Abstract

A handle (30) operates an automotive door opening and closing mechanism, which has a lock cylinder (60) and key. The handle operation is via a lever (30) and rotation of the lock cylinder (60) action transfer to a pick-up (45). The pick-up (45) action is transferred to the lever (30) by a pushrod (50). The lever (30) has an adjustable bearing position (31, 11) which is determined by the pushrod (50) with respect to the lock cylinder (60) rotational position. The arrangement alters the lever operating ratios relative to a connector (40) to the lock.

Description

The invention is directed to a device specified in the preamble of claim 1. Art. In such devices, the handle is used in its operation to open the door when a release position is present. The lock cylinder is to convert the door lock between a securing position and this release position when it is rotated by means of a key. In the securing position of the door lock namely the aforementioned handle operation for opening the door is ineffective; the closed door remains closed. It is then the backup position of the door lock. Such reversals of the door lock between the backup and Entsicherungsstellung be triggered in the modern electromechanical keys and associated closures normally by electrical means, for example, provided by a remote control remote control. Use of the mechanical key is then required only in an emergency, if the electrical components or the electrical power supply in the vehicle fail.

Such devices therefore have two different actuating means for manual operation, namely the handle on the one hand and the key acting on the lock cylinder on the other hand. In some cases, e.g. in a "keyless entry", the lock cylinder and the key can be connected to form a unit which eliminates the need to insert and remove a key.

In such a known device (DE 44 45 320 A1) two separate link chains are required between the two actuating means and the door lock. The handle acts on an actuating lever, to which a first connection leading to the door lock is connected and, in the case of a handle actuation, releases the engagement of a trap provided on the door with a stationary closing element on the door frame. At the output of the lock cylinder, a further link chain is connected, which transfers the door lock in dependence on the key operation in the aforementioned safety and Entsicherungsstellungen. The two link chains require double space and must occupy certain positions in the door to each other.

In the known device of the type mentioned in the preamble (EP 0 692 595 A1, FIGS. 3 to 5), only a single link chain is used for both actuating means, that is, both for the handle and for the lock cylinder, which is designed as a Bowden cable. Such a Bowden cable consists of a cable transmitting the movement and of a hose enclosing the cable. The handle is followed by a transmission lever, to which then one end of the Bowden cable is connected. During the pivoting movement of the handle, a translatory movement of the Bowden cable takes place. The lock cylinder interacts here directly with the cable of the Bowden cable. A rotation of the lock cylinder by means of a key causes a rotation of the cable in the dormant hose.

In a device of another kind (DE 196 40 595 A1), in which the link chain also consists of a Bowden cable, there is no transmission lever which is connected between the handle and the cable of the Bowden cable. The lock cylinder engages at one end of the hose of the Bowden cable. In a rotational operation of the lock cylinder, one end of the hose is taken along with the cable therein, while the other end of the hose rests. When the key turn of the cylinder core no actuation of the handle takes place. The cable on the one hand and the hose of the Bowden cable on the other hand, are independent control means; the hose of the Bowden cable serves as a control means of the lock cylinder and causes via the cable received therein a reversal of the door lock between its securing and Entsicherungsposition.

In a further device, which also has no transmission lever between the handle and a door lock lead link chain (FR 2 766 226 A1), a pull rod is arranged between a lever of a door lock on the one hand and an actuatable by the handle angle-shaped control means. At the transition between the locking and unlocking position of the lock, the effective rod length changes. This is done by a wedge which passes between the control means of the handle and the physical end of the rod.

In another known device (GB 2 271 374 A), a cam is non-rotatably connected to the lock cylinder. The cam engages a designed as a Bowden link chain, which leads to the door lock. A manually operable handle only cooperates with a shoulder of the cam when the lock cylinder is in its unlocked rotational position. Then the Movement of the handle via the cable from the Bowden cable to the door lock forwarded. If the lock cylinder is transferred by a key into the other, secure rotational position, then the handle of the cam does not hit the shoulder, which is why the door lock then remains unactuated. The fuse and release does not take place behind the Bowden cable, in the area of the door lock, but at the cam of the lock cylinder, ie in front of the Bowden cable. A working stroke is forwarded by the Bowden cable only in the unlocked position of the cam, while in the secured position no working stroke is transmitted.

