Closing sequence control for a double-leaf door
The present invention relates to a closing sequence control for a double-leaf door, including a door having an inactive leaf and an active leaf, the door leaves thereof being movable by respectively one overhead door closer being mounted to the push-side of the door leaves at the inactive leaf and at the active leaf, wherein each overhead door closer includes a closer shaft, which is connected to the one end of a pivoting arm, which in turn, with its other end, is longitudinally movable guided in a frame-fixed guiding rail via a sliding member, and the sliding member, associated to the active leaf, is connected to a clamping rod which is supported in the guiding rail, which rod can be charged by a clamping element, which, when the inactive leaf is in the closing condition, is maintained in a releasing position by means of a trigger element, and, during an opening movement of the inactive leaf, it can be transferred into a blocking position by means of the trigger element. With the intention to configure such a closing sequence control in such a way that the door hinges of the door leaves can be disposed on the side facing away from the door closers, the guiding rail and the closing sequence control, wherein a reliable closing sequence control can be guaranteed without electrical, hydraulic or pneumatic control, according to the invention it is provided that the trigger element ( 8 ) is in operative connection with a double-armed lever ( 11 ), which can be charged by means of the closer shaft ( 5 ) of the overhead door closer ( 3 ) mounted to the inactive leaf ( 1 ) in such a way that the trigger element ( 8 ) transfers the blocking element ( 8 ) into its releasing position.
1 . A closing sequence control for a double-leaf door, including a door having an inactive leaf and an active leaf, the door leaves thereof being movable by respectively one overhead door closer being mounted to the push-side of the door leaves at the inactive leaf and at the active leaf, wherein each overhead door closer includes a closer shaft, which is connected to the one end of a pivoting arm, which, with its other end, is longitudinally movable guided in a frame-fixed guiding rail via a sliding member, and the sliding member, associated to the active leaf, is connected to a clamping rod which is supported in the guiding rail, which rod can be charged by a clamping element, which element, when the inactive leaf is in the closing condition, is maintained in a releasing position by means of a trigger element, and, during an opening movement of the inactive leaf, it can be transferred into a blocking position by means of the trigger element, wherein the trigger element is in operative connection with a double-armed lever, which can be charged by means of the closer shaft of the overhead door closer mounted to the inactive leaf in such a way that the trigger element transfers the blocking element into its releasing position.
2 . The closing sequence control according to claim 1 , wherein the double-armed lever is retained at a bearing block which is disposed at the guiding rail.
3 . The closing sequence control according to claim 2 , wherein the bearing block is configured as a U-shaped bracket, the open side thereof facing the overhead door closer.
4 . The closing sequence control according to claim 3 , wherein the double-armed lever is pivotally supported at the frontal side of the one leg of the U-shaped bracket.
5 . The closing sequence control according to claim 4 , wherein a bearing bore is provided in the other leg of the U-shaped bracket, in which bore the trigger element is slidably guided.
6 . The closing sequence control according to claim 3 , wherein the trigger element includes an essentially rectangular protruding arm, which is disposed between the legs of the U-shaped bearing block and protrudes beyond them.
7 . The closing sequence control according to claim 6 , wherein, at its protruding end, the arm is charged by means of the double-armed lever.
8 . The closing sequence control according to claim 7 , wherein, at its end protruding beyond the legs of the U-shaped bearing block, the arm is provided with a pin-shaped extension.
9 . The closing sequence control according to claim 1 , wherein the two arms of the double-armed lever are disposed at an angle with regard to each other.
10 . The closing sequence control according to claim 8 , wherein the one arm of the double-armed lever abuts at the pin-shaped extension, and the other arm of the double-armed lever can be charged by means of the closer shaft.
