Level Corkscrew Having a Double Fulcrum and Method of Using Same

A corkscrew for extracting a cork from the neck of a bottle comprising:

• a handle on which are articulated a worm and a first lever and a second lever, both of which are articulated in a case on a pivot pin joined to the handle and are shaped in order to provide a first and a second notch that in operation act as a first and second corresponding fulcrum during the extraction of the cork,
• where the first lever is comprised of a first part of the first lever mounted to the pivot pin having a U-shaped profile of which the distal end forms the first notch which serves in operation as the first fulcrum for extracting the cork, and a second part of the first lever joined to the first part of the first lever and extending from the first part of the first lever past the first fulcrum and forming a mechanical abutment that in operation comes into contact with the cylindrical surfaces of the neck of the bottle;
• and
• a second lever comprised of a first part of the second lever mounted to the pivot pin, and a second part of the second lever joined to the first part of the second lever, having a U-shaped profile of which the distal end forms a second notch serving in operation as the second fulcrum against the neck of the bottle for extracting the cork,
• where the said second part of the first lever is shaped in such a way that it is accommodated in the said second part of the second lever and, in operation forms a fulcrum against the cylindrical surfaces of the neck of the bottle when the corkscrew position moves from the first notch to the second notch in such a way that the said first notch does not project with respect to the second notch and that the said first notch does not impede said movement.