The invention has for its object to develop a reliable device specified in the preamble of claim 1 species, which avoids the aforementioned disadvantages. This is inventively achieved by the measures specified in claim 1, which have the following special significance.

The special feature of the invention is that by key rotation of the lock cylinder, the length of the lever arms are changed by the two-armed transmission lever. Because the length of the lever arms but determines the ratio between the handle and the link chain, resulting in a constant pivotal movement of the handle different strokes, which are forwarded via the link chain to the door lock. The lock cylinder thus acts indirectly on the link chain, namely by changing the arm lengths of the transmission lever. The link chain, however, is directly connected to the one arm of the transmission lever and changed during the rotation of the lock cylinder neither their effective length nor their course. Then the door lock over the length of the working stroke can clearly identify whether it is a control pulse of the lock cylinder or a control pulse of the handle, and reacts accordingly. For example, in an emergency, when the door lock is in a securing position where normally an operation of the handle is ineffective, by key operation of the lock cylinder and a first handle actuation a control pulse are continued, which transfers the door lock in its armed position. Then, when the handle is pivoted once again by the same angular amount, then the transfer member provides for a working stroke, which opens the door via the same link chain.

Fig. 15,

in analogy to Fig. 9 of the first embodiment, resulting in Fig. 14 further operating phase, where the handle has been brought into its operating position.

A first embodiment of the device according to the invention is shown in FIGS. 1 to 11 and described in detail below. A second embodiment of the device according to the invention is, subsequently, explained with reference to FIGS. 12 to 15 with reference to those components which are formed modified relative to the first embodiment. In other respects there is a correspondence between the two components, for which reason the preceding description of FIGS. 1 to 11 applies to the second embodiment of FIGS. 12 to 15.

At a dash-dotted lines in Fig. 1 indicated door 10, the first embodiment of the device according to the invention is fixed with its carrier 13, which carries and / or stores various components. These include first a here as a so-called "pull handle" trained handle 20 which is pivotally mounted at 21 in the carrier 13 and at its opposite free end of the handle 22 with the one driven arm 23 of a best recognizable by hatching in Fig. 3 lever 25 cooperates. In Fig. 3, drawn drawn, the illustrated by an auxiliary line 20.1 rest position of the handle 20 is shown. By pulling the handle 20 in the direction of arrow 26, the handle 20 enters the dash-dotted lines in Fig. 3 illustrated operating position 20.2. In this case, a first arm 33 of a bed actuating lever 30, also referred to as a transmission lever, is detected by a second driving arm 24 of the reversing lever, which is to be referred to below as the "input arm". In the case of handle operation 26, the input arm 33 arrives from its previous starting position 30.1, marked with the auxiliary line 30.1 in FIG. 4, in its actuating position 30.2 shown in FIG. 5 and dotted.

As can be seen in FIG. 2, the actuating lever 30 also has a second arm 34, which is to be referred to below as the "output arm". At the free end of the output arm 34 is connected via a hinge 35 a not shown in detail shutter leading link chain, which will be referred to as compound 40 hereinafter because of their special design. This connection 40 consists in the present case of the soul of a in Fig. 1 in its entire length recognizable Bowden cable 41 whose shell 42 is attached to a boom 43 of the carrier 13. In the above-mentioned normal case of Fig. 4 to 6 due to the mentioned handle operation 26 via the actuating lever 30, the connection point 35 of the connection 40 from the marked in Fig. 4 with 35.0 rest position in the recognizable from Fig. 5 operating position 35.1 transferred, their position also is drawn in Fig. 4. This results in the working stroke of the connection 40 illustrated by an arrow 36 in these figures.

