Abstract
In combination, a door, two latches at an edge of the door, and door latch operating components at opposite sides of the door; displaceable structure in the door having a position blocking movement of the latches, first mechanism responsive to displacement of one of the components for displacing the structure from blocking position to allow movement of the latches, for door opening; and electrically operable actuating means for effecting displacement of the structure from blocking position to allow movement of the latches, for door opening.
Claims21
In combination:
- a) a door, two latches at an edge of the door, and door latch operating components at opposite sides of the door,
- b) displaceable structure in the door having a position blocking movement of the latches,
- c) first means responsive to displacement of one of the components for displacing said structure from said blocking position to allow movement of the latches, for door opening, and
- d) electrically operable actuating means for effecting displacement of said structure from said blocking position to allow movement of the latches, for door opening,
- e) said structure including a slider displaceable in response to operation of said first means, and also displaceable in response to operation of said electrically operable actuating means,
- f) said electrically operable actuating means being operatively decoupled from the slider when said first means is operatively coupled to the slider, and wherein said first means is operatively decoupled from the slider when the electrically operable actuating means is operatively coupled to the slider.
