Description

The invention relates to a door handle fastening device for attaching a door handle to a door leaf. Furthermore, the invention relates to a door lock with such a door handle fastening device.

Doors are usually equipped with a door handle, which can be designed, for example, as a door handle, in order to be able to open the door. For example, in order to open the door, the door handle is rotated downward about an axis of rotation in order to thereby release a latch of a corresponding door lock. The lever handle must be stored on the door leaf so that it can be operated. In modern locking systems, in particular locking systems for commercially used objects, an electrically controllable coupling can be provided between the door handle and a corresponding latch of the door lock. The coupling can be activated, for example, by means of a transponder, so that only authorized persons can open the door and have the appropriate access. Accordingly, the door handle is only connected to the latch of the door lock when the electrical clutch is closed. A spring of the latch can therefore not always provide a restoring force for the door handle after it has been actuated. For this reason, a corresponding reset mechanism for moving the door handle to a neutral position is usually additionally provided, which keeps the door handle in the neutral position even in the decoupled state. Such a reset mechanism can include a spring element, for example.

From the DE 20 2005 015 858 U1 is known a door fitting for mounting on a door leaf, which has a lower rosette for storing a door handle. Furthermore, the door fitting has a return mechanism for pushing up the door handle. The return mechanism 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 includes a detent spring for locking the Door handle, which serves as an axial lock. Overall, the door fitting described here requires a large number of different parts.

From the DE 37 10 883 A1 a door fitting with a door operating element and a door plate is known, in which a curved coil spring provides a corresponding restoring force in a neutral position. A movement of a door operating element described here is suitably limited by stops in the range of movement of a latch, so that the door fitting is unsuitable if a coupling is provided between the latch 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 spiral spring. A large installation space is required for a sufficiently high restoring force and, moreover, such a return spring unit can have a large play in a neutral position of a door handle.

DE 20 2013 100 325 U1 describes a handle mounting of a door or window handle.

GB 892 851 A describes a door handle.

The object of the present invention is to provide a structurally simple and safe door handle fastening device for attaching a door handle to a door leaf, which is suitable for being used together with an electrically controllable clutch. Furthermore, it is an object of the present invention to provide a structurally simple and secure door lock which is suitable for being used together with an electrically controllable clutch.

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

A first aspect of the invention relates to a door handle fastening device for attaching a door handle to a door leaf with at least one door plate and with a bearing arrangement. The bearing arrangement has a bearing element for rotatably mounting the lever handle about an axis of rotation, the axis of rotation being predetermined by a guide element of the bearing arrangement and the bearing element with respect to of the door plate has a fastening element for fastening the door handle on one side and a connecting element on an opposite side along the axis of rotation. 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 controllable coupling which, in the coupled state, allows a power transmission from the door handle to a latch of a door lock. Conversely, the power transmission can be opened in the uncoupled state, so that a latch of a door lock cannot be opened by means of the door handle.

Furthermore, the bearing arrangement preferably has an axial securing means 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 can be rotated automatically about the axis of rotation into a neutral position relative to the guide element. In this way, a correspondingly mounted door handle is automatically held in the neutral position even when the electrically controllable clutch is disengaged, or is adjusted back into this after the door handle or the bearing element has been rotated. At the same time, a certain actuation force is required in the decoupled state. A corresponding lever handle set has a high quality even when uncoupled, since it then does not feel loose or has excessive play. In addition, the bearing arrangement preferably comprises a driver, by means of which a restoring force of the spring element for rotating the bearing element into the neutral position can be transmitted from the spring element to the bearing element. The driver and the axial securing device are preferably formed in one piece as a securing driver element, which is preferably arranged on the same side with respect to the door plate as the connecting element.

In the door handle fastening device, preferably both the axial securing function and the driver or force transmission function are provided by a single component, the securing driver element. As a result, the door handle fastening device preferably requires a particularly small number of parts, which makes it structurally simple. Overall, manufacturing and assembly costs can be reduced. By preferably arranging the securing driver element on the same side with respect to the door plate as the connecting element for connecting to the electrically controllable coupling can also increase the robustness of the door handle fastening device against unwanted manipulations. Accordingly, the door handle fastening device can be particularly secure.

