State of the art

From the DE 203 17 239 U1 a door fitting in the form of a rosette is already known. The rosette stores an electromechanical clutch. The clutch consists of an active clutch member which is connected to an inner mandrel and has an electromechanical drive with which a restraining element can be moved between a clutch position and a release position can be relocated. A passive coupling element, which is connected to an outer handle mandrel, interacts with the active coupling element. In a coupling position, the restraining element engages in a restraining recess, so that the two coupling members are coupled to one another.

Summary of the Invention

The invention is based on the object of further developing a door fitting that supports a driver with which a handle can transmit a rotational movement to a mortise lock inserted in the door leaf in a way that is advantageous in terms of use.

The object is initially achieved by the invention specified in the claims, with the subclaims not only advantageous developments of those specified in the main claim or subclaims Invention, but also represent independent solutions to the task. The object is also achieved by one of the technical features specified below, which can be realized in combination with each of the claims.

A variant of the invention proposes that, in the case of a fitting, in which the angle of rotation by which the driver can be rotated, is limited by means of a stop attached to the driver that interacts with stop surfaces fixed to the housing, and at least one stop arrangement fixed to the housing for left/right switching of the fitting can be changed, with the stop arrangement forming two stop bodies, of which either one stop body or the other stop body forms the stop surface that interacts with the stop of the driver. It can be provided, in particular, that the stop bodies can be displaced in the radial direction, relative to the axis of rotation, between a storage position and an active position. Furthermore, it can be provided that the stop bodies can be brought alternately from a storage position into an operative position. It can also be provided that the stop body assuming the active position restrains the respective other stop body in its storage position. Provision can be made for the stop bodies to lie in storage shafts arranged next to one another and in particular parallel next to one another. The storage shafts are open in particular to a storage cavity in which a driver is mounted, with which a rotary movement can be transmitted from a handle to a mortise lock, the driver also having a coupling with which an inside handle mandrel can be selectively coupled with an outside handle mandrel , so that in a release position in which the coupling members of the coupling are not coupled to one another, the handle can be actuated without entrainment of the inside handle mandrel. It can be provided that the two stop bodies in the direction of the axis of rotation by a spring element which can be a helical compression spring, force can be applied. The stop bodies can be of the same design as one another. A locking pin can be provided in order to tie up one of the stop bodies in the storage position. 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 shift in a direction transverse to the direction of displacement of the stop body. The stop body that assumes an active position can have a head that has a side surface on which the locking pin can be supported when it rests in the recess of the stop body that is 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 pin. A side face of the head forms a support shoulder on which the locking pin can be supported when it engages in the recess of the other stop body. In the storage position, the spring element acting on the stop body is tensioned. In the operative position, a limit stop of the stop body can be supported on a counter-stop of a base plate of the fitting. The limit stop can be a laterally protruding projection of the stop body. The stop body can have a substantially rectangular cross-sectional profile. The stop body can have a folding 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 depression, in which case the compression spring, which is supported with its other end at the end of the storage slot, can be supported on the bottom of the optional depression. An energy accumulator is provided to hold the driver in the respective stop position.

