Between the first and the last recess of the locking profile expediently three further recesses are arranged so that two intermediate positions of the rotor in addition to the outer end position and the closed position corresponding to the closed position of the door are possible. Depending on the size of the maximum opening angle of the door and depending on the number of desired locking positions of the door when opening and closing, however, more intermediate positions are readily possible.

To compensate for installation tolerances, the door hinge can be very easily adapted in that the first recess with which a wing of the rotor is engaged when the door is closed, an extension, so that the rotor in the closed position of the door on the so-called o-position of the hinge can be moved out. The o-position of the hinge would correspond to the last detent position, in which the rotor is supported by two wings in the two last recesses of the detent profile with the door closed. However, by a simple extension of the first or last recess, the o-position of the door hinge can be easily "run over", so that, for example, results for the door hinge a position of -5 ° in the closed position of the door. Under these circumstances, a wing end of the rotor would stand in the extension of the first recess, while the adjacent wing of the rotor rests against the first elevation of the locking profile. This position of the rotor can be easily accepted because the door is closed and therefore it does not matter to hold the door in an intermediate position.

Preferably, the locking profile is formed on the inside or on the outside of a bow, which is fixedly connected to one of the two consoles, and the rotor is then designed to pivot with the other console. An arcuate course of the locking profile allows it, that the locking element, namely the rotor, along a corresponding arcuate path, preferably along a circular arc path is moved, whose center is located on the axis of the hinge pin. As a result, developments of the invention are possible, which will be explained.

For the necessary pressure of the rotor to the latching profile is provided according to a development that the rotor is rotatably mounted on a standing in the direction of the locking profile under spring pressure axis. A particularly simple solution for this arises when the spring-loaded axis of rotation is formed at the free end of an arm of a bow spring. When the other arm of the bow spring is attached to the hinge pin, a very simple construction results for a spring-loaded axis of rotation of the rotor. Preferably, the other arm of the bow spring extends through a coaxial bore in the hinge pin, and in this position, the arm of the bow spring in the hinge pin is suitably secured radially and axially. This results in a very space-saving design, in which the bow spring is safely arranged and held without additional space with its other arm in the hinge pin, while the free arm serves as a pivot bearing for the rotor and the spring force of the bow spring the free arm and thus the rotor against presses the locking profile, which is arranged substantially concentric to the hinge axis. Therefore, a further development of the invention is that the free arm of the bow spring presses the rotor under spring tension on the locking profile on the inside or on the outside of the bow.

Thus, the movement of the rotor along the locking profile can follow exactly the pivoting movement of the door, it is expedient that the free arm of the bow spring, on which the rotor is rotatably mounted, is guided without the pivoting movements of the rotor are obstructed. Because during the pivoting movement, the distance between the pivot bearing and the axis of the hinge pin changes constantly. As a development of the invention, therefore, a guide of the free arm of the bow spring is provided in a radial groove of a guide arm, which is fixed to the hinge pin. The guide arm is mitverschwenkt in accordance with the rotation of the hinge pin, wherein it entrains the free arm of the bow spring, which is freely reciprocated in the radial groove of the guide arm according to the arc of arc sections consisting of the axis of rotation of the rotor.

As far as the remaining structure of the door hinge is provided according to a development that the arc, on the inside of the locking profile is formed, a recess of a sheet bounded, which is firmly connected to one of the two consoles, while the pivot bearing of the rotor with the other the two consoles is connected. At this point it is clear that for the invention - an internal toothing comparable - is preferred that the rotor is arranged in a recess of a sheet plate, on one side of which is the arcuate locking profile. It is also possible to let the rotor interact with an external latching profile, for example on the outside of a sheet. For the invention, however, it is preferred that the rotor runs inside. On the one hand thereby the construction of the door hinge is more compact, and on the other hand results in a closed structure of the door hinge in contrast to the prior art, and there is also a better way to use friction-reducing means such as the use of friction-reducing coatings for the rotor blades and at least for the recesses of the locking profile and / or the use of a permanent lubrication, without external interference can be effective.

