The door has two through holes for the tensioning screws and for the bushings receiving them. Between the two bores there is a cylindrical cut on the outside of the door to accommodate a cylindrical extension.

Rotary stops between the driver and the housing ensure a defined rotary end position of the handle. This reset part is combined with the bearing part to form a structural unit by providing openings in the hat brim of the housing for the two bushings provided on the bearing part. The bearing part lies in front of the hat opening of the reset part, while the hat brim is supported on the outside of the door.

The reset devices for handling a fitting, which are already known in the prior art, still leave room for improvement.

It is therefore an object of the present invention to provide a resetting device for handling a fitting, which can be adjusted particularly easily between two different stop positions, in particular between left-hand and right-hand operation.

According to the invention, it is therefore proposed in a first aspect to provide a resetting device for handling a fitting. The reset device has a shield coupling element, a spring element and a handle coupling element. The shield coupling element has a stop element which has a first stop surface and a second stop surface. The spring end has a first spring end and a second spring end. The handle coupling element is rotatable relative to the shield coupling element in a circumferential direction about an axis of rotation at least between a first handle stop position and a second handle stop position. The handle coupling member and the spring member are coupled between the first handle stop position and the second handle stop position in the circumferential direction. The spring device or the spring element is in the by a rotary movement of the handle coupling element Rotatable in the circumferential direction between a first spring stop position and a second spring stop position. In the first spring stop position, the first spring end rests on the first stop surface. In the second spring stop position, the second spring end rests in the second stop surface.

Furthermore, it is proposed in a second aspect to provide a fitting with a handle and the restoring device according to the first aspect, the handle coupling element of the restoring device being coupled in a rotationally fixed manner to the handle in the circumferential direction.

• Bereitstellen der Rückstellvorrichtung, wobei die Rückstellvorrichtung ein Schildkupplungselement, ein Federelement und ein Handhabenkupplungselement aufweist, wobei das Schildkupplungselement ein Anschlagelement aufweist, wobei das Anschlagelement eine erste Anschlagfläche und eine zweite Anschlagfläche aufweist, wobei das Federelement ein erstes Federende und ein zweites Federende aufweist, wobei das Handhabenkupplungselement relativ zu dem Schildkupplungselement in einer Umfangsrichtung um eine Drehachse zumindest zwischen einer ersten Handhabenanschlagposition und einer zweiten Handhabenanschlagposition drehbar ist, wobei das Handhabenkupplungselement und das Federelement zwischen der ersten Handhabenanschlagposition und der zweiten Handhabenanschlagposition in der Umfangsrichtung gekoppelt sind;
• Anordnen des Handhabenkupplungselements in der Handhabenanschlagposition, wobei das Federelement bzw. die Federeinrichtung in einer ersten Federanschlagposition angeordnet ist, in der das erste Federende an der ersten Anschlagfläche anliegt; und
• Drehen des Handhabenkupplungselements in der Umfangsrichtung von der ersten Handhabenanschlagposition in eine zweite Handhabenanschlagposition, so dass das Federelement in einer zweiten Federanschlagposition angeordnet ist, in der das zweite Federende an der zweiten Anschlagfläche anliegt.

Furthermore, it is proposed in a third aspect of the invention to provide a method for transferring a return device of a handle of a fitting between a first handle stop position and a second handle stop position. The process has the following steps:

• Provision of the reset device, the reset device having a shield coupling element, a spring element and a handle coupling element, the shield coupling element having a stop element, the stop element having a first stop surface and a second stop surface, the spring element having a first spring end and a second spring end, the The handle coupling element is rotatable relative to the shield coupling element in a circumferential direction about an axis of rotation at least between a first handle stop position and a second handle stop position, the handle coupling element and the spring element being coupled in the circumferential direction between the first handle stop position and the second handle stop position;
• Arranging the handle coupling element in the handle stop position, the spring element or the spring device being arranged in a first spring stop position, in which the first spring end abuts the first stop surface; and
• Rotating the handle coupling element in the circumferential direction from the first handle stop position into a second handle stop position, so that the spring element is arranged in a second spring stop position in which the second spring end bears against the second stop surface.

The orientation of the reset device in space is defined with respect to the axial direction, the radial direction and the circumferential direction. These three directions thus define a three-dimensional coordinate system. This coordinate system can generally also be specified in Cartesian coordinates, the axial direction, the radial direction and the circumferential direction resulting from corresponding transformations from the Cartesian coordinates into cylindrical coordinates. The axis of the axial component corresponds to the axis of rotation of the components of the reset device.