A special feature of the device is that the actuating lever 30, as best seen in FIG. 2, two bearing pins 31, 32 has, which two of Fig. 4 apparent open bearing receptacles 11, 12 are assigned. As can be seen from Figs. 2 and 4, there is only one, the bearing pin 31 associated bearing seat 11 in a seated on the support 13 bearing cap 14, while the other bearing receptacle 22 at the free end of a arranged below this bearing cap 14 control member 50 is arranged. This control element 50 is highlighted in FIGS. 4 to 10 for better clarity by dot hatching. From Figs. 2 and 4 it is further apparent that the second bearing pin 32 in the carrier-side bearing cap 14, a longitudinal slot 15 passes through. In order to recognize the components located under the bearing cap 14, the bearing cap 14 is shown in phantom in its outline in FIGS. 4 to 11.

In the normal case of FIGS. 4 to 6, the elements 31, 11 determine a first bearing point for the actuating lever 30. A return force 16 acts on the output arm 34 of the actuating lever 30 and the input arm 33 rests against the point of engagement 28 of the driving arm 24 belonging to the deflection lever 25 from. The deflection lever 25 is also under the action of a recognizable from Fig. 3 restoring force 17. The former restoring force 16 comes from the Bowden cable 41 ago and strives to keep the connection 40 in its rest position 35.0 of Fig. 4. The other restoring force 17 is generated by a leg spring 27 which can be seen from FIG. 2, which acts on the reversing lever 25 and endeavors to hold its second arm 24 in the starting position of FIG. 4. Thus, the pin 31 is held in the bearing base 18 of the open receptacle 11, the bearing opening is covered at a sufficient distance from a stationary, belonging to the carrier 13 bearing cap 19. The cap 19 engages with a counter surface 29 in the longitudinal slot 15 behind the second bearing pin 32 a. In the rest position 20.1 of the handle, which leads to the starting position 30.1 of the input arm 33, a stop-like contact between the second bearing pin 32 and the counter surface 29 can take place.

The leg spring 27 can, as Fig. 3 illustrates, on the lever arm 23 for a return of the operated handle 20 in terms of the return arrow 26 'from its operating position 20.2 in its rest position 20.1, provide. This return takes place at the transition from Fig. 5 in Fig. 6. In Fig. 5, the actuating hand still attacks the handle. In Fig. 6, the hand has released the handle 20. Due to the restoring force 17 results in Fig. 6, a return stroke 36 ', the. Junction 35 the connection 40; the connection point 35 comes from its operating position 35.1 back to its rest position 35.0.

When the actuating lever 30 is rotatably mounted on its first bearing journal 31, which is illustrated in FIGS. 4 to 6 by points of the journal 31, the actuating lever results in the arm lengths of its output arm 34 and input arm designated in FIG. 4 with 30.1 and 34.1 33. This has an effect on the rotation of the actuating lever 30, illustrated by the arrow 51 in FIG. 4, through a specific transmission ratio. In the illustrated embodiment, the ratio of the lengths 34.1 of the output arm 34 to the length 30.1 of the input arm 33 may be about 1.4. The illustrated in Fig. 4 attack point 28 of the driving arm 24 from the lever 25 on the input arm 33 of the actuating lever 30 has the full actuating stroke 69 of the handle 20 of FIG. 3, a drive path 38, which is also shown in Fig. 4. Because of the existing transmission ratio then performs the connection 40 at the end of the output arm 34 the already described working stroke 36 and the recognizable from Fig. 6 return stroke 36 'from.

In the carrier 13 also a lock cylinder 60 is rotatably mounted; which can be rotated by a key not shown in detail between at least two rotational positions. At the inner end of the cylinder, the lock cylinder 60 has an eccentrically arranged to its cylinder axis cylinder pin 61, which is held by a spring 62, in a clarified by the auxiliary line 60.1 in Fig. 4 rotational position. This rotational position 60.1 is the so-called "zero position" of the lock cylinder 60. The spring 62 performs a dual function. The spring 62 is formed zwekelnkelig and has turns which act as a so-called pulse spring on the lock cylinder 60 and automatically after a key turn 63 shown in FIG. 7 again, as the reverse rotation arrow 63 'of Fig. 8, return to the zero position 60.1. This is the first function of the spring 62.

