Abstract

A door handle arrangement has a bearing member (14) with a door handle bore (43) for mounting to the door leaf and also a door handle with a neck (11) which is axially inserted into the door handle bore (43). Conical segments (18) which are arranged around the neck (11) of the door handle are provided between the bearing member (14) and the neck (11) of the door handle. The conical segments have a conical outer peripheral surface and/or a conical inner peripheral surface, which cooperates in axially sliding manner with a corresponding complementary shaped counter-surface of the bearing member (14) and/or of the rotary spigot (12), and are biased axially by springs (15) in a direction which reduces the diameter of the opening which receives the neck of the door handle.

Description

The invention relates to a lever handle arrangement with a bearing part to be fastened to the door leaf, having a door lever bore, an axially inserted door lever neck and radially movable bearing means arranged between the bearing part and the door lever neck for diameter tolerances and / or centering errors and / or misalignment compensating for the rotatable mounting of the door lever on Bearing part.

To compensate for the misalignment, oscillating joint bearings are known. Another known bearing (DE-PS 19 07 434, DE-PS 24 12 061) is adjustable in such a way that both diameter errors and centering errors as well as misalignments between the pivot pin of the handle neck and the bearing part can be compensated. However, this known bearing has the disadvantage that a precise setting must be made by the fitter during assembly, if on the one hand a play-free mounting of the lever handle is to be ensured and on the other hand the clamping friction between the pivot pin and the bearing part should not be too great.

In contrast, the object of the present invention is to provide a lever handle arrangement of the type mentioned at the outset in which a play-free, yet low-friction bearing of the handle neck is automatically ensured, even when the handles used have certain diameter tolerances and through certain misalignment and misalignment errors occur due to assembly-related misalignment.

To achieve this object, the invention provides that the radially movable bearing means consist of cone segments arranged around the pivot of the pusher neck, which have at least one conical outer surface, preferably an outer circumferential surface and / or at least one conical inner surface, preferably a conical inner circumferential surface at least one corresponding, complementarily designed counter surface of the bearing part and / or of the pivot pin are axially slidably arranged and axially acted upon by springs in the direction of a door handle receptacle opening diameter reduction, the non-conical outer or inner circumferential surface and the mating surface of the bearing part resting thereon and / or the trunnion are circular cylindrical.

In this way it is ensured that the cone segments always create a play-free mounting surrounding the pivot pin on all sides.

In the extreme case, a single cone segment would also be sufficient for play-free storage, if this is desired for certain lever handle arrangements for reasons of simplification. According to the invention, the cone segments are held and guided such that they can preferably not fall axially forward either radially inwards or in their position corresponding to the smallest diameter.

It is particularly preferred here if the cone angle and the surface properties of the cone surfaces sliding against one another are selected such that the cone segments, when not in contact with the inner and outer circumferential surfaces, are inserted from the preferably weak springs into the cone gap until the inner and outer circumferential surfaces are in contact are that, however, radial forces exerted by the pivot are not able to axially shift the cone segments. This embodiment is particularly advantageous because self-locking is achieved here, which enables a particularly low-friction, but nevertheless radially fixed, play-free mounting of the lever handle neck. The cone angle is here moves between 10 and 20 °. In order to achieve the greatest possible radial compensation, the cone angle should be as large as is just compatible with achieving secure self-locking.

In order to achieve uniform storage all round, several and preferably four individual cone segments should be evenly distributed over the circumference. In particular, it is provided here that each individual cone segment extends over an angle of 40 to 80 °, preferably 50 to 70 ° and in particular approximately 60 °.

It is particularly important if the cone gap opens from the front of the bearing part to the rear surface.

In this way it is ensured that a pusher neck inserted from the front moves the cone segments backwards in the direction of the door leaf until the pivot receptacle defined by the inner peripheral surfaces of the cone segments has reached the required diameter. Then the pivot penetrates into the lever handle receptacle and is enclosed by the cone segments on all sides in the sliding seat without play.

