Description

The invention relates to a fitting for a building door according to the preamble of claim 1. The fitting has a handle, in particular a door handle, and a transmission element which can be brought into operative connection with a lock and to which a torque of the handle is transferable, wherein the Transmission element is mounted in the fitting such that a first of the handle facing away from the end of the transmission element is movable in a plurality of spatial directions.

As a result, the advantage is achieved that the transmission element has a large freedom of movement, so as to compensate for tolerances of the building door and / or the castle. These are, in particular, the end of the transmission element facing away from the handle, which has to be inserted as vertically as possible into the building door for installation. The fitting is thus adaptable for different installations of building doors, thus errors can be compensated.

It is known that fittings for building doors have transmission elements to actuate a lock of the building door. The transmission element is used in particular to transmit torque from the handle to a lock. For this purpose, the transmission element projecting from the back of a fitting body and must be arranged for mounting almost vertically.

Disadvantageously, the installation of the fitting on a building door on site can be impeded and hindered in the case of known fittings, if, for example, the transmission element can not be introduced into a vertical angle due to manufacturing tolerances or faulty installation, in particular the building door or the lock.

The publication DE 24 35 212 A1 discloses a mechanical fitting according to the preamble of claim 1.

The publication EP 1 039 072 A2 discloses a lock, in particular furniture lock with an actuating handle which is connectable via an engageable between a coupled and a disengaged position, electromechanical coupling device with an actuator which is engaged with a movable between an open and a closed position latch mechanism, wherein a in the Operating handle arranged gear is provided, in which the electromechanical coupling device is integrated, which switches the transmission between a disengaged freewheeling position and a coupled, force transmitting position, wherein the actuator for the locking mechanism as positively connected to the output side of the transmission, on the transmission cantilevered square is trained.

The invention has for its object to provide a fitting that at least partially overcomes the above-mentioned disadvantages, and in particular to provide a fitting available in which the fitting with the transmission element for Different, complicated installation conditions are quickly and easily customizable.

The above object is achieved by a fitting with the features of independent claim 1.

According to the invention, the fitting is an electromechanical fitting which has a coupling element, wherein the coupling element is movable into an engaged position, in which the coupling element is in operative connection with the transmission element or can be brought into operative connection with the transmission element by a movement of the handle and a torque from the handle is transferable to the transmission element, wherein the coupling element is movable to a disengaged position in which the coupling element is out of operative connection with the transmission element and the handle is movable with the coupling element, without torque on the transmission element to transferred, wherein in the engaged position, the coupling element acts via a counter-coupling element on the transmission element, wherein the counter-coupling element is positively and / or non-positively connected to the transmission element.

The fitting has in particular next to the transmission element and the handle on a fitting body. Optionally, the fitting may have at least one fastening element for fastening the fitting to the building door. Alternatively, the fitting can be connectable with at least one fastening element.

The transmission element serves to transmit a torque from the handle to a lock. For this purpose, the transmission element protrude from a rear side of the fitting body. The transmission element can be adapted to the lock with a first part, in particular with the first end, which serves for insertion into the lock. The transmission element can, for. B. in the castle, especially in a nut of the castle, be plugged. The first part of the transmission element may be formed as a polygon, in particular as a square. Alternatively, the first part z. B. be formed as a piece of sheet metal. By transmitting the torque, it is possible in particular to actuate a latch and / or a bolt of the lock. Furthermore, it is optionally possible for the transmission element to connect to a handle on an opposite side of the building door.

The terms "before", "behind", "above", etc. are used below in such a way as it corresponds to an installed condition of the fitting from the viewpoint of a viewer. Unless defined otherwise, in particular the terms "axial" and "radial" refer to axes of symmetry of individual elements.

Under several spatial directions are understood directions that are transverse to each other. Thus, the first end of the transmission element is not only movable on a straight or curved line, but also deviating from the line. For example, the first end not only from top to bottom, but also to the right and left or obliquely right and obliquely left or obliquely up and down obliquely movable. In particular, a straight or curved surface is spanned by the movement of the first end.

The fitting body serves for arrangement on a building door. Likewise, the fitting body can be arranged on other doors with planar outer surfaces such as interior doors of ships or trains. The fitting body is particularly suitable to rest with the back on an outer surface of the building door or alternatively be wholly or partially embedded in the building door. The fitting body can be arranged outside a lock case of a lock. The fitting body can be designed in particular as a door plate or as a rosette. The fitting body can be used as dummy shield, d. H. be configured without a receiving opening for a lock cylinder, or with a receiving opening for a lock cylinder.

The fitting body can serve for the storage of the handle. Additionally or alternatively, the fitting body may have at least one door attachment receptacle for receiving a fastening element which serves for fastening to the building door.
It is also conceivable that a maximum deflection angle of the transmission element in a range of 0.5 ° to 5.0 °, preferably in a range of 1.0 ° to 3.0 °, particularly preferably in a range of 1.3 ° to 2.0 °, wherein the deflection angle of the angle between a deflected transmission element and a vertical arrangement of the transmission element at a rear side of the fitting body of the

Fitting is. Due to the height of the maximum deflection angle, the advantage is achieved that the fitting according to the invention can also be mounted and is functional if a substantially vertical arrangement of the transmission element is not possible. Thus, even with manufacturing tolerances and assembly errors in the building door or the castle a reliable mounting of the fitting can be done. In addition, since the requirements for accurate positioning are greatly reduced, assembly can be carried out more quickly and easily. The deflection angle indicates the deflection between the transmission element relative to a vertical arrangement of the transmission element. In this case, the vertical arrangement of the transmission element is in particular perpendicular to a front and / or rear side of the fitting body.

In a further possibility, it can be provided within the scope of the invention for the maximum deflection angle to be able to be absorbed by the transmission element in a plurality of spatial directions. Thus, the transmission element can be inclined in several spatial directions to an equal extent.

Another advantage may be provided in the context of the invention that the transmission element is movable so that by the transmission element inmatable positions on a cone, in particular a straight circular cone lie. Thus, the first ends of the transmission element can be occupied by the transmission element ingestable positions z. B. are on a spherical segment. This is a particularly uniform deflection. Possibly, there may still be positions in which the transmission element can be deflected further than the cone, in particular the straight circular cone.

Preferably by the transmission element ingestible positions at maximum deflection on a cone, in particular a straight circular cone. So z. B. are the first ends of the transmission element at all ingestible by the transmission element positions on a spherical segment. In this case, in particular, the maximum deflection angle can correspond to half the opening angle of the circular cone.

In a further possibility can be provided in the context of the invention that the transmission element is arranged on a cover, in particular a bearing plate, which at least partially forms the back of the fitting body and / or covers a rear side of a support of the fitting body, in particular the cover the Transfers axially and / or radially transmission element. The terms "axial" and "radial" are to be understood in relation to the vertical arrangement of the transmission element with respect to the back. The axial bearing through the cover is in particular to the rear. To the front, an axial mobility can be limited in particular by the at least indirect contact with the carrier of the fitting body.

