Description

DETAILED DESCRIPTION OF THE INVENTION Removable door hinges are used in modern mass production of automobiles for the purpose of fitting and adjusting the door to the vehicle body during the rough assembly of the automobile, and then , to be able to be removed from the vehicle body during assembly and outfitting of the vehicle, and this is accomplished in the following manner. That is, both parts of the hinge are respectively attached to the door locating member, i.e. the door or the door mounting spar, and are immovably fixed;
In this way, when the door is refitted into the car body, the door is fitted in exactly the same way as the notch in the car body into which the door fits.
This allows the assembly and outfitting of automobiles to
The benefit of removing the door is that it can be done faster and more easily.

Removable door hinges for house doors or furniture doors are already known, in which the hinge axis is non-rotatable to a hinge member that can be fixed to the door arrangement member, i.e. the door mounting frame. A cylinder into which the hinge shaft can be inserted is connected to another hinge member. However, door hinges for houses or furniture are not comparable to door hinges for automobile doors. This is because the hinges of doors of houses or furniture are initially subjected to only small loads and, moreover, are operated under environmental conditions that are virtually always kept the same, so large tolerances are allowed. And simple manufacturing methods are becoming possible.

The object of the invention is to create a removable door hinge of the above-mentioned configuration for a motor vehicle door, which hinge can be used with as little manufacturing and assembly costs as possible. Thus, while automatically compensating for mating errors, it is possible to ensure that vehicle doors that have been adjusted once during the rough assembly of the vehicle body will be able to maintain the original position from which these doors were adjusted, even during a subsequent second assembly. position, the hinge does not require any special labor costs or special technical equipment for this installation, and the hinge can nevertheless be removed inadvertently over the range of its swivel use. It is something that never happens.

The above objects are achieved by the present invention as follows. This is achieved in that at least part of the length of the hinge shaft is non-rotatably connected to the hinge hole into which it can be inserted via a molded part formed in a form-locking manner. In this case, at least the cross-section of the hinge shaft should have an abutment surface oblique to the hinge shaft that matches the cross-section of the hinge hole of the other hinge wing. In removable door hinges such as those described above, the half of the hinge supporting the hinge shaft is fixed to the door positioning member, in particular by welding, so that the door does not move into a position corresponding to the adjusted position.
In particular, the hinge axis is fastened to the door frame and at the same time the other half of the hinge is fixedly fixed as before to another door positioning member, thus corresponding to the adjusted position of the motor vehicle door. The position can already be immovably fixed during rough assembly of the motor vehicle body. Taking into account the large hinge loads assumed for automobile door hinges, the hinge shaft is supported by sliding seats in the hinge halves in an initially and precisely adjusted position, while the hinge shaft cooperates in a form-locking manner with the other half of the insertable hinge.

The invention can be realized in different ways, in which case the hinge axis and the hinge hole of the other half of the hinge are arranged alternately in the radial direction over at least a part of their length. It has a protruding portion and a recessed portion that engage with each other. In the simplest case, the radially protruding and recessed parts, which are arranged alternately and interlock with each other when the door is installed, are located in the horizontal plane and protrude from the hinge holes in the hinge halves of the hinge axis. placed at any position along the long section.

According to a first embodiment of the invention, the hinge shaft rotatably supported in the hinge half projects radially and has a shaft zone portion extending beyond the upper front face of the hinge hole of the hinge half. The upper surface of this shaft band portion is provided with radially oriented striations and grooves or protrusions and recessed portions, which also have radially oriented striations or groove moldings on the other side of the hinge. It is attached to the front of the half hinge hole. In this case, the striation or groove molding part on the upper surface of the shaft band part of the hinge shaft is formed in the shape of a conical gear, and the striation or groove molding part on the front surface of the hinge hole of another hinge wing is correspondingly inclined in the opposite direction. It is particularly advantageous for the shank portion of the hinge shaft as well as the radially oriented striations or grooves of the front face of the hinge hole or the flanks of the protruding or recessed portions to be formed with respect to each other. It is particularly advantageous if the two parts are arranged at an acute angle. The arrangement as described above has the feature that when installing the door, the mutual positioning of the two striations or groove moldings takes place automatically as follows. This means that a groove or groove molding on the front side of the hinge hole of another hinge wing slides into a groove or groove molding on the upper surface of the axial zone of the hinge shaft, and if necessary, the hinge hole of the hinge half. The hinge shaft, which is supported by the hinge shaft, is rotated by a matching amount.

According to another embodiment of the invention, the upper surface of the axial zone of the hinge shaft is ball-shaped or spherical and the front surface of the hinge hole of the further hinge wing is designed like a hemispherical cap, the upper surface of the axial zone of the hinge shaft being shaped like a hemispherical cap. The striations or groove moldings of and the striations or groove moldings in front of the hinge hole of the other hinge wing are formed according to the spatial shape of both parts. Furthermore, according to the invention, the diameter of the hinge shaft, in its long portion projecting upwardly beyond its shaft zone, is greater than the diameter of the hinge hole in the other half of the hinge by an amount that forms the necessary clearance for adjustment. The axis of the hinge hole of the other half of the hinge is also formed narrowly so that the axis of the hinge hole of the other half of the hinge is at an angle to the axis of the hinge shaft, and on the shank band resting on the upper front of the hinge hole of the hinge half. It is possible to be supported by Thereby, slight alignment errors between the upper and lower door hinges of the motor vehicle door can be compensated for in this way even during the installation of the door on the crudely assembled vehicle body. In connection with the embodiment of the removable hinge according to the invention as described above, it is further provided that the upper extent of the hinge shaft passes through the hinge hole of the other half of the hinge and projects upwardly and that the hinge shaft has a Provision is made for a retaining element to be provided which rests on the upper front side of the hinge hole of the other half and is inserted or penetrated into the shaft.

