Definitions
- the invention relates to a hinge arrangement with a first hinge part and with a second hinge part which is pivotally connected to the first hinge part, a first hinge pin being formed on the first hinge part, which extends along a hinge axis and a first hinge sleeve being pivotally mounted on the first hinge pin is, which forms a first plain bearing with the first hinge pin, with a solid support part being connected to the first hinge sleeve.
- a hinge arrangement can be used, for example, to pivotably mount a container lid on a container, the container being, for example, a waste container.
- a hinge with two hinge leaves and an axis common to these and with a device that dampens the hinge movement is known, the hinge axis being at least partially a hollow axis and being firmly connected to the first hinge leaf and a torsion spiral spring or torsion bar spring in the hollow axis is arranged in such a way that its spring torsional force acts in the hinge opening direction and that the hinge axis is connected to a damping arrangement for damping the hinge movement.
- the EP 2 574 714 A2 describes a pivot hinge assembly comprising a hinge housing having at least one interior chamber, a spring disposed within the hinge housing providing torque to an attached door while in an open or closed position, and a rotor rotatable in the at least one Inner chamber is arranged, comprises at least one rotor blade which moves with respect to a stationary mounted stator with at least one stator blade and a fill plug comprises a plurality of input and output holes which are arranged with respect to the stator and rotor blades to provide a fluidic Define damper assembly and wherein a valve disposed within the fill plug allows selective adjustment of the fluidic damper by restricting or opening the input and output holes of the fill plug.
- a damper which comprises a housing with a cylindrical chamber into which viscous fluids can be filled, and a rotating element connected to the housing so as to be rotatable relative thereto, the rotating element comprising a shaft element in the center which is rotatable in the chamber and wherein a movable valve is provided which can be anchored with play in the direction of rotation on an axial projection provided on the shaft element of the rotating element or on a wall surface in the chamber, and its another surface on a wall surface of the chamber or an outer surface of the shaft member can be displaced and at the same time rotatable, and with a plurality of viscous fluid channels each having different cross-sectional areas formed on a contact portion between the projection and the movable valve, so on that the resistance can be changed depending on a direction of relative rotation.
- the US 2009/0255767 A1 discloses an apparatus for braking movement of a movable member with respect to a support structure, comprising a housing attachable to the movable member or structure and defining a chamber containing a viscous braking fluid, and a rotor operative can be connected to the movable element or to the structure and which is rotatably connected to the housing and is attached thereto so as to close the chamber.
- the rotor includes a piston-like member mounted to slide within the chamber so as to divide the chamber into separate regions in fluid communication with one another.
- the piston-like member is movable integrally with the rotor so that the rotation of the rotor results in a rotational displacement of the piston-like member, which is braked by the resistance to the passage of fluid from one region to another of the chamber, which is caused by the displacement of the piston-like element or section is caused.
- the object of the invention is to provide a hinge arrangement of the type mentioned at the outset, which enables damping of the relative movement between the first hinge part and the second hinge part.
- a first axial projection is formed on a first axial end face of the first hinge pin, which engages in an arcuate first groove which is formed in the first hinge sleeve, with a circumferential first side wall of the first groove together with the first axial end face and an inside of an end cover fixed at the end of the first hinge sleeve delimits a working space in which a damping fluid is accommodated, which is designed to dampen a relative movement of the first hinge pin provided with the first axial projection relative to the first hinge sleeve.
- the arcuate first groove has a profiling designed as a circular ring section in a cross-sectional plane aligned transversely to the hinge axis.
- the first axial projection in this cross-sectional plane also has, purely as an example, a profiling designed as a circular ring section, the first groove and the first axial projection being coordinated with one another in such a way that a pivoting movement of the first hinge part relative to the second hinge part can be carried out with a pivot angle of, for example, 90 degrees .
- a damping fluid which can be, for example, a silicone oil
- the first axial projection which is located in the arcuate first Groove moves on an arcuate path around the hinge axis.
- the first axial projection and the first groove are adapted to one another in such a way that at least one movement gap is formed between the first axial projection and a circumferential first side wall of the first groove, through which the damping fluid must flow in order to prevent the relative movement between the first axial projection and the first groove to enable.
- a dimensioning of the at least one movement gap is based on the properties, in particular the viscosity of the preferably at least almost completely incompressible damping fluid in order to achieve the desired limitation of a movement speed for the second hinge part compared to the first hinge part.
- the first axial end face of the first hinge pin and the inside of the end cover fixed to the end of the first hinge sleeve are arranged adjacent to the circumferential first side wall of the first groove. This limits a working space in which the damping fluid is enclosed. This ensures that the desired displacement effect for the damping fluid is guaranteed by the axial projection during the relative movement between the first hinge part and the second hinge part.
- the arcuate first groove is formed in the first axial end face of the first hinge pin and that the first axial projection is assigned to the first hinge sleeve and engages in this groove.
- annular seal is arranged on the first end face of the first hinge sleeve and is designed to seal the working space.
- the annular seal is preferably made of a rubber-elastic material and can therefore be elastically deformed in order to ensure the desired sealing effect between the inside of the end cover and the first end face of the first hinge sleeve.
- a cross section of the annular seal in particular a round one, is selected such that a sealing effect between the end cover and the first hinge sleeve can be achieved within a certain deformation interval for the seal. This ensures a fault-tolerant assembly of the end cover on the first hinge sleeve.
- the end cover and the first hinge sleeve are each assigned corresponding thread sections, which form a screw connection which is designed to fix the end cover to the first hinge sleeve and to adjust the distance between the end cover and the first hinge sleeve. It is preferably provided that thread axes of the mutually corresponding threaded sections of the end cover and the first hinge sleeve are each aligned along the hinge axis and a screwing movement for this screw connection takes place coaxially to the hinge axis.
- the screw connection enables the end cover to be fixed to the first hinge sleeve, whereby a distance adjustment can be made by a screwing movement between the end cover and the first hinge sleeve.
