Description

The invention relates to a door handle mounting device for the attachment of a door handle on a door leaf. Furthermore, the invention relates to a door lock with such a door handle mounting device.

Doors are usually equipped with a door handle, which may be formed, for example, as a door handle, equipped to open the door. For example, to open the door, the door handle is turned down about an axis of rotation, thus releasing a latch of a corresponding door lock. The door handle must be stored on the door leaf, so that the operation is possible. In modern locking systems, especially locking systems for commercial properties, while an electrically controllable coupling between the door handle and a corresponding case of the door lock can be provided. The coupling can be activated for example by means of a transponder, so as to allow only authorized persons opening the door and a corresponding access. Accordingly, the door handle is connected only to the case of the door lock when the electric clutch is closed. Therefore, a spring of the case can not always provide a restoring force for the door handle after its operation. Therefore, a corresponding return mechanism for adjusting the door handle is usually also provided in a neutral position, which holds the door handle in the decoupled state in the neutral position. Such a return mechanism may for example comprise a spring element.

From the DE 20 2005 015 858 U1 a door fitting for mounting on a door leaf is known, which has a Unterrosette for supporting a door handle. Furthermore, the door fitting on a return mechanism for pushing up the door handle. The return mechanism in this case has a spring element, which is connected to a limiter element with a square pin on which the door handle is mounted. Furthermore, the door fitting comprises a detent spring for latching fixation of Door handle, which serves as an axial securing. Overall, the door fitting described here requires a large number of different parts.

From the DE 37 10 883 A1 a door fitting with door actuator and door plate is known in which a curved coil spring provides a corresponding restoring force in a neutral position. A movement of a door actuating element described here is suitably limited by stops in the range of movement of a case, so that the door fitting is unsuitable when a coupling is provided between the case and the door operating element.

In the DE 20 2005 004 381 U1 a return spring unit for a door fitting is described. A corresponding restoring force is provided by a coil spring available. For a sufficiently high restoring force while a large space is required and, incidentally, such a return spring unit can have a big game in a neutral position of a door handle.

Object of the present invention is to provide a structurally simple and secure door handle mounting device for the attachment of a door handle on a door leaf, which is adapted to be used together with an electrically controllable coupling. Furthermore, it is an object of the present invention to provide a structurally simple and secure door lock, which is suitable to be used together with an electrically controllable coupling.

The objects of the present invention are solved by the independent claims and the aspects discussed below. The dependent claims describe further preferred embodiments and modifications of the invention. Advantageous embodiments of the door handle mounting device are to be regarded as advantageous embodiments of the door lock and vice versa.

A first aspect of the invention relates to a door handle mounting device for mounting a door handle on a door leaf with at least one door plate and with a bearing assembly. The bearing assembly in this case has a bearing element for rotatably supporting the door handle about an axis of rotation, wherein the axis of rotation is predetermined by a guide element of the bearing assembly and wherein the bearing element with respect of the door plate has on one side a fastening element for fastening the door handle and on a side lying opposite the axis of rotation a connecting element. The fastening element can be designed, for example, as a pin element, in particular as a square pin. The connecting element is preferably designed to be connected to an electrically activatable coupling which, in the coupled state, allows power transmission from the door handle to a latch of a door lock. Conversely, the power transmission can be open in the uncoupled state, so that by means of the door handle a case of a door lock can not be opened.

Furthermore, the bearing arrangement preferably has an axial securing for fixing an axial position of the bearing element relative to the guide element. In addition, the bearing arrangement preferably has at least one spring element, by means of which the bearing element is rotatable relative to the guide element automatically about the axis of rotation in a neutral position. Thus, a correspondingly mounted door handle is automatically held in the decoupled state of the electrically controllable clutch in the neutral position or zurückverstellt in this after rotation of the door handle or the bearing element. At the same time, a certain actuating force is required in the decoupled state. A corresponding handle set acts as well in the decoupled state of high quality, as this then does not feel loose or has excessive play. In addition, the bearing assembly preferably comprises a driver, by means of which a restoring force of the spring element for rotating the bearing element in the neutral position of the spring element to the bearing element is transferable. In this case, the driver and the axial securing are preferably integrally formed as Sicherungsmitnehmerelement, which is preferably arranged with respect to the door plate on the same side as the connecting element.

In the case of the door lever fastening device, it is therefore preferable for both the axial securing function and the driver or force transmission function to be provided by a single component, the securing driver element. As a result, the door handle mounting device preferably requires a particularly small number of parts, which makes it structurally simple. Overall, as manufacturing and assembly costs can be reduced. By the preferred arrangement of Sicherungsmitnehmerelements on the same side with respect to the door plate as the connecting element for connection to the electrically controllable coupling can also be increased the robustness of the door handle mounting device against unwanted manipulation. Accordingly, the door handle fixing device can be particularly safe.

