Description

field of technology

[0001] The invention relates to a fitting that can be attached to a door or the like, according to claim 1. State of the art

[0002] GB 734 872 A discloses a generic fitting that can be attached to a door. A follower, rotatable by a rotary movement of a handle around a pivot axis, has two stops, each of which interacts with a fixed stop surface depending on the direction of rotation. A compression spring, mounted on a guide rod, engages one of the two stops. The guide rod has an eyelet at one end, which is pivotably attached to the stop via a tab extending laterally and to the rear. When changing the direction of rotation from left to right, the other end of the guide rod can optionally rest on one of two opposing support shoulders of the fitting's base body.

[0003] GB 1 123 025 A also discloses a fitting that can be attached to a door, wherein a spring engages one of three stops of the rotatable follower, the end of which facing away from the follower can be optionally attached to one of two opposing hooks of the base body when changing direction from left to right.

[0004] A door fitting in the form of a rosette is known from DE 203 17 239 U1. The rosette houses an electromechanical coupling. The coupling consists of an active coupling element connected to an inner spindle and featuring an electromechanical drive that allows a locking element to be moved between a coupling position and a release position. A passive coupling element, connected to an outer spindle, interacts with the active coupling element. In a coupling position, the locking element engages in a locking recess, thus coupling the two coupling elements. A rotary motion applied to the outer spindle is transmitted to the inner spindle, enabling a handle connected to the outer spindle to operate a door lock connected to the inner spindle. In the release position, the two coupling elements are rotatable relative to each other.

[0005] From GB 1, 182, 845 a door fitting is known in which a follower attached to a handle is acted upon by a power storage unit designed as a spring strut, which is supported with a foot on a support shoulder arranged centrally under the axis of rotation of the nut.

[0006] From DE 10 2015 109 916 A1, a door fitting is known in which a follower is actuated by a force storage device, which in turn is actuated by a compression spring located in a spring receptacle. The compression spring acts on a spring slide that is slidably guided in the spring receptacle. The spring slide and compression spring can be moved to a different spring receptacle for left / right switching.

[0007] DE 43 42 943 A1 describes a coupling between a push button and a square mandrel. An axially displaceable coupling sleeve allows the push button to be connected to the square mandrel in a rotary connection.

[0008] DE 11 2007 001 299 B1 describes a cam lock in which a rotary handle can be locked against rotation relative to a housing.

[0009] EP 3 460 149 B1 describes an electromechanical actuator with a shaft that can be rotated by a rotary drive and carries a thread which, depending on the direction of rotation of the shaft, can tension a spring in a first or the opposite second direction. The spring acts on an output element which, depending on the tension direction of the spring, can be spring-loaded or displaced in one direction or the other.

[0010] EP 0 566 447 A1 describes a fitting that can be attached to a door leaf, from the back of which fastening shafts protrude, which are stored in fastening slots of the fitting in order to assume different positions relative to a locking cylinder.

[0011] DE 1 794 936 U describes a fitting consisting of two fitting parts, wherein the two fitting parts can be connected with a screw engaging in a bayonet slot.

[0012] DE 203 17 239 U1 describes a door fitting for operating a lever handle, in which an outside lever handle spindle is connected to an inside lever handle spindle by a coupling consisting of two coupling elements that can be coupled together, so that a rotary movement can only be transmitted from a lever handle mounted on the outside lever handle spindle to a lock connected to the inside lever handle spindle if the two coupling elements are coupled together.

[0013] DE 77 17 581 describes the fastening of a door handle to a spindle, wherein a pressure piece is provided at the free end of the spindle, which interacts with the end of the spindle via an inclined surface. The pressure piece is actuated by a setscrew located in the shaft of the handle.

[0014] The state of the art also includes CN 207296631 U. Summary of the invention

[0015] The invention is based on the objective of further developing the generic door fitting in a way that is advantageous for use.

[0016] The problem is solved first by the invention specified in the claims, wherein the dependent claims represent not only advantageous further developments of the invention in the main claim, but also independent solutions to the problem.