With such an arrangement, the securing driver element is in the installed state of the door handle fastening device preferably on a side of the door plate facing the door leaf. As a result, the securing driver element can 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 fastening device is arranged on the door plate. In general, this page can also be accessed by unauthorized persons. Unauthorized persons can, for example, be persons without a transponder to open the door. Due to the arrangement of the securing driver element described, this can only be removed from the bearing element, for example, when the door plate is removed. Only then is it possible to dismantle the door handle fastening device without destroying it, in particular removing the bearing element from the guide element. The door handle fastening device can be designed so that the coupling is only accessible from the access side after the bearing element has been removed. The door sign can in particular be mounted in such a way that it can only be detached if access to a room locked by the corresponding door has already been made possible. The door plate can therefore be mounted, for example, in such a way that disassembly is only possible from a side of the door panel facing away from the access side. This means that the electrically controllable coupling must first be closed, then the door must be opened, and only then is it possible to remove the securing driver element without destroying the lever handle fastening device. Accordingly, it can be seen how the arrangement of the securing driver element can increase security.

The spring element can be mounted on the door handle fastening device, in particular on the door plate and / or the guide element. The door plate can also be designed as a guide element in order to further reduce the number of parts required. The securing driver element can be designed as an essentially flat and / or disc-shaped element, in particular as a securing ring with one or two contact areas for one or both ends of the spring element. In particular, it can Securing driver element thus have two spaced apart support areas. The securing driver element can be manufactured particularly inexpensively, in particular in a stamping and / or deep-drawing process. The basic shape can be punched out of sheet metal and, in particular, protruding support areas can be introduced during deep drawing.

The axial securing of the securing driver element defines the position of the bearing element relative to the guide element along the axis of rotation; in particular, axial displacement of the bearing element can thus 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 can have a stop, by means of which the axial movement of the bearing element relative to the guide element is limited in the other direction along the axis of rotation. This axial securing in the form of the stop can be formed, for example, in one piece 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. A permanent and permanent connection of the stop to the bearing element can increase security, since removal of the bearing element is only possible by destructive disassembly or disassembly of the securing driver element. The securing driver element can, for example, be pushed onto the bearing element for assembly after it has been inserted into the guide element up to the stop. The bearing element can, for example, have a corresponding groove in which the securing driver element engages.

Advantageously, the securing driver element can also form part of the bearing of the bearing element, in particular together with the guide element. For example, the securing driver element can absorb bending forces together with the guide element, which can be introduced into the bearing element, for example, by resting on the lever handle. For example, the securing driver element can rest on the guide element with a surface transverse, in particular at right angles to the axis of rotation.

The guide element can be part of the door plate or can also be formed by the door plate itself. This means that very few parts are required. For example, that Door plate can also be a rosette of a lever handle set. The door handle fastening device can be attached directly to the door leaf, but also indirectly by means of further parts, for example a door lock and / or a latch of the door.

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

The connecting element can be permanently connected to 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 also only engage with the coupling, for example in a form-fitting manner when the coupling is closed. Such a door lock can be particularly robust against manipulation of the coupling and thus unauthorized opening of the lock.

The securing driver element is preferably secured against rotation around the bearing element along the axis of rotation in order to be able to transmit forces accordingly. Such a fuse can be designed, for example, as an inexpensive form fit.

The axis of rotation can be predetermined, for example, by a through opening in the guide element. The guide element can for example be designed as a bearing plate. Alternatively or additionally, the guide element can 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 mounting the bearing element. The guide element, in particular parts thereof, can be attached to the door plate. In particular, the door plate can comprise a two-part inner door plate, whereby the Door handle fastening device can be installed particularly easily. The guide element can be clamped between these two inner door plate elements, for example in a groove, so that additional fixing elements can be dispensed with. Alternatively, the door plate itself can also form the guide element.

In a further advantageous embodiment of the door handle fastening device, it is provided that the spring element is held on the door plate at a distance from the axis of rotation in an arcuate path and is connected to the bearing element by means of the securing driver element at its two ends for power transmission, the spring element preferably being at least on the bearing element in the neutral position exerts an additional prestressing force which acts essentially transversely to the axis of rotation. The spring element can be an inexpensive standard component and enables space-saving, high restoring forces to hold the lever handle securely in the neutral position. This can give the door handle fastening device a particularly high-quality feel.

The spring element can, for example, rest against a surface transverse to the axis of rotation, in particular at right angles to the axis of rotation of the securing driver element, the guide element and / or the door plate. By means of the securing driver element, a force of the spring element, which acts rotationally about the axis of rotation, 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.

The prestressing force in the installed position preferably acts essentially vertically downward on the bearing element. When the pretensioning force is removed or a change in the pretensioning force, a typical door lever operation pushes the bearing element further in the same direction. As a result, the door handle fastening device has a particularly small amount of play. If, for example, a person presses the lever handle to open a door, the bearing element is already preloaded in this direction and rests there on the corresponding bearing. As a result, the actuator can no longer feel any play in a vertical direction when turning the lever handle. Correspondingly, parts of the door handle fastening device, in particular the bearing element and / or the guide element, can also be manufactured with less strict manufacturing tolerances. The spring element is preferably designed as a helical spring, which can provide high restoring forces in a space-saving manner. In particular, use as a compression spring makes sense, since the spring element can be particularly resistant to permanent deformation. Corresponding restoring forces arise from compression and / or expansion of the spring element when the bearing element rotates, which at the same time also causes the securing driver element to rotate and thus deform the spring element.