By such an arrangement, namely the Sicherungsmitnehmerelement in the installed state of the door handle mounting device is preferably located on a door leaf side facing the door plate. Thereby, the Sicherungsmitnehmerelement be covered by the door plate at least with respect to an access side of the door. The access side can also be described as the side on which the door handle mounting device is arranged on the door plate. In general, this page can also be accessible to unauthorized persons. Unauthorized persons may be, for example, persons without a transponder for opening the door. The described arrangement of Sicherungsmitnehmerelement this can be removed, for example, only at a disassembly of the door plate of the bearing element. Only then is a further non-destructive disassembly of the door handle mounting device possible, in particular the removal of the bearing element from the guide element. The door handle mounting device can be designed so that from the access side, the coupling is accessible only after removal of the bearing element. In particular, the door plate can be mounted in such a way that it can only be released if it has already been possible to gain access to a space closed by the corresponding door. The door plate can thus for example be mounted so that disassembly is only possible from one side of the door facing away from the access side. This means that only the electrically controllable coupling must be closed, then the door must be opened and only then a possibility for disassembly of Sicherungsmitnehmerelements without destroying the door handle mounting device is possible. Accordingly, it can be seen how the arrangement of the Sicherungsmitnehmerelements can increase security.

The spring element can be mounted on the door handle mounting device, in particular on the door plate and / or the guide element. The door plate can also be designed as a guide element to further reduce the number of parts required. The Sicherungsmitnehmerelement may be formed as a substantially flat and / or disk-shaped element, in particular as a retaining ring with one or two support areas for one or both ends of the spring element. In particular, that can Sicherungsmitnehmerelement thus have two spaced bearing areas. The Sicherungsmitnehmerelement can be made particularly cost-effective especially in a stamping and / or deep drawing process. The basic shape can be punched from a sheet and respective particular projecting bearing areas are introduced during deep drawing.

The axial securing of the Sicherungsmitnehmerelements determines the position of the bearing element relative to the guide element along the axis of rotation, in particular, thus, an axial displacement of the bearing element can be prevented. This axial securing can act on one side in an axial direction. Accordingly, the bearing element on the other side of the door plate having a stop, by means of which the axial movement of the bearing element is limited relative to the guide element in the other direction along the axis of rotation. This axial securing in the form of the stop may for example be formed integrally with the bearing element. Alternatively, the axial stop can also be permanently connected to the bearing element, for example by soldering, gluing and / or welding. By a permanent and permanent connection of the stop with the bearing element can thereby increase security, as a removal of the bearing element only by a destructive disassembly or disassembly of Sicherungsmitnehmerelements is possible. The Sicherungsmitnehmerelement can be plugged, for example, for mounting on the bearing element after it has been inserted into the guide element to the stop. The bearing element may for example have a corresponding groove into which the Sicherungsmitnehmerelement engages.

Advantageously, the Sicherungsmitnehmerelement can also form part of the bearing of the bearing element, in particular together with the guide element. For example, the Sicherungsmitnehmerelement record together with the guide element bending forces, which can be initiated, for example by a support on the door handle in the bearing element. For example, the Sicherungsmitnehmerelement rest with a surface transversely, in particular perpendicular to the axis of rotation of the guide element.

The guide element may be part of the door plate or be formed by the door plate itself. As a result, very few parts are needed. For example, that can Doors also be a rosette of a handle set. The door handle mounting device can be attached directly to the door leaf, but also indirectly by means of other parts, such as a door lock and / or a case of the door.

The fastening element may be formed, for example, as a square pin. In the installed position of the door handle mounting device on a door leaf, the fastening element is preferably arranged on a side facing away from the door leaf relative to the door leaf and the side of the bearing element with the connecting element then faces corresponding to the door leaf. Usually, many door handles have a standardized connection opening, which are designed for connection to a corresponding square pin element. Accordingly, the door handle mounting device or the fastening element can be designed to be connected to a plurality of different door handles, in particular door blades and / or door knobs.

The connecting element can be permanently connected to a part of the coupling. Then the clutch internally releases the power flow or closes a corresponding power flow to actuate the latch. Alternatively, the connecting element can only come into engagement with the coupling, for example, form-fitting when the clutch is closed. Such a door lock can be particularly robust against manipulation of the coupling and thus unauthorized opening of the lock.

Preferably, the Sicherungsmitnehmerelement is secured against rotation about the bearing element along the axis of rotation in order to transmit forces accordingly. Such a fuse can be designed, for example, as a cost-effective positive connection.

The axis of rotation can be predetermined for example by a passage opening in the guide element. The guide element may be formed, for example, as a bearing plate. Alternatively or additionally, the guide element may also comprise a bearing housing and / or a ball bearing. In the simplest case, the guide element is merely a sleeve, in particular a plate-shaped sleeve, for supporting the bearing element. The guide element, in particular parts thereof, may be fastened to the door plate. In particular, the door plate may comprise a two-part inner door panel, whereby the Door handle mounting device can be easily mounted. The guide member may be clamped between these two door inner shield elements, for example in a groove, so that it is possible to dispense with additional fixing elements. Alternatively, the door plate itself also form the guide element.

In a further advantageous embodiment of the door handle mounting device, it is provided that the spring element is held on the door plate spaced from the axis of rotation in an arcuate path and is connected to the bearing element by means of the Sicherungsmitnehmerelements at its two ends for transmitting power, wherein preferably the spring element on the bearing element at least in the neutral position exerts an additional biasing force, which acts substantially transversely to the axis of rotation. The spring element can be a low-cost standard component and allows space-saving high restoring forces to keep the door handle safely in the neutral position. This can result in the door handle mounting device a particularly high quality feel.

The spring element may abut, for example, on a surface transverse to the axis of rotation, in particular at right angles to the axis of rotation of the Sicherungsmitnehmerelements, the guide element and / or the door plate. By means of the Sicherungsmitnehmerelements a rotationally about the axis of rotation acting force of the spring element can be transmitted to the bearing element. By rotating the bearing element from the neutral position, the spring element is stretched or compressed, for example, so that the restoring force is generated.

