Description

The invention relates to an operating handle for a door according to the preamble of claim 1.

An actuating handle usually includes at least one stop element which is arranged on a door leaf and is designed for the pivotable mounting of a handle such as a door handle. For such operating handles, there is often a requirement that operation of the handle can be blocked by a user of the operating handle if required, for example to lock a room. For this purpose, a large number of possible constructions are known in the prior art, with which either a movement of the handle is blocked or the movement of the handle is decoupled from a locking mechanism provided in the door.

For example, describes the DE 10 2007 030 655 A1 of the applicant such an operating handle for a door, in which a stop element is arranged on two sides of a door leaf. The stop element serves as a bearing for a handle which is connected to a locking mechanism in the door leaf by means of a square pin. In order to block the actuation of the handle and consequently the unlocking of the door if necessary, a blocking device is formed between the stop elements, which blocks movement of the handle when a blocking element is actuated. The actuating member for actuating the locking device is designed as a pivotable element which protrudes from the end face of a stop element.

GB 886 906 A shows an actuating handle with a locking device which acts directly on a polygonal pin. For this purpose, a rotatably mounted disk is provided with a cutout that has a circular section and a narrower, arcuate section. By turning the disk using an actuating element, the polygonal pin can be brought into alignment with one of the two sections for blocking or releasing the polygonal pin.

GB 03713A AD 1915 discloses an actuating handle with a locking device in which a lever can be brought into engagement with a locking disc.

GB 141 475 A , U.S.A. 4,142,748 , U.S. 2010/199727 A1 , U.S. 4,861,084A and EP 2 752 537 A2 describe other operating manipulations.

The structure of an actuating handle with a locking device for actuating the handle, as described in the aforementioned prior art, has the disadvantage that the actuating element of the locking device protrudes by a distance from the end face of the stop element, which means a comparatively large overall height and consequently an often unattractive perceived optics. Reducing the overall height by shortening the actuating element has the disadvantage that the actuating element is harder to grip, which makes it difficult to actuate the locking device.

In contrast, the present invention is based on the object of creating an actuating handle with a locking mechanism, which is characterized by a low overall height and at the same time is easy to actuate.

Main features of the invention are set out in the characterizing part of claim 1.

Configurations are the subject of claims 2 to 12.

In an actuating handle for a door, a handle for actuating a locking device arranged in the door, the actuating handle having two stop elements which can be arranged on opposite sides of a door, the handle for

Actuation of the locking device rotatable about a first axis of rotation in a first stop element is mounted, wherein the actuating handle also has a locking device, wherein the locking device has a release position in which rotation of the handle about the first axis of rotation is released, and has a locking position in which rotation of the handle about the first axis of rotation is blocked by the locking device is, wherein the actuating handle also has an actuating mechanism for the blocking device, and wherein the actuating mechanism has a sliding element which can be displaced along a circle segment centered around the first axis of rotation, wherein a displacement of the sliding element along the circle segment causes the blocking device to be actuated, is provided according to the invention, that the actuating mechanism for the blocking device is arranged on the first stop element and the blocking device is arranged between the first stop element and a second stop element, that the actuating mechanism has a rotary slide and at least one pinion, the rotary slide being mounted on the first stop element so that it can rotate about the first axis of rotation and carries or has the sliding element, wherein the pinion is mounted on the stop element so that it can rotate about a second axis of rotation, and wherein the rotary slide is operatively connected to the pinion in such a way that rotation of the rotary slide about the first axis of rotation causes the blocking device to be actuated from the release position to causes the blocking position and/or vice versa, and that the sliding element protrudes through an end face of the stop element facing the handle in the direction of the first axis of rotation.