The longitudinal extension of the spring element preferably follows the arcuate path. The door plate can accordingly have an arcuate receiving area for the spring element. An arc can 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 also be able to turn the door handle element together with the bearing arrangement or the bearing element into the neutral position when no external forces are acting. With a corresponding design of the spring element, a respective weight of a door handle element can also be taken into account. In particular, a square pin element of the bearing arrangement can be turned automatically into the neutral position by means of the spring element.

Over the entire length of the spring, the spring element can be at a constant distance from it, in particular at right angles to the axis of rotation. The bearing arrangement can be designed, for example, as a radial bearing, which only allows the bearing element to be rotated relative to the guide element along the axis of rotation and blocks axial movement.

An actuation of the door handle can mean in particular a rotation of the bearing element about the axis of rotation. After an actuation has ended, the bearing element and thus a door handle attached to it can automatically turn back into the neutral position. By means of the bearing arrangement, a door handle can thus be rotatably attached to a door leaf via the door plate, wherein the door handle can be connected to the latch of the door lock by means of the coupling. The door plate can also be designed as a fitting. The door fitting can be defined as a door plate plus lever handle. The bearing arrangement can be designed, for example, as a ball bearing or plain bearing, in which also part of the door handle can be rotatably mounted. In addition to the bearing element, the door handle can also be guided on the guide element. Optionally, the door handle can also be connected to a bolt by the coupling, which can then also be operated with the door handle. This can be expedient in particular in the case of a door handle fastening device designed to be bidirectionally rotatable.

When the door closes, the latch can automatically snap into a corresponding recess in a door frame because of a beveled side. This will keep the door in the closed position. By actuating the door handle with the clutch closed, the latch pulls out of the corresponding holding element or the corresponding recess in 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 handle fastening device, it is provided that the bearing arrangement is designed to allow bidirectional rotation of the bearing element relative to the guide element from the neutral position. This makes it possible, for example, to fasten the lever handle in different positions. As a result, the door handle fastening device can be used for both sides of a door without having to be changed in terms of construction. Accordingly, a high degree of standardization and identical parts can be achieved. The door handle fastening device can thus be suitable for the fact that door handles can be attached to it in at least two different positions. As a result, the door handle fastening device is suitable for both left and right mounting.

Alternatively or additionally, there can be two different actuation options with corresponding actuation functions. For example, a latch can be opened by pressing the lever handle down. When turning in the other direction, for example pulling up the door handle instead of pressing it down, an additional function of the door lock can be actuated. For example, the door lock can be locked by pulling up the door handle.

In a further advantageous embodiment of the door handle fastening device, it is provided that at least one stop element is arranged on the guide element, by means of which a maximum angle of rotation of the bearing element with respect to the neutral position is limited, the at least one stop element preferably being designed to engage the securing driver element at the maximum angle of rotation. In a bearing arrangement designed for bidirectional rotation, the door handle fastening device preferably comprises two stop elements in order to limit the maximum angle of rotation in both directions of rotation. Overall, a defined end position can be specified when the door handle is actuated, which creates a particularly high-quality operating impression. In addition, particularly high abusive actuation forces can be absorbed by the door handle fastening device. This includes, for example, leaning on or climbing on the door handle. The stop elements can, for example, be designed as stop elements and / or introduce forces directly into the door plate and / or the guide element when the maximum angle of rotation is reached.

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

In a further advantageous embodiment of the door handle fastening device, a compensating element is arranged on at least one of the stop elements on a spring-side surface. By means of this compensation element, a rotational play can be compensated, in particular after the remaining door handle fastening device has been installed. For example, the compensation element can be designed as a plate, compensation plate, compensation plate or washer. As a result, manufacturing tolerances can be compensated for by the smallest twist of the Bearing element, the spring element comes into direct contact at one end with the stop element or the compensating element arranged thereon and lifts off the securing driver element. The spring element therefore comes into contact only with the smallest rotations at one end exclusively with a contact area of the securing driver element. As a result, the feel of the door handle fastening device is particularly valuable, since there is no or only a particularly small, loosely rotating area around the neutral position. Rotating loosely means that no restoring force has yet been built up. A number of compensating elements of different thicknesses can be provided for assembly or in production in order to enable compensation, depending on the existing tolerance.

