The carrying handle comprises a handle strip and two terminal legs, which are articulated to the narrow side of the container. The legs are subdivided into two portions, which are interconnected by means of an intermediate joint. The articulation axis of the intermediate joint and of the container side joint are parallel to the handle strip. The leg portions are bent in the inoperative position of the carrying handle, so that they come to rest parallel to one another. Thus, the legs are shortened in the inoperative position, so that they do not project over the outer edges, particularly in the case of narrow containers and are instead located within the predetermined dimensions.

Two parts of a case hinge are detachably interconnected, i.e. the hinge pin of one part and the hollow cylinder of the other part can be disengaged by axial displacement. Moreover, the hinge pin is rotatably and axially displaceably mounted on the associated hinge part and is pretensioned in an axially resilient manner. It is provided on its free end with a rotation preventer, which engages in non-rotary and axially detachable manner with the other hinge part. On opening and closing the case the hinge pin consequently necessarily performs a rotary movement. In its bearing-side portion, the hinge pin is provided with a radial stop pin, which locks in a bearing-side indentation under a predetermined angle as a result of spring tension and consequently detachably secures the two hinge parts under a predetermined opening angle.

A profile frame of a folding door and the associated cabinet-side door frame for a cabinet are described. The profile of the cabinet-side and folding-side vertical beam has a diagonally outwardly open cavity covererd on its end faces by bearing eyes arranged on the horizontal beams. The associated door-side vertical beam is provided with an arcuate step extending longitudinally between the bearing eyes and which is integrated in externally flush manner into the recess of the cabinet-side vertical beam. The arcuate step is coaxial to the bearing eyes and receives the hinge bolts located there. The bolt-side vertical beam of the folding door is preferably provided with a swing bolt, which cooperates over the entire length of the vertical beam with a cabinet-side shoulder and which is operated by means of an eccentric bolt.

A lock hook for a door of a computer cabinet is described. The lock hook is pivotable about a pivot axis into a closed and an open position. Commonly, locking devices project out of the main surface of the door of computer cabinets when the lock hooks thereof are in the open position. The present invention solves this problem by pivoting the lock hook completely into an opening in the main surface of the door.