In order to facilitate the insertion of the pivot of the handle neck, a further embodiment is designed in such a way that the pivot of the handle neck has a chamfer on its insertion end face, by means of which the cone segments pushed out onto the narrowest door handle receptacle opening diameter during the axial insertion of the pivot pin can be pushed apart to the required diameter. Another particularly preferred alternative is in

Claim 3 defined, wherein this cone in particular prevents the cone segments from falling out radially inwards.

According to a particularly preferred embodiment, to ensure that the inner circumferential surfaces of the cone segments lie evenly on the pivot of the pusher neck in the event of misalignment form the cone segments on the inner circumferential surface on an axial extension, such that in the event of misalignment, the inner surface of the cone segments rests completely on the outer circumferential surface of the pivot and the cone segments are partially lifted off on their outer circumferential surface due to the misalignment.

So that the cone segments are not carried along in the circumferential direction by the small but still present frictional forces when the door handle is operated normally, the cone segments should be axially displaceable, but fixed in the circumferential direction on the bearing part.

In the event of failure of one or more clamping segments e.g. by breaking the spring or breaking it to retain a certain, playful mounting of the door handle and to avoid a strongly off-center or crooked insertion of the handle, according to a further development of the invention, segments of the bearing part which are stationary between the cone segments spring back radially somewhat outwards intended.

So that the cone segments assume a clear starting position even with preloaded axial springs, axial stops should be provided on the side of the cone segments facing away from the springs.

A further advantageous embodiment of the invention is designed in such a way that openings are provided in the front end face of the bearing part, through which the cone segments can be axially loaded and displaced by means of a pin or screwdriver if the cover cap is removed but the pusher neck is inserted. In this way, the adapter can be adjusted by axially displacing the cone segments from the front end face of the bearing part solution of the door handle position to the various errors.

Even if the sliding surface on the pivot of the pusher neck can be conical, it is preferred if the pivot and the inner circumferential surface of the cone segments are circular cylindrical and only the outer circumferential surface of the cone segments and the associated counter surface of the bearing part are conical. In this way, conventional door handles with circular cylindrical pivot pin on the handle neck can be used for the bearing part according to the invention.

For space-saving storage of the springs, it is expedient if the cone segments have axial blind bores in which helical compression springs are arranged as springs.

To support the springs on the bearing part, it is provided that the springs are supported on the side axially facing away from the cone segments on an annular plate attached to the rear surface.

An embodiment which is particularly suitable for practical implementation is characterized in that the cone segments only have partial circumferential surfaces at their two end regions lying in the circumferential direction, each of which cooperate with a corresponding flank of two laterally arranged oblique grooves in the bearing part. It should in particular be provided that the partial circumferential surfaces are formed on lateral sliding webs of the cone segments, which are guided in the sliding grooves in the sliding fit. It is further expedient if a free space is provided in the bearing part radially outside each cone segment, into which a spring receiving projection arranged between the sliding webs extends. In this way the cone segments along their ge _- out on all sides clearly shifting entire length.

To ensure automatic lubrication even during long-term operation, the cone segments in the sliding surfaces can have bores as grease deposits.

Optimal adaptation, particularly to misalignment and misalignment, is ensured in a particularly advantageous manner in a single version of the cone segments, because each cone segment can assume a different axial position.

However, it is also possible for the cone segments to be combined into a cone ring provided with a circumferential slot. In this case, the cone ring must be designed to be so elastic that it can easily withstand the twists that occur with misalignment and misalignment.

The twisting of the cone ring is considerably facilitated if the cone ring between adjacent cone segments is provided with axial slots that are open on one side. It is particularly advantageous if the axial slots are alternately open on one and the other end face of the conical ring.

If the bearing part is provided with a cover cap, care must also be taken to compensate for different radial positions of the lever handle in this area.

If it is a lever handle arrangement with a cover cap which covers and preferably snaps on the bearing part and which has a door handle through hole in alignment with the door handle bore of the bearing part, the pivot pin on the door handle neck having the same part as the projecting part of the door handle neck, the invention looks like this a particularly preferred embodiment before that the locking surfaces of the top cap are formed with so much radial overlap that the top cap on the bearing part is radially displaceable by the amount of radial compensation of the cone segments on the bearing part, the door handle neck through hole in the top cap in diameter essentially that Corresponds to the outer diameter of the pusher neck or the pivot pin.

