Abstract
A mechanism 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 washing machine. The device includes two parts and is adapted to replace at least a front foot of the item. A first part of the device is an enlarged diameter thumb wheel which is rotated by a user. The thumb wheel is held within a captive nut within the appliance thus rotation of the thumb wheel increases or decreases the height of the appliance from the floor. The second part of the device is a disk which is held captive within the thumb wheel but which is in contact with the floor. The materials selected and the geometry of the mating surfaces of the two components is chosen such that a low co-efficient of friction is produced between them.
