DESCRIPTION OF EMBODIMENTS
The modular appliance system illustrated in FIG. 1 comprises a generally planar base unit 10 which is moulded from a suitably tough and heat resistant plastics material such as polypropylene, and a set of modular appliances 12, 14 and 16 which can be mounted on the base unit individually or together, on the base 10 and extensions 1 and electrical connectors 2. The base 10 can be formed from other suitable plastics or materials including metals such as stainless steel or natural materials such as marble or wood.
In FIG. 1, the appliance 14 is a cordless kettle, the appliance 12 is a toaster and the appliance 16 is a chopper. It will be appreciated that the illustrated appliances are merely exemplary, and that the set of appliances usable on the base 10 may include various other appliances, or more than one identical appliance.
The base 10 may be rectangular and is provided with a locating formation in the form of an upstanding housing 1 locating step 3. The base 10 has a central upstanding cordless connector 4 of a kind known as such which mates with a complemental connector on the underside of the appliances 12, 14 and 16. The base 10 comprises extensions 1 and upstanding cordless connectors 2 which are hingley attached via hinge 6 to the base 10 so that the upstanding cordless connectors 2 may move out of the upstanding housing 1 locating step 3 on the extensions 1 in an arc from the underside 5 of the base 10 into a position away from the base 10 so that appliances 12, 14 and 16 may be located with its complemental connector to the upstanding connectors 2. On base 10, on the upstanding housing 1 locating step 3 there is provided a safety cut out 7 and an electric cable 8 which provides electric current to the base 10, extensions 1 and ultimately the cordless connectors 4 and 2.