On the other hand, it is a door handle arrangement with a cover cap that covers and preferably snaps on the bearing part, which has a door handle through hole in alignment with the door handle bore of the bearing part, the pivot pin of the handle neck having a smaller diameter than the part of the handle neck protruding axially from the bearing part and over one radial ring step merges into the part of the pusher neck projecting axially from the bearing part, the invention provides for radial compensation in the area of the cover cap that the cover cap is radially fixed on the bearing part and the door handle passage hole in the cover cap has a larger diameter than the radial compensation of the cone segments Has pivot, the ring should cover the door handle through hole at each radial position of the handle neck.

Of particular importance in the invention is therefore the self-locking of the cone segments, thereby avoiding the fact that the relatively weak springs, which preload the cone segments axially, have to absorb bearing forces. Relatively weak springs for this purpose are also desirable so that no excessive braking torque is exerted on the pusher neck or the pivot pin formed thereon, which would lead to the pusher being stiff. To reduce the braking effect between the pivot and the bearing part should in addition, the friction between the bearing neck of the pusher neck and the cone segments should be as small as possible. This can be achieved by appropriate selection of materials (e.g. polyamide for the pusher neck, polyoxymethylene for the bearing ring) and favored by additional lubrication. Grease deposits can be provided in the sliding surfaces of the cone segments for permanent lubrication.

If the cone segments are combined to form a cone ring, it is expedient if this ring is composed in layers of individual slotted disks or of ring segments which are movable relative to one another, for example in the manner of a metallic watch strap.

So that when the cone segments are combined to form a cone ring, it cannot twist, e.g. a radial projection can be provided in the conical receiving bore of the bearing part, which engages radially in the ring slot of the conical ring.

Corresponding axial projections ensure, according to the invention, that the cone segments are in full contact with the constantly moving sliding surfaces on the pivot. Optionally or additionally, the axial springs are arranged as far as possible on the outside of the cone segments and / or inclined according to the cone angle.

If, according to the one preferred embodiment, the cone segments are guided in inclined, for example T-shaped grooves, the slider-like cone segments are given some play in the grooves perpendicular to the inclined surfaces so that they tilt slightly when the lever is misaligned and thus completely overlap the pivot pin of the lever neck can put on. By extending the part of the cone segment facing the pivot of the pusher neck This can be brought about in the parts guided in the grooves, as has been generally described above in connection with the cone segments.

It is possible to arrange cone segments designed as individual parts close together so that practically the entire inner surface of the bearing consists of cone segments lying next to each other. Optionally, it is possible to allow segments of the bearing part to protrude radially between the slides, which limit the adjustability of the bearing and thus form a reserve bearing.

If openings are provided in the end face of the bearing part, through which the cone segments are accessible, so that with the cover cap removed, using a finger or a screwdriver, e.g. can be pushed back towards the door surface, so it is possible to temporarily release the handle neck to correct its centering or alignment.

According to FIGS. 1 and 2, a rosette 14 forming the bearing part of a lever handle arrangement has fastening bores 36 as well as fitting pins 37 surrounding it, projecting towards the door leaf (not shown), which are inserted into corresponding fitting bores of the door leaf. For assembly, the rosette 14 is placed with its rear surface 17 on the door leaf, whereupon the rosette 14 is finally fixed on the door leaf by means of screws guided through the fastening holes.

In the middle, the rosette is provided with a door handle bore 43 which is delimited by an inner wall of the bearing part 14 consisting of individual segments 20. The diameter of the circumferential wall formed by the circular cylinder segments 20 is so much larger than the diameter of the pivot pin 12 of the neck 11 to be used there of a lever handle shown only broken off in FIG. 2 that the pivot pin 12 is supported within the segments 20 with clear play on all sides. The play between the segments 20 and the pivot 12 in the radial direction is so great that it allows all occurring diameter variations due to manufacturing tolerances as well as all conceivable misalignment and misalignment between the door handle and the rosette 14 to accommodate.

