DETAILED DESCRIPTION

[0037] FIG. 1 shows a view of a door locking system 1 according to the invention while being mounted to a door 2. FIG. 2 shows a view of the finish-mounted door locking system 1. The door locking system 1 is provided for opening and for locking the door 2 and operatively connected to a lock 3 within the door 2. The door 2 and the lock 3 are not part of the present invention.

[0038] The door locking system 1 according to the invention comprises a first door handle unit 4a and a second door handle unit 4b. The first door handle unit 4a includes a first door handle 5a and a first cover plate 6a and the second door handle unit 4b includes a second door handle 5b and a second cover plate 6b. The two door handle units 4a and 4b are connected to one another through the door 2 by means of a mounting device 7. The mounting device 7 includes a first mounting plate 8a—not visible here—and a second mounting plate 8b, which are fixed to one another via two mounting pins 9. The door handles 5a and 5b is pivotable about a mounting axis 10 and the cover plates 6a and 6b are securely connected to mounting plates 8a and 8b. The cover plates 6a and 6b are pot-shaped and axially and radially receive the mounting plates 8a and 8b so that the mounting device 7 is not visible from the outside. By way of a pin 20 with a polygonal cross-section, the door handles 5a and 5b are non-rotatably connected to one another and additionally operatively connected to the lock 3. The door handles 5a and 5b can be manually adjusted from a locking position into an open position and automatically from the open position into the locking position. In the locking position of the door handles 5a and 5b—as shown here—the lock 3 is closed and in the open position of the door handles 5a and 5b, the lock 3 is open.

[0039] The door locking system 1 is mounted to the door 2 by means of the mounting device 7. To this end, the first mounting plate 8a—not visible here—with the pre-assembled first door handle unit 4a and the mounting plate 8b with the pre-assembled second door handle unit 4b are pushed along the mounting axis 10 and through the door 2 onto one another as shown in FIG. 1. The mounting pins 9 are fixed to the second mounting plate 8b and oriented to the first mounting plate 8a. During the mounting, the two mounting pins 9 are received in the first mounting plate 8a—not visible here—and subsequently fixed radially and axially. After the mounting, the two mounting plates 8a and 8b are oriented coaxially to the mounting axis 10 and fixed to the door 2 on both sides as shown in FIG. 2. Further details regarding the construction and regarding the mounting of the door locking system 1 are explained in more detail by way of FIG. 3 to FIG. 10.

[0040] FIG. 3 shows a view of the second door handle unit 4b and partially of the mounting device 7 with the mounting pins 9. In FIG. 4, a partial sectional view of the first door handle unit 4a and partially of the mounting device 7 with the mounting pins 9 is shown. In FIG. 4, a region A is drawn in which is shown enlarged in FIG. 9.

[0041] Making reference to FIG. 4, the first door handle unit 4a includes the door handle 5a and the cover plate 6a. By means of a first fixing ring the door handle 5a is fixed axially on the first mounting plate 8a and pivotably about the mounting axis 10. In addition, the first door handle unit 4a comprises a first resetting unit 11a which includes a stop plate 12a with two radially oriented stop arms 13 and with two coil springs 14 oriented in the circumferential direction. The construction of the resetting unit 11 is explained in more detail in the following by way of FIG. 5 and FIG. 7.

[0042] The first mounting plate 8a comprises two first openings 15 for the two mounting pins 9. The two first openings 15 are formed in regions by flaps 16, which are pivotably fastened to the mounting plate 8a transversely to the mounting axis 10 into a mounting position—see FIGS. 5 and 6 in this regard—and into a blocking position—see FIG. 7 and FIG. 8 in this regard. In the mounting position, the flaps 16 are freely pivotable so that the mounting pins 9 are slidable in the first openings 15. When the flaps 16 are adjusted into the mounting position, the two mounting plates 8a and 8b can be guided towards one another and apart from one another along the mounting axis 10. Accordingly, the door locking system 1 can be mounted to the door 2 or dismounted from the door 2. In the blocking position, the flaps 16 are pressed onto the mounting pins 9 by means of a blocking unit 17 and the mounting pins 9 are axially and radially fixed in the first openings 15. When the flaps 16 are adjusted into the blocking position, the two mounting plates 8a and 8b cannot be moved along the mounting axis 10. Accordingly, the door locking system 1 cannot be dismounted from the door 2. The blocking unit 17 is formed by two projections 18 on the first cover plate 6a. The construction of the blocking unit 17 and the interaction of the blocking unit 17 with the flaps 16 are explained in more detail in the following by way of FIG. 5 to FIG. 8.

[0043] Making reference to FIG. 3, the second door handle unit 4b comprises the second door handle 5b and the second cover plate 6b. By means of a second fixing ring 19b, the second door handle 5b is axially fixed to the second mounting plate 8 and pivotably about the mounting axis 10. In addition, the second door handle unit 4b comprises a second resetting unit 11b, which includes a second stop plate 12b with two radially oriented stop arms 13 and two coil springs 14 oriented in the circumferential direction. The door handles 5a and 5b, the fixing rings 19a and 19b and the resetting units 11a and 11b are formed identically to one another. In contrast with the first mounting plate 8a, the second mounting plate 8b comprises two second unchangeable openings 26 into which the mounting pins 9 are screwed and thus fixed axially and radially. The second cover plate 6b is additionally formed in one piece on the second mounting plate 8b. In the second door handle 5b, the pin 20 with a polygonal cross-section is received in a form-fitted manner, which following the mounting along the mounting axis 10 engages in the first door handle 5a in a form-fitted manner.

