<p>Garage extension apparatus comprising a pair of channel section guide tracks (11 and 12), one on each sidewall of the garage (10), and a movable structure (13) formed of a roof (14), depending sidewalls (15 and 16) and an up-and-over door (17). The structure is supported on a pair of ground engaging wheels (18 and 19), each mounted at the front of a respective one of the sidewalls (15 and 16) by a screw jack (27), and on a pair of upper wheels (21 and 22) which each run in the channel of a respective one of the guide tracks (11 and 12) and which are pivotally mounted at the rear of the roof (14), so that the movable structure (13) can follow the slope of the carriageway, up or down, as it is drawn out of the garage. The screw jacks (27) enable the movable structure (13) to be levelled if the ground slopes from one side to the other.</p> |
