Abstract

The fastening control comprises a collar in which either a drive nut for the force application of an operating handle (34) or on which the drive nut of the operating handle is rotatably supported. The drive nut has a recess (22) to accept the endpiece (23) of a shaft (24). The free end of the shaft serves as an engagement piece for a rotating coupling of the drive element of the fastening device. The shaft has a polygonal cross section. The end piece and the swing bearing head piece of the shaft have the same cross-sectional shape and size as the length of shaft between the peripherally narrower parts. The peripherally narrower parts to the end piece and swing bearing head piece are each defined by a steep pyramid surface, and by a flat conical surface to the shaft middle. <IMAGE>

Description

The invention relates to an actuating device for a Breech gear, especially on one double-leaf window, a double-leaf door or the like without mullion or on a window, door or Like. With at least one wing opening outwards. Here this actuator consists of a rosette, in which is either a driving nut for the power attack of a Operating lever or directly an operating lever is rotatably mounted with drive nut. Also points out Drive nut has a recess for positive locking an end piece of a shaft, the free end of which Rotary coupling driver for a drive element of the Lock gear serves.

Double-leaf windows and doors or the like without a mullion were made at least 40 years ago (see e.g. FITTING MANUAL Volume I; Windows and shutters, drawing sheet No. 1002 from 1951, drawing sheet No. 1003 from 1951 and drawing sheet No. 1301/1302 from 1952 ) and are built again today (see, for example, DE 34 38 126 C2 ) in such a way that an appealing, symmetrical overall view is created, at least from the inside, without significantly influencing the view width of the adjoining wing leg.

To ensure the symmetrical overall view of the Window or door in the area of the adjacent Wing leg is natural - like the ones mentioned Show documents clearly - necessary for the Operation of the locking gear necessary operating hand lever with its rosette also in the middle of the overall view of the two winged legs, especially on one to arrange so-called blow bar. This is on the Attached to and inside of the main wing The closed position of both wings is the face of the room Secondary wing ..

So despite the relatively narrow overall view of the adjacent wing height limbs the stability the same through the stepped profile Hardware groove is not permanently impaired, this is Fitting groove with a greater distance from the bottom of the Blow bar in a fold circumferential surface on the wing leg of the main wing, which corresponds to the plane of symmetry General view of the adjoining wing leg from Main and secondary wings are at least close.

The containing the step-shaped profiled fitting groove Folded circumferential surface can be on the wing leg of the Main wing either towards the secondary wing with a distance in front of the Plane of symmetry, or away from the secondary wing behind the Plane of symmetry. In any case, when installing a connecting rod lock in the fitting groove of the Main wing whose locking gear with the axis of rotation its drive element, especially a pinion, however in a position which is laterally offset Plane of symmetry and thus also to the one in the cover position extending shaft of the operating lever.

Even with windows and doors with at least one on the outside opening wing, it is often inevitable that the axis of rotation the drive element, in particular pinion, in Locking gear of the espagnolette lock with side Staggered to the shaft of the inside of the Wing leg mounted operating lever to lie is coming. In this case, the operating lever must be with its rosette on the inside of the opening-side wing leg that he in the outward opening movement of the wing on neighboring frame spar or wing height leg unhindered can be moved past.

To bridge the gap in the aforementioned cases unavoidable lateral misalignment between the Drive element of the locking gear and that on the Inside of the wing with the help of its bearing rosette mounted control lever is the use of so-called Intermediate gear known as for example by FR-A-2 239 894 or also DE-U1 91 03 676.

Apart from the fact that these intermediate gears because of their multi-part construction a high manufacturing and They require a special expense Inadequacy in the fact that they are only fixed for one Axial misalignment between the operating lever and the locking gear are built. Different relative positions of the hardware groove of the main wing to the plane of symmetry of the overall view or to the axis position of the operating lever also require correspondingly different intermediate gears. A not inconsiderable manufacturing and storage expenses the consequence.

