DESCRIPTION OF THE INVENTION

[0052] FIG. 1 shows a system 1 according to the invention comprising a swivel lever device 2 and a corresponding key unit 3 in a perspective view. The swivel lever device 2 comprises a housing 4 and a swivel lever 5. The swivel lever 5 adopts an actuating position in FIG. 1. In the actuating position, the swivel lever 5 can be pivoted relative to the housing 4 about an actuating axis A.sub.B. In this way, a closure apparatus 6 (not represented in FIG. 1) can be actuated by means of the swivel lever 5.

[0053] In addition to the housing 4 and the swivel lever 5, the swivel lever device 2 has a locking mechanism 7. The locking mechanism 7 comprises a plurality of locking elements 8, which are in the present case formed by locking magnets 9. In this case, the locking elements 8 are arranged in the exemplary embodiment represented and in this respect preferred on opposing sides of the longitudinal axis L.sub.SH of the swivel lever 5. In FIG. 1, the locking elements 8 adopt unlocking positions in which the locking elements 8 are each received in an unlocking receptacle 10 of the swivel lever 5. In this case, only a part of the unlocking receptacles 10 of the swivel lever 5 is occupied with locking elements 8. In order to increase security, it could alternatively be provided that a large part of the unlocking receptacles 10, in particular all unlocking receptacles 10, is occupied with a locking element 8.

[0054] The locking mechanism 7 comprises two retaining elements 11 in the present case. These are designed as wire ropes in the exemplary embodiment represented and in this respect preferred. The retaining elements 11 are arranged on opposing longitudinal sides of the swivel lever 5 and held on the swivel lever 5 at their longitudinal ends. For this purpose, the longitudinal ends of the retaining elements 11 are inserted into receptacles of the swivel lever 5 and held on the swivel lever 5 in the receptacles in a manner not represented via spring means. In FIG. 1, the retaining elements 11 adopt retaining positions in which the retaining elements 11 each partially cover the openings of the unlocking receptacles 10 arranged on the corresponding side of the swivel lever 5. This prevents the locking elements 8 from accidentally slipping out of the unlocking receptacles 10. Above the retaining elements 11, the swivel lever 5 has two guide elements 12, which extend along the longitudinal axis L.sub.SH of the swivel lever 5 in the exemplary embodiment represented and in this respect preferred. In this case, the guide elements 12 each form an undercut 13, behind which the key unit 3 can engage.

[0055] The housing 4 has a plurality of locking receptacles 14, which are formed into opposing side walls 15 of the housing 4 in the exemplary embodiment represented and in this respect preferred. In this case, the locking receptacles 14 are arranged spaced apart from one another along the longitudinal axis L.sub.G of the housing 4. The rear walls of the locking receptacles 14 are in the present case formed by two securing elements 16 in the form of metallic plates, which are provided for interaction with the locking elements 8 designed as locking magnets 9. The securing elements 16 are thereby received in the side walls 15 of the housing 4. In addition, the housing 4 has a plurality of adjustment elements 17. The adjustment elements 17 are provided for positive-locking adjustment of the retaining elements 11 designed as wire ropes. In this case, the adjustment elements 17 are formed as projections which extend inwards from the inner sides of the side walls 15 of the housing 4.

[0056] The key unit 3 has a plurality of unlocking magnets 18 which are received in corresponding receptacles 19 of the key unit 3. In this case, the receptacles 19, in the exemplary embodiment represented and in this respect preferred, are arranged in opposing side walls 20 of the key unit 3 and are designed as through openings. Alternatively, however, it could also be provided that the receptacles 19 are closed outwards such that the unlocking magnets 18 are inaccessible from the outside.

[0057] FIG. 2 shows the key unit 3 in a perspective view from below. The key unit 3 forms a recess open to the underside, with which the key unit 3 can be pushed along the longitudinal axis L.sub.SH of the swivel lever 5 onto the swivel lever device 2 or the swivel lever 5. In this case, the key unit 3 has two retaining elements 21 on the opposing inner sides of its side walls 20, which can engage behind the undercuts 13 formed by the two guide elements 12 of the swivel lever 5 when pushing the key unit 3 onto the swivel lever 5.

