[0057] In the illustration of FIG. 1, a main body 3 with an actuating element 5 is shown in a top view. The main body 3 is arranged on the outer side of a closure element which is configured as a door but which is not illustrated in the figures. The door can be secured in relation to the door frame in the closed position via the locking system 10, and therefore the door can no longer be opened. This will also be explained in more detail below with reference to FIGS. 4a to 4c.

[0058] In order to unlock the door or the locking system 10, the actuating element 5 has to be rotated about an actuating axis B. However, in the positions of the actuating element 5 that are shown in FIGS. 2 and 3a to 3d, the latter is located in the main body 3 in such a manner that a rotational movement of the actuating element 5 is not possible. In order to rotate the actuating element 5, the latter first of all has to be pivoted out of the main body 3, as can be seen in FIGS. 4a to 4d. The actuating element 3 substantially consists of two parts, namely of the grip region 5.2, which can be seen in FIGS. 1 to 4, and of an actuating shaft 5.1, which extends through the main body 3. The actuating shaft 5.1 is mounted rotatably in the main body and is connected at one end to the grip region 5.2 via a hinge connection. Owing to the pivotable connection between the grip region 5.2 and the actuating shaft 5.1, the grip region 5.2 can be pivoted in relation to the actuating shaft 5.1 and therefore also in relation to the main body 3, as can be seen in FIGS. 4a to 4c.

[0059] So that the grip region 5.2 can be pivoted out of the main body 3, the main body 3 has a recessed grip 3.2. The grip region 5.2 protrudes for a small distance above the recessed grip 3.2, and therefore it is possible to grip with one hand in the recessed grip 3.2 and behind the grip region 5.2 in order to pivot the grip region 5.2 out of the main body. In the pivoted-out position shown in FIG. 4b, the actuating element 5 can then be rotated since the main body 3 no longer grips around the grip region 5.2 and to this extent also no longer prevents the latter from a corresponding movement. Since, in order to rotate the actuating element 5, the latter has to be pivoted out of the main body 3, it is possible, by preventing this pivoting-out, also to prevent the door from being able to be correspondingly unlocked. In order to secure the grip region 5.2 in this respect in the main body 3, a securing device 7 in the manner of a lock is provided. Therefore, before the actuating element 5 can be pivoted out and rotated, the securing device 7 first of all has to be unlocked.

[0060] As can be seen in FIGS. 3a to 3d, the securing device 7 can comprise various types of lock. For example, FIGS. 3b and 3c show various plug-in cylinders which can be unlocked by keys, and FIG. 3a shows a securing device 7 which can be unlocked by a tool. In addition, a protective cap may also be provided, as can be seen in FIG. 3d and with which it is possible to prevent dirt from penetrating the closing cylinders of the securing devices 7.

[0061] Furthermore, the locking system 10 permits a push-to-lock function. For this purpose, the main body 3 has a spring-loaded catch hook 3.3 which, in the pivoted-in position of the grip region 5.2, engages in the latter. When the grip region 5.2 is pivoted in, the catch hook 3.3 automatically yields counter to the spring force and then, because of the spring force, also automatically engages again in the grip region 5.2 or in the securing device 7. A renewed pivoting-out of the grip region 5.2 is then possible only when the securing device 7 is unlocked. Since the catch hook 3.3 automatically yields when the grip region 5.2 is pivoted in, the grip region 5.2 can always be pivoted into the main body 3 independently of the position of the securing device 7, and is then first of all locked once.

[0062] The catch hook 3.3 is mounted in the main body 3 from the front side or outer side thereof, and therefore the main body 3 does not require any corresponding installation apertures. This can also be seen, for example, with reference to FIGS. 5a to 5c. This is because the rear side or inner side of the main body 3 does not have any apertures or openings, at least in the region in which the pivoted-in grip region 5.2 is arranged, but rather a closed rear side, and therefore to this extent no seals are required either.

