Abstract
An indicator device for use in indicating whether or not a no-back device is operable, the indicator device comprising an indicator member 42 moveable between a first position and a second position, a biassing arrangement 56 being provided to urge the indicator member 42 towards its first position, and a latch arrangement 46 being provided to allow the indicator member 42 to be held, against the biassing load of the biassing arrangement 56, in its second position, the indicator member 42 being adapted such that, in use of the associated no-back device, movement of the pawl 30 of the no-back device causes the indicator member 42 to be moved out of its second position.
Claims12
An indicator device for use in indicating whether or not a no-back device having a pawl is operable, the indicator device comprising an indicator member moveable between a first position and a second position, a biassing arrangement being provided to urge the indicator member towards its first position, and a latch arrangement being provided to allow the indicator member to be held, against the biassing load of the biassing arrangement, in its second position, the indicator member being adapted such that, in normal use of the associated no-back device, movement of the pawl of the no-back device causes the indicator member to be moved out of its second position.
A no-back device comprising a toothed ratchet ring, at least one pawl co-operable with the teeth of the ratchet ring to allow rotation of the ratchet ring in a forward direction and prevent reverse rotation of the ratchet ring, and an indicator device operable to provide an indication that the pawl moves beyond a pre-determined position upon rotation of the ratcheting in the forward direction, the indicator device comprising an indicator member moveable between a first position and a second position, a biassing arrangement being provided to urge the indicator member towards its first position, and a latch arrangement to allow the indicator member to be held, against the biassing load of the biassing arrangement, in its second position, the indicator member being adapted such that, in normal use of the associated no-back device, movement of the pawl of the no-back device causes the indicator member to be moved out of its second position.
