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 slide bar ( 75 ) is carried by pillars ( 76 ) on a base plate ( 77 ) which in use is attached to a wall or the like above a horizontal work surface. 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 for the corkscrew ( 57 ) is reversed to disengage the cork from the corkscrew ( 57 ). |
