DETAILED DESCRIPTION
[0054] The illustrations of FIGS. 1a and 1b show a perspective side view of a modular locking system 10 with different release modules 4 which can be optionally inserted in the locking system 10.
[0055] The locking system 10 essentially comprises a dish 1 and an actuating lever 2, which can be pivoted in relation to the dish 1 and, in the illustration of FIG. 1a, is illustrated in a pivoted-out position. The locking system 10 is arranged on the front side 101 of a door 100, but extends part of the way through this door 100, as can be seen in the illustration of FIG. 1b. The door 100 has two rectangular openings, wherein part of the dish 1 and also an actuating spindle 6 extend through the upper opening, as can also be seen in the sectional view of FIG. 7a. As will be described in yet more detail in respect of the rest of the figures, the actuating spindle 6 is connected to a locking device 8, which is arranged on the other side 102 of the door 100. The lower opening of the door 100, which can be seen in FIG. 1a, serves to hold one of the plurality of release modules 4. Depending on which release module 4 is to be used for the purpose of unlocking the door 100, this release module can be inserted below the dish 1 and can then extend the dish 1 in the downward direction.
[0056] As can be seen in addition in FIGS. 1a and 1b, a cover 5 is additionally provided, this cover concealing the lower opening in the door 100 from the direction of the second side 102 of the door 100, and therefore the release module 4 can be inserted into the door from the front and then covered by the cover 5. Fastening means 7 designed in the form of screws are provided for the purpose of connecting the release module 4 to the cover 5. Once a release module 4 has been selected and inserted in the opening in the door 100, the corresponding release module 4 can be connected to the cover 5 in a disengageable manner via the fastening means 7. In order for the release module 4 to be changed over for another release module 4, it is then necessary, in reverse order, for the fastening means 7 first of all to be disengaged, for the actuating lever 2 to be pivoted out of the dish 1 and for the release module 4 then to be pulled out of the cover 5, or out of the lower opening in the door 100, in the forward direction.
[0057] As can be seen in the illustration of FIG. 2, the actuating lever 2 is held in a pivoted-in position in the dish 1. For this purpose, the dish 1 has a dish holder 1.1, as can be seen, for example, in FIG. 4 or also in FIG. 1 a. When the actuating lever 2, as shown in FIG. 2, is held in the dish 1 in a form-fitting manner, the actuating lever 2 cannot be moved and therefore the door 100 cannot be unlocked. In order for the actuating lever 2 to be pivoted about the actuating axis B according to the illustration in FIG. 1, it is necessary first of all for the actuating lever to be pivoted out of the holding contour 1.1 about the pivot axis S. This is because, as will be described in yet more detail hereinbelow with reference to FIGS. 7 and 8, the actuating lever 2, in the pivoted-in position, is arrested in the dish 1, or in the holding contour 1.1 of the dish 1, by a securing device 3. However, this arresting action can be disengaged again via the release module 4, in which case the actuating lever 2 can then be pivoted out of the dish 1 and pivoted about the actuating axis B for the purpose of actuating the locking device 8. The securing device 3 is connected to the dish 1 and is arranged essentially on the side 102 of the door 100. Although the securing device 3 is obscured from view by the cover 5 in FIGS. 1b and 6a, 6b, it can be seen in the sectional views of FIGS. 7 and 8.
[0058] As can be seen with reference to the illustration of FIG. 3, the actuating lever 2 essentially comprises two elements, namely an actuating portion 2.2, which at one end is connected to the actuating spindle 6, and a lock-cylinder cover 2.1, which is connected to the actuating portion 2.2 in a pivotable manner. In the pivoted-in position, the lock-cylinder cover 2.1 covers over a locking cylinder 4.3 of the release module 4, and therefore, for unlocking purposes, it is necessary first of all for the lock-cylinder cover 2.1 to be swung up, as shown in the illustration of FIG. 3. When the lock-cylinder cover 2.1 has been swung up, the lock cylinder 4.3 is visible and can be rotated for example by means of a key, as is also known from normal house-door locks.
[0059] In the case of the design according to FIG. 4, two different release modules 4 are arranged below the dish 1. Although the two release modules 4 have a similar lock cylinder 4.3, a different key is nevertheless required in each case for unlocking purposes. This stems from the fact that the door 100 is to be opened by two different people, or by two different groups of people, but not everybody is to have the same key. The two release modules 4 are therefore interconnected with the securing device 3 such that all that is required is for just one of the two release modules 4, or the corresponding lock cylinder 4.3, to be rotated in order for it to be possible for the actuating lever 2 to be pivoted out of the dish 1.