An "actuation of the locking device" is to be understood as meaning a process in which the locking device is switched from the release position to the locking position and vice versa. The above-described use of a sliding element, which can be displaced along a circular segment centered around the axis of rotation of the handle, has the advantage that the sliding element can be made very flat, which means that the overall height of the stop element and in particular the actuating mechanism of the locking device can be kept low. At the same time, the use of such a sliding element has the advantage that it is very easy to actuate and is usually even possible with a single finger, in particular in the manner of modern operation of mobile radio devices or tablet computers by swiping movements. In contrast, the rotatable actuating member described at the outset as prior art must always be gripped with at least two fingers in order to ensure reliable actuation.

Furthermore, the inventive design of the sliding element in the actuating handle also makes it possible to simultaneously actuate the handle with one hand and to actuate the sliding element and thus the actuating mechanism with a finger of the same hand. Consequently, the handling of the structure of the actuating mechanism according to the invention is simplified compared to the prior art.

A compact design of the actuating handle according to the invention is then achieved because the sliding element protrudes through an end face of the stop element facing the handle in the direction of the first axis of rotation. An end face is to be understood as meaning that face which is arranged on the side of the stop element which faces away from the door leaf and usually faces a user of the actuating handle. In this way, the stop element of an actuating handle according to the invention can be made very flat, since the entire structure of the actuating mechanism can be sunk behind the stop element in the door leaf, with only the sliding element protruding slightly from the surface of the stop element.

According to a further embodiment, actuation of the sliding element of the actuating mechanism is simplified in that a surface of the sliding element protruding from the stop element is roughened. In this way, it is sufficient if a user of the actuating handle merely places their finger on the sliding element and that Sliding element along the circle segment with slight pressure. The roughened surface of the sliding element prevents the finger from slipping off the sliding element.

The actuation of the sliding element can also be simplified, in particular according to a further embodiment, in that the stop element has a recess in its end face, through which the sliding element projects through the end face and in which the sliding element is guided. In this case, the recess preferably limits the deflection of the sliding element along the circle segment. Consequently, the recess, through which the sliding element protrudes through the end face of the stop element, serves at the same time as a guide link for the sliding element. Furthermore, the actuating mechanism can preferably be designed such that the release position of the locking device is set on the side of a first stop of the sliding element against the recess, while the locking position of the locking device is set on the side of a second stop of the sliding element against the recess. This further simplifies the actuation of the sliding element, since a user of the sliding element only has to move the sliding element from one end of the recess to the other end of the recess for safe actuation of the sliding element and there is no ambiguity as to the position of the sliding element in the release position or the locking position of the locking device is reached.

According to a further embodiment, the locking device has at least one first locking element connected to the handle in a rotationally fixed manner and a rotatably mounted second locking element, with rotation of the second locking element bringing the second locking element into engagement with the first locking element in such a way that rotation of the handle about the first Axis of rotation is prevented by the second blocking element. With this structure, a blocking device can be implemented with simple means, which only requires a rotation of the second blocking element for actuation, ie for switching from a release position to a blocking position or vice versa.

In order to achieve a non-rotatable connection of the first blocking element with the handle of the actuating handle, the first blocking element can, for example, be slipped non-rotatably onto a polygonal pin connected to the handle, which is provided for coupling the handle to a locking mechanism formed in a door leaf. The first blocking element can have a recess, for example, into which the second blocking element engages as soon as it has been moved into the blocking position.

According to the invention, the actuating handle has two stop elements which are arranged on opposite sides of a door, the actuating mechanism for the locking device being arranged on the first stop element and the locking device being arranged between the first stop element and a second stop element. Consequently, the overall structure of the locking device can be distributed on both sides of a door, which allows for a comparatively flat structure of the locking device and consequently the actuating handle. In particular, it can be provided that the locking device is arranged on the second stop element.

The actuating mechanism has a rotary slide and at least one pinion. The rotary slide is mounted on the stop element so that it can rotate about the first axis of rotation and carries or has the slide element. The pinion is rotatably mounted on the stop element about a second axis of rotation. The rotary slide is operatively connected to the pinion in such a way that rotation of the rotary slide about the first axis of rotation causes the blocking device to be actuated from the release position to the blocking position and/or vice versa. Consequently, essentially only two elements are necessary for the construction of the actuating mechanism of the locking device, which can be arranged in a space-saving manner below a stop element. This further contributes to a low overall height of the actuating handle.

