Device Support

Abstract

A device support comprises a cabinet frame that is formed by metal hollow profiles ( 11 ) and that has at least in one of its corners a parallelepiped corner connector element ( 30 ) connected to at least one of the hollow profiles ( 11 ) by means of a screw. At least one outside face of the corner connector element ( 30 ) is configured as a securing face which has a guiding shoulder ( 34 ) with at least two parallel outer edges ( 34.1 ), resting on inner peripheral surfaces of the hollow profile ( 11 ). The hollow profiles ( 11 ) have a closed cross-section. A throughbore runs from every securing face for receiving the screw shank and continues, starting from a support shoulder in the interior of the corner connection element ( 30 ), along a passage recess ( 32 ) which extends to an outside face of the corner connector element opposite the securing face.

1 . A device support, comprising a cabinet frame, which is formed from metal hollow profiles and which has at least at one of its corners a cuboidal corner connector element that is connected to at least one of the hollow profiles via a screw connection, wherein at least one outer side of the corner connector element is designed as an attachment side, having at least one guide shoulder with at least two parallel outer edges that rest on the inner perimetral surfaces of the hollow profile, the improvement wherein
 the hollow profiles exhibit a closed cross-section,   a throughhole for receiving the screw shaft runs from every attachment side and continues, starting from the support shoulder, in the inside of the corner connector element in a feed-through cutout, extending to an outer side of the corner connector element located opposite the attachment side, and   the screw connection comprises at least one screw to be aligned in the longitudinal direction of the hollow profile and a receiving element with a threaded hole located in the interior of the hollow profile, whereby the screw is held in the feed-through cutout by its screw head, which exhibits an inside drive, and the screw shaft extends into the interior of the hollow profile to the receiving element.   
   
   
       2 . A device support as defined in  claim 1 , wherein the corner connector element exhibits at least two attachment sides oriented at a right angle to each other and at least two intersecting feed-through cutouts, whereby the depth (T) of at least one of the feed-through cutouts between the respective support shoulder and the envelope curve of the intersecting feed-through cutouts corresponds at least to the height of the screw head. 
   
   
       3 . A device support as defined in  claim 2 , wherein a screw exhibits a screw head that fills the feed-through cutout entirely and that exhibits an interior cutout that is formed as an inner drive at the side that is facing the screw shaft and above is provided at least in part with a female thread. 
   
   
       4 . A device support as defined in  claim 3 , wherein the receiving element can be placed in two placement cutouts that are inserted in the hollow profile perpendicular to the longitudinal axis at opposite sides, whereby the receiving element comprises at its end sides at least two lay-on edges that are oriented mirror-inverted to each other. 
   
   
       5 . A device support as defined in  claim 4 , wherein the edge of the placement cutouts adjacent to the corner connector element the area of the receiving element facing this edge is at least partially serrated. 
   
   
       6 . A device support as defined in  claim 4 , wherein the receiving element exhibits a clamp-shaped configuration with two lay-on edges directed toward the inside. 
   
   
       7 . A device support as defined in  claim 4 , wherein the receiving element exhibits a T-shaped configuration with two lay-on edges directed toward the outside. 
   
   
       8 . A device support as defined in  claim 4 , wherein the receiving element exhibits two grooves with a width that corresponds to the wall thickness of the hollow profile. 
   
   
       9 . A device support as defined in  claim 1 , wherein the receiving element is designed as a plate element that is welded to the inside of the hollow profile. 
   
   
       10 . A device support as defined  claim 1 , wherein the receiving element can be pre-loaded when screwing in the screw. 
   
   
       11 . A device support as defined in  claim 1 , wherein the cabinet frame is cuboidal. 
   
   
       12 . A device cabinet as defined in  claim 11 , wherein corner connector elements are arranged at each of the four upper corners of the cuboidal cabinet frame that are each connected to three profiles via screw connections, and wherein in the lower section of the cuboidal cabinet frame, a rectangular base frame is provided, where its four corners are each connected with a vertically arranged profile of the cuboidal cabinet frame via weld or screw connection. 
   
   
       13 . A device cabinet as defined in  claim 11 , wherein corner connectors are arranged at all eight corners of the cuboidal cabinet frame that are each connected to three profiles via a screw connection. 
   
   
       14 . A device cabinet as defined in  claim 11 , wherein the corner connectors are cube-shaped. 
   
   
       15 . A device cabinet as defined in  claim 11 , further comprising at least one covering plate suspended from the cabinet frame, wherein
 the covering plate is provided with at least one locking strap,   the locking strap protrudes beyond a circumferential side edge of the covering plate   and the locking strap rests on an outer surface of the profile of the cabinet frame.
