Claim 0:
1. A wirelessly-controlled jamb-mounted access control system, the system comprising:
a housing configured to be disposed in a door jamb;
a lock body at least partially inside the housing and rotatable about a first axis between locked and unlocked positions, wherein the first axis extends parallel to the door jamb, and wherein the lock body includes inner and outer sidewalls that define a latch cavity configured to receive a latch tongue of a swinging door, wherein the inner sidewall extends away from the first axis by a first distance, and wherein the outer sidewall extends away from the first axis by a different second distance;
an arm inside the housing and rotatable between first and second positions, wherein in the first position, the arm engages the lock body and inhibits rotation of the lock body about the first axis, and in the second position, the arm is disengaged from the lock body, wherein the arm rotates about a second axis extending orthogonally to the first axis;
an actuator configured to control release of the lock body from the locked position in response to a control signal; and
a linkage system coupling a shaft of the actuator to the arm, wherein rotation of the shaft is configured to cause a corresponding change in position of the arm;
wherein the actuator is a rotary actuator configured to rotate the shaft about a third axis, the third axis extending orthogonally to the first axis and the second axis; and
wherein the linkage system includes:
a first link member engageable with the arm;
a second link member movably coupled to the first link member; and
a cam member extending radially outward from the shaft and movably coupled to the second link member, the cam member configured to translate the second link member and the first link member along a fourth axis in response to the rotation of the shaft, the fourth axis extending parallel to and laterally offset from the first axis.