Whether the locking profile as in the prior art on the hinge pin with the door bracket or vice versa the locking element, so in the present case, the rotor is connected via the hinge pin with the door bracket depends on the design requirements of the particular application. For the invention, as has already been made clear, it is preferred that the detent profile is formed on the inside of a receiving part (eg on the arc of an arcuate plate) fixedly connected to the door console, and that the parts carrying the rotor are fixedly connected to the hinge pin are, which extends in the mounted position of the hinge through the hinge eye of the door bracket, where it is rotatably mounted, and which is secured against rotation and secured against axial displacement in the hinge eye of the column console.

In order to protect the latching profile as well as the latching element and the rest of the particular moving and stressed components of the arrester is preferred that the receiving part (eg sheet plate) is completed at the side adjacent to the door console by a cover plate.

When the hinge eye of the door bracket with the sheet plate is rotatably mounted around the hinge pin on the hinge eye of the column console, it is sufficient if the hinge pin is secured down in the axial direction by a clamp.

If the advantages of the compact design of the door hinge and also the possibilities of a relatively closed construction by an internal arrangement of the rotor z. B. used in the recess of a sheet plate, it is particularly advantageous if the components forming the lock, in particular the locking profile and the rotor and the pressing or spring device are covered with a protective cap. Because in this case results not only a very compact but also a largely closed design of the door hinge. This results primarily in a number of advantages for the function of the arrester as well as in use, because door hinges with lock usually, as the prior art shows are exposed to contamination and at the same time the risk of touching dirty hinge parts by hand or with garments or the like exists. The protective cap preferably corresponds in cross section substantially to the contour profile of the arch plate of the arrester, so that the protective cap does not take up more space than necessary and also results in an appealing design. In addition, this results in a slight attachment of the protective cap directly to the sheet plate, e.g. by resilient engagement of the protective cap edge below the sheet plate.

The door hinge should be divisible for mounting the door. For this purpose, it is preferred that the hinge pin in the preassembled position of the door hinge with the hinge eye of the respective console - preferably the door bracket - is secured by a pin which engages through the hinge eye into an opening, in particular into a groove on the circumference of the hinge pin.

According to a development of the invention it is provided that a rotatably mounted at the free end of the bow spring annular roller or a wheel with a corresponding formed on the inside of the sheet plate latching profile is engaged as a rotor.

For the application of the invention to the so-called "unitary hinge", for which in the initially considered DE 198 11 108 an embodiment is to achieve a most extensive retention of the basic structure of this type of hinge proposed in a development that the sheet plate with at the Outside of the arc arranged recesses of the locking profile rotationally fixed to the hinge pin and this on the one hand rotationally fixed to the hinge eye the door panel and on the other hand rotatably disposed in the hinge eye of the column console.

In particular, for this embodiment according to the invention it is provided that extends the free rotatably supporting the rotor arm of the bow spring below the column console and continues in a preferably double U-shaped bent spring member which is fixed to the wing of the column console. The rotor is preferably rotatably mounted at the upper free end of the free arm of the stirrup or torsion spring and resiliently pressed against the locking profile.

For a safe axial guidance of the rotor to the sheet plate when the sheet plate moves along during the pivoting of the door on the sheet plate, it is preferably provided that above and / or below the rotor, a disc is rotatably mounted, which engages over the sheet plate partially. Preferable is a rotor with two discs, especially when the blades of the rotor are formed from rollers.

In the case of the formation of the wings of the rotor with rollers bearing journals are suitably mounted as a pivot bearing for the rollers between two discs.

In Figure 1-3, a door hinge with lock a door bracket 1 with a wing 1a for attachment to a partially shown in Figure 2 door frame T of a motor vehicle and a pillar bracket 2 having a wing 2a for attachment to a partially illustrated frame R, the frame opening being opened and closed by pivoting the door. Usually two door hinges are arranged one above the other at a distance. It is sufficient if one of the two hinges is equipped with a door arrester as in the case of the embodiments of the present invention and the other hinge assumes only a supporting and pivoting function. The door lock according to the invention is, as will become clear, provided for locking the door in an end position and in a plurality of intermediate positions.

On a hinge eye 2b of the column console 2, a hinge eye 1b of the door bracket 1 is rotatably mounted about a hinge pin 3. For this purpose, the hinge pin 3 is arranged on a paragraph 2c in a bore of the hinge eye 2b by means of a flattening 3a rotationally fixed. The hinge eye 1b of the door bracket 1 is rotatable relative to the hinge pin 3 about a rotation axis 27. In a corresponding bore of the hinge eye 1b of the door bracket 1 is a radial bearing 14, and between the two hinge eyes 1b and 2b, a thrust bearing 13 is provided.