The invention also relates to a development of a fitting, in particular a fitting characterized above, in which the driver is held by an energy store in a stop position in which a handle connected to the driver assumes a neutral position, for example a handle arm extends in a horizontal plane. According to this inventive development of the prior art and the previously characterized fitting, the force accumulator is designed as a spring strut. Alternatively or in combination with this, the energy store can also be designed in such a way that it can be moved if the fitting can be switched to the left/right. The force accumulator can consist of two shafts that can be moved relative to one another, one of which forms a foot that is supported on a supporting shoulder of the base body. A spring can be seated on the shank which applies spring force to the two ends of the shank in a direction away from one another. The end of the shaft opposite the foot can have a fastening means, in particular a fastening opening, through which a fastening pin protrudes, which is fastened to the part of the driver which has the stop. In particular, it is provided that the energy accumulator, which acts on the driver in the stop position, is attached to the driver in an articulated manner. The shaft of the force accumulator can run obliquely to the extension direction of the fitting and in particular obliquely to a center line which runs in the extension direction, ie from one narrow side of the fitting to the opposite narrow side. The shaft can cross the midline in its functional position. In particular, two opposing support shoulders are provided, on which the foot of the force accumulator can optionally be supported, ie either when the fitting can be actuated to the left or when the fitting can be actuated to the right. The foot is preferably held on the support shoulder solely by the clamping force of the force accumulator. A rear opening of the base body can be provided, which can in particular be formed by a lock cylinder passage opening. Through this opening is the foot of the force accumulator respectively of the spring strut formed by the energy accumulator and in particular accessible with a tool, so that the foot can be lifted, for example with the blade of a screwdriver, and brought out of its supporting position on the supporting shoulder in order to be placed on the opposite supporting shoulder by pivoting and simultaneously rotating the driver to be able to During this changeover, the stop bodies are changed over at the same time in the manner described above. The stop bodies can be spaced apart from one another. The distance between the two stop bodies can be slightly larger than the width of the driver's stop measured in its direction of movement, so that the stop body in its active position is brought out of the movement path of the driver's stop with the tool, whereby the locking pin can shift. After the locking pin is no longer in front of the support shoulder of one stop body, the other stop body can then give way so that the other stop body moves from its storage position into the active position. The locking pin is then located in front of the support shoulder of the stop body assuming the operative position. However, it can also prove to be advantageous if the stop of the driver in the stop position is located under an end face of the stop body which is in the storage position and points towards the axis of rotation. If the other stop body, which is taking up its operative position, is stored in the storage position, the locking pin is released. However, the associated stop body cannot initially move into its active position, since the stop of the driver is in its path of movement. Only when, for example in the course of changing the energy store, the driver is turned further can this stop body, freed from its restraining position, move into the operative position in order to move the locking pin, which then holds the stop body, which was previously in the operative position, in the storage position.

Description of the embodiments 1. Base and cover plates

the figures 1 , 2 , 7 and 27 show the exterior of a fitting which can be fastened to a door or the like. The fitting has a base plate 1, which consists of metal and can be manufactured, for example, as a metal injection molded part. The base plate 1 has an elongated shape with a length that is several times greater than its width. The fitting has a thickness that is significantly less than the width. The back of the base plate 1 can be mounted on a door leaf. A mortise lock (not shown in the drawings) can be located in the door leaf, which has a bolt that can be actuated by a lock cylinder and a nut that can be rotated by actuating a handle 10, which is coupled to a latch so that the latch can be retracted by turning the handle 10 . For this purpose, the printer 10 is coupled to a handle mandrel 67 which can protrude through the door leaf. In the exemplary embodiment, the coupling between the handle mandrel 67 and the handle 10 takes place via a coupling device which consists of two coupling members 28, 39 which can be switched between a coupling position and a release position by means of an electric drive 45. This takes place via electric current, which is provided by a control device (not shown) that is located in a housing 16 . The housing 16 sits on an upper section of the base plate 1. The base plate 1 has a depression 17 there. A visible surface of the housing 16 merges flush into a visible surface of a decorative plate 12, which as a cover plate extends over a significant area of the base plate 1. In the decorative plate 12 there is an opening 13 through which the rotational movement of the handle 10 is transmitted and an opening 14 through which the lock cylinder extends. In the area below The base plate 1 has two battery compartments 18 which are closed by a battery compartment cover 19 covering the narrow side of the base plate 1 . Contacts 68 are provided which are connected to an electronic circuit in the housing 16 by cables (not shown).

The base plate 1 forms a bearing cavity 2 in which a driver 28, 39 is mounted, which is formed by the two coupling members 28, 39 in the exemplary embodiment. The driver 28, 39 has two sides pointing away from one another, each of which forms a bearing collar 40, 48. The bearing collar 40 is mounted in the bearing bore 13 of the cover plate 12. The bearing collar 48 pointing away from it 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 shape. It is firmly connected to a handle mandrel 49 onto which the handle 10 with its square opening 11 can be attached. The driver 39 received by the driver 28 in a cavity has a square opening 57 into which a square drive 67 can be inserted to drive the mortise lock. The end of the drive square 67 which is inserted in the square opening 57 has a transverse bore 81 in which a locking pin 82 is mounted. A compression spring is located between a rear end face of the locking pin 82 and the bottom of the transverse bore 81 and acts on the locking pin 82 in a direction out of the transverse bore 81 . The latching pin engages in a latching opening 83 of the square opening 57 .

