Pivoting and barrier locking operator system
First Claim
1. A system for moving a barrier between limit positions comprising:
- an operator motor assembly mounted proximate to the barrier, at least a portion of said operator motor assembly movable between a barrier operating position and a barrier locking position with said operator motor assembly blocking movement of the barrier; and
a bias assembly biasing said operator motor assembly in said barrier operating position and allowing said operator motor assembly to move toward said barrier locking position when either a predetermined force overcomes a biasing force of said bias assembly or when the barrier is moved to a closed limit position.

Abstract
A system for moving a barrier between limit positions, includes an operator motor assembly mounted proximate to the barrier, wherein at least a portion of the motor assembly is movable between an operating position and a locking position with the motor assembly blocking movement of the barrier. A bias assembly biases the motor assembly in the operating position and allows the motor assembly to move toward the locking position when either a predetermined force overcomes a biasing force or when the barrier is moved to a closed limit position or when forced entry is imposed on the barrier. The biasing force may be adjusted by moving posts on the motor assembly that are engaged by the bias assembly. A disengagement feature may also be provided that allows pivotable movement of the motor assembly even when in a locking position. And the pivoting motor assembly may be used as a secondary entrapment input to an operator controller.

24. A system for moving a barrier between limit positions, comprising:
-
a counterbalance system adapted to be connected to the barrier; an operator motor assembly mounted proximal the barrier, at least a portion of said operator motor assembly movable between an operating position and a locking position; a bias assembly coupled to said operator motor assembly and maintaining said operator motor assembly in said operating position, said operator motor assembly overcoming a bias force of said bias assembly when the barrier is proximal a closed limit position; and a disengagement mechanism selectively interposed between said counterbalance system and said operator motor assembly, wherein actuation of said disengagement mechanism from an engagement position to a disengagement position allows said bias force to move said operator motor assembly from said locking position even when the barrier is proximal the closed limit position. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
