The invention comprises a normal device 10 and which can be actuated in the normal case an emergency device 20 to be operated in an emergency, of which in the drawings only the actuating means are shown in longitudinal section. Both devices 10, 20 have a common combination handle 30.

The normal device comprises a microswitch 11 with a switching element 12, which converts the switch 11 into two switch positions. The switch 11 is with an electric motor, not shown, electrically connected, on which he acts at least in one of the two switching positions. On the combi handle 30 acts a restoring force illustrated by force arrows 13. The Restoring force normally acts with outer shoulders and counter shoulders 14, 15 together, whose positioning will be described in more detail. in the 1, the combination handle 30 actuates with its inner surface 32 the switching element 12 does not, with which the switch is in its first switching position located. The associated position of the switching element 12 is indicated by an auxiliary line 12.1 in Fig. 1 characterizes and is hereinafter referred to as "rest position".

In Fig. 3, the combination handle 30 on its outer surface 31 in the sense of Force arrow 33 have been pressed. This made the switching element 12 of the switch 11 transferred to the position indicated by the auxiliary line 12.2. In this situation 12.2 is the switch 11 in its second switching position, in which the mentioned motor the lock is operated. This situation 12.2 thus proves as the "operating position" of the switch 11.

In the invention, the emergency device 20 with its operating means is one the normal device 10 integrated, which will be described in more detail. to Emergency device first include traction means 40, which in the present case consist of a Bowden cable exist, the jacket 42 at one end of the housing 18 of the device is attached. His rope 41 is a multi-part on an output member 22 Actuator chain 21 attached, which is located inside the housing. The Input link 28 of this link chain 21 is a slide, its appearance and Function will be described in more detail. Acts on this input member 28 a spring load 23 illustrated by a further force arrow Spring loading 23 ensures that schematically indicated outer stops 24 and counter stops 25 the traction means 40 normally in one through the auxiliary line 22.1 Hold the "zero position" marked in Fig. 1. In this zero position 40.1 the traction means 40 are at rest and are ineffective for the lock.

If the input member 23 is actuated against its spring load 23, it will Traction means 40 in its position indicated by the auxiliary line 40.2 in Fig. 5 transferred, which will hereinafter be referred to as "working position". Through this Movement of the traction means 40, the lock is mechanically operated and e.g. from one Locked position transferred to an unlocked position. The one for that required movement path 43 is marked by an arrow in FIG. 5. This Movement 43 is also caused by the combination handle 30, which thus not only to operate the normal device 10, but also to operate the Emergency device 20 is useful. To this end, the invention proposes the following structural Measures before.

The input member 28 of the emergency device 20 is also a carrier for the switch 11. 1 marked with the arrow 19 in FIG Switching element 11 is aligned with the arrow 29 in FIG. 5 illustrated direction of movement 29 of the input member 28. Because of the Formation of the input member 28 as a slide mentioned is this movement 29th a translational longitudinal movement of the input member 28 in the housing 18. Both Directions 18, 29 are in turn in alignment with the direction of actuation Combi handle 30. This direction of actuation is shown in FIG. force arrow 33 already mentioned determined. It is worth noting that the restoring force 13 of the combination handle 30 is smaller than the spring force 23 of the input member is trained. Both forces 13, 23 are rectified and act on the combination handle 30, but only occasionally, as follows from the following.

The combination handle 30 is a push button in the present case, one with 35 in FIG. 1 marked bowl shape. The outer surface 31 of the bowl bottom serves as 3 and 5 show, as a manual actuation surface of the button 30, the Restoring force 13 is generated by a compression spring 34, which is at one end on the Inner surface 32 of the cup base 36 is supported. The other end of the compression spring 34 is located on the slide 28 of the emergency device 20. For this purpose, the slide 28 is as follows trained in a special way.

The slider is designed as a sleeve 45, which has a partition 44 inside the sleeve has. The aforementioned switch 11 is attached to the outside 46 of the sleeve 45 and protrudes into the inside of the compression spring 34. This sleeve outside 46 also serves to support the other end of the compression spring 34.