A recess 79 adjoins the bearing cavity 2 in the direction of the opening 3 in the lock cylinder. 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 passage opening 3 in the lock cylinder. The mouth of the channel formed by the recess 79 forms an access opening 78 through the opening 3 in the lock cylinder, which is open at the rear, into the recess 79.

That in the figure 26 illustrated second embodiment differs from that in FIGS Figures 1 to 25 illustrated first embodiment essentially 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 reach. Two fastening slots 86 for receiving a fastening element 25 extend parallel next to the elongated opening 93.

That in the Figures 27 to 30 The illustrated embodiment differs from the other embodiments by the length of the base body 1 and by the lack of a lock cylinder insertion opening.

The in the Figures 26 to 30 illustrated embodiments have a holding frame 88 which is arranged above the handle 10 in the installed state. An electronic circuit 89 is located in a cavity 90 of the holding frame 88. The holding frame 88 is covered with a covering cap forming a housing 16. FIG.

2. Left/right conversion:

The driver 28, 39 forms a peripheral surface running on a cylinder jacket surface, from which a stop 32 protrudes in the radial direction. The stop 32 interacts with stops 9, 9 ', which are formed by the base body 1. The stops 9, 9 'are formed in a peripheral wall of the bearing cavity 2 of steps.

An energy accumulator 34 is provided, which exerts a torque on the driver 28 . The torque exerted by the force accumulator 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 energy accumulator 34 is designed as a spring strut. An elongated shaft 35 consists of two mutually displaceable parts 35 'and 35'. A free end of the force accumulator 35 forms a foot 38 which is supported on a support shoulder 6 of the base plate 1. The other end of the force accumulator 34 has a fastening opening 36 through which a fastening pin of a hook 33 which is fastened approximately diametrically opposite the stop 32 on the peripheral wall of the driver 28 extends. If a center line is drawn through the axis of rotation of the handle 10 and the center of the opening 3 in the lock cylinder, the energy store 34 crosses the center line in an inclined position. The support shoulder 6 is formed by the recess 79 in the area of the access opening 78 . There are two identically designed support shoulders 6 opposite. The recess 79 is designed to a certain extent with folding symmetry. The bearing cavity 2 transitions into the recess 79 with the formation of an opening 77 . The extension of the driver 28 carrying the hook 33 can pivot through the opening 77 . The total pan angle is 90 degrees. Between the opening 77 and the access opening 78, the recess 79 has a waist. In the area of these waists, the base plate has fastening openings 27 for the passage of threaded shafts 15, with which the cover plate 12 is fastened to the base plate 1.

The shaft 35 carries a helical compression spring 37 which engages the base 38 at one end and a head forming the mounting aperture 36 at the other end to bias the head away from the base 38 . Is starting from the in the figure 4 If a clockwise torque is applied to the handle mandrel or the driver 28 shown in the position shown, the driver 28 can rotate about its axis of rotation A rotate. The compression spring 37 is tensioned and the two parts 35' and 35" of the shaft 35 move against each other. The driver 28 can be rotated until the stop 32 of the driver strikes a stop surface 66 of a stop body 60'. The pusher 10 can be in the in the figure 4 Pivot the right-hand actuation position shown by about 45 degrees between two stop positions.

Approximately in the longitudinal center of the base plate 1 there are two storage slots 7 aligned parallel to one another. However, the storage slots 7 can also be at an angle to one another. The bearing shafts 7 open into the bearing cavity 2. In each of the two bearing shafts 7 there is a stop body 60, 60'. The two stop bodies 60, 60' have the same design as each other. The bearing body 60, 60 'has a stop portion 61 in a storage position in the figure 4 is occupied by the stop body 60 shown there on the left, is within the storage shaft 7, so that the stop 32 can move freely past the bearing body 60 when the bearing body 60 is in the storage position.