- This distance setting influences the elastic deformation of the annular seal arranged between the first end face of the first hinge sleeve and the inside of the end cover and equally influenced the distance between the inside of the end cover and the first end face of the first hinge sleeve.
- a cross section of a movement gap available for the damping fluid changes. Accordingly, the damping behavior of the hinge arrangement can be adjusted by this distance adjustment.
- the threaded section of the end cover is integrally formed on the end cover. This makes it possible to produce the end cover cost-effectively, since additional sealing measures that would be required if a separate screw was used to fix the end cover can be dispensed with.
- a first, radially inner movement gap with a first cross-sectional area is formed between the first axial projection and a first, outward-facing wall section of the circumferential side wall of the first groove, that between the first axial projection and a second, inward-facing wall section of the A second, radially outer movement gap with a second cross-sectional area is formed in the circumferential side wall of the first groove, that a third axially aligned movement gap with a third cross-sectional area is formed between the first axial end face of the first hinge pin and an opposite end face of the first hinge sleeve, and that between an axial end face of the first axial projection and the inside of the end cover, a fourth, axially aligned movement gap is formed with a fourth cross-sectional area which is dependent on an axial positioning of the end cover relative to the first end face of the first hinge sleeve.
- the geometry of the first groove and the geometry of the first axial projection are selected such that the first, second and third cross-sectional areas do not change during a relative movement of the first hinge part with respect to the second hinge part.
- the geometry of the first groove is selected such that during the relative movement of the first hinge part with respect to the second hinge part, a change in a distance between a first side surface of the first axial projection and the oppositely arranged first wall section and / or a change in one Distance between a second side surface of the first axial projection and the oppositely arranged second wall section takes place.
- the change in the first cross-sectional area and/or the second cross-sectional area that also takes place here also leads to a damping effect that is dependent on the pivot angle between the first hinge part and the second hinge part, whereby an angle-dependent movement behavior of the second hinge part relative to the first hinge part can be specified.
- the fourth cross-sectional area can be adjusted between 0.1 times and 1.2 times a sum of the first cross-sectional area, the second cross-sectional area and the third cross-sectional area. This variation of the fourth cross-sectional area allows the desired setting of the damping behavior of the hinge arrangement to be achieved.
- a second axial projection is formed on the first axial end face of the first hinge pin, which is arranged offset by 180 degrees from the first axial projection in relation to the hinge axis and which is in an arcuate shape trained second groove engages, which is formed in the first hinge sleeve and which is arranged offset by 180 degrees to the first groove in relation to the hinge axis.

- the sliding sleeve is made from a plastic material such as polyoxymethylene (POM), which is also sold under the trade name Delrin, among others is, with which bearing friction between the first hinge pin and the first hinge sleeve can be specified in a narrow interval.
- a sealing ring is arranged between the first hinge pin and the first hinge sleeve, which seals the working space in an axial direction facing away from the end cover, so that no escape of damping fluid from the working space is possible in this area.
- the sealing ring which can in particular be designed as an O-ring, is received in a circumferential groove of a first carrier ring fixed in the first hinge sleeve.
- the carrier ring is, for example, pressed sealingly into the hinge sleeve and has the circumferential groove on its inner surface.

- the second hinge sleeve 27 is associated with the second hinge part 5, when the second hinge part 5 pivots relative to the first hinge part 4, a torsional movement is initiated in the coil spring 19, whereby either, depending on the direction of the pivoting movement a release of stored spring energy from the coil spring 19 or a storage of spring energy in the coil spring 19 takes place.
- the second hinge sleeve 27 is rotatably received on the second hinge pin 16, with a second sliding sleeve 32 being provided to ensure an advantageous sliding bearing between the second hinge sleeve 27 and the second hinge pin 16, which is slidably movable on the circular cylindrical outer surface 34 of the second Hinge pin 16 and on the circular cylindrical inner surface of the second hinge sleeve 27 (not shown).

- first axial projection 55 and a second axial projection 56 are arranged, each of which extends along the hinge axis 6 in a spatial direction facing away from the second hinge pin 16.
- first axial projection 55 and the second axial projection 56 are designed point-symmetrically to a point of symmetry, which results as an intersection between the hinge axis 6 and the first axial end face 54.
- the first axial projection 55 and the second axial projection 56 each have a profile designed as a circular ring section in a transverse to the hinge axis 6 aligned and the representation plane of the Figure 4 corresponding cross-sectional plane.
- the profiling of the first axial projection 55 and the second axial projection 56 which is designed as a circular ring section, each extends over an angular range of approximately 40 degrees.
- the through hole 52 has a first bore section 57, the first diameter 59 of which is larger than a second diameter 60 of a second bore section 58. Furthermore, it is provided that in the second bore section 58 there is also one in the Figure 4 recognizable web 61 is formed, which extends along the second diameter 60.

- the geometric configuration described above of the first axial projection 55, which engages in the first groove 62, and of the second axial projection 56, which engages the second groove 63, enables a pivoting movement of the first hinge part 4 relative to the second hinge part 5 about the hinge axis 6 in an angular range of approximately 95 degrees.
- the mode of operation of the damping device 12 is described below based on the interaction between the first axial projection 55, the first groove 62 and a damping fluid, not shown in detail, this mode of operation also being applicable in the same way to the interaction between the second axial projection 56, the second groove 63 and the Damping fluid not shown in detail applies.
- the first groove 62 has a circumferential first side wall 65, which comprises a first, outward-facing wall section 66 and a second, inwardly projecting wall section 67, both wall sections 66, 67 each having a circular arc section-shaped profile in a direction transverse to the hinge axis 6 and have a cross-sectional plane corresponding to the representation plane of Figure 4.

