Abstract

A corkscrew assembly contains the combination of a body, a corkscrew and a lever, in which the lever has a lever extension slidably nested within a recess therein, the extension being movable between a first and second position and the extension extends beyond the free end of the lever in the second position.

Claims

1. In a corkscrew assembly comprising a body, a corkscrew attached to the body and a lever spaced from said corkscrew and having one end pivotally attached to the body, the improvement which comprises the lever having a groove extending from a second end of the lever toward said one end and having a lever extension slidably nested in said groove and being slidably movable between a first and second position, wherein the extension extends beyond said second end in said second position.

2. The corkscrew assembly of claim 1, wherein the corkscrew is pivotally attached to the body and the lever and lever extension have U-shaped cross-sections.

3. The corkscrew assembly of claim 2, having a knife pivotally attached to the body.

4. A corkscrew assembly comprising an elongated body;

a corkscrew pivotally attached to a generally central location along an axis of said elongated body;

a variable length lever assembly comprising first and second elongated members slidably attached to one another;

said first elongated member being pivotally attached to one end of said elongated body;

said elongated body having a cam surface disposed adjacent said one end of said elongated body;

one end of said second elongated member being slidably coupled to said cam surface, whereby said second elongated member is longitudinally moved relative to said first elongated member when said first elongated member is rotated at least through a given range, relative to said one end of said elongated body.

5. The corkscrew assembly of claim 4, wherein said first and second elongated members have U-shaped cross-sections.

6. The corkscrew assembly of claim 5, wherein said second elongated member is disposed within said U-shaped cross-section of said first elongated member.

7. The corkscrew assembly of claim 6, having a knife blade pivotally attached to said elongated body at a point distant from both said corkscrew and said lever assembly.

8. The corkscrew assembly of claim 7, wherein one of said first and second elongated members has a slot along the axis of said elongated member and having a rivet passing through said slot and the other of said first and second elongated members.

9. The corkscrew assembly of claim 8 which further includes a biasing spring connected between said first and second elongated members for biasing said second member into contact with said cam surface.

10. The corkscrew assembly of claim 9 wherein said first elongated member has a flange disposed at a point distant from the point of pivotable attachment and one end of said biasing spring abuts said flange.

11. The corkscrew assembly of claim 10 wherein said flange is disposed at a point further from the point of pivotable attachment than said rivet and wherein said elongated body has first and second recesses disposed on opposite sides of said axis adapted to receive at least a portion of said corkscrew and knife, respectively, at one position through which said corkscrew and knife, respectively, can be pivoted.

12. The corkscrew assembly of claim 4 which further includes a biasing spring connected between said first and second elongated members for biasing said second member into contact with said cam surface.

13. The corkscrew assembly of claim 12 wherein said first elongated member has a flange disposed at a point distant from the point of pivotable attachment and one end of said biasing spring abuts said flange.
