Summary
The invention relates to an arrangement for levelling a caravan in the form of a graduated, colour coded and numbered spirit level together with a series of associated interlocking ramps. Once the caravan is positioned in the preferred location, the spirit level is placed on the floor of the van parallel to the axle. The ramps used to level the caravan are themselves colour coded and numbered to correspond to the graduations on the spirit level. If the caravan is not level, displacement of the “bubble” relative to graduations indicates the number, size and combination of ramps required to level the van. The appropriate arrangement of ramps, as indicated by the spirit level, is then placed beneath the wheels of the caravan, and the wheels secured in place on the uppermost ramp by a combination of chocks and/or lips built into the surface of the ramp.
It is important to note that the ramps have different dimensions, and that movement of the bubble relative to the graduations does more than just identify the number of ramps required to level the caravan, but more importantly identifies a unique combination of different sized ramps which are required to level the van. For example, “mark 4” on the spirit level would indicate that the caravan needs to be lifted by 50mm, and that this can be achieved by placing a combination of ramps 1, 2 & 6 beneath the wheels. Prior-art arrangements having provided a mere indication of the number of equally sized ramps required to level the van. This provides a degree of flexibility in achieving a wider range of incremental heights than previously would have been available.
The Hearing Officer found that the invention as claimed was both novel and inventive.
