Description

[0001] The present invention relates to a door handle set for a door handle assembly for operating a door lock of a door, according to the preamble of claim 1. The invention further relates to a door handle assembly equipped with such a door handle set and to a method for mounting such a door handle set or such a door handle assembly on a door.

[0002] A generic door handle set is known from EP 2 182 144 B1 and comprises a door handle which has a polygonal recess for receiving a polygonal spindle, coaxial to a pivot axis of the door handle. The door handle set is also equipped with a cover cap which is rotatably and axially fixedly arranged on the door handle with respect to the pivot axis, and with a positioning plate which is rotatably and axially fixedly arranged on the door handle with respect to the pivot axis. Furthermore, a stop ring is provided which is rotationally fixed to the door handle with respect to the pivot axis and which has a first stop defining an unactuated initial position of the door handle in a circumferential direction relative to the pivot axis.Finally, the door handle set includes a mounting plate that can be fixed to the door in a rotationally fixed and axially fixed manner with respect to the pivot axis and that features a bayonet fitting recess and protrusion. In the known door handle set, the mounting plate has the protrusion of the bayonet fitting. The corresponding recess is formed on the positioning plate in the known door handle set. Furthermore, in the known door handle set, the positioning plate is rotationally fixed to the cover cap. The known door handle set also includes a spring that is supported circumferentially on the door handle and on the positioning plate with respect to the pivot axis, and which, particularly when the door handle set is mounted on a door, biases the door handle circumferentially into the unactuated starting position.

[0003] The standard door handle set can be installed relatively quickly, as it consists of a two-part assembly. The cover cap, positioning plate, spring, and stop ring are already mounted on the door handle, so the handle and these components form a mounting unit, representing the first part of the assembly. The mounting plate represents the second part of the assembly. To install the door handle set, the installer (male / female / diverse) must first mount the mounting plate to the door, aligning it coaxially with the spindle that has already been mounted on the door. The installer then places the mounting unit with the door handle onto the spindle, ensuring that the spindle engages axially in the spindle recess.To secure the door handle to the mounting plate, essentially joining the two parts of the assembly, the installer must align the positioning plate with the door handle so that the indentation and protrusion of the bayonet lock engage axially, allowing the bayonet lock to open. This requires rotating the positioning plate against the spring tension relative to the door handle, as the positioning plate is fixed to the cover cap. The installer must therefore rotate the cover cap relative to the door handle and then, with the indentation and protrusion of the bayonet lock aligned as desired, press the door handle firmly onto the multi-sided spindle. The installer can then release the cover cap. The spring will then return the positioning plate to its original position, thus locking the bayonet lock.At the same time, this also rotates the cover cap relative to the door handle. This results in a quick and easy installation of the door handle set.

[0004] However, it has been found that installing the familiar door handle set requires a comparatively high amount of force from the installer, as the cover cap must always be twisted against the spring's return force to create the open position of the bayonet lock. This involves rotating the positioning plate relative to the mounting plate so that the indentation and protrusion of the bayonet lock engage axially. The spring's return force is relatively strong to ensure a comfortable feel when the door handle set is installed. The user (male / female / diverse) can easily apply the torque required to turn or depress the door handle via the handle itself. A corresponding counter-torque is transmitted to the door via the mounting plate, which is firmly attached to the door, and supported by the door.During installation, the installer must manually apply the counter-torque required to rotate the cover cap relative to the door handle. Since the cover cap is relatively small, only a relatively short lever arm is available, resulting in a correspondingly large force that the installer must exert. When several dozen or even more than one hundred door handle sets need to be installed on a construction site, this is extremely strenuous and tiring for the installer.

[0005] A similar door handle set is also known from EP 2 840 203 A1.

[0006] From EP 1 683 933 B1, a clamping device is known with which a polygonal spindle can be secured in a polygonal receptacle of a door handle. Further clamping devices of this type are known from DE 10 2022 120 478 A1 and DE 10 2021 107 252 A1.

[0007] The present invention addresses the problem of providing an improved embodiment for a door handle set of the type described above, or for a door handle set equipped with such a set, or for a method for mounting such a door handle set, or for a method for mounting such a door handle set, which is characterized in particular by a reduced effort during assembly, while at the same time rapid assembly is possible.

[0008] This problem is solved according to the invention by the subject matter of the independent claims. Advantageous embodiments are the subject matter of the dependent claims.

