Reinforced collapsible garage door assembly

DETAILED DESCRIPTION It has now been found that the foregoing and related objects can be readily attained in a reinforcement assembly for reinforcing a door of the overhead type having a plurality of horizontally extending panels pivotably connected along their top and bottom edges.
The reinforcement assembly has a plurality of elongated reinforcing members dimensioned and configured to be operatively mounted vertically on the inner surface of an associated door between the top edge and the bottom edge of each of the several door panels, and a plurality of cap members overlying the adjacent ends of the reinforcing members.
Pivot means pivotally connects the cap members to the adjacent ends of the reinforcing members and permits their relative pivotal movement in the direction away from the cap members for pivoting of the panels of the associated door as the door is moved between open and closed positions.
The configuration of the cap members and pivot means prevents pivoting of the ends of the reinforcing members in the direction of the cap members to prevent buckling of the associated door in its closed position under positive pressures applied externally thereto.
Disengageable lock means is engageable with the cap members and the ends of the reinforcing members at a point spaced from the pivot means to prevent pivoting of the ends of the reinforcing members away from the cap members to prevent buckling of the panels of the associated door in its closed position of under both positive and negative pressures applied thereto.
Preferably, the reinforcement assembly also includes top locking means having a header member attachable to the header of the door frame and a catch member on the upper end of the uppermost reinforcing member.
The catch member is engageable with the header member in the closed position of the door to prevent movement of the upper end of the reinforcement assembly, and is disengageable from the header member upon opening movement.
In one embodiment, the header member has a hook projection, and the catch member has a projecting portion in which the hook is engageable in the closed position of the door