[0063] As can furthermore be seen in FIGS. 4a to 4b, the main body 3 has an indicator surface 3.1 which is visible only when the grip region 5.2 has been pivoted out of the main body 3. This indicator surface 3.1 is colored in in a signal color and therefore is also readily visible from far away. In this respect, it can then be seen at first glance whether the grip region 5.2 has or has not been pivoted out and whether the door is reliably locked.

[0064] In order to lock a door via the locking system 10, the rear side of the main body 3 is provided with a locking module 1 with a locking element 2 which is rotatable to and fro between a locking position and an unlocking position via the actuating element 5. The locking position is shown in FIG. 4a. In said locking position, the locking element 2 of the locking module can reach into or behind the door frame and can thereby secure the door in relation to the door frame. In order to open the door, the locking element 2 then firstly has to be transferred into the unlocking position illustrated in FIG. 4c. For a corresponding actuation, the locking module 1 is coupled to the actuating element 5 such that, by means of the rotational movement of the actuating element 5 or of the grip region 5.2, the locking module 1 can be transferred into the locking position or into the unlocking position.

[0065] As can be seen in FIG. 4c, the locking element 2 in this unlocking position is rotated by approx. 90 degrees in relation to the locking position, and therefore the locking element 2 in this position no longer engages in or behind the door frame and the door can then to this extent be opened. In order to connect the locking module 1 to the actuating element 5, an interface 6 which, upon actuation, rotates together with the actuating element 5, is arranged at the lower end of the actuating shaft 5.1. The locking module 1 can be connected to the actuating element 5 for rotation therewith via said interface 6, and therefore, in the event of an actuation, the locking element also rotates about the actuating axis B. For the connection, use can be made of a connecting element 8 in the form of a screw, via which the locking module 1 can then be releasably connected to the actuating element 5, as is also apparent, for example, in FIG. 5a which shows the lower side of the locking system 10.

[0066] Furthermore, in addition to the interface 6 which is rotatable together with the actuating element 5, yet another interface 4 is also provided which serves to connect the locking module 1 to the main body 3. However, in contrast to the interface 6, the interface 4 is fixed. In the case of the locking module 1 shown in FIGS. 5a to 5d, this interface 4, however, is not populated since this type of locking module requires just one connection to the actuating element 5. Other types of locking module, such as the latch-lock module 1.2 illustrated in FIG. 6, require, however, not only a connection to the actuating element 5, but furthermore yet another interface, which is fixed nonrotatably, for connection to the main body 3. The locking system 10 can therefore be used both with locking modules 1 which require just the interface 6, and with those which, in addition to the interface 6, also require the interface 4. First of all, differently configured locking modules 1 which can be assigned to the first type of locking module and which are all configured in the manner of a casement-lock module 1.1, will now be described below with reference to FIGS. 5a to 5d before, subsequently, the second type of locking module that is illustrated in FIGS. 6 and 7a, 7b will then be discussed in more detail.

[0067] The casement-lock module 1.1 according to FIG. 5a has a locking element 2 which is configured as a roller tongue and is directly connected to the interface 6 and/or to the actuating element 5. When the actuating element 5 is rotated, the locking element 2 correspondingly also rotates to and fro, as has already been described above with regard to FIGS. 4a to 4c. The roller tongue can freely rotate about its longitudinal axis, which facilitates shutting of the door since the roller can run on or at the door frame. In addition, a certain degree of compression of the door seal can also be achieved via the roller tongue.

[0068] In the configuration which is illustrated in FIG. 5b, the roller tongue is connected to the actuating element 5 via a guide 1.11. The roller tongue can therefore be moved in the direction of the actuating axis and therefore perpendicularly to the door, as a result of which the roller tongue can be adapted to different geometrical dimensions of the door or the door frame. The locking module of FIG. 5c likewise has the guide which is illustrated in FIG. 5b. However, the locking element 2 in this locking module 1 is configured as a hook tongue.

