Description

[0001] The invention relates to an actuating unit for a panic door lock with features of the preamble of claim 1. The invention further relates to a panic door lock and a door or window arrangement with the features of the respective dependent claims.

[0002] An operating unit for a panic exit device of the type mentioned above is known to the applicant from practical experience and is available on the market, for example, under the name "BKS bar handle for active leaf B-74000". This operating unit has two base parts, two lever arms, and a handle connected to the lever arms. The lever arms are each pivotally mounted on one of the base parts and pre-tensioned in the unactuated position by means of torsion springs. One of the lever arms engages with a nut rotatably mounted on one of the base parts, whereby the nut is driven by rotation when the respective lever arm is pivoted. This drive of the nut takes place on the side facing away from the lever arm or the handle ("operating from the left"), so that a housing for the operating unit requires a corresponding amount of space. Depending on the door or window configuration (different movement curves), this may therefore require additional space.A collision can occur between an active leaf and a fixed leaf, where the housing of an operating unit and a free end of the opposite leaf collide (so-called "binding"). This can impair the smooth operation of a door or window assembly due to wear marks and acoustic emissions from the collision.

[0003] The invention is based on the objective of contributing to the smoothest possible operation of an actuating unit and door or window arrangements equipped with it, using simple design means.

[0004] The invention solves this problem by means of an actuating unit with the features of claim 1.

[0005] The operating unit is designed and / or intended for use with a panic exit device. The operating unit comprises at least one base, at least one lever arm, and a handle. The base can extend (along a vertical direction) from a lower end facing the handle to an upper end facing away from the handle.

[0006] The base part comprises a base section and a wall section projecting from the base section and forming an angle with the base section. A nut is rotatably mounted on the base section of the base part about an axis of rotation (first bearing point). In the case of multiple base parts, a nut can only be provided on one base part.

[0007] On the wall section of the base, the lever arm is pivotally mounted at one end around a pivot axis (second bearing point). The lever arm can pivot between an unactuated position ("rest position"; lever arm pivoted away from the base) and an actuated position ("panic position"; lever arm pivoted towards the base). At the other end, at least one lever arm is connected to the handle.

[0008] A gearbox is arranged between the nut and the wall section, via which the lever arm is coupled to the nut, so that when the lever arm is pivoted around the pivot axis (via the gearbox) the nut is rotated around the axis of rotation or driven in a rotating manner.

[0009] The gearbox comprises a first gearbox element and a second gearbox element. The first gearbox element is rotationally fixed to the lever arm. The second gearbox element is pivotally mounted on the wall section about a further pivot axis. The second gearbox element engages with the first gearbox element on one side and with the nut on the other.

[0010] Integrating a gearbox into the drive train between the lever arm and the socket allows for greater flexibility in positioning the lever arm axis. Unlike the aforementioned rod handle, where the lever arm axis is directly adjacent to or positioned above the socket's axis of rotation, the lever arm axis can now be moved away from the socket's axis of rotation and "upwards" along the base. This allows for a longer lever arm while maintaining the same handle tube position. Positioning the gearbox between the socket and the wall section also allows for a narrower base section, resulting in a more compact design. Furthermore, the base plate and any housing covering the base, such as a cover, can be made more compact on the side of the socket facing away from the wall section (since the socket is actuated on the side facing the wall section).This saves space and prevents the actuator unit and door profile from being compressed.

[0011] The base section of the main part may have a mounting side or mounting surface on the side facing away from the pivot axis or lever arm, with which the main part can be mounted on a wing of a door or window.

[0012] As already explained above, the base part has a base section and a wall section projecting from the base section and forming an angle with the base section. The base section and the wall section can form an angle of 85° to 95°, preferably 90°, with each other. In other words, the central longitudinal plane of the base section and the central longitudinal plane of the wall section can preferably be oriented orthogonally to each other.

