The invention is illustrated below with the aid of a schematic illustration gene explained in more detail to exemplary embodiments. Show it

Fig. 1 to 4 a first type of locking device in different phases of operation and

FIGS. 5 and 6, a second type of a Verriegelungsvor direction in different Betriebspha sen.

Referring to FIGS. 1 to 4 1 comprises a locking device comprising a lock housing 2, in which the essential components Ver lock-out device 1 are accommodated. The lock housing 2 with the individual parts contained in it is intended for installation in a corresponding receptacle on the lock side folding surface of a door leaf 3 . In the installed position, the locking device 1 serving as an additional locking device is arranged at a distance from the central main locking device ( not shown) at the upper corner of the door leaf 3 .

In the interior of the lock housing 2 , an electric drive motor 4 which is reversible in its direction of rotation is mounted in a stationary manner. The drive motor 4 is drive-connected to a profile shaft 6 via a spur gear 5 . The profile shaft 6 has egg NEN hexagon cross-section and is mounted in vertical alignment with means of a lower bearing 7 on an intermediate wall 8 of the lock housing 2 and by means of an upper bearing 9 on an upper outer wall 20 of the lock housing 2 in the axial and radial directions.

A gear spindle 11 as a further part of the motor drive to the locking device 1 is designed as a sleeve-like hollow spindle and is displaceable in the axial direction, illustrated by a double arrow 12 , on the profile shaft 6, which is stationary in this direction. The axial penetration of the gear spindle 11 has a cross-sectional shape corresponding to the profile shaft 6 hexagon cut. In the direction of rotation of the profile shaft 6 about an axis of rotation 27 there is consequently a positive connection between the profile shaft 6 and the gear spindle 11 . At an externally toothed axial section 13 of the gear spindle 11 is connected on the one hand an outer smooth-walled upper axial end section 14 and on the other hand also a smooth-walled lower axial Endab section 15 of the profile shaft 6 . Each with the inner ring, a ball bearing 16 on the upper axial end portion 14 and a ball bearing 17 on the lower axial end portion 15 of the Ge drive spindle 11 are attached. An annular rubber buffer 18 sits below the lower end of the gear spindle 11 on the intermediate wall 8 of the lock housing 2 and surrounds the profile shaft 6 with a radial distance. A pressure plate 19 lies in the area of the upper axial end portion 14 of the gear spindle 11 on the outer ring of the ball bearing 16 attached there. The pressure plate 19 is penetrated by the diameter-reduced part of the upper axial end portion 14 of the gear spindle 11 , which protrudes into the interior of an energy storage device in the form of a coil spring 20 . With its end remote from the pressure plate 19 , the helical spring 20 rests against an outer flange 21 of an end cap 22 which is pushed onto the upper end of the profile shaft 6 . The end cap 22 receives a cylindrical end pin 24 of the profile shaft 6 with a bearing eye 23 which is circular in cross section. A hülsenar term length section 25 of the end cap 22 surrounds a cross-sectionally hexagonal part of the profile shaft 6 with radial play and thus avoiding a positive connection. Inside the end cap 22 results in the region of the transition of the hülsenar term length section 25 to the bearing eye 23, a radial step surface 26 on which the profile shaft 5 is supported in the axial direction.

On its externally toothed axial section 13 , the gear spindle 11 meshes with a counter-toothing element in the form of a ring gear segment 28 . The latter is integral with a bolt 29 and is mounted about a with the axis of rotation 27 of the transmission spindle 11 intersecting the rotational axis 30 rotatably mounted on the lock housing. 2 Through an opening 31 in a union wall 32 of the lock housing 2 and through an opening 33 in a side wall 32 of the lock housing 2 cover the and with the door leaf 3 screwed forend rail 34 , the bolt 29 about the axis of rotation 30 between egg ner Open position within and a closed position outside of the lock housing 2 can be pivoted back and forth. In a known manner, the bolt 29 is assigned a bolt, not shown, abutment on a fixed frame of the door leaf 3 , also not shown. As usual, the thickness of the bar 29 increases in the transverse direction of the drawing plane of FIGS. 1 to 4 starting from the free end of the bar 29 . The resulting wedge shape of the bolt 29 causes that with the movement of the bolt 29 into the closed position of the door leaf 3 due to the interaction of the bolt 29 with the associated bolt abutment more and more pressed against the fixed frame.