- first movement gap 74 is formed between an outer surface 71 of the first axial projection 55 which is profiled in the shape of a circular arc section and the second wall section 67. It also forms an end face 64 of the web 61 and the first axial end face 54 have a third movement gap 76.
- a fourth movement gap 77 is formed between a first axial end face 72 of the first axial projection 55 and an inside 83 of an end cover 82.
- the end cover 82 is designed to be rotationally symmetrical to the hinge axis 6 and includes a threaded pin 84 which extends along the hinge axis 6 from the inner side 83, which is, for example, flat and aligned transversely to the hinge axis 6 and which is provided with an unidentified external thread.
- the external thread of the threaded pin 84 is intended to engage in a threaded hole 85, which is introduced into the web 61 coaxially with the hinge axis 6 and which, together with the threaded pin 84, forms a screw connection 86. With this screw connection 86, on the one hand, the end cover 82 can be secured to the first hinge sleeve 26.
- this screw connection 86 enables an adjustment of a distance 90 between the inside 83 of the end cover 82 and a first end face 37 of the first hinge sleeve 26. This distance adjustment also results in an adjustment of a cross section of the fourth movement gap 77, with which the properties of the damping device 12 can be influenced .
- the mode of operation of the damping device 12 is based on the fact that in the Figure 4 shown first side wall 65 of the first groove 62, the first axial end face 54 of the first hinge pin 15 and the inside 83 of the end cover 82 delimit a working space 91.
- a Sealing ring 87 is provided, which is arranged between the first end face 37 and the inside 83.
- the sealing ring 87 is made of a rubber-elastic material and, purely as an example, is accommodated in a circumferential groove 38 of the first end face 37 and, due to its elasticity, can ensure a sealing effect between the end cover 82 and the first hinge sleeve 26 over a certain distance interval.
- the first axial projection 55 engages in the working space 91, and on the other hand, this working space 91 is preferably completely filled with a damping fluid (not shown), for example a mineral or synthetic oil, in particular a silicone oil. Accordingly, during a relative movement between the first hinge part 4 and the second hinge part 5, a relative movement of the first axial projection 55 relative to the first groove 62 also takes place. Since the working space 91 is preferably completely filled with the damping fluid, it is necessary to carry out this relative movement between the first axial projection 55 and the first groove 62 require that the damping fluid is displaced by the first axial projection 55 from a first variable-size working space section 92 and can flow into a second variable-size working space section 93. Since the damping fluid can only flow through the movement gaps 74 to 77, which provide a significant flow resistance for the damping fluid, the desired damping of the relative movement between the first hinge part 4 and the second hinge part 5 is ensured.

Die Aufgabe der Erfindung besteht darin, eine Scharnieranordnung der eingangs genannten Art bereitzustellen, die eine Dämpfung der Relativbewegung zwischen dem ersten Scharnierteil und dem zweiten Scharnierteil ermöglicht.The object of the invention is to provide a hinge arrangement of the type mentioned at the outset, which enables damping of the relative movement between the first hinge part and the second hinge part.
Diese Aufgabe wird für eine Scharnieranordnung der eingangs genannten Art mit den Merkmalen des Anspruchs 1 gelöst. Hierbei ist vorgesehen, dass an einer ersten Axialstirnfläche des ersten Scharnierzapfens ein erster Axialvorsprung ausgebildet ist, der in eine bogenförmig ausgebildete erste Nut eingreift, die in der ersten Scharnierhülse ausgebildet ist, wobei eine umlaufende erste Seitenwand der ersten Nut zusammen mit der ersten Axialstirnfläche und einer Innenseite eines endseitig an der ersten Scharnierhülse festgelegten Abschlussdeckels einen Arbeitsraum begrenzt, in dem eine Dämpfungsflüssigkeit aufgenommen ist, die für eine Bedämpfung einer Relativbewegung des mit dem ersten Axialvorsprung versehenen ersten Scharnierzapfens gegenüber der ersten Scharnierhülse ausgebildet ist.This task is achieved for a hinge arrangement of the type mentioned with the features of
Beispielhaft weist die bogenförmige erste Nut in einer quer zur Scharnierachse ausgerichteten Querschnittsebene eine als Kreisringabschnitt ausgebildete Profilierung auf. Der erste Axialvorsprung weist in dieser Querschnittsebene ebenfalls rein exemplarisch eine als Kreisringabschnitt ausgebildete Profilierung auf, wobei die erste Nut und der erste Axialvorsprung derart aufeinander abgestimmt sind, dass eine Schwenkbewegung des ersten Scharnierteils gegenüber dem zweiten Scharnierteil mit einem Schwenkwinkel von beispielsweise 90 Grad durchgeführt werden kann.By way of example, the arcuate first groove has a profiling designed as a circular ring section in a cross-sectional plane aligned transversely to the hinge axis. The first axial projection in this cross-sectional plane also has, purely as an example, a profiling designed as a circular ring section, the first groove and the first axial projection being coordinated with one another in such a way that a pivoting movement of the first hinge part relative to the second hinge part can be carried out with a pivot angle of, for example, 90 degrees .