[0009] The invention is based on the general concept of separating the locking function generated by the bayonet fitting from the preload function generated by the spring, so that the rotary adjustment required to move the bayonet fitting into its closed position can be performed without interaction with the spring. This means that when installing the door handle set, the installer does not have to exert any force against the spring's restoring force to create the open position of the bayonet fitting or to align the indentation and protrusion of the bayonet fitting. As a result, the installer can mount a large number of door handle sets with minimal effort and virtually without fatigue. It is noteworthy that the installation of the door handle set according to the invention remains quick and easy.

[0010] Specifically, the invention proposes that the cover cap is rotatably arranged on the door handle relative to the positioning plate about the pivot axis, and that the cover cap has the opposite of the indentation and protrusion of the bayonet fitting, so that the cover cap is or can be fixed axially fixed to the mounting plate with respect to the pivot axis by means of the bayonet fitting, and that the positioning plate is or can be fixed rotationally fixed to the mounting plate with respect to the pivot axis. When the door handle set is mounted, the positioning plate is rotationally fixed to the mounting plate, allowing the spring's restoring force to be transmitted via the positioning plate to the mounting plate and from there to the door. The cover cap can be rotated relative to the door handle and relative to the positioning plate, and thus also relative to the mounting plate, without the positioning plate itself having to rotate.Since the positioning plate is supported by the spring on the door handle and the rotation of the cover cap occurs relative to the door handle and relative to the positioning plate, the rotation of the cover cap does not affect the spring and can therefore take place independently of the spring force.

[0011] A bayonet fitting is configured for the axial connection of two components and is characterized by the fact that, to establish the axial connection, the two components are first axially inserted into one another in an open position of the bayonet fitting and then rotated relative to each other to create a closed position of the bayonet fitting. This creates a positive engagement by the elements of the bayonet fitting. These elements are a recess on one component and a complementary protrusion on the other component. The protrusion can be formed by at least one radially projecting projection. The recess can be formed by at least one depression corresponding to the respective projection, which has an axial section for axially inserting the two components and a circumferential section for rotating the two components.

[0012] In the present context, a "configuration" corresponds to a "design" and / or a "setup", so that the phrase "configured so that" is synonymous with the phrase "designed so that" and / or "set up so that".

[0013] According to an advantageous embodiment, the bayonet lock can be equipped with a detent that secures the bayonet lock in a closed position, wherein, in the closed position, the cover cap and thus the mounting unit formed by the door handle are axially fixed to the mounting plate. The detent ensures that, in the closed position of the bayonet lock, the cover cap is rotationally fixed to the mounting plate with respect to the pivot axis. In other words, the detent prevents the bayonet lock from being opened.

[0014] According to an advantageous embodiment, the detent can be provided with a latch formed on the mounting plate and configured to be radially spring-elastic with respect to the pivot axis, and a detent opening formed on the cover cap into which the latch engages radially with respect to the pivot axis to secure the cover cap against rotation relative to the mounting plate. Such a configuration is characterized by high reliability and stability. Furthermore, the latch and detent opening can be easily aligned so that the latch can be actuated through the detent opening to unlock or disengage the cover cap, namely by being pressed radially inwards, thus making it possible to rotate the cover cap again to open the bayonet lock.In particular, the latch and locking mechanism can be aligned in such a way that unlocking the bayonet lock is only possible with the aid of a tool, and in particular cannot be done manually.

[0015] Securing the cover cap in the closed position of the bayonet lock prevents unintentional opening of the bayonet lock. It also prevents the door handle set from being removed from the door without permission.

[0016] The mounting plate can be conveniently configured as a plastic part. In particular, the latch can be formed by an integral section of the mounting plate. This makes it especially easy to mold the latch onto the mounting plate.

[0017] According to an advantageous embodiment, the indentation of the bayonet fitting can be formed on the mounting plate, while the protrusion of the bayonet fitting is formed on the cover cap. When the mounting plate is configured as a plastic part, the indentation can be created particularly easily during the manufacturing process of the mounting plate. The cover cap can advantageously be a metal component on which the protrusion can be easily produced.

[0018] A particularly advantageous embodiment is one in which the bayonet lock is configured such that a rotational movement of the cover cap relative to the mounting plate about the pivot axis forces an axial movement of the cover cap relative to the mounting plate about the pivot axis, and in particular, axially clamps the cover cap to the mounting plate about the pivot axis. This kinematics can be generated, for example, by a slope in the circumferential section of the recess. This ensures that when the bayonet lock is closed, a predetermined relative position is established for the cover cap and thus for the entire assembly unit formed with the door handle, relative to the mounting plate. In particular, this eliminates all manufacturing tolerances.