A support pin 35 is attached to the ring gear segment 28 and extends there parallel to the axis of rotation 30 of the ring gear segment 28th Adjacent to both sides of an upper leg 36 and a lower leg 37 of a pivotable on the axis of rotation 30 of the ring gear segment 28 seated leg spring 38th

Another support pin, namely a support pin 39 , is found on a two-armed lever in the form of a rocker switch 40 . The rocker switch 40 is rotatably mounted on the lock housing 2 about an axis of rotation 41 . A lower lever arm 42 of the rocker switch 40 ends in a projection 43 . A switching cam 44 is attached to the lower lever arm 42 . This is assigned to a push button 45 of a microswitch 46 . The microswitch 46 is in a controlling connection with the drive motor 4 of the locking device 1 .

An upper lever arm 47 of the rocker switch 40 forms a latching end 48 . Associated with the latching end 48 of the upper lever arm 47 is a pawl 49 of a locking device 50 made of magnetic material. The pawl 49 is held on the lock housing so as to be pivotable about an axis of rotation 51 and can be rotated by means of a switching spring 52 . An electromagnet 53 is arranged adjacent to the pawl 49 . A drive rod 54 is guided on the inside of the side wall 32 of the lock housing 2 in the direction of a double arrow 55 and is in drive connection with a panic lock, not shown. In a known manner, the drive rod 54 can be displaced in the direction of the double arrow 55 by rotating the locking cylinder of the panic lock. At its upper end, the drive rod 54 carries a switch cam 56 ( FIG. 4).

The operation of the locking device 1 is described below as follows:

Fig. 1 shows the locking device 1 in its initial state at the unlocked door leaf 3. The gear spindle 11 assumes its lower end position in the axial direction 12 and lies on the rubber buffer 18 . The bolt 29 is pivoted into the open position. The seated on its axis of rotation 30 leg spring 38 is supported with its legs 36 , 37 under tension on the one hand on the support pin 35 of the Zahnkranzseg element 28 and on the other hand on the support pin 39 of the Schaltwip pe 40 . As a result, the lower lever arm 42 of the switching rocker 40 is acted upon in the direction of the gear spindle 41 . The pawl 49 of the locking device 50 lies loosely on the latching end 48 of the upper lever arm 47 of the rocker switch 40 under the effect of its weight.

If the door leaf 3 is now transferred to its closed position and then locked to the fixed frame by means of the main lock, not shown, a conventional control device comes into action; as described for example in DE 298 05 821 U1. Triggered by the locking of the main lock, the drive motor 4 is then started with counterclockwise rotation. About the spur gear designed as a reduction gear 5 , the profile shaft 6 and with it the positively seated gear spindle 11 is thus set in a rotational movement about the axis of rotation 27 . Because of the interaction of the teeth of the externally toothed axial portion 13 of the gear spindle 11 with the serrations of the gear segment 28, the gear spindle 11 moves in its rotational movement to the toothed ring segment in the axial direction from the initial position shown in FIG. 1 upwards. The ring gear segment 28 is supported in FIG. 1 clockwise on the side wall 32 of the lock housing 2 and can consequently form an abutment for the gear spindle 11 moving in the axial direction.

Connected with the upward movement of the gear spindle 11 is a compression of the coil spring 20 impacted by this on the pressure plate 19 and thus a charging of this energy storage. In an intermediate position during its axial displacement upwards, the gear spindle 11 is shown in FIG. 2 ge.

