An assembly 2 for converting motion, the assembly comprising a first arm 8 pivotally connected at a first fixed pivot 4 and second arm 10 is pivotally connected at a second fixed pivot 6. A third arm 12 is mounted at one end of the second arm 10 by a pivot connection 14. First and second connecting arms 16, 22 are connected to the first arm 8 and the third arm 12 by pivot connections 18, 20 14 and 24 so that movement of the arms 8, 10 about the pivots 4, 6 causes the third arm 12 to move such that point A moves from a retracted position to an extended position in a substantially straight line. A locking assembly, such as pin 40 and a receiving member, prevents movement beyond the extended position. In one embodiment a pair of linked assemblies (see fig 2) are provided on opposing sides of a component, e.g. a building, road sign, solar panel assembly. Also claimed is a building with the apparatus and an assembly having a guide assembly. |