[0058] From the actuating position represented in FIG. 1, the swivel lever 5 can be pivoted relative to the housing 4 about an axis, which is arranged in the present case perpendicular to the actuating axis A.sub.B, into the latched position represented in FIG. 3A-C. When pivoting the swivel lever 5 into the latched position, the retaining elements 11 in the form of the wire ropes come into contact with the adjustment elements 17 designed as projections. As a result, the retaining elements 11 are adjusted upwards in sections and are thus adjusted from the retaining position represented in FIG. 1 to a release position, in which the retaining elements 11 release the openings of the unlocking receptacles 10. The locking elements 8 in the form of the locking magnets 9 are then pulled by the magnetic interactions between them and the locking elements 16 designed as metal plates in the direction of the securing elements 16. In this way, the locking elements 8 are automatically adjusted from the unlocking position represented in FIG. 1 to a locking position, in which the locking elements 8 engage into the locking receptacles 14.

[0059] FIG. 3A-C show the swivel lever device 2 in different views, wherein the swivel lever 5 is in each case represented in the latched position. FIG. 3A shows the swivel lever device 2 in a perspective view. In the latched position, the swivel lever 5 is partially received in the housing 4. In this case, pivoting of the swivel lever 5 about the actuating axis A.sub.B is blocked in an positive-locking manner by the two side walls 15 of the housing 4.

[0060] FIG. 3B shows the swivel lever device 2 in a side view, wherein the unlocking receptacles 10 of the swivel lever 5 are represented with dashed lines. The swivel lever 5 is connected to a coupling element 22 in a torque-resistant manner about the actuating axis A.sub.B. In this case, the coupling element 22 is designed to connect the swivel lever 5 to a closure apparatus 6 not represented in FIG. 3, for example in the form of a bolt closure means and/or a bar closure means. The housing 4 has two fastening elements 24 projecting from its underside 23, which in FIG. 3 are only represented schematically. In the exemplary embodiment represented and in this respect preferred, these fastening elements 24 each form an internal thread into which a screw 25 is screwed.

[0061] FIG. 3C shows the swivel lever device 2 in a sectioned view along the section plane IIIC-IIIC represented in FIG. 3B, wherein the locking elements 8 are represented in the respective locking position. In the locking position, the locking elements 8 in the form of the locking magnets 9 are partially received in the unlocking receptacles 10 formed by the swivel lever 5. In addition, the locking elements 8 engage in a positive-locking manner into the locking receptacles 14 formed by the housing 4. In this way, pivoting of the swivel lever 5 from the latched position (FIG. 3A-C) to the actuating position (FIG. 1) is blocked in a positive-locking manner. In this case, the locking elements 8 are held in the locking position by means of the magnetic interactions between them and the securing elements 16 received in the side walls 15 of the housing 4, in this case designed as metal plates. To adjust the swivel lever 5 from the latched position represented in FIG. 3A-C back to the actuating position represented in FIG. 1, the key unit 3 can be adjusted relative to the swivel lever device 2 or to the swivel lever 5 into the release position represented in FIG. 4A-B.

[0062] FIG. 4A-B show the system 1 in different views, wherein the swivel lever 5 is respectively represented in the latched position and the key unit 3 is respectively represented in the release position. FIG. 4A shows the system 1 in a perspective view. In the release position, the key unit 3 is pushed along the longitudinal axis L.sub.SH of the swivel lever 5 onto the swivel lever device 2 or the swivel lever 5. In this case, the key unit 3 is held on the swivel lever 5 in a positive-locking manner perpendicular to the longitudinal axis L.sub.SH of the swivel lever 5.

[0063] FIG. 4B shows the system 1 in a sectioned view along the section plane IVB-IVB represented in FIG. 4A, wherein the locking elements 8 are represented in the respective unlocking position. The unlocking magnets 18 received in the key unit 3 have a higher field strength than the locking magnets 9 of the swivel lever device 2. The locking magnets 9 are thus displaced from the locking position (FIG. 3C) to the unlocking position (FIG. 4B) by means of the magnetic interactions with the unlocking magnets 18. The unlocking magnets 18 thus press the locking magnets 9 into the unlocking positions against the magnetic attraction between the locking magnets 9 and the securing elements 16. The swivel lever device 2 can be unlocked in this way.