The compensating element can advantageously also have at least one projection for fixing the guide element to the door plate. The compensating element can thus also be used to fasten a door plate to the guide element, in particular a multi-part door plate.

The door plate can have at least one access opening through which a respective one of the compensating elements can be inserted into a position between the stop element and the spring element in the already partially assembled state. This makes assembly particularly easy and quick. In particular, the compensation element can be easily exchanged according to the trial-and-error principle until its necessary thickness has been determined. As a result, complex measuring methods for selecting a suitable compensating element can be avoided.

In a further advantageous embodiment of the door handle fastening 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 area of the securing driver element is guided during rotation about the axis of rotation, in order to rotate with the support area when the bearing element rotates To come into contact with the respective end of the spring element or to release 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. With such a through opening, the door handle fastening device can be particularly compact. In particular, the respective stop element, compensating elements and the securing driver element in the To be arranged essentially in the same axial area along the axis of rotation in the door handle fastening device, without these interfering with one another and / or being able to collide with one another during corresponding rotations about the axis of rotation.

In a further advantageous embodiment of the door handle fastening device, it is provided that the spring element is designed as a compression spring; and in particular the compression spring has an end plate element at each of its ends. In particular, the compression spring can be designed as a helical spring. A high restoring force can be generated in a space-saving manner with a compression spring. The end plate elements are preferably held in the respective last spring winding of the helical spring. The end plate elements can serve as an additional guide and / or system for a contact area of the securing driver element. This ensures a particularly safe power transmission. The end plate elements can for example consist of a plastic. The end plate elements can be positively inserted and / or rest on one end of the helical spring.

In a further advantageous embodiment of the door handle fastening device, it is provided that the securing driver element is positively secured against rotation on the bearing element; wherein the securing driver element is designed in particular as a clip element which comprises the bearing element at least in some areas. The positive rotation lock is particularly compact and inexpensive. In particular, additional fastening parts can be dispensed with. Training as a clip element enables particularly simple and quick assembly and / or disassembly of the securing driver element. For example, the securing driver element can be designed as an essentially 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 fastening device, it is provided that the securing driver element is arranged adjacent to the guide element along the axis of rotation, preferably adjacent to it. As a result, the lever handle fastening device has particularly small rocker arm arms. So the door handle fastening device can still be very robust with low material thicknesses. In particular, the guide element and / or the door plate can be made particularly thin-walled. The securing driver element can also additionally support these parts by directly adjoining or resting on them and / or can also serve as part of the mounting of the bearing element.

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

A two-part inner door plate enables the guide element to be received particularly securely by inserting it into a receiving area and holding it in a form-fitting manner. The outer door plate can, for example, be at least partially placed over the two inner door plate elements in order to hold them in this way. At the same time, an interior protected from external access can be formed in the manner of a housing. The outer door plate can, for example, be screwed tightly to the two inner door plate elements for security purposes. The outer door plate can have a positive receiving area for the two inner door plate elements. In addition, the spring element can also brace the two inner door plate elements against the outer door plate. This enables additional tolerance compensation. Tolerance compensation allows parts with lower demands on their Manufacturing tolerances are used, whereby the manufacturing costs can be particularly low.

In a further advantageous embodiment of the door handle fastening device, it is provided that the door handle fastening device is designed to be fastened to a lock case mounted in the door leaf; in particular by means of a fastening device of the door handle 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 fastening points on the door lock case can be made available. The fastening device is preferably arranged on the door plate and / or a part thereof. The respective fixing elements can be designed, for example, in the form of a pin. The tolerance compensation of the distance between two corresponding fastening holes in the lock case can preferably be carried out in the vertical direction in the installed position. The fastening device preferably comprises, for example, two immovable pin elements and two movable pin elements, which are held together on a sliding body which is guided in two grooves and / or cutouts in the door plate. The sliding body can be designed in such a way that it can also be tilted easily in the respective grooves, thereby providing a further tolerance compensation. For this purpose, the sliding body can be held in the grooves with play, for example.

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

In a further advantageous embodiment of the door handle fastening device, it is provided that the door handle fastening device comprises the electrically controllable coupling, by means of which, in the coupled state, a torque can be transmitted when the door lever is actuated to a latch of a door lock to open it, and by means of which, when uncoupled, no torque is transmitted the actuation of the door handle is transferable to the latch to open it. When the door handle fastening device is installed on a door, the bearing element is mechanically connected to the latch in the coupled (closed) state and in the decoupled (Open) state disconnected, so that forces can be transmitted from the door handle or not transmitted.