As shown in FIG. 4, a driver 45 is non-positively supported on the cylinder bolt 61 and is pivotally mounted on the carrier 13 by means of a bearing 44 arranged eccentrically to the cylinder axis. The driver 45 acts on the aforementioned control member 50 a. For better clarity, this control member 50 is highlighted in FIGS. 4 to 11 by dot hatching. The driver 45 here consists of an angle lever with two arms 46, 47, which are spring-loaded by the spring 62, as seen in Fig. 4, in the clockwise direction. This leads to the mentioned non-positive. Plant of which as drive arm 46 for the control member 50 acting arm of the driver 45 and the cylinder pin 61. The second, as the output arm 47 to be designated arm of the angle lever 45 has a fork 48, in which a pin 58 engages. The pin 58 is seated on the bearing seat 12 opposite end of the control member 50. The fork 48 and the guided therein displaceably pin 58 form a so-called "slotted guide" between the two components 45, 50th

In the zero position 60.1 of the lock cylinder according to FIGS. 4 to 6, the driver 45 with its output arm 47 assumes the zero position indicated by the auxiliary line 45.0. In this zero position via the mentioned connection 48, 58 of the spool 50 in a position so far withdrawn that at the above rotation 51 about the first bearing pin 31, the mentioned bearing seat 12 on the control member 50 at a sufficient distance from that in this rotation 51 ineffective second trunnion 32 is located. It can at best come to an apparent from Fig. 5, completely unimportant light touch with the second journal 32 when it is transferred during the rotation 51 from a dash-dotted line indicated here rest position in the pulled there drawn pivot position. This pivoting distance is determined by the angle of rotation of the actuating lever 30 between the two apparent from Fig. 4 starting and operating positions 30.1, 30.2.

When the handle 20 is released and the apparent from Fig. 6 return stroke 36 'is initiated, the second bearing pin 32 passes again by this distance 49 back to its drawn in Fig. 6 there drawn rest position by contact with the mating surface 29th the mentioned bearing cap 19 is marked. As shown in FIGS. 5 and 6 make clear, the longitudinal slot 15 in the indicated by dash-dotted bearing cap 14 for such a pivotal movement 49 of the second journal 32 is dimensioned sufficiently large; the second trunnion 32 moves freely. These ratios characterize the mentioned "normal case" on the device.

In modern devices, the securing position and Entsicherungsstellung the closure is controlled by an electronic key. In Fuse position is an operation 26 of the handle 20 ineffective, however, after unlocking the lock successfully. A mechanical actuation of the lock cylinder 60 via a key is normally not required. However, this is necessary if, as already described, the electrical energy supply or the electronic components fail. Then one is dependent on a so-called "emergency operation" of the closure by means of the mechanical key. Then, the lock cylinder 60, as already mentioned and is illustrated in Fig. 7, a key rotation 63 subjected, which is transferred to the cylinder pin 61 from the dash-dotted line indicated zero position 60.1 in the pulled-drawn and marked by an auxiliary line 60.2 Entsicherungsstellung 60.2. This cylinder rotation 63 is not forwarded in the invention, as usual, by its own link chain to the closure, but through the same link chain, via which the manual operation 26 of the handle 20 takes place.