In order to create a play-free, low-friction pivot bearing of the pivot pin 12 in spite of this oversizing of the door handle bore 43, the bearing part 14 has conical ring gaps 16 between the segments 20 in the circumferential direction, which, like the segments 20, run concentrically to the door handle axis 44, but one with respect to the segments 20 have radially outwardly offset conical outer circumferential surface, the conical ring gap 16 expanding from the side of the door handle to the rear surface 17 of the rosette 14.

Cone segments 13 are inserted axially displaceably in the cone ring gap 16, the conical outer circumferential surface of which extends complementarily to the inner circumferential surface of the cone ring column 16.

Radially on the inside, the cone segments have circular cylindrical inner sliding surfaces 41, the circular cylindrical shape of which are complementary to the circular cylindrical design of the pivot pin 12.

The cone segments 13 are shorter in the axial direction than the thickness of the rosette 14 and are each biased from behind by an axially arranged helical compression spring 15 into the position shown in FIG. 2 at the beginning of the door handle bore 43. The spring is located in axial bores 25 on the back of the cone segments 13 and is supported with its rear end on a ring plate 26 which is fastened in the rear surface 17 of the rosette 14 and projects radially inwards only to such an extent that the Square pin, not shown, can pass freely.

In order to limit their movement towards the front of the rosette 14, the axially biased in the direction of the door handle cone segments 13, the conical annular gap is limited axially 16 on the front side by radially over the cone segments 13 projecting axial stops 21 partially, so that strength in the group consisting of _F. 1, 2 apparent position when not inserted pivot pin 12, the cone segments by the springs 15 to the _A xialanschlägen 21 come to rest. In this position, the inner sliding surfaces 41 of all four cone segments 13 arranged on the circumference at uniform intervals define a minimum diameter Dmin for receiving a pivot 12 of a door handle, which has the smallest diameter within the manufacturing tolerances.

If such a pivot pin 12 is inserted into the bore defined by the inner sliding surfaces 41, it is rotatably guided without play.

The axial stops 21 should not project further in the radial direction inward than the segments 20 of the rosette 14 forming a reserve bearing.

3, a pivot 12 with a larger diameter than the diameter Dmin is axially inserted into the door handle bore 43, a chamfer 18 provided at the rear end of the pivot 12 abuts the front annular and flat end faces of the cone segments 13 and displaces them towards the rear surface 17.

Here, the cone segments 13 under the influence of the forces exerted on the chamfer 18
pressed backwards so that the cone segments 13 slide along the conical inner circumferential surface of the cone ring gap 16 and the radial distance of the inner sliding surfaces 41 from the axis of rotation 44 increases, that is to say that the actual diameter of the door handle bore 43 defined by the inner sliding surfaces 41 is continuously increasing. This displacement process of the cone segments 13 continues until the diameter defined by the inner sliding surfaces 41 reaches the value of the outer diameter of the pivot pin 12 of the inserted push neck 11. Now the pivot pin 12 can enter the space between the cone segments 13 and finally assume the position shown in FIG. 3.

The door handle is now stored in the rosette 14 without play.

The cone segments 13 are also extended by sliding webs 30 on both sides in the circumferential direction, which are formed obliquely in accordance with the cone gap 16. The slide bars 30 are mounted in oblique grooves 29 in a sliding fit or with a certain _K ippausgleich ermöglichendem game, which are / is provided in the radial surfaces 10 at the circumferential ends of the conical annular gap. According to the invention, the cone angle of the cone ring gap 16 should be so small that self-locking occurs to the extent that radial forces are exerted on the cone segments 13 via the pivot pin 12. In this case, a displacement of the cone segments 13 in the direction of the rear surface 17 should also be excluded when using very weak springs 15. Due to this design, the friction between the inner sliding surfaces 41 and the pivot pin 12 can be kept very low, while on the other hand a radial deflection of the pivot pin 12 is excluded even with strong forces acting on the lever handle.

