Claims
[1] In a mortise lock assembly including a hub rotating along with a rotary ring
connected to a handle, opening a door by retracting and releasing a latch bolt
from a door frame in accordance with rotation of the hub, a hub-locking
apparatus for the mortise lock assembly, comprising:
a locking member preventing the hub from being rotated when one end is fitted into a groove of the hub and allowing rotation of the hub when the one end is
released from the groove; and
a pivot member joined with the locking member to pivot the locking member.
[2] The hub-locking apparatus for the mortise lock assembly as claimed in claim 1, wherein the pivot member includes a screw locking one part of the locking
member to pivot the locking member at a certain angle, and a motor rotating the screw, the screw being provided with a control plate of a conducting material in the locking member to control the rotational angle of the locking member, the
control plate being locked in the screw to move up and down, and the screw
being provided with a stopper of a conducting material at upper and lower
portions to stop the motor if the control plate is in contact with the stopper.
[3] The hub-locking apparatus for the mortise lock assembly as claimed in claim 1, wherein the hub is respectively provided inside and outside the door, and the
locking member has a width smaller than the distance between the hub inside the door and the hub outside the door so that the locking member moves along a
rotary shaft of the hub and is locked in only one of the two hubs.
[4] The hub-locking apparatus for the mortise lock assembly as claimed in claim 1, further comprising a release cam rotatably assembled into any one rotary shaft of the mortise lock assembly, pushing up the end of the locking member to release the locking member from the groove of the hub while rotating at a certain angle.

[5] The hub-locking apparatus for the mortise lock assembly as claimed in claim 4, wherein the release cam is provided with a wing at both sides, the wing having a projection fitted into a slot, the slot being formed in a release rotary shaft, and the release rotary shaft being designed to rotate only if a certain force or greater is
given by a rotary guide.