[0069] The locking module 1 shown in FIG. 5d is likewise a casement-lock module 1.1, but the actual casement-lock tongues are not also illustrated. Instead, a rod drive 1.12 is shown via which the actuating element 5 can also be connected to a plurality of casement-lock tongues. For this purpose, the rod drive 1.12 has two rods 1.13 which extend in different directions and via which a respective casement-lock tongue can be driven. To this extent, this locking module 1 provides multi-point locking for the door. The rod drive 1.12 furthermore has a coupling element 1.14 which is connected via the interface 6 to the actuating element 5 and which ensures that the rotational movement of the actuating element 5 is converted into a substantially linear movement of the two rods 1.13.

[0070] FIG. 6 illustrates a different type of locking module 1, namely a latch-lock module 1.2. In contrast to the casement-lock module 1.1, the latch-lock module 1.2 not only requires a rotatable interface 6 for connection to the actuating element, but in addition also a fixed interface 4 for connection to the main body 3. The corresponding interface 4 has a total of four individual points of connection 4.1 which are each arranged in pairs next to the actuating shaft 5.2 on the lower side of the main body 3. Unlike the casement-lock module 1.1, the latch-lock module 1.2 is configured in two parts and consists essentially of a frame 1.21 and a driver 1.25. The driver 1.25 functions basically in a similar manner to the locking element 2 of the casement-lock modules. This is because it is likewise connected to the rotatable interface 6 and can thus be rotated to and fro via the actuating element 5. The driver 1.25 is arranged here on a union sleeve which is connected in the upper region to the actuating shaft 5.1 and which is adjoined at the lower end by the driver 1.25 perpendicularly to the actuating axis B, as can be seen in FIG. 6.

[0071] The second part of the latch-lock module 1.2 is configured as a frame 1.21 and connected to the main body 3 via the fixed interface 4. The frame 1.21 has two frame plates 1.22 which each consist of two frame limbs, namely a fastening limb and a bearing limb, which are arranged at 90 degrees to each other. The fastening limbs lie directly one on the other and are connected to the four points of connection 4.1 of the interfaces 4 via screws. The bearing limbs, which are arranged perpendicularly to the fastening limbs, are at a certain distance from one another and a locking element 2 configured as a rotary latch is arranged rotatably between them. The rotary latch together with the two frame limbs 1.22 or the two bearing limbs can accommodate a bolt 1.26 in a form-fitting manner, and therefore the bolt 1.26 then at least can no longer be moved in a translational manner. In this position, the door then can no longer be moved in relation to the door frame either.

[0072] To accommodate and secure the bolt, the rotary latch has a U-shaped receiving region and the bearing limbs have a locking groove 1.12. When the door is closed, the bolt 1.26 enters the locking groove 1.12 and at the same time also the rotary latch. The rotary latch is pivoted in the process and rotated into the locked position, as is apparent in FIGS. 7a and 7b. The locking element 2 is pretensioned via a spring element into the unlocking position, and therefore, when the door is closed, the bolt 1.26 is moved counter to the force of the spring and said bolt presses the locking element 2 into the locking position. In the locking position, the rotary latch is firmly held by an arresting pin 1.24 and prevented from rotating back into the unlocking position. The door is therefore automatically locked upon closing when the locking element has reached the locking position.

[0073] To open the door, the rotary latch has to be rotated back into the unlocking position. Since the rotary latch is pretensioned into the unlocking position, this takes place automatically if the arresting pin 1.24 no longer fixes the rotary latch in the locking position. The rotary latch then springs back into the unlocking position and the door can be opened again.

[0074] In order to correspondingly move the arresting pin 1.24, the actuating element 5 has to be rotated about the actuating axis B, precisely as has already been described above with regard to the casement-lock module 1.1. During this movement, the driver 1.25 comes into contact with the arresting pin 1.24 and correspondingly carries the latter along with it. Owing to the corresponding movement of the arresting pin 1.24, the rotary latch is then released and snaps up because of the spring pretensioning. A renewed movement of the rotary latch into the locking position is not possible by the driver 1.25 or by rotation of the actuating element 5. Unlike in the case of the casement-lock module 1.1, in the case of the latch-lock module 1.2 the locking element 2 has to be transferred into the locking position by means of the closing movement of the door or by means of the corresponding movement of the bolt 1.26. By rotation of the actuating element 5, the locking element 2 therefore can just be unlocked, but not locked.
