<p>An assembly 2, for converting motion, is mounted to a fixed structure such as a building by fixed first and second pivot points 4, 6. A first arm 8 is connected to the first pivot point 4 and a second arm 10 is connected to the second pivot point 6. A third arm 12 is connected to the second arm 10 by a pivot connection 14. First connecting arm 16 is connected to the first and third arms 10, 12 by pivot connections 18, 20 and a second connecting arm 22 is connected to the first and second arms 8, 10 by pivot connections 14, 24. Drive applied to one of the first or second arms 8, 10 results in motion of the third arm 12 from a retracted or stowed position (fig 2a) to an extended position. Alternatively drive may be applied to the third arm 12 results in movement of the first and second arms 8, 10. The assembly 2 may be used for mounting solar panels or partitions or road signs to, for example, buildings.</p> |
