Overhead locking device

A latch assembly, comprising:

• a housing assembly comprising an aperture;
• a roller seated in the aperture for movement between a first position and a second position;
• a latch bolt mounted to the housing assembly for axial movement along a longitudinal axis between a projected position and a depressed position relative to the housing assembly, wherein the latch bolt includes a ramped surface that engages the roller to urge the roller from the first position toward the second position as the latch bolt moves from the projected position toward the depressed position, and wherein engagement between the ramped surface and the roller prevents movement of the latch bolt from the projected position to the depressed position when the roller is in the first position, and wherein the roller permits movement of the latch bolt from the projected position to the depressed position when the roller is in the second position;
• and
• a locking sleeve movably mounted between an inner housing and an outer housing of the housing assembly;
• wherein the locking sleeve is configured to be driven between a locking position and an unlocking position via an actuator, wherein a blocking surface of the locking sleeve is aligned with the roller and engages the roller when the locking sleeve is in the locking position to prevent movement of the roller from the first position to the second position and thereby retain the latch bolt in the projected position, and wherein a recess of the locking sleeve is aligned with the roller when the locking sleeve is in the unlocking position to receive the roller and permit
• movement of the roller from the first position to the second position to thereby enable depression of the latch bolt;
• and
• wherein the locking sleeve is configured to be linearly driven between the locking position and the unlocking position via the actuator.
