Abstract

The present invention relates to a cable locking system which comprises a cable and a cable clamp having a first lever with a planar surface and having a second lever with a planar surface. The second lever is connected to the first lever in an articulated manner such that the two levers can be moved between a release position in which they are angled toward one another and a clamping position in which their planar surfaces contact one another and together define an opening for clamping the cable whose clear opening area decreases with an increasing approach to the clamping position. The first lever is interspersed in a locking region by a plurality of passage openings which are aligned with corresponding passage openings in the clamping position by which the second lever is interspersed in a locking region. The first lever furthermore has at least one angled section which rises from the planar surface such that it clampingly engages around a marginal section of the second lever in the clamping position and which is spaced apart from the joint at which the two levers are connected to one another by a smaller amount than each of the passage openings, but by a larger amount than the cable clamping opening defined by the two levers.

First claim

The invention claimed is:

1. A cable locking system, which comprises a cable and a cable clamp, the cable clamp having a first lever with a planar first lever surface and a first arcuate slit formed in the first lever surface, and the cable clamp having a second lever which has a planar second lever surface and a second arcuate slit formed in the second lever surface, in which the second lever is connected to the first lever in an articulated manner by a pivot joint such that the first and second levers can be moved between a release position in which they are angled with respect to one another and a clamping position in which the planar first lever surface contacts the planar second lever surface and the first and second arcuate slits together define a cable clamping opening for clamping the cable, the cable clamping opening having a clear opening area that decreases with an increasing approach to the clamping position,
wherein the first lever is interspersed in a locking region by a plurality of passage openings which are aligned with corresponding passage openings in the second lever in the clamping position, by which the second lever is interspersed in a locking region and has at least one angled section which rises from the planar first lever surface such that it clampingly engages around a marginal section of the second lever in the clamping position and which is spaced apart from the joint at which the first and second levers are connected to one another by a smaller amount than all of the passage openings of the cable locking system, but by a larger amount than the cable clamping opening defined by the first and second levers, the at least one angled section located between the locking region and the pivot joint.

2. The cable locking system in accordance with claim 1 ,
that is used for locking machines, units or plants, for servicing, cleaning or maintenance.

3. The cable locking system in accordance with claim 1 ,
wherein the first and second levers are of identical design.

4. The cable locking system in accordance with claim 1 ,
wherein the respective locking region is formed at a free end of the respective first or second lever.

5. The cable locking system in accordance with claim 1 ,
wherein the first and second levers have a section with a reduced width radially inwardly of the locking region.

6. The cable locking system in accordance with claim 5 ,
wherein the section of reduced width is formed by mutually oppositely disposed arcuate cut-outs.

7. The cable locking system in accordance with claim 5 ,
wherein the angled section is located at least partly in the region of the section of reduced width.

8. The cable locking system in accordance with claim 5 ,
wherein the angled section of the respective first and second lever is spaced apart from the joint at which the first and second levers are connected to one another in an articulated manner by a smaller amount than the section of reduced width, but by a larger amount than the cable clamping opening defined by the first and second levers.

9. The cable locking system in accordance with claim 5 ,
wherein the respective locking region has a rectangular design.

10. The cable locking system in accordance with claim 9 ,
wherein the respective locking region has a rectangular design having rounded corners.

11. The cable locking system in accordance with claim 1 ,
wherein the first and second levers each have a head section at their end at which they are connected to one another in an articulated manner, the head section being rounded in circular form over an angular range of more than 180°.

12. The cable locking system in accordance with claim 1 ,
wherein the first and second levers each have a head section at their end at which they are connected to one another in an articulated manner, the head section being rounded in circular form over an angular range of more than 200°.

13. The cable locking system in accordance with claim 1 , wherein the first and second levers each have a head section at their end at which they are connected to one another in an articulated manner, the head section being rounded in circular form over an angular range of more than 220°.

14. The cable locking system in accordance with claim 1 , wherein the first and second levers each have a head section at their end at which they are connected to one another in an articulated manner, the head section being rounded in circular form over an angular range of approximately 240°.

15. A cable clamp for a cable locking system, the cable clamp having a first lever with a planar first lever surface and a first arcuate slit formed in the first lever surface, and the cable clamp having a second lever which has a planar second lever surface and a second arcuate slit formed in the second lever surface, in which the second lever is connected to the first lever in an articulated manner by a pivot joint such that the first and second levers can be moved between a release position in which they are angled with respect to one another and a clamping position in which the planar first and second lever surfaces contact one another and the first and second arcuate slits together define a cable clamping opening for clamping a cable, the cable clamping opening having a clear opening area that decreases with an increasing approach to the clamping position, wherein the first lever is interspersed in a locking region by a plurality of passage openings which are aligned with corresponding passage openings in the second lever in the clamping position, by which the second lever is interspersed in a locking region and has at least one angled section which rises from the planar first lever surface such that it clampingly engages around a marginal section of the second lever in the clamping position and which is spaced apart from the joint at which the first and second levers are connected to one another by a smaller amount than all of the passage openings of the cable clamp, but by a larger amount than the cable clamping opening defined by the first and second levers, the at least one angled section located between the locking region and the pivot joint.

16. The cable clamp in accordance with claim 15 , that is used for locking machines, units or plants, for servicing, cleaning or maintenance.