[0019] According to an advantageous embodiment, the positioning plate can have one or more projections for rotationally fixing the positioning plate to the mounting plate. These projections engage axially in a corresponding recess on the mounting plate, relative to the pivot axis. This ensures a reliable and stable torque transmission between the positioning plate and the mounting plate by means of a positive fit, so that when the door handle is turned or pressed down, the restoring force of the spring can be supported on the door via the positioning plate and the mounting plate.

[0020] According to an advantageous embodiment, the positioning plate can have at least one radial recess on its edge, extending circumferentially between a first end stop and a second end stop. The cover cap can be equipped with at least one cam that engages radially in the recess, such that rotational adjustment about the pivot axis between the cover cap and the positioning plate is limited by the two end stops. This ensures that the cover cap cannot be rotated arbitrarily about the pivot axis with respect to the positioning plate, but only within a rotational angular range defined by the two end stops of the respective recess.This makes it easier, especially during assembly, to find the open position of the bayonet lock, in which the indentation and the protrusion can be axially engaged, so that the bayonet lock can then be moved into the closed position.

[0021] It may be advantageous to design the cover cap so that it is rotatable relative to the positioning plate between a first end position, in which the indentation and protrusion of the bayonet lock can be axially engaged, and a second end position, in which the bayonet lock assumes its closed position. It is designed so that the cam rests against the first end stop in the first end position and against the second end stop in the second end position. In this way, the suitability of the cover cap is determined by the targeted dimensioning of the respective radial recess on the positioning plate, such that in the first end position the bayonet lock is in its open position, allowing the indentation and protrusion to be axially engaged, while in the second end position the bayonet lock is in its closed position, thus ensuring the door handle is properly mounted.

[0022] According to an advantageous embodiment, the polygonal receptacle can have a receiving opening, a receiving area coaxial with the pivot axis surrounding the receiving opening, and a clamping sleeve inserted axially into the receiving opening with respect to the pivot axis, into which the polygonal pin can be inserted axially with respect to the pivot axis. Advantageously, the clamping sleeve can be configured such that when the polygonal pin is inserted into the clamping sleeve, the clamping sleeve is clamped between the polygonal pin and the receiving area, and the polygonal pin is held axially in the receiving area by clamping force. By using such a clamping sleeve, positive-locking fasteners, such as a screw, especially a setscrew, can be dispensed with. This simplifies the assembly process.

[0023] The clamping sleeve has an inner cross-section that is complementary to the outer cross-section of the polygonal pin. The polygonal pin is usually a square pin, which in particular has a substantially square cross-section.

[0024] According to an advantageous embodiment, the clamping sleeve can have at least one longitudinal projection on its radial inner surface, which faces a radial outer surface of the polygonal pin. This longitudinal projection extends axially and projects radially inwards. When the polygonal pin is inserted into the clamping sleeve, this longitudinal projection comes into contact with the polygonal pin and can generate or enhance the clamping effect. The clamping effect between the polygonal pin and the receiving area is generated by deformation of the clamping sleeve. This deformation occurs when the polygonal pin is inserted into the clamping sleeve. In particular, it can be provided that the clamping sleeve is elastically and / or plastically deformed to generate the clamping force. The deformation of the clamping sleeve, especially the plastic deformation, preferably takes place in the area of ​​the respective longitudinal projection. The clamping sleeve can, in particular, be a plastic component.

[0025] According to an advantageous embodiment, the door handle can have a bearing section extending coaxially to the pivot axis and featuring the polygonal receptacle, and a handle section projecting transversely from the bearing section. The handle section can be configured as a depressable lever or as a rotatable knob.

[0026] According to an advantageous embodiment, the door handle set can have a spring which, with respect to the pivot axis in the circumferential direction, is supported on the one hand by the door handle and on the other hand by the positioning plate, and which, particularly in the case of a door handle set mounted on a door, biases the door handle in the circumferential direction into the unactuated starting position. Particularly in the case of a door handle set mounted on a door, the spring allows the door handle to automatically assume the predefined starting position in the unactuated state, resulting in a high-quality appearance and improved user-friendliness.

