Abstract

A door handle arrangement has a door handle (19), a bearing part to be fastened to the door leaf and intended for receiving the door- handle neck (20) and at least one radially movable bolt (11) which is supported on the bearing part and which engages radially into a circumferential groove (22) on the handle neck (20) for the axial fixing of the door handle. To dismount the door handle, the bolt can be lifted radially outwards out of the circumferential groove by means of force engagement and transmission members. The bolt (11) and the force engagement and transmission members (12, 18) also form an integral component of the bearing part (13) in the release position. The force engagement member (12) can be actuated in the release direction through a small orifice (14) in the edge (15) of the cover cap (16) by means of a pin or screwdriver or by means of an inner stop of the cover cap (16) attached rotatably to the bearing part or through a gap, formed by lifting the correspondingly elastic cover cap (16) from the bearing part (13) on one side, by means of a pin or screwdriver or by hand. <IMAGE>

Description

The invention relates to a door handle assembly with a door handle, a bearing part to be fastened to the door leaf, which has a door handle bore for rotatably mounting the lever handle neck having a circumferential groove, and at least one supported on the bearing part, interacting with force application and transmission members, radially movable latch, which for axial fixing of the door handle engages in the circumferential groove and can be lifted radially outward from the circumferential groove for dismantling the door handle by means of the force application and transmission elements, a removable cover cap having a door handle passage hole following the bearing part, the bolt and the force application and transmission elements outside covers.

• Die bereits miteinander verbundenen Teile lassen sich schlechter verpacken und versenden als separate Drücker und Drückerlagerungen. Außerdem hat der Händler eine größere Lagerhaltung, da er die gleichen Drücker nicht oder nicht einfach mit verschiedenen Rosetten oder Schildern kombinieren kann.

There are various options for the axial fastening of lever handles. A common solution is to axially connect the inside and outside handles with their square pin. Many different lever handle square pin connections have been developed for this purpose. A second, also widespread, solution is to connect the handles in a radially rotatable but axially fixed manner to their plates or rosettes, which in turn are screwed onto the door. Widespread versions are those in which the pushers are connected to their plates or rosettes by snap rings (DE-Gbm 76 13 330) or by riveting in the factory. This has several disadvantages:

• The parts that are already connected to each other are more difficult to pack and ship than separate handles and handle bearings. The dealer also has a larger warehouse attitude, since he cannot or cannot simply combine the same pushers with different rosettes or signs.

To avoid these shortcomings, connections have already been developed that are only added shortly before the fitting is installed. E.g. the pusher can be locked in the manner of a bayonet catch with the associated plates or rosettes.

These connections must also be made before the signs or rosettes are screwed onto the door. However, this sequence is a hindrance if the signs and rosettes are to be screwed on invisibly. Because rosettes and signs for invisible screwing are usually formed in two parts from the lower part and top cap. During assembly, the lower part is first screwed on and then the cover cap is pressed on. However, if the handle is already firmly connected to the lower part when the lower part is screwed on, the cap with its handle bore must be threaded onto the end of the handle and pushed over the entire handle. This is only possible with pushers of a certain shape.

Apart from that, the handle that is already connected to the lower part is a hindrance when tightening the fastening screws. In addition, it is often desirable in the course of the construction to assemble the signs or rosettes or their lower parts at an earlier point in time, but only use the handles later so that they are not damaged during further construction work.

To avoid the above-mentioned defects, fittings have already been developed in which the handles can be snapped into their plates or rosettes when the plates or rosettes are already screwed to the door ( _D E-OS 26 41 096). The pusher can already mounted signs or rosettes can be inserted into them, but it can only be removed afterwards by removing the sign beforehand or, for example, pulling out a clamp using pliers-like tools. But the latter is in turn corner cap can only be removed at _D so that this solution is also suitable only for door handle forms in which the cover cap over the handle is removable and re-attachable. The bracket is also a loose part that can easily be lost. Before re-assembly, the clip must be reinserted, which is an additional operation that also requires pliers or skillful manipulation by hand.

, There is also a door handle arrangement known (D _E - _PS 10 29 702), in which within the door handle neck and possibly the square pin a radially resilient pin a rotatable but axially fixed connection with the rosette by radial engagement in a provided in the rosette Manufactures inner ring groove. The disadvantage here is that the resilient bolt only connects to the rosette along a small fraction of the pusher circumference. The handle can therefore tilt slightly unless it is prevented from doing so by a radial bearing of the appropriate length. Furthermore, the resilient pin is only in linear contact with the groove inner surfaces of the rosette. This results in high susceptibility to wear. Finally, the whole arrangement is only _R or signs with a very long front guide osetten possible as it is undesirable in modern fittings for technical reasons. Because only the guide collar of the rosettes, which is extended far outwards, gives the possibility of arranging the resilient bolt far enough outside that it no longer affects the square pin of the pusher or penetrates and weakens it far outside at a point where the pin does not exert any major stress is more exposed.

The object of the invention is to provide a Türdrückeranord- _now g to provide the initially kind mentioned, in which without the risk of losing the Kraftangriffs- and -übertragungsglieder at axially flat configuration of the bearing part on the one hand a problem-free mounting of the door handle by attaching the support member to the door leaf and applying the _D corner cap and on the other hand easy release of the door handle without first unscrewing of the bearing part and without complete removal of the cover cap is possible, where-0ei should be sufficient as a tool, a simple pin, a screwdriver and / or the finger tip or fingernail.

To achieve this object, the invention provides that the bolt or bolts and the force application and transmission members also form part of the bearing part in the unlocked position. Advantageously, it is further provided that the force application member through a small opening in the edge of the top cap by means of a pin or screwdriver or preferably by an internal stop of the top cap rotatably mounted on the bearing part or particularly preferably by one-sided lifting of the correspondingly elastically designed top cap from the bearing part formed gap can be acted upon by means of a pin, screwdriver and / or by hand in the unlocking direction.

The fact that the force application and transmission elements are arranged so that they cannot be lost on the bearing part makes the packaging and shipping of the door handle arrangement according to the invention considerably easier. At the assembly point there is no danger that these parts that are important for the function of the lever handle arrangement will be lost. The features of claim 15 ensure that the entire locking mechanism is designed so flat that it is easy can be accommodated in a bearing part formed axially with a normal thickness. It is particularly important to arrange the bolts on the one hand and the force application element and possibly also the force transmission elements in only two planes, which can be relatively thin, so that there is still enough space for the full material ensuring the stability of the bearing part, in particular the lever handle bearing surfaces and also for other advantageous internals. remains in the bearing part. The two levels are preferably close to each other in the front or rear area of the bearing part, so that a relatively deep storage area remains for accommodating other elements, for example play compensation devices, etc.