With continued rotation of the drive motor 4 , the gear spindle 11 passes with its lower end or with the Kugella ger 17, the projection 43 on the lower lever arm 42 of the rocker switch 40th Actuated by the prestressed leg spring 38 via its upper leg 36 on the support pin 39 , the rocker switch 40 can pivot counterclockwise, starting from the conditions according to FIGS. 1 and 2, and thereby the projection 43 on the lower lever arm 42 of the rocker switch 40 is behind reach the lower end of the gear spindle 11 or the outer ring of the ball bearing 17 . At the same time, the upper lever arm 47 of the rocker switch 40 assumes a pivoting position in which the pawl 49 of the locking device 50 can latch with the latching end 48 of the upper lever arm 47 .

The pivoting of the lower lever arm 42 of the rocker switch 40 in the counterclockwise direction also results in a lifting of the switching cam 44 attached to the lower lever arm 42 from the pusher 45 of the microswitch 46 . The microswitch 46 is thereby switched and gives a switching pulse to the drive motor 4 , which consequently reverses its direction of rotation and now rotates clockwise. The direction of rotation of the profile shaft 6 and of the gear spindle 11, which is displaceably guided in the axial direction 12, changes accordingly. The latter sits from the previously compressed coil spring 20 in the Abbil applications acted down with the outer ring of Kugella gers 17 on the projection 43 of the lower lever arm 42 of the rocker switch 40 . The entire pressure force exerted by the helical spring 20 is accordingly introduced into the lock housing 2 via the rocker switch 40 and its axis of rotation 41 . With the reversal of the direction of rotation of the drive motor 4 , ie by switching the motor drive of the locking device 1 , the initial operative connection of the drive motor 4 and coil spring 20 is replaced by an operative connection of the drive motor 4 and bolt 29 .

As a result of the reversal of rotation of the drive motor 4 and the associated direction of rotation of the gear spindle 11. Namely, the gear segment 28 existing with the latch 29 due to the between the ring gear segment 29 and the gear spindle 11 tooth coupling, starting from the position shown in FIGS. 1 and 2 in the counterclockwise direction about the Axis of rotation 30 rotates ge. After the gear spindle 11 is placed on the projection 43 of the lower lever arm 42 via the outer ring of the ball bearing 17 acting as an axial bearing, its rotational movement is countered by only a slight frictional resistance. The bolt 29 pivots over the ring gear segment 28 driven through the opening 31 in the side wall 32 of the Schloßgehäu ses 2 and the opening 33 in the faceplate 34 from the door leaf 3 and engages in the course of its movement into the closed position of the associated fixed frame-side bolt abutment . With the manufacture of this rear handle is a due to the wedge shape of the bolt 29 suit of the door leaf 3 on its fixed frame. As soon as the bolt 29 has reached its closed position, the drive motor 4 is switched off in a load-controlled manner in a known manner. An automatic pivoting back of the bolt 29 into the open position is prevented by the self-locking design of the gear connection of the ring gear segment 28 and the gear spindle 11 . The now existing conditions are shown in Fig. 3 Darge. As can be seen from Fig. 3, the leg spring 38 is now supported with its upper leg 36 from above on the support pin 35 of the ring gear segment 28 and with its un term leg 37 from below on the support pin 39 of the rocker switch 40 under tension. Accordingly, the switching rocker 40 strives to pivot starting from its position in FIG. 3 in a clockwise direction. From such a swivel movement, the rocker switch 40 is prevented by the pawl 49 of the locking device 50 , which the locking end 48 on the upper. Lever arm 47 of the rocker switch 40 engages behind.

To transfer the bolt 29 from the closed to the open position, the locking device 50 is first under Lö sen the positive connection of the pawl 49 and the obe ren lever arm 47 of the rocker switch 40 to switch to the unlocked state. In the case of the locking device 1 according to FIGS. 1 to 4, there are two possibilities.