It is also conceivable that the cover, in particular the bearing plate, reversibly detachable, in particular positive and / or non-positive, is arranged on the carrier of the fitting body. The cover can be attached to the carrier, for example, releasably by fastening means such as screws or clips.

The transmission element must be adapted to the lock as described. If the fitting is to be used in different locks, so different transmission elements must be kept. By reversibly releasable cover it is possible to open the fitting and replace the transmission element according to the specification of the castle. The rest of the fitting can remain unchanged.

So that transmission elements with different first ends can be mounted in the same fitting body, it is provided in particular to design the end of the transmission element mounted in the fitting body in the same way and to adapt the first end to the respective lock.

Also, for maintenance purposes, the removability of the cover allows easy accessibility and a simple replacement of components, such as the transmission element allow.

Advantageously, it can be provided in the context of the invention that the transmission element is widened at an end mounted in the fitting body of the transmission element and is held by the broadening in the fitting body. The distribution is in particular adapted to the fitting body such that a bearing of the transmission element on the fitting body, in particular on the cover, takes place. In this way, holding or supporting the transmission element on the fitting body without other fastening means or holding means may be possible. Advantageously, it can be provided in the context of the invention that the transmission element is widened at an end mounted in the fitting body of the transmission element and is held by the broadening in the fitting body. The distribution is in particular adapted to the fitting body such that a bearing of the transmission element on the fitting body, in particular on the cover, takes place.

Furthermore, it can be provided in the context of the invention that the cover, in particular the bearing plate, has a circumferential collar for supporting the transmission element, wherein in particular the collar has a cylinder jacket-shaped portion and an adjoining tapered portion. Thus, in particular, a ball-joint-like mounting of the transmission element takes place. In addition, the freedom of movement of the transmission element can be limited in particular by the tapered section. Thus, the transmission element can be securely and reliably held and stored in its predetermined position in the fitting body.

Furthermore, it can be provided in the context of the invention that the collar and / or mounted in the fitting body end of the transmission element are designed rotationally symmetrical. In this way, the mobility of the transmission element can be made possible such that the transmission element is movable in a plurality of and / or all spatial directions. It also ensures proper functioning in the transmission of torque.

According to the invention, the fitting is designed as an electro-mechanical fitting, which has a coupling element which is moved by an electric drive. By the coupling element of the fitting can be designed such that a mechanical coupling of the handle with a lock that can be connected to the fitting, can take place, so that a torque from the handle to the lock is transferable. For this purpose, the coupling element can be moved into an engaged position, in which the coupling element is in operative connection with the transmission element or can be brought into operative connection with the transmission element by a movement of the handle and a torque can be transmitted from the handle to the transmission element. In addition, by the electric drive, a decoupling of the handle from the lock take place, in which a movement of the handle is decoupled from the lock. Here, the coupling element is movable to a disengaged position in which the coupling element is out of operative connection with the transmission element and the handle is movable with the coupling element without transmitting torque to the transmission element.

The fitting can serve the access control. In particular, a coupling takes place only after an authentication of an authorized user.

The handle is particularly operable both when the coupling element is in the disengaged position and when the coupling element is in the engaged position. The coupling element can be connected to the handle at least indirectly. The coupling element can rotate in particular during a rotation of the handle. According to the coupling element acts in the coupled position via a counter-coupling element on the transmission element, wherein the counter-coupling element is positively and / or non-positively connected to the transmission element.

Thus, in the disengaged position, the handle with the coupling element can be out of operative connection with the counter-coupling element of the fitting. In the engaged position that stands Coupling element with the counter-coupling element in operative connection or can be brought by a movement of the handle in operative connection with the counter-coupling element. The latter applies, for example, if a clearance is provided between the coupling element and the counter-coupling element. In the operative connection, the coupling element and the counter-coupling element are positively connected with each other.

Preferably, the fitting has a transmitting and / or receiving unit with which an authentication code can be received wirelessly. The transmitting and / or receiving unit may comprise an antenna. The authentication code can be transmitted from an external portable authentication transmitter to the transmitting and / or receiving unit. The authentication provider can passively, d. H. without own energy supply, or active, d. H. be equipped with its own energy supply. Thus, the authentication encoder can be designed as a passive or as an active transponder. After transmission of the authentication code, the authentication of a user can be checked.

Preferably, a clearance is provided between the counter-coupling element and the transmission element. Through the game, the bearing clearance of the transmission element is made possible, wherein the counter-coupling element does not also have to adapt to the conditions of the castle.

The counter-coupling element can, for example, engage in the transmission element. In this case, provision is made in particular for the counter-coupling element to have a smaller size or a smaller diameter than the transmission element. In particular, an effective diameter, with which the counter-coupling element engages in the transmission element, be less than the diameter of a second end of the transmission element for receiving the counter-coupling element. To engage in the transmission element, the counter-coupling element may in particular have a survey. The transmission element may have a recess into which the counter-coupling element can engage.

The first end of the transmission element facing away from the counter-coupling element is movable independently of the counter-coupling element in a plurality of spatial directions. In this case, in particular, the cover member, the counter-coupling element on the carrier at least axially, d. H. fore and aft, fix. For this purpose, the counter-coupling element has a flange-like edge. The counter-coupling element can in this case be arranged in a counter-coupling element receptacle of the carrier. By fixing a spatial orientation of the counter-coupling element to the coupling element remain constant despite deflection of the transmission element.

Furthermore, the counter-coupling element can be guided on a mounting element which serves to guide the coupling element. By these measures, the coupling element and the counter-coupling element can be well positioned to each other.

Further, the cover member may comprise a part of a spring retainer, wherein the spring retainer supports a spring, which serves for moving the handle in a rest position in which the handle is unactuated. The cover thus serves, for example, for supporting and / or holding the spring, the transmission element and / or the counter-coupling element. It may in particular be in contact with the counter-coupling element and thus cause a fixation and / or a holding of the counter-coupling element.

It is also conceivable that the counter-coupling element and the transmission element are connected via a particular curved toothing, wherein in particular the toothing on the counter-coupling element has at least six teeth, preferably at least eight teeth. Due to the toothing a good torque transmission can be achieved. The toothing can be provided in particular at the elevation of the counter-coupling element, and engage in a complementary toothing (in particular a negative-form) in a recess of the transmission element. Due to the curved toothing can also in a deflection of the transmission element, the Transfer element lie flat against the counter-coupling element. As a result, a good transmission of the torque is possible.

It may be that the handle is locatable in both a first leftward orientation and a second leftward orientation in the fitting. It may be that the coupling element in the first orientation of the handle occupies a position which is geometrically different from the position occupied by the coupling element in the second orientation of the handle.

This is z. B. for the case conceivable that the coupling element is guided in the mounting element. In particular, the mounting element may have a stop element which rests in the first orientation of the handle in the rest position on a second stop of the carrier and in the second orientation of the handle in the rest position on a first stop of the carrier. Thus, the stop element is arranged according to the respective orientation of the handle, the mounting element and thus the coupling element in at least two different positions with respect to the handle and / or the carrier can be arranged.