The Indian figure 4 Stop body 60' shown on the right assumes an active position. In the active position, the stop section 61 protrudes into the bearing cavity 2 in such a way that a stop surface 66 formed on a side wall of the stop section 61 lies in the movement path of the stop 32 of the driver 28 .

The two stop bodies 60, 60' are each acted upon by a compression spring 64 in the direction of the opening of the storage shaft 7. For this purpose, the compression spring 64 is supported on a wall of the storage compartment 7 opposite the opening of the storage compartment. The compression spring 64 acts on a pressure surface 63 of the stop body 60, 60', which can be formed by a depression.

The two stop bodies 60 , 60 ′, which are designed in the same way, have a waisted design between the pressure surface 63 and the stop section 61 . They form recesses 62. However, only one recess 62 is required for the functioning of the two stop bodies 60, 60'. The recess 62 has two inclined surfaces 62' pointing away from one another, which form ramps with which an end face of a locking pin 65 interacts.

The locking pin 65 is mounted in a bore 8 that extends between the two storage shafts 7 . The length of the bore 8 is less than the length of the locking pin 65 mounted therein. The two stop bodies 60, 60' arranged next to one another form mutually facing support shoulders and mutually facing recesses 62, which each interact with one of the two end faces of the locking bolt 65 pointing away from one another in such a way that the locking bolt 65 supported on the supporting shoulder 69 of a stop body 60' engages 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 storage position, whereas the one stop body 60' with its support shoulder 69 holds the locking pin 65 in this position.

The storage shafts 7 are covered by the cover plate 12. However, they are accessible from the rear of the base plate 1. For this purpose, operating openings 80 are located in the back, which open into the bottom of the storage shafts 7 . A tool, for example the blade of a screwing tool, can be engaged in the actuating openings 80 in order to displace the stop body 60, 60' which is in the operative position. At the in figure 4 illustrated operating position, this is the right stop body 60 '. If the stop body 60' counteracts the restoring force of the spring 64 shifted, the locking pin 65 can shift into its bearing bore 8 . This takes place 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 force-induced displacement of the other stop body 60 into the operative position.

Once again figure 9 can be seen, the stop body 60, 60' has laterally protruding limiting stops 70, with which it is prevented that the stop body 60, 60' leaves the bearing shaft 7 in the operative position. In the operative position, the limiting stops 70 bear against counter-stops, which are not shown.

To the in the figure 4 To bring the fitting shown in the right-hand actuation position into a left-hand actuation position, the energy accumulator, ie the spring strut 34, must be brought out of an operative position. This is done using a tool, for example the blade of a screwdriver, which is brought through the access opening 78 and with which the foot 38 is lifted from the support shoulder 6 so that the energy accumulator 34 can assume its position shown in FIG. In this position, the stop 32 lies in front of the stop surface 66 of the stop body 60' which is in the operative position. If the stop body 60' is now lifted from the operative position into the storage position using a tool through the actuating opening 80, the other stop body 60 is displaced into the position in FIG figure 6 shown active position. The locking pin 65 is shifted from left to right and engages in the recess 62 of the stop body 60' in order to hold it in the storage position. The locking pin 65 is then supported on the support shoulder 69 of the stop body 60 brought into the operative position.

With a tool, for example the blade of a screwing tool, the energy accumulator 34 can then be inserted into the in figure 6 be brought into the position shown, in which the foot 38 is supported on a supporting shoulder 6 . Here, too, the spring strut 34 crosses a center line of the fitting at an angle. In this left-hand actuation position, the handle can be rotated by 45 degrees, with a limit stop, with the stop 32 being acted upon by the energy accumulator 34 against the stop 9' of the base plate 1 and being able to be brought against the stop surface 66 of the stop body 60 by turning the handle 10.

It is considered advantageous that the left/right changeover is possible without the prior removal of covering means, for which purpose openings are provided in the rear of the fitting, through which a tool or the like can be reached in order to remove the stop bodies 60, 60 'Convert or to release the force accumulator 34 from a first functional position in order to then bring it into a second functional position.

