Abstract

A corkscrew assembly (50) has a tubular body (52) mounted on an upright slide bar (75) by means of a collar (72) which is connected to the body (52) by an arm (73).

The collar (72) can be moved up or down on the slide bar (75) for height adjustment of the body (52) to engage a mouth (85) at a lower end of the body (52) with the neck of a bottle placed on the work surface below the body (52). Locking means is provided on the collar (72) to releasably lock the collar (72) on the slide bar (75) when engaged with a bottle to securely hold the bottle for cork extraction. An actuating lever arm (68) on the body (52) can then be moved downwardly from a raised position to operate drive means on the body (52) to screw a corkscrew (57) into the cork of the bottle. When subsequently raised, the lever arm (68) initially extracts the cork from the bottle and engages the cork against an inner end (91) of a cork receiving chamber (90) in the body (52) when the lever arm (68) is partially raised. As the lever arm (68) is moved further upwards, the drive…