Accordingly, the mating coupling element must be adjusted so that the coupling element can be moved into the engaged position, in which the coupling element is positively connected to the mating coupling element, in particular engages in the counter-coupling element. Thus, it may in particular be the case that the counter-coupling element can assume at least two different positions with respect to the carrier and / or the transmission element. In particular, the positions are rotated by an abutment angle, which passes through the stop element of a concern to the first stop until it abuts against the second stop. Thus, the transmission element can retain its geometric orientation which the transmission element requires for connection to the lock.

If the mating coupling element and the transmission element are intermeshed, then the angle between two teeth of the toothing can be an integer divisor of the abutment angle.

The coupling element may preferably engage in the engaged position in the counter-coupling element, in particular centrally. In the fitting body, the coupling element and the counter-coupling element may lie on a common axis. Additionally or alternatively, the counter-coupling element and the transmission element can lie on a common axis. As a result, an arrangement in a small space is possible. In particular, the handle, the coupling element, the counter-coupling element and the transmission element lie on a common axis. The coupling element can be arranged at least in the disengaged position partially in the handle. This allows a flat fitting.

In the engaged position of the coupling element, the coupling element is in particular spaced from a lying in the direction of movement of the coupling element component, in particular the transmission element arranged. As a result, a seizing of the coupling element is avoided. In order to still allow deep engagement of the coupling element in the counter-coupling element, the counter-coupling element may have a through opening.

Furthermore, although the transmission element and the counter-coupling element may be mounted axially to one another, a positive and / or non-positive connection, in particular the toothing, of the counter-coupling element with the transmission element is preferably formed radially. In this way, a distance of the coupling element in the engaged position to the underlying transmission element can be made large. Furthermore, this makes it possible to save space in the interior of the building door. The toothing of the counter-coupling element may be formed around the circumference of the counter-coupling element, which engages in a recess of the transmission element.

Preferably, at least one sensor is provided for identifying at least one position of the coupling element and a control unit for controlling and / or regulating the drive in dependence on a signal transmitted to the control unit of the sensor in the fitting. The Control unit stops in particular on the basis of a signal transmitted to the control unit of the sensor to the drive when the coupling element has reached the position to be reached of the coupling element, that is, the engaged and / or disengaged position. Thus, the engaged position can be selected spaced from a arranged behind the path component.

Alternatively or additionally, a spindle and / or a worm, via which the drive moves the coupling element, may be equipped with a spindle and / or worm end which terminates a movement of the coupling element in the engaged position.

In the Figures 1 and 2 an inventive fitting 1 is shown. The fitting 1 has a fitting body 2 according to the invention, a handle 30, a transmission element 26 and fastening elements 60. The handle 30 is designed as a door handle. The handle 30 has a connecting piece 32 for abutment with a fitting body 2 and an angled piece 32 of the connecting piece 31.

The transmission element 26 serves to be inserted into a nut of a lock and to transmit a torque of the handle 30 to the lock and thus to actuate a latch and / or a bolt. For this purpose, an end 90 of the transmission element of the nut is adapted. The fasteners 60 are used to attach the fitting 1 to a building door.

As in the FIGS. 3 to 5 illustrated, the handle 30 can take various positions. The handle 30 may assume a first leftward orientation V, as in FIG FIG. 3 shown. The handle 30 may be moved from the first orientation V to a second rightward orientation VI, which is shown in FIG FIG. 4 is shown, change. For this purpose, however, the fitting 1 must be at least partially dismantled. In a ready-assembled state of the fitting 1, the handle 30 can in each case only between a rest position I, as in FIG. 3 for the first orientation and in FIG. 4 shown for the second orientation with solid lines, and an operating position II, as in FIG. 3 for the first orientation and in FIG. 4 for the second alignment shown with dashed lines. The positions of the handle 30 which can be received in the assembled operational state are referred to as operating positions. An operating angle BW is defined as the angle between the rest position of the handle and the operating position of the handle. For example, the operating angle can be 45 °. In the FIG. 5 a mounting position III of the handle 30 is shown, which is not ingestible in a mounted state of the fitting 1. The mounting position III is taken both during a first assembly of the fitting 1 and during a change of orientation of the handle 30.

In FIG. 6 Parts of a fitting body 2 according to the invention are shown in an exploded view. The fitting body 2 is formed with a front side 101, a back side 102 and side surfaces 103, 104, 105, 106, as in FIGS Figures 1 and 2 shown. The fitting body 2 has a carrier 10. The carrier body is formed with a front side 111, a rear side 112 and sides 113, 114, 115, 116. The carrier 10 is monolithically formed from a metal. The carrier 10 has a carrier body 19 and a bearing element 11. The bearing element 11 protrudes forward from the carrier body 19. The bearing element 11 serves to support the handle 30. Here, the bearing element is received in the handle 30. Between the bearing element 11 and the handle 30, a bearing sleeve 33 is provided, which serves for the haptic pleasant operation of the handle 30 and to reduce the wear of the handle 30 and the bearing element 11.

On the front side 111, the carrier body 19 is covered by a diaphragm 9. The diaphragm 9 is composed of diaphragm elements 3, 4, 5 and another, in FIG. 1 shown aperture element 49, which is used in the aperture element 5, together. On the rear side 112 close to the carrier cover elements 6, 7 at. The diaphragm elements 3, 4, 5, 49 and the cover elements 6, 7 are each formed separately from each other.

As in FIGS. 1 and 2 represented, at least form the diaphragm element 3, 4 a flat, projection-free surface. Only around the handle 30 around can the aperture 9 have a slight elevation, as in FIG. 7 shown.

The fitting 1 is designed as an electromechanical fitting 1. For this purpose, the fitting 1 a drive 22 which is designed as an electric motor, on. Via a spindle 23, the drive 22 moves a coupling element 24, which is guided in a mounting element 20, as in the FIGS. 7 and 8th shown. The coupling element 24 can be in an engaged position X, the in FIG. 7 is shown to be moved. In the engaged position X, the coupling element 24 engages in an opening 73 of a counter-coupling element 25 of the fitting body 2. In this case, the counter-coupling element 25 circumferentially surrounds the coupling element 24.

The mounting member 20 and the handle 30 are rotatably connected to each other, in particular toothed, as in the FIGS. 9 and 10 shown. Because the coupling element 24 is guided in the installation element 20, the coupling element 24 moves with a rotation of the handle 30 from a rest position I into an actuation position II with the handle 30. Thus, a torque from the handle 30 transmits to the coupling element 24. If the coupling element 24 engages in the counter-coupling element 25, the torque can be transmitted to the counter-coupling element 25 and to the non-rotatably connected to the counter-coupling element 25 transmission element 26. Thus, upon actuation of the handle 30, the torque may act on the lock.

As in FIG. 18 illustrated, a clearance between the coupling element 24 and the counter-coupling element 25 is provided. Therefore, it may be that the User must first move the handle 30 before in the engaged position X, the coupling element 24 transmits a torque to the counter-coupling element 25.