3. Coupling between outside handle mandrel and inside handle mandrel

The fitting has a coupling formed by the drivers 28, 39 in order to bring the outside handle 10, which is placed on an outside handle mandrel 49, either with a mortise lock into a rotary connection position or into a release position. In the slewing ring position, the outer handle mandrel 49 is connected to the drive square 67 in a rotationally fixed manner. In the release position, this non-rotatable position is canceled. The outer jack mandrel 49 can be twisted without taking the drive square 67 with it. The driver 28, which forms a passive coupling element of the coupling, has a substantially rotationally symmetrical shape. The driver 28 is fixed, in the exemplary embodiment of the same material, to the presser mandrel 49 . The pusher mandrel 49 originates 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 arises from a broadside surface of a cylindrical portion formed from an outside of a cavity wall 30 . The stop 32 and the extension which is diametrically opposite the stop and which forms the fastening means 33 for the energy accumulator 34 originate from this outer wall. The cavity wall 30 surrounds a coupling cavity 29 with a substantially flat bottom and an inside of the cavity wall 30 that extends on an inner cylindrical lateral surface. The cavity wall 30 has at least one restraining recess 31 in the form of a radial opening through the cavity wall 30. In the exemplary embodiment, there are two such radial openings provided, each forming a bondage recess 31 and which are offset by 90 degrees to each other. In the center of the bottom of the coupling cavity 29 is the end of an axial bore 51, which extends through the entire handle mandrel 49 and in which a clamping screw 56 is inserted, which is supported with its head on the edge of the opening of the axial bore 51.

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 restraining element 41 is arranged. The restraining element 41 is in the figure 12 shown in a retracted position. This corresponds to the release position of the clutch. With a drive motor 45 rotating a drive shaft 46, the restraining member 41, which is a slider, can be brought from the release position to a rotationally entrained position. In the rotary driving position in the figure 13 is shown, an end portion of the restraining element 41 engages in the restraining recess 31 of the cavity wall 30 . For this purpose, the restraining element 41 is slidably mounted in a storage shaft 44 . The restraining element 41 has an essentially square cross-section. The Storage Shaft 44 also has a four-edged internal cross-section, so that the restraining element 41 is supported and guided in the bearing shaft 44 so that it cannot rotate.

The restraining element 41 has a cavity which is open to a polygonal side of the restraining element 41 . A U-shaped bearing body 43 is inserted into the opening of the cavity. A compression spring 42 extends between the two U-legs of the bearing body 43. The shaft 46, which can be driven in rotation by the drive motor 45, extends through the compression spring 42. A threaded element 47 is seated on the shaft 46 and engages in the intermediate spaces of the compression spring 42 in the form of a helical turn. If the drive motor 45 is rotated, the compression spring 42 is tensioned either against one of the two U-legs or against the other U-leg, depending on the direction of rotation of the drive motor 45, so that a force is exerted on the restraining element 41 either in the direction of the restraining recess 31 or from the restraining recess 31 away is exercised.

Is based on the in figure 12 shown release position, the shaft 46 is rotated in such a way that the compression spring 42 is displaced to the left, the restraining element 41 is applied in the direction of the restraining recess 31, so that it is in the figure 13 can assume the following position shown, in which the restraining element 41 engages in the restraining recess 31 and thus couples the two coupling members 28, 39 to one another in a torque-proof manner. This corresponds to the clutch position of the clutch.

Is based on the in the figure 13 rotary driving position shown, the shaft 46 is rotated in the opposite direction, so that the compression spring is shifted to the right, the restraining element 41 is shifted in the direction of the restraining recess 31, so that again in the figure 12 shown release position is reached. The drive motor 45 does not need to run against an end stop in either direction or in the other direction. If the spring 42 is displaced fully to the left or fully to the right, the threaded element 47, which may be a thread, emerges from the helix formed by the spring element and can rotate idly.