[0013] A bearing point (second bearing point) can be formed on the wall section, at which the lever arm is pivotally mounted about the pivot axis mentioned above. The bearing point can have a bore whose central axis coincides with the pivot axis (congruence). The lever arm can be pivotally attached to the bearing point by means of a screw, e.g., a shoulder bolt. Independently of this, the spindle, which is rotatably mounted on the base section, can be coupled, e.g., by means of a square drive, to a mortise lock (spindle) of a panic exit device, in particular in a rotationally fixed manner.

[0014] The first gear element and its associated lever arm are pivotally mounted about the same (first) pivot axis (second bearing point). The second gear element can be rotatably mounted by means of a pin (second pivot axis) spaced from the (first) pivot axis and formed on the wall section. The pivot axis and the second pivot axis can be oriented parallel to each other.

[0015] The lever arm can be open on one side, particularly on the side facing the base. In this case, the hollow space of the lever arm faces the base and is open towards it. The lever arm can also be closed on another side, particularly on the side facing away from the base.

[0016] In this context, the term "actuating unit" refers in particular to the device that can be mounted or is mounted on a door or window sash, which serves to trigger the panic door lock and is designed as a type A rod actuation (handle bar according to EN 1125).

[0017] Specifically, the actuating unit can comprise two base parts, two lever arms, and a handle connected to the lever arms. Each lever arm is pivotally mounted on one of the base parts.

[0018] Specifically, the further pivot axis around which the second gear element is pivotally mounted and the pivot axis around which the lever arm is pivotally mounted can be oriented parallel to each other.

[0019] In a preferred embodiment, the first gear element and the lever arm can be materially bonded together, for example, by a welded construction. This allows the gear element and the lever arm to be designed independently of each other and stably connected by the material bond. Alternatively or additionally, the first gear element and the lever arm can be formed in one piece, for example, as a cast construction or a construction milled from a solid block. This simplifies manufacturing, as production steps (the material bonding step and any necessary pre- and post-processing) can be eliminated. Regardless of this, the first gear element and the lever arm can be arranged directly adjacent to each other or include an intermediate section between them. The intermediate section can, for example, be...It must be equipped to accommodate a storage site, in particular the second storage site.

[0020] Advantageously, the first gear element can have a first toothed section and the second gear element can have a second toothed section, wherein the first gear element and the second gear element mesh with each other via the first and second toothed sections. This ensures a reliable coupling of the gear elements, whereby the toothed sections are always engaged at at least one point (contact point of the toothed sections) during a pivoting movement.

[0021] Specifically, the first gear section and / or the second gear section can each have involute teeth or be designed as involute teeth. This allows the coupling of the first gear element with the second gear element to be optimized in such a way that improved transfer of force or torque from the lever arm to the second gear element is possible.

[0022] Advantageously, the second gear element, particularly adjacent to the second gear section, can have an arm section (nut actuation section) that can be engaged, or is engaged, with an actuation arm of the nut (formed on the nut and preferably projecting laterally from the nut) to drive the nut. This allows for a structurally simple and stable coupling of the second gear element with the nut. A rotational movement of the second gear element about the further pivot axis is thereby converted into a rotational movement of the nut about its axis of rotation.

[0023] As already indicated above, the arm section (nut actuation section) and the actuating arm of the nut can be arranged in particular on the side of the nut facing the wall section and / or the lever arm (actuation takes place on the left base part "from the right").

[0024] Advantageously, the first gear section can have two teeth and a tooth gap between them, wherein the second gear section has at least one tooth that projects into or is located in the tooth gap of the first gear section. This contributes to a reliable coupling between the first and second gear elements.

[0025] Advantageously, the secondary pivot axis of the second gear element can be oriented parallel to the pivot axis of the lever arm (and optionally also parallel to the central longitudinal plane of the base section), with the secondary pivot axis of the second gear element having a greater distance from the central longitudinal plane than the pivot axis of the lever arm. This increases the design flexibility of the second gear element. Different gears can be installed on the actuating unit, thus allowing for adjustment of the so-called dimension or distance W (the projection of the handle when the lever arm is unactuated, relative to the wing leaf or the mounting side or surface of the base). This adaptability expands the range of applications for the actuating unit.