In a disengaged position XI, which in FIG. 8 is shown, the coupling element 24 is disengaged from the counter-coupling element 25. Even in the disengaged position XI, the handle 30 can be actuated. The coupling element 24 also rotates with the handle 30 in the disengaged position XI. However, a torque in the disengaged position XI can not be transmitted to the counter-coupling element 25. Thus, a movement of the handle 30 has no effect on the lock.

In the FIG. 8 an intermediate position XII of the coupling element 24 is shown in dashed lines, in which the coupling element 24 is located when the drive 22 tries to move the coupling element 24 in the engaged position X, but not due to an already made rotation of the coupling element 24 in the counter-coupling element 25th can engage, but abuts the counter-coupling element 25.

So that the fitting body 2 is made as flat as possible, the drive 22 and a in FIG. 23 illustrated battery compartment 34 received in the handle 30. The battery compartment 34 serves to store energy storage 57, in particular batteries or accumulators, in an operational state of the fitting 1, with the aid of which the drive 22 can be supplied with electrical power. Also, the coupling element 24 is at least partially in the handle 30, as in the FIGS. 7 and 8th shown. The handle 30 is designed to be hollow. In particular, the coupling element 24, the counter-coupling element 25, the transmission element 26 and the handle 30 are located on a common axis 120.

The drive 22, a motor pocket 21 for the drive 22 and the coupling element 24 are received in the mounting element 20, as in the FIGS. 7 to 10 shown. The mounting element 20 is rotatably mounted in the hollow bearing element 11. In this case, the installation element 20 projects beyond the Bearing element 11 forward, as in FIG. 15 represented so that positive locking means 96 of the mounting element 20 can form a positive connection with positive locking means 58 of the handle 30, as in the FIGS. 9 and 10 shown. The mounting member 20 is also partially disposed in the hollow handle 30 here. Also, the mounting element itself has a through hole 118 for supporting the motor bag 21 with the drive 22 and for guiding the coupling element 24, as in the FIGS. 7 . 11 and 22 shown. In this case, the passage opening 118 is in each case partially adapted to the motor pocket 21 or the coupling element 24.

The counter-coupling element 25 is received directly in a mating coupling element receptacle 63 of the carrier 10 for the counter-coupling element 25.

For the drive 22 to move the coupling element 24 into the engaged position X, an authorized user must first have been authenticated. For this purpose, the fitting 1 has a transmitting and receiving unit with which an authentication code can be received wirelessly. The transmitting and receiving unit may be an antenna 51, which in FIG. 23 is shown schematically. The authentication code can be transmitted from an external portable authentication transmitter to the transmitting and receiving unit. A control unit 56, which is arranged on a printed circuit board 50, checks the authentication code and compares it with a comparison code or a default. The control unit 56 is in FIG. 23 covered by the board 68 and therefore shown only dashed. If the authentication code and the comparison code match or if the authentication code corresponds to the specification, the control unit 56 causes the drive 22 to move the coupling element 24 in the direction of the engaged position X. The control unit controls and / or controls the drive 22.

The antenna 51 is arranged on a circuit board 68. As in the FIGS. 15 and 17 shown, the board is arranged with the antenna 51 within the carrier 10. In this way, a particularly flat fitting 1 can also be achieved.

As in the Figures 1 and 2 shown, the carrier 10 on three side surfaces 103, 104, 105 visible. Thus, material for the aperture 9 can be saved. In particular, three sides 113, 114, 115 of the carrier 10 are completely visible. The carrier 10 adjoins the visible side surfaces 103, 104, 105 directly to the aperture 9. The panel 9 terminates flush with the carrier 10 on the visible sides 113, 114, 115. Thus, the carrier 10 is invisible on the front side 101 and does not need to be surface treated on the front side 111 for aesthetic reasons.

At a lower side surface 106, the lower side 116 of the carrier 10 is completely covered. The lower side surface 106 is rounded.

An upper first diaphragm element 3 and a lower second diaphragm element 4 are fastened to the carrier 10 via a positive and / or non-positive connection. In this case, the form and / or adhesion within the carrier 10. This can be dispensed with in the installed state of the fitting 1 visible grub screws for fixing the aperture elements 3, 4.

The first panel member 3 is formed as a flat plate, from the form and / or frictional engagement means 8 protrude rearwardly, as in the FIGS. 6 and 16 shown. The second panel member 4 is designed as a bent only in one end plate, protrude from the form and / or frictional engagement means 8 back executed.

The second diaphragm element 4 is made of metal. During production, the second panel element 4 only has to be bent and not deep-drawn. Thereafter, the form and / or adhesion means 8 can be welded. As a result, a particularly inexpensive production is possible.

The first diaphragm element 3 covers the antenna 51. In order for signals to reach the antenna 51 well, the first diaphragm element 3 is made of a plastic. The first panel element 3 is clipped into the carrier 10. For this purpose, the carrier 10 corresponding receptacles 97, as in FIG. 16 shown on. The connection between the first panel element 3 and the carrier 10 can only be detached from the rear side 112 of the carrier 10.

As a result, the first panel element 3 can not be removed by an unauthorized user.

Also for the reduction of electromagnetic damping, the first cover 6, which covers the antenna 51, made of plastic. The first cover element 6 is glued to the rear side 112. The first cover element 6 projects beyond the rear side 112 of the carrier 10. In this way, an electrically conductive connection between the carrier 10 and a metallic building door in the region of the antenna 51 can be avoided.

So that no electrically conductive paths are present around the antenna 51 in the carrier 10, the carrier 10 in the region of the antenna 51 has an electronic receptacle 13 configured as a passage opening. The electronics receptacle 13 serves as a receptacle for the circuit board 68 and the printed circuit board 50. In addition, the carrier 10 has a gap 84 through which an electrically conductive connection is interrupted around the antenna 51, as in the FIGS. 6 . 15 and 16 shown.

The circuit board 68 with the antenna 51 is formed electrically insulated from the carrier 10. The antenna 51 is attached only to the carrier 10 via the circuit board 50, as in FIGS FIG. 15 and 17 shown. The printed circuit board 50 and the antenna 51 are connected to each other via electrically conductive connections.

In addition to the antenna 51 for receiving the authentication code, the board 68 on an unillustrated antenna element for receiving the comparison code or the default. Signals are received at a higher frequency than the antenna 51 via the antenna element.

The second cover member 7 is reversibly releasably attached to the carrier 10, in particular screwed. As a result, a non-destructive access to the behind the second cover element 7 lying elements 40, 41, 42, 20, 25, 43 is possible. It can be provided for recesses on the cover 7 and the carrier 10, which can accommodate fastening means such as screws for releasably attaching the cover 7 to the carrier 10.

The first and the second panel element 3, 4 enclose the handle 30 less than half, so that the first and the second panel element 3, 4 can be removed from the fitting body 2, without the handle 30 must be disassembled.

