Hinge

The invention relates to hinges, and is more particularly concerned with a door hinge for a vehicle. A major advance of the present invention is to allow a hinge plate bziu. a hinge wing at various manufacturing locations on the door and on the body of his vehicle u / can be grounded so that the manufacture and assembly of the vehicle are advantageously facilitated. It is also desirable that the

-Hinge is provided with a locking device, luelcha the door in a position between the open and holds the door in the closed position. A combination option these features are absent from previously proposed hinges. The present invention is impressive to avoid this disadvantage.

A door hinge according to the invention is usually a male one or plug-in hinge wing, which in a common or nut hinge wing can be used appropriately, u / obei optionally one of the hinge wings on the door or can be attached to the structure of a vehicle. The inventive The hinge also has a cylinder fastened to the lYlutter wing and rotatable with it with control surfaces provided on its inner surface as well as a housing attached to the insert wing and movable therewith with a spring and roller device, wherein the cylinder and the housing are coaxial with the hinge axis, and wherein the spring and Uialzen arrangement is a control roller includes those with the door closed, the door open and in an intervening stables each with a control surface in engagement in the housing can be brought.

In a preferred development of the invention, two such control rollers, which are from the hinge axis by means a leaf spring are pressed outwards, as well as

409808/0528

four control surfaces designed as recesses or grooves provided, u / obei each control surface a part-cylindrical Has surface which mates with the cylindrical surface of a roller when the roller with the control surface is engaged.

Preferably two of the recesses or grooves are diametrical arranged opposite on the inner surface of the cylinder. In the intermediate locking position, the third recess is in engagement with a roller, while the fourth Recess is in engagement with the other roller when the door is open and the diametrically opposed to each other Recesses are each engaged with a roller when the door is closed.

In a particularly advantageous embodiment of the invention the lilutter wing has two hinge links, between which a hinge member of the insert wing fits, and the cylinder member is formed with a projection, which engages in a recess on one of the hinge members of the fflutterflügsls, the hinge members being coaxial to the hinge axis.

The ililutter wing and the insert wing preferably have flat, interacting stop surfaces, which are arranged such that they are in contact with the door open

handle stand.

Further advantages and features can be found in the claims and in the following description and drawings, in which the invention is described and illustrated, for example, using a preferred embodiment. Show:

The door hinge shown in the drawings comprises a male, hereinafter referred to as a plug-in wing Hinge wing 1, which is referred to below as a fflutter wing designated female hinge wing 2 fits into it. The insert wing 1 has a single hinge member 13, which between two hinge members 14 of the Hflutterflugis 2 fits «The hinge wings 1 and 2 are on a vehicle door 15 or a vehicle body 16, which is indicated by dashed lines is attached, for example by welding. the

Wings 1 and 2 are with cooperating surfaces Y and X trained, which when open. Door against each other.

The hinge usually has a locking unit, see Fig. 2, which is arranged around the bearing center line Z-Z and a cylindrical control member 4, which by means of a recess 18 in the upper hinge member 14 of the ililutterflugis 2 fitted protrusion. 17 at the head end des IKlutterflugis 2 is attached. The control surface is the inner surface of the cylindrical member 4, which is provided with four grooves or channels G1 * to G4 with a circular segment or has an approximately crescent-shaped cross-section, as shown in FIG. Two reels R1 and R2 are in a housing 3 housed within the cylinder 4. The rollers are arranged diametrically opposite one another and are held in grooves G1 and G2 when the door is closed, see Fig. 5. Leaf springs 7 are arranged between the rollers and in a hole 20 with a square cross-section between an insert 5 of the housing 3 and an end Closing member 8 held in the housing 3.

The housing insert 5 has a square cross section and fits into a square hole 21. of the hinge member 13 of the insert wing 1. A threaded pin or a lYladenschraubs 10 holds the housing insert 5 in its Position. The lower part of the housing 3 and the lower

Tail of the housing insert 5 are cylindrical and rotatably inserted into the upper and lower hinge members 14 of the lYlutterflugis 2. The final link B and the Housing insert 5 are in the housing .3 with the help of Roller pins 9, i.e. smooth slotted pins or split pins attached or secured in the axial direction.

The mode of operation of the hinge according to the invention u / ird described below:

The door 15 is initially closed, and the rollers R1 and R2 are engaged with the grooves G1 and G2. When the door 15 is opened, the nut wings 2 and 4 rotate the cylindrical control member 14 with respect to the insert wing 1, the housing insert 5, the housing 3, the Springs 7 and the Uialzen R1 and R2, these rollers off the grooves G1 and G2 are bent and with the main

tail of the inner cylinder wall of the control member 4 in contact engagement come. In the process, the rollers are forced inward and compress the springs 7. at if the door is opened by 60, a Zuiischen-Arretier- or latching position is reached in which the roller R2 is pressed into the groove G3 by the springs 7, and so does the movement the door brakes.

409808/0528

When the door is opened further, the roller R2 is released from the Groove G3 pushed out, and the roller R1 comes at completely open door with the groove G4 in locking engagement. In this position, the stop surfaces X touch and Y and prevent further opening of the door.

When the door is closed, the sequence of operations described takes place in reverse order.

The assembly of the hinge is advantageously simple in such a way that the hinge member 13 of the insert wing 1 is inserted between the hinge members 14 of the fflutterflugis 2 will. The remaining, previously assembled parts of the hinge are then placed along the hinge axis Z-Z lowered into its correct position, whereupon the thread screw 10 is used to put the housing insert 5 on To attach the hinge member 13 of the insert wing 1.