Preferably, the biasing force acts in the installed position substantially vertically downwards on the bearing element. Upon cancellation of the biasing force or a change in the biasing force, a typical door handle operation pushes the bearing element further in the same direction. As a result, the door handle fastening device has a particularly low clearance. For example, if a person presses the door handle to open a door down, the bearing element is already biased in this direction and is there on the corresponding storage. As a result, the operator can no longer feel any play in a vertical direction when turning the door handle. Accordingly, parts of the door handle mounting device, in particular the bearing element and / or the guide element can be manufactured with less stringent manufacturing tolerances.

Preferably, the spring element is designed as a helical spring, which can provide a particularly space-saving high return forces. In particular, the use of a compression spring is useful because the spring element can be so particularly resistant to permanent deformation. Corresponding restoring forces are created by compression and / or expansion of the spring element when the bearing element is rotated, which at the same time also causes the securing cam element to rotate and thus deforms the spring element.

The longitudinal extent of the spring element preferably follows the arcuate path. The door plate may accordingly have an arcuate Aufhahmebereich for the spring element. Arcuate may preferably correspond to at least a portion of a circle. In particular, the receiving area and thus also the spring element can have a regular curvature.

The spring element is preferably designed to be able to rotate the door handle element together with the bearing assembly or the bearing element in the neutral position when no external forces act. With a corresponding design of the spring element, therefore, a respective weight of a door lever element can also be taken into account. In particular, a square pin element of the bearing assembly can be automatically rotated by means of the spring element in the neutral position.

Over the entire length of the spring, the spring element can be spaced transversely, in particular at right angles to the axis of rotation constant from this. The bearing assembly may be formed, for example, as a radial bearing, which allows only a rotation of the bearing element relative to the guide element along the axis of rotation and blocks an axial movement.

An actuation of the door handle can in particular mean a rotation of the bearing element about the axis of rotation. After completing an operation, the bearing element and thus attached door handle can turn automatically back to the neutral position. By means of the bearing arrangement, therefore, a door handle can be rotatably mounted on the door plate on a door leaf, wherein the door handle can be connected by means of the coupling with the case of the door lock. The door plate can also be designed as a fitting. The door fitting can be defined as a door plate plus door handle. The bearing assembly may be formed, for example, as a ball bearing or sliding bearing, in which also a part of the door handle can be rotatably mounted. The door handle can be performed in addition to the bearing element with on the guide element. Optionally, the door handle can be connected by the coupling with a bolt, which can then also be operated with the door handle. In particular, in a bidirectionally rotatable door lever mounting device, this may be useful.

The trap can automatically snap when closing the door because of a beveled side in a corresponding recess of a door frame. This keeps the door in the closed position. By pressing the door handle with the clutch closed, the case pulls out of the corresponding holding element or the corresponding recess of the door frame, so that the door can be opened. The door handle fastening device can also be designed as a latch lock set or mortise lock set, in particular together with a door lock.

In a further advantageous embodiment of the door lever fixing device, it is provided that the bearing arrangement is designed to allow a bidirectional rotation of the bearing element relative to the guide element from the neutral position. This allows, for example, to secure the door handle in different positions. As a result, the door handle fixing device can be used for both sides of a door, without having to be changed constructively. Accordingly, a high degree of standardization and common parts can be achieved. The door handle mounting device may thus be adapted so that door handles can be attached thereto in at least two different positions. Thus, the door handle mounting device is suitable for both left and right mounting.

Alternatively or additionally, there may be two different actuation possibilities with corresponding actuation functions. For example, by depressing the door handle, a trap can be opened. When turning in the other direction, so for example, a pulling up of the door handle instead of depressing, an additional function of the door lock can be actuated. For example, by pulling up the door handle, the door lock can be locked.

In a further advantageous embodiment of the door lever fixing device, it is provided that at least one stopper element is arranged on the guide element, by means of which a maximum angle of rotation of the bearing element is limited with respect to the neutral position, wherein the at least one stopper element is preferably adapted to engage at maximum rotational angle with the Sicherungsmitnehmerelement. Preferably, in a bearing arrangement designed for bidirectional rotation, the door handle mounting device comprises two stopper elements in order to limit the maximum angle of rotation in both directions of rotation. Overall, as defined a final position when pressing the door handle can be specified, creating a particularly high-quality operation impression arises. In addition, so particularly good abusive high actuating forces can be absorbed by the door handle mounting device. This includes, for example, a support or climbing on the door handle. The stopper elements can for example be designed as stop elements and / or initiate forces when reaching the maximum angle of rotation directly into the door plate and / or the guide element.

In a further advantageous embodiment of the door handle mounting device, it is provided that two stop elements are provided on the door plate, which mutually support one end of the spring element when the bearing element is rotated about the axis of rotation relative to the guide element. In particular, this support can take place in the direction of rotation. These stop elements thus allow a power transmission from the spring element to the door plate and to build up a reverse torque correspondingly, which acts on the bearing element via the Sicherungsmitnehmerelement. By rotation of the door handle or the bearing element, for example, the driver element at one end of the spring element (it takes off) dissolves, while the other end of the spring element is pressed by means of the Sicherungsmitnehmerelements against the corresponding, located in the longitudinal direction of the spring element end stop element. This causes, for example, a compression of a helical spring and thus the generation of a restoring force.

