Slide bolt assembly for an astragal

An astragal assembly for disposition on a free end of a semi-active door in a double-door set, said astragal assembly comprising:

• an astragal presenting a wall;
• a slide bolt assembly including an elongated base having an end for a bolt to extend therefrom, said elongated base extending along an axis and slideably engaged with said wall of said astragal for sliding along said astragal generally parallel with said axis between a retracted position and an extended position;
• said elongated base defining a threaded hole extending generally perpendicular to said axis;
• a screw lock presenting a central portion and a rim portion extending from and peripherally surrounding said central portion, said screw lock threadingly engaging said threaded hole of said elongated base and being rotatable between an unlocked position and a locked position for locking said elongated base within said astragal;
• and
• a nipple protruding from said central portion of said screw lock in a common direction with said rim portion and extending further from said central portion than said rim portion for piercing said wall of said astragal in said locked position to prevent sliding of said slide bolt assembly within said astragal;
• wherein said rim portion presents a contact surface frictionally engaging said wall of said astragal simultaneously with said nipple piercing said wall of said astragal in said locked position.

A slide bolt assembly for sliding between a retracted position and an extended position within an astragal disposed at a free end of a semi-active door in a double-door set to releasably lock the semi-active door in a closed position, said slide bolt assembly comprising:

• an elongated base having an end for a bolt to extend therefrom, said elongated base extending along an axis for slideably engaging the astragal generally parallel with said axis between the retracted position and the extended position;
• said elongated base defining a threaded hole extending generally perpendicular to said axis;
• a screw lock presenting a central portion and a rim portion extending from and peripherally surrounding said central portion, said screw lock threadingly engaging said threaded hole of said elongated base for rotation between an unlocked position and a locked position to lock said elongated base within the astragal;
• and
• a nipple protruding from said central portion of said screw lock in a common direction with said rim portion and extending from said central portion further than said rim portion, said nipple being configured to pierce a wall of the astragal when said screw lock is rotated to the locked position to prevent sliding of said slide bolt assembly within said astragal;
• wherein said rim portion presents a contact surface configured to frictionally engage the wall of the astragal simultaneously with said nipple piercing the wall of the astragal in said locked position.