the figure 14 12 shows an operating position that essentially corresponds to FIG. 12, but with the coupling member 39 seated on the inside pusher mandrel formed by the square drive 67 being rotated relative to the coupling member 28 in such a way that the restraining element 41 is not aligned with the restraining recess 31. If the drive motor 45 is actuated in this rotary position, the spring element 42 tensions and displaces the restraining element 41 in the direction of the cavity wall 30 until it abuts against the inside of the cavity wall 30 . In this state, the coupling member 28 connected to the outer pusher mandrel 49 can be rotated until the restraining recess 31 occurs in an escape position relative to the restraining element 41, which is then pushed into the restraining recess 31 by the force of the relaxing spring 42.

the figure 15 1 shows that the axial length of the coupling member 28 extends substantially over the entire depth of the bearing cavity 2. FIG. The end face 40 ′ surrounding the bearing collar 40 rests against the broad side of the cover plate 12 pointing towards the base body 1 . The edge 30 ′ rests against the broad side of the cover plate 20 pointing towards the base body 1 . The two cover plates 12, 20 thus form with their broad sides bearing surfaces for the driver or the coupling member 28. The active coupling member 39, which carries the drive motor 45, which is rotated during the rotary movement of the coupling member 39, is completely accommodated in the coupling cavity 29. It non-illustrated cables are provided, with which the drive motor 45 is connected to the electronic control device, which is located in the housing 16. The coupling member 28 is thus in the bearing cavity stored that the radially - based on the axis of rotation A - outwardly facing peripheral surface of the cavity wall 30 has a free distance to a bearing cavity 2 delimiting wall 2 'has.

The coupling member 39 forms an end face 48 ′ adjoining the bearing collar 48 and resting against the broad side face of the cover plate 20 .

The cover plate 20 has an arcuate slot 59 extending around the bearing bore 21 and extending over an angle of 90°. A stop pin 58 of the driver 39 engages in this curved slot 59 . Provision is therefore made in particular for the active driver 39 to be able to rotate only through a limited angle of rotation and in particular through an angle of 90 degrees.

4. Fastening means for fastening the fitting to a door leaf

A further aspect of the invention relates to fastening slots 4, 5 and 86 which are arranged in the base plate 1 and which are intended for receiving fastening elements 25, 26. The fastening slots 4, 5, 86 extend parallel to the direction of extension of the elongated base plate 1. The fastening slots 4, 5, 86 have a first longer section in which the fastening element 25 in the plane of extension of the base plate 1 in a direction towards the handle mandrel 49 or 67 or can be moved from the handle mandrel 49 or 67. As a result, on the one hand, the distance between the fastening element 25 and the spindle 49, 67, and on the other hand, the distance between the two fastening elements 25 can be changed. As a result, the fitting can be adapted to regionally different distances between the axis of the handle and the axis of the locking cylinder.

The mounting slot 4, 5, 86 has an end portion 4 ', 5' or 86 ', which has a greater width than the longer portion of the mounting slot 4, 5, 86. Through this end portion 4', 5', 86 'can of a fastening element 25, 26 can be inserted into the fastening slot 4, 5, 86 from the back of the base plate 1. This is done by moving the fastening element 25, 26 in a direction perpendicular to the plane of extension of the base plate 1.

the Figures 17 to 20 show cross sections through the various attachment slots 4, 5, and through an end portion 5 '. The attachment slots 4, 5, 86 have a portion that has a small width. This section extends from the rear of the base plate 1 to a widened section 75, 76, which runs in the front side of the base plate 1 pointing away from the rear. The base plate 1 is covered by the cover plate 12 in this area. The fastening slot 5 thus forms an undercut, elongated opening with a T-shaped cross section, the bottom of which is formed by the cover plate 12 . In the end portions 4 ', 5' and 86 'of the mounting slot is not undercut. In these end portions 4 ', 5', 86 ', the mounting slot has a width which corresponds to the width of the widened portion 75, 76.

the figure 18 shows a first fastening element 25 which is inserted in a fastening slot 5. FIG. Since the mounting slots 4 and 5 are designed essentially the same, in the figure 19 Fastening element 25 shown in fastening slot 5 can also be arranged in fastening slot 4 . The fastening element 25 has a circular disk-shaped head 25', the width or diameter of which is slightly smaller than the width of the widened section 75. The head 25' is followed by a shaft which has at least two axial sections. A first axial portion of the shank 25' forms a neck 25'' having a diameter which is less than the diameter of the head 25 'and is less than the width of the mounting slot 5. This neck 25' extends within the base plate 1.

