Transmission device for an exit device for a door

A transmission device for an exit device for a door comprising:

• a base including an extension;
• a transmission member pivotably mounted to the base, with the transmission member pivotable relative to the base between a first angular position and a second angular position, with the transmission member including a push portion;
• a driving member pivotably mounted to the extension of the base, with the driving member pivotable relative to the base between a third angular position and a fourth angular position, with the driving member including a pushed section and a push section, with the pushed section of the driving member abutting the push portion of the transmission member;
• a link movably mounted to the base, with the link adapted to be connected to a latch of an exit device for a door, with the link movable relative to the base between a first position and a second position, with the latch adapted to move between a latching position and an unlatching position respectively corresponding to the first and second positions of the link, with the link including a pushed portion located adjacent to the push section of the driving member;
• and
• at least one limiting member mounted to the base and including a groove, with the link including a lateral side movably received in the groove of the at least one limiting member,
• wherein when the transmission member pivots from the first angular position to the second angular position, the push portion of the transmission member pushes the pushed section of the driving member to pivot the driving member from the third angular position to the fourth angular position, and the push section of the driving member pushes the pushed portion of the link to move the link from the first position to the second position.

A transmission device for an exit device for a door comprising:

• a base including a slot having a side, with an extension extending from the side of the slot of the base and having a hole;
• a transmission member pivotably mounted to the base, with the transmission member pivotable relative to the base between a first angular position and a second angular position, with the transmission member including a push portion;
• a driving member pivotably mounted to the extension of the base, with the driving member pivotable relative to the base between a third angular position and a fourth angular position, with the driving member including a first end, a push section, and a hole, with the first end of the driving member including a pushed section, with the first end of the driving member extending through the slot of the base, with the pushed section of the driving member abutting the push portion of the transmission member;
• a pin extending through the hole of the driving member and the hole of the extension of the base to pivotably mount the driving member to the base;
• a link movably mounted to the base, with the link adapted to be connected to a latch of an exit device for a door, with the link movable relative to the base between a first position and a second position, with the latch adapted to move between a latching position and an unlatching position respectively corresponding to the first and second positions of the link, with the link including a pushed portion located adjacent to the push section of the driving member;
• and
• at least one limiting member mounted to the base and including a groove, with the link including a lateral side movably received in the groove of the at least one limiting member,
• wherein when the transmission member pivots from the first angular position to the second angular position, the push portion of the transmission member pushes the pushed section of the driving member to pivot the driving member from the third angular position to the fourth angular position, and the push section of the driving member pushes the pushed portion of the link to move the link from the first position to the second position.