In addition to the fact that the maintenance-free hinge shaft bearing allows the vehicle door to be easily removed and installed, it also prevents the door from being inadvertently installed on the hinge over the range of swivel angles in which the door is used. In order to make it impossible to be lifted out of position, a further embodiment is proposed, which is characterized in that it has a combination of the following features.

(a) The hinge shaft is continuously retained in the hinge hole of the hinge half and is secured against axial movement and is freely rotatable and provided with a cylinder made of bearing material. It is connected in such a way that there is no need for maintenance.

(b) The hinge axis is formed by an axially extending and radially projecting or recessed striation or groove molding, which forms the hinge hole in the other half of the hinge, which has a corresponding and oppositely oriented molding. It slides into engagement without being locked in its axial movement.

(c) both hinge halves are arranged alternately and circumferentially circumferentially and interdigitate over a predetermined range of operating angles of rotation; Movement in the axial direction is mutually prevented through the overhanging portion and the notch.

A device for blocking both hinge halves, which is effective over the entire range of swivel angles of use of the hinge, ensures that the hinge cannot be inadvertently removed or separated in any possible use position. do.

In order to facilitate the installation of an automobile door, the part of the hinge shaft that is fitted into the hinge hole in the half of the removable hinge has a region with a strip or groove molded part around the cylindrical tip region. and the hinge hole of the removable hinge half has a portion of the hole shaped to correspond to the component. In this case, the region of the cylindrical tip of the hinge shaft is formed at its upper end as a spherical head, and
It is expedient to have a smaller diameter than the perforation of the hinge hole in the half of the removable hinge. The area of the tip can thus fit into and guide the hinge hole of the removable hinge half even if the door is incorrectly inserted into the hinge axis. The overhangs and slit-like cutouts arranged alternately to block both hinge halves mean that the radially oriented overhangs are always located at the hinge holes of the hinge halves and are It is expedient that the slit-like recess is always arranged outside the area of the hinge hole in the hinge wing of the other half of the hinge. In this case, a radially oriented overhang located in the hinge hole of the removable half of the hinge, extending over a part of the height of the hinge, and intersecting the hinge wing at a certain angle, A slit-like notch is attached to the half of the hinged wing. An arrangement opposite to the above is also possible, in which case a slit-shaped cutout outside the range of the hinge hole in the half-wing of the removable hinge is used to ensure that it is not permanently fixed to the vehicle. A radial bulge is provided at the hinge hole on one half of the hinge.

In further individual developments of the invention, the following is taken into account. That is, the peripheral toothed portion running in the axial direction of the hinge shaft and projecting or recessed in the radial direction is provided at the tip of the long cylindrical portion of the hinge shaft, and the diameter of the long cylindrical portion of the hinge shaft is is larger than the diameter of the outer end tip circle of the part having the toothed part around it. In this case, the diameter of the long cylindrical part of the hinge shaft is only a fraction smaller than the diameter of the outer tip circle with the toothed part on the periphery.
In particular, it is only 1/10 the size. In this case, the hinge hole of the second half of the hinge is formed with a corresponding toothed section, so that the lower part of the hinge hole has a cylindrical smooth surface and the upper part of the hinge hole has an inner surface. It has a toothed surface around the periphery, and the diameter of the dedendum circle is made smaller corresponding to the step around the hinge shaft. The lower part of the second half of the hinge, which possesses a larger inner diameter, therefore becomes a guideway for the upper part, which is geared around the hinge axis, when installing the hinge, and its With this aid, the hinge shaft can be inserted into the gearing around the hinge hole in the shortest possible time.

The part of the hinge hole in the second half of the hinge attached to the long cylindrical part of the hinge shaft fits into the long cylindrical part of the hinge shaft without any play, so that the hinge shaft and the second half of the hinge No angular displacement between the halves occurs. In this case, it is expedient for the length of the long cylindrical part of the hinge shaft to be greater than the length of the circumferentially toothed part and several times the length of the toothed part.

In order to manufacture the door hinge as a mass-produced component as rationally and therefore economically as possible, a uniform hinge cross section is used for the production of both hinge halves for door hinges with different operating swivel angle ranges. In particular, the following features of the present invention are proposed. That is, a notch parallel to the hinge axis in the first half of the hinge is provided with an overhang pointing in the radial direction of the second half of the hinge, the overhang being curved in an arc with respect to the hinge axis. The length of the arc of this portion extends over the maximum allowable hinge opening angle for a door hinge of this construction. In this case, it is expedient for the radial bulge of the second half of the hinge to be formed by machining the arrangement of the bulge, which is formed integrally with the corresponding cross-section of the hinge half. .

In this case, the radially oriented bulge of the second half of the hinge extends over the entire height of its hinge hole and the front face of its upper part is beveled obliquely, the chamfer being The purpose is to facilitate the entry of this overhang into the cutout in the first half of the hinge.

When manufacturing and installing removable door hinges with different operating pivot angles from a uniform hinge cross-section, the arc length of the radially directed overhang of the second half of the hinge have different permissible use opening angles, the special feature of being attached to a common removal opening angle is obtained.
