Abstract:
1. In combination: a switchgear enclosure having a vertically disposed door opening formed in a wall thereof with the wall having an outer surface and with the door opening having an upper edge, a lower edge, a first side edge, and a second side edge; a plurality of first hinges; each of said first hinges including first and second parts pivotally joined together by a vertically disposed pivot pin; said plurality of first hinges having their first parts operatively secured to said wall, in a vertically spaced-apart manner, adjacent said first side edge of said door opening; a door having an upper end, a lower end, a first side end, a second side, an inner surface and an outer surface; said second parts of said first hinges being secured to said door at said first side thereof in a vertically spaced-apart manner whereby said door may be moved between a first closed position and a second open position with respect to the door opening; said door having a height and width greater than the height and width of said door opening so that said upper end, said lower end, said first side and said second side of said door, when in said closed position, are positioned adjacent said wall around said door opening; a plurality of second hinges; each of said second hinges having first and second parts pivotally joined together by a vertically disposed pivot pin; said first parts of said second hinges being operatively secured to said wall in a vertically spaced-apart manner laterally outwardly of said second side edge of said door opening; an elongated, vertically disposed angle member having first and second wall portions which are transversely disposed with respect to one another; said second parts of said second hinges being secured to said second wall portion of said angle member; a plurality of elongated, horizontally disposed door latches having inner and outer ends; said inner ends of said door latches being secured to said angle member in a vertically spaced-apart manner for movement therewith; at least one of said door latches having a handle associated therewith; each of said door latches having a latch pin opening formed therein outwardly of said inner end thereof; said angle member and said door latches being pivotally movable from a latched position to an unlatched position; an elongated vertically disposed door latch housing having upper and lower ends and including a channel-shaped portion having an outer wall having an upper end, a lower end, an inner side, an outer side, a first side wall, a second side wall, a top wall, a bottom wall, a first flange extending from said first side wall, and a second flange extending from said second side wall; said outer wall, first side wall, second side wall, top wall and bottom wall defining an interior compartment; said door latch housing being positioned at said outer side of said door and secured to said door laterally of said second side of said door by fasteners extending through said first and second flanges and into said door; a latch handle having a shaft extending therefrom; said latch handle being rotatably positioned at said outer side of said channel-shaped portion of said door latch housing so that said shaft extends therefrom into said interior compartment; said latch handle being selectively rotatably movable between latched and unlatched positions; a first elongated actuator rod, having first and second ends, movably positioned in said interior compartment; a second elongated actuator rod, having first and second ends, movably positioned in said interior compartment; said first end of said first actuator rod being operatively coupled to said shaft of said latch handle; said first actuator rod extending from said shaft of said latch handle towards said top wall of said channel-shaped portion of said door latch housing; said first end of said second actuator rod being operatively coupled to said shaft of said latch handle; said second actuator rod extending from said shaft of said latch handle towards said bottom wall of said door latch housing; the movement of said latch handle from its unlatched position to its latched position causing said first actuator rod to move upwardly and causing said second actuator rod to move downwardly; the movement of said latch handle from its latched position to its unlatched position causing said first actuator rod to move downwardly and causing said second actuator rod to move upwardly; a plurality of horizontally disposed first latch plate assemblies positioned in said interior compartment and secured to said channel-shaped portion of said door latch housing in a vertically spaced-apart manner above said shaft of said latch handle; each of said first latch plate assemblies having first and second openings formed therein; a plurality of horizontally disposed second latch plate assemblies positioned in said interior compartment and secured to said channel-shaped portion of said door latch housing in a vertically spaced-apart manner below said shaft of said latch handle; each of said second latch plate assemblies having first and second openings formed therein; said first actuator rod longitudinally movably extending through said first openings in said first latch plate assembly; said second actuator rod longitudinally movably extending through said first openings in said second latch plate assemblies; a plurality of first latch pin assemblies secured to said first actuator rod for movement therewith said first latch pin assemblies being positioned below said first latch plate assemblies; each of said first latch pin assemblies including a latch pin extending upwardly therefrom which is received by said second opening in the associated first latch plate assembly when said latch handle is moved from said unlatched position to said latched position; a plurality of second latch pin assemblies secured to said second actuator rod for movement therewith with said second latch pin assemblies being positioned above said second latch plate assemblies; each of said second latch pin assemblies including a latch pin extending downwardly therefrom which is received by said second opening in the associated second latch plate when said latch handle is moved from said unlatched position to said latched position; said channel-shaped portion of said door latch housing having a plurality of slots formed therein which receive said door latches therein when said angle member and said door latches are pivotally moved to said latched position; said latch pin openings in said door latches, when said angle member and said door latches are in said latched position, being vertically aligned with said second openings in said first and second latch plate assemblies, whereby said latch pins are received by said second openings in said latch plate assemblies when said latch handle is moved from its unlatched position to its latched position; said first wall of said angle member being in engagement with said door when said door is in said closed position and said angle member and said door latches are in said latched position.