This is achieved in that the driver 45 co-pivoted by the lock cylinder 60 via the cylinder bolt 61 acts on the actuating lever 30 in a special way via the control member 50. By means of the output arm 47 from the driver 45, the control member 50 is displaced from an ineffective position, which is indicated by the auxiliary line 50.1 at its pin 58, to the effective position indicated in FIG. 7 by the corresponding auxiliary line 50.2 , The control member is shifted by the distance 53 indicated in FIG. 7 by an arrow. Namely, the control member 50 consists of a slider which is assigned a guide with a guide surface 54 on the carrier 13. Mitbeweglich with the slider 50 is a pawl 65 which is provided with a latching nose 66. The pawl 65 is force-loaded by a spring 39 already indicated in FIG. 2 in the sense of the force arrow 74 of FIGS. 4 and 8. The Mitbeweglichkeit the pawl 65 results from their storage on the pin 58 of the control member 50, by which the pawl 65 is pivotally movable. In the normal case, as shown in FIGS. 4 to 6, the latching nose 66 comes to the guide surface 54 for support and is therefore initially ineffective. Then connected to the pawl 65 control member 50 in the direction of the arrow 53 of FIG. 7 is displaceable. The guide surface 54 on the carrier 13 provides a sliding guide of the latching nose 66. This changes when the conditions illustrated in FIG. 7 are present. In Fig. 7, the control member 50 has moved by the distance 53 and reached its already mentioned effective position 50.2. Then, the locking lug 66 can snap in the sense of the movement arrow 76 behind a stationary shoulder 55, which belongs to the carrier 13 due to the already mentioned force load 74. It comes to a clarified by the arrow 75 in Fig. 7 torque effect of the spring 39 on the pawl 65. Thus, the effective position 50.2 of the control member 50 via the pawl 65 is initially secured. The seated at the front end of the control member 50 bearing receptacle 12 is moved against the second bearing pin 32, and makes it together with the counter surface 29 on the bearing cap 19 capable of rotation. Now, if an operation 26 of the handle 20 takes place, which again transfers the input arm 33 of the actuating lever 30 from its initial position 30.1 of Fig. 1 in the operating position 30.2 of Fig. 8, then now takes place a rotation 52 about the second bearing pin 32. The effectiveness of the journal in Figs. 7 to 9 is again highlighted by puncturing. This is because the bearing effective position of the second bearing receptacle 12 in FIG. 7 fundamentally excludes the pivoting movement 49 of the second bearing journal 32 which is still possible in the normal case according to FIG. 5. The recognizable in Fig. 5 free space in the longitudinal slot 15 of the dot-dashed bearing cap 14 is blocked in the operative position 50.2 of the control member 50. In contrast, as can be seen in FIGS. 8 and 9, the first bearing journal 31 moves freely in its open bearing receptacle 11 from the dot-dashed bearing cap 14 in the sense of the pivoting arrow 56 there. In FIGS. 7 to 9, the first bearing journal 31 is not bearing-effective.

Fig. 8 shows, as already described above, the situation of the lock cylinder 60 after releasing the key. Due to the mentioned restoring action of the spring 62 acting on it, the lock cylinder 60 is automatically returned to its zero position 60.1 via its cylinder bolt 61 from a release position 60.2 of FIG. 7. There is a reverse rotation 63 'of the lock cylinder 60 instead. Nevertheless, the position of the control member 50 remains in the operative position 50.2. This results from the above-described, still existing locking engagement of the latching nose 66 behind the stationary shoulder 55 from the carrier 13. It therefore remains the second bearing 12, 32 on the actuating lever 30 are made; There is a rotation 52 about the bearing pin 32nd

FIG. 8 also shows the first phase of the handle operation 26, where the handle 20 has performed about 90% of its actuation stroke 69 of FIG. This can be recognized by an intermediate position of the input arm 33, identified there by the auxiliary line 30.3, from the actuating lever 30. The connection point 35 of the connection 40 leading to the lock has moved by a distance 71 from its rest position 35.0 in FIG. 7 into an intermediate position marked 35.2 in FIG. 8. Already this intermediate position 35.2 differs, as can be seen by the mark in FIG. 8, from the normally occurring actuating position 35.1 of FIG. 5. This is due to the other transmission ratio of the actuating lever 30 resulting in the emergency operation case of FIGS. 7 to 11.

After further completion of the handle operation 26 over the remainder of the full actuating stroke 69 of FIG. 3, the input arm 33 of the actuating lever 30 finally comes into its actuated position 30.2 of FIG. 9. Then, the connection point 35 of the connection 40 has reached the position indicated by 72 in FIG. 9 marked end distance 72, which leads to the 35.3 in Fig. 9 designated emergency operation position 35.3. In an emergency, the connection end 35 of the connection 40 has then moved in total around the large working stroke 70 shown in FIG.

