摘要： A ratchet apparatus includes a first member, a rack, and a second member that is selectively movable in first and second directions with respect to the first member. A first pawl is mounted with respect to the first member and is biased into engagement with the rack. The first pawl and the rack are configured such that engagement of the first pawl with the rack prevents movement of the first pawl relative to the rack in the first direction. A second pawl is mounted with respect to the second member for movement therewith in the first and second directions. The second pawl is biased into engagement with the rack. The second pawl and said rack are configured such that engagement of the second pawl with the rack prevents movement of the second pawl relative to the rack in the first direction.

摘要： A cam lift and reset assembly includes a cam mounted on a rotatable shaft having a cam profile effective to provide a lifting force to a contacted part thereon upon rotation of the shaft and movement of the cam profile of the cam relative to the contacted part from a rest position to a lift position. The assembly also includes an active material in operative communication with the shaft, the active material being operative to change at least one property of the active material in response to an activation signal so as to effect rotation of the shaft. The assembly further includes a reset device in operative communication with the shaft to provide a reset force to the contacted part and counter-rotation of the shaft and movement of the cam profile of the cam relative to the contacted part from the lift position to the rest position.