The purpose of the invention is to eliminate them Shortcomings. It is therefore the task of a Actuating device of the type specified at the outset propose which is not only complicated to use and thus avoids costly intermediate gears, but also offers the possibility of being in a and the same version different axis offset positions between the drive member of the shutter gear of Espagnolette locks and the shaft of the operating lever easy to bridge.

daß einerseits das Endstück der Welle in der Ausnehmung der Antriebsnuß pendelnd gelagert ist,

und daß andererseits auch das freie Ende dieser Welle ein Pendellager-Kopfstück als Steck-Kupplungsglied für das Antriebselement des Verschlußgetriebes aufweist.

A generic actuating device which fulfills these requirements is basically characterized according to the invention in that

that, on the one hand, the end piece of the shaft is pivotally mounted in the recess of the drive nut,

and that, on the other hand, the free end of this shaft also has a self-aligning bearing head piece as a plug-in coupling element for the drive element of the locking mechanism.

The shaft of the Actuator leads to the formation of two torque transmitting diffraction joints between the Control lever and the drive element of the Lock gear, which the existing one Axial misalignment due to the inclined position of the Bridge the intermediate shaft without problems as long as certain diffraction angles (around 15 °) are not essential be crossed, be exceeded, be passed.

According to the invention, it could also be advantageous if the Shaft of the actuator in the area between the oscillating bearing in the drive nut and its the Drive element of the firing gear facing Pendulum bearing head piece is adjustable in length is to also different distances between the Installation level of the actuating device and the installation level to be able to bridge the locking mechanism without any problems.

At this point it should be mentioned that it is in connection with so-called double or box windows to the state of the Technology belongs (see, for example, DE-C 705 675) that Drive elements of the actuating gear both in the various wing built-in connecting rod fittings a multi - sectioned and adjustable in length to couple the length-adjustable PTO shaft. The Espagnolette fittings on both wings can be at the same time as that mounted on the inner wing Operating lever can be switched. So this is about two identical or similar actuation gearboxes different window or door sashes depending on the operator to couple with each other, but not to save one Intermediate gear.

It should also be mentioned here that there is already one Mounting rosette rotatably mounted operating lever there (see e.g. DE-U 74 24 932), whose for coupling with the Drive element of a locking gear serving shaft in a recess of the lever neck held pendulum is. However, this is only about one stiff interaction of the control lever with the Locking gear in the event of inaccuracies in work to prevent. This possibility could e.g. surrender if as a result of an inaccurate stop, a small axis offset the central axis of the drive element and the axis of rotation of the Operating lever occurs, which is of its size is 1 mm, but not more than 2 mm and is fixed with the Operating lever connected shaft to tension and would lead to stiffness. Any Findings that go to the bridging of a large axis misalignment (e.g. 10 millimeters to 15 millimeters) normally between the control lever and the locking gear additionally provided intermediate gear can be saved can, but this prior art also conveys one Not a professional.

According to the invention, the shaft has a polygonal cross section, in particular square cross-section, wherein both their end piece and their self-aligning head piece in the Connection to a circumferential constriction with the corresponding Square cross-section integrally formed on this and for free end is crowned.

Advantageously, the end piece and Self-aligning bearing head piece of the shaft - wherever it is Rotary coupling drivers form - the same cross-sectional shape and cross-sectional dimensions, such as those between the Circumferential constrictions. I.e. the Constrictions should be non-cutting or cutting, e.g. by pressing or milling, into one along its entire length the same cross-section shaft are molded.

In some cases it is also recommended that the the drive nut bearing rosette as one under the Rosette of a commercially available operating lever can be set Execute adapter piece, this adapter piece with Passages for the fastening screws and possibly also for plus coaxial locating pins of the operating hand lever bearing rosette is provided. In this way you can namely an actuating device according to the invention in Combination with many different designs Use commercially available control levers.