Before the door handle is inserted into the rosette 14, a cover cap 23 has been snapped onto the rosette 14 by means of latching surfaces 35 provided on the circumference.

The cover cap 23 has a central door handle through hole 38 which has a diameter of the pivot 12 which is so much larger than the smallest possible that the pivot does not abut the inner edge of the hole 38 in the case of all possible diameter variations, misalignment and misalignment . This type of play compensation between the door handle neck 11 and the top cap 23 is preferred if, as can be seen from FIGS. 2 and 3, the pivot pin 12 has a smaller diameter than the part of the handle neck 11 projecting axially from the rosette 14 a radial annular step 39 is created, which rests on the front of the top cap 23 and completely covers the clear annular gap between the pivot 12 and the peripheral edge of the door handle through hole 38 to the front. The prerequisite is that the annular step 39 has such an extent in the radial direction that the lever handle through hole 38 is covered in any case within the scope of the predetermined compensation. In all other figures, the same reference numerals designate corresponding parts as in FIGS. 1 to 3.

FIG. 4 shows the same embodiment as FIGS. 1 to 3, but the central axis 44 of the pusher neck 11 is offset to the right by approximately 0.5 mm relative to the central axis 44 'of the rosette 14 in FIG. 4. The door handle arrangement according to the invention readily compensates for this misalignment in that the cone segment 13, to which the pivot pin 12 is offset somewhat, deviates further in the axial direction than the diametrically opposite cone segment 13.

Although the two diametrically opposite cone segments 13 of the pivot 12, which are not shown in FIG. 4, are no longer exactly exactly circular, these relatively small deviations can be caused by the elasticity of the pivot 12 and the cone segments 13 or their mounting on the inner circumferential surface of the cone ring gap 16 can be balanced easily.

5, the central axis 44 of the lever handle is tilted by a slight angle of approximately 2 to 3 ° with respect to the central axis 44 'of the rosette 14, specifically to the right in FIG. 5. Here, too, the cone segments 13, which move more or less far in the axial direction, provide the necessary compensation, with play-free guidance of the pivot pin 12 still being ensured. A slight partial lifting of the sliding surfaces on the pivot pin 12 from the inner sliding surfaces 41 is at least partially compensated for on the one hand by elastic compliance of the components, which are preferably all made of plastic, and does not question the function of the lever handle mounting. On the other hand, the cone segments 13 can partially lift off somewhat from the circumferential surfaces, so that overall a largely complete radial support of the pivot pin 12 is still ensured even with maximum misalignment.

In the exemplary embodiment according to FIG. 6, the helical compression springs 15 acting on the cone segments 13 and the bores 25 receiving them are oblique to the door handle bore arranged, namely at the angle of the conical inner circumferential surface of the cone ring gap 16. As a result, the force acting on the cone segments 13 is exerted exactly in the direction of movement of the cone segments 13.

In addition, the embodiment according to FIG. 6 has the peculiarity that the cone segments 13 have axial extensions 19 in the direction of the door leaf, not shown, which are in sliding guide engagement with the outer peripheral surface of the pivot 12 of the lever handle neck 11. The axial extensions 19 protrude clearly beyond the rear abutment of the spring 15 in the area of the rear surface 17 of the rosette 14, as a result of which a lever arm is created on the side of the cone segments 13 facing away from the lever handle insertion side, which lever arm ensures misalignment when a lever neck 11 is inserted, that the inner sliding surfaces 41 are in complete abutment with the outer circumferential surface of the pivot pin 12, while the conical outer circumferential surfaces of the cone segments 13 partially lift off from the conical inner circumferential counter surfaces to compensate for the misalignment. This results in annular gussets 45 in this area, which can be seen in FIG. 6.

Since the axial extensions 19 protrude slightly to the rear over the rear surface 17 of the rosette 14, a cover and support pot 40 is concentrically attached to the rear surface 17 of the rosette 14, the peripheral flange of which is flush with the rear surface 17, which, however, is somewhat central in the direction of the door leaf protrudes where a corresponding rear guide bore for receiving the cover and support pot 40 is to be provided. This design also has the advantage that the pivot 12 of the lever handle neck 11 is rotatably guided over a greater axial length.