As shown in particular Figure 1, the hinge pin 3 extends through a guide arm 8 which is connected by a shoulder 10 rotationally fixed to the hinge pin 3, further by serving as a receiving part sheet plate 4, relative to the hinge pin 3 is relatively rotatable, then by a with the sheet plate 4 fixedly connected cover plate 7, against which the hinge pin 3 is also relatively rotatable, and by the two hinge eyes 1b, 2b. In a corresponding groove 11a near the hinge eye 2b and in a groove 12a near the guide arm 8 are respectively terminals 11, 12 provided as external axial securing the position of the hinge pin 3 and the cohesion of the aforementioned components.

Through the hinge pin 3 extends coaxially in the longitudinal direction of a bore 3b, in which an arm 19 of a bow spring 17 is arranged and secured by suitable means such as a narrowest possible fit and / or a positive locking such as tongue and groove or the like against axial and radial displacements , At the end of the hinge pin 3 protruding under the hinge eye 2b, a corresponding deformation of this end results in a constriction of the arm 19 of the bow spring 17 an axial fuse 20 made.

A transversely to the longitudinal axis of the hinge pin 3 in the hinge eye 1b insertable pin 15 engages in a groove 16 on the hinge pin 3 for securing the door hinge in the preassembled state.

The arch plate 4 has for the formation of a door arrester a recess 5 in the apparent in particular from Figure 2 shape and position, which is bounded on one side by a sheet 6. On the inside of the sheet 6, a locking profile 21 extends consisting of approximately semicircular depressions 22, between which relatively flat elevations 23 are located.

At the end of the free arm 18 of the bow spring 17, as can be seen in particular Figure 1 in conjunction with Figure 2, a rotation axis 26 is formed on which a rotor 24 is rotatably mounted, the three wings 25 in a symmetrical arrangement, as shown in Drawing can be seen, having semicircular wing tips whose radius substantially corresponds to the semicircular arc of the recesses 22.

As can be seen from Figure 1, the door hinge on the side at which the door lock is located, covered with a protective cap 11b, which corresponds in cross section substantially the outline shape of the sheet plate 4 (see Figure 2) and preferably resiliently under the Arch plate 4 is clamped clamped on the door hinge. While all components of the door hinge described so far consist of steel or sheet steel, the protective cap 11b can either be molded from plastic or manufactured by deep drawing of sheet steel.

The rotor 24 forms with the wings 25 a latching element, which under spring pressure perform a relative movement along the locking profile 21, namely can roll on this, and is pressed by the bow spring 17 against the locking profile 21. When pivoting the door is a rotational movement of the door-side hinge parts, namely the door bracket 1 with the wing 1a, the hinge eye 1b and the Feststellerbauteilen as especially the sheet 4 to the fixed to the column bracket 2 hinge pin 3 instead. Also, the bow spring 17 and its free arm 18 with the rotor 24 are fixed and not mitverschwenkt accordingly (see Figures 5 and 6). This fixed bearing is supported by the guide arm 8, in whose slot or groove 9, the free arm 18 and in particular its end with the axis of rotation 26 of the rotor 24 can reciprocate when the sheet plate 4 is pivoted to the door hinge and the rotor 24 is rolled on the passing Rastprofile 21. Thus, the free arm 18 of the bow spring 17 presses the rotor 24 in each angular position of the door hinge against the latching profile 21. The rolling of the rotor 24 on the latching profile 21 takes place - viewed from the axis of rotation 26 of the rotor 24 - along one of adjacent semi-circles formed path (see Figure 3), so that the axis of rotation 26 of the rotor 24 constantly changes its distance from the axis of rotation 27 during a pivoting movement and this corresponding evasive movements of the axis of rotation 26 in the groove 9 are required.