It is of particular importance that the force application element can be actuated practically with the cover cap attached or only slightly raised on one side slightly by 2 to 3 mm, so that when the force application element is acted on appropriately, the door handle can first be released and removed from the bearing part, after which it can be removed the top cap is completely removed and the bearing part can be unscrewed if necessary. The arrangement of the handle or the force application element near the rear surface is particularly important here.

Conversely, during assembly, the bearing part can first be screwed onto the door leaf, whereupon the cover cap is snapped on and only then the door handle is inserted into the door handle bore and axially fixed by inserting the latch into the circumferential groove. The insertion of the bolt into the circumferential groove, either by pressing the _K raftangriffsgliedes or also be carried out, however, that the bars are radially resiliently biased to the circumferential groove to and the door handle is provided at its free end face with a bevel, which in the described manner is able to resiliently push the latches radially radially so that they can finally snap radially into the circumferential groove when the door handle is inserted far enough into the door handle bore. The latter embodiment is preferred, since in this way it is not necessary to actuate the force application element when the door handle is inserted into the bearing part. Rather, this is moved into the locking position before the cover cap is applied.

The design according to claim 1 further ensures that the top cap is inevitably placed on the bearing part in a very specific angular position, so that the small opening is located at the point behind which the force application member can then be reached. In this alternative of the solution according to the invention, the arrangement of the small opening that is practically invisible from the outside is particularly advantageous in accordance with the last part of claim 1.

It is particularly preferred if the cover cap is detachably snapped onto the bearing part by means of latching surfaces.

The _D corner cap can in this way where appropriate with the exception of the above-mentioned small hole, and the door handle through-hole virtually without any other further openings are formed, which allows complete coverage of the bearing part and the force application and transmission members and the bolt to the outside. _S o is not visible from the outside of the actuating mechanism, nor can it be soiled by exposed to the outside or damaged.

When forming of the locking surfaces within the meaning of the present invention is to be noted that the locking faces inclined in such a way and are formed long that at one side lifted to form a sufficient to carry out a pin, screwdriver and / or fingernail gap _D, the top cap is not corner cap from the bearing part jumps off and preferably remains independently in the partially raised position until it is completely snapped or completely lifted off after the door handle has been fitted or removed.

In other words, the latching surfaces should not be designed so that the entire top cap jumps off the bearing part completely when the top cap is lifted slightly on one side. The design of the locking surfaces should therefore be such that the dead center, clearly jumping off beyond the top cap, is only reached when the top cap has been raised on one side to such an extent that the force application element can be reached through the gap formed.

The invention is particularly preferably applied to lever handles in which the handle neck has at its free end a pivot with a reduced diameter, which is separated from the part of the handle neck projecting outwards via a ring step. In this case, the cover cap lies axially against the ring step and cannot snap away from the bearing part when the cover cap is lifted on one side anyway.

Especially with door handles of this type, the invention can be used with particular preference because here the cover cap cannot be lifted off the bearing part at all before assembly or disassembly of the door handle, unless the door handle through hole has a larger diameter than the protruding part of the door handle neck. According to the invention, however, for the first time an embodiment is made possible in which the door handle neck can protrude radially with its projecting part radially beyond the door handle through hole of the top cap, without the operation of the force application and transmission elements lying within the top cap being impaired.

A particularly preferred embodiment is characterized in that the latching surfaces are inclined and long in such a way that the force application member can be acted upon through the gap when the cover cap is lifted and disengaged at about 180 ° from the point where the gap formed is furthest .

An essential feature of the invention is that the _K raft attack member can be actuated by an impact force with a radially inward and / or circumferential component. Furthermore, it is alternatively advantageously provided according to the invention that the force application element can be actuated by a torque about an axis lying between the radial and the circumferential direction.

According to the invention, the bolts can only be released from the circumferential groove of the door handle by a radially outward movement. An essential idea of the invention is that this radially outward movement of the bolt is triggered by an impact force or a rotary movement in the aforementioned sense.

Due to the design according to claim 4, a slight one-sided lifting movement of the top cap of, for example, 0.5 to 3 mm is sufficient to get to the force application member.

While the force application element expediently extends approximately to the edge of the bearing part immediately behind the edge of the top cap, it can also be provided that the force application element can be acted upon from the outside by a lateral, preferably essentially radial and straight channel.

However, it is preferred if the force application member is designed as a lever that extends almost to the edge of the top cap.

The lever is expediently movable in the circumferential direction.

An embodiment which can be accommodated in a particularly space-saving manner within a flat bearing part is characterized by claim 5.

The embodiment according to claim 6 ensures a particularly stable mounting of the radially displaceable bolts, and the assembly is also facilitated by the two-part design of the bearing part.

As already mentioned above, the bolts can be brought into engagement with the circumferential groove by spring force. In particular, it should be provided that the end face of the lever handle neck, but possibly also the latch or latches have a chamfer, so that the latch or latches are pushed radially outwards by the chamfer when the handle neck is inserted axially into the door handle bore, in order then to move automatically snap into the circumferential groove.

A particularly simple and economically feasible embodiment is characterized in that only one latch is provided on the periphery, which is a _K raftangriffsglied forming lateral oblique surface by a lateral force out of the peripheral groove can be lifted. It is particularly provided that the inclined surface at the end of the channel is arranged at 45 ° to the direction of movement of the bolt and the channel is perpendicular to the direction of movement.

An actuatable with particularly little effort development of this embodiment is characterized in that the _K raftangriffsglied a substantially radially extending screw having a preferably corner cap of the latch of the _D extending away in a corresponding threaded bore, said force transmitting member forming approach is arranged.

The embodiment according to claim ₈ is particularly theft-proof because it can only be operated with a correspondingly long screwdriver.

A structurally particularly compact arrangement is characterized in that the screw is surrounded by a helical spring which acts radially on the shoulder.

In order to achieve a particularly effective axial fixing of the door handle in the bearing part, the circumferential groove should have a rectangular cross-section, into which the edges of the latches, which are correspondingly provided with a rectangular cross-section, engage.

