    • PURPOSE:To enlarge the opening or closing width of a door and enable working to be curved and contrive a device to be accommodated to the opening or closing of the door of an altar by engaging the doors respectively with the left and right tips of pantagraphs, and by fixing the one side of a set of telescopic fulcrums at a fixed position, to fit a combined element on the other fulcrum and to engage the element with a combined shaft. CONSTITUTION:A plurality of respective pantagraphs are combined with each other in series, and the tips of both the sides are respectively engaged with doors 2, 2'. When the pantagraphs are opened or closed to left or right, then the one side 3 of a set of fulcrums moving telescopically to be confronted with each other is fixed at a position in a state that the pantagraphs are shrunk most. On a fulcrum 4 on the counter side moving telescopically to be confronted with 3, a combined element is fitted. A combined shaft 5 engaged with the combined element 4 is connected to a fixed prime mover 6. When the prime mover ia rotated forward, then the combined element engaged with the combined shaft is shrunk to come closer to the fixed fulcrum, and the pantagraphs are opened to the left and right, and the fulcrum on one side is fixed, and so the door engaged with the tip is extended in the shape of a curve. Besides, when the prime mover is reversely rotated, then the door is shrunk according to the curve and is returned to an original position.