[0026] Specifically, the further pivot axis around which the second gear element is pivotably mounted can be arranged along a vertical direction between the axis of rotation of the nut and the pivot axis around which the lever arm is pivotably mounted.

[0027] Advantageously, a stop surface can be formed on the first gear element or on the lever arm, which interacts with a counter-stop surface arranged on the wall section adjacent to the pivot axis to limit the pivoting movement of the lever arm about the pivot axis away from the base section of the main part. This creates a defined end stop at which the gear elements of the transmission are not subjected to any load. The lever arm can pivot between an unactuated position (starting or rest position) and a fully actuated position (panic position), with the stop surface and counter-stop surface limiting the pivoting movement of the lever arm away from the base section (to the rest position).

[0028] Advantageously, the first gear element can have a stop arm that interacts with a counter-stop formed on the base part to limit the pivoting movement of the lever arm about the pivot axis towards the base section of the base part. This also creates a defined end stop at which the gear elements of the transmission are not loaded. The lever arm can pivot between an unactuated position and a fully actuated position, with the stop arm and counter-stop limiting the pivoting movement of the lever arm towards the base section. The counter-stop can preferably be adjustable, for example, by means of an adjusting element, in particular an adjusting screw. The base part can have a further base section that is arranged (at the upper end) between the base section and the wall section and connects the base section and the wall section.The further basic section can accommodate or house the adjusting element in an adjustable manner, e.g. by means of a threaded bore for an adjusting screw.

[0029] In a preferred embodiment, an interchangeable component can be provided which differs from the second gear element, wherein the interchangeable component can be installed in place of the second gear element on the gearbox or is already installed. In other words, the second gear element can be replaced by the interchangeable component. In the installed state, the interchangeable component (analogous to the second gear element) is coupled to the first gear element on one side and to the nut on the other, so that when the lever arm pivots about the pivot axis, the nut can be driven to rotate about the axis of rotation. By replacing the second gear element with the interchangeable component, the distance between the handle or the end of the lever arm facing the handle and the mounting side of the base part can be adjusted.The distance to the surface of a door or window sash, on which the operating unit is mounted, can be varied (setting dimension W according to DIN 1125; once dimension W < 150 mm and once dimension W < 100 mm). Specifically, installing the replacement part can result in a smaller distance (smaller dimension W or dimension W').

[0030] The aforementioned problem is also solved by a set comprising the features of the dependent claim. Regarding the advantages, reference is made to the relevant explanations concerning the actuating unit and the replacement part.

[0031] The set includes an actuating unit with one or more of the aspects described above, as well as a replacement part which differs from the second gear element and can be installed in place of the second gear element on the gearbox or is already installed (as explained above).

[0032] The set may optionally include a replacement nut, which differs from the nut described above and can be installed in place of the nut on the base part, or is already installed. The replacement nut (analogous to the nut) is mounted on the base section of the main part, allowing it to rotate around its axis of rotation when installed. The replacement nut may differ from the nut, in particular, in that the actuating arm of the replacement nut projects in a different direction, especially in the opposite direction, than the actuating arm of the nut (e.g., a mirror-symmetrical arrangement of the actuating arm). Thus, by replacing the second gear element with the replacement part and by replacing the nut with the replacement nut, it is possible to switch between the fixed and active leaf, as well as between the left and right door or window leaf.

[0033] The measures explained above and / or discussed below can be used to further develop the set.

[0034] The aforementioned problem is also solved by a panic door lock with the features of the dependent claim. Regarding the advantages achievable thereby, reference is made to the relevant explanations concerning the actuating unit.

[0035] The panic exit device is designed and / or intended for locking and / or unlocking a pivoting door or window sash relative to a door or window frame. The panic exit device has an operating unit with one or more of the aspects described above.