The handle coupling element is designed to be rotationally coupled with a handle of the fitting. In an assembled state of the fitting, the handle coupling element is coupled to the handle in a rotationally fixed manner. The shield coupling element is designed to be rotationally fixedly coupled to a shield of the fitting. In an assembled state of the fitting, the shield coupling element is coupled to the shield in a rotationally fixed manner.

The rotational movement of the handle coupling element between the first handle stop position and the second handle stop position in the circumferential direction takes place in the assembled state. The handle coupling element can be rotated from the first handle stop position to the second handle stop position or from the second handle stop position to the first handle stop position. As a result, the spring device or the spring element is rotated from the first spring stop position into the second spring stop position or from the second spring stop position into the first spring stop position.

In general, spring support in door handles, even when the springs in the lock are tired or weak, should cause the handle to return to its normal position defers. The basic position is usually the horizontal of the handle up to a position that deviates 2 ° upwards.

Depending on the opening direction of the door, lever handles that are pointing to the left or to the right are required, i.e. are designed for left-hand or right-hand operation. The reset device according to the invention enables the handle of a door to be easily moved into the corresponding position without the use of a tool. From there, a spring return force acts in the usual direction of actuation, i.e. downwards. It is therefore not necessary that individual parts have to be converted, removed, repositioned or even changed. In other words, it is a closed assembly that allows the handle orientation to be determined conveniently directly at the door when assembled, without the risk of small parts being lost or the need to re-tension the spring.

In some known locks, it is common that the handle must first be raised against the usual direction of actuation, downwards, that is to say it must be moved upwards, before locking can take place via the locking cylinder. Locking elements can be moved out, for example, via this lever upward movement. When using the resetting device according to the invention, no spring is tensioned during this push-up movement, since the resetting device is moved between the first handle stop position and the second handle stop position, between which the spring element does not bear against a stop of the shield coupling element. As a result, the comfort remains with these locks to move the locking element as far as possible using a large handle, without additional force having to be applied to tension the spring. It is not necessary to support the restoring force from the upward movement of the pusher back into one of the handle stop positions, since gravity supports it in this direction.

In other words, the reset device according to the invention enables the handle stop position to be easily changed over without the need for additional conversion, changeover or repositioning of components of the reset device. Instead, the reset device according to the invention can, in an assembled state, in particular an assembled state, be rotated particularly easily between two handle stop positions by simply rotating the handle coupling element.

The task at the beginning is thus completely solved.

In one configuration of the resetting device it can be provided that the spring device or the spring element furthermore has a winding, the first spring end and the second spring end extending inwards from the winding in a radial direction with respect to the axis of rotation, in particular with the winding the spring device or the spring element is arranged radially outside of the stop element and the handle coupling element.

Here, in particular, the winding is arranged symmetrically to the axis of rotation. The first and second stop surfaces are also arranged radially on the inside of the winding. The first and second spring ends extend inwards towards the respective stop surface.

In a further embodiment of the reset device it can be provided that the handle coupling element has a first contact surface and a second contact surface, the first spring end being coupled to the first contact surface and the second spring end being coupled to the second contact surface in the circumferential direction between the first handle stop position and the second handle stop position are, in particular wherein the first spring end abuts the first contact surface and the second spring end abuts the second contact surface when the handle coupling element is arranged between the first handle stop position and the second handle stop position.

This arrangement rotates the spring device or the spring element between the first spring stop position and the second spring stop position when the handle coupling member is rotated between the first handle stop position and the second handle stop position.

In a further embodiment of the reset device, it can be provided that the first contact surface and the second contact surface face each other in the circumferential direction.

As a result, the two spring ends are arranged between the first and second contact surfaces in the circumferential direction.

In a further embodiment of the reset device it can be provided that the handle coupling element is designed as a sleeve element, the sleeve element having a first recess and a second recess on the side facing the shield coupling element, each of which extends in the circumferential direction, the first spring end in the first recess and the second spring end is arranged in the second recess.

This enables each spring end to be movable in the respective recess in the circumferential direction. If the handle coupling element is rotated further in the stop direction from the first or the second handle stop position, then the spring device or the spring element is tensioned, since one spring end in the respective spring stop position is fixed to the respective stop surface and the other spring end is rotated further, since that other spring end rests on the respective contact surface of the handle coupling element.