For a particularly good axial fixation, a plurality of bolts are expediently provided on the circumference, which are acted upon simultaneously by a single force application element via a transmission forming the force transmission element.

A first practical embodiment with two diametrically. bars arranged opposite one another are defined by claim 9.

An even better circumferential support of the door handle to improve the axial holding force is achieved by the embodiments according to claims 9 and 10.

The operation of all three, or four bolt by means of the actuatable through the radial lever cam ring one hand ensures a smooth transmission of the power supply _B etäti- other hand, permits a compact housing the Kraftangriffs- and transmission links within the bearing member.

A particularly simple conversion of the impact force applied from the outside into a tensile force acting on the slide is guaranteed by the features of claim 11.

All of the aforementioned exemplary embodiments of the invention are particularly suitable when the bearing part is a circular rosette.

However, the invention can also be used without difficulty in the case of bearing parts designed as an elongated door plate.

An advantageous embodiment of this type is characterized in accordance with the invention in that the latches around the door handle bore are secant rods which are fastened radially from the locking position in the circumferential groove essentially radially to the unlocking position on the bearing part.

Can in this case the rods are preferably resiliently deflectable to allow in connection with the chamfer on the end face of the _D Rücker neck insertion of the handle neck in the _T ür- _d Rücker drilling even if located in Verriegleungsstellung rods take place, which then to snap into the circumferential groove resiliently be pushed apart.

According to the invention, three or preferably four rods should preferably be arranged uniformly distributed over the circumference for a perfect axial mounting.

A particularly preferred movement and actuation mechanism for the resilient locking rods results from the definition of claim 13.

Finally, another idea of the invention is to press the latches resiliently and appropriately radially into the circumferential groove of the door handle in such a way that any radial play of the handle neck or the pivot pin arranged thereon is compensated for within the door handle bore. In this way, related manufacturing tolerances can also be easily compensated for in a simple manner.

According to the invention, the bolts and the force application and transmission elements should also form part of the bearing part in the unlocking position, ie that they form part of the bearing before joining and after unlocking the handle, and that the force application element also on the door mounted bearing part with a removed corner cap _D convenient means of a pin, screwdriver and / or by hand in the unlocking direction is acted upon.

A particularly preferred embodiment of the invention is characterized by claims 16 to 18. Due to the designs defined there, a particularly secure hold of the lever handle is guaranteed, although problem-free assembly and disassembly is nevertheless possible.

While the embodiment according to claim 17 is preferred, if there is not enough space, the slide can also be arranged between the pivot axis and the pusher opening, as a result of which the entire arrangement then has a greater radial extension in only one direction.

The embodiment according to claim 17 also has the advantage that such a slide can be used with a very flat tool, e.g. has the blade of a very small screwdriver actuated, which is pushed under the edge of the top cap or that a tool is inserted through the radial hole, by means of which the expansion slide is moved in the radial direction towards the handle, which causes the two bolts to spread.

Alternatively, it is also possible to design the arrangement without a separate spreader so that the tool for releasing the lock acts directly on inclined surfaces of the latches, which e.g. be formed by beveled transom sections.

Due to the design according to claim 18, it is ensured that the latches engaging on all sides in the circumferential groove of the lever handle pivot pin bear with their front surface on the rear surface of the steel cover plate. As a result, they form a steel collar that covers the presser bearing, as it does for Fire protection fittings is prescribed. This embodiment also ensures a stable single-point suspension sufficient for a fire emergency, since the bolts are caught in the groove of the handle.

If the bolts are held in the circumferential groove of the pivot of the door handle by radially acting spring forces, according to a further inventive idea it should be avoided that with simultaneous exertion of an axial tensile force and a pivoting moment on the door handle by means of friction, such strong forces are exerted in the direction of displacement of the bolts, that these can be pressed out of their locking position in the circumferential groove.

The occurrence of such unlocking forces can e.g. can be prevented by limiting the circumferential extent of the bolts in the circumferential groove, in that the tangential directions of the circumferential edges engaging with the circumferential groove deviate as far as possible from the direction of displacement of the bolts. Furthermore, the flanks of the circumferential groove and the side surfaces of the bolts should be as perpendicular as possible to the lever handle axis. Rounded cross-sections of the circumferential groove and the locking surfaces engaging in it should be avoided. In addition, the undesired axial pulling out of the lever handle against the holding forces of the bolts can be effectively countered by arranging more than one bolt, preferably two, three or four bolts, distributed over the circumference. In particular, a tangential, straight extension of the edges of the latches engaging in the circumferential groove should be avoided. The peripheral edges should rather adapt to the circular shape of the peripheral groove.

Another preferred embodiment to avoid unlocking at the wrong time provides that pivot locking means are arranged on the bolts and / or the elements surrounding them, which, when the lever handle is pulled, at least causes the bolt to move out of the circumferential groove of the pivot compared to the normal state when the lever lever is not loaded axially complicate. The inventive idea of this embodiment is therefore to be seen in the fact that when the lever handle is pulled axially, the spring forces holding the latches in their locking position in the circumferential groove of the pivot of the door handle are increased by clamping or frictional forces and stop forces when the door handle is pulled axially outwards . The design should preferably be such that the forces holding the bolts in their locking position increase either suddenly or steadily with the axial pulling force on the door handle.

Conversely, it is expedient if the clamping forces on the bolts are reduced in the event of axial pressure against the door handle, so that the unlocking of the bolts can be facilitated by means of the inventive means by axial pressure against the door handle.

An advantageous practical embodiment is characterized in that the latches pull axially by a predetermined small amount of e.g. a few tenths of a millimeter relative to an element surrounding the bolt are elastically displaceable and that the swiveling means become effective due to this slight displacement. In this embodiment, the bolts are also perpendicular to their intended direction of movement, namely slightly movable in the direction of the lever handle axis, which can be used to produce a clamping or friction or stop intervention, the measures according to claim 19 being expedient.

According to the invention, the unintentional loosening of the bolts can be achieved by small projections arranged on the back of the cover plate, to which the outer bolt edges run when they are pivoted outwards by the small amount when the rotating handle is subjected to tensile stress. The tensile load pulls the latches firmly against the cover plate, so that the small projections form an effective hurdle.

The depressions in the cover plate only need to be approx. 0.2 mm deep. If the bolts are pulled into this recess when the handle is subjected to a tensile load, an effective stop action is already established.