[0036] In a preferred embodiment, a (wing-side) locking device with at least one locking element (latch and / or bolt) can be provided, wherein the locking device is coupled to the actuating unit in such a way that the locking element can be actuated by means of the actuating unit. In particular, the locking element can be displaceable between an extended position (relative to the locking device) and a retracted position (relative to the locking device). The locking device can be designed as a mortise lock.

[0037] Specifically, the actuator's nut can be non-rotatably coupled to the nut of the locking mechanism or mortise lock by means of a square drive. The coupling is thus configured so that when the handle is pivoted, not only the actuator's nut but also (through the square drive coupling) the nut of the locking mechanism or mortise lock is actuated. This allows the locking element of the locking mechanism to be moved into the retracted position.

[0038] It may be expedient to provide a (frame-side) strike plate with which the locking element of the locking device can be engaged (in the extended position).

[0039] The measures explained above and / or discussed below can be used to further develop the panic door lock.

[0040] The task mentioned at the beginning is also solved by a door or window arrangement with a frame (door or window frame), a sash pivotably mounted on the frame (door or window sash) and a panic door lock with one or more of the aspects described above.

[0041] The operating unit and the locking mechanism are arranged and / or attached to the sash of the door or window assembly. The operating unit can be mounted on a flat side of the sash, and the locking mechanism can be mounted on or in the sash, for example, as a mortise lock. The operating unit and the locking mechanism can be coupled by means of a square spindle, as described above. The strike plate can be mounted on the frame so that the locking element of the locking mechanism can engage with the strike plate (the locking element can penetrate the opening of the strike plate).

[0042] The measures explained above and / or discussed below can be used to further design the door or window arrangement.

[0043] The invention is explained in more detail below with reference to the figures, where identical or functionally identical elements are provided with identical reference numerals, possibly only once. The figures show: Fig. 1 shows an embodiment of an actuating unit in a perspective view; Fig. 2 shows the actuating unit made of Figure 1 in a perspective exploded view; Fig. 3a, a base part and a lever arm of the actuating unit made of Figure 1 in a perspective partial view ( Figure 3a ) and a partially cropped side view ( Figure 3b ); Fig. 4a - your base part, a lever arm and a second gear element ( Figure 4b ) of the actuating unit Figure 1 in a perspective partial view ( Figure 4a ) and a side view ( Figure 4c) each in the unactuated position and a side view in the actuated position ( Figure 4d ); Fig. 5a - your base part, a lever arm and a replacement part ( Figure 5b ) of the actuating unit Figure 1 in a perspective partial view ( Figure 5a ) and a side view ( Figure 5c ) each in the unactuated position and a side view in the actuated position ( Figure 5d ); and Fig. 6a, the basic part of the actuating unit made of Figure 1 in isolation in a perspective view ( Figure 6a ) as well as in a front view and a side view ( Figure 6b ).

[0044] Figure 1Figure 1 shows a door arrangement 200 with a frame 202 and a leaf 204 pivotally mounted on the frame 202 (leaf and frame are shown only schematically). The leaf 204 can pivot relative to the frame 202 between an open position and a closed position and can be mounted on the frame 202, for example, by means of hinges (not shown).

[0045] Figure 1 Figure 100 also shows a panic door lock 100 for locking and unlocking the sash 204 on the frame 202. The panic door lock 100 has an actuating unit 10 which is mounted on the sash 204 and is described further below.

[0046] Furthermore, the panic door lock 100 has a locking device 102 with a locking element 104, wherein the locking device 102 is designed as a mortise lock. The locking element 104 can be a latch, a bolt, or a latch bolt.

[0047] The locking device 102 is coupled to the actuating unit 10 in such a way that the locking element 104 can be actuated by means of the actuating unit 10, and thus can be moved between a position retracted relative to the locking device 102 and a position extended relative to the locking device 102.

[0048] A strike plate 106 with an opening 108 is arranged on the frame 202, with which the locking element 104 can be engaged in the closed position of the sash 204 and in the extended position of the locking element 104 (locking element 104 can penetrate into the opening 108).