[0017] It is proposed that in a fitting where the rotation angle of the driver is limited by a stop attached to the driver that interacts with fixed stop surfaces, and where at least one fixed stop arrangement is adjustable for left / right reversal of the fitting, the stop arrangement comprises two stop elements, one of which forms the stop surface interacting with the driver's stop. In particular, it may be provided that the stop elements are displaceable radially, with respect to the axis of rotation, between a storage position and an operating position. Furthermore, it may be provided that the stop elements are reciprocally movable from a storage position to an operating position.It may further be provided that the stop element in the active position secures the other stop element in its storage position. It may be provided that the stop elements are located in adjacent and, in particular, parallel bearing shafts. The bearing shafts are open, in particular, to a bearing cavity in which a driver is mounted, with which a rotary movement can be transmitted from a handle to a mortise lock. The driver may also have a coupling with which a rotary movement can be transmitted from a handle to a mortise lock. Furthermore, the driver may have a coupling with which an inner handle spindle can be selectively coupled to an outer handle spindle, so that in a release position in which the coupling elements are not coupled to each other, the handle can be actuated without engaging the inner handle spindle.It can be provided that each of the two stop bodies can be subjected to force in the direction of the axis of rotation by a spring element, which may be a helical compression spring. The stop bodies can be identical in design. To secure one of the stop bodies in the storage position, a locking pin can be provided. This locking pin can engage in a recess of the stop body to be held in the storage position. For this purpose, the locking pin can preferably move in a direction transverse to the direction of movement of the stop bodies. The stop body in its active position can have a head with a side surface against which the locking pin can bear when it is in the recess of the stop body held in the storage position. Each stop body can have such a head.Each stop body can also have a recess open to the other stop body for the entry of the locking bolt. A side surface of the head forms a support shoulder against which the locking bolt can rest when it engages in the recess of the other stop body. In the stored position, the spring element acting on the stop body is tensioned. In the operating position, a limit stop of the stop body can rest against a counter stop on a base plate of the fitting. The limit stop can be a laterally projecting projection of the stop body. The stop body can have a substantially rectangular cross-sectional profile. The stop body can have hinge symmetry, so that it has two opposing recesses that give the stop body a tapered shape. The two stop bodies are interchangeable due to their identical design.The head can have an end face with an optional recess, whereby the compression spring, which is supported at its other end at the end of the bearing shaft, can rest against the bottom of the optional recess. A force storage device is provided to hold the drive in the respective stop position.

[0018] According to the invention, the driver is held in a stop position by a force storage device, in which a push button connected to the driver assumes a neutral position, for example, a push button arm extending in a horizontal plane. The force storage device is designed as a spring strut. According to the invention, the force storage device is designed so that it can be reversed when the fitting is left / right reversible. The force storage device can consist of two shafts that are slidable relative to each other, one of which forms a foot that rests against a support shoulder of the base body. A spring can be mounted on the shaft, which exerts spring force on the two ends of the shaft in a direction away from each other. The end of the shaft opposite the foot can have a fastening means, in particular a fastening opening, through which a fastening pin projects, which is attached to the part of the driver that has the stop.It is specifically provided that the energy storage device, which acts on the driver in the stop position, is pivotally attached to the driver. The shaft of the energy storage device can run obliquely to the direction of extension of the fitting and, in particular, obliquely to a center line running in the direction of extension, i.e., from one narrow side of the fitting to the opposite narrow side. The shaft can cross the center line in its functional position. According to the invention, two opposing support shoulders are provided, against which the base of the energy storage device can selectively rest, i.e., either when the fitting is operated from the left or when it is operated from the right. Preferably, the base is held on the support shoulder solely by the clamping force of the energy storage device. A rear opening in the base body is provided, which can, in particular, be formed by a lock cylinder through-hole.This opening provides access to the base of the energy storage device or the spring strut formed by the energy storage device, and in particular, to the use of a tool. This allows the base to be lifted, for example with the blade of a screwdriver, and moved from its support position on the support shoulder. By pivoting and simultaneously rotating the drive mechanism, it can then be placed onto the opposite support shoulder. During this adjustment, the stop elements are simultaneously repositioned as described above. The stop elements can be spaced apart. The distance between the two stop elements can be slightly greater than the width of the drive mechanism's stop, measured in its direction of movement. This allows the tool to move the stop element in its effective position out of the drive mechanism's path of movement, thereby displacing the locking pin.Once the locking pin is no longer in front of the support shoulder of the first stop, the other stop body can move out of the way, allowing the other stop body to move from its storage position to its operating position. The locking pin then lies in front of the support shoulder of the stop body in its operating position. However, it can also be advantageous if the stop of the driver, in its storage position, is located under an end face of the stop body in its storage position that faces the axis of rotation. When the other stop body, in its operating position, is moved into its storage position, the locking pin is indeed released. However, the corresponding stop body cannot yet move into its operating position because the stop of the driver is in its path of movement.Only when, for example during the repositioning of the power storage unit, the driver is rotated further, can this stop body, freed from its restrained position, move into the operating position in order to shift the locking bolt, which then holds the stop body, formerly in the operating position, in the storage position.