When the handle is joined, however, the latches are bent somewhat elastically by the handle in the direction of the door and thus pressed out of the recess; they can now be pivoted outwards in the ways according to the invention and thus brought out of engagement with the pivot of the lever handle neck.

The handle neck is chamfered at its free end so that its front diameter is smaller than the approximately circular opening within the mutually engaging bolt. The front transom edges are preferably also slightly chamfered in the area of the opening, which e.g. can already be achieved by appropriate selection of the punching direction in their manufacture.

If the handle is used, the bevels of the front chamfer force the bolts apart until they snap into the circumferential groove of the pivot of the handle handle neck.

In the vicinity of their parting line, the bars can - due to the pivoting kinematics - the moving against them _D rückerfase less easily dodge radially as in the _R iegelmittel. The pusher joining becomes consequently '. This is facilitated by the fact that the opening enclosed by the bars is somewhat enlarged in the region of the parting line - somewhat different from the ideal circular shape.

This also makes it easier to remove the handle during disassembly, as the outward-pivoting bolts cover the smallest radial path near the joints and release the handle last here.

• Es liegt ein geschlossener, umlaufender Eingriff der Riegel in der Umfangsnut des Drehzapfens des Türdrückerhalses vor. Dies ist aus Stabilitäts- und Verschleißgründen vorteilhaft und ergibt gleichzeitig einen überdeckenden stählernen Bund im Sinne der.deutschen DIN-Vorschrift 18082. Trotz dieser vorteilhaften und stabilen Verbindung sind keine komplizierten Kraftübertragungsglieder erforderlich, wie das z.B. bei der Ausführungsform mit vier radial verschiebbaren Riegeln erforderlich ist.

The advantages of the embodiment according to claims 16 to 19 are as follows:

• There is a closed, circumferential engagement of the bolts in the circumferential groove of the pivot of the lever handle neck. This is advantageous for reasons of stability and wear and at the same time results in an overlapping steel collar in the sense of the German DIN regulation 18082. Despite this advantageous and stable connection, no complicated power transmission members are required, as is required, for example, in the embodiment with four radially displaceable bolts .

Despite the stable mounting of the door handle, only a small amount of axial space is required, which is limited to the bolt thickness in the critical storage area, since a cam ring or the like. not applicable.

Also, the radial space requirement is small, because the construction has adialerstreckung only two or even only one direction a larger _R. The invention can therefore also be used with narrow long-round rosettes or signs for frame doors and even with a narrow sign that stops right above the pusher.

,,, Even when the plastic base body and other plastic parts melt, the handle remains axially fixed in both directions to the steel cover plate, in the simplest way thanks to the riveted pivot axis, which fulfills a double function.

There is a high axial load capacity, while on the other hand the joining can be carried out very easily when the handle is inserted axially. The handle can also be easily released. After removing the lever handle, the bearing part is ready for the next joining process without manual reset of the mechanics if the same or a different lever handle is used axially.

The design according to claim 20 counteracts a violent release of the lever handle with simultaneous pulling and pivoting.

1 and 2, a bearing part of a door handle arrangement according to the invention, designed as a rosette 13, consists of an annular bearing part base body 13 'made of plastic, which is covered on the outside and also on the circumference by a thin metal cover plate 13 ". The rosette is centrally located 2, the pivot pin 21 provided at the end of the handle neck 20 of the door handle 19 is plugged in. The dimensioning of the door handle bore 23 and the pivot pin 21 _' is such that in this way a pivot bearing _u ng of the handle neck is generates 20. the pivot pin 21 passes through in the axial direction virtually the entire thickness dimension of the bearing part of the base body 13 '. rotary performed the pivot pin is only in the bearing part base body 13''has a slightly larger and not in the metallic cover plate 13 ", of which the _T ürdrückerbohrung 23 corresponding bore 23 Has diameter. The reason for this assumption is the _M ASA avoiding scratches in the surface of the pivot pin 21 because the door handle preferably as well as the bearing part base body 13 'is made of plastic 19.

The rosette 13 is provided with two diametrically opposed mounting holes 36, of which _F ig according. 2 extends a hollow fitting pin 35 which is inserted into a corresponding fitting hole in the door panel. The back 60 of the rosette 13 is in the assembled state. on the surface of the door leaf, not shown.

At a circumferential point of the rosette 13, a radially directed, rectangular, shallow depression 28 is provided in the front surface of the bearing part base body 13 ', in which a latch 11 designed as a flat plate is arranged to be radially displaceable.

From the front, the flat bolt 11 is guided through the metallic cover plate 13 ″ of the rosette 13.

The bolt 11 has three straight sides which are at right angles to one another and a concavely circular edge 27 which faces the pivot 21 and which engages radially in a complementarily shaped circumferential groove 22 in the pivot of the lever handle neck 20.

The curvature of the edge 27 corresponds to the curvature at the base of the circumferential groove 22. The edge 27 and the circumferential groove 22 are arranged concentrically with the lever handle axis 26.

Radially outside the bolt 11, a spring receiving space 53 is provided in the bearing part base body 13 ', which is also covered by the cover plate 13 ". Inside the spring receiving space 53 there is a U-shaped spring 37 which is located radially on the outside of the bearing part base body 13' and radially supported on the inside of the bolt 11, whereby this is biased into the locking position shown in FIGS. 1 and 2.

2, a projection 18 is bent from the bolt 11 to a receiving space 61 via a bend, which has a 45 ° inclined surface 12 which extends through a channel 33 extending straight from the side of the rosette 13 by means of a pin or screwdriver is achievable.

The receiving space 61 is sufficiently large in the radial direction to allow the bolt 11 to radially spring out so far that it comes out of engagement with the circumferential groove 22.

The rosette 13 is completely covered by a cover cap 16, the edge 15 of which laterally surrounds the rosette 13 and extends so far that its rear surface 62 is flush with the rear surface 60 of the rosette 13. In this way, the top cap 16 completely covers the rosette 13 including all the parts arranged on it.

It is of particular importance that the cover cap ür- a _T pusher through-hole 24 has having a significantly smaller diameter than the outwardly projecting part of the door handle neck 20th Between the inner wall 01930

a radial play 63 is left of the _{door handle through} g _on g _{slots 24} and the circumference of the _pivot pin 21, which corresponds to the radial play between the pivot pin 21 and the cover plate 13 ″.