[0049] As already indicated, it shows Figure 1An actuating unit 10 for a panic exit door lock. The actuating unit 10 has two base parts 12, each covered by a cover 13. The actuating unit 10 also has two lever arms 14 and a handle 16. The handle 16 can be attached to the lever arms 15 by means of coupling pieces 21 and screws 25 (see figure). Figure 2 ).

[0050] The basic parts 12 each have a bearing point 17 at which the lever arms 14 are pivotably mounted at one end about a pivot axis 18 (see Figure 1 and 2 In the example, a shoulder bolt 19 is inserted through corresponding openings in the bearing point 17 and the lever arm 14, so that the lever arm 14 is pivotably coupled to the associated base part 12. Thus, the lever arms 14 can each be moved between an unactuated position ("rest position"; see e.g. Figure 4c and 5c) and an activated position pivoted towards the base part 12 ("panic position"; cf. e.g. Figure 4d and 5d ) can be pivoted. The lever arms 14 are each connected at the other end (away from the base part 12) to the handle 16 (see figure). Figure 1 ).

[0051] The structure and function are described below using one of the basic parts 12 and one of the lever arms 14 (in this case the left elements), whereby the other basic part 12 and the other lever arm 14 can be constructed analogously, e.g. mirror-symmetrically.

[0052] The basic part 12 has a base section 20 and a wall section 22 projecting from the base section 20 and forming an angle with the base section 20 (see Figure 2 ). The mid-longitudinal plane 20' of the base section 20 (cf. Figure 3b and 6b ) and the central longitudinal plane 22' of the wall section 22 (cf. Fig.6b) are oriented orthogonally to each other in the example. The base section 20 has a mounting side 23 on the side facing away from the wall section 22 or the pivot axis 18, with which the base part 12 can be mounted on the sash 204 (see figure). Figure 3b The bearing point 17, on which the lever arm 14 is pivotally mounted, is in this case formed on the wall section 22 (see e.g. Figure 6a ). The base part 12 has a further base part section 27, which is arranged (at the upper end) between the base section 20 and the wall section 22 and connects the base section 20 and the wall section 22.

[0053] The lever arm 14 has a cavity 24 (see Figure 3b ). A guide element 26 and a spring element 28, guided by the guide element 26, are arranged in the cavity 24. The guide element 26 and the spring element 28 are designed to hold the lever arm 14 and the handle 16 in the unactuated position (see Figure 24). Figure 3b) to hold. In this example, the spring element 28 is designed as a compression spring and the guide element 26 as a double-flat.

[0054] The guide element 26 has a (convex) contour at its end facing the base part 12, which rests against a (concave) counter contour formed on the base part 12 (cf. Figure 4 The contour and the counter contour define a joint whose joint axis 34 is arranged eccentrically to the pivot axis 18 of the lever arm 14. The counter contour is fixed to the wall section 22 of the base part 12. Thus, the counter contour is also fixed to the pivot axis 18 of the lever arm 14.

[0055] The spring element 28 holds the lever arm 14 in the unactuated position via the guide element 26. When the handle 16 is actuated in the direction of the actuated position (towards the base part 12), force must be overcome by the spring element 28.

[0056] The lever arm 14 is open on a side 36 facing the base part 12 (cavity 24 open towards the base part 12; cf. Figure 3b The lever arm 14 is closed on a side 38 facing away from the base part 12.

[0057] The spring element 28 is designed as a helical spring 29 (compression spring), and the guide element 26 extends through the interior of the helical spring 29 (central cavity). The guide element 26 has a shoulder 40 at which the guide element 26 transitions from a first cross-section 26', which extends through the interior of the helical spring 29, to a second cross-section 26'', which projects beyond the coils of the helical spring 29, so that the shoulder 40 forms a first stop for the helical spring 29.

[0058] In the section of the guide element 26 with the first cross-section 26', the side edges of the guide element 26 facing the open side 36 and the closed side 38 of the lever arm 14 can serve as guide surfaces for the helical spring 29. The guide element 26 extends in an arc shape at least in the area where the spring element 28 (helical spring 29) and the guide element 26 overlap (overlap area) (cf. Figure 3b ).

