Invisible opening mechanism for a candelabra access door

摘要

The mechanism (1) has a cross bar fixed on an inner face of a pillar (4). A slide (6) is displaced inside a housing of the cross bar. A yoke (7) is fixed on an inner face of an inspection door (2) and articulated at a free end of the slide by an axle (8). An active attaching unit (9) maintains the door in raised opened position. A locking unit (10) i.e. quarter turn bolt, locks the door in closed position. The yoke has a bolt to maintain the door in continuity of an outer wall of the pillar even if the locking unit is opened or deteriorated.
