ABSTRACT:
BACKGROUND
The present invention relates to a force minimizing corkscrew that reduces the amount of force needed to open corked bottles.
In the sparkling wine and gaseous beverage field there is a need for a force minimizing corkscrew that reduces the amount of force needed to open corked bottles.
In the past, various type of cork removers have been introduced. The devices can be classified into two general groups. The first group are devices that require a users physical force to remove the cork from a bottle and the second group are devices that insert gas inside a bottle so that the cork is expelled due to pressure created within the bottle.
Two immediate problems that may arise with these devices are as follows: (1) the first type of devices prevent users that do not have the physical strength to open corked bottles, and (2) the second types of devices can be dangerous to the general public if misused.
Information relevant to attempts to address these problems can be found in U.S. Pat. Nos. 5,010,790, 4,377,096, 4,572,034, 2,522,219, 2,305,532, 396,286, and 382,005. However, each one of theses references suffers from one or more of the above disadvantages.
For the foregoing reasons, there is a need for a force minimizing corkscrew that requires a minimal amount of force to operate.
SUMMARY
The present invention is directed to an easily removable corkscrew that satisfies the following needs: the need to remove a cork from a bottle using a minimal amount of force, and the need to prevent accidents that may occur using cork removers that use gaseous pressure to remove corks. A force minimizing corkscrew having features of the present invention comprises a guiding holder having an upper and a lower side; a cork engaging means which comprises of a top, a middle, and a bottom part, wherein the top of said cork engaging means is inserted through said guiding holder; a force generating member, that has an upper and a lower side, that is attached to said top of said cork engaging means after the cork engaging member has been inserted through said guiding holder; and upper and lower bearings, wherein said upper bearings are placed between said lower part of said force generating member and said upper side of said guiding holder, and said lower bearings are placed between said lower side of said guiding holder and said middle part of said cork engaging means. The following parts are grooved and said grooves are circular so that when said upper and lower bearings are placed within said grooves and the force generating member is turned in either a clockwise or counterclockwise direction, the manual force required to remove a cork from a corked bottle will be minimized: said lower side of said force generating member, said upper side of said guiding holder, said lower side of said guiding holder, and said middle part of said cork engaging means. Furthermore, said lower part of said cork engaging means, after the force minimizing corkscrew has been assembled, will extend past the guiding holder so that the lower part of said cork engaging means can be screwed into the cork up until said guiding holder is flush with the lip of a corked bottle, once the lip of the corked bottle and said guiding holder are flush, the cork will internally be spiraled upward by said lower part of said cork engaging means until the cork is within said guiding holder. Said guiding holder may contain at least two friction means running parallel to said cork engaging means and said friction means being attached to said guiding holder.
An advantage of this invention is that it allows corked bottles to be opened using a minimal amount of force.
Another advantage of the invention is that the force minimizing corkscrew prevents accidents that may occur using pressure bottle openers.
