Abstract

Improved corkscrew formed by a metal structure wherein a stop part rests on an bottle outlet, the stop part composed of two parts which are telescopically coupled and which can be locked into an extended position by means of a retaining element actuated by a flexible pusher thereby facilitating a progressive bearing position when removing a cork from said bottle.

Claims

1. An improved corkscrew, comprising:

a central structure

a lever grip mounted to said central structure at a first end thereof;

a helicoidal drill pivotally connected to a bottom side of said central structure;

a support piece pivotally connected to said central structure on another end thereof opposite the first end and having an interior region therein, said support piece comprising a first part and a second part that are mutually telescopically extendable between an unextended position and an extended position; and

a mobile pin disposed in the interior region of the support piece, said mobile pin being engageable with each of said first and second parts of said support piece thereby locking said first and said second parts into the unextended and the extended position.

2. The improved corkscrew as claimed in claim 1 further comprising a plurality of mutually corresponding holes in each of said first and second parts of said support piece into corresponding ones of which said mobile pin is mutually engageable.

3. The improved corkscrew as claimed in claim 1 wherein the telescopic extension of said support piece between the unextended and extended positions is progressive.

4. The improved corkscrew as claimed in claim 1 further comprising a flexible element disposed in the interior region, said flexible element biased against said mobile pin.

5. The improved corkscrew as claimed in claim 1 further comprising a cutting element mounted on said central structure.

6. The improved corkscrew as claimed in claim 5 wherein said cutting element is a knife-like blade.

7. The improved corkscrew as claimed in claim 5 wherein said cutting element is pivotally connected to said central structure.

8. The improved corkscrew as claimed in claim 5 wherein said cutting element is disposed on a front portion of said central structure.

10. The improved corkscrew as claimed in claim 1 wherein an outer one of said first and second parts of said support piece has a support notch disposed thereon.

11. The improved corkscrew as claimed in claim 1 wherein said central structure is stainless steel.

12. The improved corkscrew as claimed in claim 1, further comprising an anti-skid configuration on a surface of said lever grip.

13. The improved corkscrew as claimed in claim 1 wherein said lever grip is made of wood or plastic.

9. The improved corkscrew as claimed in claimed 1 further comprising a hook having a nail-like protuberance mounted on said central structure.