The rotary slide is preferably connected to the pinion in such a way that a rotation of the rotary slide about the first axis of rotation causes the pinion to rotate about the second axis of rotation. The rotary slide is preferably a flat element, for example a metal sheet, which rests flat on the back of the stop element, resulting in a low overall height of the actuating mechanism.

According to a preferred embodiment, it is further provided that the maximum extent of the rotary slide in the radial direction of the first axis of rotation is smaller than the minimum extent of the first stop element. Consequently, the rotary slide never protrudes beyond the first stop element in the radial direction, regardless of its rotary position. Consequently, the first stop element can be arranged completely flush with the surface of a door leaf, since no elements of the actuating device protrude beyond the first stop element in the radial direction.

According to a further embodiment, the connection of the rotary slide with the pinion is preferably realized in that the rotary slide has a toothed segment on the circumference, which meshes with the pinion. For example, as already mentioned, the rotary slide can be a flat sheet metal, in which teeth are provided in a peripheral area, which is preferably in the form of a circular segment, the shape of which is adapted to the teeth of the pinion .

According to a preferred embodiment, the toothed segment is arranged diagonally opposite the sliding element relative to the first axis of rotation on the rotary slide. In this way, a large lever can be realized between the sliding element and the toothed segment of the sliding element, which facilitates actuation of the sliding element and consequently actuation of the locking device. The circular segment of the sliding element, in which the toothed segment is formed, is preferably also centered around the first axis of rotation, so that a secure engagement of the teeth of the toothed segment with the teeth of the pinion can be ensured.

Furthermore, the actuation of the sliding element can be simplified according to a further embodiment in that the size of the pinion and the toothed segment are coordinated in such a way that a rotation of the rotary slide by 15° to 25°, preferably 20° around the first axis of rotation, causes a rotation of the pinion caused by 90 ° around the second axis of rotation. In this way, a rotation of the pinion and thus a rotation of the second blocking element can be achieved even with a small displacement path of the sliding element, which is sufficient to switch the blocking element between the release position and the blocking position. This further facilitates the handling of the sliding element, since only little effort is required to actuate the sliding element.

According to a further embodiment, the rotation of the pinion is preferably transmitted to the second blocking element in that the pinion and the blocking device are firmly connected to one another via a rotating shaft. The blocking element of the blocking device preferably sits on the shaft. According to a further embodiment, it is also provided that the pinion is arranged on a first bush and the second blocking element is arranged on a second bush, the shaft engaging in the first and second bush and being mounted in a floating manner in the first and second bush. The floating bearing of the shaft in the sockets has the advantage that the distance between the pinion and the second blocking element can be variably selected and a secure coupling of the pinion to the second blocking element is nevertheless achieved. In particular in an embodiment in which the second blocking element is arranged on a first stop element and the pinion is arranged on a second stop element, the actuating handle can be adapted to different thicknesses of a door on which the actuating handle is to be mounted. The pinion or the second blocking element can be placed on the respective sockets or fastened to them, or be designed in one piece with the corresponding sockets. In particular, a one-piece design of the pinion/second blocking element with the corresponding socket has the advantage that a high degree of stability of the actuating mechanism is generally achieved.

The shaft is preferably a polygonal pin, in particular a square pin.

In order to enable the locking device to be unlocked without actuating the sliding element, according to a further embodiment it is provided that the second bushing protrudes through the second stop element along the second axis of rotation and has a receptacle for a tool. A tool holder is to be understood, for example, as a holder for a screwdriver with a slot, Phillips head or hexagon. Thus, by using an appropriate tool, the second locking element can be rotated so that the locking device can be unlocked. The tool holder is preferably arranged in a stop element in which the sliding element is not arranged at the same time. For example, a door locked from the inside can be opened from another side of the door, for example in the event that a person has inadvertently locked themselves in.