Description of the embodiments 1. Base and cover plates

[0020] The Figure 1 , 2 , 7 and 27The drawings show the exterior of a fitting that can be attached to a door or the like. The fitting has a base plate 1, which is made of metal and can, for example, be manufactured as a metal injection-molded part. The base plate 1 has an elongated shape with a length several times greater than its width. The fitting has a thickness that is significantly less than its width. The back of the base plate 1 can be mounted onto a door leaf. The door leaf may contain a mortise lock (not shown in the drawings) that has a bolt operated by a cylinder and a cam that can be rotated by turning a lever handle 10. The cam is coupled to a latch, so that turning the lever handle 10 retracts the latch. For this purpose, the lever handle 10 is coupled to a spindle 67 that can protrude through the door leaf.In the exemplary embodiment, the coupling between the push-button spindle 67 and the push button 10 is effected via a coupling device consisting of two coupling elements 28, 39, which can be switched between a coupling position and a release position by means of an electric drive 45. This is achieved by means of an electric current supplied by a control unit (not shown) located in a housing 16. The housing 16 sits on an upper section of the base plate 1. The base plate 1 has a recess 17 at this point. A visible surface of the housing 16 transitions flush into a visible surface of a decorative plate 12, which extends over a substantial area of ​​the base plate 1 as a cover plate. The decorative plate 12 has an opening 13 through which the rotary movement of the push button 10 is transmitted and an opening 14 through which the locking cylinder passes.In the lower part of the base plate 1 are two battery compartments 18, which are closed by a battery compartment cover 19 that covers the narrow side of the base plate 1. Contacts 68 are provided, which are connected by cables (not shown) to an electronic circuit in the housing 16.

[0021] The base plate 1 forms a bearing cavity 2 in which a driver 28, 39 is mounted, which in this embodiment is formed by the two coupling elements 28, 39. The driver 28, 39 has two opposing sides, each forming a bearing collar 40, 48. The bearing collar 40 is mounted in the bearing bore 13 of the cover plate 12. The opposing bearing collar 48 is mounted in a bearing opening 21 of a rear cover plate 20. The two cover plates 12, 20 close the bearing cavity 2. The driver 28 has a bell-shaped form. It is fixedly connected to a push rod 49, onto which the push button 10 with its square opening 11 can be fitted. The driver 39, which is received in a cavity by the driver 28, has a square opening 57 into which a drive square 67 can be inserted to drive the mortise lock.The end of the drive square 67 that inserts into the square opening 57 has a transverse bore 81 in which a detent pin 82 is mounted. A compression spring is located between a rear end face of the detent pin 82 and the bottom of the transverse bore 81, which presses the detent pin 82 in one direction out of the transverse bore 81. The detent pin engages in a detent opening 83 of the square opening 57.

[0022] Adjoining the bearing cavity 2, in the direction of the lock cylinder passage opening 3, is a recess 79. This recess is also covered by the cover plate 20, so that a closed channel is formed between the bottom of the recess 79 and the cover plate 20, which opens into the lock cylinder passage opening 3. The opening of the channel formed by the recess 79 constitutes an access opening 78 through the rearwardly open lock cylinder passage opening 3 into the recess 79.

[0023] The one in Figure 26 The second embodiment shown differs from the one described in the Figures 1 to 25 The first embodiment shown is essentially distinguished by a longer cover plate 20. The cover plate 20 extends beyond the lock cylinder passage opening 3 and has an opening 93 through which the lock cylinder can pass. Parallel to the elongated opening 93, two mounting slots 86 extend for receiving a fastening element 25.

[0024] The in the Figures 27 to 30 The illustrated embodiment differs from the other embodiments in the length of the base body 1 and in the absence of a lock cylinder insertion opening.

[0025] The in the Figures 26 to 30The illustrated embodiments have a mounting frame 88 which, when installed, is arranged above the push button 10. An electronic circuit 89 is located in a cavity 90 of the mounting frame 88. The mounting frame 88 is covered by a cover cap forming a housing 16. 2. Left / right switch:

[0026] The driver 28, 39 forms a circumferential surface extending on a cylindrical surface, from which a stop 32 projects radially. The stop 32 interacts with stops 9, 9' formed by the base body 1. The stops 9, 9' are formed by steps in a circumferential wall of the bearing cavity 2.