The second panel member 4 is attached via a positive and non-positive connection to the carrier 10, which is releasable by vertical, downwardly directed displacement. For this purpose, in recordings 99 of the carrier 10, in the FIGS. 6 and 25 are shown, spring washers 27 which in the FIGS. 6 and 16 are shown, inserted, in which the form and / or adhesion means 8 of the second diaphragm element 4 can intervene. For this purpose, the form and / or adhesion means 8 of the second diaphragm element 4 are formed as provided with a mushroom head pins. The spring washers 27 are passable in a lower region for the mushroom heads. In an upper region of the spring washers 27, the mushroom heads are held positively in front, while the spring washers 27 clamp the mushroom heads such that the second diaphragm element 4 is held. If the clamping force is overcome by a user, the user can move the second diaphragm element 4 downwards and then remove it.

The carrier 10 has in the region of the second diaphragm element 4 door mounting receptacles 14, 15, as in FIG. 25 shown on. Thus, after disassembly of the second aperture element 4, the fasteners 60 are accessible. Thus, it may be desirable for easy assembly or disassembly that the fasteners 60 can only be reached by moving and removing the second panel element 4. This applies z. B. for arranged on the inside of building doors fittings. Also, this may apply to arranged on the outside of building doors fittings 1, unless the fasteners 60 are not detachable from the front 111 in the installed state. For example, the fasteners 60 may be detachable only from the rear side 112 of the carrier 10. Thus, it is also conceivable to provide an emergency lock cylinder (not shown) behind the second panel element 4.

Alternatively, for simple manipulation reasons, the simple access to the fastening elements 60 should be prevented. For this purpose, a securing element (not shown) may be arranged under the form and / or force-locking means 8 of the second diaphragm element 4 and prevent a displacement of the second diaphragm element 4 by a positive connection. Alternatively or additionally, an opening 98 for a lock cylinder may be formed in the second panel element 4, as in FIG FIG. 15 shown. The lock cylinder (not shown) can protrude through the opening in a built-in state of the fitting 1 and prevent downward displacement of the second panel element 4.

Apart from a possible opening 98 for the lock cylinder, the first and the second diaphragm element 3, 4 on a continuous surface.

The carrier 10 has a lock cylinder receptacle 12, as in the FIGS. 6 and 25 shown. The designed as a through hole lock cylinder receptacle 12 is dimensioned such that a lock cylinder can be pushed through at different distances to the handle 30. The emergency lock cylinder can be completely hidden behind the second aperture element 4. Otherwise, the lock cylinder can protrude through the second diaphragm element 4, wherein the opening 98 of the second diaphragm element 4 is adapted to the size of the lock cylinder. For different distances from lock cylinders to the handle 30 second aperture elements 4 must be kept with corresponding openings 98. However, the remaining fitting 1 does not have to be adapted to the different distances between a lock cylinder and the handle 30.

If different distances of the fastening elements 60 from one another and / or to the handle 30 are conceivable, then the corresponding door fastening receptacle 14, 15 can be designed such that the fastening elements 60 can be variably placed. Thus, the door mounting receptacles 14 are each configured as a slot, as in FIG. 25 shown.

The first panel member 3 and the first cover member 6 form a protective downwardly open housing around the board 68. As in FIG FIG. 25 shown, the housing is open at the bottom, so that air circulation is achieved. As in FIG. 6 and 16 illustrated, the first panel member 3 an angled protection means 74 which is arranged in the gap 84. The gap 84 is formed rising from outside to inside.

In FIG. 23 electrical conductors 37, 38, 91, 92 are shown. The first electrical conductors 37, 38 are arranged in the handle 30 and designed to transport electric current from two poles of the energy store 57. The first electrical conductors 37, 38 lead through the handle 30 from the battery compartment 34 to the printed circuit board 50. Further lead from the printed circuit board 50 second electrical conductors 91, 92 to the drive 22. The first electrical conductors 37, 38 supply the printed circuit board 50 with electricity. The drive 22 is supplied with electrical current via the first and second electrical conductors 37, 38, 91, 92. In this case, the drive 22 receives electrical current only via the printed circuit board 50. All described electrical conductors 37, 38, 91, 92 are arranged within the handle 30 and within the fitting body 2.

The first and second electrical conductors 37, 38, 91, 92 are mechanically interconnected within the connector 32, with the electrical conductors 37, 38, 91, 92 isolated from each other. This applies in particular to the area in which the mounting element 20 is arranged.

The installation element 20 supports the first and second electrical conductors 37, 38, 91, 92. For this purpose, the installation element 20 has a boundary region 95. The restriction region 95 is designed as a smooth section of a cylinder jacket surface. The limiting region 95 is designed in such a way that the electrical conductors 37, 38, 91, 92 rest against the limiting region 95 in each operating position of the handle, as in FIGS FIGS. 9 and 10 shown. This applies to both the first and the second orientation V, VI.

In order to partially form the boundary portion 95, the interlocking means 96 are not formed around the entire periphery of the installation member 20, as in FIGS FIGS. 9, 10 and 22 shown. Also, the interlocking means 58 are interrupted as in FIGS FIGS. 9, 10 and 22 shown to form a region for guiding the electrical conductors 37, 38, 91, 92. The interlocking means 58 are interrupted twice, so that for both the first and the second orientation V, VI of the handle 30, a region for guiding the electrical conductors 37, 38, 91, 92 results.

In the area of the bearing element 11, the electrical conductors 37, 38, 91, 92 are arranged rotationally fixed. For this purpose, a guide 93 is provided, which is formed laterally from a passage 94 of the bearing element, which in the FIGS. 9, 10 and 26 is shown. Above the guide 93 is limited by the bearing sleeve 33. At the bottom, the boundary portion 95 closes the guide 93, as in FIGS FIGS. 9 and 10 shown.

The battery compartment 34 is disposed in the handle 31. Here, the energy storage 57 can be replaced by removing a cover 25. The lid 35 can only be opened via a special tool. The battery compartment 34 ends in front of the cover 35. The battery compartment 34 is dimensioned such that the energy storage 57 projects beyond the battery compartment 34 into the cover 35. In this case, the cover 35 is provided for the electrical conduction of the electrical current of at least one energy store 57.

The cover 35 is adapted to the circumference of the energy store 57 such that a secure hold of the energy store 57 and a secure electrical contact with the lid 35 are possible. In this case, a planar projection in the cover 35 and a circumference of the cover 35 are adapted to one another such that the energy store 57 contacts a pole of the energy store 57 even if the movement of the energy store 57 is radial relative to an axis of the handle 31. Thus, the energy storage 57 can rest against a flat projection of the lid 35 even with a shaking movement. In particular, the cover 35 is electrically connected to the negative pole of the energy storage 57.

Within the handle 30, an electrical conductor 36, in particular a metal strip 36 is provided. This is disposed inside the handle 31 of the handle 30, and passes the electric current from the lid 35 to the battery compartment 34 over. In order to ensure a stable contact with the cover 35, the electrical conductor 36 is designed spring-loaded and is in particular resiliently against the cover 35. In this case, the electrical conductor 36, in particular the metal strip 36, is formed such that upon insertion of the lid 35 into the handle 31 of the electrical conductor 36 is increasingly elastically bending.

Furthermore, a spring element 59 is arranged in the battery compartment 34, which exerts a mechanical force for fixing to the energy storage 57 and presses the energy storage 57 in particular against the cover 35. Here, a shoulder is provided in the handle 31 against which the battery compartment 34 abuts.