In order to further simplify the actuation of the slide element for a user of the actuation handle, it is provided according to a further embodiment that the first stop element has a guide ring on the back, on which the rotary slide is rotatably mounted. The guide ring with the rotary slide preferably forms a latching device which, in at least two rotational positions of the rotary slide, offers increased resistance to its rotation. In this way, when the sliding element is actuated, a user receives sensory feedback when the sliding element has moved the blocking device into the release position or into the blocking position.

According to a further embodiment, the locking device is designed in that the actuating mechanism has a locking ring which is arranged on the guide ring in a rotationally fixed manner, with the rotary slide being arranged on the locking ring in a rotatable manner. The detent ring has at least one detent that engages in corresponding opposing recesses of the rotary slide at the at least two rotational positions of the rotary slide. For example, the locking ring can simply be placed on the guide ring, with the locking ring engaging in corresponding recesses in the guide ring, or vice versa. Provision can certainly also be made for the latching lug to be arranged in the rotary slide and for the opposing recesses to be formed in the latching ring.

Furthermore, according to a further embodiment it can be provided that the actuating mechanism has a mounting element which is fastened to the first stop element and fixes the rotary slide to the guide ring in the axial direction of the first axis of rotation. As a result, there is no need for the rotary slide to be fixed separately on the guide ring. Furthermore, by using a mounting element, the entire structure made up of rotary slide, locking ring and guide ring can be fixed in its position in such a way that no further fastening means are required. This further simplifies the overall structure of the actuating mechanism. The rotary slide is preferably arranged as a flat element, for example as a sheet metal, between the mounting element and the first stop element.

According to a further embodiment, the mounting element is preferably fixed to the first stop element by means of at least two fastening sockets, the fastening sockets each having at least one flange. The mounting element is then held in a non-positive manner by the mounted mounting bushings between the flanges and the first stop element. According to a further embodiment, it is provided that the fastening sockets are designed to engage in mating elements of the second stop element, with a floating bearing being formed as a result of the engagement. Consequently, the fastening sockets according to the embodiment described above fulfill a double function. On the one hand, the fastening sockets serve to fix the mounting element to the first stop element and consequently to fasten the entire actuating mechanism to the first stop element. On the other hand, the fastening bushings are used at the same time for a floating mounting of the first stop element on the second stop element, so that the spacing of stop elements arranged on different sides of a door leaf can be adjusted to the thickness of the door leaf.

In the following, features that are similar or identical to one another are marked with the same reference symbols.

1 shows a perspective view of an actuating handle 100 with two handles 102, two stop elements 104, 104 'and a hinted recognizable locking device 106. The illustrated actuating handle 100 can, for example, on a door leaf to be ordered. For this purpose, the stop elements 104, 104' are first attached to both sides of a door leaf, with the locking device 106 being arranged between the stop elements 104, 104'. The handles 102 are then attached to the stop elements 104, 104'. For this purpose, for example, a polygonal pin is passed through corresponding recesses in the stop elements 104, 104' and a mortise lock (not shown) arranged in the door leaf. The handles 102 are then fastened to the polygonal pin in a rotationally fixed manner. The mortise lock can then be actuated by actuating the handles 102, so that a bolt of the mortise lock is pulled out of a corresponding door latch and the door can be opened. in the in 1 In the example shown, the stop elements 104, 104' are disc-shaped stop elements in which the handles 102 are mounted in a centered manner.

For such actuating mechanisms of actuating handles, a mechanism is often provided which, if necessary, blocks actuation of the handle 102 so that it is no longer possible to open the door on which the handle 102 is arranged. This is achieved with the actuating handle 100 according to the invention in that the locking device 106 prevents the polygonal pin on which the handles 102 are attached from rotating about its longitudinal axis. Switching between this position, hereinafter referred to as the "locked position", and a position in which the handles 102 can be actuated, hereinafter referred to as the "release position", takes place in the actuating handle 100 according to the invention by actuating the sliding element 108 by a user. The sliding element 108 is an element that is preferably roughened on its surface and protrudes from an end face 156 of a first stop element 104 . The sliding element 108 is preferably dimensioned in such a way that it protrudes only a few millimeters beyond the end face 156, for example by 1 to 5 mm.