The changed transmission ratio is due to the effective in an emergency of Fig. 7 other arm lengths of the two arms 33, 34 from the actuating lever 30. The arm lengths are now related to the second bearing pin 32 and have the marked in Fig. 7 with 33.2 and 34.2 lengths on. The transmission ratio between the length 34.2 of the output arm 34 to the arm length 33.2 of the input arm 33 may now be 2.2. In any case, the working stroke 70 is substantially greater in an emergency than the working stroke 36 in the normal case. These differences between 70 and 36 are detected by the shutter and perform the corresponding functions. In the small working stroke 36, the shutter detects that a "normal case" exists and opens the door. But when the large stroke 70 takes place, so the shutter detects the "emergency" and leads the hitherto in securing position closure in his. Unlocking position The then actuation of the handle opens the door again. These However, release movement can also be carried out during the last phase of the handle operation 26 in the event of an emergency. The closure has, for example, suitable sensors, which respond to the differences in the working stroke 36, 70. As illustrated in FIG. 7, the stroke movement leads to a drive path 38 of the input arm 33, which corresponds to the normal case of FIG. 4, from the actuating lever 30. In both cases, namely in the normal case according to FIGS. 4 and 5 on the one hand and in an emergency, according to FIG to 9, the identical operating stroke 69 shown in FIG. 3 takes place.

In the final phase of the handle operation 26 in an emergency, as shown in Figs. 8 and 9, an automatic reset of the device takes place in the normal case of Fig. 4. For this purpose, the pivoting movement 52 of the actuating lever 30 is utilized. In the present case, there is provided a cam 37 which, in the intermediate position 30.3 shown in FIG. 8, just touches a control surface 68 on the pawl 65. Upon completion of the remaining operating stroke 69 of FIG. 3, the cam pushes. 37, the latching nose 66 of the latch from their engagement behind the stationary. Shoulder 55 from the carrier. 13 away, which is illustrated by the movement arrow 77 in Fig. 9. The pawl 65 no longer holds the control member 50 in its operative position. The restoring force 57 exerted by the spring 62 on the driver 45, illustrated in FIG. 9 by the force arrow 57, moves the control member 50 back into its inoperative position 50.1 in the sense of the return movement arrow 59 because of the operative connection 48, 58.

The result of this return movement 59 can be seen in FIG. The control member 50 has now released with its bearing seat 12, the second bearing pin 32. In Fig. 10, the handle 20 has been released, which is why it performs its return movement 26 'of Fig. 3 due to the aforementioned restoring forces. In FIG. 10, a partial return stroke of the connection point 35 takes place around the initial distance 73 indicated by the arrow in FIG. 10 up to the return stroke intermediate position designated by 35.4. Already it is because of the mentioned restoring force 16 of the first bearing pin 31 in its storage effective position in its associated bearing seat 11 of the indicated therein dash-dotted bearing cap 14 come. Already in Fig. 10, as was emphasized by a dot hatching, again the first bearing pin 31 rotationally effective, while the second Journal pin 32 released from the control member 50 and is no longer bearing effective. The second journal 32 has moved back in FIG. 10 from its dash-dotted lines, in Fig. 9 still bearing effective rotational position freely in the longitudinal slot 15 in the sense of the pivot arrow 49 (in analogy to Fig. 5), although the actuating lever 30 with its input arm 33rd is still in a rear pivot intermediate position 30.4 in Fig. 10.

In Fig. 10 are again the bearing conditions of the normal case of Fig. 4 to 6 before. Therefore, the above-described return stroke intermediate position 35.4 of the connection terminal 35 may be identical to the operating position 35.1 described in connection with FIGS. 5 and 6. The further reverse rotation of the control member 50 up to its recognizable in Fig. 11 starting position 30.1 is again by rotation 51 of the first journal 31. The connection port 35 moves along the illustrated by the arrow 36 'in Fig. 11 Endstrecke 74 of the return stroke back until the connection 40 has again reached its rest position 35.0 of FIG. 11. This return stroke 36 'corresponds to the return stroke which is normally recognizable in accordance with FIG. 6.

As can be seen from FIGS. 8 to 11, an alternate mounting of the actuating lever 30 takes place in an emergency. During the power stroke 70 shown in FIGS. 7, 8 and 9, the second journal 32 is effective. However, during the return stroke, an automatic reversal of the rotary bearing takes place on the first bearing journal 31 of the actuating lever 30. The device automatically resets itself to the conditions of the normal case from the circumstances which characterize the emergency.