A second section of the shaft 25‴ connects to the neck 25″, which protrudes backwards from the base plate 1 and which can protrude through the door leaf to which the fitting can be attached. A head 25 'opposite end of the shaft 25' has an opening of a threaded bore into which a fastening screw can be screwed.

To mount the fastening element 25, the head is inserted through the end section 4' or 5' or 86' from the rear of the base plate 1. This continues until the end face of the head 25' strikes the cover plate 12. If the fastening element 25 is inserted into the fastening slot 4 , this is done until the head abuts against the housing 16 which covers the fastening slot 4 or the widened section 75 . From this position, the fastening element 25 can be brought within the fastening slot 4, 5 to the position suitable for fastening. The reference number 85 designates a ring which is located in the transition area between the neck 25" and the section of the shaft 25‴ protruding from the base plate 1.

The fastening slot 5 opens into a lock cylinder passage opening 3. In this fastening slot 5, the end section 5' is formed by a narrowed section of the lock cylinder passage opening 3, in which a flange section of a lock cylinder can be accommodated. If this end section 5' is used to receive a flange section of a lock cylinder, then the cover plate 12 has a lock cylinder passage opening 14 which is a correspondingly large amount away from the handle mandrel 49 is removed. With this type of use of the fitting on a lock with a large distance, no fastening element can be arranged there.

In one type of use of the fitting on a lock with a smaller distance, in which the distance between the handle mandrel 49 and the axis of the lock cylinder is smaller, a fastening element 26 can be used in the end section 5', as is the case figure 20 indicates. The cover plate 12 used here has a lock cylinder passage opening 14 which is at a smaller distance from the handle mandrel 49, so that the end section 5' is covered by the cover plate 12. The end section 5' has an enlarged section 76 which extends immediately below the cover plate 12 and the width of which is greater than the width of the end section 5'. The fastening element 26 has a head 26', the diameter of which 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 lock cylinder passage opening 3. A head 26' adjoining the neck 26' is inserted with a precise fit into the end section 5'. The neck 26 'has a diameter which is greater than the width of the mounting slot 5 and approximately the diameter of the head 25' corresponds. A shank section of the shank 26″ connects to the neck 26‴, which can protrude through the door leaf and which can have a threaded bore 74 .

That in the Figures 23 to 25 The second exemplary embodiment shown shows a wide shield in which a fastening slot 86 is arranged next to the opening 3 in the lock cylinder. The two fastening slots 86 running parallel to one another and parallel to the lock cylinder passage opening 3 each have an end section 86' and otherwise have a shape like the fastening slots 4, 5, so that reference is made to the relevant statements. The distance between the two mounting slots 86 corresponds to the standardized distance between the fastening screws of a lock cylinder rosette.

At the in the figure 26 In the illustrated embodiment, the attachment slots 86 run parallel to an elongated opening 93 for the passage of a lock cylinder. The fastening slots 86 are assigned to the cover plate 20 here, which can be connected to the rear of the base plate 1 . Another fastening slot 4 runs centrally between the two longitudinal edges of the cover plate 20. The bearing bore 21 is located between the fastening slot 4 and the two fastening slots 86.

5. Fasten the cover plate 12 to the base plate with threaded shanks

the Figures 17 and 18 Figure 12 shows the threaded shanks 15 attached to the cover plate 12 on the side opposite the visible side, each of which originates from a head 15' which is connected to the back of the cover plate 12. The heads 15' may be welded or brazed to the back of the metal cover plate 12. However, they can also be glued to the cover plate 12 . This can be particularly advantageous when the cover plate 12 is made of plastic. However, it can also be provided that the threaded shafts 15 are made of the same material as the cover plate 12 . The threaded shafts 15 are preferably made of metal and are materially connected to the cover plate 12 in such a way that the front side of the cover plate 12, which forms a decorative surface, is not optically impaired by the attachment.