In a further advantageous embodiment of the door handle mounting device, it is provided that at least one of the stop elements on a spring-side surface a compensation element is arranged. By means of this compensating element, in particular after an assembly of the remaining door lever fastening device, a rotational play can be compensated. For example, the compensation element may be formed as a plate, balance plate, leveling plate or washer. As a result, manufacturing tolerances can be compensated so far, even at the slightest rotation of the Bearing element, the spring element comes directly at one end in contact with the stop element or the compensation element arranged thereon and lifts from the Sicherungsmitnehmerelement. The spring element thus comes directly at the smallest turns at one end exclusively in contact with a support region of the Sicherungsmitnehmerelements. As a result, the feel of the door handle mounting device is particularly valuable, since so no or only a particularly small loose rotating area exists around the neutral position. Loose rotation means that no restoring force is built up yet. For the assembly or in the manufacturing process, a number of different thickness compensation elements can be provided in order to allow compensation, depending on the existing tolerance.

The compensating element can advantageously also have at least one projection for fixing the guide element on the door plate. Thus, the compensating element can also serve for attachment of a door plate on the guide element, in particular a multi-part door plate.

The door plate may have at least one access opening, through which a respective one of the compensating elements can be introduced into a position between the stop element and the spring element in the already partially assembled state. This makes installation particularly easy and fast. In particular, so the compensation element can be easily replaced by the trial-and-error principle until its necessary thickness was determined. As a result, expensive measuring methods for selecting a suitable compensation element can be avoided.

In a further advantageous embodiment of the door lever mounting device, it is provided that at least one of the stop elements or one of the compensating elements has a through opening through which at least one support portion of the Sicherungsmitnehmerelements is guided during rotation about the axis of rotation to with the support area upon rotation of the bearing element in Contact with the respective end of the spring element to contact or with this to solve the contact with the respective end of the spring element. Contacting and releasing the contact is determined depending on the direction of rotation and previous state. Through such a passage opening, the door handle mounting device can be particularly compact. In particular, so respective stop element, balancing elements and the Sicherungsmitnehmerelement in Substantially in the same axial region along the axis of rotation to be arranged in the door handle mounting device, without this interfering with each other and / or can collide with each other at corresponding rotations about the axis of rotation.

In a further advantageous embodiment of the door handle mounting device, it is provided that the spring element is designed as a compression spring; and wherein in particular the compression spring has at its ends in each case an end plate element. In particular, the compression spring may be formed as a helical spring. With a compression spring, a high restoring force can be generated particularly space-saving. The Endplattenelemente are preferably held in the respective last spring winding of the coil spring. The end plate elements may serve as an additional guide and / or abutment for a support area of the Sicherungsmitnehmerelements. This ensures a particularly safe power transmission. The end plate elements may for example consist of a plastic. The Endplattenelemente can positively stuck with paragraph in one end of the coil spring and / or rest.

In a further advantageous embodiment of the door handle mounting device, it is provided that the Sicherungsmitnehmerelement is positively secured against rotation on the bearing element; wherein the Sicherungsmitnehmerelement is in particular designed as a clip element, which comprises the bearing element at least partially. The positive rotation lock is particularly compact and inexpensive. In particular, can be dispensed with additional fasteners. An education as a clip element allows a particularly simple and quick installation and / or disassembly of Sicherungsmitnehmerelements. For example, the Sicherungsmitnehmerelement may be formed as a substantially horseshoe-shaped plate which is snapped onto the bearing element, in particular in a groove of the bearing element.

In a further advantageous embodiment of the door handle mounting device is provided that the Sicherungsmitnehmerelement adjacent to the axis of rotation, preferably adjacent, is arranged to the guide element. As a result, the door handle mounting device has particularly low rocker arms. Thus, the door handle mounting device can still be very robust with low material thicknesses.

In particular, the guide element and / or the door plate can be designed to be particularly thin-walled. In this case, the Sicherungsmitnehmerelement these parts by an immediate abutment or rest also supported and / or serve as part of the storage of the bearing element.

In a further advantageous embodiment of the door handle mounting device, it is provided that the door plate comprises an outer door plate part and an inner door plate part, wherein the inner door plate part has two inner door plate elements and preferably wherein the two inner door plate elements together have a receiving area for receiving the guide element and the spring element, and the outer door shield part fixes the two inner door shield elements relative to one another on the guide element. For a particularly space-saving design, the receiving area for receiving the guide element can also simultaneously form the receiving area of the spring element. Alternatively, these two receiving areas may be formed separately, so that they can be adapted particularly well to respective requirements. The two inner door shield elements together may comprise at least partially the guide element and / or the spring element in order to keep it structurally simple. Thus, overall, the assembly and construction of the door handle mounting device can be particularly simple. In particular, can be dispensed with additional fixing elements, such as screws, or their number can be at least particularly low.

A two-part inner door plate allows a particularly secure receiving the guide element by inserting into a receiving area and a positive holding therein. The outer door plate may be at least partially slipped over the two inner door plate elements, for example, to hold them so. At the same time, a protected from external access interior can be formed in the manner of a housing. The outer door plate can be screwed, for example, for securing to the two inner door plate elements. The outer door plate can have a positive receiving area for the two inner door shield elements. In addition, the spring element can also clamp the two inner door shield elements against the outer door plate. As a result, an additional tolerance compensation is possible. Tolerance compensation enables parts with lower requirements to be made of them Manufacturing tolerances are used, whereby the manufacturing costs can be particularly low.

