Abstract: A self-centering and self-gripping corkscrew is provided. A centering and locking mechanism is integrated into the bottle receiving opening of the corkscrew such that in one downward motion a bottleneck is securely gripped and automatically centered under the cork removing device (e.g., a worm screw). The centering and gripping mechanism is spring biased downward and utilizes compression techniques configured into an outer mechanism (contained within the bottle receiving opening of corkscrew) and the body of the corkscrew to simultaneously grip and align the bottle with the axis of the cork removing device. The locking mechanism is part of the centering mechanism and allows the corkscrew to remain locked onto the bottleneck (after centering and gripping) during activation of the cork removing device and removal of the corresponding cork. An upward motion opposite the locking motion disengages the mechanism, removing the corkscrew from the bottle.

Abstract: This invention is an improvement to be applied to certain known bottle openers, called automatic bottle openers, in which, in order for the extraction to take place it is essential that the closure offers sufficient friction on the worm. Otherwise, once the worm has penetrated the closure, at the point of extraction, it can unthread itself from the closure by means of an anti-clockwise rotary movement and the perforated closure remains inside the neck of the bottle. The invention solves the disadvantage and is characterised in that; if the friction of the closure on the worm is not sufficient, a mechanical system takes over automatically that stops the worm only in anti-clockwise rotary motion during the single extraction stage to then, in the process of the same upward movement, allow the restoration to anti-clockwise rotation so that that the worm can be released from the closure.

Abstract: A hand tool with a U-shaped cutout to slide into the groove at the top of a champagne bottle, and pivoted lever-arms above the cutout straddling the stopper of the bottle. Extractor links connected to these lever-arms, are hinged at the outer end, and have teeth across the inner end, which is aligned with the stopper. Squeezing the lever-arms together causes the extractor links to engage and compress that part of the stopper exposed above the top of the bottle. The extractor links are angled upward toward the toothed end, so that the resulting combined upward force of the two links on opposite sides of the stopper, cause it to be extruded upward. Repeated actuations may be used to remove the stopper completely. The tool grips, and retains the stopper when completely closed.

Abstract: A corkscrew incorporating a support arm with two articulated sections capable of acting independently and sequentially by resting on a bottle's mouth. The sections are connected to each other through a joint that has a spring that causes one of the sections to seek out the side or mouth of the bottle where it is to be positioned, without the need for a corkscrew user to deliberately perform this operation. The spring is set at the level of the articulated joint between the arm and body or handle, the ends of which form aligned and opposing pivots that emerge laterally from the body, where the arm incorporates a circumferential arrangement of notches over which the pivots must move during the swinging movement of the arm with respect to the body. This prevents undesired movement between the arm and the body, no matter what relative position is chosen for them.
