frame section 10 shown in fig1 is configured as a multi - chambered section including a support section 4 and a wall section 8 to facilitate construction of a framework 1 . sealing edging 12 is provided at right angles to the exterior 3 of framework 1 . a free space 13 is formed from an angularly - profiled section wall at a corner region 9 along an outer edge . a receiving cavity 11 is provided open to the inwardly facing side 14 of the framework 1 once constructed ( see . fig2 and 3 ). conduit 20 is disposed in receiving cavity 11 with busbars 21 embedded in opposing facing insulation sections 22 , all extending in a longitudinal direction noted by numeral 6 and accessible along a longitudinal side 14 through opening 7 . receiving space 11 , accessible from open side 14 , exhibits a relatively rectangular or square cross - section , an is preferably formed with a enlarged area or bulge on the side opposite open side 14 . the lateral walls 11 . 1 perpendicular to open side 14 are configured as partial receiving cavities 11 . 4 for the two insulation sections 22 , whereby each lateral wall section 11 . 1 forms a base strut with a lateral restriction to the partial cavity provided thereon at right inward angles by limiting struts 11 . 2 , 11 . 3 . insulation sections 22 are positioned in the partial receivers , e . g ., inserted during the manufacturing process or subsequently , and exhibit an essentially rectangular cross - section . insulation 22 includes longitudinally - extending grooves into which barlike busbars 21 , shown having rectangular cross - sections , are introduced on the insulation &# 39 ; s inner facing sides . busbars 21 are thereby situated deep in longitudinal grooves 22 . 1 of insulation section 22 such that the lateral groove walls protrude far enough outward so as to ensure protection is provided against any accidental further contact with the busbars 21 . the longitudinal opening 7 disposed at first interior section side 11 , corresponding to open side 7 of section 4 , is provided with a grounding rail 23 in the form of a copper band on at least one side of the facing edges so as to provide a simple grounding terminal . frame section 10 is advantageously utilized as at least one vertical frame leg 32 of framework 1 with suitable corner connections by simply screwing or otherwise connecting leg 32 to a top and bottom frame formed by horizontal frame legs 10 &# 39 ;, 10 ″ at the width and depth as shown in fig2 and 3 . in frame section 10 shown in fig2 and 3 with conduit 20 , longitudinally extending t - grooves 16 are provided for affixing mountings or transverse struts at the two inner section sides 14 , 15 disposed at a right angle to one another and abutting receiving cavity 11 . for example , screw strips with a row of drill holes can be disposed in t - grooves 16 , 17 to provide for mounting . alternatively , frame section 10 can also be provided with rows of mounting holes similar to the rows of mounting holes provided in the two horizontal frame legs 10 &# 39 ;, 10 ″. the electrical devices fitted as desired into the framework , such as , for example , control units or servers , can be easily connected to adapter 40 shown in fig5 . adaptor 40 is fitted to be inserted into conduit 20 to provide electrical contact with busbar 21 . block - shaped adapter 40 is shown configured for introduction to conduit 20 in longitudinal orientation to the opening 7 of receiving cavity 11 and thereafter comes into contact with busbar 21 upon a 90 ° rotation . contacts 41 of adapter 40 can also be spring - mounted , for example , in order to generate the necessary contacting force with busbars 21 . longitudinal grooves 22 . 1 of the two - sided partial insulation sections 22 are situated in a plane parallel to the open side 14 . a pair of busbars 21 may provide a conventional direct voltage and another pair of busbars 21 may provide an alternating voltage or another direct voltage or serve as a line for data transmission . the connection of conduit 20 to a supply voltage can likewise transpire via a suitable adapter 40 or from the lower or upper face side . when joining frameworks together , adapters 40 in adjacent frame sections 10 can be connected in series so that only one connection to a voltage supply is necessary . if desired , alternatively or additionally , at least one horizontal frame leg 10 ′, 10 ″ of a frame section 10 can be configured with a conduit 20 . a conduit 20 can also be provided in the manner described on a lateral wall of a switchgear cabinet via a canted frame leg . since at least the vertical frame leg is disposed with a free space 13 at its exterior 3 , accessories 80 such as hinges or locking elements or side panels can be readily connected thereto , with their canting extending into free space 13 and with their inner side tightly abutting sealing edging 12 . fig6 shows a table arrangement or system 30 having tables 31 with vertical frame legs configured as supporting pillars extending to the height of the table tops or even higher and which can be provided with additional storage shelf racks . the vertical frame legs are preferably arranged at the ends of the table tops , are configured at least partially from frame sections with conduits 20 accessible from the interior 2 and are preferably configured to be essentially flat at least on their inward opposing facing sides . in addition to the longitudinally extending access openings 7 to the respective conduits 20 , a number of rows of fixing cavities are preferably arranged in longitudinal direction for attaching horizontal frame legs , e . g ., via hooks and / or bolted connections . in addition , horizontal frame legs can also be outfitted as frame sections with conduits 20 of the type specified above . an electrical coupling between conduits 20 of the vertical and the horizontal frame legs can be made by means of adapted coupling elements provided with contacting means on their sides situated at right angles to one another . it will suffice to make the connection to a supply at only one vertical or horizontal frame leg from which the current can then be transmitted on to other frame legs by means of coupling elements 40 . correspondingly encompassed in particular by the terms framework , rack , switchgear cabinet , table 31 and table arrangement 30 cited in the present embodiments are also such arrangements or combinations thereof for information technology ( it ) including rack superstructures or shelves for monitors or server cabinets or the like . although the invention has been described in conjunction with specific embodiments thereof , it is evident that many alternatives , modifications and variations will be apparent to those skilled in the art . accordingly , it is intended to embrace all such alternatives , modifications and variations that fall within the spirit and broad scope of the appended claims .