Furthermore, the embodiment according to FIG. 6 differs from the previous embodiments insofar as the pivot 12 of the lever handle neck 11 does not have a reduced diameter compared to the above part. The lever handle neck 11 thus merges smoothly into the pivot pin 12 supported by the cone segments 13. For this reason, it is not acceptable for optical and pollution reasons to provide the lever handle through hole 38 in the top cap 23 with the enlarged diameter required to compensate for all errors. Rather, in the exemplary embodiment according to FIG. 6, the door handle through hole 38 has a diameter which, given the largest diameter of the pivot pin 12, allows just a non-contact passage of the pivot pin 12 through the hole 38. In order to provide radial compensation in the event of misalignment and misalignment, the latching surfaces 35 are provided with so much radial play according to the invention that the entire top cap 23 receives such a play in the radial direction as is necessary to adapt to the occurring misalignment and misalignment .

For this purpose, the latching surfaces 35 have a sawtooth-like mutual engagement, annular support planes running perpendicular to the axis 44 being provided on the rosette 14 or the top cap 23. The annular support plane on the top cap 23 has a significantly larger diameter than the cooperating ring support surface on the rosette 14, thereby ensuring a radial play of the top cap 23, indicated at 46 in FIG. 6, relative to the rosette 14. 6, the top cap 23 is in the right end position of the available radial play relative to the rosette 14.

The ring support surfaces running parallel to the door leaf must overlap to such an extent that they are still securely locked in place even in the extreme radial relative displacement shown in FIG. 6.

7 to 12, the bearing part of the door handle arrangement according to the invention is an elongated door plate 14, which consists of a plastic lower part 14 "and a front metallic cover plate 14 '. Around the central door handle bore 43, specially designed cone segments 13 are arranged, specifically as - in the previous embodiments - four pieces at an angle of 90 ° each.

The space provided for accommodating the helical compression springs 15 and certain guide parts of the door plate 14 is extended in the direction of the door leaf behind the rear surface 17 of the door plate 14 by means of a cover and support pot 40. A corresponding hole around the square pin in the door leaf, which is not shown, is again provided for receiving the cover and support pot 40.

According to FIGS. 9 to 11, each cone segment 13, which again extends at an angle of somewhat less than 90 °, on the side facing away from the inner sliding surface 41 has a spring receiving projection 32 which contains the axial bore 25 for accommodating the springs 15. The bore 25 is closed towards the front and open to the rear surface 17 of the door plate 14.

On both circumferential sides of the spring receiving projection 32, oblique sliding webs 30 are formed corresponding to the cone angle of the conical ring gap 16, which have partial circumferential surfaces 27 on the radially outer side, which interact with the corresponding counter-inner surfaces 28 on the door plate.

The partial circumferential surfaces 27 are not curved in the circumferential direction, but run parallel to a secant of the door handle bore.

On the radially inner side of the partial circumferential surfaces 27, the sliding webs 30 also have sliding surfaces 47 which interact with corresponding counter surfaces on the door plate 14.

9 to 11, two lubricant receiving holes 33 are provided in the inner sliding surface 41.

13 The cone segment / according to FIGS. 9 and 10 cooperates with a door plate 14, as is particularly clearly shown in FIGS. 12, 13 except in FIGS. 7, 8. On both sides of the circular cylinder segments 20 which define the largest possible diameter of the door handle bore 43 and which project axially clearly beyond the rear surface 17 of the door plate 14 into the cover and support pot 40, obliquely offset grooves 29 are provided, into which the sliding webs 30 9 to 11 engage in the sliding fit. The oblique grooves 29 run from the front surface to the rear surface 17 of the door plate 14 in the sense of a displacement of the cone segments 13 radially outwards.

In the circumferential direction, two oblique grooves 29 lie opposite each other on a secant at the circumferential distance. Between two mutually assigned, opposite inclined grooves 29 there is a radially outwardly projecting free space 31, in which the spring receiving projections 32 are accommodated.