In the FIGS. 11 to 14 are rear views of the fitting 1 from the FIGS. 3 and 4 shown, wherein the FIGS. 11 and 12 a first orientation V of the handle 30 and the Figures 13 and 14 a second orientation VI of the handle 30 correspond. Here, each of the transmission element 26, the counter-coupling element 25 and the cover 7 are not shown, so that the fitting 1 is shown partially open.

As in the FIGS. 11 to 14 illustrated, the fitting body 2, a spring 40. The spring 40 serves to move the handle 30 in the rest position I. The spring 40 is connected via a lever 42 indirectly with the handle 30. As a result, a sufficiently high torque can be applied to the handle 30. The spring 40 is designed as a compression spring. The lever 42 is connected via an extension with the handle 30. In this case, the extension corresponds to a stop element 43. The stop element 43 is part of the monolithic built-in element 20 and thus rotatably and reversibly releasably connected to the handle 30.

The lever 42 is inserted in the stop element 43 and thus rotatably supported. Here, the lever 42 in the first orientation V of the handle 30 in a first bearing 64 of the stopper member 43 and the second Orientation VI of the handle 30 stored in a second bearing 65 of the stop member 43, as in the FIGS. 11 to 14 shown.

Another end of the lever 42 is connected via a spring carriage 41 with the spring 40, in particular clipped. The lever 42 is in this case rotatably mounted in the spring carriage 41.

The spring 40 is mounted in a first spring retainer 82 at the first orientation V of the handle 30 as in FIGS FIGS. 11 and 12 shown. Accordingly, the spring 40 is mounted in a second spring retainer 83 in the second orientation of the handle 30, as in the Figures 13 and 14 shown.

By a diameter d of the spring 40, the thickness of the fitting body 2 is predetermined. Thus, the thickness corresponds to the spring retainer 82, 83 and the thickness of the aperture 9 of the thickness of the fitting body 2, as in FIG. 17 shown.

The spring receptacle 82, 83 further acts to guide the spring carriage 41. During compression or decompression of the spring 40, the lever 42 is guided via the spring carriage 41 on the spring receptacle 82, 83, wherein the spring carriage 41 slides along the spring receiver 82, 83. As a result, a movement of the lever 42 is predetermined.

The lever 41 is so connected to the spring 40 and the stopper member 43 that during movement from the operating position II to the rest position I, an angle HF between the spring 40 and the lever 41 and an angle HA between the lever 41 and the stopper member 43rd reduce so that the force acting on the handle 30 by the spring 40, the lever 41 and the stopper torque in the rest position I is greater than in the operating position II. In this way, the handle 30 can be particularly effectively held in rest position I. Further, this is overcompensated during the movement of the handle 30 from the operating position II in the rest position I decreasing spring force of the spring 40.

Preferably, the decreasing angles HF and HA are between 180 ° and 90 ° during a movement from the actuation position II to the rest position I. The angle HA is reduced to less than 90 ° during a movement from the actuation position II to the rest position I. This results in a wave-shaped torque curve for the torque acting on the handle 30 by the spring 40, the lever 41 and the stop element 43.

A first part 48 of the spring receivers 82, 83 formed in the carrier 10. In the assembled state of the fitting 1, the first part 48 of the spring receptacle 82, 83 is covered by the cover member 7, whereby the cover member 7 forms a second part 62 of the respective spring retainer 82, 83. The spring receivers 82, 83 are divided by a longitudinal division. As a result, the first part 48 of the spring receivers 82, 83 designed so open that the spring 40 can be easily mounted, disassembled or relocated from a spring retainer 82, 83 in the other spring retainer 82, 83.

The carrier has a first stop 46 and a second stop 47. The stops 46, 47 serve to limit a movement of the handle 30 in the mounted state. In the first orientation V of the handle 30, the stop member 43 is in the rest position I to the second stop 47 and in the operating position II on the first stop 46, as in the FIGS. 11 and 12 shown. In the second orientation VI of the handle 30, the stop member 43 is in the rest position I on the first stop 46 and in the operating position II on the second stop 47, as in the Figures 13 and 14 shown. Thus, the same stops 46, 47 limit the movement of the spring 40 in both the first and in the second orientation V, VI of the handle 30. The stops 46, 47 are symmetrical to a longitudinal plane LE of the fitting first

A stop angle AW is determined by the position of the stop element 43 in the rest position I at the first orientation V and by the position of the stop element 43 in the rest position I at the second orientation VI, as in FIG. 11 shown, given. The stop angle AW corresponds to the operating angle BW.

The handle 30 is reversibly releasably connected to the stop element 43. For this purpose, the mounting element 20 on the outer circumference of the mounting member 20 has a toothing, which engages in a toothing on an inner side 81 of the handle 30, as in the FIGS. 9 and 10 shown.

With respect to the carrier 10, the stop element 43 is arranged in the rest position I offset at the first orientation V by the stop angle AW relative to the rest position I in the second orientation VI. Due to the fact that the handle 30 rotates by 180 ° when changing from one orientation V, VI to the other orientation V, VI, an offset angle VW of 180 ° -AW results, with which the stop element 43 moves with respect to the handle 30 at a Change from the first orientation V to the second orientation VI is to be rearranged. For such an offset is possible, an angle between the teeth of the teeth ZW has been selected with an integer divisor of the offset angle VW, as in the FIGS. 9 and 10 shown. Here, the divider is exemplary 6.

Characterized in that the executed with the stop member 43 mounting element 20, the coupling element 24, this is at a first orientation V of the handle 30 relative to a second orientation VI of the handle 30 in the rest position I also offset by the stop angle AW, as can be seen by a comparison of the Figures 11 and 13 results. Accordingly, the counter-coupling element 25 is also offset by the stop angle AW in the first orientation V of the handle 30 relative to the second orientation VI of the handle 30, inserted into the carrier 10. The mating coupling receptacle 63 is configured in the carrier 10 by way of example such that the mating coupling element 25 is freely rotatable.

The transmission element 26 is reversibly detachably connected to the counter-coupling element 25. The transmission element 26 retains its alignment both in the first orientation V and in the second orientation VI of the handle 30 so that the transmission element 26 can be inserted into the nut of the lock. The counter-coupling element 25 can be inserted into the transmission element 26 in at least two positions, so that the Counter-coupling element 25 is rotatable when changing the orientation V, VI, the transmission element 26, however, retains its orientation. For this purpose, the counter-coupling element 25 is offset by the stop angle AW in the transmission element 26 can be used.

As in FIG. 18 shown, the counter-coupling element 25 and the transmission element 26 are interlocked. Here, an integer divider of the stop angle AW has been selected as the angle between two teeth of the teeth ÜZ. Here, the divider is exemplary 2.

The stopper member 43 is disposed between the rear side 112 of the carrier 10 and the second cover member 7. Thus, the stop member 43 is arranged inaccessible to an unauthorized user in an installed state of the fitting 1. Rather, the fitting 1 must first be dismantled from the building door before the stop element 43 is accessible. Characterized in that the stop member 43 limits movement of the handle 30 by abutment against the stops 46, 47 on the operating positions, the handle 30 can not be transferred to the mounting position III in the installed state of the fitting. Only when the fitting 1 is dismantled from the building door and the second cover 7 is released from the carrier 10, the stop member 43 is accessible.