In a further advantageous embodiment of the door handle mounting device, it is provided that the door handle mounting device is adapted to be attached to a door mounted in the lock case; in particular by means of a fastening device of the door lever fastening device which comprises at least one fixing element movable along at least one axis and at least one immovable fixing element. Due to this mobility of at least one of the two fixing elements, a respective tolerance compensation between at least two attachment points on the door lock box can be made available. Preferably, the fastening device is arranged on the door plate and / or a part thereof. The respective fixing elements may be formed, for example, pin-shaped. The tolerance compensation of the distance between two corresponding mounting holes in the lock case can preferably be done in the vertical direction in the installed position. For example, the fastening device preferably comprises two immovable pin elements and two movable pin elements, which are jointly held on a sliding body, which is guided in two grooves and / or recesses of the door plate. The slider can be designed so that it is also slightly tilted in the respective grooves and thus a further tolerance compensation is provided. For this purpose, the slider can be held with play in the grooves, for example.

The door plate may be at least partially formed of a metal material, in particular brushed on the outside aluminum or stainless steel. An outside brushed surface is preferably provided only on the outer door shield part.

In a further advantageous embodiment of the door handle mounting device, it is provided that the door lever mounting device comprises the electrically controllable coupling, by means of which in the coupled state, a torque at an actuation of the door handle to a latch of a door lock to the opening is transferable and by means of which in the coupled state no torque at the operation of the door handle on the case to the opening is transferable. In an installed position of the door handle mounting device to a door so in the coupled (closed) state, the bearing element is mechanically connected to the trap and decoupled (Open) state unconnected, so that each forces can be transmitted from the door handle or not transmitted.

The clutch is electronically actuated, in particular by means of an electric motor. The electrical coupling can also contain a respective power supply, for example in the form of batteries and / or rechargeable batteries. This provides easy retrofitting for doors. Alternatively, the coupling can also be connected to a mains supply of the house. Likewise, the door handle mounting device and / or the electrically controllable coupling may include respective electronics and / or motors. It can be provided a radio receiver to control the clutch wirelessly. A corresponding radio actuation of the clutch can be done for example by active and / or passive transponder. The electronically controllable coupling or door lever fastening device may also include an RFID reader and / or an input device for inputting a pin code for driving them. In general, a variety of access control mechanisms may be used in conjunction with the electronically controllable clutch and door handle mounting device.

Preferably, all components which enable a power transmission from the door handle of the case, at least behind the door plate, in particular the outer door plate, arranged concealed. As a result, the door handle mounting device from manipulation for unauthorized opening of the appropriately equipped door is particularly protected. However, it may also be partially arranged components, such as batteries, outside the door panel, preferably behind a separate panel. As a result, for example, respective batteries can be replaced quickly and easily, without the door handle mounting device itself must be dismantled and / or without this the risk of unauthorized access is increased.

In a further advantageous embodiment of the door handle mounting device, it is provided that the fastening element of the bearing element has on the outside at least one fixing element by means of which the door handle is fixable to the fastening element, wherein the fixing element is held by a spring in a locking position, in which arranged on the fastening element Door handle is fixed to it. For example, an additional, movable cylinder can be provided on the fastening element, which in a corresponding recess in a mounting opening the door handle can latch. This results in an axial fixation of the door handle along the axis of rotation of the fastener.

In a further advantageous embodiment of the door handle mounting device, it is provided that the bearing element has an inner channel with an access opening on the side of the connecting element, in which the spring for holding the fixing element is arranged in the locking position, wherein by a force on the spring in the channel, in particular a pressing, an adjustment of the fixing element from the locking position can be released in a release position. In particular, in a coupling of the fixing element with the spring element by applying force to the spring this can be adjusted directly in the release position. Alternatively or additionally, gravity can be used instead of a connection between the spring and the fixing element for adjusting into the release position when the spring is pressed down. Thus, it is possible to dispense with a connection between the spring and the fixing element, for example gluing or soldering. In the release position, the door handle disposed on the fastener is no longer axially fixed thereto and can be removed. For example, the door handle can then be removed by axial displacement along the axis of rotation or removal from the fastener. The described axial fixation is particularly space-saving. By arranging the access opening on the side of the connecting member, the door handle can be disassembled only from the door press fixture when the door press fixture is disassembled from the door panel. As a result, the door handle mounting device is particularly secured against unwanted manipulation. In particular, the door handle can thus block in the fixed state, a removal of the outer door shield part of other parts of the door handle mounting device.

A further aspect of the invention relates to a door lever fixing device having at least one door plate for fastening a door handle to a door leaf and having a bearing arrangement, wherein the bearing arrangement comprises a bearing element for rotatably supporting the door handle about an axis of rotation which is predetermined by a guide element of the bearing arrangement, wherein the bearing element with respect to the door plate on one side has a fastening element for fastening the door handle and on a side opposite the rotation axis side a connecting element, which is adapted to be connected to an electrically controllable coupling, which in the closed State allows power transmission from the door handle to a latch of a door lock; wherein the fastening element of the bearing element has on the outside at least one fixing element, by means of which the door handle can be fixed to the fastening element, wherein the fixing element is held by a spring in a locking position, in which the arranged on the fastening element door handle is fixed thereto. This fixation offers the advantages already described above and can protect the enstprechende door handle mounting device from unwanted manipulation. The door handle mounting device may also include a door handle and be referred to as a lever handle accordingly.

