Abstract
A device for securing bulkhead doors consists of a single length of rigid, angled metal bar stock that preferably extends across the full internal width of the doors. A pair of elastomeric bumpers located at each end of the bar make contact with the underside of the bulkhead doors or the side pillars on which the doors rest. The bar is braced against the doors by engagement with a retention bracket, which may be the existing bracket already associated with the bulkhead doors.
Claims9
In a bulkhead closure that includes a pair of doors having inside surfaces and outside surfaces and which is hinged to a pair of spaced-apart parallel side pillars so that the doors open out from closed positions to open positions:
- a. a rigid bar, the bar being longer than the distance between side pillars;
- b. contact means located at each end of the bar for engaging the pillars, each contact means having a separately adjustable extension from the bar;
- and
- c. bar-retention means including a retainer bracket mounted to the inside surface of at least one of the doors, the bar comprising slots for receiving the retainer bracket and being movable into engagement therewith so that a flat surface of the bar rests against a flat surface of the retainer bracket, and the bar extends generally perpendicular to the side pillars and bridges the pair of doors.

- a. a rigid bar, the bar being longer than the distance between side pillars;
- b. contact means located at each end of the bar for engaging the pillars, each contact means having a separately adjustable extension from the bar;
- and
- c. means for pivotally connecting the bar to one of the doors so that the bar can be pivoted to engage the contact means against the pillars when the doors are in their closed positions.
