Abstract
Metal clad switchgear apparatus is taught which includes a skeletal arrangement formed from using "five-fold" channel members with eight unitary corner members. Four type "A" corner members are utilized and four type "B" corner members are utilized. The "A" and "B" corner members are formed from utilizing three identical gusset members in any one of two alternate dispositions. The formed corners are self-aligning and self-jigging relative to the channels which interlink them.
Claims13
A corner support, comprising:
- three channel members each of which has an opening in the periphery thereof, and each of which is disposed generally perpendicular to the other two at an apex region;
- and
- three generally identical gusset members each of which has two resilient protruding portions thereon which are oriented at ninety degrees relative to each other, each said opening having one resilient portion on one of said gusset members extending therethrough only one of said openings in combination with only one resilient portion of another of said gusset members in said apex region to bear between internal surface regions of said channel member in a state of compression to align the remainder of each gusset member in a disposition which places all three gusset members in a corner arrangement in said apex region.
Switchgear, comprising:
- circuit interrupting means for controlling an electrical circuit;
- skeleton support means disposed around said circuit interrupter means for assisting in isolating said circuit interrupter means from a predetermined region, said skeleton support means including three channel members each of which has an opening in the periphery thereof, and each of which is disposed generally perpendicular to the other two channel members at an apex region;
- and
- three generally identical gusset members each of which has two resilient protruding portions thereon which are oriented at ninety degrees relative to each other, each said opening having one resilient portion on one of said gusset members extending therethrough in combination with only one resilient portion of another of said gusset members in said apex region to bear between internal surface regions of said channel member in a state of compression to align the remainder of each gusset member in a disposition which places all three gusset members in a corner arrangement in said apex region.
