Abstract

An improved astragal and flush bolt assembly to be secured to a relatively stationary member such as a door jamb or to the edge of an inactive door of a pair of double doors or the like. The astragal assembly includes a flat metal body mounted on the edge of the stationary member and a metal stop member secured to the body along one edge thereof. The flat body includes first and second spaced apart legs extending outwardly from the stationary member with the flat body and legs defining a channel to receive and retain a door latch bolt from the active door. The stop member prevents movement of the door in a first direction and when the latch bolt is engaged in the channel, the channel and latch bolt prevent the door from moving in the opposite direction. A pair of flush bolts are slidably mounted in the channel, one adjacent each end thereof, so that when the astragal assembly is utilized with double doors, the flush bolts are moved to engage the header and sill, respectively, to hold the inactive door stationary. The astragal body is secured to the stop member by a thermal barrier or thermal break structure to provide thermal insulation between the inside and the outside of the doors. The stop member also includes a weather strip to form a tight seal against the active door and when metal doors or metal covered doors are used, the weather strip may include a magnetic member to form a tight seal against the active door.

Dependent claims

In an astragal assembly to be secured to a relatively stationary member such as a door jamb, or the edge of an inactive door or the like, said astragal including a generally flat elongated body to be mounted on said stationary member and a stop member secured to said body along one edge thereof to limit swinging movement of a relatively active door member, the improvement comprising:

first and second spaced apart elongated legs formed integrally with said flat body and extending outwardly therefrom away from said relatively stationary member, the flat body and legs together defining an outwardly opening channel to receive and retain a slidable flush bolt;
said slidable flush bolt being a thin, flat elongated member having opposed sides and an elongated slot therethrough;
resilient means in said channel to engage each side of said flush bolt to slide with said flush bolt and to frictionally retain said flush bolt in said channel;
means for fastening said channel to said stationary member;
said fastening means extending through said slot for limiting the sliding movement of said flush bolt in said channel;
and
a thermally insulating material interposed between said stop member and said body, said stop member being secured to one edge of said thermally insulating material and said second leg being connected to the other edge of said thermally insulating material so that said thermally insulating material forms a thermal barrier between the astragal body and the astragal stop member;
said stop member preventing swinging of said relatively movable door past the relatively stationary member in a first direction and said first leg of said channel cooperating with said door latch to prevent swinging movement of said relatively active member past said relatively stationary member in the opposite direction.

In an astragal assembly to be secured to a relatively inactive member such as a door jamb or the edge of an inactive door of a double door or the like, said astragal including a generally flat elongated base to be mounted on said inactive member and a stop member mounted transversely of said base and along one edge thereof to limit swinging movement of a relatively active door member, the improvement comprising:

first and second spaced apart elongated legs formed integrally with said base and extending outwardly therefrom away from said inactive member toward said active member when said active member is closed, the legs and base defining a channel to receive and retain a latch bolt from the active member;
each of said legs including an inwardly facing flange with the inwardly facing flange and said base defining a guide for a flush bolt;
and
at least one flush bolt slidably mounted in said guide at one end thereof;
said flush bolt having an elongated slot therethrough;
means extending through said slot for both fastening said channel to said inactive member and for limiting the sliding movement of said flush bolt;
and
a thermally insulating material interposed between said stop member and said body, said stop member being secured to one edge of said thermally insulating material and said second leg being connected to the other edge of said thermally insulating material so that said thermally insulating material forms a thermal barrier between the astragal body and the astragal stop member;
so that upon closing said inactive door and sliding the flush bolt, the flush bolt may engage a conventional keeper or the like to maintain said inactive door in a closed position and, said stop member prevents swinging movement of said active door past a closed position and further said first leg of said channel receiving a latch bolt from said active door member to prevent swinging of said active member toward an open position.