[0027] According to an advantageous embodiment, the positioning plate can have a stop cam which, in the initial position of the door handle, rests against the first stop of the stop ring. The spring then presses the positioning plate with the stop cam against the first stop of the stop ring. This establishes a predetermined preload that must be applied by the user when the door handle set is installed in order to depress or turn the door handle.

[0028] The spring can also be conveniently supported on the stop cam of the positioning plate, thus giving the stop cam a dual function.

[0029] A particularly advantageous embodiment is one in which the stop ring has a second stop that defines an operating position limiting the pivoting action of the door handle, with the stop cam bearing against the second stop in the operating position. The second stop limits the rotation of the door handle, thus preventing over-pressing and excessive deformation of the spring.

[0030] A door handle set according to the invention, designed for operating a door lock, comprises a first door handle set and a second door handle set, each comprising a door handle, a mounting plate, and a cover cap. The first door handle set is configured as described above, while the second door handle set has a multi-sided spindle that is rotationally and axially fixed to the door handle of the second door handle set. The mounting plate of the first door handle set can be attached to, or is attached to, the mounting plate of the second door handle set through the door.

[0031] An assembly method according to the invention for mounting a door handle set of the type described above is characterized in that the mounting plate is first attached to the door coaxially with a polygonal spindle, and the door handle is then placed onto the polygonal spindle such that the spindle engages in the polygonal recess. In the initial position of the door handle, the indentation engages with the protrusion of the bayonet fitting. Furthermore, in the initial position of the door handle, the positioning plate is fixed to the mounting plate in a rotationally fixed manner. Subsequently, the cover cap is rotated about the pivot axis such that the bayonet fitting is moved into its closed position. Once the bayonet fitting is in its closed position, the door handle set is fully assembled.

[0032] If the bayonet fitting is equipped with a detent, the fitter is notified that the closed position has been reached by an audible and / or tactile click of the detent.

[0033] A method for mounting a door handle set on a door that has a first door side and a second door side facing away from the first involves, in a first step, mounting the second door handle set on the second door side such that the spindle penetrates the door and protrudes from the first door side. Following this, the first door handle set is mounted on the first door side. The mounting of the first door handle set is carried out as described above, whereby the mounting plate of the first door handle set is first attached through the door to the mounting plate of the second door handle set. Subsequently, the door handle of the first door handle set is placed onto the spindle so that the spindle engages in the spindle recess. In the initial position of the door handle, the indentation engages with the protrusion of the bayonet fitting.Furthermore, in the door handle's initial position, the positioning plate is fixed to the mounting plate in a rotationally fixed manner. Finally, the cover cap is rotated around the pivot axis so that the bayonet lock is moved into its closed position.

[0034] Further important features and advantages of the invention will become apparent from the dependent claims, the drawings and the associated description of the figures based on the drawings.

[0035] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention. Components of a higher-level unit, such as a device, apparatus, or arrangement, mentioned above and those to be mentioned below, which are designated separately, can form separate parts or components of this unit or be integral areas or sections of this unit, even if this is depicted differently in the drawings.

[0036] Preferred embodiments of the invention are shown in the drawings and are explained in more detail in the following description, wherein identical reference numerals refer to identical or similar or functionally identical components.

[0037] They show, schematically, Figure 1 is an isometric view of a door handle set with two door handle sets, Figure 2 is an expanded isometric view of the door handle set made of Figure 1 Figure 3 shows an expanded isometric view of the door handle set as shown in Figure 2 , however, from a different perspective, Figure 4 shows an expanded isometric view of the door handle set as in Figure 2 , however with more details, Figure 5 an isometric view of a door handle return set with separate mounting plate, Figure 6 a view as in Figure 5, however with a changed viewing direction for the mounting plate, Figure 7 a longitudinal section of the door handle set in the area of ​​the mounting plate, Figure 8 an isometric view of a positioning plate, Figure 9 an isometric view of a clamping sleeve, Figure 10 a partially sectioned isometric view of the door handle set, Figure 11 a partially sectioned view of the door handle set, Figure 12 an isometric view of a front side of the mounting plate, Figure 13 a view as in Figure 12 , however, from a different perspective, Figure 14 an isometric view of a rear side of the mounting plate, Figure 15 an isometric view of a cover cap, Figure 16 a sectional view of the door handle set in the area of ​​the cover cap.

