Abstract:
1. A corkscrew comprising: a casing; a downwardly opening socket within the casing, the socket having a vertical axis being dimensioned to receive the neck of a bottle; a corkscrew spiral arranged axially within the socket; a motor adapted to rotate the spiral in clockwise and anticlockwise directions; a battery; a sleeve having an axial bore mounted for axial movement within the socket; spring means adapted to bias the sleeve downwardly within the socket; a control circuit including a microprocessor and a memory; a display; and an upper position sensor; the motor upon actuation causing the spiral to rotate in a first direction to penetrate the cork and withdraw the cork from the bottle neck; the axial bore being configured to receive and engage the cork wherein axial splines extend inwardly of the bore to engage the cork preventing rotation of the cork; the upper position sensor being adapted to detect when the cork is completely removed from the bottle and to generate a signal to stop rotation of the spiral; the microprocessor being in electrical communication with the battery and being charged to determine whether the battery is able to perform sufficient work to open a cork and to provide a signal to the display indicating the number of corks which may be removed using the corkscrew.
