Abstract:
1. A support rail and extension rail assembly for an electrical switching apparatus housing assembly, said electrical switching apparatus housing assembly defining an enclosed space and having a right sidewall and a left sidewall, said support rail and extension rail assembly comprising: a first support rail assembly structured to be coupled to the interior surface of said right sidewall, said first support rail assembly having a base plate with a first, exterior surface and a second, interior surface; said first support rail assembly base plate interior surface includes a extension rail pivotal mounting, said first support rail assembly extension rail pivotal mounting structured to pivotally support an extension rail; said first support rail assembly base plate interior surface includes a positioning device structured to maintain a first extension rail in a second position; a first extension rail having an elongated body with a first end, a medial portion, a second end, and an upper rail surface, said first extension rail body having an elongated slot therein, said slot having a first medial end and a second distal end, said slot distal end being closer to said body second end than said body medial portion; said first extension rail pivotally coupled to said first support rail assembly extension rail pivotal mounting with said first support rail assembly extension rail pivotal mounting extending through said first extension rail elongated slot; wherein said first extension rail moves between a first position, an intermediate position and a second position; wherein when said first extension rail is in said first position, said first extension rail extends generally vertically with said first support rail assembly extension rail pivotal mounting disposed adjacent to said first medial end, when said first extension rail is in said intermediate position, said first extension rail extends generally vertically with said first support rail assembly extension rail pivotal mounting disposed adjacent to said slot distal end, and when said first extension rail is in said second position, said first extension rail extends generally horizontally with said first support rail assembly extension rail pivotal mounting disposed adjacent to said slot distal end; a second support rail assembly structured to be coupled to the interior surface of said left sidewall, said second support rail assembly having a base plate with a first, exterior surface and a second interior surface; said second support rail assembly base plate interior surface includes a extension rail pivotal mounting, said second support rail assembly extension rail pivotal mounting structured to pivotally support an extension rail; said second support rail assembly base plate interior surface includes a positioning device structured to maintain a second extension rail in second position; a second extension rail having an elongated body with a first end, a medial portion, a second end, and an upper rail surface, said second extension rail body having an elongated slot therein, said slot having a first medial end and a second distal end, said slot distal end being closer to said body second end than said body medial portion; said second extension rail pivotally coupled to said second support rail assembly extension rail pivotal mounting with said second support rail assembly extension rail pivotal mounting extending through said second extension rail elongated slot; wherein said second extension rail moves between a first position, an intermediate position and a second position; and wherein when said second extension rail is in said first position, said second extension rail extends generally vertically with said second support rail assembly extension rail pivotal mounting disposed adjacent to said first medial end, when said second extension rail is in said intermediate position, said second extension rail extends generally vertically with said second support rail assembly extension rail pivotal mounting disposed adjacent to said slot distal end, and when said second extension rail is in said second position, said second extension rail extends generally horizontally with said second support rail assembly extension rail pivotal mounting disposed adjacent to said slot distal end.