Um eine Bedämpfung einer Relativbewegung zwischen dem ersten Scharnierteil und dem zweiten Scharnierteil zu ermöglichen, erfolgt bei der erfindungsgemäßen Scharnieranordnung eine Verdrängung einer Dämpfungsflüssigkeit, bei der es sich beispielsweise um ein Silikonöl handeln kann, mit Hilfe des ersten Axialvorsprungs, der sich in der bogenförmig ausgebildeten ersten Nut auf einer bogenförmigen Bahn um die Scharnierachse bewegt. Dabei sind der erste Axialvorsprung und die erste Nut derart aufeinander angepasst, dass zwischen dem ersten Axialvorsprung und einer umlaufenden ersten Seitenwand der ersten Nut wenigstens ein Bewegungsspalt ausgebildet ist, durch den die Dämpfungsflüssigkeit strömen muss, um die Relativbewegung zwischen dem ersten Axialvorsprung und der ersten Nut zu ermöglichen. Eine Dimensionierung des wenigstens einen Bewegungsspalts ist hierbei auf die Eigenschaften, insbesondere die Viskosität, der vorzugsweise zumindest nahezu vollständig inkompressiblen Dämpfungsflüssigkeit anzupassen, um die gewünschte Begrenzung einer Bewegungsgeschwindigkeit für das zweite Scharnierteil gegenüber dem ersten Scharnierteil zu erzielen.In order to enable damping of a relative movement between the first hinge part and the second hinge part, in the hinge arrangement according to the invention a damping fluid, which can be, for example, a silicone oil, is displaced with the aid of the first axial projection, which is located in the arcuate first Groove moves on an arcuate path around the hinge axis. The first axial projection and the first groove are adapted to one another in such a way that at least one movement gap is formed between the first axial projection and a circumferential first side wall of the first groove, through which the damping fluid must flow in order to prevent the relative movement between the first axial projection and the first groove to enable. A dimensioning of the at least one movement gap is based on the properties, in particular the viscosity of the preferably at least almost completely incompressible damping fluid in order to achieve the desired limitation of a movement speed for the second hinge part compared to the first hinge part.
Um ein Entweichen der Dämpfungsflüssigkeit aus der bogenförmig ausgebildeten ersten Nut zu verhindern, sind angrenzend an die umlaufende erste Seitenwand der ersten Nut zum einen die erste Axialstirnfläche des ersten Scharnierzapfens sowie die Innenseite des endseitig an der ersten Scharnierhülse festgelegten Abschlussdeckels angeordnet. Hierdurch wird ein Arbeitsraum begrenzt, in dem die Dämpfungsflüssigkeit eingeschlossen ist. Somit wird sichergestellt, dass bei der Relativbewegung zwischen dem ersten Scharnierteil und dem zweiten Scharnierteil die gewünschte Verdrängungswirkung für die Dämpfungsflüssigkeit durch den Axialvorsprung gewährleistet ist.In order to prevent the damping fluid from escaping from the arcuate first groove, the first axial end face of the first hinge pin and the inside of the end cover fixed to the end of the first hinge sleeve are arranged adjacent to the circumferential first side wall of the first groove. This limits a working space in which the damping fluid is enclosed. This ensures that the desired displacement effect for the damping fluid is guaranteed by the axial projection during the relative movement between the first hinge part and the second hinge part.
Alternativ zu der vorstehend beschriebenen Anordnung, jedoch nicht beansprucht, kann vorgesehen sein, dass die bogenförmig ausgebildete erste Nut in der ersten Axialstirnfläche des ersten Scharnierzapfens ausgebildet ist und dass der erste Axialvorsprung der ersten Scharnierhülse zugeordnet ist und in diese Nut eingreift. Diese kinematische Umkehr der vorstehend beschriebenen Anordnung von erstem Axialvorsprung und erster Nut verwirklicht die gleiche Funktionalität.As an alternative to the arrangement described above, but not claimed, it can be provided that the arcuate first groove is formed in the first axial end face of the first hinge pin and that the first axial projection is assigned to the first hinge sleeve and engages in this groove. This kinematic reversal of the arrangement of the first axial projection and first groove described above realizes the same functionality.
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous developments of the invention are the subject of the subclaims.
Zweckmäßig ist es, wenn zwischen dem Abschlussdeckel, insbesondere zwischen der Innenseite des Abschlussdeckels, und einer ersten Stirnfläche der ersten Scharnierhülse eine ringförmige Dichtung angeordnet ist, die zur Abdichtung des Arbeitsraums ausgebildet ist. Die ringförmige Dichtung ist vorzugsweise aus einem gummielastischen Material hergestellt und kann somit elastisch deformiert werden, um die gewünschte Dichtwirkung zwischen der Innenseite des Abschlussdeckels und der ersten Stirnfläche der ersten Scharnierhülse zu gewährleisten. Vorzugsweise ist ein, insbesondere runder, Querschnitt der ringförmigen Dichtung derart gewählt, dass eine Dichtwirkung zwischen Abschlussdeckel und erster Scharnierhülse innerhalb eines gewissen Deformationsintervalls für die Dichtung verwirklicht werden kann. Hierdurch wird eine fehlertolerante Montage des Abschlussdeckels an die erste Scharnierhülse sichergestellt.It is useful if between the end cover, in particular between the inside of the end cover, and one An annular seal is arranged on the first end face of the first hinge sleeve and is designed to seal the working space. The annular seal is preferably made of a rubber-elastic material and can therefore be elastically deformed in order to ensure the desired sealing effect between the inside of the end cover and the first end face of the first hinge sleeve. Preferably, a cross section of the annular seal, in particular a round one, is selected such that a sealing effect between the end cover and the first hinge sleeve can be achieved within a certain deformation interval for the seal. This ensures a fault-tolerant assembly of the end cover on the first hinge sleeve.