The stopper member 43 is removed by pulling the installation member 20 out of the carrier 10. Thereafter, the handle 30 occupy the mounting position III.

In the mounting position III, the handle 30 is axially movable along the bearing element 11. Thus, the handle 30 can be disassembled from the fitting body 2. In the operating positions, however, the handle 30 is held on the bearing element 11 peel-off rotatably. Thus, disassembly of the handle 30 is prevented in the operating positions. For this purpose, the handle 30 has a first connecting element 39 and the bearing element 11 has a second connecting element 18. In the FIGS. 20 and 21 the connecting elements 18, 39 are shown, wherein in FIG. 21 a rest position I as an operating position and in FIG. 20 the mounting position III is shown.

The connecting elements 18, 39 are each designed as projections. As in FIG. 21 shown, in the operating positions, the first connecting element 39 is separated by the bearing sleeve 33 behind the second connecting element 18, so that the first connecting element 39 prevents by a positive connection with the second connecting element 18 that the handle 30 can be withdrawn from the bearing element 11.

In the mounting position III, however, the connecting element 18, 39 are offset without overlapping, as in FIG. 20 shown. As a result, a removal of the handle 30 is made possible.

The first connecting element 39 is formed on the inner side 81 of the handle 30, as in the FIGS. 20 to 22 shown. The second connecting element 18 is formed on the outside of the bearing element 11, as in the FIGS. 6 . 21 and 26 shown. Thus, the peel-resistant rotatable connection of the handle 30 with the bearing element 11 within the handle 30 takes place. Characterized in that the handle 30 rotatably connected both via the mounting member 20 with the coupling member 24 as well as on the bearing element 11 peelable rotatable within the handle 30, it is possible to dispense with externally visible grub screws in the region of the handle 30. The fact that the diaphragm 9 is fixed free of setscrews, it is possible to make the fitting 1 free of visible in the installed state grub screws.

A first end 80 of the handle 30 terminates in front of the carrier body 19, as in FIG FIG. 7 and 8th shown. The carrier 10 guides the handle 30 only via the bearing element 11.

In the region of the second connecting elements 18, a lateral surface 17 of the cylindrical bearing element 11 is configured without passage opening. Due to the continuous configuration of the bearing element 11, the bearing element 11 is sufficiently stable to absorb forces of the handle 30 can.

The first and the second connecting element 18, 39 are arranged one behind the other such that a 360 ° rotation of the handle 30 about the bearing element 11 is conceivable. The 360 ° rotation is undesirable because of the electrical conductors 37, 38, 91, 92. To prevent a 360 ° rotation, a rotation stop is provided. The rotation stop comprises a stop 66 of the bearing element 11 (s. FIG. 26 ) and a stop 67 of the handle 30, as in FIG. 22 shown. The stops 66, 67 are arranged behind the connecting elements 18, 39. The stops 66, 67 prevent a 360 ° rotation of the handle 30 in that the stops 66, 67 come into contact with each other during a rotation when the stop element 43 is disassembled.

The second connecting element 18 extends through the bearing sleeve 33. However, the bearing sleeve 33 covers a contact surface of the second connecting element 18, to which the first connecting element 39 adjoins. For easy mounting of the bearing sleeve 33 and to compensate for unevenness of the bearing element 11, the bearing sleeve 33 has a continuous slot 79, as in the Figures 9 and 20 shown.

The first and second connecting elements 18, 39 are each designed as two projections. The second connecting element 18 is designed symmetrically to the longitudinal plane LE of the fitting 1, as in the Figures 20 and 26 shown. As in FIG. 20 shown, cover the first and the second connecting element 18, 39 together in the mounting position III more than 75% of the circumference of the bearing element 11. Due to the large-scale configuration of the connecting elements 18, 39, a good guidance of the handle 30 can be achieved on the bearing element 11. The connecting elements 18, 39 are arranged such that both in the first orientation V and in the second orientation VI of the handle 30, the handle 30 is held in the operating positions peel-resistant rotatable.

The third diaphragm element 5 is arranged between the first and the second diaphragm element 3, 4. The third diaphragm element 5 serves as a light guide. For this purpose, it allows light from a plurality of light sources 52, which are designed as tricolor LEDs happen. The lighting means 52 are arranged on the printed circuit board 50, as in FIG FIG. 23 shown. Due to the different colors of the Illuminant 52 different states of the fitting 1 can be signaled. The different colors are used to display the user authorization, a state of charge of the energy storage and / or an operating condition of the fitting 1. The third panel member 5 is fixed by the handle 30 and the aperture elements 3, 4 on the fitting 1.

As in the FIGS. 7 and 8th shown, the drive 22 acts without an energy buffer, in particular without a spring, on the coupling element 24, whereby electrical energy is saved. As a result, long service life for the energy storage 57 can be achieved. In order to be able to check whether an engagement or disengagement process has led to the position X, XI of the coupling element 24 to be reached, the fitting 1 has a first sensor 53 and a second sensor 54. For the first sensor 53, a first light source 44 is provided, whose light beam can be received by the first sensor 53. For the second sensor 54, a second light source 45 is provided, whose light beam can be received by the second sensor 54. The first sensor 53 and the first light source 44 together form a first light barrier, which in the FIGS. 6 and 23 is shown. The second sensor 54 and the second light source 45 together form a second light barrier, which in the FIGS. 11 to 14 is shown.

The first and the second photoelectric sensors 53, 54, 44, 45 are arranged on the printed circuit board 50. The first light barrier 53, 44 and the second light barrier 54, 45 are formed on different sides of the printed circuit board 50. The printed circuit board 50 in this case acts as a light sheath between the light barriers 53, 54, 44, 45. The transmission of signals from the sensors 53, 54 also takes place on the printed circuit board 50.

The circuit board 50 has a bulge 75 for the arrangement of the light barriers 53, 54 44, 45 to the coupling element 24.

The sensors 53, 54 indicate the engaged and disengaged positions X, XI. As in FIG. 7 shown, in the engaged position X, the first sensor 53 can receive a light beam of the light source 44. In this case, the first sensor 53 transmits a signal which the control unit transmits as "1". In the engaged position X, the second sensor 54 can receive no light beam from the light source 45, since the coupling element 24 interrupts the light beam. The second sensor 54 transmits a signal which the control unit interprets as "0" to the control unit 56.

As in FIG. 8 shown, in the disengaged position XI, the first sensor 53 can receive no light beam from the light source 44, since the coupling element 24 interrupts the light beam. In this case, the first sensor 53 transmits a signal that the control unit interprets as "0" to the control unit 56. In the disengaged position XI, the second sensor 54 can receive a light beam from the light source 45. The second sensor 54 transmits a signal On the basis of the different signals of the first and second sensors 53, 54 for the two positions X, XI, the control unit 56 can detect in which of the two positions X, XI the coupling element 24 is located.