The sliding element 108 is mounted in the first stop element 104 in such a way that it can be displaced along a circular segment which is centered around the axis of rotation of the handle 102 or a square pin connected to the handle. For this purpose, the first stop element 104 also has a recess 110 in which the sliding element 108 is guided. A deflection of the sliding element 108 within the recess 110 can then be used to switch between the locking position and the release position of the locking device 106 . How from the 1 can also be seen, the recess 110 allows a displacement of the sliding element 108 along the circle segment in one Angular range of about 20°. In the illustrated embodiment, the recess 110 acts at the same time as a stop for the sliding element 108 and thus limits a possible displacement of the sliding element 108 along the circle segment. The end positions of the sliding element 108 in the recess preferably correspond to the released or blocked position.

In the 2 A perspective view of the internal structure of the operating handle 100 is shown. The in 1 illustrated handle 102 not shown for reasons of clarity. Like in the 2 is clearly visible, the locking device 106 and an actuating mechanism 112 for the locking device 106 are formed between the stop elements 104 and 104'. The actuating mechanism 112 is essentially arranged on the first stop element 104 shown on the right-hand side, while the locking device 106 is formed in a locking tablet 114 on the opposite side on the second stop element 104 ′ shown on the left. The locking device 106 formed in the locking tablet 114 is a mechanism which can be switched between a locking position and a release position by an appropriate actuation, as was previously described. The precise functioning of the locking device 106 will not be discussed at this point. As an example, reference is instead made to the applicant's further application mentioned at the outset, in which the functioning of such a locking tablet 114 is already described.

In the 2 It is also easy to see that the second stop element 104' is connected to the first stop element 104 via corresponding connecting means. The connecting means are on the one hand fastening sockets 116 which are arranged laterally next to a recess 118 in which a handle 102 can be mounted in the first stop element 104 . Counterpart elements, which are arranged on the opposite second stop element 104′, engage in these fastening sockets 116 . The opposing elements are mounted in a floating manner in the fastening bushings 116, so that the distance between the first stop element 104 and the second stop element 104 can be flexibly adjusted. Furthermore, a further connection between the stop elements 104, 104' is formed below the recess 118, which will be discussed in more detail below.

In the 3 is the same image detail as in 2 shown, in which case the closing tablet 114 is arranged on the first stop element 104 like the actuating mechanism 112 . The question of which stop element 104, 104' the locking tablet 114 is to be arranged on depends in most cases on the structure of the mortise lock and the corresponding recesses in the door leaf. Theoretically, the locking tablet 114 can be arranged at any desired position between the two stop elements 104 and 104' by means of a corresponding design of the actuating mechanism 112. In this way, the actuating handle 100 described can be flexibly adapted to the prevailing conditions during assembly.

In the Figures 2 and 3 It can also be seen that in the second stop element 104`, which is arranged on the left-hand side, there is a receptacle 120 for a tool, in this case a slotted screwdriver. This is located below the recess 118 for a handle 102. By inserting a tool into the receptacle 120 and rotating the receptacle 120, the locking tablet 114 can be transferred from a locked position to a release position or vice versa, without the actuating mechanism 112 being actuated with the aid of the sliding element 108 must become. A door can also be unlocked when the sliding element 108 is not accessible to a user. This can be helpful, for example, if a person has inadvertently locked himself in by actuating the sliding element 108 and is then no longer able to unlock the door. The precise mode of operation and the interaction of the locking tablet 114 with the receptacle 120 and the actuating mechanism 112 will now be discussed below.

The 4 shows an exploded view of the actuating mechanism 112 with a stop element 104 on which the actuating mechanism 112 can be arranged. The actuating mechanism 112 consists essentially of a flat rotary slide 122, a locking ring 124, a pinion 126 and a guide ring 128, which is arranged on the rear side 158 of the stop element 104 around the recess 118. Furthermore, in the exploded view of 4 a mounting element 130, two fastening bushings 116 and a shaft 132 designed as a square pin.

