Abstract

The invention relates to a hinge for a switchgear cabinet housing, comprising a first and a second hinge half, which can be connected to each other by means of a hinge pin and which can be pivoted relative to each other about a longitudinal axis of the hinge pin, the hinge pin extending only into the first or the second hinge half in a release position and extending into both the first and the second hinge halves in a locking position, wherein the hinge pin is releasably locked by means of at least one spring clip both in the release position and in the locking position. The invention further relates to a corresponding switchgear cabinet housing and to a corresponding method for mounting a door element on a switchgear cabinet body.

First claim

The invention claimed is:

1. A hinge, comprising:
a first hinge half, having a first and second hinge pin sleeves aligned along a longitudinal axis;
a second hinge half;
a hinge pin aligned along the longitudinal axis, the hinge pin having a release position in which the hinge pin is located only within one of the hinge pin sleeves, and a locking position in which the hinge pin is located within both hinge pin sleeves, the hinge pin having at least one groove about its outer circumference;
a spring clip engaging the hinge pin in both the locking and release positions, the spring clip having a tensioning section which extends along an outer circumference of one of the hinge in sleeves, the tensioning section having two opposing ends, one end of the tensioning section having a locking catch extending in a radial direction of the hinge pin sleeve, and the other end of the tensioning section having a counter holder;
the spring clip being a stamped metal part;
the locking catch extending approximately 90 degrees inward from the first opposing end of the tensioning section, to engage said groove in the hinge pin; and
the counter holder being substantially opposite the locking catch and is formed with two planar portions, the first planar portion is bent from the second opposing end of the tensioning section at an oblique angle inward of the tensioning section, and the second planar portion is bent from an end of the first planar portion at an oblique angle outward of the tensioning section.

2. The hinge as claimed in claim 1 , in which the hinge pin comprises two grooves, spaced apart in relation to each other along its longitudinal axis, wherein the spring clip engages in the first groove in the release position and engages in the second groove in the locking position.

3. The hinge as claimed in claim 1 , further comprising a second spring clip, one spring clip being located on each hinge pin sleeve.

4. The hinge as claimed in claim 3 , in which the hinge pin sleeves are arranged at a distance in relation to each other along the longitudinal axis of the hinge pin, wherein in the release position, one of the ring grooves of the hinge pin is engaged by only the first spring clip.

5. The hinge as claimed in claim 1 , in which the locking catch extends through the hinge pin sleeve through a passage extending in the radial direction of the hinge pin sleeve and is pre-tensioned in the radial direction via the tensioning section.

6. The hinge as claimed in claim 1 , in which the locking catch comprises an intake bevel.

7. The hinge as claimed in claim 1 , in which the counter holder extends through the hinge pin sleeve in a further passage extending in the radial direction of the hinge pin sleeve.

8. The hinge as claimed in claim 6 , in which the further passage is arranged offset around the longitudinal axis by an angle of at least 90 degrees in relation to the passage for the locking catch.

9. A switchgear cabinet housing having a switchgear cabinet body and a door element secured thereon via at least one hinge as claimed in claim 1 .
