A mechanical lock 10 for a vehicle assembly such as an aircraft landing gear assembly enables or prevents movement between two components. A first component includes a first part 12 pivotal about an axis 14 and has a generally circular peripheral surface 12a and a bearing surface 12b. A second component includes a second part 16 pivotal about an axis 18 and has a generally circular peripheral surface 16a and a bearing surface 16b. When the two components are in a lockable configuration the second part can be manually rotated to a condition (fig 2b) where the two components 32,34 cannot be moved relative to one another. The lock is either pivotally mounted and substantially mass balanced, or part of an aircraft landing gear assembly 30 and arranged to be mechanically operated from the ground by a mechanical actuation device. |