On the one hand, the electromagnet 53 , which was deenergized during the entire locking process in the interest of low energy consumption and to reduce the risk of system failures, can be switched live. This can be done, for example, by means of a microswitch in the main lock of the door leaf 3 . This microswitch is switched by unlocking the main lock and then ensures that a voltage is applied to the electromagnet 53 . The electromagnet 53 consequently pulls the pawl 49 , the latching end 48 of the upper lever arm 47 of the rocker switch 40 is released and the rocker switch 40 can pivot clockwise under the action of the leg spring 38, starting from its position according to FIG. 3.

In a corresponding manner, the locking device 50 can be transferred manually into the unlocked state with the aid of the drive rod 54 . For example, a separate cylinder lock acting as a panic lock can be provided near the main lock, the cylinder of which engages with a beard in a toothing of the drive rod 54 . If the cylinder of the panic lock is now rotated in the corresponding direction, the drive rod 54 is thereby shifted downwards based on the conditions according to FIG. 3. The attached to the upper end of the drive rod 54 switching cam 56 runs on the switching spring 52 of the locking device 50 and pivots the pawl 49 in a counterclockwise direction into a position in which the pawl 49 the locking end 48 on the upper lever arm 47 of the rocker switch 40 releases ( Fig. 4). The rocker switch 40 can now also pivot clockwise under the action of the leg spring 38, starting from its position according to FIG. 3.

In the course of the pivoting movement of the rocker switch 40 in the clockwise direction, the projection 43 on the lower lever arm 42 of the rocker switch 40 releases the gear spindle 11 in its axial direction 12 . This operating state of the rocker switch 40 is shown in FIG. 4.

The gear spindle 11 can now by the prestressed screw benfeder 20 on the profile shaft 6 suddenly ge down. The intermeshing teeth of the gear spindle 11 and the ring gear segment 28 of the latter and with this also the bolt 29 abruptly pivoted clockwise from the rotary position shown in FIG. 4 into the interior of the lock housing 2 . The gear spindle 11 is at the end of its axial displacement movement on the rubber buffer 18 acting as an end position damper. The bolt 29 assumes its open position. Overall, the starting conditions shown in FIG. 1 again result.

A INTERLOCKS partial shown in FIGS. 5 and 6 averaging device 101 differs from the previously beschrie surrounded type according to FIGS. 1 to 4 essentially by the constructional measures for the manual conversion of a Ver lock-out device 150 in the unlocked state.

Referring to FIGS. 5 and 6 for this purpose instead of the drive rod to before described solution included decentralized panic provided near the electromagnet 53 157. The panic lock 157 has a cylinder 158 with a beard 159 protruding therefrom in the radial direction. The beard 159 is assigned a switching spring 152 connected to the pawl 49 .

If the locking device 150 is now switched manually to the unlocking state, ie the latching end 48 is released on the upper lever arm 47 of the rocker switch 40 , the cylinder 158 is turned clockwise by means of a key, starting from its position illustrated in solid lines in FIG. 5 rotate. The beard 159 on the cylinder 158 runs onto the switching spring 152 and pivots the pawl 49 counterclockwise starting from its position according to FIG. 5. The rocker switch 40 is then released, and there are the conditions shown in Fig. 6, which correspond to the conditions shown in FIG. 4.

Both in the case of the locking device 1 according to FIGS. 1 to 4 and in the case of the locking device 101 according to FIGS. 5 and 6, the helical spring 20 can be mounted in a receptacle which is adjustable in the axial direction of the threaded spindle 11 . By adjusting the receptacle, the prestressing of the helical spring 20 which results when the bolt 29 is in the closed position can be varied. In this way, the energy that can be stored in the coil spring 20 can be matched to the opening forces to be applied in each case. A very rapid movement of the bolt 29 in the open position can be guaranteed in this way also for the case that 3 large opening forces have to be applied, for example as a result of strong distortion of the door leaf.