The rolling motion of the rotor 24 relative to the latching profile 21 is such that, when a wing 25 of the rotor 24 with its semicircular end with one of the recesses 22 is engaged, the rotor 24 has a pivoting movement about this of the respective recess 22 and the so that engages wing 25 formed pivot bearing executes until the next wing 25 comes into engagement with the next recess 22 and thus a new pivot bearing is formed, which replaces the previous one. In this respect, the rotor 24 comes only with the recesses 22 into engagement. In any case, only the recesses 22 are needed for the rolling motion of the rotor 24. An exception is the first elevation 23 located on the right-hand side with reference to FIG. 2, which can engage a wing 25 due to an extension 22a of the first recess 22 for reasons which will be explained below (compare FIGS. 4 and 8). ,

In the embodiment of Figure 2, the rotor 24 can take on the locking profile 21 a total of four locking positions. The first detent position corresponds to the end position shown in Figure 2 in the closed position of the door. The second detent position corresponds to a first intermediate position of the door, in which two wings 25 of the rotor 24 are arranged in the second and third recesses 22 (seen from right to left in FIG. 2) (similar to FIG. 5). Accordingly, after a further pivotal movement of the rotor 24, two wings 25 of the rotor 24 in the third and fourth recess 22 (similar to Figure 6), so that the rotor 24 thus assumes a second intermediate position. After the last pivoting movement, the rotor 24 assumes its outermost position and detent position, in the two of its wings 25 are in the fourth and fifth or last recess 22 and the door is fully open.

If the door is brought out of the closed position in the outermost opening position, the locking profile 21 passes over the two intermediate positions, and the rotor 24 passes directly into the outermost locking position. If the door movement is delayed when opening or closing in the vicinity of an intermediate position, the free arm 18 of the bow spring 17 pushes the rotor 24 into the relevant defined intermediate position, in which the corresponding ends of two adjacent wings 25 are arranged in the associated recesses 22.

In this position and also in any other intermediate position or in the outermost detent position, the rotor 24 is always supported under spring pressure in two recesses 22, so that the door is held securely with a comparatively low spring force in this position. Nevertheless, this locking force can be overcome by re-moving the door to pivot the same without problems.

A particularly smooth operation of the fastener is obtained when the rotor 24 and the locking profile 21 receive a friction-reducing coating and / or a permanent lubrication. The latter is - in contrast to the prior art - in door hinges readily considered, because door hinges are preferably encapsulated, i. the lock is arranged inside the door hinge and additionally protected by the cap 11 b and secured against contact.

In Figure 3, an embodiment of the invention with a lock is shown, which allows except the illustrated detent position in the closed position of the door and the outer latching position with fully open door (opening angle about 70 °) an intermediate position of about 35 °. The direction of the pivoting movement of the door and thus of the wing 1a of the door bracket 1 is indicated in Figure 3 with an arrow 30.

FIG. 4 shows a detail of the arrester of FIG. 3 for explaining how assembly inaccuracies, deviations in the given manufacturing dimensions and stresses can be eliminated or compensated in the exemplary embodiments of the invention. The rotor 24 of the arrester is in Figure 4 in its first position, namely in the closed position of the door. The o ° position of the rotor 24 corresponds to the predetermined ideal position of the rotor 24 on the latching profile 21, namely, when two wings 25 are in the first and second recess 22 in the closed position of the door. Through the extension 22a of the first recess 22, the rotor 24, as indicated by the angle -2 °, -5 ° and shown, run over the o ° position until the door has actually reached its closed position in this tolerance angle range of the door hinge.

In Figure 5 is shown which position the rotor 24 occupies the latching profile 21 of the arrester of Figure 3, when the door is half open and the wing 1a of the door bracket 1 assumes a position corresponding to an opening angle of the door of 40 °. In the illustration of Figure 6, the position is shown, which corresponds to the maximum opening angle of the door of 75 °.

The embodiment of Figure 7 shows a lock with four possible locking positions, namely the two outer positions and two intermediate positions with the same or symmetrical angle amounts between the positions. In contrast, in Figure 8, a lock with partially symmetrical angle sections between the individual positions is shown, while Figure 9 shows an asymmetrical distribution of the angular amounts in one embodiment of a fastener with only one intermediate position.