With the drive nut in the adapter piece, but also with the recess of the immediately in the neck of the Operating lever provided drive nut can be the end piece the shaft is axially displaceable and oscillating, but limited remaining inextricably linked. On the other hand should be the self-aligning bearing head piece formed at the free end of the shaft with the drive element of the locking mechanism only in a detachable, but non-rotatable and limited bendable connector.

In any case, it can be an advantage if after the Invention of the constriction of the circumference to the tail and Self-aligning bearing head piece each by a steep Pyramid surface and towards the center of the shaft through a flat surface Tapered area is limited and the flanks of the pyramid and of the conical surfaces with each other about a right angle lock in. The cone angle of the flat conical surface can advantageously between 145 ° and 150 °, for example at 148 ° lie, so that the angle of the steep pyramid between 30 ° and 35 °, e.g. at 32 °.

In order to be able to bridge different distances between the mounting level of the actuating device and the mounting level of the locking gear with largely avoiding play, it is possible to bridge different distances between the mounting level of the operating device and the mounting level of the locking gear with the actuating device disclosed above in the area between the oscillating bearing in the drive nut and its pendulum bearing head element facing the drive element of the locking gear possible to make the length of the end piece, on the one hand, and the pendulum bearing head piece, on the other hand, adjustable in length, as is known in another context, for example according to DE 705 675 C.

• daß in der axialen Ausnehmung des Bedienungshebels ein die Antriebsnuß tragender Mitnehmerbolzen undrehbar aber axial verschiebbar sitzt,
• der relativ zum Bedienungshebel in Richtung gegen das in die Antriebsnuß eingreifende Endstück der Welle unter ständiger elastischer Vorspannung gehalten ist.

Since the length-adjustable configuration of a shaft is not only problematic and expensive, but also problematic for permanently functionally reliable distance bridging, the invention proposes that

• that in the axial recess of the operating lever a driving bolt carrying the drive nut sits rotatably but axially displaceably,
• which is held relative to the operating lever in the direction against the end piece of the shaft engaging in the drive nut under constant elastic pretension.

This makes it easy to ensure that a one-piece design with pendulum movement at both ends recorded actuator shaft at each possible diffraction angle between the operating lever and the Drive element of the locking mechanism clamped elastically and therefore proper torque transmission guaranteed.

It is structurally particularly simple if the Driving pin through a in the recess of the Operating lever inserted compression spring under elastic Bias is set.

On embodiments shown in the drawing are additional training features and advantages of Actuators according to the invention in detail explained.

In Fig. 1 of the drawing are of a double-leaf window without the mullion, only the lock side Wing leg 1 of the main wing and the closure side wing height leg 2 of the secondary wing too see. The wing leg 1 carries the main wing on its inner or room-side end face 3 a Blow bar 4, while the wing leg 2 of the Secondary wing on its outer end face 5 with a Blow bar 6 is equipped.

In the closed position of the window, the overlaps Wing leg 1 of the main wing carried blow bar 4 the room-side end face 7 on the wing leg 2 of the Secondary wing, while at the same time the outer end face 8 on wing wing leg 1 of the main wing from the Wing wing leg 2 of the secondary wing attached Blow bar 6 is overlapped.

It can also be seen from Fig. 1 of the drawing that the inner blow bar 4 with its profile width 9 symmetrical to the inner total width 10 of the so-called middle joint forming wing leg 1 and 2 of main wing and Secondary wing is arranged and that the profile width 11th the outer blow bar 6 a symmetrical arrangement outer total width 12 of this middle joint. Through this Design of the wing leg 1 and 2 and the Blow bars 4 and 6 is at the closed window in Area of the so-called middle joint a plane of symmetry 13 - 13 defined, which is normal to the window level.

As for the construction of double-leaf windows and double-leaf Doors or the like. Different from case to case Profile systems made of wood, plastic, metal or Mixed constructions made of these materials are used , it is obvious that they are each other facing fold surface peripheral areas 14 and 15 of the Wing leg 1 and 2 of the main wing and secondary wing have more or less different profiles. Therefore, they also have relative to the one defined above Level of symmetry 13 - 13 more or less different Distances.