The clutch can be actuated electronically, 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 makes it easy to retrofit doors. Alternatively, the coupling can also be connected to a power supply system in the house. Likewise, the door handle fastening device and / or the electrically controllable coupling can comprise respective electronics and / or motors. A radio receiver can be provided in order to be able to control the clutch wirelessly. Corresponding radio actuation of the coupling can take place, for example, using active and / or passive transponders. The electronically controllable clutch or door handle fastening device can also include an RFID reader and / or an input device for entering a pin code for the control thereof. Generally, a variety of access control mechanisms can be used in conjunction with the electronically controllable clutch and the door handle fastening device.

Preferably, all of the components which enable the door handle to transmit power from the latch are concealed at least behind the door plate, in particular the outer door plate. As a result, the door handle fastening device is particularly protected against manipulation for unauthorized opening of the appropriately equipped door. However, some components, such as batteries, can also be arranged outside the door plate, preferably behind a separate cover. As a result, the respective batteries can be replaced quickly and easily, for example, without having to dismantle the door handle fastening device itself and / or without increasing the risk of unauthorized access.

In a further advantageous embodiment of the door handle fastening device, it is provided that the fastening element of the bearing element has at least one fixing element on the outside, by means of which the door handle can be fixed to the fastening element, the fixing element being held in a locking position by means of a spring, in which the one arranged on the fastening element Door handle is attached to it. For example, an additional, movable cylinder can be provided on the fastening element, which cylinder is located in a corresponding recess in an assembly opening the lever handle can snap into place. As a result, the door handle is axially fixed to the fastening element along the axis of rotation.

In a further advantageous embodiment of the door handle fastening device, it is provided that the bearing element has an internal 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, with a force being exerted on the spring in the channel, in particular a push, an adjustment of the fixing element can be released from the locking position into a release position. In particular, when the fixing element is coupled to the spring element, it can be adjusted directly into the release position by exerting force on the spring. As an alternative or in addition, the force of gravity can also be used to adjust to the release position when the spring is pressed down instead of a connection between the spring and the fixing element. A connection between the spring and the fixing element, for example gluing or soldering, can thus be dispensed with. In the release position, the lever handle arranged on the fastening element is no longer axially fixed thereon and can be removed. For example, the door handle can then be removed from the fastening element by axially moving it along the axis of rotation or by pulling it off. The axial fixation described is particularly space-saving. By arranging the access opening on the side of the connecting element, the door handle can only be removed from the door handle fastening device if the door handle fastening device is removed from the door leaf. As a result, the door handle fastening device is particularly secured against unwanted manipulation. In particular, the door handle can also block the outer door plate part from being pulled off other parts of the door handle fastening device in the fixed state.

A further aspect of the invention relates to a door handle fastening device with at least one door plate for fastening a door handle to a door leaf and with a bearing arrangement, the bearing arrangement comprising a bearing element for rotatably mounting 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 has a fastening element for fastening the door handle on one side and a connecting element on an opposite side along the axis of rotation, which is designed to be connected to an electrically controllable coupling which is 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 at least one fixing element on the outside, by means of which the door handle can be fixed to the fastening element, the fixing element being held in a locking position by means of a spring, in which the door handle arranged on the fastening element is fixed thereon. This fixation offers the advantages already described above and can protect the corresponding door handle fastening device against unwanted manipulation. The door handle fastening device can also include a door handle and can be referred to as a handle set.

A second aspect of the invention relates to a door lock with a door handle fastening device according to the first aspect of the invention and a lock case which is designed to be fastened in and / or to a door leaf and which has a latch for holding a door in a closed state on one Corresponding holding element of a door frame, wherein the door handle fastening device is designed to transmit a force and / or a torque from a door handle to the latch for releasing the door from the closed state. The door handle can also be part of the door lock. The corresponding holding element of the door frame can for example be a recess in the door frame.

The features and advantages which result from the door handle fastening device according to the first aspect of the invention can be found in the description of the first aspect of the invention, advantageous configurations of the first aspect of the invention being regarded as advantageous configurations of the second aspect of the invention and vice versa. The other features and advantages for the other aspects mentioned here also result from the descriptions of the other aspects of the invention, advantageous configurations of the other aspects of the invention also being considered as configurations of the first and / or second aspect.