In a further embodiment of the reset device, it can be provided that the first recess forms the first contact surface and a first counter surface opposite the first contact surface perpendicular to the circumferential direction, the second recess perpendicular to the circumferential direction forming the second contact surface and a second counter surface opposite the second contact surface forms, in particular wherein a depth of the first recess in the axial direction is less than a depth of the second recess.

As described above, in one of the spring stop positions, the respective spring end lies against the respective stop surface of the stop element of the shield coupling element. If the handle coupling element is rotated further and the spring element is thereby tensioned, the handle coupling element continues to rotate while the respective spring end rests on the respective stop surface. The respective contact surface moves away from the respective spring end and the corresponding counter surface moves towards the respective spring end. The counter surface thus forms a further stop in the circumferential direction for the respective spring end. In particular, the handle coupling element can only be rotated in the circumferential direction up to the rotational position in which the respective spring end comes into contact with the respective counter surface.

In a further embodiment of the resetting device it can be provided that the first spring stop position is different from the second spring stop position.

In particular, the two stop surfaces of the shield coupling element are spaced apart from one another in the circumferential direction. Furthermore, the orientation of the spring element in the first spring stop position is different from the orientation of the spring element in the second stop position. The spring element can be transferred from the first spring stop position into the second spring stop position by rotating in the circumferential direction about the axis of rotation. The first and the second spring stop positions are designed such that the required rotation in the circumferential direction is less than a complete rotation about the axis of rotation. In other words, the angle difference with respect to the axis of rotation between the first spring stop position and the second spring stop position is less than 360 °. The angle difference is preferably between 166 ° and 180 °, more preferably between 176 ° and 180 °, in particular 176 °.

In a further embodiment of the resetting device it can be provided that the first stop surface and the second stop surface are arranged in the circumferential direction on opposite sides of the stop element.

As a result, in the first spring stop position, the first end lies on the first stop surface, which is arranged on one side of the stop element. In the second spring stop position, the second spring end rests on the second stop surface on an opposite side of the stop element. The rotary movement of the handle coupling element is accordingly carried out in such a way that one spring end is turned away from the corresponding stop surface and the other spring end is turned towards the corresponding opposite stop surface.

In a further embodiment of the reset device, it can be provided that the shield coupling element and the handle coupling element are arranged adjacent to one another in an axial direction with respect to the axis of rotation.

The shield coupling element is preferably arranged on the inside with respect to the fitting, that is to say axially on the inside or facing the shield, and the handle coupling element is arranged on the outside with respect to the fitting, that is to say axially on the outside or facing the handle.

In a further embodiment of the reset device, it can be provided that the shield coupling element furthermore has a disc element, the stop element extending in an axial direction from the disc element in the direction of the handle coupling element.

In this embodiment, the disk element is arranged outside the handle coupling element in the axial direction. The stop element extends in the axial direction towards the handle coupling element, in particular into the handle coupling element. This enables both the stop element and the handle coupling element to form stop or contact surfaces for the two spring ends.

In a further embodiment of the reset device it can be provided that the reset device further has a housing in which the shield coupling element, the spring element and the handle coupling element are rotatably supported in the circumferential direction.

The housing accordingly forms a guide for the shield coupling element, the spring element and the handle coupling element of the reset device in the circumferential direction. However, the shield coupling element does not rotate relative to the housing.

In a further embodiment of the fitting, it can be provided that the fitting furthermore has a shield, the shield coupling element of the restoring device being coupled in a rotationally fixed manner to the shield, the shield and the handle being rotatably coupled in relation to one another in the circumferential direction via the restoring device, in particular , wherein the reset device is arranged in the shield or on an outside of the shield.

This arrangement of the fitting enables the handle to be rotatable in the circumferential direction relative to the shield between the first handle stop position and the second handle stop position.

In a further embodiment of the fitting, it can be provided that in the first handle stop position and in the second handle stop position the handle is essentially upward at an angle of 0 ° to 7 °, preferably 0 ° to 2 °, in particular 2 ° is rotated, in particular wherein the handle is oriented in the first handle stop position for left-hand operation of the fitting and in the second handle stop position for right-hand operation of the fitting.

In this arrangement of the fitting, the handle can be pivoted between left-hand and right-hand operation.

