Claim Text:
1. A double door coordinator comprising: a body including a first end and a second end spaced from the first end along a longitudinal axis, with the body adapted to be fixed to a door frame, with an inactive door and an active door adapted to be mounted to the door frame, with each of the active door and the inactive door pivotable between a closed position and a non-closed position; a lever including a pivotal end pivotably mounted to the first end of the body, with the lever further including a driven end and a pull end, with the lever pivotable relative to the body between a protruded position in which the driven end is located outside of the body and a retracted position in which the driven end is located in the body, with the driven end of the lever adapted to be aligned with the inactive door, wherein the lever is in the retracted position when the inactive door is in the closed position, and wherein the lever is in the protruded position when the inactive door is in the non-closed position; a supporting block fixed between the first and second ends of the body; a stopper slideably received in the body, with the stopper including a stop end and a pivotal portion, with the stop end including a first stop face and a second stop face spaced from the first stop face, with the stopper movable along the supporting block between a front position in which the second stop face abuts the supporting block and a rear position in which the second stop face is spaced from the supporting block; a return spring including a first end mounted to the stopper and a second end mounted to the body, with the return spring biasing the stopper to the front position; a cable including a first end connected to the pull end of the lever and a second end pivotably connected to the stopper, with the cable moving the stopper from the front position to the rear position when the lever pivots from the protruded position to the retracted position; an actuation rod including a pivotal end, an actuation end, and a groove between the actuation end and the pivotal end, with the groove including a front end and a rear end spaced from the front end along a longitudinal axis of the groove, with the actuation end facing the first stop face of the stopper, with the actuation rod pivotable relative to the body about a pivotal axis between a first position in which the actuation end is located outside of the body and a second position in which the actuation end is received in the body, with the actuation end of the actuation rod adapted to be aligned with the active door, wherein the actuation rod is in the first position when the active door is in the non-closed position, and wherein the actuation rod is in the second position when the active door is in the closed position; a restraining rod fixed to the second end of the body and extending through the groove of the actuation rod, with the actuation rod movable relative to the stopper and the restraining rod along the longitudinal axis of the groove, and with the restraining rod defining the pivotal axis of the actuation rod, a buffering spring received in the groove of the actuation rod, with the buffering spring biasing the actuation rod to abut against the first stop face of the stopper, wherein when the lever is in the protruded position, the stopper is in the front position, the first stop face of the stopper is in a pivotal path of the actuation end of the actuation rod from the first position to the second position, wherein when the lever is in the retracted position, the stopper is in the rear position, the first stop face of the stopper is outside of the pivotal path of the actuation end of the actuation rod from the first position to the second position, permitting pivotal movement of the actuation rod from the first position to the second position, with the lever in the protruded position and with the actuation rod in the first position, when the actuation rod is moved from the first position to the second position by an external force larger than an elastic force of the buffering spring, the actuation rod moves relative to the stopper and the restraining rod along the longitudinal axis of the groove to a position in which the actuation end of the actuation rod is spaced from the first stop face of the stopper, permitting the actuation rod to pivot from the first position to the second position, and with the lever in the protruded position and with the actuation rod in the first position, when the external force moving the actuation rod from the first position to the second position is smaller than the elastic force of the buffering spring, the actuation end of the actuation rod remains abutting the first stop face of the stopper, not permitting the actuation rod to pivot from the first position to the second position.
