Abstract
A device for opening and closing the seating plate of the lavatory unit of the seat type wherein the unit is provided with only the seating plate. The device includes a spring for connecting a movable member attached to the unit body with the seating plate freely swingably pivoted on the unit body at one end rim thereof, an opening mechanism for moving the movable member to reverse the urging direction of the spring from its seating-plate-closing direction to its seating-plate-opening direction, and a closing mechanism for causing the seating plate to be closed. When the opening mechanism is made operative, the urging direction of the spring is reversed to open the seating plate. When the unit is provided with the seating and the cover plate. The device includes a pair of springs for connecting a pair of movable members attached to the unit body with the seating and the cover plate, which movable members are freely swingably pivoted on the unit body at one end thereof, a pair of opening mechanism for moving each of the movable members to reverse the urging direction of each spring from its seating- or cover-plate-closing direction to its seating- or cover-plate-opening direction, an interlocking mechanism for interlocking the cover-plate-opening with the seating-plate-opening mechanism, and a closing mechanism for causing the cover plate to be closed. The cover plate is thus similarly opened by the urging action of the spring and when the seating plate is opened, the cover-plate-opening mechanism is interlocked with this seating-plate-opening action to open the cover plate.