[0059] In the cavity 24, a projection 46 protrudes, which has a passage 48 through which the guide element 26 extends, the coil spring 29 bearing against a side 49 of the projection 46 (facing the coil spring 29), so that the projection 46 forms a second stop for the coil spring 29 (cf. Figure 3bIn this example, the projection 46 extends from the closed side 38 of the lever arm 14 to the open side 36 of the lever arm 14 and does not protrude from the lever arm 14. The passage 48 is designed as a slot that is open towards the open side 36 of the lever arm 14. The projection 46 is angled towards the helical spring 29, at least on the side 49 facing the helical spring 29, and at least at the free end of the projection 46, so that the helical spring 29 is secured in the cavity 24.

[0060] As explained above, the base section 20 of the base part 12 has a central longitudinal plane 20' and the wall section 22 of the base part 12 has a central longitudinal plane 22' (see Figure 3b and 6bThe pivot axis 18 of the lever arm 14 and the joint axis 34 are oriented parallel to each other and to the central longitudinal plane 20' of the base section 20, with the joint axis 34 having a smaller distance to the central longitudinal plane 20' of the base section 20 than the pivot axis 18 of the lever arm 14 (cf. Figure 4 ).

[0061] A nut 54 is rotatably mounted on the base section 20 of the base part 12 about a rotation axis 56, wherein the rotation axis 56 is oriented orthogonally to the central longitudinal plane 20' of the base section 20 (cf. Figure 3a and 3b The joint axis 34 is located at a smaller distance from the pivot axis 56 of the nut 54 than the pivot axis 18 of the lever arm 14 (cf. Figure 3b (Nut 54 is omitted there for clarity). The nut 54 can be screwed to the base section 20 of the main part by means of screws 57 and a retaining part 58 (see figure). Figure 2 A threaded pin 59 can be screwed into the nut 54, e.g. for adjustment purposes.

[0062] The base part 12 extends from a lower end 51 facing the rod handle 16 to an upper end 53 facing away from the rod handle 16. The pivot axis 56 of the nut 54 is arranged in a lower half 55' of the base part 12 (in the half 55' located at the lower end 51 of the base part 12; cf. Figure 6b The pivot axis 18 of the lever arm 14 is located in the upper half 55'' of the base part 12 (in the half 55'' located at the upper end 53 of the base part 12). In the example, the pivot axis 18 of the lever arm 14 is even located in the upper third of the base part 12 (not shown separately for clarity).

[0063] On the base part 12, a gear unit 60 is arranged between the nut 54 and the wall section 22, via which the lever arm 14 is coupled to the nut 54 (see figure). Figure 3a , 4a or 5a). Thus, when the lever arm 14 is pivoted about the pivot axis 18, the nut 54 can be driven to rotate about its axis of rotation 56 via the gearbox 60.

[0064] The transmission 60 has a first transmission element 62 which is rotationally fixed to the lever arm 14 (see Figure 2 and 3a The gearbox 60 also has a second gearbox element 64, which is pivotably mounted about a further pivot axis 66 on the wall section 22 of the base part 12 and engages on one side with the first gearbox element 62 and on the other side with the nut 54 via a toothing or a projection.

[0065] The further pivot axis 66 of the second gear element 64 is oriented parallel to the pivot axis 18 of the lever arm 14 (cf. Fig.3a and 6a), wherein the further pivot axis 66 of the second gear element 64 has a greater distance from the central longitudinal plane 20' of the base section than the pivot axis 18 of the lever arm 14 (cf. Figure 6b ). The further pivot axis 66 is defined by a pin 67 on the wall section 22 of the base part 12 (see Figure 3a and 6a ), on which the second gear element 64 is rotatably mounted and secured by means of a retaining ring 68. The further pivot axis 66, about which the second gear element 64 is pivotably mounted, is arranged along a vertical direction extending from the lower end 51 to the upper end 53 of the base part 12 between the axis of rotation 56 of the nut 54 and the pivot axis 18, about which the lever arm 14 is pivotally mounted.

