<p>A cover system for a vehicle having an open-topped container, for example a skip (5, Figure 1), comprises a pair of swinging arms 13 mountable on either side of the vehicle to move between stowed and deployed positions to extend a flexible cover 11 over the top of the container. Cover 11 may be extended or retracted, for example by unwinding and rewinding, in response to movement of swinging arms 13. During deployment, swinging arms 13 are relatively moveable, for example using a mechanism comprising undulating cams (39, 41, Figure 5) with alternating peaks (43, Figure 5) and troughs (45, Figure 5), to change the spacing between them. For example, arms 13 may be at a minimum spacing when stowed and deployed and at a maximum spacing at an intermediate position; this may provide increased clearance for the container when deploying cover 11.</p> |
