Definitions

  • the invention relates to a temporary holding device according to the preamble of claim 1, in particular for use in a vehicle door hinge, in order to temporarily hold a vehicle door in an open position.
  • the invention also relates to a vehicle hinge according to the preamble of claim 9 and a holding system according to the preamble of claim 12.
  • the vehicle body and vehicle doors are typically painted together in a single process step after the vehicle doors have been assembled to the body. It is desirable to lock vehicle doors temporarily held in an open position so that certain painting operations, e.g. B. a top coat finish can be performed.
  • CN 204 492 417 U describes a temporary retaining device for a vehicle hinge, which fixes first and second hinge parts.
  • the holding device comprises a removable flat section for a stop part designed as a pin, which is arranged on the first hinge part and is used during the painting of the vehicle body, including the vehicle doors that have already been installed, in order to lock the vehicle doors in a defined open position.
  • the flat section is mounted on the second hinge part for this purpose, with a fold extending from the flat section being inserted into a recess in the second hinge part so that it can be coupled.
  • the flat section comprises a total of two openings, one of which is penetrated by a provisional hinge pin, which also penetrates the two hinge parts and connects them to one another in an articulated manner.
  • the second opening of the flat section is provided for the pin to snap into place.
  • the flat section has a bent upwards, tongue-like ramp section, which is arranged asymmetrically with respect to the fold. In order to lock the vehicle door, it is pivoted so that the ramp section contacts the pin and at the same time is guided up on the pin. Finally, the flat section is displaced partially vertically upwards until the second opening snaps into place with the pin. From then on, the vehicle door is locked in an open position.
  • the hinge pin can also be displaced upwards in its longitudinal direction by the displacement or by a substantially vertical movement of the flat section.
  • the hinge bolt can come loose from a lower hinge eye of a hinge part, so that the two hinge parts of the vehicle door hinge are no longer fully coupled.
  • an additional safety ring is mounted in a radial groove at the lower end of the hinge pin to prevent the hinge pin from shifting in its longitudinal direction.
  • the pin, the openings of the flat section and the position of the flat section specified by the hinge pin or by the second hinge part make the holding system, consisting of a holding device and a vehicle hinge, susceptible to problems due to tolerance deviations, so that the functionality of the holding device is unreliable is.
  • this object is achieved by a temporary holding device having the features of claim 1 or by a vehicle hinge having the features of claim 9 or by a holding system having the features of claim 12 solved.
  • a temporary retention device for use in a vehicle hinge to temporarily lock a vehicle door in an open position relative to a door frame, comprising a planar portion having an opening therein, extending from an edge of the planar portion a fold protrudes.
  • the holding device is characterized in that a load arm extends from the flat section, and in that the load arm has an embossing designed as a holding lug at an end remote from the flat section.
  • the holding device can be coupled in a simple manner to a hinge part of a vehicle hinge in order to specify a preferred opening angle of a door coupled to the vehicle via the hinge.
  • the holding device is easy to manufacture and in particular enables the hinge parts to be reliably fixed relative to one another without complicated threading in or out being necessary for this purpose.
  • the functions of securing the hinge parts against pivoting in one direction and in the other direction are advantageously decoupled, so that the holding device can also be disengaged again without being destroyed.
  • the retaining lug expediently comprises a flat mating surface on the one hand and a guide bevel on the other.
  • the mating surface is intended to come into clamping or gripping engagement with an end face of a stop part arranged on a hinge part and accordingly to provide a fixation that defines the preferred opening angle with a minimum moment to be overcome.
  • the retaining lug is expediently provided outside the plane of the load arm and is supported by a guide bevel, which can be designed as a bulbous expression of the load arm. As a result, the moments can be transmitted in a particularly favorable manner.
  • the load arm is expediently elastically bendable in the radial direction, so that cushioning of an impact occurs when torque is applied toward the outer surface of the load arm.
  • a free end of the load arm has an arcuate section, which thus advantageously defines a guide bevel that promotes pivoting past the stop part arranged on the hinge side.
  • the fold is expediently designed as a surface of the flat section that is folded over by approximately 90°. However, it is possible to form the fold in a step-like manner or, preferably, in a wavy manner.
  • the fold is used in particular to come into planar contact with the complementarily shaped end face of a hinge part.
  • the flat section preferably has a bead which is provided for stiffening and stabilizing the flat section and which also ensures elastic deformability so that the flat section can be adapted to tolerances of the hinge part to which it is to be connected.
  • the bead also makes it easier to remove the temporary holding device after use.
  • the load arm is preferably designed in such a way that when the load arm is elastically displaced in the radial direction, relatively low stresses occur inside the load arm, with the load arm having a high degree of rigidity, particularly in the tangential direction, which makes it possible to apply a torque in a range of 2 Nm to 20 Nm without the load arm buckling or bending.
  • the holding device is formed in one piece from a single piece of material.
  • a steel sheet that is shaped by stamping and is thin-walled and elastic at the same time is particularly suitable for this purpose.