7, 8, the cone segments 13 with the sliding webs 30 are inserted into the oblique grooves 29, so that they ver as in the previous exemplary embodiments on a conical path corresponding to the oblique grooves 29 can be pushed, the actual diameter defined by the inner sliding surfaces 41 of the door handle bore 43 being changed. The exemplary embodiment according to FIGS. 7 to 12 has the particular advantage that the cone segments are also guided properly in the radially inward direction, so that, for example when the lever handle (FIG. 7) has not yet been used, the cone segments 13 are prevented from falling out radially inwards becomes.

If necessary, however, the sliding webs 30 should be mounted with a certain play in the inclined grooves 29, in order to allow a certain tilting of the inclined segments 13, in particular in the event of misalignments.

The partial circumferential surfaces 28 (FIG. 8) of the oblique grooves 29 which cooperate with the outer circumferential surface 27 of the cone segments 13 are also flat and absorb the radial forces exerted by the pivot pin 12 on the cone segments 13. Self-locking must prevail again between the surfaces 27, 28.

14 and 15, the individual cone segments can also be combined in one piece to form a cone ring 13 ', but a continuous, appropriately dimensioned radial slot 24 is provided at a circumferential point of the cone ring 13' for the purpose of resiliently reducing the cone ring 13 '. 14, the cone ring 13 'is inserted analogously to the cone segments 13 in the cone ring gap 16 of a rosette 14 and is biased forward by the springs 15.

16 and 17, the conical ring 13 'can be provided all around with lubricant receiving bores 33 from the inner sliding surface 41.

Since the conical ring 13 'must not only move axially, but also twist axially, particularly when compensating for misalignment and misalignment, it must be designed to be correspondingly elastic.

The twisting of the cone ring 13 'is facilitated according to FIGS. 18, 19 if the cone ring 13' is radially slotted at certain circumferential intervals, the slits not going through completely, however, and narrow bending webs 48 remaining at their ends. The axial slots 34 are open on the axially opposite side. The cone segments 13 are located between the individual axial slots 34, but are connected to the adjacent cone segments by the narrow bending webs 48 to form the uniform cone ring 13 '. Compared to the arrangement of individual cone segments 13, this embodiment has the advantage that assembly is considerably simplified and that individual cone segments cannot be easily lost.

While in the embodiment according to FIGS. 18, 19 the axial slots 34 all start from the same end face of the cone ring 13 ', in the embodiment according to FIGS. 20, 21 they alternately start from opposite end faces of the cone ring 13'. This favors the possibility of twisting for the cone ring 13 '.

The embodiment according to FIGS. 22 and 23 again has a conical ring 13 ', which, however, consists of individual conical disks 13 "placed flat on top of one another, which are temporarily held together in a relatively movable manner by a rivet 42 which is axially passed through them with play final cohesion takes place after installation by pressing into the cone gap 16 by means of the springs 15.

The continuous radial slots 24 are partially axially aligned, but partially offset from one another in the circumferential direction, which ensures good guidance of the cone ring 13 'within the bearing part 14 is important.

In the entirety of the conical disks 13 ″, the spring receiving spaces 25 are again provided, in which, as in the previous exemplary embodiments, the helical compression springs 15 are accommodated.

The conical ring 13 'according to FIGS. 22, 23 is arranged in the same way as shown in FIG. 14. Twists of the cone ring 13 'according to FIGS. 22, 23 in the event of misalignment and misalignment are, however, due to the division into e.g. five discs 13 ″ lying flat on top of one another are facilitated. The discs 13 ″ can both move parallel to one another and can be slightly separated from one another.

In particular / in the case of a door handle neck 11 having the same diameter up to the pivot 12, it may be expedient to provide openings 22 in the front surface of the bearing part 14, through which the cone segments 13 can be axially acted on by means of a pin or screwdriver in order to move them in the direction of the To move rear surface 17 and temporarily release the pivot pin 12 of the pusher neck radially. As a result, the independent centering or the independent position compensation of the pusher neck 11 can be favored or an existing misalignment or an existing misalignment can be corrected.
