    The invention relates to a multi-point lock, in particular an electromechanical multi-point lock with a mechanical Notbetätigungsmöglichkeit a lock cylinder comprising a arranged in a housing push rod, at least one cam having a cam, wherein a pin of the push rod is guided in the control cam and the bolt is actuated via this pin , an operable by a nut with attached pusher and alternatively by the lock cylinder latch, and optionally further actuated by the push rod locking elements.
    Known mechanical as well as electromechanical locks often have a complex mechanism. Most are two-speed or maximum one-speed locks, in which the user must turn the key two or once completely around to lock or unlock the lock.
    On the one hand, the mechanism serves to translate the rotary movement of the key into a stroke that is as large as possible in order to be able to displace bolts and other locking elements far out, and on the other hand, the mechanism serves to minimize the torque on the key, in order to maximize user-friendly operation enable. In particular, in electromechanical locks, the provision of a conventional mechanism for the emergency operation in addition to the electric drive is very complex and therefore costly. In addition, it comes in normal operation to a reduced efficiency of the electric drive, since with each closing the entire lock mechanism must be moved passively. Especially with battery-operated locks this has a negative effect on the runtime.
    Another problem arises from the fact that in conventional locks when opening on the lock cylinder first, the locks must be solved and only at the end of the rotation of the case is relocated into the castle, in which case on short distances a particularly high torque occurs, which has a detrimental effect on the unlocking process. 2/15 2
    It is therefore desirable to provide a lock which is simple in construction and operable via a conventional lock cylinder and, among other things, is particularly effective for the use of an electromechanical drive, the possibility of an emergency operation in case of failure of the electrical system is made possible. Furthermore, it is desired that even a very small revolution of the lock cylinder of a maximum of half a turn is sufficient to move the lock from the locked position to an unlocked position, as this allows a pleasant and easy handling by the user. At the same time it should be possible that the displacement of the trap during the unlocking operation via the lock cylinder with a reduced torque, in order to increase the user-friendliness of the lock on.
    This object is achieved in that the locking lug of the lock cylinder actuates a cylinder cam which can be brought into operative connection by means of a projection with a blocking segment and the unlocking subsequently with a first change lever, wherein the Sperrsegement is in operative connection with the push rod, and wherein the first change lever is operatively connected to a second change lever which is engageable with the case retracting lever and that the path of the rotational movement of the lock cylinder from the locked position to the open position corresponds to a maximum of one-half turn with the latch retracted over the first and second change levers , wherein at the Entsperrvorgang the displacement of the bolt and the case takes place at least partially simultaneously. Due to the low rotation angle, a relatively high torque is generated by mechanical actuation via the key. Surprisingly, however, it has been found that this torque is sufficiently low to allow a user-friendly operation with little wear. In particular, in the case of an electromechanical lock, actuation is normally effected by an electric motor, in which a complex gear in the lock would lower the efficiency of the electric motor, since this would have to passively pass through the motor during each closing operation. Since the mechanical actuation of an electromechanical lock on the 3/15 3
    Key only in exceptional cases, for example in case of power failure occurs, an increased torque for the application of the emergency operation can be accepted in any case. The advantages of the simple lock mechanism by providing fewer parts, as well as the better efficiency when controlled by the electric motor bring in the whole a significant advantage for this lock structure. Due to the two change levers for shifting the trap, this can already be displaced simultaneously with the latch and not as usual until then. This has the advantage that from the point of rotational movement, at which the cylinder cam interacts with the first change lever, until the end of the rotational movement a much longer path of movement is available than before, whereby the otherwise occurring high torque is minimized at the end of the unlocking.
    It is a further feature of the invention that the first change lever has a projection which cooperates with the cylinder cam during the unlocking operation, and that the first change lever is displaceable substantially parallel to the push rod, wherein between the first and second change lever an articulated connection is provided. The first change lever can be accommodated as space-saving. The second is rotatably arranged on one side about the nut, wherein the pivot point substantially corresponds to the axis of the nut. At the other end, the second change lever is pivotally connected to the first change lever, whereby the longitudinal displacement of the first change lever is translated into a rotational movement of the second change lever.
    According to a further feature of the invention, it is provided that the blocking segment has a cantilever arm with a slotted guide, in which a projection of the push rod is guided. By this embodiment, it is possible in a simple and efficient manner to allow the transmission of power from the locking segment on the push rod. Alternatively, the slotted guide can be arranged on the push rod and the projection on the boom. 4/15 4
    Another feature of the invention is that the slotted guide on the cantilever arm arcuate, in particular circular arc-shaped, wherein the arc is convexly curved in the locked position upwards. As an alternative, the bow can also be curved downwards. Due to the design of the gate, the force is optimally introduced in the thrust direction of the push rod during the closing process. When opening only a small resistance of the spring-loaded push rod brake must be overcome, whereby in this area the backdrop can be made somewhat steeper, resulting in the circular arc shape.
