Abstract

A switchgear cabinet with at least one cabinet door, which can be locked by a lock element of the switchgear cabinet body wherein, in a locked position of the cabinet door, a locking engagement between the lock element and a counter-lock element can be released by a triggering device, which is in an operative connection with the lock element or the counter-lock element via an actuating unit. So that the cabinet door can be opened in a simple way from the inside of the switchgear cabinet, the actuating unit of this invention is designed as a Bowden cable, with one end connected to the triggering device via a connecting element and an other end connected with the lock element or the counter-lock element. The triggering device has a rotary body which is pivotably seated about an axis of rotation. The end of the Bowden cable is fastened eccentrically offset with respect to the axis of rotation on the rotary body, and a lever with a handle is connected to the rotary body.

Dependent claims

In a switchgear cabinet having at least one cabinet door mounted to a cabinet body, wherein the cabinet door can be locked by a lock element of the cabinet body, in a locked position the cabinet door closes an opening in the cabinet body, a locking engagement between the lock element and a counter-lock element can be released by a triggering device that operates the lock element or the counter-lock element via an actuating unit, and in the locked position the triggering device is accessible from outside the cabinet body, the improvement comprising:

the actuating unit formed as a Bowden cable (30) with a first end connected to the triggering device (40) via a connecting element (32) and a second end connected with the lock element (17) or the counter-lock element (20);
the triggering device (40) having a rotary body (45) pivotably seated about an axis of rotation;
the first end of the Bowden cable (30) fastened to the rotary body (45) of the trigger device at a position eccentrically offset from the axis of rotation on the rotary body (45);
a lever (47) with a handle (48) connected to the rotary body (45), at least two cabinet doors (15) hingedly connected with the cabinet body, a first cabinet door of the at least two cabinet doors (15) maintained in the locked position by locking engagement between the lock element (17) and the counter-lock element (20), and the triggering device (40) maintained near the switchgear cabinet interior and accessible through the opening in the cabinet body.
