  • Patent number: 6101899
    Abstract: An electrically powered corkscrew has an inclined handle of high ergonomic character to enable convenient and effective use when standing or seated, while ensuring a corkscrew of compact arrangement. The corkscrew has a de-briding cutter concealed in the butt of the handle for removing the usual foil seal from the cork. The cork extracting mechanism includes a dual purpose cork-stabilizing arrangement, including a pair of compression springs and guide posts to assist in countering rotation of the cork, and in assisting reverse operation of the corkscrew auger when discarding the cork.

  • Patent number: 6095075
    Abstract: A retractable boat line for mooring a boat is wound about a payoff reel contained within a stationary housing, which my be mounted beneath the exterior surfaces of the boat, for example within the hull, transom or gunnel. The invention provides a locking mechanism that latches into a guide wall of the payoff reel at a point remote from the edges of the guide wall to rotationally lock the payoff reel relative to the housing. The mooring line can thus be selectively extended to a desired length and remains locked to the selected length until the locking mechanism is disengaged.

  • Patent number: 5351579
    Abstract: A rechargeable electric corkscrew for removing a cork from a bottle comprises a reversible drive having a switch for switching the drive between rotation in a first sense and an opposite sense. A body houses the drive and a rechargeable power source and has a rotatably mounted auger extending in a longitudinal direction. A sleeve has a first end adapted for slidably mounting onto the body. The sleeve has a second end surrounding the auger comprising cantilevered members each having an abutment surface adapted to abut a mouth of the bottle. The cantilevered members are adapted to flex for positioning the abutment surfaces relative to each other about the mouth. The cantilevered members has a base end having a radial extent for stably supporting the corkscrew in an upright condition. The corkscrew is also provided with a cutter for cutting a foil wrapper which covers the mouth of the bottle.
