Combined vehicle vent and escape hatch having a frame bounding a roof opening, a cover hingedly connected to opposite sides of the frame by hinge brackets for limited venting movement relative to one or more of the sides, one of the brackets being separable into cover and frame parts and normally prevented from separating by a cammable release rod engaging the cover part and a frame-backed movable stop plate backing the rod, and an emergency button instanding from the cover and when pushed operative to project the cover from all of said sides to full venting position and separate the parts of the separable bracket for enabling the cover, as an escape hatch, to be swung about the opposite bracket to open position. For extending the service life of the combined vent and hatch, an inner panel of the cover is backed by a rigid metal backup plate on which, for relieving the panel of stress, are hung the operating parts attached to the cover.
A vehicle vent and escape hatch assembly, comprising a frame bounding an opening in a vehicle, a cover for opening and closing said opening, hinges connecting said cover to opposite sides of said frame for limited movement to venting position relative to said frame sides, one of said hinges being separarable into frame and cover parts, rectilinearly shiftable rod means normally engaging said separable hinge for preventing separation thereof in closed and venting positions of said cover, and means operative in said venting position for rectilinearly shifting said rod means to disengage said separable hinge therefrom and enable said cover to be swung to open position about the other hinge.
A vehicle vent and escape hatch assembly, comprising a frame bounding a vehicle opening, a cover for opening and closing said opening, said cover being connected by hinges to opposite sides of said frame and normally partly openable to venting position relative to certain of said sides, one of said hinges being separable for enabling said cover to be swung from venting to open position about the other hinge, and rectilinearly shiftable rod means normally engaging said separable hinge for preventing separation of said one hinge when said cover is in closed and venting positions, said rod means in said venting position being rectilinearly shiftable for disengaging said rod means from said separable hinge and enabling said cover to be swung to open position about the other hinge.
A vehicle vent and escape hatch assembly, comprising a frame bounding a vehicle opening, a cover for opening and closing said opening, said cover being hinged to opposite sides of said frame by hinges, one of said hinges being separable for enabling said cover to be swung to open position about the other hinge, said cover being partly openable to venting position relative to certain of said sides, rectilinearly shiftable rod means normally engaging said separable hinge for holding said separable hinge against separation when said cover is in closed and venting positions, and push button means instanding from said cover and operatively connected to said rod means, said push button means being operative when pushed for raising said cover from said frame to venting position and by rectilinearly shifting said rod means disengaging said separable hinge from said rod means and enabling said cover to be swung open.