[0060] As can also be seen in the illustration of FIG. 3, it is not just the dish 1 which has a holding contour 1.1; rather, the release module 4 also has a corresponding holding contour 4.2, which ensures that, in the pivoted-in position, the actuating lever 2 or the lock-cylinder cover 2.1 terminate flush not just with the dish 1, but also flush with the release module 4. Nevertheless, at one end, the actuating lever 2 however has a handling portion 2.4, which projects downward beyond the lowermost release module 4. This handling portion 2.4 therefore allows one hand to be used to grip behind the lock-cylinder cover 2.1 and then to swing the latter up in the forward direction, in which case the lock cylinder 4.3 is accessible.
[0061] The design of a release module 4 is now to be explained in more detail hereinbelow with reference to FIGS. 5a and 5b. A further design of the release module will also be described in yet more detail hereinbelow with reference to FIGS. 9a and 9b. The release module 4 illustrated in the illustrations of FIGS. 5a and 5b corresponds to the central release module 4 which is illustrated in FIGS. 1a and 1b. Although the further release modules 4 have possibly different lock cylinders 4.3—it can be seen, for example, in FIG. 1a that the two right-hand release modules 4 can be rotated via a tool rather than via a key—the basic construction of the release modules 4 is nevertheless identical. For this purpose, it is only the central release module 4 of FIGS. 1a and b which will be described in more detail hereinbelow, by way of example, with reference to FIGS. 5a and 5b.
[0062] As can be seen first of all, the release module 4 has, on its front side, two profiles 4.1 which project in relation to the holding contour 4.2. These profiles 4.1 ensure that the actuating lever 2 cannot be rotated about the actuating axis B; rather, it has to be pivoted first of all in the forward direction, about the pivot axis S, out of the holding contour 4.2 and also out of the holding contour 1.1 of the dish 1.
[0063] In order to retain the lock-cylinder cover 2.1 in the holding contour 4.2, the release module 4 has a retaining element 4.4, designed in the form of a permanent magnet, in the lower part of the holding contour 4.2. When the lock-cylinder cover 2.1 is located in the holding contour 4.2 of the release module 4, according to the illustration in FIG. 2, this retaining element 4.4 therefore ensures that the lock-cylinder cover 2.1 is not accidentally pivoted upward in relation to the actuating portion 2.2. In order for the lock cylinder 4.3 to be exposed, it is then necessary for the retaining force of the retaining element 4.4 to be overcome when the lock-cylinder cover 2.1 is being pivoted up.
[0064] As can also be seen, the lock cylinder 4.3, which can be rotated about the unlocking axis E via a key, is connected to a release finger 4.5, which is arranged so as to project radially in relation to the unlocking axis E. When the lock cylinder 4.3 rotates, the unlocking finger 4.5 also moves correspondingly and can then release the securing device 3. It is also the case that FIG. 5b illustrates two fastening holders 4.8, which are designed in the form of threaded bores, in which case the fastening means 7 can be screwed into the two fastening holders 4.8, through the cover 5, from the outside and can thus connect the release module 4 to the cover 5.
[0065] It can also be seen that the release module 4 has a bearing region 4.6, which extends over three sides of the release module 4. When the release module 4 is inserted into the opening in the door 100, for example according to the illustration in FIG. 1a, this bearing region 4.6, which is designed in the manner of a collar, bears on the outer side 101 of the door 100 and the rest of the release module 4 extends through the door 100. Three sides of the release module 4 therefore butt against the door 100.
[0066] As can further be seen in the illustration of FIG. 4, in the case of a plurality of release modules 4 arranged one below the other, these release modules can have somewhat different outer contours and therefore also different bearing regions 4.6. For example, only two sides of the upper release module 4 bear against the outer side 101 of the door 100, but, correspondingly, also a lower side of the lower release module 4, and therefore three sides of this release module, bear on the door 100. The upper release module 4 is designed in the form of an intermediate piece and the lower release module 4 is designed in the form of an endpiece.
[0067] As can be seen with reference to FIGS. 6a and 6b, the actuating spindle 6 is connected to a locking device 8 on the inner side 102 of the door 100. In a locked position, the locking device 8 can secure the door 100 in relation to a door frame, in which case the door 100 cannot be opened. In an unlocking position, the locking device 8 can allow corresponding movement of the door 100, and therefore the latter can be opened. As can also be seen, the locking device 8 can be designed in different ways. In the illustration of FIG. 6a, it is designed, for example, in the form of a lock case 8.2 with two locking rods. In the design according to FIG. 6b, the locking device 8 is designed in the form of a casement lock 8.1, which is connected to the actuating lever 2 in a rotatable manner. To this extent, the modular locking system 10 provides for a modular changeover not just of the release modules 4, but also of the locking device 8, depending on the requirements which have to be met by the locking system 10.
[0068] The more precise internal design of the locking system 10 is now to be described hereinbelow with reference to FIGS. 7a, 7b and 8a, 8b.
