Abstract
An exit device for a door includes an actuator, a first rod, a second rod, a transom latch, and a side latch having a hook latch head. The side latch may be a mortise latch which may include a plurality of grooves for alignment during installation. When installed in an associated door, the exit device may withstand multiple impacts from windborne objects or pressures induced by high winds.
Claims18
An exit device, comprising:
- an actuator including a lever, a first cam, and a second cam, wherein the first cam is configured to convert an actuation force applied to the lever to a first force in a first direction, and wherein the second cam is configured to convert the actuation force applied to the lever to a second force in a second direction;
- a first rod coupled to the first cam configured to transmit the first force in the first direction;
- a second rod coupled to the second cam configured to transmits the second force in the second direction;
- a transom latch including a latch head configured to move between an engaged position and a disengaged position coupled to the first rod, wherein, when the first rod transmits the first force in the first direction, the latch head is moved from the engaged position to the disengaged position;
- and
- a side latch including a hook latch head configured to move between a hook engaged position and a hook disengaged position coupled to the second rod, wherein, when the second rod transmits the second force in the second direction, the hook latch head is moved from the hook engaged position to the hook disengaged position, wherein the hook latch head rotates between the hook engaged position and the hook disengaged position, and wherein the hook latch head is coupled to the second rod by a rack and pinion interface.

An actuator for an exit device, comprising:
- a chassis;
- a lever rotatably mounted to the chassis by a hinge portion and including a cam engagement portion;
- a first cam coupled to a first rod holder, wherein the first rod holder is slidably disposed in the chassis which allows movement of the first rod holder along a first axis;
- and
- a second cam coupled to a second rod holder, wherein the second rod holder is slidably disposed in the chassis which allows movement of the second rod holder along a second axis;
- wherein the cam engagement portion engages the first cam and the second cam concurrently when the lever is rotated about the hinge portion by a user to move the first rod holder in a first direction along the first axis and the second rod holder in a second direction along the second axis, wherein the first rod holder includes a deadlatching catch to directly inhibit movement of the first rod holder in the first direction without rotation of the lever by a user.