[0038] According to the Figures 1 to 4 includes a door handle set 1, which is used to operate a door in Figure 11 with a broken line symbolically indicating door lock 49 of one also in Figure 11The door 48, indicated by a broken line, is configured with a first door handle set 2 and a second door handle set 3, each comprising a door handle 4, a mounting plate 5, and a cover cap 6. The second door handle set 3 is also equipped with a polystyrene spindle 7, configured here as a square spindle with a square cross-section. The polystyrene spindle 7 is rotationally and axially fixed to at least the door handle 4 of the second door handle set 3 with respect to a pivot axis 8. Both door handles 2 and 3 are pivotably arranged about the pivot axis 8.

[0039] The pivot axis 8 defines an axial direction that extends parallel to the pivot axis 8. The pivot axis 8 thus also defines a radial direction that extends perpendicular to the axial direction and, in particular, is perpendicular to the pivot axis 8. Furthermore, the pivot axis 8 defines a circumferential direction 13 that revolves around the pivot axis 8. The circumferential direction 13 is indicated in the figures by a double arrow.

[0040] In the Figure 1 In the assembled state shown, the mounting plate 5 of the first door handle set 2 is attached to the mounting plate 5 of the second door handle set 3 through the door (not shown here).

[0041] The first door handle set 2, referred to here as door handle set 2, is described in more detail below. The second or other door handle set 3 may be configured identically, similarly, or differently than door handle set 2. Door handle set 2 is configured for door handle set 1 and, as mentioned, comprises a door handle 4, a mounting plate 5, a cover cap 6, as well as a positioning plate 9, a spring 10, and a stop ring 11.

[0042] The door handle 4 has a polygonal receptacle 12, coaxial with the pivot axis 8, for receiving the polygonal spindle 7. The cover cap 6 is rotatably and axially fixedly mounted on the door handle 4 with respect to the pivot axis 8. The spring 10 serves to pre-tension the door handle 4 to an unactuated initial position in the circumferential direction 13. For this purpose, the spring 10 is supported in the circumferential direction 13 on one side by the door handle 4 and on the other side by the positioning plate 9. The stop ring 11 is rotationally fixed to the door handle 4 with respect to the pivot axis 8 and has a first stop 14 that defines the initial position. The rotationally fixed connection between the stop ring 11 and the door handle 4 is achieved, by way of example, by the stop ring 11 having two radially inward projections 15 that extend radially inwards and, in the assembled state, engage in axial slots 16 formed on the door handle 4.

[0043] The mounting plate 5 is fixed to the door in the assembled state, preventing rotation and axial movement with respect to the pivot axis 8. The door handle set 2 shown here also features a bayonet fitting 17, which has a recess 18 and a complementary protrusion 19. In the door handle set 2 presented here, the bayonet fitting 17 is located between the mounting plate 5 and the cover cap 6. Accordingly, the mounting plate 5 has one of the recess 18 and protrusion 19, while the cover cap 6 has the other. In the example shown here, the mounting plate 5 has the recess 18, while the cover cap 6 has the protrusion 19. The cover cap 6 can be fixed axially to the mounting plate 5 by means of the bayonet fitting 17. The positioning plate 9 is fixed to the mounting plate 5 in a rotationally fixed position when the door handle set 2 is installed.

[0044] How in particular the Figure 13 and 15 The bayonet fitting 17 can be equipped with a detent 20 configured to secure the bayonet fitting 17 in a closed position. In the closed position, the cover cap 6 is fixed to the mounting plate 5 in a rotationally fixed manner. The detent 20 can be configured according to the Figure 13 and 15 The mounting plate 5 has a latch 21 and the cover cap 6 has a detent opening 22. The latch 21 is designed according to Figure 13 radially spring-elastic configuration and can be inserted into the Figure 15The detent opening 22 shown engages radially, such that the cover cap 6 is thereby secured against rotation in the circumferential direction 13 relative to the mounting plate 5 by a positive fit. The mounting plate 5 can advantageously be configured as a plastic part. The latch 21 can be formed by an integral section of the mounting plate 5. The detent opening 22 is formed on a collar 29 of the cover cap 6 and is configured as a through-opening. This allows the latch 21 to be actuated from the outside to release the locking mechanism. Advantageously, the latch 21 and detent opening 22 are configured so that a tool is required for this purpose.

