Hingedly attached extensions (1) are movable between points under and around the base, free standing unit and free standing appliance. The extensions provide electric power through cordless connectors (4) and may be pivoted, hingedly attached or on slides. ## Claims ### Claim 1 A modular appliance system comprising: a plurality of modular appliances; and a base unit for supporting one or more modular appliances simultaneously, the base unit being arranged to be connected to an electrical source and having at least two upstanding electrical connectors adapted for engagement with complemental connectors on said respective appliances, thereby to connect the appliances to the electrical source, at least one of the electrical connectors being movable between a closed position within the base unit and an open position adjacent to and spaced apart from the base unit, in which said open position at least one of the electrical connectors can engage a complemental connector on an appliance. ### Claim 2 (depends on 1) A modular appliance system according to claim 1 wherein the base unit defines a cavity within which at least one of the electrical connectors is received in the closed position, the cavity having an opening to permit at least one of the electrical connectors to be moved out of the cavity into the opened position thereof. ### Claim 3 (depends on 2) A modular appliance system according to claim 2 wherein at least one of the electrical connectors is mounted on an extension arm which hingedly attached to the base unit. ### Claim 4 (depends on 2) A modular appliance system according to claim 2 wherein at least one of the electrical connectors is mounted on an extension arm which is slideably attached to the base unit. ### Claim 5 (depends on 2) A modular appliance system according to claim 2 wherein the base unit includes a fixed upstanding electrical connector mounted thereon and a locating formation for correctly locating an appliance on the base unit, with said fixed upstanding electrical connector in engagement with a complemental electrical connector on the appliance. ### Claim 6 (depends on 2) A modular appliance system according to claim 2 wherein at least one of the electrical connectors is connected by an electrical cable to the base unit. ### Claim 7 A modular appliance system comprising: a plurality of modular appliances; and a free-standing appliance arranged to be connected to an electrical source, the free-standing appliance having a housing defining a cavity within which at least one upstanding electrical connector is receivable, the cavity having an opening to permit said at least one upstanding electrical connector to be moved from a closed position within the cavity to an open position adjacent to and spaced apart from the free-standing appliance, in which open position at least one upstanding electrical connector can engage a complemental connector on a modular appliance, to connect the modular appliance to the electrical source. ### Claim 8 (depends on 7) A modular appliance system according to claim 7 wherein said at least one upstanding electrical connector is mounted on an extension arm which is hingedly attached to the free-standing appliance. ### Claim 9 (depends on 7) A modular appliance system according to claim 7 wherein said at least one upstanding electrical connector is mounted on an extension arm which is slideably attached to the free-standing appliance. ### Claim 10 (depends on 7) A modular appliance system according to claim 7 wherein said at least one upstanding electrical connector is connected by an electrical cable to the free-standing appliance.