[0064] In the present case, the locking elements 8 of the swivel lever device 2 are designed in the same way, namely as cylindrical pins. However, the polarities of the locking elements 8 designed as locking magnets 9 differ in relation to the respective unlocking direction R.sub.E, in which the corresponding locking element 8 can be adjusted from the locking position (FIG. 3C) to the unlocking position (FIG. 4C). Thus, the locking magnets 9 have at the end pointing in the unlocking direction R.sub.E partially a south pole S and partially a north pole N. This can increase the security against the swivel lever device 2 being unlocked unauthorised.

[0065] In the present case, the key unit 3 is designed as a master key unit and has, in addition to the unlocking magnets 18, a master unlocking magnet 26. The unlocking magnets 18 and the master unlocking magnet 26 are thereby designed in the same way. In contrast to the unlocking magnets 18, however, no locking element 8 of the swivel lever device 2 is assigned to the master unlocking magnet 26. Further swivel lever devices different from the represented swivel lever devices 2 in regard to the position of their locking elements 8 can be unlocked by means of the master unlocking magnet 26. Thus, swivel lever devices 2 can also be unlocked with the key unit 3, which, in contrast to the swivel lever device 2 represented, have a locking element 8 at the position of the master unlocking magnet 26.

[0066] In the release position, the key unit 3 is connected via the holding elements 21 (FIG. 2) not visible in FIGS. 4A-B and the side walls 20 of the key unit 3 are connected in a positive-locking manner to the swivel lever 5 perpendicular to the longitudinal axis L.sub.SH thereof. Thus, the swivel lever 5 together with the key unit 3 can be adjusted from the latched position represented in FIG. 4A-B into the actuating position represented in FIG. 5 and pivoted about the actuating axis A.sub.B in this actuating position.

[0067] FIG. 5 shows the system 1 in a perspective view, wherein the swivel lever 5 is represented in the actuating position and the key unit 3 is represented in the release position. In the actuating position, the key unit 3 can be pulled down along the longitudinal axis L.sub.SH of the swivel lever 5 by the swivel lever and thus adjusted from the release position represented in FIG. 5 to a non-use position (see FIG. 1).

[0068] FIG. 6A-B each show a detail of the swivel lever device 2 in a sectioned view along the section plane VI-VI represented in FIG. 3B, wherein the swivel lever 5 is represented in an intermediate position (FIG. 6A) when adjusting from the actuating position to the latched position and in the latched position (FIG. 6B). When adjusting into the latched position, the retaining elements 11 come into contact with the adjustment elements 17 designed as projections and are thus automatically adjusted from the retaining position (FIG. 6A) to the release position (FIG. 6B), in which the retaining elements 11 release the openings of the unlocking receptacles 10. If the swivel lever 5 is adjusted by means of the key unit 3 not represented in FIG. 6A-B from the latched position (FIG. 6B) back into the actuating position, the retaining elements 11 are adjusted by the spring means, via which the retaining elements 11 are held on the swivel lever 5, from the release position (FIG. 6B) back to the retaining position (FIG. 6a).

[0069] FIG. 7 shows the swivel lever device 2 in a side view, wherein the swivel lever 5 is represented in the actuating position. The swivel lever device 2 is fastened to an access control device 27, for example in the form of a thin-walled door or a hatch, by means of the fastening elements 24 of the housing 4 and the screws 25. In this case, the swivel lever 5 is connected to a closure apparatus 6, which is designed in the present case as a rotary bolt closure means. By pivoting the swivel lever 5 about the actuating axis A.sub.B, a rotary bolt 28 of the rotary bolt closure means can be pivoted. In this way, the positive-locking closure between the rotary bolt 28 and a frame 29, on which the access control device 27 is held in an adjustable, in particular pivotable manner, can be released and the access control device 27 can thus be opened.
