<P>PROBLEM TO BE SOLVED: To provide a low-cost stepped lifter device of simple structure excellent in operability capable of raising and lowering an elevating body especially stepwise. <P>SOLUTION: A pair of rising latch 27 and a lowering latch 28 are pivoted at an input member 20 supported rotatably by an elevating body to be engaged with and disengaged from a motion transmission ratchet 23 for rotating a teeth link 10T in interlocked manner. In the stepped lifter device, each time the input member 20 is swung in a direction from a neutral position to a rising position, engagement between the lowering latch 28 and the motion transmission ratchet 23 is released so that the teeth link 10T is rotated upward by engagement between the rising latch 27 and the motion transmission ratchet 23, and each time the input member 20 is swung from the neutral position to lowering position, the engagement between the rising latch 27 and the motion transmission ratchet 23 is released so that the teeth link 10T is rotated downward by engagement between the lowering latch 28 and a link ratchet 16. <P>COPYRIGHT: (C)2012,JPO&INPIT |