The second embodiment of the device according to the invention shown in FIGS. 12 to 15 differs from that of the previously described first embodiment substantially in two respects. First, the control member is formed in this case as a pivot member 50 '. Further, a thrust member 45 'is used as a driver, which is longitudinally displaceable in addition to the local lock cylinder 60 in a stationary guide 78 in the course of the operations to be described in the sense of the arrow 79 visible in FIG. The carrier 13 shown in the first embodiment is, for better clarity, in the second embodiment of Figs 15 drawn largely invisible; the reference numbers of the first exemplary embodiment have been used to denote the remaining elements, for which reason the same reference numerals have been used for their designation. In that regard, the previous description applies. It is only to be discussed on the differences.

The thrust member 45 'has at its one end a recess 88 which is oriented transversely to the aforementioned longitudinal displacement direction 79 and in which the eccentric cylinder pin 61 already described in the first embodiment engages. In FIGS. 12 and 13, the "zero position" of the lock cylinder 60 marked by the auxiliary line 60.1 is present, which, as in the first exemplary embodiment, is effected by corresponding return springs. At the other end of the thrust member 45 ', a connecting rod 82 is connected via a pivot point 83. The opposite rod end is connected via a further pivot point 84 on the pivot member 50 '. About the connecting rod 82, the respective position of the thrust member 45 'is transmitted to the pivot member 50', which thereby can be brought into different defined pivot positions.

The pivoting part 50 'is pivotally mounted on the actuating lever 30. For this purpose, the seated on this operating lever 30 second bearing pin 32 is used. For this purpose, the pivoting part 50 'has a bearing bore, which in the present case generates a closed bearing receptacle 12' for this second bearing journal 32. The pivoting part 50 'is first associated with a stationary guide segment 80, which is part of the carrier already mentioned several times and is indicated for clarity reasons of the underlying components in FIGS. 12 to 15 only dash-dotted lines. The guide segment 80 serves not only to guide the pivoting part 50 'in the between Figs. 12 and Fig. 14 resulting, illustrated by an arrow 90 rotation, but also allows an apparent from Fig. 13 lifting 89 of the pivot member 50'.

The pivoting part 50 'is also associated with a stationary stop 81, which has an angle 85 and, as already mentioned, part of not in The Fig is drawn with carrier. Another component of the carrier is a bearing receptacle 11, which is also open here, for the first bearing journal 31 also seated on the actuating lever 30. The bearing receptacle 11 results from the bearing shell 91 marked by dash hatching in FIGS. 12 to 15.

FIG. 12 shows, as already indicated in the figure designation, the rest position of the local handle 20, which is viewed in FIGS. 12 to 15 from the inside of the door. It is also in this case a so-called "pull handle" with a by the dashed line 21 'in Fig. 12 illustrated pivot axis at one end of the handle. The other. Handle end 22 is again in clutch engagement with a first arm 23 of a two-armed reversing lever 25, which has the likewise dash-dotted lines in Fig. 12 illustrated vertical axis of the lever 92 in the carrier not shown. The reversing lever 25 is normally held in the starting position shown in FIGS. 12 and 14 by return springs not shown in detail, which is present when the handle 20 is in its rest position shown in these figures. If in this case the lock cylinder 60 is in the already mentioned zero position 60: 1 of FIG. 12, then takes the pivot member 50 'the apparent from Fig. 12 pivot position, where a on the pivot member 50' located Anlagease 86 already a distance 87 to his Stop 81 occupies. The Anlagease 87 is rotated away from the angle profile 85 of the stop 81.

The operating state of FIG. 12 thus corresponds to FIG. 4 of the first exemplary embodiment. If, in the operating state of the rest position shown in FIG. 12, the handle 20 has been pulled about its vertical axis 21 ', the state shown in FIG. 13 is reached, which is analogous to the operating position of the handle of FIG. 5 in the first exemplary embodiment. As is apparent from Fig. 13, the handle 20 takes because of its coupling at 22 the bell crank 25, whereby the input arm 33 of the actuating lever 30 is taken over the provided on its second arm 24 point of attack 28 and thus to a rotation 51 of the pivot member 50th 'comes to the bearing elements 31, 11. In this pivoting 51, the swivel-mounted at 32 swivel part 50 'is taken and it comes to the aforementioned lifting 89 of the guide 80. This lift-off 89 is not by the guide segment 80 opposite stop 81 with special needs; the co-rotating with the operating lever 30 pivoting part 50 'goes unhindered past the stop 81. During this rotation 51, the pivoting part 50 'via the connecting rod 82 with the thrust member 45' remains in articulated connection.

