摘要：A mechanism (14) for adjusting the height of at least a part of an item or article,for example a home appliance such as a refrigerator, dishwasher or laundry washingmachine. The device (14) includes two parts and is adapted to replace at least a frontfoot of the item. A first part (3) of the device is an enlarged diameter thumb wheel whichis rotated by a user. The thumb wheel (3) is held within a captive nut (6) within theappliance thus rotation of the thumb wheel (3) increases or decreases the height of theappliance from the floor. The second part of the device (2) is a disk which is held captivewithin the thumb wheel (3) but which is in contact with the floor. The materials selectedand the geometry of the mating surfaces of the two components is chosen such that alow co-efficient of friction is produced between them.
