Description

Hinges for doors with rotary catch (ｈｉｎｇｅ)

Doors that are rotatable often have a swivel catch, which can interfere with the rotatable movement of the door so that it can be held at least in the open position automatically, or the door cannot close itself. It is configured to suppress the free rotation of the door.

Thus, especially in vehicle doors, the doors are constrained in place when the doors are opened to a sufficient size and are configured such that they can be rotated out of restrained state when the pressing force is increased. Often the door has an additional restraint position at a smaller opening angle. When the vehicle is standing on the inclined portion within the limit according to the user specification, the restraining effect is made so that the door cannot move and close itself.

For this purpose, special parts, generally called door arresters, are constructed in the door. The component requires another layout structure with respect to design and manufacture. In particular, when frequent opening and closing is performed, the vehicle door generates considerable wear, and thus the required restraint and braking effects are unclear.

It is disclosed in document DE 44 06 834 C that the function of the component is integrally formed in the hinge of the door. In this case, a hinge pin is provided in the first axial region, a hinge plate is provided which is rotatable in the first axial region, so as to form side wedges which are formed with a plurality of cams having a wedge shape. Protruding structure outwardly or inwardly radially over the cylindrical virtual surface in the upper fin or hinge plate, offset by the same angle in the circumferential direction, and once again forming a sharp taper structure on the cylindrical surface. .

When the side sections are worn, the hinges can be readjusted as long as the disturbing effects of the corresponding side sections are formed by changing the angular positions of the side sections with respect to each other. For this purpose the hinge pins forming the bearing in rotational motion should be rotatable relative to the hinge plate. On the other hand, the hinge pin must be fixed in the hinge plate in such a way that the hinge plate is rotatably fixed so that the hinge plate cannot be accidentally rotated. As a result, disturbance disturbances can be lost.

The present invention is provided in the form of a plurality of cams having a wedge shape and corresponding side cross-sections are provided on the hinge pin and the first hinge plates in the first axial region, the cams on the hinge plate or inside the hinge plate. The cylindrical virtual surfaces protrude beyond the radially inward or outward radial direction, are offset by the same angle in the circumferential direction, form an urgent tapered structure again on the cylindrical surface, and a door with a swivel catch. In particular hinges for vehicle doors.

It is an object of the present invention to provide a simple solution for securing a hinge pin in a hinge plate supporting a hinge pin, by which the fixing position of the hinge pin located in the hinge plate can be changed continuously but at least sensitively. Can, and can reliably, last. This object is achieved by the features described in the characterizing part of the main claim.

In the first embodiment, the side sections of this type can be designed conical, with the axes of the cone lying concentric with the axis of rotation of the hinge. The angular position of the hinge pin located inside the hinge plate can be changed infinitely by the shape of the side cross section. In this case, since only frictional coupling is present, if the moment is unusually high or the fastening action is loosened, the unexpected positional change of the hinge pin located inside the hinge plate is not completely excluded.

Another embodiment is provided for designing the teeth that make the side cross-interfaced such that the hinge pin located within the hinge plate is fully restrained.

Two embodiments shown in the figures are presented as an example of a hinge for a vehicle door. Of course, the invention may be used in hinges for other applications.

The first hinge plate 2 and the second hinge plate 3 connected to each other by the hinge pin 4 are constituted in the hinge 1. The hinge 1 is fixed to the vehicle body of the vehicle on one side of the hinge plates 2 and 3 by screws fixed through the hole 5 and the door is secured on the other side. The hinge pin 4 rotates in the first axial region 6 formed in the hinge plate 2, and the hinge pin 4 in the second axial region 7 formed in the other hinge plate 3. ) Is fixed.

The first axial region 6 formed in the hinge pin 4 and the corresponding bearing hole in the hinge plate 2 is formed in the form of a plurality of cams having a wedge shape and mutually coincident with each other. The cams have end faces 8 and 9, and the cams protrude in the outer radial direction or the inner radial direction beyond the cylindrical virtual surfaces formed on the hinge pin or inside the hinge plate, and are offset by the same angle in the circumferential direction. , It forms a sharp taper structure on the cylindrical surface. When the door is rotated and opened, the angular position of the parts including the side sections 8 and 9 and the upward inclination of the cams so that the surface pressure between the cams which are in sliding motion with respect to each other increases until the rotational movement is disturbed. Are selected. Detailed descriptions and representations of the design and method of operation relating to this type of shaft / hub coupling are described in document DE 42 09 153 C2, mentioned earlier.

The hinge pin is fixed in the hinge plate 2 which interacts with the collar 11 by means of a nut 10 screwed into the end region of the hinge pin 4 made of screws.

In the first embodiment shown in FIG. 1 and according to the present invention, the second axial regions 7 formed in the hinge pin 4 and the side cross sections of the bearing holes located inside the hinge plate 3 are conical. . Since the hinge pin 4 and the hinge plate 3 are connected to each other in a rotatably fixed form, the conical surfaces 12 and 13 can be compressed relative to each other by the fixing screw 14. For clarity, the taper angle is small so that it is exaggerated and sharply shown in the drawings, so that the supporting load associated with rotation under high surface pressure can be increased.

When the door is rotated, the hinge pin 4 is rotated in the hinge plate 2. At the same time, the wedge-shaped surfaces formed on the side sections 8, 9 slide against each other and gradually increase the frictional engagement between the components. As a result, the rotational movement is gradually suppressed. By moving the hinge pin 4 to another starting position in the state where the door is closed, the magnitude of the suppression action can be changed and readjustment is possible in the event of wear.

For this purpose, by loosening the set screw 4, the fit state of the conical surfaces 12, 13 is released and is intended by a tool engaged over the circumference of the collar 11 at the key surface 15. The hinge pin 4 is rotated to the extent that an inhibitory effect is exhibited. In order to ensure the new position of the hinge pin 4, the conical surfaces 12, 13 are pressed against each other in the new mutual position by tightening the set screw 14.

In the embodiment of FIG. 2, the hinge pin 4 inside the hinge plate 3 by means of a nut 17 fastened to the screw at the upper end of the hinge pin and inside the hinge plate 2 by means of a retaining ring 16. ) Is fixed. To ensure the angular position between the hinge plate 3 and the hinge pin 4, the teeth are formed in the upper portion of the second axial region 7 formed in the hinge pin 4 and in the hole formed in the hinge plate 3 inside. A side section of the form (18) is used. The teeth 18 which are in contact with each other are designed as serrations.

In order to change the rotational position of the hinge pin 4 inside the hinge plate 3 after the nut 17 is loosened, the hinge plate 3 is separated from the hinge pin, i.e., the door is lifted. The hinge pin 4 can then be rotated by a tool acting on the key surface 15. When this action is made, the teeth 18 are in contact with each other in another position, and the hinge plate 3 is again placed on the hinge pin 4. Finally, the hinge plate 3 is again fixed on the hinge pin 4 by the nut 17.

Since the teeth 18 have a coupling tolerance, a hinge pin 4 and a hole located in the hinge plate 3 at least on one side are provided in the conical protrusion 19, and the nut (19) is provided by the conical protrusion 19. The components can be fixed relative to each other since 17) is fixed and rattling is prevented. The conical projection 19 adjacent the nut 17 is arranged in a separate projection 20 which can be placed on the hinge pin 4.
