Remote control door operating and coupling assembly
First Claim
1. An apparatus for opening and closing a door hinged to a door frame, said apparatus comprising:
- a first bracket for mounting on a support surface and being in a fixed position with respect to the door;
a door actuator assembly having a first end pivotally coupled to said first bracket and a second end, said actuator assembly further having an actuator rod extending from said second end of said actuator assembly and being movable between an extended position to close said door and a retracted position with respect to said door actuator assembly to open said door;
a second bracket for coupling to said door at a location spaced from said door frame, said actuator rod being slidably coupled to said second bracket; and
a coupling assembly comprising a detent coupled to said second bracket for selectively engaging a recess in said actuator rod capturing said actuator rod to open and close said door by actuating said actuator rod between said extended position and said retracted position, and said detent releasing said actuator rod to allow said actuator rod to slide with respect to said second bracket to allow said door to be opened manually without interference from said actuator assembly.

Abstract
An apparatus for opening and closing a door remotely includes a remote radio control, electrically operated strike plate, and a door opening assembly attached to the door. A double acting piston is attached to a fixture on the floor. An actuator rod coupling assembly allows the door to move freely in a normal manner when the apparatus is deactivated. The coupling assembly has a detent which will release the piston rod in case of a sudden excessive force on the door that would otherwise damage the apparatus. The piston is a double acting piston that includes pressure switches to deactivate the pump when the pressure exceeds a threshold to prevent damage to the assembly. The mechanism can use potable water as the hydraulic fluid to eliminate contamination and fire hazards. The electrical system uses 12 volt DC operating voltages to eliminate electric shock.

14. An automatic door operating assembly for opening and closing a door hinged to a door frame, said assembly comprising:
-
a first bracket for mounting on a support surface, and being in a fixed position with respect to said door;
a door actuator having a piston and a cylinder, said cylinder having a first end pivotally coupled to said first bracket and a second end spaced from said first end, an actuator rod having a first end coupled to said piston and a second end spaced from said second end of said cylinder;
a second bracket for coupling to said door;
a coupling assembly for coupling said actuator rod to said second bracket, said coupling assembly including a body coupled to said second bracket, said body having a hole defining a passage extending therethrough, said second end of said actuator rod extending through said hole and being slidable therein;
a spring biased detent coupled to said body, said detent being spring biased to an extended position for engaging in and capturing said actuator rod and being movable to a retracted position for releasing said actuator rod, said actuator rod movable between a retracted position to open said door and an extended position to close said door when said detent captures said actuator rod, and where said detent releases said actuator rod when a predetermined axial force is applied to said actuator rod. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A remote operated door operating assembly, for opening and closing a door hinged to a door frame, said assembly comprising:
-
a first bracket for mounting on a support surface, and being in a fixed position with respect to said door;
a door actuator having a fluid operated piston and a cylinder, said cylinder having a first end pivotally coupled to said first bracket and a second end spaced from said first end;
