ABSTRACT:
A device for opening, closing and latching a roof vent closure member for vehicles and including an upper latch member pivotally connected to the closure member, a lower latch member pivotally connected to the frame defining the opening in the roof, said upper and lower latch members being pivotally interconnected and a bar connected to said upper latch member in offset relation to its pivotal connection to the lower latch member for actuating the device. The pivotal connections of the latch members are arranged to provide a toggle or off center relationship in closed position of the closure member. The latch members and pivotal connections thereof are so arranged to permit the crossbar to be positioned below and outwardly of the frame defining the roof opening to provide headroom, non-obstructed vision, and aesthetic appearance. The device includes means for adjusting the positions of certain pivotal axes of said pivotal interconnections to adjust the latch members to roof or wall structures of different depth.
