Abstract

A corkscrew assembly includes a housing a worm screw assembly, a first gripper, and a second gripper. The housing defines (i) a first opening configured to receive a neck of a bottle, (ii) a second opening, and (iii) an interior space interposed between the first opening and the second opening. The housing includes a sidewall extending from the first opening to the second opening. The sidewall defines a first gripper passage and a second gripper passage. The interior space is interposed between the first gripper passage and the second gripper passage. The worm screw assembly is rotatable in relation to the housing and includes (i) a worm screw member having a pointed first end portion and a second opposite end portion and (ii) a drive member fixed in relation to the second opposite end portion.

First claim

What is claimed is:

1. A corkscrew assembly, comprising:
a housing defining (i) a first opening configured to receive a neck of a bottle, (ii) a second opening, and (iii) an interior space interposed between said first opening and said second opening, said housing including a sidewall extending from said first opening to said second opening, said sidewall defining a first gripper passage and a second gripper passage, and said interior space being interposed between said first gripper passage and said second gripper passage;
a worm screw assembly rotatable in relation to said housing and including (i) a worm screw member having a pointed first end portion and a second opposite end portion and (ii) a drive member fixed in relation to said second opposite end portion, said worm screw assembly being configured such that rotation of said drive member causes rotation of said worm screw;
a first gripper movable in relation to said housing and extending through said first gripper passage;
a second gripper movable in relation to said housing and extending though said second gripper passage;
a first biaser connected to said first gripper; and
a second biaser connected to said second gripper,
wherein said first gripper, said second gripper, said first biaser, and said second biaser are integrally formed as a single part from an elastomeric material.

2. The corkscrew assembly of claim 1 , wherein:
said first gripper is movable between a first position and a second position,
said first biaser is configured to urge said first gripper toward said first position,
said second gripper is movable between a third position and a fourth position, and
said second biaser is configured to urge said second gripper toward said third position.

3. The corkscrew assembly of claim 2 , wherein:
said worm screw assembly defines a longitudinal axis that extends through both said first opening and said second opening,
said first biaser is configured to urge said first gripper from said second position to said first position in a first direction away from said longitudinal axis, and
said second biaser is configured to urge said second gripper from said fourth position to said third position in a second direction away from said longitudinal axis.

4. The corkscrew assembly of claim 1 , wherein:
said worm screw assembly further includes an interface structure,
said drive member is attached to said interface structure, and
said second opposite end of said worm screw is attached to said interface structure.

5. The corkscrew assembly of claim 4 , wherein:
said drive member is made of metal,
said interface structure is made of plastic, and
said worm screw member is made of metal.

6. The corkscrew assembly of claim 4 , wherein said interface structure defines:
a first recess in which at least a portion of said drive member is positioned, and
a second recess in which at least a portion of said second opposite end of said worm screw member is positioned.

7. The corkscrew assembly of claim 4 , wherein:
said housing includes a bore structure defining a cylindrical interior bearing surface, and
said worm screw member is positioned in contact with said cylindrical interior bearing surface during rotation of said worm screw assembly.

8. The corkscrew assembly of claim 4 , further comprising a cap attached to said housing, wherein:
said housing further includes an abutment structure located in said interior space,
said interface structure includes a stop,
said worm screw assembly is movable in relation to said housing between a first position and a second position,
when said worm screw assembly is positioned in said first position, said stop is positioned in contact with said abutment structure, and
when said worm screw assembly is positioned in said second position, said stop is positioned in contact with said cap.

9. The corkscrew assembly of claim 8 , wherein:
said cap defines a cylindrical interior bearing surface, and
said interface structure is positioned in contact with said cylindrical interior bearing surface during movement of said worm screw assembly from said first position to said second position.

10. A corkscrew assembly, comprising:
a housing defining (i) a first opening configured to receive a neck of a bottle, (ii) a second opening, and (iii) an interior space interposed between said first opening and said second opening, said housing including a sidewall extending from said first opening to said second opening, said sidewall defining a first gripper passage and a second gripper passage, and said interior space being interposed between said first gripper passage and said second gripper passage;
a worm screw assembly rotatable in relation to said housing and including (i) a worm screw member having a pointed first end portion and a second opposite end portion and (ii) a drive member fixed in relation to said second opposite end portion and defining a connection head configured to be received by a rotatable output shaft of a power tool, said worm screw assembly being configured such that rotation of said drive member by said power tool causes rotation of said worm screw assembly;
a first gripper movable in relation to said housing and extending through said first gripper passage; and
a second gripper movable in relation to said housing and extending though said second gripper passage a first biaser connected to said first gripper; and
a second biaser connected to said second gripper,
Wherein said first gripper, said second gripper, said first biaser, and said second biaser are integrally formed as a single part from an elastomeric material and said first biaser and second biaser are located in said interior space.

11. The corkscrew assembly of claim 10 , wherein said connection head defines a hexagonal exterior periphery.

12. The corkscrew assembly of claim 10 , wherein said drive member defines a shaft portion extending from said connection head and connected to said second opposite end portion of said worm screw member.