[0027] A power storage device 34 is provided, which exerts a torque on the driver 28. The torque exerted by the power storage device acts on the stop 32 formed by the driver 28 against the stop 9, 9' formed by the base plate 1. In the exemplary embodiment, the power storage device 34 is designed as a spring strut. An elongated shaft 35 consists of two parts 35' and 35". which are slidable relative to each other. One free end of the energy storage device 35 forms a foot 38, which is supported on a support shoulder 6 of the base plate 1. The other end of the energy storage device 34 has a mounting opening 36 through which a mounting pin of a hook 33 extends. This hook is attached to the circumferential wall of the driver 28 in a position approximately diametrically opposite to the stop 32. If a center line is drawn through the axis of rotation of the handle 10 and the center of the lock cylinder passage opening 3, the energy storage device 34 crosses the center line at an angle.The support shoulder 6 is formed by the recess 79 in the area of ​​the access opening 78. Two identical support shoulders 6 are positioned opposite each other. The recess 79 is designed with a kind of hinge symmetry. The bearing cavity 2 transitions into the recess 79, forming an opening 77. The extension of the driver 28, which carries the hook 33, can pivot through the opening 77. The total pivot angle is 90 degrees. The recess 79 has a waist-like shape between the opening 77 and the access opening 78. In the area of ​​these waist-like shapes, the base plate has fastening openings 27 for the passage of threaded shanks 15, with which the cover plate 12 is attached to the base plate 1.

[0028] The shaft 35 carries a helical compression spring 37, which engages at one end at the base 38 and at the other end at a head forming the mounting opening 36, in order to compress the head away from the base 38. Starting from the point in the Figure 4 In the position shown, if a clockwise torque is applied to the push rod or the driver 28, the driver 28 can rotate about its axis of rotation A. This tensions the compression spring 37 and displaces the two parts 35' and 35" of the shaft 35 relative to each other. The driver 28 can be rotated until the stop 32 of the driver engages a stop surface 66 of a stop body 60'. The push rod 10 can then be moved in the position shown. Figure 4 The right-hand actuation position shown should be pivoted by approximately 45 degrees between two stop positions.

[0029] Approximately in the longitudinal center of the base plate 1 are two parallel bearing shafts 7. The bearing shafts 7 can also be positioned at an angle to each other. The bearing shafts 7 open into the bearing cavity 2. Each of the two bearing shafts 7 contains a stop element 60, 60'. The two stop elements 60, 60' are identical in design. The bearing element 60, 60' has a stop section 61, which is in a locking position that is in the Figure 4 is occupied by the stop body 60 shown on the left, lies within the storage shaft 7, so that the stop 32 can move freely past the storage body 60 in the storage position of the storage body 60.

[0030] The one in Figure 4The stop body 60' shown on the right assumes an active position. In the active position, the stop section 61 projects into the bearing cavity 2 such that a stop surface 66 formed by a side wall of the stop section 61 lies in the path of movement of the stop 32 of the driver 28.

[0031] The two stop bodies 60, 60' are each acted upon by a compression spring 64 in the direction of the opening of the bearing shaft 7. For this purpose, the compression spring 64 is supported against a wall of the bearing shaft 7 opposite the opening of the bearing shaft. The compression spring 64 acts upon a pressure surface 63 of the stop body 60, 60', which may be formed by a recess.

[0032] The two identically designed stop bodies 60, 60' are tapered between the pressure surface 63 and the stop section 61. They form recesses 62. However, only one recess 62 is required for the operation of each of the two stop bodies 60, 60'. The recess 62 has two outward-facing inclined surfaces 62', which form ramps with which a front face of a locking bolt 65 interacts.

[0033] The locking bolt 65 is mounted in a bore 8 that extends between the two bearing shafts 7. The length of the bore 8 is less than the length of the locking bolt 65 mounted therein. The end of the stop body 60, 60' pointing away from the stop section 61, which directly adjoins the pressure surface 63, forms a support shoulder 69. The two adjacent stop bodies 60, 60' form opposing support shoulders and opposing recesses 62, each of which interacts with one of the two opposing end faces of the locking bolt 65 in such a way that the locking bolt 65, which is supported on the support shoulder 69 of one stop body 60', engages with its other end face in the recess 62 of the other stop body 60 in order to hold the other stop body 60 in its holding position, whereas one stop body 60' holds the locking bolt 65 in this position with its support shoulder 69.

[0034] The storage chambers 7 are covered by the cover plate 12. However, they are accessible from the rear of the base plate 1. For this purpose, there are actuating openings 80 on the rear side, which open into the bottoms of the storage chambers 7. A tool, for example the blade of a screwdriver, can be inserted into the actuating openings 80 to move the stop body 60, 60' in its operating position. Figure 4 In the illustrated operating position, this is the right-hand stop body 60'. If the stop body 60' is displaced against the restoring force of the spring 64, the locking bolt 65 can move into its bearing bore 8. This occurs by means of the force exerted by the compression spring 64, which acts on the stop body 60, and the effect of the inclined surface 62'. The displacement of the stop body 60' thus leads to a spring-induced displacement of the other stop body 60 into its operating position.

