Description

The present invention relates to a hinge device for pivotally connecting a first and a second articulated arm. Such a hinge device can be used in the context of a mirror mount for attaching a mirror to a vehicle, wherein the one hinge arm comprises a fastened to the vehicle base part and the other articulated arm can carry the mirror.

DE 20 2009 013 767 U1 discloses a joint device designed as a latching joint with a first articulated arm and a second articulated arm, which are pivotable relative to each other about a locking joint axis and fixable in locking positions, and a first and a second locking bolt. The first articulated arm comprises two axially spaced, mutually facing bearing surfaces. The second articulated arm comprises a bearing block with axially opposite ends, on which mutually facing counter bearing surfaces are formed. One of the bearing surfaces acts with one of the abutment surfaces and the other of the bearing surfaces interacts with the other of the abutment surfaces. The first locking bolt passes axially through the cooperating one bearing and an abutment surface, and the second locking bolt coaxially passes through the cooperating other bearing and abutment surface. A disadvantage of this hinge device is that two locking bolts are required, which must be introduced and locked independently of each other and in axially opposite directions during assembly of the hinge device by the (one or the other) cooperating bearing and abutment surfaces.

EP 2 331 367 B1 discloses a hinge device in which a hinge formed on a base part bearing block with acting as a bearing collar, cylinder inner bearing surface, formed in the mirror arm thrust bearing with a cylindrical outer wall bearing surface and a secured in the base part locking bolt whose fuse is formed in the base part as a bayonet lock, includes. A disadvantage of this hinge device is that the axial length of the rotary joint, in particular the axial length of the bearing surfaces, compared to the length of the mirror arm is short and the hinge in terms of its construction is essentially a one-point radial bearing, so that the rotary joint by the accuracy of fit the cooperating bearing surfaces has certain radial play between the mirror arm and the base part.

EP 1 886 873 B1 discloses a hinge device with a vehicle mountable base portion on which a bracket is formed with an axial passage opening and a connected via a locking joint with the base part mirror arm with a first bearing arm and a second Lageram, which surround the bearing block axially. In the first bearing arm designed as a latching surface first abutment surface and formed in the second bearing arm designed as a latching surface second abutment surface. The hinge device further comprises a hinge axis component which is arranged in the passage opening of the bearing block and which has at one axial end designed as a latching surface first bearing surface and at the axially opposite end formed as a latching surface second bearing surface. The formed as a latching surface first and second bearing surfaces of the joint axis component cooperate with the latching surface formed as first and second abutment surfaces of the first and second bearing arm. The lateral surface of the hinge axis component forms a cylinder outer wall-shaped bearing surface, and portions of the inner wall surface of the through hole of the bearing block form complementary cylinder inner wall-shaped abutment surfaces. The articulated axle component further comprises a spring element arranged between the two latching surfaces, which biases the first and second bearing surfaces designed as latching surfaces in axially opposite directions against the first and second counter-bearing surfaces of the bearing arms designed as latching surfaces. This eliminates the need for a locking joint zusammenhaltender bolt. A disadvantage of this hinge device is that the axial length of the locking joint, in particular the axial distance of the bearing and abutment surfaces, in comparison to the length of the mirror arm, is quite short and the locking joint determined by the accuracy of the matching bearing and abutment surfaces radial clearance between having the mirror arm and the base part.

EP 0 527 455 A1 describes an exterior mirror mount for commercial vehicles, in which a mirror holding arm is held against both frictionally and positively against a retaining block. Both the frictional engagement and an elastic detent connection acting with the form-fitting connection can be overcome on the mirror arm when a sufficiently high loading moment is exerted in order to permit an evasive movement of the mirror arm.

US 4 728 181 A describes a further exterior mirror holder, in which a mirror holding arm is mounted relative to a holding bracket with an acting in the manner of a shock absorber elastic latching connection. Upon the action of a sufficiently high load moment on the mirror arm, the holding effect of the latching connection can be overcome in order to allow an evasive movement of the mirror arm.

Other types of exterior mirror mounts are z. B. in the US 2008/0310041 A1 or the US 5 137 247 A described.

In this case, at least a part of the end faces can be axially centered and circular or circular segment-shaped.

In the embodiments (A), (B) and / or (C) and in the embodiments (i), (ii) and / or (iii), the centering element can be made in one piece and / or of an elastic material.