The stop element 104 has the recess 110 in its upper region, which is provided for guiding the sliding element 108 . The recess 110 is designed as a circular segment, which around the center of the recess 118 and therefore the subsequent axis of rotation of the handle 102 used is centered. Furthermore, two pins 144 are formed laterally next to the recess 118 of the stop element 104, the function of which will be explained below. The pins 144 can be threaded pins, for example.

The rotary slide 122 is designed as an essentially flat plate, in the middle of which an approximately circular recess 134 is designed, which is designed to be larger in diameter than the recess 118 of the stop element 104 . When the actuating mechanism 112 is in the assembled state, the rear side of the rotary slide rests on the rear side 158 of the stop element 104 . The sliding element 108 is provided above the recess 134 on the rear side of the rotary slide 122 and is preferably formed in one piece with the rotary slide 122 . The sliding element 108 is in particular in the figure 5 good to see in the exploded view of the 4 is shown from the opposite direction. A toothed segment 136 is also formed at the diagonally opposite end of the rotary slide 122 and is arranged on a circular segment which is centered around the center point of the recess 134 . The toothed segment 136 is designed to engage in a corresponding toothing of the pinion 126 . As a result, a rotation of the sliding element 122 about the center point of the recess 134 is transmitted to the pinion 126 , which then rotates about a second axis of rotation, which corresponds to the longitudinal axis of the pinion 126 .

The recess 134 of the rotary slide 122 has two recesses in the form of notches 138 on its upper circumference. These are intended to form a locking device with the locking ring 124 which, for defined positions of the rotary slide 122 relative to the locking ring 124, offers increased resistance to a rotation of the rotary slide 122. For this purpose, a locking lug 140 is provided on the locking ring 124 which can engage in the notches 138 . At the same time, the locking ring 124 serves as a pivot bearing for the rotary slide 122. For this purpose, the locking ring 124 can be fastened on the guide ring 128 in a rotationally fixed manner. For this purpose, the guide ring 128 has fastening lugs on its circumference, which engage in corresponding recesses in the locking ring 124 when the latter is placed on the guide ring 128 .

Essentially, for assembling the actuating mechanism 112 , the locking ring 124 is first placed on the guide ring 128 and then the rotary slide 122 is placed on the locking ring 124 . The centers of the respective recesses fall Elements together and are all on a common first axis of rotation, which at the same time corresponds to the axis of rotation about which a handle 102 mounted in the stop element 104 can be rotated.

The mounting element 130 is also provided for fixing the rotary slide 122 on the locking ring 124 . This is essentially a flat metal sheet with two curved wings 160 arranged on the side, which has a total of four recesses. A first central recess 142 is located centrally between the wings 160 such that its center coincides with the first axis of rotation after assembly. Furthermore, notches are provided on the sides of the first recess 142, into which corresponding mating elements of the guide ring 124 can engage, so that the guide ring 124 can no longer be rotated relative to the mounting element 130 as soon as the mounting element 130 has been brought into engagement with the guide ring 124.

A further recess 146 is provided below the recess 142 and serves to accommodate and support the pinion 126 . Furthermore, further recesses 162 are provided laterally next to the recess 142 in the wings 160 which, as will be explained below, are used to fix the mounting element 130 to the stop element 104 .

In the 6 the result of a first partial step of assembling the actuating mechanism 112 is shown. The locking ring 124 was placed on the guide ring 128 first. The rotary slide 122 was then placed on the locking ring 140 and the pinion 126 was arranged below the rotary slide 122 in such a way that the toothed segment 136 is in engagement with the toothing of the pinion 126, ie meshes with it. in the in 7 In the illustrated state of assembly, the mounting element 130 has also been placed on the locking ring 124, so that rotation of the locking ring 124 is blocked by the corresponding recesses in the recess 142 of the mounting element 130. Furthermore, the mounting bushings 116 were placed on the pins 144, which protrude through the mounting element 130 through the lateral recesses 162, whereby the mounting element 130 is fixed to the stop element 104.

