Abstract

The corkscrew with lever includes a spiral mounted rotating on a zone of a handle between an end segment and a maneuvering segment, and a telescoping arm having a first element mounted rotating on the end segment and a second element, having an upper end and a lower end, mounted sliding in the first element between an idle position and a second position. The lower edge of the lower end of said second element is provided to bear on the neck of a bottle. The end segment defines a circular cam having, as center, the second axis and able to act on the upper end of the second element, which is connected to the second axis using a return member. In a usage position of the corkscrew, its upper end is continuously kept in contact with the cam and its lower end extends continuously outside the first element.

Claims

1. A corkscrew with lever comprising:

a handle comprised of an end segment and a maneuvering segment;

a spiral mounted rotating on a zone of said handle between said end segment and said maneuvering segment, around a first axis perpendicular to said handle; and

a telescoping arm having a first element mounted rotating on the end segment around a second axis perpendicular to said handle and a second element, having an upper end and a lower end, mounted sliding in said first element between an idle position in which the lower edge of its lower end is located at a distance from said second axis) and a second position in which the lower edge of its lower end is located at a distance-d from said second axis greater than the distance from said second axis in said idle position, the lower edge of the lower end of said second element being provided able to bear on the neck of a bottle,

wherein said end segment defines a circular cam having, as center, said second axis and able to act on the upper end of said second element, which is connected to said second axis using a return member,

wherein, in a usage position, said upper end is continuously kept in contact with said cam and its lower end extends continuously outside said first element.

2. The corkscrew, according to claim 1, wherein a profile of said cam comprises a first curve with a constant radius and a second curve with an increasing radius following one another between the intermediate zone of the handle bearing the first axis and the end edge of the end segment.

3. The corkscrew according to claim 2, wherein said profile further comprises a stop formed in the extension of the second curve of increasing radius.

4. The corkscrew according to claim 1, wherein said return member is an extension spring.

5. The corkscrew according to claim 1, wherein the second element is comprised of a U-shaped section and two side wings bordering a bottom, the lower edge of each of said side wings having a V-shaped cutout able to bear on the neck of a bottle and the upper end of said second element being comprised of at least one tooth extending in the extension of said bottom and said side wings and bearing on said cam.

6. The corkscrew, according to claim 5, wherein said second element comprises a notch formed in at least one of its side wings and able to allow the fastening of said return member.

7. The corkscrew, according to claim 1, wherein said spiral has an upper part with a rectangular section connected to said first axis and a side face oriented toward said telescoping arm, said upper part being provided with a groove with an axis parallel to the longitudinal axis of the spiral and the inlet opening of which is formed in said side face.

8. The corkscrew, according to claim 7, wherein said groove has a U-shaped section being comprised of a bottom delimited by a front wall and a rear wall, and wherein said front wall is connected to an upper zone of said side face by an oblique surface forming, with said front wall, an angle α

smaller than 90°

.

9. The corkscrew, according to claim 7, wherein the rear wall of said groove is connected to a lower zone of the side face by an oblique surface forming, with said rear wall, an angle β

greater than 90°

.

10. The corkscrew, according to claim 7, wherein said second element of said telescoping arm comprises an axis extending between its side wings at its lower end.