[0066] In this example, the first gear element 62 and the lever arm 14 are materially bonded together, as explained above. The first gear element 62 and the lever arm 14 enclose an intermediate section 70 between them (see figure). Figure 3a ). Intermediate section 70 is designed to accommodate the (second) storage site 17.

[0067] The first gear element 62 has a first toothed section 72 and the second gear element 64 has a second toothed section 74 (cf. Figure 4c The first gear element 62 and the second gear element 64 are meshed with each other via the first gear section 72 and the second gear section 74. In this example, the gear sections 72 and 74 each have involute teeth or are designed as involute teeth.

[0068] The second gear element 64 has an arm section 76 (nut actuation section 76) adjacent to the second toothed section 74, which can be engaged with an actuation arm 54' of the nut 54 formed on the nut 54 and projecting laterally from the nut 54 for the rotating drive of the nut 54 (cf. Figure 4a and b Thus, a rotary movement of the second gear element 64 about the further pivot axis 66 can be converted into a rotary movement of the nut 54 about its axis of rotation 56. In the assembled state, the arm section 76 and the actuating arm 54' of the nut 54 are arranged on the side of the nut 54 facing the wall section 22.

[0069] In the example, the first gear section 72 has two teeth 75, 77 and a gap 78 between them, while the second gear section 74 has at least one tooth 79 that projects into the gap 78 of the first gear section 72 (cf. Figure 4b and 4c ).

[0070] A stop surface 80 is formed on the first gear element 62 or on the lever arm 14, in particular on the intermediate section 70, which interacts with a counter-stop surface 81 arranged on the wall section 22 adjacent to the pivot axis 18 (see Figure 4c ). This allows the pivoting movement of the lever arm 14 about the pivot axis 18 away from the base section 20 of the base part 12 to be limited.

[0071] The first gear element 62 has a stop arm 82 which interacts with a counter-stop 83 formed on the base part 12 to limit the pivoting movement of the lever arm 14 about the pivot axis 18 towards the base section 20 of the base part 12. The counter-stop 83 can be adjustable and have an adjusting screw 84 (see Figure 1). Figure 2 ), which can be screwed into or is screwed into a threaded bore 85 of the base section 27 (see Figure 6a ).

[0072] Optionally, a replacement part 65 can be provided (see below). Figure 5b ), which differs from the second gear element 64 and is installed in the gear unit 60 in place of the second gear element 64 (cf. Figure 5a, 5c and 5d The replacement part 65 has, in this example, a toothed section 74' with a tooth 79'. Adjacent to the toothed section 74', the replacement part 65 has an arm section 76' (nut actuating section 76'). In this case, the arm section 76' of the replacement part 65 is larger than the arm section 76 of the second gear element 54.

[0073] In the installed state, the replacement piece 65 (analogous to the second gear element 64) is coupled to the first gear element 62 on one side and to the nut 54 on the other, so that when the lever arm 14 is pivoted about the pivot axis 18, the nut 54 can be driven rotating about its axis of rotation 56.

[0074] By replacing the second gear element 64 with the replacement piece 65, the distance W between the handle 16 or the end of the lever arm 14 facing the handle 16 and the mounting side 23 of the base part 12 or to the surface of a door or window sash on which the actuating unit 10 is mounted can be varied (adjusting the dimension W according to DIN 1125).

[0075] In the example, with the second gear element 64 installed, the dimension W according to DIN 1125 is once W < 150 mm (cf. Figure 4c With the replacement piece 65 installed, the dimension W' according to DIN 1125 is once W' < 100 mm (cf. Figure 5c In this way, the distance between the handle 16 or the end of the lever arm 14 facing the handle 16 and the mounting side 23 or the surface of a wing 204 can be varied in the unactuated state. In the example, installing the replacement part 65 results in a smaller distance (smaller dimension W', i.e., W' < W).