[0069] The illustration of FIG. 7a shows a lateral sectional view of the locking system 10. The actuating lever 2 here has been pivoted, about the pivot axis S, out of the holding contour 1.1 of the dish 1 and also out of the holding contour 4.2 of the release module 4 and, in this position, can be rotated about the actuating axis B in order to lock or to unlock the door. As can also be seen, the actuating lever 2, or the actuating portion 2.2, has a hook portion 2.3, which projects inward, that is to say in the direction of the dish 1. When the actuating lever 2 is pivoted about the pivot axis S and is pushed into the holding contour 1.1 of the dish 1, the hook portion 2.3 interacts with the securing device 3 such that the latter arrests the actuating lever 2 in the dish 1. This position is illustrated in FIG. 7b.
[0070] The securing device 3 has a securing catch 3.1, which has a hook-like end 3.5 at one end. In the pivoted-in position shown in FIG. 7b, this hook end 3.5 is in engagement with the hook portion 2.3 of the actuating lever 2, and therefore the actuating lever 2 can no longer be pivoted, about the pivot axis S, out of the dish 1. In order for the door 100 to be unlocked, the actuating lever 2 first of all has to be pivoted out of the dish 1 again and transferred into the position illustrated in FIG. 7a. For this purpose, the hook end 3.5 of the securing device 3 and also the hook portion 2.3 of the actuating lever 2 first of all have to be disengaged again.
[0071] The securing catch 3.1 is guided in a guide 3.3 and can therefore be moved linearly. The securing catch 3.1, and therefore also the hook end 3.5, is prestressed into the arresting position via a spring element 3.2, which is designed in the form of a compression spring. If the locking cylinder 4.3 of the release module 4 is then rotated about the unlocking axis E, the release finger 4.5 comes into contact with the securing catch 3.1 and moves the latter within the guide 3.3 counter to the spring force of the spring element 3.2. When the lock cylinder 4.3 has been rotated far enough, the securing catch 3.1 has been displaced to such an extent that the hook end 3.5 and the hook portion 2.3 are no longer in engagement and the actuating lever 2 can then be pivoted, about the pivot axis S, out of the dish 1. The different release modules 4 all have a similar release finger 4.5, which, when the lock cylinder 4.3 moves, moves the securing catch 3.1 such that the arresting action of the actuating lever 2 is disengaged. To this extent, there is no need for the securing device 3 to be altered or adapted when the release module 4 is changed over.
[0072] In the case of the exemplary embodiment which is shown in the illustration of FIGS. 8a and 8b, the locking system 10 functions basically in the same way as has already been described above in respect of FIGS. 7a and 7b. It is only the design of the securing device 3 which is different. This is because the securing device, rather than having a linearly movable securing catch 3.1, has a securing catch 3.1 which is mounted such that it can be pivoted about a point of rotation 3.4. In the locked position, which is illustrated in FIG. 8b, the hook end 3.5 of the securing catch 3.1 engages in the hook portion 2.3 of the actuating portion 2.2 from below and thus retains the actuating lever 2 in an arrested state on or in the holding contour 1.1 of the dish 1. It is also the case that the rotatable securing catch 3.1 is prestressed into the arresting position via a spring element 3.2, and therefore, when the lock cylinder 4.3 rotates, the securing catch is then pivoted about the point of rotation 3.4 by the unlocking finger 4.5, in which case the hook end 3.5 and the hook portion 2.3 disengage. Also clear to see in this sectional view is the downwardly projecting handling portion 2.4, which has to be swung up prior to the lock cylinder 4.3 being rotated, as has already been described above in respect of FIGS. 2 and 3.
[0073] In both designs, the actuating portion 2.2 has its lower end covering over an upper edge of the release module 4. Accordingly, the release module 4 can be pulled out of the cover 5 or of the door 100 only when, on the one hand, the fastening means 7 have been disengaged and, in addition, the actuating lever 2, or the actuating portion 2.2, has also been pivoted out of the dish 1. To this extent, it is not possible for the release module 4 to be removed without the lock cylinder 4.3 having been rotated into the release position by means of the appropriate key. Even if a person has, for example, access to the fastening means 7, it is necessary, for the purpose of removing the release module 4, for this person also to have the correct key.
[0074] The release module 4 illustrated in FIGS. 9a and 9b essentially corresponds to the release module 4 which has already been described in respect of FIGS. 5a and 5b or also to those which are illustrated in FIGS. 1a and 1b. In addition, however, the release module 4 of FIGS. 9a and 9b has, at the upper end, two guide pins 4.9, via which the release module 4 can engage in the dish 1. The dish 1 has a corresponding holder, into which the guide pins 4.9 move as they are fitted into the dish. It is therefore also possible for the release modules 4 to be guided in the dish 1 via the guide pins 4.9.
[0075] It is also the case that the cover 5 is shown in an enlarged view in the perspective illustration of FIGS. 10a and 10b. On their inner side, the side walls of the cover 5 have guiding crosspieces 5.1, on which the release modules 4 can be supported as they are pushed into the cover 5. As can be seen, four guiding crosspieces 5.1 are provided here, in each case two guiding crosspieces 5.1 being arranged on opposite sides of the cover 5.