That of the _D between the pivot 21 and the protruding part Rücker neck 20 present, extending in a radial plane annular step 25 thus lies axially on the surface of the cover cap 16 or is in such a small axial distance, that the annular gap 63 is not visible from the outside ar is.

Ig by _F. 1, the edge 15 of the top cap 16 at the location of the straight lateral channel 33 can have a small opening 14 corresponding in cross section to the channel cross section, through which a pin can be guided to the inclined surface 12. By exerting an impact force on this pin from the outside, a radial movement of the bolt 11 then takes place outward via the inclined surface 12, which acts as an inclined plane, with the spring 37 being compressed.

By means of a radial projection 29 on the top cap 16 and a complementary recess 30 in the rosette 13, such an alignment of the top cap 16 and the rosette 13 can be ensured that the small opening 14 is aligned with the channel 33.

However, it is preferred that no opening is provided in the edge 15 of the top cap 16, but that due to a suitable design of the latching surfaces 38 on the inner circumference of the edge 15 or on the outer circumference of the rosette 13, the top cap 16 in the region of the channel 33 on one side as far from the Rosette 13 can be lifted off, that the channel 33 is exposed and, analogously to the way through the small opening 14, a pin or a screwdriver can be inserted into the channel 33 to actuate the inclined surface 12.

The cover cap 16 must be so thin and elastic that it can be lifted on one side while the cover cap 16 is deformed elastically. The remaining part of the top cap 16 is held flat on the rosette 13 by the ring step 25 during this process.

• Zunächst wird in üblicher Weise mittels der Befestigungsbohrungen 36 und nicht dargestellter Bolzen die Rosette 13 passend an einem Türblatt festgeschraubt. Hierbei dringen die Paßzapfen 35 in eine entsprechende Paßbohrung des Türblattes ein.

The assembly of the lever handle arrangement described proceeds as follows:

• First, the rosette 13 is screwed to a door leaf in a conventional manner by means of the fastening holes 36 and bolts, not shown. Here, the fitting pins 35 penetrate into a corresponding fitting hole in the door leaf.

The cover cap 16 is then snapped onto the rosette 13 by means of the latching surfaces 38.

There is then the door handle axially ür- by the door handle through hole 24 of the cover cap 16 in the _handle-T drilling introduced 23rd

A chamfer 31 provided according to the invention at the free end of the pivot pin 21 pushes the bolt 11 radially outward against the force of the spring 37, so that the pivot pin 21 can finally reach the position shown in FIG. 2, in which the bolt 11 under the effect of the Spring 37 snaps into the circumferential groove 22.

The door handle 19 is now rotatably but axially fixed to the rosette 13.

The handle neck 20 also the usual, not shown square hole is located, and Rücker neck upon insertion of the _D 20 in the door handle bore 23 is introduced to the square pin, not shown in the respective square hole at the same time.

According to the invention, the door handle da 0793081 can be disassembled so that a pin is inserted into the channel 33 either through the small opening 14 or through the gap which arises when the Dek cap 16 _" is lifted on one side, as a result of which the bolt 11 is displaced radially outward and the edge 27 disengages from the circumferential groove 22. The handle neck 20 can now be pulled off axially, the cover cap 16 can then be completely removed from the rose 13 and the rose can then be unscrewed from the door leaf unhindered.

By a sufficient radial pressure of the spring 37 also a certain slight bearing play of the pivot pin 21 within the door handle bore 23 erfindun ^g can be compensated in accordance with s-simple manner.

Although the force application and transmission members 12, 18 and the bolt 11 and the parts cooperating with it are arranged within the rosette 13, they practically do not increase the axial depth of the rosette 13 because of the design according to the invention. The entire actuating mechanism is covered to the outside by the cover cap 16 and is thus completely protected against being viewed from the outside and also against contamination or damage. Nevertheless, due to the measures according to the invention, actuation can take place without problems either through the small opening 14 or through the gap formed when the cover cap 16 is partially lifted on one side.

Another alternative for a radial actuation of the bolt 11 is that a dashed radial threaded bore 70 is provided in the bent extension 18 and that a corresponding thread is provided by a radially aligned rectilinear radial channel 71 with the cover cap 16 partially raised in this area having screw inserted and screwed into the threaded bore 70. The bolt 11 can then also be temporarily lifted radially out of the locking position by radially tightening the screw in question.

In the following exemplary embodiments, the same reference numerals designate corresponding components as in FIGS. 1 and 2. The function is also corresponding, unless stated otherwise in connection with the individual exemplary embodiment.

3 and 4, the radially displaceable bolt 11 is again mounted in a radial recess 28. It has a shoulder 18 projecting radially vertically in the direction of the rear surface 60, in which a continuous radial threaded bore 34 is provided.

A radial screw 12, which represents the force application element, is screwed into the threaded bore and engages with a. axially projecting flange 64 of the rosette 13 cooperates. The screw 12 is aligned radially with a radial channel 33 provided on the edge of the rosette 13. The radial channel 33 and the radial screw 12 lie on a common radial axis 32.

The screw 12 is concentrically surrounded by a helical compression spring 37 '; which is supported on the one hand on the axial extension 18 and on the other hand on the edge of the rosette 13 around the area of the channel 33. For the spring and the radial screw 12 contained therein, a receiving space 65 adjoining the radial channel 33 is provided in the rosette 13.

In FIG. 4, the one-sided bending of the top cap 16 is shown somewhat exaggerated on the left in dashed lines, as a result of which the channel 33 is exposed and a screwdriver for actuating the radial screw 12 can be inserted there. By screwing in the screw 12, the edge 27 is lifted out of the circumferential groove 22 of the pivot pin 21, while on the other hand, by unscrewing the screw 12, the bolt 11 can be brought back into the radially inner locking position shown in FIGS. 3, 4 by the spring 37 '. The assembly and disassembly of the door handle 19 is otherwise as described above with reference to FIGS. 1 and 2.

It is preferred if the radial channel 33 and the receiving _{space 65 are} even closer to the rear surface 60 of the rosette 13 can be arranged, as indicated by dashed lines in Fig. 4 at 33 'and 65'. In this way, the need _D corner cap 16 on one side only significantly to be far less lifted from the rosette 13, as the strength in _F. 4 is indicated by dashed lines at the top left.

In all of the exemplary embodiments, the force application member 12 should be provided as close as possible to the rear surface 60 of the rosette or of the bearing part 13, in order to make it possible to lift the rosette 13 as little as possible on one side.

