Oh, patents! Multipurpose winged corkscrew

Copyright © Françoise Herrmann

Winged corkscrews comprising rack and pinion attached levers and central shaft, together with a worm (or helix spiral) at one end, have existed since the beginning of the 20th century. What is new in a multipurpose winged corkscrew is the added versatility of Swiss-knife-type tools that tuck into the base of the corkscrew handle. Secondary, Swiss-knife-type tools such as large, small, or serrated blades, can openers, bottle openers, screwdrivers, scissors, reamers, pins, chisels, metal files, peelers and cutters, plus more. 

Such a multifunctional corkscrew is recited in the European patent application, EP3130558A1, titled Winged corkscrew with one or more secondary utensils. An invention that primarily seeks to include an all-in-one solution to removing both the protective foil that surrounds the opening of the corked bottle, and the cork inserted inside the bottle neck.

The patent Figure 8 is included to the right. The patent Figure 8 depicts a perspective view of one embodiment of the winged corkscrew 100 with two hinged secondary tools, a blade and a pin (800 and 801) that are protracted from the base of the handle 125.

The patent Figure 8 further depicts, the handle portion 125, also designed to function as a bottle opener, with a hollow opening 175 and a lip 180 intended to engage and remove a bottle cap. The Figure 8 also depicts a central shaft 105, with helical rack 135, that engages with the gear teeth 145 and 150 of the levers 110, 115, to provide vertical movement (up and down) of the shaft 105, upon actuation of the levers 110, 115. The levers 110, 115 are attached to the shoulders 137, 138 of the corkscrew body 120, with pins 155, 160, enabling rotation of the levers 110, 115 and of the gear teeth 145, 150. The base of the multipurpose corkscrew 170 is designed to fit around the top portion of a bottle, through which the worm 140 will be inserted for removing the cork.

The abstract of the invention, also indexing the Figure 8, is  included below.
A winged corkscrew (100; 800; 900; 1000; 1100; 1200) with one or more secondary utensils. The winged corkscrew comprises: a shaft (105), body (120), two levers (110, 115), and two pins (155, 160). The shaft comprises: a handle portion (125), secondary utensils (130, 131), a rack portion (145), and a helical portion (140). The handle portion comprises an opening (175) and a lip (180) disposed along the inner edge of the opening. A secondary utensil such as a blade (802, 1002) is hingedly disposed between the handle portion and the rack portion, which is positioned adjacent to the helical portion. The body comprises: a through hole (136), base (170), and two shoulders (137, 138). The two levers pivotally engage with the two shoulders via the two pins. The shaft engages and extends through the through hole of the body, such that the helical portion of the shaft is disposed within the body. The base is substantially cylindrical and is adapted to engage with a neck portion of a bottle. [Abstract EP3130558A1]
