Patent ID: 8424930

Claim:
An apparatus comprising: a hand insertion window formed in a side of a newborn chamber; a hand insertion door that opens and closes the hand insertion window by rotation; a latch mechanism that holds the hand insertion door in a closing position for closing the hand insertion window; wherein the latch mechanism includes a latch and a releasing member, the latch has a rotation shaft extending along the side and enabling rotation between a holding position for the holding of the hand insertion door and an releasing position for releasing the holding of the hand insertion door, and a spiral face extending to at least part of a periphery of the rotation shaft; and the releasing member is movable along the side, and presses the spiral face by movement to cause the rotation of the latch from the holding position to the releasing position; and an opening mechanism configured such that in the course of the rotation of the hand insertion door in the direction in which the hand insertion window is closed, the opening mechanism comes into contact with the hand insertion door before the hand insertion window is closed, and thereby urges the hand insertion door to cause the rotation in the direction in which the hand insertion window is opened, wherein a packing is attached to an internal edge of the hand insertion window and the packing serves as the opening mechanism. further wherein the packing has a thicker portion and the thicker portion serves as the opening mechanism, wherein the latch has a pressed portion that is pressed by the rotation of the hand insertion door, and thereby causes the rotation from the holding position to the releasing position, and the pressed portion is made of impact-absorbent material.