Bei einer Weiterbildung der Erfindung ist vorgesehen, dass dem Abschlussdeckel und der ersten Scharnierhülse jeweils zueinander korrespondierende Gewindeabschnitte zugeordnet sind, die eine Schraubverbindung bilden, die für eine Festlegung des Abschlussdeckels an der ersten Scharnierhülse und für eine Abstandseinstellung des Abschlussdeckels gegenüber der ersten Scharnierhülse ausgebildet ist. Bevorzugt ist vorgesehen, dass Gewindeachsen der zueinander korrespondierenden Gewindeabschnitte des Abschlussdeckels und der ersten Scharnierhülse jeweils längs der Scharnierachse ausgerichtet sind und eine Schraubbewegung für diese Schraubverbindung koaxial zur Scharnierachse stattfindet. Die Schraubverbindung ermöglicht die Festlegung des Abschlussdeckels an der ersten Scharnierhülse, wobei durch eine Schraubbewegung zwischen Abschlussdeckel und erster Scharnierhülse eine Abstandseinstellung vorgenommen werden kann. Mit dieser Abstandseinstellung wird Einfluss auf die elastische Deformation der zwischen der ersten Stirnfläche der ersten Scharnierhülse und der Innenseite des Abschlussdeckels angeordneten ringförmigen Dichtung und gleichermaßen Einfluss auf den Abstand zwischen der Innenseite des Abschlussdeckels und der ersten Stirnfläche der ersten Scharnierhülse genommen. Mit dieser Abstandseinstellung ändert sich ein Querschnitt eines für die Dämpfungsflüssigkeit zur Verfügung stehenden Bewegungsspalts. Dementsprechend kann durch diese Abstandseinstellung das Dämpfungsverhalten der Scharnieranordnung eingestellt werden.In a further development of the invention it is provided that the end cover and the first hinge sleeve are each assigned corresponding thread sections, which form a screw connection which is designed to fix the end cover to the first hinge sleeve and to adjust the distance between the end cover and the first hinge sleeve. It is preferably provided that thread axes of the mutually corresponding threaded sections of the end cover and the first hinge sleeve are each aligned along the hinge axis and a screwing movement for this screw connection takes place coaxially to the hinge axis. The screw connection enables the end cover to be fixed to the first hinge sleeve, whereby a distance adjustment can be made by a screwing movement between the end cover and the first hinge sleeve. This distance setting influences the elastic deformation of the annular seal arranged between the first end face of the first hinge sleeve and the inside of the end cover and equally influenced the distance between the inside of the end cover and the first end face of the first hinge sleeve. With this distance setting, a cross section of a movement gap available for the damping fluid changes. Accordingly, the damping behavior of the hinge arrangement can be adjusted by this distance adjustment.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass der Gewindeabschnitt des Abschlussdeckels einstückig am Abschlussdeckel angeformt ist. Hierdurch ist eine kostengünstige Herstellung des Abschlussdeckels möglich, da auf zusätzliche Dichtmaßnahmen verzichtet werden kann, die bei Nutzung einer separaten Schraube zur Festlegung des Abschlussdeckels erforderlich wären.In a further embodiment of the invention it is provided that the threaded section of the end cover is integrally formed on the end cover. This makes it possible to produce the end cover cost-effectively, since additional sealing measures that would be required if a separate screw was used to fix the end cover can be dispensed with.
Bevorzugt ist vorgesehen, dass zwischen dem ersten Axialvorsprung und einem ersten, nach außen weisenden Wandabschnitt der umlaufenden Seitenwand der ersten Nut ein erster, radial innenliegender Bewegungsspalt mit einer ersten Querschnittsfläche ausgebildet ist, dass zwischen dem ersten Axialvorsprung und einem zweiten, nach innen weisenden Wandabschnitt der umlaufenden Seitenwand der ersten Nut ein zweiter, radial außenliegender Bewegungsspalt mit einer zweiten Querschnittsfläche ausgebildet ist, dass zwischen der ersten Axialstirnfläche des ersten Scharnierzapfens und einer gegenüberliegenden Stirnfläche der ersten Scharnierhülse ein dritter axial ausgerichteter Bewegungsspalt mit einer dritten Querschnittsfläche ausgebildet ist und dass zwischen einer axialen Stirnfläche des ersten Axialvorsprungs und der Innenseite des Abschlussdeckels ein vierter, axial ausgerichteter Bewegungsspalt mit einer vierten, von einer axialen Positionierung des Abschlussdeckels gegenüber der ersten Stirnfläche der ersten Scharnierhülse abhängigen Querschnittsfläche ausgebildet ist.It is preferably provided that a first, radially inner movement gap with a first cross-sectional area is formed between the first axial projection and a first, outward-facing wall section of the circumferential side wall of the first groove, that between the first axial projection and a second, inward-facing wall section of the A second, radially outer movement gap with a second cross-sectional area is formed in the circumferential side wall of the first groove, that a third axially aligned movement gap with a third cross-sectional area is formed between the first axial end face of the first hinge pin and an opposite end face of the first hinge sleeve, and that between an axial end face of the first axial projection and the inside of the end cover, a fourth, axially aligned movement gap is formed with a fourth cross-sectional area which is dependent on an axial positioning of the end cover relative to the first end face of the first hinge sleeve.
Beispielhaft ist vorgesehen, dass die Geometrie der ersten Nut sowie die Geometrie des ersten Axialvorsprungs derart gewählt sind, dass sich die erste, zweite und dritte Querschnittsfläche während einer Relativbewegung des ersten Scharnierteils gegenüber dem zweiten Scharnierteil nicht verändern. Alternativ kann auch vorgesehen sein, dass die Geometrie der ersten Nut derart gewählt ist, dass während der Relativbewegung des ersten Scharnierteils gegenüber dem zweiten Scharnierteil eine Veränderung eines Abstands zwischen einer ersten Seitenfläche des ersten Axialvorsprungs und dem gegenüberliegend angeordneten ersten Wandabschnitt und/oder eine Veränderung eines Abstands zwischen einer zweiten Seitenfläche des ersten Axialvorsprungs und dem gegenüberliegend angeordneten zweiten Wandabschnitt stattfindet. Die hierbei ebenfalls stattfindende Veränderung der ersten Querschnittsfläche und/oder der zweiten Querschnittsfläche führt damit auch zu einer vom Schwenkwinkel zwischen dem ersten Scharnierteil und dem zweiten Scharnierteil abhängigen Dämpfungswirkung, wodurch ein winkelabhängiges Bewegungsverhalten des zweiten Scharnierteils gegenüber dem ersten Scharnierteil vorgegeben werden kann.By way of example, it is provided that the geometry of the first groove and the geometry of the first axial projection are selected such that the first, second and third cross-sectional areas do not change during a relative movement of the first hinge part with respect to the second hinge part. Alternatively, it can also be provided that the geometry of the first groove is selected such that during the relative movement of the first hinge part with respect to the second hinge part, a change in a distance between a first side surface of the first axial projection and the oppositely arranged first wall section and / or a change in one Distance between a second side surface of the first axial projection and the oppositely arranged second wall section takes place. The change in the first cross-sectional area and/or the second cross-sectional area that also takes place here also leads to a damping effect that is dependent on the pivot angle between the first hinge part and the second hinge part, whereby an angle-dependent movement behavior of the second hinge part relative to the first hinge part can be specified.