[0045] According to the Figure 12 and 13The bayonet fitting 17 or the recess 18 can be configured such that a rotational movement of the cover cap 6 about the pivot axis 8 forces an axial adjustment of the cover cap 6 relative to the mounting plate 5, thereby adjusting the cover cap 6 relative to the mounting plate 5 and, in particular, axially clamping it. The recess 18 has, according to the Figure 12 and 13 Two diametrically opposed recesses 44 are provided, each having an axial section 45 and a circumferential section 46. For coupling the rotary adjustment with an axial adjustment, the circumferential section 46 has a ramp 47 to create a gradient. The corresponding bulge 19 is shown in the diagram. Figure 15 formed by two webs 52 which project radially inwards at the collar 29 of the cover cap 6 and are diametrically opposite each other.

[0046] When the door handle set 2 is installed, the positioning plate 9 is fixed to the mounting plate 5 in a rotationally fixed manner. For this purpose, the positioning plate 9 can be adjusted according to the Figures 5 to 8 The positioning plate 9 has one or more axially projecting protrusions 23. Complementarily, the mounting plate 5 can have a corresponding number of axial recesses 24. In the example shown, exactly four protrusions 23 are formed on the positioning plate 9. Complementarily, the mounting plate 5 has exactly four recesses 24 at complementary positions. To fix the positioning plate 9 to the mounting plate 5 in a rotationally fixed manner, the protrusions 23 engage axially in the recesses 24, thereby creating a positive-locking connection in the circumferential direction 13.

[0047] According to Figure 8The positioning plate 9 has at least one radial recess 25 at its edge. In the example shown, the positioning plate 9 has two such recesses 25, which are diametrically opposed to each other. Each recess 25 extends in the circumferential direction 13 between a first end stop 26 and a second end stop 27. Complementary to each recess 25, the cover cap 6 has Figure 15 at least one cam 28. In the example shown here, the cover cap 6 has two such cams 28, each of which interacts with one of the recesses 25 and which are diametrically opposed to each other for this purpose. Figure 15 Only the lower cam 28 is visible. The diametrically opposite upper cam is in Figure 15The surrounding collar 29 of the cover cap 6 conceals the cam. The respective cam 28 engages radially in the respective recess 25 such that rotation between the cover cap 6 and the positioning plate 9 is limited by the two end stops 26, 27. Advantageously, the cover cap 6 can be rotated relative to the positioning plate 9 between a first end position, in which the respective cam 28 rests against the respective first end stop 26, and a second end position, in which the respective cam 28 rests against the respective second end stop 27. In the first end position, the cover cap 6 is aligned via the positioning plate 9, which is fixed to the mounting plate 5, such that the indentation 18 and the protrusion 19 can be axially engaged. This corresponds to the open position of the bayonet fitting 17.In the second end position, the cover cap 6 is rotated relative to the positioning plate 9 and thus relative to the mounting plate 5 so far that the bayonet lock 17 assumes its closed position.

[0048] According to the Figures 1 to 7 and in particular according to the Figures 9 to 11The polygonal receptacle 12 comprises a receiving opening 30, a receiving area 31 that surrounds the receiving opening 30 coaxially with the pivot axis 8, and a clamping sleeve 32, which is axially inserted into the receiving opening 30 and into which the polygonal pin 7 can be axially inserted. This clamping sleeve 32 is configured such that when the polygonal pin 7 is inserted into the clamping sleeve 32, the clamping sleeve 32 is clamped between the polygonal pin 7 and the receiving area 31, thereby generating a clamping force that axially secures the polygonal pin 7 in the receiving area 31. The receiving area 31 is a component of the door handle 4 and can, for example, have the axial slots 16 mentioned above, via which the stop ring 11 is rotationally fixed to the door handle 4.

[0049] According to Figure 9The clamping sleeve 32 can have several longitudinal projections 33 on its radial inner surface, which project radially inwards and extend axially. When the polygonal pin 7 is axially inserted or pressed into the clamping sleeve 32, the clamping sleeve 32 is deformed, at least elastically, particularly in the area of ​​the longitudinal projections 33. In particular, plastic deformation of the clamping sleeve 32 can also occur. This allows a high clamping force to be achieved, which axially secures the polygonal pin 7 in the clamping sleeve 32 by friction and force, while simultaneously securing the clamping sleeve 32 in the receiving area 31 and thus on the door handle 4 also by friction and force.