In a further embodiment of the fitting, provision can be made for a rotation from the first handle stop position to the second handle stop position or from the second handle stop position to the first handle stop position the handle is turned upside down.

The handle is turned upwards from the corresponding handle stop position and turned back down after reaching a vertical position. In other words, the handle is turned counterclockwise starting from right-hand operation and turned clockwise starting from left-hand operation.

In a further embodiment of the method it can be provided that in the rotating step the spring device or the spring element is rotated in the circumferential direction from the first spring stop position into the second spring stop position.

As a result, the spring device or the spring element can be transferred from a first spring stop position to a second spring stop position without having to make a structural change to the restoring device, for example by turning around, converting, or repositioning in a component of the restoring device.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the combination indicated in each case, but also in other combinations or on their own without departing from the scope of the present invention.

The Figures 1 and 2nd show the structure of a fitting 10 in an isometric view and a side view. Such a fitting can be used for example as a door fitting or window fitting. The fitting has a shield 12, a handle 14 and a reset device 16.

The shield 12, the handle 14 and the reset device 16 are arranged relative to one another with respect to a coordinate system 100. The coordinate system 100 is shown in Cartesian coordinates x, y, z. Furthermore, the coordinate system is also represented in cylindrical coordinates, which can be derived from the Cartesian coordinates. The cylinder coordinates define three directions, namely an axial direction 102, which corresponds to the direction of the z-axis, a radial direction 104, which lies in the x, y plane and which extends away from the z-axis, and a circumferential direction 106, which also lies in the x, y plane and rotates around the z axis. The axial direction 102 and the radial direction 104 are oriented perpendicular to one another. The circumferential direction 106 is oriented perpendicular to the radial direction 104 and runs around the axial direction 102.

The handle 14 is rotatably mounted relative to the shield about an axis of rotation 108. The axis of rotation 108 lies in the axial direction 102. The radial direction 104 extends perpendicular to the axis of rotation 108 away from the axis of rotation 108. The circumferential direction 106 runs around the axis of rotation 108. The axis of rotation is in the Figure 4 described in more detail.

The reset device 16 is fastened to the shield 12 with fastening means 18. The fastening means can be designed, for example, as screws. In the present exemplary embodiment, four screws 18 'to 18 "" are provided as fastening means in order to fasten the reset device 16 to the door plate 12.

The door plate 12 also has an opening 20. The reset device can be inserted into the opening. On the other hand, the square handle can be pushed through the opening in order to couple it to the handle 14.

The opening 20 also has two recesses 22 'and 22 "which are located on a radially outer edge of the opening and extend radially outward. A corresponding shield coupling element 26 of the reset device 16 is above these recesses 22', 22" complementary shaped lugs 34 ', 34 ", which can be inserted into the corresponding recesses 22', 22", can be connected in a rotationally fixed manner. The shield coupling element 26 is used in the following 3 to 5 described in more detail.

Furthermore, the handle 14 is coupled to the reset device 16. In particular, the handle 14 is rotatably connected to a handle coupling element 30 of the reset device 16. The handle coupling member 30 is shown in the following Fig. 3 , 4th and 7 described in more detail.

Fig. 3 shows the structure of the reset device 16 and the handle 14 coupled to the reset device 16 in an isometric view. Figure 4 shows the structure Fig. 3 in an exploded view (A) and a longitudinal sectional view (B).

In the embodiment of the Figures 3 and 4th the reset device 16 has a housing 25, the shield coupling element 26, a spring element 28, and the handle coupling element 30. In the housing 25, the spring element 28 and the handle coupling element 30 are rotatably supported in the circumferential direction 106 about the axis of rotation 108. The shield coupling element 26 is also carried by the housing 25. However, the shield coupling member 26 does not rotate relative to the housing 25.

The housing has bores 24 'to 24 "", in the corresponding fastening means 18' to 18 "", which in the Fig. 1 can be used to secure the reset device 16 to the shield 12.

The shield coupling element 26 has two lugs 34 ', 34 ", which extend into the complementarily shaped recesses 22', 22" of the shield 12 of the fitting 10 Fig. 1 can be used to connect the shield coupling element 26 to the shield 12 in a rotationally fixed manner.

The spring element 28 has a winding 46 which surrounds the handle coupling element 30. In other words, the winding 46 of the spring element 28 is radially outward with respect to the handle coupling element 30. The spring element is subsequently shown in FIG Figure 6 described in more detail.