The embodiment according to FIGS. 5 and 6 works with two diametrically opposed bolts 11, whose edges engaging with the circumferential groove 22 of the pivot 21 of the pusher neck 20 extend over an angle of approximately 90 °, similarly to the previous exemplary embodiments Bolts are, however, designed to be substantially wider than in the previous exemplary embodiments, so that they extend largely around the door handle bore 23, where they are still at a slight distance A from one another. In this area, the bolts have axially angled lugs 39 in the direction of the rear surface 60, between which an oval cam 40 is arranged, the axis 32 of which extends perpendicular to the direction of movement of the bolts 11. The cam 40 is connected in a rotationally fixed and axially aligned manner to a force application member designed as a screw head 12, which can be acted upon by a screwdriver through a radial opening 41 in the rosette 13 aligned with it.

The two slides 11 are ig in the front view according to _F. 5 biased on both sides by helical compression springs 37 'in the direction of their locking position.

The lugs 39 and the cam 40 form a gear 18 ', which represents the force transmission member between the screw head 12 and the bolts 11.

By lifting the top cap 16 laterally in the region of the radial opening 41, the screw head 12 can be exposed and rotated by 90 ° by means of a screwdriver, as a result of which the bolts 11 disengage from the circumferential groove 22. Otherwise, the function is the same as the previous exemplary embodiments.

Here, too, the mutually cooperating latching surfaces 38 should be designed such that they promote the limited one-sided lifting of the top cap to expose the radial opening 41, the design advantageously being such that, after the radial opening 41 has been exposed, the raised half of the top cap 16 is preferably remains in this position, for which purpose the latching surfaces 38 are said to have slightly exceeded the dead center of the latching-release movement.

The embodiments according to FIGS. 7 to 13 have four uniformly circumferentially distributed flat bar 11 of the door handle neck 20 are shown in FIGS. 8, 11 and 13 all around with the circumferential groove 22 at the _D rehzapfen'21 engaged.

The bolts 11 have pins 42 which pass axially through them and which, according to FIGS. 7, 8, are each acted upon radially inwardly by a helical compression spring 37 '. The helical compression springs 37 ′ are supported radially on the outside at the edge of the bearing part base body 13 ′.

The springs 37 'are provided on the side of the bolt 11 facing away from the lever handle 19 in the receiving spaces 65.

On the side of the latch facing the door handle 19, the pins 42 work together with a cam ring 18 ″ which surrounds the door handle bore 23 and preferably has approximately the same inner diameter as the door handle hole 23. At its outer side of the cam ring 18 "is ig according _F. 7 is partially circular and partially secant, so that in the region of the forwardly projecting portions of the pins present 42 secant-shaped control surfaces 44, which cooperate with the radially inner surface line of the axial pins 42 .

Radially from the cam ring 18 "branches off a radial lever 12 which extends up to a sector-shaped cutout 66 of the rosette 13 and there carries a circumferential spring abutment 67 and radially further outwards a handle 12 'which leads to the rear surface 60 of the rosette 13 is angled.

In a circumferential recess 68 extending behind the radial lever 12 there is arranged a circumferential spring 43 which is curved in accordance with the curvature of the rosette and which is supported with its end facing away from the abutment 67 on an abutment 69 connected to the rosette 13 in the circumferential direction.

The circumferential spring 43 is under such tension that it biases the cam ring 18 "into the position shown in the drawing, where the bolts 11 are under the action of the helical compression springs 37 'in engagement with the circumferential groove 22 of the pivot 21 of the pusher neck 20.

If the radial lever 12 is now rotated clockwise as shown in FIG. 7, the pins 42 run obliquely outwards on the control surfaces ₄ 4, the edges 27 of the latches 11 disengaging from the circumferential groove 22.

After releasing the radial lever 12, the circumferential spring 43 automatically pushes the cam ring 18 "back into the locking position shown in FIGS. 7, 8, whereupon the springs 37 'move the latches 11 back into the locking position.

• Entweder sind an der Deckkappe 16 innen und von außen unsichtbare,in Fig. 7 gestrichelt angedeutete und in Fig. 9 im einzelnen dargestellte Radialanschläge 17 vorgesehen, die bei einer Verdrehung der in diesem Fall drehbar angebrachten Deckkappe 16 im Uhrzeigersinn in Fig. 7 den Radialhebel 12 in der vorstehend beschriebenen Weise in Uhrzeigersinn verdrehen.

The radial lever 12 can be actuated in two ways:

• Either radial stops 17 are provided on the inside and outside of the top cap 16, indicated by dashed lines in FIG. 7 and shown in detail in FIG. 9, which, when the top cap 16 is rotatably mounted in this case in a clockwise direction in FIG. 7, have the radial lever Turn 12 clockwise as described above.

The other alternative is that the stops 17 are not provided, but that the cover cap 16 in the area of the handle 12 'can be raised on one side to such an extent that the handle 12' can be gripped and actuated by means of a pen, screwdriver or fingernail can.

The embodiment according to FIGS. 10, 11 largely corresponds to that according to FIGS. 7 to 9 and can also be actuated by means of the two alternatives described there. However, it lacks the circumferential spring 43; instead, the radial lever 12 in its two end positions, which correspond to the locking or unlocking position _{/ can} be snapped into an assigned locking recess 47 of the rosette 13 by means of an axial locking cam 48 provided on it. This allows the two related positions to be fixed.

After unlocking, the bolts 11 thus remain in their unlocked position until the radial lever 12 according to FIG. 10 by means of a screwdriver, a pin or by hand or else by means of the twisted cover cap by means of the stops 17 in the counterclockwise direction into the one shown in FIG. 10 apparent 'locking position is rotated.

The embodiment according to FIGS. 12, 13 again works with the circumferential spring 43 of the embodiment according to FIGS. 7 to 9, but here the radial helical compression springs 37 'for the radially inward bias of the bolts 11 are omitted. Instead, oblique slots 45 cooperating with the axial pins 42 are provided in the cam ring 18 ″, on the longitudinal edges of which two control surfaces 44 are formed, one of which is effective when unlocking, the other when locking bolts 11 are on the side facing rear surface 60 the axial pins 42 according to FIGS. 12, 13 in radially extending guide recesses 46, which contribute to absorbing the circumferential forces occurring when the cam ring 18 "is rotated.

