Switchgear cabinet with frame

The invention relates to a switchgear cabinet having a housing consisting of frame legs and Corner frames, the open sides of which are fixed by means of the Side walls, rear wall, floor panel, deck plate and at least one door Closable or closed, and wherein at least the vertical Are bevelled in the region of their outer edges and thereby A receptacle for bent edges of the side walls and the door.

Such a control cabinet is known from FR 2 697 300. With these Known switchgear usually form two perpendicular to one another Standing profile sides of the frame legs Outside the frame frame And an outer edge. For the hinge of the door are therefore Hinges on the vertical frame legs. On the Closing side of the door are for the closing device attached to the door Additional clasping elements. This is often the stop side of the door On the frame frame and can not be installed at the place of installation of the control cabinet Can be easily changed. In addition, as a rule, Which open side of the frame frame should be closable with the door.

It is an object of the invention, in the case of a control cabinet of the type mentioned at the outset The door without special hinge and clasp elements on the frame frame On the frame frame, the stop and closing side being arranged in a simple manner And wherein the one side of the frame frame is interchangeable Provided on the opposite side of the Frame frame.

This object is achieved according to the invention in that the corner connectors Cover the shoulders of the frame legs and face the shots Are provided with plug - in receptacles or hinge pins, in that the door is fixed on the The hinge side is provided with hinge pins or plug-in receptacles, which in FIG Plug-in receptacles of the corner connectors can be introduced or inserted into the The hinge pins of the door being insertable or inserted, and the door Is provided on the closing side with locking bolts, which are closed by means of a closing device Can be inserted into plug-in receptacles of the corner connectors and can be removed again are.

In this embodiment of the frame limbs and corner connectors, the Corner connectors also provide the functions necessary for hinging and closing the door required are. Only plug-in receptacles are used for the corner connectors Or hinge bolts. The frame legs need for the door No longer have any hinge or clasping elements. The on the frame legs In the area of ​​the external edges provide sufficient Place, Angled edge portions of the side walls and the door To be recorded.

According to one embodiment, it is provided that the Frame leg two perpendicular to each other Profile sides, the outer sides of the frame frame , And in that these profile sides in the region of the outer edge Via a connecting profile section , Each of which is below 135 ° to these profile pages. In this embodiment, the frame leg can be used for both Adjoining sides of the frame frame as Hinge or closing side of a door.

The receptacle in the area of ​​the outer edge of the frame legs Can be increased by the fact that the profile sides overlap Perpendicular to their standing transition profile sections Into the connecting section.

It is provided that the corner connectors are arranged vertically Have mutually standing surfaces which are parts of the Outer edges of the frame frame, Surfaces flush with the outsides of the adjacent Side walls and the closed door, then Is flush in the corner areas of the control cabinet Concluded.

The attachment of the side walls, the rear wall, the The floor plate and the cover plate are made according to a Design by screwing on the corner connectors. It is also possible to attach to the frame legs, Without the wall elements being provided with fastening holes for Fastening screws.

Attaching the door to the frame frame is thereby achieved Makes it easier for the hinge pins or the locking pins In bearing sleeves attached to the door And / or are held.

The articulation of a door can also be performed in a simple manner In that the hinge pins are held by bearing sleeves Of the door in plug-in receptacles of the corner connectors And held therein by fit and / or press fit are.

The invention is described with reference to the drawings, in which: FIG Illustrated in more detail. It show:<dl tsize="6"><dt>FIG</dt><dd>A part of a frame frame with the Front, right frame leg, to the one Side wall and a door, and</dd><dt>FIG</dt><dd>A partial view in the region of the lower Corner connector at the front, right Frame legs.</dd></dl>

Of a frame rack 10 in FIG. 1, only the vertical Frame legs 11 and 12 at the front right corner and Of the rear left corner. At the top of the Vertical frame leg 11 are connected via a corner connector 20 the horizontal frame legs 13 and 14 are connected. In the lower area are the horizontal frame legs 15, 16, 17 and 18, of which the frame legs 15 and 18 via a further corner connector 20 with the Lower end of the vertical frame leg 11 are. The side walls 40 and 44 are connected to the corner connectors 20, the corners being chamfered and without edges In these areas, such as the corner 43 of the Side wall 40. The edge portions 41 and 45 of the side walls 40 and 44 project into receptacles 70 of the Frame legs. As FIG. 2 shows, the frame legs In the region of their outer edge The connecting portion 53 and the transition portions 54 and 55 a receptacle 70. The corner connector 20 is covered With a shoulder 24, this receptacle 70 Corner connector 20 carries a plug-in receptacle 21 Facing surfaces 22 and 23 of the corner connectors 20 are flush with the outer sides of the switchgear cabinet, Ie, the outer sides of the connectors at the corner connectors 20 Side walls 40 and 44, rear wall 46 and door 30. The contact surfaces 25 and 26 for these parts are reversed Their thickness opposite the surfaces 22 and 23 at the corner connector 20 to achieve the flush. To the The contact surfaces 25 and 26 are also screwed together Threaded receptacles 27 and 28.

The plug connections 65 of the corner connectors 20 are in receptacles 62 and 63 of the frame legs and inserted therein . These receptacles 62 and 63 are formed by several times Bent portions 56, 58, 59 and 57, 60, 61, respectively. The triple bent portions 56 and 57 are formed Outside open receiving grooves for sealing elements. These Receiving grooves 56 and 57 lie in the region of the vertical Profile faces 51 and 52 on which the Side walls 40 and 44, the rear wall 46, the door 30 and The bottom and cover plates (not shown).

To hinge the door 30, hinge bolts are used, Which can be adjusted and fixed, for example, in bearing sleeves of the door 30 are. When the door 30 is touched, Insert the two hinge pins into the Plug receptacles 21 of the two associated corner connectors 20 And fixed in the established position.

The fixing can be effected in the bearing sleeve of the door 30 Or in the plug-in receptacle 21 of the corner connectors 20.

Have the side walls 40 and 44, the rear wall 46, and the Door 30, edge portions 41, 45, 47 and 32, respectively 33, then they are placed in the receptacles 70 of the frame legs 11 to 18 place.

On the closing side, the door 30 carries one Closing device 31, which can be used, for example, as a push rod lock Can be formed. The pushrods serve as Closing bolts 35 and are in bearing sleeves of the door 30 Adjustably guided and held. In the closed state of the Closing device 31, the pushing ends as Closing bolts 35 into the plug-in receptacles 21 of the adjacent Corner connector 20. When opening the Closing device 31, the push rod ends are turned off The plug-in receptacles 21 of the corner connectors 20 And the door 30 hinged on the hinge side Are opened.

The attachment of the side walls, the rear wall, the Floor plates and the cover plate can also be used from the outside Invisible fastening means.
