Abstract

An adapter and interface permits a standard mortise lock to drive top and bottom latch mechanisms of a multi-point lock system. An actuator permits in situ adjustment of the top and bottom vertical latch projections of adjusting these projections while the door is hung in the door frame. An installation tool assists in the installation of the vertical rods in a door. A connector and carrier secures the vertical rods to the actuator and permits verification of retention of the rods in a multi-point latching system. A latch dogging indicator allows for end-user adjustment between a single-point lock and a multi-point lock system when desired. These different aspects may be employed in combination or separately with other locking systems.

First claim

Thus, having described the invention, what is claimed is:

1. An adapter for enabling a mortise lock with a mid-point latch to actuate a vertical rod door latch, the mortise lock being mountable between outer panels of a door and having an opening for a handle to actuate a mid-point latch extending therefrom at a door edge from an extended locked position to a retracted open position, the adapter comprising:
a housing having an actuator for a vertical rod door latch, the actuator moving a vertical rod door latch from an extended locked position to a retracted open position; and
an adapter hub rotatable with respect to the housing, the adapter hub having a handle shaft opening for and rotatable by the mortise lock handle shaft, the adapter hub handle shaft opening being positionable in alignment with the mortise lock handle shaft opening between the mortise lock and an inner surface of a door outer panel;
the adapter hub being operatively connected to the vertical rod door latch actuator such that upon rotation of the adapter hub by the handle shaft the vertical rod door latch moves from an extended locked position to a retracted open position while the handle shaft simultaneously rotates the mortise lock handle shaft opening and hub to move the mid-point latch from an extended locked position to a retracted open position.

2. The adapter of claim 1 further including an arm between the adapter hub and the vertical rod door latch actuator, the arm being moveable with operation of the adapter hub such that upon rotation of the adapter hub by the handle shaft, the arm causes the vertical rod door latch to move from an extended locked position to a retracted open position.

3. The adapter of claim 1 wherein the housing further includes a pair of sleeves, the sleeves being positionable on both sides of the mortise lock, between the mortise lock and the inner surfaces of the door outer panels, and including an adapter hub with a handle shaft opening on each housing sleeve, each adapter hub having an arm extending therefrom and engageable with the actuator mechanism to cause the vertical rod door latch to move from an extended locked position to a retracted open position.

4. A method for enabling a mortise lock with a mid-point latch to actuate a vertical rod door latch in a door having outer panels, the method comprising:
providing a mortise lock having an opening for a shaft of a handle to actuate a mid-point latch extending therefrom at a door edge from an extended locked position to a retracted open position;
providing an adapter having a housing with an actuator for a vertical rod door latch, the actuator adapted to move a vertical rod door latch from an extended locked position to a retracted open position; an adapter hub rotatable with respect to the housing, the adapter hub having a handle shaft opening for and rotatable by the mortise lock handle shaft, the adapter hub handle shaft opening being positionable in alignment with the mortise lock handle shaft opening between the mortise lock and an inner surface of a door outer panel, the adapter hub upon rotation by the handle shaft causing the vertical rod door latch to move from the extended locked position to the retracted open position while the handle shaft simultaneously rotates the mortise lock handle shaft opening and hub to move the mid-point latch from an extended locked position to a retracted open position;
inserting the adapter into a door edge between door outer panels and operatively connecting the adapter to the vertical rod door latch in the door;
inserting the mortise lock into the adapter in the door edge and aligning the mortise lock handle shaft opening with the adapter hub handle shaft opening; and
using a handle shaft inserted through an opening in the outer door panel and extended into both the adapter hub handle shaft opening and the mortise lock handle shaft opening, rotating the handle shaft to simultaneously cause the vertical rod door latch to move from an extended locked position to a retracted open position and move the mid-point latch from an extended locked position to a retracted open position.

5. The method of claim 4 wherein the adapter further includes an arm between the adapter hub and the vertical rod door latch actuator, the arm being moveable with operation of the adapter hub such that upon rotation of the adapter hub by the handle shaft, the arm causes the vertical rod door latch to move from an extended locked position to a retracted open position.

6. The method of claim 4 wherein the housing further includes a pair of sleeves, the sleeves being positionable on both sides of the mortise lock, between the mortise lock and the inner surfaces of the door outer panels, and including an adapter hub with a handle shaft opening on each housing sleeve, each adapter hub having an arm extending therefrom and engageable with the actuator mechanism to cause the vertical rod door latch to move from an extended locked position to a retracted open position.

7. A tool for installing a rod in a door having a concealed vertical rod door latch actuator therein, the rod having a first end for attachment to a receiver coupled to the actuator and having an opening for receiving the rod first end and a second end for driving a latch, the tool comprising a sleeve positionable around the rod and moveable along a longitudinal axis of the rod to extend beyond the rod first end, the sleeve having a first end configured for mating with the receiver, the rod being moveable within and with respect to the sleeve such that upon mating of the sleeve with the receiver, the rod may be extended beyond the sleeve first end and into the receiver for attachment thereto.

8. The tool of claim 7 wherein the sleeve first end has a protrusion extending therefrom configured to mate with an outer surface of the receiver.

9. The tool of claim 8 wherein the sleeve protrusion is adapted to extend around at least a portion of the outer surface of the receiver.

10. The tool of claim 7 wherein the rod further includes a stop for preventing movement of the sleeve in the direction of the rod second end.

11. The tool of claim 10 wherein the sleeve second end includes a slot for receiving the stop.

12. The tool of claim 7 wherein one or both of the sleeve and rod are comprised of photoluminescent material.

13. The tool of claim 7 wherein the rod has a non-circular cross-section and the sleeve has a correspondingly-shaped cross-section for at least a portion of its length for preventing rotation of the sleeve about the longitudinal axis of the rod.

14. The tool of claim 7 wherein the rod has a length sufficient to reach substantially from a top or bottom of the door to the concealed actuator receiver within the door.

15. A method for installing a rod in a door having a concealed vertical rod door latch actuator, the method comprising:
providing a door having a concealed vertical rod door latch actuator in an interior portion of the door, the vertical rod door latch actuator including a receiver having an opening for receiving a vertical rod;
providing a rod having a first end for attachment to the actuator receiver and a second end for driving a latch;
providing a tool for installing the rod in the door, the tool coupled to the vertical rod and comprising a sleeve moveable along a longitudinal axis of the rod and extendable beyond the rod first end, the sleeve having a first end configured for mating with the receiver, the rod being moveable within and with respect to the sleeve;
extending the sleeve beyond the first end of the rod;
inserting the rod first end and sleeve into the d