  • the load arm has a contact surface which is provided adjacent to the retaining lug for interaction with a stop part which is arranged on one of the hinge parts.
  • the contact surface limits the pivoting in one direction, while the retaining lug limits the pivoting in the other direction by clamping.
  • the retaining lug is connected to the stop in a frictionally or force-fitting manner, while the contact surface prevents further opening in a form-fitting manner. The contact surface thus limits the pivoting movement in the opening direction, while the retaining lug prevents the pivoting movement in the closing direction.
  • a vehicle hinge comprising a first hinge part with a fastening surface for connection to a door or to a door frame, and at least one bracket in which a hinge eye is arranged, with a stop part being arranged on a surface of the bracket, a second hinge part, and a hinge pin passing through the first and second hinge parts and pivotally connecting the first and second hinge parts together about a pivot axis.
  • the vehicle hinge is preferably characterized in that the stop part is designed as a U-shaped bracket with two legs and a base connecting the legs, each of which protrudes from the extension arm.
  • the vehicle hinge thus advantageously provides a stop part that can be connected to the extension arm in a simple manner and provides a number of surfaces to which different functions can be assigned.
  • the U-bend shackle provides a large surface area without increasing the mass of the striker.
  • the bracket bent in a U-shape makes it possible for different outward-facing surfaces of the legs or the base to have different parts cooperate and each provide a defined opening angle of the door to be attached via the vehicle hinge.
  • the stop part expediently limits the pivoting movement of the hinge parts and defines a maximum opening angle of the hinge.
  • a cantilever of the second hinge part strikes the stop part, preferably at its base, which ensures that the vehicle door does not roll over.
  • legs of a preferably U-shaped stop part run approximately parallel to the fastening surface of the first hinge part, so that the load arm can be guided past the U-shaped bracket without tilting.
  • One of the legs of the U-shaped bracket expediently has an end face remote from the base, which is designed to interact with the holding lug of a temporary holding device, as described above.
  • the end face is designed to be smooth, so that the retaining lug comes into contact with the end face under the prestressing of the load arm.
  • the end face can be formed by flat embossings on the stop part or on the U-shaped bracket. These can in the structural design of the stop part or the U-shaped bracket z. B. by a choice of flat or angled sheets or profiles, z. B. square profiles can be realized.
  • the retaining lug also engages in the intermediate space between the two legs through the opening of the U facing away from the base and thus also provides a form fit instead of or in addition to the frictional fixing. If the door is moved in the closing direction with a moment that exceeds 20 Nm, for example, the retaining lug is decoupled without the need for manual processing of the retaining device.
  • the U-shaped bracket is arranged with its base on the boom and between the A passage is arranged on the legs of the U-shaped bracket, which runs transversely, preferably at an angle of up to 45°, to a plane to the fastening surface.
  • the passage of the U-shaped bracket offers a possibility to use a defined adapter piece in this passage.
  • the angle is in a range between 5° and 25°, preferably between 7° and 15° and particularly preferably the angle is approximately 10° in order to advantageously lock a vehicle door at a defined opening angle.
  • a holding system for an automobile body shell to be painted comprising a hinge as described above, and a holding device as described above, wherein instead of the hinge pin of the hinge, a provisional hinge bolt couples the hinge parts in a pivotable manner and, moreover, the holding device connects to the second hinge part, wherein the holding lug of the arm of the holding device can be braced on the leg of the bracket, in particular on its front side, or on an adapter piece connected to the bracket, in order to lock the two hinge parts in a predetermined opening angle.
  • a provisional hinge bolt couples the hinge parts in a pivotable manner and, moreover, the holding device connects to the second hinge part, wherein the holding lug of the arm of the holding device can be braced on the leg of the bracket, in particular on its front side, or on an adapter piece connected to the bracket, in order to lock the two hinge parts in a predetermined opening angle.
  • the temporary hinge pin and bracket are discarded or recycled, and when the doors are reconnected to the body, the actual hinge pin is used to pivot the connection.
  • the fold of the holding device can be coupled to the second hinge part, and is preferably in a corresponding Recess definable. Due to the angle that the fold and the flat section have in relation to one another, favorable bracing occurs on the second hinge part.
  • the holding device and the second hinge part preferably have the same axis of rotation.
  • the holding force generated by the holding device in order to temporarily lock a vehicle door in the open position preferably has a torque of 2 Nm to 20 Nm, preferably 10 Nm to 18 Nm, particularly preferably 15 Nm to 17 Nm. This ensures that vibrations, which are not sufficient during transport of the body shell to be painted, to close the vehicle door locked in the open position by the holding device, so that a high level of reproducibility during painting work is ensured.
  • an adapter piece designed as a double-bent sheet metal part is inserted with its central region between the legs of the U-shaped bracket and that the retaining lug can be connected to an outer part of the double-bent sheet metal part.
  • different adapter pieces with, for example, differently defined stop surfaces and geometries or different materials can be used in the U-shaped bracket in order to ensure, for example, much higher torques for locking a vehicle door. This aspect increases the flexibility and range of use of the holding system.
