Exit device push force reducer

An exit device comprising:

• a push bar movable between an unactuated position and an actuated position;
• an arm operatively coupled to the push bar, wherein the arm is movable between a first arm position and a second arm position, and wherein movement of the push bar from the unactuated position to the actuated position moves the arm from the first arm position to the second arm position;
• a lever operatively coupled to the arm, wherein the lever is movable between a first lever position and a second lever position, and wherein movement of the arm from the first arm position to the second arm position moves the lever from the first lever position to the second lever position;
• a slide operatively coupled to the lever, wherein the slide is movable in a linear direction of movement between a first slide position and a second slide position, and wherein movement of the lever from the first lever position to the second lever position moves the slide from the first slide position to the second slide position;
• and
• one or more biasing members coupled to the slide and configured to bias the slide to the second slide position, thereby reducing a force to move the push bar from the unactuated position to the actuated position.

An exit device comprising:

• a push bar movable between an unactuated position and an actuated position;
• an arm operatively coupled to the push bar, wherein the arm is rotatable between a first arm position and a second arm position, and wherein movement of the push bar from the unactuated position to the actuated position rotates the arm from the first arm position to the second arm position;
• a lever operatively coupled to the arm, wherein the lever is rotatable between a first lever position and a second lever position, and wherein rotation of the arm from the first arm position to the second arm position rotates the lever from the first lever position to the second lever position;
• a slide operatively coupled to the lever, wherein the slide is movable in a linear direction of movement between a first slide position and a second slide position, and wherein rotation of the lever from the first lever position to the second lever position moves the slide from the first slide position to the second slide position,
• wherein the exit device is configured to be coupled to a door;
• a rod operatively coupled to a latch for securing the door, wherein the rod is operatively coupled to the slide, wherein the rod is movable between a first rod position and a second rod position, and wherein movement of the slide from the first slide position to the second slide position moves the rod from the first rod position to the second rod position,
• wherein the latch is movable between a latched position and an unlatched position, and wherein movement of the rod from the first rod position to the second rod position moves the latch from latched position to the unlatched position;
• and
• one or more springs coupled to the slide and configured to bias the slide to the second slide position, thereby reducing a force to move the push bar from the unactuated position to the actuated position.

An exit device comprising:

• a push bar movable between an unactuated position and an actuated position;
• a bolt operatively coupled to the push bar, wherein the bolt is movable between a bolt extended position and a bolt retracted position, and wherein movement of the push bar from the unactuated position to the actuated position moves the bolt from the bolt extended position to the bolt retracted position and wherein the bolt is configured to secure the exit device in the bolt extended position;
• an arm operatively coupled to the push bar, wherein the arm is movable between a first arm position and a second arm position, and wherein movement of the push bar from the unactuated position to the actuated position moves the arm from the first arm position to the second arm position;
• and
• one or more arm biasing members coupled to the arm and configured to bias the arm to the second arm position, thereby reducing a force to move the push bar from the unactuated position to the actuated position.

• an arm operatively coupled to the push bar, wherein the arm is movable between a first arm position and a second arm position, and wherein movement of the push bar from the unactuated position to the actuated position moves the arm from the first arm position to the second arm position;
• a slide plate operatively coupled to the arm, wherein the slide plate is movable in a linear direction of movement between a first slide plate position and a second slide plate position, and wherein movement of the arm from the first arm position to the second arm position moves the slide plate from the first slide plate position to the second slide plate position;
• and
• one or more slide plate biasing members coupled to the slide plate and configured to bias the slide plate to the second slide plate position, thereby reducing a force to move the push bar from the unactuated position to the actuated position.