[0035] Again Figure 9 As can be seen, the stop body 60, 60' has laterally projecting limit stops 70, which prevent the stop body 60, 60' from leaving the storage shaft 7 in the operating position. In the operating position, the limit stops 70 rest against counter stops (not shown).

[0036] To the in the Figure 4To move the fitting shown in the right-hand actuation position to a left-hand actuation position, the energy storage device, i.e., the spring strut 34, must be moved out of its operating position. This is done using a tool, for example, the blade of a screwdriver, which is inserted through the access opening 78 and used to lift the foot 38 from the support shoulder 6, so that the energy storage device 34 can assume the position shown in Figure 5. In this position, the stop 32 lies in front of the stop surface 66 of the stop body 60', which is in its operating position. If the stop body 60' is now lifted from its operating position to its storage position using a tool through the actuation opening 80, the other stop body 60 moves into the position shown in the Figure 6The depicted operating position. In this position, the locking bolt 65 moves from left to right and engages in the recess 62 of the stop body 60' to hold it in the locked position. The locking bolt 65 then bears against the support shoulder 69 of the stop body 60, which is now in the operating position.

[0037] Using a tool, for example the blade of a screwdriver, the power storage unit 34 can then be inserted into the Figure 6 The lever is brought into the position shown, in which the foot 38 rests on a support shoulder 6. Here, too, the spring strut 34 crosses a center line of the fitting obliquely. In this left-hand actuation position, the lever can be rotated by 45 degrees with a stop limit, whereby the stop 32 of the energy storage device 34 is acted against the stop 9' of the base plate 1 and can be brought against the stop surface 66 of the stop body 60 by rotating the lever 10.

[0038] It is considered advantageous that the left / right conversion is possible without the prior removal of covering materials, for which purpose openings are provided in the back of the fitting through which a tool or the like can be used to convert the stop bodies 60, 60' or to release the energy storage device 34 from a first functional position in order to then bring it into a second functional position. 3. Coupling between outer pusher pin and inner pusher pin

[0039] The fitting has a coupling formed by the drivers 28, 39 to selectively engage the external handle 10, which is mounted on an external handle spindle 49, with a mortise lock in either a rotary-locked position or a release position. In the rotary-locked position, the external handle spindle 49 is rotationally fixed to the drive square 67. In the release position, this rotational fixity is released. The external handle spindle 49 can be rotated without engaging the drive square 67. The driver 28, which forms a passive coupling element of the coupling, has a substantially rotationally symmetrical shape. The driver 28 is fixedly connected to the handle spindle 49, in this exemplary embodiment as a single material. The handle spindle 49 protrudes from an end face of the bearing collar 40, with which the driver 28 is mounted in the bearing bore 13 of the cover plate 12.The bearing collar 40 originates from a broad side surface of a cylindrical section formed by the outer surface of a cavity wall 30. From this outer wall extend the stop 32 and the diametrically opposite extension, which forms the fastening means 33 for the energy storage device 34. The cavity wall 30 surrounds a coupling cavity 29 with a substantially flat bottom and an inner surface of the cavity wall 30 extending onto an inner cylindrical surface. The cavity wall 30 has at least one restraint recess 31 in the form of a radial opening through the cavity wall 30. In the exemplary embodiment, two such radial openings are provided, each forming a restraint recess 31 and offset from each other by 90 degrees.In the center of the bottom of the coupling cavity 29 is the end of an axial bore 51, which extends through the entire push rod 49 and in which a clamping screw 56 is inserted, the head of which rests on the edge of the opening of the axial bore 51.

[0040] The driver 39 forms the other, active coupling element, which interacts with the coupling element 28. The driver 39 forms a housing with a housing cavity in which a restraint element 41 is arranged. The restraint element 41 is located in the Figure 12 shown in a retracted position. This corresponds to the release position of the clutch. With a drive motor 45, which rotates a drive shaft 46, the restraint element 41, which is a slide, can be moved from the release position to a rotational engagement position. In the rotational engagement position, which is shown in the Figure 13As shown, an end section of the restraint element 41 engages in the restraint recess 31 of the cavity wall 30. The restraint element 41 is slidably mounted in a bearing shaft 44 for this purpose. The restraint element 41 has a substantially square cross-section. The bearing shaft 44 also has a square internal cross-section, so that the restraint element 41 is mounted and guided non-rotatably in the bearing shaft 44.