The length of the threaded shanks 15 is slightly less than the thickness of the base plate 1. The base plate 1 has a fastening opening 27 for each threaded shank 15, which extends through the entire base plate 1. On your the side facing the cover plate 12 has the fastening opening 27 a widening 27 'for receiving the head 15'. On its side facing the rear of the base plate 1, the fastening opening 27 also has a widening 27", which serves to accommodate a nut 84, which can be screwed onto the thread of the threaded shaft 5. The front side of the nut 84 is in the fastened state in the widening 27". The face of the nut 84 has indentations or a profile on which a screwing tool can act.

The fastening openings 22, 27 can in particular have sections which are arranged one behind the other in the axial direction and which have a different diameter.

Of the figure 18 It can be seen that the threaded shank 15 not only extends through the fastening opening 27 of the base plate 1, but also through a fastening opening 22 in the cover plate 20, which is embedded in a depression in the back of the base plate 1. The fastening opening 22 can have a countersink on which the countersunk head of the nut 84 can be supported.

In particular, an even number of threaded shafts 15 is provided. The number of threaded shanks 15 with which the cover plate 20 is attached to the cover plate 12 can also be an even number and preferably be four, six or eight.

6. Attachment of the handle to the handle mandrel

the figures 8 , 11 , 15 and 21 show a driver 28 which has a bell-shaped shape. The driver 28 has a circular end face with a bearing collar 40 in a bearing bore 13 of the cover plate 12 is stored. The driver 28 or its end face or the end face 40 'of the bearing collar 40 arises from the same material as the square mandrel 49. The mandrel 49 has a bore 51 which extends in the axial direction of the mandrel 49. The bore 51 has a countersink, which is located in the center of the bottom of the clutch cavity 29 and continues to the free end of the handle mandrel 49. The bore 51 runs offset to the central axis of the handle mandrel 49, so that it has an inclined surface 50 at the free end of the pusher mandrel 49 penetrates.

The inclined surface 50 begins at a step which is distant from the free end of the mandrel 49 and continues with a reduction in the cross-sectional area of the mandrel 49 to the free end of the mandrel 49 . There it ends at an end face of the handle mandrel 49 with a reduced cross-section.

A clamping element 52 in the form of a wedge is provided, which has a wedge surface 54 which 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 which extends in the bore 51 is screwed. The countersunk head of the clamping screw 56 lies in the lowering of the bottom of the coupling cavity 29.

The angle of inclination of the wedge surface 54 corresponds to the angle of inclination of the inclined surface 50, so that a pressure surface 53, which faces the wedge surface 54, runs parallel to a polygonal surface of the handle mandrel 49, which faces the inclined surface 50. By turning the clamping screw 56, the clamping element 52, which has the shape of a wedge, can slide along with its wedge surface 54 on the inclined surface 50, the distance between the pressure surface 53 and the polygonal surface of the presser mandrel 49 lying opposite it changing.

The handle 10 can be connected to the handle mandrel 49 as follows. The cover plate 12 is not attached to the base plate 1. The handle mandrel 49 is inserted through the bearing bore 13 of the cover plate 12 until the annular collar 40 is in the bearing bore 13. Then the handle mandrel 49 is pushed into the polygonal opening 11, which is preferably a square opening, until the face of the handle 10, in which the square opening 11 opens, rests against the face 40' of the bearing collar. A radially outer area of the end face of the pusher 10 projects beyond the bearing collar 40 in the radial direction. The clamping screw 56 is then turned until the clamping element 52 assumes a clamping position in which the pressure surface 53 applies force to the inner wall of the square opening 11.

The cover plate 12 can then be fastened to the base plate 1 by means of the threaded shanks 15 and the nuts 84 screwed onto it.

At the in the Figures 26 to 20 In the exemplary embodiments illustrated, the pusher 10 is connected directly to the coupling member 28 . The coupling member 28 carries a square extension 87 which is formed from the same material as the coupling member 28 . The square extension 87 can be inserted into the square cavity of the pusher 10 . A fastening screw holds the handle 10 on the square extension 87.
