Abstract
The lock of the passive door blade of a double door according to the invention comprises a lock body (23), a latch (17) and a control wedge (18). The control wedge is arranged to linearly move to a position extended out from the lock and to a position retracted inside the lock. The lock additionally comprises a lever (20), a leading shaft (21) and a spring system (27). The lever (20) is rotatably attached (25) to the control wedge (18) by its first end and rotatably attached (24) to the leading shaft (21) by its second end. The leading shaft (21) is additionally rotatably attached (22) to the lock body (23) and the leading shaft comprises a control cam (26) being in connection with the latch (17). The lever (20) and the leading shaft (21) are arranged to transfer the force of the spring system (27) to the control wedge (18) so that the force parallel with the linear movement of the control wedge is at its largest in the extended position of the control wedge and at its smallest when the control wedge is in the retracted position inside the lock.
