主权项

1. An assembly for converting motion, the assembly comprising:
a first arm rotatable at a first position on said first arm about a first fixed pivot; a second arm rotatable at a first position on said second arm about a second fixed pivot, the second fixed pivot spaced apart from the first fixed pivot; a third arm pivotably connected at a first position on said third arm to the second arm at a second position on the second arm, the second position spaced apart from the first position on the second arm; a fourth arm pivotably connected at a first position on said fourth arm to the second arm at a third position on the second arm; a fifth arm; a first connecting arm extending between the first arm and the third arm, the first connecting arm pivotably connected at a first position on said first connecting arm to a second position on the first arm spaced apart from the first position on the first arm and pivotably connected at a second position on said first connecting arm to the third arm at a second position on said third arm spaced apart from the first position on said third arm; a second connecting arm extending between the first arm and the second arm, the second connecting arm pivotably connected at a first position on said second connecting arm to a third position on the first arm disposed between the first and second positions on said first arm and pivotably connected at a second position on said second connecting arm to a fourth position on the second arm; a third connecting arm extending between the first arm and the fourth arm and between the fourth arm and the fifth arm, the third connecting arm pivotably connected at a first position on said third connecting arm to a fourth position on the first arm, pivotably connected at a second position on said third connecting arm to a third position on the fourth arm, and pivotably connected at a third position on said third connecting arm to a first position on the fifth arm; and a fourth connecting arm pivotably connected at a first position on said fourth connecting arm to the fourth arm at a second position on the fourth arm and pivotably connected at a second position on said fourth connecting arm to the fifth arm at a second position on the fifth arm; the fifth arm pivotably connected at a second position on said fifth arm to the third connecting arm; the fifth arm being mounted to an object to be moved.
