DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to a switchgear cabinet with a cabinet frame formed of frame legs, which can be closed by a cover, side elements, a rear wall and a cabinet door.
The cabinet frame is assembled from twelve frame legs, which are connected with each other on the comers where they meet by corner connectors. To enclose the cabinet frame, the side walls, the cover and the rear wall are fastened in such a way that their beveled edges reach around the individual frame legs.
SUMMARY OF THE INVENTION
It is one object of this invention to provide a switchgear cabinet of the type mentioned above with corner area visual and functional elements that can be fastened in a simple manner.
The object of this invention is attained with horizontal depth struts that are embodied as angled profile sections open toward the exterior. The cover and/or the side elements have beveled edges which at least partially cover the outside of the profiled sections, wherein a receptacle is formed by the beveled edge and the outside of the receptacle into which a plug-in neck of a corner element is inserted.
A corner element can be applied and subsequently fixed in place within the receptacle in an area between the depth strut and the beveled edge of the cover or the side wall. In addition to fixing the corner element in place, the receptacle also assumes a positioning function which permits an exact alignment of the corner element. The corner element itself can be designed to meet the individual visual and functional requirements.
In accordance with one preferred embodiment of this invention, the depth strut is formed as an angled profile section with two legs, to which a horizontal and a vertical frame leg are attached, and the cover has the beveled edge which extends toward both ends of the legs, so that a receptacle which is triangular in cross section is formed between the beveled edge and the two legs of the angled profile section.
The frame legs can be easily screwed to the depth strut. Screw receptacles are cut into the depth strut, into which the fastening screws can be inserted and can be screwed into threaded receivers of the frame legs. The corner element can be used to cover the screw heads. Subsequently the corner element is fixed in place in the generally triangular receptacle with a generally triangular plug-in neck so the corner element cannot be rotated.
In a preferred embodiment of this invention at least one upper corner element and one lower corner element of an associated side of the frame body has a base element adjoining the plug-in neck, which is extended beyond the front of the switchgear cabinet and which has receptacles or necks for door hinges and/or a locking bar arrangement. If, for example, the door hinges are alternatively on the other side of the cabinet frame, the corner elements are simply changed to the other side. It is then possible to fix the door on the corner elements at a position which is rotated by 180.degree.. It is also possible to have the door hinges on one side of the cabinet frame by using two corner elements and the receptacle of the locking bar arrangement on the other side.
In order to achieve a visual finish on the rear of the switchgear cabinet, for example, it is also possible for the base elements to end flush with the front or rear of the cabinet frame.
If the plug-in necks of the corner elements make a transition into the base element by way of shoulders, the insertion movement of the corner elements can be limited. It is thus possible to achieve the exact position of the corner elements. This is primarily of importance for the connection of the corner elements for hinging a door or for receiving the locking bar arrangement.
For sealing the switchgear cabinet, seals are inserted into the longitudinal grooves of the horizontal and vertical frame legs, on which the edges of the cover and the side elements press.
For sealing the rear wall and the switchgear cabinet door the horizontal and the vertical frame legs can have fr
