Abstract:
1. A device for extracting a cork from a bottle comprising: A generally T-shaped handle mounted on a housing having an upper end and a lower end, a shaft which is operatively connected to said housing for axial and rotational movement therewith, said shaft having a hollow passage with art air intake and an air exhausting hole, said shaft depending from said lower end of said housing for griping and penetrating the cork longitudinally; a pump configured to push air from said housing through said shaft into said bottle between the cork and the contents of the bottle such that the air pushed ha the bottle forces the cork out of the bottle in conjunction with force applied by pulling said T-shaped handle; and wherein said pump comprises of a trigger for moving a cylindrical piston between a first position at which the cylindrical piston is spaced from the lower end of the housing and a second position at which the cylindrical piston is closer to said lower end of said housing, wherein said trigger is a lever which extends downwardly from said T-shaped handle and is operatively arranged to be incorporated into a cavity in said T-shaped handle and moves within said cavity to engage with said cylindrical piston; a spring for urging said cylindrical piston towards said first position thereof; an annular one-way valve at the base of said cylindrical piston, wherein said annular one-way valve opens when said cylindrical piston is in said first position, to allow air to collect in said piston and wherein said annular one-way valve closes when said cylindrical piston is in said second position and seals air collected in said cylindrical piston to be forced in said air intake and out of said air exhausting hole and injected into the bottle to eject the cork from the bottle; and a stem married to said annular one-way valve, wherein said stem allows said annular one-way valve to remain in a correct position, sealed to the bottom of said cylindrical piston, when said trigger is engaged.