Another aspect of the invention relates to a handle set with door handle mounting device according to the first aspect and an attached door handle.

FIG. 1 shows in a schematic perspective view of a door handle mounting device 10 for the attachment of a door handle 12 on a door leaf 58. The assembled state is in the schematic perspective view of FIG. 5 shown. The door handle 12 is formed here as a doorknob. The door handle mounting device 10 includes a door shield 14 and a bearing assembly 16. In FIG. 1 only parts of the door plate 14 are shown - a fully assembled representation is in FIG. 5 shown. The bearing assembly 16 in this case has a bearing element 18, on which the door handle 12 is rotatably mounted about an axis of rotation and which partially obscured by the clutch 28 attached thereto. The axis of rotation is predetermined by a guide element 20, which is designed here as a metallic plate. In a through hole of the guide member 20 while the bearing member 18 is rotatably mounted. In this case, the bearing element 18 has, on a side facing away from the door handle 12, a connecting element 66 which is designed to be connected to the electrically controllable coupling 28 mounted thereon and covering it. The connecting element 66 is in Fig. 6 to recognize, since the attached coupling 28 is not shown here. The connecting element 66 in this case represents a receptacle for the coupling 28 and can form one of the coupling 28 corresponding receiving space. The connector 66 may also be referred to as part of a pusher flange. As in the FIGS. 1 to 4 can be seen, the clutch 28 in this case has a receiving opening 50, which is designed here for receiving a regular pusher pin of a case 60 and a door lock. This region of the coupling 28 can also be referred to as a dome adapter for the square or coupling ring. On the door handle 12 side facing the bearing member 18, however, a fastener on which the door handle 12 is attached. In the figures, the fastener is substantially covered by the plugged door handle 12. The sides of the bearing element 18 may in this case be defined with respect to the guide element 20 and / or the door plate 14. The fastening element may in particular be a square pin, which allows a standardized attachment of a corresponding door handle.

The electrically controllable coupling 28 allows an electronic access control with the door handle mounting device 10. The clutch 28 in this case comprises the coupling pin 64, which is radially displaceable by means of an electric actuator. In the radially extended state while a positive connection for power transmission to the bearing element 18 is made, as shown in the FIGS. 1 to 4 is shown. The coupling pin 64 is thereby inserted into a recess of the bearing element 18 and the connecting element 66. The coupling is then in the coupled state. For coupling, the coupling pin 64 can be moved radially inward and for decoupling radially outward. A construction with reverse coupling direction is also possible. In the coupled state, a power transmission from the door handle 12 via the bearing element 18 and the connecting element 66 to a latch 60 of a door lock is possible. The trap 60 is in FIG. 5 shown. By turning the door handle 12 to the by the Guide element 20 predetermined rotation axis can then be pulled out of a door frame according to the case 60 and the door can be opened. Such a rotation of the door handle 12 is, for example, in the schematic perspective view according to FIG. 3 shown. The rotation of the door handle 12 about the axis of rotation is in FIG. 3 thereby illustrated by the arrow 56. The electrically controllable coupling 28 can be activated, for example, by means of a transponder, so that authorized persons can close the coupling 28 with this transponder and can then open a door by actuating the door handle 12. Otherwise, the electrically controllable clutch 28 remains in the open state, so that no power transmission from the door handle 12 to the latch 60 is possible and accordingly the door can not be opened by operation or rotation of the door handle 12.

Usually, in the case of door lever fastening devices, a restoring force is provided by the latch 60 of the door lock or the door lock itself. As a result, a door handle is automatically adjusted to the end of an operation in a neutral position. Due to the electrically controllable coupling 28 and its normally open state, however, such a restoring force can no longer be made available at any time by the latch 60 or the door lock. For this reason, the bearing assembly 16 of the door handle mounting device 10 comprises a spring element 22, by means of which the bearing element 18 is rotatable relative to the guide member 20 automatically about the axis of rotation in a neutral position. The spring element 22 is particularly well in the schematic perspective view according to FIG. 2 to recognize in which parts of the door plate 14 are not shown for better recognition of the spring element 22. Both the FIG. 1 as well as the FIG. 2 show the neutral position of the door handle mounting device 10 and the door handle 12, while the FIG. 3 an actuated position of the door handle 12 shows. As in FIG. 3 can be seen, the spring element 22 is compressed during the actuation of the door handle 12, so that, accordingly, a restoring spring force is generated. After releasing the door handle 12, therefore, both the door handle 12 and the bearing member 18 automatically returns to the neutral position.

With respect to the guide member 20, the bearing member 18 is secured in the direction of the side of the door handle 12 against axial movement on one side by a stop and / or the door handle 12. In order to pull out the bearing element 18 from the guide member 20 in the direction of the door handle 12 (ie in the reverse direction) In addition, an axial securing for fixing an axial position of the bearing element 18 relative to the guide element 20 is provided. Furthermore, a driver is provided by means of which a restoring force of the spring element 22 for rotating the bearing element 18 in the neutral position of the spring element 22 on the bearing element 18 is transferable. In the door handle mounting device 10, both the driver and the axial fuse are integrally formed as Sicherungsmitnehmerelement 24, which is arranged with respect to the door plate 14 and the guide member 20 on the same side as the connecting element 66. Thus, the door handle mounting device 10 has very few parts and is constructively simple.