So that the light beam of the first light source 44 passes through the coupling element 24 in the engaged position X, the coupling element 24 has a light-permeable region 28 which is formed as a passage opening, as in FIGS FIGS. 6 to 8 shown. Also, the mounting member 20 has a light passage 70, as in Figs FIGS. 6 . 8th and 22 shown. The light passage 70 results from the fact that a guide part 71 of the mounting element 20 is interrupted as in FIG. 8 shown. The guide member 71 serves to engage in a circumferential groove of the counter-coupling element 25. As a result, the counter-coupling element 25 is aligned with the mounting element 20. In the light passage 70, a collimator 55 is inserted, as in the FIGS. 6 . 11 to 14 shown.

As in the FIGS. 11 to 14 is shown, the collimator 55, both in the rest position I and in the actuation position II, directs the light beam through the light passage 70. Also, the collimator 55 passes the light beam in the other operating positions through the light passage 70. Also, the collimator 55 passes the light beam the translucent area 28 in the engaged position X for all operating positions. Thus, the signal that is transmit the sensors 53, 54 to the control unit 56, regardless of the operating position of the handle 30th

In the engaged position X of the coupling element 24, the coupling element 24 is arranged at a distance from the transmission element 26 located behind the coupling element 24. In the disengaged position XI, the coupling element 24 is spaced apart from the drive 22 located in front of the coupling element 24. As a result, a locking of the coupling element 24 can be avoided.

The counter-coupling element 25 is designed to be open, so that the coupling element 24 can engage deeply in the counter-coupling element 25 without the counter-coupling element 25 abuts against the counter-coupling element 25 in the direction of movement.

Further, a toothing of the counter-coupling element 25 with the transmission element 26 is radially with respect to. The axis 120 is formed. The toothing of the counter-coupling element 25 is formed around the circumference of the counter-coupling element 25, which engages in a recess of the transmission element 26. In this way, a distance of the coupling element 24 in the engaged position X to the underlying transmission element 26 can be made large.

The control unit 56 stops the coupling element 24 as soon as the sensors 53, 54 transmit the signals indicative of the position X, XI to be reached. As a result, the coupling element 24 can move at a distance from the transmission element 26 and the drive 22.

So that the coupling element 24 reaches the engaged position X without stopping in the intermediate position XII, the counter-coupling element 25 can have a clearance relative to the coupling element 24, as in FIG FIG. 18 shown. This makes it possible that the coupling element 24 engages over a rotation angle range in the counter-coupling element 25. Thus, even if the user already starts to operate the handle 30, the engaged position X can still be achieved. For surface conditioning of the Clutch element 24 to the counter-coupling element 25, the opening 73 is made curved, as in FIG. 18 shown.

The coupling element 24 is in the disengaged position XI with a distance KG from the counter-coupling element 25, as in FIG. 6 shown. The distance KG is used as a measuring path of the second light barrier 54, 45. In this case, a light beam of the second light source 45 in the disengaged position XI reach the second sensor 54.

Furthermore, further structural measures to achieve the engaged position X are provided without stopping in the intermediate position XII.

Thus, by the guide means 71 and the groove 72, the counter-coupling element 25 is guided directly on the mounting element 20, so that alignment of the mounting element 20 and the counter-coupling element 25 is achieved to each other.

Further, the drive 22 and the spindle 23 move the coupling element 24 via a driver 29, as in the FIGS. 7 and 8th shown. Here, only the driver 29 has an internal thread for engagement in the spindle 23. The spindle 23 and the coupling element 24 have a play on each other, as in FIG. 20 shown. Likewise, the driver 29 is movably mounted in the coupling element 24 transversely to the direction of movement of the coupling element 24.

The counter-coupling element 25 and the transmission element 26 are designed separately from one another. The counter-coupling element 25 is axially fixed between the carrier 10 and the cover 7, as in the FIGS. 7 and 8th shown.

The transmission element 26 and the counter-coupling element 25 have a mutual play, as in FIG. 18 shown. The transmission element 26 is mounted axially and radially with respect to the axis 120 in the second cover element 7. Thus, it is possible for the transmission element 26 to adapt to the position of a lock without the counter-coupling element 25 varying in alignment with the coupling element 24. Here is a the Counter-coupling element 25 remote from the end of the transmission element 26 movable in several directions in space.

The transmission element 26 is widened at one end 89, whereby a position in the fitting body 2 and the cover 7 is possible. Next, the cover 7 has a circumferential collar 86 for storage, as in the FIGS. 6 . 16 and 19 shown. In particular, the collar 86 has a cylinder jacket-shaped portion 87 and an adjoining tapered portion 88. In the collar 86, the transmission element 26 is mounted like a ball joint. Due to the storage, the transmission element 26 with a in FIG. 17 shown maximum deflection angle LW are deflected from a vertical deflection. The maximum deflection angle LW can be taken in different directions in space, so that a straight circular cone, as in FIG. 19 shown, results.

For reliable and efficient power transmission, the counter-coupling element 25 and the transmission element 26 has a curved toothing, as in the FIGS. 18 and 19 you can see. For example, the toothing on the counter-coupling element 25 has eight teeth. So that the counter-coupling element 25 does not impair a bearing clearance for the bearing of the transmission element 26 by the cover element 7, the diameter of the elevation with the toothing of the counter-coupling element 25 is less than the diameter of the recess with toothing of the transmission element 26. Thus, the toothing of the counter-coupling element 25 only in sections in contact with the toothing of the transmission element 26. Due to the curved design of the toothing, the transmission element 26 and the counter-coupling element 25 are in a torque transmission yet flat against each other.

In the in the FIGS. 1 to 26 shown fitting 1, the fitting 1 door mounting receptacles 14, 15 only below the antenna 51. In this case, the first cover 6 may have a flat, continuous surface.

In the FIGS. 27 and 28 is a further embodiment of a fitting 1 according to the invention shown, in each case only a section is shown. Unless described below, the equivalent in the FIGS. 27 and 28 shown fitting in the FIGS. 1 to 26 described fitting 1. The in the FIGS. 27 and 28 shown fitting 1 has a door mounting receptacle 76 above the antenna 51. The door attachment receptacle 76 above the antenna 51 is configured as a hole group for variably placing a fastener 60. The door attachment receptacle 76 is formed electrically insulated from the carrier 10. For this purpose, insulation elements 77 are provided between the carrier 10 and the door attachment receptacle 76. The carrier 10 has a receptacle 16 configured as a passage opening for arranging the door attachment receptacle 76. At the edge of the receptacle 16 fastening means 61 are provided in the carrier 10, to which the door mounting receptacle 76 can be attached.

In addition to the gap 84, a further gap 85 is provided in the fitting 1 for the reduction of electrical currents. The gap 85 lies in the interior of the carrier 10, as in FIG FIG. 28 shown.

As in FIG. 27 shown, the first cover member 6 openings 78 for the passage of the fastener 60. In order to protect the printed circuit board 50 and the board 68, the openings 78 in the salable state are only pre-cut (not shown), so that when necessary to open a door to the opening 60 required for the fastener 60.
