초록 ▼

A control system is provided to lock, unlock and/or unlatch a door's lock and/or latch mechanism(s) having a bolt(s) coupled to a shaft(s). In one embodiment, a clutch is coupled to the shaft for rotation therewith. The clutch includes a movable lever attached thereto with a bias that causes the lever to protrude axially from the clutch. A plate is mounted coaxially with the shaft for free rotation relative thereto. The plate is adjacent the clutch on a side thereof from which the lever protrudes. The plate includes a notch formed therein facing the clutch. The plate and clutch are biased toward one another so that the plate and lever contact one another as the bias between the plate and the clutch overcomes the bias of the lever. A remotely-activated motorized drive is coupled to the plate for rotating the plate relative to the shaft in a direction of rotation that allows the lever to engage the notch. As a result of such engagement, rotation of the plate is transferred to the clutch for rotating the shaft until rotational resistance is experienced by the shaft. The system can also momentarily maintain the door's latching mechanism in its "open" position so that the door can be pushed open.

[ What is claimed as new and desired to be secured by Letters Patent of the United States is:] [1.] A control system for at least one door mechanism having a bolt coupled to a shaft, said bolt being movable between a protruding position and a withdrawn position as controlled by the rotation of said shaft wherein said shaft can experience a rotational resistance at each of said protruding position and said withdrawn position, said control system comprising:a clutch coupled to said shaft for rotation therewith, said clutch including a movable lever attached thereto and having a bias that causes said lever to protrude axially from said clutch;a plate mounted coaxial with said shaft for free rotation relative thereto, said plate residing adjacent said clutch on a side thereof from which said lever protrudes, said plate including a notch formed therein facing said clutch, said plate and said clutch biased toward one another wherein said plate and said lever contact one another and the bias between said plate and said clutch overcomes the bias of said lever; anda motorized drive coupled to said plate for rotating said plate relative to said shaft in a direction of rotation that allows said lever to engage said notch so that rotation of said plate is transferred via said lever to said clutch for rotating said shaft until said rotational resistance is experienced, wherein said rotational resistance is transferred from said shaft through said clutch and said lever to said plate so that said plate and said clutch experience axial movement away from one another as the bias between said plate and said clutch is momentarily overcome wherein said plate again freely rotates about said shaft so that said notch disengages from said lever as said plate moves in said direction of rotation.