[0044] FIG. 5 now shows a view of the first door handle unit 4a transversely to the mounting axis 10. In FIG. 6, the drawn-in region B from FIG. 5 is shown enlarged. In FIG. 5 and FIG. 6, the first cover plate 6a is located in a mounting position and the flaps 16 of the first openings 15 in the corresponding mounting position. To this end, the first cover plate 6a is pivoted about the mounting axis 10 so that the projections 18 of the blocking unit 17 are not in engagement with the flaps 16. Because of this, the flaps 16 are freely pivotable so that the first openings 15 cannot change their diameter. Thus, when the first cover plate 6a is in the mounting position and the flaps 16 are in the mounting position, the mounting pins 9, during the mounting of the door locking system 1, can be axially introduced into the first openings 15 and during the dismounting of the door locking system 1, axially removed from the first openings 15. Advantageously, the cover plate 6a can be fixable in the mounting position by a detent unit—not shown here.

[0045] FIG. 7 now shows a view of the first door handle unit 4a transversely to the mounting axis 10. In FIG. 8, the drawn-in region C from FIG. 7 is shown enlarged. In FIG. 7 and FIG. 8, the first cover plate 6a is located in a blocking position and the flaps 16 of the first openings 15 in the corresponding blocking position. To this end, the first cover plate 6a is pivoted about the mounting axis 10 so that the projections 18 of the blocking unit 17 are in engagement with the flaps 16. When pivoting the cover plate 6a, the projections 18 are guided on ramps 21 of the flaps 16 until the flaps 16 are pressed against the mounting pins 9—not shown here—with sufficient force. In the first openings 15—here only on the flaps 16—threads 22 are formed which correspond to counter-threads 23 of the mounting pins 9. Thus, when the cover plate 6a is in the blocking position, the flaps 16 are pressed against the mounting pins 9 and the threads 22 are in engagement with the counter-threads 23. Because of this, the mounting pins 9 are axially and radially fixed in the first openings 15 and the dismounting of the door locking system 1 is not possible. Advantageously, the first cover plate 6a can be fixable in the blocking position by the abovementioned detent unit—not shown here.

[0046] In order to prevent over-rotating the cover plate 6a on the first mounting plate 8a, the door handle unit 4a comprises two stop units 29. The respective stop unit 29 each includes the one projection 18 and a further stop projection 27 on the first cover plate 6a and two stop points 28 each on the first mounting plate 8a. In the mounting position of the first cover plate 6a, the respective projections 18 and the respective stop points 28 are in engagement in the circumferential direction and in the blocking position of the first cover plate 6a, the respective stop projections 27 and the respective other stop points 28 are in engagement in the circumferential direction. The blocking position and the mounting position of the first cover plate 6a are thereby predefined. By way of the stop units 29, an over-rotating of the first cover plate 6a during the mounting can be prevented and thereby ensured that the flaps 16 are in fact situated in the blocking position.

[0047] FIG. 9 and FIG. 10 show enlarged views of the region A of the first door handle unit 4a from FIG. 4. Here, the blocking unit 17 on the cover plate 6a is adjusted into the blocking position and the flaps 16 are pressed against the mounting pins 9. As is also shown in FIG. 5 to FIG. 8, the thread 22 is only formed on the flaps 16. Because of this, the mounting pins 9 during the mounting can be introduced into the first openings 15 without obstacles and during the dismounting, removed from the first openings 15. With the mounted door locking system, the mounting pins 9 are nevertheless securely fixed in the first openings 15.

[0048] Making reference to FIG. 5 and FIG. 7, the resetting unit 11 a can be mounted in the first door handle unit 4a in two positions. The resetting unit 11 a—as already explained above—comprises the stop plate 12a with the stop arms 13 and with the coil springs 14.

[0049] In FIG. 5 and FIG. 7, the stop plate 12a is mounted in the first position. The respective stop arm 13 is adjacent to a first stop 24 of the first mounting plate 8a. The respective coil spring 14 supports itself on the respective stop arm 13 and on a second stop 25 of the first mounting plate 8a. Because of this, the door handle 5a can be manually adjusted from the open position into the locking position by way of the resetting unit 11a in an opposite second direction of rotation DR2. The directions of rotation DR1 and DR2 lie in a radial plane oriented transversely to the mounting axis 10 and circulate about the mounting axis 10.

[0050] In a second position of the stop plate 12a—not shown here—the respective stop arm 13 can be mounted adjacent to the second stop 25 of the first mounting plate 8a. The coil spring 14 then supports itself on the respective stop arm 13 on the first stop 24 of the first mounting plate 8a. Because of this, the door handle 5a can be manually adjusted from the locking position into the open position in the second direction of rotation DR2 and from the open position into the locking position by the resetting unit 11a in the first direction of rotation DR1.

[0051] Making reference to FIG. 3 and FIG. 4, the resetting units 11a and 11b are formed identically to one another and differ from one another by the position of the stop plates 12a and 12b. In the first door handle unit 4a, the stop plate 12a is mounted in the first position and in the second door handle unit 4b the stop plate 12b is mounted in the second position. Since the door handle units 4a and 4b are arranged transversely to the mounting axis 10 mirrored to one another, the door handles 5a and 5b can be jointly adjusted between the locking position and the open position in the respective direction of rotation DR1 and DR2.

[0052] In summary, the door locking system 1 according to the invention can be mounted and dismounted in a simplified manner. The mounting for a user is limited to sliding the mounting plates 8a and 8b together with the pre-assembled door handle units 4a and 4b and pivoting the cover plate 6a into the blocking position about the mounting axis 10. The disassembly can take place simplified in the same manner.