Vorteilhaft ist es, wenn die vierte Querschnittsfläche zwischen einem 0,1-fachen und einem 1,2-fachen einer Summe der ersten Querschnittsfläche, der zweiten Querschnittsfläche und der dritten Querschnittsfläche einstellbar ist. Durch diese Variation der vierten Querschnittsfläche kann die gewünschte Einstellung des Dämpfungsverhaltens der Scharnieranordnung erzielt werden.It is advantageous if the fourth cross-sectional area can be adjusted between 0.1 times and 1.2 times a sum of the first cross-sectional area, the second cross-sectional area and the third cross-sectional area. This variation of the fourth cross-sectional area allows the desired setting of the damping behavior of the hinge arrangement to be achieved.
Zweckmäßig ist es, wenn an der ersten Axialstirnfläche des ersten Scharnierzapfens ein zweiter Axialvorsprung ausgebildet ist, der bezogen zur Scharnierachse um 180 Grad versetzt zum ersten Axialvorsprung angeordnet ist und der in eine bogenförmig ausgebildete zweite Nut eingreift, die in der ersten Scharnierhülse ausgebildet ist und die bezogen zur Scharnierachse um 180 Grad versetzt zur ersten Nut angeordnet ist. Hierdurch wird in einem kompakten Bauraum eine deutliche Vergrößerung der Dämpfungswirkung zwischen dem ersten Scharnierteil und dem zweiten Scharnierteil verwirklicht. Beispielhaft ist vorgesehen, dass die zweite Nut und der zweite Axialvorsprung hinsichtlich ihrer jeweiligen Geometrien identisch zur ersten Nut und zum ersten Axialvorsprung ausgebildet sind. Alternativ kann auch vorgesehen sein, dass Abweichungen zwischen den Geometrien der ersten Nut und der zweiten Nut und/oder des ersten Axialvorsprungs und des zweiten Axialvorsprungs vorliegen, um spezifische Dämpfungseigenschaften hervorrufen zu können.It is expedient if a second axial projection is formed on the first axial end face of the first hinge pin, which is arranged offset by 180 degrees from the first axial projection in relation to the hinge axis and which is in an arcuate shape trained second groove engages, which is formed in the first hinge sleeve and which is arranged offset by 180 degrees to the first groove in relation to the hinge axis. This results in a significant increase in the damping effect between the first hinge part and the second hinge part in a compact installation space. By way of example, it is provided that the second groove and the second axial projection are designed identically to the first groove and the first axial projection with regard to their respective geometries. Alternatively, it can also be provided that there are deviations between the geometries of the first groove and the second groove and/or the first axial projection and the second axial projection in order to be able to produce specific damping properties.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass am ersten Scharnierteil ein zweiter Scharnierzapfen ausgebildet ist, der in einer dem ersten Scharnierzapfen entgegengesetzten Richtung längs der Scharnierachse erstreckt ist, wobei am zweiten Scharnierzapfen eine zweite Scharnierhülse schwenkbeweglich gelagert ist, die mit dem zweiten Scharnierzapfen ein zweites Gleitlager bildet, wobei das gestaltfeste Trägerteil für eine Verbindung der ersten Scharnierhülse mit der zweiten Scharnierhülse ausgebildet ist. Hiermit wird eine vorteilhafte, insbesondere symmetrische, Kraftübertragung zwischen dem ersten Scharnierteil und dem zweiten Scharnierteil gewährleistet, so dass die Scharnieranordnung auch für hohe Belastungen eingesetzt werden kann, wie sie beispielsweise bei Möbelbeschlägen oder Abfalleimern auftreten.In a further embodiment of the invention it is provided that a second hinge pin is formed on the first hinge part, which extends along the hinge axis in a direction opposite to the first hinge pin, with a second hinge sleeve being pivotably mounted on the second hinge pin, which is a second one with the second hinge pin Plain bearing forms, wherein the solid support part is designed for a connection of the first hinge sleeve with the second hinge sleeve. This ensures an advantageous, in particular symmetrical, force transmission between the first hinge part and the second hinge part, so that the hinge arrangement can also be used for high loads, such as those that occur, for example, in furniture fittings or waste bins.
