Hardware for a hinged light panel
A securing mechanism for a hinged sidelight panel. The securing mechanism includes a center latch bolt for latching the hinged sidelight panel and remote locking mechanisms for locking the hinged sidelight panel. A single lever handle is used to selectively retract the remote locking mechanisms and the latch bolt. At a first orientation of the handle, both the remote locking mechanisms and the latch bolt are engaged. At a second orientation of the handle, the latch bolt remains engaged, but the remote locking mechanisms retracted. At a third orientation, both the remote locking mechanisms and the latch bolt are disengaged. The orientation of the handle informs an observer whether the locks are engaged. In one embodiment, the full rotation is about 90°, enabling the use of longer lever handles without interference from door frames.
1. A hinged door system for closing an opening in a structure, the system comprising:
a frame defining a primary door opening and a sidelight opening adjacent the primary door opening;
a first primary hinged panel operably disposed in the primary door opening, and a secondary hinged panel operably disposed in the sidelight opening;
a multi-point latching system on the secondary hinged panel, the multi-point latching system comprising:
a center cassette having an operating mechanism and a selectively retractable latch bolt operable with the operating mechanism;
at least one remote latch mechanism spaced apart from the center cassette, the at least one remote latch mechanism including a selectively operable latch bolt;
a coupler linking the at least one remote latch mechanism with the operating mechanism of the center cassette; and
a rotatable lever handle operably coupled with the operating mechanism of the center cassette such that when the handle is positioned in a first position, the latch bolt of the center cassette and the latch bolt of the at least one remote latch mechanism are extended to latch the secondary hinged panel in place in the sidelight opening, when the handle is rotated to a second position in a single direction of rotation, the latch bolt of the at least one remote latch mechanism is retracted and the latch bolt of the center cassette remains extended, and when the handle is rotated to a third position in the single direction of rotation, both the latch bolts of the center cassette and the at least one remote latch mechanism are retracted to enable the secondary panel to be opened.
2. The hinged door system of claim 1 , wherein the second position of the handle is a first angular distance from the first position, and the third position is a second angular distance from the first position, the second angular distance being greater than the first angular distance.
3. The hinged door system of claim 2 , wherein the first angular distance is 70 degrees.
4. The hinged door system of claim 2 , wherein the second angular distance is 90 degrees.
5. The hinged door system of claim 1 , wherein the multi-point latching system comprises two remote latch mechanisms.
6. The hinged door system of claim 5 , wherein the center cassette and the two remote latching mechanisms are disposed along a side margin of the secondary hinged panel opposite a pair of hinges disposed along an opposing side margin of the secondary hinged panel.
7. The hinged door system of claim 6 , wherein one of the remote latching mechanisms is disposed vertically above the center cassette and the other of the remote latching mechanism is disposed vertically below the center cassette.
8. The hinged door system of claim 1 , wherein the latch bolt of the center cassette is spring-loaded.
9. A multi-point latching system comprising:
a center cassette having an operating mechanism and a selectively retractable latch bolt operable with the operating mechanism;
at least one remote latch mechanism spaced apart from the center cassette, the at least one remote latch mechanism including a selectively operable latch bolt;
a coupler linking the at least one remote latch mechanism with the operating mechanism of the center cassette; and
a rotatable lever handle operably coupled with the operating mechanism of the center cassette such that when the handle is positioned in a first position, the latch bolt of the center cassette and the latch bolt of the at least one remote latch mechanism are extended to latch the secondary hinged panel in place in the sidelight opening, when the handle is rotated to a second position in a single direction of rotation, the latch bolt of the at least one remote latch mechanism is retracted and the latch bolt of the center cassette remains extended, and when the handle is rotated to a third position in the single direction of rotation, both the latch bolts of the center cassette and the at least one remote latch mechanism are retracted to enable the secondary panel to be opened.
10. The multi-point latching system of claim 9 , wherein the second position of the handle is a first angular distance from the first position, and the third position is a second angular distance from the first position, the second angular distance being greater than the first angular distance.
11. The multi-point latching system of claim 10 , wherein the first angular distance is 70 degrees.
12. The multi-point latching system of claim 10 wherein the second angular distance is 90 degrees.
13. The multi-point latching system of claim 9 , wherein the multi-point latching system comprises two remote latch mechanisms.
14. The multi-point latching system of claim 13 , wherein the center cassette and the two remote latching mechanisms are disposed along a side margin of the secondary hinged panel opposite a pair of hinges disposed along an opposing side margin of the secondary hinged panel.
15. The multi-point latching system of claim 14 , wherein one of the remote latching mechanisms is disposed vertically above the center cassette and the other of the remote latching mechanism is disposed vertically below the center cassette.
16. The multi-point latching system of claim 9 , wherein the latch bolt of the center cassette is spring-loaded.
