The invention relates to an espagnolette (1) for the fixed leaf of a double-leaf door, having a lock case (5) in which there is mounted a handle follower (9) by rotational actuation of which at least one driving rod (20, 26) can be displaced parallel to a lock case front (6), the end of the rod forming or controlling a bolt, the espagnolette having an entry opening (7, 8) for a bolt (4) or a latch (3) of a lock (2) associated with the moving leaf, a driving-rod connection slide (20, 26) which is guided in the lock case (5) being assigned a blocking element (28, 29) which, in the open position of the lock mechanism (1), is located in the region of the entry opening (7, 8), in order to obstruct the entry of the bolt (4) of the moving-leaf lock mechanism, and, in the locked position of the lock mechanism (1), is located outside the region of the entry opening (8) such that the displaceability of the driving rod (26) into the open position can be blocked by entry of the bolt (4) of the moving-leaf lock mechanism. In order to improve a fixed-leaf lock mechanism of a door lock for a double-leaf door, it is proposed that the follower (9) acts on the driving rod (26) by way of a lever-transmission mechanism (H), a link (11) which acts, at one end, on a driving-rod drive lever (13) and, at the other end, on an arm (10) of the handle follower (9) being brought over a dead-center position (T) when the follower (9) is rotated.
An espagnolette (1) for the fixed leaf of a double-leaf door, having a lock case (5) in which there is mounted a handle follower (9) by rotational actuation of which at least one driving rod (20, 26) can be displaced parallel to a lock case front (6), the end of the rod forming or controlling a bolt, the espagnolette having an entry opening (7, 8) for a bolt (4) or a latch (3) of a lock mechanism (2) associated with the moving leaf, a driving-rod connection slide (20, 26) which is guided in the lock case (5) being assigned a blocking element (28, 29) which, in the open position of the lock mechanism (1), is located in the region of the entry opening (7, 8), in order to obstruct the entry of the bolt (4) of the moving-leaf lock mechanism, and, in the locked position of the lock mechanism (1), is located outside the region of the entry opening (8) such that the displaceability of the driving rod (26) into the open position can be blocked by entry of the bolt (4) of the moving-leaf lock mechanism, characterized in that the follower (9) acts on the driving rod (26) by way of a lever-transmission mechanism (H), a link (11) which acts, at one end, on a driving-rod drive lever (13) and, at the other end, on an arm (10) of the handle follower (9) being brought over a dead-center position (T) when the follower (9) is rotated.
Espagnolette according to one or more of the preceding claims or in particular according thereto, characterized by a spring (16) which loads the driving rod (26) in the direction of the open position.
Espagnolette according to one or more of the preceding claims or in particular according thereto, characterized in that the spring (16) acts on the driving-rod drive lever (13).
Espagnolette according to one or more of the preceding claims or in particular according thereto, characterized by two driving-rod connection slides (20, 26) which can be displaced in opposite directions and are coupled to one another for movement via a toothed-wheel drive.
Espagnolette according to one or more of the preceding claims or in particular according thereto, characterized by a second entry opening (7) for a latch (3) or a bolt of the moving-leaf lock mechanism, said second entry opening likewise being assigned a blocking element (28).
Espagnolette according to one or more of the preceding claims or in particular according thereto, characterized in that each of the two driving-rod connection slides (20, 26) is assigned a blocking element (28, 29).
Espagnolette according to one or more of the preceding claims or in particular according thereto, characterized in that the blocking element (28, 29) is formed by an angled portion of the driving-rod connection slide (20, 26), which is produced as a punched and bent part.
Espagnolette according to one or more of the preceding claims or in particular according thereto, characterized in that the driving-rod connection slide (20, 26) can be blocked in its locked position by means of a blocking bolt (33).
Espagnolette according to one or more of the preceding claims or in particular according thereto, characterized in that the blocking bolt (33) can be displaced by the locking member (32) of a lock cylinder (31) and, in the blocking position, is located in the displacement path of the driving-rod connection slide (26).
Espagnolette according to one or more of the preceding claims or in particular according thereto, characterized in that, in its position in which it blocks the entry opening (7) of the latch (3) of the moving-leaf lock mechanism (2), the blocking element (28), which is associated with the latch (3), allows the latch (3) to spring part of the way in.
Espagnolette according to one or more of the preceding claims or in particular according thereto, characterized in that, in its blocking position, the blocking element (29), which is associated with the bolt (4) of the moving-leaf lock mechanism (2), allows the bolt (4) of the moving-leaf lock mechanism (2) to enter part of the way in.
Espagnolette according to one or more of the preceding claims or in particular according thereto, characterized in that the driving rods are secured in the locked position as a result of an over-dead-center position of the lever-transmission mechanism (H) driving them.