The embodiment of Figure 10 differs from the previous embodiments, especially in that the rotor 24 has not three but only two wings. Moreover, there are no significant differences from the previous embodiments with regard to the structure and function of this door hinge. The arcuate plate 4 with the recess 5 has a rather square outline with rounded corners compared to the embodiments described above and shown in the drawings, and the arc 6 carrying on its inner side the locking profile 21 is correspondingly shorter than in the other embodiments. For the two-bladed embodiment of the rotor 24, the illustrated boomerang-like shape is preferred over the star shape of the three-bladed rotors 24. As a result, the rotor 24 is supported in the closed position of the door, as shown, with its back at a contact point 31 of the latching profile 21. Accordingly, there is a support at a second contact point 32 in the fully open position of the door T. Between these two positions is a Dashed position shown intermediate position possible. When opening the door, the sheet plate 4 is pivoted to the wing 1a of the door hinge 1, the two-bladed rotor 24, as shown in phantom, on the locking profile 21 with corresponding engagement positions between the wings 25 and the corresponding semi-circular recesses 22 from. It is also possible to drive over the 0 ° position because play is provided on the wing side, which is opposite the wing 25 in engagement with the last recess 22. Moreover, the representation in conjunction with the components provided with the same designations as in the previous embodiments gives an understanding of the structure and function of this simplified embodiment.

In Figure 11, a door hinge of the type of Figure 1 is shown prior to assembly, wherein it is clear that the door hinge is pre-assembled on the door frame T ready for assembly and for final assembly by inserting the hinge pin 3 in the hinge eye 2b of the column console. 2 on the frame R and secure the hinge in this position with the clamp 11.

The embodiment shown in Figure 12-14 of a door hinge, which corresponds to the basic structure of the so-called. "Unit hinge", the sheet plate 4 is fixed with the arranged on its outer side latching profile 21 at the bottom of the hinge pin 3. For this purpose, a trained at the lower end of the hinge pin 3 polygonal profile 36 extends through a corresponding internal polygonal profile 37 of the sheet plate 4. Moreover, the hinge pin 3 is rotatably mounted in the hinge eye 2b of the wing 2a of the column bracket 2 with the bearing sleeve 35 and at its upper end , as the drawing shows, positively arranged rotationally fixed in the hinge eye 1b of the door bracket 1 and fastened by means of a clamping screw 39. The lower end of the hinge pin 3 below the sheet plate 4 and a closure plate 38 in the usual manner by means of a lock nut or a lock screw (not shown). As is apparent from FIG. 14, the sheet plate 4 can optionally be arranged in a segment-shaped protective housing 40. The bow spring 17 is otherwise fixed in the usual manner with a double U-shaped curve, as shown in Figure 12 and 13, on the wing 2a of the column bracket 2.

In the lower part of the exploded view of Figure 14, there are two In the left part of the drawing in the drawing, a gear-shaped rotor body with four wings 25 is shown to form a rotor 24 which is mounted between two discs 33 and rotatable on the axis of rotation 26 at the end of the free arm 18 of Bail spring 17 is mounted. Alternatively, four rollers 25a are shown as wings in the drawing part located to the right thereof and mounted rotatably by means of bearing journals 34 between two discs 33. The thus formed rotor 24 is rotatably mounted with a bearing sleeve 35a on the end of the free arm 18 of the bow spring. The bearing pins 34 are in the present embodiment, each of sleeves 41 and pins 42. However, the bearing pins 34 may also be integrally formed and so be connected to form a cage-shaped rotor 24 with the two discs 33 and the rollers 25a. In each of the two embodiments, a central hub portion 24a is provided for the rotatable mounting of the rotor 24.

In both embodiments, usually two, three or, as shown, four wings 25 or 25a for the formation of the rotor 24 from. The use of a larger number of blades 25 or rollers 25a is readily possible, if necessary. This also applies to the embodiments explained below.

The operation of the embodiments of door hinges with lock shown in Figures 12-14 results readily from the foregoing description of the operation of the other embodiments. This means that the rotor 24 is resiliently pressed against the locking profile 21 of the sheet plate 4 and two wings 25 and rollers 25a engage in the arcuate recesses 22 of the locking profile 21 when the door is pivoted and stopped in an intermediate or final position. A further explanation of the structure and the operation of this embodiment is unnecessary due to the drawings, which can be easily seen the structure and operation of this hinge door type.

The exemplary embodiment illustrated in FIGS. 15-18 supplements the embodiments according to FIGS. 12-14 by depicting a motor vehicle hinge of the "unitary hinge" type with door stop. The basic hinge structure is readily apparent from the drawing, where appropriate, taking into account the explanations to the figures 12-14, refer to, so that the repetition of a description of this part is omitted.

