Abstract: A system for securing a cam of a locking mechanism to a rotatable shaft, which comprises a cam for actuating a locking mechanism and a clutch that includes, in part, a sleeve body having a distal end affixed to a face of the cam and a sleeve bore having a tapered sleeve journal and a sleeve screw portion with internal threads opposite the sleeve journal. The clutch also includes a collet that is installed within the sleeve bore and which has a collet nut extending outwardly from a proximal end of the sleeve bore, a collet bore, and an outer surface having an axially-split and tapered collet journal abutting the sleeve journal and a collet screw portion with external threads engaged with the sleeve screw portion. The system further includes a rotatable shaft that is secured within the collet bore with a break-away torque that is proportional to an assembly torque applied to the collet nut. After assembly of the clutch to both the cam and the rotatable shaft, a drive torque applied to the shaft which is less than the break-away torque causes the cam to rotate with the shaft, while a drive torque that is greater than the break-away torque causes the shaft to spin within the collet bore.

Abstract: A self-balancing locking mechanism for actuating a locking pin-bar assembly of a door. The mechanism includes a drive shaft having an axis of rotation mounted to the door, and a cam mounted to the drive shaft. The mechanism also includes one or more actuator plates, each having a proximal end with a radial slot formed therein and installed about the drive shaft, and a distal end coupled to a locking pin-bar assembly that is slidably supported adjacent a perimeter of the door. The mechanism further includes one or more linkage bars, each having a proximal end pivotably coupled to the cam at a radial distance from the axis of rotation, and a distal end pivotably coupled to a mid-span of the actuator plate. Rotation of the cam causes the linkage bar to drive the actuator plate along a radial axis and engage the locking pin-bar assembly with a side edge of a door frame, and simultaneously cause the radial slot of the actuator plate to bear on the drive shaft and balance any off-axis loads applied by the linkage bar to the actuator plate.

Rotation of the cam causes the linkage bar to drive the actuator plate along a radial axis and engage the locking pin-bar assembly with a side edge of a door frame, and simultaneously cause the radial slot of the actuator plate to bear on the drive shaft and balance any off-axis loads applied by the linkage bar to the actuator plate.