Furthermore, the resetting device 16 can have a connecting element 94 that couples the handle coupling element 30 to the handle 14 in a rotationally fixed manner. For this purpose, the connecting element 94 has, on the side facing the handle coupling element 30, two recesses 95 ′, 95 ″ arranged radially on the outside and opposite in the circumferential direction 106, into which complementarily shaped lugs 62 ′, 62 ″ of the handle coupling element 30 can be inserted, around the handle coupling element 30 to be connected to the connecting element 94 in a rotationally fixed manner. Furthermore, the connecting element 94 has a receptacle for a square handle. The recesses 95 ', 95 "can be arranged on a radially outer edge of this receptacle.

On the side of the connecting element 94 facing the handle 14, which faces away from the handle coupling element 30, the connecting element 94 can be connected in a rotationally fixed manner to the handle 14. The connecting element 94 is sleeve-shaped and has on the side facing the handle 14 an outer diameter that is smaller than a corresponding inner diameter of a receptacle of the handle 14 for the connecting element 94, so that the connecting element 94 can be inserted into this receptacle, preferably without play . To connect the connecting element 94 and the handle 14, it can be provided, for example, that fastening means are used. In particular, the connecting element 94, when it is used in the assembled state of the fitting 10 in the receptacle of the handle 14, can be connected in a rotationally fixed manner to the handle 14 by fastening means. In particular, it can be provided as a fastening means that the connecting element 94 is glued to the handle 14 by means of an adhesive, screwed and / or pressed in by means of a screw.

However, the design of the connecting element 94 and the handle 14 described in the preceding two paragraphs is not mandatory. The handle 14 and the connecting element 94 can also be formed as one part or can be firmly connected to one another, for example by means of a material connection such as welding.

Furthermore, the reset device can have a bearing sleeve 92, by means of which the connecting element 94 is rotatably mounted in the housing 25. The bearing sleeve 92 is formed from two sleeve elements 93 ', 93 ", the sleeve elements 93', 93" being arranged adjacent in the axial direction 102.

The Fig. 10 shows a schematic view of a method for transferring the return device 16 of the handle 14 of the fitting 10 between a first handle stop position 74 and a second handle stop position 80.

The reset device 16 is provided in a first step 122 of the method 120. The reset device 16 can be provided in accordance with the reset device 16, which in the 1 to 9 is shown.

In a further step 124 of the method 120, the handle coupling element 30 is arranged in the first handle stop position 74. The spring device or the spring element 28 is arranged in the first spring stop position 70, in which the first spring end 48 ′ bears on the first stop surface 40 ′.

In a further step 126 of the method 120, the handle coupling element 30 is rotated in the circumferential direction 106 from the first handle stop position 74 to the second handle stop position 80, so that the spring device or the spring element 28 is arranged in the second spring stop position 72, in which the second spring end 48 "abuts the second stop surface 40".

In the step of rotating 126, the spring device or the spring element 28 is preferably rotated in the circumferential direction 106 from the first spring stop position 70 to the second spring stop position 72.

The 11 to 15 show different operating states of the reset device 16 from the 1 to 9 . Here are in the 11 to 15 Top views of the restoring device 16 are shown, each from a viewing direction which is directed from the inside to the outside with respect to an arrangement in the fitting 10, that is to say from the restoring device 16 in the direction of the handle 14. To the different operating states of the reset device 16, the disk element 31 is omitted from the shield coupling element and only the stop element 38 is shown. The Fig. 11 , 13 and 14 show various operating states that occur in the method 120 that is shown in FIG Fig. 10 is described.

To transfer the reset device 16 between the in the Figures 11 to 15 In the operating states shown, the handle coupling element 30 is rotated in a first direction of rotation 84 or in a second direction of rotation 86. The first and the second direction of rotation 84, 86 run in the circumferential direction 106 and opposite to one another. The first direction of rotation 84 runs from the first handle stop position 74 to the second handle stop position 76, that is to say in FIGS Figures 11 to 15 direction of view shown counterclockwise. The second direction of rotation 86 runs from the second handle stop position 76 to the first handle stop position 74, that is to say in FIGS Figures 11 to 15 direction of view shown clockwise.