The Sicherungsmitnehmerelement 24 is substantially formed as a flat clip element, which is inserted on a part of the bearing element 18. By corresponding projections 26 on the bearing element 18 while the Sicherungsmitnehmerelement 24 is secured against rotation relative to the bearing member 18 against rotation about the rotational axis. Accordingly, the Sicherungsmitnehmerelement 24 is arranged in a groove on the bearing element 18 in the direction of the door handle 12 in front of the guide element 20 and behind the connecting element 66.

The Sicherungsmitnehmerelement 24 can be made for example by a punching and deep drawing process of a metallic sheet. The basic shape of the securing cam member 24 may be punched out while forming two protrusions 30 by a deep-drawing process. The projections 30 each form a contact surface for the spring element 22, as in FIG. 2 can be seen. The spring element 22 is designed, for example, as a helical spring, which acts as a compression spring here and has an end plate element 32 at its respective ends. The end plate member 32 forms a secure contact surface for the two projections 30 of the Sicherungsmitnehmerelements 24 and each held in the last spirals of the spring element 22 plastic parts.

As in particular in FIG. 3 can be seen, lifts one of the protrusions 30 of the spring element 22 upon rotation of the door handle 12 and a corresponding rotation of both the bearing member 18 and the Sicherungsmitnehmerelements 24, while another projection 30 supports it, compressing the spring element 22. The side of the spring element 22, on which the projection 30 lifts off, rests against a stop element 34 of the door plate 14, as shown in FIG FIG. 1 can be seen. Accordingly, the spring force of the spring element 22 can then be introduced into the door leaf 58 of the door plate 14.

For a particularly cost-effective tolerance compensation 34 compensating plates 36 are provided in each case at the stop elements, which are particularly well in FIG. 2 can be seen. These balancing plates 36 can be inserted through respective passage openings 38 between respective ends of the spring element 22 and the stop elements 34, even if the remaining door handle mounting device 10 and in particular parts of the door plate 14 are already mounted. Thereby, respective parts of the door handle mounting device 10 can be produced with low manufacturing accuracies, without causing an undesirably high clearance in the door handle mounting device 10 and / or the neutral position deviates from a horizontal orientation of the Türdrückers12. By means of the balancing plates 36 also the neutral position can be adjusted by itself. The abutment members 34 mutually support one end of the spring member 22 when the bearing member 18 is rotated about the rotation axis relative to the guide member 20. The compensation elements or compensating plates 36 are thus arranged on a spring-side surface of the stop elements 34.

The spring element 22 is held on the door plate 14 at a distance from the axis of rotation in an arcuate path, wherein the spring element 22 exerts on the bearing element 18 at least in the neutral position an additional biasing force which acts substantially transversely to the axis of rotation. This preload force is in FIG. 2 marked with the thick arrow 54. By this biasing force, any play between the guide member 20 and the bearing member 18 transverse to the axis of rotation, in particular in the neutral position, be compensated. The bearing element 18 is pressed by the biasing force on one side of the guide member 20, preferably according to an actuating direction. When pressed on the door handle 12 - in FIG. 2 So from below - then the bearing element 18 is already on, so that the door handle mounting device 10 feels free of play for the user. This creates a particularly high-quality impression.

Due to the two-sided provided projections 30 of the Sicherungsmitnehmerelements 24, a bidirectional rotation of the bearing member 18 relative to the guide member 20 from the neutral position can be allowed in the door handle mounting device 10, in each case then a restoring spring force can be provided in both directions. As a result, the door handle fixing device 10 can be used on both sides on a door leaf 58. The door handle mounting device 10 is thus suitable for both a left and a right mounting. Alternatively, one of the directions of rotation may be used to open a latch 60 and another direction of rotation for another function, such as latching the door latch. Likewise, both directions of rotation can only cause an opening of the case 60 or, for example, the upward rotation have no function.

Characterized in that the Sicherungsmitnehmerelement 24 is arranged with respect to the door plate 14 on the same side as the connecting element 66, the Sicherungsmitnehmerelement 24 is in the mounted on the door panel 58 position of the door handle mounting device 10 facing the door leaf 58 and simultaneously covered by the door plate 14. This allows the Sicherungsmitnehmerelement 24 are particularly well protected against tampering by unauthorized persons. In particular, for example, the door plate 14 can be fastened by a side of the door leaf 58 facing away from the door lever fastening device 10, for example by respective screws passing through the door leaf 58. Accordingly, these screws can be solved nondestructively only when access has already been obtained through the door. Otherwise, for example, the door plate 14 could be disassembled even with the door still closed and the Sicherungsmitnehmerelement 24 are released, so that the bearing element 18 can be removed, as well as the axial securing is solved. In this case, it may thus be possible for an unauthorized person to gain access to the electrically controllable coupling 28 with less effort and potentially manipulate it. This is so here due to the construction of the door handle mounting device 10 prevented.

On the guide element 20, two stopper elements 40 are arranged, which in particular in FIG. 2 are clearly visible. By means of these stopper elements 40, a maximum angle of rotation of the bearing element 18 can be limited with respect to the neutral position. The Stopper elements 40 occur at a maximum angle of rotation with corresponding projections 42 of the Sicherungsmitnehmerelements 24 into engagement. Thereby, a defined end position for an actuation of the door handle 12 can be specified, which can also be referred to as a door handle. In addition, an overload of respective parts of the door handle mounting device 10, for example, the spring element 22 can be avoided. Respective loads can be introduced into the guide member 20 directly on the Sicherungsmitnehmerelement 24 and the stopper elements 40 upon reaching the maximum angle of rotation. Thus, respective abusive loads, for example, when resting on the door handle 12, can be safely absorbed by the door handle mounting device 10. The loads can be absorbed in particular without an introduction of force in a lock case. So it may also be possible to dispense with additional structural reinforcements.

