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.
- Improved articulated corkscrew, of the type incorporating a spiral worm intended to be axially inserted into the cork, joined in an articulated manner to a handle which in turn is joined in an articulated manner to an arm that rests on the rim of the bottle, forming a second-class lever, and in which the aforementioned support arm is made up of two sections joined to each other in an articulated manner, one as an extension of the other, characterized by the fact that on the swing axis of the two support arm sections a spring is set that extends between both support arm sections and tends to maintain the latter in an extreme, stable position in which the second support arm section seeks out, on its own, the rim of the bottle where it should be situated.
- Improved articulated corkscrew, according to claim 1, characterized by the fact that the aforementioned spring has two symmetrical halves, which taken together form a “U” shape, which through its central branch rests internally on the first section of the support arm;
- Improved articulated corkscrew, according to claim 1, characterized by the fact that in the area of the axis of the articulated joint between the arm and the handle, a transverse spring is set, whose ends form coaxial, opposing pivots that emerge substantially to the outside of the handle and that act on the inner face of the lateral branches of the “U” shape, corresponding to the arm, which has a plurality of notches that form a circumferential alignment concentric to the swing axis itself of the arm on the handle, notches that in a radial arrangement form internal retaining teeth for the aforementioned pivots, all in order to maintain stability in any relative position between the arm and the handle, especially after wear and tear occurs in the axis of the articulated joint between these components.