The locking bolt passes through the first bearing portion, the bearing bush and the second bearing portion and is at least axially fixed in the locking portion. Characterized in that the first and the second bearing portion are at least spaced by the axial length of the bearing bush disposed therebetween in the axial direction, the pivot is a two-point radial bearing, in which the first articulated arm offset by two in the axial direction, on the one hand by the the first bearing and abutment surfaces and on the other by the second bearing and abutment portions defined axial sections in relation to the second articulated arm is pivotally mounted radially. By this two-point radial bearing radial play of the mirror arm relative to the base part is reduced. The reduction of the radial clearance is greater, the greater the axial distance between on the one hand the cooperating first bearing and abutment portions and on the other hand, the cooperating second bearing and abutment portions. Another advantage arises because only one locking bolt is provided, which passes through the first bearing portion, the bearing bush and the second bearing portion and is axially fixed. The arrangement with only one locking bolt, in contrast to known arrangements with two locking bolts, simpler and faster to assemble.

The two-point bearing formed in the hinge allows the hinge device to have high rigidity and favorable vibration characteristics. By vibrations is meant here the vibrations produced during the driving operation of a vehicle, for example with regard to their frequency vibrations dependent on the engine speed or vibrations resulting from rolling contact of the wheels with the roadway. Due to the two-point mounting, the hinge device is stable and stiff against such vibrations.

The hinge device may be used to pivotally attach a mirror to a vehicle. In this application, the achievable in the joint device high rigidity, stability and backlash also allows with that articulated arm, which is articulated to the vehicle-mounted articulated arm, a wide projection, d. H. to achieve a large length of the hinged articulated arm and a large distance of the mirror carried on the distal portion of the articulated articulated arm of the vehicle outer wall. The achievable large overhang makes the hinge device particularly suitable for truck applications, where the cab is often narrower than a rear body and the high reach, when mounting the hinge device laterally to the cab, makes it possible to bridge this difference in width and to look over the mirror at the rear construction opposite to the direction of travel (backwards).

The high stiffness, stability and backlash of the articulating device also allows the articulating device to be used to support heavy mirrors or heavy mirror systems with large mirror surfaces and / or additional elements integrated in the mirror system, such as lights, direction indicators, mirror adjusters, auxiliary mirrors or antennas can.

Essential components of the hinge device, including the first and second link arms and the latch bolts, may be made of plastic. This and the avoidance of typically made of metal screws allow high corrosion resistance.

The latch bolt may have a proximal end portion, a distal end portion, a bolt head disposed at the proximal end portion, and a bolt shaft extending therefrom toward the distal end portion. Furthermore, the locking bolt may have an annular shoulder formed at the transition from the bolt head to the bolt shaft. This annular shoulder may preferably be formed cone-shaped. The bolt head and the conical annular shoulder can be used for additional centering or for centering at an additional axial position.

The bolt shank may be conical and taper towards the distal end portion. Alternatively or additionally, the Bolt head be conical and taper towards the distal end portion. In particular, the bolt head may have a conical first bolt head section and a conical second bolt head section arranged distally with respect to the first bolt head section, the first and second bolt head sections tapering in the direction of the distal end section. The conical configurations of the bolt shaft and / or the bolt head can, if formed in the first and / or second bearing portion or in the first and / or second end portion of the bearing bush axially corresponding sections complementary bearing surfaces or bearing collars, a more stable radial centering of the bearing sections or cause the bushing and reduce their radial clearance or eliminate.

The locking bolt can be made hollow inside. In this case, at least in sections, an electrical cable may be in the cavity, for example for the electrical supply and / or control of additional components carried by the hinged articulated arm. Alternatively, the locking bolt can be solid. In solid design gives the locking bolt of the hinge device additional stability.

The first bearing portion may comprise a first bearing collar which cooperates with at least a first locking bolt lateral surface portion. The first locking bolt lateral surface section may be arranged in the region of the distal end section of the locking bolt. Thus, the locking bolt in the region of this first locking bolt lateral surface portion with respect to the first bearing collar centered, in particular radially mounted, be. The centering and possibly radial bearing of the locking bolt in the region of the first locking bolt lateral surface portion can reduce or substantially eliminate the radial clearance between the locking bolt and the first bearing portion.