[0041] The restraint element 41 has a cavity that is open to one of its polygonal sides. A U-shaped bearing body 43 is inserted into the opening of the cavity. A compression spring 42 extends between the two legs of the U-shape of the bearing body 43. The shaft 46, which can be driven by the drive motor 45, extends through the compression spring 42. A threaded element 47 is mounted on the shaft 46 and engages in the spaces between the helical compression spring 42. When the drive motor 45 is rotated, the compression spring 42 is compressed, depending on the direction of rotation of the drive motor 45, either against one of the two legs of the U or the other, so that a force is exerted on the restraint element 41 either in the direction of the restraint recess 31 or away from the restraint recess 31.

[0042] Starting from the in Figure 12In the depicted release position, when the shaft 46 is rotated such that the compression spring 42 is displaced to the left, the restraint element 41 is acted upon in the direction of the restraint recess 31, so that it engages the Figure 13 The illustrated subsequent position can be assumed, in which the restraint element 41 engages in the restraint recess 31 and thus couples the two coupling members 28, 39 together in a rotationally fixed manner. This corresponds to the coupling position of the coupling.

[0043] Starting from the one in the Figure 13 In the depicted rotary drive position, the shaft 46 is rotated in the opposite direction, so that the compression spring is displaced to the right, the restraint element 41 is displaced towards the out of the restraint recess 31, so that the Figure 12The release position shown is reached. The drive motor 45 does not need to run against an end stop in either direction. If the spring 42 is moved completely to the left or completely to the right, the threaded element 47, which may be a single thread, emerges from the helix formed by the spring element and can rotate freely.

[0044] The Figure 14Figure 12 shows an operating position, essentially corresponding to Figure 12, except that the coupling member 39, which is mounted on the inner pusher pin formed by the drive square 67, is rotated relative to the coupling member 28 such that the restraint element 41 is not aligned with the restraint recess 31. When the drive motor 45 is actuated in this rotational position, the spring element 42 tensions and moves the restraint element 41 towards the cavity wall 30 until it abuts the inside of the cavity wall 30. In this state, the coupling member 28, which is connected to the outer pusher pin 49, can be rotated until the restraint recess 31 is aligned with the restraint element 41, which is then moved into the restraint recess 31 by the force of the relaxing spring 42.

[0045] The Figure 15Figure 1 shows that the axial length of the coupling element 28 extends essentially over the entire depth of the bearing cavity 2. The end face 40' surrounding the bearing collar 40 rests against the broad side of the cover plate 12 facing the base body 1. The edge 30' rests against the broad side of the cover plate 20 facing the base body 1. The two cover plates 12 and 20 thus form bearing surfaces for the driver and the coupling element 28, respectively, with their broad sides. The active coupling element 39, which carries the drive motor 45 that rotates along with the coupling element 39, is fully enclosed in the coupling cavity 29. Cables (not shown) are provided to connect the drive motor 45 to the electronic control unit located in the housing 16.The coupling element 28 is mounted in the bearing cavity in such a way that the circumferential surface of the cavity wall 30, which points radially outwards with respect to the axis of rotation A, has a free distance to a wall 2' that bounds the bearing cavity 2.

[0046] The coupling element 39 forms an end face 48' adjoining the bearing collar 48, which rests against the broad side surface of the cover plate 20.

[0047] The cover plate 20 has an arc-shaped slot 59 extending around the bearing bore 21, which spans an angle of 90°. A stop pin 58 of the driver 39 engages in this arc-shaped slot 59. It is therefore specifically designed that the active driver 39 can only rotate through a limited angle, and in particular through an angle of 90 degrees. 4. Fasteners for attaching the fitting to a door leaf

[0048] Another aspect of the invention relates to mounting slots 4, 5, and 86 arranged in the base plate 1, which are designed to receive mounting elements 25 and 26. The mounting slots 4, 5, and 86 extend parallel to the direction of extension of the elongated base plate 1. The mounting slots 4, 5, and 86 have a first, longer section in which the mounting element 25 can be moved in the plane of extension of the base plate 1 in a direction toward or away from the handle spindle 49 or 67. This allows, on the one hand, the distance of the mounting element 25 to the handle spindle 49 or 67, and on the other hand, the distance between the two mounting elements 25 can be changed. This enables the fitting to be adapted to regionally varying distances between the axis of the handle and the axis of the lock cylinder.

[0049] The mounting slot 4, 5, 86 has an end section 4', 5' or 86' that is wider than the longer section of the mounting slot 4, 5, 86. A mounting element 25, 26 can be inserted into the mounting slot 4, 5, 86 from the rear of the base plate 1 through this end section 4', 5', 86'. This is achieved by moving the mounting element 25, 26 in a direction perpendicular to the plane of extension of the base plate 1.