[0050] The door handle 4 has a bearing section 34 extending coaxially to the pivot axis 8, on which the polygonal receptacle 12 is formed. In particular, this bearing section 34 has the receiving area 31 and / or the axial slots 16. Furthermore, the door handle 4 has a handle section 35 projecting transversely from the bearing section 34, which here is configured in a U-shape. In another embodiment, the handle section 35 can also be designed as a knob, a rotary knob, or a rotary handle.

[0051] According to Figure 8The positioning plate 9 can have a stop cam 36 which, in its initial position, rests against the first stop 14 of the stop ring 11. In the example shown here, the stop ring 11 also has a second stop 37, which limits the pivoting action of the door handle 4 to a predetermined operating position, in which the door handle 4 is pivoted to its maximum extent. In other words, the second stop 37 defines this operating position. It is advantageous for the stop cam 36 of the positioning plate 9 to rest against the second stop 37 in the operating position. Since, on the one hand, the stop ring 11 is rotationally fixed to the door handle 4, and on the other hand, the positioning plate 9 is rotationally fixed to the mounting plate 5, the unactuated door handle 4 is automatically returned to its initial position by the restoring force of the spring 10.Torques applied by the user to the door handle 4 are supported via the mounting plate 5 on the door.

[0052] The spring 10 is configured here as a coil spring. For rotationally fixed support of the spring 10 on the door handle 4, the spring 10 can have an inwardly angled inner spring end 42 on its radial side, which, in the assembled state, engages in one of the axial slots 16 of the door handle 4. Radially on its outer side, the spring 10 can have an outwardly angled outer spring end 43, which is also supported on the stop cam 36 of the positioning plate 9.

[0053] For mounting the door handle set 1 on a door 48, which according to Figure 11If the door has a first door side 50 and a second door side 51 facing away from the first door side 50, the second door handle set 3 is first attached to the second door side 51 on the door 48, such that the multi-sided spindle 7 passes through the door 48 and, if applicable, through the door lock 49, and projects axially from the first door side 50. The first door handle set 2 can then be attached to the first door side 50 on the door 48. The first door handle set 2 is mounted by first attaching the mounting plate 5 of the first door handle set 2 through the door 48 to the mounting plate 5 of the second door handle set 3. Screws 38, for example, can be used for this purpose, which are inserted into the Figures 1 to 4All other components of the first door handle set 2 form an assembly unit 39, in which the cover cap 6 and the positioning plate 9 are rotatably arranged on the door handle 4, and in which the stop ring 11 is fixedly arranged on the door handle 4. Furthermore, the spring 10 pre-tensions the positioning plate 9 relative to the door handle 4 into its initial position, so that the initial position exists within the assembly unit 39. The individual components are axially secured to the door handle 4 by means of a retaining ring 40, which is axially supported on the stop ring 11 via a washer 41.

[0054] When the mounting unit 39 is attached, the door handle 4 of the first door handle set 2 is axially inserted onto the polystyrene spindle 7, such that the polystyrene spindle 7 penetrates axially into the polystyrene receptacle 12. The door handle 4 thus assumes its initial position. The cover cap 6 also assumes its first end position, in which the indentation 18 and the protrusion 19 are aligned with each other so that the bayonet fitting 17 is in the open position, allowing the indentation 18 and the protrusion 19 to engage axially. Simultaneously, the positioning plate 9 is aligned relative to the mounting plate 5 with respect to its rotational position such that the projections 23 of the positioning plate 9 are axially congruent with the recesses 24 of the mounting plate 5 and can engage axially therein. This fixes the positioning plate 9 to the mounting plate 5 in a rotationally fixed manner.Subsequently, the cover cap 6 can now be rotated about the pivot axis 8, i.e., rotated in the circumferential direction 13, such that the bayonet lock 17 is moved into its closed position. Simultaneously, with a corresponding incline in the recess 18, this creates a final axial adjustment between the cover cap 6 and thus the entire mounting unit 39 relative to the mounting plate 5.

[0055] Provided that the clamping sleeve 32 is used as suggested here, no additional measures are required to fix the first door handle set 2 to the multi-sided pin 7, so that after the cover cap 6 has been completely turned to the closed position, the assembly process is completed.

[0056] If the bayonet fitting 17 is equipped with the detent 20, the fitter can rotate the cover cap 6 in the circumferential direction 13 until the detent 20 audibly and / or tangibly engages, thus signaling that the bayonet fitting 17 has reached the closed position.