Bevorzugt ist vorgesehen, dass das erste Scharnierteil von einer längs der Scharnierachse erstreckten Längsbohrung durchsetzt ist, in der eine Federeinrichtung aufgenommen ist, die jeweils endseitig mit dem ersten Scharnierzapfen und mit der zweiten Scharnierhülse verbunden ist. Die Aufgabe der Federeinrichtung besteht darin, eine Vorzugsstellung für das zweite Scharnierteil gegenüber dem ersten Scharnierteil zu bestimmen. Hierzu ist vorgesehen, dass die Federeinrichtung bei einer Relativbewegung des ersten Scharnierteils gegenüber dem zweiten Scharnierteil eine Veränderung einer inneren Federspannung erfährt, womit in Abhängigkeit von einer Richtung der Schwenkbewegung eine Abgabe von Energie durch die Federeinrichtung oder eine Speicherung von Energie in der Federeinrichtung stattfindet. Durch die Anordnung der Federeinrichtung in der Längsbohrung des ersten Scharnierteils kann eine besonders kompakte Bauform für das erste Scharnierteil verwirklicht werden. Darüber hinaus ist es vorteilhaft, wenn eine Mittelachse der typischerweise als Wendelfeder ausgebildeten Federeinrichtung koaxial zur Scharnierachse angeordnet ist, da hiermit eine symmetrische Krafteinleitung auf die Federeinrichtung ermöglicht wird.It is preferably provided that the first hinge part is penetrated by a longitudinal bore extending along the hinge axis, in which a spring device is accommodated, each end of which is connected to the first hinge pin and with the second hinge sleeve is connected. The task of the spring device is to determine a preferred position for the second hinge part compared to the first hinge part. For this purpose, it is provided that the spring device experiences a change in an internal spring tension when the first hinge part moves relative to the second hinge part, whereby energy is released by the spring device or energy is stored in the spring device depending on a direction of the pivoting movement. By arranging the spring device in the longitudinal bore of the first hinge part, a particularly compact design for the first hinge part can be achieved. In addition, it is advantageous if a central axis of the spring device, which is typically designed as a coil spring, is arranged coaxially to the hinge axis, since this enables a symmetrical introduction of force onto the spring device.
Bei einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass zwischen dem ersten Scharnierzapfen und der ersten Scharnierhülse eine Gleithülse angeordnet ist und/oder dass zwischen dem ersten Scharnierzapfen und der ersten Scharnierhülse ein, insbesondere in einem in der ersten Scharnierhülse festgelegten ersten Trägerring, aufgenommener Dichtring, angeordnet ist. Die Aufgabe der Gleithülse besteht darin, eine Gleitreibung zwischen einer ersten Außenoberfläche des ersten Scharnierzapfens und einer ersten Innenoberfläche der ersten Scharnierhülse gering zu halten. Vorzugsweise ist vorgesehen, dass das erste Scharnierteil und das zweite Scharnierteil jeweils aus einem metallischen Werkstoff, insbesondere Aluminium, hergestellt sind. Ferner ist vorgesehen, dass die Gleithülse aus einem Kunststoffmaterial wie beispielsweise Polyoxymethylen (POM), das unter anderem auch unter dem Handelsnamen Delrin vertrieben wird, hergestellt ist, womit eine Lagerreibung zwischen dem ersten Scharnierzapfen und der ersten Scharnierhülse in einem engen Intervall vorgegeben werden kann. Ergänzend oder alternativ ist vorgesehen, dass ein Dichtring zwischen dem ersten Scharnierzapfen und der ersten Scharnierhülse angeordnet ist, der den Arbeitsraum in einer vom Abschlussdeckel abweisenden Axialrichtung abdichtet, damit in diesem Bereich kein Austreten von Dämpfungsflüssigkeit aus dem Arbeitsraum möglich ist. Vorzugsweise ist vorgesehen, dass der Dichtring, der insbesondere als O-Ring ausgeführt sein kann, in einer umlaufenden Nut eines in der ersten Scharnierhülse festgelegten ersten Trägerrings aufgenommen ist. Dabei ist der Trägerring beispielsweise abdichtend in die Scharnierhülse eingepresst und weist die umlaufende Nut an seiner Innenoberfläche auf. Die Aufgabe des Trägerrings besteht darin, eine vorteilhafte Anlagefläche für den Dichtring bereitzustellen, ohne dass diese Anlagefläche in aufwendiger Weise an der Innenoberfläche der ersten Scharnierhülse gefertigt werden muss.In an advantageous development of the invention, it is provided that a sliding sleeve is arranged between the first hinge pin and the first hinge sleeve and/or that a sealing ring is accommodated between the first hinge pin and the first hinge sleeve, in particular in a first carrier ring fixed in the first hinge sleeve. is arranged. The task of the sliding sleeve is to keep sliding friction between a first outer surface of the first hinge pin and a first inner surface of the first hinge sleeve low. It is preferably provided that the first hinge part and the second hinge part are each made of a metallic material, in particular aluminum. Furthermore, it is envisaged that the sliding sleeve is made from a plastic material such as polyoxymethylene (POM), which is also sold under the trade name Delrin, among others is, with which bearing friction between the first hinge pin and the first hinge sleeve can be specified in a narrow interval. Additionally or alternatively, it is provided that a sealing ring is arranged between the first hinge pin and the first hinge sleeve, which seals the working space in an axial direction facing away from the end cover, so that no escape of damping fluid from the working space is possible in this area. It is preferably provided that the sealing ring, which can in particular be designed as an O-ring, is received in a circumferential groove of a first carrier ring fixed in the first hinge sleeve. The carrier ring is, for example, pressed sealingly into the hinge sleeve and has the circumferential groove on its inner surface. The task of the carrier ring is to provide an advantageous contact surface for the sealing ring without this contact surface having to be manufactured in a complex manner on the inner surface of the first hinge sleeve.

Da die zweite Scharnierhülse 27, wie nachstehend noch näher beschrieben wird, dem zweiten Scharnierteil 5 zugehörig ist, wird bei einer Schwenkbewegung des zweiten Scharnierteils 5 gegenüber dem ersten Scharnierteil 4 eine Torsionsbewegung in die Wendelfeder 19 eingeleitet, wodurch in Abhängigkeit von der Richtung der Schwenkbewegung entweder eine Freigabe von gespeicherter Federenergie aus der Wendelfeder 19 oder eine Speicherung von Federenergie in die Wendelfeder 19 stattfindet.Since the

Vorzugsweise ist vorgesehen, dass das erste Scharnierteil 4 und die zweite Scharnierhülse 27 jeweils aus einem metallischen Werkstoff, insbesondere Aluminium, hergestellt sind und dass die zweite Gleithülse 32 aus einem gestaltfesten Kunststoffmaterial hergestellt ist.Purely as an example, it is provided that the
Der Aufbau des ersten Gleitlagers 2 unterscheidet sich vom soeben beschriebenen Aufbau des zweiten Gleitlagers 3 dadurch, dass das erste Gleitlager 2 eine nachstehend näher beschriebene Dämpfungseinrichtung 12 aufweist. Die Aufgabe der Dämpfungseinrichtung 12 besteht darin, eine Schwenkbewegung zwischen dem ersten Scharnierteil 4 und dem zweiten Scharnierteil 5 zu bremsen und somit eine komfortable und gefahrlose Schwenkbewegung eines am zweiten Scharnierteil 5 angebrachten, nicht dargestellten zweiten Einrichtungsteils gegenüber einem ebenfalls nicht dargestellten ersten Einrichtungsteil zu ermöglichen, an dem das erste Scharnierteil 4 festgelegt ist.The structure of the first plain bearing 2 differs from the structure of the second plain bearing 3 just described in that the first plain bearing 2 has a damping device 12 described in more detail below.