Figure 1 shows a schematic perspective view of a door handle fastening device 10 for attaching a door handle 12 to a door leaf 58. The assembled state is in the schematic perspective view of FIG Figure 5 shown. The door handle 12 is designed as a door handle. The door handle fastening device 10 comprises a door plate 14 and a bearing arrangement 16. In Figure 1 only parts of the door plate 14 are shown - a fully assembled illustration is shown in FIG Figure 5 shown. The bearing arrangement 16 has a bearing element 18, on which the door handle 12 is rotatably mounted about an axis of rotation and which is partially covered by the coupling 28 attached to it. The axis of rotation is predetermined by a guide element 20, which is designed here as a metallic plate. The bearing element 18 is rotatably mounted in a through opening of the guide element 20. The bearing element 18 has a connecting element 66 on a side facing away from the door handle 12, which is designed to be connected to the electrically controllable clutch 28 mounted thereon and covering it. The connecting element 66 is in Fig. 6 can be seen since the coupling 28 attached to it is not shown here. The connecting element 66 represents a receptacle for the clutch 28 and can form a receptacle space corresponding to the clutch 28. The connecting element 66 can also be referred to as part of a handle flange. As in the Figures 1 to 4 It can be seen that the coupling 28 has a receiving opening 50, which in the present case is designed to receive a regular pusher pin of a latch 60 or a door lock. This area of the coupling 28 can also be referred to as a coupling adapter for the square or coupling ring. On the other hand, on the side facing the door handle 12, the bearing element 18 has a fastening element onto which the door handle 12 is attached. In the figures, the fastening element is essentially covered by the attached door handle 12. The sides of the bearing element 18 can be defined with respect to the guide element 20 and / or the door plate 14. The fastening element can in particular be a square pin, which allows standardized fastening of a corresponding lever handle.

The electrically controllable clutch 28 permits electronic access control with the door handle fastening device 10. In the present case, the clutch 28 comprises the clutch pin 64, which can be moved radially by means of an electric actuator. In the radially extended state, a positive connection for force transmission with the bearing element 18 is produced, as is shown in FIGS Figures 1 to 4 is shown. The coupling pin 64 is inserted into a recess in the bearing element 18 or the connecting element 66. The clutch is then in the coupled state. The coupling pin 64 can be moved radially inwards for coupling and radially outwards for decoupling. 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 Figure 5 shown. By turning the lever handle 12 by the Guide element 20 predetermined axis of rotation can then be pulled according to the latch 60 from a door frame 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 Figure 3 shown. The rotation of the door handle 12 about the axis of rotation is in Figure 3 illustrated by arrow 56. The electrically controllable clutch 28 can be activated, for example, by means of a transponder, so that persons authorized to access can use this transponder to close the clutch 28 and 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 cannot be opened by actuating or rotating the door handle 12.

In door handle fastening devices, a restoring force is usually provided by the latch 60 of the door lock or the door lock itself. As a result, a lever handle is automatically set to a neutral position after an operation has ended. Due to the electrically controllable clutch 28 and its normally open state, however, such a resetting force can no longer be made available at any time by the latch 60 or the door lock. For this reason, the bearing arrangement 16 of the door handle fastening device 10 comprises a spring element 22, by means of which the bearing element 18 can be rotated automatically about the axis of rotation into a neutral position relative to the guide element 20. The spring element 22 is particularly good in the schematic perspective view according to FIG Figure 2 to recognize in which parts of the door plate 14 are not shown for better visibility of the spring element 22. Both the Figure 1 as well as the Figure 2 show the neutral position of the door handle fastening device 10 or the door handle 12, while the Figure 3 shows an actuated position of the door handle 12. Like doing in Figure 3 can be seen, the spring element 22 is compressed when the door handle 12 is actuated, so that a resetting spring force is generated accordingly. After releasing the door handle 12, both the door handle 12 and the bearing element 18 therefore automatically return to the neutral position.

With regard to the guide element 20, the bearing element 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. To pull the bearing element 18 out of the guide element 20 in the direction of the door handle 12 (ie in the opposite direction) prevent, an axial securing is additionally provided for fixing an axial position of the bearing element 18 relative to the guide element 20. Furthermore, a driver is provided, by means of which a restoring force of the spring element 22 for rotating the bearing element 18 into the neutral position can be transferred from the spring element 22 to the bearing element 18. In the door handle fastening device 10, both the driver and the axial securing device are formed in one piece as a safety driver element 24, which is arranged on the same side as the connecting element 66 with respect to the door plate 14 and the guide element 20. As a result, the door handle fastening device 10 has particularly few parts and is structurally simple.

The securing driver element 24 is essentially designed as a flat clip element which is inserted on part of the bearing element 18. By means of corresponding projections 26 on the bearing element 18, the securing driver element 24 is positively secured against rotation about the axis of rotation relative to the bearing element 18. The bearing element 18 and the securing driver element 24 accordingly rotate accordingly about the axis of rotation when the door handle 12 is actuated. Furthermore, the securing driver element 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 securing driver element 24 can be produced, for example, from a metal sheet by means of a stamping and deep-drawing process. The basic shape of the securing driver element 24 can be punched out, while two projections 30 are formed by a deep-drawing process. The projections 30 each form a contact surface for the spring element 22, as shown in FIG Figure 2 can be seen. The spring element 22 is designed, for example, as a helical spring, which functions here as a compression spring and has an end plate element 32 at its respective ends. The end plate element 32 forms a secure contact surface for the two projections 30 of the securing driver element 24 and are each plastic parts held in the last spirals of the spring element 22.