[0050] The Figures 17 to 20Figure 1 shows cross-sections through the various mounting slots 4, 5, and through an end section 5'. Mounting slots 4, 5, and 86 have a narrow section. This section extends from the rear of the base plate 1 into a wider section 75, 76, which runs along the front face of the base plate 1 facing away from the rear. In this area, the base plate 1 is covered by the cover plate 12. Mounting slot 5 thus forms an undercut, T-shaped, elongated opening, the bottom of which is formed by the cover plate 12. In end sections 4', 5', and 86', the mounting slot is not undercut. In these end sections 4', 5', and 86', the mounting slot has a width corresponding to the width of the widened section 75, 76.

[0051] The Figure 18Figure 1 shows a first fastening element 25, which is inserted into a fastening slot 5. Since the fastening slots 4 and 5 are essentially identical in design, the following can be seen in the Figure 19 The fastening element 25 shown in the fastening slot 5 may also be arranged in the fastening slot 4. The fastening element 25 has a disc-shaped head 25', the width or diameter of which is slightly smaller than the width of the widened section 75. A shaft adjoins the head 25', which has at least two axial sections. A first axial section of the shaft 25' forms a neck 25" which has a diameter that is smaller than the diameter of the head 25' and smaller than the width of the fastening slot 5. This neck 25" extends within the base plate 1.

[0052] A second section of the shaft 25' extends from the neck 25", projecting outwards from the base plate 1 and through the door leaf to which the fitting can be attached. The end of the shaft 25' opposite the head 25' has a threaded opening into which a fastening screw can be inserted.

[0053] To mount the fastener 25, the head is inserted through the end section 4', 5', or 86' from the rear of the base plate 1. It is inserted until the end face of the head 25' abuts the cover plate 12. When the fastener 25 is inserted into the mounting slot 4, it is inserted until the head abuts the housing 16, which covers the mounting slot 4 or the widened section 75. From this position, the fastener 25 can be moved within the mounting slot 4, 5 to the position suitable for fastening. The reference numeral 85 designates a ring located in the transition area between the neck 25" and the section of the shaft 25' projecting from the base plate 1.

[0054] The mounting slot 5 opens into a cylinder pass-through opening 3. The end section 5' of this mounting slot 5 is formed by a narrowed section of the cylinder pass-through opening 3, in which a flange section of a cylinder can be received. If this end section 5' is used to receive a flange section of a cylinder, the cover plate 12 has a cylinder pass-through opening 14 that is a correspondingly large distance from the handle spindle 49. With this type of use of the fitting on a lock with a large distance, no fastening element can be positioned there.

[0055] In a fitting configuration on a lock with a smaller distance dimension, where the distance between the handle spindle 49 and the axis of the lock cylinder is smaller, a fastening element 26 can be inserted into the end section 5', as shown in the Figure 20The cover plate 12 used here has a cylinder pass-through opening 14, which is located closer to the handle spindle 49, so that the end section 5' is covered by the cover plate 12. The end section 5' has a widened section 76, which runs directly below the cover plate 12 and whose width is greater than the width of the end section 5'. The fastening element 26 has a head 26' whose diameter is larger than the head 25' of the fastening element 25. The head 26' is inserted into the widened section 76 from a wider section of the cylinder pass-through opening 3. A neck 26‴ adjoining the head 26' is inserted precisely into the end section 5'. The neck 26‴ has a diameter that is larger than the width of the fastening slot 5 and approximately corresponds to the diameter of the head 25'.The neck 26‴ is followed by a shaft section of the shaft 26‴, which can protrude through the door leaf and which can have a threaded bore 74.

[0056] The in the Figures 23 to 25 The second embodiment shown depicts a wide escutcheon in which a mounting slot 86 is arranged next to each of the cylinder pass-through openings 3. The two mounting slots 86, which run parallel to each other and parallel to the cylinder pass-through opening 3, each have an end section 86' and otherwise a shape similar to that of the mounting slots 4 and 5, so reference is made to the corresponding descriptions. The distance between the two mounting slots 86 corresponds to the standardized distance between the mounting screws of a cylinder rosette.

[0057] In the Figure 26In the illustrated embodiment, the mounting slots 86 run parallel to an elongated opening 93 for the passage of a lock cylinder. The mounting slots 86 are associated with the cover plate 20, which can be connected to the back of the base plate 1. A further mounting slot 4 runs centrally between the two longitudinal edges of the cover plate 20. The bearing bore 21 is located between the mounting slot 4 and the two mounting slots 86. 5. Attaching the cover plate 12 to the base plate using threaded shafts

[0058] The Figures 17 and 18The threaded shanks 15, attached to the cover plate 12 on the side opposite the visible side, each protrude from a head 15' that is connected to the back of the cover plate 12. The heads 15' can be welded or soldered to the back of the metal cover plate 12. Alternatively, they can be bonded to the cover plate 12. This can be particularly advantageous if the cover plate 12 is made of plastic. It is also possible for the threaded shanks 15 to be formed from the same material as the cover plate 12. Preferably, the threaded shanks 15 are made of metal and are bonded to the cover plate 12 in such a way that the front surface of the cover plate 12, which forms a decorative surface, is not visually affected by the fastening.