In the Fig. 11 the handle coupling element 30 is arranged in the first handle stop position 74. The first spring end 48 'bears on the first contact surface 56'. In addition, the first spring end 48 'also abuts the first stop surface 40'. The second spring end 48 ″ bears on the second contact surface 56 ″. The spring element 28 is accordingly arranged in the first spring stop position 70.

In Fig. 12 the handle coupling element 30 is arranged in a first handle end position 76. This operating state is reached when, starting from the operating state of the first handle stop position 74 from the Fig. 11 the handle coupling element 30 is rotated in the second direction of rotation 86 and thus the second contact surface 56 "is also moved in the circumferential direction 106 towards the first stop surface 40 '. As a result, the first spring end 48' detaches from the first contact surface 56 'and the first counter surface 58 'of the handle coupling element 30 is moved towards the first spring end 48'.

In the first handle end position 76, the first spring end 48 'lies in the circumferential direction on one side on the stop surface 40' and on the other side on the counter surface 58 '. The second spring end 48 ″ bears on the second contact surface 56 ″. The spring element 28 is thus also arranged in the first spring stop position 70. The fact that the first spring end 48 ′ bears against both the stop surface 40 ′ and the counter surface 58 ′ means that the handle coupling element 30 is blocked in the second direction of rotation 86. However, it is envisaged that the counter surface 58 'will not actually be reached during operation. Instead, a limitation of the operating angle of the handle is achieved by a further element, which is present in the entire locking device and is not shown.

As a result, the spring element 28 is pretensioned in the first handle end position 76 in the first direction of rotation 84. In other words, the spring element 28 acts on the handle coupling element 30 with a restoring force in the first direction of rotation 84, that is to say in the direction of the first handle stop position 74. As a result, the handle 14 can be returned to the first handle stop position 74 by means of this restoring force.

In Fig. 13 An intermediate state is shown in which the handle coupling element 30 is arranged in an intermediate handle position 78. This state is reached when starting from the first handle stop position 74, which in Fig. 11 is shown, the handle coupling element 30 is rotated in the first direction of rotation 84 or, starting from the second handle stop position 80, which in the Fig. 14 is shown, the handle coupling element 30 is rotated in the second direction of rotation 86. The intermediate handle position 78 is accordingly between the first handle stop position 74 and the second handle stop position 80.

In the intermediate handling position 78, the first spring end 48 ′ bears on the first contact surface 56 ′ and the second spring end 48 ″ on the second contact surface 56 ″. The first spring end 48 ′ is arranged at a distance from the first stop surface 40 ′ and the second spring end 48 ″ is spaced apart from the second stop surface 40 ″ in the circumferential direction 106. In other words, none of the spring ends 48 ′, 48 ″ bears against a stop surface of the stop element 38.

In Fig. 14 Another operating state is shown in which the handle coupling element 30 is arranged in the second handle stop position 80. Here, the second spring end 48 "lies on the second stop surface 40". In addition, the second spring end 48 ″ also abuts the second contact surface 56 ″. The first spring end 48 'only bears on the first contact surface 56'. The spring element 28 is accordingly arranged in the second spring stop position 72.

In Fig. 15 A further operating state of the reset device 16 is shown, in which the handle coupling element 30 is arranged in the second handle end position 82. This condition is reached when starting from that in the Fig. 14 shown operating state, in which the handle coupling element 30 is arranged in the second handle stop position 80, the handle coupling element 30 is rotated further in the first direction of rotation 84. The second spring end 48 ″ detaches from the second contact surface 56 ″ and the second counter surface 58 ″ moves toward the second spring end 48 ″.

In the second handle end position 82, the first spring end 48 'bears on the first contact surface 56'. The second spring end 48 "lies in the circumferential direction 106 on one side against the second stop surface 40" and on the other side against the second counter surface 58 ". The spring element 28 is thus also arranged in the second spring stop position 72 the second spring end 48 "bears against both the stop surface 40" and the counter surface 58 ", the handle coupling element 30 is blocked in the first direction of rotation 84. However, it is provided that the counter surface 58 "is not actually reached during operation. Instead, a further element, which is present in the entire locking device and is not shown, is used to limit the actuation angle of the handle.

The spring element 28 is biased in the second direction of rotation 86. In other words, the spring element 28 acts on the handle coupling element with a restoring force in the second direction of rotation 86, that is to say in the direction of the second handle stop position 80. As a result, the handle 14 can be reset into the second handle stop position 80 by means of this restoring force.
