Abstract

A door lock mechanism for actuation of the locking slide of a disconnector on a control box, includes a setting mechanism, that may be disposed between a locking position and a released position and that is pre-loaded toward the locking position, wherein the setting mechanism comprises a shaft that is pivoted around a rotation axis, wherein the shaft comprises at a first end a first lever that may be coupled with the locking slide of a disconnector, and wherein the shaft comprises at a second end opposing the first end a second lever having an actuating bolt so that upon pivoting the second lever the first lever conducts a respective pivoting; and a locking nose to be mounted at the inside of a control box door wherein the locking nose comprises starting from its tip an approach slope turning into a catch that turns into a contour slope so that upon closing the control box door the actuating bolt is guided along the contour slope in direction of the release position and against the pre-load.

First claim

What is claimed is:

1. A door lock mechanism in combination with a disconnector with a locking slide on a control box with a control box door, for actuation by the locking slide of the disconnector, said combination comprising
a setting mechanism disposable between a locking position and a released position and that is pre-loaded toward the locking position, wherein the setting mechanism comprises a shaft that is pivoted around a rotation axis, wherein at a first end of the shaft, the shaft comprises a first lever that is coupled with the locking slide of the disconnector on the control box, and wherein the shaft comprises, at a second end opposing the first end, a second lever having an actuating bolt such that pivoting of the second lever causes a corresponding pivoting of the first lever; and
a locking nose mounted on an inside of the control box door of the control box, wherein the locking nose comprises, starting from a tip thereof, an approach slope leading into a catch that leads into a contour slope so that upon closing of the control box door toward a closed position, the actuating bolt of the second lever is guided along the approach slope in a direction of the released position and against the pre-load.

2. The combination according to claim 1 , wherein the second lever is connected to the shaft by means of a selectively releasable and lockable coupling, which is configured to connect the second lever in varying positions in relation to the first lever.

3. The combination according to claim 1 , wherein the first lever is a stepped molded part that is mounted by means of a lower ledge on the shaft and that comprises a passage at its upper ledge engaged by a connecting bolt that is connectable with the locking slide of the disconnector.

4. The combination according to claim 3 , wherein the passage is a slotted hole comprising an open end, so that the first lever comprises a fork by means of which the first lever engages the connecting bolt.

5. The combination according to claim 1 , wherein the locking nose comprises an undercut at its transition between the approach slope and the catch.

6. The combination according to claim 1 , wherein the setting mechanism comprises a limiting slit describing a circular path section around the rotation axis and along which the second lever is guided.

7. The combination according to claim 1 , wherein the setting mechanism comprises a marking indicating a desired position of the second lever when the setting mechanism is located in the locking position.

8. The combination according to claim 1 , wherein the second lever comprises a plug extending along the rotation axis and by which the second lever is connected with the shaft, wherein the plug is connected with a cantilever of the second lever extending radially with respect to the rotation axis, and wherein the actuating bolt is connected to the cantilever parallel to and displaced from the plug.

9. A control box arrangement comprising the door lock mechanism in combination with the disconnector with the locking slide on the control box according to claim 1 , and further comprising a frame having the control box door that is pivotably hinged at a first side of the frame, and wherein a disconnector hood is mounted at a second side of the frame adjoining the first side in an orthogonal manner, wherein
the disconnector is mounted at a face side of the disconnector hood and extends into an interior of the disconnector hood by the locking slide and the disconnector includes an actuating slide for an electric switch,
wherein the setting mechanism is mounted at a vertical profile section of the frame, wherein a connecting bolt is connected with the locking slide and engages a passage of the first lever and wherein the actuating bolt of the second lever extends into an unobstructed opening of the frame so as to cooperate with the locking nose mounted on the inside of the control box door,
and wherein the locking nose is mounted on the inside of the control box door at a vertical side of the control box door that is located opposing the first side of the frame to which the control box door is pivotably hinged in such a way that upon closing of the control box door toward the closed position, the locking nose guides the actuating bolt with its approach slope.

10. The control box arrangement according to claim 9 , wherein the actuating bolt engages, when the control box door has moved to the closed position, a position on the contour slope in which the setting mechanism is located in the release position, and when the setting mechanism is in the locking position, the bolt is located in the catch.

11. The control box arrangement according to claim 9 , wherein the disconnector is releasable in a closed position by means of a pivoting of the control box door.

12. The control box arrangement according to claim 9 , wherein the door lock mechanism is constructed symmetrically, wherein the control box door comprises first and second edges, and either the first or the second edge of the control box door can comprise hinges, and the door lock mechanism is mountable independent of the edge of the control box door comprising hinges.

13. The door lock mechanism according to claim 3 , wherein the stepped molded part is a part molded from sheet metal.

14. A door lock mechanism for a control box with a control box door, wherein:
the door lock mechanism is configured to be actuated by a locking slide of a disconnector on the control box;
the door lock mechanism comprising:
a setting mechanism disposable between a locking position and a released position and that is pre-loaded toward the locking position, wherein the setting mechanism comprises a shaft that is pivoted around a rotation axis, wherein at a first end of the shaft, the shaft comprises a first lever that is coupled with the locking slide of the disconnector on the control box, and wherein the shaft comprises, at a second end opposing the first end, a second lever having an actuating bolt such that pivoting of the second lever causes a corresponding pivoting of the first lever; and
a locking nose mounted on an inside of the control box door, wherein the locking nose comprises, starting from a tip thereof, an approach slope leading into a catch that leads into a contour slope so that upon closing of the control box door, the actuating bolt of the second lever is guided along the approach slope in a direction of the released position and against the pre-load.