The embodiment according to FIGS. 12 and 13 can also be operated with the two alternative possibilities described with reference to FIGS. 7 to 9. Due to the circumferential spring 43, the cam ring 18 "is automatically returned to the locking position shown in FIGS. 12, 13 after the end of an actuation, the bolts 11 also automatically taking the position shown in FIG. 12. When pressing the trigger neck 20 accordingly Fig. 13 can give the latch 11 by rotating the cam ring 18 "and compression of the spring 43 radially outwards until they snap into the circumferential groove 22 by itself.

The embodiment described in FIGS. 14 and 15 operates with a diametrically displaceable slide 18 '''which has such an opening in its central areas, that the pivot pin 21 of the _T ürdrückerhalses 20 at all positions of the slide 18''' unhindered the door handle bore 23 can occur.

From one side, the slide 18 '' 'is spring-loaded by a leaf spring 37 in the locking direction. The spring 37 is arranged in a spring receiving space 53.

The slider 18 '' 'carries a leg spring 50, the web 11' of which on the side of the spring 37 runs perpendicular to the direction of displacement of the slider 18 '' 'and parallel to the circumferential groove 22, in such a way that in the case of FIG. 14 , 15 visible locking position engages in the circumferential groove 11 '.

The two legs 11 ″, which are essentially angled in a triangular manner downwards, also spring into the circumferential groove 22 at angular positions offset by approximately 120 °. The free ends of the legs 11 ″ are guided in arcuate slots 72.

In the area of the transition from the web 11 ′ into the legs 11 ″, the leg spring 50 is guided around cams 51 fastened to the rosette 13.

The slide 18 '' 'has straight side surfaces 52, by means of which it is guided diametrically in a recess in the rosette 13.

At the end facing away from the spring 37, the slide 18 '''runs conically radially in the manner shown in FIG. 14 to the outside and there has an angled portion 12 serving as a force application member with a handle 12 'at the axially inner end, which extends approximately to the rear surface 60. Radially outside of the bend 12 is in alignment with it a radial opening 41 in the edge of the rosette 13, through which, with the cover cap 16 partially raised, an impact tool such as a pin or screwdriver for displacing the slide 18 '''in the direction of the arrow F 14 can be introduced.

During this shift, the spring 37 is compressed. The web 11 ′ also lifts out of the circumferential groove 22, like the legs 11 ″, which are spread outwards due to their sliding along the rosette-fixed cams 51, their ends sliding outwards in the arcuate slots 72.

After releasing the bend 12, the slide 18 ″ ″ again reaches the locking position shown in FIGS. 14, 15, in which the web 11 ′ or the legs 11 ″ are located in the circumferential groove 22.

_D a both the web 11 'and the legs 11 "can radially rebound, the pivot 21 of the pusher neck 2 _{0 can} also be inserted axially when the slide 18"''is in the locked position, the web 11' and the legs 11 "initially are pressed resiliently radially outwards until they snap into the peripheral groove 22 automatically.

While in the preceding embodiments the bearing part is formed by a escutcheon 13, which show _F ig. 16 to 20 show an exemplary embodiment in which two bearing parts arranged on opposite sides of a door leaf (not shown) are each designed as an elongated door plate 13a with a lock through opening 55.

The two door plates 13a arranged on opposite sides of the door leaf are fastened to one another and to the door leaf by bolts 58 and nuts 36 'inserted from opposite sides. 17 also shows the square pin 59, which is also to be regarded as present in all other embodiments.

In the area of the door handle insertion, each door plate 13a has a coaxial projection 56 which projects axially into a corresponding recess in the door leaf and which is covered by a sheet metal cover pot 57. In this way the _T is ür- pusher guided over a greater axial length.

As shown in Fig. 17 in the upper part of the door handle 19 in the locked into the door handle bore 23 position, it is in the lower part of the figure already on the _V ierkantstift in namely 59 slid on, but not yet reproduced 23 inserted condition in the door handle bore.

The Kraftangriffs- and -übertragungsglieder are pure according to _F. 17 to 19 are formed by four secant-like rods 11 '''which fit and engage radially from the outside in the circumferential groove of the pivot pin 21 of the lever handle neck 20. With one end of the rods extend into the region of the _T ürschildes 13a where they are pivotally mounted about parallel to the door handle axis 26 pivot axes 54th

At the other end, the rods 11 '' 'are slidably mounted in oblique slots 45 of a cam ring 18 ", which is of similar design and functions like the cam ring 18" according to FIGS. 12, 13.

_N ockenring 18 "extends radially a radial lever 12 to the lateral edge of the door plate 13a, but where the edge 15 of the top cap the radial lever 12 and provided on him angled to the rear face handle 12 covers 16 'to the outside. Two in the door plate 13a The provided locking recesses 47, in conjunction with the locking cam 48 of the radial lever 12, allow the cam ring 18 "to be locked in the locking and unlocking position.

In Fig. 18 the cam ring 18 "is in the locking position in which, according to Figs. 17 and 19, the rods 18 '' 'engage radially in the circumferential grooves 22 on the pivot pin 21, so that the door handle 19 is locked axially.

19 in the area of the handle 12 'resiliently and the radial lever 12 is rotated clockwise in Fig. 13, the oblique slots 45 move the rods 11''' radially outwards until they finally in the manner shown in Fig. 20 _e ntriegelungslage from the Türdrückerbohrugn 23 are radially exited. Now the door handle can be removed axially.

_D a is the rods 11 '''according to the invention preferably are resiliently deflectable, the door handle of the representation 17, according to the lower half of Fig. Axially even when in Verrie ^g e-lung position located rods 11''' are introduced by the chamfer 31 the rods 11 '''bend resiliently radially outwards when the pivot 21 is inserted, until they finally snap radially into the circumferential grooves 22 when the circumferential groove is axially aligned with them.

A perfect axial securing of the rods 11 '' 'in the circumferential groove 22 is ensured if both the rods 11' '' and the circumferential groove have a rectangular or square cross section.

In all exemplary embodiments, the same reference numbers designate corresponding components.

In the exemplary embodiment according to FIGS. 21 to 24, axially displaceable wedge segments 83 are provided around the door handle bore 23 of a rosette with a bearing part 13, which are arranged evenly distributed in the circumferential direction, each with a slight spacing. The radially inner surfaces 84 of the wedge segments 83 are designed as part-circular cylinders and are complementary to the cylindrical outer surface of the lever handle pivot pin 21.