In the region of the door arrester, as illustrated in FIGS. 15-18, at the end of the free arm 18 of the bow spring 17, an axis of rotation 26 is also formed in this case, on which the gear-shaped rotor 24 is rotatably supported by means of a bush 26b. The rotor 24 has a hub portion 24a and four outgoing therefrom in cross-section circular wings 25 in a symmetrical arrangement with arcuate preferably semicircular wing tips whose radius corresponds substantially to the arc of the recesses 22 of the locking profile 21.

The rotor 24 has on its underside a disc 33 which is integrally formed with the rotor 24 and the arc plate 4 engages under the rotor 24 abuts against the locking profile 21, as shown in particular Fig. 18 shows. Above the rotor 24 and the bush 26b sits a stop roller 26a on the axis of rotation 26 below the hinge eye 2b (Fig. 15), so that it is already axially secured by this arrangement. However, it can also be attached directly to the end of the axis of rotation 26.

The rotor 24 forms with the wings 25 a latching element, which under spring pressure perform a relative movement along the latching profile 21, namely, can roll on this, and is pressed by the bow spring 17 against the locking profile 21 (Figs 17 and 18). As has already been explained to the embodiments described above, takes place when pivoting the door, a rotational movement of the door-side hinge parts, namely the door bracket 1 with the wing 1a, the hinge eye 1b and Feststellerbauteilen as especially the sheet plate 4 with the hinge pin 3. The bow spring 17 and its free arm 18 with the rotor 24 are fixed and are not mitverschwenkt accordingly.

The sheet plate 4 is pivoted to the door bracket 1, wherein the rotor 24 on the itself passing by latching profile 21 is rolled off. Thus, the free arm 18 of the bow spring 17 presses the rotor 24 in each angular position of the door hinge against the latching profile 21. The rolling of the rotor 24 on the latching profile 21 takes place - viewed from the axis of rotation 26 of the rotor 24 along one of adjacent semi-circles 3), so that the axis of rotation 26 of the rotor 24 constantly changes its distance relative to the axis of rotation 27 during a pivoting movement and corresponding deflection movements of the axis of rotation 26 take place for this purpose.

The rolling motion of the rotor 24 to the latching profile 21 is such that when a vane 25 of the rotor 24 with its semicircular end with one of the recesses 22 is engaged, the rotor 24 is a pivoting movement about this of the respective recess 22 and the thus engaged wing 25 formed pivot bearing performs until the next wing 25 engages with the next recess 22 and thus a new pivot bearing is formed, which replaces the previous one. As such, the rotor 24 primarily engages the recesses 22. In any case, only the recesses 22 are needed for the rolling movements of the rotor 24, in pairs for each locking position.

As a precaution, reference is already made to Fig. 36, where it is shown that the rolling motion of the rotor 24 does not necessarily require semicircular ends of the vanes 25 of the rotor 24 and approximately arcuate or even semi-circular depressions 22, but the movement of the rotor 24 along the locking profile 21 as well as the support of the rotor 24 with two wings 25 in adjacent wells 22 also readily with flat surfaces on the end faces of the wings 25 and the recesses 22 is possible.

In the example according to FIGS. 15-18, the rotor 24 can assume a total of three detent positions on the detent profile 21. The first detent position corresponds to the end position in the closed position of the door. The second detent position corresponds to an intermediate position of the door, in which two wings 25 of the rotor 24 are arranged in the second and third recesses 22, viewed from right to left. After the last pivoting movement, the rotor 24 assumes its outermost position and detent position in which two of its wings 25 are in the third and fourth and last recess 22, respectively, and fully open the door is.

If the door is immediately brought out of the closed position into the outermost opening position, the latching profile 21 passes over the intermediate position, and the rotor 24 immediately reaches the outermost locking position. If the door movement is delayed when opening or closing in the vicinity of the intermediate position, the free arm 18 of the bow spring 17 pushes the rotor 24 into the relevant defined intermediate position, in which the corresponding ends of two adjacent wings 25 are arranged in the associated recesses 22 and support it there.