The second bearing portion may comprise a second bearing collar which cooperates with at least one second locking bolt lateral surface portion. The second locking bolt lateral surface portion may be arranged in the region of the proximal end portion of the locking bolt, in particular on the bolt head and / or in the axial vicinity of the bolt head on the bolt shaft of the locking bolt. Thus, the locking bolt in the region of this second locking bolt lateral surface portion with respect to the second bearing collar centered, in particular radially stored, be. The centering and optionally radial bearing of the locking bolt in the region of the second locking bolt lateral surface portion can reduce or substantially eliminate the radial clearance between the locking bolt and the first bearing portion.

The first abutment portion may comprise a third bearing collar which cooperates with at least one third locking bolt lateral surface portion. The third locking bolt lateral surface section can be arranged axially between the first and second bearing section, in particular in the region of the distal end section of the locking bolt, for instance in a distal section of the bolt shaft. Thus, the locking bolt in the region of this third locking bolt lateral surface portion with respect to the third bearing collar centered, in particular radially mounted, be. The centering and optionally radial bearing of the locking bolt in the region of the third locking bolt lateral surface portion can reduce or substantially eliminate the radial clearance between the locking bolt and the first end portion of the bearing bush.

The second abutment portion may include a fourth bearing collar which cooperates with at least a fourth locking bolt lateral surface portion. The fourth locking bolt lateral surface section may be arranged axially between the first and second bearing section, in particular in the region of the proximal end section of the locking bolt, approximately in a distal section of the bolt head and / or in axial proximity to the bolt head on the bolt shaft. Thus, the locking bolt in the region of this fourth locking bolt lateral surface portion with respect to the fourth bearing collar centered, in particular radially mounted be. The centering and optionally radial bearing of the locking bolt in the region of the fourth locking bolt lateral surface portion can reduce or substantially eliminate the radial play between the locking bolt and the second end portion of the bearing bush.

A compensation of dimensional tolerances between the first and / or second articulated arm and the locking bolt can be achieved if the locking bolt has a support layer which covers at least the outer surfaces of the bolt head and the bolt shaft. In this case, the support layer may be formed as a sliding layer, for example made of Teflon. The overlay layer formed as a sliding layer has the effect of reducing the friction between the locking bolt and the bearing collars centering the latter, possibly bearing radially. Moreover, if the overlay has softness greater than the softness of the portions of the latch bolt covered by the overlay layer, the overlay layer may be at least in the regions of the first, second, third, and / or fourth latch bolt surface portions be partially compressed, and thus compensate for dimensional tolerances.

The connection between the locking bolt and the locking portion can be used as a bayonet connection, as a quick-lock connection, as Snap connection and / or be designed as a splint connection. In this case, the connection between the locking bolt and the locking portion may be arranged in the first bearing portion and / or in the second bearing portion of the first articulated arm.

When a locking portion is disposed in or at the first bearing portion, the distal end portion of the locking bolt may be locked in or on the first bearing portion via a first bayonet connection. Alternatively, the distal end portion of the locking bolt by means of a snap connection, a splint connection, in particular by means of a splint, or a Quick-lock connection, in particular by means of a Quick-Lock ring disc, be locked in or on the first bearing portion. This lock can act against axial displacement of the latch bolt toward its proximal end portion. By this locking at its distal end portion of the locking bolt is secured in the hinge device and not lost.

If an alternative or additional locking section is arranged in or at the second bearing section, the proximal end section, in particular the bolt head, of the locking bolt can be locked in or on the second bearing section via a second bayonet connection. Alternatively, the bolt head can be locked in or on the second bearing section by means of a snap connection, a splint connection, in particular by means of a cotter pin, or a Quick-Lock connection, in particular by means of a Quick-Lock ring disk. The locking mechanism on the proximal end section can also act against axial displacement of the locking bolt in the direction of its proximal end section and can secure the locking bolt in the articulation device or not lose it.

The second articulated arm may be biased in the axial direction against the first articulated arm, in particular by means of a spring element. To realize this bias, the hinge device may comprise a spring element having a first and a second end. In this case, the spring element with its first end on the second articulated arm, in particular in the region of the first abutment portion, supported directly or indirectly. Also, the spring element can be supported directly or indirectly with its second end on a support surface formed on the locking bolt. The support surface may be formed in the proximal end portion of the locking bolt, such as the bolt head or the bolt shaft in the vicinity of the bolt head or on the annular shoulder at the transition between the bolt head and the bolt shaft. The spring element can be penetrated by locking bolts, in particular by the bolt shaft. In the case of indirect support of the first and second end can be interposed between the respective end of the spring element and the cooperating support surface, for example made of Teflon, sliding element. The spring element may be formed as a spiral spring, as a plate spring or as a plurality (stack) of disc springs. The bias reduces or eliminates any axial play between the first and second link arms.