As especially in Figure 3 can be seen, one rotation of the door handle 12 and a corresponding rotation of both the bearing element 18 and the securing driver element 24 lifts one of the projections 30 from the spring element 22, while another projection 30 supports this, whereby the spring element 22 is compressed. The side of the spring element 22, on which the projection 30 lifts off, lies against a stop element 34 of the door plate 14, as shown in FIG Figure 1 can be seen. Accordingly, the spring force of the spring element 22 can then be introduced into the door leaf 58 from the door plate 14.

For particularly cost-effective tolerance compensation, compensation plates 36 are provided on the stop elements 34, which are particularly good at Figure 2 are recognizable. These compensation plates 36 can be inserted through respective through openings 38 between the respective ends of the spring element 22 and the stop elements 34, even if the remaining door handle fastening device 10 and in particular parts of the door plate 14 have already been installed. As a result, respective parts of the door handle fastening device 10 can be produced with low manufacturing accuracies without an undesirably high play in the door handle fastening device 10 and / or the neutral position deviating from a horizontal orientation of the door handle 12. The neutral position itself can also be adjusted by means of the compensating plates 36. The stop elements 34 mutually support one end of the spring element 22 when the bearing element 18 is rotated about the axis of rotation relative to the guide element 20. The compensating 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, the spring element 22 exerting an additional prestressing force on the bearing element 18, at least in the neutral position, which acts essentially transversely to the axis of rotation. This preload is in Figure 2 marked with the thick arrow 54. A possible play between the guide element 20 and the bearing element 18 transverse to the axis of rotation, in particular in the neutral position, can be compensated for by this prestressing force. The bearing element 18 is pressed on one side against the guide element 20 by the prestressing force, preferably in accordance with an actuation direction. When pressing the lever handle 12 - in Figure 2 So from below - the bearing element 18 is already in contact, so that the door handle fastening device 10 feels free of play for the user. This creates a particularly high quality impression.

Due to the projections 30 provided on both sides of the securing driver element 24, bidirectional rotation of the bearing element 18 relative to the guide element 20 from the neutral position can be permitted in the door handle fastening device 10, a resilient spring force then being able to be made available in both directions. As a result, the door handle fastening device 10 can be used on both sides of a door leaf 58. The door handle fastening device 10 is therefore suitable for both left and right mounting. Alternatively, one of the directions of rotation can be used to open a latch 60 and another direction of rotation for another function, such as, for example, locking the door lock. Likewise, both directions of rotation can only cause the latch 60 to open or, for example, the upward rotation have no function.

Because the securing driver element 24 is arranged on the same side as the connecting element 66 with respect to the door plate 14, the securing driver element 24 faces the door leaf 58 in the position of the door handle fastening device 10 mounted on the door leaf 58 and is simultaneously covered by the door plate 14. As a result, the securing driver element 24 can be particularly well protected against manipulation by unauthorized persons. In particular, for example, the door plate 14 can be fastened from a side of the door leaf 58 facing away from the door handle fastening device 10, for example by means of respective screws going through the door leaf 58. Accordingly, these screws can only be loosened non-destructively if access has already been gained through the door. Otherwise, for example, the door plate 14 could be removed even with the door still closed and the securing driver element 24 released, so that the bearing element 18 can be removed, since the axial securing means is also released in this way. In this case, it could therefore be possible for an unauthorized person to gain access to the electrically controllable clutch 28 with less effort and to potentially manipulate it. This is prevented here due to the design of the door handle fastening device 10.

Two stopper elements 40 are arranged on the guide element 20, which in particular in FIG Figure 2 are clearly visible. By means of these stopper elements 40, a maximum angle of rotation of the bearing element 18 with respect to the neutral position can be limited. The Stopper elements 40 engage with corresponding projections 42 of the securing driver element 24 at a maximum angle of rotation. As a result, a defined end position for actuating 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 fastening device 10, for example of the spring element 22, can be avoided. When the maximum angle of rotation is reached, respective loads can be introduced directly into the guide element 20 via the securing driver element 24 and the stopper elements 40. In this way, respective improper loads, for example when resting on the door handle 12, can be safely absorbed by the door handle fastening device 10. The loads can be accommodated in a lock case in particular without force being applied. It may also be possible to do without additional structural reinforcements.

