Patent ID: 8061678

Claim:
A lockable articulating arm, including: a top portion and a bottom portion, each of which includes: a positive spring-force locking mechanism including: a first actuator coupled to a first flange via a first spring mechanism, and to a second flange by a first pivot pin; and a second actuator coupled to the second flange via a second spring mechanism, and to the first flange by a second pivot pin; wherein the flanges are coupled to a shank, which is further coupled to a handle; wherein each actuator is coupled to a respective pin; and a bell crank, coupled to a first pin on the first actuator, that extends a sliding lock which locks the articulating arm relative to a gantry when the handle is in the locked position; and a second bell crank, coupled to a second pin on the second actuator, that causes at least one locking pin to be extended to lock the articulating arm relative to a detector head when the handle is in the locked position; wherein the second bell crank actuates a shaft that extends a sliding pin linkage that urges a pair of locking pins in a distal portion thereof into a locked position, thereby locking the articulating arm relative to the detector head.