The fold surface peripheral regions 14 and 15 of the Wing leg 1 and 2 of the main wing and secondary wing are mainly used to install and accommodate the Functional fittings used. That is why inevitably that these fittings are also appropriate different relative positions to the named plane of symmetry 13 - Take 13. This applies in particular to the Locking gear of the espagnolette fittings, the usually in step grooves of the fold surface peripheral areas lie and manually by an actuator 16 must be operated. Such actuator 16 usually consist of a rosette 17, in the directly an operating lever 18 is rotatably mounted. The Actuator 16 with its rosette 17 and Operating lever 18 is on the inner blow bar 4 assembled. So that the longitudinal median plane of the rosette 17 and consequently also the axis of rotation of the operating lever 18 Cover position with the plane of symmetry 13 - 13 has.

The axis of rotation 19-19 of a drive element 20, e.g. one Pinion, in the wing leg 1 of the main wing built-in lock gear has a relatively large lateral offset position 21 to the plane of symmetry 13-13 or to the axis of rotation of the Operating lever 18, which can be bridged reliably got to.

For the purpose mentioned, in the exemplary embodiment according to FIG. 1 in the neck of the operating lever 18 as a drive nut Polygonal, in particular square recess 22 incorporated, which for the positive reception of an end piece 23 one Wave 24 is established. The free end of this wave 24 forms a rotary coupling driver for the drive element 20, e.g. the pinion, the (otherwise for reasons of simplification not shown) lock gear.

It is essential that on the one hand the end piece 23 of the shaft 24 in the polygonal, in particular square recess 22 of the operating lever 18 is pivoted, while on the other hand also the free end of the shaft 24 Pendulum bearing head piece 25. This self-aligning head piece 25 can be used as a plug-in coupling member Polygonal, in particular square recess 26 rotatably are indented, which are in alignment with the axis of rotation 19 19 in the drive element 20 e.g. the pinion of the Locking gear is provided.

Since the shaft 24 with both its end piece 23 and their self-aligning head 25 between the operating lever 18 and the drive element 20 torque transmitting Diffraction joints forms, the axis offset 21 through corresponding inclined position of the shaft 24 bridges easily at least as long as certain diffraction angles are not be exceeded significantly. The inclination of the shaft 24 is by a in the wing leg 1 of the main wing drilling made possible.

2 of the drawing, in particular, that to a polygonal cross-section, especially a square cross-section having shaft 24 of the end piece 23 and that Self-aligning head 25 each following Circumferential constriction 27 integrally formed and with a crowned end surface 28 are equipped. 2 it can be seen that the circumferential constriction 27 to the end piece 23 or self-aligning head 25 each by a steep Pyramid surface 29 is limited, to which the shaft center towards a flat conical surface 30 connects. Has been advantageous it turned out if the flanks of the pyramid and the Conical surfaces with each other about a right angle include and also the cone angle for the flat conical surface 30 between 145 ° and 150 °, for example at 148 °.

It has also proven itself if that end piece 23 and that Self-aligning head 25 of the shaft 24 at least where it is as a rotary coupling driver in the square recess 22 or 26 engage from operating lever 18 and drive element 20, the same cross-sectional shape and cross-sectional dimension have, as that between the circumferential constrictions 27th lying section of the shaft 24. Die Constrictions 27 can pass through the shaft 24 non-cutting or cutting shape, e.g. by pressing or Milling, manufacturing.

In the illustrated in Fig. 1 of the drawing The exemplary embodiment is the shaft 24 with its end piece 23 preferably non-rotatable and limited longitudinally displaceable, but cannot be detached from the square recess 22 of the operating lever 18 held while their self-aligning head 25 with the Square recess 26 of the drive element 20 in a rotationally fixed Plug-coupling connection can be brought.