The first bearing portion may have a conical inner or outer surface and the first end portion of the bearing bush may have a complementary, conical outer or inner surface. These conical surfaces can cooperate such that the first end portion is supported by the bias on or in the first bearing portion radially and axially substantially free of play. Such an effect is enhanced by the possible bias. For this purpose, in an axial cross-section of the first bearing portion may also have the shape of a cup, in particular a coaxial cup, and the first end portion of the bearing bush in the form of a complementary coaxial cup.

The first and the second articulated arm may be made of plastic or die-cast. The locking bolt may also be made of plastic, in particular by means of a die-casting process. The centering element can be made of an elastic material, such as rubber, made of plastic, and z. B. be formed by means of a die-casting process. If the aforementioned components of the hinge device, namely the first and second articulated arm, the locking bolt and the centering element are made of plastic, the hinge device is inexpensive to manufacture and largely protected against corrosion.

Alternatively to the manufacture of plastic, the locking bolt may be made of a metal, a metal alloy such as brass, or another metallic material. Such a locking bolt gives the joint device special stability and torsional rigidity. The centering element can also be made of a metal, a metal alloy, such as brass, or another metallic material.

The hinge device may be formed as a friction joint. In the embodiment as a friction joint, the first bearing section can be at least partially conical, spherical, cup-shaped with respect to the pivot axis, in the axial cross-sectional profile in the form of a substantially uniform and with respect to the pivot axis substantially symmetrical trapezoid, as at least have three at least partially radially extending, offset in the circumferential direction, in particular evenly distributed, webs arranged, wavy or substantially planar and substantially perpendicular to the pivot axis formed first friction surface. The first abutment portion of the bearing bush may have a second friction surface complementary at least in sections to the first friction surface, which cooperates with the first friction surface. The amount of friction (friction) acting upon relative pivoting of the first and second articulated arms is determined by the magnitude of the preload caused by the spring element and the design of the surface, including grinding, polishing, or applying a sliding layer or braking layer, the friction surfaces.

Alternatively or additionally, the hinge device may be formed as a locking joint. In a first variant of the embodiment as a latching joint, the first bearing section may have a first detent surface formed at least in sections substantially perpendicular to the hinge axis, and the first abutment section of the bearing bush may have a second detent surface formed at least in sections substantially perpendicular to the hinge axis. The second latching surface may be complementary to the first latching surface and cooperate therewith. In a second variant of the embodiment as a latching joint, a lateral surface section of the bearing bush can have a first latching surface, and the first hinge arm can have a surface section formed between the first and second bearing sections, which has a second latching surface. The second latching surface may be complementary to the first latching surface and cooperate therewith. The strength of the effect of the screening with respect to the relative pivoting between the first and the second articulated arm is determined by the strength of the bias caused by the spring element and the configuration of the detents of the detent surfaces, including about a detent depth and a pitch angle of the grid.

According to a second aspect of the invention, there is provided a mirror mount for mounting a mirror to a vehicle. According to the invention, the mirror mount comprises a hinge device according to the first aspect.

According to a third aspect of the invention, there is provided a mirror assembly comprising a mirror head and a mirror mount according to the second aspect.

When using the hinge device for attaching a mirror to a vehicle, the first link arm may be the articulated arm attachable to the vehicle, and the second link arm may have a mirror support portion opposite its hinged end portion supporting the mirror. Alternatively, the second articulated arm may be the articulated arm attachable to the vehicle, and the first articulated arm may include a mirror support portion formed at the end opposite the articulating connection end with the first and second bearing portions and supporting the mirror ,

In both cases, the mirror may be pivotable with respect to the mirror support portion. Furthermore, in both cases, the articulated device can be mounted on a vehicle in such a way that the first bearing section is arranged above the second bearing section or, alternatively, the second bearing section is arranged above the first bearing section.

In both cases, a support arm portion may be formed on the articulated arm supporting the mirror between the end forming the articulation and the mirror support portion, or alternatively two support arm portions extending substantially parallel to each other. In the embodiment with two support arm sections, a wind passage opening may be formed between the two support arm sections to improve the aerodynamic properties (eg aerodynamic drag) and / or the appearance of the articulated arm supporting the mirror.