According to a development of the invention, the wings 25, as well as Fig. 18 shows, a height which is greater than the thickness of the sheet plate 4, at least in the region of the locking profile 21. By this measure, the sheet plate 4 always carries on full width or Height, and the same applies to the wings 25 of the rotor 24, so that the wear is as low as possible.

In this position and also in the outermost locking positions, the rotor 24 is always supported under spring pressure in two recesses 22, so that the door is held securely with a comparatively low spring force in this position. Nevertheless, this locking force can be overcome by re-moving the door to pivot the same without problems.

In the embodiment of FIGS. 19 and 20, a further possibility of the bearing of the rotor 24 on the end of the free arm 18 of the bow spring 17, namely on the axis 26, shown by a shoulder 18 a of the free arm 18 of the bow spring 17th is divided. For this purpose, a bearing bush 26b is pressed into a bore 24b of the hub portion 24a of the rotor 24, which forms a sliding bearing with the axis 26. For the axial bearing of the rotor 24, a ring made of a bearing material can be arranged on the shoulder 18a.

In particular, from Fig. 20 shows and is considered as a possibility for all other embodiments, namely that the rotor 24 below final and designed with this expedient as a sintered molded part disc 33, wherein rotor 24 and disc 33 are optionally cured or surface hardened, not necessarily a circular outer contour must have, as for example. Fig. 16 and 18 can be seen. Rather, it is sintering technology easier to choose a disc shape as shown in Fig. 20 type with protrusions 33a and recesses 33b. Sufficient bridges continue to exist between adjacent vanes 25 and beyond, which reinforce and protect vanes 25 at the bottom. They also form a guide of the rotor 24 to the locking profile 21 of the sheet plate 4, the z. B. Fig. 15-18 can be seen.

Finally, this embodiment also makes clear that the wings need not be evenly distributed on the circumference of the rotor 24. Rather, it is sufficient to form wings 25 over a sufficiently large arcuate portion of the rotor 24 to ensure that there are always a sufficient number of pairs of wings 25 for the desired locking positions including the closed position of the door available.

In FIGS. 21-27, three further embodiments of rotary bearings of the rotor 24 are shown on the axis of rotation 26 of the free arm 18 of the bow spring 17.

In Fig. 21 and 22, a pendulum bearing is shown, which allows the rotor 24 in addition to the rotational movement about the axis 26 oscillations with respect to the axis of rotation 26a. Because the free arm 18 of the bow spring 17 is, as already stated above, subjected to angular deviations when the free arm 18 during the movement of the rotor 24 along the locking profile 21 back and forth, so that the rotor 24 is always in contact with the locking profile 21 remains. Also from the existing of adjacent arches path of the axis 26 in Fig. 3 inevitably corresponding movements of the axis 26 with angular deviations with respect to the parallel position of the axis 26a relative to the long center leg of the bow spring 17. Such angular deviations compensates the pendulum bearing, so that the rotor 24 maintained its axis-parallel position relative to the sheet plate 4 and the peripheral surface of the wings 25 can follow the course of the locking profile 21 without tilting.

For this purpose, a press-fitted on the rotation axis 26 in cross-section spherical bearing ring 43 cooperates with a pressed into the bore 24b of the rotor 24 to a paragraph 45 sleeve 44 with correspondingly hollow storage surface. The wear-subject Components of this storage are - as well as the bearings described below - expedient at least surface hardened.

The representation of the rotor 24 in Fig. 22 in comparison to the representation of the rotor 24 in Fig. 23 makes it clear again that - regardless of the type of bearing of the rotor 24 - the shape of the rotor 24 both in terms of number, distribution and arrangement of the wings 25 as well as with respect to the shape of the rotor body made of one piece sintered material disc 33 may well - also as far as the supernatant of the projections 33 a of the disc 33 with respect to the arcuate portion of the wings 25. Basically supports, connects and reinforces the disc 33 with the projections 33 a, the wings 25 and forms a guide for this purpose on the arch plate 4th

Also, the embodiment of FIG. 24 and 25 shows a pendulum bearing. However, here in contrast to the embodiment shown in FIG. 21 and 22, a stepped intermediate ring 46 is pressed into the rotor 24, the upper ring inner surface in cross section corresponding arcuately extending to form corresponding bearing surfaces with the crowned in cross-section bearing ring 43, as in the previous example is pressed onto the axis of rotation 26. Not clearly discernible in the drawing is a slight play of the axis of rotation 26 relative to the upper opening in the hub of the rotor 24 and the intermediate ring 46. This clearance allows the rotor 24 to oscillate about 2-3 ° to avoid tilting of the rotor 24 against the locking profile 21, as already stated above.