The actuating device 16 according to FIG. 1 is practically a type in which the bearing rosette 17, the Operating lever 18 and the shaft 24 to a special salable unit are summarized.

In Fig. 3, however, is an actuator for the use described above to see which ones characterized in that a drive nut 31 in one Adapter piece 32 is rotatably mounted, which is simply under the bearing rosette 33 of a commercially available operating lever lets sit. The adapter piece 32 is (not shown) passages for the fastening screws and possibly also for coaxial fixing pins of the control lever bearing rosette 33 provided. In the drive nut 31 is on the one hand the shaft 24 with its end piece 23 similar to that Fig. 1 pendulum, but rotatably and non-detachably. On the other hand, the drive nut 31 has a square neck, with which a corresponding square recess 22 of commercially available operating lever 34 in plug connection can be brought.

In all cases, the circumferential constrictions 27 delimiting pyramid surfaces 29 and conical surfaces 30 achieved that on the one hand between the square recess 22nd and the end piece 23 and on the other hand between the Self-aligning bearing head piece 25 and the square recess 26 Diffraction joints arise that with diffraction angles of 10 ° a permanently jerk-free and therefore smooth-running Ensure torque transmission.

In the area between the circumferential constrictions 27, the If necessary, shaft 24 can also be adjusted in length Receive design.

It is also worth mentioning that the circumferential constrictions 27 flat conical surfaces 30 bounding the shaft center when installing the shaft 24 between the operating lever 18 Actuator and the drive member 20 of the Locking gear support function can take over by each special - in the area of each bend Flexor joint - on the facing face of the Apply control lever 18 and drive element 20.

From the above it follows that Part of the actuating device essential to the invention is the specially designed shaft 24. she offers on the one hand by their specially designed end piece 23 and on the other hand, by their suitably designed self-aligning head 25 the possibility of immediate formation of two torque transmitting articulated joints alone positive engagement connection with an operating lever 28 or a drive nut 31 and by positive Engagement connection with the drive element 20 one Locking gear.

4 is in one Bearing rosette 33 is a commercially available operating lever 34 rotatably supported, in which an axial square recess 22nd is molded. Sits in this square recess 22 non-rotatable, but axially displaceable, a driver pin 35, at its front end a drive nut 31 with a Driver recess 37 has. With this driver recess 37 the drive nut 31 is a shaft 24 via an end piece 23rd in a diffraction joint that transmits torque Connector. On the other hand, this wave 24 is over one Self-aligning head 25 also forming a torque transmitting diffraction joint with the Drive element 20, e.g. B. a pinion, over the square recess 26 associated.

The shaft 24 with its end piece 23 and the self-aligning bearing head piece 25 does it by appropriate inclination easily possible, a lateral axis offset between the Square recess 26 of the drive element 20 and To bridge the driver recess 37 in the drive nut 31, as is clear from the drawing.

The axially displaceable and non-rotatable in the Square recess 22 of the operating lever 34 seated Driving pin 35 is against this relative to the end piece 23 of the shaft 24 which engages in the drive nut 31 kept under constant elastic tension. This Elastic pre-tension can be applied in the axial direction Square recess 22 of the operating lever 34 used Compression spring 36 are brought out. It ensures that on the one hand between the end piece 23 of the shaft 24 and the Drive nut 31 and on the other hand between the self-aligning head 25 and the square recess 26 in the drive element 20 completely automatically a permanently secure Coupling connection is maintained, regardless of which is due to the lateral axis offset between the Control lever 34 and the drive element 20 determine Oblique position of shaft 24.

Although the usability of the Actuators only in connection with double leaf Windows and doors or the like explained without a mullion has been possible to use without further also on windows and doors or the like with at least an outward opening wing. In such a case then the mounting arrangement of the actuator on the outward opening wing analogous to FIGS. 1 and 2 of DE 917 053 C.
