Level corkscrew having a double fulcrum and method of using same

摘要

The invention relates to a corkscrew (T) including a handle (100) to which are connected a worm (200) and two separate levers (300, 400) pivotably connected in a case on a single pin (A) secured to the handle and preformed to provide the two notches or two fulcra (310, 410) that are required in order to extract a cork (B) inserted in the neck (G) of a bottle, in two steps. Said corkscrew is characterized in that the two levers include two portions, the second portion (330) of the first lever (300) being preformed such as to be inserted in the second portion (430) of the second lever (400) and create a fulcrum on the neck (G) of the bottle when the corkscrew (T) passes from the first notch (310) to the second notch (410) such that said first notch (310) does not project in relation to the second notch (410) and said first notch (310) does not prevent said passing. The invention also relates to the method for using the corkscrew described above. The invention is useful for manufacturing corkscrews.

主权项

1. A corkscrew for extracting a cork from the neck of a bottle comprising:
a handle comprised of a first pivot pin to which is articulated a worm and a second pivot pin to which is articulated a first lever and a second lever, where both levers 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 second pivot pin, and the first part of the first lever having a distal end that 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 where the second lever is comprised of a first part of the second lever mounted to the second pivot pin, and a second part of the second lever joined to the first part of the second lever, having a distal end that 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 the second part of the first lever 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, and where the distal end of the second part of the first lever extends past the notch formed by the second lever, where the first part of the first lever is comprised of a U-shaped profile and the first part of the second lever fits into the U-shaped profile of the first part of the first lever.