    It is a further feature of the invention that for alternative actuation of the case via the push rod, a sliding element fixed to the push rod cooperates with the rotatably mounted latch retracting lever via a rotatably mounted latch lever in order to displace the push rod, for example by an electric motor or via the door handle and the associated nut to retract the trap into the housing against the force of a spring. This arrangement proves to be favorable in order to translate the only small thrust stroke of the push rod in the end to the longer compared to the way the retreat of the trap.
    The invention will now be explained in more detail with reference to the accompanying figures. It shows
    1 shows a schematic section through an embodiment of an inventive multi-lock lock in the locked position,
    FIG. 2 shows a schematic section through the lock from FIG. 1 in an intermediate position during the unlocking process, FIG.
    3 shows a schematic section through the lock of FIG. 1 in the unlocked position with retracted latch and FIG. 4 shows a schematic section through the lock of FIG. 1 with the latched out latch.
    In a multi-lock lock according to FIGS. 1 to 4, a latch 12 which can be actuated via a nut 8 is arranged in a housing 1. Furthermore, in the housing 1 for controlling the lock via an electric drive (not shown) or 5/15 5 via a lock cylinder, a push rod 6, which by a locking segment 2 with a boom 3 via a slotted guide 4, in which a projection 5 of the push rod 6 engages, is operable. A pin 18 of the push rod 6 engages in a control cam 17 of a bolt 16 to cause the extension or retraction of the bolt 16 during movement of the push rod 6. Furthermore, located on the push rod 6, a sliding element 9, which causes the retraction of the case 12, alternatively to the control via the nut 8, upon movement of the push rod in the corresponding position in cooperation with a latch lever 10 and a latch retracting lever 11. Upon actuation by means of the door handle via the nut 8, the arm 8 extending downward from the nut 8 rotates upwards and presses from below against the sliding element 9 arranged on the push rod 6. The push rod 6 is pushed upwards and the catch is as described above withdrawn. Furthermore, a first change lever 19, which runs parallel to the push rod 6, is located in the housing 1. The first change lever 19 is in articulated connection with a second change lever 20 which acts with a projection on the case retracting lever 11. At the lower end of the first change lever 19 has a projection 15. When turning the lock cylinder acts a cylinder cam 13 with an attack surface 14 of the locking segment 2 and subsequently also with the projection 15 of the first change lever 19 together.
    In Fig. 1, the locked position is shown with ejected latch 16. The push rod was pulled to lock by the boom 3 on the guided in the slide guide 4 projection 5 of the push rod 6 down. In this case, the pin 18 moved along the control cam 17 of the bolt 16 and displaced them to the outside. When unlocking the lock cylinder now the cylinder cam 13 is rotated and first presses against an attack surface 14 of the Sperrsegements 2. This pushes the push rod 6 upwards, whereby the latch 16 is displaced into the lock.
    In Fig. 2, an intermediate position during the unlocking process is shown. After the bolt already a certain way in 6/15 6
    Towards the direction of the unlocked position, as the lock cylinder continues to rotate, the cylinder cam 13 strikes a projection 15 of the first change lever 19 and also pushes it upward. From this point on the second change lever 20 and in consequence on the case retracting lever 11, the latch 12 is moved into the castle. The unlocking of the bolt 16 and the shifting of the trap 12 is done from this time so simultaneously. As a result, substantially more movement of the cylinder cam 13 is available for the displacement of the latch 12 than in conventional locks, in which the latch 12 is displaced only at the end of the locking operation. The occurring torque peak at the end of the locking process is thus avoided.
    Fig. 3 finally shows the unlocked position of the lock with retracted over the cylinder cam 13 case 12. When unlocking requires less force than when locking, thus the slide guide 4 can be configured on the boom 3 here steeper. Alternatively, the case 12 can also be displaced via the nut 8 or directly via the push rod 6, for example by an electric motor. In this case pushes the push rod 6 with a slider 9 against a latch lever 10, which in turn presses on a latch retracting lever 11 and pulls the case 12 against the force of a spring in the castle. The nut 8 also acts with an arm extending therefrom against the slider 9 to displace the latch 12 in the manner just described.
    Fig. 4 shows the unlocked position of the lock with again ejected case 12. The spring of the case presses on the case retracting lever 11, the second change lever 20 and thus the first change lever 19 and the cylinder cam 13 down. The attack surface 14 of the Sperrsegements 2 comes out of engagement with the cylinder cam 13. The locking segment 2 remains in the unlocked position. A push rod brake 7 keeps the push rod in position.
    The locking and unlocking as well as the actuation of the latch 12 takes place by rotating the cylinder cam 13 by less than 7/15 7 a half to a maximum of half a turn. The control is carried out in an embodiment as an electromechanical lock by an electric motor and only in exceptional cases directly via the lock cylinder. Due to the very simple structure of the castle parts can be saved, which reduces the cost of production. Furthermore, the power transmission through the electric motor is particularly effective, since there are no losses due to the passive co-moving of a complex mechanical transmission.
