1. Field of the Invention
This invention is generally related to corkscrews for removing corks from wine bottles and the like and is specifically directed to a corkscrew assembly having a mechanized system for an auger type corkscrew.
2. Discussion of Prior Art
Corkscrews for removing the cork from a wine bottle and the like have been available for at least two centuries. S. Henshall patented an auger-type corkscrew in 1895 and the basic concept has not changed since that time. Numerous improvements have been made over the years.
Herbert Allen has received a patent for an improvement in the basic auger type screw and pull corkscrew as disclosed in U.S. Pat. No. 4,291,597 issued on Sep. 29, 1981. Mr. Allen has also received a patent on a lever-action corkscrew, U.S. Pat. No. 4,253,351 issued on Mar. 31, 1981.
Mr. Allen has also received numerous patents on variations of these designs, wherein the auger type screw is encapsulated in an outer sheath or cover which is adapted to fit over the mouth opening of the wine bottle, see U.S. Pat. No. 4,276,789 issued on Jul. 7, 1981; U.S. Pat. No. 4,377,096 issued on Mar. 22, 1983; U.S. Pat. No. 4,429,444 issued on Feb. 7, 1984; DES 293,414 issued on Dec. 29, 1987; U.S. Pat. No. 4,800,784 issued on Jan. 31, 1989; and U.S. Pat. No. 4,703,673 issued on Nov. 3, 1987.
In addition, Mr. Allen has two patents on a cork puller which does not rely on penetrating the cork but instead relies on twisting torque and a pulling action, see U.S. Pat. No. 4,800,783 issued on Jan. 31, 1989 and U.S. Pat. No. 5,042,331 issued on Aug. 27, 1991.
With the exception of the lever action design disclosed in U.S. Pat. No. 4,253,351 and the torque twist and pull designs shown in U.S. Pat. Nos. 4,800,783 and 5,042,331 all of the Allen corkscrews rely on an auger type tip for penetrating the cork and a twisting action wherein the twisting force is applied while gripping the corkscrew in a manner which is in axial alignment with the auger tip.
The inventor of the subject application was recently awarded U.S. Pat. No. 8,011,276. As shown in that patent, The invention not only provides a decorative corkscrew but also takes advantage of providing a rotary or twisting action outward of the auger axis, providing additional leverage for making it easier to twist the cork by applying a lower force. This is particularly advantageous when a person with small hands or limited strength is attempting to remove the cork from a bottle.
As shown in the patent, the corkscrew is housed in an attractive housing designed in appearance to resemble a nautical winch mounting block. The rotating actuator handle is in the shape of a winch handle. The corkscrew mechanism is in communication with the actuator handle and is housed in the mounting block housing. The winch handle may be oriented for turning about either a vertical or a horizontal axis.
The winch handle configuration provides additional torque when turning the corkscrew, facilitating the removal of the cork from a bottle. In addition, the winch handle design and decorative mounting block provide a decorative accent piece with the corkscrew being hidden from view when not in use.
The corkscrew assembly includes a body having an opening for communicating with the cork in the bottle. 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 handle activates the drive mechanism for rotating and extending and withdrawing the auger tip. The winch-type handle may be mounted either for rotation about a vertical axis or about a horizontal axis. When mounted for horizontal rotation a differential gear assembly is mounted in the body and in communication with both the drive mechanism and the winch-type handle for translating the horizontal rotation of the winch handle to a vertical rotation in communication with the drive mechanism.
The subject invention is directed to an electrically operated winch-type corkscrew for a wine bottle cork and the like and is an improvement over my aforementioned U.S. Pat. No. 8,011,276. The “winch handle” has been replaced with a geared electric motor assembly for turning and lifting the cork out of a stationary wine bottle.
In its preferred embodiment the invention is free standing, permitting the wine bottle to be placed in a receptive opening and attached to the motorized screw mechanism. The design is intended to provide an attractive accent accessory that can be displayed when not in use.
Specifically, the wine bottle opener of the subject invention is a counter-top appliance (similar in size to a typical blender) in which the operator inserts the wine bottle into the base and then locks it in place and raises it to the winch mechanism. The winch mechanism is then activated to twist, lift and remove the cork.
An electric motor is geared with the winch mechanism to rotate the winch when activated, making the system automatic. With the bottle resting on the base of the system and locked in place to prevent rotation, there is not any need for the operator to hold the neck of the bottle during the uncorking process.

In the preferred embodiment the motor 50 is located in a motor housing 52 which in turn is located in the crank housing 46. A battery compartment 54 may be included for housing batteries 56 to provide power for the motor 50. In the alternative, the power may be supplied by typical house current or the like using a power cord and transformer (not shown). When a battery pack is used, an access door 58 may be provided.
In the illustrated embodiment, the winch mechanism comprises an outer housing or drum 62 with a central hollow core or channel 64 for housing the crank housing 46, motor assembly 50 and 52 and the cork gripper assembly 40 and spring 44. When the motor 50 is actuated, the cork gripper 40, which is in contact with the cork 30, rotates the corks and turns it out of the bottle.
It is desirable to provide centering bearings to assure smooth rotation between the outer drum 60 and the winch or crank mechanism 46. Control electronics may be housed in the outer drum, as indicated at 68. The screw mechanism 70 lifts and lowers the cork gripper when the cork gripper 40 is activated to rotate by the motor 50. The control electronics control the rotational direction of the cork gripper. The control electronics may also be used to engage and disengage a bottle lock mechanism 34 when employed, see
