Abstract
A door retainer mechanism on a padmounted switchgear cabinet includes a pair of elongated links coupled between an access door and housing of the cabinet. The links are pivotally connected respectively to the access door and housing and also pivotally connected to one another. The links are pivotable relative to each other between folded and unfolded conditions with respect to one another as the access door is moved between closed and opened positions relative to the cabinet housing. The links are operable automatically to latch with one another in the unfolded condition upon the access door reaching the opened position after being moved by a worker from the closed position relative to the cabinet housing. The links of the door retainer mechanism, once they have reached the unfolded condition and become latched with one another, function to retain the access door in the opened position and prevent the access door from returning to the closed position. The door retainer mechanism only allows the access door to return to the closed position after the links have been unlatched manually from one another by the worker and allowed to return to the folded condition with respect to one another. The door retainer mechanism also includes first and second stop elements mounted to a respective one of the first and second links and engageable with the respective other thereof so as to prevent the links from over-shooting the respective folded and unfolded conditions.