The stopper elements 40 have a peg-shaped area, which can be inserted through respective bores in the guide element 20. On the back, as can be seen in particular in the schematic perspective view according to the figure, the sopper elements 40 have a widened base. This prevents the stopper elements 40 from slipping through the guide element 20. An outer door plate part prevents slipping out against the direction of insertion after installation.

In Figure 3 In particular, it can be seen how the corresponding projection 42 of the securing driver element 24 comes into contact with the stop element 40 when the door handle 12 is rotated in one direction.

In Figure 1 it can also be seen that both the stop elements 34 and the compensating plates 36 have an elongated through opening 44 through which at least a portion of the securing driver element 24 - here the projections 30 - can be passed during rotation about the axis of rotation. The through openings 44 can in particular be groove-shaped. Due to the through openings 44, the projections 30 can come into contact with the respective end of the spring element 22 when the bearing element 18 rotates, or can release the contact with the respective end of the spring element 22. As a result, the construction of the door handle fastening device 10 can be particularly compact. In particular, the extension along the axis of rotation can be particularly short.

The securing driver element 24 is arranged adjacent to the guide element 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 also particularly well supported against tilting, so that it rotates smoothly and the risk of tilting is reduced.

The door plate 14 is constructed here in several parts. The door plate 14 comprises an outer door plate part and an inner door plate part 46. Only in Figure 5 the outer door plate part and thus the overall mounted door plate 14 is shown. The outer door plate part is not shown in the other figures. The inner door plate part 46 has two inner door plate elements 48, the two inner door plate elements 48 together having a receiving area for receiving the guide element 20 and the spring element 22. As in Figure 1 It can be seen that the two door plate elements 48 are essentially designed as half-shells, which are attached to the guide element 20 from the outside transverse to the axis of rotation. This forms a receiving space in which the spring element 22 is held securely. An additional fixation of the spring element 22 can thus be dispensed with. The outer door plate part can then simply be plugged onto the two inner door plate elements 48 or the inner door plate part 46, in order to prevent the inner door plate elements 48 from becoming detached. The outer door plate part can then, for example, simply be screwed to the guide element 20 in order to securely connect all parts to one another. The spring element 22 can press the inner door plate elements 48 radially against the outer door plate part, so that they are kept essentially free of play. This can offer advantages with regard to the necessary manufacturing tolerances for the inner door plate part 46, for example. The two door plate elements 48 are thus pressed slightly outwards away from the axis of rotation of the bearing element 18 by the spring element 22. As a result, the two door plate elements 48 are braced against an inside of the outer door plate part. This allows a simple and inexpensive tolerance compensation. Overall, the construction of the door handle fastening device 10 is compact and requires only a minimal number of screw connections. As a result, manufacturing and assembly costs are particularly low.

The door handle fastening device 10 is designed to be fastened to a lock case mounted in the door leaf 58. Alternatively, the door handle fastening device 10 can also be fastened directly to the door leaf 58.

As in Figure 6 can also be seen, the bearing element 18 has a channel 68 on the inside. 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. A spring (not shown) for holding a fixing element in a locking position is arranged in the channel 68. The door handle 12 can be fixed to the fastening element of the bearing element 18 by means of the fixing element. The fixing element can, for example, be designed in the form of a pin and snap into or engage in a corresponding receiving opening in the door handle 12. As a result, the lever handle 12 is secured against pulling down from 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 pressing on the spring element in the channel 68. As a result, the fixing element is then moved from the locking position into a release position. Only then can the door handle 12 be removed from the bearing element 18. Since the channel 68 is only accessible from the side which, when installed, faces the door leaf 58, the lever handle fastening device 10 is additionally protected against manipulation. In particular, this represents a further safeguard against disassembly of the door handle fastening device 10 by persons who do not have appropriate access. As a result, the door handle fastening device 10 is particularly secure.

The axial limitation or an axial stop 52 of the bearing element 18 is in the Figure 4 to recognize which schematically the door handle fastening device 10 according to Figure 2 from a side facing away from the door leaf 58 in the assembled position. This stop 52 prevents the bearing element 18 from being pulled through by the guide element 20. In Figure 4 can also be seen a portion of the bearing element 18 on the door handle side to which the door handle 12 is attached.

Figure 5 shows an additional cover 62 of the door handle fastening device 10. Behind this cover 62, for example, batteries and electronic components for controlling the electrical clutch 28 and supplying it with electricity are arranged. So these parts are easily accessible without the need for this Door handle fastening device 10 must be dismantled. No unauthorized access to the clutch 28 itself can be obtained even with such maintenance.