The stopper elements 40 in this case have a pin-shaped region which can be inserted through respective bores of the guide element 20. On the back, as can be seen in particular in the schematic perspective view according to FIG, the Sopperelemente 40 thereby have a widened base. As a result, slippage of the stopper elements 40 is prevented by the guide member 20. Slipping out against the insertion direction is prevented after assembly by an outer door shield part.

In FIG. 3 it can be seen in particular how the corresponding projection 42 of the Sicherungsmitnehmerelements 24 comes into abutment with the stopper member 40 at maximum rotation of the door handle 12 in one direction.

In FIG. 1 Furthermore, it can be seen that both the stop elements 34 and the compensating plates 36 have an elongate passage opening 44 through which at least a portion of the Sicherungsmitnehmerelements 24 - here the projections 30 - can be passed during rotation about the axis of rotation. The passage openings 44 may be formed in particular groove-shaped. Due to the passage openings 44, the projections 30 can come into contact with the respective end of the spring element 22 upon rotation of the bearing element 18 or release the contact with the respective end of the spring element 22. As a result, the construction of the door handle fixing device 10 can be particularly compact. In particular, the extent along the axis of rotation can thus be particularly short.

The Sicherungsmitnehmerelement 24 is disposed adjacent to the guide member 20 along the axis of rotation. As a result, the securing driver element 24 is protected against tilting and can provide a further bearing surface for the bearing element 18. As a result, the bearing element 18 is supported particularly well against tilting, so that it rotates smoothly and the risk of tilting is reduced.

The door plate 14 is in this case constructed in several parts. The door plate 14 comprises an outer door plate part and an inner door plate part 46. Only in FIG. 5 is the outer door shield part and thus the total mounted door plate 14 is shown. In the other figures, the outer door shield part is not shown. The inner door plate part 46 has two inner door plate elements 48, wherein the two inner door plate elements 48 together have a receiving area for receiving the guide element 20 and the spring element 22. As in FIG. 1 can be seen, the two door plate elements 48 are substantially formed as half shells, which are attached to the guide member 20 from the outside transversely to the axis of rotation. Thereby, a receiving space is formed, in which the spring element 22 is securely held. An additional fixation of the spring element 22 can be dispensed with. The outer door shield part can then simply be placed on the two inner door plate elements 48 and the inner door plate part 46, so as to prevent a release of the inner door plate elements 48. The outer door shield part can then for example be easily bolted to the guide member 20 so as to securely connect all parts together. The spring element 22 can thereby press the inner door plate elements 48 radially against the outer door plate part, so that they are kept substantially free of play. This can for example offer advantages in terms of necessary manufacturing tolerances for the inner door plate part 46. The two door plate elements 48 are thus pressed by the spring element 22 slightly outwardly away from the axis of rotation of the bearing element 18. As a result, the two door plate elements 48 are braced against an inner side of the outer door plate part. As a result, therefore, a simple and cost-effective tolerance compensation done. Overall, the construction of the door handle mounting device 10 is compact and requires only a minimum number of screw connections. As a result, manufacturing and assembly costs are particularly low.

The door handle fixing device 10 is adapted to be fixed to a lock box mounted in the door leaf 58. Alternatively, the door handle mounting device 10 may also be attached directly to the door panel 58.

As in FIG. 6 can still be seen, the bearing element 18 on the inside a channel 68. This channel 68 is designed in the manner of a blind hole and has only one access opening 70 on the side of the connecting element 66. In the channel 68, a spring, not shown, for holding a fixing element is arranged in a locking position. By means of the fixing element, the door handle 12 can be fixed to the fastening element of the bearing element 18. The fixing element may, for example, be designed in the shape of a peg and engage or latch into a corresponding receiving opening of the door handle 12. As a result, the door handle 12 is secured against being pulled down by the fastening element of the bearing element 18 along the axis of rotation. It is therefore an axial securing of the door handle 12. The fixing element can be released from the locking position by being pressed onto the spring element in the channel 68. As a result, the fixing element is then moved from the locking position to a release position. Only then can the door handle 12 be removed from the bearing element 18. Since the channel 68 is accessible only from the side, which faces the door leaf 58 in the installed state, the door handle fastening device 10 is additionally protected against manipulation. In particular, this provides a further safeguard against disassembly of the door handle mounting device 10 by persons who do not have appropriate access. As a result, the door handle fixing device 10 is particularly safe.

The axial boundary or an axial stop 52 of the bearing element 18 is in the FIG. 4 to recognize which schematically the door handle mounting device 10 according to FIG. 2 from a mounted in the mounted position the door leaf 58 side. This stop 52 prevents the bearing element 18 from being pulled through by the guide element 20 FIG. 4 In addition, a door handle side portion of the bearing element 18 can be seen, to which the door handle 12 is attached.

FIG. 5 shows an additional cover 62 of the door handle mounting device 10. Behind this cover 62, for example, batteries and electronic components for driving the electric coupling 28 and the supply of power are arranged. So these parts are easily accessible, without the need for this Door handle attachment device 10 must be disassembled. In this case, even with such maintenance no unauthorized access to the clutch 28 itself can be obtained.