Both the cup-shaped 35 button 30 and the sleeve-shaped 45 slide 28 are longitudinally displaceable together in the housing 18. As can be seen from Fig. 1 the cup side wall 37 of the button 30 on the one hand and the sleeve wall 47 the slider 28 on the other hand telescopically in some areas. 2 is too see that the mentioned outer shoulders 14 and counter shoulders 15 in this Range. In Fig. 2 this is schematically by an axial guide in the cup side wall 37, which defines the shoulder 14, and one engaging therein Illustrates pin on the sleeve wall 47, which the counter shoulder 15th generated.

The combination handle 30 is in the invention between three with the auxiliary lines 30.1 to 30.3 in Figures 1, 3 and 5 positions shown axially movable. In Fig. 1 lies an "external position 30.1" of the combination handle 30. Not just the button 30, but also the slider 28 positively connected to it are located in it extreme extension position, which is caused by the forces 13, 23 and outer shoulders 14, 15 and stops 24, 25 is determined. As already mentioned switch 11 is not actuated and is in its rest position 12.1. The traction means 40 are also in their inactive zero position 40.1.

After a slight actuation 33 according to FIG. 3, the combination handle 30 comes in an intermediate position 30.2 against the action of the restoring force acting on it 13. A first stage 51 of actuation 33 takes place. The slider 28 of the Emergency device 20 initially remains at rest because it is below the much higher Spring load 23 stands. As already mentioned, the switch in FIG. 3 is in its actuation position 12.2, while the traction means 40 of the emergency device 20 always is still in its zero position 40.1. At pressure 33, the remove outer shoulders 14 of the counter shoulders 15 shown in FIG. 2, but there are 4 recognizable inner shoulders 16 of the combination handle 30 Counter shoulders 17 of the slide 28 to the system. This is shown schematically in FIG the front end (for 16) of the bowl side wall 37 and through a step (for 17) in the Sleeve wall 47 illustrated by the slider 28. The bottom wall 36 of the Cup-shaped combination handle 30 bounded with the outside 46 of the sleeve partition 44 a remaining distance 39 which is greater than / equal to the overall height of the switch 11 plus a possible remaining length of its switching element 12 that actuates it.

Only when actuating 38 with greater force, which is greater than the spring load 23 of the slide 28, there is also a longitudinal movement of the slide. This pulls the traction device into the already mentioned working position 40.2 from FIG. 5 transferred. The combination handle 30 is now in its inner position 30.3. Due to the impact of the already in connection with FIGS. 3 and 4 described inner shoulders 16 and counter shoulders 17 remains with the high pressure 38 the remaining distance 39 between the bottom wall 39, the Received cup-shaped combination handle 30 and the partition 46. The switch 11 and its depressed switching element 12 are protected.

As already mentioned, the combination handle occurs at the first actuation stage 51 30 between Fig. 1 and 3 to no change in the investment effect of outer stops 24 and counter-stops 25. This only changes in the second Actuation level 52 at the transition from Fig. 3 to Fig. 5. Now inner Stops on the slide 28 and inner counter-stops 27 on the housing 18 themselves touch and limit actuation 52. Sitting on the inside 48 of the partition a plunger 49 pointing axially in the direction of movement 29 of the slide 28, which with one arm 53 of a two-armed bell crank 50 cooperates. The Deflection lever 50 is mounted in a pivot bearing 55 inside the housing 18. The other lever arm 52 is with its free end in the already mentioned Output link 22 of the actuator chain 21 articulated. By pressing the second stage 52, movement 43 of the traction rope already described occurs 41st

In addition to the housing 18 there is a lock cylinder 56 with a Cylinder housing 57 and a cylinder core 58 which has a key channel 59 having. As indicated, there are 58 tumblers in the cylinder core corresponding locking grooves cooperate in the cylinder housing 57 and by one the key associated with the lock cylinder 56, not shown, can be actuated are. With the key 60, the cylinder core 58 of the locking cylinder 56 can be transfer between two positions. In the locked position of the locking cylinder 56 the handle 30 is blocked or set ineffective. The one from the associated lock the locked flap cannot be opened by unauthorized persons. The authorized person has the key and, if the flap is to be opened, can Transfer lock cylinder 56 to its release position. Then the combi handle 30 freely movable, both in the first stage 51 for motor Opening the lock or, in an emergency, two-stage 51, 52 according to FIG. 5 to open mechanical way to open the lock.