Also in the second embodiment of Fig. 12 to 15, the connection to the lock not shown in detail from a Bowden cable 41, the core 40 engages at a connection point 35 of the second arm 34 from the actuating lever 30. Also in this case, the force acting on the core 40 restoring force 16 ensures the effectiveness of the first bearing elements 11, 31. This is again illustrated in Fig. 12 and 13 by Punktschraffur the first journal 31. In the rest position of Fig. 12 results again, in analogy to the first embodiment, a rest position 35.0 of the connection point 35, which merges in the operating position of the handle 20 of Fig. 13 in there marked with 35.1 operating position. In this normal case, the Bowden cable 41 undergoes a recognizable from Fig. 13 stroke 36. This relatively small stroke 36 causes the associated closure that the shutter opens and the door can be opened.

As was explained in the first exemplary embodiment with reference to FIG. 7, the conditions shown in FIG. 14 result when a closure in the locking position must be opened by a mechanical key in the event of an emergency. This is done by a mechanical key not shown here, which is inserted into the lock cylinder 60 of Fig. 14 and thereby the cylinder pin 61 is rotated from its dash-dotted lines in Fig. 14 illustrated neutral position 60.1 in the armed with 60.2 Entsicherungsstellung. Because of the coupling of the cylinder pin 61 in the recess 88, the thrust member 45 'is taken in this rotation 63. It comes to the aforementioned longitudinal displacement 79 of the thrust member 45 'in the guide 78, whereby, via the connecting rod 82 of the pivot member 50' in its guide segment 80 is rotated. This results in a support of the system nose 86 from the pivoting part 50 'at the angle profile 85 of the stopper 81. Fig. 14 shows, in analogy to Fig. 7 of the first embodiment, the rest position of the handle 20. The connection point 35 of the connection 40 is located in Fig. 14 again in the rest position 35.0, which was already present in Fig. 12. If, starting from Fig. 14, the handle 20 is actuated, then arise in this emergency, the apparent from Fig. 15 ratios.

In Fig. 15, in the same way as in Fig. 13, the input arm 33 has been taken by the actuating lever 30 via the rotation of the reversing lever 45 about its lever axis 92. Because now the pivot member 50 'between the stop 81 and its guide segment 80 has been set, now takes place a rotation of the actuating lever 30 about the second bearing pin 32 instead. The bearing bore 12 'is now effective, together with the bearing pin 32. The rotation 52 of the actuating lever 30 now takes place at a different location 12 ', 32, than the rotation 51 in the preceding normal case of Fig. 13 between the first bearing 11, 31. The effectiveness of this second bearing pin 32 is shown in FIGS. 14 and 15 again illustrated by dot hatching.

In an emergency, according to FIGS. 14 and 15, the actuating lever 30 has a different transmission ratio than in the normal case of FIGS. 12 and 13. Starting from its rest position 35.0, the connection point 35 moves up to the end position marked 35.3 in FIG. In this emergency, there is a large stroke 70. As in the first embodiment, this is registered by the associated closure, which is connected via the connection 40 to the actuating lever 30 at 35. This unlocks the latch.

If you release the key, the lock cylinder 60 can be moved back by its return spring, not shown in detail from its armed position 60.2 of Fig. 15 in its zero position 60.1 of FIG. The like happens when the handle 20 is released. The closure is unlocked and therefore the original conditions of FIG. 12 again arise. By re-actuating the handle 20, as already described in connection with FIGS. 12 and 13, the closure is opened.

Also in this case, as in the first embodiment, locking means may be provided which, in analogy to FIGS. 7, 8 and 9 of the first embodiment, in an emergency, the pivot member 50 'first in his hold bearing-forming position of Fig. 14 and 15 and release only at the second handle operation.
