An emergency illumination apparatus is integrated into a door lock mechanism including a manual release member and a latch which is displaceable between an engaged position with the jamb of an associated exit door, and a disengaged position, enabling opening of the door. The apparatus includes an illumination device including a base member mounted to the door lock mechanism or a surface of the associated exit door and a spaced array of discrete illumination elements extending along at least one axis intersecting with or circumventing the manual release member. A sensor operates to detect an emergency condition such as the presence of excessive heat, smoke, carbon monoxide, noxious gas and the like, and generate an alarm signal in response thereto. An independent power supply is disposed within the emergency door lock illumination apparatus. A controller energized by the power supply activates the illumination device in response to the alarm signal.

A lock assembly has an actuator that is moveable between first and second positions and a locking structure that is coupled to the actuator. The locking structure is positioned to engage a portion of a lock when the actuator is in the first position to prevent movement of the actuator to the second position. A latch assembly is preferably coupled to the actuator and includes a latch that is moveable between engaged and disengaged positions. Moving the actuator from the first position to the second position moves the latch to the engaged position, and moving the actuator from the first position to a third position moves the latch to a disengaged position.

A latch arrangement for fastening a panel of a door or a window to a frame element, the panel including a depression is provided. The latch arrangement includes a locking element pivotally mounted an the frame element and displaceable between a locked position in which the locking element is engaged with the depression of the panel locking thereby the panel to the frame element, and an unlocked position in which the locking element is disengaged from the depression of the panel unlocking thereby the panel from the frame element, a stop latch selectively deployable to secure the locking element in the locked position, precluding thereby displacement of the locking element to the unlocked position; and an actuating mechanism configured to selectively pivot the locking element away from the depression to the unlocked position.

A latch arrangement for fastening a panel of a door or a window to a frame element is provided. The latch arrangement includes a locking element mounted on the frame element and displaceable between a locked position in which the locking element can be engaged with a depression formed on the panel locking thereby the panel to the frame element, and an unlocked position in which the locking element can be disengaged from the depression on the panel unlocking thereby the panel from the frame element; an actuating mechanism including a manually operable handle, the actuating mechanism being mounted on the panel and being configured to selectively engage the locking element and to displace the locking element away from the depression to the unlocked position.

A cross bar type unlock-driving structure, to be mounted in a panel-outside space of a door panel, includes a handle-end frame, a mounting frame, a handle and a driving member, and a handle seat. The handle-end base includes a basic frame and a mounting frame to form an accommodation space with both vertical and horizontal opening. The handle and the driving member, integrated as a unique piece, provide the driving member to be formed as an extension finger for pushing an unlock-driven unit disposed inside the accommodation space. The handle seat, mounted onto the middle plate of the mounting frame, is to mount pivotally the handle and the driving member with the driving member located in the accommodation space and the handle located out of the handle seat. With the vertical and horizontal opening provided to the accommodation space, different types of lock cartridges can be contained.