[0059] The length of the threaded shanks 15 is slightly less than the thickness of the base plate 1. The base plate 1 has a mounting opening 27 for each threaded shank 15, extending through the entire base plate 1. On its side facing the cover plate 12, the mounting opening 27 has a widening 27' to receive the head 15'. On its side facing the rear of the base plate 1, the mounting opening 27 also has a widening 27", which serves to receive a nut 84 that can be screwed onto the thread of the threaded shank 5. When tightened, the end face of the nut 84 lies within the widening 27". The end face of the nut 84 has recesses or a profile against which a screwdriving tool can engage.

[0060] The fastening openings 22, 27 can in particular have sections that are arranged one behind the other in the axial direction and that have different diameters.

[0061] The Figure 18 It can be seen that the threaded shaft 15 not only extends through the mounting opening 27 of the base plate 1, but also through a mounting opening 22 of the cover plate 20, which is recessed into a depression on the back of the base plate 1. The mounting opening 22 may have a countersink against which the countersunk head of the nut 84 can bear.

[0062] In particular, an even number of threaded shanks 15 are provided. The number of threaded shanks 15 with which the cover plate 20 is attached to the cover plate 12 can also be even and preferably four, six or eight. 6. Attaching the handle to the spindle

[0063] The Figures 8 , 11 , 15 and 21Figure 1 shows a driver 28, which has a bell-shaped form. The driver 28 has a circular end face with a bearing collar 40, which is supported in a bearing bore 13 in the cover plate 12. The driver 28, or rather its end face, or the end face 40' of the bearing collar 40, is formed by the square push-button spindle 49, which is made of a single material. The push-button spindle 49 has a bore 51 that extends in the axial direction of the push-button spindle 49. The bore 51 has a countersink located in the center of the bottom of the coupling cavity 29 and extends to the free end of the push-button spindle 49. The bore 51 is offset from the central axis of the push-button spindle 49, so that it penetrates an inclined surface 50 at the free end of the push-button spindle 49.

[0064] The inclined surface 50 begins at a step located away from the free end of the spindle 49 and continues, decreasing the cross-sectional area of ​​the spindle 49, until it reaches the free end of the spindle 49. There, it terminates at a reduced-section end face of the spindle 49.

[0065] A clamping element 52 in the form of a wedge is provided, which has a wedge surface 54 that rests on the inclined surface 50. The clamping element 52 has a threaded bore 55 into which the external thread of a clamping screw 56 is screwed, the clamping screw extending into the bore 51. The countersunk head of the clamping screw 56 lies in the recess of the bottom of the coupling cavity 29.

[0066] The angle of inclination of the wedge surface 54 corresponds to the angle of inclination of the inclined surface 50, such that a pressure surface 53 opposite the wedge surface 54 runs parallel to a polygonal surface of the push-button spindle 49 opposite the inclined surface 50. By turning the clamping screw 56, the wedge-shaped clamping element 52 can slide along the inclined surface 50 with its wedge surface 54, thereby changing the distance between the pressure surface 53 and the polygonal surface of the push-button spindle 49 opposite it.

[0067] The actuator 10 can be connected to the actuator spindle 49 as follows. The cover plate 12 is not attached to the base plate 1. The actuator spindle 49 is inserted through the bearing bore 13 of the cover plate 12 until the ring collar 40 is located in the bearing bore 13. The actuator spindle 49 is then inserted into the polygonal opening 11, which is preferably a square opening, until the end face of the actuator 10, into which the square opening 11 opens, rests against the end face 40' of the bearing collar. A radially outer area of ​​the end face of the actuator 10 projects radially beyond the bearing collar 40. The clamping screw 56 is then turned until the clamping element 52 assumes a clamping position in which the pressure surface 53 exerts force on the inner wall of the square opening 11.

[0068] Following this, the cover plate 12 can be attached to the base plate 1 by means of the threaded shafts 15 and the nuts 84 screwed onto them.

[0069] In the Figures 26 to 20 In the illustrated embodiments, the push button 10 is directly connected to the coupling element 28. The coupling element 28 carries a square extension 87, which is formed from the same material as the coupling element 28. The square extension 87 can be inserted into the square recess of the push button 10. A fastening screw holds the push button 10 to the square extension 87.
