An assembly 2 for converting motion comprising a first arm 8 rotatable at a first position about a first fixed pivot 4; a second arm 10 rotatable at a first position about a second fixed pivot 6; a third arm 12 pivotably connected at a first position on the third arm to a second position on the second arm spaced from the first position; a fourth arm 16 pivotably connected to a second position on the first arm spaced from the first position and to a second position on the third arm spaced from the first position; a connecting arm 22 pivotably connected to the second position on the first arm and to a third position on the second arm between the first and second positions; with a point A on the third arm spaced from the first position on the third arm and located such that the second position on the third arm lies between the point and the first position, movement of the third arm between a retracted position and an extended position causing the point to move in a substantially straight line extending perpendicular to the line joining the first and second fixed pivots. The assembly may be used to extend balconies, walls, floor or roof extensions, or canopies from a house, apartment, office building, or caravan, or to move a video or television screen or a monitor.