Beispielhaft sind der erste Axialvorsprung 55 und der zweite Axialvorsprung 56 punktsymmetrisch zu einem Symmetriepunkt ausgebildet, der sich als Schnittpunkt zwischen der Scharnierachse 6 und der ersten Axialstirnfläche 54 ergibt.

Nachstehend wird die Funktionsweise der Dämpfungseinrichtung 12 anhand der Wechselwirkung zwischen dem ersten Axialvorsprung 55, der ersten Nut 62 sowie einer nicht näher dargestellten Dämpfungsflüssigkeit beschrieben, wobei diese Funktionsweise in gleicher Weise auch für die Wechselwirkung zwischen dem zweiten Axialvorsprung 56, der zweiten Nut 63 und der nicht näher dargestellten Dämpfungsflüssigkeit zutrifft.The mode of operation of the damping device 12 is described below based on the interaction between the first
Die erste Nut 62 weist eine umlaufende erste Seitenwand 65 auf, die einen ersten, nach außen weisenden Wandabschnitt 66 sowie einen zweiten, nach innen ragenden Wandabschnitt 67 umfasst, wobei beide Wandabschnitte 66, 67 jeweils eine kreisbogenabschnittsförmige Profilierung in einer quer zur Scharnierachse 6 ausgerichteten und der Darstellungsebene der Figur 4 entsprechenden Querschnittsebene aufweisen.

Rein exemplarisch ist der Abschlussdeckel 82 rotationssymmetrisch zur Scharnierachse 6 ausgebildet und umfasst einen von der beispielhaft eben ausgebildeten und quer zur Scharnierachse 6 ausgerichteten Innenseite 83 längs der Scharnierachse 6 erstreckten Gewindezapfen 84, der mit einem nicht bezeichneten Außengewinde versehen ist. Das Außengewinde des Gewindezapfens 84 ist zum Eingriff in eine Gewindebohrung 85 vorgesehen, die koaxial zur Scharnierachse 6 in den Steg 61 eingebracht ist und die zusammen mit dem Gewindezapfen 84 eine Schraubverbindung 86 bildet. Mit dieser Schraubverbindung 86 kann einerseits eine Festlegung des Abschlussdeckels 82 an der ersten Scharnierhülse 26 vorgenommen werden. Andererseits ermöglicht diese Schraubverbindung 86 eine Einstellung eines Abstands 90 zwischen der Innenseite 83 des Abschlussdeckels 82 und einer ersten Stirnfläche 37 der ersten Scharnierhülse 26. Durch diese Abstandseinstellung erfolgt auch eine Einstellung eines Querschnitts des vierten Bewegungsspalts 77, womit die Eigenschaften der Dämpfungseinrichtung 12 beeinflusst werden können.Purely as an example, the
Die Wirkungsweise der Dämpfungseinrichtung 12 beruht darauf, dass die in der
In den Arbeitsraum 91 greift zum einen der erste Axialvorsprung 55 ein, zum anderen ist dieser Arbeitsraum 91 vorzugsweise vollständig mit einer nicht dargestellten Dämpfungsflüssigkeit, beispielsweise einem mineralischen oder synthetischen Öl, insbesondere einem Silikonöl, gefüllt. Dementsprechend erfolgt während einer Relativbewegung zwischen dem ersten Scharnierteil 4 und dem zweiten Scharnierteil 5 auch eine Relativbewegung des ersten Axialvorsprungs 55 gegenüber der ersten Nut 62. Da der Arbeitsraum 91 vorzugsweise vollständig mit der Dämpfungsflüssigkeit gefüllt ist, ist es zur Durchführung dieser Relativbewegung zwischen dem ersten Axialvorsprung 55 und der ersten Nut 62 erforderlich, dass die Dämpfungsflüssigkeit vom ersten Axialvorsprung 55 aus einem ersten größenvariablen Arbeitsraumabschnitt 92 verdrängt wird und in einen zweiten größenvariablen Arbeitsraumabschnitt 93 strömen kann. Da die Dämpfungsflüssigkeit hierbei lediglich durch die Bewegungsspalte 74 bis 77 strömen kann, die für die Dämpfungsflüssigkeit einen erheblichen Strömungswiderstand bereitstellen, wird die gewünschte Bedämpfung der Relativbewegung zwischen dem ersten Scharnierteil 4 und dem zweiten Scharnierteil 5 gewährleistet.On the one hand, the first
Durch die Einstellung des Abstands 90 wird einerseits die elastische Deformation des Dichtrings 87 verändert. Andererseits wird hierdurch der Querschnitt für den vierten Bewegungsspalt 77 beeinflusst, so dass ein insgesamt für ein Strömen der Dämpfungsflüssigkeit zur Verfügung stehender Querschnitt, der sich anhand der einzelnen Querschnitte der Bewegungsspalte 74 bis 77 ermitteln lässt, variiert werden kann, um die gewünschte Dämpfungswirkung für die Scharnieranordnung 1 zu beeinflussen.On the one hand, by adjusting the