The radially outer surfaces 85 of the wedge segments 83 are partially conical and cooperate with the radially inner partial cone surfaces 86 on the bearing part 13 such that the wedge segments 83 not only move axially but also radially due to the conical surfaces 85, 86. Axially arranged springs 87 exert such an axial force on the wedge segments 83 that they try to move in the direction of a reduction in diameter of the surfaces 84. The springs 87 are axially supported on a pot plate 88 of the liger part 13.

In this way it is achieved that the pivot pin 21 is held on all sides without play on the bearing part 13, which can be fastened to the door leaf by means of bolts 90 inserted through holes 89.

The lever handle neck 20 is held axially by two plate-shaped bolts 11 which are provided directly in front of the wedge segments 83 in a front recess 91 of the plastic base body 13 'of the bearing part 13. The two plate-like bolts 11 are rotatably supported on the steel cover plate 13 "of the bearing part 13 by means of a common pivot axis 73, with a leg spring 37" trying to pivot the two bolts 11 against one another. The axis 73 is located radially outside the door handle bore 23 and has a head 80, by means of which the leg spring 37 ″ is held securely in its position even if the plastic parts should melt away in the event of a fire.

In the area of the door handle bore 23, the bolts 11 have cutouts complementary to the circumferential groove 22 of the pivot pin 21 with circular edges 27 which, according to FIGS. 21 and 22, can engage with the circumferential groove 22, with the bolts 11 according to FIG. 22 92 touch on the side of the door handle bore 23 facing away from the axis 73.

In order to be able to disengage the bolts 11 and the circumferential groove 22, inclined counter surfaces 76 are provided on the end facing away from the axis of rotation 73, on which inclined surfaces 75 of a radially movable expansion slide 74 bear, which according to FIG. 21 has an actuated part bent toward the door leaf 93 has a tool which can engage radially when the top cap 16 is raised somewhat, in order to push the two bars 11 apart against the force of the leg spring 37 ″ by moving the expansion slide 74 in the direction of the arrow in FIG. 22.

As a result, the bolts 11 finally assume the position shown in FIG. 23, in which the edges 27 are out of engagement with the circumferential groove 22, so that the lever handle 19 can be removed or inserted axially.

After the actuating force has been removed from the slide 74, it moves back into its original position due to the action of the leg spring 37 ″ and the inclined surfaces 75, .76.

The pusher can be inserted without actuating the slide, because the chamfer 31 presses the bolts 11 apart until they snap into the circumferential groove 22 by themselves.

According to FIG. 24, an approximately rectangular depression 82 with a depth of only about 0.2 mm is provided in the rear surface of the cover plate 13 ″, the width of which is just so large that the side edges 81 acting as stops when the bolts 11 are in the engaged position ( 22) are aligned with the lateral outer edges of the latch 11. The area of the depression 82 is such that when the handle is pulled out axially in the direction of arrow f in FIG. 21, the latch 11, which is initially immediately behind the depression 82, is somewhat axially bent outwardly, thereby entering the recess 82nd now, the side edges of the latch 11 in _A nschlagverbindung with the side edges 81 of the recess 82nd

Due to this embodiment, a kind of self-locking of the latch 11 takes place during the axial pulling in the direction of arrow f according to FIG being held.

26 to 28 show a similar arrangement for a door plate, but with the expansion slide 74 being arranged on the same side of the door handle bore 23 as the latch-pivot axis 73, specifically between the axis 73 and the door handle bore 23 purpose the two laterally swiveling bolts 11 are provided with cutouts below the door handle bore 23, on which the inclined counter surfaces 76 are provided and within which the expansion slide 74 with the inclined surfaces 75.

In contrast to the previous exemplary embodiment, the expansion slide 74 of the embodiment according to FIGS. 25 to 28 has an axially projecting actuating part 93 'in the region of a collar 13' '' surrounding the pivot 21 of the door handle, which actuating part 93 'is located in a radial recess 77 on the circumference of the collar 13 '' 'is housed.

The cover cap 16, which serves as a particularly good guide 13 and the cover plate 16 covering the door plate, has a radial hole 78 in the area of the actuating part 93 ', as does the steel cover plate 13 covering the plastic cover 13 " ^l , through which the spreading slide 74 can be actuated by means of a pin-like tool, via the actuating part 93 ', which, during this actuation, can deflect into the correspondingly deep radial recess 77.

The collar 13 '' 'and the parts of the cover plate 13' 'and the cover cap 16 surrounding it form a so-called front guide 79 for the pivot 21 of the door handle 19. The collar 13' '' forms part of the bearing part 13.

25 to 28, a depression 82 with stop edges 81 is provided inside the cover plate 13 ". Because of the cover plate part 13" a (FIG. 25) surrounding the collar 13 '' 'there is also on the back of the collar 13 "" an intermediate cover plate part 13 "b is provided, in the rear surface of which the depression 82 is arranged.

Except for the slightly different actuation of the expansion slide 24, the function of the embodiment according to FIGS. 25 to 28 is analogous to that of the embodiment according to FIGS. 21 to 24.

All of the embodiments therefore work according to the same basic principle, in that the force application and transmission elements 12, 12 'or 18, 18', 18 '', 18 '' 'or 74.93.93' arranged captively on the bearing part 13, 13a can be actuated either through the cover cap itself, through a small opening in the cover cap or through the partially lifted off cover cap, the latches preferably being so resiliently radially outward that the latching of the door handle 19 without actuation of the force application and transmission members can be done.

It is particularly important that the edge 27 of the latch 11, which is in engagement with the circumferential groove 22, does not emerge from the circumferential groove 22 as tangentially as possible, but at least with a considerable radial component, which has the advantage that the latches are released automatically when pulling and Turning the lever handle is safely avoided.

All of the exemplary embodiments have the basic idea in common that, in order to release and / or join the lever handle, the bolt or bolts are moved or moved in their entirety and are not brought into or out of engagement with the circumferential groove or not only by deformation.

This arrangement combines high axial load capacity of the handle with smooth actuation of the latch for the intended release of the handle.

In all of the exemplary embodiments, the cover cap 16 can also be omitted if it is not required to cover the fastening screws or the like. The latches or the force application or transmission members are then actuated through an opening in the cover plate 13 "(or by partially slightly lifting the cover plate 13").
