An interlocking device includes two opposed racks having intermeshable teeth, respectively, a guide surface disposed on one of the opposed racks, a guide, and a resilient retainer holding the guide against the guide surface for sliding movement of the guide relative to the guide surface. The guide and the guide surface cooperate with each other to provide an arrangement wherein when the one rack is pressed against the other rack, the guide comes into engagement with the other rack and the guide surface slides on the guide, causing meshing engagement of the teeth of the one rack with the teeth of the other rack. <IMAGE> |
