Abstract

The present invention relates to a latching device for a slide rod system incorporated into a door. The latching device includes a keeper plate engaged to the slide rod, a positioning bracket engaged to a door, and a roller bracket having a roller adapted for engagement to the positioning bracket and the keeper plate. The slide rod and keeper plate are adapted for positioning within a slide channel. The roller bracket is adapted for engagement to a doorframe channel. The positioning bracket includes a slot which receives the roller whereupon the keeper plate is at least partially manipulated vertically to maneuver the keeper to the rear of the roller to accomplish latching of a door.

a second bracket adapted to be engaged to a door frame, said second bracket comprising a latch, said latch comprising a roller, said vertically extending door having a closed door position and an open door position, the roller oriented for positioning within the slot of the first bracket in said closed door position;

wherein the keeper moves in a direction along said longitudinal vertical axis to releasably engage the roller in said closed door position when the slide rod is in the first position and disengage the roller in said open door position when the slide rod is in the second position.

14. The latching device of claim 13, wherein said keeper extends outwardly in a direction substantially perpendicular to said slide rod.

15. A latching device comprising:

a first bracket adapted to be engaged to a vertically extending door within a door frame, said first bracket comprising a body portion and a positionable rod, said positionable rod defining a longitudinal vertical axis, said positionable rod moveable vertically with respect to said body portion along said longitudinal vertical axis between a first position and a second position, the positionable rod having a first portion and a second portion, the second portion being separated from said first portion along a length of the positionable rod, the first portion configured for operable engagement with a handle, said positionable rod comprising a keeper, said keeper fixedly engaged to the second portion; and

a second bracket adapted to be engaged to the door frame, said first bracket being moveable in a direction orthogonal with respect to said second bracket and said longitudinal vertical axis during rotation of said vertically extending door between a proximate position relative to said door frame and a nonproximate position relative to said door frame, the second bracket comprising an engagable portion comprising a latch comprising a roller;

wherein when said positionable rod is in the first position, said keeper is vertically disposed to engage the roller of said second bracket to retain at least a portion of said second bracket in said proximate position.

16. The latching device of claim 15, wherein said keeper comprises a flat surface.

17. The latching device of claim 16, wherein said keeper defines a plane oriented parallel to the longitudinal vertical axis of said positionable rod, said engagable portion of said second bracket passes through said plane as said first bracket is moved out of said proximate position.