In this state, the rotary slide 122 can no longer be displaced along the first axis of rotation, but can only be rotated about this first axis of rotation. When the rotary slide 122 rotates about the first axis of rotation, due to the toothed segment 136, the rotation of the rotary slide 122 is transmitted to the pinion 126, which is thereby rotated rotates a second axis of rotation. The pinion is guided through the recess 146 of the mounting element 130 . The rotation of the pinion 126 about the second axis of rotation is transmitted to the locking mechanism of the locking tablet 114 by means of the square pin 132 . This will be discussed below with reference to 9 explained. The distance between the first axis of rotation and the second axis of rotation can be 21.5 mm, for example.

In the 8 is again a plan view of the subject of 7 shown, wherein a section through the mounting bushings 116 is also shown. It is easy to see that the mounting bushings are plugged onto the pins 144 and are thus fixed to the stop element. Furthermore, a peripheral flange 148 is formed on the fastening sockets 116 near the stop element 104 . The mounting element 130 is clamped between this flange 148 and the stop element 104 when the fastening bushings 116 are fastened to the pins 144 . The mounting element 130 rests only with the curved wings 160 on the rear side 158 of the stop element 104 . Due to the S-shaped curved shape of the wings, a space is created between the stop element 104 and the mounting element 130 in which the rotary slide 122 is arranged.

In this case, the fastening bushings 116, as has already been explained above, are simultaneously designed for supporting a mating element of an opposite stop element 104. Consequently, the fastening bushings 116 fulfill a dual function, since on the one hand they serve to fix the mounting plate 130 to the stop element 104 and on the other hand create a connection between a first stop element 104 and an opposite stop element 104 .

This double function is in the 9 easy to see, in which the overall structure, which was previously discussed, is shown again in a lateral sectional view. It is easy to see that the actuating mechanism 112 and in particular the fastening bushings 116 and the pinion 126 are arranged on the first stop element 104 arranged on the right. Both the mounting bushings 116 and the pinion 126 are designed to accommodate a connecting element. For this purpose, the pinion 126 is formed on a first bushing 150 which has a receiving space for a connecting element 132 . The connecting element is the square pin 132, which is mounted in a floating manner in the socket of the pinion 126. On the opposite second stop element 104' there is a second bushing 152 in the opposite direction, in which the square pin 132 likewise engages. The second bushing 152 is in this way with the locking tablet 114 connected such that rotation of the second bushing 152 causes actuation of the locking mechanism formed in the locking tablet 114 . Furthermore, the receptacle 120 for a tool is formed on the left-hand side of the second bushing 152 and is connected to this bushing in a rotationally fixed manner. The receptacle 120 protrudes through the second receptacle element 104' so that the locking mechanism can be actuated from this side.

Furthermore, connecting pins 154 are arranged on the second stop element 104`, which engage in the fastening sockets 116 and thus determine the position of the second stop element 104' relative to the first stop element 104. The stop elements 104, 104' can be displaced relative to one another along the first axis of rotation, which enables the actuating handle 100 to be adapted to the thickness of a door or a door leaf.

The structure of the actuating handle 100 described above makes it possible to arrange the entire mechanism of the locking device in a door leaf, so that the stop elements 104, 104' can finish smoothly with the surface of a door leaf. Only the sliding element 108 for actuating the locking device 106 protrudes from the first stop element 104 in addition to the handle 102 itself. This results in an overall very compact picture, since only a few elements protrude from the door leaf.

The invention is not limited to one of the embodiments described above, but can be modified in many ways.

For example, the sliding element 108 can also be arranged on the side or below the recess 118 for receiving the handle 102 . The specific configuration of the latching mechanism described can also be modified in such a way that the latching lug is arranged on the rotary slide 122 , while the opposing recesses are provided in the latching ring 124 .
