| 081300450 | Screw type | 8 |
| 20080271573 | Ratcheted Cork Screw - A corkscrew includes a ratcheting feature to facilitate insertion of the bit into a closure and a locking feature to facilitate removal of the bit from the closure. A corkscrew also includes a removable bit (e.g., a worm, auger, or the like). | 11-06-2008 |
| 20090241737 | Cork extractor - A cork extractor significantly reduces the countervailing forces that must be applied to a bottle during extraction of a cork by providing a handle having a rotational axis substantially perpendicular to the vertical, longitudinal axis of a cork as it is removed from a bottle. A handle rotates about an axis and comprises gripping portions on opposite sides of the rotational axis. The corkscrew is prevented from spiraling out of the cork during the application of upwardly directed forces independently of the screw carrier. | 10-01-2009 |
| 20090301261 | SNAP-TYPE CORKSCREW - The present invention refers to a snap-type corkscrew, i.e. a corkscrew that snaps open when it has to be used. A corkscrew according to the invention comprises a handle ( | 12-10-2009 |
| 20100095808 | Winch-type corkscrew assembly - An auger-type corkscrew is housed in a body with an opening for communicating with the cork in a wine bottle or the like. An auger tip is carried in the body and is adapted to be rotated and extended into and rotated and withdrawn out of contact with the cork. The drive mechanism is mounted in the body for rotating and extending and withdrawing the auger tip. A winch-type handle is mounted outside the body and in driving communication with the drive mechanism, whereby rotation of the winch-type handle activates the drive mechanism for rotating and extending and withdrawing the auger tip. | 04-22-2010 |
| 20110100164 | Self-Pulling Corkscrew - A self-pulling corkscrew is provided. The corkscrew includes a body comprised of a first arm extending downwardly from a central portion and a second arm extending downwardly from the central portion. The first and second arms each having an inner surface and an outer surface wherein the inner surfaces of the first arm and the second arm cooperatively define a bottle receiving cavity. The corkscrew further includes a first groove traversing at least a portion of the outer surface of the first arm and a second groove traversing at least a portion of the outer surface of the second arm. One of either the first and second grooves has a first depth at a proximate end of the groove and a second depth at a distal end of the groove. The corkscrew is further comprised of a sleeve, a handgrip and a screw. The sleeve is slidably engaged with the first and second arms and has a first inwardly projecting protrusion and a second inwardly projecting protrusion. The first protrusion cooperatively engages the first groove and the second protrusion cooperatively engages the second groove. The handgrip is attached to the body proximate the central portion, and the screw is coupled to the handgrip. The screw extends into the bottle receiving cavity between the inner surfaces of the first and second arms. | 05-05-2011 |
| 20110185859 | CORKSCREW - The corkscrew of the invention is specially designed to ensure optimum functionality, while being extremely easy to use and having great structural simplicity, with the consequent positive effects in terms of costs and lifetime of the corkscrew. To this end, the support arm ( | 08-04-2011 |
| 20110252924 | Corkscrew with unidirectional clutch drive - An improved corkscrew includes a unidirectional clutch mechanism that enables the user to grasp the corkscrew handle, place the screw tip impinging on the cork, and to rotate the handle reciprocally to advance the screw and embed it in the cork. The mechanism features a clutch spring that transfers rotation of the handle to the screw in one direction only. As a result, fatigue of the user's hand and wrist is substantially reduced, and repetitive stress injuries are diminished. | 10-20-2011 |
| 20150013500 | Level Corkscrew Having a Double Fulcrum and Method of Using Same - The invention relates to a corkscrew (T) including a handle ( | 01-15-2015 |