In the further embodiment according to FIGS. 26 and 27, the rotor 24 is mounted with a needle bearing 48 with the interposition of a sleeve 47, as can be seen from the drawing, on the axis of rotation 26 of the free arm 18 of the bow spring 17.

When using a needle bearing while no angle compensation as in the pendulum storage is possible. However, pivotal mounting is generally improved and uniform torque is transmitted over a very long period of time. This extends the life. In the pendulum bearing, the bearing content is improved by avoiding edge run. This results in less inlet or less wear, and the plain bearing bush used has improved sliding properties over a direct engagement between the axis of rotation 26 and the rotor 24. It goes without saying that for the self-aligning spherical plain bearings of any kind with spherical cross-sectional shape - convex as well as concave - into consideration.

In the further embodiment of the invention according to FIG. 28-35 a particularly robust, trouble-free - working even at high load cycle number- working design of the rotor 24 is shown with a long service life, which cooperates with a sheet plate 4 of a very simple design, as the drawing shows.

The general structure of the hinge, to which this embodiment is applied as an example, already goes from previously described figures such. As Figs. 12, 13 and 15 and therefore will not be repeated here again. The same reference numerals as in the previously mentioned figures are sufficient for understanding the general structure of the hinge according to FIGS. 28-31.

The structure and the bearing of the rotor 24 forms the peculiarity of this embodiment. From an upper and a lower plate 33 preferably formed as a stamped part or from sintered material and each with a central bore 50 and four arranged in a uniform and symmetrical arrangement around the central bore 50 receiving openings is by means of four in the center part crowned pin 49 a compact cage as a rotor 24 produced. Each pin 49 is preferably hardened at least at the middle part on the surface or as a whole and has at both ends in each case via a shoulder 55 against the pin 49 recessed shaft 53. Each pin 49 engages with its upper and lower shank 53 in corresponding receiving openings 54 of the upper and lower disc 33. The protruding ends of the shafts 53 are then deformed to rivet heads 52, so that a total of highly stable rotor body arise. A bearing sleeve 51 is pressed into the central bore 50 and forms with the axis of rotation 26 of the free arm 18 of the bow spring 17 is a pivot bearing for the rotor 25th

The individual components of the rotor 24 are shown in FIG. 32 and the ready-made rotor 24 mounted on the axis of rotation 26 can only be seen with adjacent components 33-35 and in the hinge itself FIGS. 28-31.

When the rotor 24 is in engagement with the driver plate 4 (FIG. 35 and also FIGS. 28-30), the crowned pins 49 engage with the depressions 22 and the elevations 23 of the latching profile 21, whereby in latching positions of the door arrester two Support pin 49 in two adjacent recesses 22 of the locking profile 21. The upper and the lower disc 33 take a safe leadership and contact of the rotor 24 with the sheet plate 4. The spherical shape of the pin 49 undesirable effects are avoided, which is characterized by edge pressures at angular changes of the rotor 24 relative to the locking profile 21 of the sheet plate can result.

Fig. 28 and 29 show the position of the hinge and thus also the door arrester and thus also the rotor 24 at one end of the locking profile 21 on the sheet plate 4. This position results z. B. for a left rear door hinge of a motor vehicle with the door closed. When you open the door z. Example, the intermediate latching position shown in Fig. 30 and 31, when the door is stopped in the half-open position.

Fig. 36 shows that the ends of the wings 25 of the rotor 24 as well as the recesses 22 of the locking profile 21 and its elevations 23 by no means necessarily arcuate or arcuate segment-shaped as in the previously described and illustrated in the drawings embodiments. In Fig. 36 wings 25 are shown with flat and mutually parallel flanks and conical recesses 22 of the locking profile 21 of planar sections. The end faces of the wings 25 of the rotor 24 are also flat or spherical, as shown in dashed lines. The dashed lines with arc shape illustrate the trajectory of the central axis 26a of the rotor 24 on its way along the locking profile 21st
